[0030] The specific embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0031] In the description of the present disclosure, it is necessary to understand that the terms "upper", "lower", "inside" and "outside" etc. indicating orientation or positional relationships are defined based on the drawing directions shown in the accompanying drawings, and are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, and a specific orientation structure and operation, and therefore cannot be understood as a limitation on the present disclosure.

[0032] In the present disclosure, it should be noted that the terms used, such as "first", "second", etc., are used to distinguish one element from another element, and do not have order and importance. In addition, in the description with reference to the drawings, the same number in different drawings represents the same element.

[0033] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0034] As mentioned above, the cable will experience long-distance friction when turning. After running for a period of time, the cable will experience long-distance bending deformation and even large-area insulation wear.

[0035] In view of this, if Figures 1 to 6 As shown, the present application provides a steering protection device for a cable, which can be applied to a door machine to achieve steering and protection of a cable 110 of the door machine. The cable 110 has a first end and a second end opposite to each other, and the steering protection device 100 includes a steering device 10 and a fixing device 20, the fixing device 20 and the steering device 10 are suitable for being arranged along the length direction of the cable 110, the steering device 10 includes a first side and a second side arranged opposite to each other, the second side is closer to the fixing device 20 than the first side, the first side of the steering device 10 is provided with a steering structure 11, the steering structure 11 is suitable for guiding the first end of the cable 110 to achieve steering of the cable 110, and the fixing device 20 is suitable for fixing the portion of the cable 110 located between the second side of the steering device 10 and the second end of the cable 110. A fixing device 20 and a steering device 10 are provided on the cable 110. The steering device 10 can guide the first end of the cable 110 to turn, thereby realizing the steering of the cable 110. The fixing device 20 can fix the portion of the cable 110 between the steering device 10 and the second end of the cable 110, which is beneficial to prevent the cable 110 from being dragged or damaged when turning.

[0036] In the present disclosure, the steering structure 11 is used to guide the steering of the cable 110. The first end of the cable 110 refers to the end of the cable 110 that needs to be steered, and the second end of the cable 110 refers to the end away from the first end in the length direction of the cable 110. When the steering structure 11 guides the first end of the cable 110 to steer, if the second end of the cable 110 is not fixed, it may be dragged, flipped (bent), and other problems may occur. After long-term use, the second end of the cable 110 may be bent and deformed or even have a large area of ​​insulation wear. Therefore, a fixing device 20 is provided to fix the portion of the cable 110 between the steering device 10 and the second end of the cable 110, so as to fix the position of the portion of the cable 110, thereby preventing the cable 110 from long-distance insulation wear and bending deformation, thereby reducing the risk of shortening the service life of the cable 110 and reducing the probability of safety hazards such as the risk of electric shock to operators.

[0037] It can be understood that the steering protection device 100 for the cable 110 provided in the present disclosure can be applied not only to door machines, but also to any other electrical equipment suitable for adopting the steering protection device 100, and the present disclosure does not limit this.

[0038] In this disclosure, Figures 1 to 6 As shown, the distance between the fixing device 20 and the second side of the steering device 10 can be less than or equal to 30 cm, that is, the distance between the fixing device 20 and the second side of the steering device 10 in the length direction of the cable 110 can be less than or equal to 30 cm. When the first end of the cable 110 is turned, the portion of the cable 110 closer to the first end is more susceptible to the influence of the turning (such as drag friction, flip bending, etc.), so the distance between the fixing device 20 and the second side of the steering device 10 is 30 cm. This distance ensures that the fixing device 20 and the steering device 10 can be easily installed, and at the same time, the fixing device 20 is as close to the second side of the steering device 10 as possible, so that the fixing device 20 can fix the portion between the first end and the second end of the cable 110 that is closer to the first end, so that the fixing device 20 is more conducive to preventing the cable 110 from being worn and deformed.

