[0001] This utility model relates to the field of construction, and in particular to a hollow, weight-reducing, high-strength retaining wall. Background Technology

[0002] A support frame is a component commonly used in fields such as construction and industrial equipment support. It mainly serves to support and fix related parts or structures, providing a stable support foundation for various devices.

[0003] In existing technologies, retaining members are usually constructed as a single piece or a simple splicing structure, and are installed and fixed by means of welding, bolting, or direct connection.

[0004] The existing technology has the following drawbacks: On the one hand, during the installation and disassembly process, it is often necessary to manually hold and position the relevant components for a long time, which is cumbersome and labor-intensive, resulting in low installation efficiency; on the other hand, when multiple sets of retaining members are connected to form a support system, the stability of the connection structure is not good, which makes it difficult to meet the needs of various scenarios with high requirements for support stability. It is prone to shaking and loosening when bearing heavy loads or being affected by external forces. Therefore, a hollow, weight-reducing, high-strength retaining member is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a hollow, weight-reducing, high-strength retaining piece, which aims to improve the problem of inconvenient operation during the assembly process in the prior art.

The positioning mechanism includes a wedge block that is slidably connected to the inner wall of the support frame, and the rear end of the wedge block is elastically connected to the support frame via a return spring.

[0007] As a further description of the above technical solution: The connecting mechanism includes a round tube, which is fixedly connected to the side wall of the fixing frame. A connecting frame is rotatably connected to the outer wall of the round tube. An adjusting screw is threadedly connected to the inner wall of the connecting frame. A mounting block is rotatably connected to the bottom end of the adjusting screw. A threaded hole is opened on the side wall of the fixing frame.

[0008] As a further description of the above technical solution: The connecting frame is provided in two sets, and the two sets of connecting frames are symmetrically arranged on both sides of the fixed frame.

[0009] As a further description of the above technical solution: The rear end of the wedge is fixedly connected to one end of the reset spring, and the other end of the reset spring is fixedly connected to the inner wall of the rear end of the support frame.

[0010] As a further description of the above technical solution: The wedge is inserted into the inner wall of the positioning hole.

[0011] As a further description of the above technical solution: Both the fixed frame and the support frame have rectangular grooves on their surfaces.

[0012] This utility model has the following beneficial effects: 1.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-3 This utility model provides an embodiment of a hollow, weight-reducing, high-strength support, including a mounting foot 1 with bolt holes for bolts to pass through and mount on the ceiling. A fixing frame 2 is fixedly connected to the bottom of the mounting foot 1. The fixing frame 2 and a support frame 4 form the entire cable support device. A guide block 3 is fixedly connected to the inner side of the fixing frame 2, allowing the support frame 4 to be inserted and move vertically. The support frame 4 is inserted into the outer wall of the guide block 3. Both the support frame 4 and the fixing frame 2 are made of high-strength steel and can withstand significant weight. A positioning mechanism is provided on the inner wall of the support frame 4, and positioning holes 7 are provided on the outer wall of the fixing frame 2. A connecting mechanism is provided on the side wall of the fixing frame 2.

[0018] The positioning mechanism includes a wedge 6, which is inclined. When the inclined surface is squeezed, the wedge 6 will move along the inner wall of the support frame 4. The wedge 6 is slidably connected to the inner wall of the support frame 4. The support frame 4 has a corresponding slot for the wedge 6, which can satisfy the back-and-forth movement of the wedge 6. The rear end of the wedge 6 is elastically connected to the support frame 4 through a return spring 5.

[0019] Reference Figures 4-5 The connecting mechanism includes a round tube 8, which is fixedly connected to the side wall of the fixed frame 2. The round tube 8 mainly supports and connects the overall connecting frame 9. The outer wall of the round tube 8 is rotatably connected to the connecting frame 9. The inner wall of the connecting frame 9 is threadedly connected to an adjusting screw 10. The inner wall of the connecting frame 9 has a matching slot for the adjusting screw 10, which allows the adjusting screw 10 to move along the inner wall of the connecting frame 9. The bottom end of the adjusting screw 10 is rotatably connected to a mounting block 11. The mounting block 11 has an opening, which allows the bolt to pass through the opening. The side wall of the fixed frame 2 has a threaded hole 12. The threaded hole 12 is mainly used to allow the bolt to pass through the opening of the mounting block 11 and connect with the threaded hole 12 after the connecting frame 9 rotates counterclockwise, ensuring the stability of the connection between the connecting frame 9 and the fixed frame 2. There are two sets of connecting frames 9, which are symmetrically arranged on both sides of the fixed frame 2.

[0020] Reference Figures 1-3The rear end of the wedge 6 is fixedly connected to one end of the return spring 5. When the wedge 6 moves backward, it will compress the return spring 5. When resetting, the return spring 5 will use its reverse elastic force to reset the wedge 6. The other end of the return spring 5 is fixedly connected to the inner wall of the rear end of the support frame 4. The wedge 6 is inserted into the inner wall of the positioning hole 7. The surfaces of the fixing frame 2 and the support frame 4 are both provided with rectangular grooves.

[0021] Working principle: First, during the use of the entire device, bolts are used to fix the entire device to the ceiling or other basic carrier by passing them through the bolt holes on the mounting feet 1. Then, the support frame 4 is inserted from bottom to top, aligned with the guide block 3 on the fixed frame 2. During insertion, the bottom end of the fixed frame 2 will press against the inclined surface of the wedge block 6. When the inclined surface is pressed, the wedge block 6 will move backward and compress the return spring 5. When the wedge block 6 and the positioning hole 7 are aligned, the reverse elastic force of the return spring 5 will carry the wedge block 6 into the slot of the positioning hole 7, which can position the entire support frame 4. The height of the support frame 4 can be adjusted according to the actual installation height. At this time, bolts can be passed through the rectangular slots on the support frame 4 and the fixed frame 2 respectively for connection and installation. The operation is simple and convenient, and the operator does not need to hold the entire support frame 4. When the support frame 4 needs to be removed, the bolt connection between the support frame 4 and the fixed frame 2 is released. Simply separate the wedge block 6 from the positioning hole 7 and move the entire support frame 4 downward from the outer wall of the guide block 3.

[0022] When multiple connections are needed to increase stability of the device, simply rotate the connecting frame 9 clockwise, so that the connecting frame 9, along with the adjusting screw 10 and the mounting block 11, rotates to a horizontally aligned state. Rotate the adjusting screw 10 to move it along the inner wall of the connecting frame 9, causing the mounting block 11 to move closer to the adjacent fixed frame 2, until the opening of the mounting block 11 is aligned with the threaded hole 12 of the fixed frame 2. Use a bolt to pass through the opening of the mounting block 11 and screw it into the threaded hole 12 to achieve a fixed connection between the two sets of fixed frames 2, ensuring the stability of the connection of multiple sets of fixed frames 2.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
