Description

Technical Field

[0001] The present invention relates to the technical field of motor protection, and specifically provides a protection device for a motor. Background Art

[0002] Generally, a base body is provided on a motor and installed at both ends of the motor, and the base body is fixed to the motor by bolts; According to a Chinese patent, a protection device for a motor is disclosed, and its publication number is: CN209358329U; in this patent, two base bodies on both sides of the motor are fixed to the motor by bolts. When the bolts are tightened, the support feet on the reinforcement plate abut against the outer wall of the motor, and the reinforcement plate props up the connecting seat to prevent the connecting seat from deforming and being damaged due to the tightening of the bolts; when the bolts are tightened, the arc-shaped support plate props up the reinforcement plate to prevent the reinforcement plate from deforming under force, thereby increasing the strength of the reinforcement plate. The acting force transmitted by the support plate is transmitted to the connecting seat through the reinforcement plate, so that the reinforcement plate can better prop up the connecting seat, and the connecting seat is not easily damaged; the setting of the anti-slip strip increases the friction between the support feet and the motor, making it difficult for the reinforcement plate to slide under force, so that the reinforcement plate can better prop up the connecting seat; the setting of the support feet facilitates the installation of the anti-slip strip; the setting of the rubber pad increases the friction between the support plate and the motor, enabling the support plate to well prop up the reinforcement plate, so that the reinforcement plate further props up the connecting seat to prevent the connecting seat from being damaged under force; the connecting plate connects the two connecting seats, and several reinforcing columns prop up the connecting plate, so that the adjacent two connecting seats and the connecting plate are more integrated. Furthermore, after the connecting seat is deformed under force, the base body and the connecting plate can decompose part of the external force, so that the connecting seat is not easily broken and damaged under force; the arc-shaped connecting plate can better support and strengthen the connecting seat, further making the connecting seat not easily damaged; However, the exterior of the motor in this patent does not have a protection structure. When the motor is collided, the impact directly contacts the motor, easily causing damage to the motor. For this reason, we propose a protection device for a motor. Summary of the Invention

[0003] The purpose of the present invention is to provide a protection device for a motor to solve the problems raised in the above background art.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] Embodiment 1: The preferred embodiment of the protection device for a motor provided by the present invention is as follows Figures 1 to 8 shown: A protection device for a motor includes a motor 1. A seat body 2 is sleeved on the outer wall of the motor 1. By setting an anti-slip pad, the friction between the seat body 2 and the ground can be increased, and the stability during the operation of the motor can be improved. The anti-slip pad is made of AB glue. A vertical protection mechanism 3 is arranged between the seat body 2 and the motor 1.

[0020] The vertical protection mechanism 3 includes a protection plate 301. Limited position clamping plates 302 are fixedly installed on both sides of the protection plate 301. A limited position clamping groove 303 is opened at the top end of the seat body 2. The limited position clamping plates 302 are clamped in the limited position clamping groove 303. An arc plate 304 is fixedly installed at the bottom end of the protection plate 301. The limited position clamping plates 302 and the limited position clamping groove 303 are adapted to each other. The arc plate 304 is made of elastic PVC material, so that the arc plate can generate a certain deformation, thereby playing a certain buffering role. By setting the limited position clamping plates 302 and the limited position clamping groove 303, the protection plate 301 can be fixedly slid on the seat body 2. The arc plate 304 contacts the top surface of the motor 1. A sleeve 306 is fixedly installed at the bottom end of the protection plate 301. A top block 308 is inserted at the bottom end of the sleeve 306. The top block 308 contacts the inner wall of the arc plate 304. A first spring 307 is arranged inside the sleeve 306. One end of the first spring 307 is fixedly installed at the top end of the inner wall of the sleeve 306, and the other end of the first spring 307 is fixedly installed at the top end of the top block 308. Heat dissipation holes 305 are opened on the arc plate 304. The number of the sleeve 306, the top block 308 and the first spring 307 is several, and the number of the heat dissipation holes 305 is several. By setting the heat dissipation holes 305, a certain heat dissipation effect can be achieved on the motor 1, avoiding the accumulation of heat due to the inability of air to circulate, which affects the normal operation of the motor 1.

[0021] Install the protection plate 301 on the seat body 2 so that the limited position clamping plates 302 are snapped into the limited position clamping groove 303. When the motor 1 is vertically collided, the protection plate 301 moves downward. The protection plate 301 squeezes the arc plate 304, causing the arc plate 304 to deform, making the top block 308 contract into the sleeve 306, and the top block 308 compresses the first spring 307, thereby playing a good buffering role for the collision, reducing the impact generated by the collision on the motor 1, playing a certain protection role for the vertical collision of the motor 1, and solving the problem that the structure for protecting the outside of the motor 1 in the comparative document is not available, resulting in the impact directly contacting the motor 1 when the motor 1 is collided, which easily causes damage to the motor 1.

[0022] Embodiment 2: On the basis of Embodiment 1, the preferred embodiment of the protection device for a motor provided by the present invention is as follows Figures 1 to 8As shown in the figure: A limiting mechanism 4 is provided at the top end of the seat body 2.

A limiting rod 405 is fixedly installed on the inner wall of the limiting chute 403. The limiting rod 405 movably penetrates through the limiting slide plate 402 through the limiting rod hole 404. The limiting slide plate 402 is adapted to the limiting chute 403, and the limiting rod 405 is adapted to the limiting rod hole 404. By providing the limiting slide plate 402 and the limiting chute 403, the baffle 401 can be fixedly slid on the seat body 2. By providing the limiting rod 405, a limiting effect can be exerted on the second spring 406 to ensure the stability of the second spring 406 during compression. A second spring 406 is wound around the outer wall of the limiting rod 405. One end of the second spring 406 is fixedly installed on the inner wall of the limiting chute 403, and the other end of the second spring 406 is fixedly installed on one side of the limiting slide plate 402. A fixing plate 407 is fixedly installed at the top end of the seat body 2. A jack 408 is opened at the bottom end of the fixing plate 407. The baffle 401 is inserted into the jack 408.

When the limiting card plate 302 is snapped into the limiting card slot 303, the baffle 401 is released. The limiting slide plate 402 drives the baffle 401 to perform a reset movement under the reset action of the second spring 406, so that the baffle 401 is above the limiting card slot 303, and the baffle 401 is inserted into the jack 408, thereby limiting the limiting card plate 302 to prevent the limiting card plate 302 from disengaging from the limiting card slot 303, preventing the lateral protection mechanism 5 from detaching from the seat body 2, ensuring the normal use of the lateral protection mechanism 5, and facilitating the disassembly of the vertical protection mechanism 3 by personnel and the maintenance of the motor 1 by personnel, with strong practicability.
