Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a disassembly and assembly structure for a power monitoring device. Background Technology

[0002] Power monitoring devices play a vital role in power systems. They can monitor the operating parameters of power equipment in real time, such as voltage, current, and power, providing data support for the stable operation of the power system.

[0003] Traditional power monitoring devices are usually fixed with multiple screws. During installation, screwdrivers and other tools are needed to tighten each screw one by one, which is cumbersome and time-consuming. During disassembly, the screws also need to be loosened one by one, which is not only inefficient, but also difficult to operate in a confined installation space, and can easily lead to the loss or damage of screws.

[0004] To address the problems existing in the aforementioned technologies, a disassembly and assembly structure for a power monitoring device is proposed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present invention provides a disassembly and assembly structure for a power monitoring device, which overcomes the shortcomings of the prior art and solves the problems mentioned in the background art.

[0007] The guide assembly includes an asymmetrically arranged guide rail, the end of which is provided with a positioning pin hole, and an elastic positioning pin is provided inside the positioning pin hole. The mounting plate is provided with a positioning hole that is adapted to the elastic positioning pin.

[0008] The locking assembly includes a resiliently resettable buckle, a second spring between the buckle and the housing, and a snap-fit ​​part that matches the shape of the buckle. When the housing slides into the mounting plate along the guide rail, the positioning pin hole is embedded in the positioning hole to achieve pre-fixation, and the resiliently resettable buckle and the snap-fit ​​part engage to complete the final locking.

[0009] As a preferred embodiment of this utility model, the guide rail of the guide component has a T-shaped cross-section, and the inner wall of the slide groove is provided with a flange that matches the T-shaped guide rail, forming an anti-derailment structure.

[0010] As a preferred technical solution of this utility model, the locking assembly further includes a manual unlocking slide button. The slide button is connected to the buckle through a connecting rod. By sliding the slide button along the side of the housing, the connecting rod pushes the buckle to compress the second spring, causing it to disengage from the locking part.

[0011] As a preferred embodiment of this utility model, the elastic positioning pin is a hemispherical protrusion, the bottom of which is connected to the positioning pin hole via a first spring. A damping rubber ring is provided on the inner wall of the positioning hole to reduce the impact of the elastic positioning pin.

[0012] As a preferred technical solution of this utility model, an anti-misinstallation structure is provided between the housing and the mounting plate, including asymmetrically distributed guide components and / or elastic positioning pins and positioning holes of different diameters.

[0013] As a preferred technical solution of this utility model, the mounting plate is provided with heat dissipation holes on the back, and the housing is provided with an air guide shroud at the corresponding position, and the air guide shroud is provided with through holes, and the two are spliced ​​together to form a through ventilation channel.

[0014] As a preferred embodiment of this utility model, the edge of the housing is provided with a sealing strip, and the edge of the mounting plate is provided with a pressing groove that is interference-fitted with the sealing strip.

[0016] As a preferred embodiment of this utility model, the surface of the sliding button is provided with anti-slip texture, and the outer side of the sliding button is covered with a waterproof rubber sleeve.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. Through the cooperation of the guide component and the elastic positioning pin, the housing and the mounting plate are quickly aligned and pre-fixed. The elastic buckle of the locking component engages with the groove to complete the final locking, avoiding the cumbersome operation of traditional screw installation, while ensuring vibration resistance and anti-fall-off capability.

[0019] 2. The guide components adopt an asymmetrical distribution design to prevent incorrect installation direction and reduce the risk of operational errors. The manual unlock button, combined with anti-slip texture and waterproof sleeve, enables one-handed operation and is suitable for complex environments.

[0020] 3. The heat dissipation holes of the mounting plate and the air guide groove of the housing are spliced ​​to form a through air channel, which improves the heat dissipation efficiency. The sealing strip and the clamping groove are interference fit to adapt to outdoor or industrial environments.

The mounting plate 2 has a positioning hole 5 that is adapted to the elastic positioning pin 12.

