Description

Technical Field

[0001] This invention relates to the field of electrical conduit equipment, specifically to an integrated connection device for electrical conduits in prefabricated buildings and its installation method. Background Technology

[0002] Prefabricated building electrical quick-installation conduit system is a systematic solution for building electrical systems based on the concept of industrialized production. Its core is to achieve efficient installation and operation and maintenance of electrical conduits through integrated design and standardized processes. This technology is based on existing standards for building electrical design, construction, and acceptance, and integrates the "conduit separation" principle of prefabricated buildings, standardizing and integrating technologies such as distribution boxes, electrical conduits, wires, and electrical accessories.

[0003] The core components of the above system are as follows: Figure 14 The electrical wiring connectors shown are Figure 15 The T-type electrical conduit connector shown is equipped with mating copper wires and copper wire sockets. By interlocking two adjacent standard connectors, the integrated assembly of the electrical conduit system can be quickly achieved. However, some connectors require uninterrupted power connection during connection; direct manual connection poses safety hazards. Therefore, a connection device that eliminates the need for manual connection and is easy to install is required.

[0004] Based on this, the present invention is proposed. Summary of the Invention

[0064] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0065] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0066] like Figure 1As shown, the prefabricated building electrical wiring integrated connection device includes: a base 1, a track 2, a lateral movement mechanism 3, a feeding mechanism 4, a fine-tuning mechanism 5, a locking mechanism 8, and three pipe joint limiting devices. One pipe joint limiting device is installed at the center of the base 1. The track 2 is installed on the base 1 and is arc-shaped, with two arc-shaped grooves corresponding to the shape of the track 2. A sliding rod 202 is slidably installed in the two arc-shaped grooves, and the top of the sliding rod 202 is connected to the lateral movement mechanism 3 through a connecting platform 201. The lateral movement mechanism 3 is installed on the base 1 and is slidably connected to the track 2. The feeding mechanism 4 is installed on the base 1. The fine-tuning mechanism 5 is installed at the top of the feeding mechanism 4. Two pipe joint limiting devices are respectively installed at the top of the lateral movement mechanism 3 and the fine-tuning mechanism 5. The pipe joint limiting device at the top of the lateral movement mechanism 3 is parallel to the pipe joint limiting device at the center of the base 1. The pipe joint limiting device located at the top of the fine-tuning mechanism 5 is perpendicular to the pipe joint limiting device located at the center of the base 1. The pipe joint limiting device can precisely limit the electrical pipe joint, thereby making the electrical pipe joints clamped on the two parallel pipe joint limiting devices coaxial, facilitating docking. The electrical pipe joints clamped on the vertically set pipe joint limiting devices are perpendicular to each other, which facilitates the docking of T-shaped electrical pipe joints.

[0067] refer to Figure 2 , Figure 4 The transverse moving mechanism 3 includes: a turntable 31, a first slide groove 32, a first slider 33, a first lead screw 34, a first moving seat 35, and a second motor 36. The turntable 31 is rotatably mounted on the track 2, and its rotation center is coaxial with the track 2. When the turntable 31 rotates, the slide rod 202 slides in the track 2. Since there are two slide rods 202, the turntable 31 can rotate stably. When the turntable 31 rotates 180 degrees, the pipeline joint limiting device located on the transverse moving mechanism 3 rotates 180 degrees synchronously, which facilitates switching the docking direction of the electrical pipeline joint. The first slide groove 32 is formed on the turntable 31, and the first slider 33 is slidably mounted in the first slide groove 32, with its top end connected to the pipeline joint limiting device, ensuring that the pipeline joint limiting device can be aligned with the axial direction of the first slide groove 32. At the same time, the cross-sections of the first slide groove 32 and the first slider 33 are both dovetail-shaped, ensuring stable sliding while preventing disengagement. The first lead screw 34 is rotatably mounted on the turntable 31. The first movable seat 35 is threadedly connected to the first lead screw 34, and the top of the first movable seat 35 is connected to the pipeline joint limiting device. When the first lead screw 34 rotates, it can ensure that the first movable seat 35 moves along the axial direction of the first lead screw 34. The second motor 36 is mounted on the turntable 31, and its output end is connected to the first lead screw 34. Turning on the second motor 36 can drive the first lead screw 34 to rotate.

