Description
Technical Field
[0001] This utility model relates to the field of lock cylinder pull rod technology, and in particular to a high-strength lock cylinder pull rod for automobile doors. Background Technology
[0002] The lock cylinder lever is a key transmission component in the car door lock mechanism. Its main function is to transmit the physical pulling force of the outer or inner handle to the lock body, thereby triggering the bolt to retract and opening the car door. The two ends of this component are connected to the handle base and the lock cylinder lever arm respectively through a snap-fit or threaded structure. If the lever is deformed, it may cause increased door opening resistance, abnormal noise, or even failure of the inner or outer handle.
[0003] Existing lock cylinder levers are mostly one-piece molded, but there are many models, their application scenarios are specific and limited, and they lack adjustable structures. When there is no original lock cylinder lever available, the substitute lever is sometimes not long enough. Therefore, this application provides a high-strength lock cylinder lever for automotive doors to meet the needs. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a high-strength lock cylinder pull rod for automobile doors to solve the problems that existing lock cylinder pull rods are basically integrally formed, but there are many models, the application scenarios are specific and limited, there is a lack of adjustable structure, and the pull rods used as substitutes are sometimes not long enough when there is no original lock cylinder pull rod available.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A high-strength lock cylinder pull rod for automobile doors includes a pull rod one and a pull rod two, which are mounted together by a connecting mechanism. The connecting mechanism includes a fixing ring, a threaded cylinder with threads on its outer wall fixedly connected to the bottom of the fixing ring, and two opposing clamping blocks slidably connected to the top of the fixing ring. Each clamping block has an inclined surface on its opposite side. Two sliding pins are also slidably connected to the fixing ring, which are opposite to each other and can abut against the inclined surfaces. Protective pads are provided between the clamping blocks.
[0006] Preferably, the sliding column is fixedly connected to both the top and bottom sides of the fixed ring with locking blocks to prevent the sliding column from detaching from the fixed ring.
[0007] Preferably, a fixing frame is fixedly connected to one end of the second pull rod near the first pull rod, and the fixing frame is helically connected to the threaded cylinder.
[0008] Preferably, the threaded cylinder is threadedly connected to a rotating ring, and the outer wall of the rotating ring is provided with a plurality of fixing blocks in a circumferential shape, and each fixing block is provided with a through groove.
[0009] Preferably, the through groove is internally slidably connected with a C-shaped rod for linkage with the second tie rod.
[0010] Preferably, a protective shell is fixedly connected to the outer wall of the fixed frame, and the outer wall of the protective shell has a plurality of slots arranged in a circumferential shape.
[0011] Compared with the prior art, this utility model has at least the following beneficial effects: In the above solution, by setting a connecting mechanism, during use, the second pull rod can be first connected to the threaded cylinder through the fixed frame, and then one end of the first pull rod can be inserted into the inside of the fixed ring. Then, the rotating ring is rotated. As the rotating ring is connected to the threaded cylinder, it will move towards the fixed ring on the threaded cylinder. When the rotating ring moves to the point of contacting the sliding column, it will drive the sliding column to move with the rotating ring. The sliding column will gradually contact the inclined surface on the fixed ring and the clamping block. After the sliding column contacts the inclined surface, it will drive the clamping block to gradually move towards the middle of the fixed ring. When the rotating ring moves to the bottom of the fixed ring, it will cause the clamping block to clamp the first pull rod. With the help of the protective pad, the clamping and fixing effect is further improved. The advantage of this is that different lock cylinder pull rods can be combined together, which makes it easy to use in cases where there are different models of existing lock cylinder pull rods, thereby expanding the application scenarios.
