Description

Technical Field

[0001] The utility model relates to the technical field of power supply protection, in particular to a power supply protection device for electronic engineering. Background Art

[0002] According to the patent document with the publication number CN 221633187 U, the driving motor drives the bidirectional threaded rod to move the mounting block, thereby driving the fixed baffle to clamp and fix the power supply body, and then the protective baffle protects the power supply body through the cooperation between the telescopic spring and the telescopic rod, and the strip heat dissipation holes cooperate with each other to allow the power supply body to dissipate heat;

[0003] When fixing the power supply for distribution, the patent document does not clamp the power supply with too much force because the overall structure of the power supply cannot be squeezed with too much force. However, there is no corresponding support structure on the top of the power supply. Therefore, if the power supply for distribution is impacted in the up and down directions, the power supply may slide up and down between the fixed baffles, which may cause the top and bottom of the power supply to collide. In addition, a certain amount of heat will be generated during the use of the power supply for distribution, which will hinder the circulation of air through the strip-shaped heat dissipation holes. In addition, since the fixed baffles are attached to the outside of the power supply for distribution, the contact between the outside of the power supply for distribution and the air will be reduced to a certain extent, which will affect the heat dissipation process of the entire power supply for distribution. In addition, when the power supply for distribution is not in use, since the strip-shaped heat dissipation holes are always in an open state, if the air at the location where the power supply for distribution is placed is relatively humid, the power supply may be corroded.

[0028] The utility model is further described below in conjunction with the accompanying drawings:

[0029] like Figure 1-Figure 8 As shown, a power supply protection device for electronic engineering includes a power distribution protection mechanism 2, and a power distribution clamping mechanism 1 for supporting the top of the power supply is provided on the upper side of the power distribution protection mechanism 2.

[0030] In this embodiment: the power distribution protection mechanism 2 includes a power distribution frame 21, and a hollow heat dissipation square hole is provided on each of the four sides of the power distribution frame 21, and a plurality of fire-proof heat dissipation frames 22 are rotatably connected in each heat dissipation square hole, and each heat dissipation square hole is provided with a limit hole 211 at the upper and lower ends of the fire-proof heat dissipation frame 22, and a semi-spiral groove 221 is provided at the lower end of the fire-proof heat dissipation frame 22 at the limit hole 211, a bracket 25 is provided on the top of the power distribution frame 21, and a power distribution station 23 is provided at the bottom of the power distribution frame 21, and a plurality of flip bosses 231 are fixed on the four sides of the outside of the power distribution station 23, the bracket 25 is connected to the four corners of the power distribution station 23 by four support rods 24, and a damper 26 for reducing impact force is fixed at the bottom of the power distribution station 23, and a slide groove 211 is provided on the inner side of the power distribution frame 21, which is connected to the limit hole 211. 2, each flip boss 231 passes through the slide groove 212 and is inserted into the corresponding semi-spiral groove 221, the distribution station 23 is provided with four guide grooves 5 distributed around the damper 26 as the center, and the guide groove 5 is provided with a distribution fixing mechanism 3 for clamping the side of the power supply, the four sides of the bracket 25 are provided with movable holes 4, and the inner side of the upper end of the distribution frame 21 is provided with a lock hole 6 corresponding to the movable hole 4, and the distribution station 23 is pushed by the damper 26 to support the power supply. When the distribution station 23 moves upward, it drives the flip boss 231 to slide upward along the slide groove 212, and at the same time, the end of the flip boss 231 moves from the lower end of the semi-spiral groove 221 to its upper end, and then the fireproof heat dissipation frame 22 is rotated 90 degrees in the limiting hole 211, and then multiple fireproof heat dissipation frames 22 are synchronized to no longer close the heat dissipation square hole.

