For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Combine the following Figures 1 to 3 , describing a diaphragm pump with installation and disassembly tools in an embodiment of the utility model.

[0028] A diaphragm pump with an installation and disassembly tool comprises a diaphragm pump body 1, a mounting groove 2 recessed inwardly is provided at the bottom of the diaphragm pump body 2, a mounting rod 3 and a disassembly rod 4 are provided in the mounting groove 2, a flap 21 is hingedly connected to the bottom wall of the mounting groove 2, and the flap 21 is movable to open or close the mounting groove 2;

[0029] The mounting rod 3 includes a mounting vertical portion 31 and a mounting pressing portion 32. The end of the mounting vertical portion 31 is vertically connected to the mounting pressing portion 32. The mounting pressing portion 32 is used to limit the range of movement of the sealing ring.

[0030] The disassembly rod 4 includes a disassembly vertical portion 41 and a disassembly stripping portion 42 . The end of the disassembly vertical portion 41 is fixedly connected to the disassembly stripping portion 42 . The disassembly stripping portion 42 is used to strip or press the sealing ring.

[0031] In the present invention, a diaphragm pump with an installation and disassembly tool is provided. By opening the flip cover 21, a worker can quickly and conveniently take out or place the installation rod 3 and the disassembly rod 4, thereby improving the user experience.

[0032] The staff holds the disassembly vertical part 41 of the disassembly rod 4, extends the disassembly stripping part 42 into the isolation pump, and by stirring the disassembly vertical part 41, the disassembly stripping part 42 can remove the sealing ring in the diaphragm pump, and then pulls out the disassembly stripping part 42 to complete the disassembly of the sealing ring.

[0033] Next, the staff member holds the installation rod 3 and extends the installation pressing part 32 into the inner wall of the diaphragm pump, and the installation pressing part 32 extends into the inner groove of the sleeve in the diaphragm pump; the new sealing ring is placed in the diaphragm pump, and the installation pressing part 32 can limit the range of movement of the sealing ring to prevent the sealing ring from crossing the corresponding inner groove of the sleeve and falling to the bottom of the diaphragm pump. Finally, the disassembly and stripping part 42 is extended into the isolation pump, and the side wall of the disassembly and stripping part 42 can press the sealing ring, so that the sealing ring fits tightly with the inner groove of the sleeve in the diaphragm pump, thereby completing the installation of the sealing ring.

[0034] This solution can quickly replace the old sealing ring in the diaphragm pump and install a new sealing ring in the diaphragm pump by cooperating with the installation rod 3 and the disassembly rod 4, thereby solving the problem that the shaft space in the traditional diaphragm pump is small and it is difficult to replace the sealing ring manually.

[0035] The disassembly and peeling portion 42 includes a connecting section 43 and a hook section 44 , the connecting section 43 connects the disassembly vertical portion 41 and the hook section 44 , one end of the connecting section 43 is smoothly connected to the disassembly vertical portion 41 , and the other end of the connecting section 43 is smoothly connected to the hook section 44 .

[0036] Among them, the hook section 44 can extend into the sealing ring and the inner groove of the diaphragm pump sleeve. When the vertical part 41 is disassembled by jumping, the hook section 44 can hook the sealing ring outward, so that one end of the sealing ring is hung on the hook section 44, and then the vertical part 41 is pulled outward to be disassembled, so that the entire sealing ring can be completely separated from the diaphragm pump, completing the disassembly of the sealing ring.

[0037] One end of the connecting section 43 is smoothly connected to the disassembly vertical portion 41 , and the other end of the connecting section 43 is smoothly connected to the hook section 44 , so that the disassembly rod 4 has fewer edges and corners, which can improve the user's experience.

[0038] The end of the hook section 44 is away from the disassembly vertical portion 41 .

[0039] In order to better remove the sealing ring, this solution limits the bending direction of the hook section 44, so that the end of the hook section 44 is away from the disassembly vertical portion 41, which not only ensures that the end of the hook section 44 can extend into the sealing ring and the inner groove of the diaphragm pump sleeve, thereby completing the work of removing the sealing ring; it also ensures that the outer side of the side wall of the hook section 44 is lifted up, thereby abutting against the new sealing ring, ensuring that the sealing ring is tightly fitted with the inner groove of the sleeve in the diaphragm pump.

[0040] The end of the installation pressing portion 32 away from the installation vertical portion 31 is provided with a sharp corner; the end of the disassembly peeling portion 42 away from the disassembly vertical portion 41 is provided with a sharp corner.

[0041] When removing the sealing ring, the sharp corner is inserted into the inner groove of the sealing ring and the diaphragm pump sleeve, and then the removal rod 4 is moved so that the sharp corner can pick out the sealing ring. Then the removal rod 4 is rotated so that the sealing ring can be hung on the stripping and removal part, and the removal rod 4 is pulled upward to complete the removal of the sealing ring.

[0042] When installing the sealing ring, the sharp corner of the installation pressing portion 32 can extend into the inner groove of the sleeve to limit the sealing ring from falling to the bottom of the diaphragm pump, thereby limiting the range of movement of the sealing ring.

[0043] The installation vertical portion 31 and the removal vertical portion 41 are both provided with a telescopic structure.

[0044] It is worth noting that the telescopic structure is a common structure. The telescopic structure is installed on the installation vertical part 31 and the disassembly vertical part 41. When extended, the use range of the installation rod 3 and the disassembly rod 4 of this scheme can be expanded; when shortened, the storage space can be saved.

[0045] A buffer cotton 22 is arranged in the installation groove 2 , and a surface of the buffer cotton 22 is provided with an inwardly recessed groove, and the two grooves are adapted to the installation rod 3 and the disassembly rod 4 .

[0046] Among them, the disassembly and peeling part 42 is provided with a sharp corner. In order to reduce the wear of the sharp corner of the disassembly and peeling part 42, a buffer cotton 22 can be filled in the installation groove 2. The buffer cotton 22 effectively plays a shockproof effect, which not only reduces the friction between the sharp corner and the inner wall of the installation groove 2, causing the sharp corner to appear wear, but also can reduce noise and improve the user experience.

[0047] Example 2

[0048] This embodiment is basically the same as the embodiment, except that: the disassembly and peeling portion 42 includes a first inclined section 45 and a second inclined section 46, one end of the first inclined section 45 is connected to the second inclined section 46, the other end of the first inclined section 45 is connected to the disassembly vertical portion 41, the first inclined section 45 and the disassembly vertical portion 41 form a first inclined angle, and the first inclined section 45 and the second inclined section 46 form a second inclined angle.

[0049] The first inclination angle is 135°. Under this setting, the disassembly and peeling portion 42 can better extend into the sealing ring and the inner groove of the sleeve of the diaphragm pump, thereby ensuring that the disassembly and peeling portion 42 can remove the sealing ring in the inner groove of the sleeve of the diaphragm pump.

[0050] At this time, the second inclination angle is 135°, so that the second inclined section 46 is parallel to the disassembly vertical portion 41, so that the second inclined portion can abut against the new sealing ring to ensure that the sealing ring fits tightly with the inner groove of the sleeve in the diaphragm pump.

[0051] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
