[0001] The utility model relates to the technical field of anchor bolts, in particular to a high-strength heat-insulating and anti-falling anti-seismic anchor bolt. Background Technique

[0002] An anchor bolt refers to the general term for all post-anchoring components, with a wide range. It is divided into metal anchor bolts and non-metal anchor bolts according to different raw materials. It is divided into expansion anchor bolts, under-reamed anchor bolts, bonded anchor bolts, concrete screws, nail guns, concrete nails, etc. according to different anchoring mechanisms.

[0003] During the use of the current expansion anchor bolt, it mainly squeezes the expansion sleeve by the movement of the screw rod, so that the expansion sleeve expands and deforms to closely fit the contact surface to realize the fastening of the anchor bolt. However, in actual use, some anchor bolts are installed downward, and a certain weight of object is suspended on the anchor bolt after installation, which causes a large suspension force on the expansion sleeve after it contacts the contact surface, and it is easy to cause the anchor bolt to fall downward, resulting in unstable suspension of the object.

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Refer to Figures 1-3, A high-strength heat-insulating and anti-falling anti-seismic anchor bolt, which includes an expansion sleeve 1 and a screw rod 2. The expansion sleeve 1 is sleeved on the side wall of the screw rod 2, and one end of the screw rod 2 close to the expansion sleeve 1 is a conical body.

[0021] A nut 4 is threadedly connected to the side wall of the screw rod 2 away from the expansion sleeve 1. A gasket 3 is sleeved on the side wall of the screw rod 2 between the expansion sleeve 1 and the nut 4. A plurality of through grooves 5 are opened on the side wall of the expansion sleeve 1 away from the nut 4.

[0022] Both the expansion sleeve 1 and the screw rod 2 are made of high-carbon steel, and heat-insulating layers are coated on the side walls of the expansion sleeve 1 and the screw rod 2 to increase the self-strength of the anchor bolt and the heat-insulating property of the anchor bolt.

[0023] An anti-falling mechanism, which includes a fixing ring 6 fixedly connected to the side wall of the screw rod 2. The fixing ring 6 is located inside the expansion sleeve 1. A plurality of grooves 10 are opened on the side wall of the expansion sleeve 1. A sliding plate 11 is slidably connected to the inner wall of the groove 10. A plurality of nails 12 are fixedly connected to the side wall of the sliding plate 11 away from the groove 10. A first rod 13 is fixedly connected to the side wall of the sliding plate 11 away from the nails 12. The side wall of the first rod 13 penetrates through the side wall of the expansion sleeve 1 and extends into its interior. The side wall of the fixing ring 6 is rotatably connected to the side wall of its corresponding first rod 13 through a second rod 14.

[0024] Further, when the anchor bolt is inserted into the installation hole at the top of the wall, at this time, when the nut 4 is rotated, the screw rod 2 will move outward from the installation hole. At this time, the conical end of the screw rod 2 will squeeze one end of the expansion sleeve 1, so that the expansion sleeve 1 expands and deforms to closely fit with the inner wall of the installation hole, realizing the fastening of the anchor bolt. During this process, the fixing ring 6 will move outward from the installation hole synchronously. The fixing ring 6 will drive the sliding plate 11 to move towards the installation hole through the second rod 14 and the first rod 13, so that a plurality of nails 12 are inserted into the installation hole, further stabilizing the installation position of the anchor bolt and preventing the anchor bolt from falling. It avoids the situation in the prior art that some anchor bolts are installed downward, and a certain weight of object is hung on the anchor bolt after installation, which results in a large hanging force on the contact surface after the expansion sleeve contacts the contact surface, and it is easy to cause the anchor bolt to fall downward, resulting in unstable hanging of the object.

[0025] It also includes a seismic mechanism, which includes a plurality of sliding grooves 7 opened on the side wall of the fixing ring 6. A buffer plate 8 is slidably connected to the inner wall of the sliding groove 7. The side wall of the buffer plate 8 is elastically connected to the inner wall of the sliding groove 7 through a plurality of shock-absorbing springs 9. The side wall of the buffer plate 8 is attached to the inner wall of the expansion sleeve 1.

[0026] Further, when the anchor bolt encounters vibration during use, at this time, the buffer plate 8 and the shock-absorbing springs 9 will first absorb the vibration force, thereby reducing the vibration force received by the subsequent anchor bolt, playing a shock-absorbing effect on the anchor bolt, and further increasing its installation firmness.

[0027] During the use of this anchor bolt, the anchor bolt is inserted into the installation hole at the top of the wall. At this time, when the nut 4 is rotated, the screw rod 2 will move out of the installation hole. One end of the screw rod 2 with a conical shape will squeeze one end of the expansion sleeve 1, causing the expansion sleeve 1 to expand and deform to closely fit the inner wall of the installation hole, realizing the fastening of the anchor bolt. During this process, the fixing ring 6 will move out of the installation hole synchronously. The fixing ring 6 will drive the sliding plate 11 to move towards the installation hole through the second rod 14 and the first rod 13, so that multiple nails 12 are inserted into the installation hole, further stabilizing the installation position of the anchor bolt and preventing the anchor bolt from falling;

[0028] When the anchor bolt encounters vibration during use, at this time, the buffer plate 8 and the shock-absorbing spring 9 will first absorb the vibration force, thereby reducing the vibration force received by the subsequent anchor bolt, achieving the shock-absorbing effect on the anchor bolt and further increasing its installation firmness;

[0029] Moreover, both the expansion sleeve 1 and the screw rod 2 are made of high-carbon steel, and heat-insulating layers are coated on the side walls of the expansion sleeve 1 and the screw rod 2 to increase the self-strength of this anchor bolt and its heat-insulating property.

[0030] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
