Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 to 5, the utility model provides a quantitative filler, which comprises a filler pipe 1, a filler rod 2 and a rotating rod 3, wherein the filler rod 2 is movably arranged in the filler pipe 1, the filler rod 2 is of a hollow structure, and the rotating rod 3 is rotatably arranged in the filler rod 2; the bottom end of the filling rod 2 is fixedly connected with a fixed block 12, and the fixed block 12 is in threaded connection with the rotating rod 3; a limiting mechanism is arranged in the fixed block 12; the bottom end of the rotating rod 3 is fixedly connected with a piston 13, and the piston 13 is arranged below the fixed block 12

When the filling device absorbs liquid, the filling rod 2 is pulled to move upwards, and when the filling rod moves to a designated position, the limiting mechanism limits the liquid, so that the fixed block 12 and the filling rod 2 cannot move under the action of the limiting mechanism, at the moment, the rotating rod 3 in the filling rod 2 is rotated, so that the piston 13 moves downwards, and the liquid can be accurately and quantitatively discharged;

Further, a limit groove 11 which can be matched with the limit block 21 is formed in the inner wall of the filling pipe 1; a limiting rod 4 which can be matched with the limiting block 21 is arranged in the filling rod 2;

The limiting mechanism comprises a spring 22 and a limiting block 21, as shown in fig. 3 and 4, one end of the spring 22 is fixed on the filling rod 2, and the other end is fixedly connected with the limiting block 21; the limiting block 21 is provided with a groove 221 and an inclined plane connected with the groove 221, when the limiting block 21 is limited, one end of the limiting block 21 is positioned in the limiting groove 11, the groove 221 and the inclined plane are positioned outside the limiting groove 11, and the inclined plane is positioned at one end of the limiting block 21 close to the spring 22; when the limiting rod 4 moves downwards, the limiting rod can be abutted against the inclined surface of the limiting block 21, and downward force is applied, and the limiting block 21 can move towards the direction of the spring 22 under the pressure of the limiting rod 4, so that the limiting block 21 moves out of the limiting groove 11, and limiting is released;

further, the limiting grooves 11 are plural and longitudinally and equidistantly arranged along the inner wall of the filling pipe 1, as shown in fig. 2; when the required liquid output is large, the limiting can be carried out at a proper position according to the requirement, and then the rotating rod 3 is used for fine adjustment, so that the use efficiency can be improved;
