DETAILED DESCRIPTION

[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0028] The preferred embodiment of the safety grating protection mechanism provided by the utility model is as follows: Figures 1 to 6 Shown is a safety grating protection mechanism, comprising a protection frame 1, with splicing components 3 arranged on both sides of the protection frame 1, support components 5 arranged at equal intervals on the top of one side of the inner wall of the protection frame 1, and a safety grating body 4 fixedly connected to the lower end of the other side of the inner wall of the protection frame 1.

[0029] The splicing component 3 includes a slot 301, which is provided on one side of the inner wall of the protection frame 1, and a reserved slot 303 is provided on one side of the back side of the protection frame 1. The inner wall of the reserved slot 303 is movably connected with a fixing bolt 304 extending to the inside of the slot 301. A clamping block 302 is fixedly connected to the other side of the protection frame 1, and a bolt hole 306 is provided on one side of the back side of the clamping block 302. By utilizing the engagement between the clamping block 302 and the inside of the slot 301, and then utilizing the engagement between the fixing bolt 304 and the thread inside the bolt hole 306, the protection frames 1 can be quickly spliced ​​and assembled, which is convenient for meeting the protection requirements of safety grating bodies 4 of different lengths, and avoiding the inconvenience of splicing and assembling the traditional protection frame 1 due to the long length of the safety grating body 4.

[0030] In this embodiment, a locking structure is formed between the locking block 302 and the inside of the locking slot 301. The cross-sections of the locking slot 301 and the locking block 302 are inverted convex. The locking between the inverted convex locking block 302 and the inside of the locking slot 301 is used to improve the stability of the initial locking and fixing between the protective frame 1.

[0031] In this embodiment, a sealing ring 305 is fixedly connected to one end of the surface of the fixing bolt 304, and the cross-section of the sealing ring 305 is O-shaped. The O-shaped sealing ring 305 is used to improve the clamping strength between the nut of the fixing bolt 304 and the inner wall of the reserved groove 303, thereby preventing the fixing bolt 304 and the bolt hole 306 from loosening the threads and affecting the firmness and stability of the splicing installation between the protection frames 1.

[0032] In this embodiment, a threaded disassembly structure is formed between one end of the fixing bolt 304 and the inside of the bolt hole 306. A cross groove is provided on the back of the fixing bolt 304. The fixing bolt 304 cooperates with the thread inside the bolt hole 306 to achieve limited fixation or separation of the clamping block 302 and the inside of the clamping slot 301. Example 2

[0033] On the basis of Example 1, a preferred embodiment of the safety grating protection mechanism provided by the present utility model is as follows: Figures 1 to 6As shown: the support assembly 5 includes a support seat 501, which is fixedly connected to the top of one side of the inner wall of the protection frame 1 at equal intervals. A fixed groove 505 is opened inside the support seat 501, and a damper 503 is fixedly connected to the inner bottom wall of the fixed groove 505. A sliding block 506 is fixedly connected to the top of the damper 503. A fixed spring 504 is wound around the surface of the damper 503 at the bottom of the sliding block 506. The bottom end of the fixed spring 504 is fixedly connected to the inner bottom wall of the fixed groove 505. A buffer rod 502 extending to the outside of the support seat 501 is fixedly connected to the top of the sliding block 506. The top of the buffer rod 502 is fixedly connected to the upper end of the inner wall of the protection frame 1. The fixed spring 504 is used to absorb external potential energy, and then the damper 503 is used to consume the elastic potential energy absorbed by the fixed spring 504. Then, the damper 503 and the fixed spring 504 can be used to further support and buffer the upper end of the protection frame 1, thereby improving the pressure-bearing effect of the upper end of the protection frame 1 and its own structural strength.

[0034] In this embodiment, a sliding structure is formed between the sliding block 506 and the interior of the fixed groove 505. The cross-section of the fixed groove 505 and the sliding block 506 is cross-shaped. The sliding of the cross-shaped sliding block 506 and the interior of the fixed groove 505 is utilized to improve the stability of the force-bearing sliding of the buffer rod 502.

[0035] In this embodiment, one end of the buffer rod 502 is welded to the surface of the protective frame 1 to form an integrated structure, and the angle between the buffer rod 502 and the upper end of one side of the protective frame 1 is sixty degrees. The buffer rod 502 that is welded to the upper end of one side of the protective frame 1 and is inclined can facilitate forming a triangle between the protective frame 1, thereby further strengthening the support of the upper end of the protective frame 1.

[0036] In addition, fluorescent strips 2 are fixedly connected at equal intervals on one side of the surface of the protective frame 1. The inclination angle of the fluorescent strips 2 to the vertical direction is twenty degrees. The inclined fluorescent strips 2 are used to make the protective frame 1 emit fluorescence at night, which is convenient for users to know and reduces stepping on the protective frame 1 in poor light conditions.

[0037] The working principle and use process of the utility model are as follows: first, when the safety grating body 4 is longer than the protection frame 1, the clamping block 302 can be clamped into the inside of the clamping slot 301, and then the fixing bolt 304 can be inserted into the inside of the reserved slot 303 and screwed into the inside of the bolt hole 306, so as to achieve a firm clamping and fixing between the clamping block 302 and the inside of the clamping slot 301, and then the protection frames 1 can be quickly spliced ​​and assembled, which is convenient for meeting the protection requirements of safety grating bodies 4 of different lengths and improving its practicality. In addition, the sealing ring 305 can be used to improve the clamping firmness of the nut of the fixing bolt 304 and the inner wall of the reserved slot 303, so as to avoid the loosening of the threads of the fixing bolt 304 and the inside of the bolt hole 306, which affects the firmness and stability of the splicing installation between the protection frames 1;

[0038] Afterwards, the safety grating body 4 is installed on the lower end of the inner wall of the protection frame 1 through external bolts, and then the protection frame 1 is installed and fixed at a suitable position. Afterwards, the safety grating body 4 is protected by the protection frame 1, and when the upper end of the protection frame 1 is stepped on or objects fall, the upper end of the protection frame 1 deflects to absorb part of the potential energy, and the buffer rod 502 slides to drive the sliding block 506 to slide inside the fixed groove 505 to compress the damper 503 and the fixed spring 504. At this time, the fixed spring 504 is used to absorb external potential energy, and then the damper 503 is used to consume the elastic potential energy absorbed by the fixed spring 504, and then the damper 503 and the fixed spring 504 can be used to further support and buffer the upper end of the protection frame 1 to avoid the safety grating body 4 from slipping due to hard collision with external force and causing signal loss.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
