Description

Technical Field

[0001] This utility model relates to the field of enclosed motor housings, and more particularly to an enclosed motor housing with self-circulating cooling. Background Technology

[0002] A closed motor housing is a self-circulating, closed motor housing mainly used to protect and cool the motor. It is quite common in existing technologies.

[0003] Existing technologies, such as the utility model patent with publication number CN208571747U, disclose a closed generator housing and rotor for engineering vehicles. This patent uses a rear end cover, a stator, and a front end cover assembled sequentially. The rear end cover and the front end cover are both integrally cast aluminum and have through holes only at both ends. A rotating shaft runs through the center of the rear end cover, the stator, and the front end cover, and the stator is mounted on the rotating shaft. A fan is mounted on one side of the front end cover, and a pulley is mounted on the other side of the fan. A nut is mounted on the other end of the pulley. The closed generator housing and rotor of this utility model for engineering vehicles have a sealed structure except for the through holes of the rotating shaft, which prevents dust and water from entering the generator to the greatest extent, prevents electromechanical failures, and increases service life. Furthermore, the rotor uses permanent magnets instead of coils, which greatly reduces production costs.

[0004] The inventor discovered in his daily work that the existing method of installing the connecting pipe onto the connecting pipe involves multiple bolts, and the use of screwdrivers and other tools is required to secure the connecting pipe. This method is cumbersome and leads to low work efficiency. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the existing technology uses multiple bolts to install the connecting pipe onto the connecting pipe, and personnel need to use screwdrivers and other tools to fix the connecting pipe firmly during the installation process. This installation method is very cumbersome and leads to low work efficiency. Therefore, a self-circulating cooling closed motor housing is proposed.

[0006] To solve the above technical problems, this utility model provides a self-circulating cooling enclosed motor housing, comprising: a motor housing body and a mounting structure. Two connecting pipes are installed on the inner wall of the motor housing body. A connecting pipe is mounted on the arc surface of the connecting pipe via the mounting structure. The arc surface of the connecting pipe is provided with the mounting structure, which includes a fixing ring and a positioning ring. The fixing ring is fixedly connected to the connecting pipe, and the positioning ring is fixedly connected to the connecting pipe. Two fixing brackets are fixedly connected to the arc surface of the fixing ring. Two limiting grooves are formed on the inner wall of the fixing brackets. Moving blocks are slidably connected to the inner wall of the limiting grooves. A moving plate is fixedly connected to the side of the two moving blocks that are close to each other. The upper surface of the moving blocks is flush with the limiting groove. A spring is provided between the two ends of the spring, which are fixedly connected to the moving block and the limiting groove, respectively. Two positioning grooves are opened on the inner wall of the positioning ring. A locking block is fixedly connected to the side of the two moving plates that are close to each other.

The inclined surface of the pressing block abuts against the inclined surface of the top block. A rotating ring is threadedly connected to the arc surface of the positioning ring. The rotating ring is rotatably connected to the moving ring. Two positioning plates are fixedly connected to the side of the fixed ring that is close to the positioning ring. Two auxiliary grooves are opened on the inner wall of the positioning ring. The auxiliary grooves are slidably connected to the positioning plates.

[0007] The effect achieved by the above components is that when personnel need to connect and install the connecting pipe onto the connecting pipe, they can move the positioning ring to make the positioning plate slide into the inner wall of the auxiliary groove and the locking block slide into the inner wall of the positioning groove, thereby making it convenient for personnel to quickly connect and install the connecting pipe onto the connecting pipe.

[0008] Preferably, the arc surface of the rotating ring is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are evenly provided on the rotating ring.

[0009] The effect achieved by the above components is that the anti-slip groove can increase the friction between the person's hand and the rotating ring, and can prevent the person from slipping during the rotation of the ring.

[0010] Preferably, a guide block is fixedly connected to the side of the positioning plate away from the fixing ring, and the guide block is slidably connected to the auxiliary groove.

[0011] The effect achieved by the above components is that the guide block can limit the positioning plate, making it easy for personnel to slide the positioning plate into the inner wall of the auxiliary groove.

[0012] Preferably, a limiting rod is fixedly connected to the inner wall of the limiting groove, and the limiting rod is slidably connected to the moving block.

[0013] The effect achieved by the above components is that the limiting rod can limit the movement of the moving block and prevent the moving block from becoming misaligned during the sliding process on the inner wall of the limiting groove.

[0014] Preferably, a sealing gasket is fixedly connected to the side of the connecting pipe near the connecting pipe, and the sealing gasket is fixedly connected to the connecting pipe.

[0015] The effect achieved by the above components is that the sealing gasket can increase the sealing between the connecting pipe and the connecting pipe, and can prevent liquid from flowing out between the connecting pipe and the connecting pipe.

[0016] Preferably, the movable plate is a stainless steel plate.

[0017] The effect achieved by the above components is that the stainless steel plate has high strength and good wear resistance, which can prevent the moving plate from deforming during short-term use.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] Please see Figure 1 The present invention provides a self-circulating cooling closed motor housing, comprising: a motor housing body 1 and a mounting structure 3. Two connecting pipes 2 are installed on the inner wall of the motor housing body 1. A connecting pipe 4 is installed on the arc surface of the connecting pipe 2 by means of the mounting structure 3. The arc surface of the connecting pipe 2 is provided with the mounting structure 3.

