However, different types of water pipes will inevitably encounter maintenance and renovation projects when used. Plumbers and electricians often use water pipe fasteners when renovating waterways and repairing water pipes.

[0003] However, most fasteners cannot effectively control the fixing force when fixing the water pipe. When the fixing force is small, the water pipe is easy to shake inside the fastener, and when the fixing force is large, it is easy to cause damage to the water pipe, which is a little inconvenient. Therefore, an adjustable fastener is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 2 , an adjustable fastener in this embodiment includes a base plate 1, a pad is fixed at the bottom of the base plate 1, and the friction between the base plate 1 and the ground can be increased by setting the pad, so that the support is more stable, two support plates 2 are fixed on the top of the base plate 1, lower mounting blocks 3 are fixed on the top of the two support plates 2, an upper mounting block 4 is fixed on the top of the lower mounting block 3, a prompt component 5 is arranged inside the lower mounting block 3, and the prompt component 5 is used to adjust the fastening force, a rotating rod 6 is threadedly connected to the top of the upper mounting block 4, a threaded strip is fixed on the outer surface of the rotating rod 6, and a threaded hole matched with the threaded strip is opened inside the upper mounting block 4, and the threaded hole and the threaded strip are arranged, so that when the rotating rod 6 is rotated, the rotating rod 6 will move simultaneously due to the extrusion of the thread.

[0022] In addition, a control block 7 is plugged into the top of the rotating rod 6, and a friction strip is fixed on the outer surface of the control block 7. Two plug-in blocks are fixed on the top of the rotating rod 6, and a plug-in groove matched with the plug-in block is opened at the bottom of the control block 7. Through the provided plug-in block and the plug-in groove, the control block 7 can be disassembled when the control block 7 is pulled upward, thereby improving the utilization of resources. A clamping plate 8 is provided between the prompt component 5 and the rotating rod 6. The clamping plate 8 is an arc-shaped plate. Sponge pads are fixed on the opposite sides of the two clamping plates 8. The provided sponge pads can effectively increase the friction between the pipeline and the clamping plate 8, and can effectively prevent damage to the pipeline when the pipeline is tightened.

[0023] Furthermore, the top clamping plate 8 is rotatably connected to the rotating rod 6, and a fixed bearing is fixed on the top of the top clamping plate 8. The interior of the fixed bearing is fixed to the outer surface of the rotating rod 6. Through the set fixed bearing, the clamping plate 8 that cannot rotate will not affect the rotation of the rotating rod 6. The bottom clamping plate 8 is fixed to the prompt component 5, and two positioning rods 9 are fixed on the top of the top clamping plate 8 and penetrate through the top of the upper mounting block 4. The positioning rods 9 are used to limit the rotation of the clamping plate 8, and a limiting block 10 is fixed on the top of the positioning rod 9.

[0024] In general, by rotating the rotating rod 6, the rotating rod 6 can push the top clamping plate 8 to move downward and cooperate with the bottom clamping plate 8 to clamp the pipe, and the sponge pad can effectively improve the fastening stability, making the whole more practical.

[0025] See also Figure 3 The prompt component 5 in this embodiment includes a connecting block 501, a return spring 502, a prompt rod 503 and a prompt strip 504. The interior of the lower mounting block 3 is fixed to the connecting block 501, and the connecting block 501 and the bottom clamping plate 8 are fixed with the return spring 502. The return spring 502 is a high-strength spring. The high-strength spring is set so that when the return spring 502 is squeezed, the return spring 502 will generate prestress, thereby ensuring the stability of the fastening. The bottom of the bottom clamping plate 8 is fixed to the prompt rod 503 that penetrates into the interior of the connecting block 501, and sliding blocks 505 are fixed on both sides of the prompt rod 503. A sliding groove that is slidably connected to the sliding block 505 is opened in the interior of the connecting block 501. The setting of the sliding block 505 and the sliding groove makes the sliding of the prompt rod 503 more stable. The outer surface of the prompt rod 503 is fixed to the prompt strip 504, and the prompt strip 504 is set to prompt that the fixing force is small.

[0026] In general, when the pipe is clamped and the rotating rod 6 continues to rotate, the return spring 502 will be squeezed, thereby increasing the force for fixing the pipe. When the fixing force is increased, the prompt rod 503 will move to the outside of the connecting block 501, so that the staff can judge the force for fixing the pipe through the prompt bar 504, making the whole more practical.

[0027] The working principle of the above embodiment is:

[0028] The pipe is placed between the lower mounting block 3 and the upper mounting block 4, and the pipe is located between the two clamping plates 8. At this time, the rotating rod 6 is rotated by rotating the control block 7, so that the rotating rod 6 drives the top clamping plate 8 to move downward due to the extrusion of the thread, and the top clamping plate 8 is restricted from rotating by the limit block 10, so that the rotation of the rotating rod 6 will not drive the top clamping plate 8 to rotate together. After the top clamping plate 8 moves downward to cooperate with the bottom clamping plate 8 to clamp the pipe, continuing to rotate the control block 7 will cause the rotating rod 6 to push the top clamping plate 8, the pipe, The bottom clamping plate 8 and the prompt rod 503 move downward and squeeze the reset spring 502, so that the reset spring 502 generates prestress. When the prompt rod 503 moves downward, a part of the prompt rod 503 moves to the outside of the connecting block 501, so that the staff can judge the force of fixing the pipeline according to the prompt strip 504, and the prestress of the reset spring 502 will push the bottom clamping plate 8 to move upward, thereby ensuring the stability of the pipeline fastening. The overall structure is simple, which makes the pipeline fastening force more controllable, making the whole more practical.
