Description

Technical Field

[0001] This utility model relates to the field of construction tools technology, and in particular to a variable-direction disc-lock scaffolding top support. Background Technology

[0002] In the construction industry, scaffolding, as a temporary support structure, directly impacts the safety and convenience of construction through the performance of its top support components. Traditional scaffolding top supports often employ fixed structures, which are ill-suited to complex terrain or irregular working surfaces. This necessitates repeated adjustments to the overall scaffolding layout during construction, increasing both construction and time costs. While some adjustable top supports offer angle adjustment capabilities, the adjustment methods are complex, relying on the combination and fixation of multiple disparate components. This not only makes operation cumbersome but also increases the risk of support failure due to component loosening over long-term use, posing significant safety hazards. Furthermore, the existing top support's fastening structure lacks stability and cannot maintain reliable connections under heavy loads, failing to meet the high strength and precision requirements of modern construction projects for scaffolding support systems. Therefore, there is an urgent need for a scaffolding top support that is simple in structure, easy to adjust, and highly stable to overcome the shortcomings of existing technologies. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems by providing a variable-direction disc-lock scaffolding top support.

[0004] The technical solution of this utility model is implemented as follows: This utility model provides a variable-direction disc-lock type scaffolding top support, the scaffolding top support comprising: Scaffolding support poles; A supporting steel plate is installed on the top of the scaffold support rod, and an adjustment groove is also provided on the supporting steel plate; A tray is rotatably mounted on the supporting steel plate; An adjusting screw, one end of which is rotatably connected to the bottom of the support plate, and the other end of which passes through the adjusting groove through the supporting steel plate; The top support further includes fasteners for fixing the relative position between the adjusting screw and the supporting steel plate, thereby fixing the rotation angle of the support plate.

[0005] The advantages or beneficial effects of the above technical solutions include at least the following: This snap-on scaffolding top support significantly improves the flexibility and safety of scaffolding use. The support plate and the supporting steel plate are connected by a pivot pin, and the linkage design of the adjusting screw and adjusting groove allows for flexible multi-angle adjustment of the support plate, easily adapting to the support needs of working surfaces with different inclination angles, greatly expanding the application scenarios of scaffolding. The diverse designs of the fasteners provide flexible options for different construction scenarios: In the first embodiment, the triangular stable structure formed by the first nut and the second nut generates strong friction during tightening, effectively preventing the adjustment screw from moving and the pallet from rotating, ensuring a stable connection even under heavy load conditions; In the second embodiment, the combination design of the adjustment sleeve and the positioning ring makes the pallet angle adjustment operation simpler, and can be quickly achieved with a wrench. At the same time, the positioning ring and the support rod work together to ensure the stability and reliability of the structure during the adjustment process. Furthermore, the hexagonal nut block design at the bottom of the adjusting sleeve further optimizes the ergonomic experience, reduces the operational difficulty for construction workers, and improves construction efficiency. The overall structural design is reasonable, and the components are tightly connected, which not only enhances the load-bearing capacity of the top support but also extends the service life of the scaffolding, providing a safe and efficient support solution for building construction.

[0012] A variable-direction disc-lock scaffolding top support, the scaffolding top support comprising: Scaffolding support pole 10; A support steel plate 20 is installed at the top of the scaffolding support rod 10. An adjustment groove 21 is also provided on the support steel plate 20. The adjustment groove 21 extends a predetermined distance along the length of the support steel plate 20. The pallet 30 is rotatably mounted on the support steel plate 20. Specifically, a pin 22 is mounted on the support steel plate 20, and the pallet 30 is rotatably connected to the support steel plate 20 through the pin 22. The adjusting screw 40 has one end rotatably connected to the bottom of the support plate 30, and the other end passes through the support steel plate 20 via the adjusting groove 21. When the support plate 30 rotates, the part of the adjusting screw 40 in the adjusting groove 21 will also rotate accordingly. Furthermore, the top support also includes a fastener 50, which is used to fix the relative position between the adjusting screw 40 and the support steel plate 20 to fix the rotation angle of the support plate 30. In the first embodiment, as Figure 1 and Figure 2 As shown, fastener 50 includes: The first nut 51 is rotatably mounted on the adjusting screw 40 through a threaded engagement, and the first nut 51 is located on the top of the supporting steel plate 20; The second nut 52 is rotatably mounted on the adjusting screw 40 via a threaded engagement, and the first nut 51 is located at the bottom of the supporting steel plate 20; When it is necessary to rotate the support plate 30, the second nut 52 needs to be rotated and moved downwards first. After rotating the support plate 30, the first nut 51 and the second nut 52 are rotated on the adjusting screw 40 and brought closer to each other until they abut against the support steel plate 20. This fixes the adjusting screw 40 so that it does not move up or down. When the first nut 51 and the second nut 52 are pressed against each other, the friction prevents the adjusting screw 40 from sliding back and forth. This forms a triangular structure between the support plate 30, the support steel plate 20, and the adjusting screw 40, preventing the support plate 30 from rotating and maintaining its angle.

[0013] In the second embodiment, as Figure 4 and Figure 5 As shown, fastener 50 includes: The adjusting sleeve 53 is rotatably fitted onto the adjusting screw 40 via a threaded connection, and the adjusting sleeve 53 can move up and down along the adjusting screw 40 in a rotatable manner; The positioning ring 54 is rotatably installed in the adjusting groove 21 and is rotatably sleeved on the outside of the adjusting sleeve 53 to avoid the positioning ring 54 affecting the rotation of the adjusting sleeve 53. When it is necessary to rotate the support plate 30, the adjusting sleeve 53 can be rotated directly to change the position of the adjusting sleeve 53 on the adjusting screw 40. Since the position of the positioning ring 54 remains unchanged, when the adjusting sleeve 53 is rotated, the adjusting screw 40 will push the support plate 30 upward or pull the support plate 30 downward, and the angle between the adjusting screw 40 and the support plate 30 will also change. A support rod 541 is installed on the outside of the positioning ring 54. One end of the support rod 541 is rotatably connected to the inner wall of the adjusting groove 21, so that the adjusting sleeve 53 adapts to the angle change of the adjusting screw 40.

[0014] Based on the further improvement of the above structure, the bottom of the adjusting sleeve 53 has a hexagonal nut block 531 that is compatible with the wrench, so that the user can rotate the adjusting sleeve 53 with the wrench tool.

[0015] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present invention and are not intended to limit the scope of the present invention.
