Quickly built connecting and locking structure for construction scaffold

Abstract

This utility model discloses a rapid erection, connection, and locking structure for construction scaffolding, relating to the field of scaffolding technology. The utility model includes a column, with a fixing plate fixedly connected to its inner wall. A locking mechanism is also provided on the inner wall of the column. By incorporating a coupling ring, the scaffolding uprights can be inserted through holes in the column surface to pass through the entire column. Turning a knob clockwise rotates a worm gear, which in turn rotates a worm wheel, which in turn rotates the coupling ring. The coupling ring then displaces one end of several coupling rods, causing them to rotate as a whole. Each coupling rod displaces a displacement block, which in turn displaces an anti-slip sleeve. The anti-slip sleeves then move closer together and clamp the uprights to secure the entire structure. This allows for multi-angle clamping of the scaffolding uprights, ensuring that the entire structure will not easily slip or displace due to external forces.

Description

Technical Field

[0001] This utility model belongs to the field of scaffolding technology, and in particular relates to a rapid erection, connection and locking structure for building construction scaffolding. Background Technology

[0002] According to the published patent CN214462481U, a quick-locking connection structure for scaffolding includes a column. The column is hollow and has a through hole in the vertical direction. A worm gear is rotatably connected to the bottom inside the column. The worm gear and worm shaft facilitate the rotation of the worm gear, allowing the clamping block on the worm gear to slide along the groove. At the same time, the clamping block moves radially along the column to clamp the uprights in the scaffolding. The worm gear and worm shaft have a unidirectional transmission characteristic, which helps to ensure that the clamping block does not loosen after clamping the uprights. The groove design on the worm gear facilitates the radial movement of the clamping block towards the worm gear when it rotates, thus clamping the uprights. The design of the connecting block and positioning component facilitates the fixing of the crossbars in the scaffolding. However, the following shortcomings still exist.

[0003] In use, the above-mentioned equipment mainly relies on the clamping block on the worm gear to slide along the slide groove to clamp the uprights of the scaffold. However, in actual situations, the above structure may often cause the clamping block to get stuck during displacement due to uneven sliding, which has certain reliability defects. Therefore, we propose a rapid erection connection and locking structure for construction scaffolding. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-connection and locking structure for building construction scaffolding. Through the locking mechanism and the connecting mechanism, it solves the problem that the scaffolding uprights are mainly clamped by allowing the clamping block on the worm gear to slide along the slide groove. However, in actual situations, the above structure may often cause the clamping block to get stuck during displacement due to uneven sliding, resulting in certain reliability defects.

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

[0006] This utility model is a quick-erecting connection and locking structure for building construction scaffolding, including a column, a fixing plate fixedly connected to the inner wall of the column, and a locking mechanism provided on the inner wall of the column;

[0007] The locking mechanism includes a worm gear, the outer wall of which is rotatably connected to the inner wall of a column. A knob is fixedly connected to the outer wall of the worm gear. A worm wheel is rotatably connected to the inner wall of the column, and the outer wall of the worm wheel meshes with the outer wall of the worm gear. A coupling ring is fixedly connected to the top outer wall of the worm wheel. Several coupling rods are rotatably connected to the outer wall of the coupling ring. Displacement blocks are rotatably connected to the inner walls of the coupling rods. Anti-slip sleeves are fixedly connected to the outer walls of the displacement blocks. A guide plate is fixedly connected to the inner wall of the fixing plate. Several guide grooves are formed on the inner wall of the guide plate, and the inner walls of the guide grooves are slidably connected to the outer walls of the displacement blocks.

[0008] Furthermore, the outer wall of the column is provided with a connecting mechanism, which includes a plurality of connecting blocks. The outer walls of the plurality of connecting blocks are fixedly connected to the outer wall of the column. A sleeve is fixedly connected to the outer wall of the plurality of connecting blocks, and an extension tube is slidably connected to the inner wall of the sleeve.

[0009] Furthermore, a fixing ring is fixedly connected to the outer wall of the extension tube, and a plurality of sliding rods are fixedly connected to the outer wall of the fixing ring.

