Description

Technical Field

[0001] This utility model relates to the field of conduit fixing technology, and in particular to a fixing device for installing conduits in low-voltage engineering. Background Technology

[0002] In the field of power applications, based on the strength of power transmission, electricity can be clearly divided into two major categories: high-voltage and low-voltage. As an important branch of power applications, low-voltage engineering does not primarily provide large-scale electrical energy directly, but rather focuses on the precise conversion of electrical energy into other forms of energy to meet diverse needs such as information transmission and intelligent control. It plays an indispensable role in many fields of modern society, including communication, security, and automation control.

[0003] In the actual construction of low-voltage electrical projects, the pre-laying of conduits is a crucial step when outdoor wiring is involved. Conduits not only provide necessary physical protection for the wires, preventing them from being corroded, damaged, or accidentally injured by the external environment, but also help to organize and standardize the wiring, making the overall layout more rational and orderly, facilitating subsequent maintenance and management. However, how to securely fix the conduits in their designated locations during installation has always been a critical issue that needs to be addressed during construction.

[0004] Currently, although some conduit fixing devices and related construction methods exist on the market, they still reveal many shortcomings in practical applications. For example, existing fixing methods lack sufficient flexibility and adaptability when facing walls of different materials. For concrete walls, traditional fixing methods often require cumbersome steps such as drilling and installing expansion bolts, which is not only inefficient but also generates dust and noise during drilling, negatively impacting the construction environment. Furthermore, the installation quality of expansion bolts is affected by various factors such as wall material and drilling accuracy; improper installation can easily lead to insecure conduit fixing and potential safety hazards.

[0005] For metal walls, existing fixing devices fail to fully utilize the properties of the metal material. In most cases, fixing methods similar to those used for concrete walls are still required, failing to take advantage of the magnetic adhesion of metal walls. This not only increases construction costs and difficulty but also reduces construction efficiency. Furthermore, existing conduit fixing devices are often structurally simple, lacking modularity and versatility, making it difficult to meet the needs of different conduit sizes and complex construction scenarios, further limiting their widespread application in low-voltage engineering.

[0006] In summary, existing methods and devices for fixing conduits in low-voltage electrical engineering have significant shortcomings in terms of adaptability to different wall materials, construction efficiency, fixing stability, and versatility, failing to meet the requirements of rapid, efficient, and safe construction in modern low-voltage electrical engineering. Therefore, developing a new type of conduit fixing device for low-voltage electrical engineering is of significant practical importance. Utility Model Content

[0007] In response to the above situation and to overcome the shortcomings of the existing technology, this utility model provides a fixing device for installing conduit in low-voltage engineering. This design effectively solves the problems of existing conduit fixing methods and devices in low-voltage engineering lacking flexibility and versatility when adapting to different wall materials, having low construction efficiency, poor fixing stability, and failing to fully utilize the characteristics of metal walls, thus failing to meet the requirements of fast, efficient and safe construction in modern low-voltage engineering.

[0008] To achieve the above objectives, this utility model provides the following technical solution: This utility model includes a base, an expansion screw inside the base, a detachable limiting ring at the top of the base, and a locking assembly on the outer bottom of the limiting ring. The locking assembly includes two connecting blocks, which are arranged symmetrically about the center line of the base. The inner side of each connecting block is connected to the base. A limiting plate is provided inside each connecting block, and a cylindrical rod is provided on the inner side of each limiting plate. The cylindrical rod passes through the base and connects to the limiting ring.

[0009] Preferably, the locking assembly includes a fastening screw, which is connected to the base, and the inner side of the fastening screw cooperates with the limiting ring.

[0010] Preferably, the rear connecting block has a support plate inside, the support plate is fixedly connected to the connecting block, and the support plate is rotatably connected to the transmission block.

[0011] Preferably, the front end of the transmission block is provided with a threaded rod, and the front end of the threaded rod is connected to the limiting plate on the rear side.

[0012] Preferably, each of the limiting plates is provided with a movable rod at its bottom, and the inner side of the movable rod is provided with a rack.

