Description

Technical Field

[0001] This utility model specifically relates to a multi-wire conduit pre-installation component, belonging to the field of building electrical systems. Background Technology

[0002] Electrical wiring installation is a crucial step in electrical engineering, and the process must strictly adhere to specifications to ensure the safety and reliability of the wiring. Before construction, personnel must familiarize themselves with the drawings and undergo technical briefings, clarifying requirements such as wiring routes, conductor specifications, and laying methods. Simultaneously, prepare conductors, auxiliary materials (such as galvanized iron wire, protective sleeves, insulating tape, etc.) and tools (such as wire strippers, multimeters, etc.), and check that the conduits are unobstructed and the environment meets requirements, ensuring a safe and clean construction site.

[0003] The construction process mainly includes steps such as selecting conductors, threading the conductor strip, cleaning the conduit, installing protective sleeves, laying and cutting the conductor, binding the conductor and the conductor strip, threading the conductor into the conduit, connecting the conductors, wrapping the joints, and inspecting the line and testing insulation resistance. First, select conductors of appropriate specifications and models according to design requirements, and use different colors to distinguish their uses. Next, prepare and thread the conductor strip, bind it with cloth strips, remove debris from the conduit, and install protective sleeves at the conduit openings to prevent damage to the conductors. When laying the conductors, avoid tight knots or tangles, and leave sufficient length as needed. The conductor and conductor strip should be securely bound, forming a smooth transition for easy threading. When threading, talcum powder can be blown into the conduit to reduce friction. Two people should work together to complete the operation. It is important to note that conductors of different circuits and voltage levels must not be threaded into the same conduit, and conductors of the same AC circuit must be threaded into the same steel conduit. The total cross-sectional area of ​​the conductors in the conduit must not exceed 40% of the open cross-sectional area of ​​the conduit. When connecting wires, select an appropriate connection method based on the wire cross-sectional area, such as crimping, welding, or wrapping, to ensure a firm connection, good contact, and no looseness or gaps. The connection should be smooth and burr-free, and proper insulation should be applied. After the wiring is laid, a comprehensive inspection is required to ensure that the wires are laid straight, without kinks, firmly connected, and that the insulation layer is undamaged. Simultaneously, use a megohmmeter to test the insulation resistance of the wiring to ensure it meets design requirements.

[0004] In actual wiring operations, there are two construction methods: one is to pre-bury the conduit in the wall and then thread the wires through the conduit; the other is to thread the wires through the conduit in advance and then bury them in the wall.

[0005] Regardless of which construction method is used, the following problems exist:

[0006] When too many wires are inserted into a single conduit at once, the wires do not have a fixed trajectory within the conduit. Instead, they intertwine with each other as they are inserted, especially when there are bends in the wires. As the wire insertion process continues, the resistance to insertion gradually increases, and in severe cases, the insertion process may become impossible to continue.

[0007] The wiring was completed, but there were cases of missing wires or temporary additions. As a result, the conduit, which already contained multiple wires, did not have enough space to run the wires. The existing wires had to be pulled out, and the additional wires had to be re-threaded, which extended the construction period and was time-consuming and labor-intensive.

[0008] In summary, the current process of threading multiple electrical wires involves separate threading and securing, making it difficult to standardize the process and preventing the addition of wires after the initial threading. Utility Model Content

[0009] To overcome the shortcomings of existing technologies, a multi-wire conduit pre-installation component is provided to solve the above problems.

[0010] A multi-wire conduit pre-reservation component includes a main support disk and multiple balls. The main support disk is a circular disk body. Multiple wire-holding grooves and multiple spherical grooves are alternately machined on the outer wall of the main support disk along its circumference. A ball is slidably disposed in each spherical groove. The main support disk is pre-reserved holes machined along its thickness direction.

[0011] As a preferred embodiment: a flexible pad is provided in each wire slot. The flexible pad is an arc-shaped sheet. The outer wall of each flexible pad is attached to the inner wall of its corresponding wire slot. The inner wall of each flexible pad is provided with a concave-convex connection part.

[0012] As a preferred option: the spherical groove is replaced with a through groove. The outer wall of the main support plate is alternately machined with multiple wire-clamping grooves and multiple through grooves along its circumference. The length direction of the through groove is the same as the thickness direction of the main support plate. A movable roller is hinged in each through groove. The rolling direction of the roller is the same as the thickness direction of the main support plate.