[0031] In this embodiment: the distribution voltage tightening mechanism 1 includes a distribution guard plate 11, and four distribution lock tongues 12 distributed in a ring are slidably connected to the top of the distribution guard plate 11. A distribution handle 13 is slidably connected to the center of the distribution guard plate 11. The distribution handle 13 passes through one end of the distribution guard plate 11 and is fixed with a distribution support plate 14. A push spring 15 is provided between the distribution support plate 14 and the distribution guard plate 11. An L-shaped groove is provided on the top of the distribution guard plate 11 for the end of the distribution lock tongue 12 to be inserted into the lock hole 6 through the movable hole 4. By moving the four distribution lock tongues 12 to gather together, The end of the distribution lock tongue 12 is pulled out from the lock hole 6 of the distribution frame 21, and then the bracket 25 is detached from the distribution frame 21. At this time, the distribution station 23 is pushed by the damper 26 to allow the support rod 24 to push the bracket 25 to move upward. As the distribution lock tongue 12 continues to be moved to allow the end to be detached from the movable hole 4 of the bracket 25, the distribution guard plate 11 can be taken out from the inside of the bracket 25, so that the power supply can be placed on the top of the distribution station 23, and the push spring 15 is used to push the distribution support plate 14 to press on the top of the power supply, so as to press and fix the power supply.

[0032] In this embodiment: the power distribution fixing mechanism 3 includes a power supply clamping frame 31, the upper end of the power supply clamping frame 31 passes through the guide groove 5 and is located on the upper side of the distribution station 23, and a C-shaped spring bar 32 is fixed to the lower end of the power supply clamping frame 31. Both ends of the spring bar 32 away from the power supply clamping frame 31 are fixed to the side positions inside the power distribution frame 21. The spring bar 32 is used to push the power supply clamping frame 31 to fit the outside of the power supply, thereby clamping and fixing the power supply on the distribution station 23.

[0033] Working principle: When in use, first move the four power distribution lock tongues 12 on the top of the power distribution guard plate 11 to move them in the four L-shaped grooves, so as to pull the ends of the power distribution lock tongues 12 out of the movable hole 4 and the lock hole 6 respectively, and then the power distribution guard plate 11 can be taken out from the inner side of the bracket 25;

[0034] Then, the power supply to be protected is placed from the top of the bracket 25, and the four power supply clamping frames 31 are moved away from each other along the four guide grooves 5, and then the power supply is placed on the top of the distribution station 23. At this time, under the support of the damper 26, the distribution station 23 will not drop after the power supply is placed, and then the elastic force of the four spring bars 32 is used to push the corresponding power supply clamping frames 31 to move to the side of the power supply, and then the four power supply clamping frames 31 are respectively attached to the four sides of the power supply, so as to complete the clamping and fixing of the outer periphery of the power supply;

[0035] Then put the power distribution guard plate 11 into the inner side of the bracket 25, and reinsert the four power distribution lock tongues 12 into the corresponding movable holes 4, and then the power distribution guard plate 11 is fixed. At the same time, the push spring 15 at the bottom of the power distribution guard plate 11 pushes the power distribution support plate 14 to press on the top of the power supply, and then the top, bottom and surrounding of the power supply are limitedly supported by the four power supply clamping frames 31, the power distribution station 23 and the power distribution support plate 14 to prevent it from shaking inside the power distribution frame 21;

[0036] like Figure 1 As shown, during the use of the power supply, the bracket 25 is higher than the top of the power distribution frame 21. At this time, the fireproof heat dissipation racks 22 on the outside of the power distribution frame 21 are all opened outward, the periphery of the power supply is heated and the air around it is heated up, and the heated air will flow out from the bracket 25 at the upper end of the power distribution frame 21. As the hot air flows out, cold air will flow from between the multiple fireproof heat dissipation racks 22 to the periphery of the power supply, and then eddy currents will be formed on the outside of the power supply to accelerate heat dissipation;

[0037] When the power supply is no longer in use, the distribution guard plate 11 is pressed downward. At this time, the distribution guard plate 11 pushes the bracket 25 to move into the distribution frame 21 through the distribution lock tongue 12. At this time, the four support rods 24 at the bottom of the bracket 25 push the distribution station 23 to move downward synchronously. When the distribution station 23 moves downward, the flip boss 231 will move from the upper end of the slide groove 212 to its lower end, and the end of the flip boss 231 will also move from the upper end of the semi-spiral groove 221 of the fireproof heat dissipation frame 22 to the lower end. As the flip boss 231 moves downward, the fireproof heat dissipation frame 22 will flip under the cooperation of the semi-spiral groove 221 and the flip boss 231, and then multiple fireproof heat dissipation frames 22 will close the heat dissipation square holes of the distribution frame 21, thereby completing the closed protection of the power supply.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
