As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, a first embodiment of the present invention provides a chair 100 for eyesight test, which includes a chair body 2, a base 3, a lifting mechanism 4, a lifting control switch 5, a measuring rod 6 and a pillow support mechanism 7. The lifting mechanism 4 and the measuring rod 6 are arranged on the base 3 at intervals, and the measuring rod 6 is provided with scales 62 along the vertical direction; the chair body 2 is connected with the end part of the lifting mechanism 4 far away from the base 3 and is movably sleeved on the measuring rod 6; the lifting control switch 5 is arranged on the chair body 2 and connected with the lifting mechanism 4, and the lifting control switch 5 controls the lifting mechanism 4 to drive the chair body 2 to do lifting motion along the measuring rod 6; the pillow support mechanism 7 includes a pillow support 72 and a telescopic member 74. The pillow support 72 is sleeved on the measuring rod 6 and is located on one side of the chair body 2 far away from the base 3. The pillow support 72 is provided with a reference mark 721, and the reference mark 721 is positioned on the same horizontal line with the eyes of the person who tests the eyesight. The reference mark 721 may be a reference plane or a reference line. In the present embodiment, the reference mark 721 is a top surface of the pillow 72. The extensible member 74 is connected to the pillow 72 and the chair body 2, and the extensible member 74 can drive the pillow 72 to move along the measuring rod 6 when being stressed, so as to measure the distance between the reference mark 721 and the ground through the measuring rod 6.
In the present embodiment, the lifting control switch 5 includes a lifting control switch 52 and a lowering control switch 54, and both the lifting control switch 52 and the lowering control switch 54 are connected to the lifting mechanism 4, wherein the lifting control switch 52 is used for controlling the lifting mechanism 4 to lift vertically, and the lowering control switch 54 is used for controlling the lifting mechanism 4 to lower vertically.
In the present embodiment, the chair body 2 includes a seat 22 and a backrest 24 connected to one side of the seat 22. The seat 22 is connected to the lifting mechanism 4, the backrest 24 is movably sleeved on the measuring rod 6, and armrests 26 are disposed on two opposite sides of the seat 22. The up control switch 52 and the down control switch 54 are installed on the armrest 26 at intervals.
In this embodiment, the pillow support 72 is movably sleeved on the measuring rod 6, and the pillow support 72 is provided with a head positioning groove 723 for a person with eyesight to rest on. In this embodiment, the head positioning groove 723 is substantially an arc-shaped groove matching the shape of the human back of the brain.
In this embodiment, the telescopic member 74 includes a sleeve 742, a stretching rod 744 and a locking screw 746. One end of the sleeve 742 is connected to a side of the seat back 24 away from the base 2, the stretching rod 744 is movably inserted into the sleeve 742, the locking screw 746 is screwed to the sleeve 742, and one end of the locking screw abuts against the stretching rod 744 to fix the stretching rod 744 to the sleeve 742; the stretch rod 744 is able to slide along the sleeve 742 under force when the lock screw 746 is loosened. The pillow support 72 is mounted on the stretching rod 744.
In the present embodiment, the lifting mechanism 4 is a motor, and includes a motor body 42 and a motor shaft 44 movably connected to one end of the motor body 42. The motor body 42 is installed in the base 3, and the free end of the motor shaft 44 is connected to the seat 22.
The chair 100 for optometry is used by measuring in advance the height between each row of optotypes and the ground on a standard visual chart (not shown). The vision test person sits on the vision test chair 100, and the height of the pillow support 72 is adjusted through the telescopic piece 74, so that the back head of the vision test person is placed in the head positioning groove 723 of the pillow support 72, and the vision test person is prevented from moving forward in the test process. The measuring rod 6 is observed to find the height between the reference mark 721 of the pillow 72 and the ground. If the visual target labeled 1.0 is detected (the height between the visual target labeled 1.0 and the ground is H0), if H0 is higher than the reference mark 721 of the pillow 72, the lift mechanism 4 is controlled by the lift control switch 52 to drive the chair body 2 and the pillow 72 connected to the chair body 2 to be lifted simultaneously until the height between the reference mark 721 of the pillow 72 and the ground is equal to H0. If H0 is lower than the reference mark 721 of the pillow 72, the elevating mechanism 4 is controlled by the lowering control switch 54, and the chair body 2 and the pillow 72 connected to the chair body 2 are driven to be lowered at the same time until the height between the reference mark 721 of the pillow 72 and the ground is equal to H0. Since the fiducial mark 721 of the pillow 72 is located on the same horizontal plane as the eyes of the vision tester, when the height between the fiducial mark 721 of the pillow 72 and the ground is equal to H0, the fiducial mark 721 of the pillow 72, the eyes of the vision tester, and the optotype marked as 1.0 are all located on the same horizontal plane. Through the lifting chair body 2 and the pillow support 72, the eyes of the vision detector and different detected visual targets are kept on the same horizontal plane, and the accuracy of vision detection is improved.
Referring to fig. 2, a second embodiment of the present invention provides a chair 200 for eyesight test, which has a structure substantially the same as the chair 100 for eyesight test in the first embodiment, and includes a chair body 8, a base 9, a lifting mechanism 11, a lifting control switch 13, a measuring rod 14, and a pillow mechanism 15. The lifting mechanism 11 and the measuring rod 14 are arranged on the base 9 at intervals; the measuring rod 14 is provided with scales 142 along the vertical direction; the chair body 8 is connected with the end part of the lifting mechanism 11 far away from the base 9 and is movably sleeved on the measuring rod 14; the lifting control switch 13 is installed on the chair body 8 and connected with the lifting mechanism 11, and the lifting control switch 13 controls the lifting mechanism 11 to drive the chair body 8 to move up and down along the measuring rod 14.
The visual acuity test seat 200 differs from the visual acuity test seat 100 according to the first embodiment in that: in the present embodiment, the pillow mechanism 15 includes a driving mechanism 152, a driving switch 154, and a pillow 156. The driving mechanism 152 is mounted on the chair body 8 and connected to the pillow 156. The driving switch 154 is mounted on the pillow 156 and connected to the driving mechanism 152.
