Description

Technical Field

[0001] This utility model relates to the field of outgoing line sealing technology, and in particular to an inlet and outlet line sealing structure for a power distribution cabinet. Background Technology

[0002] A distribution cabinet is a critical electrical device in a power system. It consists of a cabinet, busbars, various switches, measuring instruments, and protective devices. The cabinet is made of cold-rolled steel plate with surface treatment, making it sturdy, durable, and effectively protecting the internal components.

[0003] When connecting electrical wires to the outside of the distribution cabinet, the connection points need to be sealed with appropriate inlet and outlet sealing structures. By tightly sealing the gaps between the inlet and outlet wires, the intrusion of external interference factors such as dust, moisture and small animals can be effectively blocked, preventing short circuits caused by dust accumulation affecting heat dissipation and moisture, as well as problems such as small animals chewing on the cables.

[0004] Traditionally, distribution cabinets are filled and sealed using insulating rubber blocks or sponge pads. This method of fixing makes the filler material easily moved by the wires, resulting in poor sealing of the cabinet. To solve this problem, existing technology uses special insulating rubber tubes in conjunction with filler blocks for sealing. Although this sealing method avoids the problem of loosening, it can only pass through a fixed number of wires and cannot be adjusted according to the actual number of cables, thus reducing the practicality of the device. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a sealing structure for the incoming and outgoing lines of a power distribution cabinet, which aims to improve the problem that the existing technology can only pass through a fixed number of wires and cannot be adjusted according to the actual number of cables, thereby reducing the practicality of the device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sealing structure for the inlet and outlet lines of a power distribution cabinet, comprising an outlet pipe, with fixed housings fixedly connected to the upper and lower ends of the outlet pipe, clips slidably connected at equal intervals on adjacent inner sides of the two fixed housings, guide blocks fixedly connected to the upper and lower sides of multiple clips, turntables rotatably connected to the inner sides of the two fixed housings, guide grooves provided on the top walls of the two turntables, connecting rods fixedly connected at equal intervals on the outer walls of the two turntables, adjusting rings fixedly connected to the ends of multiple connecting rods, and a quick-installation and disassembly mechanism installed on the outer side of the outlet pipe, the quick-installation and disassembly mechanism being used for quick installation of the sealing structure for the inlet and outlet lines of the power distribution cabinet.

[0007] As a further description of the above technical solution:

[0008] The quick assembly / disassembly mechanism includes a thickened tube, the inner wall of which is fixedly connected to the outer wall of the outlet tube. Multiple fixing buckles are equidistantly slidably connected to the upper and lower ends of the outer wall of the thickened tube. A spring is fixedly connected to one adjacent end of each of the multiple fixing buckles. A steel wire is fixedly connected to the middle of one adjacent side of each of the multiple fixing buckles. A rotating ring is fixedly connected to the end of each of the multiple steel wires. Anti-slip textures are provided on the outer walls of the two rotating rings.

[0009] As a further description of the above technical solution:

[0010] Each of the multiple clips has a protective pad installed on an adjacent side, and each of the multiple protective pads has a tack fixedly connected to its upper and lower ends.

[0011] As a further description of the above technical solution:

[0012] Both of the adjusting rings have rubber rings fixedly connected to their outer walls, and both rubber rings have multiple grooves equidistantly spaced on their outer walls.

[0013] As a further description of the above technical solution:

[0014] Multiple rotating rods are fixedly connected at equal intervals to the upper and lower ends of the inner side of the thickened tube, and pulleys are rotatably connected to the outer walls of the multiple rotating rods.

[0015] As a further description of the above technical solution:

[0016] The inner wall of the outlet pipe is provided with multiple grooves at equal intervals, and the inner side of each groove is fixedly connected with a sponge.

[0017] As a further description of the above technical solution:

[0018] A sealing ring is installed in the middle of the outer wall of the thickened tube, and multiple thumbtacks are fixedly connected at equal intervals to the upper and lower ends of the outer wall of the sealing ring.

