DEVICE FOR ADJUSTING HEIGHT OF SUSPENDED LAMP
Document Type and Number:
WIPO Patent Application WO/2019/041626
Kind Code:
A1
Abstract:
A device for adjusting the height of a suspended lamp comprises a guiding combination wheel (1), an operating cord (2), a direction-limiting member (3), and an adjustment housing (4). The adjustment housing (4) is connected to a lamp. The guiding combination wheel (1) and the direction-limiting member (3) are provided in the adjustment housing (4). A circumferential end surface of the guiding combination wheel (1) is recessed inwards in a radial direction to form a wheel slot (5). The operating cord (2) is provided in the wheel slot (5). One end of the operating cord (2) extends out of the adjustment housing (4), and is fixed at a higher end of a moving region of the lamp. The other end of the operating cord (2) extends out of the adjustment housing (4) and acts as a free end. The direction-limiting member (3) acts on the guiding combination wheel (1), and limits a rotation direction of the guiding combination wheel (1). One end of the operating cord (2) is fixed at the higher end of the moving region of the lamp. Pulling on the free end of the operating cord (2) moves the lamp towards a higher position of the operating cord (2). As plants grow, the invention is capable of easily adjusting the height of the lamp at any time, thereby consuming less power, reducing waste, and providing an improved supplementary light source for plants.
