Description

Technical Field

[0001] This utility model relates to the field of power supply device technology, and in particular to a power cord anti-pull fixing device. Background Technology

[0002] In the power supply field, various electrical devices are typically equipped with electrical components such as lighting and temperature control. These components require power supply via power cords, and the stable operation of the power cords directly affects the normal use of the equipment and electrical safety. Power cords are susceptible to accidental pulling forces during equipment installation, use, or maintenance. If the pulling force is applied directly to the power cord body or interface, it may cause internal wire breakage, insulation damage, or even short circuits, leakage, and other safety hazards. Therefore, it is essential to protect power cords from pulling forces.

[0003] For example, the invention with application number CN202411100737.0 discloses a power cord anti-pull mechanism and an industrial six-axis robot, including a power cord, a power box, and an anti-pull device. One end of the power cord is provided with a power plug, and the other end is used to connect to equipment that requires power to operate. A power socket is provided on one side of the power box, wherein the power plug can be plugged into the power socket to connect the power. The anti-pull device is provided on the power box, which includes a fastening device and a power device. The fastening device is used to fasten the power plug after it is plugged into the power socket to prevent pulling between the power cord and the power socket. The power device is used to provide power to the fastening device to fasten the power plug.

[0004] The aforementioned existing technology uses a method of securing the power plug to prevent pulling between the power cord and the power socket. However, there is no buffer between the power cord and the power socket. When the device is moved accidentally or pulled by external force, the instantaneous stress will be concentrated at the connection between the plug and the socket, causing the plug to loosen or even fall off. At the same time, due to the lack of a buffer mechanism, the base of the power cord is subjected to rigid tension for a long time, which can easily lead to damage such as cracking of the outer sheath and breakage of the internal wires, thus shortening the service life of the power cord.

[0005] Therefore, this application proposes a power cord anti-pull fixing device. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a power cord anti-pull fixing device, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A power cord anti-pull fixing device includes a cable and a rectangular cover. The rectangular cover is hollow, with a circular hole through its axis, through which the cable moves. A limiting component for preventing cable pull is installed inside the rectangular cover cavity. The limiting component includes a first clamping unit and a second clamping unit, which clamp onto the outer wall of the cable. The first clamping unit includes a first clamping seat and a first clamping cover, and the second clamping unit includes a second clamping seat and a second clamping cover. A fixing unit is installed between the first clamping unit and the rectangular cover cavity, and the fixing unit includes a first crossbar and a fixing seat. A compression unit is installed between the second clamping unit and the rectangular cover cavity, and the compression unit includes a sliding groove, a guide rod, and a compression spring. Second crossbars are fixedly installed on both sides of the second clamping seat. When the cable is pulled, the second crossbars move to compress the compression spring.

[0009] According to the power cord anti-pull fixing device, the first clamp seat and the first clamp cover are fixed to the outer periphery of the cable by screws, and the second clamp seat and the second clamp cover are fixed to the outer periphery of the cable by screws.

[0010] According to the power cord anti-pull fixing device, the cable has an arc-shaped section between the first clamp seat and the second clamp seat, and the first clamp seat and the second clamp seat are respectively fixedly installed on the side that are close to each other.

[0011] According to the power cord anti-pull fixing device, a tension spring is connected between the first hanging plate and the second hanging plate. There are two sets of tension springs, and the two sets of tension springs are parallel to each other.

[0012] According to the power cord anti-pull fixing device, the first clamp seat is fixedly connected to the first crossbar on both sides near the rectangular cavity. The fixing seat is fixedly installed on both sides inside the rectangular cavity. The fixing seat is U-shaped. The first crossbar can be movably engaged in the U-shaped groove of the corresponding fixing seat. A fixing screw is provided between the fixing seat and the first crossbar. The first crossbar is fixedly connected to the corresponding fixing seat through the fixing screw.

