Description

Technical Field

[0001] This utility model belongs to the field of scaffolding technology, specifically relating to an adjustable height disc-lock scaffolding upright. Background Technology

[0002] Scaffolding refers to various supporting structures erected on construction sites to facilitate worker operations and vertical and horizontal transportation. It's a common term in the construction industry, referring to scaffolding used on construction sites for exterior walls, interior decoration, or areas with high ceilings where direct construction is impossible. Its main purpose is for workers to move up and down, for external safety netting, and for installing components at heights; simply put, it's setting up a frame. Scaffolding materials typically include bamboo, wood, steel pipes, or composite materials. In some projects, scaffolding is also used as formwork. Furthermore, it's widely used in advertising, municipal engineering, transportation and bridge construction, and mining. Scaffolding is divided into integrated and modular types. Integrated scaffolding is often used for indoor construction or work on low walls, especially for applying paint to exterior walls.

[0003] Currently, existing scaffolding only uses support poles for support. However, on smooth surfaces such as ceramic tiles, the contact area and friction at the bottom of the support poles are small, making the scaffolding prone to slipping during use. This slipping can scratch the ground, resulting in poor stability of the scaffolding. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an adjustable height disc-lock scaffolding upright. This adjustable height disc-lock scaffolding upright aims to solve the technical problems of small contact area and friction at the bottom of the support pole under existing technologies, which makes the scaffolding prone to slippage during use and scratches the ground during the slippage process, resulting in poor stability of the scaffolding.

[0006] (2) Technical solution

[0007] To solve the above-mentioned technical problems, this utility model provides an adjustable height disc-lock scaffolding upright. The adjustable height disc-lock scaffolding upright includes an anti-slip base and a scaffolding upright body disposed above the anti-slip base. The top of the anti-slip base is fixed with a mounting seat that connects to the scaffolding upright body. The side wall of the mounting seat is fixed with a protrusion. A piston is slidably inserted into the protrusion, and a pressing block is slidably inserted into the top of the protrusion. The top of the piston is elastically provided with a positioning block that engages with the protrusion. The bottom end of the anti-slip base has a negative pressure chamber, and the bottom end of the mounting seat has an air extraction hole that communicates with the negative pressure chamber and the piston respectively.

[0008] When using this technical solution, an anti-slip base is installed at the bottom of the scaffold upright body. Connecting bolts pass through through holes and are connected to nuts, thus fixing the scaffold upright body at the top of the mounting base. During use, the handle moves the lever to retract the piston. The elastic plate in the groove at the top of the piston pushes the positioning block into the positioning groove and keeps it fixed. During the retraction process, the piston draws out the air from the negative pressure chamber, causing the anti-slip base to adhere to the ground and become fixed, improving the stability of the scaffold during use. A pressing block protrudes from the top of the protrusion and slides into the positioning groove. Pushing the pressing block pushes its bottom end out of the positioning groove, causing the piston to return to its original position. During the return process, air is squeezed into the negative pressure chamber, separating the anti-slip base from the ground, improving the ease of separation. The fastening bolts are threaded into screw holes at different positions, allowing adjustment of the connection position between the adjusting rod and the upright body, improving the ease of adjusting the scaffold height.

[0009] Preferably, the top of the mounting base has a mounting hole for accommodating the main body of the scaffold upright, and the side wall of the mounting base has a through hole penetrating the main body of the scaffold upright.

[0010] Furthermore, a rigid support plate for supporting the main body of the scaffold upright is fixed to the bottom wall of the mounting hole, and a connecting bolt is inserted into the through hole, with a nut threaded onto one end of the connecting bolt that passes through the through hole.

[0011] Furthermore, an adjusting rod is slidably inserted into the top of the scaffold upright body, and screw holes are equally spaced on the side wall of the adjusting rod. Fastening bolts with threads inserted into the screw holes are installed on the side wall of the scaffold upright body.

[0012] Furthermore, the inner wall of the protrusion is provided with a positioning groove, and the bottom end of the extrusion block is slidably inserted into the positioning groove.

[0013] Furthermore, the piston has a mounting groove at its top end, the bottom end of the positioning block is slidably inserted into the mounting groove, and the top end of the positioning block is fitted into the positioning groove. An elastic plate is embedded in the mounting groove.

[0014] Furthermore, a pull rod is fixed to the side wall of the piston, and a handle is fixedly installed at one end of the pull rod that passes through the protrusion.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model features an anti-slip base installed at the bottom of the scaffold upright body. Connecting bolts pass through through holes and are connected to nuts, thus keeping the scaffold upright body fixed at the top of the mounting base. During use, the handle is used to pull the rod to retract the piston. The elastic plate in the mounting groove at the top of the piston pushes the positioning block into the positioning groove to keep it fixed. During the retraction process, the piston draws out the air from the negative pressure chamber, causing the anti-slip base to adhere to the ground and be fixed, thereby improving the stability of the scaffold during use.

[0018] By protruding a squeezing block that slides into the positioning groove at the top of the protrusion, pushing the squeezing block causes its bottom end to push the positioning block out of the positioning groove, and after pushing it out, the piston returns to its original position. During the return process, air is squeezed into the negative pressure chamber, thereby separating the anti-slip base from the ground, which improves the ease of separation of the anti-slip base from the ground. By fastening the bolts into the screw holes at different positions, the connection position between the adjusting rod and the main body of the column can be adjusted, which improves the ease of adjusting the height of the scaffold.

A piston 16 is slidably inserted into the protrusion 4, and a pressing block 14 is slidably inserted into the top of the protrusion 4. The top of the piston 16 is elastically provided with a positioning block 19 that engages with the protrusion 4. The bottom end of the anti-slip base 1 is provided with a negative pressure chamber 10, and the bottom end of the mounting seat 2 is provided with an air extraction hole 13 that communicates with the negative pressure chamber 10 and the piston 16 respectively.

[0027] The top of the mounting base 2 has a mounting hole 8 for accommodating the main body 3 of the scaffold upright, and the side wall of the mounting base 2 has a through hole 9 that passes through the main body 3 of the scaffold upright. The bottom wall of the mounting hole 8 is fixed with a rigid support plate 12 for supporting the main body 3 of the scaffold upright. A connecting bolt 7 is inserted into the through hole 9, and a nut 6 is threaded onto one end of the connecting bolt 7 that passes through the through hole 9. An adjusting rod 20 is slidably inserted into the top of the main body 3 of the scaffold upright. The side wall of the adjusting rod 20 has screw holes 21 equidistantly opened, and a fastening bolt 22 is installed on the side wall of the main body 3 of the scaffold upright and threaded into the screw holes 21. The fastening bolt 22 is threaded into the screw holes 21 at different positions, thereby adjusting the connection position between the adjusting rod 20 and the main body of the upright, improving the convenience of adjusting the height of the scaffold. After the connecting bolt 7 passes through the through hole 9, it is connected to the nut 6, thereby keeping the main body 3 of the scaffold upright fixed at the top of the mounting base 2.

[0028] like Figure 3 and Figure 4As shown, a positioning groove 15 is provided on the inner wall of the protrusion 4.
