Description

Technical Field

[0001] The utility model relates to the technical field of screen installation, and particularly relates to a curved screen angle adjusting device. Background Art

[0002] The main advantages of a curved screen are to provide users with a better sense of immersion, be more in line with the viewing habits of the human eye, and have a wider viewing angle. Its installation angle is crucial for obtaining the best visual effect and viewing experience. According to different types of curved screens and usage scenarios, the requirements for the installation angle will vary.

[0003] Currently, the commonly used angle adjusting mechanism for curved screens mainly locks or clamps the product or the connecting mechanism from the side or the front. During the angle adjustment process, it is necessary to repeatedly squeeze the product or the connecting mechanism, which will cause certain damage to the product or the connecting mechanism, resulting in a poor user experience, poor adjustment accuracy, and a very large movement resistance at the locking mechanism for the purpose of locking. Generally, auxiliary tools are also required during angle adjustment.

[0004] Therefore, in view of the deficiencies of the existing technology, it is necessary to design a curved screen angle adjusting device to solve the above problems.

[0005] It should be noted that the above introduction of the technical background is only for the convenience of clearly and completely explaining the technical solution of the present utility model and facilitating the understanding of those skilled in the art. It cannot be considered that the above content is well-known to those skilled in the art just because these contents are described in the background art of the present utility model. Summary of the Utility Model

[0006] To overcome the above deficiencies in the prior art, the purpose of the present utility model is to disclose a curved screen angle adjusting device, which solves the problems that when the traditional curved screen angle adjusting mechanism locks the angle, the extrusion force on the curved screen or the connecting mechanism is too large, which is easy to cause damage, and the adjustment resistance is large and the angle fine-tuning is difficult.

[0007] The utility model discloses a curved screen angle adjusting device, which includes a screen connection block and a positioning base. The screen connection block includes a screen fixing plate for installing a curved screen, and an arc-shaped guide plate is arranged on the side of the screen fixing plate away from the curved screen; an arc-shaped guide groove is arranged on the positioning base, and the arc-shaped guide plate passes through the arc-shaped guide groove and is slidably connected therewith. The arc-shaped guide groove includes an inner guide arc surface close to the inner side surface of the arc-shaped guide plate and an outer guide arc surface close to the outer side surface of the arc-shaped guide plate. The distance between the inner guide arc surface and the outer guide arc surface is greater than the thickness of the arc-shaped guide plate. An adjusting screw is arranged on the lower side of the positioning base, and the front end of the adjusting screw can pass through the outer guide arc surface and abut against the outer side surface of the arc-shaped guide plate. By adjusting the screw, the movement track of the arc-shaped guide plate is changed, so that the friction force at the contact point between the arc-shaped guide plate and the positioning base is changed, and the arc-shaped guide plate and the curved screen thereon are restricted at different angles by using the change of the frictional resistance, thereby reducing the resistance during the angle adjustment of the curved screen.

[0008] Preferred technical solution: The positioning base includes a left guide device and a right guide device, and the left guide device and the right guide device are detachably connected by fasteners, which is convenient for the disassembly and assembly of the positioning base and the arc-shaped guide plate.

[0009] Preferred technical solution: The screen fixing plate is fixedly connected with the curved screen by a locking screw to ensure the connection stability.

[0010] Preferred technical solution: A rotating cap is arranged at one end of the adjusting screw away from the positioning base, which is convenient for adjusting the adjusting screw.

[0011] Preferred technical solution: A push head is arranged at the front end of the adjusting screw, and the front end of the push head is a profiling arc surface that can fit with the outer side surface of the arc-shaped guide plate, which increases the contact area and avoids damaging the arc-shaped guide plate during the adjustment process.

[0012] Preferred technical solution: The radian of the inner guide arc surface is the same as that of the arc-shaped guide plate, which increases the contact area between the two.

[0013] Due to the application of the above technical solutions, the beneficial effects of the utility model compared with the prior art are as follows:

[0014] The curved screen angle adjusting device of the utility model locks the angle of the curved screen through the friction force between the arc-shaped guide plate on the screen connection block and the arc-shaped guide groove on the positioning base. By adjusting the screw, the movement track of the arc-shaped guide plate is changed, so that the included angle between the gravity direction of the screen connection block and the curved screen thereon and the frictional resistance direction of the arc-shaped guide groove is changed. Furthermore, the screen connection block and the curved screen thereon can be locked at different angles, and the angle locking is realized by changing the friction force generated by the component force extrusion of the gravity of the screen connection block and the curved screen thereon at the connection surface. The upper limit of its resistance is controllable, the angle adjustment is smoother and more accurate, and it is not easy to damage the curved screen and its connecting parts.

[0029] Embodiment 1:

[0030] As Figure 1 and Figure 2As shown in the figure, the present utility model discloses a curved screen angle adjustment device, which includes a screen connection block 1 and a positioning base 2. The main components of the above-mentioned present utility model will be specifically described below:

[0031] As Figure 1 , Figure 2 and Figure 3 shown, the screen connection block 1 includes a screen fixing plate 11. The screen fixing plate 11 fixes the curved screen 3 through a locking screw 11a. An arc-shaped guide plate 12 is provided on the side of the screen fixing plate 11 away from the curved screen 3. The angle of the curved screen 3 is adjusted by connecting with the positioning base 2 through the arc-shaped guide plate 12.

