Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a cable with adjustable stroke. Background Art

[0002] A cable usually consists of a cable rope and a cable sleeve. When in use, a steel wire rope is installed in the cable sleeve, and the cable rope can be pulled by an external force so that the cable rope can move in the cable sleeve. Among them, both ends of the cable sleeve are respectively fixed on corresponding fitting parts, and both ends of the cable rope are respectively fixedly connected to a driving part and a driven part. When the driving part at one end of the cable rope moves, the driven part at the other end can be driven by the cable rope, so as to transfer force and displacement from the driving part to the driven part. The lengths of the cable rope and the cable sleeve are fixed, so the maximum stroke of the cable cannot be changed. Among them, the maximum stroke of the cable will affect the transfer of displacement. In the actual production process, due to reasons such as process, the sizes of parts will fluctuate within the tolerance range, which will affect the transfer of displacement by the cable rope, and thus problems such as empty stroke or insufficient stroke may occur.

[0003] The Chinese utility model patent with the publication number of "CN209925415U" discloses a cable stroke adjuster, which includes a housing for movably connecting a steel wire rope of a cable and an adjusting core rod. An installation hole is provided on the housing, and the adjusting core rod is installed in the installation hole. A spring is arranged in the installation hole and the adjusting core rod can move along the depth direction of the installation hole. A locking part for fixing the adjusting core rod is also provided on the housing. The steel wire rope movably penetrates through the housing and the adjusting core rod in the depth direction parallel to the installation hole, and the adjusting core rod is slidably connected or threadedly connected to the installation hole.

[0004] Although the above-mentioned cable stroke adjuster solves the technical problem that the cable stroke cannot be adjusted, it still has the following defects:

[0005] Combined with the content of paragraphs 0084 to 0086 of the specification of this disclosure document, it can be known that a spring is arranged in the installation hole. Since the compression force of the spring changes dynamically with the compression degree, it is challenging to accurately adjust the cable stroke. And the spring itself has a maximum compression limit. The spring is placed in the installation hole, reducing the adjustable distance of the adjustment mechanism. In addition, according to the content of paragraphs 0091 to 0096 of this disclosure document, the adjustment mechanism adjusts the cable stroke by threadedly connecting the locking part to the adjusting core rod. If the locking part becomes loose, the adjusting core rod may be disengaged from the housing due to the elastic force of the spring in the installation hole, which will reduce the structural stability of the cable, and its structure is relatively complex and the assembly is cumbersome. Content of the Utility Model

[0006] The technical problem to be solved by the utility model is to provide a cable with adjustable stroke, which has high adjustment accuracy, simple structure and strong practicability, aiming at the deficiencies of the above-mentioned prior art.

[0007] To achieve the above object, the technical solution adopted by the present utility model is as follows: An adjustable-stroke cable, comprising a cable and a cable sleeve. The cable is sleeved in the cable sleeve. The cable sleeve includes a first cable sleeve and a second cable sleeve. An adjusting mechanism is provided between the first cable sleeve and the second cable sleeve. The adjusting mechanism includes an adjusting screw rod and an adjusting sleeve. The adjusting screw rod is provided with an external thread, and the adjusting sleeve is provided with an internal thread corresponding to the external thread. The adjusting sleeve is threadedly connected to the adjusting screw rod. One end of the first cable sleeve is connected to the end of the adjusting screw rod away from the adjusting sleeve, and one end of the second cable sleeve is connected to the end of the adjusting sleeve away from the adjusting screw rod.

[0008] By adopting the above technical solution: Through the adjusting screw rod and the adjusting sleeve, when it is necessary to adjust the stroke of the cable, rotating the adjusting sleeve one circle can make the adjusting sleeve extend or shorten by the length of one pitch relative to the adjusting screw rod, thereby realizing the displacement of the cable sleeve on the cable, and accurately adjusting the length of the exposed part of the cable. Compared with the prior art method of using a housing and an adjusting core rod and arranging a spring in the housing, the adjusting mechanism provided by the present utility model has higher adjustment accuracy, a simple overall structure, quick assembly, strong practicability, and a small volume of the adjusting mechanism, and can be applied to a variety of application scenarios.

[0009] The above-mentioned adjustable-stroke cable can be further provided as follows: A locking member is provided on the adjusting screw rod, and the locking member can lock and limit the adjusting sleeve on the adjusting screw rod.

[0010] By adopting the above technical solution: The locking member can effectively prevent the adjusting sleeve from shifting on the adjusting screw rod. When it is necessary to adjust the stroke, loosen the locking member and rotate the adjusting sleeve to move along the axis direction of the adjusting screw rod; when the adjustment of the stroke is completed, tighten the locking member, and the adjusting sleeve is limited by the locking member and remains in a fixed position.

