Description

Technical Field

[0001] The invention relates to the technical field of production related to electric power grids, and in particular to an indoor wiring device for electric power grids. Background Art

[0002] At present, when laying indoor power grids, in order to ensure the beauty of the overall line and improve the efficiency of line maintenance, wiring devices are usually installed indoors to fix the lines. The existing wiring devices still use a more traditional trough and cover structure, that is, the lines are stored through the trough, and then the lines are fixed with the cover. However, in this trough and cover structure, the trough is mainly fixed, which results in that when the line diameter is smaller than the inner diameter of the trough, the line inside the trough will still be loose, which obviously limits the positioning effect of the device on the line. For this reason, we propose an indoor wiring device for power grids. Summary of the invention

[0003] In order to solve the above problems, the present invention provides an indoor wiring device for a power grid.

[0004] The present invention adopts the following technical scheme: an indoor wiring device for an electric power grid, comprising a wiring disk, a plurality of wiring grooves arranged parallel to each other are provided on both sides of the upper end surface of the wiring disk, a cover plate matching its diameter is rotatably installed on the upper end surface of the wiring disk, a positioning cavity is respectively provided in the middle of each of the wiring grooves, two symmetrically arranged clamping plates are slidably installed in the positioning cavity, a rotating plate slidably matched with the lower ends of the clamping plates on both sides is rotatably installed on the lower side of the inner cavity of the positioning cavity, a movable plate slidably matched with the periphery of the rotating plate is plugged and installed on one side of the upper end of the positioning cavity, and the upper end of each of the movable plates matches the position of the cover plate.

[0005] As a further description of the above technical solution: a limited rotation cavity is opened on the lower side of the positioning cavity, the rotating plate is rotatably installed in the limited rotation cavity, and limited sliding grooves are opened on the upper and lower sides of the limited rotation cavity, and the lower ends of the clamping plates on both sides are respectively provided with limiting sliding blocks that slide in cooperation with the upper and lower limiting sliding grooves.

[0006] As a further description of the above technical solution: arc-shaped sliding grooves symmetrically distributed along the center are opened on both sides of the upper end of the rotating plate, and a sliding shaft that slides in cooperation with the arc-shaped sliding grooves is fixedly installed between the upper and lower limit sliders.

[0007] As a further description of the above technical solution: the upper end surface of the wiring disk is provided with a plurality of insertion cavities respectively arranged on the inner side of each positioning cavity, the insertion cavities are interconnected with the inner cavity of the positioning cavity, and the movable plate is plugged and installed in the insertion cavities.

[0008] As a further description of the above technical solution: a threaded groove is opened on the periphery of the rotating plate, a convex shaft slidingly matched with the threaded groove is fixedly installed on the outer end of the movable plate, and a first spring is fixedly installed between the movable plate and the insertion cavity.

[0009] As a further description of the above technical solution: the upper end surfaces of the limit sliders on both sides are respectively fixedly installed with fixed seats, and the second spring and the telescopic sleeves that are inserted into each other are fixedly installed between the clamping plates on both sides and the fixed seats, and the second spring is arranged in the telescopic sleeve.

[0010] As a further description of the above technical solution: a limited rotation hole is provided on the upper end surface of the wiring disk, and a limited rotation shaft which is rotatably matched with the limited rotation hole is fixedly installed on the lower end surface of the cover plate.

[0011] As a further description of the above technical solution: a positioning tooth hole is provided on the lower end surface of the limiting rotation shaft, a positioning tooth groove is provided on the bottom end surface of the inner cavity of the limiting rotation hole, a positioning gear rod which is plugged into the positioning tooth groove is installed in the positioning gear hole, and the contact surface between the positioning tooth groove and the positioning gear rod is inclined, and a third spring is fixedly installed between the positioning gear rod and the positioning gear hole.

