Detailed Description
The following describes in detail the examples of the present utility model, which are implemented on the premise of the technical solution of the present utility model, and detailed embodiments and specific operation procedures are given, but the scope of protection of the present utility model is not limited to the following examples.
Example 1
As shown in fig. 1 to 5, a foldable light feeding instrument of the present embodiment includes a base 1, a lens 2, and a rotational connection base 3; the lens 2 is located above the base 1 and is connected with the base 1 through the rotary connecting seat 3, so that the lens 2 and the rotary connecting seat 3 can be folded and unfolded relative to the base 1 to have a folded state and an unfolded state. When the device is in a folded state, the occupied space is small, and the device is convenient to store and transport; when the device is in the unfolding state, the normal use requirement of the light feeding instrument can be met.
Further, in the present embodiment, two mounting ends, namely a first mounting end 31 and a second mounting end 32, are disposed on the rotary connecting seat 3; the rotary connecting seat 3 is rotationally connected with the lens 2 through the first mounting end 31 matched with the first rotary piece 33 and simultaneously rotationally connected with the base 1 through the second mounting end 32 matched with the second rotary piece 34, so that the lens 2 and the rotary connecting seat 3 can relatively rotate, and meanwhile, the rotary connecting seat 3 and the base 1 can relatively rotate.
Further, in the present embodiment, the upper surface of the base 1 is provided with a receiving groove 11, and the structural shape of the receiving groove 11 corresponds to the structural shape of the rotating connection base 3. When the lens 2 and the rotary connecting seat 3 are in the folded state, the rotary connecting seat 3 is received in the receiving groove 11, and at the same time, the lens 2 is in the abutting state parallel to the rotary connecting seat 3. When the lens 2 and the rotary connecting seat 3 are in the unfolded state, the rotary connecting seat 3 withdraws from the accommodating groove 11 and forms a certain unfolding angle with the base 1 (freely adjusted according to the requirement), and meanwhile, the lens 2 is unfolded at a certain angle relative to the rotary connecting seat 3 (freely adjusted according to the requirement).
In addition, in the present embodiment, the lens 2 includes a hood 21 and two lens barrels (not shown) provided in the hood 21, the front ends of which are provided with observation members 22; the periphery of the observation part 22 is provided with a silica gel sleeve 221, two observation holes 222 are formed in the observation part 22 at positions corresponding to eyes of people, and lenses 223 are mounted on the observation holes 222. The lens 2 further comprises a knob 23; the knob 23 is located in a knob hole on the cover 21 for adjusting the interval between the two lens barrels.
Meanwhile, in this embodiment, a silica gel pad 12 is provided at the bottom of the base 1, and a display 13 and a switch button 14 are provided at the upper part of the base 1. The display 13 is used for displaying and adjusting parameters of the device, and the switch key 14 is used for opening and closing the whole device.
The using method comprises the following steps:
when the folding placement is needed, the rotary connecting seat 3 is rotated relative to the base 1 through the second rotating piece 34 until the rotary connecting seat 3 completely enters the accommodating groove 11 of the base 11; then, the lens 2 is rotated relative to the rotating connecting seat 3 by the first rotating member 33 until the lens 2 is completely abutted against the surface of the rotating connecting seat 3. When the device needs to be unfolded and used, the rotary connecting seat 3 rotates relative to the base 1 through the second rotating piece 34 until the rotary connecting seat leaves the accommodating groove 11; then, the lens 2 is rotated relative to the rotational coupling base 3 by the first rotation member 33 until the target desired angular position is reached.
