Embodiment Construction

[0019] The height adjustment device and the lighting fixture using the height adjustment device will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Please also refer to figure 1 and figure 2 , a lighting fixture 100 of an embodiment includes a height adjustment device 10 and two lighting fixtures 30 . The height adjusting device 10 includes an inner rod 11 and an outer rod 13 sleeved on the inner rod 11 . The inner rod 11 and the outer rod 13 are made of aluminum alloy material. The inner rod 11 is roughly a cylindrical rod, and a beam 12 perpendicular to the inner rod 11 is arranged on the top thereof. Two lamps 30 are respectively hung on two ends of the beam 12 . Each lamp 30 leads a power cord 31 and an aviation plug 33 located at the end of the power cord 31 . A plurality of first positioning holes 111 are evenly spaced in sequence on the inner rod 11 .

[0021] The outer rod 13 is generally a hollow cyl...

Abstract

The invention relates to a height adjusting device and a lighting lamp using the same. The height adjusting device comprises an inner rod, an outer rod sleeved on the inner rod, and a protection ring arranged at the joint part between the inner rod and the outer rod and sleeved on the inner rod, wherein the inner rod is provided with a plurality of first positioning holes, and the protection ring is provided with a plurality of second positioning holes corresponding to the plurality of first positioning holes. The height adjusting device also comprises first positioning pins which are arranged in the first positioning holes and the second positioning holes in a penetrating way. When a user holds the inner rod to slide towards the outer rod, and the hand can be in contact with the protection ring first, therefore the hand can be prevented from being injuring by the outer rod.

Description

【Technical field】 [0001] The invention relates to a height adjusting device and a lighting fixture using the height adjusting device. 【Background technique】 [0002] In large and medium-sized lighting systems, it is often necessary to adjust the height of the lamps and lanterns to meet different lighting needs. [0003] Traditional lighting fixtures generally use multi-section lifting rods to achieve height adjustment functions. However, due to differences in the diameters of multi-section rods, when using manual methods to operate multi-section rods, joints between two adjacent lifting rods often occur The problem of pinched hands. 【Content of invention】 [0004] Based on this, it is necessary to provide a height adjustment device that avoids pinching hands when adjusting the height and a lighting fixture using the height adjustment device. [0005] A height adjustment device includes an inner rod, an outer rod sheathed on the inner rod, and a protective ring arranged a...
