[0002] According to the published patent CN219432578U, a valve motor spindle mounting structure includes a mounting base. A fixing mechanism is provided on the top side of the mounting base, and a connection is provided on the inner side of the mounting base. Through the connection mechanism, with the cooperation of a retaining bracket, a first connecting base is connected to the valve stem. Then, a second connecting base is fastened to the top side of the first connecting base. Positioning is achieved through a cross-shaped positioning block and a cross-shaped positioning groove, so that the cross-shaped positioning block is fastened in the cross-shaped positioning groove. At this time, an adjusting rod is inserted and installed inside the second connecting base. Similarly, with the cooperation of the retaining bracket, the second connecting base is connected to the rotating shaft, thereby realizing the function of connecting the rotating shaft and the valve stem. The installation process is simple and can withstand a large load, and is not easily deformed. However, it still has the following shortcomings:

[0003] While the aforementioned equipment allows for rapid installation, it requires additional tools. This can lead to difficulties in installation and disassembly if the user forgets or lacks the necessary tools, resulting in poor operational flexibility. Therefore, we propose an AC asynchronous motor mounting device for valves. Utility Model Content

Through the installation mechanism and the protective mechanism, it solves the problem that although it can be installed quickly, it requires additional tools for the installation operation. When the user is inconvenient or forgets to bring the corresponding tools, it will be difficult to install and disassemble, resulting in poor operational flexibility.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an AC asynchronous motor mounting device for valves, including a valve tube, a plurality of limiting blocks are fixedly connected to the outer wall of the valve tube, a sliding rod is fixedly connected to the outer wall of each of the limiting blocks, and an installation mechanism is provided on the inner wall of the valve tube.

[0007] The installation mechanism includes a rotating rod, the outer wall of which is rotatably connected to the inner wall of the valve pipe. A water-blocking ball is fixedly connected to the bottom outer wall of the rotating rod. A mating groove is formed on the inner wall of the rotating rod. A connecting pipe is fixedly connected to the outer wall of the valve pipe. A mounting base is fixedly connected to the top outer wall of the connecting pipe. A worm gear is rotatably connected to the inner wall of the mounting base. A knob is fixedly connected to the outer wall of the worm gear. A connecting rod is rotatably connected to the inner wall of the mounting base. A worm wheel is fixedly connected to the outer wall of the connecting rod. The outer wall of the worm wheel meshes with the outer wall of the worm gear. Several gears are fixedly connected to the outer wall of the connecting rod. The outer wall of the mounting base is rotatably connected to several coupling discs, and the outer walls of the coupling discs are fixedly connected to gears II. The outer walls of the gears II mesh with the outer walls of the gears. The inner walls of the coupling discs are rotatably connected to several coupling rods, and the inner walls of the coupling rods are rotatably connected to insert plates. The inner wall of the mounting base has a mounting groove, and the inner wall of the mounting groove is slidably connected to a mounting block. The inner wall of the mounting block has several fixing grooves, and the inner walls of the fixing grooves are slidably connected to the outer walls of the insert plates. The inner wall of the mounting block is fixedly connected to a motor, and the bottom output shaft of the motor is fixedly connected to a transmission rod via a coupling.

[0008] Furthermore, a protective mechanism is provided on the outer wall of several of the slide rods, the protective mechanism including a sliding ring, the inner wall of the sliding ring being slidably connected to the outer wall of several slide rods.

[0009] Furthermore, a sliding ring is slidably connected to the outer wall of several of the sliding rods, and a protective shell is fixedly connected to the top outer wall of the sliding ring.

[0010] Furthermore, the outer wall of the protective shell is fixedly connected with several fixing blocks, and each of the fixing blocks has a fixing groove inside.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates insert plates. A knob drives a worm gear to rotate, which in turn drives a worm wheel to rotate. The worm wheel then drives a connecting rod to rotate, which in turn drives several gears to rotate. Each of these gears drives a second gear to rotate, which in turn drives a coupling disc to rotate. The coupling disc then drives several connecting rods to shift and rotate, which in turn drives the insert plates to shift. The insert plates then move away from each other and detach from the fixing slots, thus no longer restricting the movement of the mounting block. Subsequently, the motor and mounting block can be directly removed from the mounting slots and separated. This allows for quick disassembly and installation of the motor without the need for additional tools, ensuring that the motor is securely held in the required position, resulting in high efficiency and reliability.

[0017] 2. This utility model features a protective shell. The protective shell and the second protective shell work together to protect the motor. To remove the protective state and replace the motor, several push buttons can be squeezed inward. Each push button will cause the fixing pin to move, and the fixing pin will disengage from the second fixing groove and compress the spring. Then, the sliding ring and the second sliding ring can be pushed to the sides respectively. The sliding ring will cause the protective shell to move, and the second sliding ring will cause the second protective shell to move, thus removing the protective state and exposing the motor to the outside. This provides reliable protection for the installed motor and prevents the motor from being damaged or even destroyed due to direct collision with foreign objects.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0036] One specific application of this embodiment is:

[0037] When the equipment is needed, protective shell 303 and protective shell 206 cooperate to protect motor 218. To remove the protective state and replace motor 218, several push buttons 310 can be squeezed inward. Each push button 310 will cause the fixing pin 309 to move, disengaging it from the fixing groove 205 and compressing spring 311. Then, sliding ring 301 and sliding ring 202 can be pushed to the sides. Sliding ring 301 will cause protective shell 303 to move, and sliding ring 202 will cause protective shell 206 to move, removing the protective state and exposing motor 218 to the outside. To replace motor 218, knob 207 can be turned counterclockwise.

Several gears 210 rotate, and each of the gears 210 drives gear 212 to rotate. Gear 212 drives coupling disc 211 to rotate, and coupling disc 211 drives several coupling rods 213 to move and rotate. Each coupling rod 213 drives insertion plate 214 to move. The insertion plates 214 move away from each other and detach from the fixing groove 217 so as not to restrict the displacement of mounting block 216. Then, the motor 218 and mounting block 216 can be directly removed upward from the mounting groove 215 to separate them. Then, the motor 218 and mounting block 216 to be installed can be operated in reverse order of the above steps. Start the motor 218, and the motor 218 will drive the transmission rod 219 to rotate. The transmission rod 219 will drive the rotating rod 201 to rotate. The rotating rod 201 will drive the water blocking ball 202 to rotate. When the water blocking ball 202 rotates ninety degrees, its internal holes will allow water to flow through the valve pipe 1.
