Embodiment 1

[0021] Such as figure 1 and figure 2 As shown, a crack ruler that is convenient for viewing angle adjustment includes a strip slide rail 1, a visual target plate 3 and an orifice plate 2 arranged on the strip slide rail 1, a base 9 and a base 9 and a strip slide rail 1. The connection part of the connection, the connection part includes a support rod 4, a threaded seat 6, a threaded column 5, a ball joint seat 8 and a ball joint part 7 arranged on the ball joint seat 8;

[0022] The two ends of described support rod 4 are respectively connected on the base 9 and the strip slide rail 1, and the connection relation of any one end of support rod 4 is hinged connection, and the connection relation of the other end is fixed connection, and threaded seat 6 is fixed on the base 9, the lower end of the threaded column 5 is threadedly connected to the threaded seat 6, the upper end of the threaded column 5 is connected to the ball joint 7, and the ball joint 8 is hingedly connected t...

Embodiment 2

[0026] The present embodiment is further limited on the basis of embodiment 1, as figure 1 As shown, the holes on the orifice plate 2 are single holes or double holes in order to facilitate the realization of collective function training or dispersal function training.

[0027] For the convenience of judging and regularizing different training intensities, the bar-shaped slide rail 1 is also provided with a scale along the length direction of the bar-shaped slide rail 1 .

[0028] In order to make the present invention have a larger adjustment range and not expose too many threads of the threaded post 5, the threaded seat 6 is cylindrical, and the threaded connection point between the threaded seat 6 and the threaded post 5 is located at the center of the threaded seat 6. upper end.

[0029] In order to avoid or reduce the harm to children caused by children hitting the front end of the bar-shaped slide rail 1 during the training process, the front end of the bar-shaped slide...

Abstract

The invention discloses an aperture rule facilitating adjustment of an observation angle. The aperture rule comprises a strip-shaped sliding rail, a sighting mark plate, a pore plate, a pedestal and a connecting portion, wherein the sighting mark plate and the pore plate are arranged on the strip-shaped guide sliding rail, and the pedestal is connected with the strip-shaped sliding rail through the connecting portion. The connecting portion comprises a supporting rod, a thread base, a thread post, a ball connection base and a ball connection portion which is arranged on the ball connection base. The two ends of the supporting rod are connected with the pedestal and the strip-shaped sliding rail respectively, one end of the supporting rod is in hinged connection, the other end of the supporting rod is in fixed connection, the thread base is fixed on the pedestal, the lower end of the thread post is in thread connection with the thread base, the upper end of the thread post is connected with the ball connection portion, and the ball connection base is in hinged connection with the strip-shaped sliding rail. The ball connection portion comprises a ball shell and a rolling ball arranged in the ball shell, the thread post is fixed on the rolling ball, and the ball shell is further provided with a strip-shaped hole adapting to the inclination direction of the strip-shaped sliding rail. The inclination angle of the strip-shaped sliding rail is convenient to adjust.

Description

technical field [0001] The invention relates to the field of vision training equipment, in particular to a slit ruler which is convenient for viewing angle adjustment. Background technique [0002] Stereo vision is an advanced visual function of humans and higher animals. The restoration and reconstruction of stereo vision function after strabismus surgery has been paid more and more attention by ophthalmologists, and it is also an important indicator for evaluating the cure of strabismus. Therefore, the treatment of strabismus is not only the correction of eye position, but more importantly, the recovery of binocular vision after strabismus surgery. In the prior art, the gap ruler trainer is widely used in the recovery of binocular visual function after intermittent exotropia in children. [0003] The average age of the above children who use the gap gauge trainer is under 10 years old, and the gap gauge of the prior art includes a base, a strip slide rail, a visual target...
