When the counterweight block is reset, the swing block can rotate freely, so that the swing block can smoothly pass over the telescopic column, releasing the pulling force applied to the telescopic column, and allowing the counterweight block to accurately return to its initial position.

[0041] The surface of the support plate 11 is also provided with a lower positioning mechanism 7, and the lower positioning mechanism 7 includes a shell 71 fixed to the surface of the support plate 11, and a fourth spring 72 is installed on the top of the shell 71. A magnetic ring 73 is installed on the top of the fourth spring 72, and the magnetic ring 73 is magnetically connected to the bottom end of the metal tube 41.

[0042] First, the connecting tubes 32 are installed on both ends of the tube 31 to be tested. The surface of the connecting tube 32 is provided with an annular groove, which can effectively increase the friction and air tightness between the connecting tube 32 and the tube 31 to be tested, ensure the good connectivity between the tube 31 to be tested and the connecting tube 32, and prevent the connecting tube 32 from falling off. The metal tube 41 is installed on the contact ring 34 at the bottom end of the tube 31 to be tested, and then the metal tube 41 at the bottom end of the tube 31 to be tested is magnetically connected to the magnetic ring 73, and the bottom end of the tube 31 to be tested is fixed by the magnetic adsorption of the magnetic ring 73 and the metal tube 41; then the tube 31 to be tested is straightened, and the connecting tube 32 at the top of the tube 31 to be tested is clamped between the two positioning plates 52, and it is ensured that the top surfaces of the two positioning plates 52 are in contact with the bottom surface of the contact ring 34 at the top of the tube 31 to be tested, so that the tube 31 to be tested is installed. The whole installation process is simple and fast, which greatly reduces the labor of the detection personnel.

[0043] Example 2: This example is an explanation based on Example 1. For details, please refer to Figure 1-Figure 10 The support mechanism 1 also includes an electric telescopic rod 12 , which is installed on the top surface of the support plate 11 .

[0044] The surface of the support plate 11 is provided with an air pumping mechanism 2, which includes a pump body 21 slidably connected to the surface of the support plate 11, the pump body 21 is installed at the output end of the electric telescopic rod 12, and the air injection head 22 is installed at the bottom of the pump body 21. Two long rods 23 are symmetrically fixed at both ends of the pump body 21, and the long rods 23 are slidably connected to the inside of the support plate 11. A pressure head 24 is fixed at the upper end of each long rod 23, and an inner sliding rod 25 is slidably connected to the lower end of each long rod 23. The inner sliding rod 25 is elastically connected to the corresponding long rod 23 through a first spring 26, and a trigger block 27 is fixed to the top of the inner sliding rod 25, and the trigger block 27 is slidably connected to the side wall of the long rod 23. A positioning hook 28 is provided at the bottom of the inner sliding rod 25, and the bottom of the long rod 23 is rotatably connected to a swing block 29 through a torsion spring 292. A socket 291 is provided at the bottom of the swing block 29, and the positioning hook 28 is engaged with the corresponding socket 291.

[0045] The connection mechanism 3 further comprises a butt joint 33 fixed to the top surface of a resisting ring 34 at the top end of the tube 31 to be tested, and a fixing hoop 35 is sleeved on the outer wall of both ends of the tube 31 to be tested.

[0046] The upper positioning mechanism 5 also includes a limit strip 53 fixed to the end edge of the fixed cylinder 51, the fixed cylinder 51 is rotatably connected to a rotating shaft 54 ​​inside, a gear 55 is installed at the inner end of the rotating shaft 54, the gear 55 is rotatably connected to the inside of the support plate 11, a turntable 56 is fixed to the outer end of the rotating shaft 54, an anti-slip arm 57 is fixed to the cylindrical surface of the turntable 56, a third spring 58 is installed inside the support plate 11, a rack 59 is slidably connected inside the support plate 11, one end of the third spring 58 is installed at the end of the rack 59, and the gear 55 is meshingly connected to the rack 59, and a wedge block 591 is fixed to the side of the rack 59.

[0047] In order to further improve the connection stability and good air tightness between the tube to be tested 31 and the connecting tube 32, a fixing hoop 35 is installed on the surface of the tube to be tested 31. The fixing hoop 35 firmly binds the tube to be tested 31 to the connecting tube 32 to prevent the connecting tube 32 from falling off.

[0048] After the test tube 31 is installed, the electric telescopic rod 12 is started to push the pump body 21 to slide downward (as shown in the attached Figure 1 As shown, the entire device is placed vertically), the pump body 21 drives the gas injection head 22 to be inserted into the docking head 33, and injects gas into the tube 31 to be tested. The pump body 21 delivers gas at a certain power, and the tube 31 to be tested expands. The tester observes whether the tube 31 to be tested has leakage or the like.