[0011] The above-mentioned adjustable-stroke cable can be further provided as follows: The locking member includes a locking nut. The locking nut is a hexagonal nut, and the locking nut is threadedly connected to the adjusting screw rod.

[0012] By adopting the above technical solution: Using the locking nut as the locking member makes it simpler to lock or loosen the adjusting sleeve. When it is necessary to lock the adjusting sleeve, just tighten the locking nut; when it is necessary to rotate the adjusting sleeve, rotate and loosen the locking nut, and the locking nut moves away from the adjusting sleeve. At this time, rotating the adjusting sleeve can achieve the adjustment. And the locking nut is a hexagonal nut, which is more convenient to rotate the locking nut.

[0013] The above-mentioned adjustable-stroke cable can be further provided as follows: A first through hole is provided at the end of the adjusting screw rod away from the adjusting sleeve. There is a diameter gradient between one end and the middle of the first through hole. The diameter of the end is larger, and the first cable sleeve is nested in the first through hole.

[0014] By adopting the above technical solution: through the first through hole, the first cable sleeve can be sleeved in the first through hole. The first cable sleeve can be linked with the adjusting screw rod. Moreover, there is a diameter gradient between the end and the middle of the first through hole, and the diameter of the end is slightly larger than that of the middle. The first locking sleeve can smoothly slide into the first through hole along the diameter gradient.

[0015] The above cable with adjustable stroke can be further configured as follows: at one end of the adjusting sleeve away from the adjusting screw rod, there is a second through hole. There is a diameter gradient between one end and the middle of the second through hole, and the diameter of the end is larger. The second through hole is nested and matched with the second cable sleeve.

[0016] By adopting the above technical solution: through the second through hole, the second cable sleeve can be sleeved in the second through hole. The second cable sleeve is linked with the adjusting sleeve. Moreover, there is a diameter gradient between the end and the middle of the second through hole, and the diameter of the end is slightly larger than that of the middle. The second locking sleeve can smoothly slide into the second through hole along the diameter gradient.

[0017] The above cable with adjustable stroke can be further configured as follows: several groups of first anti-slip grooves are evenly distributed on the outer periphery of the adjusting screw rod at intervals. Both ends of the first anti-slip grooves extend to the peripheral side of the adjusting screw rod, and the first anti-slip grooves can enhance the friction when holding the adjusting screw rod.

[0018] By adopting the above technical solution: through the first anti-slip grooves, when the adjusting mechanism adjusts the stroke of the cable, the friction when holding the adjusting screw rod can be increased, and the convenience of adjustment can be improved.

[0019] The above cable with adjustable stroke can be further configured as follows: several groups of second anti-slip grooves are evenly distributed on the outer periphery of the adjusting sleeve at intervals. One end of the second anti-slip grooves extends to the end face of the adjusting sleeve, and the second anti-slip grooves can enhance the friction when holding the adjusting sleeve.

[0020] By adopting the above technical solution: by evenly arranging the second anti-slip grooves on the outer periphery of the adjusting sleeve at intervals and cooperating with the first anti-slip grooves on the adjusting screw rod, the friction when grasping the adjusting mechanism is increased.

[0021] The above cable with adjustable stroke can be further configured as follows: at one end of the second cable sleeve away from the adjusting mechanism, there is a clamping mechanism, and the clamping mechanism can fix the second cable sleeve at the installation position.

[0022] By adopting the above technical solution: through the clamping mechanism, the first cable sleeve can be effectively fixed at the installation position to prevent the first cable sleeve from detaching from the cable.

[0023] The above cable with adjustable stroke can be further configured as follows: the clamping mechanism includes a third through hole, an annular groove and a clamping head. One end of the second cable sleeve away from the adjusting mechanism is fixedly connected to the third through hole, and a clamping buckle for clamping with the clamping head is provided on the outer periphery of the clamping head.

[0024] By adopting the above technical solution: through the annular groove, the second cable sleeve can be fixed at the installation position, and at the same time, the position of the second cable sleeve is kept stable by the mutual cooperation of the clamping joint and the clamping buckle.

[0025] The above-mentioned cable with adjustable stroke can be further set as: a fixing block is provided at one end of the cable close to the clamping joint, a fixing hole is provided on the fixing block, and the fixing block is clamped with the fixing component through the fixing hole.

[0026] By adopting the above technical solution: the cable is fixed at the designated position of the vehicle through the fixing block, so that the stroke of the cable is kept stable.

