Description

Technical Field

[0001] The utility model belongs to the technical field of liquid crystal splicing screens, and in particular relates to an adjustable liquid crystal splicing screen. Background Art

[0002] As an important application of LCD display screens, LCD splicing screens are widely used in dispatching command centers, shopping malls, security monitoring and exhibitions. They can be used as a single display or spliced ​​into an ultra-large screen. The modular design can be used according to different usage requirements to achieve a large-screen function that can be enlarged or reduced. The image has a variety of display methods, which can be displayed in single-screen split display, single-screen display, any combination of display, full-screen LCD splicing, double-spliced ​​LCD screen splicing or vertical screen display, etc. It supports roaming, zooming and stretching of digital signals, cross-screen display, setting and running of various display plans, and real-time processing of full HD signals. In real life, according to the installation environment or personal needs, the splicing methods of LCD splicing screens include flat splicing, curved splicing and various creative special-shaped splicing, etc. The two sides of the splicing screen in real life are usually rectangular, but there are also splicing screens with inclined surfaces on both sides.

[0003] In the prior art, the curved surface liquid crystal splicing screen connection angle adjustment mechanism with publication number CN218844825U is provided with angle plate 2 on the right side of angle plate 1, angle plate 1 and angle plate 2 are hinged by a pin shaft, and liquid crystal screen 1 is installed on the outer surface of angle plate 1 by two bolts, and liquid crystal screen 2 is installed on the outer surface of angle plate 2 by two bolts. The utility model can conveniently connect liquid crystal screen 1 and liquid crystal screen 2, splicing the liquid crystal screens into a curved screen for use, and using the adjustment component, it is convenient to adjust the angle between liquid crystal screen 1 and liquid crystal screen 2, so that the device can adjust the connection angle of the curved surface liquid crystal splicing screen, and can improve the use effect of the curved liquid crystal splicing screen.

[0004] However, there are still certain deficiencies in the prior art: in the above structure, the angle between the LCD screens can be adjusted by adjusting the components, so that the image surfaces of several LCD screens can be formed into concave arc surfaces, and due to the limitation of the adjustment components, only concave arc surfaces can be formed in the end, but in real life, due to environmental requirements or personal needs, the curved splicing screen has not only concave arc surfaces but also convex arc surfaces, so the structure of the above prior art can only adapt to the angle adjustment of one arc surface, and thus cannot adapt to all situations of the curved splicing screen, which needs further improvement. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides an adjustable liquid crystal splicing screen, so that the entire liquid crystal splicing screen can be adjusted to an inwardly concave arc surface type or an outwardly convex arc surface type, and the gap change between the splicing screens when adjusting the angle thereof is reduced to prevent the gap from becoming larger after the angle adjustment.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable liquid crystal splicing screen, comprising a base, a middle splicing screen and a side splicing screen, wherein the middle splicing screen and the side splicing screen are exactly the same, and further comprising: a boss, arranged on the top surface of the base; a guide rod 1, arranged on the top surface of the base; an arc-shaped slider, slidably arranged on the base and having an arc-shaped sliding track; a limit groove 2, arranged on the outer end of the arc-shaped slider; a guide rod 2, detachably arranged on the arc-shaped slider; a support ring, arranged on the guide rod 1 and the guide rod 2; a connecting piece, arranged on the back of the middle splicing screen and the side splicing screen and can be sleeved on the guide rod 1 and the guide rod 2.

[0007] Optionally, it also includes: a boss, which is arranged on the base; a plurality of limit grooves, which are arranged on the base at equal angles and are coaxial with the sliding trajectory of the arc-shaped slider; a circular hole, which is arranged on the base and is the center of the sliding trajectory of the arc-shaped slider; an extension rod, which is detachably arranged on the top of the guide rod one or the guide rod two; a limit nut, which is detachably arranged on the top of the guide rod one, the guide rod two and the extension rod; and a limit piece, which can be inserted into the limit groove one and the limit groove two.

