Description

Technical Field

[0001] The utility model belongs to the technical field of machinery, and particularly relates to a quick-installation guardrail. Background Art

[0002] In the traditional guardrail installation method, one is to fix it by connecting to the ground. In this way, it is necessary to drill holes in the ground. However, in exhibition halls or other specific places, this is not allowed. There is another method, that is, first add a counterweight to the bottom of the guardrail, use a relatively slender pipe to support it at the upper part, and then connect the fabric in the middle. However, when there are a large number of people, the guardrail installed in this way is easily knocked down. Summary of the Invention

[0003] The purpose of the utility model is to address the above problems existing in the prior art and propose a quick-installation guardrail with the characteristics of stability and convenient installation.

[0004] The purpose of the utility model can be achieved by the following technical solutions:

[0005] A quick-installation guardrail includes a plurality of columns and a plurality of rolling curtain components. The middle part of the column is hollow, and the bottom of the column has a first support part in a horn shape. A plurality of connection holes are provided on the column. The rolling curtain component includes a first connecting rod, a second connecting rod, and a curtain. The two ends of the curtain are respectively fixed on the first connecting rod and the second connecting rod. The two ends of the first connecting rod can be respectively inserted into the connection holes of two columns, and the two ends of the second connecting rod can be respectively inserted into the connection holes of two columns.

[0006] In the above quick-installation guardrail, the cross-section of the column is square, and a plurality of the connection holes are distributed on the four surfaces of the column.

[0007] In the above quick-installation guardrail, each surface of the column has two rows of connection holes arranged along the height direction, and the two rows of connection holes are arranged in a staggered manner.

[0008] In the above quick-installation guardrail, a bottom plate is arranged at the lower end of the first support part, and positioning holes are provided on the bottom plate.

[0009] In the above quick-installation guardrail, a plurality of through holes are provided on the bottom plate around the positioning holes.

[0010] In the above quick-installation guardrail, an opening is provided on the first support part.

[0011] In the above quick-installation guardrail, the top end of the column has a second support part in a horn shape.

[0012] In the above quick-installation guardrail, the columns, the first connecting rod, and the second connecting rod are made of aluminum alloy material.

[0013] Compared with the prior art, the present application has the following advantages:

[0014] In the present application, the quick-installation guardrail mainly relies on the cooperation between the columns and the rolling curtain assembly to achieve its protective function. As a supporting structure, the trumpet-shaped first supporting part at the bottom of the column can increase the contact area with the placement plane and enhance stability. The hollow design in the middle of the column may reduce its own weight while ensuring a certain strength. The first connecting rod and the second connecting rod of the rolling curtain assembly are quickly connected and assembled with the column by inserting into the connection holes opened on the column. Then the curtain can be unfolded between the two connecting rods to play roles such as partitioning and protection. Multiple such columns and rolling curtain assemblies cooperate with each other to construct a guardrail of a certain length and scope. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following further describes the present application in conjunction with the Figure 1 - Figure 2 drawings and specific embodiments:

[0022] First of all, it should be noted here that in the description of this application, when terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and other orientation words appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings. It is only for the convenience of description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to this application; in addition, when terms such as "first", "second", "third" and other numerical quantifiers appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in this application, unless otherwise clearly specified and limited, when terms such as "installation", "connection", "connection" appear, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, an interference fit, a transition fit and other limiting connections, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium; therefore, for those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0023] As Figures 1 to 2 shown, a quick-installation guardrail includes a plurality of columns 2 and a plurality of rolling curtain assemblies 3. The middle part of the column 2 is hollow, and the bottom of the column 2 has a first support part 21 in a horn shape. A plurality of connection holes 22 are opened on the column 2. The rolling curtain assembly 3 includes a first connecting rod 31, a second connecting rod 32 and a curtain 33. Both ends of the curtain 33 are respectively fixed on the first connecting rod 31 and the second connecting rod 32. Both ends of the first connecting rod 31 can be respectively inserted into the connection holes 22 of two columns 2, and both ends of the second connecting rod 32 can be respectively inserted into the connection holes 22 of two columns 2.

