It uses compressed air as a power source and can pump out all kinds of corrosive liquids, liquids containing particles, high-viscosity, volatile, flammable, and highly toxic liquids.

[0003] The inventor discovered in his daily work that the flow rate of liquid is difficult to control and adjust according to needs during use. In order to solve the problem of difficult flow rate adjustment and control, the existing technology is to purchase pumps of different sizes, but this increases the user's economic expenditure, consumes a lot of time, and makes the equipment difficult to use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where liquid flow is difficult to adjust and control, and to propose a pneumatic diaphragm pump.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a pneumatic diaphragm pump, including a base and an adjusting device, wherein an organic body is disposed on the surface of the base, and an outlet is provided on one side of the organic body. The adjusting device is disposed on the surface of the organic body, and the adjusting device includes a threaded rod, which is rotatably connected to the organic body. The side of the threaded rod away from the organic body passes through the organic body and is fixedly connected to a rotating block. By setting the adjusting device, it is convenient to adjust and control the flow rate of the equipment, thereby increasing the stability of the equipment and facilitating its use.

[0006] Preferably, the surface of the machine body has a hole, and a flow limiting plate is slidably connected to the inner wall of the hole. By setting the flow limiting plate, it is easy to control the flow rate, which increases the stability of the equipment and reduces the difficulty of operating the equipment.

[0007] Preferably, a waterproof sleeve is fixedly connected to the side of the machine body near the flow limiting plate. The waterproof sleeve is fitted onto the flow limiting plate. By setting the waterproof sleeve, during use, the waterproof sleeve adheres to the machine body to block the sliding part of the flow limiting plate and reduce the leakage of liquid.

[0008] Preferably, a movable block is fixedly connected to one side of the flow limiting plate. The movable block has a threaded hole on its surface, and the threaded rod is threadedly connected to the threaded hole on the surface of the movable block. By setting the threaded rod, the threaded rod drives the flow limiting plate to slide during use, which increases the stability of the equipment and reduces the difficulty of operating the equipment.

[0009] Preferably, the surface of the base is provided with a combination device, the combination device including a mounting block, the mounting block being fixedly connected to the base, the surface of the mounting block having a groove, and a clamping plate being slidably connected to the inner wall of the groove on the surface of the mounting block. By setting the combination device, it is convenient to quickly install and disassemble the machine body, making it convenient for users to maintain.

[0010] Preferably, a square block is fixedly connected to one side of the clamping plate. A second hole is formed on the surface of the square block, and a second groove is formed on the surface of the mounting block. A slider is slidably connected to the inner wall of the second groove on the surface of the mounting block. A plug is fixedly connected to the surface of the slider. The plug is inserted into the second hole on the surface of the square block. By setting the plug, when in use, the plug is inserted into the square block, which facilitates the storage of the clamping plate, increases the stability of the equipment, and reduces the difficulty of operating the equipment.

[0011] Preferably, a baffle is fixedly connected to the side of the machine body near the base, the baffle is inserted into the mounting block, a fixing spring is fixedly connected to one side of the clamping plate, and the side of the fixing spring away from the clamping plate is fixedly connected to the mounting block. By setting the fixing spring, when in use, the fixing spring generates elastic force to push the clamping plate to slide, which increases the ease of use of the equipment and facilitates operation.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting an adjustment device, when the equipment needs to limit the flow, the rotating block is rotated, the rotating block drives the threaded rod, and the threaded rod drives the flow limiting plate to be inserted into the machine body, compressing the space of the machine body and limiting the flow. When the flow needs to be increased, the rotating block is reversed, the rotating block drives the threaded rod to pull out the flow limiting plate, increasing the space in the machine body and increasing the flow. By setting an adjustment device, it is easy to control the flow of the machine body, increasing the stability of the equipment, reducing the difficulty of operating the equipment, and making it convenient for users to adjust according to environmental needs.

