Description

Technical Field

[0001] This utility model relates to the field of low-voltage controller technology, specifically a multi-functional low-voltage controller. Background Technology

[0002] A low-voltage controller is a device used to control and protect low-voltage circuits and electrical equipment. It is widely used in industrial production, building electrical systems, and daily electrical systems. It can precisely control the starting, stopping, forward and reverse rotation, and speed adjustment of electrical equipment such as motors. For example, in an industrial production line, a low-voltage controller can control the motor to start or stop according to production needs to control the operation of the conveyor belt. It has multiple protection mechanisms. When the circuit experiences abnormal conditions such as overload, short circuit, undervoltage, or overvoltage, it will quickly act to cut off the circuit and protect the equipment and lines from damage. For example, in a household circuit, once a short circuit occurs, the low-voltage controller can instantly cut off the power supply. It can monitor various circuit parameters in real time, such as voltage, current, and power, and provide feedback to the operator through indicator lights, displays, and other means.

[0003] An investigation revealed that a multifunctional low-voltage controller (publication number: CN 217308054U) is disclosed in Chinese Utility Model Information. It comprises a first fixing member, a second fixing member, and a second limiting block. The low-voltage controller body is slidably sleeved on the inner walls of the first and second fixing members. A second connecting rod and a first limiting rod are slidably sleeved within the second fixing member. The first connecting rod and the second limiting rod are slidably sleeved within the inner wall of the first fixing member. The second limiting rod is slidably sleeved within the first limiting rod, and the first connecting rod is slidably sleeved within the second connecting rod. A third bolt and a fourth bolt are threadedly connected within the first fixing member. A first limiting block is fixedly installed on the inner wall of the first limiting rod. Connecting blocks are installed at both ends of the second limiting block. This utility model satisfies the requirements of a low-voltage controller, providing rapid protection against external compression, and allowing for adjustment and limiting according to actual size.

[0004] Although the aforementioned patent prevents damage to the low-voltage controller body from external pressure by setting the first and second limit blocks, since one side of the low-voltage controller is used to connect the wiring, the wiring is exposed to the external environment for a long time without any protection and the wiring is messy. This situation not only affects the overall appearance, but also increases the risk of wire wear, thereby causing faults such as short circuits and open circuits, which in turn poses a serious threat to the stable operation of the entire equipment.

[0005] Therefore, this utility model provides a multifunctional low-voltage controller to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This invention provides a multifunctional low-voltage controller, which aims to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: It includes a low-voltage controller body, with L-shaped base plates fixedly mounted on both the front and back sides of the low-voltage controller body by bolts.

A protective frame is fixedly mounted on the lower surface of the L-shaped base plate by bolts. One side surface of the protective frame has a receiving portion, the inner arc surface of which is fitted into one side of the low-voltage controller body. The upper surface of the protective frame has heat dissipation holes corresponding to the internal low-voltage controller body. A wire-passing hole A is located at the bottom of one side surface of the receiving portion, and a wire-passing hole B is located at the edge of one side surface of the receiving portion. The inner arc surface of the wire-passing hole A corresponds to the wiring holes.

[0010] As a preferred technical solution of this application, a hinge rod is rotatably connected to one side surface of the receiving part near the wire hole A, a torsion spring is sleeved in the middle of the outer arc surface of the hinge rod, and a baffle plate is connected to both sides of the outer arc surface of the hinge rod.

[0011] As a preferred technical solution of this application, the shielding plate has a mounting hole on one side surface, the shielding plate has an L-shaped structure and is placed on one side of the wire hole B and the wire hole A, and the number of the protective frame is two, which are fixedly installed on the front and rear sides of the low voltage controller body.

[0012] As a preferred technical solution of this application, a protective plate is fixedly installed on the surface of the protective frame, and a connecting part is provided on both sides of one side surface of the protective plate.

Threaded holes are provided at the four corners of the upper surface of the mounting plate, and the mounting plate is placed on the top of the low-voltage controller body through the threaded holes on the surface.

[0015] As a preferred technical solution of this application, the upper surface of the mounting plate is provided with heat dissipation fins, and the heat dissipation fins and the low-voltage controller body are in a vertical plane.

[0016] (III) Beneficial Effects

[0017] 1. The shield and wiring holes not only provide reliable protection for the internal wiring harness and effectively reduce the risk of wear and tear on the lines caused by external factors, but also provide operators with a convenient and efficient way to perform line maintenance, thus ensuring the stable operation of the entire low-voltage controller system.

[0018] 2. The protective plates are evenly distributed symmetrically on the frame of the low-voltage controller body. This symmetrical distribution not only enhances the overall protection effect, but also provides a comprehensive protective barrier for the low-voltage controller body.

