[0002] The power supply housing disclosed in CN204652828U includes a base plate and a cover plate. The cover plate forms a receiving space for receiving the power supply. A first bending through hole is provided at the connection between the cover plate and the base plate, and a second bending through hole is provided at the top of the cover plate.

[0003] Its first bend through hole and the second bend through hole form an airflow channel that runs through the inside of the power supply casing, thereby achieving a good heat dissipation effect.

[0004] However, when maintenance of the power supply inside the casing is required, the casing needs to be removed. The disassembly and assembly of the casing base requires tools and is a complicated process, which affects maintenance efficiency. Furthermore, the lack of sealing at the connection points allows dust to enter, affecting the lifespan of the internal power supply. This solution is not efficient for casing installation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a mounting base for a power supply housing, which solves the problem that when maintenance of the power supply inside the housing is required, the housing needs to be removed. However, the disassembly and assembly of the housing base requires tools and involves complex procedures, affecting maintenance efficiency. Furthermore, the lack of sealing at the connection points allows dust to enter, affecting the service life of the internal power supply.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mounting base for a power supply housing, comprising a base plate, wherein A fixing rods are provided on both sides of the top of the base plate and a square positioning frame is provided in the middle, insert plates are provided on the four sides of the top of the square positioning frame, and elastic silicone sheets are inclinedly provided on both sides of the top of the insert plates, a housing is sleeved on the surface of the square positioning frame, and a slot for inserting the insert plates and elastic silicone sheets is opened at the bottom of the inner wall of the housing, B fixing rods are provided on both sides of the housing, and sleeves are installed at the bottom of both ends of the housing; a fixing hole is opened in the inner wall of the sleeve and a spring and an inner rod are provided inside, a trapezoidal block with an inclined side matching the A conical cap is provided at one end of the inner rod, a circular block is provided at the top of the A fixing rod and a central rod and an A conical cap are fixed at the top of the block, and a B conical cap is slidably connected to the surface of the central rod, and the A conical cap and the B conical cap are arranged symmetrically and oppositely.

[0007] In one specific embodiment, the elastic silicone sheet is inclined downwards at an angle, and its edge forms an interference seal with the inner wall of the outer casing slot.

[0008] In one specific embodiment, the fixing hole in the inner wall of the sleeve is a rectangular through hole, and the spring is sleeved on the outside of the inner rod with its two ends abutting against the inner wall of the sleeve and the trapezoidal block, respectively.

[0009] In one specific embodiment, the inclination angles of the hypotenuses of the A-conical cap and the B-conical cap are the same as and opposite in direction to the hypotenuse angle of the trapezoidal block.

[0010] In a specific embodiment, the fixing holes on the inner sidewall of the sleeve are symmetrically distributed at equal intervals along the axial direction, and the spacing between them is adapted to the travel distance when the outer shell is installed.

[0011] In one specific embodiment, a rubber buffer layer is provided between the square positioning frame and the base plate, and heat dissipation holes are provided on the side of the outer shell.

[0012] Compared with the prior art, the present invention provides a mounting base for a power supply housing, which has the following advantages:

[0013] In the technical solution disclosed in this utility model, the elastic silicone sheets inclined on both sides of the top of the plug plate and the interference contact design with the outer shell slot form a multi-seal structure, which solves the problem of dust easily seeping into the connection of the traditional power supply shell. During installation, the elastic silicone sheets are deformed by pressure to fill the gap, improving the dustproof and waterproof performance. Through the design of the trapezoidal block driven by the spring inside the sleeve and the inclined surfaces of the A cone cap and B cone cap which are symmetrically arranged in opposite directions, the trapezoidal block is squeezed and retracted by the A cone cap during installation. After it is in place, the spring pushes the trapezoidal block to pop out and lock. During disassembly, the outer shell is pulled out in the opposite direction to trigger the B cone cap to move upward and release the trapezoidal block, realizing tool-free quick disassembly and assembly, and improving maintenance efficiency.

[0020] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] Figures 1-4 In one embodiment of this utility model, a mounting base for a power supply housing includes a base plate 1. The base plate 1 has A fixing rods 2 on both sides of its top and a square positioning frame 3 in the middle. The square positioning frame 3 has insert plates 4 on its four sides. The insert plates 4 have elastic silicone sheets 5 on their top sides. The square positioning frame 3 is fitted with a housing 6, and the bottom of the inner wall of the housing 6 has slots for inserting into the insert plates 4 and the elastic silicone sheets 5. The housing 6 has B fixing rods 7 on both sides and sleeves 12 installed at the bottom of both ends.

[0022] The specific problem addressed in this embodiment is that when maintenance of the power supply inside the casing is required, the casing needs to be removed. However, disassembling and assembling the casing base requires tools, is complex, and affects maintenance efficiency. Furthermore, the lack of sealing at the connection points allows dust to enter, affecting the lifespan of the internal power supply. This invention solves the problem of dust easily seeping into the connection points of traditional power supply casings by using an interference fit design between the elastic silicone sheets 5 inclined on both sides of the top of the insert plate 4 and the slot of the casing 6. During installation, the elastic silicone sheets 5 deform under pressure to fill the gaps, improving dust and water resistance. The trapezoidal block 15 driven by the spring 13 inside the sleeve 12, in conjunction with the inclined surfaces of the symmetrically arranged conical caps 10 and 11, allows the trapezoidal block 15 to retract under the pressure of the conical cap 10 during installation. Once in place, the spring 13 pushes the trapezoidal block 15 out and locks it in place. During disassembly, pulling out the casing 6 in the opposite direction triggers the upward movement of the conical cap 11 to release the trapezoidal block 15, achieving tool-free quick disassembly and assembly, thus improving maintenance efficiency.