[0019] As a further description of the above technical solution:

[0020] Information panels are installed on the front of both of the fixed shells, and screws are threaded onto the left and right sides of both information panels.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the rotating adjustment ring drives the turntable to rotate inside the fixed shell through the connecting rod. While the turntable rotates, it will drive the corresponding clip to slide inside the fixed shell through the guide groove and guide block, thereby clamping and fixing the wires connected to the distribution cabinet. This achieves the effect of clamping and fixing different numbers of cables, while the cables will not easily pull the filler and affect its sealing performance.

[0023] 2. In this utility model, the rotating ring pulls the corresponding fixing buckle back into the thickened tube by the steel wire, and then the quick-installation mechanism is pulled out for replacement. After the new quick-installation mechanism is inserted into the distribution cabinet, the rotating ring is released so that the spring pushes the corresponding fixing buckle to pop out, thereby fixing it, thus achieving the effect of quick installation and removal of the sealing structure of the distribution cabinet's inlet and outlet lines.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0032] Reference Figure 2 and Figure 3This utility model provides an embodiment of a distribution cabinet inlet and outlet sealing structure, including an outlet pipe 1. The upper and lower ends of the outlet pipe 1 are fixedly connected to fixed housings 3. Clamps 4 are equidistantly slidably connected to adjacent inner sides of the two fixed housings 3. The fixed housings 3 are used to install the clamps 4. Guide blocks 5 are fixedly connected to the upper and lower sides of the clamps 4. Turntables 6 are rotatably connected to the inner sides of the two fixed housings 3. Guide grooves 7 are provided on the top walls of the two turntables 6. The turntables 6 drive the clamps 4 to slide through the guide grooves 7 and guide blocks 5. Connecting rods 8 are equidistantly fixed to the outer walls of the two turntables 6. An adjusting ring 9 is fixedly connected to the end of each connecting rod 8. The adjusting ring 9 drives the turntable 6 to rotate through the connecting rod 8. A quick-installation mechanism 2 is installed on the outside of the outlet pipe 1. The quick-installation mechanism 2 is used to quickly install the sealing structure of the power distribution cabinet's inlet and outlet lines. Protective pads 10 are installed on the adjacent sides of multiple clips 4. Thumbtacks 11 are fixedly connected to the upper and lower ends of multiple protective pads 10. Thumbtacks 11 are used to fix the protective pads 10. Rubber rings 12 are fixedly connected to the outer walls of the two adjusting rings 9. Multiple grooves 13 are equally spaced on the outer walls of the two rubber rings 12. The grooves 13 are used to increase the friction of the rubber rings 12.

[0033] Specifically, rotating the two adjusting rings 9 on both sides of the sealing structure of the power distribution cabinet's inlet and outlet lines causes the adjusting rings 9 to rotate the turntable 6 within the fixed housing 3 via the connecting rod 8. As the turntable 6 rotates, the corresponding guide groove 7 on it, in conjunction with the corresponding guide block 5, causes the corresponding clip 4 to slide inside the fixed housing 3, thereby clamping and fixing the wires connected to the power distribution cabinet. The protective pad 10, which is fixed by the thumbtack 11, provides protection for the wires. The rubber ring 12, which is fixed outside the adjusting ring 9, has its anti-slip properties enhanced by the groove 13 on its outside.

[0034] Reference Figure 4 and Figure 5 The quick assembly / disassembly mechanism 2 includes a thickened tube 201. The inner wall of the thickened tube 201 is fixedly connected to the outer wall of the outlet tube 1. Multiple fixing buckles 202 are equidistantly slidably connected to the upper and lower ends of the outer wall of the thickened tube 201. The fixing buckles 202 slide inside the thickened tube 201. A spring 203 is fixedly connected to one adjacent end of each of the multiple fixing buckles 202. The spring 203 is used to push the fixing buckle 202. A steel wire 204 is fixedly connected to the middle of one adjacent side of each of the multiple fixing buckles 202. A rotating ring 205 is fixedly connected to the end of each of the multiple steel wires 204. The rotating ring 205 pulls the fixing buckle 202 through the steel wire 204. Anti-slip textures 206 are provided on the outer walls of the two rotating rings 205. Multiple rotating rods 14 are equidistantly fixedly connected to the upper and lower ends of the inner side of the thickened tube 201. A pulley 15 is rotatably connected to the outer wall of each of the multiple rotating rods 14. The rotating rods 14 are used to fix the pulleys 15.

