Specific embodiments
[0020] The following details the embodiments of the present utility model. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.
[0021] Please refer to Figures 1 to 6 , the present utility model provides a positive three-way airtightness test tooling, including two side rods 101 and a main rod 102. Through the foregoing solution, the technical problem that in the prior art, during the testing process, the tester needs to manually fix the product to be tested throughout the process, which extremely easily increases the burden on the tester's arm, thus causing the product to be tested to become loose, thereby reducing the passing rate of outgoing products, and at the same time, it is also easy to cause leakage is solved.
[0022] For this specific embodiment, one end of the side rod 101 is provided with an adjusting rod 103, and the other end of the side rod 101 is provided with a fixing ring 104. A threaded sleeve 105 is rotatably arranged in the fixing ring 104. Two limiting rings 106 are arranged on the threaded sleeve 105. A first screw rod 107 is arranged in the threaded sleeve 105. One end of the first screw rod 107 is provided with a disc 108, and a rubber pad 109 is arranged on the end face of the disc 108. Both ends of the main rod 102 have adjusting grooves 110. The adjusting rod 103 is slidably connected to the main rod 102 and is located in the corresponding adjusting groove 110. The two side rods 101 are symmetrically arranged at both ends of the main rod 102 respectively. By connecting and cooperating with the rubber pad 109 through the disc 108 and the first screw rod 107, and using the disc 108 to press the workpiece, the inside of the workpiece is filled with gas to make the gas reach a predetermined pressure, so as to detect whether there is a leakage phenomenon in the workpiece, thereby improving the qualified rate of the positive tee when leaving the warehouse and eliminating the leakage phenomenon after the positive tee leaves the warehouse; making users more assured when using the product.
[0023] Wherein, the two limiting rings 106 respectively abut against the fixing ring 104 and are symmetrically arranged at both ends of the fixing ring 104. By arranging the two limiting rings 106, it is convenient for the threaded sleeve 105 to rotate by itself, and at the same time, it prevents the threaded sleeve 105 from completely detaching from the fixing ring 104.
[0024] Secondly, one end of the threaded sleeve 105 is provided with a rotating disc 111. A plurality of rotating rods 112 are arranged on the rotating disc 111. A protective sleeve 113 is arranged on the rotating rod 112. By means of the rotating disc 111, it is convenient to rotate the threaded sleeve 105, thus playing a role in saving effort. At the same time, under the action of the protective sleeve 113, it is convenient to protect the user's hand.
[0025] Thirdly, the other end of the first screw rod 107 is provided with a protective member. The protective member includes a second screw rod 114 and a protective block 115. One end face of the protective block 115 has a rounded edge 116. The other end of the first screw rod 107 has a first thread groove 117. The second screw rod 114 is fixedly connected to the protective block 115 and is located on the other end face of the protective block 115. The second screw rod 114 is threadedly connected to the first screw rod 107 and is located in the first thread groove 117. And the protective block 115 abuts against the other end of the first screw rod 107. By providing the rounded edge 116 on the end face of the protective block 115, it is convenient to protect the user's palm, thus avoiding scratches on the user caused by the sharp surface.
[0026] In addition, a limiting member is provided at one end of the fixing ring 104. The limiting member includes a support ring 118 and a plurality of support rods 119. A plurality of limiting strips 120 are provided on the inner side of the support ring 118. A plurality of limiting grooves 121 are provided on the outer side of the first screw 107. The support ring 118 is fixedly connected to the corresponding support rod 119 and is located at one end of the plurality of support rods 119. The support ring 118 is also sleeved on the first screw 107. The limiting strips 120 are located in the limiting grooves 121. The plurality of support rods 119 are respectively fixedly connected to the fixing ring 104 and are located at one end of the fixing ring 104. The arrangement of the limiting strips 120 and the limiting grooves 121 facilitates the limitation of the first screw 107, thereby preventing the first screw 107 from rotating along with the rotation of the threaded sleeve 105, and further ensuring that the first screw 107 can horizontally push the disc 108, so as to ensure that gas leakage is avoided while applying pressure, and then improving the effect of the airtightness test.
[0027] Meanwhile, adjusting members are provided at both ends of the main rod 102. The adjusting member includes a rotating ring 122 and a third screw 123. A knob 124 is provided at one end of the third screw 123. A second threaded groove 125 is provided in the adjusting rod 103. The rotating ring 122 is fixedly connected to the third screw 123 and is sleeved on the third screw 123. The rotating ring 122 is also rotatably connected to the main rod 102 and is located at one end of the main rod 102. The third screw 123 is threadedly connected to the adjusting rod 103 and is located in the second threaded groove 125. By rotating the third screw 123, the third screw 123 is threadedly connected to the adjusting rod 103, and the adjusting rod 103 slowly moves under the action of the second threaded groove 125, so that the disc 108 moves away from the main rod 102, and thus it is convenient to make the tooling applicable to different models of positive tee pipes.
[0028] When using the present utility model, by aligning the two pipes arranged at 90° in the positive three-way pipe with the two discs 108 of the tooling, and using the rubber pad 109 to seal the two pipes, while rotating the rotating disc 111, the rotating disc 111 drives the threaded sleeve 105 to rotate under the action of the limiting ring 106, and the first screw rod 107 moves horizontally under the action of the threaded sleeve 105 and the limiting strip 120, so as to push the disc 108 to move towards the positive three-way pipe, thereby improving the sealing performance between the rubber pad 109 and the positive three-way pipe. The third pipe is used to introduce gas to fill the inside of the positive three-way with gas to reach a predetermined pressure, so as to detect whether there is a leakage phenomenon in the workpiece. Then, the gas leakage detection device is used to detect the gas leakage degree of the positive three-way pipe. In this way, it solves the technical problem that in the prior art, during the testing process, the tester needs to manually fix the product to be tested throughout the process. This fixing method is extremely likely to increase the burden on the tester's arm, resulting in the loosening of the product to be tested, thereby reducing the passing rate of outgoing products. At the same time, it is also likely to cause leakage situations.
[0029] The above-disclosed is only a preferred embodiment of the present utility model. Of course, it cannot be used to limit the scope of the rights of the present utility model. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present utility model still fall within the scope covered by the utility model.
