Description

Technical Field

[0001] The utility model relates to the technical field of truss fixed connection, in particular to a truss fixed connection structure. Background Art

[0002] In the process of building construction, trusses are often used: a structure made of rods connected to each other with hinges at both ends. Trusses are generally plane or spatial structures with triangular units composed of straight rods. Truss rods mainly bear axial tension or pressure, so as to make full use of the strength of the material. When the span is large, it can save materials, reduce deadweight and increase rigidity compared to solid beams. Therefore, most trusses are used in building construction scaffolds and lifting platforms.

[0003] According to the patent with publication number CN212956946U, a truss connection node and a truss structure are disclosed. The truss connection node includes: a node ball, on which at least one bolt hole is arranged; a cone head, which is constructed as a cone-shaped structure, and a through hole is formed at the position of the small end of the cone; a connecting bolt, which passes through the small end of the cone of the cone head and is suitable for being connected with the bolt hole through a thread.

[0004] By adopting the above scheme, the connecting bolt is connected to the bolt hole through a thread, so that the node ball is connected to the cone head, so that the truss connection node does not need to be assembled by a large amount of welding. The bolt connection can effectively reduce the size of the node ball. Since the truss is generally processed and manufactured in a factory, and a large number of connecting rods are connected to the node ball on site, the above scheme uses bolts to connect the connecting rods and the node ball, which makes the entire truss assembly process too long, resulting in low work efficiency of workers, and there are certain shortcomings. To this end, we provide a truss fixed connection structure to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] like Figure 1 to Figure 6 As shown, a truss fixed connection structure includes a node ball 1, an insertion block 2 is fixedly connected to the left side of the node ball 1, a weighing rod 3 is slidably connected to the outer surface of the insertion block 2, the right side of the weighing rod 3 is in contact with the left side of the node ball 1, and the inside of the weighing rod 3 is provided with a groove adapted to the insertion block 2, so that the insertion block 2 can be easily inserted into the inside of the weighing rod 3.

[0026] A first limiting mechanism 4 is arranged inside the weighing rod 3, and the first limiting mechanism 4 includes a sliding block 403. The left end of the inserted block 2 is provided with a rounded corner that can facilitate the sliding block 403. The outer surface of the sliding block 403 is respectively slidably connected to the inner wall of the inserted block 2 and the inner wall of the weighing rod 3. The bottom surface of the inserted block 2 is provided with a groove that is adapted to the sliding block 403, which can facilitate the sliding block 403 to be inserted into the interior of the inserted block 2 to limit the inserted block 2.

[0027] The bottom surface of the sliding surface block 403 is fixedly connected with a pull rod 402, the outer surface of the pull rod 402 is slidably connected with the inner wall of the weighing rod 3, and the bottom end of the pull rod 402 is fixedly connected with a pull plate 401. By using the provided pull plate 401, the pull rod 402 and the sliding surface block 403 can be easily pulled to release the limit on the insertion block 2. The outer surface of the pull rod 402 is wound with a first spring 404, the first spring 404 is a tension spring, and the upper and lower ends of the first spring 404 are respectively fixedly connected with the outer surface of the weighing rod 3 and the upper surface of the pull plate 401. The provided first spring 404 is in a relaxed state in a natural state. By using the provided first spring 404, the sliding surface block 403 can be driven to maintain the limit on the insertion block 2. By arranging the first limiting mechanism 4 below the weighing rod 3, when the gravity of the worker or the building object acts on the upper surface of the weighing rod 3, the slots that need to be adapted to the sliding surface block 403 will not affect the bearing capacity of the weighing rod 3.

[0028] The weighing rod 3 is internally slidably connected with a push plate 5, and the left end of the push plate 5 is fixedly connected with a push spring 6, which is a compression spring. The left end of the push spring 6 is fixedly connected to the inner wall of the weighing rod 3. By using the cooperation between the set push plate 5 and the push spring 6, the node ball 1 and the insertion block 2 can be pushed apart for a distance when the node ball 1 is disassembled, so that the node ball 1 and the weighing rod 3 can be separated conveniently.

