Description

Technical Field

[0001] This utility model relates to the field of conduit protection technology, specifically a protective device for conduits in low-voltage engineering. Background Technology

[0002] Conduit, also known as electrical conduit, is a piping system used for the laying and protection of electrical wires and cables. It is widely used in electrical engineering to organize, protect, and guide wires and cables, while providing physical support and isolation to ensure the safe and reliable operation of electrical systems.

[0003] Upon investigation, a Chinese utility model patent discloses a protective device for low-voltage electrical conduit (publication number: CN222321007U), which includes an upper protective ring, an inner ring, and a lower protective ring. Threaded rods are fixedly connected to both sides of the lower protective ring, and positioning rings are movably installed around the threaded rods. Fixing blocks are fixedly connected to one side of the lower protective ring at both ends of the threaded rods, and locking blocks are fixedly connected to the other side of the lower protective ring at both ends of the threaded rods.

[0004] Although the aforementioned patent allows for the quick installation of multiple lower protective rings by connecting multiple devices together and having adjacent devices snap into the interior of a fixing block, without the need for tools to install the devices sequentially, the cable size is smaller than the protective ring. The cable will wobble inside the protective ring. Furthermore, the protective rings of this device are directly limited by the elastic elements on the snap blocks. When the cable wobbles inside the protective ring, it will strike the protective ring. Under the action of external force, the elastic elements on the snap blocks will deform, releasing the limit and affecting the fixing effect of the protective ring.

[0005] Therefore, this utility model provides a protective device for low-voltage electrical conduit to solve the above problems. Utility Model Content

The limiting mechanism includes a locking block and a second spring. The locking block is slidably connected within the cavity, and a slot is formed on one side of each insert block, with the locking block inserted into the slot.

[0010] As a preferred technical solution of this application, a connecting plate is fixedly connected inside the cavity, and the limiting mechanism further includes a round rod, one end of which is fixedly connected to the locking block, and the other end of which slides through the connecting plate. The second spring is sleeved on the round rod, and both ends of the second spring are fixedly connected to the locking block and the connecting plate, respectively.

[0012] As a preferred technical solution of this application, the first spring is sleeved on the telescopic rod, and the two ends of the telescopic rod and the first spring are fixedly connected between the lower positioning ring and the lower protective ring, and between the upper positioning ring and the upper protective ring.

[0013] As a preferred technical solution of this application, a fixing block is symmetrically fixed on both the lower positioning ring and the upper positioning ring, and a support piece is provided between the lower positioning ring and the upper positioning ring, with both ends of the support piece inserted into the fixing block.

[0014] As a preferred technical solution of this application, the fixing block is threaded with a fixing bolt, and the end of the fixing bolt abuts against the support plate.

[0015] (III) Beneficial Effects
