Description

Technical Field

[0001] The present application relates to the technical field of power protection, and in particular to a low-voltage insulating protective cover. Background Art

[0002] The distribution meter box is equipped with electric meters, transformers, RTOs, terminal blocks, etc. Among them, transformers, RTOs, terminal blocks, etc. carry 220V-380V voltage and are exposed. When operators read meters, inspect and maintain them, they are close to the above-mentioned live parts, posing a great safety hazard.

[0003] In this regard, China's patent application number CN201610399927.6 discloses a low-voltage insulating protective cover. The solution is mainly composed of an insulating rubber cover, two sliding mounting frames, a handle and a magnet, which is an internal protective cover of a distribution meter box. The transformer, RTO, terminal block and other exposed live parts are completely covered, so that other equipment in the distribution meter box can be insulated and protected when maintenance is performed.

[0004] However, in the process of implementing the technical solution in the embodiments of the present application, the inventor of the present application found that the above technology has at least the following technical problems:

[0005] 1. The sliding mounting frame can slide along the rubber cover body, and the mask area between the two sliding mounting frames can be adjusted, but the rest of the rubber cover body is in an unfolded state, which will interfere with personnel operation.

[0006] 2. The width of the rubber cover is fixed, so the coverage area is limited and the expandability is not strong. Utility Model Content

[0007] In order to make up for the above deficiencies, the present application provides a low-voltage insulating protective cover, aiming to improve the problems mentioned in the above background technology.

[0008] An embodiment of the present application provides a low-voltage insulating protective cover, including a box body, wherein a winding mechanism is provided in the box body, an insulating tape is wound on the winding mechanism, adjacent winding mechanisms are connected by a detachable shaft, a magnetic clip is provided on the lower surface of the box body, and a clip groove matched with the clip is opened on the upper surface of the box body.

[0009] In a specific embodiment, the winding mechanism includes a reel, the reel is rotatably connected to the box body, and the insulating tape is wound on the reel.

[0010] In the above implementation process, the portion of the insulating tape that is pulled out is subjected to insulating shielding, and the portion that is not pulled out is wound on a reel for storage.

[0011] In a specific embodiment, a soft magnetic strip is fixedly connected to the outer end of the insulating tape.

[0012] In the above implementation process, the box body is attracted to the metal side plate on one side of the distribution box by means of a magnetic clip, and the pulled-out insulating tape is attached to the metal side plate on the other side of the distribution box by means of a soft magnetic strip.

[0013] In a specific embodiment, the outer end of the insulating tape is provided with a flange.

[0014] In the above implementation process, the flange is convenient for holding.

[0015] In a specific embodiment, the winding mechanism further includes a spring, and two ends of the spring are fixedly connected to the reel and the box body respectively.

[0016] In the above implementation process, the mainspring is used to help the reel to reset, thereby reeling up the insulating tape.

[0017] In a specific implementation manner, both ends of the reel are respectively provided with plug-in grooves, and teeth are provided in the plug-in grooves.

[0018] In the above implementation process, when multiple box bodies are connected in series, the teeth are used to maintain mutual engagement, and multiple winding mechanism shafts are connected through the plug-in slots, so that all the winding mechanisms connected in series will rotate synchronously, which is easy to operate.

[0019] In a specific implementation manner, a card block is inserted into the insertion slot, and the card block is pin-connected to the box body.

[0020] In the above implementation process, the card block is inserted into the box body and the plug-in slot at the same time to lock the reel, and then lock all the winding mechanisms in series to prevent the spring from retracting the insulating tape. One card block can lock all the winding mechanisms in series, simplifying the operation.

[0021] In a specific embodiment, the cross-sections of the clamping strip and the clamping slot are both in an inverted T-shape.

[0022] In the above implementation process, the upper box body is simultaneously plugged into the two adjacent box bodies below, and the two box bodies are connected together by utilizing the connection effect of the card strip and the card slot. On the other hand, when a large gap appears between the two adjacent insulating tapes below, the upper insulating tape can also be pulled out to cover the gap, thereby further improving safety.

[0023] Compared with the prior art, the beneficial effects of the present application are: the box body can be connected in series by inserting the card strip into the card slot, thereby achieving a wider coverage and improving the expandability; the unpulled insulating tape is rolled up by the winding mechanism and will not interfere with the operation of personnel.

