Description

Technical Field

[0001] This utility model relates to the field of LED display technology, specifically to a double-sided LED display cabinet. Background Technology

[0002] LED displays are composed of multiple LED panels and are used in shopping malls and squares. With the development of LED displays, nowadays displays are mostly single-sided, and the back cannot be displayed. This results in poor applicability, failure to meet the needs of applications, and difficulty in fully displaying information.

[0003] Therefore, in order to solve the above-mentioned technical problems, Chinese patent CN210324998U, a double-sided LED display device, points out that by rotatably setting LED display flip covers on both sides of the opening of the cabinet, a double-sided LED display can be formed, which can display on both the front and back of the cabinet, meet the diverse needs of users, make full use of display space, and save costs. Moreover, the double-sided display adopts a front and rear flip cover structure design, which can be used to inspect and maintain the display by opening the flip cover, making the display maintenance convenient and quick, and highly practical. The flip cover is supported and driven by a gas spring, making it easy and flexible to open and close, and convenient and quick to operate, saving time and effort. This patent can indeed solve the problems in the above-mentioned prior art, but there are still some defects. In this double-sided display, neither side can be rotated and adjusted, and its applicability is still insufficient. Even during maintenance, it can only be rotated upwards, which limits its working surface and is not conducive to maintenance work.

[0004] Therefore, in order to improve applicability, enable synchronous and asynchronous operation of the display screen on either side, achieve multi-sided adjustment, meet diverse customer needs, and facilitate subsequent maintenance, a double-sided LED display cabinet is proposed to solve the technical problems in the prior art.

The surface of the connecting pipe is in contact with the display screen mounting structure. Two sets of connecting plates are installed on the surface of the connecting pipe, and a shaft is connected between the two sets of connecting plates.

[0013] Compared with the prior art, the present invention provides a double-sided LED display cabinet, which has the following advantages: 1. This display cabinet comprises a drive structure, a rotating structure, a clamping structure, and a display mounting structure. The display mounting structure is clamped and fixed to the rotating structure by the clamping structure. The rotating structure rotates via the drive structure. When the display mounting structure needs to be rotated to the left, the clamping structure on the right side of the display mounting structure releases its clamping and fixing state from the rotating structure, and the drive structure on the left side of the inner support frame drives the rotating structure to rotate 0-90°. When the display mounting structure needs to be rotated to the right, the clamping structure on the left side of the display mounting structure releases its clamping and fixing state from the rotating structure, and the drive structure on the right side of the inner support frame drives the rotating structure to rotate. This allows the display mounting structure to rotate left or right on a single side, thereby improving the applicability of the cabinet and meeting customer needs.

[0014] 2. The display screen cabinet, through the aforementioned 0-90° rotation, provides a larger working space for staff during later maintenance and repair, thus facilitating subsequent maintenance and repair. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] Please see Figure 1-10 The present invention provides the following technical solution: a double-sided LED display cabinet, comprising a cabinet structure, which is composed of a side plate 1 and a top plate 2 connected together. A bottom support frame 3 is installed on the inner side of the top plate 2, and an inner support frame 10 is installed on the inner side of the bottom support frame 3. A bidirectional rotating structure is installed on the inner side of the bottom support frame 3. The bidirectional rotating structure includes a driving structure, a rotating structure, a clamping structure, and a display installation structure. The driving structure is installed on the side of the inner support frame 10, and one end is movably connected to the rotating structure. The display installation structure is installed on the rotating structure, and the clamping structure is installed on the inner side of the display installation structure. The bidirectional rotating structure is symmetrically distributed along the vertical longitudinal section of the side plate 1.

[0019] In this implementation plan, the specific working principle is as follows: the cabinet itself can display on both sides, such as... Figure 2 and 3As shown, based on this, in order to solve the applicability issues in the existing technology and meet the diverse needs of customers, improvements are made to the original cabinet. When the display structure on any side needs to be adjusted to the left or right within the range of 0-90°, assuming that the display structure on any side is adjusted to the left, the clamping structure on the right side of the display structure is released from its clamping and fixing state with the rotating structure. After release, the drive structure on the left side of the inner support frame 10 is activated, driving the rotating structure to rotate. At this time, the clamping structure on the left side of the display structure remains clamped to the corresponding rotating structure, so that the display structure can be rotated when the rotating structure rotates, thereby allowing for adjustment. If the display structure on any side rotates to the right, the opening and closing of the clamping structure is reversed. According to the above structural settings, the cabinet can display on both sides and can also be rotated to the left or right on either side, thereby improving the applicability of the cabinet and meeting the diverse needs of customers. Furthermore, the rotation of the display structure can provide a larger working surface for workers during later maintenance operations, thus facilitating maintenance work.

