Description

Technical Field

[0001] This application relates to the field of power distribution cabinet technology, and in particular to a power distribution cabinet with an adjustable door opening angle. Background Technology

[0002] As a crucial component of the power system, the design and function of the distribution cabinet directly impact the efficiency of power equipment protection and maintenance. When repairing the electrical equipment inside the distribution cabinet, the cabinet door must be opened first before accessing the equipment. However, due to variations in the location and size of the space occupied by the distribution cabinet, the opening angle of the cabinet can differ. Normally, the cabinet door is secured by a fixing mechanism when fully opened. But when the opening angle is limited, the fixing mechanism cannot hold the door in place. In this situation, the door is in a movable state and may rotate due to external factors, thus hindering maintenance personnel from performing their work. Utility Model Content

[0003] The purpose of this application is to provide a power distribution cabinet with an adjustable door opening angle, which can lock the opened cabinet door at different angles.

[0004] The power distribution cabinet with adjustable door opening angle provided in this application adopts the following technical solution:

[0005] A power distribution cabinet with an adjustable door opening angle, comprising:

[0006] Cabinet;

[0007] The cabinet doors are swivelly connected to the cabinet body;

[0008] A guide block is fixedly connected to the cabinet door, and a guide groove is provided through the top surface of the guide block, which is arranged along the width direction of the cabinet door;

[0009] The fixed rod is slidably disposed within the guide groove;

[0010] The connecting rod is hinged at one end to the cabinet and at the other end to the fixed rod;

[0011] A fixed block is slidably connected to the cabinet door and corresponds to the position of the guide block. The fixed block has several limiting grooves on the side near the guide block. The limiting grooves are spaced apart along the length of the fixed block. The fixed block can slide towards the guide block and insert the fixed rod into the limiting groove.

[0012] A limiting device is used to restrict the sliding of the fixed block;

[0013] A reset device is used to drive the fixed block to reset.

[0014] Optionally, the limiting device includes a limiting block and a first driving component. The limiting block has a slot, and the cabinet door has a first sliding groove and a second sliding groove. The first sliding groove is vertically arranged, and the second sliding groove is horizontally arranged. A slider is fixedly connected to the fixing block. The slider is slidably arranged in the first sliding groove and can slide from the first sliding groove into the second sliding groove and insert into the slot. The first driving component is used to drive the slider to slide from the first sliding groove into the second sliding groove.

[0015] The fixing rod is inserted into the limiting groove and can slide within the limiting groove.

[0016] Optionally, the first drive assembly includes a drive plate and a first elastic element. The drive plate is slidably connected to the cabinet door in a vertical direction. The first elastic element is disposed between the drive plate and the fixing block. One end of the first elastic element acts on the drive plate and the other end acts on the fixing block.

[0017] Optionally, the first drive assembly further includes a guide rod, and a guide groove is provided on the fixing block. One end of the guide rod is fixedly connected to the drive plate, and the other end is inserted into the guide groove and can slide within the guide groove.

[0018] Optionally, the reset device includes a reset block and a second driving component. The limiting block has a reset groove that communicates with the slot. The reset block is slidably disposed in the reset groove and can slide from the reset groove into the slot. The second driving component is used to drive the reset block to slide.

[0019] Optionally, the second drive assembly includes a drive rod and an extension plate. A drive groove is formed on the fixing block. The drive rod is slidably disposed in the drive groove. The extension plate is slidably disposed on the cabinet door and fixedly connected to the drive rod.

[0020] The reset block is provided with a guide slope, and the drive rod can push the reset block to slide through the guide slope.

[0021] Optionally, the second drive assembly further includes a second elastic element and a third elastic element. The second elastic element is disposed between the reset block and the reset slide groove. One end of the second elastic element acts on the reset block, and the other end acts on the inner wall of the reset slide groove.

[0022] The third elastic element acts on the extension plate at one end and on the cabinet door at the other end, and is used to drive the extension plate to slide in the vertical direction.

[0023] This application sets multiple limiting grooves on the fixed block and restricts the rotation of the cabinet door by cooperating with the fixed rod and the limiting grooves. This allows the cabinet door to have multiple fixing points, meaning that the cabinet door can be fixed at different angles. Therefore, even when space is limited or the opening angle of the cabinet door is limited, the cabinet door can still be fixed, reducing the interference of the cabinet door on the work of maintenance personnel and facilitating the construction of maintenance personnel.

[0024] Secondly, by moving the extension plate upward, the drive rod pushes the reset block to slide, thereby releasing the restriction on the fixed block. The process is convenient and the extension plate can be moved upward by simply lifting the foot. The unlocking process is simple and allows maintenance personnel to unlock quickly.

