Technical Field

[0001] The utility model relates to the technical field of frame connectors, in particular to a connecting component for the corner of a decorative frame. Background Technique

[0002] A decorative frame refers to a frame structure used for decorating and beautifying various items or spaces. It is usually made of materials such as wood, metal, and plastic, can be of various shapes and sizes, and can be designed and decorated according to different needs. Decorative frames are usually used to display paintings, photos, or other items, so their stability needs to be maintained. To prevent the frame from deforming or loosening, connecting components for corners are often used to firmly connect the frame bars together to form a solid structure.

[0003] Most traditional decorative frame corners are connected to the frame bars by screws. However, when using the screw connection method, multiple screws are mostly required to achieve a stable connection. However, using multiple screws for fixation will leave obvious connection marks, damaging the overall beauty of the frame, and the screw connection requires external tools to be tightened one by one, resulting in a long installation time and affecting efficiency. Therefore, those skilled in the art have provided a connecting component for the corner of a decorative frame to solve the problems raised in the above background technique.

Through the mutual cooperation of the clamping structure and the mounting block, there is no need to use screws or other fixing tools. Only by inserting the mounting block into the insertion slot can the connection be completed. The operation is simple and fast. And through the mutual cooperation of the two connecting bevel gears, it ensures the synchronous movement of the two threaded rods, and then ensures that the two mounting blocks are clamped and fixed at the same time, improving the convenience of connection.

[0016] 2. The device hides the turntable in the outer wall of the corner connector through the setting of the hidden structure. When installing or disassembling the frame bar with the decorative frame corner connector, the turntable can be pulled outwards to move it out of the groove. At this time, the connecting block slides in the connecting slot of the rotating shaft. During the process of rotating the turntable, with the mutual cooperation of the connecting slot and the connecting block, the rotating shaft rotates synchronously with the turntable, and then drives the two connecting bevel gears to rotate. And after the turntable is used, the turntable will return to the groove under the action of the tension spring, hiding the turntable in the outer wall of the corner connector, avoiding the exposure of the turntable, improving the overall aesthetics of the decorative frame, and at the same time reducing the contact between the turntable and the external environment, thus reducing the wear and damage of the turntable.

Through the mutual cooperation of the clamping structure and the installation block 15, there is no need to use screws or other fixing tools. Only by inserting the installation block 15 into the insertion slot 13 can the connection be completed. The operation is simple and fast. And through the mutual cooperation of the two connecting bevel gears 18, it is ensured that the two threaded rods 4 move synchronously, and then it is ensured that the two installation blocks 15 are simultaneously clamped and fixed, improving the convenience of connection. Embodiment 2

[0032] Refer to Figures 7-9, this embodiment is based on the previous embodiment. The difference from the previous embodiment is that the hidden structure includes a rotating shaft 19, a connecting card slot 21, a limiting block 22, a tension spring 23, a turntable 24 and a connecting card block 25. The rotating shaft 19 is rotatably connected to the inner wall of the groove 20, and one end of the rotating shaft 19 penetrates into the corner connecting member 1 and is connected to one of the connecting bevel gears 18. A connecting card slot 21 is opened at the end of the rotating shaft 19 away from the connecting bevel gear 18. A connecting card block 25 is inserted into the connecting card slot 21. One end of the connecting card block 25 is fixedly connected to the turntable 24. Two limiting blocks 22 are fixedly connected to the inner part of the groove 20 and on the outer side wall of the rotating shaft 19, and a tension spring 23 is connected between the limiting block 22 and the turntable 24. The two threaded rods 4 penetrate through the fixed frame 3 at the end away from the insertion slot 13 and are fixedly connected to the connecting bevel gears 18, and the two connecting bevel gears 18 are meshed and connected.

[0033] When this embodiment is in use, when it is necessary to install or disassemble the frame bar 14 using the decorative frame corner connecting member 1, the turntable 24 can be pulled outwards to move it out of the groove 20. At this time, the connecting card block 25 slides in the connecting card slot 21 of the rotating shaft 19. During the process of rotating the turntable 24, with the mutual cooperation of the connecting card slot 21 and the connecting card block 25, the rotating shaft 19 will rotate synchronously with the turntable 24, thereby driving the two connecting bevel gears 18 to rotate. And after the turntable 24 is used, the turntable 24 will return to the inside of the groove 20 under the action of the tension spring 23, hiding the turntable 24 in the outer side wall of the corner connecting member 1, avoiding the exposure of the turntable 24, improving the overall aesthetics of the decorative frame, and at the same time reducing the contact between the turntable 24 and the external environment, thereby reducing the wear and damage of the turntable 24.
