Description

Technical Field

[0001] This utility model belongs to the field of display screen technology, and in particular relates to an installation and fixing device and display screen suitable for various types of display screen cabinets. Background Technology

[0002] In the field of display technology, curved and irregularly shaped displays are increasingly used in various scenarios, such as commercial displays, immersive experience spaces, and stage performances. The flexibility and stability of their splicing and installation have become technical challenges. Traditional connection solutions for curved displays have the following limitations:

[0003] In existing technologies, curved displays are often spliced ​​by setting a chamfered edge on the connecting side of the cabinet frame and using a curvature lock (such as in patent application CN202223488589.3). This solution relies on a pre-processed chamfered edge angle and can only accommodate splicing requirements for a single curvature. If the curvature or splicing angle needs to be adjusted, the chamfered edge structure must be customized, resulting in poor versatility and high cost. In addition, using a dedicated curvature locking device to fix adjacent cabinets increases production costs.

[0004] Based on this, the present invention provides a novel installation and fixing device and display screen applicable to various types of display screen cabinets, in order to overcome the above-mentioned defects. Utility Model Content

[0005] One objective of this utility model is to provide an installation and fixing device suitable for various types of display screen cabinets. When using this installation and fixing device, the user can directly and manually rotate the first corner fastener and the second corner fastener according to the splicing requirements of the display screen cabinet, and adjust the two to a preset relative angle, so as to meet the splicing requirements of irregularly shaped display screen cabinets such as arc and wave.

[0006] This utility model adopts the following technical solution: a mounting and fixing device suitable for various types of display screen cabinets, the mounting and fixing device having a first mounting surface and a second mounting surface; the mounting and fixing device includes a first corner fastener, a second corner fastener, a first connecting screw and a second connecting screw;

[0007] The first corner fastener and the second corner fastener are hinged together by a connecting shaft, allowing them to rotate relative to each other around the connecting shaft. The first corner fastener has at least two first mounting holes, and the first connecting screw passes through the first mounting holes and extends out of the first mounting surface to be threadedly connected to the first display screen housing. The second corner fastener has at least two second mounting holes, and the second connecting screw passes through the second mounting holes and extends out of the first mounting surface to be threadedly connected to the second display screen housing.

[0008] Furthermore, both the first mounting hole and the second mounting hole are elongated holes used to adjust the mounting positions of the first connecting screw and the second connecting screw.

[0009] Furthermore, the connecting shaft is also provided with a damping structure, which is installed in the hinge holes of the first corner clip and the second corner clip, and acts on the connecting shaft to maintain the relative angle between the first corner clip and the second corner clip.

[0010] Furthermore, the connecting shaft is also provided with a damping structure, which is located at the connecting shaft and acts on the hinge holes of the first corner fastener and the second corner fastener to maintain the relative angle between the first corner fastener and the second corner fastener.

[0011] Furthermore, the connecting shaft is a damped hand-twist shaft, and one end of the hand-twist shaft is provided with a knob. Rotating the knob can adjust the magnitude of the pre-tightening force between the hand-twist shaft and the first and second corner fasteners.

[0012] Furthermore, the mounting and fixing device also includes a snap-fit ​​component, which is fixedly mounted on the second mounting surface of the mounting and fixing device.

[0013] Furthermore, the snap-fit ​​component includes a base plate, a first vertical plate and a second vertical plate perpendicularly disposed on both sides of the base plate, the free ends of the first vertical plate and the second vertical plate extending outward to form a first connecting wing and a second connecting wing, respectively; at least one third mounting hole is provided on the first connecting wing and the second connecting wing, and a locking member is inserted through the third mounting hole to fix the snap-fit ​​component to the second mounting surface.

[0014] Furthermore, the substrate has a padding layer on the side facing the second mounting surface.

