Description
Technical Field
[0001] The utility model relates to the technical field of optometry institutions, in particular to a supporting and assisting mechanism for ophthalmic medical optometry. Background Technique
[0002] An optometer is used to check the focusing condition of light after it enters the eyeball. Taking the state of an emmetropic eye as the standard, it measures the degree of convergence and divergence difference between the eye to be examined and the emmetropic eye. This is a medical device, which is mostly used with a corresponding head supporting mechanism and is quite common in the ophthalmic examination area.
[0003] In the process of implementing the present utility model, the inventor found that the following problems in the prior art have not been solved: Although the existing supporting and assisting mechanism for ophthalmic medical optometry has the functions of horizontal and height adjustment, since the doctor and the examinee sit face to face for the examination, during the process of aligning the eyes with the machine, the doctor needs to check the optometer in real time and communicate with the examinee. The examinee rotates the adjustment component. Due to the unfamiliar use of the examinee, there is unnecessary communication. Working like this for a long time causes a communication burden and affects the efficiency of eye alignment adjustment. Therefore, an improvement is urgently needed. Therefore, we propose a supporting and assisting mechanism for ophthalmic medical optometry. Content of the Utility Model
[0004] The purpose of the present utility model is to provide a supporting and assisting mechanism for ophthalmic medical optometry, which solves the problems mentioned in the background technique.
[0005] To achieve the above purpose, the present utility model provides the following technical solution: A supporting and assisting mechanism for ophthalmic medical optometry, including a base, a support platform is placed at the rear side of the middle part of the base, a frame is fixedly installed at the rear side of the support platform, and an electric controller is placed at one side of the top of the base;
[0006] A strip-shaped opening is formed in the middle of the rear wall of the base, and a guide block is movably clamped in the strip-shaped opening;
[0007] A forward and reverse motor is fixedly installed on one side of the base, a screw rod is fixedly installed at the inner end of the transmission shaft of the forward and reverse motor, the screw rod is screwed with the guide block through a threaded hole, and the inner end of the screw rod is rotatably connected to the base through a bearing;
[0008] The rear side of the guide block is fixedly connected to the support platform, a rectangular block is installed at the inner top of the support platform, and a support plate is fixedly installed on the top of the rectangular block;
[0009] A forehead groove is formed in the front side of the top wall of the frame, and rubber pads are fixedly installed in the forehead groove and on the top of the support plate;

During the use of the supporting and assisting mechanism for ophthalmic medical optometry, after the examiner's head is placed, the doctor can drive the screw rod to rotate by reversing the motor, so that the guide block and the abutment move horizontally to adjust the horizontal position of the examiner's head. At the same time, the servo motor can drive the threaded column to rotate, which can drive the long block to move vertically to adjust the height of the head. This can reduce unnecessary communication and reduce the work burden, and this method makes the eye adjustment more efficient.
[0011] As an optional solution of the technical solution of the present application, the signal output end of the electronic controller is respectively connected to the signal input ends of the forward and reverse motor and the servo motor. Suction cups are fixedly installed at the four corners of the electronic controller, and a one-way air valve is integrally formed and communicated on the suction cup. Components such as the electronic controller and the suction cup can be used in cooperation. The electronic controller can be placed on the other side of the optometry instrument in the doctor's operation area and close to the doctor's hand position, which is convenient for improving the handy adjustment. And it is adsorbed by the suction cup to avoid the high-altitude drop of the electronic controller caused by collision. During the non-use period, force is applied to disassemble the electronic controller for its safe storage. It is relatively flexible to use and has strong practicability.

A wire hole is opened on the lower side of the rear wall of the abutment close to the heat dissipation holes. Air can flow through the multiple groups of heat dissipation holes, which is beneficial to the heat dissipation of the internal components. At the same time, the wire hole supplies the connecting wires for the internal and external components.
[0013] As an optional solution of the technical solution of the present application, ear plates are fixedly installed at the four corners of the base, and positioning holes are opened in the middle of the ear plates. The base can be detachably fixed through the ear plates and the positioning holes to ensure the stability of its limit and support the later-stage displacement and replacement.
