The utility model discloses set up recess assembly O type circle in the assembly portion of inflating valve rod root, set up assembly guide and direction assembly axle at the root, car rim is through the assembly guide easily leading-in, location in the direction assembly is epaxial for sealing member and rim hole reside in the best position, and the assembly is easy, and the location is convenient, and is sealed effectual.
Description
Technical Field
The utility model relates to a hard guiding orientation's pressing mode inflating valve belongs to the auto parts field.
Background
When the existing compression type inflating valve is assembled with an automobile rim, a T-shaped rubber pad or an O-shaped ring is matched for sealing, the rubber pad part of the matched T-shaped rubber pad has a guiding effect when the T-shaped rubber pad is installed, but the rubber pad is soft, and if the rubber pad is not well assembled with the rim, or a defect on the rim can cause the product to be improperly assembled or the rubber pad to be damaged. And O type circle does not have the function of location, can let product assembly back inflating valve axis and rim hole axis do not coincide and the product is not placed in the middle, leads to gas leakage risk, exists not enoughly.
SUMMERY OF THE UTILITY MODEL
Not enough to the aforesaid, the utility model provides a hard guiding orientation's compact form inflating valve, the utility model discloses a technical scheme as follows:
the utility model provides a hard guiding orientation's compact form inflating valve, its includes the inflating valve pole, the root of inflating valve pole has a columniform assembly portion of evagination, be equipped with the round recess on the up end of assembly portion, be equipped with O type circle in the recess, the inflating valve pole corresponds the inner wall position of recess has a columniform assembly guiding axle, the inflating valve pole corresponds the up end of assembly guiding axle has the assembly guiding portion of a round platform shape, assembly guiding axle and automobile rim hole clearance fit, the lower terminal surface diameter of assembly guiding portion with the diameter of assembly guiding axle equals.
Compared with the prior art, the beneficial effects of the utility model reside in that: the utility model discloses set up the groove assembly O type circle in the assembly portion of valve stem root, set up assembly guide portion and direction assembly axle at the root, the car rim is easily led in, is fixed a position on the direction assembly axle through the assembly guide portion, makes sealing member and rim hole reside in the best position; set up O type circle and realize the radial seal of rim and the inflating valve body of rod, the rim does not need the sealed of sealing rubber spare with the axial contact department of the inflating valve body of rod, reduces the improper or rubber spare probability of damaging of product assembly.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is an enlarged view of the structure at A in FIG. 1;
fig. 3 is the utility model discloses with car rim assembly structure schematic diagram.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
Example (b):
referring to fig. 1-3, the hard-guiding and positioning compression type valve comprises a valve rod 1, wherein a cylindrical protruding assembling portion 2 is arranged at the root of the valve rod 1, a circle of groove is arranged on the upper end face of the assembling portion 2, an O-ring 4 is assembled in the groove, a cylindrical assembling guide shaft 5 is arranged on the inner wall of the valve rod 1 corresponding to the groove, a truncated cone-shaped assembling guide portion 6 is arranged on the upper end face of the valve rod 1 corresponding to the assembling guide shaft 5, the assembling guide shaft 5 is in clearance fit with a rim hole 3 of an automobile, and the diameter of the lower end face of the assembling guide portion 6 is equal to the diameter of the assembling guide shaft 5.
The utility model discloses set up the groove assembly O type circle in the assembly portion of valve stem root, set up assembly guide portion and direction assembly axle at the root, the car rim is easily led in, is fixed a position on the direction assembly axle through the assembly guide portion, makes sealing member and rim hole reside in the best position; set up O type circle and realize the radial seal of rim and the inflating valve body of rod, the rim does not need the sealed of sealing rubber spare with the axial contact department of the inflating valve body of rod, reduces the improper or rubber spare probability of damaging of product assembly.
The foregoing is a preferred embodiment of the present invention, and it should be noted that for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
