AI Technical Summary
Most existing temporary fencing is a fixed, one-piece structure that cannot be flexibly adjusted in length. This makes it difficult to adapt effectively when the area being covered is large, especially when there are buildings or other objects on one side of the area being covered, which affects the effectiveness of the fencing.
A temporary enclosure structure including a first support rod and a second support rod was designed. The length of the enclosure can be adjusted by combining a sliding groove, a guide groove, a support plate and a rotating plate, and the stability can be increased by a vertical plate and a folded plate.
The length of the fence can be flexibly adjusted, which improves its adaptability to different construction sites and enhances its stability and protective effect.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-6 As shown, a temporary enclosure with adjustable length includes a first support rod 1 and a second support rod 3. A first enclosure 2 is fixedly connected to the right side of the first support rod 1, and a second enclosure 4 is fixedly connected to the left side of the second support rod 3. A sliding groove 7 is provided on the top of the surface of the second enclosure 4, and a guide groove 17 is provided on the bottom of the back of the second enclosure 4. A concave plate 5 is fixedly connected to the top of the first enclosure 2, and a sliding plate 6 is fixedly connected to the other end of the concave plate 5. The other end of the sliding plate 6 is slidably connected to the inside of the sliding groove 7. A guide plate 18 is fixedly connected to the surface of the first enclosure 2, and the guide plate 18 is slidably connected to the inside of the guide groove 17. Movable grooves 8 are provided on both the front and rear sides of the first support rod 1 and the second support rod 3. A support plate 9 is rotatably connected inside the movable groove 8. A through groove 10 is provided through the surface of the support plate 9. Folded plates 11 are fixedly connected to both the front and rear sides of the first support rod 1 and the second support rod 3, and the top of the folded plate 11 extends into the inside of the through groove 10 and is rotatably connected to a rotating plate 12.
[0022] The top of the second enclosure 4 is provided with several positioning holes 13, and the top of the concave plate 5 is provided with a positioning pin 14. The other end of the positioning pin 14 is inserted into the interior of the positioning hole 13. Through the positioning hole 13 and the positioning pin 14, after the second support rod 3 and the second enclosure 4 move inside the concave plate 5, the positioning pin 14 can be inserted into the interior of the positioning hole 13, thereby fixing the moved second enclosure 4 and the first enclosure 2.
[0023] Vertical plates 15 are rotatably connected to both the front and rear sides of the first support rod 1 and the second support rod 3. The back of the vertical plate 15 is in contact with one side of the stored support plate 9. The vertical plate 15 allows the support plate 9 to be stored in the movable slot 8 after use, thus fixing the support plate 9 in the movable slot 8 and fixing the rotated support plate 9.
[0024] Both sides of the inside of the guide plate 18 and both sides of the inside of the slide plate 6 are embedded with ball bearings 16, and the ball bearings 16 are rolledly connected to the inner walls of the slide groove 7 and the guide groove 17 respectively. By setting the ball bearings 16, the rolling of the ball bearings 16 reduces a certain amount of friction when the guide plate 18 and the slide plate 6 move, thereby making the guide plate 18 and the slide plate 6 move more conveniently.
[0025] The top of the support plate 9 has a through groove 19, which is located below the through groove 10. The groove 19 allows the support plate 9 to be taken out more easily when it is stored in the movable groove 8.
[0026] Warning strips 20 are provided at the bottom of both the front and rear sides of the first enclosure 2 and the second enclosure 4. The warning strips 20 are arranged at equal intervals. The warning strips 20 can more effectively remind people of the danger and prevent it in advance.
[0027] Working principle: When using temporary fencing as a temporary barrier, the temporary fencing can be placed at the designated protection position. If the area to be protected is large, the first support rod 1 and the second support rod 3 can be placed within the protected area. Then, the positioning pin 14 can be pulled upwards to separate it from the positioning hole 13. This will cause the second support rod 3 and the second fencing 4 to move outwards, thereby adjusting the length between the first fencing 2 and the second fencing 4. After adjustment, the positioning pin 14 can be re-inserted through the concave plate 5 and into the positioning hole at the top of the second fencing 4. In the hole 13, the first enclosure 2 and the second enclosure 4 are limited and fixed. In order to improve the stability of the first support rod 1 and the second support rod 3 when they are placed, the vertical plates 15 on the front and rear sides of the first support rod 1 and the second support rod 3 can be rotated, and then the limitation on the support plate 9 is removed, so that one end of the support plate 9 is flipped to the ground surface. Then, one end of the folded plate 11 is inserted into the through groove 10 at the support plate 9. Then, the rotating plate 12 can be rotated to limit the flipped support plate 9, thereby improving the stability of the first enclosure 2 and the second enclosure 4 when they are supported.
