Description

Technical Field

[0001] This utility model relates to the field of interior assembly technology for transportation, specifically a side-top pull rope lock structure that can achieve center opening and closing. Background Technology

[0002] In the side and top assembly of rail transit vehicles, locks are key components that ensure stable installation and convenient maintenance. Currently widely used traditional rotary locks have significant drawbacks.

[0003] Because the side roofs of trains are large, typically longer than 2 meters, and heavy, a rotary lock needs to be installed at each end to ensure stability. This design makes operation extremely inconvenient: opening and closing the side roof requires operating the locks at both ends separately. One person cannot manage both simultaneously; two people must work together. One person holds the side roof to prevent it from falling, while the other locks the rotary locks one by one. Not only does each operation take more than five minutes, but there is also a safety hazard of the side roof accidentally slipping. Furthermore, operating the locks at both ends independently can easily result in inconsistent tightening, leading to uneven stress on the side roof. After long-term vibration, this may cause abnormal noises or structural deformation.

[0004] Therefore, a pull-rope lock structure that can control the synchronous opening and closing of both ends through a single lock in the middle is needed to solve the problems of cumbersome operation, reliance on multiple people, and insufficient security in the existing technology. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a side-top pull rope lock structure that can achieve center opening and closing, possessing the advantage of rapid opening and closing of the entire product, and solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a side-top pull rope lock structure capable of opening and closing in the middle, comprising a housing, a central lock body provided on the side of the housing, the central lock body comprising a lock shell and a lock cylinder, linkage arms symmetrically welded on the side of the lock cylinder, two sets of fixing grooves fixed on the side of the housing, a lock rope installed on the inner wall of the fixing groove, one end of the lock rope connected to the corresponding linkage arm, fixing seats fixed at both ends of the housing, hook locks installed on the side of the fixing seats, the other end of the lock rope connected to the corresponding hook lock, and an adjustment component corresponding to the lock rope provided on the side of the housing.

[0007] Furthermore, the locking rope is made of brake wire material, with an outer PVC sheath and an inner multi-strand steel wire. When the locking rope is fixed to the fixing groove, the outer PVC sheath is fixed to the fixing groove, and the inner multi-strand steel wire is connected to the linkage arm.

[0008] The above method uses the rotation of the linkage arm to move the steel wire inside the lock rope.

[0009] Furthermore, the hook lock includes a connecting seat, on the side of which a locking shaft and a hook lock are mounted, and the other end of the locking rope is connected to the hook lock.

[0010] The above method allows the hook lock to be opened and closed via the locking rope.

[0011] Furthermore, a spring mechanism is provided between the lock rope and the hook lock. One end of the spring mechanism is connected to the rigid outer layer of the lock rope end, and the other end of the spring mechanism is connected to the steel wire of the inner layer of the lock rope.

[0012] The above solution utilizes the spring force of the spring mechanism to help the hook lock reset, which facilitates the closing of the side-top product.

[0013] Furthermore, the adjustment assembly includes a support base, which is fixed to the housing. Two mounting seats are fixed to the inner wall of the support base. A support wheel and a fixing plate are mounted on the side of the mounting seats. The locking rope passes through the fixing plate. The outer PVE sleeve of the locking rope is fixed to the fixing plate. The outer PVE sleeve of the locking rope between the two fixing plates is removed.

[0014] The above method exposes the internal multiple strands of steel wire in the lock rope between the two fixing plates without affecting the normal use of the lock rope.

[0015] Furthermore, a hydraulic rod is installed on the side of the bearing seat, and a rotating wheel is installed at the output end of the hydraulic rod. The rotating wheel is in contact with the internal steel wire of the locking rope.

[0016] The above method uses a hydraulic rod to drive a rotating wheel to rise and fall, thereby squeezing the steel wires inside the lock rope and adjusting the rope's tension.

[0017] Compared with the prior art, the technical solution of this utility model has the following beneficial effects: This side-top pull rope lock structure enables opening and closing from the center. By setting a central lock body, rotating the lock cylinder links the lock rope, which drives the hook locks at both ends to open, completing the opening of the entire side-top product. The tail has a spring mechanism to help the hook locks return to their original position, facilitating the closing of the side-top product. This allows for quick and safe opening and closing of the entire product. An adjustment component can be set to adjust the tension of the lock rope, preventing the lock rope from compressing the spring while also preventing the lock rope from becoming too loose and affecting the overall function, thus achieving the purpose of quick opening and closing of the entire product.

