Description

Technical Field

[0001] The utility model relates to the technical field of wire troughs, in particular to a wire trough device for high and low voltage switch cabinets. Background Art

[0002] High and low voltage switchgear refers to a device used to connect high voltage cables or low voltage cables. Some external cables need to be connected to the cabinet for use. However, since the switch cabinet itself has many cables, it is easy to make the external cables difficult to distinguish from the cabinet cables after they are connected, causing inconvenience in replacing external cables later. Therefore, it is necessary to use a cable trough device to classify and locate the cables to ensure the accuracy and beauty of the wiring.

[0003] According to a publicly disclosed wire duct device for high and low voltage switchgear (Announcement No.: CN214255521U), in the above application, when the external cables are placed in the groove of the card plate, the card plate will slide in the second and third slide grooves due to the entry of the cables, thereby achieving the effect of placing multiple external cables. In addition, the tension spring design is used to ensure that the card plate can stabilize the cables after the external cables are placed, avoiding the problem of cable entanglement and improving the efficiency of cable replacement in the later stage.

[0004] However, in actual use of the above-mentioned equipment, since not all cables are clamped at the same time during the wiring process, the cables that are clamped first are prone to being touched or dragged during the subsequent wiring process, causing the risk of displacement, thereby affecting the stability of the already laid cables. In view of this, we have proposed a cable duct device for high and low voltage switchgear. Utility Model Content

[0005] The purpose of the utility model is to provide a wire duct device for high and low voltage switch cabinets to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a wire trough device for a high- and low-voltage switch cabinet, comprising a cabinet body, a control panel fixedly mounted on the inner wall of the cabinet body, a wire trough box fixedly mounted on the side of the control panel, a cover plate detachably mounted on the top inner wall of the wire trough box, and a torsion assembly disposed inside the wire trough box;

[0007] In which, the torsion assembly includes a fixed column, the bottom end of the fixed column is fixedly installed on the bottom inner wall of the wire trough box, the top surface of the fixed column is rotatably connected to the torsion sleeve, the top outer wall of the fixed column is provided with a coil spring, the upper surface of the torsion sleeve is fixedly installed with a fixed plate, the outer wall of the fixed plate close to the torsion sleeve is fixedly installed with an arc-shaped block, and the side wall of the arc-shaped block is fixedly installed with an arc-shaped sheet.

[0008] Preferably, the torsion sleeve is arranged in a bottle cap shape, and the two ends of the coil spring are fixedly connected to the arc-shaped outer wall of the fixed column and the top inner surface of the torsion sleeve respectively. In the initial state, there is a certain angle between the side of the fixed plate and the vertical central axis of the wire trough box.

[0009] Preferably, a surface of one side of the arc-shaped clamping block close to the center of the torsion sleeve is configured as an arc-shaped surface to better adapt to the outer surface of the cable.

[0010] Preferably, there are multiple groups of arc-shaped pieces, which are evenly distributed on the side of the arc-shaped clamping block near the edge of the arc-shaped surface, so that the multiple groups of arc-shaped pieces can be clamped by the arc-shaped pieces at the bending position caused by the rotation of the torsion sleeve.

[0011] Preferably, a clamping assembly is provided on the top of the torsion sleeve, and the clamping assembly includes a pull rope, the end of the pull rope is fixedly connected to the arc-shaped outer wall of the fixed column, the other end of the pull rope is fixedly connected to an L-shaped slider, the top surface of the L-shaped slider is fixedly connected to a small spring, the inner wall of the torsion sleeve is rotatably installed with a guide roller, the side wall of the L-shaped slider is fixedly connected to an arc-shaped pressure block, and a sliding groove is provided at the center of the arc-shaped block.

[0012] Preferably, a rectangular cavity adapted to the size of the L-shaped slider is opened on the inner wall of the fixed plate, and a rectangular groove with a width adapted to the width of the connection between the L-shaped slider and the arc-shaped pressure block is opened between the sliding groove and the rectangular cavity, so as to ensure that the L-shaped slider can drive the arc-shaped pressure block to slide in the vertical direction along the side wall of the fixed plate.

