Description

Technical Field

[0001] This application relates to the technical field of low-voltage electrical conduits, and in particular to concealed fixing devices for low-voltage electrical conduits. Background Technology

[0002] Low-voltage conduit is a type of conduit specifically designed for laying and protecting low-voltage electrical lines. It plays a crucial role in building electrical and intelligent system engineering. It is designed for lines transmitting electrical or electromagnetic signals with relatively low voltage and current, unlike the conduits used for transmitting high-voltage electricity in power systems. Its core function is to provide reliable physical protection for low-voltage lines, preventing mechanical damage during installation, such as compression, cutting, and bending, thus avoiding signal transmission interruptions or quality degradation due to external forces. Simultaneously, low-voltage conduit effectively shields against external electromagnetic interference, reducing interference from electromagnetic fields generated by high-voltage lines or other electronic equipment on low-voltage signals, ensuring the stability and accuracy of signal transmission. This is essential for communication, network, and monitoring systems with extremely high signal quality requirements.

[0003] Traditional concealed fixing devices for low-voltage conduits are not easy to adjust, making them unsuitable for low-voltage conduits of different diameters, resulting in low practicality. Furthermore, the lack of auxiliary structures when fixing the conduits to the wall with screws during installation makes it easy for the screws to shift when tapped, thus presenting certain drawbacks.

[0004] Therefore, in order to solve the above problems, this application provides a concealed fixing device for low-voltage electrical conduits. Utility Model Content

[0005] The purpose of this invention is to provide a concealed fixing device for low-voltage electrical conduits to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a concealed fixing device for low-voltage electrical conduits, including a mounting base, a groove is provided on the outer side of the mounting base, a sliding rod is installed between the inner sidewalls of the groove, sliders are symmetrically installed at both ends of the outer ring surface of the sliding rod, a support frame is installed at one end of the slider, a clamping block is installed at one end of the outer ring surface of the support frame, and a low-voltage electrical conduit is arranged between the inner sidewalls of the clamping blocks.

[0007] Preferably, an adjusting bolt is installed in the groove at the outer end of the mounting base away from the slide groove. One end of the adjusting bolt passes through the interior of the mounting base and is fitted with a disc. The outer ring surface of the adjusting bolt is threadedly connected to the interior of the mounting base.

[0008] Preferably, the outer surface of the disk has two arc-shaped grooves arranged in a ring array, and a cylindrical block is installed at the end of the slider away from the support frame and inside the arc-shaped groove.

[0009] Preferably, the outer ring surface of the slide rod is slidably connected to the interior of the two sliders, and the outer side surface of the slider is in contact with the interior of the groove.

[0010] Preferably, connecting seats are symmetrically installed at both ends of the outer side of the mounting base, and a fixing cone is installed on the connecting seat.

[0011] Preferably, the connecting seat has symmetrically installed auxiliary adhesive at both ends, and the clamping block has an anti-slip pad installed on its inner sidewall.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] This concealed fixing device for low-voltage conduits features a disc that moves with its arc-shaped groove as the disc moves under the influence of the adjusting bolt. This groove exerts a force on the cylindrical block, which is then converted into a force that pushes the slider along the sliding rod. The forward and reverse rotation of the disc allows for precise control of the sliding distance and direction of the two sliders, enabling fine adjustment of the conduit clamping position. This facilitates the limiting and fixing of low-voltage conduits of different diameters. The fixing cone is inserted into a wall or other mounting base, and the friction and anchoring force between the cone and the base firmly fixes the mounting base in its position, providing a stable support foundation for the concealed fixing of the low-voltage conduit. This ensures the device will not loosen or shift during use. When the fixing cone is inserted into the wall, the adhesive helps adhere to the wall surface, providing auxiliary fixing and preventing the mounting base from detaching from the wall when force is applied to the fixing cone, making installation more convenient and practical.

[0019] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0020] Concealed fixing device for low-voltage electrical conduits, refer to Figure 1 - Figure 4 It includes a mounting base 1, a groove 2 is provided on the outer side of the mounting base 1, a slide rod 3 is installed between the inner sidewalls of the groove 2, sliders 4 are symmetrically installed at both ends of the outer ring surface of the slide rod 3, a support frame 5 is installed at one end of the outer side of the slider 4, a clamping block 6 is installed at one end of the outer ring surface of the support frame 5, and a low-voltage conduit 7 is provided between the inner sidewalls of the clamping blocks 6.

[0021] Reference Figure 1 - Figure 4 An adjusting bolt 8 is installed in the groove at the outer end of the mounting base 1 away from the slide groove 2. One end of the adjusting bolt 8 passes through the interior of the mounting base 1 and is fitted with a disc 9. The outer ring surface of the adjusting bolt 8 is threadedly connected to the interior of the mounting base 1. When the position of the slider 4 needs to be adjusted, the adjusting bolt 8 is rotated. Since the adjusting bolt 8 is threadedly connected to the interior of the mounting base 1, rotating the adjusting bolt 8 will cause it to move axially. The movement of the adjusting bolt 8 drives the disc 9 to rotate synchronously.

