Aiming at the problems in the prior art, the embodiment of the utility model provides a quantitative discharging device.

Examples

As shown in FIGS. 1 to 3, a quantitative discharging device comprises a transparent material storage tube 1; the material storage pipe 1 is cylindrical; the outer side of the material storage pipe 1 is provided with a first scale 2; the storage pipe 1 comprises a front end opening and a rear end opening; a piston 3 in sliding connection is arranged in the storage pipe 1; the piston 3 is connected with a first piston shaft 4; a discharge pipe 5 is detachably arranged on the opening at the front end of the storage pipe 1; the upper end of the discharge pipe 5 is provided with a discharge hole 6; a sealing cover 7 is arranged on the discharge port 6; a sleeve 8 is detachably arranged on the opening at the rear end of the material storage pipe 1; a second piston shaft 9 is sleeved in the sleeve 8 in a sliding manner; the second piston shaft 9 is detachably connected to the first piston shaft 4. The discharging pipe 5 is in threaded connection or tightly sleeved connection with the material storage pipe 1; the material storage pipe 1 and the sleeve 8 are in threaded connection or tightly sleeved; one end of the second piston shaft 9, which is far away from the first piston shaft 4, is provided with a piston handle 10; a supporting table 11 is arranged on the outer ring of the material storage pipe 1; a retainer ring 12 fixed with the second piston shaft 9 is arranged on one side of the sleeve 8 close to the piston 3; the retainer ring 12 can prevent the second piston shaft 9 from separating from the sleeve 8; preventing loss.

The discharge pipe 5 is transparent; a second scale 13 corresponding to the first scale 2 is arranged on the outer side of the discharge pipe 5; the first scale 2 and the second scale 13 are continuous; the sealing cover 7 is screwed or clamped on the discharge hole 6; the sealing cover 7 is provided with a connecting soft strip 14 connected with the discharge pipe 5; the connecting soft strip 14 is used for preventing the sealing cover 7 from being lost; the outer rings of the material storage pipe 1, the material discharge pipe 5 and the sleeve 8 are provided with anti-slip grains (not shown in the figure), and the anti-slip grains are arranged to increase friction force, so that the installation of a user is facilitated. The first piston shaft 4 is positioned in the material storage pipe 1 and can avoid factors such as collision in transportation and the like from causing damage to the first piston shaft or leakage of a product; but also can reduce the volume and facilitate the package.

One end of the first piston shaft 4, which is far away from the piston 3, is provided with a cylindrical clamping groove 15; a baffle 16 is arranged in the clamping groove 15; a clamping block 17 is clamped between the baffle 16 and the bottom of the clamping groove 15; the clamping block 17 is fixedly connected with a connecting shaft 18; the connecting shaft 18 is fixed at one end of the second piston shaft 9 close to the first piston shaft 4; the cylindrical clamping groove 15, the connecting shaft 18, the first piston shaft 4 and the second piston shaft 9 are concentrically arranged.

The baffle 16 of the present embodiment is two symmetrically arranged sector plates; a slot is formed between the two sector plates; the section shape of the combination of the connecting shaft 18 and the clamping block 17 is consistent with the shape of the slot; after the connecting shaft 18 and the latch 17 are inserted into the slots, the latch 17 can be latched between the baffle 16 and the bottom of the latch slot 15 by rotating the connecting shaft 18. To remind the user that the rotation is in place, a limit plate (not shown) may be provided between the baffle 16 and the bottom of the slot 15. The advantage of this design is that the second piston shaft 9 can be separated from the first piston shaft 4 by rotating the second piston shaft 9; the second piston shaft 9 and the sleeve 8 are taken down by disassembling the sleeve 8 and the material storage pipe 1, so that the length of the whole device is reduced, and the device is easier to package; and because the remaining first piston shaft 4 is shorter, the material can be placed in the material storage pipe 1, and damage or product leakage caused by transportation collision and the like is avoided.

The quantitative discharging device of the utility model uses the structure of an injector for reference; the main difference lies in that the discharging pipe 5 is detachable and can be supplemented with products; the first piston shaft 4 and the second piston shaft 9 can be detached, the length of the whole device can be reduced, two operations of pushing and pulling can be realized by the connection mode of the first piston shaft 4 and the second piston shaft 9, and the device can be quickly reset after a product is used up.