[0012] By setting a C-shaped rod, after the clamping block clamps the first pull rod, the C-shaped rod, which slides inside the through groove on the fixed block, can be slid outward. As it slides, the C-shaped rod enters the slot on the protective shell, completing the connection. When the second pull rod rotates, it drives the C-shaped rod through the slot on the protective shell, causing the rotating ring to rotate as well. This rotating ring then drives the threaded cylinder and the fixed ring, ultimately causing the first pull rod, clamped by the clamping block, to rotate as well. If the lengths of the first and second pull rods are still slightly different after assembly, the C-shaped rod can be slid out of the slot, and then the protective shell can be rotated in the opposite direction on the threaded cylinder, driving the fixed frame and... Pull rod two moves away from the swivel, thus stretching it outwards. When pull rod two moves to the appropriate distance, slide the C-shaped rod again to let it enter the slot, so that the swivel is reconnected to the protective shell through the C-shaped rod. When it needs to be removed, simply rotate the protective shell in the opposite direction to move the swivel away from the fixed ring on the threaded cylinder through the C-shaped rod. This will allow the sliding pin to no longer restrict the clamping block, thus freeing pull rod one from being clamped and fixed, making it easy to pull pull rod one out directly. The advantage of this is that it is easy to adjust the appropriate length according to the usage scenario when the original lock cylinder pull rod is not available, increasing adaptability.

Detailed Implementation
[0017] The high-strength lock cylinder rod for automobile doors provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.
[0018] like Figure 1 and Figure 2As shown, an embodiment of this utility model provides a high-strength lock cylinder pull rod for automobile doors, including a pull rod 1 and a pull rod 2. The pull rod 1 and the pull rod 2 are installed together by a connecting mechanism 3. The connecting mechanism 3 includes a fixing ring 31. A threaded cylinder 32 with threads on its outer wall is fixedly connected to the bottom of the fixing ring 31. Two opposing clamping blocks 33 are slidably connected to the top of the fixing ring 31. Each clamping block 33 has an inclined surface 34 on its opposite side. Two sliding pins 36 are also slidably connected to the fixing ring 31. The sliding pins 36 are opposite and can abut against the inclined surface 34 respectively. A clamping mechanism is provided between the clamping blocks 33. The protective pad 35 and the sliding column 36 are fixedly connected to the top and bottom sides of the fixed ring 31 with locking blocks 37 to prevent the sliding column 36 from detaching from the fixed ring 31. The end of the pull rod 2 near the pull rod 1 is fixedly connected to the fixed frame 10. The fixed frame 10 is screwed to the threaded cylinder 32. The threaded cylinder 32 is threadedly connected to the rotating ring 6. Multiple fixing blocks 7 are arranged in a circumferential shape on the outer wall of the rotating ring 6. Each fixing block 7 is provided with a through groove 8. A C-shaped rod 9 for linkage with the pull rod 2 is slidably connected inside the through groove 8. The outer wall of the fixed frame 10 is fixedly connected to the protective shell 4. Several slots 5 are opened in a circumferential shape on the outer wall of the protective shell 4.
[0019] By setting the connecting mechanism 3, in use, the pull rod 2 can be first connected to the threaded cylinder 32 by the fixed frame 10, and then one end of the pull rod 1 can be inserted into the inside of the fixed ring 31. Then, the rotating ring 6 is rotated. When the rotating ring 6 is rotated, it will move towards the fixed ring 31 on the threaded cylinder 32 because it is connected to the threaded cylinder 32 by the threaded cylinder 32. When the rotating ring 6 moves to the point of contacting the sliding column 36, it will drive the sliding column 36 to move together with the rotating ring 6. The sliding column 36 will gradually contact the inclined surface 34 on the clamping block 33 on the fixed ring 31. After the sliding column 36 contacts the inclined surface 34, it will drive the clamping block 33 to gradually move towards the middle of the fixed ring 31. When the rotating ring 6 moves to the bottom of the fixed ring 31, it will cause the clamping block 33 to clamp the pull rod 1. With the help of the protective pad 35, the clamping and fixing effect is further improved. The advantage of doing this is that different lock cylinder pull rods can be combined together, which makes it easy to use in the case of different lock cylinder pull rod models, thereby expanding the application scenarios.
