It can be understood that the axes of the limiting hole 211 and the guiding hole 111 may be arranged in a same line, and both the limiting hole 211 and the guiding hole 111 may extend along the X direction, and the corresponding connecting member 310 is also arranged along the X direction, so that when the connecting member 310 moves, the size of the gap between the first display screen 100 and the second display screen 200 along the X direction is adjusted.

In some embodiments, the second end of the connecting member 310 at least partially extends from an end of the guiding hole 111 facing away from the limiting hole 211, the adjusting member 320 can abut against an end of the guiding hole 111 facing away from the limiting hole 211, and the adjusting member 320 is rotatably connected to the second end of the connecting member 310.

When the connecting member 310 is set, the connecting member 310 may sequentially pass through the guide hole 111 and the limiting hole 211, the first end of the connecting member 310 may be clamped with the limiting hole 211, and the second end of the connecting member 310 may move along the guide hole 111, that is, the connecting member 310 and the second display screen 200 may be relatively fixed, and the adjusting member 320 may prop against the first display screen 100 and push the first display screen 100 to move when being shifted, so that the first display screen 100 may move relative to the connecting member 310, that is, the first display screen 100 and the second display screen 200 move relative to each other, so as to adjust the distance between the first display screen 100 and the second display screen 200.

It should be noted that the adjusting element 320 and the connecting element 310 may be riveted by a pin 350, the end of the adjusting element 320 may be provided with a first mounting hole 322, the second end of the connecting element 310 may be provided with a second mounting hole 312, and the pin 350 may pass through the first mounting hole 322 and the second mounting hole 312 on the adjusting element 320 and the connecting element 310, so that the adjusting element 320 may rotate relative to the connecting element 310 by using the pin 350 as a rotation axis.

In addition, since the adjusting member 320 abuts against the outer end surface of the guide hole 111, and when the adjusting member 320 rotates relative to the connecting member 310, it is necessary to push the first display screen 100 to move relative to the connecting member 310, when the adjusting member 320 rotates, the distance between the rotation center of the adjusting member 320 and the end surface of the guide hole 111 needs to be changed, and this process can be realized by designing the profile structure of the adjusting member 320, which will be described below.

In a possible implementation manner, one end of the adjusting member 320 rotatably connected to the connecting member 310 has a mating surface 321, the mating surface 321 is at least partially disposed around a rotation center of the adjusting member 320, and a distance between the mating surface 321 and the rotation center gradually increases or gradually decreases along an extending direction of the mating surface 321.

It will be appreciated that the adjustment member 320 has a cam-like structure at the end connected to the connecting member 310, and the engagement surface 321 may be understood as a profile surface of the cam, and the profile curve of the cam may be gradually increased or decreased in distance from its base line.

The outer edge of one end of the guide portion 110, which is away from the limiting hole 211, has an abutting surface 112, that is, the end surface of the guide hole 111 facing the adjusting member 320 is the abutting surface 112, the engaging surface 321 abuts against the abutting surface 112, when the adjusting member 320 rotates, because the abutting position of the engaging surface 321 and the abutting surface 112 on the adjusting rotation gradually changes, the distance from the rotation center of the adjusting member 320 to the abutting surface 112 also gradually changes, so that the change of the relative position of the connecting member 310 and the guide hole 111 along the X direction is realized, and the stepless adjustment of the distance between the first display screen 100 and the second display screen 200 is realized.

In some embodiments, the contour shape of the engagement surface 321 conforms to an involute, taking the rotation stroke of the adjusting member 320 as 180 °, referring to fig. 9, when the initial position, i.e., the low position of the contour shape, the abutting position on the engagement surface 321 is at a distance L1 from the center of the first mounting hole 322, when the adjusting member 320 rotates 90 °, i.e., the middle position of the contour shape, the abutting position on the engagement surface 321 is at a distance L2 from the center of the first mounting hole 322, when the adjusting member 320 rotates 180 °, i.e., the high position of the contour shape, the abutting position on the engagement surface 321 is at a distance L3 from the center of the first mounting hole 322, and L1 < L2 < L3, for example, the value of L1 may be 5mm to 14mm, including but not limited to 5mm, 8mm, 10mm, 11.9mm, 14mm, and the value of L2 may be 15mm to 17mm, including but not limited to 15mm, 15.1mm, 16mm, and 16mm, 17mm, the value of L3 may be 18mm to 25mm, including but not limited to 18mm, 19mm, 21mm, and 25mm, and the specific values of L1, L2, and L3 are not limited in this application. In addition, the angle of the rotation stroke of the adjusting member 320 may also be other values, which is not limited in the embodiment of the present application, and the profile change of the matching surface 321 may adopt a similar rule, which is not described herein again.