[0049] When the pump body 21 slides downward, the long rod 23 drives the pressure head 24 to slide downward inside the support plate 11, and the pressure head 24 contacts the inclined surface of the wedge block 591. The downward sliding of the pressure head 24 pushes the wedge block 591 to slide, thereby driving the rack 59 to slide. The rack 59 compresses the third spring 58 and drives the gear 55 to rotate. The gear 55 drives the turntable 56 at the end of the fixed cylinder 51 to rotate through the rotating shaft 54. The turntable 56 drives the anti-slip arm 57 to swing. After the two anti-slip arms 57 rotate 90 degrees relative to each other, the limit bar 53 at the end of the fixed cylinder 51 blocks the anti-slip arm 57 to prevent the anti-slip arm 57 from continuing to rotate. The two anti-slip arms 57 contact the surface of the tube to be tested 31. When the pump body 21 injects gas into the tube to be tested 31, the anti-slip arm 57 is driven to swing to contact the tube to be tested 31, so as to prevent the tube to be tested 31 from popping out from between the two positioning plates 52 during the inflation process, thereby improving the stability of the fixing of the tube to be tested 31.

[0050] The device can also detect the pressure of the tube 31. The pump body 21 gradually increases the amount of gas pumped into the tube 31, thereby gradually increasing the internal pressure of the tube 31. The inspector observes and records the state of the tube 31 under different air pressures.

[0051] After the pressure test is completed, the electric telescopic rod 12 drives the pump body 21 to return, and the pump body 21 drives the gas injection head 22 to be pulled out of the docking joint 33, and at the same time drives the pressure head 24 to slide upward through the long rod 23, and the wedge block 591 loses the pressure of the pressure head 24. Under the push of the third spring 58, the rack 59 drives the wedge block 591 to reset, and at the same time, the rack 59 drives the gear 55 to reverse, and the gear 55 drives the turntable 56 to reverse through the rotating shaft 54, and rotates the anti-slip arm 57 to the initial position, thereby releasing the tube 31 to be tested, and the test personnel can easily remove the connecting mechanism 3, further improving the installation and removal speed and detection efficiency of the tube 31 to be tested.

[0052] Example 3: This example is an explanation based on Example 1. For details, please refer to Figure 1-Figure 10 The sealing mechanism 4 also includes a plurality of air leakage holes 42 that evenly penetrate the metal tube 41. A closed ring 43 is slidably connected inside the metal tube 41. The closed ring 43 blocks the inner end of the air leakage hole 42. An external pressure cylinder 44 is slidably connected inside the bottom end of the metal tube 41. Both ends of the connecting rod 45 are respectively fixed to the bottom surface of the closed ring 43 and the top surface of the external pressure cylinder 44. The external pressure cylinder 44 is elastically connected to the inside of the metal tube 41 through a second spring 46.

[0053] A stretching mechanism 6 is provided on the surface of the support plate 11, and the stretching mechanism 6 includes two rotating columns 61 symmetrically connected to the surface of the support plate 11, and a pressure plate 62 is fixed on each rotating column 61. The bottom surface of the end of the pressure plate 62 contacts the top surface of the contact ring 34 below the tube to be tested 31, and the bottom surface of each pressure plate 62 is rotatably connected to the top of a pull rod 63. An adjusting disk 64 is fixed to the end of each rotating column 61, and the adjusting disk 64 is rotatably connected to the inside of the support plate 11. A shift block 65 is fixed to the cylindrical surface of each adjusting disk 64.

[0054] The lower positioning mechanism 7 also includes two hook rods 74 symmetrically and slidably connected to the inside of the shell 71. The hook rods 74 are in a right-angle rod structure. The outer pressure cylinder 44 abuts against the upper ends of the two hook rods 74. A number of fifth springs 75 are symmetrically installed inside the shell 71, and the corresponding fifth springs 75 are installed on the sides of the hook rods 74.

[0055] A counterweight mechanism 8 is installed on the bottom surface of the support plate 11, and the counterweight mechanism 8 includes a counterweight block 81 slidably connected to the bottom surface of the support plate 11, and two connecting hooks 82 are symmetrically fixed on the top surface of the counterweight block 81. The two connecting hooks 82 are symmetrically slidably connected to the inside of the shell 71, and each connecting hook 82 is engaged with the bottom end of the corresponding hook rod 74. Two sixth springs 83 are symmetrically installed inside the counterweight block 81, and a telescopic column 84 is installed at the end of each sixth spring 83, and the telescopic column 84 protrudes from the surface of the counterweight block 81.

