During this process, the two locking components contact the lock cylinder under the compression of two locking springs. When the stepped portion of the lock cylinder moves to the two locking components, the locking components abut against the stepped portion. Releasing the hand at this point compresses the return spring on the lock cylinder, preventing the lock cylinder from returning to its original position. The locking end of the lock cylinder is inserted into the latch, completing the locking process. To unlock, pressing the button on the push-button assembly pushes the two connected pins to the sides, opening the two locking components. When the two locking components disengage from the stepped portion, the return spring's restoring force pushes the lock cap and lock cylinder back to their original positions, thus unlocking. Compared to existing structures, the push-button assembly and two sets of elastic components not only facilitate installation but also ensure that the symmetrical arrangement of the two sets of elastic components results in uniform lateral pressure on the lock cylinder, facilitating locking and unlocking.

[0028] Specifically, here, the elastic components 3 are in two groups, symmetrically arranged on both sides of the lock cylinder 2; each group of elastic components includes a locking member 301 and a locking spring 302; the locking spring is perpendicular to the lock cylinder; one end of the locking spring abuts against the inner wall of one side of the outer shell 1, and the other end abuts against the outer surface of the locking member 301 to press the locking member and the lock cylinder into place.

[0029] like Figure 9 As shown, the locking member 301 includes a body 301a, a rectangular groove 301b along the length of the body is provided in one of the surfaces of the body, and a fastening block 301c is provided in the rectangular groove. The surface of the fastening block includes a fastening inclined surface 3011c, a fastening vertical surface and a fastening plane. A spring post 301d perpendicular to the body is provided on the outer vertical surface of the body. The other end of the locking spring 302 is sleeved on the spring post to stably install the locking spring 302.

[0030] like Figures 6-7 As shown, a cross-shaped and interconnected transverse groove 102 and a longitudinal groove 103 are provided on the inner surface of the outer casing 1; the two ends of the transverse groove are respectively connected to the inner walls of the two sides of the outer casing, and two sets of elastic components 3 are provided in the transverse groove and are respectively located on both sides of the lock cylinder 2; one end of the longitudinal groove 103 is located in the bottom plate of the outer casing 1, and the other end is provided with a sealing plate 103a. The sealing plate is located inside the outer casing and has a lock cylinder hole for the lock cylinder 2 to pass through.

[0031] The large-diameter section 201 and the stepped section 203 are located within the longitudinal groove 103.

[0032] like Figures 1-5 As shown, a lock cap 7 is provided at the pressing end, and a return spring 8 is sleeved on the small-diameter section 202 of the lock cylinder; one end of the return spring abuts against the end face of the lock cap connected to the pressing end, and the other end is located outside the longitudinal groove 103 and abuts against the sealing plate 103a; when the lock cylinder is engaged with the latch 6 and is in the locked state, the return spring is compressed; one end of the outer shell 1 is provided with a cylindrical body 9 integrally formed therewith, and the cylindrical body communicates with the internal space of the outer shell; the lock cap 7 is cylindrical and movably inserted into the cylindrical body; when the lock cylinder 2 is engaged with the latch 6 and is in the locked state, the return spring is compressed. Threads are provided on the outer wall of the pressing end of the lock cylinder, and the lock cap and the lock cylinder are fixedly connected by the threads. The cylindrical body here can accommodate the lock cap 7 in the locked (locked) state.

[0033] like Figure 8As shown, the back plate of the outer casing 1, opposite to the faceplate 5, is provided with a through hole 101 communicating with the internal space of the outer casing; the button assembly 4 includes a button 401, two insertion posts 402 with one end perpendicular to the inner surface of the button and fixedly connected, a locking hook 403 provided at the front end of each insertion post, and an insertion groove 404 provided in each insertion post; the insertion groove includes an insertion inclined surface 404a, an insertion vertical surface 404b, and an insertion flat surface 404c; the locking hook is inserted into the outer casing 1 through the through hole 101 and combined with the elastic component 3. Specifically, the elastic component 3 is equipped with a latching block 301c for engaging with the lock hook 403, which can prevent the button component 4 from dislodging. To unlock the lock cylinder and reset it, the button 401 is pressed, which pushes the two insertion pins 402 further into the outer casing 1. At this time, the insertion inclined surface 404a contacts the latching inclined surface 3011c. As the latching inclined surface 3011c moves, the two locking pieces 301 can be gradually pushed open, thereby unlocking the lock.

[0034] The inner surface of the cover 5 is provided with a transverse guide groove 501 that is combined with the transverse groove 102; on one side of the transverse guide groove 501, there are two support plates 502 with one end perpendicular to the inner surface of the cover and fixedly connected, the two support plates 502 are spaced apart and the other end of the two are provided with an arc-shaped groove 502a, the arc-shaped groove is in contact with the lock cylinder.

[0035] The latch 6 is perpendicular to the lock cylinder 2. The latch has several locking notches 601 for engaging with the locking end. These locking notches are arranged in a straight line to adjust the size of the opening space of the sliding door and sliding window.

[0036] With the lock in the open state as the initial state, the lock cap 7 is located outside the cylindrical body 9. In this state, when locking is required, the lock cap 7 is pressed down, and the lock cylinder 2 moves along the outer shell 1. The return spring 8 is compressed. At this time, the two locking parts 301 are pressed against the outer wall of the large diameter section 201 of the lock cylinder by the two locking springs 302, without affecting the movement of the lock cylinder 2 relative to the outer shell. When the locking end of the lock cylinder is inserted into one of the locking notches 601 of the latch 6 and reaches the final position, the step 203 moves to the two locking parts 301, and the ends of the two locking parts that are in contact with the lock cylinder are engaged at the step. Under the action of the two locking springs 302, the two locking parts are locked into the step 203. Although the return spring 8 has a tendency to return at this time... The spring force is applied, but it cannot disengage the lock cylinder 2 from the two locking parts 301 and reset it, thus completing the locking (locking) of the lock. When unlocking is required in the locked state, the button 401 pushes the two plug pins 402 further into the outer shell 1. At this time, the plug inclined surface 404a contacts the latching inclined surface 3011c. As the latching inclined surface 3011c moves, the two locking parts 301 can be gradually pushed open. When the two locking parts disengage from the step, the lock cylinder returns to its original position under the action of the return spring 8, and the lock is opened, thus achieving unlocking. Compared with the existing structure, the structure of the button assembly 4 and two sets of elastic components 3 is not only easy to install, but also the two sets of elastic components 3 are symmetrically arranged, and the lateral pressure on the lock cylinder is uniform, which facilitates locking and unlocking.