It should be noted that, when the adjusting member 320 rotates relative to the connecting member 310, the engagement surface 321 slides relative to the abutting surface 112, and the surface-to-surface engagement ensures the smoothness of the distance adjustment between the first display screen 100 and the second display screen 200, thereby reducing the wear. In addition, the trend that the distance between the rotation center of the adjusting member 320 and the abutting surface 112 increases or decreases corresponds to the trend that the gap between the first display screen 100 and the second display screen 200 increases or decreases, for example, when the adjusting member 320 rotates clockwise, the abutting position between the engaging surface 321 and the abutting surface 112 moves from the lower part of the contour of the engaging surface 321 to the higher part, at this time, the distance between the rotation center of the adjusting member 320 and the abutting surface 112 increases, the distance between the first display screen 100 and the second display screen 200 decreases, and when the adjusting member 320 rotates counterclockwise, the distance between the first display screen 100 and the second display screen 200 increases in an opposite process, which is not described herein again.

In order to facilitate the user to rotate the adjusting member 320, the adjusting member 320 may be a handle structure, one end of the adjusting member 320 is rotatably connected to the connecting member, and the other end of the adjusting member 320 is used for hand holding and can be engaged with the locking member 330.

Referring to fig. 3 to 6, in a possible implementation manner, the locking member 330 may be an arc-shaped rack, the arc-shaped rack is located on the first display screen 100, and the arc-shaped rack is opposite to the guide hole 111, and when the adjusting member 320 rotates to different positions, the arc-shaped rack may correspond to and be fixed at different positions of the arc-shaped rack.

Wherein, the one end that regulating part 320 deviates from connecting piece 310 has joint portion 323, and the arc rack at least part encircles regulating part 320, and the arc rack has a plurality of joint teeth 331 that arrange along arc rack extending direction, and when regulating part 320 rotated to different positions for connecting piece 310, joint portion 323 and different joint teeth 331 joint.

For example, the clamping portion 323 may be a flange extending along the length direction of the adjusting member 320 on the adjusting member 320, and the flange may be clamped in the tooth slot of the clamping tooth 331.

The size of the angle of the arc-shaped rack may correspond to the angle of the rotation stroke of the adjusting member 320, for example, when the rotation stroke of the adjusting member 320 is 180 °, the size of the arc-shaped angle of the arc-shaped rack may be 180 ° or greater than 180 °, so as to ensure that the adjusting member 320 can be fixed when rotating to different positions of the stroke thereof, so as to achieve stepless adjustment of the distance between the first display screen 100 and the second display screen 200. The specific size and shape of the arc-shaped rack are not particularly limited in the embodiment of the application.

It will be understood by those skilled in the art that the locking member 330 may be integrally formed with the box structure on the first display screen 100, or may be connected to the first display screen 100 by welding, and the material of the locking member 330 may include, but is not limited to, metal, alloy, or plastic, such as iron, aluminum, and the like, and this is not limited in this embodiment of the present invention.

Referring to fig. 3 to 9, in a possible implementation manner, a limiting protrusion 212 may be disposed on an inner wall of the limiting hole 211, an annular limiting groove 311 is disposed at a first end of the connecting member 310, and the limiting protrusion 212 is clamped in the limiting groove 311, so as to prevent the connecting member 310 from coming off from the limiting groove 311, and because the limiting groove 311 is annular, the limiting protrusion 212 does not interfere with the rotation of the connecting member 310.

In addition, since the connection member 310 needs to be inserted into the position-limiting hole 211, in order to allow the surface connection member 310 to interfere with the position-limiting protrusion 212 during insertion, a tangent plane may be disposed at a side of the first end of the connection member 310, and a cross-sectional shape of a hole section of the position-limiting hole 211 at a corresponding position of the position-limiting protrusion 212 matches a cross-sectional shape of the first end of the connection member 310.

The tangent plane may form an avoiding step 313, the avoiding step 313 has a plurality of step surfaces 3131, and the step surface 3131 may be a plane surface, when the connecting member 310 is inserted into the limiting hole 211, the avoiding step 313 is opposite to the limiting protrusion 212, so that the thickness of the connecting member 310 along the direction perpendicular to the step surface 3131 is equal to or less than the aperture of the limiting hole 211 at the position of the limiting protrusion 212, and it is ensured that the connecting member 310 can be inserted into the limiting hole 211. The first end of the connector 310 may further be provided with a guide surface 314, and the guide surface 314 may be an arc surface inclined toward the center of the connector 310 with respect to the step surface 3131, and the guide surface 314 may serve as a guide when the connector 310 is plugged.

Wherein, different step surfaces 3131 may be located on different sides of the limiting groove 311, so as to ensure symmetry and stress balance of the whole limiting structure. After the connecting member 310 is inserted into the position where the limiting groove 311 is engaged with the limiting protrusion 212, the connecting member 310 can be rotated by a certain angle to dislocate the step surface 3131 with the limiting protrusion 212, so that the two side walls of the limiting groove 311 can abut against the two side walls of the limiting protrusion 212 to limit the connecting member 310.
