Description

Technical Field

[0001] This utility model belongs to the field of electrical panel installation technology, and in particular relates to an electrical panel device with a quick disassembly and assembly structure. Background Technology

[0002] In the field of electrical equipment manufacturing, the efficiency of installing and disassembling electrical panel devices directly affects equipment maintenance costs and operational safety. Electrical panels are installed on battery boxes or electrical boxes. These panels are used to control the operation of electrical equipment and typically include components such as switches, fuses, contactors, and indicator lights, controlling circuit voltage, current, and frequency. Traditional electrical panels are mostly fixed to the electrical housing with bolts. Installation requires tools to align the holes and tighten the bolts, and disassembly similarly requires gradually loosening the bolts. This makes the process cumbersome and time-consuming, especially in confined spaces or scenarios requiring frequent maintenance, resulting in low operational efficiency. Furthermore, small parts such as bolts and washers are easily scattered and lost after disassembly, leading to unstable electrical panel installation. Repeated disassembly and reassembly can also cause thread stripping or deformation of the mounting holes, resulting in gaps between the panel and the housing and reducing equipment operational stability. Utility Model Content

[0005] Furthermore, the positioning assembly includes a support plate, a positioning shaft, a positioning rod, a positioning block, and a transmission sleeve. The support plate is disposed on the inner wall of the electrical housing, the positioning block is disposed on the bottom surface of the connecting panel, and the positioning block is provided with a slot. The positioning shaft is vertically disposed on the support plate, and the transmission sleeve is hinged to the outer side of the positioning shaft. The transmission sleeve is provided with a positioning rod on one side and a lever on the other side. The positioning rod is slidably disposed in the slot, and the lever is slidably disposed in the limiting groove.

[0006] Furthermore, the lever is connected to the side wall of the limiting groove via a compression spring.

[0007] Furthermore, the arc-shaped plate is provided with an arc-shaped groove, and a limit rod is provided in the arc-shaped groove. The two ends of the limit rod are fixedly connected to the inner wall of the groove.

[0008] Furthermore, the bottom surface of the connecting frame is provided with a limiting hole, and the slide rod is slidably disposed within the limiting hole.

[0009] Furthermore, the top surface of the electrical housing is provided with two sets of symmetrically arranged first positioning holes, the surface of the connecting panel is provided with second positioning holes corresponding to the positions of the first positioning holes, and the snap-fit ​​component is provided through the first positioning holes and the second positioning holes.

[0010] Furthermore, the diameter of the second positioning hole is equal to the diameter of the first positioning hole, and the diameter of the second positioning hole is larger than the outer diameter of the connecting bracket.

[0011] Furthermore, a threaded sleeve is fitted onto the outer side of the top of the connecting frame, and the outer side of the threaded sleeve is screwed to the movable frame.

[0012] Furthermore, the bottom diameter of the movable frame is larger than the diameter of the second positioning hole.

[0013] Furthermore, the height of the slot is greater than the thickness of the positioning rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model utilizes a snap-fit ​​assembly with a press-type design, allowing operators to separate the connecting panel from the electrical housing simply by pressing the connecting rod. During installation, pressing the connecting rod causes the connecting collar to move axially, embedding the top of the arc-shaped plate into the sliding groove. Then, the snap-fit ​​assembly is inserted into the first positioning hole on the electrical housing. After releasing the connecting rod, a spring pushes the connecting collar, causing the top surface of the arc-shaped plate to contact the top of the inner side of the electrical housing, thus ensuring close contact between the bottom surface of the connecting panel and the electrical housing. Pressing the connecting rod again allows the arc-shaped plate to slide into the sliding groove, achieving disassembly. After disassembly, the connecting bracket remains in the second positioning hole on the connecting panel. The entire process requires no tools, significantly improving disassembly and assembly efficiency, solving the problem of cumbersome traditional bolt fixing steps, and avoiding the problem of lost parts.

