Description

Technical Field

[0001] The utility model relates to the technical field of air bag pumps, in particular to an anti-corrosion air bag pump. Background Art

[0002] A bellows pump is a device that produces fluid flow by changing the pressure around a flexible bag. It usually consists of a flexible bag and an external pressure source, such as a pneumatic piston, pneumatic motor, or other compressed air device. When pressure is applied by the external pressure source, the bellows contracts, driving the liquid or gas to flow through the pipe system. When the pressure source is released, the bellows expands and sucks in new liquid or gas. When cleaning the outside of the bellows pump, improper operation or failure to properly close the relevant valves will cause corrosive liquids to drip onto the outer casing of the bellows pump. Although the bellows pump is made of corrosion-resistant materials, if the liquid dripping on the outer casing of the bellows pump is not cleaned up in time, the bellows pump will still corrode due to long-term contact with corrosive liquids.

[0003] Therefore, the utility model designs a corrosion-resistant air bag pump. Utility Model Content

[0030] Furthermore, the sleeve mechanism includes a first baffle cover 2 and a second baffle cover 3 arranged outside the air bag pump body 1, the bottom end of the air bag pump body 1 is fixedly connected to a base 11, and a plurality of pairs of telescopic rods 12 are fixedly connected to the base 11. The interiors of the first baffle cover 2 and the second baffle cover 3 are fixedly connected to a support sleeve rod 231 for supporting the sliding of the telescopic rod 12, and the ends of the telescopic rod 12 away from the base 11 are fixedly connected to a telescopic spring 232 for pushing the first baffle cover 2 and the second baffle cover 3 to automatically open outward with the air bag pump body 1 as the center. The function of the telescopic spring 232 is to enable the first baffle cover 2 and the second baffle cover 3 to automatically open outward with the air bag pump body 1 as the center by starting the switch mechanism.

[0031] The switch mechanism includes mounting slots 233 provided at the top of the first and second shields 2 and 3, wherein a button 31 is slidably connected in one of the mounting slots 233, a connecting rod 35 is fixedly connected inside the second shield 3, a supporting plate 36 is fixedly connected to the end of the connecting rod 35 away from the second shield 3, a reset spring 37 fixedly connected to the button 31 is fixedly connected to the supporting plate 36, and the reset spring 37 is used to automatically restore the button 31 to its original position for operation when there is no pressure from the hand. A pair of telescopic blocks 33 for clamping the first shield 2 are provided on the button 31.

[0032] Furthermore, the switch mechanism further comprises an arc-shaped clamping block 21 fixedly connected to the first blocking cover 2, a pair of clamping grooves 22 for clamping the telescopic block 33 are provided on the arc-shaped clamping block 21, a pair of telescopic grooves 32 for the telescopic block 33 to slide are provided on the button 31, and a clamping strip is provided inside the telescopic groove 32 for clamping the telescopic block 33 and sliding closely against the telescopic groove 32, and the function of the clamping strip is to limit the telescopic block 33 to slide only inside the telescopic groove 32. A push spring 34 is provided inside the telescopic groove 32 for pushing the telescopic block 33 to slide outward along the telescopic groove 32, and the function of the push spring 34 is that when the telescopic block 33 is not subjected to a restraining force, it will automatically pop outward and clamp into the clamping groove 22 or wait to be clamped into the clamping groove 22.

When the first block cover 2 and the second block cover 3 need to be closed to protect the air bag pump body 1, it is only necessary to push the first block cover 2 and the second block cover 3 in the direction of the air bag pump body 1, and reverse the above operation through the switch mechanism. Without further explanation, the first block cover 2 and the second block cover 3 can be quickly closed, which is simple and easy to operate.