[0013] As a preferred option, each movable roller is fitted with a flexible elastic sleeve, and the outer wall of the flexible elastic sleeve is machined with several grooves.

[0014] As a preferred embodiment: Multiple T-shaped arc grooves are machined along the circumference of one side of the main support plate. These T-shaped arc grooves are fitted with a limiting component, which includes a circular ring, multiple locking pieces, multiple strip-shaped pads, multiple T-shaped slides, and multiple elastic levers. The circular ring is coaxially aligned with the main support plate. Multiple locking pieces are arranged along the circumference of the circular ring, each corresponding to a locking groove. Multiple T-shaped slides are arranged along the circumference of the side of the circular ring facing the main support plate. Each T-shaped slide is located between two adjacent locking pieces, and each T-shaped slide corresponds to a T-shaped arc groove. Each T-shaped slide slides within its corresponding T-shaped arc groove. An elastic lever is located on one side of each T-shaped slide, and each elastic lever is within its corresponding T-shaped arc groove.

[0015] As a preferred option, the limiting component also includes multiple strip-shaped gaskets, each of which is an annular piece with a notch, and a strip-shaped gasket is correspondingly provided on the inner wall of each piece.

[0016] As a preferred embodiment: an inner cylinder is provided between the limiting component and the main support plate. The inner cylinder includes a main cylinder and a conical sleeve. The main cylinder is provided between the annular plate and the reserved hole. The outer wall of the main cylinder is tightly attached to the inner wall of the annular plate and the inner wall of the reserved hole, respectively. The small end of the main conical sleeve is integrally connected to one end of the main cylinder. The large end of the conical sleeve is machined with multiple circular notches along its circumference. The multiple circular notches are correspondingly set with multiple wire clamping grooves.

[0017] As a preferred embodiment: the inner wall of the reserved hole is provided with multiple inner clamps along its circumference. Each inner clamp is a circular sleeve. Each circular sleeve has a notch processed on it. The notch is connected to the interior of the circular sleeve. Each notch is oriented towards the central axial direction of the reserved hole.

[0018] The beneficial effects of this utility model are as follows:

[0019] The ends of multiple wires are sequentially inserted into the wire slots along the circumference of the main support plate, forming a cylindrical shape. This ensures that the movement trajectory of the wires within the conduit remains unchanged during the threading process, preventing the ends of the wires from intertwining and obstructing the threading. During threading, ball bearings allow for smooth movement within the conduit, while sufficient space is provided in the center area for secondary threading. In summary, this invention achieves standardized threading of multiple wires through the cooperation of the main support plate and multiple ball bearings, improving the standardization and uniformity of the wire arrangement and providing a standardized method for adding wires later.

[0032] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0033] Specific implementation method one: Combining Figure 1 , Figure 2 , Figure 3 , Figure 4, Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 This embodiment describes a multi-wire conduit pre-installation component comprising a main support disk 1 and multiple ball bearings 2. The main support disk 1 is a circular disk. The outer wall of the main support disk 1 is alternately machined with multiple wire-holding grooves 1-1 and multiple spherical grooves 1-2 along its circumference. The opening edge of each wire-holding groove 1-1 is machined to be rounded to prevent the wire 8 from being damaged by the sharp edge when it is pressed into the wire-holding groove 1-1. A ball bearing 2 is slidably disposed in each spherical groove 1-2. The main support disk 1 is machined with pre-drilled holes 1-3 along its thickness direction.

[0034] Multiple ball bearings 2 arranged circumferentially on the main support plate 1 contact the inner wall of the conduit 7, increasing the smoothness of the movement of the present invention within the conduit 7. Meanwhile, multiple wires 8 are evenly distributed at the edge of the main support plate 1, meaning that multiple wires 8 are close to the inner wall of the conduit 7. When it is necessary to add wires 8, the reserved holes 1-3 can provide sufficient space for the added wires 8 to pass through.

