Description

Technical Field

[0001] This utility model belongs to the field of carabiner technology, specifically a carabiner self-closing locking device. Background Technology

[0002] Carabiners are connecting rings made of materials such as aluminum alloy and stainless steel. They are mainly used for suspending and safely connecting items in outdoor sports and rock climbing scenarios. Common shapes include D-shape, figure-eight shape, and racetrack shape. They have high strength and load-bearing capacity, and some products are equipped with a locking design to enhance security.

[0003] Meanwhile, a carabiner with announcement number CN218942436U is disclosed, including a carabiner body, a closing actuator, and a faceplate. The carabiner body has a mounting hole and an opening. At the opening, one end of the carabiner body is a contact end, and the other end is a connecting end. The first end of the closing actuator is rotatably connected to the connecting end, and the second end of the closing actuator can abut against the contact end to close the opening or separate from the contact end to open the opening. The faceplate is connected to the carabiner body at the mounting hole. The faceplate and the mounting hole cooperate to form a receiving cavity. The receiving cavity is used to place a locator. The carabiner described above is prone to breakage at the connection point during use, and it is also prone to wear and slippage over time, making it very dangerous to use.

[0004] Therefore, a self-closing locking device for carabiners is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a carabiner self-closing locking device, which has the advantages of enabling the carabiner to close automatically, achieving a self-closing function, being convenient and quick, and improving usage efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a carabiner self-closing locking device, comprising a carabiner body, a fixing plate fixedly disposed inside the carabiner body, a rotating shaft three fixedly disposed on the left side of the fixing plate, a fixing rod rotatably disposed on the left side of the rotating shaft three, a connecting rod fixedly disposed on the left side of the fixing rod, and a cylinder fixedly disposed below the connecting rod.

[0007] Preferably, a damping rod is fixedly provided on the left side of the fixing plate, and the damping rod is fixedly provided with the connecting rod, and a spring is provided on the outside of the damping rod.

[0008] By adopting the above technical solution, the damping rod plays a buffering role, preventing the elastic force of the second spring from being too large and causing the closing process to be too violent, reducing the impact and wear between components, extending the service life of the carabiner, and also ensuring the stability and safety of the closing process.

[0009] Preferably, a spring bracket is fixedly provided inside the connecting column, a support is fixedly provided inside the connecting column, and a spring is provided outside the support, and the spring is fixedly set with the connecting column.

[0010] By adopting the above technical solution, the spring inside the connecting post is fixedly installed with the connecting post and cooperates with the bracket. During the use of the carabiner, the spring can buffer external impact forces to a certain extent. For example, when a climber is climbing or is accidentally pulled, the spring can absorb some energy, reducing the risk of damage to the carabiner body and connecting parts, and protecting the climber's safety.

[0011] Preferably, a button is fixedly provided below the second rotating shaft, and the button is slidably disposed with the carabiner body. A third spring is fixedly provided to the left side of the button, and the third spring is fixedly disposed with the fixing plate.

[0012] By adopting the above technical solution, a button is connected to the lower part of the connecting rod via a connecting bracket and a second rotating shaft. The button is slidably mounted on the carabiner body, and a third spring on the left side of the button is fixed to the fixing plate. The user simply presses the button, and the connecting rod rotates around the third rotating shaft via the second rotating shaft and the connecting bracket, thus opening the carabiner. After releasing the button, the elastic force of the third spring resets the button, and the carabiner automatically closes under the action of the second spring. The operation is simple and easy to understand, allowing for quick opening and closing even in emergency or complex situations.

[0013] Preferably, a connecting frame is fixedly provided below the connecting rod, and a rotating shaft is rotatably provided below the connecting frame.

[0014] By adopting the above technical solution, springs one, two, and three work together to ensure the normal operation of the carabiner. Spring two enables the self-closing function, spring one buffers impact force, and spring three assists in button reset. The coordinated work of multiple springs allows the carabiner to maintain good performance in different usage scenarios, improving its adaptability and reliability.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a damping rod on the left side of the fixed plate to fix the connecting rod, and a second spring is provided on the outside of the damping rod. When the carabiner is closed, the second spring is compressed and stores elastic potential energy. After the external force is released, the compressed energy of the second spring pushes the connecting rod to drive the fixed rod to rotate around the third pivot, thereby making the carabiner automatically close, realizing the self-closing function, which is convenient, quick and improves the efficiency of use.

[0016] 2. This utility model connects a button to the carabiner body via a connecting frame and a second rotating shaft below the connecting rod. The button is slidably mounted on the carabiner body, and a third spring on the left side of the button is fixed to a fixing plate. The user simply presses the button, and the connecting rod rotates around the third rotating shaft via the second rotating shaft and the connecting frame, thus opening the carabiner. Releasing the button causes the button to reset due to the elastic force of the third spring, and the carabiner automatically closes under the action of the second spring. The operation is simple and easy to understand, allowing for quick opening and closing even in emergency or complex situations. Attached Figure Description

[0019] 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.

