Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to a product air tightness inspection tool. Background Art

[0002] Anode Bar is an English term that mainly refers to the rod-shaped object used in the anode part of the electrolysis process. During the electrolysis process, the anode bar is usually made of conductive materials such as copper or aluminum. They are designed to withstand the heat and chemical reactions generated during the electrolysis process. A key function of the anode bar is to serve as a path for electron outflow during the electrolysis process, thereby allowing metal ions to be extracted from the solution.

[0003] In the prior art, when cleaning Anode bar products, air leakage often occurs when the product is used by customers after cleaning, necessitating an airtightness test on the product. This airtightness test generally uses manual visual inspection to check the integrity and flatness of the product's sealing port. However, due to the long-term cleaning of customer products, the sealing end surface may be damaged or have minor scratches, and the visual inspection method cannot guarantee that the product is completely sealed. Utility Model Content

[0004] The purpose of the present invention is to provide a product airtightness inspection tool to solve the problems raised in the above background technology.

[0006] A sealing plate is fixedly connected to the upper surface of the first threaded sleeve, and a limiting sleeve is fixedly connected to the upper surface of the second threaded sleeve. A workpiece is sleeved between the sealing plate and the limiting sleeve, and a sealing cover is sleeved at one end of the workpiece. A connecting pipe is fixedly connected to one side of the sealing cover, a pressure gauge is provided on one side of the connecting pipe, and an electromagnetic ball valve is installed on one side of the pressure gauge.

[0007] Preferably, the lower surface of the support plate is fixedly connected to the bottom plate, and a group of two support plates are provided and are symmetrically arranged about the center plane of the bottom plate, and a limit frame is fixedly connected between the two support plates.

[0008] Preferably, sliding columns are fixedly connected to both sides of the first threaded sleeve and the second threaded sleeve, and the sliding column sleeve is arranged in the limit frame and is slidably connected to the limit frame.

[0009] Preferably, a sealing sheet is fixedly connected to one side of the sealing plate, an inner sealing ring is fixedly connected to one side of the sealing sheet, and an outer sealing ring is provided on one side of the inner sealing ring.

[0010] Preferably, the outer sealing ring is fixedly connected to the inner ring surface of the sealing plate, the inner ring surface of the sealing cover is fixedly provided with a sealing sleeve, and the sealing cover, the limiting sleeve and one end of the workpiece are fixedly connected by a stud bolt and a nut.

[0011] Preferably, one end of the connecting pipe is fixedly connected to one end of the tee, the other end of the tee is fixedly connected to the electromagnetic ball valve, and the pressure gauge is fixedly connected to the top end of the tee.

[0012] Compared with the prior art, the beneficial effect of the present invention is that the first threaded sleeve and the second threaded sleeve are driven to move toward each other through the rotation of the threaded rod, thereby causing the sealing plate and the limit sleeve to move toward each other, and the end of the workpiece is sealed with the cooperation of the sealing cover, the inner sealing ring, the outer sealing ring and the sealing sleeve, and then connected to one end of the electromagnetic ball valve through an external pressurizing device, so that the interior of the workpiece is aerated, and the internal pressure of the workpiece rises.

[0025] While limiting one end of the workpiece 8 by the limiting sleeve 7, the other end of the workpiece 8 is inserted into the sealing plate 6 and abuts against the sealing sheet 16, and at the same time, the inner sealing ring 17 is sleeved on the inner ring surface of the other end of the workpiece 8, and the outer sealing ring 18 is sleeved on the outer ring surface of the other end of the workpiece 8, so that the other end of the workpiece 8 is sealed by the sealing sheet 16, the inner sealing ring 17, and the outer sealing ring 18, so as to ensure airtightness. The workpiece 8 is provided with a sealing sleeve 19 in one end of the limiting sleeve 7, and the sealing sleeve 19 is fixedly sleeved on the inner ring surface of the sealing cover 9, so that the stud bolts connect the limiting sleeve 7, the sealing cover 9, and the workpiece 8. One end of the workpiece 8 is fixedly connected, thereby ensuring the sealing of the end of the workpiece 8. Under the connection of the connecting pipe 10, the tee 20 and the electromagnetic ball valve 12, the external pressurizing equipment is connected to one end of the electromagnetic ball valve 12, so that the inside of the workpiece 8 is aerated and the internal pressure of the workpiece 8 rises.
