In the description of the present application, the meaning of "a plurality of" is two or more, unless expressly and specifically defined otherwise.

[0020] As shown in Figures 1-6 The present application provides an assembled steel structure assembly, which comprises two steel bodies 10, a triangular locking groove 11 is formed on each side between the two steel bodies 10, and specifically, when the two steel bodies 10 are spliced together, a complete triangular locking groove 11 is formed between them. A triangular plate 21, three insertion plates, and a driving assembly 30 are arranged in each triangular locking groove 11.

[0021] The locking mechanism 20 comprises a triangular plate 21, three insertion plates, and a driving assembly 30.

[0022] The triangular plate 21 is adapted to the triangular groove, and a triangular receiving groove extending inwardly is formed on the front side of the triangular plate 21. A guide groove 23 extending outwardly in the transverse direction is formed on each of the three inner side walls of the triangular locking groove 11.

[0023] The three insertion plates are arranged in the three guide grooves 23 respectively, and the insertion plates are in sliding contact with the inner walls of the guide grooves 23. The first end of the insertion plate is located in the insertion groove 22, and the second end of the insertion plate is located in the triangular receiving groove, and the insertion plate is adapted to the insertion groove 22.

[0024] The driving assembly 30 is used to control the three insertion plates to move outwardly or outwardly at the same time.

[0025] In the initial state, the insertion plates of the locking mechanism 20 are completely hidden in the triangular plate 21.

[0026] The specific working process of the locking mechanism 20 is as follows: first, the worker puts the triangular plate 21 into the triangular receiving groove, at this time the insertion plate is aligned with the corresponding insertion groove 22. Then the worker controls the three insertion plates to move outwardly and insert into the corresponding insertion groove 22 at the same time through the driving assembly 30, so that the triangular plate 21 is fixed in the triangular receiving groove, and the two steel bodies 10 are fixedly connected together.

[0027] The operation steps of the present application are simple, and the worker only needs to put the triangular plate 21 into the triangular receiving groove, and control the driving assembly 30, so that the assembly efficiency is higher. Compared with the traditional bolt or rivet connection, the structure stability of the triangular plate 21 adopted by the present application is better, and the effect of resisting external force is better, so the safety risk is small.

[0028] In one embodiment, the driving assembly 30 comprises a fixed column 31, a rotating column 32, and a threaded column 33.

[0029] The fixed column 31 is fixedly installed at the bottom of the inner wall of the triangular accommodating groove, and a threaded hole is formed in the top of the fixed column 31. The rotating column 32 is arranged outside the fixed column 31, and three guide plates 34 are arranged on the outer circumferential surface of the rotating column 32 in sequence and at equal intervals, and the three guide plates 34 are arranged in one-to-one correspondence with the three insertion plates. The guide plate 34 is fixedly connected with the rotating column 32, and an arc-shaped groove 35 is formed in the guide plate 34. A transmission shaft 36 is arranged in the arc-shaped groove 35, and the transmission shaft 36 is in contact with the inner wall of the arc-shaped groove 35. The transmission shaft 36 is connected with the corresponding insertion plate. The first end of the threaded column 33 is fixedly connected with the rotating column 32, and the second end of the threaded column 33 is threadedly matched with the threaded hole in the fixed column 31.

[0030] In the initial state, the threaded column 33 is threadedly matched with the threaded hole, but is not tightened. The transmission shaft 36 is close to the inner side of the arc-shaped groove 35, and at this time, the insertion plate is completely hidden in the triangular plate 21.

[0031] When the driving assembly 30 works, the worker twists the rotating column 32, and the rotating column 32 drives the guide plate 34 and the threaded column 33 to rotate. On the one hand, under the action of the arc-shaped groove 35, the transmission shaft 36 moves outward, and then drives the insertion block to move outward and insert into the corresponding insertion slot 22. On the other hand, the threaded column 33 is gradually tightened, so that the rotating column 32 and the fixed column 31 are tightly connected together, so that the two steel bodies 10 are fixedly connected together, and the insertion block is prevented from returning to the triangular plate 21.

[0032] In an embodiment, the transmission shaft 36 is rotatably connected with the insertion plate, and the transmission shaft 36 is also in rolling contact with the inner wall of the arc-shaped groove 35.

[0033] In this way, when the worker twists the rotating column 32, the transmission shaft 36 rolls on the inner wall of the arc-shaped groove 35, thereby reducing the friction between the transmission shaft 36 and the inner wall of the arc-shaped groove 35, and the movement of the insertion plate is more smooth.

[0034] In an embodiment, an inner hexagonal hole 37 is formed in the front side of the rotating column 32. The worker inserts the corresponding inner hexagonal wrench into the inner hexagonal hole 37, and operates the inner hexagonal wrench to drive the rotating column 32 to rotate, which further facilitates the operation of the worker.