[0032] As Figure 1 , Figure 2 and Figure 3 shown, an arc-shaped guide groove 21 is provided on the positioning base 2. The arc-shaped guide plate 12 passes through the arc-shaped guide groove 21 and is slidably connected therewith. The arc-shaped guide groove 21 includes an inner guide arc surface 21a close to the inner side surface 12a of the arc-shaped guide plate and an outer guide arc surface 21b close to the outer side surface 12b of the arc-shaped guide plate. The distance between the inner guide arc surface 21a and the outer guide arc surface 21b is greater than the thickness h of the arc-shaped guide plate, so that the arc-shaped guide plate 12 has a certain activity space in the arc-shaped guide groove 21; an adjusting screw 22 is provided on the lower side of the positioning base 2. The front end of the adjusting screw 22 can pass through the outer guide arc surface 21b and abut against the outer side surface of the arc-shaped guide plate 12.

[0033] The usage method and principle of the present utility model are as follows:

[0034] As Figure 4 shown, when the curved screen needs to be in an elevation angle, the adjusting screw 22 is completely withdrawn. At this time, the movement track of the arc-shaped guide plate 12 remains unchanged, and the friction force received is the smallest. Under the action of the gravity of the curved screen 3, it can easily slide downward with the arc-shaped guide plate 12, so that the curved screen 3 is placed in an elevation angle state.

[0035] As Figure 5 shown, when the curved screen needs to be vertical, the adjusting screw 22 is partially screwed in. At this time, the movement track of the arc-shaped guide plate 12 is changed under the action of the adjusting screw 22. The mutual acting force between the adjusting screw 22 and the arc-shaped guide plate 12 increases, so that the frictional resistance received by the arc-shaped guide plate 12 increases, and the resistance of the arc-shaped guide plate 12 to slide downward increases. Furthermore, when the arc-shaped guide plate 12 slides downward until the curved screen is in a vertical state, it can stop under the action of the frictional resistance.

[0036] As Figure 6As shown, when the curved screen needs to be at a depression angle, the adjusting screw 22 is fully screwed in. At this time, the movement trajectory of the arc-shaped guide plate 12 is completely changed, and the friction force between the arc-shaped guide plate 12 and the adjusting screw 22 reaches the maximum. When the curved screen is at an elevation angle, the arc-shaped guide plate 12 can pause under the action of the friction force.

[0037] The above operation is based on changing the movement trajectory of the arc-shaped guide plate 12 to change the friction force it receives. The principle is to utilize the change in the contact angle between the gravity of the arc-shaped guide plate 12 and the curved screen 3 and the arc-shaped guide groove 21 and the adjusting screw 22 to change the component force of gravity at the contact surface, thereby changing the frictional resistance received by the arc-shaped guide plate 12. Since the generation of the frictional resistance mainly utilizes the gravity of the arc-shaped guide plate 12 and the curved screen 3 and the upper limit of the frictional resistance is controllable, the resistance received during the angle adjustment of the arc-shaped guide plate 12 and the curved screen 3 is limited, the feel is relatively compliant, it is convenient for fine adjustment, and it is not easy to damage the curved screen and its connectors.

[0038] It should be noted that the complete withdrawal, partial screwing in, and full screwing in of the above-mentioned adjusting screw 22 are only for the convenience of operators to operate. Slight deviations during actual operation do not affect the final effect.

[0039] Embodiment 2:

[0040] As Figure 1 、 Figure 2 and Figure 3 shown, for the convenience of assembling the screen connection block 1 and the positioning base 2, the positioning base 2 includes a left guiding device 2a and a right guiding device 2b that are detachably connected, and the left guiding device 2a and the right guiding device 2b are detachably connected by a fastener 23. During use, the arc-shaped guide plate 12 is placed in the left guiding device 2a, and then the right guiding device 2b is assembled so that the arc-shaped guide plate 12 is in the arc-shaped guide groove 21.

[0041] Embodiment 3:

[0042] As Figure 1 、 Figure 2 and Figure 3 shown, for the convenience of adjusting the movement trajectory of the arc-shaped guide plate 12, a rotating cap 22a is provided at one end of the adjusting screw 22 away from the positioning base 2 to reduce the difficulty of adjusting the adjusting screw 22 through the rotating cap 22a.

[0043] Embodiment 4:

[0044] As Figure 1 、 Figure 2 and Figure 3As shown, in order to further prevent damage to the arc-shaped guide plate 12, a push head 22b is provided at the front end of the adjusting screw 22. The front end of the push head 22b is a profiling arc surface that can fit against the outer side surface of the arc-shaped guide plate 12, increasing the contact area between the adjusting screw 22 and the arc-shaped guide plate 12 and reducing the possibility of the arc-shaped guide plate 12 being damaged by extrusion.

[0045] Embodiment Five:

[0046] As Figure 1 、 Figure 2 and Figure 3 shown, in order to increase the frictional force between the arc-shaped guide plate 12 and the arc-shaped guide groove 21, the radian of the inner guide arc surface 21a is the same as that of the arc-shaped guide plate 12. Under the push of the adjusting screw 22, the arc-shaped guide plate 12 can fit completely against the inner guide arc surface 21a, increasing the frictional force.

[0047] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
