Description

Technical Field

[0001] This utility model relates to the field of bolt structure technology, specifically a replaceable lifting eye bolt structure. Background Technology

[0002] In industrial production and product transportation, eye bolts are often used to connect items to lifting equipment via lifting devices. Most existing eye bolts are one-piece structures, with the eye body welded or forged to the bolt. Although they have high strength, once the eye or threads are damaged, they cannot be disassembled and replaced individually, and the entire bolt must be scrapped.

[0003] Based on this, the present invention designs a replaceable lifting eye bolt structure to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a replaceable eye bolt structure to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a replaceable lifting eye bolt structure, comprising: a lifting eye and a bolt; two integrally formed arms are symmetrically arranged at one end of the lifting eye, and a pin is fixedly connected to one end of the two arms facing each other; a locking pin is provided at one end of the pin, and a small shaft connecting section is fixedly connected between the pin and the locking pin;

[0006] Two limiting rings are symmetrically fixed to the outer wall of the bolt. A front retaining seat and a rear retaining seat are detachably connected between the two limiting rings. After the front retaining seat and the rear retaining seat are assembled, they form a plurality of interconnected bayonet structures for limiting the insert, retaining post and connecting post. The insert, retaining post and small shaft connecting section can be rotatably installed in the corresponding bayonet.

[0007] Preferably, the front and rear card seats are respectively provided with mutually cooperating limiting grooves at their joint ends, and the bolt rod between the two limiting rings is embedded in the limiting groove.

[0008] Preferably, the front card holder assembly end is provided with a plurality of screw holes, and the rear card holder assembly end is provided with a corresponding threaded groove that mates with the screw holes.

[0009] Preferably, one end of each of the screws is threaded into the threaded groove to achieve the assembly and disassembly of the front and rear retainers.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the lifting ring is locked and limited by the merging front and rear clamps, and if either the lifting ring or the bolt is damaged, it can be disassembled and replaced separately without being scrapped as a whole. During use, the lifting ring can rotate relative to the front and rear clamps, and the front and rear clamps can rotate relative to the bolt, which improves the applicability of lifting operations.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a replaceable lifting eye bolt structure, including: a lifting eye 1 and a bolt 2; one end of the lifting eye 1 is symmetrically provided with two integrally formed arms 3, one end of the two arms 3 is fixedly connected with a pin 7 facing each other, one end of the pin 7 is provided with a locking pin 8, and a small shaft connecting section is fixedly connected between the pin 7 and the locking pin 8.

[0020] Two limiting rings 4 are symmetrically fixed on the outer wall of bolt 2. A front retaining seat 5 and a rear retaining seat 6 are detachably connected between the two limiting rings 4. After the front retaining seat 5 and the rear retaining seat 6 are assembled, they form a multi-connected bayonet structure for limiting the insert 7, retaining post 8 and connecting post. The insert 7, retaining post 8 and small shaft connecting section can be rotatably installed in the corresponding bayonet.

[0021] The lifting ring 1 is connected to the front bracket 5 and the rear bracket 6 via two booms 3 and a plug 7. The plug 7 is connected to a locking pin 8, and a small shaft connecting section serves as the pivot. The plug 7 and the locking pin 8 form a multi-point support, which, combined with the locking slot limit, makes it difficult for the lifting ring 1 to come out when rotating. The bolt 2 is equipped with two limiting rings 4. The front bracket 5 and the rear bracket 6 can be disassembled and assembled. The front bracket 5 and the rear bracket 6 form multiple locking slots, which respectively accommodate the plug 7, the locking pin 8 and the small shaft connecting section, enabling the lifting ring 1 to be rotatably installed. It has a certain tensile and torsional resistance, which meets the requirements of multi-directional lifting operations. The detachability of the front bracket 5 and the rear bracket 6 allows the lifting ring 1 or the bolt 2 to be disassembled separately.

[0022] In a further preferred embodiment, the front retainer 5 and the rear retainer 6 are respectively provided with mutually cooperating limiting grooves at their joint ends, and the bolt 2 rod between the two limiting rings 4 is embedded in the limiting groove;

[0023] The front and rear card holders 5 and 6 are fitted with matching limiting grooves at their joint. These grooves are used to position and limit the bolt 2 rod between the two limiting rings 4, forming an embedded connection. This enhances the reliability of the card holder fixation and prevents the front and rear card holders 6 from shifting due to vibration or external force during use.

[0024] More preferably, the front card holder 5 has a plurality of screw holes 10 at the splicing end, and the rear card holder 6 has a corresponding threaded groove 9 that mates with the screw holes 10 at the splicing end;

[0025] The front bracket 5 is provided with screw holes 10, and the rear bracket 6 is provided with threaded grooves 9 that cooperate with it. The front and rear brackets 6 are fixed together by screws 10, which facilitates repeated assembly.

[0026] More preferably, one end of each of the multiple screws 10 is threaded into the threaded groove 9 to achieve the disassembly and assembly of the front retainer 5 and the rear retainer 6;

[0027] Multiple screws 10 are threaded at one end into the threaded groove 9 of the rear retainer 6 to fasten the front retainer 5 and the rear retainer 6 together. Multiple screws 10 provide uniform clamping force to avoid displacement caused by unilateral force. Moreover, multi-point connection is more shock-resistant and more reliable than single-point connection.

[0028] One specific application of this embodiment is as follows: During assembly, one of the front bracket 5 or the rear bracket 6 is first attached to the rod between the two limiting rings 4 of the bolt 2 through the limiting groove. Then, the inserts 7, the locking pins 8, and the small shaft connecting sections of the two arms 3 of the lifting ring 1 are respectively installed in the corresponding slots of the front bracket 5 or the rear bracket 6. Then, one end of the screw 10 can be screwed into the threaded groove 9 of the rear bracket 6 through the screw 10 hole of the front bracket 5. After tightening them one by one, the assembly is completed. The disassembly and replacement steps are to remove all the screws 10, loosen the connection between the front bracket 5 and the rear bracket 6, remove the bracket, and take out the lifting ring 1 component. If a new lifting ring 1 or bolt 2 needs to be replaced, it can be reassembled according to the installation steps.

[0029] During use, the lifting ring 1 can rotate relative to the front bracket 5 and the rear bracket 6, and the front bracket 5 and the rear bracket 6 can rotate relative to the bolt 2.
