All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In order to solve the above problems, the present utility model proposes a manual tightening assembly mechanism for a valve, as shown in fig. 1 to 4, comprising: a clamp assembly 10 and a handle assembly 20.

Wherein the clamp assembly 10 has two clamping portions 12 hinged to each other, the two clamping portions 12 being adapted to clamp the valve stem 30. The clamp assembly 10 is shown in fig. 3 after gripping the valve tip 30.

A handle assembly 20 is connected to the clamp assembly 10. After the clamp assembly 10 clamps the valve opening 30, if the clamp assembly 10 is directly pulled to the predetermined installation position of the hub 40, the clamp assembly 10 is easy to open and is not easy to operate, and the pulling force is not easy to apply, so that the valve opening 30 can be pulled to the installation position just by pulling the handle assembly 20.

To ensure a good pulling effect, the clamp assembly 10 should maintain the valve 30 in a clamped condition during pulling.

The clamp assembly 10 in this embodiment comprises two clamp units, each clamp unit comprises a clamping rod 11, a clamping part 12 arranged at one end of the clamping rod 11, and a finger ring 13 arranged at the other end of the clamping rod 11; the clamping bars 11 of the two clamping monomers are hinged and connected with the handle assembly 20. The two clamp monomers are mirror image structures, and the structures of the two clamp monomers are the same or similar.

The clamping rods 11 of the two clamping monomers are hinged to form an X-shaped clamping structure. When the two clamp monomers are folded, namely in the state of clamping the inflating valve 30, the Y-shaped structure is formed. When the two clamp units are opened, i.e. the two clamping parts 12 release the clamped inflating valve 30, the X-shaped structure is formed.

The clamp assembly 10 comprises a pin shaft 14, first pin holes are respectively formed in two clamping rods 11 of the clamp monomers, a second pin hole is formed in the handle assembly 20, and the pin shaft 14 sequentially penetrates through the first pin hole and the second pin hole to connect the clamp assembly 10 and the handle assembly 20.

In other words, the middle portions of the clamping bars 11 of the two clamping units of the clamp assembly 10 of the present embodiment are respectively provided with a first pin hole, the two clamping bars 11 intersect at the middle portion, the intersection point is the center of the first pin hole, and the intersection point is located at the second pin hole of the handle assembly 20, so that after the pin shaft 14 passes through the first pin hole and the second pin hole, the two clamping bars 11 can be connected with the handle assembly 20. Anti-drop caps may be provided at both ends of the pin 14 to prevent the two clamping bars 11 hinged to the handle assembly 20 from falling off.

It should be noted that the finger ring 13 provided on the clamping rod 11 of each clamping unit may be one or more.

The clamp assembly 10 further comprises two sets of tension springs 15, and the clamping bar 11 of each clamp unit is connected with the handle assembly 20 through one set of tension springs 15. The tension spring 15 is in a lacing wire state in a natural state, namely when the clamp assembly 10 is not acted by external force, the two clamping parts 12 are in a closed state, when the two clamping parts 12 are required to be separated, the pulling force of the tension spring 15 is required to be overcome for working, further, after the two clamping parts 12 clamp the valve mouth 30, the clamping state of the clamping parts 12 to the valve mouth 30 is not required to be maintained by fingers, the clamping of the clamping parts 12 to the valve mouth 30 can be realized by the pulling force of the tension spring 15, and therefore, when the valve mouth 30 is lifted to an assembling position, the operation is easier and more convenient.

As shown in fig. 1, the tension spring 15 is in an inclined state, the clamping rod 11 and the handle assembly 20 are respectively provided with a notch, two ends of the tension spring 15 are respectively placed in the notches, and the tension spring 15 is fixed in a welding manner or is mounted in a bolt or pin connection manner.

In some embodiments, more tension springs 15 may be provided. One tension spring 15 is provided on each clamping bar 11 in this embodiment, and in some embodiments, two or more tension springs 15 may be provided on each clamping bar 11.

As shown in fig. 3 and 4, the clamping portions 12 of the two clamping monomers are arranged right opposite, and the tail ends of the clamping portions 12 are provided with hook portions 16. The clamping portion 12 is a portion of the clamping bar 11 located below the pin 14. The tail end of the part, namely the end of the clamping rod 11 far away from the pin shaft 14, and the hook part 16 arranged at the tail end of the clamping part 12 is used for hooking in the groove of the valve nozzle 30 so as to facilitate the lifting of the valve nozzle 30.

As shown in fig. 3 and 4, opposite end surfaces of the clamping portions 12 of the two clamping units are provided with concave grooves 17, and the concave grooves 17 extend to the hook portions 16 of the clamping portions 12. The recess 17 is used for accommodating a part of the structure of the clamped valve 30, and provides an accommodating space for the valve cap of the valve 30. The opposite end surfaces of the clamping bar 11 are provided with recess grooves 17, the recess grooves 17 extending to, but not communicating with, the ends of the clamping bar 11, so that the ends of the clamping bar 11 form the above-mentioned hook portions 16.

As shown in fig. 5, opposite end surfaces of the clamping portions 12 of the two clamping monomers are concave cambered surfaces. Because the outer contour surface of the inflating valve 30 is an arc surface, the opposite end surface of the clamping part 12 is correspondingly arranged to be a concave arc surface, the inflating valve 30 can be better attached, and the clamping and lifting operations of the inflating valve 30 are facilitated.

The opposite end surfaces of the clamping part 12 are concave cambered surfaces, namely the bottom of the concave groove 17 is a concave cambered surface.

As shown in fig. 1-3, the handle assembly 20 includes a cross bar 21 and a vertical bar 22 that are connected, the vertical bar 22 being connected to the clamp assembly 10. The cross bar 21 and the vertical bar 22 are welded and fixed, the top end of the vertical bar 22 is welded with the middle part of the cross bar 21, the bottom end of the vertical bar 22, namely, the end of the vertical bar 22 far away from the cross bar 21, is provided with an opening 23, and the two clamping bars 11 of the clamp monomers are hinged in the opening 23.

It will be appreciated that the opening 23 provided at the bottom end of the vertical rod 22 is provided with the second pin hole mentioned above, and the first pin hole of the clamping rod 11 is located in the opening 23, so that the pin 14 passes through the bottom end of the vertical rod 22 when passing through the first pin hole and the second pin hole. The axis direction of the pin 14 is perpendicular to the opening direction of the opening 23.

As shown in fig. 6, the valve stem 30 is inserted upward into the fitting hole from below the fitting hole of the automobile hub 40, so that the valve cap at the upper end of the valve stem 30 passes through the fitting hole to the upper end of the hub 40. The finger of the user inserts the finger ring 13, opens two clamping bars 11, clamps the clamping part 12 at the lower end of the clamping bar 11 on two sides of the valve cap, loosens the finger on the finger ring 13, resets the clamping bar 11 under the action of the tension spring 15, and the clamping part 12 clamps the valve cap. The handle assembly 20 is lifted upward by holding the cross bar 21 again, and the valve tip 30 clamped by the clamp assembly 10 is lifted together with the clamp assembly 10 connected to the handle assembly 20, so that the valve tip 30 is mounted in the mounting hole of the hub 40.

According to the utility model, the two clamping parts 12 of the clamp assembly 10 clamp the inflating valve 30, and the handle assembly 20 connected with the clamp assembly 10 is used for integrally lifting the clamp assembly 10 clamping the inflating valve 30 to the assembly position of the automobile hub 40, so that the inflating valve 30 is quickly installed, the installation step of the inflating valve 30 is optimized, the production efficiency is improved, the product quality is effectively ensured, and the production and repair cost is reduced.
