Description

Technical Field

[0001] This utility model relates to the field of insulating cover technology, specifically to a modular and detachable insulating cover. Background Technology

[0002] Insulating covers are a type of insulating safety protection product used for electrical equipment terminals or exposed live parts. They are usually made of silicone rubber, heat-shrinkable materials, or polymer insulating materials. Their core function is to prevent short circuits, grounding, or electric shock accidents caused by human contact, small animals connecting to the device, foreign objects entering, wet flashover, salt spray, chemical corrosion, etc., through physical isolation, thereby ensuring the safe operation of the power system.

[0003] Most existing insulating covers are one-piece structures. When a part of the cover is damaged or needs to be upgraded, the entire cover must be replaced because the part cannot be replaced separately. This greatly increases the cost of use, the user's operating costs, and the difficulty of maintenance. At the same time, the one-piece structure occupies a lot of space during transportation and storage, and the transportation and storage costs are also relatively high.

[0004] For example, the insulating cover for link pile heads disclosed in CN206163211U includes an insulating cover body that forms a link pile receiving cavity in the middle. The insulating cover body gradually narrows from one end to the other along the length direction to form a funnel-shaped structure, with the larger end extending outward to form a link pile head clearance opening, and the smaller end extending outward to form a cable outlet. A slit is opened on one side wall of the insulating cover body along the length direction, and the two sides of the slit extend outward to form side wings. Several through holes are opened at intervals on the two side wings, and connecting pins for tightly fitting the two side wings are installed in the through holes. Although this patent allows for disassembly and assembly, it requires passing the connecting pins through the through holes one by one to achieve a tight fit between the side wings. The operation process is relatively cumbersome, especially in the case of limited space. It is difficult for operators to operate the connecting pins accurately, and the connecting pins are prone to falling off or not being able to be accurately inserted into the through holes. Due to the many difficulties in the installation process, operators need to spend a long time to complete the installation of the cover, resulting in low installation efficiency.

[0005] Therefore, it is necessary to invent a modular, detachable insulating cover to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a modular, detachable insulating cover, which solves the problem of inconvenience in disassembly and assembly.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a modular detachable insulating cover, comprising a cover one and a cover two, wherein the cover one is installed on top of the cover two by a plug-in connection, and the connection between the cover one and the cover two is provided with a limiting structure for preventing relative displacement between the two and a locking structure for locking the connection state. The limiting structure is a limiting component provided on the front, back, left, and right sides of the connection between the cover one and the cover two, and the locking structure is a locking component provided in the middle of the front and back ends of the connection between the cover one and the cover two.

[0008] Preferably, the left and right sides of the first and second protective covers are symmetrically provided with wiring grooves, which provide dedicated space for wiring.

[0009] Preferably, the bottom of the first protective cover is provided with a plug at each of the four corners, and the top surface of the second protective cover is provided with a matching slot at the contact position with the plug. The plug and slot are used to connect and install the first protective cover and the second protective cover.

[0010] Preferably, the limiting component includes a fixing block, which is fixedly installed on the second protective cover. An adjusting rod is connected to the top surface of the fixing block and extends through the second protective cover to the top. A limiting block is provided at the threaded end of the adjusting rod. The inner thread of the limiting block and the outer thread of the adjusting rod are engaged to provide a stable support base for the entire limiting component, ensuring that the limiting component can be firmly fixed on the second protective cover, thereby effectively performing the limiting function.

[0011] Preferably, the protective cover has a limiting groove at the position corresponding to the limiting block, which works with the limiting block to achieve the horizontal limiting function.

[0012] Preferably, the locking assembly includes a connecting plate, which is bolted to the second protective cover. The connecting plate has a shaft, and a locking cover is hinged to the shaft. When locked, the locking cover is fitted onto the connecting end of the first and second protective covers. A locking screw is threaded through the locking cover and extends to the first protective cover, allowing the locking cover to rotate around the shaft and switch between locked and unlocked states.

[0013] Preferably, the first protective cover has a screw hole that matches the locking screw at the position of the locking screw. By rotating the locking screw, the first protective cover and the second protective cover can be locked or unlocked in the connected state.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model improves the flexibility and convenience of using the protective cover through a modular and detachable design: the protective cover one is installed on top of the protective cover two by plugging it in. This plugging structure is simple and easy to operate, and can quickly achieve the initial assembly of the protective cover. Moreover, the modular design allows the protective cover one and the protective cover two to be replaced or maintained separately according to the actual use scenario and needs, without the need to replace the entire protective cover, which greatly reduces the cost of use and maintenance difficulty, and also facilitates the transportation and storage of the protective cover.

[0016] 2. This utility model achieves convenient and precise vertical insertion and installation of the first and second protective covers through the cooperation of the plug and the slot, laying the foundation for subsequent operations. Then, through the limiting component, the adjusting rod and the limiting block are threadedly engaged, and the limiting block is rotated to achieve reliable horizontal limiting and convenient unlocking. Finally, with the help of the locking component, the locking cover plate and locking screw and other components, the connection state of the protective covers is firmly locked, which further enhances the firmness of the connection between the first and second protective covers, prevents loosening, and provides effective insulation protection for the internal equipment.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-6 The modular detachable insulating cover shown includes a cover 1 and a cover 2. The cover 1 is installed on top of the cover 2 by plugging it in. The cover 1 and the cover 2 are symmetrically provided with wiring grooves 3 on the left and right sides. The connection between the cover 1 and the cover 2 is provided with a limiting structure to prevent relative displacement between the two and a locking structure to lock the connection state. The limiting structure is a limiting component 6 provided on the front, back, left and right sides of the connection between the cover 1 and the cover 2. The locking structure is a locking component 7 provided in the middle of the front and back ends of the connection between the cover 1 and the cover 2.

