[0002] Pneumatic diaphragm pump is a fluid conveying equipment, which is widely used in the manufacturing of wet electronic chemicals. It uses compressed air as the power source, and the diaphragm is generally made of high-purity PFA and PTFE. It is used to convey high-purity wet electronic chemicals, such as electronic grade sulfuric acid, ammonia water, hydrochloric acid, etc.

[0003] Due to actual production and process requirements, some diaphragm pumps need to run 24 hours a day, which makes the diaphragm pump diaphragm easy to rupture and damage, and requires regular maintenance and replacement. Traditional diaphragm pumps only need to use an adjustable wrench to unscrew the gland to replace the diaphragm, but the pneumatic diaphragm pump of the YAMADA brand cannot be disassembled using an adjustable wrench due to the radial protrusion of the gland. If non-special traditional tools such as pipe wrenches are used, the gland will be damaged. Traditional tools cannot meet the requirements of disassembly of the diaphragm gland of the YAMADA pneumatic diaphragm pump. For this reason, we propose a pneumatic diaphragm pump diaphragm gland quick disassembly wrench for wet electronic chemicals. Utility Model Content

[0022] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0023] Embodiment:

[0024] like Figure 1-4 As shown, the utility model provides a pneumatic diaphragm pump diaphragm gland quick disassembly wrench for wet electronic chemicals, comprising a wrench body 1, a sleeve limiting hole 2 is opened at the end of the wrench body 1, and a disassembly sleeve 3 is sleeved inside the sleeve limiting hole 2, the disassembly sleeve 3 comprises a sleeve body 31 sleeved inside the sleeve limiting hole 2 and limited by the sleeve limiting hole 2, sleeve limiting sheets 32 formed on both sides of the sleeve body 31 to limit the relative position of the sleeve body 31 and the sleeve limiting hole 2, the sleeve body 31 is clamped in the sleeve limiting hole 2 under the cooperation and limitation of the sleeve limiting sheet 32 ​​and the sleeve limiting hole 2, the disassembly sleeve 3 also comprises a sleeve Rotation limiting block 33, the sleeve rotation limiting block 33 is located on both sides of the sleeve body 31, the thickness of the sleeve rotation limiting block 33 is consistent with the thickness of the wrench body 1, and a notch matching the sleeve rotation limiting block 33 is opened at the edge of the sleeve limiting hole 2. The notch and the sleeve rotation limiting block 33 form a nested fixed structure. The diameter of the sleeve limiting piece 32 is larger than the diameter of the sleeve limiting hole 2. The sleeve limiting piece 32 fits the surface of the wrench body 1. After the sleeve body 31 is embedded in the sleeve limiting hole 2, the sleeve limiting piece 32 can limit the sleeve body 31 from escaping from the inside of the sleeve limiting hole 2. At the same time, one side of the sleeve limiting piece 32 is the working surface of the device.

[0025] The sleeve body 31 is sleeved on the end of the diaphragm gland of the pneumatic diaphragm pump, and the wrench body 1 is pressed down. The wrench body 1 can drive the sleeve body 31 in the disassembly sleeve 3 to rotate through the sleeve limiting hole 2, and the sleeve body 31 completes the disassembly of the diaphragm gland of the pneumatic diaphragm pump.

[0026] There are several groups of disassembly sleeves 3, and the size of the sleeve body 31 in each group of disassembly sleeves 3 increases from small to large. According to the different specifications of the diaphragm gland of the pneumatic diaphragm pump, disassembly sleeves 3 of different specifications can be selected to improve the adaptability and versatility of the device when used.

[0027] A disassembly sleeve limiting member 4 is provided on the back of the wrench body 1. The disassembly sleeve limiting member 4 includes a slide groove 41, a slider 42 and a sleeve limiting block 43. The slide groove 41 is provided on the wrench body 1 at the edge of the sleeve limiting hole 2 and is connected to the sleeve limiting hole 2. The slider 42 is sleeved in the slide groove 41. The end of the slider 42 is provided with a sleeve limiting block 43 that can be embedded in the sleeve body 31. A notch that cooperates with the sleeve limiting block 43 is provided at the edge of the sleeve body 31. The width of the notch is greater than the width of the sleeve limiting block 43, and the length of the notch is shorter than the length of the sleeve limiting block 43. After the sleeve limiting block 43 is embedded in the notch at the edge of the sleeve body 31, the sleeve limiting block 43 can limit the sleeve body 31 to prevent the sleeve body 31 from escaping from the inside of the sleeve limiting hole 2, thereby ensuring the stability of the disassembly sleeve 3 set inside the sleeve limiting hole 2.

[0028] The disassembly sleeve limiting member 4 further includes two groups of magnets 44, which are respectively arranged at the opposite positions of the slide groove 41 and the slider 42. The two groups of magnets 44 have the same magnetic poles. Under the mutual repulsion of the two groups of magnets 44 at the same magnetic poles, the slider 42 is pushed to slide inside the slide groove 41, so that the slider 42 always has a tendency to move laterally inside the slide groove 41, so that the slider 42 can continuously push the sleeve limiting block 43, so that the sleeve limiting block 43 can be stably embedded in the notch at the edge of the sleeve body 31;

[0029] First, pull the slider 42 horizontally to make it move horizontally along the slide groove 41, and the sleeve limiting block 43 at the end of the slider 42 is retracted into the slide groove 41. When the sleeve body 31 is embedded in the sleeve limiting hole 2, the restriction on the slider 42 is released. Under the magnetic repulsion of the magnet 44, the slider 42 pushes the sleeve limiting block 43 to be embedded in the notch at the edge of the sleeve body 31, thereby completing the restriction on the sleeve body 31.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
