Description

Technical Field

[0001] The utility model relates to the technical field of electrical construction, in particular to a wire threading device for building electrical construction. Background Art

[0002] Building electrical construction refers to a series of operations such as laying electrical circuits, installing and debugging electrical equipment in a building according to electrical design drawings and relevant specification requirements. During electrical construction, a wire threading device is an important auxiliary tool, usually composed of a flexible cable, a guiding head, an operating handle, etc. Its core function is to assist construction workers in smoothly passing wires, cables and other wire materials through pre-buried pipes or wire grooves. For example, in the patent with the application number CN202323171965.0, a pipe wire threading device for electrical construction is disclosed, belonging to the field of wire threading devices, including a support pipe. A first bracket is fixedly connected to the lower position of the support pipe, a second bracket is fixedly installed at the upper position of the support pipe, a rotating pipe is movably installed on the support pipe, a storage rack is fixedly connected to the rotating pipe, a wire rod is fixedly connected to the support pipe at a position on one side of the rotating pipe, and a wire loop is fixedly connected to the wire rod. By turning the handle, the screw rod and the fixed rod move laterally, so that the fixed rod moves laterally out of the chute and moves into the fixing groove of the rotating pipe, so that the rotating pipe is fixed. Then, the rotating block is rotated upward, so that the connecting ring moves upward, so that the connecting rings on both sides move upward, and the perforators on the front and rear sides of the wire loop are clamped upward, thereby fixing the perforators. When the wire threading device is vibrated during transportation, it is not easy to loosen, and the perforators are not easy to protrude and touch the ground, avoiding potential safety hazards.

[0003] However, for the existing wire threading devices, the baffle used to prevent the wire material from falling off has certain defects. The outer diameter of the baffle is a fixed size and cannot be adjusted according to actual use requirements. Moreover, the area of the baffle is usually large, which not only increases the overall occupied space but also causes great inconvenience during carrying and transportation, requiring more storage and transportation resources. At the same time, due to the fixed size of the baffle, in actual operation, it is impossible to flexibly adjust and change its state according to the specific length of the wound wire material. When the wound wire material is short, the oversized baffle is redundant and obstructive. Facing the winding requirements of wire materials of different lengths, the fixed-size baffle is difficult to adapt, making the flexibility and adaptability of the wire threading device greatly reduced during diverse construction scenarios, thus reducing its practicality and making it difficult to fully meet the actual use requirements in fields such as building electrical construction.

[0026] Please refer to Figures 1 to 5 :

[0027] Embodiment 1:

[0028] The present utility model provides a wire threading device for building electrical construction, including: a bracket 1, a turntable assembly 2, and an adaptive baffle 3; the turntable assembly 2 includes a winding outer roller 201, an adjusting inner roller 202, a positioning block 203, and an operating rod 204. The winding outer roller 201 is rotatably connected to the top of the bracket 1, and the adjusting inner roller 202 is rotatably connected to the inside of the winding outer roller 201. The positioning block 203 is inserted into the side of the winding outer roller 201, and the operating rod 204 is rotatably connected to the inside of the winding outer roller 201. A wire threading material is wound around the outside of the winding outer roller 201; the adaptive baffle 3 is rotatably connected to the inside of the winding outer roller 201.

[0029] Among them, the winding outer roller 201 and the adjusting inner roller 202 are coaxially arranged, and a rotating handle 2011 is provided on the side of the winding outer roller 201. During use, the entire turntable assembly 2 can be driven to rotate on the bracket 1 by rotating the rotating handle 2011, thereby realizing the winding and unwinding of the wire threading material wound around the winding outer roller 201, so as to realize the wire threading operation during building electrical construction. It is convenient and flexible to use, and the two wire blocking mechanisms can limit and block the wire threading material inside on both sides of the winding outer roller 201, thereby avoiding phenomena such as the wire threading material falling off during storage or transportation. It is convenient and stable to use.

