Specific embodiment
Below with reference to embodiment shown in the drawings, the present invention will be described in detail.But these embodiments are simultaneously unlimited
The system present invention, the transformation in structure or function that those skilled in the art are made according to these embodiments include
Within the scope of the present invention.
The fixed dustproof construction of dust bag is a kind of structure for dust bag to be fixed in the dust collecting cavity of dust catcher.
Referring to figure 2. to shown in Fig. 5, the first better embodiment of dustproof construction is fixed for dust bag of the present invention.In the present embodiment, collection
The fixed dustproof construction of dirt bag includes insert rack 30 and the plate being connected in insert rack 30 50, and insert rack 30 includes main body 31, is set to
Sliding slot 32a, 32b of main body two sides and it is set to the baffle 34 that bottom part body is located at the end sliding slot 32a, 32b, in main body 31
Portion is equipped with first through hole 311, and the middle part of plate 50 is equipped with second through-hole 51 corresponding with first through hole 311, insert rack 30 and plate
The sealing ring 40 around first through hole 311 is equipped between 50, sliding slot 32a, 32b insertion of the plate 50 along two sides is connected to insert rack
30.Wherein, the direction that plate 50 is inserted into along sliding slot 32a, 32b is the up and down direction of insert rack 30, the two of sliding slot 32a, 32b distribution
The direction of side is the left and right directions of insert rack 30.The side that insert rack 30 connects plate 50 is the front side of insert rack 30, the opposite other side
For the rear side of insert rack 30.The distance between sliding slot antetheca 321a, 321b and main body 31 n are the width of sliding slot 32a, 32b, i.e. edge
Perpendicular to main body direction, the distance between sliding slot antetheca 321a, 321b and main body 31.The thickness of plate 50 is less than sliding slot
The width n of 32a, 32b.There is convex edge 312, sealing ring 40 is mounted on convex edge 312, sliding slot 32a, 32b on the outside of first through hole 311
Width n be less than sealing ring 40(nature) thickness and the sum of the thickness of plate 50, that is to say, that sliding slot 32a, 32b limit
The minimum range between plate 50 and main body 31 is determined, the thickness of sealing ring 40 is typically larger than the minimum range.So in plate
Sealing ring 40 can be compressed when 50 insertion sliding slot 32a, 32b, promotes the sealing performance between insert rack 30 and plate 50.
As shown in Figure 4 and Figure 5, width n and sealing when plate 50 is mounted in insert rack 30, due to sliding slot 32a, 32b
Enclose 40(nature) the difference of thickness be less than the thickness of plate 50, so will lead to 50 deformation of plate, formed intermediate projections,
Radian of the left and right sides close to main body 31.In this way, the radian makes the plate of 51 left and right sides of the second through-hole compress 40 He of sealing ring
Main body 31.The radian makes the gap enlargement between the plate and main body 31 of about 51 two sides of the second through-hole in order to prevent, to lead
Seal failure is caused, it is preferred in the present embodiment, the first limitation machine is respectively equipped with along the upper and lower of 50 direction of insertion of plate in insert rack 30
Structure and the second limiting mechanism, the first limiting mechanism and the second limiting mechanism are able to limitation plate 50 and move up and down,
And the top edge that the first limiting mechanism limits plate 50 is less than the thickness of sealing ring 40, the second limitation machine to the distance of main body 31
The lower edge that structure limits plate 50 is less than the thickness of sealing ring 40 to the distance of main body 31.Pass through the first limiting mechanism of setting and the
Two limiting mechanisms can be fixed reliably after so that plate 50 is inserted into sliding slot 32a, 32b, plate 50 is prevented to be displaced, and
Plate 50 can be made to generate radian along up and down direction, which makes the plate of about 51 two sides of the second through-hole compress sealing ring 40
With insert rack 30, achieve the effect that prevent about 51 both sides sealing of the second through-hole from failing.
