Technical Field
[0001] This utility model relates to the field of guardrail technology, and in particular to a combined fiberglass guardrail for subway use. Background Technology
[0002] At the edge of subway platforms, guardrails can effectively prevent passengers from accidentally falling onto the tracks and avoid serious personal injury accidents. Fiberglass is a composite material made of glass fiber and its products as reinforcing materials and synthetic resin as matrix material, through a certain molding process. Fiberglass has many excellent properties, so it is also used to make guardrails.
[0003] Currently, the guardrails used in subway stations are usually modular structures, with the posts being one part and the railings being a single piece. Because the overall length of the railings is relatively long, they take up a lot of lateral space during transportation and require a lot of screws to assemble during installation, making the installation process cumbersome. Summary of the Invention
[0004] This utility model provides a modular fiberglass guardrail for subway use, which allows for the extension and retraction of the guardrail section, thereby reducing the lateral space occupied during transportation. Moreover, the guardrail does not require many screws to install, making the installation process more convenient and labor-saving.
[0005] In a first aspect, this utility model provides a combined fiberglass guardrail for subway use, specifically comprising: guardrail posts; a set of locking rods installed on the inner side of the top of each guardrail post; two sets of first, second, and third horizontal bars installed between two guardrail posts, wherein the second horizontal bar is slidably installed on the left side of the first horizontal bar, and the third horizontal bar is slidably installed on the left side of the second horizontal bar; a lower guardrail plate is welded to the top of each of the lower first, second, and third horizontal bars, and an upper guardrail plate is welded to the bottom of each of the upper first, second, and third horizontal bars.
[0006] The guardrail post has two rectangular grooves with front openings. One end of the first and third horizontal bars is provided with a rectangular block, which can be embedded in the rectangular groove on the guardrail post and fit tightly against the inner wall of the rectangular groove.
[0007] The first and second crossbars each have a rectangular bar on their left side, and the second and third crossbars each have a rectangular groove inside their right side. The rectangular bars on the left side of the first and second crossbars can slide left and right in the rectangular grooves inside the right side of the second and third crossbars.
[0008] The locking rod has an inverted U-shaped structure, with two round rods at the bottom. The inner side of the guardrail post has two corresponding round holes, and the rectangular blocks at one end of the first and third crossbars also have a through-hole.
[0009] The first and second crossbars each have a rectangular protrusion on the front and rear sides of the left rectangular bar, and the second and third crossbars each have a corresponding elongated guide groove on their front and rear outer walls.
[0010] The guardrail post has two circular holes symmetrically arranged on the inner side. The width of the rectangular groove on the guardrail post is twice the width of the rectangular block at one end of the first and third horizontal bars. In addition, a circular baffle is provided on one side of the rectangular block at one end of the first and third horizontal bars.
[0011] Each of the lower panels has a vertical protrusion at its top, and each of the upper panels has a corresponding groove on its bottom inner side. After assembly, the protrusion at the top of the lower panel will fit tightly into the groove on the bottom inner side of the upper panel.
[0012] This utility model provides a combined fiberglass guardrail for subway use, which has the following beneficial effects: The first, second, and third horizontal bars, along with the lower and upper railings, together constitute the railing of the guardrail. The lower and upper railings are assembled by interlocking. The overall length of the first, second, and third horizontal bars can be reduced and extended, which helps to reduce the lateral space occupied during transportation. Moreover, the guardrail does not require many screws to be used during installation, making the installation process more convenient and labor-saving. Attached Figure Description

[0016] 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, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0017] Example 1: Please refer to Figures 1 to 6 : This utility model proposes a combined fiberglass guardrail for subway use, comprising: guardrail posts 1; each guardrail post 1 has a set of locking rods 2 installed on its inner top side, the guardrail posts 1 being used to support the railing section of the guardrail, and the locking rods 2 being used to lock and fix the railing section of the guardrail; two sets of first horizontal bars 3, second horizontal bars 4, and third horizontal bars 5 are installed between two guardrail posts 1, with the second horizontal bars 4 slidably installed on the left side of the first horizontal bars 3, and the third horizontal bars 5 slidably installed on the left side of the second horizontal bars 4, the first horizontal bars 3, and the second horizontal bars 4... The third crossbar 5 is used to support the lower panel 6 and the upper panel 7. The overall length of the first crossbar 3, the second crossbar 4 and the third crossbar 5 can be contracted and extended to reduce the length space occupied during transportation and to facilitate installation and unfolding. A lower panel 6 is welded to the top of the lower first crossbar 3, the second crossbar 4 and the third crossbar 5, and an upper panel 7 is welded to the bottom of the upper first crossbar 3, the second crossbar 4 and the third crossbar 5. The lower panel 6 and the upper panel 7 can serve as shielding and protection.
[0018] In this embodiment, as Figure 1 and Figure 5 As shown, the guardrail post 1 is provided with two rectangular grooves with front openings. One end of the first horizontal bar 3 and the third horizontal bar 5 is provided with a rectangular block, and the rectangular block can be embedded into the rectangular groove on the guardrail post 1 and fit tightly against the inner wall of the rectangular groove. During installation, the rectangular blocks at one end of the two sets of the first horizontal bar 3 and the third horizontal bar 5 can be pushed into the rectangular groove on the guardrail post 1, so as to initially fix the first horizontal bar 3, the second horizontal bar 4 and the third horizontal bar 5.
[0019] In this embodiment, as Figures 1-4 As shown, a rectangular bar is provided on the left side of both the first crossbar 3 and the second crossbar 4, and a rectangular groove is provided inside the right side of both the second crossbar 4 and the third crossbar 5. The rectangular bars on the left side of the first crossbar 3 and the second crossbar 4 can slide left and right in the rectangular grooves inside the right side of the second crossbar 4 and the third crossbar 5. Therefore, the overall length of the first crossbar 3, the second crossbar 4 and the third crossbar 5 can be contracted and extended, which is convenient to reduce the length space occupied during transportation and is also very convenient to install and unfold.