[0027] In this embodiment, by setting limiting components 6 on the front, back, left, and right sides of the connection between the first protective cover 1 and the second protective cover 2, the first protective cover 1 and the second protective cover 2 can be limited from multiple directions. The setting of locking components 7 further enhances the firmness of the connection between the first protective cover 1 and the second protective cover 2. This method can effectively improve the ease of disassembly and assembly of the first protective cover 1 and the second protective cover 2 while ensuring the stability after connection.

[0028] The bottom of the first protective cover 1 has four corners with inserts 4, and the top surface of the second protective cover 2 has a matching slot 5 at the contact position with the inserts 4. The inserts 4 and the slots 5 are used to connect and install the first protective cover 1 and the second protective cover 2.

[0029] In this embodiment, the cooperation between the plug 4 and the slot 5 enables the convenient plug-in installation of the first protective cover 1 and the second protective cover 2, allowing them to be initially combined together. This provides a basis for subsequent limiting and locking operations, ensuring the initial positioning and connection of the first protective cover 1 and the second protective cover 2 in the vertical direction.

[0030] The limiting component 6 includes a fixing block 601, which is fixedly installed on the second protective cover 2. An adjusting rod 602 is connected to the top surface of the fixing block 601 and extends through the second protective cover 2 to the top. A limiting block 603 is provided at the threaded end of the adjusting rod 602. The inner thread of the limiting block 603 is engaged with the outer thread of the adjusting rod 602. A limiting groove 604 is provided at the position of the first protective cover 1 corresponding to the limiting block 603.

[0031] In this embodiment, the fixing block 601 provides stable support for the limiting component 6. By rotating the limiting block 603, it moves up and down along the axis of the adjusting rod 602 and changes the circumferential direction. When the limiting block 603 moves to be perpendicular to the circumferential direction of the limiting groove 604, it blocks the opening of the limiting groove 604 and forms an effective blockage in the horizontal direction for the first protective cover 1 and the second protective cover 2, preventing relative displacement between them. When the limiting block 603 moves to be parallel to the circumferential direction of the limiting groove 604, the horizontal limiting is released, which facilitates the disassembly of the first protective cover 1 and the second protective cover 2.

[0032] The locking assembly 7 includes a connecting plate 701, which is bolted to the second protective cover 2. The connecting plate 701 has a shaft 702, and a locking cover 703 is hinged to the shaft 702. When locked, the locking cover 703 is fitted onto the connection end of the first protective cover 1 and the second protective cover 2. A locking screw 704 is threaded through the locking cover 703 and extends to the first protective cover 1. The first protective cover 1 has a screw hole 705 at the position corresponding to the locking screw 704. By rotating the locking screw 704, it can be screwed into or out of the screw hole 705, thereby locking or unlocking the connection between the first protective cover 1 and the second protective cover 2.

[0033] In this embodiment, the connecting plate 701 provides an installation base for the locking assembly 7. When locked, the locking cover 703 is fitted onto the connection end of the first cover 1 and the second cover 2, serving to wrap and fix it. By rotating the locking screw 704, it can be screwed into or out of the screw hole 705, thereby locking or unlocking the connection between the first cover 1 and the second cover 2, further enhancing the firmness of the connection between the first cover 1 and the second cover 2, preventing the cover from loosening when subjected to external impact or vibration, and providing continuous and effective insulation protection for the internal electrical equipment or lines.

[0034] Working principle of this utility model:

[0035] Refer to the instruction manual appendix Figure 1-6When using this utility model, if it is necessary to install the first protective cover 1 and the second protective cover 2, firstly, align the inserts 4 at the four corners of the bottom surface of the first protective cover 1 with the slots 5 on the top surface of the second protective cover 2, and slowly press down the first protective cover 1 so that the inserts 4 are fully inserted into the slots 5, thus achieving the initial positioning and connection of the first protective cover 1 and the second protective cover 2 in the vertical direction. Then, rotate the limiting block 603 in the limiting assembly 6. The limiting block 603 will move along the axial direction of the adjusting rod 602, rotating the limiting block 603 until it is circumferentially perpendicular to the limiting groove 604 corresponding to the position on the first protective cover 1. At this time, the limiting block... The opening of the limiting groove 604 is blocked by 603, which effectively blocks the shield 1 and shield 2 in the horizontal direction to prevent relative displacement between them. Finally, the locking cover 703 in the locking assembly 7 is rotated to rotate around the shaft 702 to the locked state, that is, the locking cover 703 is fitted on the connecting end of shield 1 and shield 2, and the locking screw 704 on the locking cover 703 is rotated to screw into the corresponding screw hole 705 on shield 1, thereby locking the connection state of shield 1 and shield 2 and further enhancing the firmness of the connection.

[0036] When it is necessary to disassemble the first cover 1 and the second cover 2, firstly, rotate the locking screw 704 in the locking assembly 7 so that it unscrews from the screw hole 705 on the first cover 1, thereby releasing the lock of the connection between the first cover 1 and the second cover 2. Then, rotate the locking cover 703 so that it rotates around the shaft 702 to the unlocked state, so that the locking cover 703 is no longer fitted on the connection end of the first cover 1 and the second cover 2. Next, rotate the limiting block 603 in the limiting assembly 6 so that it moves along the axial direction of the adjusting rod 602 and rotates to be circumferentially parallel to the limiting groove 604 at the corresponding position on the first cover 1. At this time, the limiting block 603 no longer blocks the opening of the limiting groove 604, thereby releasing the horizontal limiting. Finally, lift the first cover 1 upward so that the inserts 4 at the four corners of the bottom surface of the first cover 1 are pulled out from the slots 5 on the top surface of the second cover 2, thereby separating the first cover 1 and the second cover 2.
