Description

Technical Field

[0001] This utility model belongs to the field of stage truss technology, and in particular relates to a stage truss fixing buckle. Background Technology

[0002] A truss is a geometrically invariant structure composed of triangular frames made up of straight members. The connection points between the members are called nodes (or joints). Based on the axes of the truss members and the distribution of external forces, trusses can be divided into planar trusses and space trusses.

[0003] Modern performances typically involve assembling and installing stages using trusses. When stage truss lighting hooks are assembled and fixed to the truss, the upper and lower fasteners are usually connected by rotating pins. This connection method makes it difficult to fix the truss at various angles when a fixed connection is required, thus greatly reducing the applicable range of truss installations. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a stage truss fixing buckle, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a stage truss fixing buckle, including a main frame and a connecting threaded rod disposed on the upper end face of the main frame, and further including:

[0007] The fastener slides and engages with the upper end face of the connecting screw, and the fastener has a "U" shaped structure. A limiting mechanism is provided on the inner side of the fastener.

[0008] The locking mechanism is located at the lower end of the main frame and is used to connect with another set of connecting screws.

[0009] Furthermore, the upper end face of the main frame is provided with a uniformly spaced annular groove, and the lower end face of the fastener is fixed with a limiting protrusion. The fastener is sleeved on the outer surface of the connecting screw and is engaged with the limiting groove through the limiting protrusion.

[0010] Furthermore, the limiting mechanism includes a locking ring, an extension clip, and a truss member. The locking ring is located inside the fixed fastener and has a built-in rubber anti-slip pad. The extension clip is symmetrically fixed inside the locking ring and has an arc-shaped inner wall. The truss member is slidably engaged inside the locking ring.

[0011] Furthermore, an extension sleeve is fixed to the lower end of the inner wall of the fastener, and the extension sleeve is fitted onto the outer surface of the connecting screw.

[0012] Furthermore, an anti-slip pad is fixed to the upper surface of the fastener, and the anti-slip pad is arranged in an arc shape.

[0013] Furthermore, the locking mechanism includes a connecting sleeve and a threaded ring. The connecting sleeve is rotatably connected to the inner side of the main frame, and the threaded ring is evenly distributed on the outer surface of the connecting screw. The connecting sleeve has an internal thread and is connected to the outer surface of the connecting screw.

[0014] This utility model has the following beneficial effects:

[0015] This invention features a fastener that can be fitted onto the outside of the connecting rod, and multiple sets of limiting protrusions that can engage with limiting grooves, allowing for adjustment of the fastener's position. Since the fastener's placement angle is adjustable, the angle of the truss components can be controlled as needed. Then, a connecting sleeve can be threaded onto the outside of the connecting rod and tightened into the threaded ring, thereby clamping and limiting multiple truss components, ensuring the subsequent installation of the truss components.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-4 As shown, this utility model is a stage truss fixing buckle, including a main frame 1 and a connecting threaded rod 2 disposed on the upper end face of the main frame 1, and also includes:

[0025] The fixing fastener 4 is slidably engaged with the upper end face of the connecting threaded rod 2, and the fixing fastener 4 is arranged in a "U" shape. A limiting mechanism is provided on the inner side of the fixing fastener 4. The upper end face of the main frame 1 is evenly provided with a limiting groove 3 in a ring shape. A limiting protrusion 5 is fixed on the lower end face of the fixing fastener 4, and the fixing fastener 4 is sleeved on the outer surface of the connecting threaded rod 2. It is engaged with the limiting groove 3 through the limiting protrusion 5. By adapting the limiting protrusion 5 to the limiting groove 3, the position of the fixing fastener 4 can be adjusted. When the angle of the fixing fastener 4 can be adjusted, the angle of the truss member 9 can be adjusted as needed. By controlling the process, the applicability of the equipment can be further improved. The limiting mechanism includes a locking ring 6, an extension clip 7, and a truss component 9. The locking ring 6 is located inside the fixed fastener 4 and has a built-in rubber anti-slip pad. The extension clip 7 is symmetrically fixed inside the locking ring 6 and has an arc-shaped inner wall. The truss component 9 is slidably engaged inside the locking ring 6. Since the fixed fastener 4 has an arc-shaped structure, the locking ring 6 can be sleeved on the outside of the truss component 9. The extension clip 7 can restrain and limit the truss component 9, preventing it from shifting.

[0026] An extension sleeve 8 is fixed to the lower end of the inner wall of the fastener 4, and the extension sleeve 8 is sleeved on the outer surface of the connecting screw 2. When the connecting sleeve 11 is sleeved on the outside of the connecting screw 2 and moves downward, the fastener 4 can be pushed downward, thereby clamping and limiting the truss member 9 through the locking ring 6, which can prevent the truss member 9 from shifting or deviating. Since the extension sleeve 8 can be sleeved on the outside of the connecting screw 2, the fastener 4 can be restrained and limited, which can prevent the fastener 4 from shifting.

[0027] A locking mechanism is located at the lower end of the main frame 1 and is used to connect with another set of connecting screws 2. The locking mechanism includes a connecting sleeve 11 and a threaded ring 12. The connecting sleeve 11 is rotatably connected to the inner side of the main frame 1, and the threaded ring 12 is evenly distributed on the outer surface of the connecting screw 2. The connecting sleeve 11 has an internal thread and is connected to the outer surface of the connecting screw 2. The connecting sleeve 11 can be rotatably connected to the outer side of the connecting screw 2, and the threaded ring 12 allows the connecting sleeve 11 to connect with it. This not only allows multiple sets of fixing buckles to be connected, but also allows it to contact the fixing fastener 4 to lock the truss member 9, preventing the truss member 9 from shifting or shaking. The upper end face of the fixing fastener 4 is fixed with an anti-slip pad 10, and the anti-slip pad 10 is arc-shaped. The lower end face of the connecting sleeve 11 can contact the anti-slip pad 10, which can prevent the connecting sleeve 11 from loosening during fixing and affecting the clamping effect of the subsequent truss member 9.

[0028] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
