[0002] A tube truss refers to a lattice structure composed of round rods connected to each other at the ends. Its cross-section is generally triangular and evenly distributed. It has large rigidity and bending and torsional bearing capacity, simple structure, and easy construction. The tube truss structure has superior overall performance and beautiful shape. The forces on each rod are clear, and it is suitable for large-span spatial structures.

[0003] In the prior art, when connecting tube trusses, connecting shafts are mostly used to connect two trusses and then weld them. For some projects that need to meet deadlines, the trusses need to be built quickly. The workers carry connecting shafts, splice the suspended trusses and then weld them. Since the connecting shafts in traditional technology are mostly solid shafts, it is difficult to carry multiple, so the workers need to take off and land more frequently, which wastes time in building the trusses. At the same time, the solid connecting shafts are easy to slide into the truss, making it difficult to quickly position the two trusses, and the installation and connection of the tube truss is not convenient enough.

DETAILED DESCRIPTION

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0018] Example: See Figure 1 - Figure 4 The utility model provides a technical solution: a new type of pipe truss that is easy to install, comprising: a triangular truss 1, the inner wall of the triangular truss 1 is provided with a connecting hole 3; a connector 2, the outer wall of the connector 2 is slidably connected to the inner wall of the triangular truss 1; a limiting ring 4, the outer wall of the limiting ring 4 is fixedly connected to the inner wall of the triangular truss 1; the connector 2 comprises a rotating shaft 21, the outer wall of the rotating shaft 21 is threadedly connected with a threaded ring 23 through a threaded groove 22, the side of the threaded ring 23 away from the rotating shaft 21 is fixedly connected with a push plate 24, the side of the push plate 24 away from the threaded ring 23 is fixedly connected with a connecting column 25, the side of the connecting column 25 away from the push plate 24 is fixedly connected with a connecting plate 26, the outer wall of the connecting plate 26 is fixedly connected to a limiting device 27, a limiting column 28 is arranged on the outside of the limiting device 27, and the outer wall of the limiting column 28 is slidably connected There is a magnetic tube 29, and the triangular trusses 1 on the left and right sides are connected through the connector 2. The triangular truss 1 is moved and placed in the gap between the limit column 28 and the magnetic tube 29 until it can no longer be pushed. Then the two magnetically adsorbed magnetic tubes 29 are pulled apart to expose the internal structure of the connector 2. At this time, the staff rotates the rotating shaft 21. Since the thread grooves 22 on the left and right sides of the rotating shaft 21 are symmetrical to each other, the thread grooves 22 on both sides rotate in opposite directions. When the rotating shaft 21 rotates, the threaded ring 23 is driven to move through the threaded groove 22, driving the threaded rings 23 on both sides to approach or move away from each other. During the connection process, the threaded rings 23 are controlled to move away from each other, and the threaded rings 23 drive the push plate 24 to move. The moving push plate 24 pushes the connecting column 25 out of the limit column 28, so that the limit device 27 enters deeper into the triangular truss 1.

[0019] The outer wall of the limit column 28 is slidably connected to the inner wall of the triangular truss 1, the inner wall of the magnetic tube 29 is slidably connected to the outer wall of the triangular truss 1, the inner wall of the triangular truss 1 is slidably connected to the outer wall of the connecting plate 26, the two sides of the rotating shaft 21 are rotatably connected to the inner wall of the limit column 28, the inner wall of the limit column 28 is slidably connected to the outer wall of the connecting column 25, and before being unfolded, the connector 2 is shorter than the ordinary connecting column 25, so that workers working in high-altitude construction can carry more connectors 2 in a backpack with a fixed volume.