[0019] 3. By mounting the mounting plate on the low-voltage controller body over a large area, heat is transferred from the internal components to the heat dissipation fins through thermal conduction. Due to the large contact area between the fins and the air, the heat convection process is accelerated, and the heat is quickly dissipated into the surrounding air, reducing the operating temperature, slowing down the aging rate of components, and extending the service life of the low-voltage controller.

[0026] 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.

[0027] This utility model provides a controller, such as Figures 1 to 4 As shown, the device includes a low-voltage controller body 1. L-shaped base plates 2 are bolted to both the front and back of the low-voltage controller body 1. The upper surface of the L-shaped base plate 2 has threaded holes, and one side surface has wiring holes 3. A protective frame 4 is bolted to the lower surface of the L-shaped base plate 2. One side surface of the protective frame 4 has a receiving portion 401, the inner arc surface of which fits into one side of the low-voltage controller body 1. The upper surface of the protective frame 4 has heat dissipation holes 5, which correspond to the internal low-voltage controller body 1. The bottom surface of one side surface of the receiving portion 401... The receiving part 401 has a wire hole A6 and a wire hole B7 on one side edge of the receiving part 401. The inner arc surface of the wire hole A6 corresponds to the wiring hole 3. A hinge rod 8 is rotatably connected to one side surface of the receiving part 401 near the wire hole A6. A torsion spring 9 is sleeved in the middle of the outer arc surface of the hinge rod 8. A baffle plate 10 is connected to both sides of the outer arc surface of the hinge rod 8. A mounting hole is opened on one side surface of the baffle plate 10. The baffle plate 10 has an L-shaped structure and is placed on one side of the wire hole B7 and the wire hole A6. There are two protective frames 4, which are fixedly installed on the front and rear sides of the low-voltage controller body 1.

[0028] A receiving part 401 is provided on one side of the protective frame 4. The receiving part 401 is stably connected to the L-shaped base plate 2 on the low-voltage controller body 1. On the same side of the protective frame 4, the shielding plate 10 is fixed together with the protective frame 4 by the hinge rod 8, so that the shielding plate 10 is exactly in front of the wire hole A6 and the wire hole B7.

[0029] When it is necessary to adjust or repair the internal wiring harness connection, the operator only needs to rotate the hinge rod 8 to easily open the cover plate 10 and switch it to the second position. At this time, the operator can easily make precise adjustments or perform detailed repairs on the internal wiring harness connection through the wire hole A6 and the wire hole B7.

[0030] After all adjustments and maintenance are completed, the operator only needs to loosen the cover plate 10. At this time, the torsion spring 9, which is tightly connected to the cover plate 10, will quickly take effect and rotate to reset under its own torque, thereby driving the cover plate 10 to return smoothly to its original position and cover the top of the wire harness. This design not only provides reliable protection for the internal wire harness and effectively reduces the risk of wear and tear on the line caused by external factors, but also provides the operator with a convenient and efficient way to perform line maintenance, effectively ensuring the stable operation of the entire low-voltage controller system.

[0031] A protective plate 11 is fixedly installed on the surface of the protective frame 4. A connecting part 110 is provided on both sides of one side surface of the protective plate 11. A bent edge 111 is provided between the connecting parts 110 on both sides of the protective plate 11. The bent edge 111 is attached to the low-voltage controller body 1. There are four protective plates 11, which are attached to the low-voltage controller body 1 in pairs. The upper surface of the connecting part 110 abuts against the inner arc surface of the receiving part 401.

[0032] The protective plate 11 adopts an elastic structure design, and the connecting parts 110 on both sides can be movably engaged with the inner arc surface of the receiving part 401. Based on this ingenious design, the four protective plates 11 can be evenly distributed on the frame of the low-voltage controller body 1 in a symmetrical form. This symmetrical distribution not only enhances the overall protection effect, but also provides an all-round protective barrier for the low-voltage controller body 1.

[0033] Mounting plates 12 are fixedly mounted on the upper surfaces of the two protective plates 11 by bolts. Threaded holes are provided at the four corners of the upper surface of the mounting plates 12. The mounting plates 12 are placed on the top of the low-voltage controller body 1 through the threaded holes on the surface. Heat dissipation fins 13 are provided on the upper surface of the mounting plates 12. The heat dissipation fins 13 and the low-voltage controller body 1 are in the vertical plane.

[0034] The mounting plate 12 is installed on the low-voltage controller body 1 over a large area, so that heat is transferred from the internal components to the heat dissipation fins 13 through thermal conduction. Since the fins have a large contact area with the air, the heat convection process is accelerated, and the heat is quickly dissipated into the surrounding air, reducing the operating temperature, slowing down the aging rate of the components, and extending the service life of the low-voltage controller.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