[0030] Among them, the outer surface of the rod body of the operating rod 204 is provided with threads, and the operating rod 204 is screwed into the inside of the positioning block 203 through the rod body threads. During use, the effective use length of the adaptive baffle 3 (the radial distance that the adaptive baffle 3 extends out of the winding outer roller 201) can be adjusted by the operating rod 204. Therefore, when winding a wire threading material with a short length, the effective use length of the adaptive baffle 3 can be reduced to achieve the purpose of saving occupied space. When winding a wire threading material with a long length, the effective use length of the adaptive baffle 3 can be increased to achieve the purpose of winding and storing all the wire threading materials. It can be adjusted as needed, and the use is flexible.

[0031] Among them, four adaptive baffles 3 form a set of wire blocking mechanisms, and there are two sets of wire blocking mechanisms. The two sets of wire blocking mechanisms are symmetrically arranged inside the winding outer roller 201. The included angle between the four adaptive baffles 3 of the same set of wire blocking mechanisms is 90 degrees. A positioning gear 2022 is provided outside the rotating shaft of the adjusting inner roller 202, and a positioning rack 2031 is provided at the top of the positioning block 203. The teeth of the positioning rack 2031 and the positioning gear 2022 are engaged and driven. During use, when the operating rod 204 is rotated, the operating rod 204 can drive the positioning block 203 to move inside the winding outer roller 201 through the rod body thread. When the winding outer roller 201 moves, the positioning rack 2031 can drive the adjusting inner roller 202 to rotate independently of the winding outer roller 201 through the positioning gear 2022. An adaptive slot 2021 is provided on the adjusting inner roller 202, and an adaptive rod 301 is provided on the side of the adaptive baffle 3. The adaptive rod 301 is inserted into the adaptive slot 2021. When the adjusting inner roller 202 rotates, the adaptive slot 2021 can drive the adaptive baffle 3 to rotate through the adaptive rod 301. When the adaptive baffle 3 rotates, its plate body can extend out of the inside of the winding outer roller 201 in the radial direction of the winding outer roller 201, thereby changing the effective blocking outer diameter of the wire blocking mechanism for the threading wire, and the regulation is convenient and fast.

[0032] The working principle of this embodiment: By rotating the handle 2011, the entire turntable assembly 2 can be driven to rotate on the bracket 1, thereby realizing the winding and unwinding of the threading wire wound on the winding outer roller 201, so as to realize the threading operation during the construction of building electrical engineering. It is convenient and flexible to use. And the two sets of wire blocking mechanisms can limit and block the threading wire inside the winding outer roller 201 on both sides, thereby avoiding phenomena such as the threading wire falling off during storage or transportation. The effective use length of the adaptive baffle 3 (the radial distance that the adaptive baffle 3 extends out of the winding outer roller 201) can be adjusted through the operating rod 204. Thus, when winding a threading wire with a shorter length, the effective use length of the adaptive baffle 3 can be reduced to achieve the purpose of saving occupied space. When winding a threading wire with a longer length, the effective use length of the adaptive baffle 3 can be increased to achieve the purpose of winding and storing all the threading wires, and it can be adjusted according to needs. When the operating rod 204 is rotated, the operating rod 204 can drive the positioning block 203 to move inside the winding outer roller 201 through the rod body thread. When the winding outer roller 201 moves, the positioning rack 2031 can drive the adjusting inner roller 202 to rotate independently of the winding outer roller 201 through the positioning gear 2022. When the adjusting inner roller 202 rotates, the adaptive slot 2021 can drive the adaptive baffle 3 to rotate through the adaptive rod 301. When the adaptive baffle 3 rotates, its plate body can extend out of the inside of the winding outer roller 201 in the radial direction of the winding outer roller 201, thereby changing the effective blocking outer diameter of the wire blocking mechanism for the threading wire.

[0033] In another embodiment, the fixing of the winding outer roller 201 can be achieved by passing a pin rod through both the winding outer roller 201 and the bracket 1 simultaneously, so as to avoid the phenomenon that the winding outer roller 201 rotates during transportation or transfer, resulting in the loosening or release of the threading wire. Further, the stability of the device is improved, and operations such as threading construction can be achieved by pulling out the pin rod during subsequent threading construction.