[0039] In some embodiments, Figures 1 to 5As shown, when installing the steering protection device 100, the distance between one end of the fixing device 20 and the second side of the steering device 10 can be set to 0 (that is, the fixing device 20 and the steering device 10 are connected in one piece), so that the fixing device 20 can be installed at the position where the cable 110 needs to be fixed at the same time. Such a setting can facilitate the installation of the steering protection device 100. In addition, the distance between one end of the fixing device 20 and the second side of the steering device 10 is set to 0, which satisfies the requirement of making the fixing device 20 as close to the second side of the steering device 10 as possible, so that the position of the fixing device 20 fixing the cable 110 is more suitable, which is more conducive to preventing the cable 110 from being worn and deformed.

[0040] The connection between one end of the fixing device 20 and the second side of the steering device 10 may be made by welding.

[0041] In some embodiments, Figure 6 As shown, when installing the steering protection device 100, the fixing device 20 and the second side of the steering device 10 can be separated and arranged, and the separation distance is not greater than 30 cm. In this way, the fixing device 20 and the steering device 10 can be installed separately, which is convenient for application on foundation surfaces with corners and interference structures, for example, and the split installation is also convenient for carrying.

[0042] In this disclosure, Figures 1 to 6 As shown, the fixing device 20 may include a first clamping plate 21 and a second clamping plate 22 connected to each other, and a clamping groove 23 is formed between the first clamping plate 21 and the second clamping plate 22, and the clamping groove 23 is used to fix the cable 110. Such a configuration can facilitate the fixing device 20 to install and clamp the cable 110. And because the clamping groove 23 has a space for accommodating the cable 110, it can be suitable for thicker cables 110.

[0043] In some embodiments, the opposing surfaces of the first clamping plate 21 and the second clamping plate 22 can be set as planes, and the cable 110 is clamped between the two planes. The cable 110 can be clamped by locking the two ends of the first clamping plate 21 and the second clamping plate 22. Such a setting can simplify the process of manufacturing the first clamping plate 21 and the second clamping plate 22, and can be suitable for cables 110 with smaller thickness.

[0044] In this disclosure, Figures 1 to 6As shown, the first clamping plate 21 and the second clamping plate 22 are arranged in the up-down direction, the second clamping plate 22 is located above the first clamping plate 21, and the lower surface of the second clamping plate 22 may be provided with a groove 221, the size of the groove 221 in the width direction of the cable 110 is greater than or equal to the width of the cable 110, and the depth of the groove 221 is less than or equal to the thickness of the cable 110, the first clamping plate 21 and the second clamping plate 22 are detachably connected, and the groove 221 and the upper surface of the first clamping plate 21 jointly define a clamping groove 23. The up-down direction refers to the direction perpendicular to the wide surface of the cable 110. In this way, the clamping groove 23 can accommodate the cable 110 and can directly clamp the cable 110.

[0045] A groove 221 is provided on the lower surface of the second clamping plate 22 , which can be suitable for cables 110 of various sizes. That is, when the width of the cable 110 becomes wider, the second clamping plate 22 with a wider groove 221 can be replaced to be suitable for the wider cable 110 .

[0046] In some embodiments, the groove 221 can be set on the upper surface of the first clamping plate 21, and the lower surface of the second clamping plate 22 is a plane. Then, the groove 221 and the lower surface of the second clamping plate 22 jointly define a clamping groove 23. With such a setting, the cable 110 can be pre-limited when being placed, thereby preventing the cable 110 from shifting on the upper surface of the first clamping plate 21.

[0047] In this disclosure, Figure 1 As shown, the inner wall of the groove 221 may be provided with a buffer pad 30. This arrangement can protect the outer wall of the cable 110 and also make the clamping effect of the fixing device 20 better.

[0048] In some embodiments, a buffer pad 30 may be provided on the surface of the first clamping plate 21 , or the buffer pad 30 may be wrapped around the portion where the cable 110 is fixed to the fixing device 20 .

[0049] The buffer pad 30 may be configured to protect the rubber.

