When using the metering pump, the connection between the pump body 2 and the external conduit is in close contact with the upper surface of the mounting base 1. The profiled groove 5 improves the placement stability and installation convenience of the pump body 2. The difference in length between the mounting base 1 and the pump body 2 provides a supporting force for the pump body 2 and the external conduit, improving the connection stability between the metering pump and the external conduit during use. Movable wheels 8 are provided at the lower end of the mounting base 1, and the movable wheels 8 improve the convenience of moving the metering pump. A storage groove 12 is provided on the lower surface of the mounting base 1, and the rollers of the movable wheels 8 are located inside the storage groove 12. The storage groove 12 reduces the contact area between the movable wheels 8 and the outside world, reducing the risk of damage to the movable wheels 8.

[0022] Two positioning rods 6 are rotatably connected to the surface of the mounting base 1. When using the metering pump, the positioning rods 6 are in close contact with the surface where the metering pump is placed. The positioning rods 6 provide a placement balance force for the metering pump and the conditions for carrying and lifting the metering pump. A reinforcement mechanism 7 is provided between the positioning rods 6 and the mounting base 1. The reinforcement mechanism 7 is composed of two pin holes 9 and two pins 10. The pins 10 penetrate through the positioning rods 6 and are slidably connected to the positioning rods 6. The reinforcement mechanism 7 improves the stability of the positioning rods 6 when in use. A connecting plate 11 is provided at the end of the pin 10 away from the positioning rod 6, and the connecting plate 11 is fixedly connected to the two pins 10. The connecting plate 11 improves the convenience of using the pins 10. A profiled section 13 is provided at the end of the pin 10 close to the mounting base 1. When using the metering pump, the inner wall of the profiled section 13 is in close contact with the movable wheels 8.

The pins 10 block and lock the movable wheels 8 when using the metering pump, improving the stability of the metering pump during use. The profiled section 13 increases the contact area between the pins 10 and the rollers of the movable wheels 8, improving the effect of the pins 10.

[0023] A mounting block 3 is fixedly connected to the upper end of the pump body 2. A telescopic limiting member 4 is fixedly connected inside the mounting block 3. The telescopic end of the telescopic limiting member 4 penetrates through the front and rear surfaces of the mounting block 3.

The telescopic limiting member 4 is composed of a mounting shell 14 and a clamping plate 15. The clamping plate 15 is slidably connected to the mounting shell 14. When using the metering pump, the clamping plate 15 is located inside the mounting shell 14. The telescopic limiting member 4 is used to improve the stability of the positioning rod 6 in the upright state. A protective pad 16 is arranged inside the clamping groove of the clamping plate 15. The protective pad 16 is in close contact with the positioning rod 6. The protective pad 16 is made of rubber, which reduces the wear effect between the clamping plate 15 and the positioning rod 6 and improves the clamping effect between the clamping plate 15 and the positioning rod 6.

[0024] Working principle: When using the metering pump, pull the connecting plate 11 to pull out the pin 10 from the pin hole 9, and then lift the clamping plate 15 to separate the positioning rod 6 from the clamping plate 15. The mounting shell 14 is used to accommodate the clamping plate 15. Therefore, the length, width, and height of the internal space of the mounting shell 14 are all greater than the length, width, and height of the clamping plate 15. Therefore, a lifting space is reserved for the clamping plate 15 to improve the convenience of separating and clamping the positioning rod 6 from the clamping plate 15. Then place the positioning rod 6 flat at the place where the metering pump is placed, and use the pin 10 to block and lock the moving wheel 8. Note that the clamping plate 15 is pushed into the mounting shell 14. At this time, the conduit can be connected to the metering pump. When carrying the metering pump, still first release the restriction of the pin 10 on the positioning rod 6, and then reset the positioning rod 6. When lifting the positioning rod 6, it is necessary to first pull out the clamping plate 15, and then use the method of manually lifting the clamping plate 15 to clamp the clamping plate 15 with the positioning rod 6 in the upright state, and then use the pin 10 to fix the positioning rod 6. At this time, two ways of carrying the metering pump are provided. The first way is to directly push the metering pump, and the second way is to lift or lift the metering pump through the positioning rod 6.
