Technical Field

[0001] The present application relates to the field of self-locking devices, and in particular to a self-locking device for profiles. Background Art

[0002] The self-locking device is an individual fall protection device used by workers at heights to climb up and down. The principles of the self-locking device for profiles and the self-locking device for wire ropes are similar. Both are devices used to prevent construction workers from falling. They can be used in high-altitude workplaces such as electricity, petroleum, communications, ships, construction, exterior wall spraying, and cleaning.

[0003] The self-locking device in the related art usually includes a mounting block and a supporting block, and a notch for the profile to enter is opened on the side of the mounting block and the supporting block close to each other, and at the same time, an anti-falling component capable of pressing against the profile is provided on the mounting block. When the self-locking device is used, the profile is placed between the mounting block and the supporting block, and the two sides of the profile are respectively placed in the corresponding notches, and then the mounting block and the supporting block are connected by multiple screws, thereby realizing the connection between the self-locking device and the profile.

[0004] With respect to the above-mentioned related technologies, when a user wants to install the self-locking device, the user needs to tighten several screws in sequence to realize the assembly of the self-locking device and the profile. However, tightening multiple screws in sequence is troublesome, so that the self-locking device has the defect of poor convenience of use, which needs to be improved. Summary of the invention

[0005] In order to improve the ease of use of the self-locking device, the present application provides a self-locking device for a profile.

[0006] The self-locking device for profiles provided in this application adopts the following technical solution:

[0007] A self-locking device for a profile comprises a mounting block, a receiving block and an anti-falling component, wherein the mounting block and the receiving block are respectively provided with a limiting groove for the profile to enter on one side where the mounting block and the receiving block are close to each other, a mounting hole is horizontally opened on the mounting block, a mounting rod is provided on the side wall of the receiving block, the mounting rod is slidably inserted in the mounting hole, and a locking mechanism capable of limiting the horizontal movement of the mounting rod is provided on the mounting block.

[0008] By adopting the above technical solution, when the self-locking device needs to be installed, the mounting block and the receiving block are brought close to each other, and the mounting rod is inserted into the mounting hole. Subsequently, by using the locking mechanism to limit the mounting rod in the horizontal direction, the position of the receiving block and the mounting block in the direction away from each other can be limited, thereby realizing the assembly of the self-locking device and the profile. This design eliminates the need for users to tighten multiple screws in sequence, thereby improving the convenience of using the self-locking device. At the same time, when the user disassembles the self-locking device, it only needs to open the locking mechanism to unlock the mounting block and the receiving block, thereby further improving the convenience of use.

[0009] Optionally, two mounting rods and two mounting holes are respectively provided, the two mounting rods are distributed at both ends of the receiving block and are respectively slidably inserted into the corresponding mounting holes, and two locking mechanisms are provided, which respectively lock the corresponding mounting rods.

[0010] By adopting the above technical solution, two mounting rods and two locking mechanisms are provided, and the locking mechanisms can control the corresponding mounting rods to be unlocked or locked. Only when the two locking mechanisms are opened at the same time, the mounting block and the receiving block can be unlocked, thereby reducing the risk of the user accidentally opening one locking mechanism and causing the mounting block and the receiving block to be unlocked, thereby improving the safety of the self-locking device.

[0011] Optionally, a support hole connected to the mounting hole is vertically opened on the mounting block, and each of the locking mechanisms includes a locking rod vertically slidably passed through the supporting hole and a locking ring arranged on the corresponding locking rod, and a locking groove for the corresponding locking ring to be inserted into the side wall of each mounting rod is opened, and a driving member is arranged in the supporting hole, and the driving member can make the two locking rods respectively snap into the corresponding locking grooves.

[0012] By adopting the above technical solution, when the two locking rings are respectively inserted into the corresponding locking grooves or respectively removed from the corresponding locking grooves, the mounting rod can be locked or unlocked. By providing a locking mechanism with a simple structure, convenient operation, and convenient unlocking and locking, the mounting block and the receiving block can be quickly unlocked and locked, thereby improving the work efficiency when assembling and disassembling the self-locking device.

[0013] Optionally, the driving member is a return spring arranged in the support hole, and both ends of the return spring are respectively connected to the corresponding locking rods. The return spring is used to drive the two locking rods away from each other, and a limiting mechanism capable of limiting the two locking rods from sliding out of the support hole is provided in the support hole.