[0013] Preferably, the elastic coefficient of the small spring is smaller than the elastic coefficient of the coil spring, so that the torsion sleeve will rotate under the influence of the elastic force of the coil spring, thereby driving the pull rope to drag the L-shaped slider downward, which can stretch the small spring to extend it.

[0014] Compared with the prior art, the present invention provides a wire duct device for high and low voltage switch cabinets, which has the following beneficial effects:

[0015] 1. The cable duct device for high and low voltage switchgear is provided with a torsion assembly. Once an accidental touch or pulling occurs, due to the setting of the coil spring and the rotatable connection between the torsion sleeve and the fixed column, the cable is clamped by the deflected arc-shaped clamping block and the arc-shaped sheet, forming several small S-shaped bending areas near the tops of the torsion sleeves. The local bending can offset the pulling force without causing large-scale displacement, thereby ensuring the stability of the cable after wiring and preventing the problem of cable displacement and entanglement due to manual wiring or maintenance.

[0016] 2. The cable duct device for high and low voltage switchgear is provided with a clamping assembly. When the torsion sleeve rotates, the pull rope drags the L-shaped slider downward and drives the arc-shaped clamping block to move downward along the side wall of the fixed plate, thereby compressing the cable in the vertical direction and slightly deforming it. A part of the surface is stuck in the sliding groove, thereby further improving the connection stability between the cable and the arc-shaped clamping block and reducing the possibility of the cable being displaced due to external influences.

DETAILED DESCRIPTION

[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a wire trough device for high and low voltage switch cabinets, including a cabinet body 1, a control panel 2 is fixedly installed on the inner wall of the cabinet body 1, a wire trough box 3 is fixedly installed on the side of the control panel 2, a cover plate 4 is detachably installed on the top inner wall of the wire trough box 3, and a torsion assembly 5 is arranged inside the wire trough box 3. The torsion assembly 5 includes a fixed column 51, a torsion sleeve 52, a coil spring 53, a fixed plate 54, an arc-shaped block 55 and an arc-shaped sheet 56.

[0024] In one embodiment of the present utility model, the bottom end of the fixed column 51 is fixedly mounted on the bottom inner wall of the wire trough box 3, the top surface of the fixed column 51 is rotatably connected to the torsion sleeve 52, a coil spring 53 is sleeved on the top outer wall of the fixed column 51, a fixed plate 54 is fixedly mounted on the upper surface of the torsion sleeve 52, an arc-shaped block 55 is fixedly mounted on the outer wall of the fixed plate 54 close to the torsion sleeve 52, and an arc-shaped piece 56 is fixedly mounted on the side wall of the arc-shaped block 55.

[0025] Furthermore, the number of wire trough boxes 3 is set to multiple groups, and the multiple groups of wire trough boxes 3 are arranged in a frame shape on the outside of the control board 2, so that the wires can be routed inside the wire trough boxes 3 and can correspond to the multiple groups of switches set on the control board 2, so as to achieve neat and beautiful distribution of lines inside the cabinet 1 and facilitate maintenance by the staff. At the same time, the inner wall of the cover plate 4 is provided with multiple groups of through holes to facilitate the cables to extend from the inside of the wire trough box 3 and connect with the switches on the control board 2. Specifically, the number of torsion components 5 is set to multiple groups, and the multiple groups of torsion components 5 are arranged in a linear array on the bottom inner surface of the wire trough box 3.

