During the production process of grooved pipe fittings, in order to ensure product quality, it is often necessary to use a roundness tester to test the roundness of the inner diameter of the grooved pipe fittings. Nowadays, roundness testers are generally simply placed on the workbench without effective stabilization, which makes the roundness tester prone to movement during the testing process, affecting the accuracy of the test.

[0003] In the prior art, patent (CN216898844U) proposes a roundness detection device for the inner diameter of grooved pipe fittings, including a roundness detector body fixedly installed on a base. Multiple cavities are formed on the lower side wall of the base, each cavity containing a slidably connected screw. Each screw has a threaded sleeve threadedly connected to it, and each threaded sleeve is rotatably connected to its corresponding cavity. Multiple suction cups are fixedly installed at the lower end of the base, and a pressure adjustment mechanism is installed between each suction cup and its corresponding screw. A first worm gear is fixedly fitted at one end of each threaded sleeve outside the cavity. A drive mechanism is installed on the base, cooperating with the multiple first worm gears. This invention can directly adjust the pressure in the space between the piston and the worktable, thereby completing the engagement or disengagement of the piston and the worktable, making the assembly and disassembly of the device to the worktable easier.

[0004] However, in the aforementioned existing technology, after each suction cup is adsorbed, the internal air pressure is not easy to adjust, and the suction cup remains tightly adsorbed on the work surface, making it impossible to ventilate quickly. Summary of the Invention

[0006] To achieve the above objectives, this utility model provides a roundness detection device for the inner diameter of grooved pipe fittings, including a roundness detector body and a stabilizing mechanism. The stabilizing mechanism includes a base plate, multiple connecting rods, multiple anti-slip pads, a support assembly, multiple positioning assemblies, multiple telescopic assemblies, and multiple adsorption assemblies. Each adsorption assembly is fixedly connected to a corresponding telescopic assembly and is located at the lower end of the corresponding telescopic assembly.

[0008] Each of the positioning components includes a positioning plate and a universal ball. The universal ball is rotatably connected to the positioning plate and is located inside the positioning plate. The positioning plate is fixedly connected to the roundness detector body and is located below the roundness detector body.

[0009] Each of the telescopic components includes a sleeve, a spring, and a telescopic rod. The upper end of the telescopic rod is fixedly connected to the spring and is located at the lower end of the spring. The upper end of the spring is fixedly connected to the sleeve and is located on the inner top wall of the sleeve. The upper end of the sleeve is fixedly connected to the corresponding universal ball and is located on the periphery of the corresponding universal ball.

[0010] Each of the adsorption components includes a suction cup, a vent valve, and a mounting plug. The mounting plug is detachably connected to the vent valve and is located above the vent valve. The vent valve is fixedly connected to the suction cup and is located on one side of the suction cup. The suction cup is fixedly connected to the telescopic rod and is located at the lower end of the telescopic rod.

[0011] This utility model discloses a grooved pipe fitting inner diameter roundness detection device.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] This utility model provides a device for detecting the roundness of the inner diameter of grooved pipe fittings, including a roundness detector body 101 and a stabilizing mechanism 102. The stabilizing mechanism 102 includes a base plate 103, multiple connecting rods 104, multiple anti-slip pads 105, a support assembly 106, multiple positioning assemblies 107, multiple telescopic assemblies 108, and multiple adsorption assemblies 109. The support assembly 106 includes a support frame 110 and multiple support columns 111. Each positioning assembly 107 includes a positioning plate 112 and a universal ball 113. Each telescopic assembly 108 includes a sleeve 114, a spring 115, and a telescopic rod 116. Each adsorption assembly 109 includes a suction cup 117, a vent valve 118, and a mounting plug 119.

[0022] In this specific embodiment, each adsorption component 109 is fixedly connected to a corresponding telescopic component 108, the upper end of each telescopic component 108 is fixedly connected to a corresponding positioning component 107, each positioning component 107 is fixedly connected to the roundness detector body 101, the support component 106 is fixedly connected to the roundness detector body 101, each anti-slip pad 105 and the base plate 103 are fixedly connected to the roundness detector body 101, each connecting rod 104 is fixedly connected to the base plate 103, each support column 111 is fixedly connected to the support frame 110, the support frame 110 is fixedly connected to the roundness detector body 101, the universal ball 113 is rotatably connected to the positioning plate 112, the positioning plate 112 is fixedly connected to the roundness detector body 101, the upper end of the telescopic rod 116 is fixedly connected to the spring component 115, and the upper end of the spring component 115 is fixedly connected to the sleeve. The tube 114 is fixedly connected, and the upper end of the tube 114 is fixedly connected to the corresponding universal ball 113. The mounting plug 119 is detachably connected to the vent valve 118. The vent valve 118 is fixedly connected to the suction cup 117. The suction cup 117 is fixedly connected to the telescopic rod 116. The telescopic rod 116 and the spring 115 in the telescopic assembly 108 can provide good support and apply pressure to the suction cup 117 in the adsorption assembly 109 to better fit the workbench. The air pressure inside the suction cup 117 can be quickly adjusted through the setting of the vent valve 118 and the mounting plug 119. When using the device, the user only needs to place the roundness detector body 101 and insert the mounting plug 119 to stabilize the roundness detector body 101. This design solves the problem that after each suction cup 117 is adsorbed, the internal air pressure is not easy to adjust, and the suction cup 117 is still tightly adsorbed on the workbench and cannot be quickly ventilated.

