Description

Technical Field

[0001] The utility model belongs to the technical field of engineering enclosures, and particularly relates to engineering construction enclosures. Background Art

[0002] The construction fence mainly plays the role of isolation, separating the construction area from the outside world, ensuring construction safety, and reducing the impact of construction on the surrounding area. It is an indispensable facility on the construction site. However, the current construction fence has many obvious disadvantages in that the width is inconvenient to adjust. Since the width of the fence cannot be flexibly adjusted, it is often impossible to perfectly adapt to construction sites of different sizes and shapes. This may lead to unreasonable space utilization, either the fence range is too large to waste resources, or it is too small to effectively isolate the construction area from the outside world, affecting construction safety and the surrounding environment. When the fence range needs to be temporarily changed during the construction process, the non-adjustable width will cause great inconvenience. It may be necessary to rearrange the fence, which not only consumes manpower and material resources, but also delays the construction progress and increases the project cost. The non-adjustable fence width also limits the flexibility and maneuverability of the construction. If the construction scope needs to be increased or reduced during the construction process to cope with emergencies or new construction needs, this kind of fence will not meet the requirements, which will affect the smooth progress of the entire project. In short, the disadvantage of the inconvenience of adjusting the width of the construction fence has brought many troubles and restrictions to the construction, which is not conducive to the efficient, safe and orderly development of the project. Therefore, it is necessary to develop construction fences to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 5 The utility model provides a technical solution: a construction enclosure, comprising: a main frame 1, a column 3 and a blocking net 5, the column 3 is installed on the left side of the main frame 1, and a side rod 6 is installed in front of the column 3, a retracting cavity 2 is provided at the inner rear of the main frame 1, and an extension frame 4 is provided on the right side of the retracting cavity 2;

[0024] An upper rack 12 is installed in the middle of the upper part of the extension frame 4, and a limit plate 13 is installed on the front and rear sides of the upper rack 12 respectively. A rotating gear 11 is provided on the left side above the upper rack 12, and a driving motor 10 is installed behind the rotating gear 11. The driving motor 10 is installed on the inner side of the top plate 8, and a rotating rod 9 is installed on the front side above the top plate 8;

[0025] The upper end of the rotating rod 9 passes through the top of the main frame 1, and a side fixing plate 14 is installed in the front and rear of the left side of the gear respectively. A bottom groove 7 is opened in the middle of the lower part of the extension frame 4, and a rotating wheel 15 is installed in the middle of the lower right side of the retracting cavity 2, and a fixed shaft 16 is installed in the middle of the rotating wheel 15.

[0026] The rotating gear 11 is meshed with the upper rack 12 , and the upper ends of the two side fixing plates 14 are fixed to the top plate 8 , and the lower ends thereof are both located at the front and rear sides below the upper rack 12 .

[0027] The rotating wheel 15 is located inside the bottom groove 7 , and a column 3 is also installed on the right side of the extension frame 4 .

[0028] A blocking net 5 is installed in the middle of the extension frame 4 and in the middle of the front side of the main frame 1. The main frame 1 is in a U-shaped structure, and there is a space on its right side for the left end of the extension frame 4 to rotate.

[0029] The width inside the retraction cavity 2 is greater than the width of the extension frame 4, and the lower end of the fixed shaft 16 is fixed to the main frame 1.

[0030] A bearing is installed in the middle of the rotating wheel 15. The upper end of the fixed shaft 16 is connected to the inner side of the bearing, and the output shaft of the driving motor 10 is connected to the middle position of the rotating gear 11.

[0031] Please refer to Figures 1 to 4 , as the first embodiment of the present utility model: When in use, the driving motor 10 can be started to rotate forward to drive the rotating gear 11 to rotate clockwise. Since the rotating gear 11 meshes with the upper rack 12, when the rotating gear 11 rotates, it can drive the upper rack 12 to move to the right. Thus, the upper rack 12 simultaneously drives the extension frame 4 to move to the right in the retraction cavity 2, and the required width can be adjusted according to actual usage requirements, thereby realizing the adjustment of the enclosure width. When it is necessary to retract, the driving motor 10 is reversed. Combining the above, the extension frame 4 moves to the left and enters the inside of the retraction cavity 2, thereby realizing the retraction of the extension frame 4. Through the above steps, the final effect is that the enclosure width can be adjusted according to actual usage requirements. By extending the extension frame 4, the enclosure can be adjusted to the required width for use, which can accurately adapt to the actual requirements of different scenarios, flexibly adjust the enclosure width, improve the applicability and practicability, and the extension and retraction operations of the extension frame 4 are convenient, and the enclosure size can be changed quickly, saving time and manpower.

[0032] Please refer to Figures 1 to 5 , as the second embodiment of the present utility model: Based on the further elaboration of the first embodiment, when it is necessary to install the enclosure at a corner, move the left end of the extension frame 4 to the space where the left end of the extension frame 4 rotates, and then the right-side column 3 can be rotated. The column 3 can drive the two limiting plates 13 to rotate through the extension frame 4. When the limiting plates 13 rotate, they can drive the top plate 8 to rotate through the two side fixing plates 14. The top plate 8 drives the rotating rod 9 to rotate. At the same time, the extension frame 4 drives the bottom groove 7 to rotate, and the bottom groove 7 can drive the rotating wheel 15 to rotate, thereby facilitating the rotation adjustment of the enclosure to the corner state. After the adjustment is completed, make one side of the retraction cavity 2 inward, and the lower ends of the two columns 3 can be buried in the ground, thereby improving the stability of the enclosure and enhancing the adaptability of the enclosure in different sections. Whether it is a right-angle bend or other special-angle sections, it can be easily dealt with to ensure the effective isolation of the construction area.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
