The specific embodiment
See also Fig. 2 to Fig. 5, the utility model Tire valve installation Tool comprises handle 2 and valve cover 1.
Valve cover 1 comprises three drag-lines 3, three elastic card claws 4 and fasteners 5.One end of handle 2 is captiveed joint with an end of three drag-lines 3 respectively, and the other end of every drag-line 3 is fixedly connected with 4, three elastic card claws 4 of an elastic card claw and distributes ringwise.The profile that the outer wall 41 of three elastic card claws surrounds is circular cone shape, and the radial dimension of itself and drag-line 3 coupling ends is less.The inner chamber that the inwall 42 of three elastic card claws surrounds is cylindric.Certainly, the profile that surrounds of the outer wall 41 of three elastic card claws also can be to be frustum of a pyramid shape.
Fastener 5 adopts round barrel shape, and the diapire 51 of fastener 5 is provided with the through hole 52 that can supply drag-line 3 to run through; Fastener 5 oral areas are set in away from handle 2 ground on the outer wall 41 of three elastic card claws, and the radial dimension of fastener 5 inwalls is between the minimum and maximum radial dimension of the frustum of a cone that the outer wall 41 of three elastic card claws surrounds.When the inner chamber that surrounds at three elastic card claw inwalls 42 is in the state of movable cutting ferrule tire tube valve, form certain space between the inwall of fastener 5 and the outer wall of elastic card claw 41, three elastic card claws 4 can open to the axis direction away from fastener 5 respectively, make the radial dimension of the radial dimension of the cylindric inner chamber that the inwall 42 of three elastic card claws surrounds greater than tire tube valve aerating section, this is convenient to elastic card claw 4 active card are enclosed within on the tire tube valve aerating section.Fastener 5 is moved to the direction away from drag-line 3, space between the outer wall 41 of the inwall of fastener 5 and elastic card claw is dwindled gradually, the pressure that three elastic card claws 4 are subjected to fastener 5 inwalls is drawn close to the axis direction, and clamp-on in the fastener 5, the radial dimension of the inner chamber that the inwall 42 of three claws forms also dwindles gradually; Along with elastic card claw 4 gos deep in the fastener 5, elastic card claw 4 produces elastic deformation, the pressure of 5 pairs of elastic card claws 4 of fastener increases, the inwall 42 of three claws and the pressure of tire tube valve aerating section are also along with increase, until this pressure greatly to only tire tube valve being drawn in and block in the mounting hole at tire tube valve, at this moment, fastener 5 inner chamber that the inwall 42 of three elastic card claws is surrounded is in the state of fixing tire tube valve.Fastener 5 is not limited only to this structure of round barrel shape, can also be tubular structures such as sleeve-like, conical ring shape, the enough big pressure of generation between the aerating section of the inwall 42 that makes elastic card claw to three elastic card claws 4 and tire tube valve as long as fastener 5 can pressurize; In addition, except tubular structure, fastener 5 can also adopt the structure of common zipper tape.
For after installing tire tube valve, be convenient to elastic card claw 4 and reset, be arranged with retracing spring 6 on the drag-line 3, an end of retracing spring 6 is replaced at the position of elastic card claw 4 near drag-line 3, and the diapire 51 of the other end of retracing spring 6 and fastener 5 offsets.The effect that retracing spring 6 is set is: at fastener 5 quick fixing tire tube valves, and be that fulcrum presses down handle 2 with the wheel hub, in the process that tire tube valve is in place, the retracing springs 6 that are arranged in the fastener 5 are compressed, and have had certain elastic potential energy; After installation, stop to fastener 5 application of forces, the elastic potential energy that retracing spring 6 has is released, overcome the friction force between the outer wall 41 of fastener 5 inwalls and elastic card claw, three elastic card claws 4 are ejected from fastener 5, the elastic card claw 4 that is ejected fastener 5 loses the constraint of fastener 5 and opens thereupon, and the pressure disappearance between elastic card claw inwall 42 and the tire tube valve aerating section can be unloaded elastic card claw 4 down apace from the aerating section of tire tube valve simultaneously.Can improve the efficient of dismantling when using the utility model like this, and then improve and used service efficiency of the present utility model.
As another embodiment of the present utility model, the inwall of elastic card claw adopts elastomeric material, and the outer wall of elastic card claw adopts rigid material; Can also do further improvement on this basis: reduce the roughness of the outer wall of rigid material, can reduce the friction force between the outer wall of fastener inwall and elastic card claw like this, help retracing spring and apace elastic card claw is ejected from fastener.
Another embodiment of the present utility model, the inwall of elastic card claw adopts rigid material, and the outer wall of elastic card claw adopts elastomeric material; At the aerating section is the tire tube valve of screw rod, can also further improve on this basis: offer the screw thread that can be complementary at the inwall of elastic card claw with the screw rod on the tire tube valve, when three elastic card claws were in the state of fixing tire tube valve, the screw thread on three elastic card claw inwalls can surround the tapped bore that cooperates with screw rod on the tire tube valve.This scheme also can improve the installation effectiveness that auto-tire valve is installed compared to prior art.
In addition, elastic card claw 4 quantity are not limited to three in the above embodiment, can also be two, four or more a plurality of.The quantity of drag-line 3 quantity with elastic card claw 4 in the above-described embodiment is consistent, elastic card claw 4 of every drag-line 3 captive joints; Certainly the quantity of drag-line 3 also can be inconsistent with the quantity of elastic card claw 4, and for example, a plurality of elastic card claws 4 are all captiveed joint with a drag-line 3.
Use the step of the utility model installation tire valve as follows:
1. the aerating section of tire tube valve is passed the valve mounting hole on the wheel hub;
2. three elastic card claws 4 directly are fastened on the tire tube valve aerating section;
3. the elastic force that hand-held fastener 5 overcomes retracing spring 6 moves down, and the space between the outer wall 41 of the inwall of fastener 5 and elastic card claw is dwindled gradually; Continue to press down fastener 5, three elastic card claws 4 are drawn close to the axis of fastener 5 direction, and clamp-on in the fastener 5, the radial dimension of the inner chamber that the inwall 42 of three elastic card claws 4 forms also dwindles gradually, until the aerating section of the inwall 42 fixing tire tube valves of three elastic card claws 4;
4. with the wheel hub be fulcrum to pressing down handle 2, tire tube valve drawn in and block only in the mounting hole of tire tube valve;
5. stop to handle 2 application of forces, and loosening fasteners 5, the elastic potential energy of retracing spring 6 discharges, three elastic card claws 4 are ejected from fastener 5, the elastic card claw 4 that is ejected fastener 5 loses the constraint of fastener 5 and opens thereupon, pressure between elastic card claw inwall 42 and the tire tube valve aerating section disappears simultaneously, can apace elastic card claw 4 be unloaded down from tire tube valve aerating section.