[0008] Optionally, the guide rod 1 is located on an extended track of the arc-shaped sliding block, thereby ensuring that the two connecting pieces on each spliced ​​screen are in the same position, thereby facilitating the installation of the connecting pieces on each spliced ​​screen.

[0009] Optionally, one of the limit grooves 1 represents 0°, so that different arc-shaped splicing screen effects can be achieved by sliding the arc-shaped slider in different directions with the limit groove 1 representing 0° as the boundary, and when the limit groove 2 on the arc-shaped slider is aligned with the limit groove 1 representing 0°, the guide rod 2 and the guide rod 1 on the arc-shaped slider are on the same horizontal line, thereby ensuring that the two connecting parts on each splicing screen are at the same distance from the two sides of the splicing screen and the required specifications of the connecting parts are the same, thereby facilitating the installation of the connecting parts on each splicing screen.

[0010] Optionally, the left and right sides of the middle splicing screen and the side splicing screen are both inwardly inclined surfaces, and the narrower surface is the back surface, thereby providing adjustment space when the splicing screen angle is adjusted to an outward convex arc surface, and also facilitating the relative angle rotation between the splicing screens.

[0011] Optionally, when guide rod 2 is arranged on the arc-shaped slider, the support ring on guide rod 2 is at the same height as the support ring on guide rod 1, so that the splicing screen is horizontal when placed on the two support rings, and the two connecting parts are symmetrically horizontal when fixed to the back of the splicing screen (that is, ensuring that the two connecting parts are installed at the same height on the splicing screen), which facilitates determining the installation position of the connecting parts.

[0012] Optionally, after the middle splicing screen or the side splicing screen is installed, the vertical directions of both side edges thereof will be aligned with the centers of the circular holes on the two side bases respectively, so that when the angles of adjacent splicing screens are adjusted, they are rotated around the intersection line as the axis, thereby ensuring that the gap between adjacent splicing screens will not be increased when the angle is adjusted, thereby always ensuring the viewing effect.

[0013] In summary, this application has the following beneficial effects:

[0014] The present application is provided with a base, a boss, a guide rod 1, an arc-shaped slide groove, an arc-shaped slider, a limit groove 1, a limit groove 2, a limit piece, a guide rod 2, a support ring, a connecting piece, a round hole, an extension rod, and a limit bolt. The middle splicing screen and the side splicing screen are installed by the cooperation of the base, the boss, the guide rod 1, the arc-shaped slide groove, the arc-shaped slider, the limit groove 1, the limit groove 2, the limit piece, the guide rod 2, the support ring, the connecting piece, the round hole, the extension rod, and the limit bolt. During the installation process, the angle of the adjacent splicing screens can be adjusted by sliding the position of the arc-shaped slider. In addition, the side surface of the splicing screen is an inwardly inclined surface, so that the overall splicing screen can be adjusted to an inner concave arc surface type, an outer convex arc surface type, and a commonly used flat type, so that the device has a wider applicable environment and is more practical.

[0015] All the spliced ​​screens in the present application are in contact with each other, so that after the spliced ​​screens are installed as a whole, the gaps between adjacent spliced ​​screens are very small, which improves the viewing effect of the spliced ​​screens, and when the angles of adjacent spliced ​​screens are adjusted, the adjustment is made with the intersecting sides as the axis, so that when the device adjusts the angle again, no additional gaps will appear between adjacent spliced ​​screens, so that no matter how the angle is adjusted, the viewing effect can be ensured, which is more practical.