[0016] 2. The limiting rod in the sliding groove of the snap-fit ​​assembly of this utility model constrains the movement path of the arc plate, avoiding excessive expansion or contraction that could cause structural damage. The moving frame rotates downward through the threaded sleeve to press down the connecting panel, ensuring that the connecting panel is in close contact with the electrical housing and eliminating the installation gap between the connecting panel and the electrical housing.

[0017] 3. The positioning component of this utility model uses a compression spring to provide elastic support for the lever. Moving the lever causes the rotating sleeve to rotate around the positioning shaft, so that the positioning rod is embedded in the slot of the positioning block at the bottom of the connecting panel, restricting the horizontal displacement of the connecting panel, thereby further reinforcing the position of the connecting panel and further improving the stability of the connecting panel installation.

[0018] 4. This utility model effectively prevents the connection panel from becoming loose due to repeated disassembly and assembly by using a dual reinforcement mechanism of snap-fit ​​components and positioning components. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present utility model can be combined with each other, and the described embodiments are only some embodiments of the present utility model, not all embodiments.

[0028] Detailed implementation method: See Figure 1-5This embodiment describes an electrical panel device with a quick-release structure, comprising an electrical housing 1, a connecting panel 2, a snap-fit ​​assembly 3, and a positioning assembly 4. The connecting panel 2 is detachably connected to the top surface of the electrical housing 1 via at least two sets of symmetrically arranged snap-fit ​​assemblies 3. The electrical housing 1 provides space for the installation and protection of electrical components. The main function of the connecting panel 2 is to enable electrical connection between the electrical housing 1 and other external devices or circuits. The connecting panel 2 is typically equipped with various electrical interfaces or terminals. The snap-fit ​​assembly 3 connects the connecting panel 2 to the electrical housing. Limiting grooves 11 are provided on both sides of the electrical housing 1, and the positioning assembly 4 is disposed within the limiting grooves 11. The positioning assembly 4 further reinforces the position of the connecting panel 2, improving the stability of the connecting panel 2 installation. The snap-fit ​​assembly 3 includes a connecting frame 31 and a connecting rod 33. The connecting frame 31 penetrates the connecting panel 2 and extends into the interior of the electrical housing 1. The connecting rod 33 is slidably connected inside the connecting frame 31. The connecting frame 31 tightly connects the connecting panel 2 and the electrical housing 1 together, while providing a secure connection for the internal connecting rod 33. The connecting rod 33 is slidably connected to the connecting frame 31, allowing it to be pushed. The connecting frame 31 has a groove 311 at its bottom, and the connecting rod 33 has a connecting collar 34 at its bottom. The connecting collar 34 slides along the axial direction of the groove 311. A sliding rod 38 is fixedly connected to the bottom surface of the connecting rod 33, and a spring 39 is sleeved on the sliding rod 38. Both ends of the spring 39 abut against the bottom surface of the connecting collar 34 and the bottom wall of the groove 311, respectively. The groove 311 provides a guide for the connecting collar 34 at the bottom of the connecting rod 33. The sliding trajectory and space ensure that the connecting collar 34 can slide smoothly along the axial direction of the slide groove 311; two connecting blocks 35 are symmetrically arranged on the outer side of the connecting collar 34, and the other side of the two connecting blocks 35 is hinged to the arc plate 36. The connecting blocks 35 play the role of connecting and transmitting force. The arc plate 36 has a certain curvature. When the connecting panel 2 is engaged with the electrical housing 1, the arc plate 36 is tightly fitted with the inner wall of the top surface of the electrical housing 1 under the action of the spring force of the spring 39, thereby achieving a stable engagement and ensuring the reliability of the connection between the connecting panel 2 and the electrical housing 1.