[0012] The present invention provides an indoor wiring device for a power grid through improvement, which has the following improvements and advantages compared with the prior art: First, through the sliding cooperation between the movable plate and the rotating plate and between the rotating plate and the clamping plates on both sides, when the rotating cover plate contacts the movable plate, it can drive the clamping plates on both sides to move toward each other, so as to achieve the effect of clamping and positioning the line in the positioning cavity, and prevent the line from loosening in the wiring groove.

[0013] Second, through the sliding cooperation between the limit slider and the limit slide groove and between the arc slide groove and the slide shaft, the rotating rotating plate can drive the clamping plates on both sides to move toward and away from each other.

It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0020] See also Figure 1 - Figure 6 The embodiment of the present invention provides a technical solution: an indoor wiring device for an electric power grid, comprising a wiring disk 1, wherein a plurality of wiring grooves 11 arranged in parallel to each other are provided on both sides of the upper end surface of the wiring disk 1, a cover plate 12 matching its diameter is rotatably installed on the upper end surface of the wiring disk 1, a positioning cavity 2 is respectively provided in the middle of each wiring groove 11, two symmetrically arranged clamping plates 21 are slidably installed in the positioning cavity 2, a rotating plate 22 slidably matched with the lower ends of the clamping plates 21 on both sides is rotatably installed on the lower side of the inner cavity of the positioning cavity 2, a movable plate 25 slidably matched with the outer periphery of the rotating plate 22 is plugged and installed on one side of the upper end of the positioning cavity 2, and the upper end of each movable plate 25 matches the position of the cover plate 12.

[0021] Specifically, through the sliding cooperation between the movable plate 25 and the rotating plate 22 and between the rotating plate 22 and the clamping plates 21 on both sides of its upper end, when the rotating cover plate 12 covers the upper end of the wiring groove 11, the contact effect between the cover plate 12 and the movable plate 25 can drive the clamping plates 21 on both sides to move toward each other in the positioning cavity 2, thereby achieving the effect of clamping and positioning the line in the wiring groove 11.

[0022] In another embodiment provided by the present invention, a limited rotation cavity 221 is provided at the lower side of the positioning cavity 2, and the rotating plate 22 is rotatably installed in the limited rotation cavity 221. Limited sliding grooves 231 are provided on the upper and lower sides of the limited rotation cavity 221. The lower ends of the clamping plates 21 on both sides are respectively provided with limiting sliders 23 that slidably cooperate with the upper and lower limiting sliding grooves 231. The upper ends of the rotating plates 22 are provided with arc-shaped sliding grooves 241 that are symmetrically distributed with the center. A sliding shaft 24 that slidably cooperates with the arc sliding grooves 241 is fixedly installed between the upper and lower limiting sliders 23. A plurality of insertion cavities 252 are provided on the upper end surface of the wiring disk 1, which are respectively provided on the inner sides of each positioning cavity 2. The insertion cavities 252 are communicated with the inner cavity of the positioning cavity 2, and the movable plate 25 is plugged and installed in the insertion cavity 252. A threaded sliding groove 261 is provided on the outer periphery of the rotating plate 22. A convex shaft 26 that slidably cooperates with the threaded sliding groove 261 is fixedly installed on the outer end of the movable plate 25, and a first spring 251 is fixedly installed between the movable plate 25 and the insertion cavity 252.

[0023] Specifically, through the sliding cooperation between the convex shaft 26 and the threaded groove 261, the movable plate 25 moving up and down can drive the rotating plate 22 to rotate forward or reverse in the limited rotation cavity 221; Through the sliding cooperation between the limiting slider 23 and the limiting slide groove 231 and between the slide shaft 24 and the arc-shaped slide groove 241 , the rotating rotating plate 22 can drive the clamping plates 21 on both sides of its upper end to move toward or away from each other.

[0024] In another embodiment provided by the present invention, fixed seats 27 are fixedly installed on the upper end surfaces of the limiting sliders 23 on both sides, and second springs 271 and telescopic sleeves 272 that are inserted into each other are fixedly installed between the clamping plates 21 on both sides and the fixed seats 27, and the second spring 271 is arranged in the telescopic sleeve 272.