[0068] refer to Figure 2, Figure 3 The feeding mechanism 4 includes: a fixed platform 41, a second slide groove 42, a cylinder 43, a second slider 44, a limiting groove 45, and a push block 46. The fixed platform 41 is mounted on the base 1. The second slide groove 42 is formed on the fixed platform 41, and the second slider 44 is slidably mounted in the second slide groove 42. The cross-sections of the second slider 44 and the second slide groove 42 are dovetail-shaped to ensure stable sliding of the fixed platform 41 while preventing it from detaching. The limiting groove 45 is formed on the fixed platform 41, and the push block 46 is slidably mounted in the limiting groove 45. The push block 46 is connected to the fine-tuning mechanism 5. The cylinder 43 is mounted on the fixed platform 41, and its output end is connected to the push block 46. Activating the cylinder 43 can push the push block 46 to move the fine-tuning mechanism 5 along the axial direction of the limiting groove 45.

[0069] refer to Figure 2 The fine-tuning mechanism 5 includes: a fine-tuning seat 51, a third slide 52, a third slider 53, a second moving seat 54, a second lead screw 55, and a knob 56.

[0070] The lower surface of the fine-tuning seat 51 is connected to the second slider 44 and the push block 46. A third slide groove 52 is formed on the fine-tuning seat 51, and the third slider 53 is slidably installed in the third slide groove 52. The top of the third slider 53 is connected to the pipeline joint limiting device. The cross-sections of the third slide groove 52 and the third slider 53 are dovetail-shaped to ensure stable sliding while preventing disengagement. The top of the second movable seat 54 is connected to the pipeline joint limiting device. The second lead screw 55 is rotatably installed on the fine-tuning seat 51, and the second movable seat 54 is threadedly connected to the second lead screw 55. Rotation of the second lead screw 55 allows the second movable seat 54 to drive the pipeline joint limiting device at its top to move along the axial direction of the second lead screw 55. A knob 56 is installed on the fine-tuning seat 51 and connected to the second lead screw 55. Rotating the knob 56 allows the second lead screw 55 to rotate, thereby enabling fine-tuning of the position of the pipeline joint limiting device.

[0071] refer to Figure 2 , Figure 11 , Figure 12 , Figure 13In this embodiment, locking mechanisms 8 are installed at both ends of the track 2. After the lateral moving mechanism 3 rotates 180 degrees, the locking mechanism 8 can lock the slide rod 202 to ensure stable position. The locking mechanism 8 includes: a fixing block 81, a locking block 82, a first connecting post 83, a second connecting post 84, a third spring 85, and a limiting post 86. The fixing block 81 is installed on the side wall of the track 2, and the locking block 82 is rotatably installed on the fixing block 81. The two side walls of the locking block 82 are arranged in a V-shape. The first connecting post 83 and the second connecting post 84 are respectively installed on the locking block 82 and the fixing block 81, and the first connecting post 83 and the second connecting post 84 are distributed on both sides of the rotatable connection between the locking block 82 and the fixing block 81. The third spring 85 is installed between the first connecting post 83 and the second connecting post 84. The third spring 85 is in a stretched state, and the first connecting post 83 is offset from the straight line where the rotatable connection between the locking block 82 and the fixing block 81 and the second connecting post 84 are located. There are two limit posts 86, which are installed on the fixed block 81, and the two limit posts 86 are located on both sides of the locking block 82. The locking block 82 can only rotate between the two limit posts 86. It is worth noting that grooves are machined at both ends of the track 2, and the locking mechanism 8 as a whole does not exceed the upper surface of the track 2 to avoid affecting the rotation of the turntable 31.

[0072] refer to Figure 7 The pipeline joint limiting device includes a first rotation adjustment mechanism 6 and a limiting mechanism 7. The limiting mechanism 7 is mounted on the first rotation adjustment mechanism 6, and the first rotation adjustment mechanism 6 is controlled to adjust the angle of the limiting mechanism 7 in the vertical plane.

[0073] The first rotation adjustment mechanism 6 includes: a stand 61, a guide rail 62, a slot 63, a rack 64, a groove 65, a connecting frame 66, a gear 67, a first motor 68, and a fixing frame 69. The guide rail 62 is mounted on the stand 61 and is arc-shaped, hollow, and slotted towards the center. The slot 63 is formed on the guide rail 62. The rack 64 is slidably mounted in the guide rail 62 and is arc-shaped and coaxial with the guide rail 62. The rack 64 has a groove 65 that slidably engages with the guide rail 62, ensuring stable sliding and preventing derailment. The central angle between the guide rail 62 and the rack 64 is 190-200 degrees, ensuring that the relative rotation range between the rack 64 and the guide rail 62 is not less than 180 degrees. A connecting frame 66 is mounted on a vertical frame 61. A gear 67 is rotatably mounted on the connecting frame 66, and the gear 67 meshes with a rack 64 through a slot 63. Rotation of the gear 67 drives the rack 64 to rotate. A first motor 68 is mounted on the connecting frame 66, and its output end is connected to the gear 67. Turning on the first motor 68 drives the gear 67 to rotate. A fixing frame 69 is mounted on the rack 64, and the fixing frame 69 is fixedly connected to the limiting mechanism 7.