[0029] During the assembly and disassembly of the connecting panel 2, the synergistic action of the snap-fit ​​assembly 3 and the positioning assembly 4 enables the stable installation and quick disassembly of the connecting panel 2. The connecting panel 2 is mounted on the connecting panel 2 via the connecting bracket 31 and the connecting rod 33 of the snap-fit ​​assembly 3. When the connecting rod 33 is pressed, the connecting rod 33 drives the connecting collar 34 to slide inside the slide groove 311. At this time, the spring 39 is compressed, and the arc plate 36 slides downward and moves towards the connecting rod 33, so that the arc plate 36 is housed inside the slide groove 311, avoiding... When the connecting bracket 31 moves, the arc plate 36 may rub against the wall. In this case, the connecting panel 2 can be removed from the electrical housing 1. During installation, the connecting panel 2 is placed on the electrical housing 1, the connecting rod 33 is released, and the spring force of the spring 39 is used to push the connecting collar 34 and move the arc plate 36 away from the slide groove 311. The top of the arc plate 36 contacts the inner wall of the top surface of the electrical housing 1 to complete the snap-fit. At the same time, the positioning component 4 further reinforces the position of the connecting panel 2 on the electrical housing 1 in the limiting groove 11.

[0030] The positioning assembly 4 includes a support plate 41, a positioning shaft 42, a positioning rod 43, a positioning block 44, and a transmission sleeve 48. The support plate 41 is disposed on the inner side wall of the electrical housing 1 and is perpendicular to the side wall of the electrical housing 1. The positioning block 44 is disposed on the bottom surface of the connecting panel 2 and has a slot 45. The positioning shaft 42 is vertically disposed on the support plate 41, and the transmission sleeve 48 is hinged to the outer side of the positioning shaft 42. The positioning shaft 42 provides a rotation fulcrum for the transmission sleeve 48. The transmission sleeve 48 has a positioning rod 43 on one side and a lever 46 on the other side. The device can rotate around the positioning shaft 42, and the rotational force is transmitted to the positioning rod 43. The positioning rod 43 is slidably disposed in the slot 45. When the transmission sleeve 48 rotates, the positioning rod 43 slides along the slot 45 to realize the positioning, locking or releasing of the connecting panel 2. The lever 46 is slidably disposed in the limiting groove 11. The lever 46 is the operation interface. When it is necessary to disassemble the connecting panel 2, the lever 46 is moved, and the lever 46 drives the transmission sleeve 48 to rotate. The transmission sleeve 48 drives the positioning rod 43 to disengage from the slot 45, so that the connecting panel can be quickly removed. When installing the connecting panel 2, the lever 46 moves to align the positioning rod 43 with the slot 45 to complete the quick locking.

[0031] The lever 46 is connected to the side wall of the limiting groove 11 via a compression spring 47. The compression spring 47 enables the lever 46 to automatically reset after operation. When the lever 46 is slidable, the compression spring 47 is compressed, generating a reverse elastic force. When the lever 46 is released, the elastic force of the compression spring 47 drags the lever 46 back to its initial position, thereby driving the positioning rod 43 to reset via the transmission sleeve 48, so that the positioning rod 43 is embedded in the slot 45, completing the locking of the connecting panel 2.

[0032] The arc-shaped plate 36 has an arc-shaped groove 37, and a limit rod 371 is provided in the arc-shaped groove 37. The two ends of the limit rod 371 are fixedly connected to the inner wall of the slide groove 311. The limit rod 371 is mainly used to limit the movement trajectory of the arc-shaped plate 36. The arc-shaped groove 37 provides an arc-shaped sliding path for the arc-shaped plate 36.

[0033] The bottom surface of the connecting frame 31 is provided with a limiting hole 312. The slide rod 38 is slidably disposed in the limiting hole 312. The limiting hole 312 guides and restricts the movement of the slide rod 38, so that the slide rod 38 can only slide upward in the axial direction of the limiting hole 312, preventing the slide rod 38 from deflecting or shaking under the action of the spring force of the spring 39.

[0034] The top surface of the electrical housing 1 is provided with two sets of symmetrically arranged first positioning holes 12, and the surface of the connecting panel 2 is provided with second positioning holes 21 corresponding to the positions of the first positioning holes 12. The snap-fit ​​component 3 is provided through the first positioning holes 12 and the second positioning holes 21. The relative positions of the connecting panel 2 and the electrical housing 1 are initially positioned by the corresponding positions of the first positioning holes 12 and the second positioning holes 21, ensuring the accuracy of the installation of the connecting panel 2, and providing an installation path for the snap-fit ​​component 3, so as to realize the stable snap-fit ​​and quick disassembly of the connecting panel 2.

