Description

Technical Field

[0001] This application relates to the field of insulating covers, and more particularly to a dustproof insulating cover. Background Technology

[0002] An insulating cover is a protective device used to isolate live conductors and prevent electric shock to personnel or short circuits in equipment. It is usually made of insulating materials and is widely used in power, electronics, industrial equipment and other fields. Before use, it must be checked for integrity and pass the power frequency voltage test. During installation, an insulating rod must be used to operate and ensure that it is firmly fixed. It is suitable for the protection of disconnecting switches with the risk of backfeeding.

[0003] Most current insulating covers are installed by connecting two movable covers that work together to provide insulation. However, when using spliced ​​insulating covers, there will be gaps at the joints. Over time, small dust particles can enter the interior of the cover through these gaps, damaging the internal equipment and affecting its lifespan. Utility Model Content

[0004] To address the issue that gaps exist at the joints of spliced ​​insulating covers during use, allowing small amounts of dust to enter the interior of the cover over extended periods, this application provides a dustproof insulating cover.

[0005] The dustproof insulating cover provided in this application adopts the following technical solution:

[0006] The device includes a mounting base on which a first dust cover and a second dust cover are movably mounted. A first guide strip is installed on the lower side of the first dust cover, and a second guide strip is installed on the lower side of the second dust cover. A sealing movable frame is movably connected to the first dust cover via the first guide strip.

[0007] By adopting the above technical solution, the sealed movable frame is located at the connection between the first dust cover and the second dust cover, protecting the connection and preventing dust from entering the interior of the dust cover through the connection.

[0008] Preferably, a groove is provided on the lower inner side of the sealing movable frame, and the width of the first guide bar and the second guide bar are adapted to the width of the groove, so that the sealing movable frame can move on the first guide bar and the second guide bar.

[0009] By adopting the above technical solution, the sealing moving frame is pushed to move along the first guide strip. Through the continuous movement of the sealing moving frame, one side is connected to the second guide strip. At this time, the sealing moving frame is located at the connection between the first dust cover and the second dust cover, thus protecting the connection.

[0010] Preferably, the lower part of both ends of the sealing movable frame is provided with through holes, and a movable push plate is installed on the outer side of the sealing movable frame outside the through holes, and limit rods are installed at both ends of the movable push plate.

[0011] By adopting the above technical solution, rotating the screw can drive the moving push plate to move continuously. When the moving push plate moves, it can drive the limit rods at both ends to move. One end of the limit rod gradually extends out from the inside of the through hole, which can fix the sealing moving frame and prevent the sealing moving frame from moving.

[0012] Preferably, the lower part of the first dust cover and the second dust cover is provided with a positioning hole, the diameter of the limiting rod is adapted to the diameter of the positioning hole and the through hole, and one end of the limiting rod passes through the inside of the through hole and connects to the inside of the positioning hole.

[0013] By adopting the above technical solution, one end of the limiting rod gradually extends out from the inside of the through hole. Through the continuous movement of the limiting rod, one end of the limiting rod can enter the positioning hole opened on the first dust cover and the second dust cover, at which point the sealing moving frame can be fixed.

[0014] Preferably, a screw is installed in the middle of the movable push plate, the screw passes through the middle of the movable push plate and is threadedly connected to the movable push plate, and one end of the screw is rotatably connected to the sealing movable frame.

[0015] By adopting the above technical solution, rotating the screw can drive the moving push plate to move continuously, and the movement of the moving push plate can drive the limit rods at both ends to move.

[0016] Preferably, side baffles are installed on both sides of the mounting base, and a protective strip is installed on the lower outer side of the side baffles. The outer side of the side baffles is in contact with the lower part of the first dust cover and the second dust cover.

[0017] By adopting the above technical solution, the side baffles that fit against the lower part of the first and second dust covers can prevent dust from entering from the bottom.

[0018] Preferably, a fixed base is installed on the inner side of the first dust cover and the second dust cover, and a movable wheel is installed on the fixed base. The lower part of the movable wheel is located on the protective strip, and an observation window is provided on both the first dust cover and the second dust cover.

[0019] By adopting the above technical solution, the first dust cover and the second dust cover are pushed inward. At this time, the moving wheels on the inner side of the first dust cover and the second dust cover will move on the protective strip, ensuring that the first dust cover and the second dust cover move smoothly and reducing noise.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. This application uses the opposite ends of the first dust cover and the second dust cover to contact each other, push the sealing moving frame, and make the sealing moving frame move along the first guide strip. Through the continuous movement of the sealing moving frame, one side connects with the second guide strip. At this time, the sealing moving frame is located at the connection between the first dust cover and the second dust cover, protecting the connection and preventing dust from entering the dust cover through the connection.

