Description

Technical Field

[0001] The utility model relates to a safety clamp, in particular to a progressive safety clamp which is easy to debug and belongs to the technical field of progressive safety clamps. Background Art

[0002] Progressive safety clamps, also known as progressive safety clamps or step-locking clamps, are tools used to secure parts during machining, assembly or welding. This clamp has a unique design that can be adjusted and adapted to workpieces of different sizes and shapes through multiple locking positions that gradually increase. The gripping force can be increased accordingly as the load gradually increases, ensuring that the clamped object will not fall off even when subjected to vibration or pulling forces in different directions. Progressive safety clamps are made of high-strength materials such as carbon steel or alloy steel, which can not only ensure strong clamping, but also resist corrosion and wear in harsh working environments.

[0003] Authorization announcement number (CN220264838U) discloses a progressive safety clamp that is easy to debug, including a safety clamp fixing frame, a downward pressing fixing mechanism is arranged on the top of the safety clamp fixing frame, and stabilizing frames are arranged on both sides of the safety clamp fixing frame. The inner side of the stabilizing frame penetrates the safety clamp fixing frame and extends to the inside of the safety clamp fixing frame and is movably connected with a positioning clamp, and the bottom of the safety clamp fixing frame is movably connected with a cross plate, and a transmission mechanism is arranged inside the stabilizing frame. The downward pressing fixing mechanism includes a screw, and the screw is arranged on the top of the safety clamp fixing frame. The utility model can limit the back clamp parts of the elevator by the downward pressing fixing mechanism and the cross plate, and then the transmission mechanism can control the movement of a single positioning clamp, so that the user can control the movement of a single clamp when using it, and can control the clamp clamping position, which is convenient for the user to control the clamp clamping position;

[0004] However, the above technology may not be easy to install or disassemble during use, and workers will spend more time and effort when replacing or adjusting workpieces, resulting in reduced production efficiency. In addition, if it is difficult to disassemble, the clamp will be difficult to clean and maintain, which may cause premature wear or failure of the tool. At the same time, a design that is not easy to disassemble may mean that the clamp is difficult to adapt to changing working environments and different workpiece requirements, limiting its wide application.

[0005] Therefore, a progressive safety clamp which is easy to debug is proposed. Utility Model Content

[0031] By setting up the disassembly and assembly mechanism 4, the adaptability and versatility are increased to adapt to workpieces of different sizes and shapes, thereby improving work efficiency and reducing the need to replace different tools. At the same time, it is convenient for users to quickly clean, maintain or replace parts of the pliers to extend the service life of the tool and maintain good working performance.

[0032] Example 2

[0033] In one embodiment, the rotating shaft 301 is movably connected to the rear side of the shell 1, the knob 309 is fixedly connected to the rear end of the rotating shaft 301, the transmission gear 302 is fixedly connected to the front end of the rotating shaft 301, the bidirectional thread 303 is movably connected in the inner cavity of the shell 1, the driven gear 304 is fixedly connected to the surface of the bidirectional thread 303, the driven gear 304 and the surface of the transmission gear 302 are connected by tooth meshing, the threaded sleeve 305 is threadedly connected to the left and right sides of the surface of the bidirectional thread 303, the connecting rod 306 is fixedly connected to the bottom of the threaded sleeve 305, the fixing plate 307 is fixedly connected to the lower end of the connecting rod 306, and the clamp 308 is fixedly connected to the inner side of the fixing plate 307.

[0034] By setting the adjustment mechanism 3, the pressure of the jaws can be adjusted according to the size and shape of the workpiece to ensure the stability of the workpiece, thereby avoiding sliding or falling and improving work safety. At the same time, once the appropriate clamping force is set, the clamp can maintain a constant pressure without the user having to apply continuous force, reducing user fatigue and allowing them to focus on precise operations.

[0035] Example 3

[0036] In one embodiment, sliding rods 5 are fixedly connected to the front and rear sides of the surface of the threaded sleeve 305, sliding grooves 6 are opened on the front and rear sides of the inner cavity of the shell 1, and the sliding rod 5 is slidably connected in the inner cavity of the sliding groove 6.

[0037] The setting of the slide rod 5 and the slide groove 6 can play a guiding role to prevent the threaded sleeve 305 from deflecting during movement.

[0038] When the utility model is in operation: by manually turning the knob 309, the rotating shaft 301 is driven to rotate, and the rotation of the rotating shaft 301 can drive the transmission gear 302 to rotate. When the transmission gear 302 rotates, the driven gear 304 is driven to rotate through the meshing of the teeth. The rotation of the driven gear 304 can drive the two-way thread 303 to rotate. When the two-way thread 303 rotates, the threaded sleeve 305 moves inward. Through the movement of the threaded sleeve 305, the connecting rod 306, the fixing plate 307 and the clamp 308 can be driven to move inward, thereby completing the clamping. When disassembly is required, the pull ring 405 is pulled outward to drive the pull rod 404 to move outward. Through the movement of the pull rod 404, the partition 402 can be driven to move outward. When the partition 402 moves, it will drive the positioning rod 406 to move outward, so that the positioning rod 406 is separated from the slot at the installation position, and the disassembly is completed.

[0039] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
