Description

Technical Field

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

[0002] Building electrical wiring installation devices are tools used for laying electrical wiring within buildings. Their main function is to ensure the accurate installation of electrical lines such as wires and cables. The main structure of a building electrical wiring installation device is a wiring frame. In use, the cable reel is fitted onto the outside of the wiring frame, and an axial limiting structure prevents the cable reel from moving axially.

[0003] Existing building electrical cable laying devices, due to their generally fixed cable laying frames, are only suitable for cable reels of specific inner diameters. Cable reels with smaller inner diameters cannot be placed on the frames, while those with larger inner diameters tend to wobble, compromising stability. This necessitates the design of multiple cable laying devices to accommodate various cable reels of different inner diameters, resulting in high equipment costs. Therefore, there is an urgent need for a building electrical cable laying device that can accommodate cable reels of different inner diameters. Utility Model Content

[0004] To overcome the technical defects of existing building electrical wiring devices that cannot be used with cable reels of different inner diameters, this utility model provides a building electrical wiring device.

[0005] The electrical wiring device for buildings provided by this utility model includes a base and a wiring rack mounted on the base. The wiring rack is formed by two sets of wiring assemblies symmetrically distributed on the left and right sides. The wiring assembly includes:

[0006] Connector, which is mounted on the base;

[0007] The mounting component is fixed above the connector. Two vertically distributed movable blocks are mounted on the mounting component. The two movable blocks are driven to move closer to or further away from each other. Each movable block is fixed with a horizontally arranged support rod that extends toward another set of wire feeding components.

[0008] A limiting rod, which is fixed to the support rod and perpendicular to the support rod;

[0009] At least one set of cable-laying assembly connectors is driven to move in the left and right directions, and the limiting rods of the two sets of cable-laying assemblies are used to limit the left and right ends of the cable reel, respectively.

[0010] Optionally, in each wire feeding assembly, a rotating drum is installed on the side of the support rod opposite to the other support rod, and the axis of the rotating drum is arranged in the left-right direction.

[0011] Optionally, the limiting rod can slide left and right along the corresponding support rod and is equipped with a locking device for fixing the limiting rod to the support rod.

[0012] Optionally, in each wire feeding assembly, a slide rail is installed on the side of the support rod facing the other support rod. The slide rail is arranged in the left-right direction and connected to a slider. The limiting rod is fixed on the slider and extends to the front and rear sides of the slider. The locking fastener is a fastener screwed onto the slider and abutting against the slide rail.

[0013] Optionally, the connectors of both wire feeding assemblies can be driven to move in the left-right direction and move closer or further apart from each other.

[0014] Optionally, the base has a strip groove arranged in the left-right direction, and a first screw is rotatably installed in the strip groove. The first screw has two threads with different directions of rotation. The connectors of the two sets of wire feeding assemblies are slidably installed in the strip groove and screwed onto the two threads of the first screw respectively.

[0015] Optionally, the mounting component has a groove on its surface facing another mounting component. A second screw is rotatably mounted in the groove and a guide post is fixed therein. Both the second screw and the guide post are arranged vertically. The second screw has two threads with different directions of rotation. Two moving blocks located on the same mounting component are slidably fitted on the guide post and respectively screwed onto the two threads of the second screw.

[0016] Optionally, the base includes a seat body, an armrest frame, and casters, with the armrest frame positioned above the seat body and the casters positioned below the seat body.

[0017] Optionally, the handrail frame includes two fixed columns and a handrail beam. The bottom end of the fixed column is fixed to the base body, and the handrail beam is connected between the two fixed columns and its height is adjustable.

[0018] Optionally, the building electrical wiring device also includes a guide assembly, which includes a fixing frame. The top of the fixing frame has a notch, and two guide wheels distributed vertically are installed in the notch. The axis of each guide wheel is arranged in the left-right direction. An annular groove is formed on the outer surface of each guide wheel. The annular groove is coaxially arranged with the guide wheel, and the annular grooves of the two guide wheels are connected to form a wire-passing groove.

