Description

Technical Field

[0001] This utility model relates to the field of wiring technology in building engineering, and in particular to an auxiliary device for wiring electrical systems in buildings. Background Technology

[0002] Building electrical wiring refers to the process of threading wires or cables into pre-installed conduits, cable trays, or cable racks during the construction of building electrical engineering projects. This process plays a crucial role in the construction of the entire building electrical system, and its quality directly affects the safety, stability, and durability of the building electrical system.

[0003] However, when performing wiring work, it is necessary to manually feed the wires by hand. During the wiring work, workers usually have to maintain one posture for a long time to operate the cable, especially when threading long or many cables. The hand muscles will become fatigued due to prolonged exertion. Some pipes are in a vertical position. When the worker releases the cable due to hand fatigue, the cable will fall due to its own weight, requiring manual feeding of the cable again, which is quite troublesome. Therefore, an auxiliary device for building electrical wiring is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an auxiliary device for building electrical wiring, which solves the problem in the prior art that when a person's hand becomes fatigued and loosens the cable, the cable will fall off and need to be re-transported, which is quite troublesome.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary device for building electrical wiring, comprising a base, an adjustment mechanism at the top of the base, and a fixed conveying mechanism at the upper part of the base;

[0006] The fixed conveying mechanism includes a movable seat, a movable plate slidably connected to the inner wall of the movable seat, a rotating wheel rotatably connected to the inner wall of the left movable plate, a driven gear fixedly connected to the top of the rotating wheel, a ratchet post rotatably connected to the inner wall of the right movable plate, a guide wheel fixedly connected to the top of the ratchet post, a drive gear fixedly connected to the top of the guide wheel, a support block fixedly connected to the inner wall of the movable seat, a pawl post elastically connected to the inner wall of the movable seat by a spiral spring, and fasteners provided on the inner walls of the movable plates.

[0007] As a further description of the above technical solution:

[0008] The fastener includes a bolt, the outer wall of which is threaded to the top inner wall of the movable plate, and the bottom end of which is threaded to the inner wall of the movable seat.

[0009] As a further description of the above technical solution:

[0010] One end of the spiral spring is fixedly connected to the inner wall of the movable plate, and the other end of the spiral spring is fixedly connected to the outer wall of the pawl post. The outer arc surface of the pawl post is rotatably connected to the inner wall of the movable seat.

[0011] As a further description of the above technical solution:

[0012] The left side of the ratchet post contacts the outer tooth surface of the ratchet post, and the rear end of the ratchet post contacts the front end of the support block.

[0013] As a further description of the above technical solution:

[0014] The left side of the driving gear meshes with the right side of the driven gear, and multiple sets of arc-shaped grooves are formed on the outer wall of the guide wheel.

[0015] As a further description of the above technical solution:

[0016] The adjustment mechanism includes a motor. A telescopic rod and a support plate are fixedly connected to the top of the base. The upper movable end of the telescopic rod is fixedly connected to the bottom of the movable seat. A bidirectional threaded rod is rotatably connected to the inner wall of the support plate. A moving block is hinged to the outer wall of the bidirectional threaded rod. A connecting plate is rotatably connected to the top of the moving block. A caster wheel is fixedly connected to the bottom of the base.

[0017] As a further description of the above technical solution:

[0019] As a further description of the above technical solution:

[0020] The top of the connecting plate is hinged to the bottom of the movable seat, and the output end of the motor is fixedly connected to the left end of the bidirectional threaded rod.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, through the cooperation between the base and its fixed conveying mechanism, when the cable needs to be conveyed, the cable is fixed by the guide wheel and the rotating wheel, and then the drive gear is rotated to convey the cable. When the manual hand becomes fatigued, the drive gear will stop rotating. Due to the ratchet post and the pawl post, the drive gear will not rotate in the opposite direction, providing support for the cable and preventing the cable from falling due to gravity.

[0023] 2. In this utility model, through the cooperation between the adjustment mechanism and other structures, when it is necessary to transport cables through pipes of different heights, the motor is started. The motor drives the bidirectional threaded rod to rotate, thereby driving the movable seat to move vertically as a whole, thus completing the adjustment of the guide wheel and the rotating wheel, and enhancing the overall flexibility of the device.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-2One embodiment of this utility model is an auxiliary device for wiring electrical cables in buildings, including a base 1, an adjustment mechanism 3 at the top of the base 1, and a fixed conveying mechanism 2 at the upper part of the base 1. The fixed conveying mechanism 2 facilitates the wiring of electrical cables, and the adjustment mechanism 3 facilitates the adjustment of the position of the fixed conveying mechanism 2.

