[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] See also Figure 1-Figure 4 In an embodiment of the utility model, a bolt sleeve for fixing a steel bar to prevent loosening comprises:

[0027] The connecting pipe 1 is provided with four connecting pipes 1, which are cross-shaped and vertically connected to each other. The connecting pipes 1 are each provided with an internal thread 13, and the internal thread 13 is matched with the thread at the end of the threaded steel bar 2. When in use, the sleeve is placed in the required position, and the four connecting pipes 1 vertically connected to each other can connect multiple threaded steel bars 2 at the same time, which has wide applicability and is easy to use.

[0028] The connecting ends of the connecting pipes 1 are each provided with a fastening assembly for fixing the threaded steel bars 2. The fastening assembly comprises an upper fixing block 5 and a lower fixing block 8. The upper fixing block 5 is fixedly connected to two hook heads 6, and the lower fixing block 8 is fixedly connected to two buckles 7 corresponding to the hook heads 6. The upper fixing block 5 and the lower fixing block 8 are each provided with a fastening groove 14. When in use, when the threaded steel bars 2 are threadedly connected in the connecting pipe 1, the upper fixing block 5 and the lower fixing block 8 are sleeved on the threaded steel bars 2, and then the upper fixing block 5 and the lower fixing block 8 are connected together by the buckles 7, and the threaded steel bars 2 are fixed by the fastening grooves 14 in the upper fixing block 5 and the lower fixing block 8 to prevent the threaded steel bars 2 from rotating.

[0029] The upper fixing block 5 and the lower fixing block 8 are both provided with fixing components for fixing the connecting pipe 1 and the threaded steel bar 2. The fixing components include a slot 3 and a positioning block 4. The positioning block 4 is fixedly connected to both sides of the connecting end of the connecting pipe 1. The positioning block 4 is provided with a slot 3. The upper fixing block 5 and the lower fixing block 8 are both fixedly connected with a connecting block 11. The connecting block 11 is fixedly connected with a blocking block 12. The blocking block 12 is provided with an inner groove 10 on the side away from the connecting block 11. A stopper 15 is provided at the end of the inner groove 10. A spring 9 is fixedly connected between the stopper 15 and the inner groove 10. When the fastening component fastens the threaded steel bar 2, the stopper 15 on the upper fixing block 5 and the lower fixing block 8 is simultaneously stuck in the slot 3 on the positioning block 4, so that the connecting pipe 1 and the threaded steel bar 2 are fixed and the connecting pipe 1 and the threaded steel bar 2 cannot rotate, thereby realizing that the threaded steel bar 2 can be firmly connected in the connecting pipe 1.

[0030] The side of the stopper 15 close to the slot 3 is all inclined. When in use, the stopper 15 with the inclined surface can be more conveniently and easily stuck in the slot 3, so that the connecting pipe 1 and the threaded steel bar 2 are fixed, and it is also convenient to operate when disassembling.

[0031] The connecting pipes 1 are all made of alloy steel. When in use, the connecting pipes 1 made of alloy steel have the effects of high strength, wear resistance and corrosion resistance.

[0032] The upper fixing block 5 and the lower fixing block 8 are rotatably connected away from the side of the buckle 7. When in use, the rotatable connection between the upper fixing block 5 and the lower fixing block 8 can make it easier for the fastening assembly to cover the threaded steel bar 2, so that the threaded steel bar 2 is fixed and cannot rotate, which is easy to use.

[0033] The fastening groove 14 is fastened to the threads on the threaded steel bar 2. When the upper fixing block 5 and the lower fixing block 8 fasten the threaded steel bar 2, the fastening groove 14 in the upper fixing block 5 and the lower fixing block 8 will be fastened to the raised patterns on the threaded steel bar 2, fixing the threaded steel bar 2 and preventing it from rotating, thereby better fastening the threaded steel bar 2 and preventing the threaded steel bar 2 from loosening.

[0034] Example 2

[0035] The difference from Example 1 is that the upper fixing block 5 and the lower fixing block 8 are both made of cast iron. When in use, the upper fixing block 5 and the lower fixing block 8 made of cast iron have the effects of high strength, high hardness and corrosion resistance.

[0036] The working principle of the utility model is as follows: when in use, the sleeve is placed in the designated position, and then the pre-prepared threaded steel bars 2 are respectively threadedly connected in each connecting pipe 1, and the connecting pipe 1 is provided with four, which are respectively vertically connected to each other. After the threaded steel bars 2 are threadedly connected in the connecting pipe 1, the upper fixing block 5 and the lower fixing block 8 are respectively sleeved and clamped with the threaded steel bars 2, so that the stoppers 15 on the upper fixing block 5 and the lower fixing block 8 are respectively clamped in the clamping grooves 3 on the positioning block 4, and the positioning block 4 is fixedly connected to the connecting pipe 1, so that the threaded steel bars 2 and the connecting pipe 1 cannot rotate. After the upper fixing block 5 and the lower fixing block 8 clamp the threaded steel bar 2, the upper fixing block 5 and the lower fixing block 8 are connected together through the buckle 7 and the hook head 6 buckle 7, so that the threaded steel bar 2 is fixedly connected to the connecting pipe 1, which effectively prevents loosening after long-term use. When disassembly is required, first open the buckle 7, then press the stopper 15 to loosen the clamping block 12 from the clamping groove 3, then loosen the upper fixing block 5 and the lower fixing block 8, and finally loosen the threaded steel bar 2 from the connecting pipe 1, and the disassembly is completed. It is highly practical and easy to use.
