Technical Field

[0001] This utility model relates to the field of safety railing technology, and in particular to an adjustable safety railing structure. Background Technology

[0002] Safety barriers are safety devices installed in the center or on both sides of a road to regulate the direction of vehicles and prevent out-of-control vehicles from running off the road. They play a significant role in regulating vehicle trajectories and reducing the severity of traffic accidents. Currently, safety barriers are widely used on highways.

[0003] A highway safety guardrail structure with announcement number CN220503745U includes two vertically arranged support columns. A fixed mounting plate is installed at the bottom of each support column. An upper support connecting plate is installed between the support columns, and a lower support connecting plate is installed between the support columns below the upper support connecting plate. Several baffles are equidistantly arranged horizontally between the upper and lower support connecting plates. A water storage tank is installed below the lower support connecting plate, with one end of the water storage tank connected to the fixed mounting plate. The advantages of this utility model are: the design is reasonable, the structure is simple and stable, and it is highly practical; by rotating the rectangular water tank to different angles, both sides of the guardrail can be cleaned separately. It can also spray water on the road surface when the weather is hot to protect the road surface. In addition, the water storage tank can collect and store rainwater, making rational use of resources, saving energy and protecting the environment, making it suitable for widespread use.

[0004] However, the above-mentioned highway safety guardrail structure still has the following defects in use: In the use of the above-mentioned existing technology, since the size of the supporting column and the baffle is fixed, it is inconvenient to adjust its height according to the actual use situation, which not only increases the use cost, but also reduces its practicality. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable safety railing structure to solve the problem mentioned in the background art that the height of the existing safety railing structure is inconvenient to adjust during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable safety railing structure, comprising two support columns, a horizontal plate, and a base, wherein the bottom ends of the two support columns are each welded with a base, and a horizontal plate is fixed between the two support columns;

[0007] The top of the horizontal plate is uniformly welded with a stop bar. The support column and the stop bar are both slidably equipped with an extension rod. One of the extension rods is equipped with an adjustment mechanism. Limit grooves are opened on both sides of the support column. Two inserts are welded to one side of one support column, and the inserts are equipped with slots. A splicing block is fixed to one side of the other support column, and the splicing block is equipped with a slot. The top of the splicing block is equipped with a splicing mechanism. The top of the extension rod is welded with a fixing plate.

[0008] When using an adjustable safety railing structure based on this technical solution, the user can easily adjust its height according to actual usage conditions by means of an adjustment mechanism in conjunction with a limit groove, thereby improving its practicality.

[0009] Preferably, the adjusting mechanism includes a fixing block, which is disposed inside the extension rod. A return spring is disposed inside the fixing block, and baffles are fixed at both ends of the return spring. A limit block is disposed on one side of each baffle.

[0010] Preferably, the baffle is provided in two sets, each set having two baffles, and the two baffles are symmetrically distributed, with the outer edges of both sets of baffles slidingly attached to the inner wall of the fixing block.

[0011] Preferably, there are two reset springs, which are symmetrically distributed and are both in a stretched state inside the fixing block.

[0012] Preferably, the splicing mechanism includes an installation block, which is disposed at the top of the splicing block. Guide grooves are provided on both sides inside the installation block, and guide blocks are slidably disposed inside the guide grooves. A movable plate is disposed inside the installation block, and a locking block is fixed at the top of the movable plate. An adjusting rod is fixed at the top of the movable plate, and one end of the adjusting rod extends to the outside of the installation block.

[0013] Preferably, the guide block slides inside the guide groove, and the movable plate is slidably connected to the mounting block through the guide block and the guide groove.

[0014] Preferably, the limiting groove is provided in multiple sets, each set of the limiting groove is provided with three, and the limiting grooves in each set are distributed at equal intervals.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the adjustable highway safety guardrail structure is not only easy to adjust its height, but also easy to splice;

[0016] 1. By pressing the limiting block, the limiting block is disengaged from the limiting groove and retracted into the fixing block, thereby releasing the limitation on the extension rod. Then, the fixing plate is pulled to pull the extension rod out from the support column and the stop bar. The above operation allows the user to adjust the height up and down according to the actual use, thereby saving costs and manpower, increasing the user experience, and thus increasing its practicality.

