[0023] In the application, a kind of portable house for vision testing is provided, mainly for placing vision testing instrument inside when detecting outdoors, to facilitate personnel to carry out vision detection, telescopic frame 3 and top frame 4 in the house are mainly prepared from relatively thin metal material, mainly for the role of sunshade and rainproof, when using the house, vision testing instrument is placed inside, then personnel enters and closes door 5 to carry out vision test, and when the house needs to be transferred, drive assembly 6 needs to be operated to drive connecting assembly 7 to slightly lift top frame 4, so that door 5 can be detached from between top frame 4 and chassis 2, after door 5 is detached, drive assembly 6 is operated to drive connecting assembly 7 to move top frame 4 downwards, so that telescopic frame 3 is all located inside chassis 2, at this time, the bottom end of top frame 4 is attached to the top end of chassis 2, so that the overall height of the house is reduced, which can place the house on a truck when transferring, to solve the problem that vision testing room in the prior art cannot be placed in the truck due to height when transferring, causing inconvenience in transferring.

[0024] Preferably, the bottom end of the support bottom end is provided with four sliding wheels 11 in pairs of symmetry.

[0025] The sliding wheels 11 can facilitate short-distance movement of the vision testing room, so that it can be conveniently moved on the ground to the position to be moved after unloading.

[0026] Preferably, the driving assembly 6 comprises a first placing rack 61, a driving gear 63, a rotating rod 62, a sliding connecting rack 64, a rocker 65, a fixed block 66 and a second placing rack 67. The first placing rack 61 is arranged on the side wall of the chassis 2. One end of the rotating rod 62 is rotatably arranged on one side of the first placing rack 61. The driving gear 63 is arranged on the rotating rod 62. The driving gear 63 is connected with the connecting assembly 7. The driving of the driving gear 63 can move the connecting assembly 7. The sliding connecting rack 64 is slidably arranged in the other end of the rotating rod 62. One end of the rocker 65 is connected with the sliding connecting rack 64. The fixed block 66 is arranged on the other end of the rocker 65. The second placing rack 67 is arranged on the side wall of the first placing rack 61. The rocker 65 is located on one side of the second placing rack 67. A fixed groove 671 is arranged in the other side of the second placing rack 67. The fixed block 66 corresponds to the fixed groove 671.

[0027] In the present application, the driving assembly 6 is mainly used to drive the connecting assembly 7 to move, so that the connecting assembly 7 can drive the top frame 4 to move vertically. The rocker 65 arranged in the driving assembly 6 can be operated by the operator. The operator can rotate the rocker 65 to drive the rotating rod 62 to rotate in the first placing rack 61 through the sliding connection of the sliding connecting rack 64 and the rotating rod 62. The rotating rod 62 can drive the driving gear 63 to rotate when rotating, so that the connecting assembly 7 can move. Since the sliding connecting rod and the rotating rod 62 are connected by sliding, the rocker 65 can move. When the rocker 65 moves towards the inside of the second placing rack 67, the fixed block 66 connected to the other end of the rocker 65 can move into the fixed groove 671. In this way, the fixed block 66 can limit the movement of the rocker 65, thereby fixing the rotating rod 62 and the driving gear 63. When the rocker 65 moves towards the outside of the second placing rack 67, the fixed block 66 will fall out of the fixed groove 671. In this way, the rocker 65 can drive the rotating rod 62 to rotate through the sliding connecting rod.

[0028] Preferably, the connecting assembly 7 comprises a fixed column 71 and a connecting rack 72. The fixed column 71 is fixedly arranged on the side wall of the top frame 4. The top end of the connecting rack 72 is arranged on the bottom end of the fixed column 71. The bottom end of the connecting rack 72 passes through the first placing rack 61 and is located below the first placing rack 61. The part of the connecting rack 72 located inside the first placing rack 61 is engaged with the driving gear 63.

[0029] In the application, the connecting rack 72 can move up and down when the driving gear 63 rotates, and the placing frame 61 can play a certain limiting role. The connecting rack 72 can drive the top frame 4 to move synchronously through the fixed column 71 when moving up and down, so that the top frame 4 and the telescopic frame 3 can move vertically on the bottom frame 2.

[0030] Preferably, the two sides of the fixed column 71 are symmetrically provided with two connecting fixed frames 711, and one limiting rod 712 is arranged at the bottom end of each connecting fixed frame 711. The two limiting rods 712 are respectively located on the two sides of the top frame 4, and two limiting columns 713 are symmetrically arranged on the two sides of the bottom frame 2. Each limiting column 713 is located below one limiting rod 712, and each limiting rod 712 is slidingly located in one limiting column 713.

[0031] In the application, the connection of the two connecting fixed frames 711 through the two limiting rods 712 and the limiting columns 713 can make the vertical movement of the top frame 4 more stable, and the problem of easy shaking or deviation of one-sided movement can be avoided.

[0032] The above is only an embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the scope of the claims of the present application.
