Technical Field

[0001] The utility model relates to the technical field of house suspended ceilings, in particular to a bolt installation tool for suspended ceilings. Background Art

[0002] When building a suspended ceiling or installing suspended electrical appliances, it is usually necessary to use a hanging rod for hanging installation. The hanging rod includes a rod and an expansion screw. The expansion screw passes through the rod and is fixed in the installation hole. When installing the hanging rod, it is necessary to first use an impact drill to drill a suitable hole on the roof surface, insert the rear end of the expansion screw into the hole, and then hit it with a hammer to extend the entire rear part of the expansion screw into the hole. Finally, tighten the fastening nut at the front of the expansion screw with a wrench to expand the rear part of the expansion screw, and the hanging rod is connected to the roof surface. Since the expansion screw is installed at a higher position such as the roof, workers need to use ladders or scaffolding to install it. The safety factor of workers performing high-altitude operations on scaffolding or stepladders is low, and personal injuries often occur. In addition, it is very tiring for people to operate on the scaffolding. After installing one or two hanging rods, people have to come down to move the scaffolding or stepladder and then climb up to continue working, which is very inefficient.

[0003] In the prior art, in order to facilitate the tightening of the ceiling bolts, the technical solution adopted is often to fix the bolt sleeve at the end of the extension rod. The worker stands on the ground to control the extension rod and tightens the ceiling bolts through the bolt sleeve at the far end of the extension rod. However, in the prior art, the bolt sleeve on the extension rod is relatively cumbersome and difficult to disassemble, and the model of the bolt sleeve cannot be replaced conveniently and quickly, resulting in relatively low working efficiency.

[0004] Therefore, it is urgent to provide a bolt installation tool that can easily and quickly replace bolt sleeves of different models and achieve reliable fixation of the bolt sleeve on the extension rod. Utility Model Content

The rotating handle 3 and the arc-shaped clamp 4 are preferably fixedly connected, and the rotating handle 3 and the arc-shaped clamp 4 are integrally formed, and the bolt sleeve 1 can be clamped by the arc-shaped clamp 4. Anchor holes 5 are provided on the arc-shaped clamp 4 and the bolt sleeve 1. When the arc-shaped clamp 4 is aligned with the anchor hole 5 on the bolt sleeve 1, it is fixed by a detachable anchor.

[0028] Working principle, insert one end of the bolt sleeve 1 into the arc hoop 4, the bolt sleeve 1 can stretch the arc hoop 4, and then the arc hoop 4 holds the bolt sleeve 1 tightly, and at the same time align the anchor hole 5 on the bolt sleeve 1 with the anchor hole 5 on the arc hoop 4, insert the detachable anchor into the anchor hole 5, and fix the bolt sleeve 1 in the arc hoop 4, the operator makes the bayonet 2 of the bolt sleeve 1 clamp the ceiling bolt, and tighten the ceiling bolt by rotating the handle 3. When the bolt sleeve 1 needs to be replaced, the detachable anchor is removed, and the bolt sleeve 1 is pulled out of the arc hoop 4, so that the arc hoop 4 can be removed, and the bolt sleeve 1 can be quickly replaced. Moreover, when the bolt is tightened, the bolt sleeve 1 can be clamped and fixed by the arc hoop 4 and the anchor, and the handle 3 is rotated to fix the arc hoop 4, so as to fully ensure the stability of the bolt sleeve 1 during operation.

[0029] In one embodiment, Figures 1-3 As shown, the arc-shaped clamp 4 is made of stainless steel material, and the arc-shaped clamp 4 itself has a certain elasticity. When the bolt sleeve 1 is inserted into the arc-shaped clamp 4, the arc-shaped clamp 4 can be propped up. Both ends of the bolt sleeve 1 are provided with bayonet 2, and the sizes of the bayonet 2 at both ends of the bolt sleeve 1 are different. The two bayonet 2 can respectively clamp ceiling bolts of different sizes. After removing the bolt sleeve 1, it is only necessary to flip the bolt sleeve 1, insert the other end of the bolt sleeve 1 into the arc-shaped clamp 4 and fix it, and the ceiling bolts of different sizes can be tightened and fixed.

[0030] In this embodiment, a limiting protrusion 6 is provided on the outer wall of the bolt sleeve 1. The limiting protrusion 6 abuts against the arc-shaped hoop 4. The limiting protrusion 6 is located in the middle of the bolt sleeve 1, between the bayonets 2 at both ends of the bolt sleeve 1. And the anchoring holes 5 on the bolt sleeve 1 are symmetrically distributed along the axis of the bolt sleeve 1 on both sides of the limiting protrusion 6. An anchoring hole 5 is provided inside each bayonet 2 of the bolt sleeve 1. During operation, the bayonet 2 at one end of the bolt sleeve 1 is inserted into the arc-shaped hoop 4 until the limiting protrusion 6 abuts against the arc-shaped hoop 4. Furthermore, the arc-shaped hoop 4 can limit the limiting protrusion 6 and the bolt sleeve 1. At this time, the anchoring holes 5 on the bolt sleeve 1 and the anchoring holes 5 on the arc-shaped hoop 4 are in the same cross-section. When the two anchoring holes 5 are misaligned, just rotate the bolt sleeve 1 at this time to ensure that the anchoring holes 5 on the bolt sleeve 1 are aligned with the anchoring holes 5 on the arc-shaped hoop 4. Then place the detachable anchor into the anchoring hole 5 to fix the bolt sleeve 1 and the arc-shaped hoop 4.

