Description

Technical Field

[0001] This utility model relates to the field of power supply frame technology, specifically a power supply frame with a double sheet metal assembly. Background Technology

[0002] High-frequency switching power supply equipment is placed inside the power supply frame, and the rectangular frame with double sheet metal combination is currently popular in the market.

[0003] The assembly and production of rectangular frame products composed of two sheet metal parts presents numerous challenges. For instance, while these products are assembled using riveting, securing them with rivets through mounting holes, this process is inconvenient. Users must hammer the rivets into place, and once secured, the rivets are difficult to remove. This makes maintenance difficult if one sheet metal part is damaged, necessitating replacement and resulting in waste. Furthermore, during assembly and transportation, the sheet metal parts are prone to deformation at the rear corners due to pressure, significantly increasing the risk of product defects.

Detailed Implementation

[0024] This utility model embodiment provides a power supply frame with a double sheet metal assembly, such as... Figure 1-5 As shown, it includes a front plate 1, a bottom plate 2, a back plate 3, side plates 4, a partition 5, and a connecting plate 6. The lower end of the front plate 1 is fixedly inserted into the bottom plate 2, and the upper end of the front plate 1 is bent backward and fixedly inserted into the back plate 3. The connecting plate 6 is fixedly installed between the bottom plate 2 and the back plate 3, and the side plates 4 are symmetrically fixedly installed on the left and right sides of the front plate 1.

[0025] The middle section of the connecting plate 6 has an arc-shaped curved surface. An elastic rubber block 61 is fixedly embedded on the outer side of the connecting plate 6 at the curved surface. The elastic rubber block 61 is used to contact the ground. The elastic rubber block 61 improves the load-bearing capacity of the bottom rear end of the frame, acts as a buffer, and prevents the corners from deforming under pressure. Setting the connecting plate 6 into an arc shape further improves its load-bearing capacity.

[0026] The top of the connecting plate 6 has a slot 62, and the lower end of the back plate 3 is inserted into the slot 62. After the back plate 3 is inserted into the slot 62, a bolt passes through the back plate 3 and the slot 62, and the back plate 3 and the connecting plate 6 are fixed together by the bolt and nut.

[0027] A support plate 63 is welded to the inner side of the connecting plate 6, and the rear end of the base plate 2 is inserted into the support plate 63.

[0028] A vertical partition 5 is fixedly installed on the top of the base plate 2.

[0029] An extension 11 is connected to the inward side of the front plate 1, and the front plate 1 and the extension 11 are integrally formed. The extension 11 has a through groove 111, and the bottom plate 2 and the back plate 3 both have slots corresponding to the groove 111. When the front plate 1 is attached to the bottom plate 2 and the back plate 3, the slots and the groove 111 form a rectangular groove, and an insert 7 is inserted into the rectangular groove. The end of the insert 7 passes through the side plate 4.

[0030] The front end of the support plate 63 is provided with a protrusion 631, and the support plate 63 and the protrusion 631 are integrally formed.

[0031] Multiple inserts 21 are welded to the top of the base plate 2. The multiple inserts 21 are in pairs and a clamping groove is formed between the two inserts 21 in the same group. The inserts 21 have through holes 211. The front end of the support plate 63 can be inserted into the clamping groove, and the protrusion 631 fits into the hole 211.

[0032] A flange 12 is attached to the top of the inner wall of the front panel 1, and the front panel 1 and the flange 12 are integrally formed. The flange 12 is threadedly connected to the side panel 4 by bolts and nuts, which serves to reinforce the panel.

[0033] It also includes two sets of positioning blocks 8, one set of positioning blocks 8 is welded to the top of the inner wall of the front plate 1, and the other set of positioning blocks 8 is welded to the top of the bottom plate 2. The partition plate 5 is threadedly connected to the positioning blocks 8 by bolts and nuts.

[0034] The aforementioned front plate 1, bottom plate 2, back plate 3, side plate 4, partition plate 5, and connecting plate 6 are made of sheet metal one, which is an aluminum plate. The partition plate 5, support plate 63, and insert plate 21 are made of sheet metal two, which is a galvanized plate.

[0035] In summary, this dual-sheet metal power supply frame consists of a front plate 1, a bottom plate 2, a back plate 3, side plates 4, partitions 5, and a connecting plate 6. The entire frame is divided into multiple components. These components are secured together by slots 62, support plates 63, and protrusions 631, allowing the connecting plate 6 to be inserted and fixed to the bottom plate 2 and back plate 3. Furthermore, the extension 11 engages with the insert 7, forming a pin-like connection between the front plate 1, bottom plate 2, back plate 3, and side plate 4. This achieves the desired fixation, replacing the traditional rivet-driven fixing method and facilitating disassembly, assembly, and parts replacement. Maintenance is also much faster.

[0036] Furthermore, the connecting plate 6 is set in a semi-circular arc shape and is equipped with an elastic rubber block 61. The elastic rubber block 61 is located at the bend of the connecting plate 6. With the help of the elasticity of the elastic rubber block, the bottom edge of the frame can be buffered when subjected to force, so as to avoid the corners from deforming immediately when subjected to force.
