After the adjustment is completed, tighten the locking handle 300 to connect the locking handle 300 with the lock tongue 200, so that the lock tongue 200 is fixed. This design greatly improves the flexibility of the lock tongue 200, making it very convenient for users to adjust.
[0034] Please refer to Figure 4 In a possible implementation, the locking handle 300 includes a locking portion 301 and a handle portion 302. The handle portion 302 is disposed at one end of the locking portion 301. The outer surface of the locking portion 301 is provided with a thread, and the locking portion 301 is threadedly connected to the lock seat 100. It is easy to understand that the setting of the handle portion 302 can facilitate the user to apply force, so that the user can more easily rotate the locking handle 300, the locking portion 301 extends into the screw hole to connect with the lock seat 100, and the end of the locking portion 301 extends into the slide slot 101 to contact the lock tongue 200, so as to fix the lock tongue 200.
[0035] Please refer to Figure 4In a possible implementation, a limiting protrusion 303 is provided at the other end of the locking portion 301, and a limiting groove 201 is provided on one side wall of the lock tongue 200, and the limiting protrusion 303 extends into the limiting groove 201.

[0036] Please refer to Figure 2 In a possible implementation, an elastic member 304 is sleeved on the locking portion 301, one end of the elastic member 304 abuts against the handle portion 302, and the other end of the elastic member 304 abuts against the lock base 100. It is easy to understand that the elastic member 304 is a spring, and the side wall of the lock base 100 has an annular groove, which is arranged around the screw hole to provide a placement basis for the elastic member 304. The arrangement of the elastic member 304 can play a buffering role on the locking handle 300, which is conducive to improving the stability of the movement of the locking handle 300.
[0037] Please refer to Figure 2 In a possible implementation, a blind hole 102 is provided on the inner side wall of the slide groove 101, an elastic positioning member 103 is provided in the blind hole 102, and a first positioning groove 202 is provided on the other side wall of the lock tongue 200, and the elastic positioning member 103 extends into the first positioning groove 202. It is easy to understand that the blind hole 102 is provided to provide a mounting base for the elastic positioning member 103, and there are multiple first positioning grooves 202, and the multiple first positioning grooves 202 are evenly spaced along the side wall surface of the lock tongue 200. Each first positioning groove 202 is provided in a one-to-one correspondence with each limiting groove 201, and each first positioning groove 202 corresponds to an adjustment gear, so that each adjustment gear can be positioned. When the user pushes the lock tongue 200 to slide, the elastic positioning member 103 can achieve one positioning each time it passes through a first positioning groove 202, which provides great convenience for the user's adjustment work. In addition, the elastic positioning member 103 is composed of a spring and a ball. Under the action of the spring, the ball always contacts the side wall of the lock tongue 200. When passing through the first positioning groove 202, the ball will enter the first positioning groove 202, thereby causing the sliding of the lock tongue 200 to be stuck, so as to play a positioning role. When the user continues to push the lock tongue 200 with force, the ball can slide out of the first positioning groove 202 and then enter the next first positioning groove 202. The setting of the ball can reduce the friction between the elastic positioning member 103 and the lock tongue 200, which is beneficial to improve the sliding smoothness of the lock tongue 200.
[0038] Please refer to Figure 2 and Figure 6In a possible implementation, the lock base 100 includes a base 104 and a top cover 105, and the base 104 and the top cover 105 are detachably connected. It should be noted that the base 104 and the top cover 105 are connected by bolts. When the arc lock needs to be maintained, it is only necessary to unscrew the bolts, which is very convenient. In addition, a positioning protrusion 106 is provided on the top cover 105, and a second positioning groove 107 is provided on the base 104. When the top cover 105 is installed, the positioning protrusion 106 extends into the second positioning groove 107, which plays a role in positioning and preliminarily fixing the top cover 105, so as to facilitate the subsequent installation work of the staff.
[0039] Please refer to Figure 2 In a possible implementation, a push handle 203 is provided on the lock tongue 200, and a long hole 108 is provided on the top cover 105. The long hole 108 is connected to the slide slot 101, and the long hole 108 extends along the sliding direction of the lock tongue 200, and the push handle 203 extends from the long hole 108. It is easy to understand that the setting of the push handle 203 can facilitate the user to apply force, so that the user can push the lock tongue 200 more easily. The push handle 203 is fixed on the top surface of the lock tongue 200 by bolts. The setting of the long hole 108 can not only play a evasive role for the push handle 203, so that the push handle 203 extends out of the slide slot 101, but also play a restrictive role on the lock tongue 200, preventing the lock tongue 200 from sliding out of the slide slot 101.
[0040] Please refer to Figure 2 In a possible implementation, the top surface of the top cover 105 is provided with a scale mark, and the scale mark is arranged along the length direction of the long hole 108.

The sliding portion 204 is arc-shaped and extends into the slide slot 101. The connecting portion 205 is used to connect to an external component. It is easy to understand that the sliding portion 204 and the slide slot 101 are both arc-shaped. After the sliding portion 204 extends into the slide slot 101, it is fixed to the lock base 100 under the action of the locking handle 300. The connecting portion 205 is used to connect to the display unit box.
[0042] Please refer to Figure 3In a possible implementation, the connection portion 205 is provided with a connection hole 206 and an adjustment slot 207, and an adjustment plate 208 is slidably arranged in the adjustment slot 207, and the adjustment plate 208 is used to adjust the size of the connection hole 206. It should be noted that the adjustment plate 208 has a through hole corresponding to the connection hole 206. When the user slides the adjustment plate 208, the through hole on the adjustment plate 208 will be misaligned with the connection hole 206 to achieve the effect of adjusting the size of the connection hole 206, thereby changing the size of the parts that can pass through the connection hole 206, which is conducive to improving the versatility of the arc lock. In addition, the connection portion 205 is also provided with a limit plate 209, which is located at the opening of the adjustment slot 207. When the adjustment plate 208 moves to the extreme position, the adjustment plate 208 conflicts with the limit plate 209. The setting of the limit plate 209 can prevent the adjustment plate 208 from sliding out of the adjustment slot 207, which is conducive to improving the overall structural stability of the lock tongue 200.
