[0015] Preferably, there are two fixing columns, which are symmetrically distributed on both sides of the bottom surface of the beam.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The invention achieves the effects of convenient installation and accurate positioning by arranging the cooperation of structures such as the limit mechanism. The two fixing posts are respectively inserted into the two ends of the cross beam, the limit rod is inserted into the limit hole of the fixing post, the limit rod passes through the cross beam and the fixing post, and the pushing rod inside the limit rod is pushed so that the stretching rods on both sides of the pushing rod move to the positions corresponding to the straight grooves.

Thereafter, the push rod is loosened, the return spring and the buffer rod release the pressure, and the limit rod is pulled in the opposite direction so that the stretching rod contacts the cross beam to form a stable triangle. Finally, the fixing cap on the limit rod is tightened, so that the cross beam and the fixing post can be fixed.

[0019] The present invention plays an effective role in buffering and shock absorption through the setting of the buffer mechanism. When the component is subjected to external force, the external force will be transmitted to the rotating rod and the oblique rod through the load-bearing plate. The rotating rod and the oblique rod will move around the connection point with the first moving block, so that the first moving block and the second moving block slide in the first moving groove and the second moving groove, and compress the first spring and the second spring. The first spring and the second spring will produce elastic deformation when compressed, and the external force will be converted into elastic potential energy and stored. When the external force disappears, the elastic potential energy of the spring will be released, so that the first moving block and the second moving block will return to their initial positions, thereby playing a role in buffering and shock absorption, reducing the damage to the component by the external force, effectively buffering and absorbing the impact of the external force, greatly reducing the direct effect of the external force on the component, significantly reducing the possibility of cracks, breakage and other damages to the component due to the impact of the external force, and improving the impact resistance of the component.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The limiting mechanism 2 includes a limiting rod 21, a pushing rod 22, a stretching rod 23, a return spring 24 and a buffer rod 25. The pushing rod 22 is located inside the limiting rod 21, the stretching rod 23 is hinged to both sides of one end of the pushing rod 22 through a hinge, and the return spring 24 is sleeved on the outside of the buffer rod 25.

[0030] The buffer mechanism 3 includes a rotating rod 31, a first moving block 32, an inclined rod 33 and a second moving block 34. One end of the rotating rod 31 and the inclined rod 33 are respectively rotatably connected to one end of the first moving block 32, and the other end of the inclined rod 33 is rotatably connected to one end of the second moving block 34.

[0031] The above scheme is adopted: the limit rod 21 is used as the main limit component, which cooperates with the limit hole of the fixing column 4 to limit the displacement of the component and ensure the accurate installation position of the component. The pushing rod 22 is movable inside the limit rod 21, providing power for the stretching rod 23 so that it can stretch and get stuck in the fixing column 4 at the right time to enhance the limit effect. The stretching rod 23 is connected to the pushing rod 22 by a hinge, and can be extended and contracted under the action of the compression spring 27. After being inserted into the fixing column 4, the movement of the limit rod 21 is further limited to improve the reliability of the limit. The reset spring 24 is sleeved on the outside of the buffer rod 25, one end of which is connected to the pushing rod 22 and the other end is connected to the limit rod 21. When disassembly or adjustment is required, a reset force is provided for the pushing rod 22 and the stretching rod 23 to restore them to their initial positions. By setting the cooperation of structures such as the limit mechanism 2, the effect of convenient installation and accurate positioning is achieved. The two fixing columns 4 are respectively inserted into the two ends of the beam 1, and the limit rod 21 is inserted into the limit of the fixing column 4. The stretching rod 23 is extended under the action of the compression spring 27 and contacts with the beam 1 to form a stable triangle structure. The triangle has stability, which greatly enhances the connection strength between the beam 1 and the fixed column 4, so that the entire component can withstand greater external forces during use, is not prone to loosening or displacement, and ensures the safety of the structure.

[0032] like Figures 1 to 6 As shown, cylindrical holes are provided inside both ends of the beam 1, and the cylindrical holes are used to install the limit rod 21, and the first moving groove and the second moving groove are provided on both sides of the inner bottom wall and the two sides of the inside of the beam 1 respectively, the first moving groove is used to assist the first moving block 32 to move, and the second moving groove is used to assist the second moving block 34 to move, and the bottom of both ends of the beam 1 is installed with a fixing column 4, and the fixing column 4 is provided with a limiting hole matched with the limit rod 21, and the top of the beam 1 is installed with a load-bearing plate 5, the limit rod 21 is matched with the cylindrical hole, and the end of the limit rod 21 close to the stretching rod 23 is provided with a straight groove, and the straight groove is matched with the stretching rod 23, and the end of the limit rod 21 opposite to the straight groove is threadedly connected with a fixing cap 26, and the two sides of the push rod 22 close to the end of the stretching rod 23 are provided with a receiving groove 231 for accommodating the stretching rod 23, and the interior of the receiving groove 231 is fixedly connected with a compression spring 27, and the stretching rod 23 is elastically connected to the push rod 22 through the compression spring 27.

