Detailed Description

The embodiments of the invention will be described in detail below with reference to the accompanying fig. 1 to 2, but the invention can be implemented in many different ways as defined and covered by the claims.

With reference to fig. 1 to 2, the dosing funnel is provided with a horizontal tube 1, a vertical tube 6 and a funnel body 7, the utility model provides a well site dosing funnel elastic positioning device, which fixes a positioning ring I12 and a positioning ring II10 on the horizontal tube 1, the positioning ring II10 is located behind the positioning ring I12, and the positioning ring II10 is transversely provided with a guide through hole 11; a sliding block 8 is movably sleeved on the horizontal pipe 1 between the positioning ring I12 and the positioning ring II10, the sliding block 8 can slide along the horizontal pipe 1, a clamping jaw 2 made of an elastic metal sheet is fixedly arranged on the side surface of the sliding block 8, and the clamping jaw 2 penetrates through the guide through hole 11; a compression spring 4 is movably sleeved on the horizontal pipe 1 between the positioning ring I12 and the sliding block 8, one end of the compression spring 4 acts on the rear face of the positioning ring I12, and the other end of the compression spring 4 acts on the front face of the sliding block 8.

According to the structure of the above embodiment, it can be found that, since the sliding block 8 can slide on the horizontal pipe 1 between the positioning rings I12 and II10, the claws 2 fixedly connected with the sliding block 8 can be extended or pulled back, since the claws 2 are elastic metal sheets and are matched with the guide through holes 11, the claws 2 can be unfolded when being extended, the tail ends of the claws can be attached to the inner wall of the outlet of the casing, and the sliding block 8 is acted by the compression spring 4, since the positioning rings I12 are fixed, the elastic force of the compression spring 4 can act on the front of the sliding block 8, so that the claws 2 are extended and unfolded.

With reference to fig. 1 to 2, the sliding block 8 is a square block, and the clamping jaws 2 are fixedly arranged on four side surfaces of the sliding block 8; correspondingly, the guide through holes 11 are four guide through holes 11 uniformly opened along the circumferential direction of the positioning ring II 10.
