They are characterized by a wide variety of specifications, different performances and uses, and a high degree of standardization, serialization, and generalization. Fasteners are the most widely used basic mechanical parts and are in great demand. Fasteners are currently used in the pipeline industry, but the existing fasteners for pipelines are mostly fixed, so the applicable pipe diameter is relatively single, and pipes of different diameters cannot be fixed.

[0003] According to the Chinese utility model disclosure CN218780903U, a conveniently adjustable fastener includes two fastening plates, each of which is fixedly connected to two clamping plates on its outer surface, each of which is provided with bolt holes on its left side, and each group of bolt holes is threadedly connected to a connecting rod on its inner wall. The device is provided with a connecting rod, a bolt hole and a limit plate, and uses the rotating limit plate as a power source, and is combined with the threaded connection between the connecting rod and the bolt hole, so that the clamping plate drives the fastening plate to clamp the pipeline, and at the same time cooperates with the rubber pad to avoid the loosening of the pipeline when clamped, so as to solve the problems mentioned above that the existing fasteners have poor fastening effect, slow fastening and cumbersome operation. However, the pipe diameter that this setting can be applied to is relatively single, and it cannot fix pipes of different diameters. Therefore, in view of this problem, how to design a conveniently adjustable fastener has become a problem that we currently need to solve. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a fastener that is easy to adjust.

DETAILED DESCRIPTION

[0018] 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.

[0019] Refer to the instruction manual Figure 1-3 ,like Figure 1 As shown, a conveniently adjustable fastener of an embodiment of the utility model comprises an upper support plate 1, one side of which is hingedly connected to an upper fixing plate 2, such as Figure 2 As shown, one end of the upper fixed plate 2 is hinged with an upper movable plate 3, the interior of the upper movable plate 3 is slidably connected with a fastening bolt 4, the outer side of the fastening bolt 4 is threadedly connected with a fastening nut 5, the bottom end of the fastening bolt 4 is fixedly installed with a bottom plate 6, the interior of the bottom plate 6 is sleeved with a first shaft rod 7, one end of the first shaft rod 7 is fixedly installed with a lower movable plate 8, the bottom plate 6 is rotatably connected to the interior of the lower movable plate 8, and one side of the lower movable plate 8 is hinged with a lower fixed plate 9, the upper fixed plate 2 and the lower fixed plate 9 are both set in two, and are axially symmetrically arranged with respect to the vertical center line of the upper support plate 1, as shown in FIG. Figure 1 As shown, a lower support plate 10 is hingedly connected to one end of the lower fixing plate 9 , and an anti-slip member 11 is fixedly installed on the inner side of the lower fixing plate 9 .

[0020] When the pipe is tightened, the upper support plate 1 and the lower support plate 10 are placed on both sides of the pipe, and the upper fixing plate 2 and the lower fixing plate 9 on both sides are merged and contacted with the pipe, the bottom plate 6 is rotated to enter the interior of the upper movable plate 3, and the tightening nuts 5 are slightly tightened to connect the upper fixing plates 2 and the lower fixing plates 9 on both sides. At this time, the angle and position of the upper fixing plate 2 and the lower fixing plate 9 are adjusted, and the tightening nuts 5 on both sides are tightened to fix the pipe, and the anti-slip parts 11 on the inner sides of the upper fixing plate 2 and the lower fixing plate 9 are in contact with the pipe, thereby increasing friction and preventing loosening and slipping. Since the upper fixing plate 2 and the lower fixing plate 9 can both be flipped, the diameter can be conveniently adjusted, and the contact position with the pipe can also be arbitrarily adjusted, so that the flipping angle of the upper fixing plate 2 and the lower fixing plate 9 can be flexibly changed to tighten pipes of different diameters, thereby achieving the purpose of being able to tighten pipes of various diameters.

[0021] Further, such as Figure 1 As shown, the inner thread of the upper support plate 1 is connected with an adjusting screw 12, the top of the adjusting screw 12 is fixedly mounted with a handle 13, and the bottom of the adjusting screw 12 is sleeved with an arc-shaped reinforcement plate 14, as shown in FIG. Figure 3 As shown, the upper support plate 1 is internally rotatably connected to a second shaft rod 15, one end of which is fixedly installed with a limit block 16, the limit block 16 is rotatably connected to the interior of the upper support plate 1, the limit block 16 is internally slidably connected to a limit rod 17, and the limit rod 17 is hinged to the top of the arc-shaped reinforcement plate 14.

[0022] It should be noted that, after the pipeline is tightened, the handle 13 is turned to make the adjusting screw 12 drive the arc-shaped reinforcement plate 14 to move in the direction of the pipeline and finally fit with the pipeline. The handle 13 is tightened to further fix the arc-shaped reinforcement plates 14 on both sides to the pipeline, thereby increasing the contact area with the pipeline and improving the tightening effect. At the same time, when the arc-shaped reinforcement plate 14 descends, the limit block 16 and the limit rod 17 will perform corresponding flipping and sliding, thereby limiting the arc-shaped reinforcement plate 14.
