Description

Technical Field

[0001] This utility model belongs to the field of guardrail technology, specifically relating to a guardrail that is easy to assemble. Background Technology

[0002] In various locations, such as construction sites, public areas, and residential communities, guardrails play an indispensable role as key facilities for ensuring safety and delineating areas. At construction sites, guardrails effectively isolate the construction area from the outside world, preventing unauthorized personnel from entering, avoiding accidents, and ensuring the smooth progress of construction and the safety of personnel. In public areas, such as parks and squares, guardrails guide pedestrian flow, regulate people's behavior, and protect some scenic areas. In residential communities, guardrails not only enhance the security of the community and prevent unauthorized entry, but also create a relatively independent and private living space for residents.

[0003] However, most existing guardrails, during the assembly process, as described in the appendix of this application... Figure 3 As shown (attached) Figure 3 The existing method of assembling and fixing guardrails requires first fixing four mounting sleeves (connecting accessories) with mounting holes to the guardrail bracket, and then fixing the mesh panel inside the mounting hole on one side of the mounting sleeve with bolts. This not only easily causes the mounting sleeves (connecting accessories) to scratch and wear the surface of the bracket, but also exposes the bolts at the connection, resulting in an unsightly overall guardrail. At the same time, this method of installing connecting accessories makes the guardrail assembly process relatively troublesome and inconvenient for workers to operate. Therefore, we propose a guardrail that is easy to assemble. Utility Model Content

[0004] The purpose of this utility model is to provide a guardrail that is easy to assemble, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a guardrail that is easy to assemble, comprising two supports, each of the two supports having a rain cap on its top, a mesh plate between the two supports, each support having two symmetrical connecting holes inside, each connecting hole having a pre-set threaded sleeve inside, and the mesh plate having fixing holes on both sides of its inner cavity corresponding to the four connecting holes, each fixing hole having a fixing bolt threadedly connected to the pre-set threaded sleeve inside.

[0006] In a preferred embodiment, each of the brackets has a support on both sides of its bottom, the support has an installation hole inside, and each of the supports has a triangular inclined plate fixedly connected to the bracket on both sides of its top.

[0007] In a preferred embodiment, each of the supports is fitted with a support cover, and the top of the support cover is provided with triangular grooves on both sides that are adapted to the inclined plate.

[0008] In a preferred embodiment, a welding frame is provided on the inner wall of the mesh panel, and a guardrail mesh is welded onto the welding frame.

[0009] In a preferred embodiment, the thickness of the welding frame is greater than the thickness of the hexagonal head of the fixing bolt.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This easy-to-assemble guardrail features symmetrical connecting holes inside the support frame, with pre-installed threaded sleeves within these holes. Corresponding fixing holes are located on both sides of the inner cavity of the mesh panel. These, combined with fixing bolts, enable quick connection between the mesh panel and the support frame. This built-in connector design not only reduces the number of connectors required but also prevents them from scratching or abrading the support frame surface. Furthermore, the bolts at the connection points are not exposed, eliminating color differences between the support frame and the mesh panel caused by external connectors, thus improving the overall aesthetics of the guardrail.

[0012] Meanwhile, workers only need to screw the fixing bolts into the preset threaded sleeves to easily complete the assembly between the mesh panel and the bracket, making the fence assembly process simpler and more convenient, greatly simplifying the assembly process, significantly improving assembly efficiency, and thus effectively saving manpower and time costs.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0019] Example 1

[0020] Please see Figures 1-3 This utility model provides a guardrail that is easy to assemble, including two brackets 1, each of which is provided with a rain cap 3 on its top. A mesh plate 2 is provided between the two brackets 1. Each bracket 1 has two symmetrical connecting holes 101 inside, and each connecting hole 101 has a pre-set threaded sleeve 4 inside. The inner sides of the mesh plate 2 have fixing holes 201 corresponding to the four connecting holes 101. Each fixing hole 201 has a fixing bolt 5 that is threadedly connected to the pre-set threaded sleeve 4 inside. A welding frame 202 is provided on the inner wall of the mesh plate 2. A guardrail mesh 203 is welded on the welding frame 202. The thickness of the welding frame 202 is greater than the thickness of the hexagonal head of the fixing bolt 5.

[0021] In this embodiment, all the necessary components are prepared first, including two brackets 1, one mesh plate 2, two rain caps 3, four pre-installed screw sleeves 4 (pre-installed in the connection holes 101 of the brackets 1), and four fixing bolts 5;

[0022] Place the two brackets 1 in the predetermined installation position, ensuring that the two brackets 1 are parallel and the spacing is appropriate. This spacing should match the width of the mesh panel 2 so that the mesh panel 2 can be installed accurately later. Then, put the two rain caps 3 on the top of the two brackets 1 respectively, and press them gently to make them securely installed on the brackets 1. The purpose of the rain caps 3 is to prevent rainwater and other liquids from entering the interior of the brackets 1, avoiding corrosion and damage to the brackets 1, and extending the service life of the brackets 1.

[0023] Place the mesh plate 2 between the two supports 1 so that the fixing holes 201 on both sides of the inner cavity of the mesh plate 2 correspond one-to-one with the connecting holes 101 on the support 1. At this time, since the thickness of the welding frame 202 is greater than the thickness of the hexagonal head of the fixing bolt 5, the hexagonal head of the fixing bolt 5 will not protrude from the surface of the welding frame 202 during the installation process, ensuring the flatness of the surface of the mesh plate 2, and also preventing the hexagonal head of the fixing bolt 5 from scratching or colliding with other objects.