[0035] In the embodiment, the worker only needs to insert the inner hexagonal wrench into the inner hexagonal hole 37 and tighten it, so that the three insertion plates are driven to be inserted into the corresponding insertion slots 22 under the action of the rotating column 32, the guide plate 34, the arc-shaped groove 35 and the transmission shaft 36, which further facilitates the operation.

[0036] In an embodiment, a plurality of reinforcing assemblies 40 are further arranged between the two steel bodies 10.

[0037] The reinforcing assembly 40 comprises a positioning sleeve 41 and a reinforcing plate 42. The positioning sleeve 41 is fixedly installed on one of the steel bodies 10, and the positioning sleeve 41 is provided with a longitudinal positioning sleeve hole. The first end of the reinforcing plate 42 is fixedly connected with the other steel body 10, and the second end of the reinforcing plate 42 extends outward after passing through the positioning sleeve 41. The side surface of the second end of the reinforcing plate 42 is provided with a rectangular slot 43 extending inward, and the rectangular slot 43 is provided with a rectangular plate 44 and a spring 45. The rectangular plate 44 is arranged in the rectangular slot 43 and in sliding contact with the inner wall of the rectangular slot 43. The rectangular plate 44 is adapted to the rectangular slot 43, and the rectangular plate 44 is in contact with the positioning sleeve 41. The first end of the spring 45 is fixedly connected with the rectangular plate 44, and the second end of the spring 45 is fixedly connected with the inner wall of the rectangular slot 43.

[0038] In the initial state, part of the rectangular plate 44 is located in the rectangular slot 43, and the other part of the rectangular plate 44 is located outside the rectangular slot 43, and at this time the spring 45 is in a natural elongation state.

[0039] In assembly, the staff first aligns the reinforcing plate 42 with the positioning sleeve 41, and then presses the rectangular plate 44 into the rectangular slot 43, and then controls the downward movement of the upper steel body 10. After the positioning sleeve 41 passes through the reinforcing plate 42, the rectangular plate 44 will automatically extend under the action of the spring 45, the rectangular plate 44 is in contact with the positioning sleeve 41, at this time the reinforcing plate 42 cannot be pulled out of the positioning sleeve 41, and the two steel bodies 10 are fixedly connected together.

[0040] The design of the reinforcing assembly 40 plays a reinforcing role in the connection between the two steel bodies 10, cooperates with the triangular plate 21 and the triangular accommodating slot, and further improves the stability.

[0041] In an embodiment, the outer side surface of the rectangular block is provided with a guide surface 46 inclined upward and extending inward.

[0042] When the staff controls the downward movement of the upper steel body 10, the guide surface 46 will first contact the bottom of the positioning sleeve 41, the rectangular plate 44 will be pushed inward and hidden in the rectangular slot 43, and after the positioning sleeve 41 passes through the reinforcing plate 42, the rectangular plate 44 will automatically extend under the action of the spring 45, the rectangular plate 44 is in contact with the positioning sleeve 41, at this time the reinforcing plate 42 cannot be pulled out of the positioning sleeve 41, and the two steel bodies 10 are fixedly connected together.

[0043] The design of the guide surface 46 can make the rectangular plate 44 automatically hidden in the rectangular slot 43 when the two steel bodies 10 are spliced, and then automatically pop out under the action of the spring 45, without the staff needing to press the rectangular plate 44 into the rectangular slot 43, further facilitating the operation.

[0044] In one embodiment, two rectangular grooves 43 are respectively formed on the two sides of the second end of the reinforcing plate 42. Each rectangular groove 43 has a corresponding rectangular plate 44 and a spring 45. In this way, the connection between the reinforcing plate 42 and the positioning sleeve 41 is more stable, further improving the stability of the present application.

[0045] In one embodiment, the reinforcing plate 42 has a longitudinal connecting groove 47 formed inside, and a steel wire column 48 is arranged in the connecting groove 47. The steel wire column 48 is fixedly connected with the inside of the connecting groove 47, and is twisted by a plurality of steel wire ropes.

[0046] The steel wire rope has the advantages of high strength, light weight, stable operation, not easy to break suddenly, large safety factor, wear resistance, shock resistance, good corrosion resistance, good softness, etc. The steel wire column 48 is twisted by a plurality of steel wire ropes, and has excellent performance.

[0047] Since the steel structure 10 may encounter earthquakes, impacts and other situations during use. Therefore, the design of the steel wire column 48 can further improve the strength of the reinforcing plate 42. If the reinforcing plate 42 breaks under the action of external force, the steel wire column 48 can still connect the two steel bodies 10 together to avoid the steel bodies 10 from scattering and falling, which is convenient for subsequent cleaning personnel to concentrate on cleaning, and can prevent different steel bodies 10 from falling in different directions, further improving the safety.

[0048] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be realized in other specific forms without departing from the spirit or essential characteristics of the present application.
