Description
Technical Field
The utility model relates to the technical field of power distribution cabinets, in particular to a cabinet door sealing structure of a power distribution cabinet.
Background
In order to avoid the influence of moisture, dust, harmful substances or temperature and the electrical industry with higher safety protection requirements, the protection grade is a basic index of electrical elements and equipment and is generally evaluated by the IP protection grade. The power distribution cabinet used in some special areas has higher IP protection level requirements, the traditional sealing process adopts a pressing strip, a sticking strip and a fillet mode to realize the sealing of an electric shell, and has the defects of high cost, easy falling, aging, low protection level and the like.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the existing problems, the utility model provides a cabinet door sealing structure of a power distribution cabinet.
The technical scheme adopted by the utility model for solving the technical problem is as follows: the utility model provides a switch board cabinet door seal structure, includes cabinet door and the cabinet body, the cabinet door lid closes on the cabinet body, the four circumference of opening of the cabinet body is interior bending type to be formed with the sealing, upward the internal bending type of cabinet has triangular seal groove in the sealing, the cabinet door back has semicircular foaming strip all around the coating, foaming strip is located the seal groove, the back butt sealing of cabinet door.
The sealing contact structure is improved to increase the sealing property of the cabinet door, the sealing groove for accommodating the foaming strip is arranged, the cabinet door is directly abutted to the cabinet body, the closing force of the cabinet door is not fully applied to the foaming strip, the extrusion to the foaming strip is reduced, the sealing surface is increased, the sealing effect of the cabinet door is improved, the service life of the foaming strip can be prolonged, and the IP protection grade of the cabinet door is effectively maintained.
According to another embodiment of the utility model, the cabinet further comprises a reinforcing strip formed by bending the edge of the sealing part towards the inside of the cabinet body. Through setting up the enhancement strip, the intensity of reinforcing sealing portion guarantees the abundant contact of foaming strip and seal groove, guarantees sealed effect.
According to another embodiment of the present invention, further comprising attaching a foam strip to the back peripheral edge of the cabinet door, the foam strip abutting the seal. Through setting up the foam strip, reduce the influence of the whole unevenness of sealing and cabinet door, provide simultaneously that first is sealed, improve sealed effect.
According to another embodiment of the present invention, further comprising the angle of the sealing groove is greater than 90 °. Set up great angle, reduce the sealing resistance of cabinet door.
According to another embodiment of the present invention, the foam strip is made of polyurethane. The polyurethane foaming adhesive is selected, so that the foaming strip has good elasticity, large temperature adaptation range and low cost.
The cabinet door has the advantages that the sealing performance of the cabinet door is improved by improving the sealing contact structure, the cabinet door is directly abutted against the cabinet body by arranging the sealing groove for accommodating the foaming strip, so that the closing force of the cabinet door is not fully exerted on the foaming strip, the extrusion to the foaming strip is reduced, meanwhile, the sealing surface is increased, the sealing effect of the cabinet door is improved, the service life of the foaming strip can be prolonged, the IP protection grade of the cabinet door is effectively maintained, the influence of the integral unevenness of the sealing part and the cabinet door is reduced by arranging the foaming strip, the first sealing is provided, and the sealing effect is further improved.
Drawings
The utility model is further illustrated with reference to the following figures and examples.
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is another schematic structural diagram of the present invention.
In the figure, a cabinet door 1, a cabinet body 2, a sealing part 21, a sealing groove 22, a foaming strip 3 and a foaming strip 4 are arranged.
Detailed Description
As shown in fig. 1-2, which are schematic structural diagrams of the present invention, a cabinet door sealing structure of a power distribution cabinet includes a cabinet door 1 and a cabinet body 2, wherein the cabinet door 1 is covered on the cabinet body 2, four sides of an opening of the cabinet body 2 are bent inward to form sealing portions 21, the sealing portions 21 are bent inward to form triangular sealing grooves 22, semicircular foam strips 3 are coated on the periphery of the back of the cabinet door 1, the foam strips 3 are located in the sealing grooves 22, and the back of the cabinet door 1 abuts against the sealing portions 21.
The foaming strip 3 is formed by automatic coating through a sealing glue spreader, and accurate embedding with the sealing groove 22 is guaranteed.
Preferably, the edge of the sealing portion 21 is bent toward the inside of the cabinet to form a reinforcing strip 23.
The sealing groove 22, the reinforcing strip 23 and the cabinet body 2 are integrally formed by bending.
Preferably, a foam strip 4 is attached to the peripheral edge of the back surface of the cabinet door 1, and the foam strip 4 abuts against the sealing portion 21.
Preferably, the angle of the sealing groove 22 is greater than 90 °.
Preferably, the foam strip 3 is made of polyurethane.
The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the utility model as defined in the appended claims.