[0031] In one embodiment, a tapered head 8 is provided at the end of the bolt sleeve 1. The tapered head 8 is smoothly connected to the main body of the bolt sleeve 1. The end of the bayonet 2 is located inside the tapered head 8. The tapered head 8 gradually contracts from the main body of the bolt sleeve 1 to the outer end. The large-diameter end of the tapered head 8 is directly butted against the main body of the bolt sleeve 1. The small end of the tapered head 8 is smaller than the diameter of the clamping hole inside the arc-shaped hoop 4. During installation, the small end of the tapered head 8 is directly inserted into the arc-shaped hoop 4. As the bolt sleeve 1 is continuously inserted, the side wall of the tapered head 8 abuts against the arc-shaped hoop 4, and the arc-shaped hoop 4 is continuously propped up by the tapered head 8 until the tapered head 8 is completely inserted into the arc-shaped hoop 4. At this time, the arc-shaped hoop 4 clamps the large-diameter end of the tapered head 8. Then, as the bolt sleeve 1 continues to move, the arc-shaped hoop 4 clamps the main body and the tapered head 8 of the bolt sleeve 1, so as to ensure that the bolt sleeve 1 can stably and quickly enter the arc-shaped hoop 4 and be clamped by the arc-shaped hoop 4.

[0032] In one embodiment, a hoop notch 7 is provided on the side wall of the arc-shaped hoop 4. The hoop notch 7 runs through along the axis of the arc-shaped hoop 4. Through the setting of the hoop notch 7, a cross-section is formed on the arc-shaped hoop 4, and two elastic sheet structures are formed on both sides of the hoop notch 7, enabling the parts (elastic sheet structures) of the arc-shaped hoop 4 on both sides of the hoop notch 7 to undergo elastic deformation within a larger range, so that the arc-shaped hoop 4 can accommodate and clamp a bolt sleeve 1 with a larger size.

[0033] In one embodiment, the arc-shaped hoop 4 includes a tightening section 9 and a cutting section 10. The tightening section 9 and the cutting section 10 are distributed on both sides of the hoop notch 7. The bolt sleeve 1 is held tightly by the tightening section 9.

[0035] In this embodiment, the rigid rod 11 has a rectangular body structure, and the connecting piece 12 has an L-shaped structure. The two main sides of the L-shaped connecting piece 12 that form a right angle are both attached to the rigid rod 11. The inner corner of the connecting piece 12 overlaps and fits with the outer corner of the rigid rod 11. Threaded holes are correspondingly arranged on the rigid rod 11 and the connecting piece 12, and the rigid rod 11 and the connecting piece 12 are connected by screws 13 to achieve reliable connection between the rigid rod 11 and the connecting piece 12. Preferably, the threaded holes are evenly arranged on the rigid rod 11 and the connecting piece 12.

[0036] In one embodiment, the detachable anchor is a bolt or a pin, ensuring that the detachable anchor can be stably inserted into the anchoring holes 5 on the arc-shaped hoop 4 and the bolt sleeve 1, so that the arc-shaped hoop 4 and the bolt sleeve 1 are reliably fixed.

[0037] In one embodiment, a sliding clamping mechanism is further included. Through the cooperation of the sliding clamping mechanism, the anchoring holes 5 on the arc-shaped hoop 4 and the bolt sleeve 1 can be aligned. The sliding clamping mechanism includes a clamping block and a clamping groove. The clamping block can be slidably clamped into the clamping groove. The clamping block is fixedly arranged on the bolt sleeve 1, and the clamping groove is arranged on the arc-shaped hoop 4. When the bolt sleeve 1 is placed into the arc-shaped hoop 4, the clamping block and the clamping groove are aligned. A clamping block insertion opening for the clamping block to insert is arranged on the clamping groove. The clamping block slides and inserts into the clamping groove until the limit protrusion 6 abuts against the arc-shaped hoop 4. At this time, the clamping block is inserted to the end of the clamping groove. Preferably, the clamping block is also limited by the clamping groove at this time to prevent the clamping block from further sliding. At this time, the anchoring holes 5 on the arc-shaped hoop 4 and the bolt sleeve 1 are strictly aligned. Just install the detachable anchor into the corresponding anchoring hole 5, and the bolt sleeve 1 and the arc-shaped hoop 4 can be quickly and reliably fixed together.

[0038] In one embodiment, a sleeve notch 14 is further provided on the bolt sleeve 1. The sleeve notch 14 penetrates through the bolt sleeve 1 and is formed on the side opposite to the anchoring hole 5 on the bolt sleeve 1.
