[0002] Construction site fencing is an essential component of safe and civilized construction. Besides ensuring site management and property safety, it also enhances the internal and external environment. Fencing not only represents the image of the construction company, but also reflects the level of development of a city's construction project management and the industry. It also directly impacts residents' living environment and the city's landscape.

[0003] The height of the fence at the construction site needs to be coordinated with the surrounding environment. In a busy commercial area, the height of the fence should be kept as low as possible to avoid affecting the operations of surrounding businesses. In residential areas, the height of the fence should be kept as appropriate as possible so as not to affect the lives of residents. In construction areas, the height of the fence should be kept as high as possible to prevent objects on the construction site from overflowing the fence and endangering the safety of pedestrians in the surrounding area. Therefore, it is necessary to use fences of corresponding models according to the construction site environment. According to patent publication number (CN113914706B), a construction fence is disclosed, including a unit railing and several movable bases installed at the bottom of the unit railing. The unit railing includes several vertical bars and horizontal bars, and the vertical bars and horizontal bars are connected and fixed at the intersection: in actual use, the hanging board can conveniently display construction information and also play a role of protective isolation. However, the design size of the hanging board is fixed and cannot be adjusted according to actual needs. This fixedness limits its use in different construction sites. Utility Model Content

[0026] Please refer to Figures 1 to 7 .

[0027] The present embodiment provides a construction enclosure with adjustable height, comprising a mounting base 1; a first lifting column 2, with first lifting columns 2 mounted on both sides of the mounting base 1, the first lifting columns 2 being provided with first mounting grooves 9, in which locking components 7 are mounted; a second lifting column 3, with a second lifting column 3 sleeved on one end of the first lifting column 2 away from the mounting base 1, the second lifting column 3 being able to slide back and forth along the axial direction of the first lifting column 2, the second lifting column 3 being provided with a plurality of locking holes 6 cooperating with the locking components 7 along the axial direction; a first enclosure 4, with the mounting base 1 mounted A first enclosure 4, the first enclosure 4 is located between the two first lifting columns 2; a second enclosure 5, both ends of the second enclosure 5 are connected to the lifting columns 3, and the second enclosure 5 is provided with a receiving groove 8 for receiving the first enclosure 4; a locking assembly 7, the locking assembly 7 includes a first elastic member and a wedge-shaped locking member, one end of the first elastic member is connected to the surface wall of the first mounting groove 9, and the other end of the first elastic member is connected to the locking member, and the locking member can be locked with the locking hole 6; when the second lifting column 3 slides away from the first lifting column 2, the locking of the locking member by the locking hole 6 can be released.

[0028] In this embodiment, the lifting column assembly consists of a first lifting column 2 and a second lifting column 3. The second lifting column 3 is provided with a sliding groove on the side facing the first lifting column 2. One end of the first lifting column 2 is connected to the mounting base 1, and the other end of the first lifting column 2 is located in the sliding groove of the second lifting column 3. The second lifting column 3 can slide toward the first lifting column 2 and can also slide away from the first lifting column 2. The mounting base 1 is equipped with a first enclosure 4, which is located between the two first lifting columns 2. A second enclosure 5 is installed between the two second lifting columns 3. The second enclosure 5 is provided with a storage groove 8 on the side facing the first enclosure 4. The size of the storage groove 8 is adapted to the size of the first enclosure 4. Construction workers adjust the height of the fence according to the construction site. In busy commercial areas, the height of the fence should be kept as low as possible. Construction workers first unlock the locking hole 6 with the locking assembly 7, push the second lifting column 3 toward the first lifting column 2, and after the second lifting column 3 moves to the preset position, mate the locking assembly 7 with the locking hole 6 in the corresponding position, thereby securing the first and second lifting columns 2 and 3. The fence formed by the first and second fences is relatively small in size and suitable for construction projects in commercial areas. In residential areas, the height of the fence should be kept as appropriate as possible. Construction workers first unlock the locking hole 6 with the locking assembly 7, push the second lifting column 3 relative to the first lifting column 2, and mate the locking assembly 7 with the locking hole 6 near the center of the multiple locking holes 6, thereby securing the first and second lifting columns 2 and 3. The fence formed by the first and second fences is of moderate size and suitable for construction projects in residential areas. In the construction area, the height of the fence is kept as high as possible to prevent objects in the construction site from overflowing the fence. The construction worker first releases the lock of the locking component 7 on the locking hole 6, pushes the second lifting column 3 away from the first lifting column 2, and moves until the second lifting column 3 moves to the preset position. Then, the locking component 7 is matched with the locking hole 6 at the corresponding position, thereby fixing the first lifting column 2 and the second lifting column 3. The fence composed of the first fence 4 and the second fence is large in size and is suitable for construction projects in the construction area (please refer to Figure 1 、 Figure 2 and Figure 3). Furthermore, one side of the first lifting column 2 is located inside the second lifting column 3. The first lifting column 2 is provided with a first mounting groove 9. One end of the first elastic member is connected to the surface wall of the first mounting groove 9, and the other end of the first elastic member is connected to the locking member. The outer side wall of the locking member can slide with the surface wall of the first mounting groove 9. When the second lifting column 3 slides upward relative to the first lifting column 2, the lower side of the locking hole 6 can be pressed against the locking member. The lower side of the locking member is a wedge-shaped structure. After the locking member is under pressure, it is pressed against the first elastic member. After the first elastic member is compressed, the locking member enters the first mounting groove 9. The construction worker continues to push the second lifting column 3 upward until the locking member enters the corresponding locking hole 6, so that the enclosure reaches the appropriate size. The construction worker can adjust the enclosure according to different construction sites to meet the needs of different construction sites; the construction worker does not need to prepare enclosures of multiple sizes to cope with different construction sites, which greatly reduces construction costs.

