The technical features, contents, and advantages of the present invention, as well as the advantages thereof, can be understood by the present inventors, and the present invention will be described in detail with reference to the accompanying drawings. The subject matter is only for the purpose of illustration and description. It is not intended to be a true proportion and precise configuration after the implementation of the present invention. Therefore, the scope and configuration relationship of the attached drawings should not be interpreted or limited. First described.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following, the embodiments of the present invention are described with reference to the accompanying drawings, in which the same elements in the following embodiments are denoted by the same reference numerals.

Please refer to FIG. 1 to FIG. 3 together, which are respectively a schematic diagram of a closed state, an open state diagram and an operation diagram of an embodiment of a lock function having an air pumping function.

As shown in the figure, the air lock function lock 100 of the present invention comprises a bracket 10, an air module 20, a lock bar module 30 and a locking module 40. The bracket 10 has a U-shaped structure or a horseshoe-shaped structure, and one side of the bracket 10 having no opening is disposed at one end of the inflatable module 20. One end of the inflatable module 20 is telescopically provided with a telescopic rod 21 adjacent to one end of the bracket 10, and the other end of the inflatable module 20 has an inflation hole 22. The lock bar module 30 is disposed on a side of the bracket 10 having an opening. The locking module 40 has a locking hole 40 connected to one end of the telescopic rod 21 to be located in a space surrounded by the bracket 10, and the locking module 40 is connected to the locking rod module 30.

Therefore, when the locking module 40 is in the locked state, the telescopic rod 21 cannot move relative to the inflatable module 20, and the locking bar module 30 is in a closed state; when the locking module 40 is in the unlocked state, The telescopic rod 21 is movable relative to the inflatable module 20, and when the locking module 40 is close to the inflatable module 20, the locking rod module 30 is in an open state.

Further, the inflatable module 20 includes a telescopic rod 21, an inflation hole 22, and an inflation cylinder 23. The telescopic rod 21 and the inflating hole 22 are respectively disposed at two ends of the inflating cylinder 23, and the side of the bracket 10 having no opening is disposed at the other end of the inflating module 20, for example, the bracket 10 is similar to a U-shaped structure, and The arc portion is fixed to one end of the inflator tube 23. Preferably, the bracket 10 can be made of a metal material. The specific technical means for the expansion and contraction of the telescopic rod 21 in the inflating cylinder 23 to inflate the components such as the tire by the inflation hole 22 are well known to those skilled in the art and will not be further described herein. That is to say, the lock 100 having the air pumping function of the present invention is a lock having an inflation function.

In addition, the lock bar module 30 includes two lock levers, and one end of the two lock levers is respectively pivoted at two ends of the side of the bracket 10 having the opening. Preferably, the lock bar module 30 can be made of a metal material and can be bent at an angle or a circular arc shape. Each of the two opposite frames of the bracket 10 has a sliding slot 11 . The locking module 40 has two connecting rods 42 connected between the locking module 30 and the bracket 10 . Each connecting rod 42 is slidably connected to one end of the bracket 10 . The ground is disposed in the chute 11. Therefore, when the telescopic rod 21 is telescoped and the interlocking module 40 is displaced, the lock bar module 30 can be brought into a closed state and an open state by the arrangement of the connecting rod 42 and the chute 11; wherein the closed state is The other ends of the two lock levers are in contact with each other or close together, and preferably the angle between the two connecting rods 41 and the telescopic rod 21 is equal to each other, for example, 120 degrees, as shown in FIG. 1; and the open state is two lock levers. The other end has a gap (ie, as shown in FIG. 2) that is not in contact with each other, so that in the open state, the two lock levers of the lock bar module 30 can be passed through the tire of the bicycle and then turned into a closed state. The purpose of the lock is as shown in Figure 3.

Incidentally, one end of the connecting rod 42 slidably disposed in the chute 11 and the two lock levers of the lock bar module 30 may have a rope body, such as a steel cord, to slide on the connecting rod 42 When sliding in the slot 11, the two lock levers of the drag lever module 30 are rotated. That is, the technique of interlocking between one end of the connecting rod 42 and the two lock levers of the lock bar module 30 is well known to those skilled in the art, and will not be further described herein.

Please refer to FIG. 4, which is a schematic diagram of the lock state on the embodiment of the lock head having the air pumping function of the present invention. The locking module 40 can be a circular structure. The connecting portion of the telescopic rod 21 and the two connecting rods 42 are located on the side wall of the locking module 40, and the locking holes 41 are disposed on one surface of the locking module 40. In addition, each of the sliding slots 11 of the bracket 10 has a limiting hole 12 adjacent to the locking bar module 30. One end of each connecting rod 42 is telescopically provided with a limiting post 43. Therefore, when the locking module 40 is in the locked state, the limiting post 43 is exposed outside the connecting rod 42 and embedded in the limiting hole 12, and when the locking module 40 is in the unlocked state, the limiting post 43 is not exposed to the connecting rod. 42 outside.

For example, the limiting post 43 can be a cylinder that is inserted into the connecting rod 42 with an elastic body, such as a spring, and when the user inserts the keyhole 41 by using a key to lock the locking module 40. The two bumps are pushed against the limiting post 43 by the rotation of the key, so that one end 3 of the limiting post 43 is exposed outside the connecting rod 42 and embedded in the limiting hole 12. When the user inserts the key into the keyhole 41 and the locking module 40 is in the unlocked state, the two protrusions are driven away from the limiting post 43 by the rotation of the key, and the limiting post can be achieved through the elastic body. It is reset without being exposed to the outside of the connecting rod 42 or retracted into the connecting rod 42.

It is worth mentioning that the above-mentioned locked state is merely an illustrative description and should not be limited.

The lock function of the present invention has the function of the above structure, so that the lock has an inflation function, thereby increasing the utility of the lock, and further improving the burden on the user to carry the inflatable tool and the lock at the same time. It is not easy to store.

The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of the invention are intended to be included in the scope of the appended claims.
