Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] The utility model provides Figure 1-6The illustrated constant current controller includes a mounting groove 3 formed on the housing of the constant current controller body 1. A winding roller 5 is disposed within the mounting groove 3, and a dustproof net 6 is wound around the winding roller 5. A horizontal plate 7 is fixedly mounted to one end of the dustproof net 6. A movable hook and loop fastener 8 is fixedly mounted on one outer wall of the horizontal plate 7, and a fixed hook and loop fastener 2 is fixedly mounted on one outer wall of the constant current controller body 1. The movable hook and loop fastener 8 is moved by the moving horizontal plate 7 to contact the fixed hook and loop fastener 2, ultimately adhering to it. Simultaneously, the movement of the horizontal plate 7 moves the dustproof net 6 to hold the constant current controller body 1... The heat dissipation holes on the top are blocked. Since the dustproof net 6 has good air permeability, the dustproof net 6 will not affect the heat dissipation of the heat dissipation holes, but it can prevent external dust from entering the heat dissipation holes, thereby improving the service life of the constant current controller body 1. Circular plates 4 are fixedly installed at both ends of the winding roller 5. Rectangular slots 9 are opened at both ends of the two circular plates 4. Sliding rods 10 are slidably installed on the inner walls of the two mounting slots 3. Through holes are opened on the inner walls of the two mounting slots 3. The two sliding rods 10 pass through the two through holes and are respectively connected to the inner walls of the two through holes. The sliding connection is achieved by the sliding rods 10, with the ends of the two sliding rods 10 extending away from each other to the outside of the mounting groove 3. Rotating rods 12 are rotatably mounted on the ends of the two sliding rods 10 that are close to each other. To rotatably mount the rotating rods 12 onto the sliding rods 10, rotating grooves are provided on the ends of the two sliding rods 10 that are close to each other. The ends of the two rotating rods 12 that are far apart from each other extend into the two rotating grooves and are respectively fitted with bearings. The outer rings of the two bearings are fixedly connected to the inner walls of the rotating grooves. By connecting the bearings, the rotating rods 12 rotate more stably on the sliding rods 10. Rectangular plates 13 are fixedly installed at the ends of the moving rods 12 that are close to each other, and the two rectangular plates 13 extend into the two rectangular slots 9 on the side that is close to each other. Torsion springs 11 are movably sleeved on the two rotating rods 12 respectively. The dustproof net 6 is subjected to the rotational force of the torsion spring 11 through the torsion spring 11, so that the dustproof net 6 is always in a taut state and tightly attached to the constant current controller body 1, blocking the heat dissipation holes. One end of the two torsion springs 11 is fixedly connected to the corresponding rectangular plates 13, and the other end of the two torsion springs 11 is fixedly connected to the corresponding sliding rods 10.
[0023] In order to limit the rotation plate 17 so that the winding roller 5 drives the rectangular clamping plate 13 to rotate when it rotates, but cannot drive the sliding rod 10 to rotate, so that the torsion spring 11 can change from a free state to a stressed state, the two sliding rods 10 are respectively fixedly installed on the ends of the two sliding rods 10 that are far apart from each other. Two limit rods 16 are slidably installed on the two rotation plates 17 respectively, and both limit rods 16 are fixedly connected to the constant current controller body 1.
[0024] In order to ensure that the rectangular plate 13 is always positioned in the rectangular slot 9 to hold the circular plate 4 without being subjected to other external forces, the winding roller 5 is fixedly installed in the mounting slot 3. Elastic pull ropes 18 are fixedly installed on the two rotating plates 17 respectively, and both elastic pull ropes 18 are fixedly connected to the constant current controller body 1.
[0025] To protect the torsion springs 11 and prevent external dust from adhering to them and affecting their service life, protective covers 15 are movably fitted onto each of the two torsion springs 11. The two protective covers 15 are fixedly connected to the two rectangular plates 13, and the two protective covers 15 are rotatably connected to the two sliding rods 10. To rotatably mount the protective covers 15 onto the sliding rods 10, a rectangular hole is opened at one end of the protective cover 15 and a circular hole is opened at the other end. A connecting bearing is fitted inside the circular hole and is fitted onto the sliding rod 10.
[0026] Through holes are provided on the inner walls of both sides of the mounting groove 3. Two sliding rods 10 pass through the two through holes and are slidably connected to the inner walls of the two through holes respectively.
[0027] The working principle of the constant current controller provided by this utility model is as follows: In the initial state, the elastic cord 18 is in a stretched state and the torsion spring 11 is in a free state. The elastic cord 18 keeps the rectangular clamping plate 13 in the rectangular clamping groove 9 on one side without being subjected to external force, thereby holding the circular plate 4, and fixing the winding roller 5 in the mounting groove 3. When it is necessary to prevent external dust from entering the heat dissipation hole, the operator moves the horizontal plate 7 to move the movable hook and loop fastener 8 to contact the fixed hook and loop fastener 2, and finally adheres to the fixed hook and loop fastener 2. At the same time, the movement of the horizontal plate 7 moves the dustproof net 6 to maintain the constant current. The heat dissipation holes on the controller body 1 are blocked. Since the dustproof net 6 has good air permeability, the dustproof net 6 will not affect the heat dissipation of the heat dissipation holes, but it can prevent external dust from entering the heat dissipation holes, thereby improving the service life of the constant current controller body 1. When the dustproof net 6 is broken and needs to be replaced, the moving rotating plate 17 drives the rectangular card plate 13 to move out of the rectangular card slot 9. At this time, the circular plate 4 changes from the clamped state to the free state. The operator moves the winding roller 5 outward, and the winding roller 5 and the dustproof net 6 can be removed from the device to replace the dustproof net 6. The process is simple, fast and efficient.
[0028] Compared with related technologies, the programmable constant current controller provided by this utility model has the following advantages:
[0029] This utility model provides a programmable constant current controller. A movable horizontal plate 7 moves a movable hook and loop fastener 8 to contact and adhere to a fixed hook and loop fastener 2. Simultaneously, the movement of the horizontal plate 7 moves a dustproof net 6 to block the heat dissipation holes on the constant current controller body 1. Because the dustproof net 6 has good air permeability, it does not affect the heat dissipation of the holes, but prevents external dust from entering, thus improving the service life of the constant current controller body 1. A movable rotating plate 17 moves a rectangular card plate 13 out of the rectangular card slot 9. The operator can then move the winding roller 5 outwards to remove the winding roller 5 and the dustproof net 6 from the device for replacement. The process is simple, fast, and highly efficient.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
