Description

Technical Field

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

[0002] Common cable systems mainly consist of steel wires and sleeves, with the operating mechanism and actuator connected to the two ends of the steel wire rope, respectively. Driven by the operating mechanism, the steel wire rope moves within the sleeve, transmitting force and displacement to the actuator. When the operating mechanism is released, the steel wire rope resets under the action of a reset component at either the actuator or the operating mechanism.

[0003] The reset element is generally a spring. Taking the reset element located at the actuator as an example, the spring is sleeved on the wire rope and located between the sleeve end and the connector on the wire rope that connects to the actuator. When the operating mechanism pulls the cable, the distance between the sleeve end and the connector decreases, and the spring is compressed. When the operating mechanism releases, the spring pushes the connector away from the sleeve end under its own elastic force, thus achieving reset.

[0004] In the above structure, the spring is not reliably limited, and during the compression and deformation process, there are abnormal noises and unstable forces, and the spring may even deform, affecting the reset effect. Utility Model Content

[0005] The purpose of this utility model is to provide a cable reset structure and cable to solve the problems mentioned in the background art and ensure the normal function of the cable.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cable reset structure includes a sleeve and a steel wire rope passing through the sleeve. The sleeve has a sleeve cap at one end, and the end of the steel wire rope extends out of the sleeve cap and is provided with a connector. A spring is sleeved on the steel wire rope extending out of the sleeve cap. One end of the spring is fixed to the sleeve cap, and the other end of the spring is fixed to the connector. The inner diameter surface of the spring does not contact the surface of the steel wire rope.

[0008] As an alternative, the sleeve cap is provided with a flange, and the end of the spring is hung on the flange.

[0009] As an alternative, the connector head is provided with a groove, and the end of the spring is clamped in the groove.

[0010] As an alternative, the connector is cylindrical, and the axis of the connector is perpendicular to the axis of the wire rope.

[0011] As an alternative, the inner diameter of the spring is 2 to 3 times the diameter of the wire rope.

[0012] On the other hand, the present invention adopts the following technical solution:

[0013] A cable employing the aforementioned cable reset structure.

[0014] The beneficial effects of this utility model are:

[0015] Compared with existing technologies, this cable reset structure stabilizes the force value, eliminates abnormal noise, avoids deformation, and ensures the reset function of the spring by fixing the spring and reducing its friction. The cable structure made in this way is more stable and has a longer service life. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0020] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. 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.

[0023] Furthermore, the terms "first" and "second" are merely used to distinguish between different terms in description and do not have any special meaning.

[0024] Please see Figure 1 As shown, this embodiment provides a cable reset structure, including a sleeve 1 and a steel wire rope 2 passing through the sleeve 1. The end of the sleeve 1 is provided with a sleeve cap 3. The end of the steel wire rope 2 extends out of the sleeve cap 3 and is provided with a connector 4. A spring 5 is sleeved on the steel wire rope 2 extending out of the sleeve cap 3. One end of the spring 5 is fixed to the sleeve cap 3, and the other end of the spring 5 is fixed to the connector 4. The inner diameter surface of the spring 5 does not contact the surface of the steel wire rope 2.

[0025] Therefore, by fixing the spring 5, the friction of the spring 5 can be reduced, the force value can be stabilized, abnormal noise can be eliminated, deformation can be avoided, and the reset function of the spring 5 can be guaranteed.

[0026] Optionally, the sleeve cap 3 is provided with a flange 6, and the end of the spring 5 is hung on the flange 6. Further, a through hole can be provided on the flange 6 to facilitate hooking and fixing of the spring 5. In specific applications, the size or shape of the sleeve cap 3 can be adjusted to accommodate different diameters of the wire rope 2 and the tension requirements of the spring 5.

[0027] Optionally, the connector 4 is provided with a groove 7, and the end of the spring 5 is clamped in the groove 7, thereby limiting and fixing the end of the spring 5 through the groove 7.

[0028] Furthermore, the connector 4 is cylindrical, and its axis is perpendicular to the axis of the wire rope 2. This arrangement facilitates the fixing of the end of the axial spring 5, and the connector 4 maintains stable and reliable mechanical properties whether connected to the operating mechanism or the actuator, ensuring accurate and error-free reset action.

[0029] When the spring 5 is installed between the sleeve cover 3 and the connector 4 of the operating mechanism, the spring 5 is stretched when the operating mechanism pulls the cable; when the operating mechanism releases, the spring 5 pulls the connector 4 of the operating mechanism toward the sleeve cover 3 under its own elastic force, thus achieving reset.

[0030] When the spring 5 is installed between the sleeve cover 3 and the connector 4 of the actuator, the spring 5 is compressed when the operating mechanism pulls the cable; when the operating mechanism releases, the spring 5 pushes the connector 4 of the actuator away from the sleeve cover 3 under its own elastic force, thus achieving reset.

[0031] Optionally, the inner diameter of the spring 5 is 2 to 3 times the diameter of the wire rope 2 to ensure that the spring 5 does not contact the surface of the wire rope 2 during the tension, compression and reset processes, thereby effectively reducing frictional loss, eliminating abnormal noise, extending service life, and if the spring 5 is excessively deformed, the wire rope 2 can still provide a certain guiding effect on the spring 5.

[0032] Based on this, this embodiment also provides a cable that employs the aforementioned cable reset structure. As a result, the manufactured cable structure is more stable and has a longer service life.

[0033] 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.
