Document Type and Number:
WIPO Patent Application WO/2022/156310
Kind Code:
A1
Abstract:
A pump body clamping device, comprising a clamping seat (2) fixed at one side of a box body (4), the clamping seat (2) being provided with a first channel (21) penetrating through both sides thereof, a first end of the first channel (21) being configured to allow for the insertion of a push rod (5), and a second end of the first channel (21) being configured to allow for the screwing of a pump body (1); and a pump body seat (3) provided inside the first channel (21) and being capable of rotating relative to the clamping seat (2), the pump body seat (3) being provided with a second channel (31) penetrating through both sides thereof and allowing for the insertion and clamping of the pump body (1). A detection element (22) is provided on the clamping seat (2); an induction body (32) is provided on the pump body seat (3); and when the pump body (1) is inserted into the second channel (31) and screwed along the first channel (21), the pump body seat (3) rotates in the first channel (21), such that the induction body (32) is located within a detection range of the detection element (22). By detecting the screwing degree of the pump body on the clamping seat, the occurrence of improper screwing of the pump body is avoided, thereby improving the use safety.
