[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] like Figures 1 to 7 As shown, in one embodiment provided by the utility model, an air tightness test tool comprises: a frame 1, on the side wall of which a gas transmission device 2 is fixedly installed, and also comprises: a first driving member 3 and a supporting member 4, a slide rail 5 is installed on the side of the frame 1, and the supporting member 4 is slidably installed on the slide rail 5, and the first driving member 3 is installed at the end of the slide rail 5, and the output end of the first driving member 3 is connected to the supporting member 4, and the supporting member 4 is provided with a docking interface 6 for docking with a target to be inspected.

[0029] Specifically, the frame 1 is a mounting frame for installing the gas transmission equipment 2 and other devices. The gas transmission equipment 2 is a device for transmitting water and gas to the detection target. The gas outlet end of the gas transmission equipment 2 and the docking port 6 of the supporting member 4 are connected by a closed hose. A second driving member 7 is installed at the top of the frame 1, and a lifting frame 8 is installed at the output end of the second driving member 7. A slide rail 5 is installed on the lifting frame 8; the top and bottom ends of the lifting frame 8 are both flat plates, and the top and bottom ends of the lifting frame 8 are connected by four cylindrical rods arranged on the edge of the flat plate. A through groove is arranged at the bottom end of the lifting frame 8, and the top end of the inner wall of the docking port 6 on the supporting member 4 is a threaded structure 61, and the bottom end of the threaded structure 61 is arranged in the docking port 6 on the supporting member 4. A sealing ring 62 is provided, and the detection target has a sealed cavity inside, and the sealed cavity has an open structure (such as a gas cylinder). When it is necessary to perform an airtightness detection operation on the detection target, the first driving member 3 is started (the first driving member 3 is a device capable of linear reciprocating motion, such as an electric push rod, a cylinder, etc.) to push the supporting member 4 to slide out of the frame 1 on the slide rail 5, and the staff screws the detection target into the threaded structure 61 of the docking port 6, so that the threaded structure 61 of the docking port 6 seals the detection target and the supporting member 4, and after the detection target is screwed into the threaded structure 61 of the docking port 6, the port of the detection target and the sealing ring 62 are pressed against each other, further sealing the detection target and the supporting member 4. The supporting member 4 is sealed, and then the first driving member 3 is used to pull the supporting member 4 to slide into the frame 1 on the slide rail 5, and the second driving member 7 is started (the second driving member 7 is a device capable of linear reciprocating motion, such as: an electric push rod, a cylinder, etc.) to push the lifting frame 8, the supporting member 4 and the detection target until the detection target enters the water, and the gas transmission equipment 2 is started to transmit the gas to the detection target through a closed hose, and observe whether there are bubbles on the outer wall of the detection target. If bubbles are generated, it means that the air tightness is poor. If no bubbles are generated, it means that its air tightness meets the requirements. When the first driving member 3 pushes the supporting member 4 to slide on the slide rail 5, due to the lifting frame 8 A through groove is provided at the bottom end, so that the sealed hose slides in the through groove, so that the sealed hose will not affect the sliding of the supporting member 4. The first driving member 3 pushes the supporting member 4 to slide out of the frame, so that the space for placing the detection target is larger and will not be affected by the side wall of the frame, so that the detection target is connected to the docking port 6 on the supporting member 4 more conveniently, thereby improving the efficiency of the air tightness detection of the detection target. In the prior art, when the air tightness detection tool is used to perform air tightness detection on the container, it is necessary to connect the detection target with the gas transmission equipment 2, which requires connecting the detection target in the frame 1, but the space in the frame 1 is small, which makes the connection between the detection target and the transmission equipment more troublesome, thereby affecting the efficiency of the air tightness detection;In this embodiment, when the air tightness test of the detection target is required, the first driving member 3 pushes the supporting member 4 to slide out of the frame 1 on the slide rail 5, and then the detection target is connected to the docking port 6 on the supporting member 4, and then the first driving member 3 pulls the supporting member 4 to slide into the frame 1 on the slide rail 5, and then the detection target is put into water, and the gas supply operation is performed inside the detection target through the gas supply device 2, and it is observed whether there are bubbles on the outer wall of the detection target. If bubbles are generated, it means that the air tightness is poor, and if no bubbles are generated, it means that its air tightness meets the requirements. The first driving member 3 pushes the supporting member 4 to slide out of the frame, so that the space for placing the detection target is larger and will not be affected by the side wall of the frame, so that the detection target is more convenient to connect with the docking port 6 on the supporting member 4, thereby improving the efficiency of the air tightness test of the detection target. ;

