Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm pumps, in particular to a clamp-type diaphragm pump. Background Art

[0002] The diaphragm pump is a commonly used industrial pump that uses a diaphragm to achieve the suction and discharge of liquids. This pump usually consists of two diaphragms and a liquid chamber in the middle. The diaphragm is vibrated by compressed air or hydraulic pressure to achieve the suction and discharge of liquids.

[0003] The diaphragm pump of the prior art has the following disadvantages during use:

[0004] On the one hand, the air inlet pipe is plugged into the pneumatic control valve of the diaphragm pump for use, but there is a lack of anti-detachment structure between the air inlet pipe and the pneumatic control valve, which makes it easy to fall off due to external accidental contact, thus greatly affecting the stability of the diaphragm pump;

[0005] Secondly, the bottom of the diaphragm pump is supported only by a base. However, when moving the diaphragm pump, it needs to be moved manually, which is time-consuming and labor-intensive. There is a lack of structure on the base that can assist manual pushing and moving. For this reason, we designed a clamp-type diaphragm pump to solve the above problems. Summary of the invention

[0011] Preferably, a transmission column fixedly connected between two guide seats is provided obliquely above the moving block, an L-shaped guide plate is movably sleeved on the outer side of the transmission column, and a transmission channel cooperating with the transmission column is opened on the L-shaped guide plate.

[0012] Preferably, the bottom end of the L-shaped guide plate is fixedly connected to a slider with a convex structure in vertical cross-section, and the two sliders are slidably connected to the slide groove provided at the top of the base. The two sliders are threadedly connected with hand screws, and the bottom ends of the hand screws after being tightened are pressed against the inner bottom wall of the slide groove.

[0013] Preferably, the clamping and anti-slip structure includes a ring fixed at the top air inlet of the pneumatic control valve, a plug-in ring is inserted in a slot provided on the ring, the plug-in ring is fixed to the outside of the air pipe, an L-shaped block is fixed to the outside of the ring, a T-shaped column is movably inserted on the L-shaped block, and a socket matching the T-shaped column is opened on the outside of the plug-in ring.

[0014] Preferably, a side wall of the L-shaped block facing away from the insertion hole is fixedly connected to the T-shaped column via a spring, and the spring is sleeved on the outer side of the T-shaped column.

[0015] Compared with the prior art, the utility model has the following beneficial effects: in the utility model, by setting a retractable movable structure, Figure 1 As shown in , two rollers are arranged at the bottom ends of the two moving blocks on the base, which can facilitate manual pushing of the diaphragm pump body for moving and transporting, and are easy to use. When the two rollers at the bottom ends of the two moving blocks need to be stored, the corresponding hand screws can be loosened, and the two L-shaped guide plates on the base can be moved relative to each other, and the driving block can be driven to move up tiltedly with the action of the transmission channel and the transmission column, so that the rollers are away from the top of the external support body, so that the rollers can be stored easily to avoid the rollers from contacting the ground for a long time and affecting their stability.

[0016] By setting up a clamping and anti-detachment structure, the T-shaped column, under the action of the spring, can clamp and fix the plug hole on the plug ring, thereby effectively preventing one end of the air pipe from detaching from the pneumatic control valve, avoiding affecting the stability of the diaphragm pump body.