[0033] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 This application will be described in further detail below.

[0034] A power distribution cabinet with an adjustable door opening angle, as shown in the reference. Figure 1 and Figure 2 The system comprises a cabinet body 1, a cabinet door 2, a guide block 3, a fixing rod 5, a connecting rod 6, a fixing block 7, a limiting device 8, and a resetting device 9. The cabinet door 2 is rotatably connected to the cabinet body 1. The guide block 3 is horizontally fixed to the cabinet door 2, and its top surface has a through-hole guide groove 31, which runs along the width of the cabinet door 2. The fixing rod 5 is slidably disposed within the guide groove 31. One end of the connecting rod 6 is hinged to the cabinet body 1, and the other end is hinged to the fixing rod 5. During the rotation of the cabinet door 2, the connecting rod 6 rotates along with the cabinet door 2, simultaneously causing the fixing rod 5 to slide within the guide groove 31.

[0035] The fixing block 7 is slidably connected to the cabinet door 2 and corresponds to the position of the guide block 3. In this embodiment, the fixing block 7 is located below the guide block 3. The side of the fixing block 7 close to the guide block 3 is provided with a plurality of limiting grooves 73. The plurality of limiting grooves 73 are evenly spaced along the length direction of the fixing block 7. The fixing block 7 can slide towards the direction close to the guide block 3 and insert the fixing rod 5 into the limiting groove 73. The limiting device 8 is used to limit the sliding of the fixing block 7. The resetting device 9 is used to drive the fixing block 7 to reset.

[0036] Specifically, during the opening of cabinet door 2, the fixing rod 5 slides within the guide groove 31. When cabinet door 2 rotates to a certain angle, the fixing rod 5 aligns with one of the limiting grooves 73. When it is necessary to lock cabinet door 2, the fixing block 7 is slid upwards, thereby inserting the fixing rod 5 into the limiting groove 73. The limiting groove 73 restricts the sliding of the fixing rod 5 within the guide groove 31, thus limiting the rotation of the drying process, i.e., restricting the rotation of cabinet door 2, and reducing the impact of cabinet door 2 on maintenance personnel.

[0037] Reference Figure 2 and Figure 3 Furthermore, the fixing block 7 includes a vertical part 71 and a horizontal part 72. A limiting groove 73 is formed on the horizontal part 72. One end of the fixing block 7 is fixed on the horizontal part 72 and the other end extends upward. Since the horizontal part 72 is set too low, it is inconvenient for the staff to push the horizontal part 72 upward. By setting the vertical part 71, the height of the vertical part 71 is more suitable for the height of the staff, so that the staff can easily drive the vertical part 71 to slide, thereby driving the horizontal part 72 to slide.

[0038] Reference Figure 4 , Figure 5 and Figure 6The length of the limiting groove 73 is greater than the outer diameter of the fixing rod 5. In this embodiment, the length of the limiting groove 73 is twice the outer diameter of the fixing rod 5. The fixing rod 5 is inserted into the limiting groove 73 and can slide within the limiting groove 73.

[0039] The limiting device 8 includes a limiting block 81 and a first driving component 82. The limiting block 81 has a slot 811. The cabinet door 2 has a first sliding groove 21 and a second sliding groove 22. The first sliding groove 21 is vertically arranged, and the second sliding groove 22 is horizontally arranged. The fixing block 7 is provided with a slider 4, that is, the slider 4 is fixed on the vertical part 71. The slider 4 is slidably arranged in the first sliding groove 21 and can slide from the first sliding groove 21 into the second sliding groove 22 and be inserted into the slot 811. The first driving component 82 is used to drive the slider 4 to slide from the first sliding groove 21 into the second sliding groove 22.

[0040] Specifically, when cabinet door 2 needs to be fixed, the operator pulls the vertical part 71 upward, causing the slider 4 to slide upward. Simultaneously, the horizontal part 72 slides upward. When the slider 4 slides to the position corresponding to the second slide groove 22, the horizontal part 72 aligns with the slot 811. At this point, the first drive assembly 82 pushes the vertical part 71 to slide horizontally, thereby causing the slider 4 to slide from the first slide groove 21 into the second slide groove 22, i.e., the horizontal part 72 is inserted into the slot 811, thus restricting the downward sliding of the horizontal part 72. This maintains the state of the fixing rod 5 inserted into the limiting groove 73, thereby limiting the cabinet door 2. When the horizontal part 72 aligns with the slot 811, the fixing rod 5 is inserted into the limiting groove 73. During the insertion of the horizontal part 72 into the slot 811, the fixing rod 5 slides within the limiting groove 73.