[0032] The locking assembly includes a resiliently resettable snap-fit ​​18. A second spring 21 is provided between the snap-fit ​​18 and the housing 1. The locking part 6 is a slot that matches the shape of the snap-fit ​​18. When the housing 1 slides into the mounting plate 2 along the guide rail 10, the positioning pin hole 11 is embedded in the positioning hole 5 to achieve pre-fixation. The resiliently resettable snap-fit ​​18 and the locking part 6 engage to complete the final locking. Through the cooperation of the guide assembly and the elastic positioning pin, the housing and the mounting plate are quickly aligned and pre-fixed. The elastic snap-fit ​​of the locking assembly engages with the groove to complete the final locking, avoiding the cumbersome operation of traditional screw installation, while ensuring vibration resistance and anti-fall-off capability.

[0033] Specifically, the guide rail 10 of the guide component has a T-shaped cross-section, and the inner wall of the slide groove 3 is provided with a flange 4 that matches the T-shaped guide rail, forming an anti-derailment structure.

[0034] Specifically, the locking assembly also includes a manual unlocking slide button 19. The slide button 19 is connected to the buckle 18 via a connecting rod. By sliding the slide button 19 along the side of the housing 1, the buckle 18 is pushed by the connecting rod to compress the second spring 21, causing it to disengage from the locking part 6.

[0035] Specifically, the elastic positioning pin 12 is a hemispherical protrusion, and its bottom is connected to the positioning pin hole 11 via the first spring 13. The inner wall of the positioning hole 5 is provided with a damping rubber ring to reduce the impact of the elastic positioning pin 12.

[0036] Specifically, an anti-misinstallation structure is provided between the housing 1 and the mounting plate 2, including asymmetrically distributed guide components and / or elastic positioning pins 12 and positioning holes 5 of different diameters. The guide components adopt an asymmetrical distribution design to prevent incorrect installation direction and reduce the risk of operational errors.

[0037] Specifically, the mounting plate 2 has heat dissipation holes 8 on its back, and the housing 1 has an air guide shroud 15 at the corresponding position. The air guide shroud 15 has through holes. When the two are spliced ​​together, they form a through-ventilation channel. The heat dissipation holes of the mounting plate and the air guide groove of the housing are spliced ​​together to form a through-ventilation channel, thereby improving the heat dissipation efficiency.

[0038] Specifically, the edge of the housing 1 is provided with a sealing strip 14, and the edge of the mounting plate 2 is provided with a pressing groove 7 that is interference-fitted with the sealing strip 14. The sealing strip and the pressing groove are interference-fitted to adapt to outdoor or industrial environments. The quick-connect terminal cooperates with the limiting spring in the plug groove to fix the cable and prevent poor contact caused by pulling.

[0039] Specifically, the mounting plate 2 is provided with wiring terminals 9, and the housing 1 is provided with a plug groove 16 corresponding to the position of the wiring terminals 9. The plug groove 16 is provided with a limiting spring 17 for fixing the cable.

[0040] Specifically, the surface of the slider 19 is provided with anti-slip texture 20, and the outside of the slider 19 is covered with a waterproof rubber sleeve. The manual unlock button, combined with the anti-slip texture and the waterproof rubber sleeve, enables one-handed operation and is suitable for complex environments.

[0041] Working principle: Align the T-shaped guide rail 10 on the back of the housing 1 with the groove 3 of the mounting plate 2, and push the housing 1 along the direction of the groove 3. When the elastic positioning pin 12 at the end of the guide rail 10 slides into the positioning hole 5, the hemispherical protrusion is squeezed and reset, and a "click" sound is emitted to indicate that the pre-fixing is completed. Continue to push the housing 1 to the end, and the buckle 18 of the locking component is squeezed by the locking part 6 of the mounting plate 2 and then squeezes the second spring 21 upward, and finally snaps into the locking part 6 to complete the locking. Manually slide the unlocking button 19, and drive the buckle 18 to move upward and disengage from the groove of the locking part 6 through the connecting rod. Slide the housing 1 in the opposite direction to make the elastic positioning pin 12 exit the positioning hole 5, and the housing 1 and the mounting plate 2 can be separated.
