Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pressure resistance testing technology, specifically relating to a pressure burst test fixture for thin plates. Background Technology
[0002] Some conduits and cables in electronic equipment require isolation and protection during installation, typically using thin plastic sheets with internal perforations and compartments. The pressure resistance of these plastic sheet protective sleeves needs to be tested and verified to ensure their effectiveness in protecting the conduits and cables.
[0003] However, due to the thin, light, and easily bent nature of the plastic sheet protective sleeve under clamping force, it is difficult to fix it during testing and even more difficult to ensure its internal airtightness. Therefore, the results of pressure resistance tests are usually not accurate enough. Currently, there is an urgent need to design a special fixture to perform pressure resistance tests to ensure the accuracy of the test results. Utility Model Content
[0004] In view of the above-mentioned problems in the prior art, the purpose of this utility model is to provide a thin plate pressure burst test fixture, which ensures the airtightness of the workpiece under test by means of an adjustable first plug and a second plug, so as to improve the accuracy of the test results; and protects the workpiece under test by means of a screw and a protective sleeve, thereby improving the safety of the test process.
[0005] A pressure burst resistance test fixture for thin plates includes a protective sleeve for mounting the workpiece to be tested. The workpiece to be tested is hollow inside. The protective sleeve is disposed between two screws. A first plug and a second plug are respectively installed on the screws and connected to both ends of the workpiece to be tested. The first plug and the second plug are used to ensure the airtightness of the workpiece to be tested. A pressure head is installed on the second plug, through which liquid or gas is injected into the workpiece to be tested.
[0006] Preferably, the first plug and the second plug move on the screw and are fixed in position by the limiting member.
[0007] Preferably, the limiting component is a locking nut.
[0008] Preferably, the length of the protective sleeve is less than the length of the workpiece to be tested.
[0009] Preferably, both the first plug and the second plug include a cover plate and a mounting block, wherein the cover plate and the mounting block are snapped together, and a sealing gasket is provided between the cover plate and the mounting block.
[0010] Preferably, a pressure head is installed on the mounting block of the second plug, and a cavity is opened at the position of the pressure head on the mounting block of the second plug, through which the workpiece to be tested and the pressure head are connected.
[0011] Preferably, the sealing gasket in the second plug has a through hole that matches the inner hole of the workpiece to be tested, so that gas or liquid in the cavity can enter the workpiece to be tested.
[0012] The beneficial effects of this utility model are: the thin plate pressure resistance and burst test fixture, by sleeved with a protective sleeve, can prevent the slender and thin workpiece from bending to a large extent, and at the same time can protect the workpiece during the pressure resistance test, preventing it from flying fragments when it bursts, thus improving the safety of the test process.
[0013] By connecting the first and second plugs, which are adjustable in position on the screw, to both ends of the workpiece to be tested, the airtightness of the workpiece is ensured, which helps to improve the accuracy of the test results. Attached Figure Description

[0020] Example 1
[0021] like Figures 1 to 3 As shown, a pressure burst test fixture for thin plates includes a protective sleeve 1, screws 2, a first plug 3, a second plug 6, and a pressure head 7. The protective sleeve 1 is positioned between the two screws 2 to cover the workpiece 100 under test, preventing it from bursting and generating flying fragments during the pressure burst test.
[0022] The workpiece 100 to be tested is a thin plate with a hollow interior. Both ends of the workpiece 100 to be tested are connected to the first plug 3 and the second plug 6, respectively. The first plug 3 and the second plug 6 are used to ensure the airtightness of the workpiece 100 to be tested. The second plug 6 is equipped with a pressure head 7, which is used to connect to external equipment. Liquid or air pressure is injected into the interior of the workpiece 100 to be tested through the pressure head 7, and the workpiece 100 to be tested is subjected to pressure burst test using hydraulic and air pressure.
[0023] like Figure 1 , Figure 2 As shown, the first plug 3 and the second plug 6 are mounted on the screw 2 and their positions can be adjusted to accommodate workpieces 100 of different lengths. Furthermore, a limiting member 5 is mounted on the screw 2, and the positions of the first plug 3 and the second plug 6 are fixed by adjusting the position of the limiting member 5. In this embodiment, the limiting member 5 is a locking nut, which, through the threaded engagement between the locking nut and the screw 2, fixes and clamps the first plug 3 and the second plug 6 under force. The first plug 3 and the second plug 6 are made of stainless steel to ensure strength and durability.
[0024] It should be noted that the length of the protective sleeve 1 is less than the length of the workpiece 100 to be tested. The shorter protective sleeve 1 allows for the deformation of the workpiece 100, facilitating better connection of both ends of the workpiece 100 with the first plug 3 and the second plug 6. In this embodiment, the workpiece 100 to be tested is a thin plastic sheet with six internal compartments, its internal holes being square holes with a diameter of 4*4mm, a cross-sectional height of 5mm, a width of 30mm, and a length of 1000mm. Therefore, the length of the protective sleeve 1 is set to 980mm.
[0025] like Figure 4 As shown, specifically, both the first plug 3 and the second plug 6 include a cover plate 8 and a mounting block 9. The cover plate 8 and the mounting block 9 are interlocked, and a sealing gasket 4 is disposed between the cover plate 8 and the mounting block 9 to ensure the airtightness of the interior of the first plug 3 and the second plug 6. In this embodiment, the sealing gasket 4 is a silicone sheet with a thickness of 3mm and a Shore A hardness of 80.
[0026] Furthermore, a pressure head 7 is mounted on the mounting block 9 of the second plug 6. A cavity 10 is formed at the position of the mounting block 9 of the second plug 6 corresponding to the pressure head 7. The cavity 10 connects the workpiece 100 to be tested and the pressure head 7, facilitating the addition of gas or liquid into the workpiece 100 through the pressure head 7, and allowing the workpiece 100 to undergo a pressure burst test using air or hydraulic pressure. In addition, the sealing gasket 4 on the second plug 6 has a through hole that matches the inner hole of the workpiece 100, allowing gas or liquid in the cavity 10 to enter the workpiece 100.
[0027] Working principle: In use, the workpiece 100 to be tested is fitted into the protective sleeve 1, and the positions of the first plug 3 and the second plug 6 are adjusted so that they connect to both ends of the workpiece 100. Then, the positions of the first plug 3 and the second plug 6 are fixed and clamped by the cooperation between the limiting member 5 and the screw 2. The two ends of the installed workpiece 100 are sealed by the first plug 3 and the second plug 6. Liquid or gas is then injected into the workpiece 100 through the pressure head 7 using external equipment to perform the pressure burst test.
[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
