Description

Technical Field

[0001] This utility model is an electrical wiring device, belonging to the field of building electrical engineering. Background Technology

[0002] During construction, conduits are often pre-embedded in the walls or grooves are cut into the walls. Mortar is then used to bury the conduits within these grooves. When threading wires through these conduits, the coiled wires need to be restrained to prevent them from unraveling. Since multiple wires need to pass through the conduit together, an electrician's cable release device is used to restrain these coils. The coils are placed on a support shaft on the device. When the wire ends are pulled, the coils rotate around the support shaft, facilitating their unfolding. Because multiple wires are pulled simultaneously, uneven stress can occur, resulting in varying lengths of wire unfolded from the coils. This leads to excess wire outside the cable release device, which can cause tangling and affect threading efficiency. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an electrical wiring device to solve the problems mentioned in the background technology. This utility model enables multiple coiled wires to rotate synchronously, preventing redundant wires from accumulating on the outside of the electrician's wire laying frame due to the excessive length of one or more wires.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an electrical wiring device includes a base frame, which is U-shaped. Two symmetrically arranged U-shaped tubes are mounted on the upper surface of the base frame. A base plate is mounted on the upper surface of the base frame between the two U-shaped tubes. Inclined tubes are installed on the upper surface of the base plate away from the openings of the U-shaped tubes and between the two U-shaped tubes. The upper ends of the inclined tubes on the base plate slidably contact hollow tubes. The two ends of the hollow tubes are rotatably connected to the two U-shaped tubes respectively. Multiple wire-passing holes are evenly distributed on the outer surface of the hollow tubes. A clamping frame is installed in the middle of the inclined tubes. A first clamping plate and a second clamping plate are provided between two connected inclined tubes. The two clamping plates have an inner cylinder installed at the center of the side of the first clamping plate facing the second clamping plate, and an outer cylinder for supporting the coiled wire installed at the center of the side of the second clamping plate facing the first clamping plate. The inner cylinder is inserted into the outer cylinder. Both U-shaped tubes have bushings installed on opposite sides of their inclined tubes. A crank handle is inserted into the bushing and connected to it. A rectangular rod is fixed to one end of the crank handle near the bushing. A shaft head is fixed to the center of the side of the first clamping plate facing away from the second clamping plate and the center of the side of the second clamping plate facing away from the first clamping plate. The shaft head is inserted into a retaining frame. A rectangular hole is opened at the center of one side of the shaft head to cooperate with the rectangular rod. The rectangular rod passes through the rectangular hole.

[0005] Furthermore, a U-shaped plate is installed at the lower part of the bottom frame, with the open end of the U-shaped plate facing the same direction as the open end of the bottom frame, and a drawer box is inserted into the space formed by the U-shaped plate, the bottom plate, and the bottom frame.

[0006] Furthermore, both ends of the hollow tube are connected and fixed with column heads, and a tube sleeve is fitted on the column head, which is connected and fixed to the U-shaped tube.

[0007] Furthermore, a limiting rod is provided on the upper side of the first clamping plate. The two ends of the limiting rod are connected to two U-shaped tubes respectively by screws. The limiting rod is arranged parallel to the hollow tube.

[0008] Furthermore, the limiting rod is provided with a reinforcing rib on the side away from the hollow tube, and the two ends of the reinforcing rib are respectively connected and fixed to two U-shaped tubes. The reinforcing rib is arranged parallel to the hollow tube.

[0009] Furthermore, a positioning plate is fitted onto one end of the rectangular rod near the crank handle and is fixed to the rectangular rod. An annular groove is machined on the annular side of the positioning plate. The positioning plate is inserted into the bushing. A pin hole that matches the annular groove is opened on the outer surface of the bushing. A positioning pin is inserted into the pin hole and is inserted into the annular groove.

[0010] The beneficial effects of this utility model are:

[0011] 1. Place the coiled wire onto the outer cylinder, and then insert the inner cylinder onto the outer cylinder. At this time, the first clamp and the second clamp together restrict the position of the coiled wire. Insert the shaft head on the first clamp and the shaft head on the second clamp into the corresponding clip frame to restrict the position of the coiled wire. Use screws to install the limiting rod between the two U-shaped tubes to facilitate the restriction of the position of the first clamp and the second clamp.

[0012] 2. Insert the prongs at both ends of the hollow tube into the sleeves on the two U-shaped tubes respectively, so as to realize the rotational connection between the hollow tube and the U-shaped tube. This allows the wire end to pass through the wire hole. When the wire is pulled, the wire will drive the prongs to rotate in the sleeve through the hollow tube, which makes it easy to adjust the orientation of the wire hole.

[0013] 3. After the structure formed by multiple sets of first and second clamping plates is confined between two U-shaped tubes, the rectangular rod passes through the rectangular holes on the shaft heads of multiple first and second clamping plates. The rectangular rod and the rectangular holes cooperate with each other, which facilitates the synchronous rotation of the structure formed by multiple sets of first and second clamping plates. This prevents redundant wires from accumulating on the outside of the electrician's cable laying frame due to the long unfolded length of one or more wires.

[0014] 4. Insert the positioning plate into the bushing, and then insert the positioning pin into the channel formed by the pin hole and the annular groove. In this way, the positioning pin can restrict the position of the rectangular rod without affecting the rotation of the positioning plate in the bushing, thus preventing the rectangular rod from moving randomly.

