DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figure 1-Figure 5 The utility model provides a technical solution: a multi-purpose portable ophthalmic examination device, including a protective box 1, a handle 2, a top plate 3, an inspection instrument body 4, a movable plate 5, a limiting sleeve rod 6, a limiting slide rod 7, a threaded seat 8 and a rotating seat 9. The four corners of the protective box 1 are evenly provided with limiting slide rods 7, the front and rear end surfaces of the protective box 1 are symmetrically provided with handles 2, the upper end surface of the protective box 1 is slidably provided with a top plate 3, the lower end surface of the top plate 3 is installed with an inspection instrument body 4, the left and right sides of the top plate 3 are provided with a rotating seat 9, the left and right sides of the top plate 3 are symmetrically provided with movable plates 5, the lower end surface of the movable plate 5 is welded with a limiting sleeve rod 6, and the upper end surface of the movable plate 5 is embedded with a threaded seat 8. This design solves the problem that the original portable ophthalmic examination device is not convenient to deploy and use.

[0021] As the first embodiment of the utility model: a rotating chamber 51 is provided inside the movable plate 5, and a rotating seat 9 is arranged inside the rotating chamber 51. The movable plate 5 can rotate freely through the rotating seat 9 and the rotating chamber 51. The rotating chamber 51 cooperates with the rotating seat 9 to limit the movable plate 5 and make it flippable, so as to adjust the position of the inspection instrument body 4. Locking grooves 91 are provided at the upper and lower ends of the rotating seat 9, and a locking bolt 81 is provided inside the threaded seat 8 for engagement. The rotation of the locking bolt 81 can drive itself to move up and down through the threaded seat 8, and the engagement has a self-locking effect. The lower end of the locking bolt 81 is engaged with the locking groove 91, and the locking bolt 81 and the locking groove 91 can limit the rotation of the rotating seat 9, thereby fixing the angle of the movable plate 5. The limit sleeve 6 moves along the limit slide 7 to change the height of the movable plate 5. A positioning groove 61 is provided at the lower end of the outer side surface of the limit sleeve 6. A positioning claw 63 is welded on the outer side surface of the rotating kit 62. The rotating kit 62 can rotate freely along the inner wall of the positioning groove 61 through the positioning claw 63. This design allows the rotating kit 62 to rotate independently of the limit sleeve 6. A threaded groove 621 is provided inside the rotating kit 62. The threaded groove 621 and the threaded head 71 are meshed with each other. A bottom pad 11 is bonded to the lower end surface of the protective box 1. The threaded groove 621 and the threaded head 71 can limit the rotating kit 62 and the limit slide 7.

[0022] As a second embodiment of the utility model: the user can pull the protective box 1 by the handle 2 to travel. When the user needs to unfold the inspection device body 4 for use after arriving at the destination, the protective box 1 is first placed on the horizontal ground, and then the top plate 3 is pulled upward, and the top plate 3 drives the movable plate 5 to move upward together, and the movable plate 5 drives the limit sleeve rod 6 to move upward along the outer side of the limit slide rod 7 until the limit sleeve rod 6 is lifted to the top. At this time, the upper end of the rotating kit 62 is in contact with the lower end of the threaded head 71. At this time, the rotating kit 62 is held and rotated so that the thread groove 621 It is tightly engaged with the threaded head 71, thereby fixing the position between the limit sleeve 6 and the limit slide rod 7 to support the top plate 3. Then, the locking bolt 81 is loosened, and the top plate 3 is flipped 180° with the connecting line of the two sets of rotating seats 9 as the axis, so that the inspection device body 4 located at the lower end surface of the top plate 3 is flipped to the top. At this time, the locking bolt 81 is tightened again. The locking bolt 81 moves inward under the action of the threaded seat 8 and engages with the locking groove 91, thereby limiting the angle of the rotating seat 9 and the top plate 3. Then, the inspection device body 4 can be operated normally for use.
