Abstract

This utility model discloses a self-locking scaffold board, including a board body. Mounting plates are located at the four corners of the board body. Hooks are mounted on the edges of the mounting plates, and horizontal shafts are mounted on the hooks. Limit hooks are located on the outer sides of the hooks, and the limit hooks are connected to the hooks via the horizontal shafts. A groove is formed on the limit hook, and a pin is located on the inner side of the groove. A drive rod is mounted on the pin, and a sleeve is located on the outer side of the drive rod. A tensioning spring is located inside the sleeve. This self-locking scaffold board allows the board body to be placed on the scaffold via the hooks. When the hooks are placed on the scaffold, the tensioning spring pushes the drive rod to extend from the sleeve. The drive rod, through the cooperation between the pin and the groove, pushes the limit hook to rotate via the horizontal shaft. This facilitates the locking and clamping of the limit hook and hook onto the scaffold, improving the stability of the board.

Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, specifically a self-locking scaffolding board. Background Technology

[0002] Scaffold boards, also known as scaffold planks, are temporary building materials laid on scaffolds and work platforms to facilitate workers' walking, material transport, and construction operations.

[0003] Currently, scaffold boards on the market are equipped with fixing clips, which are used to directly attach them to the horizontal and vertical bars of the scaffolding. When construction workers step on a corner, the boards can easily lift up, posing a certain safety hazard. To address these issues, an innovative design has been developed based on the existing scaffold boards. Utility Model Content

[0004] The purpose of this utility model is to provide a self-locking scaffold board to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-locking scaffold board, comprising a board body, mounting plates respectively provided at the four corners of the board body, hooks installed on the edges of the mounting plates, horizontal shafts installed on the hooks, limit hooks provided on the outer side of the hooks, the limit hooks being connected to the hooks via the horizontal shafts, grooves provided on the limit hooks, pins provided on the inner side of the grooves, a drive rod installed on the pins, a sleeve provided on the outer side of the drive rod, and a tensioning spring provided inside the sleeve.

[0006] Preferably, the mounting plate and the hook are designed as a single unit.

[0007] Preferably, the limiting hook is rotatably connected to the hook via a horizontal shaft.

[0008] Preferably, the pin is slidably connected to the limiting hook via a groove rail, and the pin is fixedly connected to the drive rod.

[0009] Preferably, the sleeve is fixed to the surface of the mounting plate, and the drive rod forms a telescopic structure with the sleeve through a clamping spring.

[0010] Preferably, the mounting plate is provided with multiple fixing holes, and the mounting plate is fixed to the four corner sidewalls of the plate body by bolts passing through the fixing holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the self-locking scaffold board can be attached to the scaffold by hooks. After the hooks are attached to the scaffold, the top spring can push the drive rod to extend out of the sleeve rod. The drive rod then pushes the limit hook to rotate through the horizontal axis through the cooperation between the pin and the groove rail. This facilitates the cooperation between the limit hook and the hook to lock and grab onto the scaffold, thereby improving the stability of the board placement. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 This utility model provides a self-locking scaffold board, including a board body 1. Mounting plates 2 are respectively provided at the four corners of the board body 1. Hooks 3 are installed on the edges of the mounting plates 2. A horizontal shaft 4 is installed on the hooks 3. A limit hook 5 is provided on the outer side of the hooks 3. The limit hook 5 is connected to the hooks 3 through the horizontal shaft 4. A groove 6 is provided on the limit hook 5. A pin 7 is provided on the inner side of the groove 6. A drive rod 8 is installed on the pin 7. A sleeve 9 is provided on the outer side of the drive rod 8. A tightening spring 10 is provided inside the sleeve 9.

[0019] In one or more embodiments of this utility model, the mounting plate 2 and the hook 3 are designed as a single unit, which improves the structural stability between the mounting plate 2 and the hook 3, and improves the stability of the plate 1 when suspended by the hook 3.

[0020] In one or more embodiments of this utility model, the limiting hook 5 is rotatably connected to the hook 3 via the horizontal shaft 4, which facilitates the adjustment of the angle of the limiting hook 5 on the hook 3 via the horizontal shaft 4, and is beneficial to adjusting the size of the opening between the limiting hook 5 and the hook 3.

[0021] In one or more embodiments of this utility model, the pin 7 is slidably connected to the limiting hook 5 via the groove 6, and the pin 7 is fixedly connected to the drive rod 8. When the drive rod 8 pushes the pin 7 to move, the pin 7 can push the limiting hook 5 to rotate via the groove 6.

[0022] In one or more embodiments of this utility model, the sleeve rod 9 is fixed to the surface of the mounting plate 2, and the drive rod 8 forms a telescopic structure with the sleeve rod 9 through the tightening spring 10, which is beneficial for the tightening spring 10 to push the drive rod 8 to extend and retract within the sleeve rod 9.

[0023] In one or more embodiments of this utility model, the mounting plate 2 is provided with multiple fixing holes, and the mounting plate 2 is connected and fixed to the four peripheral corner sidewalls of the plate body 1 by bolts passing through the fixing holes. The mounting plate 2 can be firmly fixed to the plate body 1 by multiple bolts.

[0024] according to Figures 1-4 As shown, in use, first push the limit hook 5 to rotate on the hook 3 via the horizontal axis 4 until the gap between the limit hook 5 and the hook 3 expands. Then, the plate 1 is placed on the scaffold via the hook 3. After the hook 3 is placed on the scaffold, release the pushed limit hook 5. At this time, the tightening spring 10 can push the drive rod 8 to extend out of the sleeve rod 9. The drive rod 8 then pushes the limit hook 5 to rotate in the opposite direction via the horizontal axis 4 through the cooperation between the pin 7 and the groove rail 6 until the limit hook 5 and the hook 3 cooperate and lock onto the scaffold, improving the stability of the plate 1.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
