Description

Technical Field

[0001] This utility model relates to the field of motor protector technology, specifically to a side-mounted motor protector. Background Technology

[0002] A motor protector is a device used to protect electric motors. It monitors abnormal conditions such as current, temperature, overload, and short circuits in the motor and automatically cuts off the power supply when a fault occurs, thereby preventing motor overload or damage. It is a critical safeguard in motor control systems and is widely used in various motor-driven equipment.

[0003] Currently, most motor protectors on the market are bolted to the distribution box. Industrial sites are usually filled with dust, moisture and various chemicals. These environmental factors pose a potential threat to the electronic components and wiring of motor protectors, which may lead to performance degradation or failure. Therefore, maintenance personnel need to disassemble, clean and inspect motor protectors regularly.

[0004] However, traditional bolt installation methods often require more tools, increasing the complexity of installation and disassembly. Therefore, a side-mounted motor protector is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a side-mounted motor protector that solves the problem that traditional bolt installation methods often require more tools, increasing the complexity of installation and disassembly.

[0006] This utility model provides the following technical solution: a side-mounted motor protector, comprising a copper plate and a motor protector, wherein the copper plate is bolted to the side wall of a distribution cabinet, and mounting brackets are fixedly connected to the top and bottom sides of the copper plate, and each mounting bracket has a mounting groove on its side. A mounting plate is fixedly connected to the side of the motor protector, and the mounting plate is slidably connected in each mounting groove. Circular grooves are provided at the top and bottom of the mounting plate, and a limiting component is provided inside each circular groove.

[0007] The above technical solution, with its limiting components, allows for tool-free installation and removal of the motor protector, reducing the complexity of installation and removal and making the process quicker and easier. The limiting components at both ends downwards also improve the installation stability of the motor protector within the mounting bracket.

[0008] As a preferred embodiment of the above technical solution, the limiting component includes a spring, which is fixedly connected to the bottom of the inner side of the circular groove, and a circular plate is fixedly connected to the top of the spring, and a circular rod is fixedly connected to the top of the circular plate.

[0009] The above technical solution facilitates the limiting of the mounting bracket and improves the stability of the motor protector installation.

[0010] As a preferred embodiment of the above technical solution, a straight rod is fixedly connected to the top end of the round rod, and a pressing head is fixedly connected to the top end of the straight rod.

[0011] The above technical solution allows the pressing head to be set up so that personnel can press down to drive the round rod into the round groove.

[0012] As a preferred embodiment of the above technical solution, each of the mounting brackets has a straight groove on its side end, and each of the straight grooves has a round opening on its side end.

[0013] The above technical solution facilitates the limiting of the circular rod by setting the circular opening.

[0014] As a preferred embodiment of the above technical solution, the round rod is inserted into the round opening.

[0015] Through the above technical solution, the circular opening is designed to limit the circular rod within the circular opening, thereby completing the limiting and fixing of the motor protector.

[0016] As a preferred embodiment of the above technical solution, the diameter of the end face of the straight rod is smaller than the width of the straight groove.

[0017] With the above technical solution, when the motor protector needs to be disassembled, the straight rod can easily pass through the straight slot, thus facilitating the disassembly of the motor protector.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention utilizes a limiting component. By pinching the pressing heads at both ends, a straight rod drives a round rod into the circular groove. At this point, the circular plate compresses the spring, causing the round rod to move out of the circular groove. Simultaneously, by pinching the pressing heads, the mounting plate is pulled out from the inside of the mounting groove. Since the diameter of the straight rod's end face is smaller than the width of the straight groove, the straight rod can pass through the groove and move out, thus completing the disassembly of the motor protector. The same method can be used to install the motor protector. Therefore, this device eliminates the need for tools during subsequent installation and disassembly of the motor protector, reducing the complexity and making the process faster and simpler. The limiting components at both ends at the lower ends improve the stability of the motor protector within the mounting frame. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] like Figures 1-4 As shown, this utility model provides a technical solution: a side-mounted motor protector, including a copper plate 1 and a motor protector 2. The copper plate 1 is bolted to the side wall of the distribution cabinet. Mounting brackets 101 are fixedly connected to the top and bottom sides of the copper plate 1. Each mounting bracket 101 has a straight groove 102 on its side end, a round opening 103 on its side end, and a mounting slot 104 on its side end. A mounting plate 201 is fixedly connected to the side end of the motor protector 2. The mounting plate 201 is slidably connected within each mounting slot 104. The motor protector 2 is connected to the mounting plate 201 and the motor protector 2. The device 2 contacts the copper plate 1, which can conduct heat to the motor protector 2 and facilitate heat dissipation. The top and bottom of the mounting plate 201 are provided with circular grooves 202. Each circular groove 202 is provided with a limiting component 3. After the copper plate 1 is first installed on the side wall of the distribution cabinet with bolts, the copper plate 1 does not need to be removed during disassembly. With the setting of the limiting component 3, it is easy to install and disassemble the motor protector 2 without the need for tools, which reduces the complexity of installation and disassembly and makes it quicker and easier. The limiting components 3 at both ends downward improve the installation stability of the motor protector 2 in the mounting bracket 101.

[0027] As one implementation method in this embodiment, such as Figure 2 , Figure 3 and Figure 4As shown, the limiting component 3 includes a spring 301, which is fixedly connected to the bottom of the inner side of the circular groove 202. A circular plate 302 is fixedly connected to the top of the spring 301. A circular rod 303 is inserted into the circular opening 103. A circular rod 303 is fixedly connected to the top of the circular plate 302. A straight rod 304 is fixedly connected to the top of the circular rod 303. The diameter of the end face of the straight rod 304 is smaller than the width of the straight groove 102. A pressing head 305 is fixedly connected to the top of the straight rod 304. In practice, by pinching the pressing heads 305 at both ends, the straight rod 304 is moved. When the round rod 303 enters the round groove 202, the round plate 302 compresses the spring 301 and retracts. At this time, the round rod 303 is no longer limited within the round opening 103. By pinching the pressing head 305 and pulling the pressing head 305, the mounting plate 201 is moved out from the inside of the mounting groove 104. Since the end diameter of the straight rod 304 is smaller than the width of the straight groove 102, the straight rod 304 can pass through the straight groove 102 and move out of the straight groove 102. At this time, the disassembly of the motor protector 2 can be completed. The installation of the motor protector 2 can be achieved in the same way.

[0028] Working principle: By pinching the pressing heads 305 at both ends, the straight rod 304 drives the round rod 303 into the round groove 202. At this time, the round plate 302 compresses the spring 301 and retracts. After the round rod 303 is no longer limited in the round opening 103, by pinching the pressing head 305, the pressing head 305 is pulled to move the mounting plate 201 out from the inside of the mounting groove 104. Since the end diameter of the straight rod 304 is smaller than the width of the straight groove 102, the straight rod 304 can pass through the straight groove 102 and move out of the straight groove 102. At this time, the disassembly of the motor protector 2 can be completed. The motor protector 2 can be installed in the same way. Therefore, this device does not require tools when installing and disassembling the motor protector 2, which reduces the complexity of installation and disassembly and makes it faster and simpler. The limiting components 3 at both ends at the lower ends improve the installation stability of the motor protector 2 in the mounting bracket 101.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
