Description

Technical Field

[0001] The present invention relates to the technical field of guardrails, and in particular to a safety railing fixing structure. Background Art

[0002] Safety railings mainly refer to municipal guardrails, traffic isolation guardrails, highway W-shaped guardrails, and corrugated guardrails (S-level or SB-level). The main functions of safety guardrails are: first, they are used to prevent vehicles from driving off the road; second, the moving trajectory of the vehicle collision safety link should be able to transition smoothly, so that the vehicle returns to the normal driving direction and avoids secondary accidents; third, once a vehicle collides with the safety guardrail, it can reduce the damage to the driver and passengers.

[0003] The existing safety railings have insufficient anti-collision performance. Once a vehicle hits the safety railing, the buffering effect is too small to better protect the personal safety of the occupants of the vehicle. At the same time, most safety railings have a simple structure. When used on a large scale, they need to be spliced ​​together by several safety railings. When not in use, it is not convenient to disassemble and place them separately, and it is inconvenient to disassemble them. Therefore, there is an urgent need for a safety guardrail that can buffer the impact force and is easy to disassemble for independent or splicing use. Summary of the invention

DETAILED DESCRIPTION

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and thus only show the components related to the present invention.

[0023] Please refer to Figure 1-8 A safety railing fixing structure includes a guardrail body and a splicing plate 1 outside the guardrail body, the guardrail body includes a plurality of columns 3, a plurality of cross bars 31 are evenly arranged between each adjacent two columns 3, the columns 3 are elastically connected to the splicing plate 1, and each adjacent two splicing plates 1 are detachably connected.

[0024] The top of the splicing plate 1 is provided with a guide rod 2 extending outward, the guide rod 2 is fixedly connected to the splicing plate 1, and the column 3 is provided with a guide groove 32 on the side close to the splicing plate 1, and the guide rod 2 corresponds to the guide groove 32 one by one.

[0025] In the solution of the present invention, the splicing plate 1 and the column 3 are elastically connected via a shock-absorbing spring 4 , one end of the shock-absorbing spring 4 is fixed to the column 3 , and the other end is fixed to the splicing plate 1 .

[0026] The guide rod 2 plays a positioning role. When the column 3 or the crossbar 31 is hit, the whole can move toward the splicing plate 1 and squeeze the shock-absorbing spring 4, which can effectively buffer the impact.

[0027] In this embodiment, a splicing mechanism 5 is provided on one side of the splicing plate 1, and a socket 11 corresponding to the splicing mechanism 5 is provided on the other side. Two adjacent splicing plates 1 are spliced ​​together through the splicing mechanism 5 and the socket 1, so that they can be spliced ​​according to the maintenance length to meet the usage requirements.

[0028] Specifically, the splicing mechanism 5 includes an extension box 51 with a hollow interior, a through cavity 52 is provided on the outer side of the extension box 51, a rotatable limit block 56 is provided in the through cavity 52, and the limit block 56 is elliptical. Under normal circumstances, the limit block 56 is arranged in the through cavity 52, and the limit block 56 extends out of the upper and lower sides of the through cavity 52 after rotating 90°.

[0029] That is to say, before splicing, the elliptical limit block 56 is horizontally arranged and hidden in the through cavity 52, and the extension box 51 can be smoothly inserted into the socket 11; when the limit block 56 is rotated 90°, the two ends of the limit block 56 extend out of the through cavity 52, playing a locking and limiting role to prevent the two splicing plates from separating after splicing.

[0030] An annular limiting groove 111 is provided inside the insertion hole 11, and the limiting block 56 rotates in the annular limiting groove 111. After rotation, the extending limiting block 56 can be stuck in the annular limiting groove 111, which plays a locking and limiting role, thereby increasing the stability of the overall structure.

[0031] In the solution of the present invention, a partition 54 is provided at the end of the extension box 51, and the through cavity 52 is provided on the outside of the partition 54. A rotatable first transmission shaft 55 is provided in the partition 54. One end of the first transmission shaft 55 passes through the partition 54 and is fixedly connected to the limit block 56, and the other end is provided with a first bevel gear 57. The first bevel gear 57 cooperates with the second bevel gear 59 for transmission. The second bevel gear 59 is provided with an integral second transmission shaft 58. The second transmission shaft 58 is provided with a driving rod 53. The driving rod 53 passes through the extension box 51 and extends upward. When the driving rod 53 rotates, it drives the limit block 56 to rotate.

[0032] That is to say, the first transmission shaft 55 and the second transmission shaft 58 are transmitted through the cooperation of the first bevel gear 57 and the second bevel gear 59. Since the driving rod 53 is arranged on the second transmission shaft 58, the limit block 56 is arranged on the second transmission shaft 58; therefore, when the driving rod 53 (the second transmission shaft 58) rotates, the second transmission shaft 58 and the limit block 56 rotate accordingly, so that the limit block 56 is rotated and locked in another splicing plate 1, thereby increasing the splicing stability.

[0033] The overall fixed structure of the safety railing can achieve shock absorption and buffer impact force, and the safety railing as a whole can be disassembled and used individually or in splicing. It is suitable for various scenarios and meets usage needs.

[0034] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
