However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides a silicone sealant extrusion storage structure, comprising: an outer cylinder 1, a handle 4 is fixedly connected to the outer surface of the outer cylinder 1 near the middle position, a front cover 2 is arranged on the front end surface of the outer cylinder 1, a rear cover 3 is arranged on the rear end surface of the outer cylinder 1, an adjustment component 5 is arranged on the rear end surface of the rear cover 3, and a pushing component 6 is arranged on the inner surface of the outer cylinder 1; an adjustment component 5, the adjustment component 5 comprises a connecting cylinder 501, the connecting cylinder 501 is fixedly connected to the rear end surface of the rear cover 3, a connecting tube 503 is arranged on the front end surface of the connecting cylinder 501, the outer surface of the connecting tube 503 is fixedly penetrated through the rear end surface of the rear cover 3, the rear end surface of the connecting cylinder 501 is fixedly connected with a first sealing plate 502, the rear end surface of the first sealing plate 502 is symmetrically provided with electric telescopic rods 506, the telescopic ends of the two electric telescopic rods 506 are both slidably penetrated through the rear end surface of the first sealing plate 502, the telescopic ends of the two electric telescopic rods 506 are both fixedly connected with adjustment blocks 505, the outer surface of the adjustment blocks 505 slides A stopper 504 is connected, and the outer surface of the stopper 504 is fixedly connected to the inner surface of the connecting tube 501. A plurality of air outlet holes 509 are evenly provided on the outer surface of the adjusting block 505 near the front end surface of the stopper 504. The stopper 504 and the adjusting block 505 are matched with each other. A bellows 507 is arranged at the center of the rear end surface of the adjusting block 505, and an air pipe 508 is arranged at the rear end surface of the bellows 507. The outer surface of the air pipe 508 is arranged on the outer surface of the handle 4 away from the bellows 507. The bellows 507 is connected to the adjusting block 505, and the air pipe 508 is connected to the bellows 507. The bellows 507 is connected to the handle 4. The inner surface of the front cover 2 is threadedly connected to the outer surface of the outer cylinder 1 near the front end surface, and the inner surface of the rear cover 3 is threadedly connected to the outer surface of the outer cylinder 1 near the rear end surface. The outer surface of the adjusting block 505 is slidably connected to the inner surface of the connecting tube 501, and the inside of the adjusting block 505 is hollow.

[0025] The effect achieved by the entire embodiment 1 is that when the silicone sealant is pushed by gas, the handle 4 is held, and the air inlet pipe arranged at the bottom of the handle 4 is connected to the air outlet end of the external stable air pressure controller. A switch is arranged on the outer surface of one side of the handle 4, so that the high-pressure gas flows into the handle and is transported to the connecting tube 501 through the air pipe 508 in turn, and is transported to the hollow regulating block 505 through the bellows 507. A plurality of air outlet holes 509 are evenly arranged on the outer surface of the regulating block 505 near the front end, and when it is connected to the connecting tube 501, the gas is allowed to enter through the air pipe 508.

The two electric telescopic rods 506 are started synchronously. The two telescopic ends will slide forward in the first sealing plate 502 and drive the adjustment block 505 to move in the connecting cylinder 501.

The multiple gas outlet holes 509 evenly arranged on the surface will gradually be exposed with the forward movement and communicate with the internal space of the connecting cylinder 501. When the gas outlet holes 509 contact the rear end surface of the stopper 504, the multiple gas outlet holes 509 will be completely exposed, the high-pressure gas flow will be accelerated, and the gas thrust will be increased. On the contrary, when the telescopic ends of the two electric telescopic rods 506 are reset and retracted, the adjusting block 505 will be pulled to make it fit closely with the connecting tube 501 and move backward. The bellows 507 will also shrink. At this time, the multiple gas outlet holes 509 will gradually fit with the inner side of the stopper 504, and the thrust of the high-pressure gas on the silicone sealant will decrease. Through the corresponding extension and contraction of the two electric telescopic rods 506, the adjusting block 505 will be driven The plurality of air outlet holes 509 evenly opened on the surface of the stopper 504 move forward and backward inside the stopper 504, so that the amount of gas entering is reduced after gradually overlapping with the stopper 504, thereby reducing the extrusion thrust of the silicone sealant. When the plurality of air outlet holes 509 are gradually exposed from the stopper 504, the thrust of the gas is increased, thereby solving the problem in the background technology that when the silicone sealant is extruded from the storage structure by pneumatic extrusion through the stable air pressure controller with power provided by the stable air pressure controller, it is inconvenient for personnel to adjust the air pressure when the working area is far away from the stable air pressure controller.

