Detailed Description

As shown in fig. 1 and 2, a quantitative rubber dropping tube for pathological sealing sheets, comprising a dropper tube 1, wherein the dropper tube 1 contains resin adhesive for sealing sheets, the dropper tube 1 is made of transparent material and is marked with scales on the surface thereof, a dropper 2 is installed at the front end of the dropper tube 1, a push rod 3 which can move along the length direction of the dropper tube 1 is arranged in the dropper tube 1, a piston 4 is arranged at the inner end of the push rod 3 and is used for pushing out the resin adhesive in the dropper tube 1, the outer end of the push rod 3 extends out from the rear end of the dropper tube 1, a push rod pushing mechanism 5 is arranged at the rear end of the dropper tube 1, and the push rod 3 can be pushed by the push rod pushing mechanism 5 to move towards the inner direction of the dropper tube 1 according to a fixed.

Specifically, the push rod pushing mechanism 5 includes a sleeve 501 disposed at the tail end of the dropper tube 1, a pushing tube 502 capable of moving along the length direction of the sleeve 501 is disposed in the sleeve 501, the push rod 3 passes through the pushing tube 502, a spring 507 is disposed outside the pushing tube 502, the top end of the spring 507 is fixed to the outer wall of the pushing tube 502, the bottom end of the spring 507 is fixed to the inner wall of the sleeve 501, a flower-shaped chuck 503 for clamping the push rod 3 is disposed at one end of the pushing tube 502 close to the dropper tube 1, specifically, the flower-shaped chuck 503 is tubular, one end of the flower-shaped chuck is an elastic split structure, specifically, the flower-shaped chuck is divided into two or three segments, the two or three segments are identical to the flower-shaped chuck of the mechanical pencil (as shown in fig. 3), a locking hoop 504 capable of moving along the length direction of the flower-shaped chuck 503 under the external force is sleeved at the flower-shaped chuck 503, the, when the inner wall of the sleeve 501 is provided with a first limiting ring 505 and a second limiting ring 506, the locking hoop 504 is positioned between the first limiting ring 505 and the second limiting ring 506, when the propelling pipe 502 moves forwards, the first limiting ring 505 can enable the locking hoop 504 to move backwards relative to the blooming chuck 503 to release the constraint of the blooming chuck 503 on the push rod 3, the second limiting ring 506 can push the locking hoop 504 to move forwards relative to the blooming chuck 503, when the propelling pipe 502 moves backwards and returns to the original position, the constraint of the locking hoop 504 on the blooming chuck 503 is restored, and the structure and the working principle of the push rod propelling mechanism 5 are consistent with those of a common propelling pencil.

For convenient operation, the tail end of the pushing tube 502 is fixed with a pressing block 6, and the outer end of the push rod 3 is provided with a gripper 7.

The utility model discloses the theory of operation who makes as follows:

when resin glue needs to be sucked, an operator holds the dropper tube body 1 by hand and presses the pressing block 6 with fingers and keeps a pressing state, so that the pushing tube 502 moves forwards, the first limiting ring 505 pushes the locking hoop 504 on the blooming chuck 503 in the process, the locking hoop 504 moves backwards relative to the blooming chuck 503, and the constraint of the blooming chuck 503 on the push rod 3 is relieved; at the moment, the push rod 3 can move freely, then the dropper 2 extends into the resin glue container, and the hand grip 7 is held by hand to pull the push rod 3 backwards, so that the branches can be sucked into the dropper tube body 1.

When the glue dripping sealing piece is needed, the pressing block 6 is pressed once by fingers, in the downward pressing process, the pushing pipe 502 moves forwards, in the moving process, the pushing pipe 502 drives the push rod 3 to move forwards, the piston 4 at the inner end of the push rod 3 pushes the resin glue in the dropper pipe body 1 out from the dropper 2 for sealing piece, when the locking hoop 504 touches the first limiting ring 505, the restraint of the blooming chuck 503 on the push rod 3 is released, the push rod 3 stops moving forwards, at the moment, the lowest end is pressed, and at the moment, the spring 507 is stretched; then the pressing block 6 is released, the push tube 502 moves backwards and returns to the original position under the action of the pulling force of the spring 507, in the process, the restraint of the push rod 3 by the flowering chuck 503 is released, so the push rod 3 can not return to the original position along with the push tube 502, when the push tube 502 returns to the original position, the second limiting ring 506 touches the locking hoop 504, the locking hoop 504 moves forwards relative to the push tube 502, the flowering chuck 503 is restrained again, so that the flowering chuck 503 clamps the push rod 3 again, and a complete pressing operation is completed, and the process is the same as the principle of automatic lead.

The advancing distance of the push rod 3 is equal to the distance between the initial positions of the first limit ring 505 and the locking hoop 504, and the advancing displacement of the push rod 3 is the same when the push rod is pressed each time, namely, the amount of resin glue pushed out each time is the same, so that quantitative glue dripping is realized.
