[0002] As the name implies, wood-plastic guardrails and handrails are made of wood-plastic materials. This material has both the weather resistance and corrosion resistance of plastic and the texture and touch of wood, so it has excellent durability and aesthetics in outdoor environments. The safety performance of wood-plastic guardrails is excellent. Its sturdy and durable characteristics can effectively prevent injuries caused by accidental falls and provide residents with a safe travel environment. At the same time, its design is flexible and can be customized according to different scenarios and needs to meet the safety needs of different places. Wood-plastic guardrails are also environmentally friendly. Compared with traditional metal or wooden guardrails, wood-plastic materials have less impact on the environment during production and use. Its recyclability also reduces the waste of resources, which is in line with today's society's pursuit of green and low-carbon life.

[0003] In the prior art, when the plastic wood handrail corners are connected to each other, in order to reduce the loss of plastic wood, connecting parts are generally used for connection, such as bolt connection or mortise and tenon connection. This installation method has a stable connection but the process is cumbersome. In some cases, hot melt connection is used. This connection method is more stable than glue and has less loss than bolt connection. Although this method is used more frequently, it has high technical requirements for the staff. At the same time, it takes a certain amount of time to calculate the area and thickness of the hot melt part, which takes a certain amount of time during installation, thereby affecting the efficiency of installation.

DETAILED DESCRIPTION

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings. Example

[0022] Reference Figure 1-Figure 4 The utility model discloses a connector for the corner of a plastic wood guardrail handrail, comprising two corner rods 1, arc grooves 2 are provided on opposite sides of the two corner rods 1, circular holes 3 are provided on the sides away from each other in the two arc grooves 2, and the inner ends of the circular holes 3 are fixedly connected with return springs 4, and the ends of the return springs 4 are fixedly connected with limit blocks 5, and the upper and lower sides of the limit blocks 5 away from the return spring 4 are both arc-shaped, and locking pieces 6 are provided in the two arc grooves 2, and a driving piece 7 is provided between the two corner rods 1.

[0023] In this embodiment, during use, as the guardrail handrail is laid, the two straight handrails will be butted at the corner, so they need to be connected through the corner rod 1, and the locking piece 6 is embedded in the arc groove 2 of the two corner rods 1, and then the limit block 5 in the circular hole 3 will be squeezed and then reset. The locking piece 6 is preliminarily positioned by the limit block 5, and then the driving piece 7 is inserted between the two corner rods 1, thereby driving the locking piece 6 to lock the two corner rods 1, and at the same time eliminating the gap between the two corner rods 1, thereby improving the installation efficiency without affecting the appearance.

[0024] In a further preferred embodiment of the present invention, Figure 2-4 As shown, the locking member 6 includes a positioning column 8, and both ends of the positioning column 8 are provided with a slide groove 9. The positioning column 8 is slidably connected to the corresponding limit block 5 through the slide groove 9, and arc blocks 10 are fixedly connected on the upper and lower sides of the limit block 5 in the slide groove 9.

[0025] In this embodiment, the slide groove 9 is set so that the limit block 5 can be inserted when the positioning column 8 slides into the arc groove 2, and then when passing through the arc block 10, it will push the limit block 5 and compress the return spring 4, and then the limit block 5 will be embedded between the two arc blocks 10. At this time, the rotation of the positioning column 8 can be avoided, completing the preliminary positioning of the positioning column 8.

[0026] In a further preferred embodiment of the present invention, Figure 2-4 As shown, a gear rod 11 is rotatably installed in the positioning column 8 with the axis as the reference, and tooth plates 12 are slidably connected at both ends of the positioning column 8, located on the upper and lower sides of the gear rod 11, and the ends of the tooth plates 12 are respectively inserted into the corresponding corner rods 1, and the tooth plates 12 are meshed with the gear rod 11.

[0027] In this embodiment, the gear rod 11 is driven by the driving member 7 to rotate, thereby driving the gear rod 11 to rotate and driving the tooth plate 12 to move. Then, the four tooth plates 12 will be inserted into the corresponding corner rods 1 respectively during movement. At this time, the positioning of the two corner rods 1 is completed, thereby achieving the effect of quickly locking and connecting the two corner rods 1.

[0028] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the driving member 7 includes a notch 13 , which is opened in the middle of the positioning column 8 , and an outer gear sleeve 14 is rotatably installed in the notch 13 , and the inner peripheral wall of the outer gear sleeve 14 is fixedly connected to the gear rod 11 .

[0029] In this embodiment, the provided groove 13 facilitates the installation of the external gear sleeve 14. The rotation of the external gear sleeve 14 can drive the rotation of the gear rod 11, and then the rotation of the gear rod 11 drives the tooth plates 12 located at both ends of the positioning column 8 to move, so that the ends of the tooth plates 12 are inserted into the corresponding corner rods 1, completing the positioning of the two corner rods 1.

[0030] In a further preferred embodiment of the present invention, Figure 1-4 As shown, a sleeve plate 15 is slidably connected between the two corner rods 1 , and a rack 16 is fixedly connected to the inner side of the sleeve plate 15 , and the rack 16 is meshed with the outer gear sleeve 14 .

[0031] In this embodiment, the set plate 15 can be used to close the gap between the two corner rods 1, and at the same time can drive the rack 16 to move downward. The downward movement of the rack 16 will drive the outer gear sleeve 14 to rotate. When the outer gear sleeve 14 rotates, it will drive the gear rod 11 to rotate. The rotation of the gear rod 11 will drive the corresponding tooth plate 12 to move, so that the tooth plate 12 is inserted into the corresponding corner rod 1, so that the two corner rods 1 are positioned and connected. When disassembling, you only need to pull the set plate 15 upward. When pulling it out, the outer gear sleeve 14 is driven to rotate by the rack 16, and then the gear rod 11 is driven to rotate, and then the tooth plate 12 is retracted into the positioning column 8, thereby achieving the effect of quick disassembly.

[0032] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