[0016] The structure of the present invention is simple, and is convenient for production and manufacturing in real life. Moreover, most of the parts can be disassembled and installed, which is convenient for transportation and more practical. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0032] refer to Figure 1-8, an adjustable liquid crystal splicing screen, including a base 1, the base 1 provides a supporting chassis and an installation plane, a boss 2 is fixedly arranged on one side of the top surface of the base 1, the boss 2 supports and stabilizes the bottom splicing screen, a guide rod 3 is fixedly arranged on the top surface of the base 1, the guide rod 3 provides an installation surface and a limit guide, an arc-shaped slide groove 4 is opened on the other side of the top surface of the base 1, the arc-shaped slide groove 4 provides an angled sliding space, an arc-shaped slider 5 is slidably arranged in the arc-shaped slide groove 4, a plurality of limit grooves 6 are opened at equal angles on the top surface of the base 1, and the plurality of limit grooves 6 are evenly distributed along the periphery of the arc-shaped slide groove 4, so that the limit groove 6 is equivalent to the angle prompt of the arc-shaped slider 5 sliding along the arc-shaped slide groove 4, which is convenient for clarifying the sliding angle of the arc-shaped slider 5;

[0033] refer to Figure 1-5 The outer end of the arc-shaped slider 5 is provided with a second limiting groove 7 adapted to the size of the first limiting groove 6, and the limiting member 8 can be inserted into the first limiting groove 6 and the second limiting groove 7, so that the limiting member 8 can be inserted into the second limiting groove 7 and one of the limiting grooves 4 at the same time, and then the arc-shaped slider 5 can be limited and stabilized at different positions, so as to ensure that the adjusted angle will not change, thereby ensuring the stability after adjustment;

[0034] The top surface of the arc-shaped slider 5 is threaded with a guide rod 2 9, and the guide rod 1 3 is located on the extension track of the arc-shaped slide groove 4 (this is the limit condition 1);

[0035] refer to Figure 2-4 , one of the limit slots 6 represents 0° (as shown in the attached Figure 3 As shown), the limit groove 6 indicating 0° can be used as a boundary, and different arc splicing screen effects can be achieved by sliding the arc slider 5 in different directions, that is, sliding the arc slider 5 in a direction away from the guide rod 3 can achieve an inner concave arc splicing screen, and sliding the arc slider 5 in a direction close to the guide rod 3 can achieve an outer convex arc splicing screen. When the arc slider 5 is in the 0° limit groove 6, a flat splicing screen can be achieved;

[0036] When the upper limit groove 2 7 on the arc-shaped slider 5 is aligned with the limit groove 1 6 indicating 0°, the guide rod 2 9 on the arc-shaped slider 5 and the guide rod 1 3 are on the same horizontal line (this is the second limit condition);

[0037] refer to Figure 1 , 46. A support ring 10 is sleeved and fixedly provided on both the guide rod 2 9 and the guide rod 1 3. The support ring 10 is used to cooperate with the boss 2 to provide support for the bottom splicing screen to ensure the overall stability of the splicing screen. A connecting piece 11 is sleeved and slidably provided on the guide rod 1 3 and the guide rod 2 9 above the support ring 10. The connecting piece 11 is used for connection. The side of the connecting piece 11 on the guide rod 1 3 is fixedly provided with a middle splicing screen 12 by bolts. The connecting piece 11 on the guide rod 2 9 is fixedly provided with a side splicing screen 13 by bolts. A circular hole 14 is opened on the top surface of the base 1 at the center of the arc-shaped slide groove 4. The circular hole 14 is used for position judgment;

[0038] refer to Figure 2 The left and right sides of the middle splicing screen 12 and the side splicing screen 13 are both inwardly inclined surfaces (i.e., the cross section is an isosceles trapezoid, and the narrower surface is the back surface), so that when the side splicing screen 13 deflects downward relative to the middle splicing screen 12, the intersection of the two will not separate, that is, no gap will be generated, and then after the splicing screen angle is adjusted, the viewing effect will not be affected;

[0039] refer to Figure 1 , 4 , 6-8, the top surfaces of the guide rod 1 3 and the guide rod 2 9 can be threadedly matched with an extension rod 15, and the two extension rods 15 can also be connected together by threading to form a longer extension rod 15. The extension rod 15 is used to provide installation and limit for the continued stacking of spliced ​​screens in the vertical direction, and it is also convenient for the stacking of spliced ​​screens in the vertical direction. The top of the extension rod 15, the guide rod 1 3 and the top of the guide rod 2 9 can also be threadedly matched with a limiting nut 16. The limiting nut 16 is used to limit and stabilize the top layer of the spliced ​​screen, thereby ensuring the overall stability of the spliced ​​screen.

