The threads at both ends of the screw rod 6 have opposite rotation directions, and the two ends of the screw rod 6 are respectively threadedly installed with a nut 7, and the outer circumference of the arc plate 4 is respectively connected to one end of the two connecting rods 8 through a hinge shaft, and the other ends of the two connecting rods 8 on the same arc plate 4 are sequentially connected to the outer circumference of the two nuts 7 on the same screw rod 6 through a hinge shaft. The fastening device in the utility model has a simple structure and an ingenious design. The screw 6 drives the nut 7 to move, and then drives the arc plate 4 to move through the connecting rod 8, so that the arc plate 4 is tightly against the outer periphery of the building structure. It has good stability, high practicality and a relatively simple structure, can meet actual needs, and is suitable for promotion. When using the utility model, the left anti-collision ring 101 and the right anti-collision ring 102, the left clamping ring 201 and the right clamping ring 202 are mounted on the outer periphery of the building structure and fixedly connected, and then the screw rod 6 is turned in the positive direction, and the rotation of the screw rod 6 drives the corresponding two screw nuts 7 to move in the direction of approaching each other, and the corresponding connecting rod 8 and the end hingedly connected to the screw nut 7 move in the direction of approaching each other. Since the length of the connecting rod 8 remains unchanged, the connecting rod 8 rotates around the corresponding hinge axis, and several arc plates 4 move in the direction of approaching the building structure until the inner peripheries of the arc plates 4 are tightly abutted against the outer periphery of the building structure respectively, thereby clamping the building structure. When an object hits the anti-collision mechanism 1, several springs 3 are compressed, and the spring 3 buffers the external impact force to protect the building structure.

[0017] Specifically, as shown in the figure, the edges connecting the left anti-collision ring 101 and the right anti-collision ring 102 described in this embodiment are cross-engaged, and two first through holes 20 are respectively provided on the left anti-collision ring 101 and the right anti-collision ring 102, and the first through holes 20 penetrate the corresponding cross-engaging parts, and the first positioning bolts 21 are respectively slidably installed in the first through holes 20, and the two ends of the first positioning bolts 21 are respectively threadedly fitted with the first nuts 22, and the first nuts 22 are respectively abutted and contacted with the upper and lower sides of the left anti-collision ring 101 and the right anti-collision ring 102; the edges connecting the left clamping ring 201 and the right clamping ring 202 are also cross-engaged, and two second through holes 23 are respectively provided on the left clamping ring 201 and the right clamping ring 202, and the second through holes 23 penetrate the corresponding cross-engaging parts, and the second positioning bolts 24 are respectively slidably installed in the second through holes 23, and the two ends of the second positioning bolts 24 are respectively threadedly fitted with the second nuts 25, and the second nuts 25 are respectively abutted and contacted with the upper and lower sides of the left clamping ring 201 and the right clamping ring 202. When the anti-collision device is installed on the building structure, first align the stepped edges of the left anti-collision ring 101 and the right anti-collision ring 102, and the left clamping ring 201 and the right clamping ring 202 respectively, and then install the first positioning bolt 21 and the second positioning bolt 24 in the first through hole 20 and the second through hole 23 respectively, and make both ends of the first positioning bolt 21 and the second positioning bolt 24 extend, and install the first nut 22 and the second nut 25 on the extended ends of the first positioning bolt 21 and the second positioning bolt 24 respectively by threaded cooperation, so as to connect the left anti-collision ring 101 and the right anti-collision ring 102, and the left clamping ring 201 and the right clamping ring 202.

[0018] Specifically, as shown in the figure, the outer peripheries of the left clamping ring 201 and the right clamping ring 202 described in this embodiment are respectively provided with arc-shaped first T-shaped grooves 30, and the arc-shaped first T-shaped sliders 31 are respectively slidably installed in the first T-shaped grooves 30. The two first T-shaped grooves 30 form an annular T-shaped groove mechanism, and a plurality of springs 3 are fixedly installed on the outer periphery of the first T-shaped slider 31. Two rows of springs 3 are fixedly installed on the outer periphery of each first T-shaped slider 31, and three springs 3 are evenly arranged in each row. The outer ends of the springs 3 are respectively fixedly connected to the inner walls of the corresponding left anti-collision ring 101 or the right anti-collision ring 102.

When the left anti-collision ring 101 and the right anti-collision ring 102 are subjected to force, the first T-shaped slider 31 will slide in the first T-shaped slide groove 30, further reducing the impact force exerted on the left anti-collision ring 101 and the right anti-collision ring 102, thereby protecting the building structure.

[0019] Further, as shown in the figure, one end of the screw rod 6 extending out of the groove 5 in this embodiment is respectively fixedly mounted with a hand wheel 40, and the hand wheel 40 is coaxially arranged with the corresponding screw rod 6. It is more convenient and labor-saving to turn the corresponding screw rod 6 through the hand wheel 40.

[0020] Further, as shown in the figure, the inner circumference of the arc plate 4 in this embodiment is fixedly installed with a rubber pad 50, and the rubber pad 50 is coaxially arranged with the arc plate 4. The rubber pad 50 can increase the friction between the arc plate 4 and the outer circumference of the building structure, so that the device can be installed on the building structure more stably.

[0021] Furthermore, as shown in the figure, the rubber pad 50 in this embodiment is soft rubber. Soft rubber has a rough surface, a large friction coefficient, and good tear resistance and impact resistance.

Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