[0019] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0020] The electrical wiring device for buildings provided by this utility model supports the cable reel through two sets of wiring assembly struts. The distance between the upper and lower struts can be adjusted by moving two movable blocks closer or further apart, allowing the struts to adapt to cable reels with different inner diameters. Simultaneously, the device also has limiting rods on the struts. The movement of the connecting parts can drive the relative movement of two mounting parts, thus limiting the limiting rods of the two wiring assembly sets to the left and right ends of the cable reel. The cooperation between the struts and the limiting rods maintains the stability of the cable reel. When it is necessary to replace the cable reel, controlling the two wiring assembly sets to move further apart allows the cable reel to be installed or removed from the space between the two sets of wiring assembly sets, making the replacement operation relatively convenient.

Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0032] The following is combined Figures 1 to 4 The specific embodiments of this utility model will be described in detail below.

[0033] This embodiment provides a building electrical wiring device, including a base 1 and a wiring rack 2.

[0034] The base 1 is mainly used to provide structural support for the wire feeding frame 2.

[0035] Specifically, such as Figure 1 As shown, the base 1 includes a base body 13, a handrail frame 14, and casters 15. The handrail frame 14 is located above the base body 13, and the casters 15 are located below the base body 13. The handrail frame 14 facilitates the operator to push the entire device forward or backward, and the casters 15 facilitate the movement of the entire device.

[0036] More specifically, the seat body 13 can be plate-shaped, block-shaped, box-shaped, or other shapes, for example... Figure 1 The seat body 13 shown is plate-shaped.

[0037] More specifically, such as Figure 1 As shown, the handrail frame 14 includes two fixed columns 141 and a handrail beam 142. The bottom end of the fixed columns 141 is fixed to the base body, and the handrail beam 142 is connected between the two fixed columns 141 and is height-adjustable. The height-adjustable design of the handrail beam 142 is mainly to facilitate use by operators of different heights.

[0038] Details, such as Figure 1 As shown, the upper end of the fixed column 141 has a vertically arranged strip-shaped hole, and the handrail beam 142 is designed with a U-shaped structure, with a locking screw screw that passes through the strip-shaped hole screwed onto the end of the U-shaped structure. During adjustment, after the handrail beam 142 is adjusted to a suitable height, the locking screw is tightened so that its head presses against the fixed column 141 to fix the handrail beam 142 relative to the fixed column 141.

[0039] Among them, the wire feeding frame 2 is an important part of this device. The wire feeding frame 2 is installed on the base 1. The wire feeding frame 2 is formed by splicing two sets of wire feeding components that are symmetrically distributed on the left and right. The wire feeding components include connector 21, mounting component 22, moving block 23, support rod 24 and limiting rod 25.

[0040] The structure of the wire feeding frame 2 will be described in detail below.

[0041] Connector 21:

[0042] The connector 21 is mounted on the base 1. At least one set of cable feeding assembly connectors 21 is driven to move in the left and right direction, including option one: only one set of cable feeding assembly connectors 21 is driven to move in the left and right direction, and option two: both sets of cable feeding assembly connectors 21 are driven to move in the left and right direction. In use, the movement of one or two connectors 21 increases the distance between the two sets of cable feeding assemblies to form a space, allowing the cable reel 100 to be inserted into or removed from this space.

[0043] Specifically, such as Figure 1 and Figure 2 Both sets of wire feeding assemblies have connectors 21 that can be driven to move in the left and right directions, moving closer to or further away from each other. Compared to solutions where only one connector 21 moves or both connectors 21 move independently, this solution can drive both connectors 21 to move simultaneously, resulting in higher adjustment efficiency.

