Description

Technical Field

[0001] The utility model relates to a fixing structure, in particular to a ventilation net fixing structure of an AC / DC power supply panel. Background Art

[0002] According to the common power supply, during the AC-DC power conversion process, the operation of the electronic components will generate high temperature. In order to avoid the damage of the electronic components caused by the excessively high internal temperature of the power supply, the industry usually installs heat dissipation fins and a heat dissipation fan inside the power supply. At the same time, at least one opening is also opened on the panel of the power supply, and a ventilation net is assembled on the opening, so that the cold air outside the power supply can be brought into the body through the heat dissipation fan, so as to achieve the heat dissipation effect of the power supply.

[0003] However, the ventilation net is usually fixed to the housing or panel of the power supply by screw locks. Therefore, the industry must drill a plurality of predetermined lock holes in the housing and ventilation net of the power supply and fix them by a plurality of locking pieces. The above fixing structure not only easily destroys the appearance of the power supply, but also makes the installation process more complicated, which is indeed room for improvement.

[0004] Therefore, the inventor of this case has made improvements to the above-mentioned shortcomings and obtained Utility Model Patent No. M421524 in Taiwan, China. The invention mainly has at least two extension parts protruding vertically in the same direction on the inner side of the panel body, and the relative inner sides of the extension parts are respectively extended with a limiting part at a position adjacent to the panel body, and the limiting parts are arranged in parallel with the panel body, and respectively form a reserved gap, and the two ends of the ventilation net are placed in the gaps. Thus, through an external force pressing on the limiting parts, the limiting parts are deformed toward the direction of the panel body, and then the limiting parts fix the ventilation net on the panel body, so that the use of fasteners for locking is eliminated, thereby simplifying the installation process of the ventilation net.

[0005] However, since the ventilation net is composed of a flat metal plate, it lacks flexibility. Therefore, the reserved gap needs to have a larger width to facilitate the installation of the ventilation net. Then, external force is further applied to the limit parts to deform them toward the panel body, thereby fixing the ventilation net on the panel body to prevent the ventilation net from loosening or even falling off. Therefore, this installation structure and method also generates an additional installation process.

[0006] In view of this, the inventor has finally come up with the present utility model based on his long-term research and development experience in the relevant technical field. Utility Model Content

[0008] To achieve the above-mentioned purpose, the utility model provides a power supply panel ventilation net fixing structure, which mainly includes: a panel body, whose longitudinal section is roughly arc-shaped, an extension plate is extended laterally inward from the top and bottom ends of the panel body, and at least one ventilation hole is provided on the panel body, and the extension plates are extended inward at the corresponding positions of the ventilation hole, so that a limiting groove is formed between the limiting flanges and the panel body respectively; at least one ventilation net is arranged on the ventilation hole corresponding to the shape of the ventilation hole, the ventilation net has a plurality of ventilation holes, and the longitudinal section of the ventilation net also forms an arc shape with respect to the panel body, so that the ventilation net has flexibility that can be bent and deformed, so that the ventilation net can be placed in the limiting grooves at its top and bottom ends respectively through its own flexibility, thereby fixing the ventilation net on the panel body.

[0009] Furthermore, the limiting flanges are respectively formed with a guiding inclined surface on both sides of the ends, so that the longitudinal sections of the limiting flanges are all roughly cone-shaped, so that the top and bottom ends of the ventilation net can be placed in the limiting grooves.

[0010] Furthermore, the vent is rectangular.

[0029] See also Figures 1 to 5 As shown, they are respectively an exploded stereogram, another exploded stereogram, a combined stereogram, a front view and a combined cross-sectional view of a preferred embodiment of the utility model, which discloses the ventilation net fixing structure of the power supply panel of the utility model, which mainly includes:

[0030] A panel body 10 is roughly rectangular and its longitudinal section is roughly arc-shaped. Two rectangular ventilation holes 11 are opened on the panel body 10, and the two ends of the panel body 10 are respectively defined as a top end 12 and a bottom end 13, and the inner side surface of the panel body 10 has an extension plate 14 protruding vertically in the same direction at the top end 12 and the bottom end 13. The extension plates 14 all extend inwardly at the corresponding positions of the ventilation holes 11 with a limiting flange 15. The limiting flanges 15 are respectively formed with a guiding inclined surface 151 on both sides of the end, so that the longitudinal sections of the limiting flanges 15 are roughly conical, and a limiting groove 16 is respectively formed between the limiting flanges 15 and the panel body 10.

[0031] Two ventilation nets 20 are arranged on the ventilation opening 11 corresponding to the shape of the ventilation opening 11. The ventilation net 20 has a plurality of ventilation holes 21. The ventilation holes 21 are honeycomb-shaped, and the longitudinal section of the ventilation net 20 also forms an arc shape with respect to the panel body 10. The ventilation net 20 is made of a flexible metal material, so that the ventilation net 20 has flexibility that can be bent and deformed, and through its own flexibility, the top and bottom ends of the ventilation net 20 can be respectively placed in the limiting grooves 16, thereby fixing the ventilation net 20 on the panel body 10.

[0032] In order to further understand the structural features, technical means and expected effects of the present invention, the assembly method and the effects achieved by the present invention are described. It is believed that this will provide a deeper and more specific understanding of the present invention, as described below:

[0033] When the ventilation net 20 is to be assembled on the panel body 10, one only needs to first insert one end of the ventilation net 20 into the limiting groove 16 of the panel body 10, and then apply external force to the ventilation net 20 to bend and deform the ventilation net 20 until the other end of the ventilation net 20 can cross the corresponding limiting flange 15 and be inserted into the limiting groove 16. Since the limiting flanges 15 are respectively formed with a guiding inclined surface 151 on both sides of the end, the top and bottom ends of the ventilation net 20 can be easily inserted into the limiting grooves 16. At this time, when no external force is applied to the ventilation net 20, the top and bottom ends of the ventilation net 20 will be respectively extended into the limiting grooves 16 due to its own flexible restoring force, and tightly attached to the inner wall of the panel body 10 to be fixed, thereby completing the installation of the ventilation net 20.

[0034] Hereinafter, the features of the present invention and the expected effects that can be achieved are described as follows:

[0035] The power supply panel ventilation net fixing structure of the present invention adopts an arc-shaped design for the ventilation net 20, so that the ventilation net 20 has a certain flexibility. Therefore, when the ventilation net 20 is to be installed in the limiting groove 16 formed between the panel body 10 and the limiting flanges 15, it only needs to be pressed by an external force to form a larger bending deformation of the ventilation net 20, so that the ventilation net 20 can be easily placed in the limiting groove 16 of the panel body 10. When the external force disappears, the ventilation net 20 will extend into the limiting groove 16 due to its own flexible restoring force and be tightly attached to the inner side wall of the panel body 10. Therefore, it is not only unnecessary to fix with bolts, simplifying the installation process of the ventilation net 20, but also because the panel body 10 and the ventilation net 20 are both designed in an arc shape, it also has an aesthetic effect.

[0036] However, what is described above is only a preferred embodiment of the present invention. Therefore, all equivalent structural changes made by applying the specification and claims of the present invention should be included in the patent scope of the present invention.