[0014] By adopting the above technical solution, when the two locking rods approach each other and make the two locking rings respectively come out of the corresponding locking grooves, the return spring is gradually compressed. When the two locking rods are released, the two locking rods move away from each other under the elastic force of the return spring, and make the two locking rings respectively snap into the corresponding locking grooves. By setting a driving member with a simple structure and easy operation, the two locking rods and the locking rings can be quickly reset, thereby improving the work efficiency when locking or unlocking the mounting block and the receiving block. At the same time, the locking rod is blocked and limited by the limiting mechanism to prevent the locking rod from sliding out of the supporting hole, thereby improving the use stability of the self-locking device.

[0015] Optionally, the limiting mechanism includes limiting rings respectively arranged at one end of the two locking rods close to each other and two limiting blocks respectively arranged in the supporting holes, the two limiting rings are respectively located between the two limiting blocks, and the limiting blocks can block the corresponding limiting rings.

[0016] By adopting the above technical solution, when the two locking rods are away from each other and the two limiting rings are respectively in contact with the corresponding limiting blocks, the locking limit can be achieved. By setting a limiting mechanism with a simple structure and good limiting effect, the maximum sliding distance of the locking rod can be stably limited, further improving the use stability of the self-locking device.

[0017] Optionally, the anti-fall component includes a mounting frame arranged on the side wall of the mounting block, a mounting shaft horizontally arranged on the mounting frame, and a clamping block rotatably sleeved on the mounting shaft, and the clamping block can clamp the profile at one end close to the limiting groove.

[0018] By adopting the above technical solution, when the end of the pressing block away from the limiting groove flips downward, the end of the pressing block close to the limiting groove flips upward and presses against the profile, and then the friction between the pressing block and the profile can limit the self-locking device in the vertical direction. By setting an anti-falling component with a simple structure, convenient use, and stable limiting effect, the self-locking device can be stably limited in the vertical direction, thereby ensuring the anti-falling ability of the self-locking device.

[0019] Optionally, a support shaft is horizontally rotatably provided on the mounting frame, support blocks are respectively provided on the side walls of the two limiting rings, the two support blocks are respectively connected to the support shaft via flexible pull wires, and a control mechanism capable of driving the support shaft to rotate is provided between the mounting frame and the clamping block.

[0020] By adopting the above technical solution, the control mechanism drives the support shaft to rotate, and the two pull wires are respectively wrapped around the support shaft, and then the two pull wires can drive the corresponding support blocks to move, so that the two locking rods are close to each other. This design allows the user to unlock the two locking mechanisms at the same time only through the control mechanism, thereby improving the work efficiency when disassembling the self-locking device.

[0021] Optionally, the control mechanism includes a slider slidably set on the clamping block, a rack hinged on the slider, and a gear set on the support shaft, the slider is located on the side of the clamping block away from the limiting groove, the gear is meshed with the rack, and the mounting frame is provided with a guide rail for the rack to slide vertically.

[0022] By adopting the above technical solution, when the end of the abutting block away from the limiting groove flips upward, the slider can control the rack to move upward along the guide rail, and then the rack can drive the gear to drive the support shaft to rotate. By setting a control mechanism with a simple structure, convenient operation, and stable driving effect, the support shaft can be rotated quickly, thereby realizing the rapid unlocking of the two locking mechanisms, and further improving the work efficiency when disassembling the self-locking device. At the same time, this design is ingenious, and by flipping the abutting block upward, the two locking mechanisms can be unlocked at the same time, which can not only realize the rational use of the abutting block, but also improve the linkage between the components, thereby improving practicality.

[0023] Optionally, a limiting hole is vertically provided on the mounting frame, a limiting rod is threadedly passed through the limiting hole, the limiting rod can prevent the end of the clamping block away from the limiting groove from flipping upward, and a hand wheel is provided at the upper end of the limiting rod.

[0024] By adopting the above technical solution and providing a limit rod that can prevent the pressing block from flipping upward, the problem of the pressing block flipping upward during the use of the self-locking device and causing the self-locking device to be unlocked can be avoided, thereby improving the safety of the self-locking device.

[0025] Optionally, a return spring is provided between the pressing block and the mounting bracket, and the return spring can drive the end of the pressing block away from the limiting groove to flip upward.

[0026] By adopting the above technical solution, a reset spring is provided and the reset spring is used to drive the pressing block to flip, thereby achieving rapid and automatic reset of the pressing block, thereby improving the convenience of use.

[0028] By using the locking mechanism to limit the horizontal position of the mounting rod, the position of the receiving block and the mounting block in the direction away from each other can be limited, thereby realizing the assembly of the self-locking device and the profile. This design eliminates the need for users to tighten multiple screws in sequence, thereby improving the convenience of using the self-locking device.