[0020] The following describes an embodiment of this utility model based on its overall structure.

[0021] like Figures 1 to 4 As shown, this utility model provides a carabiner self-closing locking device, including a carabiner body 1, a fixing plate 15 fixedly disposed inside the carabiner body 1, a rotating shaft 18 fixedly disposed on the left side of the fixing plate 15, a fixing rod 17 rotatably disposed on the left side of the rotating shaft 18, a connecting rod 9 fixedly disposed on the left side of the fixing rod 17, and a cylinder 8 fixedly disposed below the connecting rod 9.

[0022] In this embodiment, a damping rod 12 is fixedly provided on the left side of the fixing plate 15, and the damping rod 12 is fixedly set with the connecting rod 9. A second spring 13 is provided on the outside of the damping rod 12. The damping rod 12 plays a buffering role, avoiding excessive elastic force of the second spring 13 from causing the closing process to be too violent, reducing the impact and wear between components, extending the service life of the carabiner, and also ensuring the stability and safety of the closing process. A connecting frame 10 is fixedly provided below the connecting rod 9, and a rotating shaft 11 is rotatably provided below the connecting frame 10. The first spring 6, the second spring 13, and the third spring 16 cooperate with each other to ensure the normal operation of the carabiner. Spring 2 (13) enables self-closing, spring 1 (6) buffers impact, and spring 3 (16) assists in resetting button 19. The coordinated operation of multiple springs ensures the carabiner maintains good performance in various usage scenarios, improving its adaptability and reliability. Button 19 is fixedly located below pivot 2 (11) and slides with the carabiner body 1. Spring 3 (16) is fixedly located to the left of button 19 and is fixed to the fixing plate 15. Button 19 is connected to connecting rod 9 via connecting bracket 10 and pivot 2 (11). Button 19 slides with the carabiner body 1, and spring 3 (16) to the left of button 19 is fixed to the fixing plate 15. The user simply presses button 19, which, through the transmission of pivot 2 (11) and connecting bracket 10, causes connecting rod 9 to rotate around pivot 3 (18), thus opening the carabiner. After releasing button 19, the elastic force of spring 16 resets button 19, and the carabiner automatically closes under the action of spring 13. The operation is simple and easy to understand, allowing for quick opening and closing even in emergency or complex situations. A pivot 2 is fixedly mounted on the top of the carabiner body 1. A connecting post 3 is rotatably mounted on the outside of pivot 2. A spring bracket 5 is fixedly mounted inside the connecting post 3, and a bracket 4 is fixedly mounted inside the connecting post 3. A spring 6 is fixedly mounted on the outside of bracket 4, and spring 6 is fixedly mounted to the connecting post 3. Spring 6 inside the connecting post 3 is also fixedly mounted to the connecting post 3 and cooperates with bracket 4. During use, spring 6 can buffer external impact to a certain extent. For example, when a climber is climbing or is accidentally pulled, spring 6 can absorb some energy, reducing the risk of damage to the carabiner body 1 and connecting parts, protecting the climber's safety. A fixing post 7 is fixedly mounted inside the connecting post 3, and a fixing block 14 is fixedly mounted on the right side of the fixing post 7, with the fixing block 14 fitting snugly against the fixing plate 15.

[0023] The working principle and process of a carabiner self-closing locking device: In use, a carabiner self-closing locking device ensures the carabiner is in a closed and locked state. In this state, the connecting post 3, through the action of spring 6, is tightly fitted to the carabiner body 1, achieving initial closure. Simultaneously, the fixing block 14 and fixing plate 15 are tightly fitted, further enhancing the stability of the closure. Spring 13 is in its normal state, providing some support for the connecting rod 9; spring 16 is also in its normal state, maintaining the stable position of button 19. When it is necessary to open the carabiner, button 19 is pressed by hand. Since button 19 and carabiner body 1 are slidably connected, and spring 16 on the left side of button 19 is compressed when pressed, button 19 slides to the left along the internal slide rail of carabiner body 1, driving the connecting rod 9 to move. Button 19 is connected to connecting frame 10 via pivot 11. When button 19 slides to the left, it drives connecting frame 10 to move. Connecting frame 10 is fixed below connecting rod 9, thereby causing fixing rod 17 to rotate clockwise around pivot 18. During this process, damping rod 12 is stretched, spring 13 is also stretched, generating elastic potential energy, and spring 6 is compressed, generating elastic potential energy. At the same time, fixing block 14 separates from fixing plate 15, and the closed state of carabiner is released.
