Description

Technical Field

[0001] The utility model belongs to the technical field of stable power supply, and in particular relates to a multifunctional stable power supply device. Background Art

[0002] A multifunctional stable power supply provides stable and reliable power output and is widely used in electronic equipment testing, scientific research, industrial automation, and other fields. Its core function is to ensure the stability of output voltage and current, while also offering a variety of additional features to meet the needs of diverse application scenarios. This multifunctional stable power supply utilizes advanced digital control algorithms and precision components to achieve millivolt-level control of output voltage and current fluctuations. It supports a wide input range, adapting to diverse power grid environments, and maintains an output ripple of less than 10mV.

[0003] Existing multifunctional, stable power supplies often generate significant heat during continuous operation due to their high internal power conversion and densely packed circuitry. This heat builds up inside the power supply housing due to poorly designed heat dissipation structures, preventing it from being effectively dissipated to the outside environment. Prolonged high-temperature operation can accelerate the aging of critical components, leading to performance drift and even damage, impacting the stability and lifespan of the power supply.

When the wire moves to the inner wall of the first rubber pad, the first rubber pad can restore the deformation. Therefore, the position of the wire can be fixed by the first rubber pad, thereby realizing the bundling of the wires and preventing the wires from being easily pulled when they are too long.

[0033] The cable fixing assembly 300 includes a cable clamping portion 301 disposed on the upper surface of the power supply 101, a second fixing portion 302 connected to the side surface of the cable clamping portion 301 and connected to the upper surface of the power supply 101, and a guide portion 303 connected to the side surface of the cable clamping portion 301 and connected to the upper surface of the power supply 101.

[0034] The suspension assembly 400 includes a central axis 401 connected to the inner wall of the side panel 102, a hanging plate 402 sleeved on the surface of the central axis 401 and embedded in the inside of the side panel 102, a hanging hole 403 opened on the surface of the hanging plate 402, and a second rubber pad 404 connected to the end of the hanging plate 402 and interference-connected with the inner wall of the side panel 102.

[0035] Preferably, the first fixing portion 202 includes a clamping groove 202 a provided at both ends of the sealing plate 201 and a positioning rubber strip 202 b connected to the inner wall of the opening of the side plate 102 .

[0036] During specific use, when the sealing plate 201 drives the card slot 202a to move to the surface of the rubber strip 202b, the rubber strip 202b is squeezed and deformed. When the sealing plate 201 drives the card slot 202a to move to the inner side of the rubber strip 202b, the position of the sealing plate 201 can be fixed by the rubber strip 202b and the card slot 202a.

[0037] Preferably: the pull ring portion 203 includes a pull ring 203a embedded in the inner wall of the groove of the sealing plate 201, a rotating shaft 203b passing through the interior of the pull ring 203a and connected to the inner wall of the sealing plate 201, and a rubber block 203c connected to the side surface of the pull ring 203a and interference-connected with the groove of the sealing plate 201, the rotating shaft 203b is located on one side of the pull ring 203a, and the rubber block 203c is located on the other side of the pull ring 203a.

[0038] During specific use, the pull ring 203a can rotate on the surface of the rotating shaft 203b when subjected to tension. After the pull ring 203a is rotated out, tension can be applied to the closing plate 201 through the pull ring 203a.

[0039] Preferably, the positioning portion 204 includes a positioning block 204a connected to the inner wall of the opening of the side plate 102 and a positioning groove 204b formed on the surface of the sealing plate 201 and corresponding to the positioning block 204a in one-to-one correspondence and having a size matching that of the positioning block 204a.

[0040] During specific use, the sealing plate 201 can drive the positioning groove 204b to engage with the positioning block 204a, so that the position of the sealing plate 201 can be limited.

[0041] Preferably, the wire clamping portion 301 includes wire clamping blocks 301a provided on the upper and lower surfaces of the power supply 101 and first rubber pads 301b connected to the inner wall of the wire clamping groove of the wire clamping blocks 301a. The diameter of the wire 103 is greater than the distance at the smallest opening of the first rubber pads 301b.

[0042] During specific use, when the wire 103 moves to the opening of the first rubber pad 301b, the first rubber pad 301b is squeezed and deformed. When the wire 103 moves to the inner wall of the first rubber pad 301b, the first rubber pad 301b can recover the deformation through its own elasticity, so that the first rubber pad 301b can fix the position of the wire 103.

[0043] Preferably, the second fixing portion 302 includes a side ear 302a connected to the side surface of the wire clamping block 301a, a fixing hole 302b opened on the surface of the side ear 302a, a fixing bolt 302c passing through the fixing hole 302b, and a threaded hole 302d opened on the surface of the power supply 101 and adapted to the fixing bolt 302c.

[0044] During specific use, when the fixing bolt 302c passes through the interior of the fixing hole 302b and is threadedly connected to the threaded hole 302d, the position of the side ear 302a can be fixed, thereby fixing the position of the wire-holding portion 301.

[0045] Preferably, the guide portion 303 includes guide rails 303a connected to the surface of the power supply 101 and located on both sides of the wire clamping block 301a, and guide grooves 303b opened on both sides of the wire clamping block 301a and adapted to the guide rails 303a.

[0046] During specific use, the wire clamping block 301a can drive the guide groove 303b to slide on the surface of the guide rail 303a, so as to limit the movement direction of the wire clamping block 301a.

[0047] The working principle of the present invention during specific use: When the stable power supply device is in use, when a large amount of heat appears inside the power supply 101 and needs to be dissipated, the pull ring 203a is pulled first. When the pull ring 203a is subjected to tension, it can drive the rubber block 203c to rotate on the surface of the rotating shaft 203b. When the pull ring 203a rotates to the outside of the groove of the sealing plate 201, the pull ring 203a can be pulled to apply tension to the sealing plate 201. When the sealing plate 201 is subjected to tension, it can squeeze the positioning rubber strip 202b through the card slot 202a. The positioning rubber strip 202b can be deformed when squeezed. When the sealing plate 201 drives the card slot 202a to move to the outside of the positioning rubber strip 202b, the sealing plate 201 can be removed from the inner wall of the side panel 102, so that the inner wall of the power supply 101 can be dissipated through the dustproof net 205.

[0048] When the wire clamping part 301 is installed, the wire clamping block 301a first drives the guide groove 303b to slide on the surface of the guide rail 303a. After the wire clamping block 301a drives the fixing hole 302b to be vertically aligned with the fixing bolt 302c through the side ear 302a, the fixing bolt 302c passes through the fixing hole 302b and is threadedly connected to the threaded hole 302d. In this way, the position of the wire clamping part 301 can be fixed. When the wire 103 is too long, it can be driven to move to the opening of the first rubber pad 301b. When the first rubber pad 301b is squeezed, it can be deformed. When the wire 103 moves to the inner wall of the first rubber pad 301b, the first rubber pad 301b can restore its deformation, so that the position of the wire 103 can be fixed by the first rubber pad 301b.

[0049] When the hanging plate 402 is subjected to tension, it can rotate on the surface of the central axis 401. When the hanging plate 402 rotates to the outside of the side plate 102, the power supply component 100 can be hung through the hanging hole 403 on the surface of the hanging plate 402. When there is no need to hang the power supply component 100, the hanging plate 402 can be driven to move toward the inner wall of the side plate 102. When the hanging plate 402 drives the second rubber pad 404 to move to the inner wall of the side plate 102, it is squeezed and deformed. When the hanging plate 402 drives the second rubber pad 404 to move to the inner wall of the side plate 102, the position of the hanging plate 402 can be fixed by the friction between the second rubber pad 404 and the inner wall of the side plate 102.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
