Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a power distribution cabinet with an interlocking mechanism. Background Technology

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are few circuits. Motor control centers are used in situations where the load is concentrated and there are many circuits. They distribute the electrical energy of a certain circuit of the previous level of power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load. Currently, most distribution cabinets are integrated structures, which cannot meet the needs of customers for multi-volume distribution cabinets and reduce the practicality of distribution cabinets. At this time, there is a need for distribution cabinets that can be expanded and assembled. However, existing assembled distribution cabinets are fixed to each other with bolts, which is a cumbersome and complex process with low installation efficiency.

[0003] For example, a Chinese patent document discloses an expandable combined power distribution cabinet with an interlocking mechanism (publication number: CN218216202U). Although this patent uses an interlocking mechanism to drive the lower connecting plate to rotate, the lower connecting plate drives the lower connecting arm and the lower connecting block to rotate together until the lower connecting arm engages with the upper connecting block and the lower connecting block engages with the upper connecting arm, the power distribution cabinet can be fixedly installed in pairs. The process is simple and convenient, and the installation efficiency is high.

[0004] However, it uses vertical and horizontal bevel gears for locking and connecting, which requires repeated rotation during connection and disassembly, making the operation cumbersome. Furthermore, the entire mechanism is installed inside the cabinet, occupying a large amount of space and resulting in low space utilization inside the cabinet. In addition, there is a large gap between the two cabinets, which not only easily accumulates dust but also increases the overall space occupied by the cabinet, resulting in low practicality.

[0005] Therefore, we propose a power distribution cabinet with an interlocking mechanism. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies. Currently, locking connections are achieved through the transmission of vertical and horizontal bevel gears, which requires repeated rotation during connection and disassembly, making the operation cumbersome. Furthermore, the entire mechanism is installed inside the cabinet, occupying a significant amount of space and resulting in low space utilization within the cabinet. Additionally, there is a large gap between the two cabinet connections, which not only easily accumulates dust but also increases the overall space occupied by the cabinet, leading to low practicality.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A power distribution cabinet with an interlocking mechanism includes a power distribution cabinet body. The back of the power distribution cabinet body is provided with symmetrically distributed limiting grooves. A limiting slider is slidably sleeved on the inner wall of the limiting groove. A moving block is fixedly connected to the back of the limiting slider. A limiting block is fixedly connected to one side surface of the moving block. A locking groove is provided on the upper surface of the limiting block. A through groove is provided at one end of the locking groove.

[0009] The upper surface of the movable block is provided with an elastic locking device, and the elastic locking device includes a first support, the lower surface of the first support being fixedly connected to the upper surface of the movable block.

[0010] Preferably, a fixing block is fixedly connected to the back of the power distribution cabinet body, a drive rod is movably sleeved on the inner wall of the fixing block, and a pressing block is fixedly connected to one end of the drive rod.

[0011] Preferably, the other end of the drive rod is fixedly connected to a second support, and the inner wall of the second support is hinged with symmetrically distributed swing rods by a pin. One end of the swing rod is hinged to the inner wall of the first support by a pin, and a support spring is movably sleeved on the outer surface of the drive rod.

[0012] Preferably, one end of the support spring is fixedly connected to the lower surface of the pressing block, the other end of the support spring is fixedly connected to the upper surface of the fixing block, and a support block is fixedly connected to the back of the distribution cabinet body.

[0013] Preferably, the upper surface of the support block is fixedly connected with symmetrically distributed insertion rods, the outer surface of the insertion rods is provided with an annular limiting groove, and the front of the distribution cabinet body is hinged with a cabinet door.

[0014] Preferably, the upper surface of the cabinet door is provided with a connection slot, and the lower surface of the cabinet door is fixedly connected with a connection block.

[0015] Preferably, the lower surface of the power distribution cabinet body is fixedly connected with guide columns arranged in a rectangular array, and the upper surface of the power distribution cabinet body is provided with guide grooves arranged in a rectangular array.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this utility model, the elastic locking device enables the mutual locking of two adjacent power distribution cabinet bodies. This not only makes disassembly and assembly convenient, but also allows the two power distribution cabinet bodies to fit together, reducing the space occupied and not occupying the internal space of the power distribution cabinet body, thereby improving the utilization rate of the internal space of the cabinet and thus improving its practicality.