With continued reference to Fig. 4 and Fig. 5, preferred in the present embodiment, the first limiting mechanism is preferably arranged on 30 top of insert rack
Top hook 36, elastically-deformable top hook can preferably occur, plate can be made to be easier to be inserted by its elastic deformation；
Second limiting mechanism is preferably arranged on the bottom hook 37 on 30 bottom baffle 34 of insert rack, between top hook 36 and main body 31
Distance m1 be less than sliding slot 32a, 32b width n；The distance between bottom hook 37 and main body 31 m2 are less than sliding slot 32a, 32b
Width n.In this way, plate 50 is pressed to main body by top hook 36 and bottom hook 37 when plate 50 is inserted into sliding slot 32a, 32b
31, make 50 deformation of plate, forms radian in the up-down direction.Specifically, top hook 36 and bottom hook 37 are all respectively set
Two, along the center symmetric setting of main body 31.In main body among two top hooks 36, it is provided with guiding rib 35, is used for
It is oriented to plate 50 and is inserted into sliding slot 32a, 32b, therefore the front of guiding rib 35 is provided with inclined-plane or cambered surface, for facilitating guiding to insert
The insertion of plate 50.In addition, sliding slot 32a, 32b antetheca form horn-like sliding slot mouth 38 close to the part of plate insert port, it is conducive to
The insertion of plate 50.
As shown in Figure 6 and Figure 7, in currently preferred second embodiment, the first limiting mechanism is preferably mounted to main body
Elastic clip 60 on 31, one end of elastic clip 60 are fixed in main body 31, the top of the other end clamping plate 50 of elastic clip 60
Edge, elastic clip 60 include being set to the clamping part 61 of 31 front of main body and being set to what 31 rear portion of main body was connect with clamping part 61
Torsional spring portion 62, clamping part 61 clamp plate 50 with respect to main body 31 under the resilient force in torsional spring portion 62.Wherein, elastic clip 60
Can be set two, the middle part relative to main body is symmetrically set to the two sides of main body 31, certainly, and in the present embodiment, two
Clamping part 61 can connect together, operate when being clamped or being unclamped more convenient.Preferably, elastic clip 60 is
It is wholely set, specifically, elastic clip 60 is to be bent using an one metal wire.
As shown in Figure 8 and Figure 9, in currently preferred 3rd embodiment, the top of plate 50, which has, facilitates operator to take
The folding part 52 pinched, in the aforementioned embodiment, folding part 52 and plate 50 are set to same plane, and in the present embodiment, folding part 52 is arranged
Turn forward in 50 top upper limb of plate and relative to insert rack 30, convenient for plate 50 is dismounted, i.e., along sliding slot 32a,
32b is pushed inward or is pulled outwardly.Further, upward elastic slice 70 is equipped on bottom baffle 34, the insertion of plate 50 is inserted
Elastic slice 70 is pushed after frame 30, so that 50 upper limb of plate is crossed 30 top hook 36 of insert rack, then plate 50 is pushed away inward, is caught in top
Hook 36, back card/back board 50 of letting go are fixed by 70 bullet of elastic slice up automatically.When dismantling plate 50, being affectedly bashful folding part 52 makes plate 50
Upper limb separated with top hook 36,70 elastic force of elastic slice is released to plate 50 and applies upward power so that disassembly plate 50
It is more laborsaving.Specifically, the both ends of elastic slice 70 are fastened in the slot of 37 lower part of bottom hook, provided to the deformation of elastic slice 70 flexible
Space, while preventing elastic slice 70 from falling off from insert rack 30.In the present embodiment, elastic slice 70 is plastic material, with insert rack 30 1
It is body formed.Certainly, elastic slice can also be substituted by other way, pressure spring on bottom baffle such as be arranged in, along trough width side
To the elastic string etc. of setting, as long as the elastic element can compress plate along the direction opposite with plate direction of insertion
Implement.
