[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1

[0024] Reference Figure 1-3 , a pressure test clamping device, comprising a base 1, wherein:

[0025] A groove 2 is provided at the upper end of the base 1, and the groove 2 is used to place the pipe fittings to be clamped. A rubber pad is provided in the groove 2, and the rubber pad is used to reduce the extrusion strength between the pipe fittings and the inner wall of the groove 2. A guide plate 3 is fixedly connected to the upper end of the base 1, and a scale is provided on the guide plate 3. The scale is convenient for knowing the height of the movable frame 4 moving in the vertical direction. The movable frame 4 is slidably plugged on the guide plate 3. The upper end of the base 1 is connected to a lifting mechanism for adjusting the height of the movable frame 4. The movable frame 4 is rotatably connected to a squeezing mechanism 6, and the movable frame 4 is connected to a screw rod for adjusting the height of the squeezing mechanism. The fixing mechanism 7 for fixing the pipe fittings is used to adjust the height of the movable frame 4 through the lifting mechanism according to the diameter of the pipe fittings. The movable frame 4 drives the squeezing mechanism 6 to move and adjust the height of the squeezing mechanism 6. When the pipe fittings are pressed, the pipe fittings are placed on the groove 2, and the squeezing mechanism 6 is rotated. The bottom end of the squeezing mechanism 6 contacts the upper end of the pipe fittings and squeezes the upper end of the pipe fittings. The squeezing mechanism 6 is squeezed and fixed by the fixing mechanism 7. The squeezing mechanism 6 squeezes the pipe fittings, thereby fixing the pipe fittings. It is convenient to manually fix the pipe fittings, and the pipe fittings are simply fixed.

[0026] The fixing mechanism 7 includes a threaded rod 71, which is fixedly connected to the movable frame 4. A groove column 72 is threadedly connected to the threaded rod 71. The bottom end of the groove column 72 can contact the extrusion mechanism 6. When the extrusion mechanism 6 is fixed, the groove column 72 is manually rotated. After the groove column 72 is rotated, under the guide limit of the threaded rod 71, the groove column 72 moves downward, and the bottom end of the groove column 72 contacts the upper end of the extrusion mechanism 6 and extrudes the extrusion mechanism 6. After the extrusion mechanism 6 is pressed, the pipe fitting is squeezed and fixed, which is convenient for manual fixation of the pipe fitting and simple to fix the pipe fitting.

[0027] The lifting mechanism includes a threaded tube, which is fixedly connected to the upper end of the base 1. A lifting member 5 is threadedly connected to the threaded tube. The lifting member 5 is a screw lifting member. A threaded hole is provided on the movable frame 4. The lifting member 5 cooperates with the threaded hole. When the movable frame 4 is adjusted, the lifting member 5 is rotated. After the lifting member 5 is rotated, the movable frame 4 moves in the vertical direction to adjust the height of the movable frame 4.

[0028] Working process: according to the diameter of the pipe fitting, the lifting member 5 is rotated. After the lifting member 5 is rotated, the movable frame 4 moves in the vertical direction, and the height of the movable frame 4 is adjusted. The movable frame 4 drives the extrusion mechanism 6 to move, and the height of the extrusion mechanism 6 is adjusted. When the pipe fitting is pressed, the pipe fitting is placed on the groove 2, and the extrusion mechanism 6 is rotated. The bottom end of the extrusion mechanism 6 contacts the upper end of the pipe fitting and squeezes the upper end of the pipe fitting. The groove column 72 is manually rotated. After the groove column 72 is rotated, under the guide limit of the threaded rod 71, the groove column 72 moves downward, and the bottom end of the groove column 72 contacts the upper end of the extrusion mechanism 6 and squeezes the extrusion mechanism 6. After the extrusion mechanism 6 is pressed, the pipe fitting is squeezed and fixed, which is convenient for manual fixation of the pipe fitting, and the pipe fitting is simply fixed.

[0029] Example 2

[0030] When the pipe fitting is squeezed and fixed by the squeezing mechanism 6, since the surface of the pipe fitting is arc-shaped, after the squeezing mechanism 6 contacts the pipe fitting, relative sliding between the squeezing mechanism 6 and the pipe fitting is likely to occur, thereby reducing the fixing effect of the squeezing mechanism 6 on the pipe fitting. Figure 4 As another preferred embodiment of the utility model, the difference from embodiment 1 is that the extrusion mechanism 6 includes a rotating plate 61, the rotating plate 61 is rotatably connected to the movable frame 4, the rotating plate 61 can contact the bottom end of the groove column 72, the bottom end of the rotating plate 61 is fixedly connected to a connecting rod 62, the end of the connecting rod 62 away from the rotating plate 61 is fixedly connected to an arc plate 63, the bottom end of the arc plate 63 is fixedly connected to an elastic pad 64, the elastic pad 64 is a sponge pad, a through hole is opened on the elastic pad 64, and an anti-slip pad 65 is connected to the through hole to prevent slipping. The pad 65 is a non-slip rubber pad. When the pipe fitting is squeezed and fixed, the rotating plate 61 squeezes the arc plate 63 through the connecting rod 62. The concave surface of the arc plate 63 fits with the upper end of the pipe fitting. Since the arc plate 63 is arc-shaped, it fits better with the upper end of the pipe fitting. The arc plate 63 contacts the pipe fitting through the elastic pad 64 and the non-slip pad 65. The non-slip pad 65 increases the friction between the pipe fitting and the concave surface of the arc plate 63. When the pipe fitting is squeezed and fixed by the arc plate 63, relative rolling will not occur between the arc plate 63 and the pipe fitting, thereby improving the fixing effect of the pipe fitting.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