[0035] This utility model can also be used in multiple ways simultaneously. Multiple wires 8 are sequentially inserted into the wire slots 1-1, forming a state in which multiple wires 8 wrap around this utility model. At the same time, multiple utility models are installed on multiple wires 8 along the length direction of multiple wires 8, so that multiple wires 8 form a cylindrical structure. At this time, when multiple wires 8 are threaded into the conduit 7, the multiple wires 8 are evenly distributed in the conduit 7, which not only improves the standardization of the threading operation, but also leaves better threading space for subsequent wire additions.

[0036] Specific Implementation Method Two: This implementation method is a further limitation of Specific Implementation Method One. Each wire slot 1-1 is provided with a flexible pad 3. The flexible pad 3 is an arc-shaped sheet. The outer wall of each flexible pad 3 is attached to the inner wall of its corresponding wire slot 1-1. The inner wall of each flexible pad 3 is provided with a concave-convex connection part.

[0037] The wire 8 enters the wire slot 1-1 and comes into contact with the flexible pad 3. The flexible pad 3 uses its elasticity to better wrap and hold the wire 8. At the same time, the concave and convex connecting parts provided on the flexible pad 3 can prevent the wire 8 from coming out of the present invention during the insertion process.

[0038] Specific Implementation Method 3: This implementation method is a further limitation of Specific Implementation Method 1. The spherical groove 1-2 is replaced with a through groove 1-4. The outer wall of the main support disk 1 is alternately machined with multiple wire-clamping grooves 1-1 and multiple through grooves 1-4 along its circumference. The length direction of the through groove 1-4 is in the same direction as the thickness direction of the main support disk 1. A movable roller 5 is hinged in each through groove 1-4. The rolling direction of the roller 5 is in the same direction as the thickness direction of the main support disk 1.

[0039] Multiple movable rollers 5, which are circumferentially hinged on the wire slot 1-1, can improve the smoothness of the movement of this utility model within the wire tube 7.

[0040] Specific implementation method four: This implementation method is a further limitation of specific implementation method three. Each movable roller 5 is fitted with a flexible elastic sleeve 5-1, and several grooves 5-2 are machined on the outer wall of the flexible elastic sleeve 5-1.

[0041] The grooves 5-2 machined on the flexible elastic sleeve 5-1 can generate better friction with the inner wall of the conduit 7, increasing the smoothness of the utility model's movement within the conduit 7.

[0042] Specific Implementation Method Five: This implementation method further defines Specific Implementation Method One. Multiple T-shaped arc grooves 1-5 are machined along the circumference of one side of the main support disk 1. These multiple T-shaped arc grooves 1-5 are fitted with a limiting component 6. The limiting component 6 and the main support disk 1 increase the overall thickness of this utility model, preventing tilting when the main support disk 1 moves within the conduit 7. The limiting component 6 includes a circular ring 6-1, multiple locking pieces 6-2, multiple strip-shaped pads 6-3, multiple T-shaped sliding pieces 6-4, and multiple elastic levers 6-5. The circular ring 6-1 is coaxially arranged with the main support disk 1. The circular ring 6-1... Multiple locking pieces 6-2 are arranged along its circumference, and the multiple locking pieces 6-2 are arranged one-to-one with multiple locking grooves 1-1. Multiple T-shaped sliders 6-4 are arranged along its circumference on the side of the annular piece 6-1 facing the main support plate 1. Each T-shaped slider 6-4 is located between two adjacent locking pieces 6-2. The T-shaped sliders 6-4 are arranged one-to-one with T-shaped arc grooves 1-5. Each T-shaped slider 6-4 is slidably arranged in its corresponding T-shaped arc groove 1-5. A spring-loaded lever 6-5 is arranged on one side of each T-shaped slider 6-4. Each spring-loaded lever 6-5 is arranged in its corresponding T-shaped arc groove 1-5.

[0043] The clip 6-2 pushes the annular piece 6-1 to rotate along its circumference, so that the clip 6-2 and the wire slot 1-1 are completely aligned. At this time, the T-shaped slider 6-4 is in the state of squeezing the elastic lever 6-5. Then, the wire 8 is inserted into the clip 6-2 and the wire slot 1-1 in sequence. The strip-shaped pad 6-3 increases the firmness of the wire 8 in the clip 6-2. Since the squeezed elastic lever 6-5 always applies force to the T-shaped slider 6-4, the annular piece 6-1 drives the clip 6-2 to apply lateral pressure to the wire 8, which strengthens the firmness of the wire 8 in the clip 6-2 and the wire slot 1-1 and prevents the wire 8 from coming off during the wire pulling process.

