Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically a pressure testing machine. Background Technology

[0002] A pressure testing machine, also known as an electronic pressure testing machine, is a device that uses electricity to perform pressure tests according to its testing functions. It is mainly used to evaluate the performance of materials under specific conditions, such as tensile and compressive properties. This equipment is widely used by manufacturers of both metallic and non-metallic materials and is a key tool for ensuring product quality and performance.

[0003] In existing testing equipment, when conducting quality inspections on various products, operators manually operate the clamping mechanism to firmly fix the product in place to prevent it from moving during subsequent testing. Then, by controlling the movement of the moving parts, the connecting parts fixedly connected to the air guide copper tube can be moved, making it easy to insert the product's air guide tube into the connecting groove on the connecting parts. Subsequently, by starting the test program, the air guide copper tube inflates the inside of the product to achieve product testing.

[0004] However, when testing products, the product's air guide tube is usually inserted into the connecting groove to allow gas to be filled into the product. However, due to the pressure during the filling process, the connection between the connecting groove and the air guide tube may experience slight deformation or displacement, resulting in gaps at the connection. This phenomenon may cause deviations in the test results and also cause gas leakage from the connector, resulting in a waste of gas resources. Utility Model Content

[0005] The purpose of this invention is to provide a pressure testing machine to solve the problem that the air guide tube and connector of the product mentioned in the background art may not be tightly connected.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pressure testing machine includes: a main body, a product mounted on the main body, an air guide pipe mounted on the product, a movable part mounted on the main body, a connecting part mounted on the movable part, and an air guide copper pipe mounted on the connecting part; and a sealing assembly mounted on the connecting part, comprising a fixing groove and an outer frame mounted on the connecting part, an elastic element mounted on the outer frame, a fixing plate mounted on the elastic element, the fixing groove mounted on the air guide pipe, and a rubber ring mounted on the connecting part. The sealing assembly is used to seal the air guide pipe. A guiding assembly mounted on the outer frame, comprising a guide plate mounted on the outer frame, and rollers mounted on the guide plate, is used for smooth connection of the air guide pipe.

[0008] Preferably, the sealing assembly further includes a placement groove disposed inside the outer frame, with two sets of placement plates symmetrically arranged inside the placement groove. A through groove is provided on the outer frame corresponding to the placement plate, and the through groove passes through the placement groove. The placement plate is movably disposed in the through groove and extends to the outside.

[0009] Preferably, the connector has a connecting groove inside, and the connecting groove extends through the outer frame, with the rubber ring placed inside the connecting groove.

[0010] Preferably, a semicircular ring is provided on one side of the placement plate, and a fixing plate is provided on the side of the semicircular ring away from the placement plate, and the fixing plate matches the fixing groove.

[0011] Preferably, a rotating component is provided at one end of the placement plate, a crank is rotatably connected to the rotating component, and a pull plate is rotatably connected to the side of the crank away from the rotating component.

[0012] Preferably, an elastic element is provided on the side of the pull plate near the outer frame.

[0013] Preferably, the guide assembly further includes multiple sets of connecting plates disposed inside the guide plate.

[0014] Preferably, a rotating cylinder is rotatably connected to the connecting plate, and a roller is fixedly connected to the outer side of the rotating cylinder.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] When the product needs to be tested, the moving part drives the connecting part to move towards the product, so that the air guide tube is inserted into the connecting groove, and the fixing groove is aligned with the fixing plate. The elastic force of the elastic element can drive the fixing plate to be firmly inserted into the fixing groove. This ensures that when the product is inflated, the air guide tube can be firmly locked in the connecting groove. The rubber ring can keep the air guide tube and the connecting groove sealed, effectively reducing gaps at the connection, so that the test can be carried out smoothly.

[0017] When the air guide tube is inserted into the connecting groove, because the connecting groove and the air guide tube are too closely matched, in order to prevent the air guide tube from getting stuck on the outside of the connecting groove, the setting of rollers and guide plates can speed up the process of the air guide tube being inserted into the connecting groove, thus making the process smoother.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] like Figure 1 - Figure 7 As shown, this application provides a pressure testing machine, including: a main body 1, a product 2 disposed on the main body 1, a gas guide pipe 6 disposed on the product 2, a movable part 5 disposed on the main body 1, a connecting part 4 disposed on the movable part 5, a gas guide copper pipe 3 disposed on the connecting part 4, and further including: a sealing assembly disposed on the connecting part 4, the sealing assembly including a fixing groove 7 and an outer frame 8, the outer frame 8 disposed on the connecting part 4, an elastic element 12 disposed on the outer frame 8, a fixing plate 20 disposed on the elastic element 12, the fixing groove 7 disposed on the gas guide pipe 6, and a rubber ring 18 disposed on the connecting part 4. The sealing assembly is used to seal the gas guide pipe 6.