[0041] The first driving assembly 82 includes a driving plate 821 and a first elastic element 822. The driving plate 821 is slidably connected to the cabinet door 2 in a vertical direction. The first elastic element 822 is disposed between the driving plate 821 and the fixing block 7. One end of the first elastic element 822 acts on the driving plate 821, and the other end acts on the fixing block 7. In this embodiment, the first elastic element 822 is a spring, and both ends of the first elastic element 822 are fixedly connected to the fixing block 7 and the driving plate 821, respectively. When the operator pulls the driving plate 821 upward, it drives the vertical part 71 to slide upward. During this process, the first elastic element 822 is always in a compressed state. When the slider 4 corresponds to the position of the second slide groove 22, the first elastic element 822 returns to its original position, pushing the vertical part 71 to slide horizontally, so that the slider 4 slides into the second slide groove 22.

[0042] Furthermore, to facilitate the staff in pushing the drive board 821 to slide upward, a handle is fixedly connected to the drive board 821.

[0043] Furthermore, the first drive assembly 82 also includes a guide rod 823. A guide groove 74 is provided on the fixing block 7. One end of the guide rod 823 is fixedly connected to the drive plate 821, and the other end is inserted into the guide groove 74 and can slide within it. During the horizontal sliding of the vertical section, the guide rod 823 remains within the guide groove 74. During the vertical sliding of the drive plate 821, the guide rod 823 drives the vertical section 71 to slide vertically, reducing the radial bending of the first elastic element 822 during the vertical sliding of the drive plate 821.

[0044] Reference Figure 5 , Figure 6 and Figure 7 The reset device 9 includes a reset block 91 and a second drive assembly 92. A reset groove 812 is provided on the limiting block 81, which communicates with the slot 811. The reset block 91 is slidably disposed within the reset groove 812 and can slide from the reset groove 812 into the slot 811. The second drive assembly 92 drives the reset block 91 to slide. When it is necessary to release the restriction on the cabinet door 2, the second drive assembly 92 pushes the reset block 91 into the slot 811, thereby pushing the horizontal part 72 out of the slot 811 and releasing the vertical restriction on the horizontal part 72. At this time, the drive plate 821 is slid downwards, causing the horizontal part 72 to abut against the side wall of the limiting block 81, thus completing the unlocking of the cabinet door 2.

[0045] The second drive assembly 92 includes a drive rod 921 and an extension plate 922. A drive groove 813 is formed on the limiting block 81, vertically positioned and communicating with a reset groove 812. The drive rod 921 is slidably disposed within the drive groove 813. The extension plate 922 is slidably disposed on the cabinet door 2 in a vertical direction and fixedly connected to the drive rod 921. A guide ramp 911 is provided on the reset block 91, allowing the drive rod 921 to push the reset block 91 to slide via the guide ramp 911. When it is necessary to push the reset block 91 to slide, the extension plate 922 is slid upwards, thereby causing the drive rod 921 to slide upwards, making the drive rod 921 grounded with the guide ramp 911, and pushing the reset block 91 to slide via the guide ramp 911. Because the extension plate 922 extends towards the edge of the door panel, it is convenient for workers to push the extension plate 922 upwards with their feet, facilitating the unlocking of the cabinet door 2.

[0046] Furthermore, the second drive assembly 92 also includes a third elastic element 924. A third slide groove 23 is provided on the cabinet door 2, and the extension plate 922 is slidably disposed within the third slide groove 23. One end of the second elastic element 923 acts on the inner wall of the third slide groove 23, and the other end acts on the extension plate 922. When the extension plate 922 slides upward, it compresses the second elastic element 923. When the thrust on the extension plate 922 is released, the second elastic element 923 returns to its original position, causing the extension plate 922 to reset. Compared to resetting by the weight of the extension plate 922 itself, resetting by the second elastic element 923 is faster and more stable. In this embodiment, the third elastic element 924 is a spring, with one end fixed to the inner wall of the third slide groove 23 and the other end fixed to the extension plate 922.

[0047] Furthermore, the second drive assembly 92 also includes a second elastic element 923, which is disposed between the reset block 91 and the reset slide 812. One end of the second elastic element 923 acts on the reset block 91, and the other end acts on the inner wall of the reset slide 812. When the reset block 91 pushes the horizontal part 72 out of the slot 811, the drive rod 921 is reset under the action of the extension plate 922, and the reset block 91 is reset under the action of the second elastic element 923. In this embodiment, the second elastic element 923 is a spring, and one end of the second elastic element 923 is fixed to the reset block 91, and the other end is fixed to the inner wall of the reset slide 812. The setting of the second elastic element 923 facilitates the reset of the reset block 91, thereby facilitating the next fixation of the cabinet door 2.