[0040] When the splicing screen needs to be assembled, the installation steps are as follows: first, install the bottom layer of the splicing screen, and the bottom layer is installed from the middle to both sides; then install it upward layer by layer.

[0041] The specific installation steps are as follows:

[0042] First, two connectors 11 are fixed at corresponding positions on the back of the middle splicing screen 12 and the side splicing screen 13 by bolts. After the connectors 11 are installed, two bases 1 are placed horizontally and symmetrically on the ground, and then the middle splicing screen 12 is taken out, so that the two connectors 11 on the middle splicing screen 12 are respectively sleeved on the guide rods 3 on both sides, and finally the bottom surface of the connector 11 is in contact with the top surface of the support ring 10. At the same time, the bottom surface of the middle splicing screen 12 will contact the top surface of the boss 2, so that the middle splicing screen 12 is placed stably. At this time, the vertical directions of the two sides of the middle splicing screen 12 will be aligned with the centers of the circular holes 14 on the bases 1 on both sides (this is the limit condition four);

[0043] After the middle splicing screen 12 of the bottom layer is installed, the side splicing screens 13 are installed on both sides of the middle splicing screen 12. Take the installation of the side splicing screen 13 on the left side as an example: first, screw the guide rod 2 9 into the arc-shaped slider 5 on the base 1 on the left side of the middle splicing screen 12. When the guide rod 2 9 is completely screwed into the arc-shaped slider 5, the support ring 10 on the guide rod 2 9 is at the same height as the support ring 10 on the guide rod 1 3 (this is the third limit condition). Then, place another base 1 on the left side of the base 1 on the left side of the middle splicing screen 12. It is particularly noted that the base 1 and the base 1 on the left side of the middle splicing screen 12 are facing each other. The two connecting pieces 11 on the back of the side splicing screen 13 are respectively sleeved on the guide rod 2 9 and the guide rod 1 3, and finally the bottom surface of the connecting piece 11 contacts the top surface of the support ring 10. At the same time, the right side of the side splicing screen 13 contacts and aligns with the left side of the middle splicing screen 12 (similarly, the vertical directions of the two sides of the side splicing screen 13 are respectively aligned with the centers of the circular holes 14 on the two side bases 1), and then other side splicing screens 13 are installed to the left of the side splicing screen 13 in the same way;

[0044] (In the above content, through the cooperation of limiting conditions 1, 2, 3 and 4, the installation positions of the two connectors 11 on the back of the middle splicing screen 12 or the side splicing screen 13 are finally symmetrical, that is, the heights of the two connectors 11 and the distances from the two sides of the splicing screen are the same, and the connectors 11 required for all splicing screens are of the same specification, which facilitates the installation of the connectors 11 of all splicing screens)

[0045] After the side splicing screen 13 on the left side of the middle splicing screen 12 is installed, when the side splicing screen 13 needs to be installed on the right side of the middle splicing screen 12, the installation method of the side splicing screen 13 on the right side is basically the same as that on the left side. The only difference is that when placing another base 1, the orientation of the base 1 is the same as that of the base 1 on the right side of the middle splicing screen 12 (that is, the arc-shaped slide grooves 4 on the base 1 are all on the right side). After the side splicing screen 13 on the right side of the middle splicing screen 12 is also installed, the bottom layer of the splicing screen is installed;

[0046] After the bottom layer of the spliced ​​screen is installed, when the spliced ​​screen is installed in the vertical direction, first, the extension rods 15 are threadedly matched on the plurality of guide rods 13 and the guide rods, and then the two connecting pieces 11 on the middle spliced ​​screen 12 or the side spliced ​​screen 13 are sleeved on the two extension rods 15 at the corresponding positions of the bottom spliced ​​screen. At this time, the second layer of the spliced ​​screen is installed. When more layers of spliced ​​screens need to be added upward, it is only necessary to install the extension rods 15 and the spliced ​​screens in the same way on the plurality of extension rods 15. When the top layer of the spliced ​​screen is installed, the limiting nut 16 is screwed into the uppermost extension rod 15, so that the bottom surface of the limiting nut 16 contacts the bottom surface of the connecting piece 11 on the top layer of the spliced ​​screen for limiting, thereby stabilizing the spliced ​​screen as a whole to prevent shaking or swaying.

