[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. When performing a bending test on the tube to be tested, one end of the tube to be tested is fixed to the connector and the other end is blocked. The other end passes through the gap between the two mandrels and then through the first clamping member. The tube to be tested is clamped and fixed by the first clamping member. Gas is introduced into the tube to be tested through the connecting pipe. The motor drives the rotating shaft to rotate back and forth, so that the swing rod swings back and forth. The tube to be tested bends at the mandrel, thus realizing the bending test of the tube to be tested. The distance from the connector to the first clamping member is between 15cm and 40cm, which is relatively short and can meet the bending test requirements for short-sized tubes to be tested.

[0016] 2. When performing a bending test on a long tube, since the distance between the first clamping member and the connector is short, most of the long tube extends beyond the first clamping member. At this time, the end of the tube that extends beyond the first clamping member can pass through the second clamping groove and be clamped by the second clamping member, thereby enabling the bending test to be performed on the long tube near both ends. The second clamping groove is waist-shaped. When the tube is too long, it can be clamped by winding around the second clamping groove, which facilitates the testing of long tubes.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, this embodiment discloses a gas hose bending test device, including a housing 1. Inside the housing 1 are a power unit 11, a support 2, and a swing rod 3. A rotating shaft 12 is located on the side of the power unit 11, and a motor is installed inside the power unit 11. The motor can drive the rotating shaft 12 to rotate back and forth. The end of the rotating shaft 12 is fixed to the lower part of the swing rod 3. The rotating shaft 12 can drive the swing rod 3 to swing back and forth. A slider 4 is located on the side of the swing rod 3 facing the support 2, and a connecting piece 5 is installed on the side of the slider 4. The connector 5 is equipped with a first clamping member 6 on its side. The bracket 2 includes a vertical plate 22. A support plate 24 is provided on the side of the vertical plate 22. A connector 25 is fixed on the upper part of the support plate 24. A connecting pipe 100 is connected to the side of the connector 25. The connecting pipe 100 can be connected to an external air source. The first clamping member 6 is located above the connector 25 and is located in the same plane as the connector 25. Two core rods 7 are fixed on the side of the bracket 2. The core rods 7 are located between the first clamping member 6 and the connector 25.

[0024] When performing a bending test on the tube 8 to be tested, one end of the tube 8 to be tested is fixed to the connector 25 and the other end is blocked. The other end passes through the gap between the two mandrels 7 and then through the first clamping member 6. The tube 8 to be tested is clamped and fixed by the first clamping member 6. Gas is introduced into the tube 8 to be tested from the connecting pipe 100. The motor drives the rotating shaft 12 to rotate back and forth, so that the swing rod 3 swings back and forth. The tube 8 to be tested bends at the mandrel 7, thus realizing the bending test of the tube 8 to be tested. The distance between the connector 25 and the first clamping member 6 is between 12cm and 40cm, which is relatively short and can meet the bending test requirements of short-sized tubes 8 to be tested.

[0025] The first clamping member 6 includes a first clamping block 61 and a second clamping block 62. The first clamping block 61 is fixed to the connector 55. The first clamping block 61 and the second clamping block 62 are fixed by a first handle bolt 64. The first clamping block 61 and the second clamping block 62 can abut against each other to form a first clamping groove 63. The first clamping groove 63 has the same diameter as the tube 8 to be tested. There are two first handle bolts 64, which are symmetrically designed along the first clamping groove 63. The first handle bolts 64 can not only connect the first clamping block 61 and the second clamping block 62, but also facilitate the disassembly of the second clamping block 62, thereby facilitating the clamping operation of the tube 8 to be tested.

[0026] The connecting member 5 includes a support block 51 and a rotating block 52. The support block 51 is fixed to the slider 4, and the rotating block 52 is rotatably connected to the support block 51 through a bearing. The first clamping member 6 is fixedly connected to the rotating block 52. When the swing rod 3 swings, the first clamping member 6 will exert a force on the tube 8 to be tested. Therefore, the first clamping member 6 is designed to be rotatable, which can greatly reduce the risk of the force damaging the tube 8 to be tested, thereby improving the accuracy of the test results.

[0027] The swing rod 3 is provided with a second guide rail 31 on its side. The second guide rail 31 passes through the slider 4. The slider 4 can move along the second guide rail 31. The slider 4 and the second guide rail 31 are fixed by bolts. The connection method between the slider 4 and the second guide rail 31 is the prior art. Through the cooperation of the slider 4 and the second guide rail 31, the clamping operation of the tube 8 to be tested of different lengths can be realized, thereby meeting the bending test of the tube 8 to be tested of different lengths.

[0028] The swing rod 3 has a scale line 32 on its side along its length, and the connector 5 has a pointer 53 on its side, which is positioned toward the scale line 32. In this embodiment, the vertical distance from the connector 25 to the scale line 32 is zero is 10cm, so it is possible to test a short-sized tube 8 with a length of 20cm.

[0029] The vertical plate 22 is provided with a guide groove 23 corresponding to the mandrel 7. The mandrel 7 and the guide groove 23 are fixed by a nut. The two mandrels 7 can move along the guide groove 23 to move closer or further away from each other. The box 1 is provided with a first guide rail 13. The lower part of the vertical plate 22 is provided with a base 21. The base 21 is connected to the first guide rail 13. Through the above design, the bending test of the tube 8 to be tested can be facilitated.

[0030] The swing rod 3 is connected to a second clamping member 9 at the end away from the rotating shaft 12. The second clamping member 9 includes a third clamping block 91 and a fourth clamping block 92, which are fixed by a second handle bolt 94. The third clamping block 91 and the fourth clamping block 92 can abut against each other to form a second clamping groove 93. The second clamping groove 93 and the first clamping groove 63 are located in the same plane, and the second clamping groove 93 is waist-shaped. When a bending test is performed on a long tube 8, since the distance between the first clamping member 6 and the connector 25 is short, most of the long tube 8 extends beyond the first clamping member 6. At this time, the end of the tube 8 extending beyond the first clamping member 6 can pass through the second clamping groove 93 and be clamped by the second clamping member 9, thereby enabling the bending test to be performed on the long tube 8 near both ends. The second clamping groove 93 is waist-shaped. When the tube 8 is too long, it can be clamped by... Figure 2 As shown, the tube is clamped by winding at the second clamping groove 93, which facilitates the testing of long tubes to be tested 8.