[0013] Preferably, the inner side of the rack is engaged with a gear, and the gear is rotatably connected to the base.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The base has built-in expansion screws, which can be firmly installed on concrete walls. With the detachable limit ring on the top that slides to the base, and the locking component connected to the base by fastening screws, the limit ring can be firmly fixed on the base, thereby effectively limiting the position of the conduit in the semi-circular groove, preventing the conduit from shaking or shifting, and ensuring the stability and reliability of the conduit installation.

[0016] 2. The base is circular and magnetic. It can be directly attached to magnetic walls such as metal walls for quick and easy installation. On non-magnetic walls such as concrete walls, it is fixed with built-in expansion screws. One fastener is suitable for various wall types, which greatly expands its application range and improves its flexibility and versatility.

[0017] 3. Through the linkage of components such as transmission block, threaded rod, limiting plate, moving rod, rack and gear, the limiting ring can be fixed from the side, avoiding the problem of inconvenient operation from the top, making the installation process easier and more efficient, and ensuring that the conduit can be fixed smoothly even in special positions.

Detailed Implementation

[0025] The following is in conjunction with the appendix Figures 1-6 The specific embodiments of this utility model will be described in further detail.

[0026] Example 1:

[0027] This utility model includes a base 102, with expansion screws 103 inside the base 102. A detachable limiting ring 101 is provided on the top of the base 102, and the limiting ring 101 is slidably connected to the base 102. A cylindrical hole is provided at the bottom of the limiting ring 101, and a locking assembly is provided on the outer side of the bottom of the limiting ring 101. The locking assembly includes a fastening screw 104, which is connected to the base 102. The inner side of the fastening screw 104 cooperates with the limiting ring 101. The base 102 is generally circular, and the expansion screws 103 for fixing to a concrete wall are provided inside. A semi-circular groove is provided in the middle of the base 102 for placing conduits. Circular holes are reserved on both sides of the semi-circular groove, and screw holes are reserved on both sides of the base 102 to realize the connection and fixation with the limiting ring 101 and other related components.

[0028] The top of the base 102 is provided with a detachable limiting ring 101, which is used to further limit the position of the conduit within the semi-circular groove of the base 102 to prevent the conduit from shaking or shifting. The bottom outer side of the limiting ring 101 is provided with a locking assembly, which includes a fastening screw 104. The fastening screw 104 is connected to the base 102, and the inner side of the fastening screw 104 cooperates with the limiting ring 101. By tightening the fastening screw 104, the limiting ring 101 can be firmly fixed to the base 102, thereby achieving effective fixation of the conduit.

[0029] When applied to a concrete wall, the base 102 is fixed to the concrete wall by the expansion screws 103 inside the base 102. Then, the conduit is placed in the semi-circular groove of the base 102, the upper limit ring 101 is installed, and the upper limit ring 101 is locked by the fastening screws 104 of the locking assembly. The fastening screws 104 fix the upper limit ring 101 through the screw holes reserved on both sides of the base 102, thus completing the installation and fixing of the conduit on the concrete wall.

[0030] Example 2:

[0031] When applied to a metal wall, the base 102 is circular and magnetic. A semi-circular groove is provided in the middle of the base 102 for placing the conduit. Circular holes are reserved on both sides of the semi-circular groove. Screw holes are reserved on both sides of the base 102 to achieve connection and fixation with related components such as the limit ring 101.

[0032] When applied to magnetic walls such as metal or iron, the base 102 can be directly attached to the metal wall surface using its magnetism. The conduit is then placed in the semi-circular groove of the base 102, the upper limit ring 101 is installed, and the upper limit ring 101 is locked using the fastening screw 104 of the locking assembly, thus completing the installation and fixation of the conduit on the magnetic wall. When applied to non-magnetic walls such as concrete walls, the base 102 is fixed to the concrete wall using the expansion screw 103 inside the base 102. The subsequent installation steps are the same as those for magnetic walls.