[0056] As the pump body 21 drives the long rod 23 to slide downward, the long rod 23 drives the swing block 29 at its bottom end to slide downward. At this time, the positioning hook 28 at the bottom end of the inner slide rod 25 is inserted into the insertion hole 291 at the bottom of the swing block 29, so that the swing block 29 cannot rotate. Therefore, during the descent of the swing block 29, the telescopic column 84 on the side of the counterweight block 81 is squeezed, and the telescopic column 84 is pressed into the counterweight block 81, so that the swing block 29 can smoothly pass the telescopic column 84 and continue to slide downward. When the telescopic column 84 slides into the counterweight block 81, the sixth spring 83 is compressed; at the same time, when the long rod 23 finishes sliding down, the trigger block 27 at the top of the inner slide rod 25 just contacts the dial block 65 on the adjustment disk 64.

[0057] The metal tube 41 installed on the bottom end of the tube 31 to be tested is slidably connected with a closed ring 43. Initially, the closed ring 43 blocks the air leakage hole 42 on the surface of the metal tube 41, so that the metal tube 41 is in a closed state. When the tube 31 to be tested is subjected to leak detection and pressure detection, the metal tube 41 is always closed. When the pressure detection is completed, the air pressure inside the tube 31 to be tested is further increased (greater than the maximum air pressure during the pressure detection). The gas thrust is sufficient to push the external pressure cylinder 44 at the bottom of the metal tube 41, so that the external pressure cylinder 44 slides out of the metal tube 41. During the downward sliding of the external pressure cylinder 44, the second spring 46 is stretched and the closed ring 43 is driven to slide downward through the connecting rod 45, thereby exposing the air leakage hole 42, so that the metal tube 41 is connected inside and outside. The air leakage hole 42 can discharge part of the gas inside the tube 31 to be tested, thereby balancing the internal air pressure of the tube 31 to be tested, and avoiding excessive pressure that may damage the tube 31 to be tested.

[0058] The device can also perform tensile testing on the tube 31 to be tested. The outer pressure cylinder 44 slides downward and also contacts and pushes the hook rod 74 inside the shell 71 to move. The two hook rods 74 slide toward the two ends of the shell 71, compressing the fifth spring 75 while releasing the engagement with the connecting hook 82 at its bottom end, releasing the connecting hook 82, and then the counterweight block 81 descends, driving the connecting hook 82 to descend, and at the same time pulling the pressing plate 62 through the pull rod 63 to rotate the rotating column 61 (when installing the tube 31 to be tested, the top surface of the contact ring 34 at the bottom end of the tube 31 to be tested contacts the bottom surface of the pressing plate 62), and the pressing plate 62 drives the entire blocking mechanism 4 to move downward by squeezing the contact ring 34 at the bottom end of the tube 31 to be tested, and the blocking mechanism 4 stretches the tube 31 to be tested downward, and the tester observes and records the state of the tube 31 to be tested. The rotating column 61 drives the adjusting disk 64 to rotate during the rotation process, and the adjusting disk 64 drives the shifting block 65 on its cylindrical surface to swing. At this time, the trigger block 27 resists the shifting block 65. Since the inner sliding rod 25 is elastically connected to the inside of the long rod 23 through the first spring 26, when the adjusting disk 64 drives the shifting block 65 to swing upward, the trigger block 27 drives the inner sliding rod 25 to slide upward, and then the shifting block 65 can pass over the trigger block 27.

[0059] After the stretching test is completed, the pump body 21 drives the long rod 23 to reset, and the long rod 23 drives the inner sliding rod 25 and the swing block 29 to move upward. During the rising process of the swing block 29, it contacts the bottom of the telescopic column 84, and drives the counterweight block 81 to rise and reset through the telescopic column 84. The counterweight block 81 pushes the pressure plate 62 to swing upward through the pull rod 63, and the pressure plate 62 drives the rotating column 61 to rotate. The rotating column 61 drives the dial block 65 to swing downward through the adjusting disk 64. When the pressure plate 62 contacts the contact ring 34 at the bottom end of the tube 31 to be tested again, the counterweight block 81 returns to the initial position, and the connecting hook 82 at the top of the counterweight block 81 is inserted into the shell 71 and re-engaged with the bottom end of the hook rod 74. The position of the fixed counterweight block 81; and the dial block 65 contacts and pushes the trigger block 27 downward, the trigger block 27 drives the inner slide rod 25 to slide downward, and the inner slide rod 25 compresses the first spring 26 while driving the positioning hook 28 at its bottom end to descend, and the positioning hook 28 is pulled out from the socket 291, and the swing block 29 can rotate freely. As the long rod 23 drives the swing block 29 to rise, the trigger block 27 passes over the adjusting disk 64, and the swing block 29 passes over the hook rod 74. Then, under the elastic force of the torsion spring 292, the swing block 29 is reset, and under the elastic force of the first spring 26, the inner slide rod 25 rises, driving the positioning hook 28 to reinsert into the socket 291, locking the swing block 29.

[0060] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