[0015] Furthermore, the locking component is a third connecting screw, which passes through the third mounting hole and extends out of the first mounting surface to be threadedly connected to the display screen housing.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model provides an installation and fixing device applicable to various types of display screen cabinets, offering convenient and flexible operation during actual installation. Users can manually rotate the first and second corner clips to adjust them to a preset relative angle according to the display screen cabinet splicing requirements. After angle adjustment, the first connecting screw passes through the first mounting hole on the first corner clip and is screwed into the threaded hole of the first display screen cabinet; simultaneously, the second connecting screw passes through the second mounting hole on the second corner clip and is screwed into the threaded hole of the second display screen cabinet. By tightening the two connecting screws, the first mounting surface can tightly fit against the cabinet frame, thereby achieving a stable connection between the first and second display screen cabinets. The installation process is simple, requiring no edge trimming, greatly improving installation efficiency.

[0018] Based on the design of the connecting shaft, the mounting and fixing device can achieve stepless adjustment of the first and second corner fasteners within a certain angle range. This allows the mounting and fixing device to not only meet the splicing needs of irregularly shaped display cabinets with different curvatures, such as arcs and waves, but also to handle the splicing between flat display cabinets.

Detailed Implementation

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] The following is in conjunction with the appendix Figure 1 To be continued Figure 3 The present invention will be described in detail with reference to specific embodiments:

[0027] like Figures 1 to 3 As shown, this utility model provides an installation and fixing device suitable for various types of display screen cabinets. The installation and fixing device has a first mounting surface 2 and a second mounting surface 3 facing each other. The installation and fixing device includes a first corner fastener 4, a second corner fastener 5, a first connecting screw 6, and a second connecting screw 7.

[0028] The first corner fastener 4 and the second corner fastener 5 are hinged together by a connecting shaft 8, allowing them to rotate relative to each other around the axis of the connecting shaft 8 to accommodate the splicing angle requirements of adjacent display screen cabinets. The first corner fastener 4 has at least two first mounting holes 40, and the first connecting screw 6 passes through the first mounting holes 40 and extends out of the first mounting surface 2 to be threadedly connected to the first display screen cabinet. The second corner fastener 5 has at least two second mounting holes 50, and the second connecting screw 7 passes through the second mounting holes 50 and extends out of the first mounting surface 2 to be threadedly connected to the second display screen cabinet.

[0029] This utility model provides an installation and fixing device applicable to various types of display screen cabinets, offering convenient and flexible operation during actual installation. Users can manually rotate the first corner bracket 4 and the second corner bracket 5 to adjust them to a preset relative angle according to the display screen cabinet splicing requirements. After angle adjustment, the first connecting screw 6 passes through the first mounting hole 40 on the first corner bracket 4 and is screwed into the threaded hole of the first display screen cabinet; simultaneously, the second connecting screw 7 passes through the second mounting hole 50 of the second corner bracket 5 and is screwed into the threaded hole of the second display screen cabinet. By tightening the two connecting screws, the first mounting surface 2 can tightly fit against the cabinet frame, thereby achieving a stable connection between the first and second display screen cabinets. The installation process is simple, requiring no edge trimming, greatly improving installation efficiency.

[0030] Based on the design of the connecting shaft 8, the mounting and fixing device can achieve stepless adjustment of the first corner fastener 4 and the second corner fastener 5 within a certain angle range. This allows the mounting and fixing device to not only meet the splicing requirements of irregularly shaped display cabinets such as arc and wave shapes, but also to handle the splicing between flat display cabinets. It effectively solves the problem of limited adaptability of traditional mounting and fixing devices and significantly improves the flexibility and diversity of display splicing.

[0031] Furthermore, in some specific embodiments, both the first mounting hole 40 and the second mounting hole 50 are elongated holes, used to adjust the installation positions of the first connecting screw 6 and the second connecting screw 7 to adapt to installation requirements with different curvatures.

[0032] Furthermore, in some specific embodiments, the connecting shaft 8 is also provided with a damping structure.

[0033] The connecting shaft 8 is disposed through the hinge holes of the first corner fastener 4 and the second corner fastener 5, thereby realizing the hinged connection between the first corner fastener 4 and the second corner fastener 5.

