Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of locking mechanisms, and particularly relates to a locking mechanism capable of being fixed on a curved wall. BACKGROUND

[0002] The curved wall is a very unique and attractive design style, which is different from the traditional plane wall and has a curved and streamlined appearance. The curved wall can be used in indoor or outdoor environments, and adds artistic and dynamic feeling to the space. In outdoor design, the curved wall can be used for the design of the building facade, bringing dynamic and three-dimensional feeling to the building.

[0003] Some people install a light bar on the curved wall for the beauty of the curved wall building to decorate the building and increase the aesthetic degree. Through the collocation of different colors, brightness and light effects, various unique visual effects can be created to create a specific atmosphere and style.

[0004] However, when installing the light bar, the light bar needs to be connected and fixed with the curved wall. At present, most of the expansion bolts and hook structures are used to drill holes in the wall, then the expansion bolts are fixed in the holes, and finally the light bar is hung on the hook. Although this structure can facilitate the installation of the light bar, the expansion bolt deforms in the hole during installation, and the volume increases to complete the stable fixation in the hole. However, when the expansion bolt is disassembled, the expansion bolt cannot be smoothly taken out of the hole, and the expansion bolt structure needs to be damaged to be taken out of the drilled hole. After taking out, it cannot be used continuously, which is relatively wasteful. In addition, the hook used is fixed in size and cannot stably fix the light bar with different thicknesses, so that the use of the equipment also has certain limitations. Therefore, it is necessary to design a locking mechanism capable of being fixed on a curved wall to complete the connection and fixation of the light bar and the curved wall. SUMMARY

[0005] The purpose of the present application is to provide a locking mechanism capable of being fixed on a curved wall, which can avoid the trouble of being fixed only by the traditional expansion bolt and cannot be disassembled, facilitate the recycling of the equipment, avoid waste, and save costs.

DETAILED DESCRIPTION

[0023] In order to make the purpose and advantages of the present application more clear and explicit, the present application is specifically described below in combination with examples. It should be understood that the following text is only used to describe one or several specific embodiments of the present application, and does not strictly limit the specific protection scope of the present application.

[0024] Embodiment 1

[0025] As Figures 1-3 shown, a locking mechanism fixed on a curved wall includes a fixed plate 1, both sides of the fixed plate 1 are hinged with connecting plates 2, which facilitates the fixed plate 1 and the connecting plates 2 to be attached to the curved wall, different curved walls can be used, and a larger gap during fixing is avoided, the appearance of the fixed equipment is improved, the fixed plate 1 and the connecting plates 2 can also be used as arc-shaped plates instead of the curved wall matching, one side of the connecting plate 2 is provided with two groups of first locking assemblies fixed with the curved wall, and one side of the fixed plate 1 is provided with a second locking mechanism;

[0026] The first locking assembly includes two connecting plates 2, each with a through-tube 3 fixed on one side. A lead screw 30 is rotatably mounted on one side of the inner wall of the through-tube 3. The lead screw 30 is made of carbon steel to increase its strength and service life. Multiple moving blocks 4 are threaded at equal intervals onto the outer wall of the lead screw 30. Multiple through slots 7 are opened through the outer wall of the through-tube 3, with no fewer than three slots 7. A reinforcing block is fixed on the inner wall of the through-tube 3, located on one side of the through slot 7, and is rotatably connected to the lead screw 30 to support it and make its rotation more stable. A pressing plate 8 is slidably mounted inside the through slot 7. The extrusion plate 8 can slide up and down within the through groove 7, facilitating tight fixation against the inner wall of the mounting groove on the curved wall. A linkage plate 9 is fixed at the bottom of the extrusion plate 8 within the insertion tube 3, driving the movement of the extrusion plate 8 via the linkage plate 9. A through groove 10 is formed on the outer wall of the linkage plate 9, and a limiting block 6 is slidably installed inside the groove 10. The number of grooves 10 and limiting blocks 6 on each linkage plate 9 is the same as the number of moving blocks 4. Each end of the limiting block 6 extending outside the groove 10 is provided with a fixing ear 5, and the other side of the fixing ear 5 is fixed to the outer wall of the corresponding moving block 4, facilitating movement via the moving block 4. The movement of the screw 30 causes the limiting block 6 to move within the inclined groove 10, thus facilitating the movement of the pressing plate 8 on the linkage plate 9. This is quite practical. A rotating block 11 is fixed to one end of the screw 30 near the fixed plate 1. The rotating block 11 is rotatably connected to the inner side of the insertion pipe 3. An installation groove for the insertion pipe 3 is pre-drilled in the wall, allowing the insertion pipe 3 to be inserted into the installation groove. Then, using an external hexagonal wrench inserted into the hexagonal groove, the rotating block 11 is rotated. The rotating block 11 drives the screw 30, which in turn drives the moving block 4 to move synchronously. The moving block 4 then drives the limiting block 6 on the fixed ear 5 to move. The limiting block 6 engages with the inclined groove 10. The pressing plate 8 moves along the through groove 7 and presses the inner wall of the mounting groove, thus fixing the insertion tube 3 stably in the mounting groove. This fixes the fixing plate 1 stably on the curved wall, avoiding the trouble of using traditional expansion bolts, which can only fix but cannot be disassembled. The operation is simple and convenient. The pressing plate 8 has multiple anti-slip protrusions on the side facing the insertion tube 3, which increases the stability and firmness of the insertion tube 3. A hexagonal groove is opened on one side of the rotating block 11, which makes it easy to use an external hexagonal wrench. By inserting the wrench into the hexagonal groove, the rotating block 11 can be rotated effortlessly, which in turn drives the lead screw 30 to rotate.

[0027] The working principle of the present application is that: the installation groove matched with the inserting pipe 3 is punched in advance on the wall surface, the inserting pipe 3 is inserted into the installation groove, then the external hexagonal wrench is inserted into the hexagonal recess, the rotating block 11 is twisted and rotated, the rotating block 11 drives the screw rod 30, the screw rod 30 drives the moving block 4 to move synchronously, the moving block 4 drives the limiting block 6 on the fixed lug 5 to move, the limiting block 6 cooperates with the inclined groove 10, drives the extrusion plate 8 to move along the through groove 7, and extrudes the inner wall of the installation groove, so that the inserting pipe 3 is stably fixed in the installation groove, thereby the fixed plate 1 is stably fixed on the curved wall, and the trouble that the traditional expansion bolt can only be fixed and cannot be disassembled is avoided.