[0029] By providing two locking mechanisms, the mounting block and the receiving block can be unlocked only when the two locking mechanisms are opened at the same time, thereby reducing the risk of the mounting block and the receiving block being unlocked due to the user accidentally opening one locking mechanism, thereby improving the safety of the self-locking device;

[0030] By utilizing the control mechanism to drive the two locking rods to move simultaneously, the two locking mechanisms are unlocked simultaneously, thereby improving the work efficiency when disassembling the self-locking device. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following is combined with Figure 1-8 This application is described in further detail.

[0041] The present application embodiment discloses a self-locking device for a profile. Figure 1 and Figure 2 The self-locking device for profiles comprises a mounting block 1 and a receiving block 2. The mounting block 1 and the receiving block 2 are provided with a limiting groove 3 for the profile to enter on one side thereof. At the same time, an anti-falling component 4 capable of pressing against the profile is provided on the mounting block 1 to realize the anti-falling protection of the user.

[0042] Reference Figure 2 and Figure 3 The inner walls on both sides of each limiting groove 3 are rotatably connected to a plurality of rollers 22, and the plurality of rollers 22 located in the same limiting groove 3 can abut against the corresponding surface of the profile to reduce the friction between the self-locking device and the profile, thereby improving the smoothness of the movement of the self-locking device.

[0043] Reference Figure 4 and Figure 5 , mounting holes 5 are horizontally opened at both ends of the side wall of the mounting block 1 near the receiving block 2, mounting rods 6 are horizontally fixedly connected at both ends of the side wall of the receiving block 2, and the two mounting rods 6 are horizontally slidably inserted into the corresponding mounting holes 5. At the same time, two locking mechanisms 8 are provided on the mounting block 1, which can respectively limit the horizontal movement of the corresponding mounting rods 6.

[0044] Reference Figure 4 and Figure 5 The mounting block 1 is vertically provided with a support hole 9 connected to the mounting hole 5. Each locking mechanism 8 includes a locking rod 81 vertically slidably inserted into the support hole 9, and the two locking rods 81 can move closer to or farther from each other. The middle of the two locking rods 81 is respectively fixed with a locking ring 82, and the circumferential side walls of the two mounting rods 6 are respectively provided with a locking groove 10 for the corresponding locking ring 82 to be inserted into.

[0045] When the two locking rods 81 move closer to or farther from each other and make the two locking rings 82 move closer to or farther from each other, the two locking rings 82 can be released from or inserted into the corresponding locking grooves 10, thereby achieving unlocking or locking of the two mounting rods 6.

[0046] Reference Figure 4 and Figure 5 A driving member capable of driving the two locking rods 81 away from each other and causing the two locking rings 82 to be respectively inserted into the corresponding locking grooves 10 is arranged in the support hole 9. The driving member is a return spring 11 arranged in the support hole 9. Both ends of the return spring 11 are respectively fixedly connected to the corresponding locking rods 81, and the return spring 11 can drive the two locking rods 81 away from each other. At the same time, a limiting mechanism 12 capable of limiting the two locking rods 81 from sliding out of the support hole 9 is arranged in the support hole 9, so as to limit the maximum sliding stroke of the locking rods 81.

[0047] When the two locking rods 81 are close to each other and the two locking rings 82 are respectively disengaged from the corresponding locking grooves 10, the two installation rods 6 can be unlocked, and at this time, the return spring 11 is in a compressed state. When the two locking rods 81 are released, the two locking rods 81 are separated from each other under the elastic force of the return spring 11, and the two locking rings 82 are respectively inserted into the corresponding locking grooves 10, thereby locking the two installation rods 6.

[0048] Reference Figure 4 and Figure 5 The limiting mechanism 12 includes limiting rings 121 respectively fixedly sleeved on the ends of the two locking rods 81 close to each other, and two limiting blocks 122 are fixedly connected to the inner wall of the support hole 9. The two limiting rings 121 are respectively located between the two limiting blocks 122, and the limiting blocks 122 can block the corresponding limiting rings 121. When the two locking rods 81 are away from each other and the limiting rings 121 are in contact with the corresponding limiting blocks 122, the locking rings 82 are just inserted into the corresponding locking grooves 10 to achieve rapid locking of the mounting rod 6.

[0049] Reference Figure 5 and Figure 6 The anti-falling assembly 4 includes a mounting frame 41 integrally formed on the side wall of the mounting block 1 close to the receiving block 2, and a mounting shaft 42 is horizontally fixedly connected to the mounting frame 41. The side wall of the receiving block 2 is provided with a clearance groove 7 for the mounting shaft 42 to be inserted, so as to improve compactness.