[0033] The above scheme is adopted: the buffer rod 25 plays a supporting and guiding role, ensuring the stability and reliability of the reset spring 24 during the working process; one end of the rotating rod 31 is rotatably connected to the first moving block 32, and the other end is rotatably connected to the fixed block 35. When the component is subjected to external force, the rotating rod 31 rotates around the connection point between it and the first moving block 32, and the external force is transmitted to the first moving block 32 and the inclined rod 33. The first moving block 32 is connected to the rotating rod 31 and the inclined rod 33. Under the action of the rotating rod 31 and the inclined rod 33, the first moving block 32 slides in the first moving groove, compressing the first spring 321, and converting the external force into elastic potential energy of the first spring 321. The inclined rod 33 connects the first moving block 32 and the second moving block 34. When the first moving block 32 moves, the inclined rod 33 will push the second moving block 34 to slide in the second moving groove, causing the second spring 341 to also undergo elastic deformation, further enhancing the buffering effect. Through the setting of the buffer mechanism 3, an effective The first and second springs 321 and 341 are compressed, and the first and second springs 321 and 341 are compressed. When the first and second springs 321 and 341 are compressed, they will produce elastic deformation, and the external force will be converted into elastic potential energy and stored. When the external force disappears, the elastic potential energy of the springs will be released, and the first and second moving blocks 32 and 34 will return to their initial positions, thereby playing a role of buffering and shock absorption, reducing the damage of external forces to the components, effectively buffering and absorbing the impact of external forces, greatly reducing the direct effect of external forces on the components, and significantly reducing the possibility of cracks, breakages and other damages to the components due to external force impacts, thereby improving the impact resistance of the components.

[0034] The second moving block 34 slides in the second moving groove under the push of the inclined rod 33, compresses the second spring 341, and works together with the first moving block 32 and the first spring 321 to absorb and buffer external force.

[0035] like Figures 1 to 6As shown, the surface of one end of the pushing rod 22 is fixedly connected to one end of the return spring 24, and the other end of the return spring 24 is connected to the inside of the limiting rod 21 near one end of the return spring 24. The other end of the rotating rod 31 is rotatably connected to a fixed block 35, and the fixed block 35 is fixedly connected to the bottom surface of the load-bearing plate 5. The first moving block 32 is adapted to the first moving groove, and one side of the first moving block 32 is fixedly connected to the first spring 321, and the first spring 321 is fixedly connected to the inside of the first moving groove, and the top of the second moving block 34 is fixedly connected to the second spring 341, and the second moving block 34 is adapted to the second moving groove, and the second spring 341 is fixedly connected to the inside of the second moving groove. There are two fixed columns 4, and the two fixed columns 4 are symmetrically distributed on both sides of the bottom surface of the beam 1. The first moving block 32 and the second moving block 34 are slidably connected to the first moving groove and the second moving groove respectively. The top surface of the beam 1 is provided with an installation groove for installing the load-bearing plate 5, and the two fixed columns 4 are in a state of being small on the top and large on the bottom.

[0036] The above scheme is adopted: cylindrical holes are opened inside the two ends of the beam 1 for installing the limit rod 21 to ensure that the position of the limit rod 21 in the beam 1 is accurate and stable; the first moving groove and the second moving groove are respectively opened on both sides of the inner bottom wall and the two sides of the inside of the beam 1 to provide guidance and limit for the movement of the first moving block 32 and the second moving block 34 to ensure the normal operation of the buffer mechanism 3; the fixed column 4 is installed at the bottom of the two ends of the beam 1, and a limit hole is opened inside to cooperate with the limit rod 21 to achieve the limit and fixation of the component. At the same time, it is in a state of being small at the top and large at the bottom, which can increase the connection stability with the foundation or other components; the load-bearing plate 5 is installed on the top of the beam 1 to bear external loads and transfer the loads to the beam 1 and other components, and at the same time provide a fixed connection point for the rotating rod 31; the first spring 321 and the second spring 341 are respectively fixedly connected between the first moving block 32 and the second moving block 34 and the first moving groove and the second moving groove, and elastically deform under the action of external force to absorb and buffer the external force and protect the component from damage.

[0037] The working principle and use process of the present invention are as follows: the limit mechanism 2 mainly realizes the limit and fixation of the component through the cooperation of the limit rod 21 and the limit hole of the fixing column 4. During installation, the two fixing columns 4 are first inserted into the two ends of the beam 1 respectively, and then the limit rod 21 is inserted into the limit hole of the fixing column 4, so that the limit rod 21 passes through the beam 1 and the fixing column 4, and then the push rod 22 inside the limit rod 21 is pushed to make the stretching rods 23 on both sides of the push rod 22 move to the position corresponding to the straight groove. At this time, the compression spring 27 releases the pressure, driving the stretching rod 23 to extend to the outside of the accommodating groove 231 and the limit rod 21, while the return spring 24 and the buffer rod 25 are in a compressed state. Afterwards, the push rod 22 is released, the return spring 24 and the buffer rod 25 release the pressure, and the limit rod 21 is pulled in the opposite direction, so that the stretching rod 23 contacts the beam 1 to form a stable triangle, and finally, the fixing cap 26 on the limit rod 21 is tightened, so that the beam 1 and the fixing column 4 can be fixed;

[0038] The buffer mechanism 3 mainly relies on the rotating rod 31, the inclined rod 33, the first moving block 32, the second moving block 34, the first spring 321 and the second spring 341 to realize the buffer function. When the component is subjected to external force, the external force will be transmitted to the rotating rod 31 and the inclined rod 33 through the load-bearing plate 5. The rotating rod 31 and the inclined rod 33 will move around the connection point with the first moving block 32, so that the first moving block 32 and the second moving block 34 slide in the first moving groove and the second moving groove, and compress the first spring 321 and the second spring 341. The first spring 321 and the second spring 341 will produce elastic deformation when compressed, and convert the external force into elastic potential energy and store it. When the external force disappears, the elastic potential energy of the spring will be released, so that the first moving block 32 and the second moving block 34 return to their initial positions, thereby playing a role of buffering and shock absorption, and reducing the damage of the external force to the component.
