[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0020] Example:

[0021] refer to Figures 1-4The fixture shown includes a side plate 1, with a tube insertion base 2 and an adjusting seat 3 respectively on both sides of the side plate 1. A water injection pipe 4 is fixedly connected to one side of the tube insertion base 2, and the end of the water injection pipe 4 passes through the tube insertion base 2 and is fitted with a sealing sleeve 9. A pipe clamping assembly is provided on the other side of the tube insertion base 2. The pipe clamping assembly includes an upper clamping plate 501, a lower clamping plate 502 and a bolt assembly 503. The adjusting seat 3 is slidably connected to the side plate 1. A cylinder 6 and a support seat 7 are fixedly connected to the adjusting seat 3. A tightening assembly is fixedly connected to the piston rod of the cylinder 6. The side plate 1 has multiple mounting holes, and the adjusting seat 3 is fixedly connected to the side plate 1 by a screw.

[0022] An inverted buckle is provided at the end of the water injection pipe 4 that passes through the insertion base 2. The sealing sleeve 9 is fitted onto the water injection pipe 4. The inverted buckle structure prevents the sealing sleeve 9 from slipping off. The upper clamping plate 501 and the lower clamping plate 502 are both slidably connected to the insertion base 2. The insertion base 2 can guide the clamping action of the upper clamping plate 501 and the lower clamping plate 502. The upper clamping plate 501 and the lower clamping plate 502 are fixed and clamped to the pipe fitting by the bolt assembly 503.

[0023] Both the upper clamping plate 501 and the lower clamping plate 502 are provided with arc-shaped grooves. The arc-shaped grooves are used for contour positioning and clamping of the pipe to be tested. Multiple silicone strips 504 are fixedly connected in the arc-shaped grooves of the upper clamping plate 501 and the lower clamping plate 502. The silicone strips 504 can avoid damage to the pipe caused by rigid clamping and improve the clamping effect.

[0024] The support base 7 is fixedly connected to the insertion base 2. A U-shaped groove is formed on the support base 7 to support and place the tubing. The clamping assembly includes a disc base 801 and a sealing plug 802. A cylinder 6 drives the disc base 801 to slide and translate, achieving the sealing action. The sealing plug 802 seals the end of the tubing. The sealing plug 802 is a silicone plug, and its sidewall has multiple annular protrusions to improve the sealing performance when inserted into the tubing.

[0025] The working principle of this utility model is as follows: Before use, select a sealing sleeve 9 that corresponds to the inner diameter of the pipe fitting according to the thickness of the pipe fitting and install it at the end of the water injection pipe 4; adjust the distance between the adjusting seat 3 and the insertion base 2 according to the length of the pipe fitting (this distance is greater than the length of the pipe fitting to ensure that the pipe fitting can be put in and taken out normally), and fix the adjusting seat 3 with a screw by selecting the mounting hole.

[0026] In use, one end of the pipe fitting is inserted along the sealing sleeve and abutted against the insertion base 2. Then, the upper clamping plate 501 and the lower clamping plate 502 are clamped to the outer wall of the pipe fitting by the bolt assembly 503. The other end of the pipe fitting is located on the support seat 7. The piston rod of the cylinder 6 extends out and the sealing plug 802 seals the end of the inserted pipe fitting. After sealing both ends of the pipe fitting, water is injected into the pipe fitting through the water injection pipe 4 for a water injection test.

[0027] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
