Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to an adjustable metal guardrail. Background Technique

[0002] At present, the most widely used metal guardrail is the zinc steel guardrail. The zinc steel guardrail refers to the guardrail poles made of zinc alloy materials for different parts with different functions. Since its surface layer is treated by electrostatic spraying later, it has the advantages of high strength, high hardness, beautiful appearance, bright color, etc., and has become the mainstream product used in residential areas, factories, schools, road traffic, etc. Traditional guardrails use iron bar materials, which require the help of welding and other process technologies, and are soft in texture, easy to rust, and single in color. The zinc steel balcony guardrail perfectly solves the shortcomings of traditional guardrails and has a moderate price, becoming an alternative product to traditional various guardrail materials. The zinc steel guardrail is assembled by a non-welded interpenetrating combination method (there are also processes that require partial welding, but zinc supplementation treatment needs to be done before spraying). The substrate thickness is 2-3 times that of stainless steel, and more than 500 colors are available for selection. The surface is treated with polyester antioxidant powder electrostatic spraying, enhancing the antioxidant, anti-ultraviolet, weather-resistant and corrosion-resistant capabilities of the guardrail. Products mainly made of zinc steel used in building guardrails specifically include: balcony guardrails, protective windows, staircase handrails, fences, garden fences, shutters, air conditioner fences, and road guardrails.

[0003] After the existing metal zinc steel guardrails are assembled, they are all of fixed specifications and styles. Since different sites have different requirements for the height of the guardrails, and the existing guardrails cannot be adjusted in height according to actual needs, they cannot meet the customer's requirements for height, thus reducing the universality of guardrail installation. Content of the Utility Model

[0004] The purpose of the utility model is to provide an adjustable metal guardrail to solve the problems mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an adjustable metal guardrail, including at least two support columns, with a fence arranged between adjacent support columns. The support column is an inner hollow shell structure with one end open and one end closed. Two symmetrically distributed slot openings are provided at both non-adjacent side wall ends of the support column; two symmetrically distributed clamping components are inserted along the length direction of the slot openings, and both ends of the clamping components are respectively in contact with the two outer side walls of the support column; at least one set of fasteners screwed on the outer wall of the support column, and the fasteners include two screws symmetrically screwed on the support column; when the screws are turned, the tail ends of the screws will push the clamping components to move horizontally along the width direction of the slot openings, so that the two clamping components clamp and limit one end of the fence.

[0006] As a further solution of the present utility model: The clamping assembly includes: a plate body; limiting strips symmetrically arranged at both ends of the plate body, and the limiting strips are in a "T" shape; a plurality of card slots equidistantly opened on one side wall of the limiting strip, and the slot width of the card slot is adapted to the cross bar on the fence.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described 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.

[0021] Please refer to Figures 1 to 5 , in the embodiment of the present invention, an adjustable metal guardrail includes at least two support columns 1, a fence 2 is arranged between adjacent support columns 1, the support column 1 is an inner hollow shell structure with one end open and one end closed, and two symmetrically distributed notches 7 are opened at both non-adjacent side wall ends of the support column 1; two symmetrically distributed clamping assemblies 5 are inserted along the length direction of the notch 7, and both ends of the clamping assembly 5 are respectively attached to the outer side walls of the support column 1; at least one group of fasteners 8 screwed on the outer wall of the support column 1, the fastener 8 includes two screws symmetrically screwed on the support column 1; when the screws are turned, the tail ends of the screws will push the clamping assembly 5 to move horizontally along the width direction of the notch 7, so that the two clamping assemblies 5 clamp and limit one end of the fence 2.

[0022] In this embodiment: Since the existing metal zinc steel guardrails are all of fixed specifications and styles after assembly, and since different sites have different requirements for the height of the guardrails, the guardrails cannot be adjusted in height according to actual needs. Therefore, the requirements of customers for height cannot be met, and the universality of guardrail installation is reduced. Therefore, in this solution, the clamping assemblies 5 on two adjacent support columns 1 are used to clamp and fix both ends of the fence 2, and by adjusting the position height of the fence 2 relative to the support column 1, the position height of the entire metal guardrail is changed to meet different height requirements; the guardrail is convenient and firm to splice and install, and has a wide range of applicable sites.

[0023] Specifically, the overall height of the guardrail is affected by the fence 2. Therefore, in this solution, the overall height of the guardrail is changed by adjusting the position height of the fence 2 relative to the support column 1. There are two cases for the change in the position height of the fence 2. One is the ground - clearance type, where there is a certain distance between the lower end of the fence 2 and the foundation, and the top of the fence 2 is higher than or equal to the top of the support column 1. At this time, the overall height of the guardrail is relatively high. The other is the ground - contact type, where the lower end of the fence 2 contacts or is inserted into the foundation. At this time, the top height of the fence 2 will be lower than the top height of the support column 1, and the overall height of the guardrail will be reduced.

[0024] When the position height of the fence 2 is determined, the fastener 8 is turned to push the two clamping components 5 closer to each other until the two clamping components 5 clamp and fix the fence 2.

[0025] Please refer specifically to Figure 4 , the plate body 501; the limiting strips 502 symmetrically arranged at both ends of the plate body 501, the limiting strips 502 having a "T" - shaped structure; a plurality of card slots 503 equidistantly opened on one side wall of the limiting strip 502, the slot width of the card slots 503 being adapted to the cross - bar on the fence 2; the width of the limiting strip 502 being greater than the width of the slot opening 7.

[0026] In this embodiment: The clamping component 5 mainly includes a plate body 501, limiting strips 502 and card slots 503. This clamping structure can block the slot opening 7, making the overall support column 1 more beautiful. The card slots 503 can limit the offset of the cross - bar on the fence 2, and thus fix and limit the fence 2 more firmly.

[0027] It should be noted that multiple fasteners 8 can be provided to limit and fix multiple areas such as both ends and the middle of the plate body 501, further improving the clamping stability of the clamping component 5.

[0028] Please refer specifically to Figure 1 , a cap 3 is sleeved on the open end of the support column 1, and a base 4 is fixedly connected to the sealed end of the support column 1.

[0029] In this embodiment: Using the cap 3 to cover the open end of the support column 1 not only makes the overall support column 1 more beautiful, but also prevents rainwater, dust and other sundries from entering the support column 1.

[0030] Please refer specifically to Figure 1 and Figure 5 , a protective component 6 is provided on the outside of the fastener 8 and surrounds the support column 1 for shielding and covering the fastener 8. The protective component 6 includes two connecting pieces 601, and a receiving groove 602 is opened on the side wall of each of the two connecting pieces 601 close to the fastener 8. The two connecting pieces 601 are fixedly connected by anti - theft bolts.

[0031] In this embodiment: By providing a protective component 6 outside the fastener 8, it is mainly to shield the fastener 8 to prevent the fastener 8 from being easily disassembled by lawbreakers. Therefore, in this solution, the fastener 8 is wrapped by two connecting members 601, and at the same time, the two connecting members 601 are fixedly connected by anti-theft bolts, preventing the fastener 8 from being exposed to the outside, thereby improving the safety factor of the guardrail.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