[0022] Reference Figure 1 - Figure 4 The outer surface of the disc 9 has two arc-shaped grooves 10 arranged in a ring. A cylindrical block 11 is installed on the end of the slider 4 away from the support frame 5 and inside the arc-shaped groove 10. When the disc 9 moves under the action of the adjusting bolt 8, the arc-shaped grooves 10 on it move accordingly. The cylindrical block 11 is fixed on the slider 4 and embedded in the arc-shaped groove 10. When the arc-shaped groove 10 moves, it will exert a force on the cylindrical block 11. Since the cylindrical block 11 can only move under the constraint of the arc-shaped groove 10, and the slider 4 can only slide in a straight line due to the guidance of the sliding rod 3 and the sliding groove 2, the force exerted by the arc-shaped groove 10 on the cylindrical block 11 will be converted into a force that pushes the slider. The force of sliding along the slide bar 3 can be precisely controlled by the forward and reverse rotation of the disc 9 to adjust the sliding distance and direction of the two sliders 4, thereby achieving fine adjustment of the clamping position of the low-voltage conduit 7. This facilitates the limiting and fixing of low-voltage conduits 7 of different diameters. The outer ring surface of the slide bar 3 is slidably connected to the interior of the two sliders 4, and the outer side surface of the slider 4 is in contact with the interior of the groove 2. The sliding connection structure between the slide bar 3 and the slider 4 ensures that the slider 4 can slide smoothly on the slide bar 3. At the same time, the contact design between the outer side surface of the slider 4 and the interior of the groove 2 increases the stability of the sliding and prevents the slider 4 from shaking or shifting during the sliding process.

[0023] Reference Figure 1 - Figure 4The mounting base 1 has symmetrically mounted connecting seats 12 at both ends. A fixing cone 13 is mounted on each connecting seat 12, providing a mounting position for the fixing cone 13. The fixing cone 13 is fixed to the mounting base 1 via the connecting seats 12. When installing the entire fixing device, the fixing cone 13 is inserted into the wall or other mounting base. The friction and anchoring force between the fixing cone 13 and the base securely fixes the mounting base 1 in its mounting position, providing a stable support foundation for the concealed fixing of the low-voltage conduit 7, ensuring that the device will not loosen or shift during use. The connecting seats 12 have symmetrically mounted connecting seats 12 at both ends. The device is equipped with an adhesive 14 and an anti-slip pad 15 on the inner wall of the clamping block 6. The adhesive 14 is installed on both ends of the outer side of the connecting seat 12. When the fixing cone 13 is inserted into the wall, the adhesive 14 adheres to the wall surface to assist in fixing, preventing the mounting seat 1 from detaching from the wall when force is applied to the fixing cone 13, making the installation more convenient. The anti-slip pad 15 on the inner wall of the clamping block 6 can increase the friction between the clamping block 6 and the low-voltage conduit 7 when clamping it, preventing the low-voltage conduit 7 from sliding or falling off when subjected to external force, and ensuring that the low-voltage conduit 7 is stably and reliably fixed between the clamping blocks 6.

[0024] The implementation principle of the concealed fixing device for low-voltage conduits in this application embodiment is as follows: When using this device, when it is necessary to adjust the position of the slider 4, rotate the adjusting bolt 8. Since the adjusting bolt 8 is internally threaded with the mounting base 1, rotating the adjusting bolt 8 will cause it to move axially. The movement of the adjusting bolt 8 drives the disc 9 to rotate synchronously. When the disc 9 moves under the drive of the adjusting bolt 8, the arc groove 10 on it moves accordingly. The cylindrical block 11 is fixed on the slider 4 and embedded in the arc groove 10. When the arc groove 10 moves, it will exert a force on the cylindrical block 11. 1. The slider 4 can only move under the constraint of the arc groove 10, and the slider 4 can only slide in a straight line due to the guidance of the sliding rod 3 and the sliding groove 2. Therefore, the force exerted by the arc groove 10 on the cylindrical block 11 will be converted into a force that pushes the slider 4 to slide along the sliding rod 3. The sliding distance and direction of the two sliders 4 can be precisely controlled by the forward and reverse rotation of the disc 9, so as to achieve fine adjustment of the clamping position of the low-voltage conduit 7, which is convenient for limiting and fixing low-voltage conduits 7 of different diameters. The sliding connection structure between the sliding rod 3 and the slider 4 ensures that the slider 4 can slide smoothly on the sliding rod 3, while the outer surface of the slider 4 The fitted design inside the groove 2 increases sliding stability and prevents the slider 4 from shaking or shifting during sliding. The connecting seat 12 provides an installation position for the fixing cone 13, which is fixed to the mounting base 1 via the connecting seat 12. When installing the entire fixing device, the fixing cone 13 is inserted into the wall or other mounting base. The friction and anchoring force between the fixing cone 13 and the base are used to firmly fix the mounting base 1 in the installation position, providing a stable support foundation for the concealed fixing of the low-voltage conduit 7 and ensuring that the device will not loosen during use. When the fixing cone 13 is inserted into the wall, the auxiliary adhesive 14 adheres to the wall surface to assist in fixing, preventing the mounting base 1 from detaching from the wall when force is applied to the fixing cone 13, making installation more convenient. The anti-slip pad 15 on the inner wall of the clamping block 6 increases the friction between the clamping block 6 and the low-voltage conduit 7 when clamping it, preventing the low-voltage conduit 7 from sliding or falling off when subjected to external force, ensuring that the low-voltage conduit 7 is stably and reliably fixed between the clamping blocks 6. The operation is convenient and the practicality is better. The thread opening angle of the external thread of the adjusting bolt 8 is 20 degrees. The thread self-locking condition needs to meet the following formula calculation: self-locking condition = friction coefficient * tan (helix angle) ≥ 1.