[0025] Specifically, a fixed seat 27 is provided, and a second spring 271 is provided between the fixed seat 27 and the clamping plate 21. When the inner side of the clamping plate 21 contacts the outer periphery of the circuit, the rotating rotating plate 22 can still drive the fixed seat 27 to move, thereby expanding the movable space of the fixed seat 27, the rotating plate 22 and the movable plate 25, and avoiding interference between the movable plate 25 and the cover plate 12.

[0026] In another embodiment provided by the present invention, a limited rotation hole 3 is provided on the upper end surface of the wiring disk 1, a limited rotation shaft 31 that rotates with the limited rotation hole 3 is fixedly installed on the lower end surface of the cover plate 12, a positioning tooth hole 33 is provided on the lower end surface of the limited rotation shaft 31, and a positioning tooth groove 32 is provided on the bottom end surface of the inner cavity of the limited rotation hole 3, a positioning tooth rod 34 that is plugged into the positioning tooth groove 32 is installed in the positioning tooth hole 33, and the contact surface between the positioning tooth groove 32 and the positioning tooth rod 34 is inclined, and a third spring 35 is fixedly installed between the positioning tooth rod 34 and the positioning tooth hole 33.

[0027] Specifically, through the plug-in connection effect between the positioning gear rod 34 and the positioning gear hole 33, in conjunction with the third spring 35, when the cover plate 12 is rotated, since the contact surface between the positioning tooth groove 32 and the positioning gear rod 34 is inclined, the positioning gear rod 34 will be continuously plugged into the positioning tooth groove 32, thereby achieving the effect of positioning the cover plate 12 at the upper end of the wiring tray 1.

[0028] Working principle: When positioning the line, install the line into each wiring groove 11 respectively, and then rotate the cover plate 12 on the upper end of the wiring plate 1 to cover the upper end of each wiring groove 11; During the rotation of the cover plate 12, it will come into contact with the movable plate 25, causing the movable plate 25 to move downward. At this time, the sliding cooperation between the convex shaft 26 and the threaded groove 261 can drive the rotating plate 22 to rotate. The limiting groove 231, through the sliding cooperation between it and the limiting slider 23, limits the movement direction of the fixed seat 27, so that the rotating rotating plate 22 can drive the fixed seats 27 on both sides to move toward each other through the sliding cooperation between the arc groove 241 and the sliding shaft 24, so that the clamping plates 21 on both sides contact the periphery of the line, so as to achieve the effect of positioning the line in the wiring groove 11; Since a second spring 271 is provided between the clamping plate 21 and the fixing seat 27, when the clamping plate 21 contacts the circuit, it will not interfere with the movement of the fixing seat 27, so that the movable plate 25 can move completely into the insertion cavity 252, and the cover plate 12 can completely cover the upper end of the movable plate 25; On the contrary, if the cover plate 12 is rotated in the reverse direction, the cover plate 12 will be separated from the movable plate 25. At this time, the first spring 251 can restore the deformation and drive the movable plate 25 to reset upward. The convex shaft 26 and the threaded groove 261 can slide and cooperate to drive the rotating plate 22 to rotate in the reverse direction, thereby driving the clamping plates 21 on both sides to move backward, so that the clamping plates 21 are separated from the circuit, and the clamping and positioning effect on the circuit is released, so that the circuit can be taken out and reinstalled in the wiring groove 11. Among them, when the rotating plate 22 is rotated, through the plug-in effect between the positioning tooth hole 33 and the positioning gear rod 34, and in conjunction with the third spring 35, the contact surface between the positioning tooth groove 32 and the positioning gear rod 34 is inclined, so that the positioning gear rod 34 rotating with the rotating plate 22 can continuously come into contact with the positioning tooth groove 32, and after each reinsertion, the cover plate 12 can be positioned at the upper end of the wiring disk 1.
