[0030] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model is described clearly and completely below. Obviously, the described embodiments are part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary persons in the field without creative work are within the scope of protection of the utility model.

[0032] At present, during the inspection process, the hospital needs to prepare a large number of shields for the inspectors to use, and in order to separate the shields to be used from the used shields, two additional large areas need to be divided for independent storage of the shields. If outdoor inspection is required, there will be a problem of using a large number of tools and the tools are placed in a complicated manner, resulting in low inspection efficiency for medical staff. In view of the above problems, the utility model provides a seat suitable for vision inspection, wherein the shield is connected to the seat through an adjustable structure, and the shield can be switched between inspection use and storage status according to actual needs. When the inspector conducts the inspection, the disposable sheath is put on the shield, and the position of the shield is adjusted to conduct the vision inspection.
[0033] Reference Figure 1 as well as Figure 2 As shown, the utility model relates to a chair 1 suitable for visual inspection, which also includes a shield 2. A connecting assembly is provided on the back of the chair 1, and the shield 2 is connected to the chair 1 through the connecting assembly. The connecting assembly includes a vertical rod 3, a cantilever rod 4 and a hand grip 5, wherein the vertical rod 3 is provided on the back of the chair 1. The cantilever rod 4 is hinged to the end of the vertical rod 3, and the cantilever rod 4 rotates from a vertical state to a horizontal state to cross the shoulders of the examiner and hang outside in front of the examiner. One end of the hand grip 5 is hinged to the cantilever rod 4, and the other end is connected to the shield 2; when the cantilever rod 4 is flipped to a horizontal state, the rotation axis of the hand grip 5 is vertically arranged.
[0034] It should be noted that, in this embodiment, the cantilever rod 4 is mainly used to assist the hand grip rod 5 to cross the examiner's shoulders, so that the hand grip rod 5 can pass over the examiner and move in front of the examiner.
[0035] For example, when using the chair 1 to conduct a vision test on the examinee, the examinee is guided to sit down, and to pick up the hand grip 5 and move the hand grip 5 in front of the eyes. During the movement of the hand grip 5, the cantilever rod 4 will be driven to flip, so that the hand grip 5 can cross from the back of the chair 1 to the front of the examinee. During the subsequent examination, the eyes can be covered with the shield 2 according to the guidance of the medical staff. Through the setting of this structure, the medical staff no longer needs to organize a large number of shields 2 in the early stage of the examination, thereby improving the work efficiency of the medical staff. In terms of hygiene, the medical staff only needs to prepare disposable covers, and the examiner can put on the prepared disposable covers during the examination.
[0036] In one embodiment, it is more preferable that storage boxes are provided on both sides of the seat 1, one of which is used to place disposable protective covers, and the other is used to place the examiner's glasses, so that the examiner can put the glasses in the storage box at will during the examination. Generally, when checking the vision of a person wearing glasses, it is necessary to measure the naked eye vision first. At this time, it is necessary to take off the glasses and put them aside. After measuring the naked eye vision, put on the glasses again to check the corrected vision.
[0037] In order to facilitate replacement of the shielding plate 2 , in this embodiment, the shielding plate 2 is threadedly connected to the handle bar 5 .
[0038] In one embodiment, in order to facilitate the examiner to take, two plates and two connecting components are provided respectively, and are arranged on both sides of the seat 1.
[0039] Reference Figure 3 As shown, in one embodiment, a limiting member 6 is provided on the vertical rod 3. When the cantilever rod 4 is flipped to a horizontal state, the cantilever rod 4 contacts the limiting member 6, and the limiting member 6 supports the cantilever rod 4 under force.
[0040] The setting of the limiter 6 limits the rotation of the cantilever rod 4. When the cantilever rod 4 is flipped to a horizontal state, the cantilever rod 4 contacts the limiter 6. At this time, the limiter 6 limits the cantilever rod 4 from continuing to rotate downward, and the limiter 6 supports the cantilever rod 4 with force. During the inspection, when the cantilever rod 4 is flipped to a horizontal state, the handle bar 5 moves in front of the inspector. The setting of this structure can achieve a higher pre-positioning effect. At this time, the inspector only needs to adjust the handle bar 5, which is convenient for the inspector to perform the shielding operation.
[0041] In one embodiment, it is more preferable that a storage tube 7 is provided on the back of the seat 1, and a sliding seat is provided at the bottom of the vertical rod 3. The sliding seat passes through the storage tube 7 and is vertically slidably connected with the storage tube 7. At the same time, a limiting structure is provided on the top of the storage tube 7 to position the sliding seat.