[0013] According to the power cord anti-pull fixing device, sliding grooves are also fixedly installed on both sides of the rectangular cover cavity, and the end of the second crossbar away from the second clamp seat is movably engaged in the sliding groove cavity.

The guide rod and the corresponding second crossbar are perpendicular to each other. The compression spring is sleeved on the outer wall of the guide rod and is located between the second crossbar and the slide groove.

[0015] This utility model provides a power cord anti-pull fixing device. It has the following beneficial effects:

[0016] (1) This application sets up components such as a first clamping unit, a second clamping unit, a first crossbar, a fixed seat and a fixing screw. The first clamping seat and the first clamping cover, and the second clamping seat and the second clamping cover are fixed to the outer periphery of the cable by screws. Combined with the engagement of the first crossbar and the fixed seat and the tightening effect of the fixing screw, the cable is stably positioned in the rectangular cover, avoiding uneven force caused by the unrestrained shaking of the cable, ensuring the reliable clamping of the cable by the limiting component, and enhancing the overall structural stability of the device.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-2 As shown, this utility model is a power cord anti-pull fixing device, including a cable 11 and a rectangular cover 10. The rectangular cover 10 is hollow, and a circular hole is opened through the axis of the rectangular cover 10. The cable 11 moves through the circular hole to realize the cable 11 passing through the device. A limiting component for preventing the cable 11 from being pulled is provided inside the cavity of the rectangular cover 10. The limiting component can effectively constrain the cable 11 through clamping and force buffering. The limiting component includes a first clamping unit 13 and a second clamping unit 14, which clamp the cable 11 respectively. The outer wall, through clamping force, limits the cable 11. The first clamping unit 13 includes a first clamping seat 15 and a first clamping cover 16. The second clamping unit 14 includes a second clamping seat 17 and a second clamping cover 18. The first clamping seat 15 and the first clamping cover 16 are fixed to the outer periphery of the cable 11 by screws. The second clamping seat 17 and the second clamping cover 18 are fixed to the outer periphery of the cable 11 by screws, so as to achieve stable clamping of the cable 11 at a specific position, ensure the basic positioning of the cable 11 within the rectangular cover 10, and avoid the problem of uneven force caused by the cable 11 swinging randomly in an unrestrained state.

[0027] like Figure 3 As shown, the cable 11 has an arc-shaped section between the first clamp seat 15 and the second clamp seat 17. This arc-shaped section can provide deformation buffer space when subjected to force. The first clamp seat 15 and the second clamp seat 17 are respectively fixedly installed on the side close to each other. The first clamp seat 19 and the second clamp seat 17 are connected by hooks to the first clamp seat 19 and the second clamp seat 20. There are two sets of tension springs 21. The two sets of tension springs 21 are parallel to each other and can evenly distribute the tension. When the cable 11 is pulled, the tension springs 21 will be stretched and generate a reverse elastic force, which effectively disperses and buffers the tension force, reduces the strength of the tension force directly acting on the cable 11 body, and reduces the risk of the cable 11 being pulled apart.

[0028] like Figure 4As shown, a fixing unit is provided between the first clamping unit 13 and the cavity of the rectangular cover 10. The fixing unit includes a first crossbar 22 and a fixing seat 24. The first clamping seat 15 is fixedly connected to the first crossbar 22 on both sides near the cavity of the rectangular cover 10. The fixing seat 24 is fixedly installed on both sides of the cavity of the rectangular cover 10. The fixing seat 24 is U-shaped. The first crossbar 22 can be movably engaged in the U-shaped groove of the corresponding fixing seat 24 to achieve initial positioning. A fixing screw 25 is provided between the fixing seat 24 and the first crossbar 22. The first crossbar 22 is fixedly connected to the corresponding fixing seat 24 through the fixing screw 25, thereby firmly fixing the first clamping unit 13 in the cavity of the rectangular cover 10. This prevents the first clamping unit 13 from shifting or loosening during the force process, ensuring the positional stability of the first clamping unit 13 in the limiting assembly, ensuring that its clamping and limiting effect on the cable 11 will not be weakened due to its own displacement, and enhancing the overall stability of the device structure.

