Description
Technical Field
[0001] The utility model belongs to the technical field of switching power supplies, and particularly relates to a switching power supply with wiring protection. Background Art
[0002] A switching power supply is a high-frequency power conversion device, also known as a switched-mode power supply and a switching converter. When in use, it can convert a voltage of one level into the voltage or current required by the user through different forms of architectures, and is widely used in fields such as industrial automation control, LED lighting, communication equipment, and power equipment.
[0003] However, during the actual use of the switching power supply, when the external power transmission line is connected to the switching power supply, it is mostly directly inserted into the switching power supply. The connection structure between the power transmission line and the switch is relatively thin, lacking protection measures. When subjected to bending and extrusion, the wiring part is prone to breakage, which is not convenient for protecting the wiring part. There is a need for a switching power supply with wiring protection. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a switching power supply with wiring protection. Its advantages are as follows: it can reduce the breakage of the wiring part and is convenient for protecting the wiring part.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A switching power supply with wiring protection includes a switching power supply housing. A plurality of circuits are fixedly connected inside the switching power supply housing. One end of the switching power supply housing is provided with a switch. Adjusting ports are opened on both sides of the outer wall at the top of the switching power supply housing. A fixing mechanism is arranged inside the adjusting ports. An adjusting mechanism is arranged inside the switching power supply housing. A dust-proof mechanism is arranged at the bottom of the outer wall at one end of the switching power supply housing;
[0007] The fixing mechanism includes a first clamping ring and a second clamping ring. The opposite surfaces of the first clamping ring and the second clamping ring are both arc-shaped structures. Both sides of the first clamping ring and the second clamping ring form a sliding fit with the inner wall of the adjustment opening. A number of uniformly distributed fixing openings are provided on both sides of one end of the first clamping ring and the second clamping ring. The inner wall of the fixing opening is threadedly connected with a fixing rod. By rotating the rotating block in the rotating groove, the threaded rod can be rotated. The rotation of the threaded rod can apply force to the adjusting block. At this time, the adjusting block can slide in the inner wall of the connecting groove. The movement of the adjusting block can adjust the positions of the first clamping ring and the second clamping ring. The appropriate position can be selected according to the position where the switch power supply housing is embedded or protruded on the wall. After the positions of the first clamping ring and the second clamping ring are adjusted, the wire is located between the first clamping ring and the second clamping ring. Rotating the fixing rod into the fixing opening can make the first clamping ring and the second clamping ring approach each other. The limit between the adjusting rod and the inner wall of the adjusting groove can prevent the first clamping ring and the second clamping ring from tilting. When the wire needs to be bent or slightly stretched, the rotation of the rotating shaft in the inner wall of the rotating groove can also protect the wire. After the installation is completed, the dust-proof plate is pulled out. At this time, the dust falling into the switch power supply housing can fall to the bottom of the dust-proof plate. Then, the dust-proof plate is inserted into the installation groove. Therefore, the breakage at the wiring part can be reduced, and it is convenient to protect the wiring part.
[0008] Rotating grooves are provided at the tops of the inner walls of the opposite surfaces of the first clamping ring and the second clamping ring. A same rotating shaft is rotatably connected between the inner walls at both ends of the rotating groove through a bearing. The setting of the rotating shaft can rotate in the inner wall of the rotating groove. When the wire bends and slides, the rotating shaft will rotate, which can prevent the wire from being scratched and damaged by the edge of the clamping ring.
[0009] The adjusting mechanism includes an adjusting block arranged in the switch power supply housing. An adjusting groove is provided on one side of the adjusting block. Both ends of the inner wall of the adjusting groove are slidably connected with adjusting rods. The two adjusting rods on the same side are fixedly connected between the first clamping ring and the second clamping ring. The setting of the adjusting rods can slide in the inner wall of the adjusting groove, which can change the distance between the two clamping rings and can tighten or loosen the wire.
[0010] The adjusting rod is in a T-shaped structure and is in contact with the inner wall of the adjusting groove. The T-shaped design can form a limit between the adjusting rod and the inner wall of the adjusting groove, which can prevent the adjusting rod from tilting, and thus prevent the clamping ring from tilting.
[0011] Both ends of the switch power supply housing are provided with connecting rods, which are fixedly connected between the inner walls of the switch power supply housing. A connecting groove is formed on one side of the connecting rod, and a sliding fit is formed between the inner wall of the connecting groove and the adjusting block. The setting of the connecting rod can position the adjusting block, and the adjusting block can slide in the inner wall of the connecting groove. At this time, the position of the clamping ring can be adjusted, the skew of the circuit can be reduced, and the circuit can be protected.