[0034] Option 1 is as follows: The damping structure is installed in the hinge holes of the first corner clip 4 and the second corner clip 5, and acts on the connecting shaft 8 to maintain the relative angle between the first corner clip 4 and the second corner clip 5, increase the damping force between the first corner clip 4, the second corner clip 5 and the connecting shaft 8, and use the damping friction to prevent the first corner clip 4 and the second corner clip 5 from rotating accidentally, ensuring the stability of the adjusted angle and preventing the angle from shifting due to vibration or external force.

[0035] Option 2 involves a damping structure located at the connecting shaft 8, acting on the hinge holes of the first and second corner clips 4 and 5 to maintain the relative angle between them. This also increases the damping force between the first and second corner clips 4 and 5 and the connecting shaft 8, using damping friction to prevent accidental rotation of the first and second corner clips 4 and 5, ensuring the stability of the adjusted angle and preventing angle deviation due to vibration or external forces. The damping structure could be a damping sleeve made of damping material, fitted onto the outer wall of the connecting shaft 8, or the connecting shaft 8 could be directly made of damping material, simultaneously serving as both the connecting shaft 8 and the damping structure.

[0036] Option 3 is: Figure 2 As shown, the connecting shaft 8 is a damped hand-twist shaft. One end of the hand-twist shaft has a knob 80. Rotating the knob 80 adjusts the preload between the hand-twist shaft and the first and second snap-fit ​​members 4 and 5. Correspondingly, increasing the preload further locks the relative angle between the first and second snap-fit ​​members 4 and 5, preventing angular displacement due to vibration or external force. When the preload is reduced, the first and second snap-fit ​​members 4 and 5 can rotate freely, facilitating quick adjustment of their relative angle. It should be noted that the specific structure of the damped hand-twist shaft in this invention is not limited; it can be designed by those skilled in the art based on actual conditions, or existing technologies such as torsion spring damped shafts can be directly referenced.

[0037] Furthermore, in some specific embodiments, the mounting and fixing device further includes a snap-fit ​​component 9, which is fixedly installed on the second mounting surface 3 of the mounting and fixing device. The mounting and fixing device can be fixedly installed at a preset position on the fixing rod through the snap-fit ​​component 9, thereby realizing the fixed installation of the display screen cabinet.

[0038] The structural design of the snap-fit ​​component 9 in this utility model can be varied, such as a design similar to a clamp or a design similar to a snap-fit ​​gripper.

[0039] In this embodiment, as Figure 3As shown, the snap-fit ​​component 9 includes a base plate 90, a first vertical plate 91 and a second vertical plate 92 perpendicularly disposed on both sides of the base plate 90, forming a receiving cavity for accommodating the fixing rod. The free ends of the first vertical plate 91 and the second vertical plate 92 extend outward to form a first connecting wing 93 and a second connecting wing 94, respectively. At least one third mounting hole 95 is provided on each of the first connecting wing 93 and the second connecting wing 94. A locking member 96 passes through the third mounting hole 95 to fix the snap-fit ​​component 9 to the second mounting surface 3. A soft pad layer is provided on the side of the base plate 90 facing the second mounting surface 3 to increase the friction between it and the fixing rod. The locking member 96 can be a bolt, screw, or the like.

[0040] Furthermore, in some more specific embodiments, the locking member 96 is a third connecting screw, which passes through the third mounting hole 95 and extends out of the first mounting surface 2 to be threadedly connected to the corresponding display screen cabinet, thereby enhancing the installation stability of the display screen cabinet.

[0041] Based on the aforementioned mounting and fixing device applicable to various types of display screen cabinets, this utility model further provides a display screen, which includes several display screen cabinets and the aforementioned mounting and fixing device applicable to various types of display screen cabinets. One of two adjacent display screen cabinets is connected to a first corner fastener in the mounting and fixing device, and the other is connected to a second corner fastener in the mounting and fixing device. This utility model's display screen incorporates all the technical solutions of the aforementioned mounting and fixing device applicable to various types of display screen cabinets and possesses at least all the advantages of the aforementioned mounting and fixing device applicable to various types of display screen cabinets, which will not be elaborated further here.

[0042] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