[0023] In this configuration, each adsorption component 109 is located at the lower end of the corresponding telescopic component 108, the upper end of each telescopic component 108 is located below the corresponding positioning component 107, each positioning component 107 is located below the roundness detector body 101, the support component 106 is located on the periphery of the roundness detector body 101, each anti-slip pad 105 and the base plate 103 are located below the roundness detector body 101, each connecting rod 104 is located on both sides of the base plate 103, each telescopic rod 116 is connected to the corresponding collar through the spring member 115, and there is a limiting ring between the collar and the telescopic rod 116 to ensure that the telescopic rod 116 will not detach from the inner side of the sleeve 114 after moving downward.

[0024] Secondly, each of the support columns 111 is located below the support frame 110, which is located around the roundness detector body 101. The universal ball 113 is located inside the positioning plate 112, which is located below the roundness detector body 101. The sleeve 114 is fixedly connected to the universal ball 113, so the sleeve 114 can freely rotate below the corresponding positioning plate 112. In conjunction with the spring 115 and the telescopic rod 116, it can better adapt to changes in the shape of the workbench. When the roundness detector body 101 is not placed on the workbench, the horizontal line of the telescopic rod 116 and the corresponding suction cup 117 is lower than the height of each anti-slip pad 105. The purpose is to ensure that the telescopic rod 116 and the spring 115 can be compressed after being in contact with the ground, so as to provide better support for the suction cup 117.

[0025] Meanwhile, the upper end of the telescopic rod 116 is located at the lower end of the spring member 115, the upper end of the spring member 115 is located on the inner top wall of the sleeve 114, the upper end of the sleeve 114 is located on the periphery of the corresponding universal ball 113, the mounting plug 119 is located above the vent valve 118, the vent valve 118 is located on one side of the suction cup 117, the suction cup 117 is located at the lower end of the telescopic rod 116, and multiple connecting rods 104 are provided on both sides of the base plate 103. Each positioning plate 112 is fixedly connected to the base plate 103 through the corresponding connecting rod 104 to maintain the strength of the bottom frame and cooperate with multiple support columns 11. The support frame 110 and the roundness detector body 101 work together to provide better stability. When placing the roundness detector body 101, the mounting plugs 119 on each suction cup 117 need to be removed. The weight of the roundness detector body 101 itself will compress the suction cups 117 and the telescopic rod 116. After the position is stable, the mounting plugs 119 are reinstalled. At this time, the air pressure inside each suction cup 117 is one standard atmosphere, and there is little air inside, so it fits tightly against the workbench. After using the roundness detector body 101, each mounting plug 119 can be removed directly to quickly transfer the roundness detector body 101, which is convenient and fast.

[0026] In this embodiment, each telescopic rod 116 is connected to the corresponding collar via a spring 115, and a limiting ring is provided between the collar and the telescopic rod 116 to ensure that the telescopic rod 116 will not detach from the inner side of the sleeve 114 after moving downwards. The sleeve 114 is fixedly connected to the universal ball 113, so the sleeve 114 can freely rotate below the corresponding positioning plate 112. Combined with the spring 115 and the telescopic rod 116, it better adapts to changes in the shape of the workbench. When the roundness detector body 101 is not placed on the workbench, the horizontal line of the telescopic rod 116 and the corresponding suction cup 117 is lower than the height of each anti-slip pad 105. This is to ensure that the telescopic rod 116 and the spring 115 can be compressed after contact with the ground, providing better resistance to the suction cup 117. Each positioning plate 112 is fixedly connected to the base plate 103 via the corresponding connecting rod 104, maintaining the strength of the bottom frame. It also works in conjunction with multiple support columns 111 and the support frame 110 for enhanced stability. When placing the roundness detector body 101, the mounting plug 119 on each suction cup 117 needs to be removed. The weight of the roundness detector body 101 itself compresses the suction cup 117 and the telescopic rod 116. After stable placement, the mounting plug 119 is reinstalled. At this time, the air pressure inside each suction cup 117 is one standard atmosphere, with minimal internal air, allowing for close contact with the workbench surface. After using the roundness detector body 101, each mounting plug 119 can be directly removed for quick and easy transfer of the roundness detector body 101.

[0027] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
