In the conventional pipe tensile test device, in order to ensure that the second clamp 7 has a sufficient stroke, the length of the first support rod 11 is often set to be longer, but the height of the pipe tensile test device is higher, and the occupied space is larger. In this application, when need not to carry out tensile test, make first telescopic link 3 relatively first bracing piece 11 convex distance shorter, the interval between first anchor clamps 6 and second anchor clamps 7 this moment is less, and whole tubular product testing device height is lower and the volume is less for tubular product testing device is comparatively portable. When tensile test is needed, the first telescopic rod 3 is pulled to enable the first telescopic rod 3 to be longer in protruding distance relative to the first supporting rod 11, the height of the pipe testing device is higher at the moment, and the second clamp 7 has enough moving stroke. The working procedure for carrying out the tensile test is as follows: the first clamp 6 and the second clamp 7 are used for clamping two ends of the pipe respectively, the driving piece 9 is started, so that the driving piece 9 drives the sliding seat 5 to move, the second clamp 7 moves towards the direction far away from the second clamp 7, and the pipe is stretched. After the tensile test is completed, the user controls the driving member 9 again, so that the driving member 9 drives the sliding base 5 to move the second clamp 7 to a direction close to the first clamp 6. The drive 9 is embodied as a hydraulic electric cylinder.
As shown in fig. 1, the portable tube tensile testing apparatus further includes a second telescopic rod 12, a second limiting member 13 and a second support rod 14 fixed to the base 1, one end of the second telescopic rod 12 is slidably connected to the second support rod 14, the second limiting member 13 is used for limiting the second telescopic rod 12 to slide relative to the second support rod 14, the other end of the second telescopic rod 12 is connected to one end of the fixing base 8 far away from the first telescopic rod 3, and one end of the sliding base 5 far away from the first telescopic rod 3 is slidably connected to the second telescopic rod 12. The first support rod is further used for supporting the sliding seat 5 and the fixed seat 8, so that the stability of the invention is improved.
As shown in fig. 1 and fig. 2, the first telescopic rod 3 includes a first telescopic section 31, a second telescopic section 32 and a third limiting member 33, one end of the first telescopic section 31 is slidably connected to the first support rod 11, the other end of the first telescopic section 31 is slidably connected to one end of the second telescopic section 32, the fixing seat 8 is connected to one end of the second telescopic section 32 away from the first telescopic section 31, and the third limiting member 33 is configured to limit the second telescopic section 32 from sliding relative to the first telescopic section 31; the fixing base 8 includes fixed part 81 and with fixed part 81 sliding connection's sliding part 82, the moving direction of sliding part 82 is perpendicular to the moving direction of the flexible section 32 of second, fixed part 81 with the flexible section 32 of second is connected, driving piece 9 set up in sliding part 82, driving piece 9's output with the connection can be dismantled to slide 5. The moving direction of the first telescopic section 31 relative to the first support rod 11 and the moving direction of the second telescopic section 32 relative to the first telescopic section 31 are set as the longitudinal direction. The conventional pipe tensile test device needs a reserved space between the fixed seat 8 and the sliding seat 5 to accommodate the driving part 9, so that the occupied longitudinal space is large. In the present invention, when the tensile test is not required, the output end of the driving member 9 is no longer connected to the sliding base 5, and the sliding portion 82 is pushed laterally so that the driving member 9 is no longer located between the fixing portion 81 and the sliding base 5. Subsequently, the second telescopic section 32 is pulled to enable the second telescopic section 32 to protrude a short distance relative to the first telescopic section 31, and the driving member 9 is located at the side end of the sliding seat 5, so that the longitudinal space occupied by the invention is reduced, and the structure of the invention is more compact and portable.

When a tensile test is required, the second telescopic section 32 is pulled to enable the second telescopic section 32 to protrude a longer distance relative to the first telescopic section 31, then the sliding portion 82 is pulled transversely to enable the driving member 9 to move transversely, and the second connecting rod 52 is inserted into the connecting ring 91 of the driving member 9 while the driving member 9 moves, so that the driving member 9 is connected with the sliding base 5.
As shown in fig. 1, the first restriction member 4 includes a pipe clamp 41 provided at a connection of the first support rod 11 and the first telescopic rod 3, and a screw 42 for locking the pipe clamp 41. When the first telescopic rod 3 needs to slide relative to the first support rod 11, the screw 42 is not locked with the pipe clamp 41; when the first telescopic rod 3 needs to be fixed relative to the first support rod 11, the pipe clamp 41 is locked by the screw 42, and the pipe clamp 41 drives the first support rod 11 to tightly clamp the first telescopic rod 3, so that the first telescopic rod 3 cannot move.
