Abstract

A kind of series connection shear shank, including outrigger, internal frame and series connection frame, inside and outside frame all have two the second bars of the first bar and the first bar both ends and two the second bar fronts are bent out two be not attached to third bar, and there is perforation among two the second bars, there is opening between two third bars；Frame of connecting has the first bar of series connection, and two second bars of series connection at the first bar both ends of series connection and two the second bar fronts of series connection are bent to form two series connection third bars；Inside and outside frame is mutually nested after keeping open direction consistent, and is cascaded after passing through perforation by series connection frame third bar, and the first bar of series connection does not close the opening between two third bars close to internal frame or the first bar of outrigger.

Description

A kind of series connection shear shank

Technical field

The utility model is related to keyboard technical fields, and particularly, the utility model is suitably mounted to about one kind Shear shank inside ultra-thin key.

Background technology

Currently, those skilled in the art has invented a kind of ultra-thin shear shank, referring to application No. is 201520821698.3 Patent, the thickness of the ultra-thin shear shank less than 0.8 millimeter, be less than 2.5 millimeters of common plastics shear shank thickness, be very suitable for It applies in ultra-thin keyboard.In order to reduce thickness, which is to be bent into inside and outside holder using metal capillary, The corresponding position of two side axles of one of holder welds two independent pivotals, gets and wears in the corresponding position of another holder Hole, last pivot pass through perforation that two holder inlaid-assemblings get up.

Since the diameter of metal tube only has the diameter of pivot there was only 0.25 millimeter, metal pipe diameter less than 0.8 millimeter, so The case where contraposition is inaccurate frequent occurrence during pivot is welded in metal tube side axle, not prison welding, reduces this kind The qualification rate of ultra-thin shear shank finished product, so, it is now desired to a kind of ultra-thin shear shank for assembling of being more convenient for.

Invention content

The utility model provides a kind of series connection shear shank, including outrigger, internal frame and series connection frame.

Inside and outside frame all has the first bar, two second bars at the first bar both ends, bend out two of two the second bar fronts It is not attached to third bar, there is perforation among two the second bars, there is opening between two third bars.

Frame of connecting has the first bar of series connection, two second bars of series connection at the first bar both ends of connecting, before two the second bars of series connection Portion is bent to form two disjunct series connection third bars.

The inside and outside frame of the shear shank is mutually nested and open direction is consistent, and series connection, which is placed in internal frame, encloses or outrigger periphery, Inside and outside frame is cascaded by two series connection third bars after penetrating two groups of inside and outside perforation.

Preferably, the first bar of series connection does not close the opening between two third bars close to internal frame or the first bar of outrigger.

Description of the drawings

The embodiment of the utility model is described in detail below in conjunction with the accompanying drawings.

Fig. 1 is outrigger structure chart.

Fig. 2 is inner rack structure figure.

Fig. 3 is series connection frame first structure figure, and series connection third bar therein bends inwards.

Fig. 4 is series connection the second structure chart of frame, series connection third bar outward bending therein.

Fig. 5 is the structure chart under second form of shear shank.

Fig. 6 is the structure chart under first form of shear shank.

Specific implementation mode

A kind of shear shank, including outrigger, internal frame and series connection frame.

Referring to Fig. 1, shown in Fig. 2.

Outrigger has outer first bar 11, two outer second bars 12 at outer first bar, 11 both ends, two outer second bar, 12 fronts The two outer third bars 13 bent out also have outer perforation 14, two disjunct outer third bars among two outer second bars 12 Have outer open 15 between 13.

The structure of internal frame is identical as outrigger, and only specification is slightly less than outrigger, equally includes interior first bar 21, interior first bar 21 Second bar 22 in two of both ends, two interior third bars 23 that 22 front of the second bar is bent out in two, the second bar 22 in two It is intermediate that also there is interior perforation 24, have interior open 25 between two disjunct interior third bars 23.

Referring to Fig. 3, shown in Fig. 4.

Frame of connecting has the first bar 31 of series connection, two second bars 32 of series connection at series connection the first bar 31 both ends, two series connection the Two bars, 32 front is bent to form two series connection third bars 33, and unlike inside and outside frame, there is no any on the second bar 32 of connecting Perforation, moreover, series connection frame tool, there are two types of structure, two series connection third bars 33 of first structure, frame of connecting bend inwards；Second knot Structure, two 33 outward bendings of series connection third bar of frame of connecting.

Referring to Fig. 5, shown in Fig. 6.

After inside and outside frame nesting, interior perforation 24 and outer perforation 14 correspond, and two series connection third bars 33 of frame of connecting penetrate Perforation 24 and outer perforation 14, inside and outside frame is cascaded in two groups, at this point, interior open 25 is identical with outer open 15 direction, It is open that entire shear shank is collectively formed.

Because there are two types of structures for frame of connecting, also there are two types of forms for entire shear shank.

First form, as shown in figure 5, after inside and outside frame nesting, series connection frame is located at the periphery of outrigger, two strings of frame of connecting Connection third bar 33 inwardly penetrates perforation 24 and outer perforation 14 in two groups.

Second form, as shown in fig. 6, after inside and outside frame nesting, series connection frame is located at the interior of internal frame and encloses, two strings of frame of connecting Connection third bar 33 penetrates perforation 24 and outer perforation 14 in two groups outward.

Under both the above form, the first bar of series connection 31 for frame of connecting or close outer first bar 11, or close to interior first Bar 21 will not close outer open 15 or interior open 25 in a word.

It is the main contents of utility model above, all modifications and transformation carried out according to its design should all be fallen in its protection Within the scope of.

Claims

1. a kind of series connection shear shank, which is characterized in that including outrigger, internal frame and series connection frame,