[0074] refer to Figure 8 , Figure 9 , Figure 10 The limiting mechanism 7 includes: a mounting base 71, a rotating arm 72, a limiting wall 72a, a drive base 73, a drive arm 74, a through slot 75, a first spring 76, a drive rod 77, a fixed frame 78, a first mounting rod 79, a second spring 710, a first clamping plate 711, and a second clamping plate 712. The mounting base 71 is U-shaped. There are two rotating arms 72, which are rotatably mounted in the mounting base 71 and are symmetrically arranged. The drive base 73 is mounted in the mounting base 71 and is located between the two rotating arms 72. The drive arms 74 are symmetrically mounted on both sides of the drive base 73. There are four through slots 75, with two through slots 75 forming a group. The two groups of through slots 75 are respectively opened on the two side walls of the mounting base 71, and the drive arm 74 passes through the through slot 75. Limiting walls 72a are respectively provided on the opposite sides of the two rotating arms 72, and the limiting walls 72a are in contact with the drive arms 74. The limiting effect of the drive arms 74 prevents the rotating arms 72 from rotating. The first spring 76 is installed between the drive arm 74 and the inner wall of the through groove 75. When the drive seat 73 and the drive arm 74 move downwards, they can compress the first spring 76. After the external force is removed, the drive seat 73 is reset by the elastic force of the first spring 76. The drive rod 77 is installed at the top of the drive seat 73. There are two fixed frames 78, which are symmetrically installed on both sides of the mounting base 71. There are four first mounting rods 79, which are installed on the two fixed frames 78 and the two rotating arms 72 respectively. The second spring 710 is installed between the rotating arm 72 and the fixed frame 78, and its two ends are connected to the two first mounting rods 79 respectively. The second spring 710 is in a stretched state, which, together with the restraint of the drive arm 74, ensures the stability of the rotating arm 72 and prevents rotation. The first clamping plate 711 and the second clamping plate 712 are respectively installed on the top of the opposite side of the two rotating arms 72. The first clamping plate 711 is arc-shaped and can clamp electrical cable connectors in conjunction with the second clamping plate 712. The first clamping plate 711 is divided into two parts, and there is a gap between the two first clamping plates 711. When clamping T-shaped electrical cable connectors, this gap can avoid branch pipes and ensure stable clamping.

[0075] Furthermore, embodiments of the present invention also provide an integrated connection method for electrical wiring in prefabricated buildings, comprising the following steps:

[0076] Step 1: Rotate the turntable 31 to select its position relative to the pipeline joint limiting device located at the center of the base 1 during operation. When the slide rod 202 touches the locking block 82, it can be rotated, and at the same time, the third spring 85 is further stretched. When the first connecting column 83 passes the straight line where the locking block 82 and the fixed block 81 are rotated and the second connecting column 84 are located, the inner wall of the locking block 82 is attached to the slide rod 202. At this time, the limiting force of the locking block 82 and the tension of the third spring 85 are used to limit the slide rod 202, thereby achieving the positioning of the turntable 31.

[0077] Step 2: Rotate knob 56 to make the second lead screw 55 rotate, which drives the second movable seat 54 to move and adjust the limit device of the pipeline joint connected to it.

[0078] Step 3: Place the electrical cable connector between the two rotating arms 72, press the drive rod 77 to move the drive seat 73 and the drive arm 74, and compress the first spring 76 at the same time. When the drive arm 74 leaves the limiting wall 72a, the two rotating arms 72 rotate relative to each other by the tension of the second spring 710, and the electrical cable connector is clamped by the first clamping plate 711 and the second clamping plate 712.

[0079] Step 4: If the copper wire interfaces in the two electrical conduit connectors do not correspond, turn on the first motor 68 to drive the gear 67 to rotate, and drive the rack 64 to rotate, thereby adjusting the angle of the clamped electrical conduit connector.

[0080] Step 5: Turn on the second motor 36 to drive the first lead screw 34 to rotate, and then use the first moving seat 35 to drive the pipeline joint limiting device at its top to move towards the pipeline joint limiting device located in the center of the base 1, so as to complete the connection of the electrical pipeline joint.

[0081] Step 6: When connecting the T-type electrical conduit branch pipe joint, activate cylinder 43 to drive push block 46 to move fine adjustment seat 51 toward the conduit joint limiting device located in the center of base 1, thus completing the connection of the electrical conduit joint.

[0082] Step 7: Pull the electrical cable away from the mounting base 71 to expand the two rotating arms 72 and disengage the electrical cable connector.
