Novel protection device based on road and bridge protection

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0025] See Figure 1-5 , The present invention provides a technical solution: a new type of protection device based on road and bridge protection, including a first fixed ring 1 and a second fixed ring 2, the tops on both sides between the first fixed ring 1 and the second fixed ring 2 Both the bottom and the bottom are movably connected by a fixing bolt 3. A fixing nut 4 is threaded on one side of the fixing bolt 3, and the middle of the surface of the first fixing ring 1 and the second fixing ring 2 pass through the limit bolt 5, two limit bolts 5 The ends far away from the first fixing ring 1 and the second fixing ring 2 are threadedly connected with a protective box 6. The surface of the protective box 6 and the connection with the limit bolt 5 is provided with a threaded groove 7 on the surface of the protective box 6 A movable hinge 8 is fixedly connected to the top of the movable hinge 8, a protective cover 9 is fixedly connected to the surface of the movable hinge 8, the bottom of the protective cover 9 and the top of the protective box 6 are fixedly connected with a magnet 10, and the two magnets 10 are in contact with each other, The magnets 10 are attracted to each other to prevent the protective cover 9 from opening, and it is considered that the force is large, and it can be pulled open directly.

[0026] In the present invention, the two sides of the top of the protective cover 9 and the side away from the movable hinge 8 are fixedly connected with fixed posts 11, and a handle is fixedly connected between the two fixed posts 11, and the movable hinge 8 is a movable hinge. To connect the protective cover and the protective box 6.

[0027] In the present invention, a connecting rod 12 is fixedly connected to the middle portions on both sides between the first fixing ring 1 and the second fixing ring 2, and the ends of the two connecting rods 12 away from the first fixing ring 1 and the second fixing ring 2 are both fixed. It penetrates the protective box 6 and extends to the inner cavity of the protective box 6.

[0028] In the present invention, one end of the connecting rod 12 located in the inner cavity of the protective box 6 is fixedly connected with an extruded plate 13, and the side of the extruded plate 13 close to the protective box 6 is in contact with the inner surface of the protective box 6.

[0029] In the present invention, both sides of the surface of the first fixing ring 1 and the second fixing ring 2 and the side away from the protective box 6 are fixedly connected with a reflector 14 which is a mirror-like material for reflecting light.

[0030] In the present invention, a through hole is opened in the middle of the surface of the protective cover 9, and the inner surface of the through hole in the middle of the top of the protective cover 9 is fixedly connected with a glass visual plate 15 which is a tempered glass plate, which can be seen through and used for observation .

[0031] In the present invention, the inner surface of the extrusion plate 13 is fixedly connected with a soft rubber pad 16, and the middle of the bottom of the protective box 6 is provided with an opening. The soft rubber pad 16 prevents the extrusion plate 13 from being excessively stressed and causing internal screw damage.

[0032] In the present invention, the number of reflectors 14 is eight, and each of them is uniform in size and arranged on both sides of the middle of the outer surface of the first fixing ring 1 and the second fixing ring 2.

[0033] When in use, first select the protective equipment suitable for the size of the bridge screw to be protected. First, lift the protective cover 9 by the handle and the fixed post 11, and then the movable hinge 8 will prevent the protective cover 9 from falling , Then screw the fixing bolt 3 to make the first fixing ring 1 and the second fixing ring 2 movable, then pull the first fixing ring 1 and the second fixing ring 2 outward to the limit, and then put the whole device on the screw , The nut on the top of the screw is in the inner cavity of the protective box 6. At this time, the fixing bolt 3 can be reversed to tighten the first fixing ring 1 and the second fixing ring 2, and pushing the pressing plate 13 to the inner screw Squeeze to achieve the effect of fixing, then close the protective cover 9 so that the magnet 10 will attract the protective cover 9. At this time, you can turn the limit bolt 5 to connect the first fixing ring 1 and the second fixing ring 2 is fixed with the protective box 6 so that the protective device is installed. The light source projected by the reflector 14 is reflected at night for display, and the glass visible plate 15 on the top of the protective cover 9 is used to check the internal screw condition.

[0034] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply one of these entities or operations. There is any such actual relationship or order between. Moreover, the terms "include", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes those that are not explicitly listed Other elements of, or also include elements inherent to this process, method, article or equipment.

[0035] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. And variations, the scope of the present invention is defined by the appended claims and their equivalents.
