Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clear, complete description, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on this it is practical in embodiment, those of ordinary skill in the art are without creative labor
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment
Shown in referring to Fig.1~Fig. 3, the utility model discloses a kind of bulb plungers, including plunger tube 10, spring 30 and ball
Head.
Wherein, plunger tube 10 includes that plunger head 11, plunger middle part and plunger tail 12, the internal diameter of plunger head 11 are less than
Internal diameter in the middle part of plunger, the plunger tail 12 are provided with limiting slot 121.
The inside of plunger tube 10 is arranged in spring 30, and spring 30 includes spring head 302 and spring tail portion, spring head
302 abut bulb, and spring tail portion last lap increases to form spring retainer end 301, and the spring retainer end 301 is fastened on
In the limiting slot 121.Since spring retainer end 301 is fastened in limiting slot 121, spring tail portion is tightly tied with plunger tail 12
Structure, then spring 30 will not be dropped out from plunger tube 10.
One end of bulb is arranged in plunger tube 10, and the other end of bulb is protruding by plunger head 11, plunger head
11 pairs of bulbs are limited so that bulb is without departing from plunger tube.
As shown in Figure 1, in one embodiment, spheroid form can be selected in bulb.Bulb is spheroid form, and the diameter of bulb is big
In the internal diameter of plunger head, the diameter of bulb is less than the internal diameter in the middle part of plunger.
As shown in Fig. 2, in another embodiment, bulb positive stop end has can be set in bulb.Bulb includes 20 He of sphere end
It matches and can be slidably reciprocated in the middle part of bulb positive stop end 21, positive stop end and plunger in the middle part of plunger, sphere end 20 is fixedly installed
On bulb positive stop end 21 and sphere end 20 is protruding by plunger tube 10.Since the outer diameter of bulb positive stop end 21 is greater than sphere end
20, and matched in the middle part of bulb positive stop end 21 and plunger, the internal diameter in the middle part of plunger is greater than plunger head 11, such bulb positive stop end
21 can limit bulb, even if the sphere end 20 of bulb is worn, bulb will not be dropped out.
Bulb further includes columnar protruding end 22, and protruding end 22 connect with positive stop end and is arranged towards the tail portion of spring, convex
Origin or beginning 22 is threaded through spring inner.Protruding end 22 plays the role of limit plunger to spring, and spring is set in protruding end 22, more surely
Gu；And protruding end 22 also acts as the effect of structure compensation to the device.
Plunger tail 12 is provided with baffle 40, and baffle 40 is arranged in limiting slot 121, and baffle 121 abuts spring retainer end
301.Baffle can reinforce riveted effect, and be closed inner space, can be grease proofing with dustproof and waterproof.
The front end turnery processing of plunger tube 10 forms plunger head 11.The rear end riveted of plunger tube 10 forms plunger tail
12.Traditional plunger head 11 is what riveted was formed, and what the application plunger head 11 was formed by turnery processing, reinforcing finishes
Structure is not in that bulb slightly wears and just drops out.Relative to traditional plunger tube 10, in the application in the middle part of plunger and plunger tail
Portion 12 do tube wall skiving processing, then be unlikely to again when 12 riveted of plunger tail because tube wall is too thick and defective to staking.
The prior art is compared, the beneficial effects of the utility model are:
The utility model spring tail portion last lap increases to form spring retainer end 301, and spring retainer end 301 is fastened on
In limiting slot 121, spring tail end is tightly combined with plunger tail 12, and spring will not drop out.
Bulb positive stop end 21 is provided on the utility model bulb, bulb positive stop end 21 and plunger middle part match and can
It slidably reciprocates in the middle part of plunger, and the internal diameter of plunger head 11 is less than the internal diameter in the middle part of plunger, then being arranged in bulb positive stop end
Sphere end 20 on 21 will not drop out abrasion.
The utility model is practical, and bulb and spring will not drop out, and prolongs the service life.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new
Type.Various modifications to these embodiments will be readily apparent to those skilled in the art, and determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
This, the present invention will not be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The widest scope consistent with novel point.
