Description

Technical Field

[0001] The utility model specifically relates to an anti-dropping U-shaped bolt. Background Art

[0002] U-bolts, also known as riding bolts, are non-standard parts. They are named after their U-shaped shape. They have threads at both ends that can be combined with nuts. They are mainly used to fix tubular objects such as water pipes or sheet objects such as car leaf springs.

[0003] At present, when the U-bolt is used to fix the tubular object, the outer wall of the tubular object will rub against the inner wall of the U-bolt, resulting in wear inside the U-bolt, thereby causing shaking, making the fixation unstable. Utility Model Content

[0004] The utility model aims to provide an anti-dropping U-shaped bolt to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-slip U-shaped bolt, comprising a U-shaped bolt body, two insertion ends are arranged on one side of the open end of the U-shaped bolt body, the two insertion ends are used to fix the U-shaped bolt body to a mounting surface, a limiting shell for fixing a pipeline is arranged on the U-shaped bolt body, and a lubrication unit is arranged on the side of the limiting shell facing the pipeline.

[0006] Preferably, the side of the limiting shell away from the insertion end is in an arc shape adapted to the U-shaped bolt body, and a limiting area for fixing the pipeline is formed between the limiting shell and the U-shaped bolt body.

[0007] Preferably, the insertion end head is provided with a thread downward, and a positioning nut is sleeved on the outer side of the thread.

[0008] Preferably, the limiting shell is rectangular on the side facing the insertion end, and the positioning nut abuts against the upper surface of the limiting shell.

[0009] Preferably, the lubrication unit comprises a groove formed on an arc-shaped side of the limiting housing, and two connecting rods and rollers are arranged in the groove.

[0010] Preferably, the two connecting rods are respectively arranged on both sides of the groove, and the roller is arranged between the two connecting rods.

[0011] Preferably, a through hole for inserting the insertion end is formed on the upper surface of the limiting shell.

[0012] The technical effects and advantages of the utility model are as follows: the anti-slip U-bolt places the tubular object to be fixed in the U-bolt body, and then aligns the through hole opened on the upper surface of the limit shell with the insertion end, and moves the limit shell through the through hole, so that the arc-shaped side of the limit shell abuts against the outside of the tubular object, and then screws the positioning nut so that the two positioning nuts fix the limit shell, thereby completing the fixation of the tubular object, and when installing the limit shell, the roller rolls along the outer wall of the tubular object, which can reduce the friction of the tubular object on the inner wall of the limit shell when installing, thereby improving the service life and the timeliness of the later fixation of the tubular object.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] In order to improve the timeliness of the later fixation of the tubular object, refer to Figure 1 , Figure 2 and Figure 3 As shown, it includes a U-shaped bolt body 1, and two insertion ends 2 are arranged on one side of the open end of the U-shaped bolt body 1. The two insertion ends 2 are used to fix the U-shaped bolt body 1 to the installation surface. A limiting shell 3 for fixing the pipeline is arranged on the U-shaped bolt body 1, and a lubrication unit is arranged on the limiting shell 3 facing the pipeline. The tubular object to be fixed is placed in the U-shaped bolt body 1, and then the through hole 9 opened on the upper surface of the limiting shell 3 is aligned with the insertion end 2, and the limiting shell 3 is moved through the through hole 9 so that the arc-shaped side of the limiting shell 3 abuts against the outer side of the tubular object, and then the positioning nut 5 is screwed so that the two positioning nuts 5 fix the limiting shell 3, thereby completing the fixation of the tubular object, and when the limiting shell 3 is installed, the roller 8 rolls along the outer wall of the tubular object, which can reduce the friction of the inner wall of the limiting shell 3 when the tubular object is installed, thereby improving the service life.

[0020] In order to improve the service life of the limit housing 3, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the side of the limit housing 3 away from the insertion end 2 is in an arc shape that is compatible with the U-shaped bolt body 1. The arc shape is compatible with the outer side of the tubular object so as to better fit with the tubular object, thereby better fixing the tubular object. A limit area for fixing the pipeline is formed between the limit housing 3 and the U-shaped bolt body 1, and the tubular object is fixed by the limit area to achieve positioning. The head of the insertion end 2 is provided with a thread 4 downward, and a positioning nut 5 is sleeved on the outer side of the thread 4. The thread 4 nut is rotated by the thread 4 to fix the limit housing 3, so that the limit housing 3 can firmly fix the tubular object and improve stability. The limit housing 3 is rectangular on the side facing the insertion end 2, and the positioning nut 5 abuts against the upper surface of the limit housing 3, so as to rotate the positioning nut 5 to fix the limit housing 3.

[0021] Furthermore, the lubrication unit includes a groove 6 provided on the arc-shaped side of the limit housing 3, and two connecting rods 7 and a roller 8 are provided in the groove 6. When the limit housing 3 is moved to position the tubular object, the roller 8 rotates between the two connecting rods 7 and rolls along the outer side of the tubular object, thereby reducing the friction of the outer wall of the tubular object on the arc-shaped side of the limit housing 3, avoiding loss, and improving the service life of the limit housing 3. The two connecting rods 7 are respectively provided on both sides of the groove 6, and the roller 8 is provided between the two connecting rods 7. A through hole 9 is provided on the upper surface of the limit housing 3 for the insertion end 2 to be inserted, and the installation and removal of the limit housing 3 are facilitated through the through hole 9.

[0022] When in use, first place the tubular object to be fixed in the U-bolt body 1, then align the through hole 9 opened on the upper surface of the limit shell 3 with the insertion end 2, and move the limit shell 3 through the through hole 9, so that the arc-shaped side of the limit shell 3 abuts against the outside of the tubular object, and then screw the positioning nut 5 so that the two positioning nuts 5 fix the limit shell 3, thereby completing the fixation of the tubular object, and when installing the limit shell 3, the roller 8 rolls along the outer wall of the tubular object to make the tubular object smoother when being installed.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