[0029] Specifically, such as Figure 4 As shown, the sealing assembly also includes a placement groove 19 disposed inside the outer frame 8. Two sets of placement plates 21 are symmetrically arranged inside the placement groove 19. A through groove 23 is provided on the outer frame 8 corresponding to the placement plate 21, and the through groove 23 penetrates the placement groove 19. The placement plate 21 is movably disposed in the through groove 23 and extends to the outside.

[0030] Specifically, such as Figure 4 As shown, the connector 4 has a connecting groove 9 inside, and the connecting groove 9 penetrates the outer frame 8. The rubber ring 18 is set inside the connecting groove 9.

[0031] Specifically, such as Figure 5 As shown, a semicircular ring 17 is provided on one side of the placement plate 21, and a fixing plate 20 is provided on the side of the semicircular ring 17 away from the placement plate 21. The fixing plate 20 matches the fixing groove 7.

[0032] Specifically, such as Figure 5 As shown, a rotating component 22 is provided at one end of the placement plate 21, and a crank 11 is rotatably connected to the rotating component 22. A pull plate 10 is rotatably connected to the side of the crank 11 away from the rotating component 22.

[0033] Specifically, such as Figure 5 As shown, an elastic element 12 is provided on the side of the pull plate 10 near the outer frame 8.

[0034] A guide assembly is provided on the outer frame 8. The guide assembly includes a guide plate 13 provided on the outer frame 8 and a roller 16 provided on the guide plate 13. The guide assembly is used for the smooth connection of the air pipe 6.

[0035] Specifically, such as Figure 7 As shown, the guide assembly also includes multiple sets of connecting plates 15 disposed inside the guide plate 13.

[0036] Specifically, such as Figure 7 As shown, a rotating cylinder 14 is rotatably connected to the connecting plate 15, and a roller 16 is fixedly connected to the outer side of the rotating cylinder 14.

[0037] In this embodiment: by controlling the air guide tube 6 to be inserted into the connecting groove 9, the air guide tube 6 can be pre-positioned. At this time, the fixing groove 7 is aligned with the fixing plate 20. Through the elastic force of the elastic element 12, the fixing plate 20 can be firmly inserted into the fixing groove 7, thereby fixing the air guide tube 6. This can effectively prevent the air guide tube 6 from shaking during the test. With the setting of the rubber ring 18, the air guide tube 6 can be firmly inserted into the connecting groove 9, while improving the sealing effect at the connection between the connecting groove 9 and the air guide tube 6. Through the cooperation of the guide plate 13 and the roller 16, the air guide tube 6 can be guided when it is inserted into the connecting groove 9, so that the process of inserting the air guide tube 6 into the connecting groove 9 is smoother.

[0038] Specifically, when product 2 needs to be tested, product 2 is first placed in the testing area. The moving part 5 is controlled to move the connecting part 4 towards product 2, causing the air guide tube 6 to engage with the connecting groove 9 on the connecting part 4. This achieves pre-positioning of the air guide tube 6. At this time, the elastic force of the elastic part 12 can drive the fixing plate 20 into the fixing groove 7, thereby fixing the air guide tube 6. This effectively prevents the air guide tube 6 from shaking due to pressure when air is supplied, ensuring the air guide tube 6 remains stable. The rubber ring 18 ensures a tighter seal at the connection between the connecting groove 9 and the air duct 6. After the product 2 is inspected, pressing the pull plate 10 allows the fixing plate 20 to slide out of the fixing groove 7, facilitating the quick detachment of the connecting groove 9 and the air duct 6 by the staff. Because the air duct 6 and the connecting groove 9 are closely matched, the guide plate 13 allows the air duct 6 to quickly snap into the connecting groove 9, preventing jamming. The roller 16 further speeds up the process of the air duct 6 snapping into the connecting groove 9.