[0014] 2. In this utility model, by setting up a combination device, when the machine body needs maintenance, it is time-consuming to disassemble the machine body with tools. However, with this device, pulling the clamping plate away from the baffle causes the square block to abut against the slider. Pressing the slider causes the insertion rod to be inserted into the square block to complete the storage. Then, the machine body can be lifted upwards to remove it. After maintenance, the machine body is placed on the base, the baffle and the mounting block are fitted together, and pulling the slider causes the insertion rod to move away from the square block. At this time, the fixing spring is released and generates elastic force to push the clamping plate against the baffle to complete the positioning. By setting up a combination device, it is easy to assemble and install the equipment, reducing the need for tool assistance, increasing the ease of use of the equipment, and making it easier for users to maintain and use.

By setting the flow limiting plate 31, it is convenient to control the flow rate, which increases the stability of the equipment and reduces the difficulty of operating the equipment.

[0025] Specifically, a waterproof sleeve 32 is fixedly connected to the side of the body 2 near the flow limiting plate 31, and the waterproof sleeve 32 is fitted onto the flow limiting plate 31.

[0026] In this embodiment: by setting a waterproof sleeve 32, when in use, the waterproof sleeve 32 is adhered to the body 2 to block the sliding part of the flow limiting plate 31 and reduce the leakage of liquid.

[0027] Specifically, a movable block 35 is fixedly connected to one side of the flow limiting plate 31. The surface of the movable block 35 is provided with a threaded hole. The threaded rod 34 is threadedly connected to the threaded hole on the surface of the movable block 35. By setting the threaded rod 34, the threaded rod 34 drives the flow limiting plate 31 to slide during use, which increases the stability of the equipment and reduces the difficulty of operating the equipment.

[0028] In this embodiment: the surface of the base 1 is provided with a combination device 4, the combination device 4 includes a mounting block 46, the mounting block 46 is fixedly connected to the base 1, the surface of the mounting block 46 is provided with a groove, and the inner wall of the groove on the surface of the mounting block 46 is slidably connected with a clamping plate 41.

[0029] In this embodiment, the combination device 4 facilitates the quick installation and disassembly of the body 2, making it convenient for users to maintain.

[0030] Specifically, a square block 43 is fixedly connected to one side of the clamping plate 41. A second hole is opened on the surface of the square block 43. A second groove is opened on the surface of the mounting block 46. A slider 44 is slidably connected to the inner wall of the second groove on the surface of the mounting block 46. A plug rod 45 is fixedly connected to the surface of the slider 44. The plug rod 45 is inserted into the second hole on the surface of the square block 43. By setting the plug rod 45, when in use, the plug rod 45 is inserted into the square block 43, which makes it easy to store the clamping plate 41, increases the stability of the equipment, and reduces the difficulty of operating the equipment.

[0031] Specifically, a baffle 47 is fixedly connected to the side of the body 2 near the base 1. The baffle 47 is inserted into the mounting block 46.

[0033] Working principle: By setting the adjustment device 3, when the equipment needs to limit the flow, the rotating block 33 is rotated. The rotating block 33 drives the threaded rod 34, which in turn drives the flow-limiting plate 31 to insert into the machine body 2, compressing the space in the machine body 2 and limiting the flow. When the flow needs to be increased, the rotating block 33 is reversed. The rotating block 33 drives the threaded rod 34 to pull out the flow-limiting plate 31, increasing the space in the machine body 2 and increasing the flow. By setting the adjustment device 3, the flow of the machine body 2 can be easily controlled, increasing the stability of the equipment, reducing the difficulty of operation, and allowing users to adjust according to environmental needs. When the machine body 2 needs maintenance, the combined device 4 allows the machine body 2 to be disassembled using tools. For a significant amount of time, this device involves pulling the clamping plate 41 away from the baffle 47. At this time, the square block 43 and the slider 44 abut against each other. Pressing the slider 44 causes the insertion rod 45 to be inserted into the square block 43 to complete the storage. Then, the machine body 2 can be lifted upwards to remove it. After maintenance, the machine body 2 is placed on the base 1, with the baffle 47 and the mounting block 46 fitted together. Pulling the slider 44 causes the insertion rod 45 to move away from the square block 43. At this time, the fixing spring 42 loses its restraint and generates elastic force to push the clamping plate 41 and the baffle 47 to abut against each other to complete the positioning. By setting the combination device 4, it is easy to combine and install the equipment, reducing the need for tool assistance, increasing the ease of use of the equipment, and making it convenient for users to maintain and use.
