[0035] Such as Figures 1 to 4As shown in the figure, the utility model discloses an auxiliary device for a pressure resistance test, which can install a specimen tube 600 and be connected to a pressure resistance device to assist in completing the pressure resistance test of metal pipes. The auxiliary device for the pressure resistance test includes a base 100, a sliding stopper 200 and a pressure resistance joint 400. Among them, the base 100 includes a base 110 and a side stopper 120. The side stopper 120 protrudes from the top of the base 110. An installation position is provided on the side stopper 120, which can be aligned with the specimen tube 600, and a through hole 122 communicating with the specimen tube 600 is opened at the installation position; the sliding stopper 200 is slidably connected to the base 110, and the position of the sliding stopper 200 can be adjusted according to the length of the specimen tube 600 to change the distance from the side stopper 120, enabling fine stepless adjustment, improving practicability and versatility to adapt to specimen tubes 600 with different lengths under different material specifications. When the sliding stopper 200 and the installation position respectively abut against both ends of the specimen tube 600, the sliding stopper 200 is selectively fixed to the base 110 and clamps and installs the specimen tube 600; at the same time, one end of the pressure resistance joint 400 communicates with the through hole 122, and the other end is used to connect to the pressure resistance device and input a pressurized medium into the specimen tube 600 to start the pressure resistance test and maintain pressure for a period of time, effectively recording the pressure resistance effect of the specimen tube 600; after the pressure resistance test is completed, the sliding stopper 200 can be adjusted again to remove the specimen tube 600. The auxiliary device for the pressure resistance test is simply designed, and each component is relatively independent, facilitating assembly and disassembly, with low manufacturing cost and simpler and more convenient operation for test personnel.

[0036] Specifically, the auxiliary device for the pressure resistance test includes an adjustment module 300. The adjustment module 300 includes a guide member 310 and a locking member 320. One end of the guide member 310 is fixedly connected to the side stopper 120, and the other end of the guide member 310 can pass through the sliding stopper 200 and be detachably connected to the locking member 320, specifically, it can be a threaded connection. The extending direction of the guide member 310 is parallel to the sliding direction of the sliding stopper 200 and the base 110, and the sliding stopper 200 slides relative to the side stopper 120 along the guide member 310. Exemplarily, the guide member 310 is a threaded guide rod, and the locking member 320 is a locking nut. The threaded guide rod cooperates with the locking nut, and by tightening the locking nut, the sliding stopper 200 and the side stopper 120 are clamped and fixed to the specimen tube 600; after the pressure resistance test is completed, the locking nut can be loosened and the specimen tube 600 can be removed.

[0037] Furthermore, a plurality of adjustment modules 300 are provided. The plurality of adjustment modules 300 are arranged at intervals along the circumference of the installation position, which can clamp the specimen tube 600 more evenly, making the pressure resistance test effect better. In this embodiment, there are 4 threaded guide rods and locking nuts respectively, and they are arranged in one-to-one correspondence. A torque wrench is used to adjust the locking nuts to more stably fix the specimen tube 600, and at the same time, the operation is more labor-saving.

[0038] In this embodiment, a first installation groove 121 is provided at the installation position. One end of the sample tube 600 is placed in the first installation groove 121, and a through hole 122 is provided at the bottom of the first installation groove 121. A second installation groove 210 is provided on the sliding stopper 200. The second installation groove 210 and the first installation groove 121 are both circular grooves and are coaxially arranged. The second installation groove 210 is used to place the other end of the sample tube 600. The first installation groove 121 and the second installation groove 210 limit both ends of the sample tube 600 at the same time, which can prevent the sample tube 600 from slipping and flying out, and improve the safety of the pressure test.

[0039] Optionally, sealing members 500 are respectively provided in the first installation groove 121 and the second installation groove 210. The side stopper 120 and the sliding stopper 200 can be in sealed contact with both ends of the sample tube 600 through the sealing members 500, so as to prevent the end of the sample tube 600 from leaking the pressurized medium and affecting the result of the pressure test. By adding the sealing members 500, the processing requirements for the base 100 and the sliding stopper 200 of the pressure test auxiliary device can be reduced, the pressure test auxiliary device is simple to process, and the manufacturing cost can be further saved.

[0040] Specifically, the base 110 is provided with a trapezoidal groove 111. The bottom of the trapezoidal groove 111 is the large end of the trapezoid, and the opening of the trapezoidal groove 111 is the small end of the trapezoid. The sliding stopper 200 is provided with a trapezoidal sliding portion 220. The trapezoidal sliding portion 220 is slidably placed in the trapezoidal groove 111, so that the sliding stopper 200 is stably slidably connected to the base 110, and the sliding stopper 200 is prevented from disengaging from the base 110 upward and affecting the installation of the sample tube 600. It can be understood that the base 110 can be provided with a groove-shaped track of any shape and corresponding to the sliding portion of the sliding stopper 200, as long as it can stably cooperate with the sliding structure.

[0041] Furthermore, the pressure test auxiliary device includes a high-pressure hose. The pressure-resistant connector 400 connects the pressure test auxiliary device to the pressure outlet of the pressure-resistant equipment through the high-pressure hose, which is more convenient to connect and saves space occupancy. Exemplarily, the high-pressure hose can pass a pressurized medium that is gas or liquid.

[0042] In this embodiment, when the pressurized medium is liquid, the base 110 is provided with a diversion hole 112. A plurality of diversion holes 112 are arranged at intervals along the sliding direction of the sliding stopper 200 and the base 110, which is convenient for the pressure test auxiliary device to discharge and recycle the leaked pressurized medium.

[0043] Furthermore, since the pressure withstand test auxiliary device is placed on the operating table, the contact between the base 110 and the operating table may affect the discharge of the pressurized medium in the diversion hole 112. To better discharge and recover the leaked pressurized medium, a diversion groove 113 is provided at the bottom of the base 110. The diversion hole 112 is communicated with the diversion groove 113, which can provide a discharge space for the leaked pressurized medium. Alternatively, a recovery pipe can be arranged in the diversion groove 113 and communicated with the diversion hole 112 to realize the rapid recovery and utilization of the pressurized medium without affecting the stability of the placement of the pressure withstand test auxiliary device.

[0044] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