Detailed Embodiment

[0037] The technical solutions in the embodiments of the present utility model will be described clearly and completely below. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0038] As Figures 1 to 5 shown, an adjustable-stroke cable includes a cable 1 and a cable sleeve. The cable 1 is sleeved in the cable sleeve. The cable sleeve includes a first cable sleeve 2 and a second cable sleeve 3. An adjusting mechanism 4 is provided between the first cable sleeve 2 and the second cable sleeve 3. The adjusting mechanism 4 includes an adjusting screw 5 and an adjusting sleeve 6. The adjusting screw 5 is provided with an external thread, and the adjusting sleeve 6 is provided with an internal thread corresponding to the external thread. The adjusting sleeve 5 is threadedly connected to the adjusting screw 6. One end of the first cable sleeve 2 is connected to the end of the adjusting screw 5 away from the adjusting sleeve 6, and one end of the second cable sleeve 3 is connected to the end of the adjusting sleeve 6 away from the adjusting screw 5. By means of the adjusting screw 5 and the adjusting sleeve 6, when it is necessary to adjust the stroke of the cable, rotating the adjusting sleeve 6 one circle can make the adjusting sleeve 6 extend or shorten by the length of one pitch relative to the adjusting screw 5, thereby realizing the displacement of the cable sleeve relative to the cable 1, accurately adjusting the length of the exposed part of the cable. At the same time, the adjusting mechanism 4 adopts a structure in which the adjusting screw 5 and the adjusting sleeve 6 cooperate with each other. Compared with the prior art in which a housing and an adjusting core rod are used, the adjusting mechanism 4 provided by the present utility model has high adjustment accuracy, simple overall structure, fast assembly, strong practicability, and the adjusting mechanism 4 is small in size and can be applied to a variety of application scenarios, greatly improving the reuse ability of the cable.

[0039] As Figures 1 to 5 shown, a locking member 7 is provided on the adjusting screw 5. The locking member 7 can lock and limit the adjusting sleeve 6 on the adjusting screw 5. When it is necessary to adjust the stroke, loosen the locking member 7 and rotate the adjusting sleeve 6 to move along the axis direction of the adjusting screw 5; when the adjustment of the stroke is completed, tighten the locking member 7, and the adjusting sleeve 6 is limited by the locking member 7, effectively preventing the adjusting sleeve 6 from shifting on the adjusting screw 5 and maintaining a fixed position. The locking member 7 includes a locking nut. Tightening the locking nut can limit the adjusting sleeve 6 on the adjusting screw 5. Using the locking nut as the locking member 7, locking or loosening the adjusting sleeve 6 is relatively firm, and the operation is simpler, more convenient and faster.

[0040] As Figures 2 to 5In the adjusting mechanism 4 shown, one end of the adjusting screw 5 away from the adjusting sleeve 6 is provided with a first through hole 51 nested with the first cable sleeve 2, and one end of the adjusting sleeve 6 away from the adjusting screw 5 is provided with a second through hole 61 nested with the second cable sleeve 3. There is a diameter gradient between one end and the middle of the first through hole 51 and the second through hole 61, and the diameter of the end is larger. Through the first through hole 51 and the second through hole 61, the first cable sleeve 2 and the second cable sleeve 3 can be linked with the adjusting mechanism 4 and can be smoothly sleeved in the first through hole 51 and the second through hole 61 through the diameter gradient. A number of groups of first anti-slip grooves 52 are evenly distributed on the outer periphery of the adjusting screw 5 at intervals, and both ends of the first anti-slip grooves 52 extend to the peripheral side of the adjusting screw 5. Through the first anti-slip grooves 52, when the adjusting mechanism 4 adjusts the cable stroke, the friction during adjustment can be increased, improving the convenience of adjustment. A number of groups of second anti-slip grooves 62 are evenly distributed on the outer periphery of the adjusting sleeve 6 at intervals, and one end of the second anti-slip grooves 62 extends to the end face of the adjusting sleeve 6. By evenly arranging the second anti-slip grooves 62 on the outer periphery of the adjusting sleeve 6 at intervals and cooperating with the first anti-slip grooves 52 on the adjusting screw 5, the friction when grasping the adjusting mechanism 4 is increased.

[0041] As Figure 1 , Figure 6 , Figure 7 The clamping mechanism shown includes a third through hole 81, an annular groove 82 and a clamping head 83. A clamping buckle 9 that is clamped with the clamping head 83 is provided on the outer periphery of the clamping head 83. Through the clamping mechanism, the second cable sleeve 3 can be effectively fixed in the installation position to prevent the second cable sleeve 3 from detaching from the cable. Through the annular groove 82, the second cable sleeve 3 can be fixed in the installation position, and at the same time, the position of the second cable sleeve 3 is kept stable by the mutual cooperation of the clamping head 83 and the clamping buckle 9.

[0042] As Figure 1 , Figure 8 The fixing block 10 shown, the fixing block 10 is provided with a fixing hole 101, and the fixing block 10 can be clamped with the fixing component through the fixing hole 101 to fix the cable at the specified position and keep the stroke of the cable stable.

[0043] The above embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it cannot be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
