Abstract
The utility model discloses a kind of high-strength valve cock, including Valve tip body, valve inside and dust cap, internal thread segment is machined with the inner chamber of the Valve tip body for the valve inside that spins, the external thread section for starting from its end is machined with the outer cylinder of Valve tip body and is connected the resigning straightway of external thread section afterbody for the dust cap that spins, the length of the external thread section is 2/5 3/5 of dental length in dust cap, and the interior tooth crest clearance of the resigning straightway and dust cap coordinates.The utility model can effectively reduce stress and concentrate and cause Valve tip body in the breakage problem of its internal thread segment root, improve the reliability of product.
Description
Technical field
Tire art is the utility model is related to, more particularly to a kind of high-strength valve cock.
Background technology
The function of valve cock is to give tire inflation/deflation, and maintains the sealing after tyre inflating.Valve cock is typically by valve cock
Body, three major parts of valve inside and dust cap form, and the outer dental length on existing Valve tip body is longer, and its interior tooth needs to lock
Air-distributing valve core, as shown in figure 1, the position (i.e. in figure at A) corresponding to interior tooth root in Valve tip body is easily because wall thickness mistake
Thin and stress concentration and be broken.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of high-strength valve cock.
To achieve the above object, the utility model uses following technical scheme：
A kind of high-strength valve cock, including Valve tip body, valve inside and dust cap, in the inner chamber of the Valve tip body
Internal thread segment is machined with for the valve inside that spins, be machined with the outer cylinder of Valve tip body the external thread section that starts from its end and
It is connected the resigning straightway of external thread section afterbody for the dust cap that spins, the length of the external thread section is in dust cap
The 2/5-3/5 of dental length, the interior tooth crest clearance of the resigning straightway and dust cap coordinate.
Preferably, the length of the external thread section is 1/2 of dental length in valve cock.
After adopting the above technical scheme, the utility model compared with background technology, has the following advantages that：By on Valve tip body
External thread section shorten, the part that is shortened of external thread section is substituted with resigning straightway, in the case where not influenceing use, avoided
The concentration of stress tooth root in Valve tip body, the resistance to compression of Valve tip body and anti-twisting property improve, not easy to break, and to preparing
Cost is nearly free from influence, without existing product accessories are adjusted with (valve inside and dust cap).
Brief description of the drawings
Fig. 1 is the structural representation of existing Valve tip body；
Fig. 2 is this practical high-strength Valve tip body schematic diagram；
Fig. 3 is this practical high-strength valve cock general assembly drawing.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
Embodiment
As shown in figure 1, a kind of high-strength valve cock, including Valve tip body 1, valve inside 2 and dust cap 3, valve cock
Internal thread segment 11 is machined with the inner chamber of body 1 for the valve inside 2 that spins, is machined with the outer cylinder of Valve tip body 1 and starts from it
The external thread section 12 of end and the resigning straightway 13 of linking external thread section afterbody are for the dust cap 3 that spins.External thread section
12 length is the 2/5-3/5 of the interior dental length of dust cap 3, and the length of external thread section 12 is valve cock interior tooth in the present embodiment
The 1/2 of length, the interior tooth crest clearance of the resigning straightway and dust cap coordinate.
It is described above, the only preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should
It is defined by scope of the claims.
