Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction technology, and specifically relates to a wire protection device for cable boxes in steel truss floor decking. Background Technology
[0002] In steel structure building construction, the floor slabs are truss floor decking. In electrical installation, junction boxes need to be pre-drilled (i.e., junction box holes need to be pre-drilled) on the truss floor decking before the conduits are laid.
[0003] Generally, a cutting machine is used to make holes in the floor decking according to the size of the junction box, that is, to make rectangular junction box holes. The burrs and corners of the junction box holes are extremely sharp, which will affect the subsequent wiring and pose a risk of scratching or pulling the wires, affecting construction. Furthermore, if the work is carried out with electricity, there is a high risk of safety hazards.
[0004] Currently, there is no very suitable protective device to solve the above-mentioned technical problems, so it is urgent to find a solution. Utility Model Content
[0005] This utility model provides a wire protection device for cable boxes in steel truss floor decking, which can solve the problems pointed out in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a device frame is provided, one side of which is provided with a fixing component for fixing the device to a junction box hole, and the other side of which is provided with a protective pulley assembly, which can prevent the wire from rubbing against the edge of the junction box hole.
[0007] Preferably, the fixing component includes a fixing limiting member fixed to one end of the device frame and a sliding limiting member located at the other end, and the device is supported on the wire box hole by the fixing limiting member and the sliding limiting member at both ends.
[0008] Preferably, both the fixed limiting member and the sliding limiting member are angle plates.
[0009] Preferably, the two ends of the sliding limiting member are slidably connected to the device frame, and an elastic member is provided between the sliding limiting member and the device frame. The elastic member presses the sliding limiting member to slide away from the fixed limiting member.
[0010] Preferably, the sliding limit member has sliding rods at both ends, and the device frame has a sliding sleeve that cooperates with the sliding rods at the corresponding position. The elastic element is a compression spring, which is disposed inside the sliding sleeve.
[0011] Preferably, a handle is connected to the slide rod.
[0012] Preferably, the protective pulley assembly includes a protective ring and a plurality of pulleys.
[0013] Preferably, the protective ring is a circular protective ring, and the circular protective ring has a plurality of pulleys arranged in a circular array.
[0014] Beneficial effects: This utility model provides a wire protection device for cable boxes in steel truss floor decks, which has the advantages of simple structure, easy operation, and high stability. It can effectively prevent wires from being scratched during the wire pulling process, and can be adapted to various specifications of cable box holes. It has good practicality and wide applicability. Attached Figure Description

[0019] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.
[0020] Example 1:
[0021] like Figure 1-2 As shown, a wire protection device for a steel truss floor deck junction box includes a device frame 1. One side of the device frame 1 is provided with a fixing component for fixing the device to the junction box hole, and the other side of the device frame 1 is provided with a protective pulley assembly. The protective pulley assembly can prevent the wire from rubbing against the edge of the junction box hole. The protective pulley assembly includes a protective ring 31 and several pulleys 32. The protective ring 31 limits the wire and prevents it from contacting the edge of the junction box hole. The pulleys 32 guide the wire to slide, making the process of pulling the wire easier and less strenuous.
[0022] Specifically, the fixing components include a fixed limiting member 21 fixed at one end of the device frame 1 and a sliding limiting member 22 located at the other end. The device is supported on the wire box hole by the fixed limiting member 21 and the sliding limiting member 22 at both ends. Both the fixed limiting member 21 and the sliding limiting member 22 are corner plates. The bent part of the corner plate plays a limiting role and improves stability.
[0023] Specifically, the two ends of the sliding limit member 22 are slidably connected to the device frame 1, and an elastic member 23 is provided between the sliding limit member 22 and the device frame 1. The elastic member 23 presses the sliding limit member 22 to slide away from the fixed limit member 21. The two ends of the sliding limit member 22 are respectively provided with sliding rods 24. The device frame 1 is provided with a sliding sleeve 25 that cooperates with the sliding rods 24 at the corresponding position. The elastic member 23 is a compression spring, which is set inside the sliding sleeve 25.
[0024] In some embodiments, a handle 26 is connected to the slide bar 24, and the handle 26 connects between the two slide bars 24.
[0025] In some embodiments, the protective ring 31 is a circular protective ring with a plurality of pulleys 32 arranged in a circular array around its circumference, and the protective ring 31 is fixed on the other side of the device frame 1.
[0026] The working principle of this utility model is as follows: After the handle 26 compresses the sliding limit member 22 inward, the fixed limit member 21 and the sliding limit member 22 at both ends are locked in the wire box hole. Under the action of the compression spring, the fixed limit member 21 and the sliding limit member 22 will be locked on the wire box hole, that is, the device is stabilized on the wire box hole. The protective pulley assembly plays a role in limiting and protecting the wire and guiding it smoothly.
[0027] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
