[0032] The present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model and do not limit the utility model. Additionally, it should be noted that for the convenience of description, only the parts related to the utility model are shown in the drawings.

[0033] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0034] Please refer to Figures 1 to 6, an embodiment of the present utility model provides a lock with a pressing function, including:

[0035] A lock body 1, which is axially provided with an installation hole 11 along its inner edge, and a baffle 12 is integrally arranged at its bottom end. A through hole 13 is provided on the baffle 12, and a first snap ring groove 14 is provided near the top end in the installation hole 11;

[0036] A lock core 2 is arranged in the installation hole 11. A connection groove 21 is provided at its bottom end. Symmetrically arranged on both sides of the lock core 2 are spiral grooves 22 communicating with the connection groove 21. A second snap ring groove 23 corresponding to the first snap ring groove 14 is provided on the outer periphery of the lock core 2. An inner snap ring 24 is arranged in the first snap ring groove 14 and the second snap ring groove 23;

[0037] A lock core shaft 3, whose top end passes through the through hole 13 and extends into the connection groove 21. A lock core pin 31 is vertically passed through the top end of the lock core shaft 3, and both ends of the lock core pin 31 pass through the spiral grooves 22 on the same side;

[0038] A guiding component 4 is integrally arranged on the inner wall of the installation hole 11, and is used to guide the lock core pin 31, so that the lock core shaft 3 moves a certain distance along its axial direction away from the lock body 1 and then rotates a preset angle, or rotates a preset angle and then moves a certain distance along its axial direction towards the lock body 1;

[0039] A lock tongue 5 is fixedly arranged at the bottom end of the lock core shaft 3.

[0040] In this embodiment, when the lock is in the unlocked state and to complete the locking operation, first rotate the lock core 2 with a key. The lock core 2 drives the lock core shaft 3 to rotate a preset angle through the lock core pin 31, so that the lock tongue 5 rotates to the locking position. The preset angle for locking of most locks is 90 degrees. In special cases, it can also be 60 degrees or 45 degrees, etc. At this time, continue to rotate the lock core 2. The spiral groove 22 presses the lock core pin 31. Under the action of the guiding component 4, the lock core shaft 3 no longer rotates, but contracts along its axial direction, realizing the pressing of the lock tongue 5, and the locking effect is good. Reverse rotation of the lock core 2 completes the unlocking operation.

[0041] The guiding component 4 is integrally formed in the lock body 1, replacing the original lock core sleeve, reducing the number of assembled parts, reducing the cumulative error of the lock assembly, significantly reducing the wobble amount, and improving the performance of the lock. In the lock of the present application, the inner snap ring 24 is installed in the lock core 2 and the lock body 1, avoiding the problems that the inner snap ring 24 is prone to deformation and falling off after assembly.

[0042] In a preferred embodiment, as Figure 3 and Figure 4As shown, the guiding component 4 includes an integrally arranged first stopper 41 and a second stopper 42 on the inner wall of the mounting hole 11; the first stoppers 41 are symmetrically arranged on both sides inside the mounting hole 11, and the second stoppers 42 are symmetrically arranged on the other two sides; the bottom end of the first stopper 41 is connected to the baffle 12; a first guiding groove 43 is formed between the first stopper 41 and the second stopper 42 on its clockwise side, a second guiding groove 44 is formed between the first stopper 41 and the second stopper 42 on its counterclockwise side, and a through groove 45 is arranged between the bottom ends of the first guiding groove 43 and the second guiding groove 44 on its clockwise side; both ends of the lock core pin 31 extend into the corresponding first guiding groove 43 respectively, or both ends of the lock core pin 31 extend into the corresponding second guiding groove 44 respectively.

[0043] In this embodiment, according to which side of the door body the lock is installed on, it is designed whether the lock core pin 31 is inserted into the first guiding groove 43 or the second guiding groove 44. When the lock core pin 31 is inserted into the first guiding groove 43, the lock core 2 rotates to one side to complete the pressing and locking of the lock tongue 5; when the lock core pin 31 is inserted into the second guiding groove 44, the lock core 2 rotates to the other side to complete the pressing and locking of the lock tongue 5; the applicability of the lock is improved.

[0044] When the lock is in the unlocked state, the lock core pin 31 is in the through groove 45. At this time, when the lock core 2 is rotated, under the limitation of the through groove 45, the lock core pin 31 can only rotate along the through groove 45, thereby realizing the rotation of the lock tongue 5. After the lock core pin 31 abuts against the first stopper 41, the lock tongue 5 rotates to the locking position. When the lock core 2 is continuously rotated, the spiral groove 22 squeezes the lock core pin 31 to move it along the first guiding groove 43 or the second guiding groove 44, driving the contraction of the lock core shaft 3, realizing the pressing of the lock tongue 5, and the guiding effect of the guiding component 4 is good.

[0045] In a preferred embodiment, as Figure 2 and Figure 5 shown, a sealing ring groove is formed above the outer circumference of the lock core 2 at the second retaining ring groove 23, and a sealing ring 25 is sleeved in the sealing ring groove, ensuring the sealing between the lock core 2 and the lock body 1.

[0046] In a preferred embodiment, as Figure 2 and Figure 6 shown, a spring 6 is arranged at the top end of the lock core shaft 3 in the connecting groove 21, which can play a role in earthquake resistance and improve the user's physical feeling during the operation of the lock; a limiting groove 26 is formed at the bottom of the top end of the spiral groove 22. Under the tension of the spring 6, the lock core pin 31 is stuck at the limiting groove 25, ensuring that the lock tongue 5 is in a pressed state and the earthquake resistance effect of the spring 26 in the pressed state; the depth of the limiting groove 26 is 1 / 5 - 1 / 4 of the outer diameter of the lock core pin 31, ensuring that the lock core pin 31 can smoothly disengage from the limiting groove 26 when the lock core 2 is rotated.

[0047] In a preferred embodiment, asFigure 5 As shown, positioning planes 32 are respectively arranged around the bottom end of the lock core shaft 3. Chamfers 33 are arranged between adjacent positioning planes 32. External threads are arranged on the chamfers 33. A square hole 51 is formed at one end of the lock tongue 5 corresponding to the bottom end of the lock core shaft 3. The lock tongue 5 is fixedly installed at the bottom end of the lock core shaft 3 through an upper nut 52 and a lower nut 53. Washers 54 are arranged between the upper nut 52 and the lower nut 53 and the lock tongue 5.

[0048] In this embodiment, the lock tongue 5 is positioned and assembled with the lock core shaft 3 through the square hole 51, ensuring that the lock tongue 5 accurately switches between the locked position and the unlocked position. The upper nut 52 and the lower nut 53 cooperate to clamp and fix the lock tongue 5, and the fixed position is adjustable with good fixing effect.

[0049] In some embodiments, the lock tongue 5 can select different installation and fixing methods according to requirements. For example, a support step is arranged near the bottom end of the lock core shaft 3, and the lock tongue 5 is clamped and fixed by a nut and the support step. The fixed position of the lock tongue 5 in this installation method is not adjustable, but the stability is better, and the reliability in use is high for the designed dimensional structure.
