Description

Technical Field

[0001] The utility model relates to the technical field of U-shaped bolts, in particular to an extendable U-shaped bolt. Background Art

[0002] A U-bolt, also known as a riding bolt, is a non-standard part. It is named for its U-shaped shape. It has threads at both ends that can be combined with nuts. It is mainly used to fix tubular objects such as water pipes or sheet objects such as leaf springs of cars. Since it fixes objects in a way that is like a person riding on a horse, it is called a riding bolt. Announcement No. CN219262917U discloses a U-bolt comprising a U-shaped screw and a nut. A reinforcement sleeve is provided on the nut. A reinforcement stud is provided on the side of the reinforcement sleeve facing the U-shaped screw. A reinforcement nut is provided on the reinforcement stud. The length direction of the reinforcement stud is the same as the length direction of the cylindrical section of the U-shaped screw. A pressure plate is provided on the U-shaped screw, and a first through hole for the reinforcement stud to pass through is provided on the pressure plate. The reinforcing sleeve provided by the utility model can be sleeved on the nut after the nut is tightened, and is fixed to the pressure plate by the reinforcing stud, so as to fix the nut and make the nut unable to move, thereby preventing the nut from loosening due to frequent vibration, thereby affecting the fixing effect; the rubber gasket provided makes the nut and the reinforcing sleeve tighter, and the fixing effect is better. Although the product has achieved the good fixing effect of preventing the nut from loosening during use, the product does not have the function of adjusting the length of the U-bolt, so that it may encounter space limitations or fail to reach the ideal position during installation. This may require finding alternative solutions or on-site adjustments, which increases the complexity and time of installation, and has poor practicality and needs to be improved.

The limit block 1 3 is slidably connected with the mounting hole 11, the limit block 13 is slidably connected with the limit hole 10, and the limit block 13 allows the extended bolt body 4 and the extended bolt body 2 6 to be fixed and clamped after the length is adjusted, the second bolt body 2 is slidably connected with the slide groove three 14, so that the first bolt body 1 and the second bolt body 2 can be adjusted to change the opening size of the U-bolt, so as to be suitable for products of different specifications, and the fixed threaded rod 15 is threadedly connected with the threaded hole 18, and the first bolt body 1 and the second bolt body 2 are fixed and clamped by the fixed threaded rod 15.

[0028] Embodiment 2

[0029] See also Figure 7-8The surfaces of the first bolt body 1 and the second bolt body 2 are fixedly installed with anti-skid pads 19, which can increase friction and prevent the bolts from loosening when subjected to force or vibration. The internal thread connection of the positioning steel plate 9 is connected with a fixed threaded rod 20, so that the clamping plate 21 can be installed. One end of the fixed threaded rod 20 is rotatably connected with the clamping plate 21, which can fix the pipe fitting more stably. The surface of the clamping plate 21 is fixedly installed with a sliding rod 22 to limit the clamping plate 21. The internal rotation connection of the nut 8 is connected with a fixed threaded rod 3 23. The surface of the threaded column 7 is provided with a threaded hole 24. The contact area between the U-bolt and the pipeline is increased by the clamping plate 21 and the anti-skid pad 19, so that the force is more stable, thereby improving the stability of the U-bolt when in use. The fixed threaded rod 3 23 is threadedly connected with the threaded hole 24. The fixed threaded rod 3 23 can effectively prevent the nut 8 from loosening, thereby avoiding the loosening between the U-bolt and the pipeline.

[0030] Working principle: When using the U-bolt, first, the pipe to be tightened is pressed against the contact surface of the first bolt body 1 and the second bolt body 2, and then the clamping steel plate 9 is inserted into the threaded column 7, and the clamping plate 21 is locked by rotating the nut 8, and then the fixed threaded rod 20 is rotated to make the clamping plate 21 close to the surface of the pipe. At this time, the sliding rod 22 will slide inside the clamping steel plate 9, so that the clamping plate 21 is more stable when moving, and the surface of the pipe will fit the surface of the anti-slip pad 19 of the first bolt body 1 and the second bolt body 2, and then the fixed threaded rod 3 23 is rotated to screw into the threaded hole 24 opened in the threaded column 7, thereby increasing the contact area between the U-bolt and the pipeline, making the force more stable, and at the same time, it can effectively prevent the nut 8 from loosening, thereby avoiding the loosening between the U-bolt and the pipeline, and improving the stability between the U-bolt and the pipeline. When the length of the U-bolt needs to be adjusted during installation, first press the limit block 13 downward, and the spring 12 will be compressed at the same time. Then, grab the extended bolt body and pull it. At this time, the limit block 13 will slide inside the bolt body. When it slides to the same position as the limit hole 10 opened in the bolt body, the limit block 13 will automatically pop out under the action of the spring 12, thereby completing the adjustment of the length of the U-bolt, so that the U-bolt can adapt to different installation depths or distances. When the opening size of the U-bolt needs to be adjusted during installation, first rotate the turntable 16 to unscrew it from the threaded hole 18 opened in the second bolt body 2, and then pull the second bolt body 2 to move, thereby realizing the adjustment of the opening size of the U-bolt, and then making it suitable for products of different specifications, thereby improving the application range of the U-bolt and reducing the need for U-bolts of multiple specifications.
