Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a cable adjuster. Background Technology

[0002] A cable typically consists of two parts: a wire rope and a sleeve. In use, the wire rope is installed inside the sleeve, and external force can pull the wire rope, allowing it to move within the sleeve. The two ends of the sleeve are fixed to corresponding mating parts, while the two ends of the wire rope are fixedly connected to the driving and driven components, respectively. When the driving component moves, the wire rope drives the driven component, thus transmitting force and displacement from the driving component to the driven component. Since the lengths of the wire rope and sleeve are fixed, the maximum stroke of the cable cannot be changed, and this maximum stroke affects the transmission of displacement. In actual production and use, dimensional deviations due to processes or continuous stress causing the wire rope to elongate can affect the transmission of displacement, potentially leading to problems such as insufficient or no stroke.

[0003] The existing regulator consists of two axially movable connecting parts. One connecting part is fixed to the end of the wire rope, and the other connecting part is fixed to the end of the sleeve. By adjusting the relative position of the two connecting parts, the relative length of the wire rope and the sleeve can be adjusted. After adjustment, the two connecting parts are then fixed. Typically, two nuts are tightened together to ensure structural stability. However, this structure requires tools for implementation and still carries the risk of loosening, which could affect displacement transmission. Utility Model Content

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, the terms "first" and "second" are merely used to distinguish between different terms in description and do not have any special meaning.

[0026] Please see Figure 1 and Figure 2 As shown, this embodiment provides a cable adjuster. The cable includes a sleeve and a steel wire rope passing through the sleeve. The end of the sleeve is connected to a sleeve cover 1, and the end of the steel wire rope extends out of the sleeve cover 1 and is connected to a housing 2.

[0027] The cable adjuster includes a connecting bolt 3 and a self-locking housing 4. The first end of the connecting bolt 3 is inserted into the housing 2 and threadedly connected to the housing 2. The second end of the connecting bolt 3 is fitted onto the sleeve cover 1 and fixedly connected to the sleeve cover 1. The surface of the second end of the connecting bolt 3 and the surface of the housing 2 are respectively set as prism portions 5 of the same size. The self-locking housing 4 is provided with a prism inner cavity adapted to the prism portion 5, so that the self-locking housing 4 can be fitted onto the housing 2 and the connecting bolt 3 and move axially. The self-locking housing 4 is detachably connected to the housing 2 and / or the connecting bolt 3.

[0028] Therefore, it can be quickly adjusted manually without the need for additional tools, which improves adjustment efficiency and convenience, ensures structural stability, and meets the needs of cable stroke adjustment.

[0029] The connecting bolt 3 and the entire surface of the housing 2 can be set as prisms 5, or a portion of the surface can be set as protruding prisms 5, both of which can meet the design requirements.

[0030] Optionally, the self-locking housing 4 is provided with a claw 6 and the housing 2 is provided with a groove 7. When the claw 6 and the groove 7 engage and lock, the axial travel of the self-locking housing 4 is locked.

[0031] Thus, the locking claw 6 and the slot 7 work together to achieve a fixed connection between the self-locking housing 4 and the housing 2. Furthermore, since the prism cavity of the self-locking housing 4 restricts the rotation of the housing 2 and the connecting bolt 3, the relative position of the connecting bolt 3 and the housing 2 remains stable, thereby locking the cable stroke and making the structure more reliable.

[0032] Optionally, a number of claws 6 extend from the end of the locking housing 4 and are evenly distributed around the circumference, and the slots 7 are opened around the circumference of the housing 2.

[0033] Thus, the precise cooperation between the claw 6 and the slot 7 ensures a stable and detachable connection between the limiting self-locking shell 4 and the shell 2. The number and distribution of the claw 6 can be adjusted according to actual needs.

[0034] Optionally, the first end of the connecting bolt 3 is provided with an external thread 8, and the end of the housing 2 is provided with a threaded hole that mates with the external thread 8.

[0035] Therefore, by connecting bolt 3 to housing 2 with threads, the relative distance between connecting bolt 3 and housing 2 can be adjusted, thereby realizing the function of adjusting the cable stroke.

[0036] Optionally, a socket 9 is provided on the second end of the connecting bolt 3, and a clip 10 is provided on the end of the sleeve cover 1 to engage with the socket 9. Thus, the precise engagement between the clip 10 and the socket 9 ensures a stable connection between the connecting bolt 3 and the sleeve cover 1, further improving the overall stability and adjustment accuracy of the cable adjuster.

[0037] In this embodiment, the prism part 5 is exemplified by a hexagonal prism shape, and the rotation adjustment angle of the connecting bolt 3 relative to the housing 2 is 60° or an integer multiple of 60°.

[0038] Therefore, the hexagonal prism design ensures that the connecting bolt 3 can be accurately positioned during rotation, making it easy for the operator to quickly identify and adjust it. On this basis, the more edges the prism part 5 has, the more precise the adjustment angle, the more flexible the operation, and the more adaptable it is to different adjustment needs, ensuring the accuracy and stability of the cable stroke adjustment.

[0039] Optionally, the sleeve cap 1, housing 2, connecting bolt 3, and limiting self-locking housing 4 are all plastic parts.

[0040] Therefore, using plastic instead of metal reduces the overall weight and production costs, while ensuring good wear resistance and corrosion resistance, extending service life, and improving the product's cost-effectiveness.

[0041] Specific adjustment process: 1) Move the self-locking housing 4 axially so that it is only fitted onto the connecting bolt 3, and the self-locking housing 4 is disengaged from the housing 2; 2) Adjust the connecting bolt 3 to rotate relative to the housing 2 at a set angle to achieve the expected stroke; 3) Move the self-locking housing 4 axially again so that it is simultaneously fitted onto the connecting bolt 3 and the housing 2, and the pawl 6 and the slot 7 engage to lock the axial stroke of the self-locking housing 4; 4) Repeat the above steps when further adjustment is needed.

[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