[0030] In another embodiment provided by the utility model, the supporting member 4 is symmetrically provided with two grooves 9 about the docking interface 6, the supporting member 4 is symmetrically provided with two square grooves 10, the two square grooves 10 are connected to the corresponding grooves 9, each of the two grooves 9 is slidably installed with a tightening member 11, the two tightening members 11 and the inner walls of the corresponding grooves 9 are each connected by a first elastic member 12, each of the two square grooves 10 is slidably installed with a square plate 13, the two square plates 13 are connected to the corresponding tightening members 11, and the two square plates 13 are each provided with an inclined through groove 14, and the two inclined through grooves 14 are from one end close to the docking interface 6 to the far end One end of the two grooves 9 is tilted downward; two slide grooves 15 are symmetrically provided on both sides of the two grooves 9, and a clamping rod 16 is slidably installed in each of the four slide grooves 15. The two clamping rods 16 located on both sides of the same groove 9 are connected by a sliding round rod 17, and the two sliding round rods 17 both penetrate the inclined through groove 14, and the two sliding round rods 17 are slidably arranged between the inclined through groove 14; a plurality of clamping grooves 18 are evenly provided on the side walls of the four clamping rods 16 close to the docking port 6, and a limiting rod 19 is slidably installed in each of the clamping grooves 18, and each of the limiting rods 19 is connected to the inner wall of the corresponding clamping groove 18 through a second elastic member 20.

[0031] Specifically, after the staff screws the detection target into the threaded structure 61 of the docking interface 6, since the detection target, the supporting member 4 and the docking interface 6 are threadedly connected, the detection target may become loose during the process of transporting the detection target into the water. During the process of the staff screwing the detection target into the threaded structure 61 of the docking interface 6, the side wall of the detection target and the retaining member 11 are pressed against each other. When the detection target is gradually screwed into the relative interface 6, the detection target pushes the retaining member 11 to slide against one end of the inner side of the groove 9, and the retaining member 11 squeezes the first elastic member 12 (the first elastic member 12 is a component capable of telescopic reset, preferably a spring) , so that the first elastic member 12 is in a compressed state, and at the same time, the pressing member 11 drives the square plate 13 to slide toward one end of the inner side of the square groove 10. Since the square plate 13 is provided with an inclined through groove 14 which is inclined downward from one end close to the docking interface 6 to one end away from the docking interface 6, when the inclined through groove 14 on the square plate 13 slides toward one end of the inner side of the square groove 10, the inclined through groove 14 drives the sliding round rod 17 to slide toward one end close to the docking interface 6 (because the sliding round rod 17 is connected to the two clamping rods 16, the clamping rod 16 can only slide linearly in the slide groove 15, so that the clamping rod 16 is also limited by the slide groove 15, when the inclined through groove 14 slides toward one end of the inner side of the square groove 10 , the sliding round rod 17 is forced to slide toward one end close to the docking port 6 by the squeezing force of the inclined through groove 14), the sliding round rod 17 drives the clamping rod 16 to slide toward one end close to the docking port 6, and the clamping rod 16 drives the limiting rod 19 to slide toward one end close to the docking port 6, so that the limiting rod 19 is pressed against the outer wall of the detection target. Since the second elastic member 20 (the second elastic member 20 is an element capable of telescopic reset, preferably a spring) has a certain telescopic elastic force, each limiting rod 19 is synchronously pressed against the outer wall of the detection target, so that the placement of the detection target is more stable, and the stability of the detection of the detection target is improved; when the air tightness of the detection target is detected, After the test is completed, the second driving member 7 is started to pull the lifting frame 8, the supporting member 4 and the test target out of the water, and then the first driving member 3 drives the supporting member 4 and the test target to slide out of the frame. The staff screws the test target out of the docking port 6. Under the rebound action of the first elastic member 12, the tightening member 11 pops out from the groove 9. Synchronously, the square plate 13 also pops out from the square groove 10. The square plate 13 slides with the inclined through groove 14 and the sliding round rod 17, so that the clamping rod 16 and the limit rod 19 are separated from the outer wall of the test target, so that the test target can be smoothly taken out, which provides convenience for the next air tightness test of the test target.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