[0050] Reference Figure 5 and Figure 6A tightening block 43 is sleeved on the installation shaft 42, and the tightening block 43 and the installation shaft 42 are rotatably matched through a bearing. At the same time, the end of the tightening block 43 close to the limiting groove 3 can be pressed against the profile, and the side of the tightening block 43 away from the limiting groove 3 is penetrated by an assembly hole 13 for the protection rope to pass through.

[0051] When the user passes the waist protection rope through the assembly hole 13 and connects the protection rope with the abutting block 43, once the user falls, the end of the abutting block 43 away from the limiting groove 3 can be turned downward under the pull of the protection rope, and then the end of the abutting block 43 close to the limiting groove 3 rotates upward and abuts against the profile. At this time, the friction between the abutting block 43 and the profile can fix the self-locking device and the profile to achieve anti-fall protection for the user.

[0052] Reference Figure 5 and Figure 6 A return spring 14 is arranged between the clamping block 43 and the mounting frame 41, one end of the return spring 14 is fixedly connected to the clamping block 43, and the other end is fixedly connected to the mounting frame 41, and the return spring 14 can drive the end of the clamping block 43 away from the limiting groove 3 to flip upward to realize automatic resetting of the clamping block 43.

[0053] Reference Figure 7 and Figure 8 The mounting frame 41 is horizontally rotatably connected with a support shaft 15 located between two limit rings 121, and the side walls of the two limit rings 121 are respectively fixedly connected with support blocks 16. At the same time, a nylon pull wire 17 is arranged between the support block 16 and the support shaft 15, one end of the pull wire 17 is fixedly connected to the corresponding support block 16, and the other end is wound around the corresponding support shaft 15 and fixedly connected to the corresponding support shaft 15. At the same time, a control mechanism 18 capable of driving the support shaft 15 to rotate is arranged between the mounting frame 41 and the abutting block 43.

[0054] When the control mechanism 18 drives the support shaft 15 to rotate, the two pull wires 17 are gradually wound around the support shaft 15, and then the two support blocks 16 are pulled closer to each other by the corresponding pull wires 17. Subsequently, the support blocks 16 drive the corresponding limit rings 121 and the locking rods 81 and the locking rings 82 to move, so that the two locking rings 82 are respectively disengaged from the corresponding locking grooves 10, thereby realizing the synchronous unlocking of the two mounting rods 6.

[0055] Reference Figure 7 and Figure 8The control mechanism 18 includes a slider 181 disposed on the side of the abutting block 43 away from the limiting groove 3, and the slider 181 is slidably connected to the abutting block 43. A rack 182 is hinged on the upper end of the slider 181, and a gear 183 meshing with the rack 182 is fixedly sleeved on the support shaft 15. At the same time, a guide rail 23 for the rack 182 to slide vertically is fixedly connected to the side wall of the mounting frame 41 to limit the rack 182.

[0056] When the end of the abutting block 43 away from the limiting groove 3 turns upward, the slider 181 can control the rack 182 to move upward along the guide rail 23. Subsequently, the rack 182 can drive the gear 183 to drive the support shaft 15 to rotate, and then the two pull wires 17 can pull the corresponding locking rod 81 to move.

[0057] Reference Figure 1 and Figure 3 The mounting frame 41 is vertically provided with a limiting hole 19, and a limiting rod 20 is threadedly provided in the limiting hole 19. The limiting rod 20 can block the side of the abutting block 43 away from the limiting groove 3, thereby preventing the end of the abutting block 43 away from the limiting groove 3 from turning upward and causing the two locking rods 81 to be unlocked. At the same time, a hand wheel 21 is fixedly connected to the upper end of the limiting rod 20, so that the user can quickly rotate the limiting rod 20.

[0058] The implementation principle of a self-locking device for a profile in the embodiment of the present application is as follows: when the self-locking device needs to be assembled, the two locking rods 81 are pressed respectively to drive the corresponding locking rings 82 to move, so that the two locking rods 81 are close to each other, and the two locking rings 82 are respectively disengaged from the corresponding locking grooves 10. Subsequently, the mounting block 1 and the receiving block 2 are pulled away from each other, and the profile is placed between the mounting block 1 and the receiving block 2, and then the mounting block 1 and the receiving block 2 are pushed close to each other, and the profile enters between the two limiting grooves 3. Then, the two locking rods 81 are released, and the two locking rods 81 are driven away from each other by the return spring 11, so that the two locking rings 82 are moved away from each other and are respectively inserted into the corresponding locking grooves 10, thereby realizing the locking of the mounting block 1 and the receiving block 2, and then realizing the assembly of the self-locking device.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