[0029] like Figure 5 As shown, a compression unit is provided between the second clamping unit 14 and the cavity of the rectangular cover 10. The compression unit includes a sliding groove 26 for guiding and limiting, a guide rod 27 for guiding and supporting, and a compression spring 28 for elastic buffering. The second crossbar 23 is fixedly installed on both sides of the second clamping seat 17. When the cable 11 is pulled, the second crossbar 23 moves to compress the compression spring 28. The sliding groove 26 is also fixedly installed on both sides of the cavity of the rectangular cover 10. The sliding groove 26 provides a sliding track for the second crossbar 23. The end of the second crossbar 23 away from the second clamping seat 17 is movably engaged in the cavity of the sliding groove 26. The guide rod 27 is fixedly installed in the cavity of the corresponding slide groove 26. The ends of the two sets of second crossbars 23 away from the second clamp seat 17 are all provided with movable holes. The guide rod 27 moves through the movable holes of the corresponding second crossbars 23. The guide rod 27 and the corresponding second crossbars 23 are perpendicular to each other to ensure the stability of the movement direction of the second crossbars 23. The compression spring 28 is sleeved on the outer wall of the guide rod 27 and is located between the second crossbars 23 and the slide groove 26. When the cable 11 is pulled, the second crossbar 23 moves along the slide groove 26 and compresses the compression spring 28. The guide rod 27 ensures the stability of the movement direction of the second crossbar 23 and avoids the cable 11 from being deviated by force. At the same time, the compression spring 28 further buffers the pulling force through the reverse elastic force generated by compression, forming a double buffer with the tension spring 21, which significantly improves the anti-pull protection effect of the device on the cable 11 and extends the service life of the cable 11.

[0030] The working principle of this utility model power cord anti-pull fixing device is as follows:

[0031] First, the cable 11 is movably passed through the circular hole at the axis position of the rectangular cover 10. Then, the first clamp seat 15, the first clamp cover 16, the second clamp seat 17, and the second clamp cover 18 are fixed to the outer circumference of the cable 11 by screws. The clamping force of the two sets of clamp units on the cable 11 realizes the basic positioning of the cable 11 within the rectangular cover 10, avoiding the problem of uneven force caused by the cable 11 swinging freely in an unrestrained state. The first clamp unit 13 is engaged with the fixed seat 24 through the first crossbar 22, and the fixing screw 25 fixes the first crossbar 22 to the first crossbar 24.

[0032] Secondly, the arc-shaped section reserved between the first clamp seat 15 and the second clamp seat 17 of the cable 11 provides space for deformation buffer when the cable 11 is subjected to force. The first hanging plate 19 and the second hanging plate 20 are fixedly installed on the first clamp seat 15 and the second clamp seat 17 respectively. Two sets of parallel tension springs 21 are connected by hooks. When the cable 11 is subjected to a slight tension force, the arc-shaped section deforms first. At the same time, the tension springs 21 are stretched and generate a reverse elastic force, which initially disperses and buffers the tension force, reducing the strength of the tension force directly acting on the cable 11 body.

[0033] Finally, when the cable 11 is subjected to a large pulling force, the second clamp unit 14 moves with the cable 11, causing the second crossbars 23 on both sides to slide along the cavity of the slide groove 26. The guide rod 27 passes through the movable hole of the second crossbar 23 to ensure that the movement direction of the second crossbar 23 is stable and to prevent the cable 11 from deviating from the force. At the same time, the second crossbar 23 moves to compress the compression spring 28. The reverse elastic force generated by the compression spring 28 further buffers the pulling force, forming a double elastic buffer with the tension spring 21, improving the anti-pull protection effect of the device on the cable 11 and extending the service life of the cable 11.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