[0042] It should be noted that the storage tube 7 is configured to store the vertical rod 3 and the cantilever rod 4. When no inspection is required, the vertical rod 3 and the cantilever rod 4 can be stored, and the product can be used as an ordinary chair 1. When storing, the cantilever rod 4 needs to be flipped to a vertical state, and then the vertical rod 3 and the cantilever rod 4 are gradually inserted into the storage tube 7 to achieve overall storage.
[0043] Among them, the setting of the limiting structure plays a positioning role for the slide and the vertical rod 3. When the chair 1 needs to be inspected, the limiting structure can position the slide in the upper half of the storage tube 7 so that the inspector can move the handle 5 to adjust the baffle 2.
[0044] In one embodiment, specifically, the storage tube 7 includes a positioning section and a movable section, wherein the positioning section is arranged with an interference fit with the sliding seat, and the movable section is arranged with a clearance fit with the sliding seat.
[0045] The interference fit setting creates a damping effect between the slide and the positioning section. When moving the slide in the positioning section, the vertical rod 3 needs to be pulled out while overcoming the damping, wherein the damping can position the height of the slide, thereby achieving height positioning of the vertical rod 3.
[0046] Reference Figure 3 As shown, in one embodiment, specifically, the limiting structure includes limiting holes 8, and the limiting holes 8 are arranged at intervals on the storage tube 7. The slide seat is horizontally slidably connected to the limiting convex shaft 9, and the limiting convex shaft 9 is also provided with an elastic member, which pushes the limiting convex shaft 9 into the limiting hole 8. Among them, the elastic member includes a spring, one end of the spring is connected to the slide seat, and the other end is connected to the limiting convex shaft 9.
[0047] The setting of multiple limit holes 8 allows the height of the vertical rod 3 to have multiple height adjustment gears. When the height of the inspector is different and the height of the baffle 2 needs to be adjusted, the vertical rod 3 is pulled upward and the limit cam 9 is pressed to make the limit cam 9 disengage from the limit hole 8, and then the vertical rod 3 is pulled out. After the vertical rod 3 reaches the adaptation position, the vertical rod 3 continues to be moved so that the limit cam 9 is inserted into the adjacent limit hole 8 under the action of the elastic member, thereby achieving the height positioning of the slide seat. The effect of facilitating height adjustment can also improve the operational flexibility of the overall structure.
[0048] In one embodiment, a boss 10 is provided at one end of the handle bar 5, and the diameter of the boss 10 is larger than the diameter of the storage tube 7. The boss 10 is provided to store and position the handle bar 5. When the cantilever bar 4 is inserted into the storage tube 7 for storage, the boss 10 of the handle bar 5 will be stuck in the tube mouth of the storage tube 7, thereby realizing the storage and positioning of the handle bar 5.
[0049] When using the chair 1 to perform a vision test on the examinee, first place the disposable protective cover needed in one of the storage boxes, then instruct the examinee to sit down, and instruct the examinee to pick up the hand grip 5 and move the hand grip 5 to the front of the eyes. During the movement of the hand grip 5, the cantilever rod 4 will be driven to flip, so that the hand grip 5 can cross from the back of the chair 1 to the front of the examinee, and finally put on the disposable protective cover. During the subsequent examination, the shield 2 can be used to cover the eyes according to the guidance of the medical staff. During the test, if the examinee needs to take off the glasses he is wearing, he can put the glasses in another storage box.
[0050] During the inspection, when the height of the shield 2 needs to be adjusted due to the height of the inspector, the vertical rod 3 is pulled upward, and the limiting convex shaft 9 is pressed to make the limiting convex shaft 9 disengage from the limiting hole 8, and then the vertical rod 3 is pulled out. After the vertical rod 3 reaches the fitting position, the vertical rod 3 is continued to be moved, so that the limiting convex shaft 9 is inserted into the adjacent limiting hole 8 under the action of the elastic member, and the height adjustment of the vertical rod 3 is completed;
[0051] When the inspection is not needed, the vertical rod 3 and the cantilever rod 4 can be stored, and the product can be used as an ordinary chair 1. When storing, the cantilever rod 4 needs to be flipped to a vertical state, and then the vertical rod 3 and the cantilever rod 4 are gradually inserted into the storage tube 7. When the cantilever rod 4 is inserted into the storage tube 7 for storage, the boss 10 of the hand grip rod 5 will be stuck in the tube mouth of the storage tube 7, so as to achieve the storage of the hand grip rod 5 and the whole.