[0028] like Figure 1-5 As shown, this utility model provides a technical solution: a power distribution cabinet with an interlocking mechanism, including a power distribution cabinet body 1, a symmetrically distributed limiting slide groove 2 on the back of the power distribution cabinet body 1, a limiting slider 3 slidably sleeved on the inner wall of the limiting slide groove 2, a moving block 4 fixedly connected to the back of the limiting slider 3, a limiting block 5 fixedly connected to one side surface of the moving block 4, the moving block 4 cooperates with the limiting slider 3 through the limiting slide groove 2 to drive the limiting block 5 to move stably, a locking slide groove 6 is provided on the upper surface of the limiting block 5, and a through groove 7 is provided at one end of the locking slide groove 6;

[0029] The upper surface of the movable block 4 is provided with an elastic locking device, and the elastic locking device includes a first support 8, the lower surface of the first support 8 being fixedly connected to the upper surface of the movable block 4. Example

[0030] like Figure 1-5 As shown, this utility model provides a technical solution: a fixing block 81 is fixedly connected to the back of the power distribution cabinet body 1, a drive rod 82 is movably sleeved on the inner wall of the fixing block 81, a pressing block 83 is fixedly connected to one end of the drive rod 82, and the fixing block 81 plays a guiding role in the movement of the drive rod 82.

[0031] The other end of the drive rod 82 is fixedly connected to a second support 84. The inner wall of the second support 84 is hinged with a pin to a symmetrically distributed swing rod 85. One end of the swing rod 85 is hinged to the inner wall of the first support 8 through a pin. A support spring 86 is movably sleeved on the outer surface of the drive rod 82. The downward movement of the second support 84 is oscillating through the swing rod 85 to make the first support 8 perform a limited translation.

[0032] One end of the support spring 86 is fixedly connected to the lower surface of the pressing block 83, and the other end of the support spring 86 is fixedly connected to the upper surface of the fixing block 81. A support block 87 is fixedly connected to the back of the distribution cabinet body 1. The elastic force of the support spring 86 drives the pressing block 83 to reset and move.

[0033] The upper surface of the support block 87 is fixedly connected with symmetrically distributed plug rods 88. The outer surface of the plug rods 88 is provided with an annular limiting groove 89. The front of the distribution cabinet body 1 is hinged with a cabinet door 810. The support block 87 serves to fix and support the plug rods 88.

[0034] The upper surface of the cabinet door 810 is provided with a connecting slot 811, and the lower surface of the cabinet door 810 is fixedly connected with a connecting plug 812. The cooperation between the connecting plug 812 and the connecting slot 811 enables multiple cabinet doors 810 to open and close synchronously, thereby improving the efficiency of subsequent inspection and maintenance.

[0035] The lower surface of the power distribution cabinet body 1 is fixedly connected with guide posts 813 arranged in a rectangular array, and the upper surface of the power distribution cabinet body 1 is provided with guide grooves 814 arranged in a rectangular array. The cooperation between the guide posts 813 and the guide grooves 814 serves to guide and position the connection when the two power distribution cabinet bodies 1 are connected and locked.

[0036] The elastic locking device enables the two adjacent power distribution cabinet bodies 1 to be locked together, which not only makes disassembly and assembly convenient, but also allows the two power distribution cabinet bodies 1 to fit together, reducing the space occupied and not occupying the internal space of the power distribution cabinet body 1, thereby improving the utilization rate of the internal space of the cabinet and thus improving its practicality.

[0037] The working process of this utility model:

[0038] Step 1: During installation, the pressing block 83 drives the drive rod 82 to move. The movement of the drive rod 82 causes the support spring 86 to contract. The downward movement of the drive rod 82 drives the second support 84 to move downward. The downward movement of the second support 84 causes the two first supports 8 to move away from each other through the swing of the swing rod 85. The first support 8 drives the moving block 4 to move through the cooperation of the limiting slide groove 2 and the limiting slider 3. The movement of the moving block 4 drives the limiting block 5 to move, so that the through groove 7 on the limiting block 5 moves to be on the same vertical axis as the insertion rod 88.

[0039] Step two: The distribution cabinet body 1 is lifted and placed above another distribution cabinet body 1 to be installed via the guide groove 814 and guide post 813. Simultaneously, the connecting plug 812 is inserted into the connecting slot 811 on the lower distribution cabinet body 1, and the plug rod 88 is inserted into the through groove 7 for connection and positioning. The pressing block 83 is then released, and the second support 84 rises and resets due to the elastic force of the support spring 86. This rise and reset movement of the second support 84, through the cooperation of the swing rod 85, causes the two first supports 8 to move relative to each other. This, in turn, causes the moving block 4 to move the limiting block 5. The movement of the limiting block 5 causes the locking slide 6 to contact the inner wall of the annular limiting groove 89, thus limiting the plug rod 88 and completing the locking between the two distribution cabinet bodies 1. Furthermore, the cooperation between the connecting plug 812 and the connecting slot 811 allows multiple cabinet doors 810 to open simultaneously, facilitating subsequent operation and maintenance.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