[0024] In this application, the quick-installation guardrail mainly relies on the cooperation between the column 2 and the rolling curtain assembly 3 to achieve its protection function. The column 2 is used as a support structure. The horn-shaped first support part 21 at the bottom of the column 2 can increase the contact area with the placement plane and enhance stability. The hollow design in the middle of the column 2 may reduce its own weight while ensuring a certain strength. For the first connecting rod 31 and the second connecting rod 32 of the rolling curtain assembly 3, by inserting into the connection holes 22 opened on the column 2, the quick connection and assembly of the rolling curtain and the column 2 are realized, and the curtain 33 can be unfolded between the two connecting rods to play roles such as separation and protection. Multiple such columns 2 and rolling curtain assemblies 3 cooperate with each other to build a guardrail with a certain length and scope.

[0025] Specifically, the cross-section of the column 2 is square, and a plurality of the connection holes 22 are distributed on the four surfaces of the column 2.

[0026] The connecting holes 22 are distributed on the four surfaces of the column 2, which provides more angle and position options for the installation of the rolling curtain assembly 3. During actual installation, according to the on-site layout, protection requirements, and connection conditions of adjacent components, etc., it is possible to flexibly select from which surface to insert the connecting rod to install the rolling curtain assembly 3, facilitating the handling of various complex installation environments.

[0027] Specifically, each surface of the column 2 has two rows of connecting holes 22 arranged in the height direction, and the two rows of connecting holes 22 are arranged in a staggered manner.

[0028] According to actual needs, it is more convenient to select connecting holes 22 at different heights.

[0029] Specifically, a bottom plate 23 is provided at the lower end of the first support portion 21, and a positioning hole 231 is opened on the bottom plate 23.

[0030] The positioning hole 231 opened on the bottom plate 23 plays a role in precise positioning. When installing the guardrail, by inserting a positioning pin into the positioning hole 231 or cooperating with a corresponding fixing device on the ground 100, the position of the column 2 can be accurately determined, ensuring that the spacing, arrangement direction, etc. between each column 2 meet the requirements of the pre-designed requirements, facilitating the quick and accurate completion of the assembly and construction work of the entire guardrail. As shown in the figure, a limit protrusion 101 is provided on the ground 100 to cooperate with the positioning hole 231 on the bottom plate 23.

[0031] Specifically, a plurality of through holes 232 are opened on the bottom plate 23 around the positioning hole 231.

[0032] By inserting screws into the through holes 232 to connect with the ground 100 or other relevant support structures, a more stable and reliable fixing method can be provided for the column 2.

[0033] Specifically, an opening 211 is opened on the first support portion 21.

[0034] Workers can reach in through the opening 211 and then connect the screws to the ground 100. Also, with the help of this opening 211, workers can see whether the positioning hole 231 corresponds to the limit protrusion 101 on the ground 100.

[0035] Specifically, the top end of the column 2 has a second support portion 24 in a trumpet shape.

[0036] In some special cases, the column 2 can be turned over for use. For example, when the ground 100 where the column 2 is placed is uneven, if there is a bottom plate 23 at the bottom of the column 2, the column 2 is likely to be skewed during the placement process. However, if the second support portion 24 is directly used, since there is no closed structure on the second support portion 24, the column 2 is more likely to remain vertical after placement.

[0037] Specifically, the column 2, the first connecting rod 31, and the second connecting rod 32 are made of aluminum alloy material.

[0038] It should be noted that the above embodiments are only used to illustrate the present application and do not limit the technical solutions described in the present application. Although this specification has described the present application in detail with reference to the above embodiments, those of ordinary skill in the art should understand that those skilled in the art can still modify or equivalently replace the present application. All technical solutions and their improvements that do not depart from the spirit and scope of the present application shall be covered within the scope of the claims of the present application.
