Description
Technical Field
[0001] The utility model relates to the technical field of weak current system wiring, in particular to a weak current system installation wiring device. Background Art
[0002] Weak current system refers to the system used to transmit low voltage and low current signals and data in buildings. It includes but is not limited to communication systems, security monitoring systems, building automation systems, TV monitoring systems, etc. Weak current system plays an important role in modern buildings, providing support for the safety, convenience and intelligence of buildings.
[0003] When the weak current system is installed, a wiring box is needed to store the equipment and protect it. Since the weak current system is relatively complex and there are many lines, the lines need to be wired. Usually, there will be a bayonet for the lines to be concentrated in the wiring box. By placing the wires in the bayonet, the wiring is centralized.
[0004] The wires can be concentrated by using bayonet, but the bayonet is generally fixed, and the interface positions of the devices are different, resulting in different densities of the wires and different concentration positions. As a result, some bayonet have more wires and some have fewer wires, and the fixing effect is not good. Due to the different heights of the devices, the heights of the wires are different. Placing them directly in the bayonet can easily cause the wires to bend, which accelerates the aging of the wires. Utility Model Content
[0005] 1. Technical issues to be resolved
[0006] The technical problem to be solved by the utility model is that the bayonet is generally fixed, while the interface positions of the devices are different, resulting in different densities of the wires, different concentrated positions, and poor fixing effects. Due to the different heights between the devices, the heights of the wires are different. Directly placing the wires in the bayonet can easily cause the wires to bend, accelerating line aging.
[0007] (II) Technical solution
[0008] The cam is provided with a first end fixedly provided with a first bolt, and the second end of the first bolt is connected with a second bolt by a threaded connection to the first and second guide rails.
[0009] As an improvement, the fixing mechanism includes a rotating shaft on both sides of the connecting block, one end of the rotating shaft is fixedly connected to a threaded column, a nut is threadedly connected to the threaded column, and protrusions correspondingly arranged on both sides are fixedly connected to the nut.
[0010] As an improvement, the moving mechanism includes a threaded hole on the extension rod, a screw rod is threadedly connected to the threaded hole, and one end of the screw rod is rotatably connected to the sliding rod.
[0011] As an improvement, the adjustment mechanism includes a pin movably plugged into the first arc-shaped card plate, one end of the pin is fixedly connected to the second arc-shaped card plate, and a spring sleeved on the pin is fixedly connected between the second arc-shaped card plate and the first arc-shaped card plate.
[0012] As an improvement, the slide rod is provided with limit blocks arranged correspondingly on both sides, and the connection block is provided with limit grooves in the slide groove that cooperate with the limit blocks.
[0013] (III) Beneficial effects
[0014] The advantages of the utility model compared with the prior art are:
[0015] The extension rod is driven to move by the screw rod, and the second arc-shaped clamping plate is adjusted by the spring to fix the wire, which can adapt to wires of different densities. By rotating the connecting block, the second bolt adjusts the length of the extension rod to adapt to the height of the equipment, thereby preventing the wire from bending.
