Expandable composite material wire duct

Abstract

The invention discloses an expandable composite material wire duct which comprises a width-adjustable wire duct cover and a wire duct body, the wire duct body and the wire duct cover define a long-strip-shaped wire duct cavity used for placing wires, the wire duct cover is formed by splicing a left wire duct cover and a right wire duct cover, and the wire duct body is formed by splicing a left wire duct body and a right wire duct body. Expansion connection structures are arranged between the left wire duct cover and the right wire duct cover and between the left wire duct body and the right wire duct body. Due to the adoption of the expansion connection structure, the wire duct cover and the wire duct body can freely stretch out and draw back according to different numbers of arranged wires, so that the width of the wire duct can be flexibly adjusted, and the universality is high; and meanwhile, the width of the wire duct can be adjusted, so that the requirements of arrangement of various wires with different numbers can be met by using wire ducts with few specifications, the specifications of the wire ducts are greatly reduced, the production and processing are facilitated, and the management cost is reduced.

Description

technical field [0001] The invention relates to the technical field of wire grooves, in particular to an expandable composite material wire groove. Background technique [0002] At present, as a structure for accommodating wires, the wire trough can be neatly planned when wiring the elevator machine room, which is not only conducive to the clear and orderly placement of the wires, but also to the unified management. The width of the wire trough in the prior art is fixed and cannot be widened. When the capacity of the wire trough is not enough, it must be changed to a wire trough of a larger size, or a new wire trough must be added, resulting in a large number of wire trough specifications, high management costs, and flexibility. In addition, in order to prevent electromagnetic waves generated by wires in the wire trough from interfering with other electrical components in the elevator machine room, traditional wire troughs are generally made of metal, which is heavy in weigh...

Problems solved by technology

The width of the wire slot in the prior art is fixed and cannot be widened. When the capacity of the wire slot is not enough, a wire slot of a larger size must be used, or a new wire slot must be added, resulting in many wire slot specifications, high management costs, and flexible In addition, in order to prevent the electromagnetic waves generated by the wires in the trunking from interfering with other electrical components in the elevator machine room, the traditional trunking is generally made of metal, which is heavy and expensive
