Description

A dustproof distribution cabinet

Technical Field

The utility model relates to the technical field of power distribution cabinets, and more specifically, to a dustproof power distribution cabinet.

Background technique

The power distribution cabinet is a general term for the motor control center. With the rapid development of the power industry, power distribution cabinets are widely used in all walks of life. During the use of the power distribution cabinet, in order to improve the protection and service life of the internal accessories of the power distribution cabinet, a dust screen is often required in the power distribution cabinet. After long-term use, a large amount of dust will adhere to the surface of the dust screen, which needs to be disassembled, cleaned and replaced. The installation and removal of the dust screen of the existing power distribution cabinet is troublesome, time-consuming and labor-intensive, and it is not convenient for later disassembly, cleaning and replacement, and the practicality is not good.

In order to solve the above problems, a Chinese patent with a publication (announcement) number of CN217158980U discloses a power distribution cabinet for a machining center, which includes a cabinet body and a fixed frame. A dustproof net is arranged inside the fixed frame. Heat dissipation ports are provided on both the left and right surfaces of the cabinet body. A groove is provided on the outer side of the heat dissipation port to cooperate with the fixed frame. Card slots are provided on both the upper and lower surfaces of the fixed frame. Cavities are provided on both the upper and lower surfaces of the inner wall of the groove. A card block is movably arranged inside the cavity to cooperate with the card slot. Two movable grooves are provided on both the left and right surfaces of the cabinet body. A piston rod is provided inside the movable groove. A through hole is provided between the movable groove and the cavity. One end of the piston rod passes through the through hole and is connected to the card block. An adjusting plate is connected to the other end of the plug rod, and a spring is sleeved on the outside of the piston rod, and the two ends of the spring are respectively connected to the adjusting plate and the inner wall of the movable groove. Through the elastic action of the spring, it is convenient to squeeze the card block into the card slot, and then fix the fixed frame, which is convenient for the later disassembly, cleaning and replacement of the dustproof net. However, each time the dustproof net is loaded and unloaded, the two adjusting plates 10 need to be controlled synchronously to pull the piston rod 9 away from the groove 4, so as to drive the card block 7 to move into the cavity 5 to disengage from the card slot 6, so as to remove the fixed frame. Since two-handed operation is required, it is impossible to unlock and take and put the fixed frame at the same time by only one staff member, and two people are required to assist in completing it together, and the operation method is relatively cumbersome.

Please refer to Figures 1-4, a dustproof distribution cabinet according to an embodiment of the utility model includes a cabinet body 1, an assembly opening 10 is opened on the right side of the cabinet body 1 and a fixed frame 2 is built in the assembly opening 10, two clamping rails 20 are correspondingly arranged on the inner side of the fixed frame 2, and a positioning rod 3 is slidably arranged on the inner wall of the cabinet body 1 and located above the assembly opening 10. The positioning rod 3 is an inverted U-shaped structure and clamping rail sleeves 30 are arranged at both ends. The two clamping rail sleeves 30 respectively correspond to the positions of the two clamping rails 20 and form a locking or unlocking with the clamping rails 20.

When in use, when installing the fixing frame 2, the positioning rod 3 is pulled upward to cause the two clamping rail sleeves 30 to move upward until the horizontal position of the two clamping rail sleeves 30 is higher than the preset position of the clamping rail strips 20, and then the fixing frame 2 is pushed into the assembly opening 10 and reaches the specified installation position. When the fixing frame 2 is in the installed state, the two clamping rail strips 20 on the inner side thereof (connected to the fixing frame 2 through the fixing column) extend into the inner side of the cabinet body 1. At this time, the two positioning rods 3 are controlled to return to the initial position. During the returning process of the positioning rods 3, the clamping rail sleeves 30 are caused to be inserted into the clamping rail strips 20. The installation of the fixing frame 2 is completed through the limit locking between the clamping rail sleeves 30 and the clamping rail strips 20; when it is necessary to disassemble and replace the fixing frame 2, the positioning rod 3 is pulled upward to cause the two clamping rail sleeves 30 to disengage from the contact with the two clamping rail strips 20, and the fixing frame 2 can be removed at this time;

The utility model only needs one hand of the staff to operate the positioning pull rod 3 and the other hand to install and remove the fixing frame 2. The operation process is convenient and quick and can be completed by a single person.