[0017] 2. By turning the adjusting rod, the locking block moves downward under the action of the movable plate, thereby inserting the locking block into the slot. The above operation makes it easy to fix the locking block, which facilitates the overall splicing and installation, thus improving the ease of installation.

[0018] By having the guide block slide inside the guide groove, the moving plate can be limited to prevent it from shifting position during movement, thus affecting subsequent operations. On the other hand, the moving plate can also be guided to improve its stability during movement. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Please see Figures 1-5 The present invention provides the following technical solution:

[0028] Example 1: To address the problem of inconvenience in adjusting the height during use in the prior art, the following solution is disclosed. Please refer to the details below. Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an adjustable safety railing structure includes two support posts 1, a horizontal plate 2, and a base 4. The base 4 is welded to the bottom of each of the two support posts 1. The horizontal plate 2 is fixed between the two support posts 1. Stop bars 3 are evenly welded to the top of the horizontal plate 2. Extension rods 7 are slidably arranged inside both the support posts 1 and the stop bars 3. An adjustment mechanism 6 is arranged inside one of the extension rods 7. The adjustment mechanism 6 includes a fixing block 604, which is disposed inside the extension rod 7. The fixing block 604 contains... A return spring 603 is provided, and baffles 602 are fixed at both ends of the return spring 603. A limit block 601 is provided on one side of each baffle 602. There are two sets of baffles 602, and each set of baffles 602 has two baffles. The two baffles 602 are symmetrically distributed. The outer edges of the two sets of baffles 602 are slidably attached to the inner wall of the fixing block 604. There are two return springs 603, which are symmetrically distributed. Both return springs 603 are in a stretched state inside the fixing block 604.

[0029] In this embodiment, when height adjustment is required, pressing the two limiting blocks 601 causes the two baffles 602 to move horizontally relative to each other. Simultaneously, the movement of the baffles 602 compresses the return spring 603, causing it to compress until the limiting blocks 601 exit the limiting groove 8 and retract into the fixing block 604. This releases the restriction on the extension rod 7, allowing the fixing plate 10 to pull the extension rod 7 out of the support column 1 and the baffle 3. After adjustment, the compressive force on the return spring 603 disappears, pushing the baffle 602 to move horizontally, allowing the limiting block 601 to insert into the other limiting groove 8. This operation allows for height adjustment according to actual usage, improving flexibility to accommodate different applications.

[0030] Example 2: This example differs from Example 1 in that it facilitates rapid assembly during use. Therefore, the following solution is disclosed. Please refer to the details below. Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, limit grooves 8 are provided on both sides of the support column 1. Multiple sets of limit grooves 8 are provided, with three grooves in each set, and the grooves 8 are evenly spaced. Two inserts 9 are welded to one side of one support column 1, and each insert 9 has a slot 5 inside. A splicing block 13 is fixed to one side of the other support column 1, and each splicing block 13 has a slot 12 inside. A splicing mechanism 11 is provided at the top of each splicing block 13. The splicing mechanism 11 includes a mounting block 1102, which is located at the top of the splicing block 13. Both sides of the mounting block 1102 have... A guide groove 1106 is provided, and a guide block 1103 is slidably arranged inside the guide groove 1106. A movable plate 1105 is provided inside the mounting block 1102, and a locking block 1104 is fixed to the top of the movable plate 1105. An adjusting rod 1101 is fixed to the top of the movable plate 1105, and one end of the adjusting rod 1101 extends to the outside of the mounting block 1102. The guide block 1103 slides inside the guide groove 1106. The movable plate 1105 is slidably connected to the mounting block 1102 through the guide block 1103 and the guide groove 1106. A fixing plate 10 is welded to the top of the extension rod 7.

[0031] In this embodiment, during use, after adjustment, the insert 9 on one side of the support column 1 is pushed to insert into the splicing block 13 of another support column 1 until the insert 9 and the slot 12 are in contact. Then, the movable plate 1105 is lowered by turning the adjusting rod 1101. At the same time as the movable plate 1105 is lowered, the guide block 1103 is placed inside the guide groove 1106 to limit the movement of the movable plate 1105. At the same time as the movable plate 1105 is lowered, the locking block 1104 is lowered synchronously until the locking block 1104 is inserted into the slot 5, which facilitates the limiting of the insert 9. The above operation facilitates the splicing and installation of the whole, thereby improving its practicality.
