Description

Technical Field

[0001] The utility model relates to a lifting ring expansion bolt with an adjustable lifting ring head. Background Art

[0002] The eyebolt is an expansion bolt with an eyebolt, which is fixed on the bolt. After installation, the eyebolt is used to allow ropes to pass through or connect to lift objects, or to allow tubular bodies to pass through the eyebolt and use the eyebolt to support the tubular body. However, this eyebolt has obvious limitations in actual use. Since the eyebolt is fixed on the bolt, the position of the eyebolt is fixed when the expansion bolt is fixed. When the connection distance or installation distance deviates from the eyebolt, the user needs to use other auxiliary connectors to make up for the connection, which has limitations and inconveniences in use.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] The utility model aims to overcome the above problems and provides a lifting ring expansion bolt with an adjustable lifting ring head. The lifting ring of the lifting ring expansion bolt can be adjusted.

[0005] To achieve the above-mentioned purpose, the utility model provides a lifting eye expansion bolt with an adjustable lifting eye head, which includes a sleeve, a bolt and a lifting eye screw. The side wall of the sleeve is provided with a groove body extending upward along the bottom, the bolt is inserted into the sleeve, the bottom end of the bolt extends out of the bottom of the sleeve and is provided with an expansion head, the top of the sleeve is provided with a nut threadedly connected to the bolt, a threaded hole is opened in the middle of the bolt, and the lifting eye screw consists of a ring body and a stud, and the stud is connected to the threaded hole.

[0006] In one or more embodiments, the ring body is welded and fixed to the top of the stud, and the diameter of the ring body is 15MM-35MM.

[0007] In one or more embodiments, the depth of the threaded hole is at least one third of the length of the bolt, and the length of the stud is greater than the depth of the threaded hole.

[0008] In one or more embodiments, the circular diameter of the threaded hole is one third to one half of the circular diameter of the bolt.

[0009] In one or more embodiments, there are multiple grooves, and the multiple grooves are evenly distributed along the circumference of the side wall of the sleeve.

[0010] In one or more embodiments, a gasket is disposed between the nut and the sleeve.

[0011] In one or more embodiments, the sleeve, bolt and eye screw are made of stainless steel.

[0012] Compared with the background technology, the utility model has the following effects: the lifting ring of the lifting ring expansion bolt can be adjusted by rotating to adjust the extension distance of the lifting ring, and after the expansion bolt is fixed, the lifting ring can be rotated to meet the installation requirements, thereby solving the limitations and inconveniences of the use of lifting ring expansion bolts currently on the market.

[0015] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0016] Please see attached Figure 1-2 The present application provides a lifting eye expansion bolt with an adjustable lifting eye head, which includes a sleeve 1, a bolt 2 and a lifting eye screw. The sleeve 1, the bolt 2 and the lifting eye screw are made of stainless steel. The side wall of the sleeve 1 is provided with a groove body 3 extending upward along the bottom. The bolt 2 is inserted into the sleeve 1. The bottom end of the bolt 2 extends out of the bottom of the sleeve 1 and is provided with an expansion head 21. The top of the sleeve 1 is provided with a nut 4 threaded with the bolt. A threaded hole 5 is opened in the middle of the bolt 2. The lifting eye screw is composed of a ring body 6 and a stud 7, and the stud is connected to the threaded hole. During installation, the sleeve is buried in the opened hole, and the nut is turned with a wrench to move the bolt outward. During the movement, the expansion head 21 squeezes and stretches the bottom of the sleeve, thereby locking the sleeve and the hole. By turning the lifting eye screw, the lifting eye screw can be adjusted outward or inward to meet the installation requirements.

[0017] The ring body 6 is welded and fixed to the top of the stud 7, and the diameter of the ring body is 15MM-35MM, preferably 15MM, 20MM, 25MM, 28MM, 30MM and other sizes. The diameter of the ring body is proportional to the diameter of the sleeve.

[0018] The depth of the threaded hole 5 is at least one third of the length of the bolt 2, and the length of the stud 7 is greater than the depth of the threaded hole, ensuring that the eye screw has a certain length adjustment range and that the stud and the threaded hole have a certain connection area, thereby ensuring the structural stability of the eye screw.

[0019] The diameter of the threaded hole 5 is one third to one half of the diameter of the bolt 2, so as to avoid the threaded hole being too large and causing the bolt structure to be unstable.

[0020] There are multiple grooves 3, which are evenly distributed along the circumference of the side wall of the sleeve, so that the expansion head can better expand the bottom of the cylinder.

[0021] A gasket 8 is provided between the nut 4 and the sleeve 1, and the gasket can prevent the nut from directly contacting the sleeve, thereby indirectly enhancing the stress strength at the top of the sleeve.

[0022] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
