[0002] The pressure-resistant sanitary tower is a container for storing liquids, which has the characteristics of high pressure resistance, cleanliness and hygiene, and is widely used in daily life and production. The pressure-resistant sanitary tower usually consists of a pressure-resistant tower body, a tower door, tower plates, etc. The tower body is generally made of high-quality stainless steel and other materials, which has good pressure resistance and corrosion resistance, and can withstand a certain internal pressure without deformation or damage. The tower door is designed tightly to ensure that there is no leakage during operation and to ensure the hygienic safety of the operating environment.

[0003] However, the existing pressure-resistant sanitary towers still have the following problems when in use: the connection between the tower door and the tower body of the traditional pressure-resistant sanitary tower is not firm. After long-term use, gaps will occur between the tower door and the tower body, resulting in the flow of gas, liquid, and dust substances into the tower body, causing pollution.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Refer to the instruction manual Figure 1-9The utility model provides a pressure-resistant tower door, comprising a back plate 1 on a pressure-resistant tower, a cover plate 2 being provided at the front end of the back plate 1, the thickness of the cover plate 2 being twice that of the back plate 1, and the cover plate 2 being integrally formed, so that the cover plate 2 can withstand greater pressure, and when the cover plate 2 is subjected to external pressure impact, the pressure can be dispersed to the entire cover plate 2, thereby avoiding deformation or damage of the cover plate 2 caused by excessive local force;

[0030] The cover plate 2 and the back plate 1 are connected by two connecting assemblies 3 distributed vertically. Specifically, each set of connecting assemblies 3 includes a connecting rod 301, and connecting pins 302 are fixed at both ends of the connecting rod 301. Each connecting pin 302 is sleeved with a base 303. The connecting pin 302 is connected to the base 303 through a cotter pin 304. The base 303 at one end of the connecting rod 301 is fixed to the back plate 1, and the base 303 at the other end of the connecting rod 301 is fixed to the cover plate 2;

[0031] The cover plate 2 is provided with two pressure rod assemblies 4 distributed up and down, each pressure rod assembly 4 includes a pressure plate 401, the pressure plate 401 is detachably fixed to the cover plate 2 by a plurality of bolts 405, and openings 402 are provided on both sides of the front end of the pressure plate 401. The front end of the back plate 1 is fixed with a plurality of hinges 404, and each hinge 404 is movably provided with a bolt 405. The bolt 405 is connected to the hinge 404 through a spring pin 406. Two locking washers 407 are provided between the spring pin 406 and the hinge 404. One end of the bolt 405 is threadedly connected to a handle 5 for fixing the pressure plate 401;

[0032] A frame-shaped gasket 6 is provided between the cover plate 2 and the back plate 1. A frame-shaped embedding groove 7 is provided at the rear end of the cover plate 2. The frame-shaped gasket 6 is inserted into the frame-shaped embedding groove 7. The frame-shaped gasket 6 can improve the sealing between the cover plate 2 and the back plate 1. Handles 10 are fixed on both sides of the front end of the cover plate 2. The two handles 10 are provided between the two connecting rods 301 to facilitate the staff to open the cover plate 2.

[0033] When in use, the staff first flips the cover plate 2 onto the back plate 1, and then toggles the two handles 5 in turn, buckles the handle 5 and the bolt 405 into the opening 402, and then tightens the handle 5 to press against the pressure plate 401. With the help of the pressure plate 401, the cover plate 2 is firmly covered on the back plate 1, so that the cover plate 2 and the back plate 1 are tightly fitted to ensure the sealing and safety of the door. At the same time, a frame-shaped gasket 6 is set between the cover plate 2 and the back plate 1. The frame-shaped gasket 6 is squeezed when the cover plate 2 is closed, filling the gap between the cover plate 2 and the back plate 1, thereby preventing substances such as gas, liquid or dust from entering through the gap, further improving the sealing performance of the cover plate 2. When the cover plate 2 needs to be opened, the handle 5 on the bolt 405 is first loosened, and then the handle 5 is turned to move out of the opening 402 to open the cover plate 2. The structure is simple and the operation is very convenient.

[0034] Moreover, there are no any other welded parts on the inner wall of the cover plate 2, and the inner wall of the cover plate 2 is polished to a roughness below 0.6um to ensure that dust will not adhere to the inner wall of the cover plate 2.

By using the cooperation of the limiting blocks 9 and the limiting grooves 8, the firmness between the U-shaped wear-resistant piece 403 and the opening 402 can be improved;

[0036] Moreover, the two U-shaped wear-resistant pieces 403 are both fixed to the pressing plate 401 by two screws, which is convenient for installing and disassembling the U-shaped wear-resistant piece 403.

[0037] By arranging the U-shaped wear-resistant piece 403 inside the opening 402, it is used to protect the inner wall of the opening 402, avoid the damage of the opening 402 caused by the friction between the bolt 405 and the inner wall of the opening 402. After long-term use, the staff only needs to loosen the screws to take out the U-shaped wear-resistant piece 403 from the opening 402 for replacement, and at the same time, the pressing plate 401 can also be disassembled for inspection and replacement.

[0038] Finally: The above are only the preferred embodiments of the present invention, and are not used to limit the present invention.
