Description

Technical Field

[0001] This utility model relates to the field of explosion-proof motor technology, specifically to a motor with explosion-proof function. Background Technology

[0002] Explosion-proof motors are a type of motor that can be used in flammable and explosive environments without generating electrical sparks during operation. They are primarily used in coal mines, oil and gas, petrochemical, and chemical industries. They are also widely used in textiles, metallurgy, urban gas, transportation, grain and oil processing, papermaking, and pharmaceuticals. However, currently available explosion-proof motors typically use sealable end caps on their terminals to prevent explosions caused by electrical sparks generated when the terminals are energized. These end caps are then sealed with multiple screws. This method is cumbersome, requiring personnel to tighten and loosen multiple screws for sealing or wiring, making the process tedious. Therefore, this paper proposes an explosion-proof motor to address these issues. Utility Model Content

[0003] To solve the problems mentioned above, the technical solution adopted by this utility model is: a motor with explosion-proof function, comprising: a motor body, a terminal block provided on one side of the top of the motor body, a limit ring seat slidably sleeved on the outer circumference of the upper end of the terminal block, a top cover provided on the top of the terminal block, a connecting rod provided at the bottom of the top cover, a locking hole provided on the outer side of the lower end of the connecting rod, a connecting groove provided on the top of the terminal block facing the connecting rod, a rectangular groove provided inside the upper end of the terminal block on the side of the connecting groove, and a lock head slidably connected inside the rectangular groove.

[0004] As a preferred embodiment of this utility model, the inner wall of the upper end of the limiting ring seat is an inclined surface, the end of the lock head facing the inclined surface is a sloping structure, and the end of the lock head facing the lock hole is an arc-shaped structure.

[0005] As a preferred embodiment of this utility model, a first magnet is fixedly disposed at one end of the rectangular groove, and a second magnet is fixedly connected to one end of the lock head located inside the rectangular groove, with the first magnet magnetically connected to the second magnet.

[0006] As a preferred technical solution of this utility model, a sealing gasket is provided in the middle of the bottom end of the top cover, and a bearing ring is fixedly connected to the terminal block below the limiting ring seat on the outer side. A spring is sleeved between the limiting ring seat and the bearing ring on the terminal block.

[0007] As a preferred embodiment of this utility model, a terminal block is provided inside the upper end of the terminal block, and a tube seat is provided on the side of the terminal block below the bearing ring.

[0008] As a preferred embodiment of this utility model, a rubber plug is fitted inside one end of the tube seat, and a gasket is provided inside the tube seat at one end of the rubber plug.

[0009] As a preferred embodiment of this utility model, the tube seat is internally threaded to one end of the washer and has an end sleeve. An L-shaped rod is fixedly connected to the outside of the end sleeve, and a screw rod is threaded to one end of the L-shaped rod opposite the tube seat.

[0010] As a preferred embodiment of this utility model, a wire is connected through the inside of the tube seat, and the wire is connected to the terminal block via an electrical wire.

[0011] As a preferred embodiment of this utility model, four docking rods and four lock heads are provided, the lock heads are located in lock holes that match, and an end cap is installed at the tail of the motor body.

[0012] This utility model has the following advantages: The top cover and the terminal block are assembled by a butt joint, which facilitates quick disassembly and assembly. After the top cover and the terminal block are spliced, the limiting ring can push the lock head, allowing the lock head to be inserted into the lock hole, thereby quickly completing the sealed connection between the top cover and the terminal block. The limiting ring can prevent the lock head from moving arbitrarily, ensuring the stability of the connection between the top cover and the terminal block. This effectively ensures that the motor will not generate electrical sparks at the terminal block and that they will not splash to the outside, thereby improving the explosion-proof effect of the motor.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] Please refer to the following: Figures 1-3 This utility model discloses an explosion-proof motor, comprising: a motor body 1, a terminal block 2 on one side of the top of the motor body 1, a limit ring seat 3 slidably sleeved on the outer side of the upper circumference of the terminal block 2, a top cover 4 on the top of the terminal block 2, a connecting rod 5 on the bottom of the top cover 4, a locking hole 6 on the outer side of the lower end of the connecting rod 5, a connecting groove 7 on the side of the top of the terminal block 2 facing the connecting rod 5, a rectangular groove 8 on the inner side of the upper end of the terminal block 2 located in the connecting groove 7, and a lock head 9 slidably connected inside the rectangular groove 8.