[0044] More specifically, such as Figure 1 As shown, the base 1 has a strip groove 11 arranged in the left-right direction. A first screw 12 is rotatably installed in the strip groove 11. The first screw 12 has two sections of threads with different directions of rotation. The connecting parts 21 of the two sets of wire feeding assemblies are slidably installed in the strip groove 11 and respectively screwed onto the two sections of threads of the first screw 12. During adjustment, turning the first screw 12 will cause the two connecting parts 21 to move closer or further apart. The structure is simple and the operation is convenient.

[0045] Details, such as Figure 1 As shown, for easy adjustment, one end of the first screw 12 can extend outwards from the base 1, and a handwheel 16 can be installed at this extended end, allowing the first screw 12 to be easily turned manually. It should be noted that... Figure 1The main body of the first screw 12 is obscured by the base 1, and only the aforementioned extended end is visible.

[0046] It should be noted that the driving of the connector 21 is not limited to the manual driving method of this embodiment. It can also be driven by mechanical means such as a motor to drive the first screw 12 to rotate.

[0047] Mounting component 22, movable block 23, and support rod 24:

[0048] Mounting component 22 is fixed above connecting component 21. Two vertically distributed movable blocks 23 are mounted on mounting component 22, and these blocks 23 are driven to move closer or further apart. Each movable block 23 is fixed with a horizontally arranged support rod 24 extending towards another cable feeding assembly. In use, the support rods 24 of both cable feeding assemblies jointly support the cable reel 100, and the movement of the two movable blocks 23 allows for adaptation to cable reels 100 with different inner diameters.

[0049] It is easy to understand that the support rods 24 of the two sets of cable laying components can support the cable reel 100 in a mating contact posture or in a non-contact posture with a gap, as long as the cable reel 100 is securely supported.

[0050] It should be noted that when adjusting the distance between the upper and lower support rods 24, the contact force between the support rods 24 and the inner wall of the cable reel 100 should be appropriate. This will allow the cable reel 100 to reel in and out by rotating, and also ensure the stability of the cable reel 100 installation.

[0051] Specifically, the main shape of the mounting component 22 is not limited; it can be plate-shaped, block-shaped, or other shapes, for example... Figure 1 and Figure 2 The mounting component 22 shown is a plate-shaped structure with the plate surface arranged vertically.

[0052] Specifically, such as Figure 1 and Figure 3 As shown, in each cable laying assembly, a rotating drum 241 is installed on the side of the support rod 24 away from the other support rod 24, and the axis of the rotating drum 241 is arranged in the left-right direction. The support rod 24 contacts the inner wall of the cable reel 100 through the rotating drum 241, which can reduce the friction between the inner wall of the cable reel 100 and the support rod 24 when the cable reel 100 rotates, making the rotation smoother.

[0053] Specifically, such as Figure 1 and Figure 2As shown, mounting component 22 has a groove 221 on its surface facing another mounting component 22. A second screw 222 is rotatably mounted in the groove 221 and a guide post 223 is fixed therein. Both the second screw 222 and the guide post 223 are vertically arranged. The second screw 222 has two threads with different directions of rotation. Two moving blocks 23 located on the same mounting component 22 are slidably fitted onto the guide post 223 and respectively screwed onto the two threads of the second screw 222. During adjustment, by turning the second screw 222, the two moving blocks 23 are driven to move closer or further apart, thereby adjusting the distance between the two moving blocks 23.

[0054] More specifically, such as Figure 2 As shown, each groove 221 is provided with two guide posts 223, and the second screw 222 is arranged between the two guide posts 223, which can make the movement of the moving block 23 more stable.

[0055] More specifically, such as Figure 2 As shown, for easy adjustment, the upper end of the second screw 222 can be extended outward from the mounting part 22, and a knob 224 can be installed at the extended end, so that the second screw 222 can be easily turned manually.

[0056] It should be noted that the driving of the moving block 23 is not limited to the manual driving method of this embodiment. It can also be driven by mechanical means such as a motor to drive the second screw 222 to rotate.