[0044] Specific Implementation Method Six: This implementation method is a further limitation of Specific Implementation Method Five. The limiting component 6 also includes multiple strip-shaped pads 6-3. Each clip 6-2 is an annular piece with a notch. A strip-shaped pad 6-3 is correspondingly provided on the inner wall of each clip 6-2. The strip-shaped pad 6-3 increases the friction with the wire 8 and prevents the wire 8 from detaching.

[0045] Specific Implementation Method Seven: This implementation method is a further limitation of Specific Implementation Method Five or Six. An inner cylinder 4 is provided between the limiting component 6 and the main support plate 1. The inner cylinder 4 includes a main cylinder body 4-1 and a conical sleeve body 4-2. The main cylinder body 4-1 is provided between the annular piece 6-1 and the reserved hole 1-3. The outer wall of the main cylinder body 4-1 is close to the inner wall of the annular piece 6-1 and the inner wall of the reserved hole 1-3 respectively. The small end of the main conical sleeve body 4-2 is integrally connected to one end of the main cylinder body 4-1. The large end of the conical sleeve body 4-2 is processed with multiple circular notches 4-2-1 along its circumference. The multiple circular notches 4-2-1 are correspondingly provided with multiple wire clamping grooves 1-1.

[0046] The main cylinder 4-1 is inserted sequentially into the annular plate 6-1 and the pre-drilled hole 1-3, so that the outer wall of the main cylinder 4-1 is against the inner wall of the annular plate 6-1 and the inner wall of the pre-drilled hole 1-3, thereby fixing the inner cylinder 4 onto the limiting component 6 and the main support plate 1. Each circular notch 4-2-1 machined on the conical sleeve 4-2 wraps around each wire 8 installed in the clamp 6-2 and the wire slot 1-1. At this time, with the main support plate 1 as the head and the inner cylinder 4 as the tail, the wire threading operation is carried out. After completion, when additional wires are needed, the wire entry point can be located in the direction of the conical sleeve 4-2. Since the conical sleeve 4-2 is flared, it can wrap around the other structures behind it, which can prevent the end of the wire 8 from being inserted into the gap between the limiting component 6 and the main support plate 1 when adding wires, thus preventing the wire threading operation from continuing. Moreover, since the conical sleeve 4-2 is flared, it can also better guide the inserted wire 8 to pass smoothly through the main cylinder 4-1.

[0047] Specific Implementation Method Eight: This implementation method is a further limitation of Specific Implementation Method One. Multiple inner clips 9 are provided on the inner wall of the reserved hole 1-3 along its circumferential direction. Each inner clip 9 is a circular sleeve. Each circular sleeve has a notch processed on it. The notch is connected to the interior of the circular sleeve. Each notch is set towards the central axial direction of the reserved hole 1-3.

[0048] By adding multiple internal clips 9, this utility model can arrange more wires 8 at one time, making more reasonable use of the internal space of the conduit 7. At the same time, the central area inside the conduit 7 still retains a certain amount of space, which can be used for secondary additional wiring of a small number of wires 8.

[0049] The ends of multiple wires 8 are sequentially inserted into the wire slots 1-1, forming a state in which multiple wires 8 wrap around the present invention. Since the positions of the ends of multiple wires 8 are fixed, the ends of multiple wires 8 will not intertwine during the wire threading process, thus avoiding increasing the resistance during the wire threading process. Then, the wires 8 are threaded into the conduit 7, and the ball bearing 2 contacts the inner wall of the conduit 7. As the wires are continuously threaded, the ball bearing 2 acts as a moving wheel to complete the standardized assembly process of the wire threading operation, improving the performance of rapid assembly. Utilizing the free rolling characteristic of the ball bearing 2, the ball bearing 2 can adapt to the threading of wires 8 from all directions. As the wires 8 are continuously extended, when encountering situations where additional wires are added or fewer wires are needed, since the present invention distributes the initially added wires 8 around the inner wall of the conduit 7, there is still wire threading space in the central area of ​​the conduit 7. The second wires 8 can be threaded through the reserved holes 1-3 to achieve the purpose of secondary standardized wire addition.