[0020] In this embodiment, as Figures 1-3 and Figure 5 and Figure 6 As shown, the locking rod 2 has an inverted U-shaped structure, with two round rods at the bottom. The inner side of the guardrail post 1 has two corresponding round holes. The rectangular blocks at one end of the first horizontal bar 3 and the third horizontal bar 5 also have a through-hole. During installation, the rectangular blocks at one end of the two sets of first horizontal bars 3 and third horizontal bars 5 can be pushed into the rectangular grooves on the guardrail post 1, and then the locking rod 2 can be inserted into the round holes on the inner side of the guardrail post 1. During this process, the round rod below the locking rod 2 will also pass through the round holes on the rectangular blocks at one end of the first horizontal bar 3 and the third horizontal bar 5. Therefore, the positions of the two sets of first horizontal bars 3, second horizontal bars 4 and third horizontal bars 5 can be firmly fixed, and the lower guardrail 6 and the upper guardrail 7 can be prevented from separating, thus forming a complete guardrail.
[0021] In this embodiment, as Figures 1-4 As shown, a rectangular protrusion is provided on the front and rear sides of the rectangular rod on the left side of the first crossbar 3 and the second crossbar 4. A corresponding elongated guide groove is also provided on the outer wall of the front and rear sides of the second crossbar 4 and the third crossbar 5. When the rectangular rod on the left side of the first crossbar 3 and the second crossbar 4 slides in the rectangular groove inside the right side of the second crossbar 4 and the third crossbar 5, the rectangular protrusions on the front and rear sides of the rectangular rod will also slide in the elongated guide groove. Moreover, the rectangular protrusions and the elongated guide groove can also play a limiting role to prevent the adjacent first crossbar 3, second crossbar 4 and third crossbar 5 from separating.
[0022] In this embodiment, as Figures 1-3 As shown, each of the lower panel 6 has a vertical protrusion at its top, and each of the upper panel 7 has a corresponding groove on its bottom inner side. After assembly, the protrusion at the top of the lower panel 6 will fit tightly into the groove on the bottom inner side of the upper panel 7. During installation, the lower panel 6 and the upper panel 7 can be aligned vertically, and the protrusion at the top of the lower panel 6 can be inserted into the groove on the bottom inner side of the upper panel 7, thereby locking the lower panel 6 and the upper panel 7 in the horizontal direction.
[0023] Example 2, based on Example 1, such as Figures 1-6As shown, the two round holes on the inner side of the guardrail post 1 are symmetrically arranged. The width of the rectangular groove on the guardrail post 1 is twice the width of the rectangular block at one end of the first horizontal bar 3 and the third horizontal bar 5. Moreover, a circular baffle is provided on one side of the rectangular block at one end of the first horizontal bar 3 and the third horizontal bar 5. During installation, the rectangular blocks at one end of the two sets of the first horizontal bar 3 and the third horizontal bar 5 can be pushed into the rectangular groove on the guardrail post 1. At this time, the circular baffle on one side of the rectangular block at one end of the first horizontal bar 3 and the third horizontal bar 5 can play the role of limiting and assisting in positioning. Furthermore, guardrails can be installed on both the left and right sides of the guardrail post 1.
[0024] The working principle of this embodiment is as follows: When transporting this guardrail, the guardrail post 1 and locking rod 2 can be placed separately, while the lower guardrail plate 6 and upper guardrail plate 7 can be separated into upper and lower parts. At the same time, the second horizontal bar 4 and the third horizontal bar 5 can be pushed to the right. During this process, the rectangular bars on the left side of the first horizontal bar 3 and the second horizontal bar 4 will slide in the rectangular grooves inside the right side of the second horizontal bar 4 and the third horizontal bar 5. Ultimately, the overall length of the first horizontal bar 3, the second horizontal bar 4, and the third horizontal bar 5 can be shortened, thereby reducing the length space occupied during transportation. When installing this device, firstly, the two sets of first horizontal bars 3, second horizontal bars 4, and third horizontal bars 5 are stretched as a whole, and then the guardrail post 1 is adjusted according to the overall length of the first horizontal bars 3, second horizontal bars 4, and third horizontal bars 5. The lower guardrail 6 and the upper guardrail 7 are fixed to the edge of the subway platform with expansion screws at intervals. Then, the lower guardrail 6 and the upper guardrail 7 are joined together vertically, and the protruding plate at the top of the lower guardrail 6 is inserted into the groove on the inner side of the bottom of the upper guardrail 7. This locks the lower guardrail 6 and the upper guardrail 7 horizontally. Then, the rectangular blocks at one end of the two sets of first horizontal bars 3 and third horizontal bars 5 are pushed into the rectangular grooves on the guardrail post 1. Then, the locking rod 2 is inserted into the round hole on the inner side of the guardrail post 1. During this process, the round rod below the locking rod 2 will also pass through the round hole on the rectangular block at one end of the first horizontal bar 3 and the third horizontal bar 5. Therefore, the positions of the two sets of first horizontal bars 3, second horizontal bars 4 and third horizontal bars 5 can be firmly fixed, and the lower guardrail 6 and the upper guardrail 7 can be prevented from separating, thus forming a complete guardrail.
[0025] The following points should be noted in this article: 1. The accompanying drawings of this embodiment only involve the structures involved in this embodiment; other structures can refer to the general design.
[0026] 2. Where there is no conflict, this embodiment and the features in the embodiment can be combined with each other to obtain new embodiments.
