Description
Technical field
The utility model belongs to valve cock technical field, particularly relates to a kind of automobile clamp-in valve.
Background technique
Valve cock is for gas in charge and discharge tire, and the one-way cock that tire internal air pressure can be kept stable.Nowadays the tire that automobile uses is tubeless tires substantially, and structurally valve cock and tire are separated from each other, and valve cock is installed on wheel rim.Due to clamp-in valve possess that not easily oxidized, tightness is good, the advantage such as reusable after dismounting, be thus widely used on tubeless tires.Clamp-in valve comprises mouth body, and mouth body comprises the mouth body rod and mouth body chassis that are set to one.
At present, the mouth body chassis structure of the clamp-in valve used in a standard has three classes on the whole:
First kind mouth body chassis is outer-hexagonal structure, realizes mouth body fix during assembling by outer hexagonal spanner.This class formation mouth body is when assembling, due to outer hexagonal spanner shape, inconvenient when inserting wheel rim and using.In addition, this type of mouth body difficulty of processing is relatively large, and quality is wayward, and cost is relatively high.
Equations of The Second Kind mouth body chassis is round structure, in the groove milling of mouth body tray bottom, fixes groove milling position realize mouth body and fix by a word spanner.This class formation is when assembling, and because yi word pattern spanner is without the arm of force, the moment that need use when tightening hexagon nut is comparatively large, or because of groove milling position, macrolesion mouth body chassis of exerting oneself, affects follow-up use.Simultaneously because yi word pattern spanner is not easily located, moment of torsion does not reach requirement, easily causes wheel rim hole to leak gas, affects traffic safety.
3rd class mouth body chassis is round structure, and mouth body tray bottom, without any processing, realizes mouth body fix by manually holding mouth body rod portion during assembling.This class formation is when assembling, and when holding mouth body rod portion, gripping force is little, easily skids, causes mounting torque value less than normal or not up to standard.Gripping force high pulling torque can reach requirement, but easily makes mouth rod bending, fracture, causes the defective or gas leakage of angle, and mouth bar and wheel rim can be made to cause interference, inflation inconvenience.Manually hold simultaneously and be easy to fatigue, labor intensity is larger.
Model utility content
Technical problem to be solved in the utility model is: provide a kind of clamp-in valve, fixes inconvenient technical problem to solve lip-syncing body in existing valve cock assembly process.
For solving the problems of the technologies described above, the technical solution of the utility model is: clamp-in valve, comprise: mouth body, described mouth body comprises the mouth body rod and mouth body chassis that are set to one, described mouth body is provided with air vent, described air vent runs through whole described mouth body from the initial end face on described mouth body chassis, and described air vent is provided with the spanner cavity for holding spanner extended inward from the starting point face on described mouth body chassis.
Improve as one, described spanner cavity is interior prism cavity.
As further improvement, described spanner cavity is interior hexagonal cavity.
After have employed technique scheme, the beneficial effects of the utility model are: because clamp-in valve comprises mouth body, and described mouth body comprises mouth body rod and mouth body chassis, and described mouth body is provided with air vent, described air vent is provided with spanner cavity, thus, in assembly process, adopt the spanner suitable with spanner cavity shape, be inserted into lip-syncing body in spanner cavity and fix, make firm position, not easily misplace skidding, and moment of torsion is qualified, and structure is simple; And spanner has the arm of force, laborsaving when making to assemble, convenient, one man operation; Spanner belongs to conventional tool simultaneously, and commercially easily buy, not fragile, user is easy to use.The clamp-in valve structure that the utility model provides is simple, and easy to operate, efficiency of assembling is high, and assembly quality is stablized.

In figure: 1, mouth body, 11, mouth body rod, 12, mouth body chassis, 13, air vent, 131, spanner cavity, 2, sealed cap, 3, tightening nut, 4, seal ring, 5, wheel rim, 6, inner hexagon spanner.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Fig. 1 and Fig. 2 jointly shown in, a kind of clamp-in valve, comprise: mouth body 1, mouth body 1 is metal mouth body, mouth body 1 comprises the mouth body rod 11 and mouth body chassis 12 that are set to one, mouth body 1 is provided with air vent 13, air vent 13 runs through whole mouth body 1 from the initial end face on mouth body chassis 12, air vent 13 is provided with the spanner cavity 131 for holding spanner extended inward from the starting point face on mouth body chassis 12, spanner cavity 131 is interior prism cavity or semicircular cavities etc., when assembling, the spanner suitable with spanner cavity 131 shape can be selected, preferably, spanner cavity 131 is interior hexagonal cavity, inner hexagon spanner selected by spanner, facilitate assembling.
Mouth body rod 11 is connected with sealed cap 2 away from the one end on mouth body chassis 12, the joint of mouth body rod 11 is connected with tightening nut 3, tightening nut 3 is preferably hexagon nut, and the other end plane on mouth body chassis 12 is provided with annular groove, is provided with seal element in annular groove, seal element is preferably seal ring 4, certainly, also can select other seal elements, air vent 13 is built with valve inside (not shown), for techniques well known, do not repeat them here.
Its working principle is as follows:
As shown in Figure 3, during use, mouth body rod 11 is passed from the valve port of wheel rim 5, and make mouth body chassis 12 be positioned at the inner side of wheel rim 5, then tightening nut 3 is enclosed within mouth body rod 11, then by inner hexagon spanner 6 according to the direction in Fig. 3 shown in filled arrows, be inserted in interior hexagonal cavity and mouth body 1 fixed, then screw tightening nut 3 to make to be formed between the inwall of seal ring 4 and wheel rim 5 to seal, finally install sealed cap 2.In the process, owing to having six surface of contact between inner hexagon spanner 6 and interior hexagonal cavity, make firm position, not easily misplace skidding, and moment of torsion is qualified, and structure is simple, and inner hexagon spanner 6 has the arm of force, laborsaving when making to assemble, convenient, one man operation; Inner hexagon spanner 6 belongs to conventional tool simultaneously, and commercially easily buy, not fragile, user is easy to use.
The clamp-in valve structure that the utility model provides is simple, and easy to operate, efficiency of assembling is high, and assembly quality is stablized.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