[0015] 5. Fill the drawer box with weights, and then place the drawer box in the space formed by the U-shaped plate, the bottom plate and the bottom frame. This will improve the stability of the electrical cable laying frame formed by the U-shaped tube, the bottom frame and other components, and prevent the electrical cable laying frame formed by the U-shaped tube, the bottom frame and other components from tipping over due to pulling the wires.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please see Figure 1 , Figure 3 and Figure 4 This utility model provides a technical solution: an electrical wiring device, including a U-shaped base frame 1, with two symmetrically arranged U-shaped tubes 3 mounted on the upper surface of the base frame 1, and a base plate 11 positioned between the two U-shaped tubes 3 mounted on the upper surface of the base frame 1. Inclined tubes 13 are installed on the upper surface of the base plate 11, away from the opening of the U-shaped tubes 3 and between the two U-shaped tubes 3. Hollow tubes 9 are slidably contacted at their upper ends on the inclined tubes 13 on the base plate 11, and the two ends of the hollow tubes 9 are rotatably connected to the two U-shaped tubes 3 respectively. Multiple wire-passing holes 10 are evenly provided on the outer surface of the hollow tube 9. Both ends of the hollow tube 9 are connected and fixed with a post head. A sleeve 17 is fitted on the post head. The sleeve 17 is connected and fixed to the U-shaped tube 3, so that the post heads at both ends of the hollow tube 9 are respectively inserted into the sleeve 17 on the two U-shaped tubes 3, realizing the rotational connection between the hollow tube 9 and the U-shaped tube 3, so that the wire end passes through the wire-passing hole 10. Then, when the wire is pulled, the wire will drive the post head to rotate in the sleeve 17 through the hollow tube 9, thereby facilitating the adjustment of the orientation of the wire-passing hole 10.

[0027] See Figures 1-6 A clamping frame 14 is installed in the middle of the inclined tube 13. A first clamping plate 6 and a second clamping plate 8 are provided between the two connected inclined tubes 13. An inner cylinder 22 is installed in the middle of the side of the first clamping plate 6 facing the second clamping plate 8. An outer cylinder 7 for supporting the coiled wire is installed in the middle of the side of the second clamping plate 8 facing the first clamping plate 6. The inner cylinder 22 is inserted into the outer cylinder 7. A shaft head 20 is fixedly connected to the middle of the side of the first clamping plate 6 away from the second clamping plate 8 and the middle of the side of the second clamping plate 8 away from the first clamping plate 6. The shaft head 20 is inserted into the clamping frame 14. A limiting rod 5 is provided on the upper side of the first clamping plate 6. The two ends of the limiting rod 5 are connected to the two U-shaped tubes 3 by screws respectively. The positioning rod 5 is arranged parallel to the hollow tube 9. The side of the positioning rod 5 away from the hollow tube 9 is provided with a reinforcing rib 4. The two ends of the reinforcing rib 4 are respectively connected and fixed to two U-shaped tubes 3. The reinforcing rib 4 is arranged parallel to the hollow tube 9 so that the coiled wire is sleeved on the outer cylinder 7. Then the inner cylinder 22 is inserted into the outer cylinder 7. At this time, the first clamping plate 6 and the second clamping plate 8 together play the role of limiting the position of the coiled wire, so that the shaft head 20 on the first clamping plate 6 and the shaft head 20 on the second clamping plate 8 are respectively inserted into the corresponding clamping frame 14, thus completing the limitation of the position of the coiled wire. The positioning rod 5 is installed between the two U-shaped tubes 3 with screws to facilitate the limitation of the position of the first clamping plate 6 and the second clamping plate 8.

[0028] See Figures 1-7Both U-shaped tubes 3 have inclined tubes 13 with bushings 15 installed on their opposite sides. A rocker handle 2 is inserted into the bushing 15 and connected to it. A rectangular rod 23 is fixedly connected to one end of the rocker handle 2 near the bushing 15. A positioning plate 19 is fitted onto the other end of the rectangular rod 23 near the rocker handle 2 and is fixedly connected to it. An annular groove is machined on the annular side of the positioning plate 19. The positioning plate 19 is inserted into the bushing 15. A pin hole that matches the annular groove is opened on the outer surface of the bushing 15. A positioning pin 16 is inserted into the pin hole and inserted into the annular groove, so that the positioning plate 19 is inserted into the bushing 15. Then, the positioning pin 16 is inserted into the channel formed by the pin hole and the annular groove. Thus, the positioning pin 16 restricts the position of the rectangular rod 23 without affecting the rotation of the positioning plate 19 in the bushing 15, preventing the rectangular rod 23 from moving randomly.

[0029] See Figures 1-7 A rectangular hole 21 is provided in the middle of one side of the shaft head 20 to cooperate with the rectangular rod 23. After the structure formed by multiple sets of first clamping plates 6 and second clamping plates 8 is restricted between two U-shaped tubes 3, the rectangular rod 23 passes through the rectangular hole 21 on the shaft head 20 of multiple first clamping plates 6 and multiple second clamping plates 8. Then the rectangular rod 23 and the rectangular hole 21 cooperate with each other, which makes it easy for the structure formed by multiple sets of first clamping plates 6 and second clamping plates 8 to rotate synchronously, and prevents redundant wires from accumulating on the outside of the electrician's cable laying frame due to the long unfolded length of one or more wires.

[0030] See Figure 1 , Figure 3 and Figure 4 A U-shaped plate 18 is installed at the lower part of the bottom frame 1. The opening end of the U-shaped plate 18 faces the same direction as the opening end of the bottom frame 1. A drawer box 12 is inserted into the space formed by the U-shaped plate 18, the bottom plate 11 and the bottom frame 1. A weight is filled into the drawer box 12 and then the drawer box 12 is inserted into the space formed by the U-shaped plate 18, the bottom plate 11 and the bottom frame 1. This improves the stability of the electrical cable laying frame formed by the U-shaped tube 3, the bottom frame 1 and other components, and prevents the electrical cable laying frame formed by the U-shaped tube 3, the bottom frame 1 and other components from tipping over due to pulling the wires.
