Description

Technical Field

[0001] The utility model relates to the technical field of airtightness detection of a housing, in particular to an airtightness detection device for a housing. Background Art

[0002] Products produced in many industries need to be subjected to airtightness detection. Some products have high requirements for airtightness. When the airtightness fails to meet the requirements, the products will fail. One common method for detecting airtightness is to add liquid to the product and observe whether there is liquid leakage. This requires injecting water into the product, but some products are not suitable for injecting water inside. Another method is to inject gas into the product and place it in water to see if there is air leakage. This method is widely used.

[0003] The utility model with the publication number of CN207408053U discloses an airtightness detection device for a housing, which includes a water tank. A double-axis lifting cylinder is arranged in the water tank. A magnetic induction switch is installed on the side of the double-axis lifting cylinder. The upper end of the double-axis lifting cylinder is connected with a bracket. A pressure regulating valve is arranged at the upper end of the bracket. A pressing cylinder is arranged on one side of the pressure regulating valve. A pressing end cover is arranged at the front end of the pressing cylinder.

[0004] When in use, this device can only detect the airtightness of a single product. After the detection is completed, the product needs to be disassembled and taken out, and then a new product needs to be placed, resulting in low work efficiency and slow detection speed. Therefore, we propose an airtightness detection device for a housing. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an airtightness detection device for a housing, so as to solve the existing problems to a certain extent.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] An airtightness detection device for a housing includes a fixed frame. A hydraulic rod is fixedly installed at the top of the fixed frame. A fixed sleeve is fixedly installed on the inner wall of the bottom of the fixed frame. A water tank is fixedly installed at the rear of the inner wall of the bottom of the fixed frame. A motor is fixedly installed inside the fixed sleeve. The output end of the motor is fixedly installed with a fixed frame; a rotating assembly, the rotating assembly is installed on the fixed frame; a reset assembly, the reset assembly is installed on the fixed frame.

[0008] As a further improvement of the above solution, the rotating assembly includes a fixed plate, a support plate, a sliding rod and a limiting plate. The fixed plate is fixedly installed around the outside of the fixed frame. The support plate is fixedly installed on the outside of the fixed frame. One side of the support plate is fixedly installed on the upper and lower sides of the fixed plate. The sliding rod is slidably installed inside the fixed plate and arranged in sequence from left to right. The limiting plate is fixedly installed on the top of the sliding rod.

[0009] As a further improvement of the above solution, the reset assembly includes a spring, a limiting block, a connecting shell, an air pump and a connecting pipe. The spring is fixedly installed on the top of the fixed plate. The limiting block is fixedly installed on the outside of the sliding rod. The connecting shell is fixedly installed at the bottom of the sliding rod. One end of the spring is fixedly installed on the bottom of the limiting plate. The air pump is fixedly installed on the top of the connecting shell. One end of the connecting pipe is fixedly installed on one side of the air pump. The other end of the connecting pipe is fixedly installed on the top of the connecting shell.

[0010] As a further improvement of the above solution, an installation groove is opened at the top of the fixed sleeve, and the motor is fixedly installed inside the installation groove.

[0011] As a further improvement of the above solution, a plurality of sliding grooves are opened at the top of the fixed plate. The sliding rod is slidably installed inside the sliding grooves. The outer diameters of the limiting plate and the limiting block are larger than the inner diameter of the sliding grooves.

[0012] By adopting the above technical solution, the sliding grooves facilitate the sliding of the sliding rod, and the limiting plate and the limiting block limit the sliding distance of the sliding rod.

[0013] As a further improvement of the above solution, a fixing groove is opened at the top of the connecting shell, and the connecting pipe is fixedly installed inside the fixing groove.

[0014] By adopting the above technical solution, the fixing groove facilitates the installation of the connecting pipe, enabling the device to detect the air tightness of the product.

[0015] As a further improvement of the above solution, the fixed plate and the support plate are made of steel, and the support plate is triangularly arranged.

[0016] By adopting the above technical solution, the fixed plate and the support plate have a good supporting effect, making the device not easily damaged during use.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] (1) A shell airtightness detection device of the present utility model can connect a product to a connection shell through a set rotation assembly. After the detection of the product on one side is completed, the motor can be controlled to drive the drive shaft to rotate, so that the drive shaft can drive the fixing frame, the fixing plate and the support plate to rotate, thereby rotating the fixed product, enabling the hydraulic rod to press the next product to be detected into the inner side of the water tank. And the staff can disassemble the detected product on one side and install the product to be detected, improving the work efficiency.

[0019] (2) A shell airtightness detection device of the present utility model can drive the limit plate and the sliding rod to slide down through a set reset assembly after the hydraulic rod presses down, enabling the limit plate to limit the sliding rod, so that the sliding rod can drive the connection shell and the product into the inner side of the water tank. The air pump and the connecting pipe are convenient for detecting airtightness. And after the hydraulic rod cancels the downward pressure, the spring can drive the sliding rod to return to its position, and the limit block is convenient for preventing the sliding rod from easily detaching, restricting the sliding distance of the sliding rod.
