Description

Technical Field

[0001] The utility model belongs to the technical field of detection equipment, and particularly relates to an airtightness detection device. Background Art

[0002] A toilet, also called a sitting toilet, is a common sanitary appliance in our daily life and can meet people's defecation needs. Before packaging, the toilet needs to be subjected to airtightness detection to ensure the product quality of the toilet. When the existing detection equipment is used, the water inlet, the sitting toilet opening and the sewage outlet need to be blocked simultaneously, and then the inside of the toilet is pressurized. After standing for a period of time, the air pressure inside the toilet is detected to obtain the airtightness detection result of the toilet.

[0003] However, only the blocking components for the sitting toilet opening and the sewage outlet are equipped on the existing detection equipment, and the blocking of the water inlet needs to be carried out manually. Usually, a rubber block is stuffed into the water inlet for blocking, and the rubber block is stuck in the water inlet by friction, and the stability is poor. When the inside of the toilet is pressurized, the air pressure will push the rubber block, resulting in the loosening or even popping out of the rubber block, affecting the detection result. Content of the Utility Model

[0004] In order to solve the problems in the above background art, the utility model provides an airtightness detection device. The lifting component drives the lifting plate to move downward, and the lifting plate drives the water inlet blocking piece to move and block the water inlet. With the pressing of the lifting plate, the water inlet blocking piece has higher stability, thereby reducing the detection error.

[0005] The utility model provides an airtightness detection device for detecting the airtightness of a toilet. The toilet is provided with a sitting toilet opening, a water inlet and a sewage outlet, and comprises a detection table. A sewage outlet blocking pad is arranged on the detection table, and the toilet is placed on the sewage outlet blocking pad. An water inlet blocking mechanism for blocking the water inlet is arranged on the detection table. The water inlet blocking mechanism comprises a vertically lifting lifting plate. A lifting component for driving the lifting plate to move is arranged on the detection table. An water inlet blocking piece is arranged on the lifting plate. When the lifting plate moves downward, the water inlet blocking piece blocks the water inlet. A sitting toilet opening blocking mechanism for blocking the sitting toilet opening and an air pressure detection component for detecting the airtightness of the toilet are also arranged on the detection table.

[0006] Further, a guide rod is vertically arranged on the detection table, the lifting plate is vertically slidably connected to the guide rod. The lifting component comprises a first threaded rod vertically arranged and rotatably connected to the detection table. The first threaded rod penetrates through the lifting plate and is threadedly connected to the lifting plate. A driven bevel gear is fixed on the first threaded rod. A fixed frame is arranged on the detection table. A rotating shaft is horizontally rotatably connected to the fixed frame. A first hand wheel is fixed to one end of the rotating shaft, and a driving bevel gear is fixed to the other end of the rotating shaft. The driving bevel gear is meshed with the driven bevel gear.

[0007] Further, the water inlet blocking piece is a hemispherical rubber block.

A chute is horizontally formed in the lifting plate. The sliding plate is movably arranged in the chute. The water inlet plugging member is arranged on the sliding plate. A second threaded rod is horizontally rotatably connected in the lifting plate. The second threaded rod penetrates through the sliding plate and is in threaded connection with the sliding plate. A second hand wheel is arranged at one end of the second threaded rod.

[0009] Furthermore, a steering assembly is provided between the water inlet plugging member and the sliding plate. The steering assembly includes a vertically arranged fixing rod. The fixing rod is fixed on the sliding plate. The bottom end of the fixing rod is rotatably connected with a steering frame. The water inlet plugging member is fixed on the steering frame. A steering fixing block is fixed on the side wall of the fixing rod. Plug holes are formed in both the fixing rod and the steering fixing block. An inserting rod is arranged in the steering frame. When the steering frame is vertically arranged, the inserting rod is inserted into the plug hole of the fixing rod. When the steering frame is horizontally arranged, the inserting rod is inserted into the plug hole of the steering fixing block.

[0010] Furthermore, a split pin for preventing the inserting rod from coming out is arranged in the inserting rod.

[0011] Furthermore, the toilet seat plugging mechanism includes a fixing plate located above the toilet. A support rod is arranged between the detection table and the fixing plate. At least one air cylinder is vertically arranged on the bottom surface of the fixing plate. A pressing plate is arranged at the bottom end of the air cylinder. A toilet seat plugging pad for plugging the toilet seat is arranged on the bottom surface of the pressing plate.

[0012] Furthermore, the air pressure detection component includes an air inlet pipe and an air pressure sensor.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] (1) When it is necessary to plug the water inlet, the lifting assembly can drive the lifting plate to move downward. The lifting plate drives the water inlet plugging member to move downward. Thus, the water inlet plugging member plugs the water inlet. Due to the pressing of the lifting plate, the water inlet plugging member can stably block the water inlet, improving the stability of the water inlet plugging member and thereby reducing the detection error.

[0015] (2) When detecting toilets of different sizes, the distance between the toilet seat and the water inlet will change. The sliding assembly can drive the water inlet plugging member to move horizontally, thereby adjusting the horizontal position of the water inlet plugging member so that the water inlet plugging member can plug the water inlet.

[0016] (3) When detecting a toilet with the water inlet on the side wall, the direction of the bogie can be adjusted through the steering assembly so that the bogie and the water inlet plug are arranged horizontally. Then, the lifting assembly drives the lifting plate to move downward so that the water inlet plug is on the same horizontal plane as the water inlet. Subsequently, the sliding assembly drives the water inlet plug to move horizontally, and the water inlet plug seals the water inlet. BRIEF DESCRIPTION OF THE DRAWINGS