Detailed Implementation

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of a side-top pull rope lock structure that can achieve center opening and closing includes a housing 1. A central lock body 2 is provided on the side of the housing 1. The central lock body 2 includes a lock shell 201 and a lock cylinder 202. A linkage arm 203 is symmetrically welded on the side of the lock cylinder 202. Two sets of fixing grooves 3 are fixed on the side of the housing 1. A lock rope 4 is installed on the inner wall of the fixing groove 3. One end of the lock rope 4 is connected to the corresponding linkage arm 203. Fixing seats 5 are fixed at both ends of the housing 1. Hook locks 6 are installed on the side of the fixing seats 5. The other end of the lock rope 4 is connected to the corresponding hook lock 6. An adjustment component 7 corresponding to the lock rope 4 is provided on the side of the housing 1.

[0022] Please see Figure 2 , Figure 4 and Figure 5The locking rope 4 is made of brake wire material, with an outer PVC sheath and an inner multi-strand steel wire. When the locking rope 4 is fixed to the fixing groove 3, the outer PVC sheath is fixed to the fixing groove 3, and the inner multi-strand steel wire is connected to the linkage arm 203. The rotation of the linkage arm 203 pulls the movement of the steel wire inside the locking rope 4. The hook lock 6 includes a connecting seat 601. The side of the connecting seat 601 is equipped with a locking shaft 602 and a hook lock 6. The other end of the locking rope 4 is connected to the hook lock 6. The locking rope 4 can drive the hook lock 6 to open and close.

[0023] Please see Figure 3 , Figure 4 and Figure 5 A spring mechanism 8 is provided between the locking rope 4 and the hook lock 6. One end of the spring mechanism 8 is connected to the rigid outer layer of the end of the locking rope 4, and the other end of the spring mechanism 8 is connected to the steel wire of the inner layer of the locking rope 4. The elastic force of the spring mechanism 8 helps the hook lock 6 to complete the reset, which is conducive to the closing of the side top product. The adjustment component 7 includes a support seat 701, which is fixed to the housing 1. Two mounting seats 702 are fixed on the inner wall of the support seat 701. The side of the mounting seat 702 is equipped with a support wheel 703 and a fixing plate 704. The locking rope 4 passes through the fixing plate 704. The outer PVE sleeve of the locking rope 4 is fixed to the fixing plate 704. The outer PVE sleeve of the locking rope 4 between the two fixing plates 704 is removed, and the internal multiple steel wires of the locking rope 4 are exposed between the two fixing plates 704 without affecting the normal use of the locking rope 4.

[0024] Please see Figure 1 , Figure 4 and Figure 5 A hydraulic rod 705 is installed on the side of the bearing seat 701. A rotating wheel 706 is installed at the output end of the hydraulic rod 705. The rotating wheel 706 is in contact with the internal steel wire of the locking rope 4. The hydraulic rod 705 can drive the rotating wheel 706 to rise and fall to squeeze the internal steel wire of the locking rope 4, thereby adjusting the tension of the rope.

[0025] It should be noted that during use, when adjusting the locking rope 4 using the adjusting component 7, attention must be paid to the tension of the spring mechanism 8. The appropriate length of the locking rope 4 is crucial for the operation of the entire locking mechanism. A taut locking rope 4 will compress the spring, causing the hook lock 6 to fail to close; a slack locking rope 4 will affect the overall function and generally requires manually resetting by turning the lock cylinder 202 again.

[0026] The working principle of the above embodiment is as follows: During use, by rotating the central lock body 2 with the key, the rotation of the lock cylinder 202 drives the linkage arm 203 to rotate. The rotation of the linkage arm 203 causes the lock rope 4 to rotate. The lock rope 4 is made of brake wire, which is soft. The lock rope 4 drives the hook locks 6 at both ends to open, thus completing the opening of the entire side top product. When resetting, the spring mechanism 8 drives the hook lock 6 to reset, which is conducive to closing the side top product. This helps to quickly complete the opening and closing of the entire product, which is safe and efficient. At the same time, it has a self-rebound function and does not require manual reset.

[0027] When it is necessary to adjust the tension of the locking rope 4, the hydraulic rod 705 drives the rotating wheel 706 to rise and fall. The rising and falling of the rotating wheel 706 compresses the steel wire inside the locking rope 4, thereby adjusting the tension of the rope. This avoids the locking rope 4 being too taut and compressing the spring, while also preventing the locking rope 4 from being too loose and affecting the overall function, thus achieving the purpose of quick opening and closing of the entire product.
