[0002] Explosion-proof motors are motors that can be used in flammable and explosive places. They do not generate sparks during operation. Explosion-proof motors are mainly used in coal mines, oil and gas, petrochemical and chemical industries. They are also widely used in textiles, metallurgy, city gas, transportation, grain and oil processing, papermaking, medicine and other departments.

[0003] Patent No.: CN98997810U, proposes an explosion-proof motor casing that is easy to install. By using a rotatable plug-in plate structure, the plug-in plate can be rotated before installation, so that the side plate can be close to the shell, and through the movement and traction of the tension spring, the plug-in plate can pass through the limit block, so that the side plate is connected to the shell, and the limit block is rotated to limit the slot, thereby preventing the plug-in plate from moving after installation, facilitating the installation of the casing, and can complete quick installation work without tools, which is very convenient.

[0004] However, during the implementation of the solution, the device limits the slot and fixes the plug-in board by rotating the limit block, and since the device has multiple groups of limit blocks, the staff needs to rotate the limit blocks multiple times, which is too cumbersome and inconvenient for the staff to use. Therefore, a new explosion-proof single-phase motor casing is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0024] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0025] See also Figure 1-5 The utility model provides a technical solution: a new explosion-proof single-phase motor casing, including a base 1, a motor housing 2 is fixedly connected to the surface of the base 1, a fixing plate 4 is fixedly connected to the surface of the motor housing 2, a ring plate 3 is rotatably connected to the surface of the fixing plate 4, a card slot 12 is provided on the surface of the fixing plate 4, a card block 14 is slidably connected to the inside of the fixing plate 4, a connecting rod 13 is fixedly connected to the surface of the card block 14, the surface of the connecting rod 13 is slidably connected to the inside of the fixing plate 4, and the end of the connecting rod 13 away from the card block 14 is fixedly connected to the fixing plate 4, a side plate 5 is provided on one side of the fixing plate 4, a card rod 16 is fixedly connected to the surface of the side plate 5, a limiting groove 17 is provided on the surface of the card rod 16, and the position of the limiting groove 17 corresponds to the position of the card block 14, a spring 2 15 is fixedly connected to the inside of the fixing plate 4, and the end of the spring 2 15 away from the fixing plate 4 is fixedly connected to the card block 14.

[0026] When the ring plate 3 is rotated, the ring plate 3 drives the connecting rod 13 to move, and the connecting rod 13 drives the block 14 to move, so that the block 14 slides inside the fixed plate 4, and the block 14 moves to squeeze the spring 2 15. At this time, the side plate 5 moves toward the fixed plate 4, so that the block 16 is inserted into the inside of the card slot 12, and the ring plate 3 is no longer rotated. At this time, under the elastic force of the spring 2 15, the block 14 drives the connecting rod 13 and the ring plate 3 to rotate, so that the block 14 is inserted into the inside of the limit groove 17, and then the side plate 5 is fixed by rotating the ring plate 3, which is convenient for the staff to fix and install the side plate 5, and at the same time avoids the staff from fixing it through multiple sets of fixing devices, reducing cumbersome steps and alleviating the labor burden of the staff.

[0027] A fixing block 8 is fixedly connected to the surface of the motor housing 2, and a groove 9 is opened on the surface of the side plate 5, and the groove 9 is set in two groups. Rubber pads are fixedly connected to the inside of the two grooves 9. When the side plate 5 and the motor housing 2 are fixed, the fixing block 8 is inserted into the inside of the outer ring groove 9 and fits tightly to the rubber pad inside the outer ring groove 9 to seal it to prevent water from entering the inside from the connection between the motor housing 2 and the side plate 5, and the motor housing 2 is waterproofed.

[0028] The inside of the motor housing 2 is slidably connected to a sliding plate 7, and the surface of the side plate 5 is fixedly connected to a reinforcing plate 18, and the surface of the reinforcing plate 18 contacts the inner wall of the base 1. When the side plate 5 and the motor housing 2 are fixed, the reinforcing plate 18 is inserted into the inside of the motor housing 2 to further reinforce the connection between the side plate 5 and the motor housing 2 to protect the device.

[0029] The inner wall of the motor housing 2 is provided with a slide groove 6, and the slide groove 6 is arranged in a bent shape. The surface of the reinforcement plate 18 is provided with a limiting groove 19, and the limiting groove 19 is arranged at an angle. The inner wall of the limiting groove 19 is slidably connected with a push rod 20, and the position of the push rod 20 corresponds to the position of the slide groove 6.

[0030] When the reinforcing plate 18 is inserted into the motor housing 2, the push rod 20 is inserted into the slide groove 6. When the push rod 20 moves to the bending part of the slide groove 6, and because the limiting groove 19 is inclined, the push rod 20 slides along the inner wall of the slide groove 6.

[0031] A sliding rod 10 is fixedly connected to the surface of the sliding plate 7, and the surface of the sliding rod 10 is inclined. A spring 11 is fixedly connected to the surface of the sliding plate 7, and one end of the spring 11 away from the sliding plate 7 is fixedly connected to the inside of the motor housing 2.

[0032] When the device is fixed, the push rod 20 moves to the bottom of the bend of the slide groove 6, and due to the setting of the inclined surface of the sliding rod 10, the push rod 20 squeezes the inclined surface of the sliding rod 10, so that the sliding rod 10 pushes the sliding plate 7, causing the sliding plate 7 to slide out from the inside of the motor housing 2 and insert into the inside of the inner ring groove 9, thereby performing a secondary seal on the device. At the same time, the sliding plate 7 is inserted into the inside of the inner ring groove 9, further fixing the side plate 5 and the motor housing 2, thereby increasing the protective effect of the device.

[0033] Working principle: the ring plate 3 is rotated, and the ring plate 3 drives the connecting rod 13 and the block 14 to move, so that the block 14 slides inside the fixed plate 4, and at the same time, the block 14 moves to squeeze the spring 2 15. At this time, the side plate 5 moves toward the fixed plate 4, so that the block 16 is inserted into the inside of the card slot 12, and the ring plate 3 is no longer rotated. At this time, under the elastic force of the spring 2 15, the block 14 drives the connecting rod 13 and the ring plate 3 to rotate, so that the block 14 is inserted into the inside of the limit groove 17, and then the side plate 5 is fixed by rotating the ring plate 3.

[0034] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