[0029] Furthermore, in the present invention, the first elastic member includes a first return spring 10 ; one end of the first return spring 10 is connected to the surface wall of the first installation groove 9 , and the other end of the first return spring 10 is connected to the locking member.

[0030] In this embodiment, the first return spring 10 can apply a thrust to the locking member so that the locking member enters the corresponding locking hole 6 (see Figure 4 and Figure 5 The locking hole 6 can also be pressed toward the locking member to compress the first return spring 10, and the locking member enters the first installation groove 9. After the locking member is moved to the preset locking hole 6, the first return spring 10 pushes the locking member to cooperate with the above-mentioned locking hole 6.

[0031] Furthermore, in the present invention, the locking member includes a connecting portion 11 and a locking portion 12 ; one end of the connecting portion 11 is connected to the first return spring 10 , and the other end of the connecting portion 11 is rotationally engaged with the locking portion 12 .

[0032] In this embodiment, the locking member is composed of a connecting portion 11 and a locking portion 12. The locking portion 12 can rotate relative to the connecting portion 11. When the wedge-shaped structure of the locking portion 12 is downward, the construction worker can push the second lifting column 3 upward, and the lower side of the locking hole 6 can press against the locking portion 12. After the first return spring 10 is compressed, the locking portion 12 enters the first installation groove 9, and the second lifting column 3 can continue to move upward, facilitating the construction worker's operation of increasing the size of the enclosure. When the wedge-shaped structure of the locking portion 12 is upward, the construction worker can push the second lifting column 3 downward, and the upper side of the locking hole 6 can press against the locking portion 12. After the first return spring 10 is compressed, the locking portion 12 enters the first installation groove 9, and the second lifting column 3 can continue to move downward, facilitating the construction worker's operation of reducing the size of the enclosure.

[0033] Furthermore, in the present invention, the locking portion 12 is provided with a second mounting groove 13 , a rotating member 17 is installed on the surface wall of the second mounting groove 13 , and the connecting portion 11 is circumferentially provided with a rotating groove 16 that cooperates with the rotating member 17 .

[0034] In this embodiment, the locking portion 12 has a second mounting slot 13 on the side facing the connecting portion 11. One side of the connecting portion 11 is located within the second mounting slot 13 and has a rotation slot 16 circumferentially formed therein. A rotation member 17 within the second mounting slot 13 is located within the rotation slot 16, allowing the locking portion 12 to rotate relative to the connecting portion 11. When the wedge-shaped structure of the locking portion 12 is rotated upward, the second lifting column 3 can slide toward the first lifting column 2, reducing the size of the enclosure. When the wedge-shaped structure of the locking portion 12 is rotated downward, the second lifting column 3 can slide away from the first lifting column 2, increasing the size of the enclosure. This allows construction workers to conveniently adjust the enclosure size based on the actual construction site.

