Description

Technical Field

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

[0002] Cable chains, composed of cable clamps, provide effective protection and support for cables. The chain structure, made up of multiple cable clamps connected together, forms a flexible whole that moves flexibly with the equipment. The cable chain has a cavity within which the cable is placed, preventing direct exposure and protecting it from damage caused by external impacts, friction, and pulling. During operation, the cable chain bears the drag force generated by the equipment, but the cable inside the chain, protected by the chain, is not directly subjected to these drag forces, thus reducing wear and breakage caused by stress and extending the cable's service life.

[0003] In the existing technology, the horizontal pin in the cable clamp is prone to problems due to rotation: when the bent part of the horizontal pin is aligned with the through groove on the clamp, the connection between the various parts of the cable clamp becomes unstable.

[0004] For example, patent CN214314355U discloses a magnetic anti-slip cable clamp for a coal mining machine used in a fully mechanized longwall face of an inclined coal seam. It includes C-shaped guard plates on the left and right sides, with the slots of the C-shaped guard plates facing each other. Upper and lower connecting cover plates are provided between the slots of the C-shaped guard plates. The upper and lower connecting cover plates are fixed to the C-shaped guard plates by a horizontal pin of the cable clamp. The C-shaped guard plates and the upper and lower connecting cover plates form a protective shell that wraps around the cable. The front and rear of the C-shaped guard plates are provided with hinge connection holes for the cable clamps to be connected in series. The outer surface of the C-shaped guard plate is provided with a groove for accommodating a strong magnet. The groove contains one or more strong magnets, which are fixed to the groove by bolts or sealant.

[0005] The aforementioned patent utilizes a strong magnet attached to the cable clamp to increase the sliding friction between the cable and the cable trough, preventing the cable from slipping and causing accidents. However, the inventors discovered during use that after prolonged use, the horizontal pin of the cable clamp would rotate due to vibration and other reasons. When the bent part at the end of the horizontal pin of the cable clamp aligns with the through groove on the C-shaped protective plate (the through groove is used for the bent part of the horizontal pin of the cable clamp to pass through when installing or removing the C-shaped protective plate), the connection between the C-shaped protective plate and the upper and lower connecting covers becomes unstable. There is a potential risk that the C-shaped protective plate and the upper and lower connecting covers will separate. If multiple sequentially connected cable clamps exhibit the above situation, the C-shaped protective plate and the upper and lower connecting covers will separate during the dragging process of the cable clamp.

[0006] For example, patent CN308593918S discloses a cable clamp for a coal mining machine, which has a similar structure to the aforementioned patent and also suffers from the same problem.

[0007] Therefore, a cable clamp needs to be developed to address the aforementioned defects. Utility Model Content

[0008] The purpose of this utility model is to provide a cable clamp that can effectively prevent the bent part of the horizontal shaft pin from aligning with the through groove on the cable clamp, thereby ensuring a firm connection between the various parts of the cable clamp.

[0009] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0010] This utility model discloses a cable clamp, comprising two spaced-apart end plates, with two connecting plates spaced apart between the two end plates. A transverse shaft pin is rotatably connected to each connecting plate. A groove is formed on one side of each end plate, and the bent portion of the transverse shaft pin contacts the bottom wall of the groove. The end plate also has a through groove communicating with the groove and allowing the bent portion to pass through. The clamp further includes:

[0011] A limiting block is used to prevent the bent portion from aligning with the through groove;

[0012] A snap-fit ​​component is located within the groove and is fixedly connected to the limiting block;

[0013] An anti-detachment component is installed on the snap-fit ​​part and snaps into the groove.

[0014] Optionally, the limiting block is located within the groove, and the limiting block is located between the bent portion and the through groove.

[0015] Optionally, one end of the limiting block is inserted into the through slot.

[0016] Optionally, the anti-detachment component includes a tension elastic component and a plug-in component. The plug-in component is fixed at both ends of the tension elastic component. The plug-in component passes through the snap-fit ​​component and is detachably connected to the side wall of the groove.

[0017] Optionally, the snap-fit ​​component has a relief groove on the side away from the bend, and the tension elastic component is located in the relief groove.

[0018] Optionally, the tension elastic component is an arc-shaped spring sheet.

[0019] Optionally, the plug-in component is a cylindrical structure with a non-circular cross-section, and a sliding hole matching the plug-in component is provided on the side wall of the groove and / or the side wall of the clearance groove, and the plug-in component is plugged into the sliding hole on the groove.

[0020] Optionally, the cross-section of the groove is non-circular, and the outer contour of the snap-fit ​​component matches the cross-section of the groove.

[0021] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0022] The use of snap-fit ​​components, anti-detachment components, and limit blocks prevents the bending part of the horizontal shaft pin from aligning with the through groove, thus ensuring a firm connection between the various parts of the cable clamp. This ensures a tight connection between the cable clamps and their components during cable chain operation, reducing the risk of malfunctions caused by loose connections and guaranteeing the stable operation of the cable drag chain system.

Detailed Implementation

[0032] The core of this utility model is to provide a cable clamp that can effectively prevent the bent part of the horizontal shaft pin from aligning with the through groove on the cable clamp, thereby ensuring a firm connection between the various parts of the cable clamp.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not 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.