[0020] The limiting device 27 includes a positioning shaft 271, the outer wall of the positioning shaft 271 is rotatably connected to a triangular rotating block 272 through a connecting hole 273, and the connecting hole 273 is provided in the wall of the triangular rotating block 272, and the two sides of the triangular rotating block 272 are fixedly connected to the limiting shaft 274, the outer wall of the limiting shaft 274 is slidably connected to the inner wall of the positioning shaft 271 through a sliding groove 275, and the sliding groove 275 is provided in the wall of the positioning shaft 271, and a compression spring 276 is provided on the outside of the limiting shaft 274. When in use, the rotating shaft 21 is rotated, and then the positioning shaft 271 is pushed into the limiting ring 4 of the connecting hole 3 through the threaded ring 23, the push plate 24, the connecting column 25 and the connecting plate 26. During the movement, the limiting ring 4 squeezes the triangular rotating block 272, and the triangular rotating block 272 rotates around the connecting hole 273 and is then locked into the positioning shaft 271. At this time, the compression spring 276 is squeezed by the triangular rotating block 272. When the triangular rotating block 272 passes through the limiting ring 4, the previously compressed compression spring 276 pushes the triangular rotating block 272 out, and the triangular rotating block 272 slides through the limiting shaft 274 and the sliding groove 275, and is finally prevented from further movement by the sliding groove 275. At this time, the rotating shaft 21 is rotated in the opposite direction, and the raised triangular rotating block 272 will press against the limiting ring 4, so that the connection between the triangular truss 1 and the connector 2 on both sides is tighter.

[0021] One end of the compression spring 276 is fixedly connected to the outer wall of the positioning shaft 271 , and the other end of the compression spring 276 is fixedly connected to the outer wall of the triangular rotating block 272 . The outer wall of the positioning shaft 271 is fixedly connected to one end of the connecting plate 26 away from the connecting column 25 .

[0022] Working principle:

[0023] When in use, the triangular trusses 1 on the left and right sides are connected through the connector 2, and the triangular truss 1 is moved and placed in the gap between the limit column 28 and the magnetic tube 29 until it can no longer be pushed, and then the two magnetically adsorbed magnetic tubes 29 are pulled apart to expose the internal structure of the connector 2. At this time, the staff rotates the shaft 21. Since the thread grooves 22 on the left and right sides of the shaft 21 are symmetrical to each other, the thread grooves 22 on both sides rotate in opposite directions. When the shaft 21 rotates, the thread ring 23 is driven to move through the thread groove 22, driving the thread rings 23 on both sides to approach or move away from each other. During the connection process, the thread rings 23 are controlled to move away from each other, and the thread ring 23 drives the push plate 24 to move. The moving push plate 24 pushes the connecting column 25 out of the limit column 28, so that the limit device 27 enters deeper into the triangular truss 1. Before being unfolded, the connector 2 is shorter than the ordinary connecting column 25, so that the staff of high-altitude construction can carry more connectors 2 in a backpack with a fixed volume, reducing the number of times the staff take off and land, thereby speeding up the construction time.

[0024] The limiting device 27 is provided to make the triangular truss 1 more tightly connected, which is convenient for the staff to weld. When in use, the rotating shaft 21 is rotated, and then the positioning shaft 271 is pushed into the limiting ring 4 of the connecting hole 3 through the threaded ring 23, the pushing plate 24, the connecting column 25 and the connecting plate 26. During the movement, the limiting ring 4 squeezes the triangular rotating block 272, and the triangular rotating block 272 rotates around the connecting hole 273 and then locks into the positioning shaft 271. At this time, the compression spring 276 is squeezed by the triangular rotating block 272. When the triangular rotating block 272 passes through the limiting ring 4, the previously compressed compression spring 276 pushes the triangular rotating block 272 out, and the triangular rotating block 272 slides through the limiting shaft 274 and the sliding groove 275, and is finally prevented from further movement by the sliding groove 275. At this time, the rotating shaft 21 is rotated in the opposite direction, and the raised triangular rotating block 272 will press against the limiting ring 4, so that the connection between the triangular truss 1 and the connector 2 on both sides is tighter, which is convenient for the staff to weld.

[0025] The magnetic tube 29 is arranged on the limit column 28 to increase the connection stability of the connector 2. At the same time, the internal structure of the connector 2 can also be protected, thereby reducing the maintenance and replacement costs of the connector 2 due to connection problems, thereby achieving the purpose of extending the service life of the connector 2. Since the internal structure of the connector 2 is protected, the internal components of the connector 2 are effectively prevented from being corroded by external factors such as dust and moisture, and a good internal working environment is maintained. The stable connection helps to improve the safety of the pipe truss and reduce potential safety risks.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
