Description

Technical Field

[0001] This utility model relates to the field of drive power supply technology, and in particular to a constant current drive power supply with stable connection. Background Technology

[0002] In existing drive power supply technology, traditional drive power supplies are typically fixed with screws or nuts. When the drive power supply itself malfunctions and cannot work, this fixing method makes the disassembly process extremely cumbersome, making it difficult for operators to quickly open the drive power supply and thus unable to promptly understand the internal situation. This results in operators spending a significant amount of time opening the equipment to identify the parts that need repair or replacement, not only delaying the repair progress but also potentially causing economic losses due to prolonged equipment downtime.

[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: because the traditional drive power supply body is fixed with screws or nuts, disassembly is cumbersome. When the drive power supply body is not working, it is difficult to open the drive power supply body, and the internal condition is unknown. This causes the staff to waste a lot of time to open it in order to determine where to repair or replace parts, resulting in certain economic losses. Therefore, to address the above problems, a stable constant current drive power supply is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, which is that the traditional drive power supply body is fixed with screws or nuts, making disassembly cumbersome. When the drive power supply body is not working, it is difficult to open the drive power supply body, making it difficult to know the internal condition. This causes workers to waste a lot of time to open it to determine where to repair or replace parts, resulting in certain economic losses. Therefore, this utility model proposes a stable constant current drive power supply.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a stable constant current driving power supply, comprising a driving power supply body, a rotating groove on the surface of the driving power supply body, a switching device on the inner wall of the rotating groove, the switching device comprising a round rod, the round rod being fixedly connected to the inner wall of the rotating groove of the driving power supply body, an L-shaped cover plate being rotatably connected to the arc surface of the round rod, a trapezoidal block being fixedly connected to the surface of the L-shaped cover plate, a placement groove being fixedly connected to the surface of the driving power supply body, a sliding rod being slidably inserted into the surface of the placement groove, an elliptical block being fixedly connected to one end of the sliding rod, and a fixing groove being formed on the surface of the trapezoidal block.

[0006] The effect achieved by the above-mentioned components is as follows: by setting up a switching device, the internal maintenance of the drive power supply body can be conveniently achieved. Because the traditional drive power supply body is fixed with screws or nuts, disassembly is cumbersome. When the drive power supply body is not working, it is difficult to open the drive power supply body and know the internal condition. This causes the staff to waste a lot of time to open it to determine where to repair or replace parts, resulting in certain economic losses. The device improves the usability of the device.

[0007] Preferably, a torsion spring is fitted onto the arc surface of the round rod, and the two ends of the torsion spring are fixedly connected to the inner wall of the L-cover plate and the rotating groove of the drive power supply body, respectively.

[0008] The effect achieved by the above components is that, through the cooperation of the torsion spring and the L-shaped cover plate, the L-shaped cover plate can be kept open due to the torsion force of the torsion spring itself when the L-shaped cover plate is opened.

[0009] Preferably, a rubber pad is fixedly connected to the surface of the L-shaped cover plate, and the size of the trapezoidal block fixing groove is adapted to the size of the slide rod.

[0010] The effect achieved by the above components is that, through the cooperation of the rubber pad and the L-shaped cover plate, water can be prevented from flowing into the interior of the power supply body due to humid weather or accidental spillage on the surface of the power supply body during operation.

[0011] Preferably, a spring is fitted onto the arc surface of the slide rod, and the two ends of the spring are fixedly connected to the elliptical block and the placement groove, respectively.

[0012] The effect achieved by the above components is that, through the cooperation of the spring elliptical block and the placement groove, the slide bar can quickly return to its original position when the elliptical block is released due to the elastic force of the spring itself.

[0013] Preferably, an auxiliary device is provided on the surface of the drive power supply body. The auxiliary device includes a locking hole, which is opened on the surface of the drive power supply body. A rotating rod is fixedly connected to the inner wall of the locking hole, and a flat plate is rotatably connected to the arc surface of the rotating rod.

[0014] The effect achieved by the above-mentioned components is as follows: by setting up auxiliary devices, the user can prevent dust, fibers and other foreign objects from entering the charging port through a sealing method when the power supply body is not charging. If these small particles enter the charging port, they may accumulate inside the charging port, which may cause short circuits in key components such as circuit boards and sensors, or prevent the power supply body from charging and ensure normal operation.

[0015] Preferably, the surface of the flat plate is fixedly connected with a hook and loop fastener, the surface of the hook and loop fastener is adhered with a hook and loop flat fastener, and the hook and loop flat fastener is fixedly connected to the inner wall of the card hole.

[0016] The effect achieved by the above components is that, through the cooperation of the hook and loop side and the hook and loop flat side, the flat panel can be glued into the slot when not in use, preventing the flat panel from being opened when not in use.

[0017] Preferably, the surface of the flat plate is provided with grooves, and the size of the hook and loop fastener plane is adapted to the size of the hook and loop fastener rough surface.

[0018] The effect achieved by the above components is that, through the cooperation of the groove and the flat panel, the user can easily pull out the flat panel.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] 1. In this utility model, by setting a switch device, the internal maintenance of the drive power supply body can be conveniently achieved. Because the traditional drive power supply body is fixed with screws or nuts, disassembly is cumbersome.