[0024] From the outside of the mesh plate 2, pass the fixing bolts 5 through the fixing holes 201 in sequence and screw them into the preset screw sleeves 4. Use a suitable tool (such as a wrench) to tighten the fixing bolts 5 to ensure that the connection between the mesh plate 2 and the bracket 1 is firm and there is no looseness. In the same way, install and tighten all four fixing bolts 5 to complete the assembly of the mesh plate 2 and the two brackets 1.

[0025] In the above scheme, it should be noted that: by pre-setting a pre-set screw sleeve 4 inside the bracket 1 and opening a corresponding fixing hole 201 on the mesh plate 2, and using fixing bolts 5 to connect the mesh plate 2 and the bracket 1, this design of built-in connecting accessories not only reduces the number of original connecting accessories, but also prevents the connecting accessories from scratching and wearing the surface of the bracket 1. At the same time, the fixing bolts 5 at the connection point are not exposed, so that there is no color difference problem between the bracket 1 and the mesh plate 2 caused by external connecting accessories, thereby improving the overall aesthetics of the guardrail.

[0026] Please see Figure 1 Each support 1 has a support 102 on both sides of its bottom. The support 102 has an installation hole inside. Each support 102 has a triangular inclined plate 1021 fixedly connected to the support 1 on both sides of its top. Each support 102 has a support cover 6 on its outside. The support cover 6 has a triangular inclined groove on both sides of its top that matches the inclined plate 1021.

[0027] Place the support 102 in the predetermined installation position, aligning the mounting holes inside the support 102 with the pre-drilled holes on the ground. Secure the support 102 to the ground by passing bolts through the mounting holes. Slowly slide the support cover 6 onto the support 102 from one side, ensuring that the support cover 6 completely covers the support 102. During the installation process, ensure that the triangular grooves on both sides of the top of the support cover 6 correspond to the positions of the inclined plate 1021, and ensure that the grooves can be accurately embedded around the inclined plate 1021, so that the support cover 6 is installed in place.

[0028] The support cover 6 provides a comprehensive protection for the support 102. During daily use, the support 102 is easily corroded by the external environment, such as rainwater, dust, and corrosive gases. The support cover 6 can block the intrusion of these harmful substances, prevent the support 102 from rusting and corroding, and extend the service life of the support 102. At the same time, the support cover 6 can also prevent the support 102 from being directly damaged when it is subjected to external impact, reducing the cost of maintenance and replacement.

[0029] Example 2

[0030] Please see Figure 2 The difference between this embodiment and the first embodiment is that: the surface of the bracket 1 can also be provided with connection holes 101 at other positions, and the subsequently provided connection holes 101 are offset and perpendicular to the original connection holes 101. In this way, the bracket 1 can install another mesh plate 2 that is perpendicular to the original mesh plate 2 through the connection holes 101 at different positions.

[0031] When it is necessary to install the guardrail at a right angle, multiple connection holes 101 can be opened on the surface of the bracket 1 at the right angle. That is, two kinds of staggered vertical connection holes 101 can be opened on the front and side of the bracket 1 respectively. Then, the preset screw sleeve 4 is placed inside the two kinds of connection holes 101 in different directions, and the mesh plate 2 is fixed by the fixing bolt 5. In this way, two mutually perpendicular mesh plates 2 can be installed on one bracket 1.

[0032] Since there is no need for complex customization or splicing operations at right angles, installation can be completed simply by using the existing bracket 1 and mesh panel 2, and by simple alignment and bolt fixing. This greatly simplifies the installation process, and operators can quickly complete the installation of the guardrail by following the simple assembly process, saving installation time and labor costs.

[0033] The working principle and usage process of this utility model are as follows: First, prepare two brackets 1, one mesh plate 2, two rain caps 3, four pre-set screw sleeves 4 (pre-installed in the connection hole 101 of bracket 1), four fixing bolts 5, support 102, support cover 6, and bolts required for installing support 102.

[0034] Next, place the two brackets 1 in parallel at the predetermined position, with the spacing matching the width of the mesh plate 2. Put the two rain caps 3 on the top of the brackets 1 respectively and press them firmly to prevent rainwater from entering the interior of the brackets 1. Then place the mesh plate 2 between the two brackets 1, so that the fixing holes 201 on both sides of the inner cavity of the mesh plate 2 correspond one-to-one with the connecting holes 101 of the brackets 1. Then, screw the fixing bolts 5 through the fixing holes 201 from the outside of the mesh plate 2 into the preset screw sleeves 4 and tighten them with a wrench. Install and tighten all four fixing bolts 5 to complete the assembly of the mesh plate 2 and the brackets 1.

[0035] Finally, place the support 102 in the predetermined position, aligning its internal mounting holes with the pre-drilled holes in the ground. Use bolts to pass through the mounting holes and fix the support 102 to the ground. Slowly slide the support cover 6 onto one side of the support 102, ensuring that the triangular grooves on both sides of the top of the support cover 6 correspond to the positions of the inclined plate 1021 and are embedded around it, so that the support cover 6 is installed in place, thereby easily achieving the assembly and fixation of the guardrail.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