[0021] Combination Figure 2 and Figure 3 As shown, the upper inner wall of the limiting ring seat 3 is inclined, the end of the lock head 9 facing the inclined surface is a sloping structure, and the end of the lock head 9 facing the lock hole 6 is an arc-shaped structure. A first magnet 10 is fixedly installed at one end of the rectangular groove 8, and a second magnet 11 is fixedly connected to the end of the lock head 9 located inside the rectangular groove 8. The first magnet 10 is magnetically connected to the second magnet 11. A sealing gasket 12 is provided in the middle of the bottom end of the top cover 4. A bearing ring 13 is fixedly connected to the terminal block 2 located below the limiting ring seat 3 on the outer side. A spring 14 is sleeved between the terminal block 2 and the limiting ring seat 3 and the bearing ring 13. With the cooperation of the first magnet 10 and the second magnet 11, when the lock head 9 is not pushed by the limiting ring seat 3, it can approach each other under the attraction of the magnets, thus making it easier for the lock head 9 to be pulled out of the lock hole 6.

[0022] The terminal block 2 has a terminal post 15 inside its upper end. A tube seat 16 is located on one side of the terminal block 2 below the bearing ring 13. A rubber plug 17 is fitted inside one end of the tube seat 16. A washer 18 is installed inside the tube seat 16 at the end of the rubber plug 17. An end sleeve 19 is threadedly connected inside the tube seat 16 at the end of the washer 18. An L-shaped rod 20 is fixedly connected to the outside of the end sleeve 19. A screw rod 21 is threadedly connected to the end of the L-shaped rod 20 opposite the tube seat 16. A wire 22 is connected through the tube seat 16. The wire 22 is connected to the terminal post 15 through an electrical wire. There are four connecting rods 5 and four lock heads 9. The lock heads 9 are located in lock holes 6. An end cover 23 is installed at the tail of the motor body 1. Simply tighten the threaded connection sleeve 19 at the end of the tube seat 16 to push the rubber plug 17 to squeeze and seal the wire 22 inside the tube seat 16, thereby ensuring the sealing of the inside of the high-voltage terminal 2, preventing electric sparks from being generated at the motor terminal and splashing to the outside, thus improving the explosion-proof effect of the motor. Furthermore, by tightening the screw rod 21, the sleeve 19 can be prevented from rotating arbitrarily.

[0023] Specifically, when using this utility model, the end of the wire 22 is first passed through the inside of the end sleeve 19, then through the rubber plug 17, and finally through the tube seat 16 to the inside of the terminal block 2. Then, the end of the wire 22 can be connected to the corresponding terminal block 15. Then, just press down on the limiting ring seat 3 to compress the spring 14, so that the inner wall of the limiting ring seat 3 is away from the lock head 9. Then, the lock head 9 is attracted to the first magnet 10 by the moving magnetic force of the second magnet 11, so that the lock head 9 is retracted into the rectangular groove 8. Then, the other hand can pick up the top cover 4, align the docking rod 5 on the top cover 4 with the docking groove 7 and keep pressing down. Then stop pressing the limiting ring seat 3, so that it rises under the upward elastic force of the spring 14. Then, the limiting ring seat 3 can push the lock head 9, so that the lock head 9 is inserted into the lock hole 6, so that the top cover 4 and the terminal block 2 can be sealed quickly. The same operation can quickly remove the top cover 4.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