[0035] Example 1

[0036] In one specific embodiment of this utility model, such as Figures 1-5 As shown, the device includes two spaced-apart end plates 100, with two connecting plates 200 spaced apart between them. A transverse shaft pin 300 is rotatably connected to each connecting plate 200. A groove 110 is formed on one side of each end plate 100, and the bent portion 310 of the transverse shaft pin 300 contacts the bottom wall of the groove 110. A through groove 120 is provided on each end plate 100, communicating with the groove 110 and allowing the bent portion 310 to pass through. This is prior art; for details, please refer to the patent documents cited in the background section. Further details are omitted here.

[0037] This utility model also includes:

[0038] The limiting block 400 is used to prevent the bent part 310 from aligning with the through groove 120, thereby ensuring a firm connection between the various parts of the cable clamp.

[0039] The snap-fit ​​component 500 is located in the groove 110 and is fixedly connected to the limiting block 400;

[0040] An anti-detachment component is installed on the snap-fit ​​part 500 and snaps into the groove 110 to prevent the snap-fit ​​part 500 and the limit block 400 from moving away from the bend 310.

[0041] In one specific embodiment of this utility model, such as Figure 4 and 5As shown, the limiting block 400 is located within the groove 110 and between the bent portion 310 and the through groove 120. Since the limiting block 400 is located between the bent portion 310 and the through groove 120, it blocks the bent portion 310, preventing it from aligning with the through groove 120, thus ensuring a secure connection between the various parts of the cable clamp.

[0042] In one specific embodiment of this utility model, such as Figures 1-5 As shown, the anti-detachment component includes a tension elastic component 600 and a plug-in component 700. The tension elastic component 600 has plug-in components 700 fixed at both ends. The plug-in component 700 passes through the snap-fit ​​component 500 and is detachably connected to the side wall of the groove 110.

[0043] In one specific embodiment of this utility model, such as Figures 1-5 As shown, the snap-fit ​​component 500 has a relief groove 510 on the side away from the bend 310, and the tension elastic component 600 is located in the relief groove 510. This prevents the tension elastic component 600 from protruding to the outside of the end plate 100, thus preventing it from being squeezed, collided, or hooked with external objects during the dragging of the cable chain.

[0044] In one specific embodiment of this utility model, such as Figures 1-5 As shown, the tension elastic component 600 is an arc-shaped spring sheet. Obviously, the tension elastic component 600 can also be a tension spring, or other elastic components with tension.

[0045] In one specific embodiment of this utility model, such as Figures 3-5 As shown, the insertion component 700 is a cylindrical structure with a non-circular cross-section (a regular hexagonal prism in the attached figure). Sliding holes matching the insertion component 700 are provided on the sidewalls of the groove 110 and / or the sidewalls of the clearance groove 510. The insertion component 700 is inserted into the sliding holes on the groove 110. Because the non-circular cylindrical structure of the insertion component 700 engages with the sliding holes, the insertion component 700 cannot rotate, thus preventing the tension elastic component 600 from rotating and thus preventing the tension elastic component 600 from protruding beyond the end plate 100. Through the insertion of the insertion component 700 into the sliding holes on the groove 110, the tension elastic component 600 causes the two insertion components 700 to tend to move away from each other, preventing the locking component 500 from dislodging from the groove 110.

[0046] In one specific embodiment of this utility model, such as Figure 2As shown, the cross-section of the groove 110 is non-circular, and the outer contour of the snap-fit ​​component 500 matches the cross-section of the groove 110. This design prevents the snap-fit ​​component 500 from rotating freely, thus preventing the limiting block 400 from rotating freely, effectively ensuring the limiting block 400's blocking effect on the bent portion 310. By implementing a foolproof design for the groove 110, as shown in the attached figure (interconnected rectangular and semi-circular grooves, or horseshoe shape), the installation orientation of the snap-fit ​​component 500 is relatively singular, ensuring that the limiting block 400 can be accurately positioned between the bent portion 310 and the through groove 120, improving convenience and reliability.

[0047] Principle: During the operation of the cable chain, when the equipment generates external forces such as vibration and tension to try to rotate the horizontal shaft pin 300, causing its bent part 310 to tend to align with the through groove 120, the limiting block 400, by virtue of its position between the bent part 310 and the through groove 120, directly blocks the movement of the bent part 310, prevents the two from aligning, and maintains the connection stability between the various parts of the cable clamp.

[0048] Example 2

[0049] The difference between this embodiment and Embodiment 1 is that the setting method of the limiting block 400 is different.

[0050] like Figure 6 and 7 As shown, one end of the limiting block 400 is inserted into the through groove 120. Since one end of the limiting block 400 is located inside the through groove 120, the limiting block 400 blocks the bending part 310, thereby preventing the bending part 310 from being aligned with the through groove 120, thus ensuring a firm connection between the various parts of the cable clamp and maintaining the stable operation of the cable chain system.

[0051] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably, and the embodiments can be combined with each other. For the apparatus disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to in the method section.

[0052] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