[0029] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0030] See also Figure 1-Figure 3 The present application provides a low-voltage insulating protective cover, including a box body 10, a reeling mechanism 20 is provided inside the box body 10, an insulating tape 30 is reeled on the reeling mechanism 20, adjacent reeling mechanisms 20 are detachably connected by shafts, a magnetic clamping strip 40 is provided on the lower surface of the box body 10, and a clamping slot 50 adapted to the clamping strip 40 is provided on the upper surface of the box body 10. The box body 10 can be connected in series by inserting the clamping strip 40 into the clamping slot 50, thereby achieving a wider coverage and improving the expandability, and the unpulled insulating tape 30 is reeled in by the reeling mechanism 20, which will not interfere with the operation of personnel.

[0031] See also Figure 1-Figure 3 The winding mechanism 20 includes a reel 21, which is rotatably connected to the box body 10, and the insulating tape 30 is wound on the reel 21. The pulled-out portion of the insulating tape 30 is insulated and shielded, and the unpulled portion is wound on the reel 21 for storage.

[0032] See also Figure 1-Figure 3 The outer end of the insulating tape 30 is fixedly connected with a soft magnetic strip 60. The box body 10 is sucked on the metal side plate on one side of the distribution box by the magnetic clamping strip 40, and the pulled insulating tape 30 is attached to the metal side plate on the other side of the distribution box by the soft magnetic strip 60. The soft magnetic strip 60 is also used to clamp on the edge of the box body 10 to avoid being rolled in.

[0033] See also Figure 1-Figure 3 The outer end of the insulating tape 30 is provided with a flange 70. The flange 70 is convenient for hand holding.

[0034] See also Figure 1-Figure 3 The winding mechanism 20 further includes a spring 22, and both ends of the spring 22 are respectively fixedly connected to the reel 21 and the box body 10. The spring 22 is used to help the reel 21 to reset, so as to rewind the insulating tape 30.

[0035] See also Figure 1-Figure 3 , plug-in slots 23 are respectively provided at both ends of the reel 21, and teeth are provided in the plug-in slots 23. When multiple boxes 10 are connected in series, the teeth are used to keep each other engaged, and multiple winding mechanisms 20 are connected through the plug-in slots 23, so that all the winding mechanisms 20 connected in series will rotate synchronously, which is convenient for operation.

[0036] See also Figure 1-Figure 3 A block 24 is inserted into the insertion slot 23, and the block 24 is pinned to the box body 10. The block 24 is inserted into the box body 10 and the insertion slot 23 at the same time to lock the reel 21, and then all the winding mechanisms 20 connected in series are locked to prevent the spring 22 from retracting the insulating tape 30. One block 24 can lock all the winding mechanisms 20 connected in series, simplifying the operation.

[0037] See also Figure 1-Figure 3 The cross sections of the clamping strip 40 and the clamping slot 50 are both inverted T-shaped. The upper box body 10 is plugged into the two adjacent box bodies 10 at the same time, and the two box bodies 10 are connected together by using the connection effect of the clamping strip 40 and the clamping slot 50. On the other hand, when a large gap appears between the two adjacent insulating tapes 30 at the bottom, the upper insulating tape 30 can also be pulled out to cover the gap, further improving safety.

[0038] The working principle of the low-voltage insulating protective cover is as follows: according to the width to be covered, multiple box bodies 10 are connected in series, and the upper box body 10 is simultaneously plugged into the two adjacent box bodies 10 below. The two box bodies 10 are connected together by using the connection effect of the card strip 40 and the card slot 50, and all the insulating tapes 30 connected in series are pulled out, and the soft magnetic strip 60 is used to fit the metal side plate on the other side of the distribution box, thereby forming an insulating shielding effect. When the insulating tape 30 is pulled out, the clockwork 22 starts to accumulate power. In order to prevent the insulating tape 30 from being pulled back, the card block 24 is simultaneously plugged in. The reel 21 is locked on the box body 10 and the plug-in slot 23 at one end, and then all the winding mechanisms 20 connected in series are locked to prevent the spring 22 from retracting the insulating tape 30. When a large gap appears between the two adjacent insulating tapes 30 below, the upper insulating tape 30 can also be pulled out to cover the gap, further improving safety. In summary, the box body 10 can be inserted into the card slot 50 through the card strip 40 to achieve a series combination, achieve a wider coverage, and improve expandability. The insulating tape 30 that is not pulled out is retracted by the winding mechanism 20 and will not interfere with personnel operation.
