In this way, it is impossible to accurately control the glue injection volume during glue injection, and it is very easy to have too much or too little glue, which seriously affects the normal progress of the thermal insulation work and reduces the work efficiency. In view of this, the utility model proposes a glue injection device for interior and exterior wall thermal insulation projects. Content of the Utility Model

In this cycle, through the reciprocating movement of the piston, the amount of glue exported each time is the same, avoiding the problem of reduced insulation work efficiency caused by too much or too little glue volume.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0023] As Figures 1 to 5 shown, this embodiment proposes a glue injection device for interior and exterior wall insulation projects, including a cylinder body 1. One end of the cylinder body 1 is fixedly connected to a glue injection pipe 2, and the top of the cylinder body 1 is fixedly connected to a feed pipe 3. The inlet end of the feed pipe 3 is provided with a glue storage component 4 for introducing glue into the feed pipe 3. A glue outlet check valve 6 is fixedly connected to the glue injection pipe 2, and a glue inlet check valve 7 is fixedly connected to the feed pipe 3. The fluid direction inside the glue outlet check valve 6 is from the outlet end of the cylinder body 1 to the outlet end of the feed pipe 3, and the fluid flow direction inside the glue inlet check valve 7 is from the inlet end of the feed pipe 3 to the inlet end of the cylinder body 1. A piston assembly 5 is arranged inside the cylinder body 1. The piston assembly 5 includes a piston 51, and the piston 51 is slidably connected to the inside of the cylinder body 1. One side of the piston 51 is fixedly connected to a push rod 52. The push rod 52 penetrates through the side wall of the cylinder body 1 and is slidably connected to the side wall of the cylinder body 1. The end of the push rod 52 away from the piston 51 is fixedly connected to a connecting plate 53. The bottom end of the connecting plate 53 is provided with an operating member 54 for driving the connecting plate 53 to move horizontally through manual operation. A spring 55 is sleeved on the push rod 52. One end of the spring 55 abuts against the connecting plate 53, and the other end of the spring 55 abuts against the outer wall of the cylinder body 1.

[0024] By operating the operating member 54 to make the connecting plate 53 move horizontally, at this time the spring 55 is compressed and stores elastic potential energy, which makes the push rod 52 drive the piston 51 to slide away from the glue injection pipe 2, thus reducing the internal pressure of the cylinder body 1. In this way, the feed pipe 3 introduces the glue inside the glue storage component 4 into the cylinder body 1. Then, stop operating the operating member 54. At this time, the spring 55 releases its potential energy, making the piston 51 slide in the reverse direction and approach the glue injection pipe 2, thereby increasing the internal pressure of the cylinder body 1. This makes the glue injection pipe 2 export the glue inside the cylinder body 1 to inject glue into the wall. In this cycle, by the reciprocating movement of the piston 51, the amount of glue exported each time is the same, avoiding the problem of reducing the insulation work efficiency due to too much or too little glue volume.

[0025] Further, the glue storage assembly 4 includes a glue storage tank 41. A glue guiding pipe 42 is fixedly connected to the outlet end of the glue storage tank 41. The outlet end of the glue guiding pipe 42 is threadedly connected to the feed pipe 3 and is internally connected to the feed pipe 3. A control valve 43 is fixedly connected to the glue guiding pipe 42. By threadedly mating the glue guiding pipe 42 with the feed pipe 3, the quick installation of the glue storage tank 41 can be achieved. By opening the control valve 43, the pipeline between the glue guiding pipe 42 and the feed pipe 3 can be opened to facilitate the introduction of the glue in the glue storage tank 41 into the interior of the feed pipe 3.

[0026] Further, a transparent observation window 8 is fixedly connected to the outer side of the cylinder body 1, and a scale disk 9 is fixedly connected to the outer side of the observation window 8. The transparent observation window 8 can facilitate the operator to penetrate the liquid level position of the glue inside the cylinder body 1, and the amount of glue inside the cylinder body 1 can be observed through the scale disk 9.

[0027] Further, the operating member 54 includes a sliding rod 541 which is slidably connected to the bottom end of the cylinder body 1. One end of the sliding rod 541 is fixedly connected to the connecting plate 53. A hand-held rod 542 is fixedly connected to the bottom of the cylinder body 1. The inner side of the hand-held rod 542 is rotatably connected to a rotating rod 543 through a pin shaft. One end of the rotating rod 543 is hinged to a connecting rod 544. The end of the connecting rod 544 away from the rotating rod 543 is hinged to the other end of the sliding rod 541. The sliding rod 541 is arranged parallel to the push-pull rod 52, and the length of the sliding rod 541 is greater than the distance between the connecting plate 53 and the outer wall of the cylinder body 1. By applying pressure to the bottom end of the rotating rod 543, the rotating rod 543 rotates, which causes the top end of the rotating rod 543 to apply a pulling force to the connecting rod 544, and thus the connecting rod 544 pulls the sliding rod 541 to slide, so that the connecting plate 53 approaches the cylinder body 1. At this time, the spring 55 is compressed to store elastic potential energy, which causes the push-pull rod 52 to drive the piston 51 to slide away from the injection pipe 2, so that the internal pressure of the cylinder body 1 decreases. In this way, the feed pipe 3 introduces the glue inside the glue storage assembly 4 into the interior of the cylinder body 1. Then, the operation of the operating member 54 is stopped. At this time, the spring 55 releases its potential energy, causing the piston 51 to slide in the reverse direction and approach the injection pipe 2, so that the internal pressure of the cylinder body 1 increases, and thus the injection pipe 2 discharges the glue inside the cylinder body 1 to inject glue into the wall.

[0028] Further, a limiting member 56 for restricting the moving position of the connecting plate 53 is provided at the top of the cylinder body 1. The limiting member 56 includes an ear seat 561, and the ear seat 561 is fixedly connected to the top of the cylinder body 1. A screw rod 562 penetrating through the ear seat 561 is threadedly connected to the top end of the ear seat 561. One end of the screw rod 562 is fixedly connected with a stop block 563, and the connecting plate 53 can be in contact with the stop block 563 by translation. The other end of the screw rod 562 is fixedly connected with a rotating cap 564. The screw rod 562 is arranged parallel to the push-pull rod 52, and the length of the screw rod 562 is greater than the distance between the connecting plate 53 and the outer wall of the cylinder body 1. By rotating the rotating cap 564, the screw rod 562 rotates, which causes a relative displacement between the screw rod 562 and the ear seat 561, and thus the stop block 563 moves horizontally. In this way, the distance between the stop block 563 and the connecting plate 53 can be adjusted, so that the displacement of the connecting plate 53 can be adjusted, and then the displacement of the piston 51 can be adjusted. Furthermore, the amount of glue discharged by the cylinder body 1 each time can be adjusted, and the amount of glue injection into different walls can be adjusted, greatly improving the versatility of the device.

[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
