[0027] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0028] The present application embodiment discloses a multifunctional scaffold for construction engineering. Figure 1 The multifunctional scaffold for construction engineering includes a plurality of mutually connected assembly units 1, each assembly unit 1 includes a first assembly tube 11, a second assembly tube 12 and an assembly mechanism 2, the first assembly tube 11 and the second assembly tube 12 can be assembled horizontally or vertically, so as to facilitate the construction of the scaffold, and the first assembly tube 11 and the second assembly tube 12 are detachably connected through the assembly mechanism 2, so as to facilitate the extension of the height or length of the scaffold.

[0029] Reference Figure 1 , Figure 2The assembly mechanism 2 includes a support rod 21, a clamping block 22, a fixing plate 23 and a spring plate 24. One end of the first assembly tube 11 is connected to four support rods 21. The support rods 21 are welded and fixed to the edge of the end wall of the first assembly tube 11, and the four support rods 21 are distributed at equal angles along the circumference of the central axis of the first assembly tube 11. The end of the support rod 21 away from the first assembly tube 11 is integrally connected to the clamping block 22. The clamping block 22 is perpendicular to the support rod 21 so that a groove is formed therebetween. The inner wall of the second assembly tube 12 is welded and fixed to a circular fixing plate 23. The fixing plate 23 is perpendicular to the central axis of the second assembly tube 12 so that one end of the second assembly tube 12 forms a circular groove 121 and the spring plate 24 is covered on the circular groove 121. The spring plate 24 is made of elastic spring steel and other materials. The spring plate 24 is circular and its edge is welded and fixed to the inner wall of the circular groove 121.

[0030] Reference Figure 2 , Figure 3 The spring piece 24 is provided with a socket 241 and a limiting hole 242 which are connected to the circular groove 121. The limiting hole 242 is circular and located at the center of the spring piece 24, that is, the limiting hole 242 is coaxially distributed with the second assembly tube 12. There are four sockets 241 which are located at the edge of the spring piece 24. The four sockets 241 are distributed at equal angles along the circumferential direction of the central axis of the second assembly tube 12.

[0031] The support rod 21 can be inserted into the insertion hole 241 and drive the clamping block 22 to enter the circular groove 121. When the first assembly tube 11 and the second assembly tube 12 rotate relatively, the support rod 21 pushes the clamping block 22 into the interlayer formed between the spring piece 24 and the bottom wall of the circular groove 121, thereby realizing the rotation clamping. In order to improve the stability of the rotation clamping, on the one hand, a through hole 122 is formed through the side wall of the circular groove 121, and a stud 123 is threadedly penetrated on the through hole 122. The stud 123 extends to a section in the circular groove 121 opposite to the opening of the insertion hole 241. When the clamping block 22 is engaged with the circular groove 121, the stud 123 extends to a section in the circular groove 121 on the side of the support rod 21 away from the clamping block 22, thereby preventing the clamping block 22 from resetting, preventing the support rod 21 from being separated from the insertion hole 241, and preventing the first assembly tube 11 and the second assembly tube 12 from being separated, thereby improving the connection stability.

[0032] Reference Figure 2 , Figure 4 On the other hand, the screw rod 3 is rotatably inserted in the limiting hole 242. Specifically, a wedge block 31 and a limiting protrusion 32 are arranged on the outer peripheral wall of the screw rod 3. When the screw rod 3 is first inserted into the limiting hole 242, the inner wall of the limiting hole 242 contacts the inclined surface of the wedge block 31, so that the wedge block 31 passes through the limiting hole 242. Afterwards, the opening edge of the limiting hole 242 is inserted between the vertical surface of the wedge block 31 and the side surface of the limiting protrusion 32 to form a clamping structure, so as to realize the rotation of the screw rod 3 and the axial fixation with the spring sheet 24.