This causes the staff to waste a lot of time to open it to determine where to repair or replace parts, resulting in certain economic losses. The device improves the usability of the device.

[0021] 2. In this utility model, by setting an auxiliary device, the user can prevent dust, fibers and other foreign objects from entering the charging port by sealing it when the power supply body is not charging.

Detailed Implementation

[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a stable constant current drive power supply, including a drive power supply body 1. The surface of the drive power supply body 1 is provided with a rotating groove, and the inner wall of the rotating groove is provided with a switch device 2. By setting the switch device 2, the internal maintenance of the drive power supply body 1 can be conveniently achieved. Traditionally, the drive power supply body 1 is fixed with screws or nuts, making disassembly cumbersome. When the drive power supply body 1 is not working, it is difficult to open, making it impossible to know the internal condition. This results in a significant waste of time for personnel to open it and determine where repairs or component replacements are needed, leading to certain economic losses. This invention improves the usability of the device. An auxiliary device 3 is provided on the surface of the drive power supply body 1. By setting the auxiliary device 3, when the drive power supply body 1 is not charging, it prevents dust, fibers, and other foreign objects from entering the charging port through a sealing method. If these small particles enter the charging port, they may accumulate inside, potentially causing short circuits in critical components such as circuit boards and sensors, or preventing the drive power supply body 1 from charging and ensuring normal operation.

[0030] The specific setup and function of its switching device 2 and auxiliary device 3 will be described in detail below.

[0031] Reference Figure 2 , Figure 3 and Figure 4As shown in this embodiment: the switch device 2 includes a round rod 21, which is fixedly connected to the inner wall of the rotating groove of the drive power supply body 1. An L-shaped cover plate 22 is rotatably connected to the arc surface of the round rod 21. A trapezoidal block 23 is fixedly connected to the surface of the L-shaped cover plate 22. A placement groove 24 is fixedly connected to the surface of the drive power supply body 1. A slide rod 25 is slidably inserted into the surface of the placement groove 24. An elliptical block 26 is fixedly connected to one end of the slide rod 25. A fixing groove is opened on the surface of the trapezoidal block 23. A torsion spring 27 is sleeved on the arc surface of the round rod 21. The two ends of the torsion spring 27 are fixedly connected to the L-shaped cover plate 22 and the inner wall of the rotating groove of the drive power supply body 1, respectively. A rubber pad 28 is fixedly connected to the surface of the L-shaped cover plate 22. The size of the fixing groove of the trapezoidal block 23 is adapted to the size of the slide rod 25. A spring 29 is sleeved on the arc surface of the slide rod 25. The two ends of the spring 29 are fixedly connected to the elliptical block 26 and the placement groove 24, respectively. With the cooperation of torsion spring 27 and L cover plate 22, the L cover plate 22 can be kept open due to the torsion of the torsion spring 27 itself when it is opened. With the cooperation of rubber pad 28 and L cover plate 22, water can be prevented from flowing into the interior of the drive power supply body 1 due to humid weather or accidental spillage on the surface of the drive power supply body 1 during operation. With the cooperation of spring 29, elliptical block 26 and placement groove 24, the slide bar 25 can quickly return to its original position due to the elasticity of spring 29 when the elliptical block 26 is released.

[0032] Reference Figure 5 and Figure 6 As shown, specifically, the auxiliary device 3 includes a locking hole 31, which is located on the surface of the drive power supply body 1. A rotating rod 32 is fixedly connected to the inner wall of the locking hole 31. A flat plate 33 is rotatably connected to the arc surface of the rotating rod 32. A hook and loop fastener 34 is fixedly connected to the surface of the flat plate 33. A hook and loop fastener flat surface 35 is attached to the surface of the hook and loop fastener 34. The hook and loop fastener flat surface 35 is fixedly connected to the inner wall of the locking hole 31. A groove 36 is provided on the surface of the flat plate 33. The size of the hook and loop fastener flat surface 35 is adapted to the size of the hook and loop fastener 34. Through the cooperation of the hook and loop fastener 34 and the hook and loop fastener flat surface 35, the flat plate 33 can be attached to the locking hole 31 when not in use, preventing the flat plate 33 from opening when not in use. Through the cooperation of the groove 36 and the flat plate 33, the user can easily pull out the flat plate 33.

[0033] Working principle: When the worker wants to open the L-cover 22, the worker pulls the elliptical block 26, which causes the spring 29 to open. The elliptical block 26 causes the slide rod 25 to slide. The slide rod 25 slides in the placement groove 24 and moves away from the fixed groove of the trapezoidal block 23. Due to the torsion of the torsion spring 27, the L-cover 22 is rotated. The L-cover 22 rotates on the arc surface of the round rod 21. The L-cover 22 causes the trapezoidal block 23 to rotate away from the placement groove 24, thus the worker completes the opening of the L-cover 22.

[0034] When the user needs to open the flat plate 33 for charging, the staff pulls the pull groove 36, which moves the hook and loop fastener 34. The hook and loop fastener 34 is not attached to the hook and loop fastener flat plate 35. The flat plate 33 rotates on the arc surface of the rotating rod 32. The flat plate 33 moves away from the locking hole 31, so the staff inserts the charging head into the drive power supply body 1 to complete the charging.