[0057] Limit rod 25:

[0058] The limiting rod 25 is fixed on the support rod 24 and perpendicular to the support rod 24. The limiting rods 25 of the two sets of cable laying assemblies are used to limit the left and right ends of the cable reel 100 respectively.

[0059] It should be noted that since the cable reel 100 needs to rotate during cable laying, the gap between the limit rod 25 and the end of the cable reel 100 should be appropriate to avoid the cable reel 100 being unable to rotate due to excessive contact, and also to avoid the cable reel 100 wobbling from side to side due to excessive gap.

[0060] Specifically, such as Figure 2 and Figure 3 As shown, the limiting rod 25 can slide left and right along the corresponding support rod 24 and is equipped with a locking fastener 26 for fixing the limiting rod 25 to the support rod 24. By adjusting the left and right position of the limiting rod 25 on the support rod 24, the axial dimension range of the cable reel 100 applicable to this device can be expanded, thus broadening its application range.

[0061] More specifically, such as Figure 2 and Figure 3As shown, in each wire feeding assembly, a slide rail 242 is installed on the side of the support rod 24 facing the other support rod 24. The slide rail 242 is arranged in the left-right direction and connected to a slider 243. A limiting rod 25 is fixed on the slider 243 and extends to the front and rear sides of the slider 243. The locking fastener 26 is a fastener screwed onto the slider 243 and abuts against the slide rail 242. During adjustment, first loosen the fastener, then move the slider 243 along with the limiting rod 25 to the appropriate position, and finally tighten the fastener.

[0062] Furthermore, the building electrical wiring device of this embodiment also includes a guide assembly 3. The guide assembly 3 includes a fixing frame 31, and a notch 32 is provided at the top of the fixing frame 31. Two guide wheels 33 are installed in the notch 32, which are arranged vertically. The axis of each guide wheel 33 is arranged in the left-right direction. An annular groove is provided on the outer circumference of each guide wheel 33. The annular groove is coaxially arranged with the guide wheel 33, and the annular grooves of the two guide wheels 33 are connected to form a wire-passing groove 34. In use, the cable of the cable reel 100 is passed through the wire-passing groove 34. When the cable reel 100 is unwound, the friction between the cable and the wire-passing groove 34 drives the two guide wheels 33 to rotate, resulting in low frictional resistance.

[0063] The method of using the building electrical wiring device in this embodiment is as follows:

[0064] S1. By rotating the first screw 12 in the forward direction, the left and right sets of wire feeding assemblies are moved away from each other until there is enough space between the support rods 24 of the two sets of wire feeding assemblies. Then, the cable reel 100 to be installed is placed into the space and moved to the left or right so that the cable reel 100 is fitted onto the support rod 24 of one of the wire feeding assemblies. Then, by rotating the first screw 12 in the reverse direction, the left and right sets of wire feeding assemblies are moved closer to each other until the limiting rods 25 of the two sets of wire feeding assemblies are limited to the left and right ends of the cable reel 100.

[0065] S2. The forward rotation of the second screw 222 causes the upper and lower moving blocks 23 to move away from each other until the rotating cylinder 241 located on the upper and lower support rods 24 respectively abuts against the top and bottom of the inner wall of the cable reel 100.

[0066] S3. Lead the cable from the cable reel 100 out of the cable groove 34, and unwind the cable reel 100 for use;

[0067] S4. When disassembling the cable reel 100, the upper and lower moving blocks 23 should first be brought closer together by the reverse rotation of the second screw 222, and then the left and right cable laying assemblies should be moved away from each other by the forward rotation of the first screw 12 until there is enough space between the support rods 24 of the two cable laying assemblies. Then the cable reel 100 to be disassembled should be taken out from this space.

[0068] The above are merely specific embodiments of this utility model, enabling those skilled in the art to understand or implement this utility model. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