[0047] When the spliced ​​screen needs to be in a vertical plane as a whole, when installing the bottom side spliced ​​screen 13, move the limit groove 27 of the arc-shaped slider 5 on all the bases 1 to the limit groove 16 indicating 0° among the plurality of limit grooves 16, and then insert the limit member 8 into the limit groove 27 and the limit groove 16, so as to stabilize the position of the guide rod 29 (it should be noted that the position adjustment limit of the arc-shaped slider 5 is adjusted while the side spliced ​​screen 13 is installed in sequence, not after the bottom spliced ​​screen is installed). At this time, the guide rod 29 is on the same horizontal line with the guide rod, so that the front side surfaces (i.e., the image surface) of the two adjacent spliced ​​screens are in the same vertical plane, and then when all the spliced ​​screens are installed in this way, the front side surfaces (i.e., the image surface) of all the spliced ​​screens are in a vertical plane as a whole (the overall effect is as shown in the attached figure). Figure 1-2 and attached Fig. 9 shown).

[0048] When the screen needs to be spliced ​​as a whole to present an inwardly concave arc surface, the difference from the above-mentioned vertical plane installation is that: when the side splicing screens 13 are installed one by one after the installation of the bottom middle splicing screen 12 is completed, the first side splicing screens 13 on both sides of the middle splicing screen 12 are installed and placed on the support ring 10, and the arc-shaped slider 5 below the middle splicing screen 12 is slid a certain angle in the direction away from the guide rod 3 with the limit groove 16 indicating 0° as the boundary, and then the limit member 8 is inserted into the limit groove 2 7 and the limit groove 1 6 after being rotated a certain angle, and the arc-shaped slider 5 below the middle splicing screen 12 is slid a certain angle in the direction away from the guide rod 3, and then the limit member 8 is inserted into the limit groove 2 7 and the limit groove 1 6 after being rotated a certain angle, and the arc-shaped slider 5 below the middle splicing screen 12 is slid a certain angle in the direction away from the guide rod 3, and then the limit member 8 is inserted into the limit groove 1 7 and the limit groove 1 6 after being rotated a certain angle, and the arc-shaped slider 5 below the middle splicing screen 12 is slid a certain angle in the direction away from the guide rod 3, and then ... When the slider 5 slides, the side splicing screen 13 and the base 1 on the other side thereof will be deflected by a corresponding angle away from the guide rod 3 with the circular hole 14 on the base 1 of the sliding arc slider 5 as the rotation center (the side of the middle splicing screen 12 is also the rotation center), and then the side splicing screen 13 on the outer side is operated as the above steps, so that the outer side surface (image surface) of the splicing screen at the bottom layer is a concave arc surface, and then the splicing screen is installed upward to obtain a splicing screen with an overall concave arc surface (the overall effect is as shown in the attached figure). Figure 10-11 shown).

[0049] When the screen needs to be spliced ​​with an overall convex arc surface, the difference from the concave arc surface installation is that when sliding the arc slider 5, it is slid toward the guide rod 3 at a certain angle with the limit groove 6 representing 0° as the boundary, and the other operations are the same (the overall effect is as shown in the attached figure). Figure 12-13 shown).

[0050] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0051] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0052] The above description shows and describes several preferred embodiments of the present application, but as mentioned above, it should be understood that the present application is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the application concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the present application, and should be within the scope of protection of the claims attached to the present application.
