Description

Technical Field

[0001] The utility model relates to a connecting device, in particular to a connecting device for a scaffold, and belongs to the technical field of scaffold connecting components. Background Technique

[0002] A scaffold refers to various supports erected at a construction site for workers to operate and solve vertical and horizontal transportation. It is a general term in the construction industry and is used in places such as the exterior walls of construction sites, interior decoration, or where the floor height is too high to construct directly. It is mainly for construction workers to work up and down, enclose the safety net on the periphery, and install components at high altitudes. A connecting device is needed for the connection of the scaffold.

[0003] Among them, the "scaffold connecting device" disclosed in the patent application number "202320368568.3" "comprises a housing, and a set of second through holes are respectively opened on the left and right sides of the housing. A cross bar is connected through the interior of the second through holes. One end of the cross bar is connected with a positioning plate, and a set of third through holes are correspondingly opened on the two side arms of the positioning plate. An installation block is connected to the inner side of the positioning plate, the installation block is fixedly connected with the housing, and a clamping groove is opened at a position close to the third through hole inside the installation block." In the present utility model, a base, a clamping groove, a compression spring, a connecting rod, and an installation block are provided. When the cross bar needs to be connected, the upper and lower pull rings are lifted simultaneously, driving the connecting rod, the base, and the positioning block to rise, taking out the positioning block from the inside of the clamping groove, and then inserting the cross bar into the housing, so that the positioning plate at one end of the cross bar is stuck on the convex block on the outer surface of the installation block. Then, the pull rings are released, and under the elastic action of the compression spring, the base and the positioning block are reset, and then the positioning block is inserted into the positioning plate and the clamping groove to complete the fixed connection of the cross bar. When the cross bar needs to be taken out, only the upper and lower pull rings need to be lifted again, and the cross bar is taken out from the positioning plate and the clamping groove to complete the disassembly.

[0004] However, the above method still has the following defects: By pulling the two pull rings and cooperating with the separation of the positioning block and the positioning groove to achieve the disassembly and assembly of the cross bar, but in the process of pulling the pull rings, the current design requires both hands to operate synchronously, lacking an effective limiting mechanism for the pull rings, making the disassembly work of the cross bar have to rely on multi-person cooperation, increasing the complexity of the operation process, and thus affecting the overall construction efficiency. Content of the Utility Model

[0005] The purpose of the present utility model is to provide a scaffold connecting device to solve the problem that pulling the pull rings requires both hands to operate synchronously, lacking effective limiting, resulting in the need for multi-person cooperation for the disassembly of the cross bar, increasing the operation complexity, and affecting the construction efficiency as mentioned in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A scaffolding connection device includes a fixed box.

[0008] As a preferred technical solution of the present utility model, a guiding rod is slidably arranged in the middle of the insertion block, and one end of the guiding rod is fixedly connected with the inner wall of the fixed box.

[0009] As a preferred technical solution of the present utility model, a first spring is sleeved on the outside of the guiding rod. One end of the first spring is fixedly connected with the middle of one side of the insertion block, and the other end is fixedly connected with the inner wall of the fixed box.

[0010] As a preferred technical solution of the present utility model, a rotating cap is provided at the top end of the circular plate, and anti-slip convex columns are provided on the surface of the rotating cap.

[0011] As a preferred technical solution of the present utility model, the rotating rod is rotatably connected with the fixed box through a bearing.

[0012] As a preferred technical solution of the present utility model, the limit component includes a fixed shell. The fixed shell is fixedly installed on one side of the top end of the fixed box.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-6 , the present invention provides a scaffolding connection device, which includes a fixed box 1. Both sides of the fixed box 1 are slidably provided with cross bars 3 through two sliders 2. The cross bar 3 is a part of the support structure in the scaffolding. At the bottom end of the inner wall of the fixed box 1, there is a support block 4. At the top of both sides of the support block 4, there are two cross plates 5. A slide bar 6 is slidably arranged in the middle of the cross plate 5. On one side of the slide bar 6, there is an insertion block 7. On one side of the slider 2, there is a slot which is in plug-in fit with the insertion block 7. On the other side of the slide bar 6, there is a rack plate 8. Between the two rack plates 8, there is a meshing gear 9. By rotating the gear 9, the two meshing and connected rack plates 8 can be driven to move synchronously towards each other, so that the insertion block 7 and the slot at the slider 2 are separated from each other, thereby realizing the disassembly or installation of the cross bar 3. And at the top of the gear 9, there is a rotating rod 10, which is convenient for driving the gear 9 to rotate in the positive and negative directions. The top of the rotating rod 10 penetrates through the fixed box 1 and is provided with a circular plate 14. On both sides of the top end of the fixed box 1, there are limit assemblies 12. Through the limit assemblies 12, the circular plate 14 at the rotating rod 10 can be limited or separated, so that the rotating rod 10 is limited, and then it is convenient to synchronously limit the gear 9 and the rack plate 8.