[0050] In this disclosure, Figures 1 to 6 As shown, in order to facilitate the installation of the fixing device 20 , the first clamping plate 21 can be connected to the foundation surface by a first bolt 51 , and the first clamping plate 21 and the second clamping plate 22 are connected by a second bolt 52 .

[0051] In some embodiments, the first clamping plate 21 can be buried in the foundation surface so that the upper surface of the first clamping plate 21 is flush with the foundation surface after construction is completed. This arrangement can prevent the two sides of the cable 110 passing through the fixing device 20 from being bent.

[0052] The foundation surface refers to the surface where the cable 110 is arranged.

[0053] In one embodiment of the present disclosure, Figures 4 to 6 As shown, in order to ensure a stable connection between the second clamping plate 22 and the first clamping plate 21 , the number of the second bolts 52 can be at least four. The second clamping plate 22 is a rectangular plate, and the four corners of the second clamping plate 22 are all provided with second bolts 52 .

[0054] In another embodiment of the present disclosure, Figures 1 to 3 As shown, the number of the second bolts 52 is at least two, the second clamping plate 22 includes a rectangular portion 222 and two connecting portions 223, the two connecting portions 223 are arranged on one side of the rectangular portion 222 in the first direction, and the two connecting portions 223 are arranged at intervals in the second direction, the second direction is perpendicular to the first direction, the first clamping plate 21 is provided with two lugs 211, each connecting portion 223 is hinged to the corresponding lug 211, and the two second bolts 52 are penetrated at the position of the rectangular portion 222 on the other side of the first direction. The second clamping plate 22 is rotatably connected to one side of the first clamping plate 21, which can facilitate the installation of the second clamping plate 22, that is, it is only necessary to install the second bolt 52 on the other side of the second clamping plate 22.

[0055] In this embodiment, if Figures 1 to 3 As shown, the two lugs 211 are rotationally connected to the two connecting parts 223, thereby completing the connection between the second clamping plate 22 and the first clamping plate 21 on one side, and the second clamping plate 22 is connected to the other side of the first clamping plate 21 using the second bolt 52, thereby completing the connection between the first clamping plate 21 and the second clamping plate 22.

[0056] The first direction may be parallel to the length direction of the cable 110 or perpendicular to the length direction of the cable 110 , which is not limited in the present disclosure.

[0057] In this disclosure, Figures 1 to 6As shown, the steering device 10 may also include a support frame 12 and a base plate 13, the lower end of the support frame 12 is connected to the base plate 13, the support frame 12 is used to support the steering structure 11, the base plate 13 is connected to the foundation surface through the third bolt 53, a limit rod 14 is provided on the second side of the steering device 10, the limit rod 14 is located above the base plate 13, and is used to limit the position of the cable 110 in the up and down direction, and the steering structure 11 includes an annular plate, and the convex surface of the annular plate faces the first side of the steering device 10. The convex surface of the annular plate faces the first side of the steering device 10, and the first side of the steering device 10 and the first end of the cable 110 are on the same side. The steering structure 11 is used to guide the cable 110 to turn (the convex surface of the annular plate guides the cable 110 to turn), that is, it is necessary to support the weight of the turning part of the cable 110, so the support frame 12 is provided to support the steering structure 11 and thus support the cable 110. Among them, the steering device 10 is set in a ring shape to ensure that there is no large bend when the cable 110 turns, so as to prevent damage to the cable 110.

[0058] In this disclosure, Figure 2 As shown, the bottom plate 13 may include a first bottom plate 131 and a second bottom plate 132 arranged at intervals, and a wire passage for the cable 110 to pass through is configured between the first bottom plate 131 and the second bottom plate 132, and the width of the wire passage is set to be greater than the width of the cable 110. The purpose of constructing the wire passage is to facilitate the lower end of the steering device 10 to accommodate the cable 110, so as to facilitate the installation of the steering device 10. For example, when the steering device 10 is installed after the cable 110 is laid, the steering device 10 can be directly mounted on the position where the cable 110 needs to be turned, and the cable 110 does not need to be first passed through the steering device 10 and then laid.