[0029] In the embodiments of this utility model, please refer to Figures 2 to 5The installation structure 3 includes a fixing ring 301 and a positioning ring 311. The fixing ring 301 is fixedly connected to the connecting pipe 2, and the positioning ring 311 is fixedly connected to the connecting pipe 4. Two fixing brackets 302 are fixedly connected to the arc surface of the fixing ring 301. Two limiting grooves 303 are opened on the inner wall of the fixing brackets 302. Moving blocks 306 are slidably connected to the inner wall of the limiting grooves 303. Moving plates 307 are fixedly connected to the side of the two moving blocks 306 that are close to each other. A spring 305 is provided between the upper surface of the moving block 306 and the limiting groove 303. The two ends of the spring 305 are fixedly connected to the moving block 306 and the limiting groove 303 respectively. Two positioning grooves 308 are opened on the inner wall of the positioning ring 311. The two moving plates 307 are close to each other. On the side closest to the positioning ring 307, a locking block 319 is fixedly connected. The locking block 319 is slidably connected to the positioning groove 308. On the side of the moving plate 307 away from the locking block 319, a top block 310 is fixedly connected. On the arc surface of the positioning ring 311, a moving ring 309 is slidably connected. On the arc surface of the moving ring 309, two pressing blocks 318 are fixedly connected. The inclined surface of the pressing block 318 abuts against the inclined surface of the top block 310. On the arc surface of the positioning ring 311, a rotating ring 312 is threadedly connected. The rotating ring 312 is rotatably connected to the moving ring 309. On the side of the fixed ring 301 closest to the positioning ring 311, two positioning plates 315 are fixedly connected. On the inner wall of the positioning ring 311, two auxiliary grooves 314 are opened. The auxiliary grooves 314 are slidably connected to the positioning plates 315. When personnel need to connect and install the connecting pipe 4 onto the connecting pipe 2, they can move the positioning ring 311 to slide the positioning plate 315 into the inner wall of the auxiliary groove 314 and the locking block 319 into the inner wall of the positioning groove 308. This allows personnel to quickly and easily connect and install the connecting pipe 4 onto the connecting pipe 2. The arc surface of the rotating ring 312 is provided with several anti-slip grooves 313, which are evenly distributed on the rotating ring 312. The anti-slip grooves 313 can increase the friction between the personnel's hands and the rotating ring 312, preventing slippage during the rotation of the rotating ring 312. A guide block 316 is fixedly connected to the side of the positioning plate 315 away from the fixed ring 301, and the guide block 316 is slidably connected to the auxiliary groove 314. The guide block 316 can limit the positioning plate 315, allowing personnel to easily slide the positioning plate 315 into the inner wall of the auxiliary groove 314. A limiting rod 304 is fixedly connected to the inner wall of the limiting groove 303, and the limiting rod 304 is slidably connected to the moving block 306. The limiting rod 304 can limit the moving block 306, preventing misalignment during sliding within the limiting groove 303. A sealing gasket 317 is fixedly connected to the side of the connecting pipe 2 near the connecting pipe 4, and the sealing gasket 317 is fixedly connected to the connecting pipe 4. The sealing gasket 317 increases the sealing between the connecting pipe 2 and the connecting pipe 4, preventing liquid from flowing out between them. The moving plate 307 is made of stainless steel. Stainless steel has high strength and good wear resistance, preventing deformation of the moving plate 307 during short-term use.

[0030] The working principle of the self-circulating cooling enclosed motor housing provided by this utility model is as follows: When personnel need to connect and install the connecting pipe 4 onto the connecting pipe 2, they can first move the connecting pipe 4. The connecting pipe 4 drives the positioning ring 311 to move closer to the connecting pipe 4. The positioning ring 311 drives the moving ring 309 and the rotating ring 312 to move closer to the fixed ring 301. The moving ring 309 drives the two pressing blocks 318 to move closer to the fixed ring 301 until the positioning ring 311 slides onto the arc surface of the connecting pipe 2. Then, the positioning ring 311 slides on the arc surface of the connecting pipe 2. During the process, the guide block 316 and positioning plate 315 slide into the inner wall of the auxiliary groove 314, the positioning ring 311 abuts against the fixed ring 301, and the connecting pipe 4 abuts against the sealing gasket 317. The guide block 316 can limit the positioning plate 315, making it easy for personnel to slide the positioning plate 315 into the inner wall of the auxiliary groove 314. Then, personnel rotate the rotating ring 312, causing it to move closer to the fixed ring 301. The sealing gasket 317 increases the sealing between the connecting pipe 2 and the connecting pipe 4, preventing liquid from flowing out between them. Then, the rotating ring 312 drives... The moving ring 309 moves towards the fixed ring 301, causing the two pressing blocks 318 to move towards the top block 310. The anti-slip groove 313 on the inner wall of the rotating ring 312 increases the friction between the operator's hand and the rotating ring 312, preventing slippage during rotation. This continues until the pressing blocks 318 abut against the top block 310. Then, the pressing blocks 318 move the top block 310 towards the positioning groove 308, which in turn moves the moving plate 307 towards the fixed ring 301. The two moving blocks 306 and the locking block 319 are moved towards the fixed ring 301. The moving blocks 306 slide on the arc surface of the limiting rod 304. The limiting rod 304 can limit the moving blocks 306 and prevent them from being misaligned during the sliding process on the inner wall of the limiting groove 303. Then, the moving blocks 306 also drive the spring 305 to rewind until the locking block 319 slides into the inner wall of the positioning groove 308. The moving plate 307 is made of stainless steel. Stainless steel has high strength and good wear resistance, which can prevent the moving plate 307 from deforming during short-term use.