[0023] The inner wall of the sleeve 12 has a fixing hole and a spring 13 and an inner rod 14 are installed inside. One end of the inner rod 14 is provided with a trapezoidal block 15 with an inclined side that matches the A-cone cap 10. The top of the A fixing rod 2 is provided with a circular block 8, and a central rod 9 and the A-cone cap 10 are fixed on its top. The surface of the central rod 9 is slidably connected to the B-cone cap 11. The A-cone cap 10 and the B-cone cap 11 are arranged symmetrically and oppositely. In this specific embodiment, during installation, the slot of the outer shell 6 is aligned with the insert plate 4 and the elastic silicone sheet 5 and pressed down. The elastic silicone sheet 5 is deformed under pressure and fills the gap to form a seal. At the same time, the sleeve 12 is aligned with the central rod 9 of the circular block 8 and inserted. The A-cone cap 10 squeezes the inclined surface of the trapezoidal block 15 to make it shrink inward until the sleeve 12 is in place. Then the spring 13 pushes the trapezoidal block 15 to pop out and lock it below the A-cone cap 10. During disassembly, the outer shell 6 is pulled out in the opposite direction. The B-cone cap 11 moves upward and separates from the trapezoidal block 15. The spring 13 is released and the sleeve 12 is disengaged. The elastic silicone sheet 5 is sealed to the slot for dust and water protection, while the sleeve 12 and the conical cap work together to achieve tool-free disassembly and assembly, improving maintenance efficiency.

[0024] In this specific embodiment, the elastic silicone sheet 5 is inclined downward at an angle, and its edge forms an interference seal contact with the inner wall of the slot of the outer shell 6;

[0025] The elastic silicone sheet 5 is tilted downwards. When it is inserted into the slot of the outer shell 6, its edge and the inner wall of the slot are squeezed and deformed to form a continuous sealing strip. The tilt angle ensures that the silicone rebound force is evenly distributed. The interference seal effectively prevents external dust and liquid from seeping in and extends the service life of the power supply.

[0026] In this specific embodiment, the fixing hole on the inner wall of the sleeve 12 is a rectangular through hole, and the spring 13 is sleeved on the outside of the inner rod 14 with its two ends abutting against the inner wall of the sleeve 12 and the trapezoidal block 15 respectively.

[0027] The rectangular through hole inside the sleeve 12 constrains the linear movement of the inner rod 14. The spring 13 is sleeved on the outside of the inner rod 14 to provide axial elastic force, which pushes the trapezoidal block 15 to slide along the inclined plane to lock or unlock. The rectangular through hole and the spring 13 cooperate to ensure the movement stability of the trapezoidal block 15 and reduce the risk of jamming.

[0028] In this specific embodiment, the inclination angles of the hypotenuses of the A-conical cap 10 and the B-conical cap 11 are the same as and opposite in direction to the hypotenuse angle of the trapezoidal block 15;

[0029] The hypotenuses of cone cap 10 (A) and cone cap 11 (B) are opposite to the hypotenuses of trapezoidal block 15. When sleeve 12 is inserted, the hypotenuse of cone cap 10 (A) squeezes trapezoidal block 15 to retract. When disassembling, the hypotenuse of cone cap 11 (B) guides trapezoidal block 15 to disengage. The reverse slope design optimizes the locking force transmission path, ensuring a smooth and reliable disassembly and assembly process.

[0030] In this specific embodiment, the fixing holes on the inner sidewall of the sleeve 12 are symmetrically distributed at equal intervals along the axial direction, and the spacing between them is adapted to the travel distance when the outer shell 6 is installed.

[0031] Two sets of symmetrical fixing holes are distributed equidistantly along the axial direction on the inner side wall of the sleeve 12 to match the installation stroke of the outer shell 6, ensuring that the trapezoidal block 15 is accurately locked in the preset position. The equidistant distribution of fixing holes improves the positioning accuracy of the sleeve 12 and the center rod 9, preventing misalignment and loosening.

[0032] In this specific embodiment, a rubber buffer layer is provided between the square positioning frame 3 and the base plate 1, and heat dissipation holes are provided on the side of the outer shell 6.

[0033] The rubber buffer layer between the square positioning frame 3 and the base plate 1 absorbs the vibration and impact of the outer shell 6. The heat dissipation holes on the side of the outer shell 6 promote internal air circulation and heat dissipation. The synergistic design of buffering and heat dissipation reduces the operating temperature of the power supply and mechanical losses, thereby enhancing the reliability of the equipment.

[0034] Working principle: During installation, the slot of the outer shell 6 is inserted into the insert plate 4, and the interference seal of the elastic silicone sheet 5 blocks dust. At the same time, when the sleeve 12 is inserted into the center rod 9, the inclined surface of the A conical cap 10 presses the trapezoidal block 15 to compress the spring 13 and retracts. After it is in place, the spring 13 pushes the trapezoidal block 15 out and locks it under the A conical cap 10. During disassembly, the outer shell 6 is pulled out in the opposite direction, causing the B conical cap 11 to move upward and release the trapezoidal block 15. The inclined surface of the A conical cap 10 guides the trapezoidal block 15 to disengage from the sleeve 12. The rubber buffer layer of the square positioning frame 3 absorbs vibration, and the heat dissipation holes of the outer shell 6 promote airflow circulation, realizing the coordinated operation of sealing and dust prevention, quick disassembly and assembly, and shock absorption and heat dissipation.

The power supply is also common knowledge in the field.
