Abstract
The utility model discloses a clamp type (tubeless) tyre valve sleeve cap, which comprises a cap head and a cap body. Wherein, the cap head and the cap body are formed into a whole. A joint between inner walls of the cap head and the cap body is provided with a step. The sleeve cap is connected with a vale through threads to press the step of the inner wall of the sleeve cap onto an elastomer end of the valve. A conical inner wall of the sleeve cap body closely contacts the elastomer of the valve. Based on the structure above, the sleeve cap can not only enhance hermetic performance of the tyre valve to prevent fall-off but also provide decorative and dustproof functions as a practical industrial product.
Description
Technical field
The utility model relates to the protective device of a kind of vehicle with buckle-type (inner tube free) tire valve.
Background technology
The vehicle of prior art is generally dust cap with the protective device of buckle-type (inner tube free) tire valve, can directly be screwed on the body of tire tube valve, and its effect mainly is to prevent dust; Sometimes for attractive in appearance, usually be socketed with metal covering at the tire tube valve body by the dust cap bottom, the function singleness of dust cap and metal covering, dust cap can only work to prevent that dust and foreign material from entering the tire tube valve inner chamber, metal covering can only play decoration function, and productive costs is higher, and dust cap when vehicle operating or inflation of tire often lose easily when safeguarding.
The utility model content
The purpose of this utility model is to overcome the deficiency of prior art, a kind of protective device that is used for buckle-type (inner tube free) tire valve is provided, this protective device can strengthen the close airway dysfunction of tire valve, and difficult drop-off, and still has decoration, antisoiling effect.
Buckle-type of the present utility model (inner tube free) tire valve sleeve cap, comprise cap head, cap body, cap head, cap body are one, and the inwall of cap head has a negative thread, the inwall joint of cap head, cap body has a step, and the cavity shape that cap body inwall forms is a cone.
Described cap head profile is the hexagonal body.
After adopting above-mentioned structure, buckle-type (inner tube free) tire valve sleeve cap can directly be screwed on the tire tube valve body, make the inwall and the tire tube valve elastic body closed contact of sleeve cap cap body, both but actv. prevented the chronic leakage of tire tube valve, make sleeve cap difficult drop-off when power actuated vehicle moves again, because cap head, the cap bodily form are integral, and have also reduced manufacturing cost effectively.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is the running condition figure of buckle-type (inner tube free) tire valve sleeve cap;
Fig. 2 is the structure enlarged diagram of buckle-type (inner tube free) tire valve sleeve cap.
The specific embodiment
Referring to Fig. 1, shown in Figure 2, buckle-type of the present utility model (inner tube free) tire valve sleeve cap, comprise cap head 1, cap body 2, cap head 1, cap body 2 are one, the inwall 11 of cap head 1 has a negative thread 12, cap head 1 profile is a hexagonal body 13, and the inwall joint of cap head 1, cap body 2 has a step 21, and the inner chamber of cap body 2 is a cone shape.In running condition, hexagonal body 13 by rotation sleeve cap cap head 1, the negative thread 12 of cap head 1 inwall 11 is spun mutually with the outside thread 31 of tire tube valve body 3 upper ends, the step 21 of the inwall joint of sleeve cap frieze rail 1, cap body 2 is pressed on the elastic body termination 32 of tire tube valve body 3, the cone inwall 22 of sleeve cap cap body 2 and elastic body 33 closed contacts of tire tube valve body 3.