[0010] Furthermore, a plurality of sliding limit blocks are fixedly connected to the outer wall of the connecting block, and the inner walls of the plurality of sliding limit blocks are slidably connected to the outer wall of the slide rod.

[0011] Furthermore, a plurality of springs are fixedly connected to the outer wall of the fixed ring, and the outer walls of the plurality of springs are all fixedly connected to the outer wall of the sliding limit block.

[0012] Furthermore, a bearing seat is fixedly connected to the outer wall of the slide rod, and several connecting rods are rotatably connected to the inner wall of the bearing seat.

[0013] Furthermore, the inner walls of several of the connecting rods are rotatably connected to lifting blocks, and the outer walls of the lifting blocks are fixedly connected to anti-slip sleeves.

[0014] Furthermore, the inner wall of the connecting block is provided with a plurality of lifting grooves, and the inner walls of the plurality of lifting grooves are slidably connected to the outer walls of the plurality of lifting blocks.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting a coupling ring, allows the uprights of the scaffolding to be inserted through holes in the surface of the column to pass through the entire column. Then, turning the knob clockwise causes the knob to rotate the worm gear, which in turn rotates the worm wheel, which in turn rotates the coupling ring. The coupling ring causes one end of several coupling rods to shift and rotate as a whole. Each coupling rod causes the displacement block to shift, which in turn causes the anti-slip sleeve to shift. The anti-slip sleeves then move closer together and work together to clamp the uprights to fix the entire equipment. This allows for multi-angle clamping of the uprights of the scaffolding, ensuring that the entire equipment will not easily slip or shift due to external forces, effectively improving the stability of the entire equipment after installation.

[0017] 2. This utility model incorporates springs, allowing for the initial pushing of any fixed ring towards the column. The fixed ring then displaces several sliding rods and simultaneously compresses several springs. Each sliding rod displaces the bearing seat, which in turn displaces and rotates several connecting rods. These connecting rods then displace the lifting block, which in turn displaces the anti-slip sleeves. The anti-slip sleeves then move away from each other. Subsequently, the horizontal bar is directly inserted from the fixed ring into the connecting block, and the fixed ring is released. The springs indirectly reset the anti-slip sleeves, enabling a rapid connection between the entire equipment and the scaffold's horizontal bars. The installation process is simple and convenient, significantly improving installation efficiency.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] The outer wall of the column 1 is provided with a connecting mechanism 3, which includes several connecting blocks 301. The outer walls of the connecting blocks 301 are fixedly connected to the outer wall of the column 1. The outer walls of the connecting blocks 301 are fixedly connected to sleeves 302.

[0033] One specific application of this embodiment is:

[0034] When workers need to use the equipment, they can insert the uprights of the scaffolding through the holes on the surface of column 1 to pass through the entire column 1. Then, they can turn the knob 202 clockwise. The knob 202 will drive the worm gear 201 to rotate, which in turn drives the worm wheel 203 to rotate. The worm wheel 203 will drive the coupling ring 204 to rotate, which will cause one end of several coupling rods 205 to move and rotate as a whole. Several coupling rods 205 will drive the displacement block 206 to move, which in turn drives the anti-slip sleeve 207 to move. Several anti-slip sleeves 207 will move closer to each other and cooperate to clamp the uprights to fix the entire equipment. If it is necessary to install the horizontal bars of the scaffolding on the equipment, any fixing ring 304 can be pushed towards column 1. This will cause several sliding rods 305 to shift and simultaneously compress several springs 307. Several sliding rods 305 will cause the bearing seat 308 to shift, the bearing seat 308 will cause several connecting rods 309 to shift and rotate, several connecting rods 309 will cause the lifting block 310 to shift, the lifting block 310 will cause the anti-slip sleeve 311 to shift, and several anti-slip sleeves 311 will move away from each other. Then, the crossbar is directly inserted from the fixing ring 304 into the connecting block 301 and the fixing ring 304 is released. Several springs 307 will indirectly cause several anti-slip sleeves 311 to reset. Several anti-slip sleeves 311 will move closer to each other and cooperate to clamp the crossbar for fixation. During this period, the sleeve 302 and the extension tube 303 will play a certain protective role at the connection.
