Description

Technical Field

[0001] This utility model relates to the field of brake wire core replacement technology, specifically a brake wire core replacement locking device. Background Technology

[0002] Brake cables are the core transmission components of the braking system, consisting of an internal metal wire core and an external protective sheath. After prolonged use, the wire core may fail due to wear, corrosion, or breakage, requiring replacement.

[0003] During the replacement of brake cables, it's important to understand that brake cables are consumable items and prone to damage over time. Because the original design of brake cables features fixed and non-replaceable cores and length adjustment rods, the cores themselves are not replaceable. Traditionally, this means replacing the entire cable after damage. This requires disassembling the entire brake cable and all plastic coverings before replacement, followed by reinstallation. This process is time-consuming, and the plastic coverings may not be installed tightly during reassembly, reducing efficiency and repair quality during brake cable core replacement. Utility Model Content

[0004] The purpose of this invention is to provide a brake wire core replacement and locking device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a brake cable core replacement and locking device, including a cable tube, with disassembly mechanisms at both ends of the cable tube.

[0006] The easy-to-disassemble mechanism includes a lock cap located on one side of the conduit. The lock cap has a wire inlet hole at the center of its top. The inner wall of the conduit has a rotating shaft. The top of the outer wall of the rotating shaft has a first threaded groove. The lock cap is threadedly connected to the top of the outer wall of the rotating shaft through the first threaded groove.

[0007] In one example, a groove is provided on the top of the outer wall of the shaft, and the groove is directly opposite the position of the lock cap.

[0008] In one example, a pressure table is fixedly connected to the middle of the outer wall of the shaft.

[0009] In one example, a top platform is fixedly connected to the top of the inner wall of the lock cap, and the top platform is directly opposite the pressure platform.

[0010] In one example, a cone is fixedly connected to the top of the shaft.

[0011] In one example, the bottom of the outer wall of the shaft is provided with a second threaded groove, and the shaft is threadedly connected to the conduit through the second threaded groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When replacing the internal brake cable core, the old core is pulled out from inside the cable housing, and then the new core is inserted into the inner wall of the cable housing through the handlebar end. The aforementioned easy-to-disassemble mechanism 2 is located... Figure 1 As shown, inside the spring coil, the wire core first passes through the inlet hole at the top of the lock cap and then through the internal thread of the lock cap, which connects the lock cap to the first threaded groove on the outer wall of the shaft. The wire core then exits from the groove on the outer wall of the shaft. A pressure plate is located on the outside of the shaft. The pressure plate works with the top lock cap to fix the wire core that has passed through the groove, preventing it from falling off during use. By changing the original non-replaceable brake cable design to a replaceable brake cable core, the car body does not need to be removed during the replacement process. This prevents the reinstalled car body from being less precise and causing abnormal noises or loosening later. Furthermore, this device is simpler and more convenient than the previous method of replacing the wire core, and it reduces the replacement cost by 60% compared to replacing the entire set.

[0014] 2. The top platform inside the lock cap is directly opposite the bottom pressure platform. The cooperation of the top platform and the pressure platform makes the wire core inside the wire groove more stable. The cone head is used to fix the wire core to the shaft for the first time, followed by a second fixation by the top platform and the pressure platform. This double fixation can extend its service life after fixation. The two locking and screw glue fixation inside the wire tube will not loosen. The protruding wire core is bound within the original spring ring, which is convenient for future readjustment. The second threaded groove is used to fix the shaft to the wire tube.

[0021] 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.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a brake wire core replacement and locking device, including a wire tube 1, with disassembly mechanisms 2 at both ends of the wire tube 1;

[0023] The easy-to-disassemble mechanism 2 includes a locking cap 201 located on one side of the conduit 1. The locking cap 201 has a wire inlet hole 202 at the center of its top. The inner wall of the conduit 1 is provided with a rotating shaft 203. The top of the outer wall of the rotating shaft 203 is provided with a first threaded groove 204. The locking cap 201 is threadedly connected to the top of the outer wall of the rotating shaft 203 through the first threaded groove 204.

[0024] A wire groove 205 is provided on the top of the outer wall of the rotating shaft 203, and the wire groove 205 is directly opposite the position of the lock cap 201.

[0025] A pressure table 206 is fixedly connected to the middle of the outer wall of the rotating shaft 203;

[0026] When replacing the brake cable core inside the tube, the old core is pulled out from inside the tube 1, and the new core is inserted into the inner wall of the tube 1 through the handlebar end. The aforementioned easy-to-disassemble mechanism 2 is located in... Figure 1As shown, inside the spring coil, the wire core first passes through the inlet hole 202 at the top of the lock cap 201 and then through the inside of the lock cap 201. The lock cap 201 has an internal thread, which connects the lock cap 201 to the first threaded groove 204 on the outer wall of the rotating shaft 203. The wire core then passes through the groove 205 on the outer wall of the rotating shaft 203. A pressure plate 206 is provided on the outside of the rotating shaft 203. The function of the pressure plate 206 is to cooperate with the top lock cap 201 to fix the wire core passing through the groove 205, preventing the wire core from falling off during use. By changing the original design of the brake cable's non-replaceable wire core to a replaceable brake cable core, it is not necessary to remove the car body during the replacement of the wire core. This prevents the reinstalled car body from being less precise and prevents abnormal noises and loosening later. Moreover, this device is simpler and more convenient than the previous method of replacing the wire core during the replacement of the lock cylinder, and reduces the replacement cost by 70% compared to replacing the entire set.

[0027] Furthermore, a top platform 207 is fixedly connected to the top of the inner wall of the lock cap 201, and the top platform 207 is directly opposite the pressure platform 206.

[0028] A cone head 3 is fixedly connected to the top of the rotating shaft 203.

[0029] The bottom of the outer wall of the rotating shaft 203 is provided with a second threaded groove 4, and the rotating shaft 203 is threadedly connected to the conduit 1 through the second threaded groove 4.

[0030] In use, the top platform 207 set inside the lock cap 201 is directly opposite the bottom pressure platform 206. With the cooperation of the top platform 207 and the pressure platform 206, the wire core located inside the wire groove 205 can be more stable. The cone head 3 is used to fix the wire core to the rotating shaft 203 for the first time, and then the top platform 207 and the pressure platform 206 fix it for the second time. With double fixation, its service life can be extended after fixation. The two locking and screw glue fixation inside the wire tube 1 will not loosen. The protruding wire core is bound in the original spring ring, which is convenient for future readjustment. The second threaded groove 4 is used to fix the rotating shaft 203 to the wire tube 1.