[0029] The upper and lower ends of the node ball 1 are respectively fixedly connected with a lower support rod 10 and an upper connecting rod 11. The outside of the weighing rod 3 is provided with a reinforcement mechanism 7, which includes a ring plate 701. The inner wall of the ring plate 701 is fixedly connected to the outer surface of the weighing rod 3. The outer surface of the ring plate 701 is fixedly connected with a bearing groove 702. By using the provided ring plate 701, the weighing rod 3 and the bearing groove 702 can be connected, thereby strengthening the connection between the bearing groove 702 and the weighing rod 3. The inner wall of the bearing groove 702 is rotatably connected with an inclined rotating plate 703, and the outer surface of the inclined rotating plate 703 is rotatably connected with a driving block 704. A clamping mechanism 8 is provided on the outside of the lower support rod 10, and the clamping mechanism 8 includes a semicircular sleeve groove 801 and a sleeve plate 802. The outer surface of the driving block 704 is fixedly connected to the outer surface of the semicircular sleeve groove 801. By using the cooperation between the set bearing groove 702, the inclined plate 703 and the driving block 704, the angle of the semicircular sleeve groove 801 can be adjusted, so that the semicircular sleeve groove 801 can be easily fitted with the outer surface of the lower support rod 10.

[0030] The inner wall of the semicircular sleeve groove 801 is slidably connected to two insertion plates 803. The inner wall of the semicircular sleeve groove 801 is provided with a groove adapted to the insertion plate 803, so that the insertion plate 803 can be easily inserted into the interior of the semicircular sleeve groove 801. The side surfaces of the two insertion plates 803 close to the sleeve plate 802 are fixedly connected to the outer surface of the sleeve plate 802.

[0031] Two second limiting mechanisms 9 are arranged inside the clamping mechanism 8, and the second limiting mechanism 9 includes a lifting plate 901, and the bottom surface of the lifting plate 901 is fixedly connected with an insertion rod 902, and the outer surfaces of the insertion rod 902 are slidingly connected with the inner walls of the semicircular sleeve groove 801 and the insertion plate 803 respectively. By using the set insertion rod 902, the semicircular sleeve groove 801 and the insertion plate 803 can be limited, and the inner top wall of the semicircular sleeve groove 801 is provided with a through opening adapted to the insertion rod 902, and the interior of the insertion plate 803 is provided with an opening adapted to the insertion rod 902.

[0032] A second spring 903 is wound around the outer surface of the insertion rod 902. The second spring 903 is a tension spring. The upper and lower ends of the second spring 903 are respectively fixedly connected to the bottom surface of the lifting plate 901 and the upper surface of the semicircular groove 801. By using the set second spring 903, the insertion rod 902 can be driven to continuously maintain the limit position on the insertion plate 803.

[0033] Working principle: When the truss needs to be connected, by inserting the insert block 2 into the inside of the weighing rod 3, the insert block 2 can push the sliding block 403 away until the right side of the weighing rod 3 contacts the outer surface of the node ball 1. Under the elastic force of the first spring 404, the pull plate 401, the pull rod 402 and the sliding block 403 can be reset, and the sliding block 403 can limit the slot on the outer surface of the insert block 2, and finally the connection between the node ball 1 and the weighing rod 3 can be achieved. By pulling the pull plate 401 downward, the pull rod 402 and the sliding block 403 can be moved, so that the sliding block 403 can release the limit on the insert block 2. Under the synchronous action of the push plate 5 and the push spring 6, the push plate 5 can be driven to push the insert block 2, and finally the node ball 1 and the weighing rod 3 can be quickly disassembled. By rotating the inclined plate 703 and the driving block 704, the semicircular groove 801 can be driven to fit the outer surface of the lower support rod 10. By pulling the lifting plate 901 upward, the insertion rod 902 can be driven to move upward, and then the insertion plate 803 is inserted into the interior of the semicircular groove 801, and the lifting plate 901 is released. Under the elastic force of the two second springs 903, the two insertion rods 902 can be driven to limit the insertion plate 803. Finally, with the cooperation of the reinforcement mechanism 7, the clamping mechanism 8 and the second limiting mechanism 9, the weighing rod 3 can be reinforced when it is subjected to force.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
