[0032] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] See also Figure 1-Figure 6A multi-directional adjustable guardrail structure includes a guardrail body 1, the guardrail body 1 includes a fixed base 2 for fixing the entire guardrail on the ground, a fixed guardrail 3 is welded and fixed on the top surface of the fixed base 2, and a sliding guardrail 4 is slidably connected to the top surface of the fixed base 2 through a slide groove 21. A rotating slider 42 is rotatably installed on the bottom surface of a longer column at one end of the sliding guardrail 4 through a bearing, and a telescopic support seat 5 is fixedly installed on the bottom surface of a shorter column at the other end of the sliding guardrail 4. The sum of the height of the telescopic support seat 5 when compressed to the shortest state and the height of the shorter column is equal to the height of the longer column, and the sum of the height of the telescopic support seat 5 when stretched to the longest state and the height of the shorter column is equal to the sum of the height of the longer column and the height of the fixed base 2. The fixed guardrail 3 and the sliding guardrail 4 are slidably connected on the opposite sides thereof with a subordinate guardrail 6 whose height can be adjusted in multiple gears.

[0035] In this embodiment, both ends of the slide groove 21 are closed, and the longitudinal cross-sections of the slide groove 21 and the rotating slider 42 are both inverted T-shaped and have matching sizes. The closure of both ends of the slot of the slide groove 21 can prevent the sliding guardrail 4 from separating from the guardrail body 1, and the rotating slider 42 provides the necessary conditions for the sliding guardrail 4 to change its angle.

[0036] In this embodiment, bolt holes 7 are provided at both ends of the top cross bars of the fixed guardrail 3 and the sliding guardrail 4. The end of the top cross bar of the sliding guardrail 4 close to the longer column has no contact with the fixed guardrail 3. When the sliding guardrail 4 slides out of the fixed base 2, it can be fixedly connected to the bolt holes 7 at the corresponding parts of the fixed guardrail 3 by passing bolts through the bolt holes 7, thereby ensuring the stability of this embodiment. The non-contact design provides the necessary space for the sliding guardrail 4 to realize multi-directional rotation.

[0037] In this embodiment, the top of the sleeve 52 is welded and fixed to the bottom surface of the shorter column of the sliding guardrail 4, the movable base 51 is equal to the height of the sleeve 52, and the inner cross-sectional dimension of the movable base 51 is greater than or equal to the cross-sectional dimension of the sleeve 52, so as to ensure the overall stability of the sliding guardrail 4 and the guardrail body 1 by adjusting the height of the telescopic support seat 5;

[0038] In addition, an extension plate 511 extending outward and being used to be fixed to the ground by bolts is integrally formed on the outer side of the bottom of the movable base 51. A card interface 512 is provided at each of the four vertical side walls of the movable base 51 near the upper corners. A spring card buckle 521 is slidably connected at each of the four corners of the four vertical side walls of the sleeve 52. The spring card buckle 521 is used in conjunction with the card interface 512 at the corresponding position. Figure 4 As shown, the shape of the telescopic support seat 5 is preferably a cubic structure, which is the most common, simple, easy to produce, reduces costs, and is also convenient to install. It can also be a cylinder or other polygonal structure, such as a triangle, a pentagon, etc.;

[0039] It is further necessary to explain that the distance between the two spring clips 521 on the same vertical line on the sleeve 52 is equal to the height of the fixed base 2. When the telescopic support seat 5 is compressed to the shortest state, the bottom surfaces of the movable base 51 and the sleeve 52 are flush with the top surface of the fixed base 2; when the telescopic support seat 5 is stretched to the longest state, the bottom surface of the movable base 51 is flush with the bottom surface of the fixed base 2. When the card interface 512 is engaged with the spring clip 521 at the upper end of the sleeve 52, the telescopic support seat 5 is in the shortest state, and when the card interface 512 is engaged with the spring clip 521 at the lower end of the sleeve 52, the telescopic support seat 5 is in the longest state. In this way, the length of the telescopic support seat 5 is adjusted to ensure the overall stability of the sliding guardrail 4 and the guardrail body 1. At the same time, the temporary fixed connection between the extension plate 511 and the ground also ensures the overall stability of the guardrail body 1.

[0040] In this embodiment, the fixed guardrail 3 and the sliding guardrail 4 have the same length and height. A first T-slot 31 is provided on the side wall of the two end columns of the fixed guardrail 3 facing away from the sliding guardrail 4. A second T-slot 41 is provided on the side wall of the longer column and the shorter column of the sliding guardrail 4 facing away from the fixed guardrail 3. The first T-slot 31 and the second T-slot 41 have the same size. The provision of the first T-slot 31 and the second T-slot 41 provides feasibility for adjusting the height of the subordinate guardrail up and down. The same size structure ensures the stability and overall aesthetics of the guardrail body 1, and is convenient for large-scale production, thereby reducing production costs.

[0041] In this embodiment, a plurality of bolt holes 7 are provided on the vertical bars at the ends of the two ends of the subordinate guardrail 6, which are arranged on the same vertical line and are evenly spaced. Both ends of the lower crossbar of the subordinate guardrail 6 are provided with T-shaped sliding blocks 61 for slidingly connecting with the first T-shaped slot 31 or the second T-shaped slot 41. These limiting conditions provide necessary conditions for the height of the subordinate guardrail 6 to be controlled and slidable in multiple gears, thereby ensuring the feasibility of this embodiment.

[0042] It should be supplemented that when the subordinate guardrail 6 slides up and down until one of the bolt holes 7 corresponds to the position of the bolt hole 7 at the end of the uppermost cross bar of the fixed guardrail 3 or the sliding guardrail 4 on the same side, bolts can be passed through the two connected bolt holes 7 in sequence and fixed, thereby ensuring the stability of the guardrail body 1.

[0043] Working principle: When the multi-directional adjustable guardrail structure of this embodiment is in use, the user first places the guardrail body 1 on a relatively flat ground. To ensure its stability, the sliding guardrail 4 slidably connected to the fixed base 2 can be pushed to the closed position at the end of the slide groove 21 according to needs, and then the telescopic support seat 5 is clamped and stretched to ensure the stability of the two ends of the sliding guardrail 4. At this time, bolts are passed through the bolt holes 7 at the corresponding positions of the parallel parts of the fixed guardrail 3 and the sliding guardrail 4, and then the two are fixedly connected, which is convenient for transportation and transfer, and the sliding guardrail 4 will not slide by itself during the transfer process; in the specific use process, first remove the bolts used for limiting between the fixed guardrail 3 and the sliding guardrail 4, then adjust the direction of the sliding guardrail 4 according to needs, and then use bolts to pass through the bolt holes on the extension plate 511 to fix the sliding guardrail 4 to the ground, and finally adjust the required height of the subordinate guardrail 6 and use bolts to pass through the bolt holes 7 corresponding to the subordinate guardrail 6 and the fixed guardrail 3 or the sliding guardrail 4 and fix it.

[0044] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) to form a technical solution.