[0033] Example 3:

[0034] When applied to the top of a wall, where operation on the top area of ​​the base 102 is inconvenient, the locking assembly includes two connecting blocks 201. The two connecting blocks 201 are arranged symmetrically about the center line of the base 102. Each connecting block 201 is hollow, and its inner side is connected to the base 102. A limiting plate 204 is provided inside each connecting block 201, and the limiting plate 204 is slidably connected to the inside of the connecting block 201. A cylindrical rod 205 is provided on the inner side of each limiting plate 204, and the cylindrical rod 205 passes through the base 102 and the limiting ring 1. The cylindrical rod 205 is interconnected, passing through the base 102 and engaging with the bottom circular hole of the limiting ring 101, thus fixing the limiting rod inside the base 102. A support plate 203 is provided inside the rear connecting block 201, fixedly connected to the connecting block 201 and rotatably connected to the transmission block 202. The support plate 203 provides support for the rotation of the transmission block 202, ensuring smooth rotation. Furthermore, the rear side of the transmission block 202 is provided with a cross-shaped groove or an internal hexagonal groove for ease of use. The instrument rotates via a transmission block 202. The front end of the transmission block 202 is provided with a threaded rod 209, which is connected to a rear limiting plate 204. The transmission block 202 drives the threaded rod 209 to rotate, which in turn moves the limiting plate 204 inwards or outwards. Each limiting plate 204 has a moving rod 206 at its bottom. When the rear limiting plate 204 moves inwards, it drives the moving rod 206 inwards. Each moving rod 206 has a rack 207 on its inner side. Gear 208 meshes with the inner side of the base 102. Gear 208 is rotatably connected to the base 102. The movement of the rear side drives the corresponding rack 207 to move. The rack 207 drives the inner gear 208 to rotate. Gear 208 drives the left rack 207 to move inward, thereby driving the front moving rod 206 to move inward. This allows the two cylindrical rods 205 to move inward simultaneously. The two cylindrical rods 205 pass through the base 102 and the bottom of the limiting rod, fixing the limiting rod inside the base 102. In this state, it can be easily installed on the top of the wall.

[0035] When the low-voltage wiring conduit installation fixture is applied to the top of the wall and it is inconvenient to operate on the top area of ​​the base 102, the working process of its locking component is as follows: When the locking component is not operated, the limiting ring 101 is in a movable state and is not firmly fixed to the base 102. At this time, the limiting plates 204 in the two connecting blocks 201 are in a relatively outer position, and the cylindrical rod 205 does not penetrate the base 102 and connect with the bottom circular hole of the limiting ring 101. The limiting ring 101 cannot effectively restrict the position of the conduit in the semi-circular groove of the base 102. Using an instrument (such as a Phillips screwdriver or an Allen wrench) that matches the cross groove or hexagonal groove on the rear side of the transmission block 202, insert it into the groove, and then rotate the instrument to drive the transmission block 202 to rotate smoothly on the support plate 203. Since the support plate 203 is fixedly connected to the connecting block 201, it provides stable support for the rotation of the transmission block 202, ensuring that the transmission block 202 will not shake or jam during rotation. When the transmission block 202 rotates, it drives the threaded rod 209 at its front end to rotate as well. The threaded rod 209 is connected to the rear limiting plate 204. Under the rotation of the threaded rod 209, the rear limiting plate 204 moves inward along the interior of the connecting block 201. Each limiting plate 204 has a moving rod 206 at its bottom. When the rear limiting plate 204 moves inward, it drives the rear moving rod 206 to move inward synchronously. The inner side of the moving rod 206 has a rack 207. The rear moving rod 206 drives the corresponding rack 207 to move inward. The inner sides of the two racks 207 mesh with a gear 208 that is rotatably connected to the base 102. When the rear rack 207 moves inward, it drives the gear 208 to rotate. During the rotation of the gear 208, it drives the left (front) rack 207 to move inward. The inward movement of the front rack 207 causes the front moving rod 206 to move inward, which in turn causes the front limiting plate 204 to move inward. Since the two connecting blocks 201 are arranged symmetrically about the center line of the base 102, and both limiting plates 204 have cylindrical rods 205 on their inner sides, the two cylindrical rods 205 also move inward simultaneously as the two limiting plates 204 move inward. After passing through the base 102, the two cylindrical rods 205 mate with the circular holes at the bottom of the limiting ring 101, thus fixing the limiting ring 101 inside the base 102. At this time, the limiting ring 101 can effectively limit the position of the conduit within the semi-circular groove of the base 102, preventing the conduit from shaking or shifting, thus completing the conduit fixing work when it is inconvenient to operate on the top of the wall.
