[0002] An electric motor starter is a device used to control and start electric motors. By adjusting voltage, current, or starting method, it enables smooth starting, stopping, and protection of the motor, reducing the impact on the power grid and mechanical load, and extending equipment life. During the use of electric motors, starters are used to facilitate control of the motor's operation and ensure the normal operation of the equipment, thus guaranteeing the normal starting of the motor.

[0003] During use, starters control the starting and stopping of the motor by rotating their buttons, and the internal components are protected by the motor housing. However, existing starters are susceptible to contamination from external dust, impurities, and moisture, which can reduce their lifespan. Therefore, this paper proposes a motor starter that avoids environmental pollution to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a motor starter that avoids external environmental pollution, so as to solve the problem mentioned in the background art that the existing starters are contaminated by external dust, impurities and moisture during use, thereby reducing the service life of the starter.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a motor starter that avoids pollution from the external environment, comprising a starter, wherein the starter is provided with a fixed frame on its upper end face, and a rotating rod is inserted inside the fixed frame, wherein the two ends of the rotating rod are respectively provided with threads on the outer wall, and the fixed frame is provided with bolt holes at both ends, wherein the rotating rod is connected to a protective cover on the outer wall through an L-shaped connecting plate, and the protective cover is provided with rubber strips on the four outer walls; The fixing frame has a slider on its lower end face, and the starter has a corresponding groove on its upper end face. The slider is inserted into the groove, and the groove has a spring on one side. One end of the spring is connected to the inside of the starter, and the other end of the spring is connected to the slider. The protective cover has rubber locking plates on its inner walls on all four sides, and the starter has a corresponding locking groove on its front side. The rubber locking plates are locked into the locking groove. The starter has an L-shaped fixing frame inside at the rear, and the L-shaped fixing frame is a hollow structure. The L-shaped fixing frame has air inlet pipes on the inner side and multiple sets of ventilation pipes on the outer side at the lower end of the L-shaped fixing frame. Dustproof nets are inserted inside the ventilation pipes.

[0006] Preferably, the protective cover forms a rotating structure with the starter via a rotating rod, and the rotating rod and the fixed frame form a spiral locking structure.

[0007] Preferably, the rotating rod is inserted into the slide groove by a spring and a slider to form a sliding structure with the starter, and the protective cover is inserted into the locking groove by a rubber locking plate to form a locking and limiting structure with the starter.

[0008] Preferably, the starter has an internal structure that is connected to the air inlet pipe and the ventilation pipe through an L-shaped fixing frame.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: The protective cover of the motor starter that avoids external environmental pollution forms a rotating structure with the starter through a rotating rod, and the rotating rod and the fixed frame form a spiral locking structure. Thus, while protecting the front components of the starter through the protective cover, the rubber strips on its four sides further increase the sealing of the connection between the protective cover and the starter, thereby preventing external impurities from contaminating the starter's operating button components. The rotating rod of this device forms a sliding structure with the starter through a spring and a slider inserted into a sliding groove, and the protective cover forms a locking and limiting structure with the starter through a rubber locking plate inserted into a locking groove. Thus, under the action of the spring, the protective cover further increases the tight protection effect of the starter. At the same time, the locking rubber locking plate assembly further prevents external moisture from affecting the starter. The starter of this device forms a connected structure through an L-shaped fixing frame, an air inlet pipe and a ventilation pipe. Thus, the hollow L-shaped fixing frame and multiple sets of ventilation pipes ensure the heat dissipation effect inside the starter while preventing external dust and impurities from directly entering the starter and affecting related components.

[0012] 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.

[0013] Please see Figure 1-5 This utility model provides a technical solution: a motor starter that avoids pollution from the external environment, including a starter 1, a fixed frame on the upper end face of the starter 1, and a rotating rod 2 inserted inside the fixed frame, the two ends of the rotating rod 2 are respectively provided with threads on the outer wall, and the fixed frame is provided with bolt holes at both ends, the rotating rod 2 is connected to the protective cover 3 through an L-shaped connecting plate on the outer wall, and the protective cover 3 is provided with rubber strips 4 on the four outer walls.