[0026] A guide rod 13 is slidably arranged in the middle of the insertion block 7, and one end of the guide rod 13 is fixedly connected to the inner wall of the fixed box 1. By arranging the guide rod 13, it is convenient for the insertion block 7 not to be restricted during the movement;

[0027] A first spring 11 is sleeved outside the guide rod 13. One end of the first spring 11 is fixedly connected to the middle of one side of the insertion block 7, and the other end is fixedly connected to the inner wall of the fixed box 1, which is convenient for playing a role of reset support for the insertion block 7, so that the insertion block 7 rebounds by support, and makes the insertion block 7 in close contact with the slot;

[0028] The limit component 12 includes a fixed shell 1201 which is fixedly installed on one side of the top of the fixed box 1. A moving block 1202 is slidably arranged inside the fixed shell 1201. A plug rod 1203 is arranged in the middle of one side of the moving block 1202. Two jacks which are in plug-in fit with the plug rod 1203 are formed on the surface of the circular plate 14. A second spring 1204 is arranged on the other side of the moving block 1202. One end of the second spring 1204 is fixedly connected to the inner wall of the fixed shell 1201. By moving the arranged moving block 1202 to drive the plug rod 1203 to move in the horizontal direction, the mutually inserted plug rod 1203 and the jack can be separated from each other. At the same time, it can cooperate with the second spring 1204 to support and rebound the moving block 1202 and the plug rod 1203, so as to limit the rotation rod 10.

[0029] A moving groove which is in sliding fit with the moving block 1202 is formed at the bottom end of the inner wall of the fixed shell 1201, so that the moving block 1202 is not restricted in the sliding process. A pull column 1205 is arranged at the top end of the moving block 1202, and an anti-slip sleeve is sleeved on the surface of the pull column 1205, which is convenient to drive the moving block 1202 to move horizontally through the pull column 1205 and plays an anti-slip role during stretching.

[0030] A rotating cap 15 is arranged at the top end of the circular plate 14, and anti-slip convex columns are arranged on the surface of the rotating cap 15. By cooperating the rotating cap 15 with a plurality of anti-slip convex columns, an anti-slip effect can be achieved during the rotation of the rotating rod 10, so that the rotating rod 10 rotates easily.

[0031] The rotating rod 10 is rotatably connected to the fixed box 1 through a bearing, which is convenient to support and rotate the rotating rod 10, and the use convenience is good.

[0032] Both sides of the two support blocks 4 are in contact with one end of the cross bar 3, which is convenient to limit the cross bar 3 and remind the staff that the cross bar 3 is inserted into the fixed box 1 completely. Sliding grooves which are in sliding fit with the slider 2 are formed on both sides of the fixed box 1, so that the slider 2 is not restricted in the sliding process.

[0033] In use, first place the scaffolding connecting device at a suitable position, that is, ensure that the fixed box 1 is placed at a proper working location. Then drive the moving block 1202 to move horizontally inside the fixed housing 1201 through the pulling column 1205. At this time, the second spring 1204 is compressed, and the set inserting rod 1203 is separated from the jack. Immediately afterwards, drive the circular plate 14, the rotating rod 10, and the gear 9 to rotate synchronously through the rotating cap 15. After the rotation ends, release the set pulling column 1205. Under the support and rebound of the second spring 1204, the moving block 1202 is supported and reset. At this time, the inserting rod 1203 is inserted into another jack, thereby realizing the limitation of the circular plate 14. During the process of driving the gear 9 to rotate by the rotating rod 10, cooperating with the meshing set rack plate 8, the two rack plates 8 move towards each other synchronously, and further the two sliding strips 6 and the two inserting blocks 7 move towards each other synchronously. At this time, the cross bar 3 with the slider 2 is inserted into the fixed box 1, and its end is mutually attached to the support block 4. At this time, the first spring 11 is in a compressed state. Immediately afterwards, stretch the set pulling column 1205 again, drive the moving block 1202 to move again inside the fixed housing 1201, so that the inserting rod 1203 is separated from the jack again. At this time, under the support and rebound of the first spring 11, the two inserting blocks 7 move closer to each other and are inserted into the slots at the slider 2. Release the pulling column 1205 to limit the inserting rod 1203 at the jack, and complete the installation and fixation of the cross bar 3;

[0034] Subsequently, another cross bar 3 can be installed with the scaffolding connecting device by repeating the above steps, so that the construction workers do not need to operate both hands synchronously, can disassemble and assemble the cross bar 3, and realize single-person operation during the disassembly and assembly of the cross bar 3, improving work efficiency.
