Description

Technical Field

[0001] The present invention relates to the technical field of fasteners, and particularly to a hoop fastener. Background Art

[0002] At present in China, most of the existing structures for installation or fastening are composed of straight-bar bolts and nuts or are formed by welding. Fasteners composed of straight-bar bolts and nuts are prone to rusting of the bolts and nuts or slipping of the threaded parts under humid and dark installation conditions, which has a great impact on installation technicians during the process of replacing fasteners.

[0003] Currently, due to the limitation of equipment update conditions that can be solved by external components in some cases and the inability to find an installation position, the installation effect is not ideal or the installation cannot be carried out, and only replacement with a new one is possible. Moreover, since most external components are welded, some components cannot be reused, and many equipment owners have to choose to purchase new equipment again, resulting in double losses of time and funds, which is extremely disadvantageous to equipment owners. In the global market currently, due to the fast product update speed and the non-uniformity of installation conditions, straight-bar bolts and nuts will separate due to vibration under different conditions, resulting in the equipment being unable to operate normally. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a hoop fastener aiming at the deficiencies of the above-mentioned prior art, which can provide a more reliable and effective fastening function.

[0005] To solve the above technical problem, the technical solution adopted by the present invention is: a hoop fastener, which includes a hoop formed by splicing a plurality of incomplete hoops; at least one of the plurality of splicing joints of the plurality of incomplete hoops is fixed by a bolt. The bolt is composed of a plurality of incomplete bolts arranged on the incomplete hoops spliced into a complete bolt, and the bolt is paired with a corresponding nut to be locked during splicing; the complete bolt has at least two bolt segments with different outer diameters. The bolt segment located inside is the first bolt segment, and the outer diameter and height of the first bolt segment are both larger than the other bolt segments, and the other bolt segments are straight-thread segments.

[0006] In the above technical solution, at least one of the plurality of splicing joints of the plurality of incomplete hoops is fixed by a lock hole and a rivet. The complete lock hole is formed by splicing a plurality of incomplete lock holes, and the rivet penetrates through to the lock hole for fixation during splicing.

[0007] In the above technical solution, the first bolt segment has no thread.

[0008] In the above technical solution, the first bolt segment is a threaded segment.

[0009] In the above technical solution, the thread depth of the threaded section gradually increases from the outside to the inside.

[0010] In the above technical solution, the first bolt section is cylindrical, frustum-shaped or arc-surface frustum-shaped.

[0011] In the above technical solution, the transition part between adjacent bolt sections is flat, frustum-shaped or arc-surface frustum-shaped.

[0012] In the above technical solution, the splicing joint between the incomplete bolts is positioned by a concave-convex structure.

[0013] In the above technical solution, the splicing joint between adjacent incomplete hoop is positioned by a concave-convex structure.

[0014] The beneficial effect of the present invention is that a complete hoop is composed of a first hoop and a second hoop, and the complete bolt jointly composed of a first bolt provided at one end of the first hoop and a second bolt provided at one end of the second hoop is tightened and locked by a nut, while the other end is locked by a rivet, realizing the locking of the object to be installed, replacing the existing locking methods of welding and straight-bar bolts, and having a more reliable and stable locking performance.

Detailed implementation mode

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] As Figures 1-12 shown, a hoop fastener includes a hoop, and the complete hoop is formed by splicing a plurality of incomplete hoops; at least one of the plurality of splicing joints of the plurality of incomplete hoops is fixed by bolts, and the complete bolt is composed of a plurality of incomplete bolts arranged on the incomplete hoops. The bolt is paired with a corresponding nut to be locked during splicing; the complete bolt has at least two bolt sections with different outer diameters. The first bolt section 11 is located inside, and the outer diameter and height of the first bolt section are both larger than the other bolt sections, and the other bolt sections are straight - thread sections. The thread thickness and depth of the bolt sections of different steps can be different or the same.

[0030] As Figure 1 shown in Embodiment 1, for the object to be hooped being a column such as a telegraph pole, the whole hoop is in a circular ring shape. The first hoop 1 and the second hoop 2 are each in a semi - circular shape and form a complete circular hoop when spliced. A convex block 9 is provided at the contact of one end of the first hoop 1 with the second hoop 2, and a corresponding groove 10 is provided at this contact of the second hoop 2. The convex block 9 and the groove 10 form a concave - convex structure to achieve alignment. At the other ends of the first hoop 1 and the second hoop 2, the first lock hole 5 and the second lock hole 6 are both provided on the hoop body. After splicing, they are stacked and aligned up and down to form a lock hole penetrated by the rivet 7, and the axial direction of this lock hole is consistent with the axial direction of the column. The first bolt 3 and the second bolt 4 are both provided with three - stage thread sections, and convex blocks 9 are provided on the splicing surface of the first bolt 3 corresponding to each stage of the thread section, and corresponding grooves 10 are provided on the splicing surface of the second bolt 4 corresponding to the convex blocks 9. The first bolt 3 and the second bolt 4 are combined in place through the concave - convex cooperation of the convex blocks 9 and the grooves 10. The structure of the nut 8 is paired with the combined bolt. Again, as Figure 1As shown, the height of the first bolt section 11 is C, the height of the second bolt section is B, the height of the third bolt section is A, and C > B > A.