[0035] Furthermore, the present invention also includes a second return spring 14; the outer side wall of the connecting portion 11 is circumferentially installed with a first mounting plate 20, and the surface wall of the second mounting groove 13 is circumferentially installed with a second mounting plate 15, the second return spring 14 is sleeved on the connecting portion 11, one end of the second return spring 14 abuts against the first mounting plate 20, and the other end of the second return spring 14 abuts against the second mounting plate 15, and the second return spring 14 is in a compressed state; the side of the rotating groove 16 away from the second return spring 14 is connected to the first limiting groove 18, and the other side of the rotating groove 16 away from the second return spring 14 is connected to the second limiting groove 19; when the rotating member 17 cooperates with the first limiting groove 18, the first lifting column 2 and the second lifting column 3 can slide toward each other; when the rotating member 17 cooperates with the second limiting groove 19, the first lifting column 2 and the second lifting column 3 can slide in opposite directions.

[0036] In this embodiment, the second return spring 14 is sleeved on the connecting portion 11, one end of the second return spring 14 abuts against the first mounting plate 20, and the other end of the second return spring 14 abuts against the second mounting plate 15. The second return spring 14 is always in a compressed state, one end of the second return spring 14 applies a thrust to the first mounting plate 20, and the other end of the second return spring 14 applies a thrust to the second mounting plate 15. The first limiting groove 18 and the second limiting groove 19 are respectively located at the two ends of the rotating groove 16. When the rotating member 17 is inserted into the first limiting groove 18, the wedge-shaped structure of the locking portion 12 faces downward, and the second lifting column 3 can slide downward to reduce the size of the enclosure (please refer to Figure 6 and Figure 7). When the rotating member 17 is stuck in the second limiting groove 19, the wedge-shaped structure of the locking part 12 faces, and the second lifting column 3 can slide upward to increase the size of the enclosure. Specifically, when the construction worker adjusts the spatial position of the locking part 12, he needs to first pull the locking part 12 to move it away from the connecting part 11, so that the rotating member 17 moves into the rotating groove 16, and then rotate the locking part 12 to move the rotating member 17 to the first limiting groove 18 or the second limiting groove 19, and then cancel the pulling force on the locking part 12. The locking part 12 moves toward the connecting part 11 under the thrust of the second return spring 14, so that the rotating member 17 can be stuck in the first limiting groove 18 or the second limiting groove 19. The second return spring 14 always remains in a compressed state, so that the rotating member 17 can be firmly stuck in the first limiting groove 18 or the second limiting groove 19. The above operation can be repeated when the construction worker adjusts the spatial posture of the locking part 12. After the relative positions of the locking portion 12 and the connecting portion 11 are limited, the construction worker can easily adjust the size of the block, thereby preventing the locking portion 12 and the connecting portion 11 from rotating erroneously, thereby affecting the construction worker's operation.

[0037] Furthermore, in the present invention, the outer side walls on both sides of the locking portion 12 are provided with grooves.

[0038] In this embodiment, when adjusting the size of the enclosure, the construction worker needs to adjust the spatial position of the locking portion 12. To adjust the spatial position of the locking portion 12, the construction worker first needs to pull the locking portion 12 to make the rotating member 17 come out of the first limiting groove 18 or the second limiting groove 19. During operation, the construction worker can put two fingers into the pulling groove to make it easier to pull out the locking portion 12.

[0039] In summary, the embodiments of the present invention provide a construction fence with adjustable height. Construction workers adjust the height of the fence according to the construction site. In a busy commercial area, the height of the fence should be kept as low as possible. The construction worker first releases the lock of the locking assembly 7 on the locking hole 6, and then matches the locking assembly 7 with the locking hole 6 at the corresponding position, thereby reducing the size of the fence formed by the first fence 4 and the second fence, which is suitable for construction projects in commercial areas. In residential areas, the height of the fence should be kept as appropriate as possible. The construction worker first releases the lock of the locking assembly 7 on the locking hole 6, and then matches the locking assembly 7 with the locking hole 6 near the middle among the multiple locking holes 6, so that the size of the fence formed by the first fence 4 and the second fence is moderate, which is suitable for construction projects in residential areas. In construction areas, the height of the fence should be kept as high as possible to prevent objects on the construction site from overflowing from the fence. The construction worker first releases the lock of the locking assembly 7 on the locking hole 6, and then matches the locking assembly 7 with the locking hole 6 at the corresponding position, so that the size of the fence formed by the first fence 4 and the second fence is larger, which is suitable for construction projects in construction areas. Construction workers can adjust the fences according to different construction sites to meet the needs of different construction sites; construction workers do not need to prepare fences of multiple sizes to deal with different construction sites, which greatly reduces construction costs.
