By the left-right movement of the diaphragm within the pump chamber, liquid medium can be drawn in from the inlet 3 and then out from the outlet 4. One end of the pump body 1, which faces the motor 2, is provided with a connecting disc 5, and a plurality of cutting bars 51 are arranged on one side of the connecting disc 5, which faces the motor 2, in a telescopic manner; a fixed disc 6 is arranged at one end of the motor 2 facing the pump body 1, a plurality of insertion holes 61 are formed in the fixed disc 6 in a penetrating manner, and a locking piece 7 is arranged at one side of the fixed disc 6 facing the motor 2; the slips 51 are inserted into the insertion hole 61 and extended out of the insertion hole 61 to be locked by the locking piece 7. When the motor 2 is required to be connected with the pump body 1, the cutting 51 on the pump body 1 is only required to be inserted into the jack 61 on the motor 2, and then the part of the cutting 51 extending out of the jack 61 is locked by the locking piece 7; when the motor 2 is required to be detached from the pump body 1 for cleaning or maintenance, the locking of the cutting 51 by the connector is released, and then the cutting 51 is taken out of the insertion hole 61.

Referring to fig. 6, in order to facilitate insertion of the cutting 51 into the insertion hole 61, a sliding groove 62 is provided on the fixing plate 6 on a side facing the cutting 51, the cutting 51 is movably provided in the sliding groove 62, and the insertion hole 61 is penetratingly provided in the sliding groove 62. The method of sliding the slips 51 on the sliding grooves 62 and then inserting the slips 51 into the sockets 61 when the slips 51 are aligned with the sockets 61 facilitates alignment of the slips 51 with the sockets 61 without manually aligning the slips 51 one by one with the sockets 61. This scheme is compared in traditional through screw down one by one or dismantle one by one, and is more convenient, is favorable to motor 2 and pump body 1's connection and dismantlement, improves work efficiency.

Referring to fig. 3, specifically, the locking member 7 includes a locking post 71 telescopically provided on a side of the cutting 51 facing the fixed disk 6, the locking post 71 being provided along a center line of the fixed disk 6. When the cutting 51 is inserted into the insertion hole 61 and extends out of the insertion hole 61, the locking post 71 extends outward from the inside of the cutting 51, and then the cutting 51 is disposed to intersect the locking post 71 on a side of the fixing plate 6 away from the connecting plate 5, and at this time, the locking post 71 restricts the position of the cutting 51 to prevent the cutting 51 from being detached from the insertion hole 61.

Referring to fig. 4 and 5, the side of the cutting 51 facing the stop collar 8 is provided with a receiving hole 511, a spring 72 is provided in the receiving hole 511, one end of the spring 72 is fixedly connected with the bottom of the receiving hole 511, the other end of the spring 72 is fixedly connected with a locking post 71, and the locking post 71 movably penetrates into the receiving hole 511. The setting of accommodation hole 511 limits the flexible position of spring 72, prevents that spring 72 from taking place the displacement in flexible in-process, and spring 72 pushes away from accommodation hole 511 with locking post 71 in the direction of keeping away from accommodation hole 511 under the initial condition, and the one end that locking post 71 is close to accommodation hole 511 sets up in accommodation hole 511 inside all the time. When the insert 51 is inserted into the insertion hole 61, the locking post 71 is always disposed in the accommodating hole 511, and when the insert 51 is inserted into the insertion hole 61, the insert 51 is restricted by the limiting of the underwear insertion hole 61 to the locking post 71, and the locking post 71 extends out of the accommodating hole 511.

In order to further limit the locking post 71, a limiting ring 8 is also rotatably arranged on one side of the fixed disc 6 away from the connecting disc 5; a locking hole 81 is formed in one side, facing the locking column 71, of the limiting ring 8, and the locking hole 81 is arranged in an arc shape; the locking post 71 is disposed in an arc shape toward one end of the locking hole 81, and the locking post 71 is movably disposed in the locking hole 81. When the cutting 51 is inserted into the insertion hole 61 and extends out of the insertion hole 61, the locking post 71 on the cutting 51 protrudes from the cutting 51, and then the locking hole 81 on the limiting ring 8 is aligned with the locking post 71 by rotating the limiting ring 8, so that the locking post 71 is arranged in the locking hole 81, thereby facilitating the fixation of the locking post 71, and further, the cutting 51 is better fixed on the fixed disk 6, and the connection of the motor 2 and the pump body 1 is completed. The locking hole 81 and the locking post 71 are both arc-shaped towards one end of the locking hole 81, which is beneficial to enabling the locking post 71 to enter the locking hole 81 when the limiting ring 8 is rotated.

In order to be able to reduce the energy consumption of the diaphragm pump, the motor 2 used is a permanent magnet motor. Because the permanent magnet motor can regulate speed in a variable frequency manner, the synchronism is good, and the energy and the electricity can be saved by 10-50%. In addition, the pump body 1 is also provided with a through groove 11, and the through groove 11 is communicated with the pump body 1 and the outside. The through groove 11 can be used for communicating the pump cavity with the outside, so that the pump cavity is of a non-closed structure, the running resistance of the diaphragm can be reduced, and the diaphragm can run more smoothly. The specific reasons are as follows: when the medium is sucked, the external medium can firstly enter the pump cavity through the through groove 11, and the medium entering the pump cavity is used for assisting to push the diaphragm to move in a direction away from the pump cavity, namely the diaphragm is easier to move in a direction for increasing the volume of the pump cavity; when discharging the medium, the medium in the pump chamber can first be discharged out of the pump chamber through the through groove 11, making the diaphragm more easily movable in a direction to reduce the volume of the pump chamber. Therefore, the diaphragm pump is not only convenient to install and disassemble quickly, but also has the characteristics of low running resistance and energy consumption reduction.

Of course, the above is only a typical example of the utility model, and other embodiments of the utility model are also possible, and all technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of the utility model claimed.