[0035] The diameter of the second positioning hole 21 is equal to the diameter of the first positioning hole 12, so that when the connecting panel 2 is aligned with the electrical housing 1, the snap-fit ​​component 2 can be accurately inserted to ensure the accuracy of positioning. The diameter of the second positioning hole 21 is larger than the outer diameter of the connecting bracket 31, which makes it easier for the connecting bracket 31 to be inserted into the interior of the second positioning hole 21 and the first positioning hole 12. After the snap-fit ​​component 3 is installed, the connecting bracket 31 can move moderately in the second positioning hole 21, which is convenient for fine-tuning the position of the connecting panel 2.

[0036] The threaded sleeve 32 is fitted onto the outer side of the top of the connecting frame 31. The outer side of the threaded sleeve 32 is screwed onto the movable frame 321. After the connecting panel 2 is connected to the electrical housing 1, the movable frame 321 is rotated so that the movable frame 321 contacts the top surface of the connecting panel 2, which enables the bottom surface of the connecting panel 2 to be in close contact with the electrical housing 1.

[0037] The bottom diameter of the movable frame 321 is larger than the diameter of the second positioning hole 21 to prevent the connecting frame 31 from coming off the connecting panel 2.

[0038] The height of the slot 45 is greater than the thickness of the positioning rod 43, ensuring that the positioning rod 43 can be smoothly inserted and slid within the slot 45.

[0039] The working principle of this utility model is as follows:

[0040] When the connecting panel 2 needs to be installed onto the electrical housing 1, first place the connecting panel 2 on top of the electrical housing 1, ensuring that the second positioning hole 21 is aligned with the first positioning hole 12 on the top surface of the electrical housing 1. Then, press the connecting rod 33. At this time, the connecting rod 33 drives the connecting collar 34 to slide downward inside the slide groove 311. Simultaneously, the arc plate 36 slides around the limiting rod 371, causing the arc plate 36 to move closer to the connecting rod 33 and embed the top of the arc plate 36 into the slide groove 311. At this time, the slide rod 38 slides into the limiting hole 312, which guides the slide rod 38. Then, insert the connecting bracket 31 into the first positioning hole 12, ensuring that the connecting bracket 31 is stably inserted. After releasing the connecting rod 33, the elastic force of the spring 39 pushes the connecting collar 34 upward, thereby causing the top of the arc plate 36 to move away from the slide groove 311, making the top surface of the arc plate 36 fit tightly. The inner top wall of the electrical housing 1 is securely engaged. Then, the rotating movable frame 321 is rotated. Since the threaded sleeve 32 is screwed to the movable frame 321, the rotation will cause the movable frame 321 to move downward and contact the top surface of the connecting panel 2, further pressing the connecting panel 2 and making the bottom surface of the movable frame 321 fit tightly against the electrical housing 1. After the connecting panel 2 is installed, the positioning component 4 begins to function. The compression spring 47 provides a rebound force to the lever 46, causing the lever 46 to drive the transmission sleeve 48 to rotate around the positioning shaft 42. This causes the positioning rod 43 to embed into the slot 45 on the positioning block 44 on the bottom surface of the connecting panel 2, thereby further reinforcing the position of the connecting panel 2 and improving the stability of the installation of the connecting panel 2. When disassembling, press the connecting rod 33 to separate the arc plate 36 from the inner wall of the electrical housing 1, and at the same time slide the lever 46 to disengage the positioning rod 43 from the slot 45, so that the connecting panel 2 can be easily removed.

[0041] Through the coordinated action of the snap-fit ​​component 3 and the positioning component 4, the entire device not only enables the quick assembly and disassembly of the connecting panel 2, but also ensures the stability and reliability of the installation, effectively improving the maintenance and repair efficiency of electrical equipment.
