[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0022] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0023] like Figure 1 As shown, the utility model provides a retractable enclosure, comprising:

[0024] The first baffle 1 is vertically fixed on the parapet where the enclosure needs to be erected;

[0025] A second baffle 2 is stacked in front of the first baffle 1, and one side end of the second baffle 2 exceeds the side end of the first baffle 1 close to the end point of the parapet;

[0026] Among them, a sleeve 3 is horizontally arranged on the back side of the first baffle 1 along its own length direction, a connecting rod 4 is vertically arranged on the back side of one side end of the second enclosure, and a cross bar 5 is horizontally arranged on the connecting rod 4 along the length direction of the first baffle 1. The cross bar 5 passes through the sleeve 3 and is slidably connected with the sleeve 3.

[0027] Specifically, the first baffle plate 1 includes an upper steel plate mesh 101 and a lower skirting board 102 , and the second baffle plate 2 has the same structure as the first baffle plate 1 .

[0028] Specifically, the sizes of the first baffle plate 1 and the second baffle plate 2 are substantially the same.

[0029] The sleeve 3 can be made of a steel pipe with an outer diameter of 48 mm and a wall thickness of 5 mm, and the connecting rod 4 and the cross bar 5 can be made of a steel pipe with an outer diameter of 30 mm.

[0030] When the above embodiment is used, the bottom of the first baffle plate 1 is first fixed to the parapet, and then the second baffle plate 2 is pulled so that its side end contacts the structural wall to achieve full enclosure, and then the second baffle plate 2 is bolted to the first baffle plate 1 to fix the second baffle plate 2.

[0031] In the above embodiment, the first baffle 1 and the second baffle 2 are slidably connected through simple components such as a sleeve 3, a connecting rod 4, and a cross bar 5. The second baffle 2 is pulled according to the distance between the first baffle 1 and the end point of the parapet (the structural wall), so that the second baffle 2 is blocked between the first baffle 1 and the structural wall. There is no need to cut the second baffle 2, and the enclosure requirements can be flexibly met.

[0032] Since in the previous embodiment, the second baffle 2 is the same size as the first baffle 1, the lower end of the second baffle 2 may touch the top of the parapet during movement and generate friction, which not only hinders the movement of the second baffle 2 and generates noise, but also wears the skirting board of the second baffle 2. Therefore, the next embodiment makes further improvements.

[0033] In another embodiment, the height of the lower end of the second baffle plate 2 is higher than the top height of the parapet, and a latch 6 movable in the vertical direction is further provided on the back side of the second baffle plate 2. The lower end of the pin rod 601 of the latch 6 is connected to a vertical third baffle plate 10. When the pin rod 601 of the latch 6 is lifted, the height of the lower end of the third baffle plate 10 is higher than the top height of the parapet. When the pin rod 601 of the latch 6 falls, the lower end of the third baffle plate 10 abuts against the top of the parapet.

[0034] Specifically, the length of the third baffle 10 is generally consistent with the length of the second baffle 2 .

[0035] In addition, the third baffle 10 can be made of a skirting board, and the skirting board retaining part of the second baffle 2 is used to install the latch seat 602 (the part used to fix the pin rod 601) of the latch 6.

[0036] When the above embodiment is used, before pulling the second baffle 2, first lift the latch 6 so that the bottom of the third baffle 10 does not contact the top of the parapet. After the second baffle 2 is pulled into place, the pin 601 of the latch 6 is dropped so that the third baffle 10 is sealed between the lower end of the second baffle 2 and the top of the parapet. In this way, the lower end of the second baffle 2 will not touch the top of the parapet to generate friction during the movement, which reduces the movement resistance of the second baffle 2, reduces the noise, and avoids the wear of the skirting board of the second baffle 2.

[0037] In the aforementioned embodiment, in order to fix the second baffle plate 2 and the first baffle plate 1 with bolts, it is necessary to open through holes on the second baffle plate 2 and the first baffle plate 1 and then insert the bolts, which not only damages the surface of the second baffle plate 2 and the first baffle plate 1 but also makes the operation more cumbersome, so the next embodiment makes further improvements.

[0038] In another embodiment, a threaded hole is formed on the sleeve 3 , and a flat head screw 7 for fixing the cross bar 5 is threadedly connected in the threaded hole.

[0039] When the above embodiment is used, after the second baffle plate 2 is pulled into place, the second baffle plate 2 can be fixedly connected to the first baffle plate 1 by screwing the flat head screw 7 to tighten the cross bar 5 in the sleeve 3, thereby avoiding the need to open holes on the surface of the second baffle plate 2 and the first baffle plate 1 and making the operation simple and convenient.

[0040] In another embodiment, a C-shaped groove 8 is horizontally arranged on the top of the front side of the first baffle plate 1 , and a pulley 9 is vertically connected to the top of the back side of the second baffle plate 2 , and the pulley 9 is rollingly connected to the C-shaped groove 8 .

[0041] Here, the pulley 9 is preferably connected to the other side end of the top of the back of the second baffle 2 away from the connecting rod 4. In this way, both sides of the second baffle 2 are connected to the first baffle 1 to prevent the second baffle 2 from being deformed by unilateral force. At the same time, the pulley 9 and the C-shaped groove 8 also help the second baffle 2 to move more easily relative to the first baffle 1.

[0042] In another embodiment, the front sides of the first baffle 1 and the second baffle 2 are coated with reflective film. By providing the reflective film, the fence can reflect light at night, thereby warning pedestrians, motor vehicles or non-motor vehicles approaching the fence and avoiding collisions.

[0043] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
