Detailed Embodiment

[0022] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the drawings. Only the preferred embodiments in the description are taken as examples. All other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.

[0023] As Figures 1-4As shown in the figure, the present specific embodiment adopts the following technical solution: It includes a vertical rod 1, a sleeve 2 and a cross rod 3. The upper and lower sides between multiple vertical rods 1 are both suspended with sleeves 2. Two cross rods 3 are movably inserted into the sleeves 2. Slots 11 that cooperate with one end of the cross rod 3 are opened on the left and right side walls of the vertical rod 1. Chamfers 17 are provided at the openings of the slots 11. Through the chamfers 17, the openings of the slots 11 can be enlarged, making it more conducive to inserting the end of the cross rod 3 into the slots 11. Reflective strips 18 are adhesively and fixedly arranged on the front and rear side walls of the vertical rod 1. The reflective strips 18 can reflect the surrounding light at night, making the guardrail more eye-catching at night and realizing the warning to personnel.

[0024] It further includes:

[0025] Rotating shafts 4. There are two rotating shafts 4, which are respectively rotatably connected to the two sleeves 2 through bearings. Gears 5 are fixedly sleeved on the rotating shafts 4. Rack bars 6 are meshed and arranged on the front and rear sides of the gears 5. An adjusting and limiting mechanism 7 is provided on the rotating shafts 4.

[0026] Sliding strips 8. There are four sliding strips 8, which are respectively fixedly arranged on the four rack bars 6 through bolts. The sliding strips 8 are fixedly connected to one side of the cross rod 3 through bolts, and the sliding strips 8 are slidably arranged in the moving slots 12 opened on the other side of the cross rod 3.

[0027] Internal thread cylinders 9. There are four internal thread cylinders 9, which are all suspended between the two vertical rods 1. The internal thread directions of the upper and lower sections of the internal thread cylinders 9 are set in opposite directions. Two threaded rods 10 are rotatably inserted into the internal thread cylinders 9 through threads. Positioning slots 13 that cooperate with the threaded rods 10 are opened on the side walls of the cross rod 3 and the sleeves 2. A guide rod 15 is fixedly arranged at the upper end of the lower threaded rod 10 through a bolt. The guide rod 15 is movably inserted into the upper threaded rod 10. A plurality of positioning blocks 16 are equally angularly distributed on the outer ring wall of the threaded rod 10. The positioning blocks 16 are abutted and arranged in the positioning slots 13. Through the positioning blocks 16, the limit of the end of the threaded rod 10 in the positioning slots 13 can be realized. With the cooperation of the guide rod 15, after inserting the lower end of the lower threaded rod 10 into the positioning slots 13, the distance between the upper and lower threaded rods 10 can be adjusted by rotating the internal thread cylinder 9 with one hand, making the installation process of the guardrail more convenient.

[0028] The adjusting and limiting mechanism 7 includes:

[0029] Adjusting rods 7-1. The adjusting rods 7-1 are movably inserted into the rotating shafts 4. Springs 7-2 connected to the adjusting rods 7-1 are fixedly arranged in the rotating shafts 4.

[0030] The adjusting handle 7-3 is movably arranged at the lower part of the sleeve 2. The lower end of the adjusting rod 7-1 passes through the rotating shaft 4 and is connected to the adjusting handle 7-3. Limit blocks 7-4 are fixedly arranged on the upper left and right sides of the adjusting handle 7-3 through bolts. A plurality of limit grooves 14 matched with the limit blocks 7-4 are equally angled and opened on the lower side wall of the sleeve 2.

[0031] When using the utility model, a plurality of vertical rods 1 are fixed on the ground, and then the adjusting handle 7-3 is moved downward. The adjusting handle 7-3 drives the adjusting rod 7-1 and the limit block 7-4 to move downward and stretch the spring 7-2. At this time, the limit block 7-4 disengages from the limit groove 14, and then the adjusting handle 7-3 can be rotated. The adjusting handle 7-3 drives the rotating shaft 4 to rotate through the adjusting rod 7-1. The rotating shaft 4 drives the gear 5 to rotate. The gear 5 drives the sliding strips 8 on the front and rear sides to move synchronously and reversely through the rack 6, so that the cross bars 3 on the left and right sides can also move synchronously and reversely until the end parts of the cross bars 3 on the left and right sides are respectively inserted into the slots 11 of the vertical rods 1 on both sides. Then the adjusting handle 7-3 can be released, so that the spring 7-2 resets and shortens. The spring 7-2 drives the adjusting rod 7-1 to move upward. The adjusting rod 7-1 drives the adjusting handle 7-3 to move upward, so that the limit block 7-4 is clamped into the corresponding limit groove 14. Then the end part of the lower threaded rod 10 is inserted into the lower positioning groove 13, and then the internal thread cylinder 9 can be rotated. Through the guiding action of the guiding rod 15, the distance between the upper and lower threaded rods 10 can be adjusted until the upper threaded rod 10 is inserted into the upper positioning groove 13 to complete the assembly of the guardrail.

[0032] After adopting the above structure, the beneficial effects of the specific embodiment are as follows:

[0033] 1. Through the cooperation of the rotating shaft 4, the gear 5, the rack 6, the sliding strip 8 and the internal thread cylinder 9, not only the disassembly and assembly process is relatively convenient, which is conducive to replacing damaged cross bars 3, threaded rods 10, etc., but also it is convenient to adjust according to the size of the garden specifications;

[0034] 2. By adjusting the limiting mechanism 7, the rotation of the rotating shaft 4 can be restricted to prevent the rotating shaft 4 from being easily rotated due to misoperation.

[0035] For those skilled in the art, they can modify the technical solutions recorded in the foregoing embodiments and perform equivalent replacements of some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
