[0016] Compared with the prior art, the present invention has the following beneficial effects:

The knob is turned to make the rubber water-stop sleeve fit the inner wall of the construction joint, and the rubber water-stop sleeve and the water-stop lip on the surface thereof can fit closely to the inner wall of the construction joint, thereby achieving an efficient anti-seepage sealing effect, ensuring that the water-stop structure and the construction joint achieve the best fitting state, avoiding the problem of poor water-stop effect caused by differences in construction joint specifications, and at the same time, the operation is simple, does not require complex tools or professional skills, and construction personnel can easily master it, which is convenient for rapid adjustment at the construction site, and can be fine-tuned at any time by turning the knob until the best water-stop effect is achieved;
[0018] The present invention improves the anti-seepage effect of the construction joint by arranging structures such as a water-stop lip and a water-swelling water-stop strip. After entering the construction joint, the infiltrated water will be first blocked by the rubber water-stop sleeve, and the infiltrated water on the side of the rubber water-stop sleeve will be blocked by the water-stop lip. When the infiltrated water breaks through the water-stop lip at a large angle or pressure, it will encounter the water-swelling water-stop strip, causing the swelling material inside the water-stop strip to absorb moisture and expand, thereby enhancing the water-stopping effect. The push plate is squeezed through the rubber water-stop sleeve, so that the space in the first cavity is further compressed through the first piston rod, so that the rubber water-stop sleeve is further filled, and the squeezing force between the push plate and the inner wall of the construction joint is increased, thereby improving the water-stopping effect of the rubber water-stop sleeve and the water-stop lip.

At the same time, the adaptive waterproof mechanism can effectively cope with the penetration conditions of different water pressures and water volumes, thereby improving the anti-seepage performance of the device and reducing maintenance costs.
[0019] The present invention improves the stability of the device by arranging a rubber water-stop sleeve and a spring. When the wall undergoes a slight displacement or deformation, the device can adapt to the deformation through the elasticity of the rubber water-stop sleeve and the spring, so that the rubber water-stop sleeve always contacts the inner wall of the construction joint, maintains the sealing and filling effect, and avoids the situation where the water-stop effect of the device is reduced due to wall deformation.

[0032] The knob 101 is rotationally connected to the side of the mounting base 301 away from the ventilation groove 303, the turntable 102 is rotationally connected to the rotating groove 308, and a plurality of protrusions 103 are fixedly connected to the inner wall of the rotating groove 308.