[0012] One end inner wall of the connecting rod is rotatably connected with a threaded rod through a bearing, and the threaded rod is threadedly connected with the adjusting block. One end of the threaded rod is fixedly connected with a rotating block. The setting of the rotating block can make the threaded rod rotate when rotating. The rotation of the threaded rod can apply force to the adjusting block, and the adjusting block can slide in the inner wall of the connecting groove.
[0013] Both sides of one end outer wall of the switch power supply housing are provided with rotating grooves, and the rotating block is located in the rotating grooves. The setting of the rotating grooves can accommodate the rotating block and prevent the rotating block from protruding outside the switch power supply housing to ensure the overall beauty of the device.
[0014] The dust blocking mechanism includes a dust blocking plate. An installation groove that forms a sliding fit with the dust blocking plate is provided at the bottom of one end outer wall of the switch power supply housing. The setting of the dust blocking plate can collect the falling dust. After the installation is completed, the dust blocking plate can be pulled out to handle the dust, so that the dust falls below the dust blocking plate.
[0015] The beneficial effects of the present utility model are as follows:
[0016] 1. For the switch power supply with wiring protection, by rotating the rotating block in the rotating groove, the threaded rod can be rotated. The appropriate position can be selected according to the position where the switch power supply housing is embedded or protruded on the wall. After the positions of the first clamping ring and the second clamping ring are adjusted, the limit between the adjusting rod and the inner wall of the adjusting groove can prevent the first clamping ring and the second clamping ring from tilting. When the circuit needs to be bent or slightly stretched, the rotation of the rotating shaft in the inner wall of the rotating groove can also protect the circuit. Therefore, the breakage at the wiring can be reduced, and it is convenient to protect the wiring.
[0017] 2. For the switch power supply with wiring protection, by the adjusting rod being able to slide in the inner wall of the adjusting groove, the distance between the two clamping rings can be changed, and the circuit can be tightened or loosened. The T-shaped structure design can form a limit between the adjusting rod and the inner wall of the adjusting groove, preventing the adjusting rod from skewing, and thus preventing the clamping ring from skewing.
[0018] 3. The switching power supply with wiring protection can rotate the threaded rod when the rotating block rotates. The rotation of the threaded rod can apply force to the adjusting block, and the adjusting block can slide on the inner wall of the connecting groove. The rotating block can be received through the rotating groove, preventing the rotating block from protruding outside the housing of the switching power supply to ensure the overall aesthetics of the device.

The dust-proof mechanism includes a dust-proof plate 18. An installation groove 17 that forms a sliding fit with the dust-proof plate 18 is provided at the bottom of the outer wall at one end of the switching power supply housing 1. The falling dust can be collected by the dust-proof plate 18. After the installation is completed, the dust-proof plate 18 can be pulled out to handle the dust, so that the dust falls below the dust-proof plate 18.
[0030] Referring to Figure 1 , Figure 3 , Figure 4 and Figure 5, the adjusting mechanism includes an adjusting block 7 arranged in the switch power supply housing 1. An adjusting groove 8 is formed on one side of the adjusting block 7. Both ends of the inner wall of the adjusting groove 8 are slidably connected with adjusting rods 9.

The movement of the adjusting block 7 can adjust the positions of the first clamping ring 3 and the second clamping ring 4. The appropriate positions can be selected according to the position of the switch power supply housing 1 embedded or protruding on the wall. After the positions of the first clamping ring 3 and the second clamping ring 4 are adjusted, the wire is located between the first clamping ring 3 and the second clamping ring 4. Rotate the fixing rod 6 into the fixing port 5, and the first clamping ring 3 and the second clamping ring 4 can be made to approach each other. The limit between the adjusting rod 9 and the inner wall of the adjusting groove 8 can prevent the inclination between the first clamping ring 3 and the second clamping ring 4. When the wire needs to be bent or slightly stretched, the rotation of the rotating shaft 16 in the inner wall of the rotating groove 15 can also protect the wire. After the installation is completed, pull out the dust-proof plate 18. At this time, the dust falling into the switch power supply housing 1 can fall to the bottom of the dust-proof plate 18, and then insert the dust-proof plate 18 into the installation groove 17. Therefore, the breakage at the wiring part can be reduced, and it is convenient to protect the wiring part.
