[0029] The present application will be further described in detail below with reference to the accompanying drawings and examples.
[0030] Reference Figures 1 to 5The embodiment of the present application provides a truss quick connection structure, including a truss body 1, with mounting plates 5 fixedly installed at both ends of the truss body 1, a mounting component 2 is arranged between the two mounting plates 5, a fastening component 3 is arranged inside the mounting component 2, and an auxiliary component 4 is arranged on the front of the mounting component 2, and the mounting component 2 includes a mounting block 21, and positioning columns 22 are fixedly installed on the left side and the top of the mounting block 21, and positioning holes 23 are opened inside the mounting plate 5, and the positioning columns 22 are inserted into the corresponding positioning holes 23, and the mounting plate 5 is attached to the outside of the mounting block 21.
[0031] The fastening assembly 3 includes a first rotating rod 33 and a second rotating rod 36. The first rotating rod 33 is rotatably connected to the left inner wall of the mounting block 21, and the second rotating rod 36 is rotatably connected to the inner bottom of the mounting block 21. The left end of the first rotating rod 33 is located on the left side of the mounting block 21 and is fixedly mounted with the first fastening plate 31. The top of the second rotating rod 36 is located above the mounting block 21 and is fixedly mounted with the second fastening plate 37. A matching groove 32 is opened inside the mounting plate 5, and the first fastening plate 31 and the second fastening plate 37 pass through the corresponding matching groove 32.
[0032] A first bevel gear 34 is fixedly mounted on the end surface of the first rotating rod 33 and located within the mounting block 21. A second bevel gear 35 is fixedly mounted on the outer side of the second rotating rod 36, and the first bevel gear 34 and the second bevel gear 35 mesh with each other. A worm 39 is rotatably connected between the front and rear inner walls of the mounting block 21. A worm wheel 38 is fixedly mounted on the outer side of the second rotating rod 36, and the worm wheel 38 and the worm 39 mesh with each other.
[0033] When the first and second fastening plates 31 and 37 are connected, the first and second fastening plates 31 and 37 are respectively inserted into the corresponding matching grooves 32. After passing through, the worm gear 38 is driven to rotate by rotating the worm 39. The rotation of the worm gear 38 drives the second rotating rod 36 to rotate. The rotation of the second rotating rod 36 can drive the first rotating rod 33 to rotate synchronously through the first bevel gear 34 and the second bevel gear 35, thereby driving the first fastening plate 31 and the second fastening plate 37 on the outside to rotate synchronously. By rotating the first fastening plate 31 and the second fastening plate 37 synchronously by ninety degrees, they can be buckled on the outside of the corresponding mounting plate 5 and cooperate with the positioning column 22 to fix the truss body 1, thereby achieving the purpose of convenient truss fixation. After fixation, the self-locking effect of the worm gear 38 and the worm 39 can ensure the stability of the truss after fixation.
[0034] Reference Figures 1 to 5 In one aspect of this embodiment, the front side of the mounting block 21 is rotatably connected to the screw 42 , and the front side of the worm 39 is movable through the inner wall of the mounting block 21 and fixedly connected to the screw 42 .
[0035] A shift rod 41 is fixedly mounted on the front of the screw rod 42 , a nut 43 is threadedly connected to the outside of the screw rod 42 , a friction plate 44 is fixedly mounted on the back of the nut 43 , and the friction plate 44 is sleeved on the outside of the screw rod 42 and fits on the front of the mounting block 21 .
[0036] In this embodiment, when the worm 39 is rotated, the screw 42 is rotated by the lever 41, and the rotation of the screw 42 can drive the worm 39 to rotate, thereby realizing the rotation of the worm wheel 38. After the truss body 1 is fixed, the nut 43 can be rotated to drive the nut 43 to move on the screw 42, and the friction plate 44 can be moved to the outside of the mounting block 21. The friction plate 44 is squeezed on the outside of the mounting block 21, and the screw 42 is fixed by the friction force between the friction plate 44 and the mounting block 21, thereby further fixing the internal worm 39. The self-locking effect of the worm wheel 38 and the worm 39, combined with the friction effect of the friction plate 44, can improve the stability of the fixation of the truss body 1.
[0037] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.
[0038] Working principle: When connecting the two truss bodies 1, align the positioning column 22 with the corresponding positioning hole 23 and insert it. When inserting, the first fastening plate 31 and the second fastening plate 37 pass through the corresponding matching groove 32 respectively. After passing through, the worm gear 38 is driven to rotate by rotating the worm 39. The rotation of the worm gear 38 drives the second rotating rod 36 to rotate. The rotation of the second rotating rod 36 can drive the first rotating rod 33 to rotate synchronously through the first bevel gear 34 and the second bevel gear 35, thereby driving the outer first fastening plate 31 and the second fastening plate 37 to rotate synchronously. By rotating the first fastening plate 31 and the second fastening plate 37 synchronously by ninety degrees, they can be buckled on the outer side of the corresponding mounting plate 5 and cooperate with the positioning column 22 to achieve the fixation of the truss body 1, thereby achieving the purpose of convenient truss fixation. After fixation, the self-locking effect of the worm gear 38 and worm 39 can ensure the stability of the truss after fixation. When the worm 39 is rotated, the screw 42 is rotated by the lever 41. The rotation of the screw 42 can drive the worm 39 to rotate, thereby realizing the rotation of the worm gear 38. After the truss body 1 is fixed, the nut 43 can be rotated to drive the nut 43 to move on the screw 42, and the friction plate 44 can be moved to the outside of the mounting block 21. The friction plate 44 is squeezed on the outside of the mounting block 21, and the screw 42 is fixed by the friction force between the friction plate 44 and the mounting block 21, thereby further fixing the internal worm 39. The self-locking effect of the worm gear 38 and worm 39, combined with the friction effect of the friction plate 44, improves the stability of the fixation of the truss body 1.
