DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Such as Figures 1 - 3As shown in the figure, an embodiment of the present utility model provides a bottom shaft water stop device, which includes a mounting substrate 200 arranged on one side of the bottom shaft 100. The end of the mounting substrate 200 extends towards the bottom shaft 100. A water stop pad 212 is provided at the end of the mounting substrate 200. A water stop strip 211 is provided on one side of the water stop pad 212. The water stop strip 211 is in pressing contact with the surface of the bottom shaft 100. The water stop pad 212 and the water stop strip 211 are integrally formed. A locking component for locking the position of the water stop pad 212 is provided on the bottom shaft 100. The water stop pad 212 is fixed by the locking component, which facilitates the replacement of the water stop strip 211 and the water stop pad 212 in the later stage;

[0021] The locking component includes an L-shaped seat 209 that presses tightly against the upper end surface of the water stop pad 212. A limiting slot 214 matching the water stop pad 212 is provided at the lower end of the L-shaped seat 209. Anti-slip nails matching the surface of the water stop pad 212 are provided on the inner wall of the limiting slot 214. A guiding member is provided between the L-shaped seat 209 and the bottom shaft 100. Limiting side rods 213 for limiting the side surface of the L-shaped seat 209 are symmetrically provided at the upper end of the bottom shaft 100. The limiting side rods 213 are in pressing contact with the end of the water stop pad 212. A plurality of adjusting bolts 201 are rotatably provided on the bottom shaft 100 on one side of the L-shaped seat 209. A lower pressing plate 205 is threaded on the adjusting bolts 201. A lower pressing positioning slot 206 matching the lower pressing plate 205 is provided on the L-shaped seat 209. An adjusting knob 202 is provided at the upper end of the adjusting bolt 201. By driving the relative rotation of the adjusting bolt 201 and the lower pressing plate 205 through the adjusting knob 202, the lower pressing plate 205 generates a downward pressure on the L-shaped seat 209 to complete the locking of the position of the L-shaped seat 209;

[0022] An auxiliary pressing seat 208 is provided on the L-shaped seat 209. The auxiliary pressing seat 208 is connected to the L-shaped seat 209 through a connecting bolt 210. An auxiliary pressing strip 207 for pressing the surface of the water stop strip 211 is provided on the side of the auxiliary pressing seat 208. Under the action of the auxiliary pressing strip 207, a downward pressure can be obtained on the upper end surface of the water stop strip 211, which helps to provide a tight pressure for sealing;

[0023] A wear-resistant layer is provided on the pressing surface of the water stop strip 211, which helps to improve the service life of the equipment;

[0024] The guiding member includes a plurality of connecting plates 204 provided on the L-shaped seat 209. A guiding rod 203 is slidably provided at the end of the connecting plate 204. The lower end of the guiding rod 203 is connected to the upper end of the bottom shaft 100, so that the L-shaped seat 209 can slide up and down along the guiding rod 203.

[0025] Working principle: An installation substrate 200 is arranged on one side of the bottom shaft 100, and then a water stop strip 211 and a water stop pad 212 are arranged at the upper end of the installation substrate 200 through a locking component. The water stop strip 211 and the water stop pad 212 are integrally arranged, and a relatively large installation area is provided at the position of the water stop pad 212. Then, the water stop strip 211 is tightly pressed against the arc surface of the bottom shaft 100. With the cooperation of the auxiliary pressing strip 207, the water stop strip 211 will obtain a greater pressure, and a sealing line is formed between the water stop strip 211 and the outer side surface of the bottom shaft 100, ensuring that the gate is always in a sealed state during actual rotation.

[0026] 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.
