Description

Technical Field

[0001] This utility model relates to a safety locking pin, specifically a safety locking pin for scaffolding, and belongs to the field of scaffolding technology. Background Technology

[0002] Metal products are various products made from metal materials through processing and manufacturing. Common metal materials include iron, aluminum, copper, and zinc. Metal products are broadly classified into structural metal products and metal tool products. Metal products are widely used in industries such as machinery manufacturing, construction, transportation, and electronics.

[0003] During scaffolding assembly, to maintain overall stability and prevent displacement or collapse under load or external forces, scaffolding locking pins connect and secure the various components of the scaffolding through a fastening action, ensuring the stability of the overall structure and thus protecting the safety of construction workers.

[0004] Most existing scaffolding locking pins consist of a pin and a locking plate. By creating a sliding track inside the locking plate, it can be moved. Moving the locking plate allows it to rotate, keeping it horizontal with the pin. Then, the diagonal brace to be connected is joined to the locking pin. Moving the locking plate again brings it to a vertical position, where it blocks the diagonal brace from being connected to the locking pin. While this structure can connect and position diagonal braces on the scaffolding, connecting them requires first moving the locking plate to a horizontal position with the locking pin. This can cause wobbling during scaffolding assembly, potentially shifting the locking plate and preventing the diagonal brace from connecting, thus reducing assembly efficiency. Therefore, we provide a safety locking pin for scaffolding to solve these problems. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a safety locking pin for scaffolding, with the specific technical solution as follows:

[0006] A safety locking pin for scaffolding includes a locking rod and a locking plate.

A slide rail is formed on the inner side of the locking plate, and a slide block is slidably connected to the inner wall of the slide rail. A spring is disposed inside the locking plate. The inner wall of the slide block is rotatably connected to the outer surface of the support shaft. One end of the locking plate is connected to a base, and a rotating shaft is connected to the inner wall of the base. A positioning roller is rotatably connected to the outer surface of the rotating shaft. A positioning block is connected to the inner wall of the movable groove, and a positioning groove is formed on the inner side of the positioning block, the positioning groove being adapted to the positioning roller.

[0007] Preferably, the outer surface of the slide is connected to two baffles, and the two baffles are symmetrical to each other, and the outer surface of the baffles slides in contact with the outer surface of the slide.

[0008] Preferably, the slide block has two sets of guide rods connected to its side, and the two sets of guide rods are symmetrical, with the outer surface of the guide rods slidably connected to the inner wall of the slide block.

[0023] The present invention will now be further described with reference to the accompanying drawings.

[0024] Please see Figures 1-6 A safety locking pin for scaffolding includes a locking rod 1 and a locking plate 2. The inner side of the locking rod 1 has a moving groove 3, and the locking plate 1 is disposed inside the moving groove 3. The moving groove 3 provides space for the locking plate 2 to move. The inner wall of the locking rod 1 is connected to a support shaft 4. The inner side of the locking plate 2 has a slide rail 5, and the inner wall of the slide rail 5 is slidably connected to a slide block 6. A spring 7 is disposed inside the locking plate 2. The inner wall of the slide block 6 is rotatably connected to the outer surface of the support shaft 4. The support shaft 4 provides support for the slide block 6 and maintains the stability of the slide block 6 during rotation. The slide rail 5 enables the locking plate 2 to move. The position of the positioning roller 10 is changed by the movement of the locking plate 2. After the locking plate 2 moves, the spring 7 is compressed. The compressed spring 7 provides power for the locking plate 2 to reset.

[0025] One end of the locking plate 2 is connected to a base 8, and the inner wall of the base 8 is connected to a rotating shaft 9. The outer surface of the rotating shaft 9 is rotatably connected to a positioning roller 10. The base 8 provides support for the rotating shaft 9 to maintain the stability of the rotating shaft 9, and the rotating shaft 9 provides support for the positioning roller 10 to maintain the stability of the positioning roller 10. The inner wall of the moving groove 3 is connected to a positioning block 11. The inner side of the positioning block 11 is provided with a positioning groove 12, which is adapted to the positioning roller 10. The positioning roller 10 is accommodated by the positioning groove 12, and the movement position of the positioning roller 10 is restricted.

[0026] Two baffles 13 are connected to the outer surface of the slide block 6, and the two baffles 13 are symmetrical. The outer surface of the baffles 13 slides in contact with the outer surface of the slide block 6. The baffles 13 act as a shield outside the slide track 5 to prevent external dust or debris from entering the slide track 5 and contaminating it. When the slide track 5 is contaminated by dust or debris, it will increase the resistance of the slide block 6 and reduce the mobility of the slide block 6. The baffles 13 improve the cleanliness of the inside of the slide track 5.

[0027] The slide block 6 has two sets of guide rods 14 connected to its side, and the two sets of guide rods 14 are symmetrical. The outer surface of the guide rods 14 is slidably connected to the inner wall of the slide block 6. There are four guide rods 14 in one set, and the four guide rods 14 are arranged in a rectangular array. The connection between the guide rods 14 and the locking piece 2 can also guide the movement direction of the slide block 6, thereby maintaining the stability of the slide block 6 when it moves.

[0028] Spring 7 is sleeved on the outside of guide rod 14. One end of spring 7 is connected to the side of slide 6, and the other end of spring 7 is connected to the inner wall of slide 5. The guide rod 14 supports spring 7. When slide 6 moves, spring 7 is compressed and deformed. To prevent spring 7 from deforming too much and losing its elastic support to slide 6, the guide rod 14 supports spring 7 from the inside to maintain the stability of spring 7 during elastic contraction.

[0029] The inner wall of the slide 5 is connected to the guide rail 15, and the inner side of the slide 6 is provided with a slide groove 16. The inner wall of the slide groove 16 is slidably connected to the outer surface of the guide rail 15. The slide 6 contacts the guide rail 15 through the slide groove 16, and the guide rail 15 guides the slide groove 16 to further improve the stability of the slide 6.

[0030] The other end of the locking plate 2 is connected to a counterweight 17, and the diameter of the counterweight 17 is smaller than the diameter of the locking rod 1. The counterweight 17 increases the weight of the other end of the locking plate 2, so that the locking plate 2 is in a vertical state when there is no external force to move it, thereby reducing the movement of the locking plate 2 and changing its angle.

[0031] In use, this invention works as follows: First, the locking piece 2 is moved to the same horizontal level as the locking rod 1. After the locking piece 2 moves to the correct position, it drives the slide block 6 to rotate. Then, the positioning roller 10 contacts the positioning block 11. A pushing force is then applied to the locking piece 2, and the positioning roller 10 enters the positioning groove 12. Simultaneously, the positioning block 11 provides resistance to the positioning roller 10. The positioning roller 10 pushes the base 8 to move via the rotating shaft 9. The base 8 then pushes the locking piece 2 to move. Simultaneously, the locking piece 2 compresses the spring 7 while moving. After the positioning roller 10 enters the positioning groove 12, the spring 7 pushes the locking plate 2 to reset. At the same time, the locking plate 2 moves its position through the base 8 and the rotating shaft 9. The rotating shaft 9 pushes the positioning roller 10 to move its position. Then, the positioning roller 10 keeps in close contact with the positioning groove 12 under the push of the spring 7. Then, the inclined rod and the locking rod 1 can be connected together. Then, a pushing force is applied to the locking plate 2 to push the positioning roller 10 out of the positioning groove 12. Under the drive of the counterweight 17, the locking plate 2 is in a vertical state. After the locking plate 2 is in a vertical state, it blocks the inclined rod and prevents the inclined rod from detaching from the locking rod 1.