The clamping rail 20 is a vertical strip structure and has two arc-shaped slots 21 on the left and right sides respectively. The clamping rail sleeve 30 is a vertical U-shaped structure and has two arc-shaped clamping ribs 31 on the left and right inner walls respectively that are adapted to the arc-shaped slots 21. Both ends of the positioning rod 3 are connected to fixed cover plates 32 and are fixedly connected to the clamping rail sleeve 30 through the fixed cover plates 32. A holding block 33 is fixedly provided at the center of the transverse part of the positioning rod 3. Two guide frames 34 are fixedly provided on the inner wall of the cabinet 1 at the corresponding positions of the holding block 33 and a guide rod 35 is fixedly provided on the inner side of the guide frame 34. The holding block 33 is slidably arranged outside the two guide rods 35 together. The outer ring of the guide rod 35 is located between the top surface of the holding block 33 and the inner wall of the guide frame 34 and is sleeved with a spring member 36.

When in use, the holding block 33 is slid up and down by two guide rods 35 and is set on the inner side of the cabinet 1, and the holding block 33 drives the positioning rod 3 and the clamping rail sleeves 30 at both ends of the positioning rod 3 to slide up and down. When installing the fixed frame 2, the holding block is pulled to slide radially upward along the two guide rods 35. During the sliding process, the elastic reciprocating force of the spring member 36 is overcome and the spring member 36 is in an energy storage state. The holding block drives the positioning rod 3 and the clamping rail sleeves 30 at both ends of the positioning rod 3 to move radially upward. At this time, the fixed frame 2 is installed into the assembly port 10. When the fixed frame 2 reaches the specified installation position, the holding block is released. The spring member 36 releases the stored energy and causes the holding block 33 to retract to the initial position along the guide rod 35. The holding block drives the positioning rod 3 and the clamping rail sleeves 30 at both ends of the positioning rod 3 to move downward. The clamping rail sleeves 30 move downward and are sleeved on the outside of the clamping rail 20 and slide relatively along the clamping rail 20. During the above process, the arc-shaped clamping ribs 31 on the inner side of the clamping rail sleeve 30 enter the arc-shaped clamping grooves 21 on the outer side of the clamping rail 20 and form a limited clamping. The horizontal clamping is formed between the clamping rail sleeve 30 and the clamping rail 20 to complete the installation of the fixed frame 2. When the fixed frame 2 needs to be disassembled, the opposite operation can be performed.

The positioning rod 3 is fixedly connected to the clamping rail sleeve 30 through the fixed cover plates 32 at both ends. When the fixing frame 2 is installed, when the lower end surface of the fixed cover plate 32 abuts against the upper end surface of the clamping rail 20, it means that the clamping rail sleeve has reached the specified clamping position;

The inner edge of the lower end of the clamping rail sleeve 30 has an inclined waist surface, which guides the sleeve fitting between the clamping rail sleeve 30 and the clamping rail 20 to ensure smooth fitting between the clamping rail sleeve 30 and the clamping rail 20;

The clamping rail 20 is a vertical strip structure, and the clamping rail sleeve 30 is a vertical U-shaped structure and forms a sliding area adapted to the clamping rail 20 .

A conducting section 22 is provided at the center of the fixing frame 2, and a dust screen 23 is built into the opening end of the conducting section 22; a plurality of grid plates 24 are arranged from top to bottom at the opening end outside the conducting section 22, and the outer ends of the grid plates 24 are tilted downward.

When in use, the air inside and outside the cabinet 1 is exchanged through the conduction interval 22, and the dust particles mixed in the air entering the cabinet 1 are blocked by setting the dustproof net 23 to achieve a dustproof effect;

The grid plate 24 is provided to prevent external rainwater or other impurities from entering the conduction interval 22 and entering the cabinet 1 through the conduction interval 22 .

A pressing portion 4 extends from the outer peripheral surface of the fixing frame 2 , and a pressing section 40 adapted to the pressing portion 4 extends from the outer opening end of the assembly opening 10 . When the fixing frame 2 is in the installed state, the pressing portion 4 is in close contact with the pressing section 40 .

When in use, the fixing frame 2 is installed by pushing the fixing frame 2 into the assembly opening 10 until the abutting portion 4 on its outer periphery abuts against the abutting interval 40 , thus completing the installation of the fixing frame 2 .
