DETAILED DESCRIPTION

[0024] The utility model is now described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0025] Please refer to Figure 1-8 , an elastic sealing structure of a quantitative powder box, comprising a powder tube 1 and a shell 2 below the powder tube 1, the powder tube 1 is provided with a powder injection port 4 at the top, and a powder outlet 5 at the bottom of the shell 2, a plurality of slots 3 are provided around the shell 2, one of the slots 3 is provided with a plug plate 6 for isolating powder, an inner shell 21 is provided inside the shell 2, a positioning plate 22, an elastic plate 23 and an extension plate 25 are provided on the outer wall of the inner shell 21, the elastic plate 23 is provided between the positioning plate 22 and the extension plate 25, the plug plate 6 is provided between the elastic plate 23 and the extension plate 25, and under normal conditions, the bottom surface of the elastic plate 23 always elastically contacts the surface of the extension plate 25, and the inner right-angled edge of the elastic plate 23 always contacts the outer wall of the inner shell 21.

[0026] In this embodiment, the plug plate 6 includes a plug plate handle and a gate plate 61. The plug plate handle is arranged outside the outer shell 2, and the gate plate 61 extends into the inner shell 21. When the gate plate 61 is inserted into the insertion gap 3, the surface of the gate plate 61 contacts the bottom surface of the elastic plate 23, and the bottom surface of the gate plate 61 contacts the surface of the extension plate 25, thereby realizing the sealing of the inside and outside of the powder cartridge.

[0027] On the outside of the inner shell, the positioning plate 22, the elastic plate 23, the gate plate 61 and the extension plate 25 are arranged in sequence from top to bottom; due to the elastic contact between the elastic plate 23 and the positioning plate 22, when the gate plate 61 is not inserted into the insertion slot 3, the bottom surface of the elastic plate 23 is always on the surface of the extension plate 25, and the internal powder cannot leak out from the insertion slot; when the gate plate 61 fits the extension plate 25 and is inserted into the insertion slot 3, the gate plate 61 elastically lifts the elastic plate 23, and after being lifted up, the bottom surface of the elastic plate 23 is pressed on the surface of the gate plate 61, and the bottom surface of the gate plate 61 is in contact with the extension plate 25, so the insertion of the gate plate 61 will also prevent the internal powder from leaking out from the insertion slot; the inside and outside of the powder box are sealed to avoid powder leakage.

[0028] In the utility model, the positioning plate 22 is fixed to the inner shell 21 by screws 225, positioning through holes 221 are provided on both sides of the positioning plate 22, a positioning countersunk hole 222 is provided between the two positioning through holes 221, and a connecting hole 223 is provided on the outer side of the positioning plate 22. The screws 225 fix the positioning plate 22 to the inner shell 21 at the connecting hole 223.

[0029] In addition, the elastic plate 23 includes two positioning columns 231 and two elastic columns 232 on the surface. The two elastic columns 232 are each provided with a second spring 233. The positioning columns 231 correspond to the positioning through holes 221, and the elastic columns 232 and the second spring 233 correspond to the positioning countersunk holes 222.

[0030] Since the elastic plate 23 is arranged below the positioning plate 22, the positioning column 231 and the positioning through hole 221 and the elastic column 232 and the positioning countersunk hole 222 are plugged in and out of each other; wherein, the positioning column 231 is never separated from the positioning through hole 221, and since a second spring 233 is also provided on the top of the elastic column 232; therefore, when the elastic plate 23 moves upward, the second spring 233 will be compressed in the positioning countersunk hole.

[0031] The second spring 233 is always in a compressed state.

[0032] Please refer again Figure 4-5, it can be seen that the positioning plate 22 and the elastic plate 23 are positioned and plugged in and connected by the positioning column 231 and the elastic column 232. The establishment of the positioning column 231 and the elastic column 232 can limit the movement of the elastic plate 23, and the elastic plate 23 can only move vertically up and down; at the same time, the second spring 233 makes the vertical edge of the elastic plate always fit the outer wall of the inner shell through the positioning plate, and maintains the displacement of the elastic plate in the vertical direction, thereby ensuring the vertical sealing effect between the elastic plate and the outer wall of the inner shell; that is to say, the elastic plate always moves vertically and fits the outer wall of the inner shell, plays an elastic floating role, which can further improve the sealing effect of the powder box and make it automatically sealed.

[0033] The specific usage is as follows: when the gate plate 61 fits the extension plate 25 and is inserted into the insertion gap 3, the gate plate 61 lifts up the elastic plate 23 as a whole. After being lifted up, the second spring 233 is further compressed. Through the elastic force of the second spring 233, the bottom surface of the elastic plate 23 can be tightly pressed against the gate plate 61, thereby achieving a sealing effect, and the internal powder cannot leak out from the insertion gap.

[0034] Since the second spring 233 is always in a compressed state, when the gate plate 61 is pulled out from the insertion slot 3, the elastic force of the second spring 233 can push the elastic plate 23 downward. After the gate plate 61 is pulled out, the bottom surface of the elastic plate 23 contacts the surface of the extension plate 25, which also plays a sealing role.

[0035] When in use, powder is poured into the powder tube, and the gate plate 61 is inserted to separate the internal powder into upper and lower parts. At this time, the powder below the gate plate 61 can be discharged through the powder outlet 5 .

[0036] In this embodiment, different slots 3 correspond to different volumes of powder, and different volumes of powder can be obtained by inserting the gate plate 61 into different slots 3; when in use, the gate plate 61 can be inserted according to the amount of powder to be taken, so that the powder can be taken out quantitatively to ensure the powder taking accuracy.

[0037] Based on the above embodiment, each of the slots 3 corresponds to an extension plate 25, an elastic plate 23, a positioning plate 22 and an extension plate 25; whether the gate plate 61 is inserted into the slot 3 or not, the sealing can be ensured to prevent the powder in the cylinder from leaking out.

[0038] As a preferred solution, a nut 24 is provided on the surface of the inner shell 21, and the screw 225 is connected to the nut 24 in the connecting hole 223. A step 224 and a first spring 226 are also provided in the connecting hole 223. One end of the first spring 226 is in contact with the step 224, and the other end is squeezed by the screw 225, so that the overall elasticity is squeezed, the connection strength is increased, and the overall structure is more stable.

[0039] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
