[0002] The PVC guardrail fixing frame is a supporting structure used to fix the PVC guardrail. Its main function is to provide support and stability, ensure that the PVC guardrail is installed firmly, prevent it from tilting or collapsing, and ensure the service life and safety of the guardrail.

[0003] According to a PVC guardrail fixing frame provided by patent application number CN202223154930.1, a guardrail plug-in frame is formed by a ground anchor seat, a vertical plate, an anti-slip seat, a reset spring, a rotating plate and an anti-slip pad on the rotating plate. The PVC guardrail and the guardrail plug-in frame form a PVC guardrail fixing frame. The utility model PVC guardrail fixing frame is novel in design and can be used for lawn enclosure to meet the requirements of neatness, beauty, easy installation, firmness and durability, and has high adaptability and reuse rate. It is an ideal lawn enclosure guardrail equipment.

[0004] The disadvantages of the above-mentioned fixing frame are that: during the use of the fixing frame, each PVC guardrail fixing frame is protected separately, and the PVC guardrail fixing frames cannot be connected end to end. Therefore, when the guardrail is slightly collided or even when the wind force is strong, it will topple over, so the protection effect is poor. During the use of the fixing frame, the connection between the PVC guardrail and the guardrail plug-in frame is clamped by the friction of the anti-slip seat and the anti-slip pad. People and small animals can easily touch the soft rope and the operating plate, which causes the rotating plate to rotate, and then causes the PVC guardrail to fall off, so the fixing effect is poor.

[0020] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0021] See also Figure 1-3 According to an embodiment of the utility model, a PVC guardrail fixing frame includes a support column 1, a fixing mechanism 2 is installed on the support column 1, a connecting column 3 is fixedly installed on the top of the support column 1, the support column 1 and the connecting column 3 form a guardrail rack, vertical rotation grooves 4 are opened around the connecting column 3, the rotation grooves 4 are rotatably connected to the PVC guardrail board 5, and connecting mechanisms 6 are installed on the bottom of both sides of the PVC guardrail board 5. The PVC guardrail board 5 is installed between a pair of guardrail racks to form a PVC guardrail fixing frame.

[0022] The PVC guardrail board 5 is connected to the guardrail inserting frames at the head and tail of the PVC guardrail fixing frame in sequence to form a whole guardrail.

[0023] In this embodiment, the fixing mechanism 2 includes a mounting plate 7 fixedly mounted around the bottom of the support column 1. The mounting plate 7 has threaded holes near the four corners. A blind hole is opened at the center of the bottom of the support column 1 and is slidably connected to an anchor rod 8.

[0024] The mounting plate 7 can be fixed on the hard ground by installing bolts through threaded holes, and the anchor rod 8 can be inserted into the soft ground for fixing.

[0025] In this embodiment, a slide groove 9 is opened on the side of the support column 1 and connected to the blind hole inside it. Blocks 10 are fixedly installed on the slide groove 9 at equal intervals. A moving block 11 is slidably connected to the slide groove 9, and the end of the moving block 11 is fixedly connected to the side wall of the anchor rod 8.

[0026] The manually movable block 11 slides on the slide groove 9 , so that the anchor rod 8 can be retracted and released, and the function of the stopper 10 is to limit the movable block 11 .

[0027] In this embodiment, the connecting mechanism 6 includes a first installation cavity 12 opened in the bottom of the PVC guardrail 5, and a thick connecting rod 13 is slidably connected in the first installation cavity 12. The side wall of the PVC guardrail 5 located in the first installation cavity 12 is penetrated by a movable groove 14, and a paddle 15 is fixedly installed on the two side walls of the thick connecting rod 13. One end of the paddle 15 passes through the movable groove 14, and a first spring 16 is fixedly connected between the paddle 15 and the bottom of the first installation cavity 12.

[0028] Manually pressing the paddle 15 can drive the coarse connecting rod 13 to move downward. The movable groove 14 serves to limit the paddle 15 . The first spring 16 serves to reset the paddle 15 and the coarse connecting rod 13 .

[0029] In this embodiment, a thin connecting rod 17 is fixedly installed below the thick connecting rod 13, and a first cone block 18 with a pointed end facing downward is fixedly installed at the end of the thin connecting rod 17. The thin connecting rod 17 passes through and is slidably connected to a second cone block 19 with a pointed end facing upward. The diameter of the first cone block 18 is smaller than that of the second cone block 19. A second spring 20 is fixedly connected between the first cone block 18 and the second cone block 19 and wraps the thin connecting rod 17.

[0030] Among them, the function of the second spring 20 is to prevent the first cone block 18 and the second cone block 19 from forming a fitting state, and the function of the second cone block 19 is to squeeze the locking block 23 into the blind hole on the side wall of the connecting hole 21, so as to unlock the first cone block 18 and enable the first cone block 18 to be detached from the connecting hole 21.

[0031] In this embodiment, a connecting hole 21 is opened at the top of the support column 1 and located at the axis of the rotating groove 4, blind holes are opened on the side walls at both ends of the connecting hole 21 and a third spring 22 is fixedly connected to the bottom thereof, and the end of the third spring 22 is fixedly connected to a locking block 23, and the locking block 23 can engage with the first cone block 18.

[0032] The third spring 22 resets the locking block 23 and ensures that the locking block 23 always locks the first cone block 18 .

[0033] In specific applications, when installing the guardrail on a hard ground, it is necessary to drill holes in the ground, and then connect the bolts and fix them through the threaded holes on the mounting plate 7. When installing the guardrail on a soft ground, manually slide the moving block 11 downward along the slide groove 9 to bring the anchor rod 8 out from the bottom of the support column 1, and then clamp the moving block 11 between the stoppers 10. Thereafter, insert the anchor rod 8 into the soft ground to fix it, and then insert the two ends of the PVC guardrail 5 into the rotating groove 4 on the connecting column 3 of the guardrail bracket on both sides respectively, and the thin connecting rod 17 at the bottom of the PVC guardrail 5 will be inserted into the connecting hole 21. Press the PVC guardrail 5 hard. At this time, the first cone block 18 passes over the locking block 23, so that the two are locked together. When the guardrail needs to be disassembled, manually press The pressing paddle 15 can drive the coarse connecting rod 13 to move downward. At this time, the coarse connecting rod 13 will squeeze the locking block 23 with the second cone block 19. When the second cone block 19 passes the locking block 23, you can let go. At this time, the first spring 16 will reset the paddle 15 upward, and at the same time, it will also drive the coarse connecting rod 13 to move upward. The upward movement of the coarse connecting rod 13 will also drive the thin connecting rod 17 to move upward. The upward movement of the thin connecting rod 17 will drive the first cone block 18 to move upward. After continuous upward movement, the first cone block 18 is close to the second cone block 19. At this time, the second cone block 19 moves up again to squeeze the locking block 23 away. Since the first cone block 18 and the second cone block 19 are relatively close and the diameter of the first cone block 18 is smaller than that of the second cone block 19, the first cone block 18 will also disengage from the engaging locking block 23, thereby achieving disconnection.
