Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinet equipment, in particular to a waterproof structure of a power distribution cabinet. Background Art

[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box) and metering cabinet (box). It is the final equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in occasions with relatively dispersed loads and fewer circuits; the motor control center is used in occasions with concentrated loads and more circuits. They distribute the electrical energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] In the prior art, the design of the distribution cabinet is generally to stick a sealing strip on the cabinet door, and the sealing strip and the cabinet body are in contact with each other to achieve a sealing effect. Although this structural design can achieve a sealing effect, the environment of the outdoor distribution cabinet is relatively harsh, that is, the temperature difference between day and night will gradually cause the glue on the sealing strip to gradually lose its viscosity. As a result, after the distribution cabinet has been used for a period of time, the sealing rubber ring loses its viscosity and falls off the cabinet door, and the sealing strip cannot achieve the purpose of waterproofing.

The rubber strip is connected end to end to form a rectangular structure, and a fixing piece is arranged corresponding to the rubber strip, and the fixing piece can fix the rubber strip;

[0006] The fixing part includes a first clamp and a second clamp which are hingedly arranged. Both the first clamp and the second clamp are concave structures. The ends of the first clamp and the second clamp are connected by a connecting component. The connecting component can fix the two clamps together to form a rectangular ring structure.

[0007] The connecting assembly includes connecting blocks arranged at the ends of the first clamp and the second clamp, and the connecting blocks are arranged at one end of the first clamp and the second clamp away from the hinge. Threaded holes are arranged on the two connecting blocks, and bolts are arranged corresponding to the two threaded holes; that is, the bolts can be inserted into the two threaded holes to connect the two connecting blocks together.

[0008] A force-applying member is provided at the end of the bolt, that is, the force-applying member facilitates the bolt to rotate.

[0023] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the following will be combined with the appended drawings of the embodiment of the utility model. Figure 1-5 , the technical scheme of the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0024] like Figure 1-5 As shown: This embodiment provides a waterproof structure of a power distribution cabinet, including a cabinet body 100 and a cabinet door 101 hingedly arranged on the cabinet body 100, the cabinet body 100 includes a resistance ring 102, and a rubber strip 103 is provided on the cabinet door 101 corresponding to the resistance ring 102, the rubber strip 103 is connected end to end to form a rectangular structure, and a fixing piece 200 is provided corresponding to the rubber strip 103;

[0025] The cabinet door 101 can rotate at the entrance of the cabinet body 100. The cabinet body 100 includes a resistance ring 102. A rubber strip 103 is also provided corresponding to the resistance ring 102. The rubber strip 103 can be connected end to end to form a rectangular structure and placed on the cabinet door 101. A fixing part 200 is also provided corresponding to the rubber strip 103. The fixing part 200 can fix the rubber strip 103 on the cabinet door 101, so that the rubber strip 103 will not fall off the cabinet door 101.

[0026] The fixing part 200 includes a first clamp 201 and a second clamp 202 which are hingedly arranged. Both the first clamp 201 and the second clamp 202 are concave structures. The ends of the first clamp 201 and the second clamp 202 are hingedly connected together. The ends of the first clamp 201 and the second clamp 202 away from the hinge are connected through a connecting component; the connecting component can connect the ends of the first clamp 201 and the second clamp 202 away from the hinge, that is, by installing the fixing part 200 on the outside of the rubber strip 103, the rubber strip 103 can be fixed on the cabinet door 101.

[0027] After the rubber strip 103 is fixed to the cabinet door 101 by the fixing member 200 and the cabinet door 101 is closed, the rubber strip 103 can contact the contact ring 102, so that the rubber strip 103 and the contact ring 102 can seal the power distribution cabinet, and the rubber strip 103 will not fall off the cabinet door 101;

[0028] Connect components such as Figure 3 As shown,

[0029] The connecting component includes a connecting block 203 arranged at the end of the first clamp 201 and the second clamp 202 away from the hinge, and the two connecting blocks 203 are both provided with threaded holes 204, and bolts 205 are provided corresponding to the two threaded holes 204; the bolts 205 can be inserted into the two threaded holes 204, that is, the two connecting blocks 203 can be connected together by inserting the bolts 205 into the two threaded holes 204, so that the first clamp 201 and the second clamp 202 can be connected together to form a rectangular frame structure, and the first clamp 201 and the second clamp 202 can fix the rubber strip 103 on the cabinet door 101.

[0030] A force-applying member 206 is disposed at the end of the bolt 205 ; the force-applying member 206 is configured as a plate-shaped structure, that is, the bolt 205 can be easily rotated by means of the force-applying member 206 .

[0031] The cross section of the rubber strip 103 is a concave structure; the fixing member 200 is installed in the concave structure of the rubber strip 103, that is, the concave structure can limit the fixing member 200, thereby preventing the fixing member 200 from falling off from the cabinet door 101 and the rubber strip 103.

[0032] The guide ring groove 104 is as follows Figure 5 As shown,

[0033] A guide ring groove 104 is provided on the resistance ring 102, and the cross-section of the guide ring groove 104 is a V-shaped structure; that is, rainwater falling onto the resistance ring 102 through the gap between the cabinet door 101 and the cabinet body 100 can flow downward along the guide ring groove 104, thereby preventing the rainwater on the resistance ring 102 from entering the cabinet body 100 at the moment the cabinet door 101 is opened.

[0034] A rain shelter 105 is also provided on the top of the cabinet body 100 ; the rain shelter 105 can block a large amount of rainwater, thereby greatly reducing the rainwater that falls onto the abutment ring 102 through the gap between the cabinet door 101 and the cabinet body 100 .

[0035] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0036] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