[0033] One end of the screw rod 3 is connected to the first assembly tube 11 and the other end is threadedly connected to the bottom wall of the circular groove 121, that is, the fixing plate 23. The center of the end wall of the first assembly tube 11 is provided with an assembly groove 111, which is hexagonal. One end of the screw rod 3 is plugged into the assembly groove 111 to achieve coaxial fixation of the screw rod 3 and the first assembly tube 11, and facilitate the disassembly and assembly of the two. A screw hole 231 is provided through the center of the fixing plate 23, and the screw rod 3 is threadedly connected to the screw hole 231. When the first assembly tube 11 and the second assembly tube 12 rotate relative to each other, the first assembly tube 11 drives the screw rod 3 to rotate, and the screw rod 3 drives the spring plate 24 to approach the fixing plate 23, so that the interlayer space spacing is reduced, and the spring plate 24 and the fixing plate 23 clamp the clamping block 22, thereby improving the connection stability between the first assembly tube 11 and the second assembly tube 12 and reducing the loose phenomenon.

[0034] A guide surface 221 is provided on the side of the clamping block 22 close to the first assembly tube 11, and the guide surface 221 is inclined toward the side away from the support rod 21, so as to guide the clamping block 22 to be inserted into the sandwich between the spring piece 24 and the fixing piece 23. An anti-slip surface 222 is also provided on the side of the clamping block 22 close to the first assembly tube 11. The anti-slip surface 222 can be made of anti-slip texture or frosted. The anti-slip surface 222 is located between the guide surface 221 and the support rod 21 and is parallel to the cross section of the first assembly tube 11. When the first assembly tube 11 and the second assembly tube 12 rotate relatively, the spring piece 24 approaches the anti-slip surface 222 and abuts against it, thereby increasing the friction between the two and preventing the clamping block 22 from loosening.

[0035] The screw rod 3 is provided with limit rings 33 on both sides of the fixing plate 23. The limit rings 33 are sleeved on both sides of the threaded section of the screw rod 3 and are axially fixed to the screw rod 3. The spacing between the two limit rings 33 is greater than the thickness of the fixing plate 23, so that the screw rod 3 and the fixing plate 23 can move relative to each other, and the staff can manually adjust the screw rod 3 so that the screw rod 3 returns to the initial position, which is convenient for adjustment. The limit rings 33 can also limit the range of movement of the screw rod 3 to prevent the screw rod 3 from falling off or getting stuck.

[0036] A plurality of threaded holes (not shown in the figure) are provided at equal intervals along the axial direction on the first assembly tube 11 and the second assembly tube 12, and hooks (not shown in the figure) are threaded through the threaded holes. One end of the hook is bent upward and is used to hang tools such as wrenches and screwdrivers, so that construction workers can place or take tools conveniently, thereby adding new functional attributes and improving practicality.

[0037] The implementation principle of the multifunctional scaffold for construction engineering of the present application embodiment is as follows: during installation, the screw rod 3 is first controlled to make the screw rod 3 away from the limiting ring 33 on one side of the first assembly tube 11 and contact the fixing plate 23 to achieve the reset of the screw rod 3. Then the first assembly tube 11 and the second assembly tube 12 are brought closer to each other, so that the support rod 21 is inserted into the insertion hole 241, and the clamping block 22 enters the circular groove 121. When the first assembly tube 11 and the second assembly tube 12 rotate relative to each other, the clamping block 22 enters the interlayer of the fixing plate 23 and the spring plate 24, and is clamped and matched with the circular groove 121, so that the first assembly tube 11 and the second assembly tube 12 will not separate when subjected to axial force.

[0038] When the first assembly tube 11 and the second assembly tube 12 rotate relative to each other, the first assembly tube 11 drives the screw rod 3 to rotate synchronously, drives the spring sheet 24 to approach the fixing sheet 23, and presses the clamping block 22. Then, the stud 123 is rotated so that its end enters the circular groove 121 and reaches the movement path of the clamping block 22, thereby hindering the reset of the clamping block 22, thereby preventing the clamping block 22 from escaping from the circular groove 121, thereby improving the connection strength between the first assembly tube 11 and the second assembly tube 12.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
