Detailed Description

For a better illustration of the utility model, reference is made to the following description, taken in conjunction with the accompanying drawings and examples:

the utility model discloses a rubber cylinder which comprises a cylinder body 1, wherein a rubber cavity 2 is arranged in the cylinder body 1, a piston 5 is connected in the rubber cavity 2 in a sliding mode, an oil storage tank 13 is arranged in the middle of the piston 5, a top cover 7 is connected to one end of the cylinder body 1 in a threaded mode, a gasket 9 is arranged between the top cover 7 and the cylinder body 1, and a rubber nozzle group is connected to one side, close to the top cover 7, of the gasket 9.

Further, it is organized including gluey mouth a set of and gluey mouth two, it is organized including running through and fixed connection in to glue a set of mouth the extrusion mouth 8 of gasket 9, detachable cover is equipped with first gluey mouth 3 on the extrusion mouth 8, it is organized including fixed connection in to glue mouth 6 of second of gasket 9.

Further, both ends of barrel 1 all are equipped with the external screw thread, and can both with top cap 7 threaded connection and installation glue mouth group.

Furthermore, the top cover 7 is provided with an annular array of grooves 11, the grooves 11 are matched with an additionally configured screwing wrench 12, and the screwing wrench 12 is used when the top cover 7 is not unscrewed by bare hands.

Further, a lubricating oil block is arranged in the oil storage tank 13 and used for reducing the resistance of the piston 5 during movement.

Further, the top cover 7 is provided with ribs (not shown) and grooves (not shown) which are uniformly distributed at equal intervals and used for increasing the screwing friction force.

Further, the barrel 1 is provided with an unscrewing indication direction of the top cover 7.

Specifically, when the glue gun needs to be used, the cylinder 1 is placed in the glue gun, after the glue gun is pressed down, the piston 5 moves to the left under the action of the glue gun, so that the piston 5 pushes the glue solution to the left side, the glue solution is sprayed out from the first glue nozzle 3 or the second glue nozzle 6 through the extrusion port 8, the gluing operation is completed, after the piston 5 moves to the left end, the direction of the cylinder 1 can be turned, then the glue solution starts to be filled by taking the left end as the start, and then the piston 5 is pushed to the left side from the right side again, so that the operation of returning the piston 5 is reduced;

because the piston 5 is internally provided with the lubricating oil block, the resistance between the piston 5 and the inner wall of the rubber cavity 2 is smaller, therefore, the action of pressing the glue gun can be smoother, the pressure required by the fingers of a person to press is small, the glue discharging of the first glue nozzle 3 or the second glue nozzle 6 can be stable and uniform, the situation that the manual pressing needs large force when the resistance of the piston 5 is large is avoided, thereby causing the resistance of the piston 5 to move forward for a large distance after the static friction force is suddenly changed into the sliding friction force, causing the situation of excessive glue application, meanwhile, the pressure in the glue cavity 2 is also larger, and the glue solution is extruded from the first glue nozzle 3 or the second glue nozzle 6 after the glue is applied, and the momentarily excessive glue pressure may cause the glue 2 to penetrate into the inside of the piston 5 or into the gap of the cap 7, therefore, the problem that the piston 5 is difficult to move or the top cover 7 is difficult to open after the glue solution is solidified is solved, and the problem can be solved well by lubricating the piston 5;

moreover, as the gasket 9 is arranged in the top cover 7, the gasket 9 is tightly attached to the left end of the barrel 1, so that the glue solution in the glue cavity 2 is not easy to seep out, the situation that the top cover 7 is fixedly stuck by the seeped glue solution is well lightened, and the top cover 7 can be forcibly opened by the screw cap wrench 12 even after being stuck, the cover opening time consumed when the top cover 7 is difficult to open due to the fixation of the glue solution is greatly reduced, and the actual gluing efficiency is improved;

moreover, the gasket 9 is arranged, so that the situation that the top cover 7 is not easy to open due to negative pressure adsorption or positive pressure pushing in the rubber cavity 2 can be well avoided.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the technical solutions of the present invention have been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that the technical solutions described in the foregoing embodiments can be modified or some technical features can be replaced equally; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
