[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example 1:

[0030] A type of lock, such as Figures 1-7 As shown, it includes a housing 1, a lock sleeve 2, an inner core 3, and a key 4. The lock sleeve 2 is disposed inside the housing 1, and the inner core 3 is rotatably disposed inside the lock sleeve 2.

[0031] A locking tongue 5 is slidably disposed inside the outer casing 1, and the outer casing 1 has a sliding groove 28 that slides with the locking tongue 5. The sliding groove 28 is adapted to the locking tongue 5.

[0032] The locking tongue 5 is used to cooperate with the limiting groove 29 on the valve stem to limit the valve stem circumferentially. Specifically, the limiting groove 29 on the valve stem is adapted to the end of the locking tongue 5. When the end of the locking tongue 5 is inserted into the limiting groove 29 on the valve stem, the valve stem is restricted by the locking tongue 5 and the valve stem cannot rotate or move.

[0033] The inner core 3 has an unlocking groove 6 for inserting the key 4, and the lock sleeve 2 has a clearance hole 22. The clearance hole 22 corresponds to the unlocking groove 6 and is used to avoid the key 4.

[0034] When the key 4 is inserted into the unlocking slot 6, rotating the key 4 can drive the inner core 3 to rotate relative to the lock sleeve 2 and make the lock tongue 5 slide, and the lock tongue 5 can extend from the lock sleeve 2 by sliding and insert into the limiting slot 29 on the valve rod or disengage from the limiting slot 29 on the valve rod and retract into the shell 1. It should be noted that the lock tongue 5 extends from the lock sleeve 2 by sliding and inserts into the limiting slot 29 on the valve rod, and the lock tongue 5 cooperates with the limiting slot 29 to limit the valve rod. At this time, the valve rod cannot be operated at will in the locked state. Conversely, the lock tongue 5 disengages from the limiting slot 29 on the valve rod by sliding and retracts into the shell 1. After the valve rod loses the limitation of the lock tongue 5, the user can normally rotate the valve rod. The user only needs to perform a simple rotation action to lock or unlock, which is simple to operate and convenient for users to use, and can effectively improve the user's experience.

[0035] The key 4 has a linkage part 25 which is matched with the avoiding hole 22 and the unlocking slot 6. The avoiding hole 22 and the unlocking slot 6 both position the linkage part 25 circumferentially. The key 4 has a reducing diameter to form an avoiding part 26. When the linkage part 25 is located in the unlocking slot 6, the avoiding part 26 is located in the avoiding hole 22. That is, when the key 4 is rotated, the linkage part 25 cooperates with the unlocking slot 6 to drive the inner core 3 to rotate, and the avoiding part 26 formed by the reducing diameter of the key 4 will not contact the inner side wall of the avoiding hole 22, which not only ensures the normal rotation of the key 4, but also avoids that the key 4 drives the lock sleeve 2 to rotate when the key 4 is rotated.

[0036] The avoiding hole 22 has a limiting part 27. When the key 4 drives the inner core 3 to rotate relative to the lock sleeve 2, the linkage part 25 is misaligned with the avoiding hole 22, and the limiting part 27 positions the linkage part 25 along the length direction of the linkage part 25. After the key 4 drives the inner core 3 to rotate relative to the lock sleeve 2, the linkage part 25 is misaligned with the avoiding hole 22, and the limiting part 27 positions the linkage part 25 along the length direction of the linkage part 25. At this time, when the operator pulls out the key 4 along the length direction of the linkage part 25, the linkage part 25 will be in contact with the limiting part 27, thereby limiting the key 4 from disengaging from the unlocking slot 6 and the avoiding hole 22.

[0037] It should be noted that how to realize the rotation of the inner core 3 relative to the lock sleeve 2 and the sliding of the lock tongue 5. In this embodiment, the bottom of the inner core 3 is eccentrically provided with a cylindrical linkage protrusion 7, and the side wall of the lock tongue 5 is provided with a fitting groove 8. The linkage protrusion 7 is inserted into the fitting groove 8. When the inner core 3 rotates clockwise or counterclockwise, the side wall of the linkage protrusion 7 contacts the side wall of the fitting groove 8 to generate a pushing force, thereby making the lock tongue 5 slide along the sliding groove 28.

[0038] The unlocking slot 6 is provided with a supporting spring 23, the unlocking slot 6 is movably provided with a ball blocking piece 24, the end of the supporting spring 23 abuts against or is connected with the ball blocking piece 24, the ball blocking piece 24 can block the avoiding hole 22, so that foreign matters outside the unlocking slot 6 cannot enter the unlocking slot 6 through the avoiding hole 22, and the elastic force of the supporting spring 23 on the ball blocking piece 24 can effectively ensure that the ball blocking piece 24 effectively blocks the avoiding hole 22, and it should be noted that the limiting portion 27 abuts against the ball blocking piece 24, so as to limit the ball blocking piece 24 from being separated from the avoiding hole 22, and in the state that the linkage portion 25 is located opposite to the avoiding hole 22, the ball blocking piece 24 abuts against the bottom of the linkage portion 25, at this time, the elastic force of the supporting spring 23 acts on the key 4 through the ball blocking piece 24, thereby ensuring the stability of the key 4 in the current state.

[0039] The inner side wall of the shell 1 is provided with a positioning groove one 9, the outer side wall of the inner core 3 is provided with a positioning groove two 10, and the side wall of the lock sleeve 2 is provided with a positioning hole 11; the positioning groove one 9, the positioning groove two 10 and the positioning hole 11 are coaxially arranged; the positioning groove one 9 is provided with a reset spring one 12; the positioning groove two 10 is slidably provided with a magnetic block one 13; the end of the reset spring one 12 abuts against or is connected with the magnetic block one 13; the magnetic block one 13 is slidably matched with the positioning groove one 9 and the positioning hole 11; the key 4 is provided with a magnetic block two 14 which is magnetically repulsive with the magnetic block one 13; the magnetic block two 14 can push the magnetic block one 13 to slide, so that the magnetic block one 13 is separated from the positioning groove two 10 and presses the reset spring one 12 into the positioning groove one 9.

[0040] It should be noted that when the key 4 is inserted into the unlocking slot 6, the magnetic block two 14 on the key 4 is opposite to the magnetic block one 13, the repulsive force of the two pushes the magnetic block one 13 to slide, so that the magnetic block one 13 is separated from the positioning groove two 10 and presses the reset spring one 12 into the positioning groove one 9, at this time, the inner core 3 can be rotated alone, and the shell 1 and the lock sleeve 2 are relatively fixed by the magnetic block one 13, so as to avoid that the inner core 3 drives the lock sleeve 2 to rotate due to friction when rotating, and conversely, when the key 4 is not inserted into the unlocking slot 6, the magnetic block one 13 is pressed into the positioning groove two 10 by the elastic force of the reset spring one 12, and the other end of the magnetic block one 13 passes through the positioning hole 11, at this time, the lock sleeve 2 and the inner core 3 are relatively fixed by the magnetic block one 13.

[0041] The outer side wall of the inner core 3 is provided with a limiting protrusion 15, and the side wall of the lock sleeve 2 is provided with a limiting hole 16 which is arranged along the circumference of the lock sleeve 2; the limiting protrusion 15 passes through the limiting hole 16; the limiting hole 16 limits the limiting protrusion 15, thereby limiting the circumferential rotation angle of the inner core 3, facilitating the user to control, and further improving the user experience.