[0033] The above scheme is adopted: by setting the knob 101 and the push plate 110, it is convenient to carry out anti-seepage work on construction joints 403 of different specifications. The knob 101 is turned to rotate the turntable 102 and the gear 104. The rotation of the gear 104 will drive the rack 105 to slide inside the slide groove 302, drive the two sliders 106 to move away from each other, and drive the push plate 110 to squeeze the rubber water stop sleeve 201. At the same time, the push plate 110 will be subjected to pressure to move the first piston rod 108 in the direction close to the spring 109, squeeze the spring 109 and compress the space inside the first cavity 107, so that the gas in the first cavity 107 is discharged to the inside of the rubber water stop sleeve 201 through the vent hole 111 and the vent groove 303, increase the air pressure inside the rubber water stop sleeve 201 to make the rubber water stop sleeve 201 gradually expand, and when the push plate 110 pushes the rubber water stop sleeve 201, the water-expandable water stop strip 2 on its surface will expand when it encounters water. When the rubber water stop sleeve 201 is against the inner wall of the construction joint 403, the surface of the rubber water stop sleeve 201 will fit with the inner wall of the construction joint 403 under the action of its internal air pressure. At this time, the water stop lip 202 is against the inner wall of the construction joint 403, and then the knob 101 is stopped. It can be adjusted according to the construction joints 403 of different specifications, so that the rubber water stop sleeve 201 and the water-swellable water stop strip 203 and the water stop lip 202 on its surface can fit closely to the inner wall of the construction joint 403, thereby achieving an efficient anti-penetration sealing effect, ensuring the best fit between the water stop structure and the construction joint 403, avoiding the problem of poor water stop effect caused by differences in construction joint specifications, and simple operation, no need for complex tools or professional skills, easy to master by construction personnel, convenient for rapid adjustment at the construction site, and can be fine-tuned at any time by turning the knob 101 until the best water stop effect is achieved;
[0034] The protrusion 103 arranged inside the rotating groove 308 is engaged with the protrusion 103 on the turntable 102, and can resist the tendency of the turntable 102 to rotate in the opposite direction through mutual friction, thereby preventing the knob 101 from automatically rotating in the opposite direction, causing the rubber water-stop sleeve 201 to be released from the inner wall of the construction joint 403, and reducing the anti-seepage effect of the device.
[0035] like Figures 1 to 3As shown, the water-stop mechanism 2 includes a rubber water-stop sleeve 201, a water-swellable water-stop strip 203 is clamped on the side of the rubber water-stop sleeve 201, a water-stop lip 202 is fixedly connected to the side of the rubber water-stop sleeve 201, the rubber water-stop sleeve 201 is made of elastic material, the rubber water-stop sleeve 201 is sleeved on the side of the mounting seat 301 and fixedly connected thereto, the rubber water-stop sleeve 201 is located on the side of the resistance plate 307 away from the knob 101, the water-stop lip 202 is located on the side of the water-swellable water-stop strip 203 away from the resistance plate 307, the thickness of the rubber water-stop sleeve 201 is the same as the thickness of the resistance plate 307, the sides of the two push plates 110 away from each other are both against the inner wall of the rubber water-stop sleeve 201, the water-swellable water-stop strip 203 is located on the side of the push plate 110 close to the rubber water-stop sleeve 201, and the vent 111 is connected to the interior of the rubber water-stop sleeve 201 through the vent groove 303.
[0036] The main body structure 4 includes a wall 401, an installation groove 402 is provided on the wall 401, a construction joint 403 is provided inside the installation groove 402, the size of the construction joint 403 is larger than the size of the installation groove 402, a slope is provided on the side of the contact plate 307 close to the wall 401, and the side of the rubber water stop sleeve 201 away from the contact plate 307 passes through the installation groove 402 and extends to the inside of the construction joint 403.
[0037] The above scheme is adopted: by setting up the waterproof lip 202 and the water-swelling waterstop strip 203 and other structures, the anti-seepage effect of the construction joint 403 is improved. After the infiltrated water enters the construction joint 403, it will be blocked by the rubber waterproof sleeve 201 first, and the infiltrated water on the side of the rubber waterproof sleeve 201 will be blocked by the waterproof lip 202. When the infiltrated water breaks through the waterproof lip 202 at a large angle or pressure, it will encounter the water-swelling waterstop strip 203, causing the expansion material inside to absorb moisture and expand, thereby enhancing the waterproof effect, and squeezing the push plate 110 through the rubber waterproof sleeve 201, so that The space in the first cavity 107 is further compressed by the first piston rod 108, so that the rubber water stop sleeve 201 is further filled, so that the extrusion force between the rubber water stop sleeve 201 and the inner wall of the construction joint 403 is increased, and the water stop effect of the rubber water stop sleeve 201 and the water stop lip 202 is improved. Through the synergistic effect of the rubber water stop sleeve 201, the water stop lip 202 and the water-swelling water stop strip 203, multiple lines of defense are constructed to prevent leakage of the construction joint 403. At the same time, the adaptive waterproof mechanism can effectively cope with the penetration of different water pressures and water volumes, thereby improving the anti-penetration performance of the device and reducing the maintenance cost;
[0038] By providing the rubber water-stop sleeve 201 and the spring 109, the stability of the device is improved. When the wall undergoes a slight displacement or deformation, the device can adapt to the deformation through the elasticity of the rubber water-stop sleeve 201 and the spring 109, so that the rubber water-stop sleeve 201 always contacts the inner wall of the construction joint 403, maintains the sealing and filling effect, and avoids the situation where the water-stop effect of the device is reduced due to wall deformation.
[0039] The working principle and use process of the present invention are as follows: first, align the mounting seat 301 with the mounting groove 402 reserved on the wall 401 and move the end close to the rubber waterproof sleeve 201 toward the inside of the construction joint 403. During the movement, when the rubber waterproof sleeve 201 passes through the mounting groove 402, the inclined surface of the abutment plate 307 will abut against the inner wall of the mounting groove 402, and the abutment plate 307 will move toward the mounting seat 301 by squeezing the inclined surface, squeezing the gas in the second cavity 304 and the second spring 306. When the rubber waterproof sleeve 201 is completely moved, After moving into the construction joint 403, the abutment plate 307 completely moves into the installation groove 402. At this time, the two sides of the abutment plate 307 respectively abut against the mounting seat 301, and the air pressure in the second cavity 304 and the elastic force of the second spring 306 abut against the inner wall of the mounting groove 402, so that the mounting seat 301 is fixed inside the mounting groove 402. In this process, the rubber water stop sleeve 201 abuts against the inner wall of the construction joint 403 and squeezes the gas inside the rubber water stop sleeve 201, so that the side of the rubber water stop sleeve 201 gradually fits with the inner wall of the construction joint 403.
[0040] Then, the knob 101 is turned to rotate the turntable 102 and the gear 104. The rotation of the gear 104 will drive the rack 105 to slide inside the slide groove 302, drive the two sliders 106 to move away from each other, and drive the push plate 110 to squeeze the rubber waterproof sleeve 201. At the same time, the push plate 110 will be pressurized to make the first piston rod 108 move in the direction close to the spring 109, squeeze the spring 109 and compress the space inside the first cavity 107, so that the gas in the first cavity 107 is discharged to the inside of the rubber waterproof sleeve 201 through the vent hole 111 and the vent groove 303, increase the air pressure inside the rubber waterproof sleeve 201 to make the rubber waterproof sleeve 201 gradually expand. 10 When the rubber water-stop sleeve 201 is pushed so that the water-swellable water-stop strip 203 on its surface abuts against the inner wall of the construction joint 403, the surface of the rubber water-stop sleeve 201 will fit against the inner wall of the construction joint 403 under the action of the internal air pressure. At this time, the water-stop lip 202 abuts against the inner wall of the construction joint 403. Then stop turning the knob 101, and set a protrusion 103 inside the rotating groove 308 to engage with the protrusion 103 on the turntable 102. The tendency of the turntable 102 to rotate in the opposite direction can be resisted by mutual friction. Finally, a layer of waterproof membrane reinforcement layer is fixed on the side of the mounting seat 301 close to the knob 101 to seal the gap between the mounting seat 301 and the mounting groove 402.
