Description

Technical Field

[0001] The utility model relates to the technical field of isolation, in particular to an isolation device for construction. Background Art

[0002] During the communication construction process, an isolation device is required to separate the construction area from other areas, preventing unauthorized personnel from entering the construction area and reducing the incidence of construction accidents.

[0003] An isolation device for power communication construction with the publication number of CN220151071U in the prior art includes a base. A telescopic isolation frame is arranged on the top of the base. An isolation net is detachably connected inside the telescopic isolation frame. A group of cross - arranged support rods are arranged on both sides of the isolation net, and the middle positions of the two groups of support rods are rotatably connected through pin shafts. It is made of plastic material and PU material for the base and the telescopic isolation frame respectively.

[0004] The overall weight of this isolation device is relatively light and convenient to carry. However, due to the overall assembled design, when transporting, each component needs to be disassembled and carried. The metal net also needs to be additionally wound and carried. After arriving at the construction site, it needs to be assembled again. The time consumed for disassembly and assembly is relatively long, reducing the layout efficiency of the isolation device. And carrying each component independently after disassembly also increases the risk of loss. Therefore, improvements are proposed. Summary of the Utility Model

[0005] The utility model is proposed to solve the disadvantages existing in the prior art, and provides an isolation device for construction.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: An isolation device for construction includes a housing. A storage housing is fixedly connected between the two housings. A winding roller is rotatably connected to the inner walls on both sides of the storage housing. A metal net is fixedly wound around the outer surface of the winding roller, and the metal net penetrates through the inner top wall of the storage housing and extends upward. A cross bar is fixedly connected to the top of the metal net;

[0007] Two bidirectional moving components are installed inside the two housings. The two movable ends of the two bidirectional moving components are rotatably connected to a scissor - type telescopic frame, and the top end of the scissor - type telescopic frame is rotatably connected to the cross bar;

[0008] Two transmission components are commonly installed between the two bidirectional moving components and the winding roller;

[0009] A manual driving component is commonly installed between a single housing and the adjacent transmission component.

[0010] Furthermore, both of the two bidirectional moving components include bidirectional screws, and the bidirectional screws are rotatably installed on the inner walls of both sides of the housing. Two sliding seats are symmetrically sleeved on the outer surface of the bidirectional screws in a threaded manner, and the sliding seats are rotatably connected to the adjacent scissor-type telescopic frames. When driving the two sliding seats to approach each other, the scissor-type telescopic frames extend, thereby pushing the cross bar upward. On the contrary, the cross bar moves downward.

[0011] Furthermore, two sliding rails are symmetrically and slidably connected to the bottom of the sliding seat, and the sliding rails are fixedly connected to the housing. The sliding rails have a limiting effect on the sliding seat, which can ensure the stability of the sliding seat movement.

[0012] Furthermore, both of the two transmission components include worms, and the worms are rotatably installed on the inner wall of one side of the adjacent housing and fixedly connected to the winding rollers. A worm gear is meshed with the outer surface of the worm, and the worm gear is fixedly sleeved on the outer surface of the adjacent bidirectional screw, which can make the bidirectional moving component and the winding roller operate synchronously.

[0013] Furthermore, the manual driving component includes a handwheel, and the handwheel is arranged outside the adjacent housing. A rotating shaft is fixedly connected to one side of the outer surface of the handwheel, and the rotating shaft penetrates through the outer wall of the adjacent housing and extends to the inside and is rotatably connected thereto, and the rotating shaft is fixedly connected to the adjacent worm. The housing has a supporting effect on the rotating shaft, which is beneficial to the installation of the rotating shaft and the handwheel.

[0014] Furthermore, a plurality of reflective stickers are fixedly adhered to one side of the outer surface of the metal mesh. The reflective stickers have a striking effect and have a good prompting effect.

[0015] Furthermore, bases are fixedly connected to the bottoms of both of the two housings. A counterweight groove is formed on one side of the outer surface of each of the two bases. Counterweight items can be placed in the counterweight groove during use to increase the weight of the base and avoid tipping over during the whole use process.

[0016] The beneficial effects of the utility model:

[0017] When the utility model is in use, for this construction isolation device, through the arranged storage shell, winding roller, metal mesh, cross bar, bidirectional moving component, scissor-type telescopic frame, transmission component and manual driving component, the whole adopts an integrated telescopic design without disassembly and assembly. After transporting it to the set position during use, it can be directly unfolded for use, which improves the layout efficiency of the isolation device and can also reduce the risk of loss. At the same time, the overall height can also be adjusted according to the actual isolation requirements, improving the overall applicability. Description of the drawings

A through hole is provided at the top of the storage case 5 to facilitate the movement of the metal mesh 4. A cross bar 6 is fixedly connected to the top of the metal mesh 4. The storage case 5 and the housing 1 are both made of plastic products, which can reduce the overall weight and facilitate handling.

[0026] A two-way moving component is installed inside each of the two shells 1. The two moving ends of the two two-way moving components are jointly rotatably connected to a scissor-type telescopic frame 8, and the top end of the scissor-type telescopic frame 8 is rotatably connected to the cross bar 6. Each of the two two-way moving components includes a two-way screw rod 14, and the two-way screw rod 14 is rotatably installed on the inner walls of both sides of the shell 1. Two sliding seats 16 are symmetrically sleeved on the outer surface of the two-way screw rod 14 in a threaded manner. When the two-way screw rod 14 rotates, it can drive the two sliding seats 16 to approach or move away from each other, and the sliding seat 16 is rotatably connected to the adjacent scissor-type telescopic frame 8. Two slide rails 15 are symmetrically and slidably connected to the bottom of the sliding seat 16, and the slide rails 15 are fixedly connected to the shell 1. The slide rails 15 have a limiting effect on the sliding seat 16, which can ensure the stability of the movement of the sliding seat 16.

[0027] A transmission component is jointly installed between each of the two two-way moving components and the winding roller 12. Each of the two transmission components includes a worm 11, and the worm 11 is rotatably installed on the inner wall of one side of the adjacent shell 1 and fixedly connected to the winding roller 12. A worm gear 13 is meshed with the outer surface of the worm 11, and the worm gear 13 is fixedly sleeved on the outer surface of the adjacent two-way screw rod 14. When the winding roller 12 rotates, it will drive the worm 11 to rotate, and the worm 11 can drive the two-way screw rod 14 to rotate through the worm gear 13.

[0028] A manual driving component is jointly installed between a single shell 1 and the adjacent transmission component. The manual driving component includes a handwheel 7, and the handwheel 7 is arranged outside the adjacent shell 1.