[0031] As Figure 2 shown in Embodiment 2, the third bolt 13 and the fourth bolt 14 are used to replace the first locking hole and the second locking hole in Embodiment 1. After the third bolt 13 and the fourth bolt 14 are spliced, they are tightened and fixed by a nut.

[0032] As Figure 3 shown in Embodiment 3, for a main body with a U-shaped cross-section of the object to be strapped, the bolt and nut structure is used for fixing at both splicing joints.

[0033] As Figure 4 shown in Embodiment 4, for a main body with a triangular cross-section of the object to be strapped, the bolt and nut structure is used for fixing at both splicing joints.

[0034] As Figure 5 shown in Embodiment 5, for a main body with a T-shaped object to be strapped, the bolt and nut structure is used for fixing at both splicing joints.

[0035] As Figure 6 shown in Embodiment 6, for a main body with a square pipe-shaped object to be strapped, the overall shape of the hoop is a square frame. The first hoop 1, the second hoop 2, and the third hoop 15 are all in the shape of a frame and form a complete square hoop when spliced. Different from Embodiment 1, there is no concave-convex structure alignment at the splicing joints of the first hoop 1, the second hoop 2, and the third hoop 15, and only the concave-convex structure on the bolt is relied on for alignment. At the splicing joint of the third hoop 15 and the second hoop 2, the first locking hole 5 and the second locking hole 6 are respectively arranged on the outward extension part 12 of the hoop. After splicing, the first locking hole 5 and the second locking hole 6 still remain at a distance, and the rivet 7 penetrates and is riveted and locked. The first bolt 3 and the second bolt 4 are paired and both are provided with two-stage thread sections. And a convex block 9 is arranged on the corresponding first-stage thread section of the splicing surface of the first bolt 3, and a groove 10 corresponding to the convex block 9 is arranged on the splicing surface of the corresponding second bolt 4. The first bolt 3 and the second bolt 4 are combined in place through the concave-convex cooperation of the convex block 9 and the groove 10. The structure of the nut 8 is paired with the combined bolt. The third bolt 13 and the fourth bolt 14 are paired and both are provided with two-stage thread sections. And a convex block 9 is arranged on the corresponding first-stage thread section of the splicing surface of the third bolt 13, and a groove 10 corresponding to the convex block 9 is arranged on the splicing surface of the corresponding fourth bolt 14. The third bolt 13 and the fourth bolt 14 are combined in place through the concave-convex cooperation of the convex block 9 and the groove 10.

[0036] As Figure 7In the shown Embodiment 7, the hoop is composed of a first hoop 1, a second hoop 2, a third hoop 15 and a fourth hoop 16, and the adjacent hoops are respectively spliced and fixed tightly by nuts with the first bolt 3 and the second bolt 4, the third bolt 13 and the fourth bolt 14, the fifth bolt 17 and the sixth bolt 18, and the seventh bolt 19 and the eighth bolt 20.

[0037] As Figure 10 shown in the embodiment, the first bolt section 11 has no thread and only serves as a tightening function, which is applicable to the case where the outer diameter of the object to be hooped is slightly larger than the hooping diameter of the hoop, and plays a role in tightly sleeving the bolt.

[0038] As Figure 8 、 9 、11 shown in the embodiment, the first bolt section 11 is a threaded section, and the thread depth of this threaded section can be set to gradually deepen from the outside to the inside, gradually increasing the tightening force between the bolt and the nut 8.

[0039] As Figure 8 shown, the first bolt section 11 is cylindrical, and in addition, it can also be frustum-shaped or arc-shaped frustum, as Figure 9 、 10 、11 shown. And the transition part between the adjacent bolt sections is flat, frustum-shaped or arc-shaped frustum.

[0040] The working principle of the present invention: Taking Embodiment 1 as an example, after assembling the integrally formed first hoop 1 and the first bolt 3 with the integrally formed second hoop 2 and the second bolt 4, one end is tightly locked by a special nut 8, and the other end is fixed and locked by a rivet 7. When assembling, they are aligned through the concave-convex structure. When the nut 8 is tightened on the bolt, regardless of whether the first bolt section 11 has a thread, first, the first bolt section 11 will serve as a tightening member to tightly fix the first bolt 3 and the second bolt 4, and then the second bolt section is tightened by the thread; if the first bolt section 11 has a thread, then while the second bolt section is tightened by the thread, the first bolt section 11 is also tightened by the thread.

[0041] The above embodiments are only for illustration rather than limitation of the present invention. Therefore, any equivalent changes or modifications made according to the methods described in the scope of this invention patent application are included in the scope of this invention patent application.
