[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Example 1, by Figure 1 The present invention relates to a pearl cotton sleeve fastening ring structure for a steel cage, comprising a steel cage body 1, the steel cage body 1 including main steel bars 3, and a protective mechanism 2 provided on the outside of the main steel bars 3.

[0016] Specifically, by Figures 2-4 The protective mechanism 2 includes a pearl cotton protective sleeve 201 fitted around the outside of the main reinforcing bar 3. The pearl cotton protective sleeve 201 is used to protect the main reinforcing bar 3. Two fastening semicircular rings 202 are symmetrically arranged on the outside of the pearl cotton protective sleeve 201. The inner side of each of the two fastening semicircular rings 202 is provided with an arc-shaped fastening plate 204. The two arc-shaped fastening plates 204 abut against the outside of the pearl cotton protective sleeve 201. The two arc-shaped fastening plates 204 are used to clamp the pearl cotton protective sleeve 201 to the outside of the main reinforcing bar 3. The outer side of each of the two fastening semicircular rings 202 is fixedly connected to a second protrusion 2015. The outer side of each of the two second protrusions 2015 is fixedly connected to a semi-screw 2014. A threaded cylinder 203 is threaded between the two semi-screws 2014. One end of the threaded cylinder 203 is connected to the two... The second protrusion 2015 abuts against the other end of the threaded cylinder 203, which is fixedly connected to a handwheel 2013. The inner side of the threaded cylinder 203 is provided with an internal thread, and the outer sides of the two semi-screws 2014 are provided with internal threads that are compatible with the internal threads. The outer sides of the two fastening semi-circular rings 202 are fixedly connected to the first protrusion 205. The outer side of the pearl cotton protective sleeve 201 is provided with a mounting post 208. The two first protrusions 205 are movably sleeved on the outer side of the mounting post 208. The outer side of the mounting post 208 is provided with a side groove 207. The inner side of the two first protrusions 205 is fixedly connected to a side block 206. The two side blocks 206 are slidably connected to the side groove 207. Through the cooperation between the side block 206 and the side groove 207, the first protrusion 205 is limited and guided to prevent the first protrusion 205 from detaching from the mounting post 208. When the pearl cotton protective sleeve 201 is fitted on the outside of the main reinforcing bar 3, two fastening semi-circular rings 202 are placed on the outside of the pearl cotton protective sleeve 201 and moved. The two fastening semi-circular rings 202 are fixed by the cooperation between the threaded cylinder 203 and the two semi-screws 2014, thereby clamping and fixing the pearl cotton protective sleeve 201 on the outside of the main reinforcing bar 3 by the two arc-shaped fastening plates 204.

[0017] Specifically, by Figure 3As shown, a guide post 2010 is fixedly connected to the outer side of the fastening semi-circular ring 202, and a guide block 2011 is movably sleeved on the outer side of the guide post 2010. A U-shaped round rod 209 is fixedly connected to the outer side of the arc-shaped fastening plate 204. The U-shaped round rod 209 passes through the fastening semi-circular ring 202 and is movably connected to the fastening semi-circular ring 202. The guide block 2011 is fixedly sleeved on the outer middle of the U-shaped round rod 209. Through the cooperation between the U-shaped round rod 209, the guide post 2010, and the guide block 2011, the arc-shaped fastening plate 204 can move relative to the fastening semi-circular ring 202. A spring 2012 is fixedly connected between the guide block 2011 and the fastening semi-circular ring 202. The spring 2012 is sleeved on the outer side of the guide post 2010. When the arc-shaped fastening plate 204 contacts the pearl cotton protective sleeve 201 and causes the fastening semi-circular ring 202 to move, the distance between the arc-shaped fastening plate 204 and the fastening semi-circular ring 202 changes, thereby causing the spring 2012 to deform. This allows the arc-shaped fastening plate 204 to fit tightly against the pearl cotton protective sleeve 201 under the elastic force of the spring 2012, thus firmly securing the pearl cotton protective sleeve 201 to the outside of the main reinforcing bar 3.

[0018] Working principle: First, the pearl cotton protective sleeve 201 is fitted onto the outside of the main reinforcing bar 3. Then, two fastening semicircular rings 202 are placed on the outside of the pearl cotton protective sleeve 201, and the two fastening semicircular rings 202 are moved, causing the two protrusions 205 to slide along the mounting column 208. At the same time, the two arc-shaped fastening plates 204 move closer to each other. When the two arc-shaped fastening plates 204 are in contact with the pearl cotton protective sleeve 201, the two fastening semicircular rings 202 continue to move. At this time, the distance between the arc-shaped fastening plates 204 and the fastening semicircular rings 202 changes, and the guide block 2011 is driven along the guide column 2010 by the U-shaped rod 209. As the spring 2012 slides, it deforms, causing the arc-shaped fastening plate 204 to fit tightly against the pearl cotton protective sleeve 201 under the elastic force of the spring 2012, until the two protrusions 2015 fit together and the two half-screws 2014 fit together. Then, the threaded cylinder 203 is placed on the outside of the two half-screws 2014 and the handwheel 2013 is rotated clockwise, so that the threaded cylinder 203 moves on the outside of the two half-screws 2014 until it contacts the two protrusions 2015, fixing the two fastening semi-circular rings 202. Finally, the pearl cotton protective sleeve 201 is clamped and fixed on the outside of the main reinforcing bar 3, thus achieving protection for the main reinforcing bar 3.