[0020] By setting the C-shaped rod 9, after the clamping block 33 clamps the pull rod 1, the C-shaped rod 9, which slides inside the through groove 8 on the fixing block 7, can be slid outward. As it slides, the C-shaped rod 9 will enter the slot 5 on the protective shell 4, completing the connection with the protective shell 4. When the pull rod 2 rotates, it will drive the C-shaped rod 9 through the slot 5 on the protective shell 4, causing the rotating ring 6 to rotate as well. This, in turn, drives the threaded cylinder 32 and the fixing ring 31, ultimately causing the pull rod 1, clamped by the clamping block 33, to rotate together. If the length of the pull rod 1 and pull rod 2 is still slightly different after assembly, the C-shaped rod 9 can be slid out of the slot 5, and then the protective shell 4 can be rotated in the opposite direction on the threaded cylinder 32 to drive the fixing ring 31. The fixed frame 10 and the pull rod 2 move away from the rotating ring 6, thereby stretching the pull rod 2 outward. When the pull rod 2 moves to the appropriate distance, the C-shaped rod 9 is slid back into the slot 5, so that the rotating ring 6 is reconnected to the protective shell 4 through the C-shaped rod 9. When it is necessary to remove it, simply rotate the protective shell 4 in the opposite direction to drive the rotating ring 6 to move away from the fixed ring 31 on the threaded cylinder 32, so that the sliding column 36 no longer restricts the clamping block 33, thus the pull rod 1 is no longer clamped and fixed, making it easy to pull out the pull rod 1 directly. The advantage of doing this is that it is easy to adjust the appropriate length according to the needs of the usage scenario when the original lock cylinder pull rod is not available, which increases the adaptability.
[0021] The technical solution provided by this utility model, by setting a connecting mechanism 3, allows the pull rod 2 to be first spirally connected to the threaded cylinder 32 via the fixed frame 10. Then, one end of the pull rod 1 is inserted into the inside of the fixed ring 31, and the rotating ring 6 is rotated. As the rotating ring 6 is spirally connected to the threaded cylinder 32, it moves towards the fixed ring 31 along with the rotation. When the rotating ring 6 moves to contact the sliding column 36, it will drive the sliding column 36 to move together with the rotating ring 6. The sliding column 36 will gradually contact the inclined surface 34 on the clamping block 33 on the fixed ring 31. After the sliding column 36 contacts the inclined surface 34, it will drive the clamping block 33 to gradually move towards the middle of the fixed ring 31. When the rotating ring 6 moves to the bottom of the fixed ring 31, the clamping block 33 will clamp the pull rod 1. With the help of the protective pad 35, the clamping and fixing effect is further improved. The advantage of this is that different lock cylinder pull rods can be combined together, making it easy to use in cases where there are different models of existing lock cylinder pull rods, thereby expanding the application scenarios.
[0022] By setting the C-shaped rod 9, after the clamping block 33 clamps the pull rod 1, the C-shaped rod 9, which slides inside the through groove 8 on the fixing block 7, can be slid outward. As it slides, the C-shaped rod 9 will enter the slot 5 on the protective shell 4, completing the connection with the protective shell 4. When the pull rod 2 rotates, it will drive the C-shaped rod 9 through the slot 5 on the protective shell 4, causing the rotating ring 6 to rotate as well. This, in turn, drives the threaded cylinder 32 and the fixing ring 31, ultimately causing the pull rod 1, clamped by the clamping block 33, to rotate together. If the length of the pull rod 1 and pull rod 2 is still slightly different after assembly, the C-shaped rod 9 can be slid out of the slot 5, and then the protective shell 4 can be rotated in the opposite direction on the threaded cylinder 32 to drive the fixing ring 31. The fixed frame 10 and the pull rod 2 move away from the rotating ring 6, thereby stretching the pull rod 2 outward. When the pull rod 2 moves to the appropriate distance, the C-shaped rod 9 is slid back into the slot 5, so that the rotating ring 6 is reconnected to the protective shell 4 through the C-shaped rod 9. When it is necessary to remove it, simply rotate the protective shell 4 in the opposite direction to drive the rotating ring 6 to move away from the fixed ring 31 on the threaded cylinder 32, so that the sliding column 36 no longer restricts the clamping block 33, thus the pull rod 1 is no longer clamped and fixed, making it easy to pull out the pull rod 1 directly. The advantage of doing this is that it is easy to adjust the appropriate length according to the needs of the usage scenario when the original lock cylinder pull rod is not available, which increases the adaptability.