[0014] Furthermore, the protective cover 3 forms a rotating structure with the starter 1 through the rotating rod 2, and the rotating rod 2 forms a spiral locking structure with the fixed frame. Thus, the threaded rotating rod 2 facilitates the rotation of the protective cover 3 while increasing the overall stability of the protective cover 3. At the same time, the rubber strip 4 on the outside of the protective cover 3 further prevents external impurities from entering the starter 1 and affecting its operation button assembly.

[0015] The mounting bracket has a slider on its lower end face, and the starter 1 has a corresponding groove on its upper end face. The slider is inserted into the groove, and a spring 5 is provided on one side of the groove. One end of the spring 5 is connected to the inside of the starter 1, and the other end of the spring 5 is connected to the slider. The protective cover 3 has rubber locking plates 6 on its inner walls on all four sides, and the starter 1 has a corresponding locking groove on its front side. The rubber locking plates 6 are locked into the locking groove.

[0016] Furthermore, the rotating rod 2, through the spring 5 and the slider, is inserted into the slide groove to form a sliding structure with the starter 1, and the protective cover 3, through the rubber locking plate 6, is inserted into the locking groove to form a locking and limiting structure with the starter 1. Thus, under the action of the spring 5 and the rubber locking plate 6, the connection and sealing between the protective cover 3 and the starter 1 are further increased, thereby preventing external dust or moisture from contaminating the starter 1.

[0017] The starter 1 has an L-shaped fixing frame 7 located at the rear of the internal part. The L-shaped fixing frame 7 is a hollow structure. The inner side of the L-shaped fixing frame 7 is provided with air inlet pipes, and the lower end of the L-shaped fixing frame 7 is provided with multiple sets of ventilation pipes 8 on the outer side. Dustproof nets 9 are inserted into the ventilation pipes 8. It should be noted that this utility model is a motor starter that avoids pollution from the external environment. All components are standard parts or parts known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0018] Furthermore, the starter 1 is internally connected by an L-shaped mounting bracket 7, an air inlet pipe, and a ventilation pipe 8. This L-shaped mounting bracket 7 and multiple ventilation pipes 8 ensure the heat dissipation effect inside the starter 1, while the dustproof net 9 and L-shaped mounting bracket 7 prevent external impurities from directly entering the starter 1 and coming into direct contact with the internal components, thus avoiding contamination.

[0019] Working Principle: When using a motor starter designed to prevent external environmental pollution, during the placement of starter 1, the protective cover 3 and its related components are pulled outwards. The operator then rotates the protective cover 3 using the rotating rod 2, bringing it to the front of starter 1. The protective cover 3 is then released, causing the spring 5 to return to its original position after losing tension, allowing the protective cover 3 to move towards the front of starter 1. This effectively ensures the connection between the protective cover 3 and starter 1 under the action of the rotating rod 2 and spring 5. Simultaneously, the rubber strip 4 on the outside of the protective cover 3 further prevents impurities from the external environment from entering the interior through the connection between the protective cover 3 and starter 1 and contaminating the related components. After the protective cover 3 is in place, the rubber locking plate 6 engages with the locking groove on starter 1. The locking rubber locking plate 6 further prevents external moisture from entering the starter 1 and affecting its operating components, thereby increasing the overall protective effect of the protective cover 3 on the starter 1. During normal use, the starter 1 can form a communication structure with the outside through the hollow L-shaped fixing bracket 7, air inlet pipe, and ventilation pipe 8, so that the heat dissipation inside the starter 1 can be effectively guaranteed through multiple sets of ventilation pipes 8. At the same time, multiple sets of dustproof nets 9 and L-shaped fixing bracket 7 can prevent external impurities or moisture from entering the starter 1 and directly contacting related components, thus preventing contamination. In addition, the air inlet pipes in this device are respectively located above the ventilation pipes 8, and the ventilation pipes 8 are inclined structures, further preventing external impurities from contaminating the starter 1. This is the usage process of the motor starter that avoids external environmental pollution.

[0020] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