[0026] Embodiment 2, as Figure 1-Figure 5As shown, the pushing assembly 6 includes an inner cylinder 601, the rear end face of the inner cylinder 601 is arranged at the front end of the connecting pipe 503, the inner cylinder 601 and the connecting pipe 503 are connected, the outer surface of the inner cylinder 601 is fixedly connected to the inner surface of the outer cylinder 1, the inner surface of the inner cylinder 601 is matched with a piston 603, the front end face of the piston 603 is equidistantly arranged with a plurality of guide rods 604, the front end faces of the plurality of guide rods 604 are all fixedly connected with a push plate 8, the front end face of the inner cylinder 601 is fixedly connected with a second baffle 602, the outer surfaces of the plurality of guide rods 604 all slide through the rear end face of the second baffle 602, the inner surface of the outer cylinder 1 is matched with a hose 7 near the front end face of the inner cylinder 601, the outer surface of the hose 7 penetrates the inner surface of the front cover 2, the inner surface of the hose 7 is matched with a push plate 8 near the rear end face, and the push plate 8 is matched with the push block 605.

[0027] The effect achieved by the entire embodiment 2 is that when the silicone sealant is squeezed out from the storage structure, the front cover 2 is first twisted to open it, the hose 7 containing the silicone sealant is unpacked and its bottom is inserted from the front end of the outer cylinder 1, and the front cover 2 is covered on the outer cylinder 1. The cone-shaped tip outlet end of the front side of the hose 7 will be exposed from the front cover 2, and the front end of the hose 7 is limited by the front cover 2. The switch on the surface of the handle 4 is opened, so that the high-pressure gas connected below it enters the gas delivery pipe 508. This part is an existing mature technology, and its principle has been fully disclosed. Open, no further details are given here, the high-pressure gas passes through the regulated regulating block 505, enters the inner cylinder 601 from the connecting pipe 503, and under the action of the gas pressure, the push piston 603 is pushed to slide along the inner surface of the inner cylinder 601, driving the multiple guide rods 604 to slide in the second baffle 602, and the second baffle 602 plays a limiting role. The multiple guide rods 604 drive the push block 605 to squeeze the movable push plate 8 at the rear end of the hose 7, so that the glue inside the hose 7 containing silicone sealant can be evenly squeezed out.

[0028] Working principle: When in use, first twist the front cover 2, unpack the hose 7 containing silicone sealant and insert its bottom from the front end of the outer cylinder 1, cover the outer cylinder 1 with the front cover 2, and the cone-shaped tip outlet end of the front side of the hose 7 will be exposed from the front cover 2. The front end of the hose 7 is limited by the front cover 2, and the rear end of the hose 7 fits with the push block 605. The edge of the front end surface of the push block 605 is inclined, which can better guide the insertion into the hose 7. Push the push plate 8 to open the switch on the surface of the handle 4, so that the high-pressure gas connected below it enters the gas pipe 508. This part is an existing mature technology. The principle is fully disclosed and will not be described here. The two electric telescopic rods 506 are started synchronously, and the two telescopic ends will slide forward in the first sealing plate 502, and drive the adjusting block 505 to move in the connecting tube 501. The front end thereof will gradually slide forward from the inner side of the stopper 504, and the multiple air outlet holes 509 evenly arranged on the surface thereof will gradually be exposed with the forward movement and communicate with the internal space of the connecting tube 501. When the adjusting block 505 hits the rear end surface of the stopper 504, the multiple air outlet holes 509 will be completely exposed, and the flow of high-pressure gas will be accelerated, which plays a role in increasing the gas thrust. On the contrary, the two electric telescopic rods 506 When the telescopic end is reset and retracted, the adjusting block 505 will be pulled to make it fit closely with the connecting tube 501 and move backward, and the bellows 507 will also shrink. At this time, the multiple air outlet holes 509 will gradually fit with the inner side of the block 504, and the thrust of the high-pressure gas on the silicone sealant will decrease. Through the corresponding extension and contraction of the two electric telescopic rods 506, the adjusting block 505 is driven to move back and forth inside the block 504, so that the multiple air outlet holes 509 evenly opened on the surface gradually overlap with the block 504, reducing the amount of gas entering, thereby reducing the extrusion thrust of the silicone sealant, and the multiple air outlet holes 509 gradually move away from the block When exposed inside 504, the thrust of the gas is increased, and the high-pressure gas passes through the adjusted regulating block 505 and enters the inner cylinder 601 from the connecting pipe 503. Under the action of the gas pressure, the push piston 603 is pushed to slide along the inner surface of the inner cylinder 601, driving the multiple guide rods 604 to slide in the second baffle 602. The second baffle 602 plays a limiting role. The multiple guide rods 604 drive the push block 605 to squeeze the movable push plate 8 at the rear end of the hose 7, so that the glue inside the hose 7 containing silicone sealant can be evenly squeezed out, thereby improving the use effect of the silicone sealant extrusion and storage structure.