[0026] At the same time, the torsion sleeve 52 is arranged in a bottle cap shape, and the two ends of the coil spring 53 are fixedly connected to the arc-shaped outer wall of the fixing column 51 and the top inner surface of the torsion sleeve 52 respectively, and in the initial state, there is a certain angle between the side of the fixing plate 54 and the vertical central axis of the cable trough box 3, so that when the cable is laid on the torsion sleeve 52, it is affected by the elastic force of the coil spring 53, and the torsion sleeve 52 always has a rotation tendency, thereby cooperating with the fixing plate 54 to generate a certain torsional force on the cable, so that the cable is bent in an S shape at the edge of the fixing plate 54. Furthermore, the surface of one side of the arc-shaped clamping block 55 near the center of the torsion sleeve 52 is arranged into an arc surface to better adapt to the outer surface of the cable, avoid excessive wear on the cable skin, and affect the safety and insulation of the cable. , there are multiple groups of arc pieces 56, and multiple groups of arc pieces 56 are evenly distributed on the side of the arc-shaped clamping block 55 near the edge of the arc surface, so that multiple groups of arc pieces 56 can be clamped by the arc pieces 56 at the bending position caused by the rotation of the torsion sleeve 52, further ensuring the stability and tensile resistance of the cable after the laying is completed. Since the number of torsion components 5 is arranged in a linear array, the same cable is laid on the torsion component 5 on a straight line, so that several small bending areas are formed outside the cable. Once the cable is subjected to external tension and produces a drag effect, the local bending can offset the tension without causing large-scale displacement, thereby ensuring the stability of the cable after laying and preventing the problem of cable displacement and entanglement due to manual wiring or maintenance.

[0027] In addition, a clamping assembly 6 is provided on the top of the torsion sleeve 52, and the clamping assembly 6 includes a pull rope 61. The end of the pull rope 61 is fixedly connected to the arc-shaped outer wall of the fixed column 51, and the other end of the pull rope 61 is fixedly connected to an L-shaped slider 62. The top surface of the L-shaped slider 62 is fixedly connected to a small spring 63. A guide roller 64 is rotatably installed on the inner wall of the torsion sleeve 52, and the side wall of the L-shaped slider 62 is fixedly connected to an arc-shaped pressure block 65. A sliding groove 66 is provided at the center of the arc-shaped block 55.

[0028] In an embodiment of the present utility model, there are two groups of clamping assemblies 6, and the two groups of clamping assemblies 6 are symmetrically arranged with the vertical central axis of the torsion sleeve 52 as the symmetry axis. At the same time, the pull rope 61 is connected to the guide roller 64 in a transmission manner so that the guide roller 64 can change the force direction of the pull rope 61. In addition, a rectangular cavity that is adapted to the size of the L-shaped slider 62 is opened on the inner wall of the fixed plate 54, and a rectangular groove with a width that is adapted to the width of the connection between the L-shaped slider 62 and the arc-shaped pressure block 65 is opened between the sliding groove 66 and the rectangular cavity to ensure that the L-shaped slider 62 can drive the arc-shaped pressure block 65 to slide vertically along the side wall of the fixed plate 54. Specifically, the elastic coefficient of the small spring 63 is smaller than the elastic coefficient of the coil spring 53, so that the torsion sleeve 52 will rotate under the influence of the elastic force of the coil spring 53, thereby driving the pull rope 61 to drag the L-shaped slider 62 downward to stretch the small spring 63.

[0029] Specifically, the width of the arc-shaped pressure block 65 is adapted to the width of the sliding groove 66, so that the contact surface between the arc-shaped clamping block 55 and the cable is U-shaped, and the setting of the arc-shaped pressure block 65 just fills the gap in the center of the U-shaped arc-shaped clamping block 55. And because the arc-shaped pressure block 65 is at the top, it can compress the cable in the vertical direction and slightly deform it when it moves downward, and a part of the surface is stuck in the sliding groove 66, thereby further improving the connection stability between the cable and the arc-shaped clamping block 55 and reducing the possibility of the cable being displaced by external influences.

[0030] In the present invention, when in use, the cover plate 4 is opened, and the cables are inserted into the corresponding torsion components 5 in a straight line along the inside of the cable trough box 3, leaving enough wire ends to pass through the through holes set on the top of the cover plate 4, and the wire ends are connected to the switches on the control panel 2 to complete the wiring of the cables. During the wiring process, if there is an accidental touch or pulling phenomenon, due to the setting of the coil spring 53 and the rotatable connection between the torsion sleeve 52 and the fixed column 51, the cables are affected by the clamping of the arc-shaped block 55 and the arc-shaped piece 56 in the deflected state, and several small S-shaped bending areas are formed near the tops of the torsion sleeves 52. The local bending can offset the pulling force without causing large-scale displacement, thereby ensuring the stability of the cables after laying and preventing the problem of cable displacement and entanglement due to manual wiring or maintenance.

[0031] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