[0022] 2. This application can drive the movable push plate to move continuously by rotating the screw. When the movable push plate moves, it can drive the limit rods at both ends to move. One end of the limit rod gradually extends out of the through hole. Through the continuous movement of the limit rod, one end of the limit rod can enter the positioning hole opened on the first dust cover and the second dust cover. At this time, the sealing movable frame can be fixed to prevent the sealing movable frame from moving and improve its stability. Attached Figure Description

A sealing movable frame 8 is movably connected to the first dustproof cover 4 through the first guide strip 6. A sliding groove 9 is opened on the lower inner side of the sealing movable frame 8. The width of the first guide strip 6 and the second guide strip 7 are adapted to the width of the sliding groove 9. The sealing movable frame 8 can move on the first guide strip 6 and the second guide strip 7. Pushing the sealing movable frame 8 causes it to move along the first guide strip 6. Through the continuous movement of the sealing movable frame 8, one side connects with the second guide strip 7. At this time, the sealing movable frame 8 is located at the connection between the first dustproof cover 4 and the second dustproof cover 5, protecting the connection and preventing dust from entering the interior of the dustproof cover through the connection.

[0031] Please refer to Figure 2 and Figure 4 The sealing movable frame 8 has through holes 10 at its lower ends. A movable push plate 11 is installed on the outer side of the sealing movable frame 8, outside the through holes 10. Limiting rods 12 are installed at both ends of the movable push plate 11. Positioning holes 14 are provided at the lower parts of the first dust cover 4 and the second dust cover 5. The diameter of the limiting rod 12 matches the diameter of the positioning hole 14 and the through hole 10. One end of the limiting rod 12 passes through the interior of the through hole 10 and connects to the interior of the positioning hole 14. A screw 13 is installed in the middle of the movable push plate 11, and the screw 13 passes through the movable push plate 11. The screw 13 is threadedly connected to the movable push plate 11 in the middle. One end of the screw 13 is rotatably connected to the sealing movable frame 8. When the screw 13 is rotated, it can drive the movable push plate 11 to move continuously. When the movable push plate 11 moves, it can drive the limit rods 12 at both ends to move. One end of the limit rod 12 gradually extends out from the inside of the through hole 10. Through the continuous movement of the limit rod 12, one end of the limit rod 12 can enter the positioning hole 14 opened on the first dust cover 4 and the second dust cover 5. At this time, the sealing movable frame 8 can be fixed.

[0032] Please refer to Figure 1 , Figure 3 and Figure 5Side baffles 2 are installed on both sides of the mounting base 1. A protective strip 3 is installed on the lower outer side of the side baffles 2. The outer side of the side baffles 2 fits against the lower part of the first dust cover 4 and the second dust cover 5.

The lower part of the movable wheel 17 is located on the protective strip 3. By pushing the first dust cover 4 and the second dust cover 5 to move inward, the movable wheel 17 on the inner side of the first dust cover 4 and the second dust cover 5 will move on the protective strip 3, ensuring that the first dust cover 4 and the second dust cover 5 move smoothly and reduce noise. An observation window 15 is provided on both the first dust cover 4 and the second dust cover 5, through which the use of the internal device can be easily observed.

[0033] The implementation principle of a dustproof insulating cover according to an embodiment of this application is as follows: When installing internal equipment, the mounting base 1 is first installed on the outside of the equipment. Then, the first dustproof cover 4 and the second dustproof cover 5 are moved to both sides, allowing the internal equipment to be installed. After installation, the first dustproof cover 4 and the second dustproof cover 5 are pushed inward. At this time, the moving wheels 17 on the inner side of the first dustproof cover 4 and the second dustproof cover 5 will move on the protective strip 3, ensuring smooth movement of the first dustproof cover 4 and the second dustproof cover 5 and reducing noise. After the opposite ends of the first dustproof cover 4 and the second dustproof cover 5 come into contact with each other, the sealing moving frame 8 is pushed, causing the sealing moving frame 8 to move along the first guide strip 6. Through the continuous movement of the sealing moving frame 8... One side is connected to the second guide strip 7. At this time, the sealing moving frame 8 is located at the connection between the first dust cover 4 and the second dust cover 5, protecting the connection and preventing dust from entering the dust cover through the connection. Then, the screw 13 is rotated. When the screw 13 rotates, it can drive the moving push plate 11 to move continuously. When the moving push plate 11 moves, it can drive the limit rods 12 at both ends to move. One end of the limit rod 12 gradually extends out from the inside of the through hole 10. Through the continuous movement of the limit rod 12, one end of the limit rod 12 can enter the positioning hole 14 opened on the first dust cover 4 and the second dust cover 5. At this time, the sealing moving frame 8 can be fixed to prevent the sealing moving frame 8 from moving and improve its stability.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