[0035] Specifically, rotating the rotating rings 205 installed on both sides of the thickened tube 201 pulls the corresponding steel wires 204. At this time, the anti-slip textures 206 on the outside of the rotating rings 205 can increase its friction. Then, the corresponding fixing buckles 202 are pulled by multiple steel wires 204, thereby driving multiple fixing buckles 202 to retract into the thickened tube 201. Then, the quick-release mechanism 2 is pulled out for replacement. After inserting the new quick-release mechanism 2 into the distribution cabinet, the rotating rings 205 are released, so that the spring 203 pushes the corresponding fixing buckles 202 to pop out, thereby fixing them. The pulley 15 fixed by the rotating rod 14 can improve the smoothness of the steel wires 204.

[0036] Reference Figure 1 and Figure 4 The inner wall of the outlet pipe 1 is provided with multiple grooves 16 at equal intervals. Sponge 17 is fixedly connected to the inner side of each groove 16. The grooves 16 are used to fix the sponge 17. A sealing ring 18 is installed in the middle of the outer wall of the thickened pipe 201. Multiple thumbtacks 19 are fixedly connected to the upper and lower ends of the outer wall of the sealing ring 18 at equal intervals. The thumbtacks 19 are used to fix the sealing ring 18. Information plates 20 are installed on the front side of each of the two fixed shells 3. Screws 21 are threadedly connected to the left and right sides of each of the two information plates 20. The screws 21 are used to fix the information plates 20.

[0037] Specifically, the sponge 17, which is fixed by the groove 16 on the inner wall of the outlet pipe 1, can wrap the wire and prevent it from shaking. The sealing ring 18, which is fixed by the second thumbtack 19, can improve the sealing performance of the inlet and outlet sealing structure of the distribution cabinet. The information board 20, which is fixed by the screw 21, is used to display detailed information about the inlet and outlet sealing structure of the distribution cabinet.

[0038] Working principle: When using the distribution cabinet's inlet and outlet sealing structure to connect the distribution cabinet, first rotate the two adjusting rings 9 on both sides of the distribution cabinet's inlet and outlet sealing structure. When the adjusting rings 9 rotate, they drive the turntable 6 to rotate inside the fixed shell 3 through the connecting rod 8. At the same time as the turntable 6 rotates, it will drive the corresponding clip 4 to slide inside the fixed shell 3 through the guide groove 7 opened on it and the corresponding guide block 5, thereby clamping and fixing the wires connected to the distribution cabinet. This achieves the effect of clamping and fixing different numbers of cables, and at the same time, the cables will not easily pull the filler and affect its sealing performance.

[0039] When replacing the sealing structure of the power distribution cabinet's inlet and outlet lines, first rotate the rotating rings 205 installed on both sides of the thickened tube 201. The rotation of the rotating rings 205 pulls the corresponding steel wires 204. At this time, the anti-slip textures 206 on the outside of the rotating rings 205 can increase its friction. Then, the steel wires 204 pull the corresponding fixing buckles 202, thereby causing the fixing buckles 202 to retract into the thickened tube 201. Then, the quick-release mechanism 2 is pulled out for replacement. After inserting the new quick-release mechanism 2 into the power distribution cabinet, the rotating rings 205 are released, causing the spring 203 to push the corresponding fixing buckles 202 out, thus fixing them. This achieves the effect of quick installation and removal of the sealing structure of the power distribution cabinet's inlet and outlet lines.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