[0033] Reference Figures 2-4 The fixed conveying mechanism 2 includes a movable seat 201. A movable plate 204 is slidably connected to the inner wall of the movable seat 201. The movable plate 204 has two sets of horizontally movable plates, and is H-shaped to prevent it from falling off during movement. A rotating wheel 206 is rotatably connected to the inner wall of the left movable plate 204. A driven gear 207 is fixedly connected to the top of the rotating wheel 206, driving the rotating wheel 206 to rotate synchronously through the rotation of the driven gear 207. A ratchet post 209 is rotatably connected to the inner wall of the right movable plate 204. A guide wheel 205 is fixedly connected to the top of the ratchet post 209. The top of 05 is fixedly connected to a drive gear 208, which drives the guide wheel 205 to rotate through the rotation of the ratchet column 209. At this time, the drive gear 208 will also rotate synchronously. The inner wall of the movable seat 201 is fixedly connected to a support block 210. The inner wall of the movable seat 201 is elastically connected to a pawl column 211 through a spiral spring 203. The cooperation between the pawl column 211 and the ratchet column 209 causes the ratchet column 209 to rotate only in one direction, and the spiral spring 203 can play a reset role. The inner wall of the moving plate 204 is provided with fasteners, which limit and fix the moving plate 204.

[0034] Reference Figures 2-4 The fasteners include bolts 202. The outer wall of bolts 202 is threadedly connected to the inner wall of the top of the movable plate 204, and the bottom end of bolts 202 is threadedly connected to the inner wall of the movable seat 201. The movable plate 204 can be fixed by the bolts 202, and the cable can be clamped by the two sets of movable plates 204 moving towards the middle.

[0035] Reference Figures 2-4One end of the spiral spring 203 is fixedly connected to the inner wall of the movable plate 204, and the other end of the spiral spring 203 is fixedly connected to the outer wall of the pawl post 211. The outer arc surface of the pawl post 211 is rotatably connected to the inner wall of the movable seat 201. The elasticity of the spiral spring 203 enables the pawl post 211 to have the functions of reset and limit. The left side of the pawl post 211 contacts the outer tooth surface of the ratchet post 209. When the two are in contact, they are in a fixed state. The rear end of the pawl post 211 contacts the front end of the support block 210. The contact between the two prevents the pawl post 211 from rotating backward. The left side of the driving gear 208 meshes with the right side of the driven gear 207. The meshing between the two drives the driven gear 207 to rotate through the rotation of the driving gear 208. The outer wall of the guide wheel 205 is provided with multiple sets of arc-shaped grooves. The multiple sets of arc-shaped grooves are used to adapt to different signal cables and enhance the flexibility of the overall device.

[0036] Reference Figure 1 and Figure 5 The adjustment mechanism 3 includes a motor 301. A telescopic rod 307 and a support plate 306 are fixedly connected to the top of the base 1. The telescopic rod 307 is located outside the support plate 306. The upper movable end of the telescopic rod 307 is fixedly connected to the bottom end of the movable seat 201. The movement of the movable end drives the movable seat 201 to move vertically, thereby achieving the adjustment purpose. A bidirectional threaded rod 304 is rotatably connected to the inner wall of the support plate 306. A moving block 302 is hinged to the outer wall of the bidirectional threaded rod 304. The rotation of the bidirectional threaded rod 304 drives two sets of moving blocks 302 to move closer together or open apart. The top of the base 1 is rotatably connected to a connecting plate 303. When the moving block 302 moves, the connecting plate 303 will rotate. The bottom of the base 1 is fixedly connected to a universal wheel 305, which has a self-locking function. The bottom of the motor 301 is fixedly connected to the top of the base 1. The base 1 supports the motor 301. The top of the connecting plate 303 is hinged to the bottom of the movable seat 201. The rotation setting avoids motion interference. The output end of the motor 301 is fixedly connected to the left end of the bidirectional threaded rod 304. The output end of the motor 301 drives the bidirectional threaded rod 304 to rotate.

[0037] Working principle: When it is necessary to thread the cable, the motor 301 is started. The output end of the motor 301 drives the bidirectional threaded rod 304 to rotate. When the bidirectional threaded rod 304 rotates, the two sets of moving blocks 302 on its outer wall will move closer or open. Since the moving blocks 302 and the movable seat 201 are hinged through the connecting plate 303, when the moving blocks 302 move, they will drive the connecting plate 303 to rotate, which in turn drives the movable seat 201 to move vertically, thereby adapting to cable ducts of different heights.

[0038] After the movable seat 201 is adjusted, the electrical cable is placed between the rotating wheel 206 and the guide wheel 205. Then, the limiting bolt 202 is released, causing the two sets of moving plates 204 to move closer together, thereby clamping the cable. During this process, the rotating wheel 206 and the guide wheel 205 clamp the cable, thus fixing it in place. When the cable needs to be transported, the throttle on the drive gear 208 is driven to rotate, which in turn drives the driven gear 207 to rotate, causing the rotating wheel 206 and the guide wheel 205 to rotate simultaneously. Since the guide wheel 205 is driven by the ratchet column 209, and the ratchet column 209 can only rotate in one direction (under the action of the pawl column 211 and the spiral spring 203), the cable can only be transported along the rotation direction of the guide wheel 205. The outer wall of the guide wheel 205 has multiple sets of arc grooves of different types to accommodate different types of cables, ensuring that the cable will not slip or fall off during transport, thus improving the flexibility and applicability of the device.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