[0020] Based on the above, the specific details of the driving structure can be found in [reference needed]. Figure 3 and Figure 7 As can be seen, the driving structure includes a second mounting plate 11, a connecting piece 12, and an electric push rod 13. The second mounting plate 11 is bolted to the side of the inner support frame 10. The connecting piece 12 is welded to the outer end face of the second mounting plate 11 and arranged symmetrically. A shaft is fixedly installed between the two sets of connecting pieces 12 by bolts. An electric push rod 13 is movably installed on the surface of the shaft. The connection between the electric push rod 13 and the shaft is clamped by two sets of nuts. The telescopic end of the electric push rod 13 is movably connected to the rotating structure. Through the connection between the electric push rod 13 and the rotating structure, the rotating structure can be driven to rotate.

[0021] For details on how the rotating structure is driven to rotate by the drive structure, and how it drives the display screen mounting structure to rotate, please refer to [link to relevant documentation]. Figure 3 , Figure 5 , Figure 6-8 As can be seen, the rotating structure includes mounting plate 4, bearing seat 5, connecting flange 6, connecting pipe 7, elongated plate 8, connecting plate 9, and connecting shaft 14; mounting plate 4 is installed on the end face of the bottom support frame 3, and bearing seat 5 is installed on the surface of the bottom support frame 3. The inner ring of bearing seat 5 is connected to connecting flange 6, and connecting pipe 7 is connected to the surface of connecting flange 6. An opening is provided on the surface of connecting pipe 7, and elongated plate 8 is installed on the plane of the opening. Both the front and middle connecting pipe 7 and elongated plate 8 have openings on their surfaces, and the two sets of joints form a complete circular opening (see reference). Figure 10As can be seen, this facilitates the entry of the telescopic end of the electric push rod 20 in the clamping structure. A connecting shaft 14 is also installed in the middle of the surface of the connecting flange 6, and is enclosed within the connecting pipe 7. The surface of the connecting pipe 7 contacts the display screen mounting structure. Two sets of connecting plates 9 are installed on the surface of the connecting pipe 7, and a shaft connects the two sets of connecting plates 9. The surface of the shaft is movably connected to the telescopic end of the electric push rod 13. The telescopic end of the electric push rod 13 in the drive structure is connected to the connecting plate 9 located on the surface of the connecting pipe 7, thereby enabling the connecting pipe to rotate. The surface of the connecting shaft 14 located inside the connecting pipe 7 contacts the display screen structure and is clamped and fixed by the corresponding clamping structure. (See figure). Figure 9 As can be seen, through the above, the rotating structure can be driven to rotate by the electric push rod 13, and the display screen structure can rotate together.

[0022] Based on the above, the specific structure of the display screen can be found in [reference needed]. Figure 6 As can be seen, the display screen mounting structure includes a contact plate 15, an adjusting plate 16, a mounting plate 17, and an LED display screen 18. The LED display screen 18 is mounted on the outer surface of the mounting plate 17, the adjusting plate 16 is mounted on the inner side of the mounting plate 17, and the contact plates 15 are symmetrically mounted on the inner side of the adjusting plate 16. A clamping structure is mounted on the inner side of the adjusting plate 16. The contact plates 15 are in contact with the surface of the connecting shaft 14 and are clamped and fixed by the clamping structure. The contact plates 15 and the adjusting plate 16 are fixed by bolts. The initial state of the contact plates 15 is in contact with the surface of the connecting shaft 14 and is clamped and fixed by the clamping structure located on the rear end face of the adjusting plate 16. It should also be noted that the LED display screen 18 installed in the display screen structure is sealed for waterproofing and dustproofing at the main parts, and the method is consistent with the existing waterproofing and dustproofing sealing method. Therefore, it will not be described in detail.

[0023] Based on the above, the specific clamping structure can be found in [reference needed]. Figure 6 and Figure 9 As can be seen, the clamping structure includes a clamping box 19 and an electric push rod 20. The clamping box 19 is installed on the inner side of the adjusting plate 16, and a shaft is connected inside the clamping box 19. The electric push rod 20 is fixedly installed on the surface of the shaft. The outer side of the clamping box 19 has an opening. The telescopic end of the electric push rod 20 can pass through the opening and the circular opening on the surface of the connecting pipe 7 and the long strip plate 8 in sequence, and then contact the side of the electric push rod 20. Through the installation of the clamping box 19, the electric push rod 20 can be fixed inside the clamping box 19. An opening with the same cross-section as the electric push rod 20 is provided on the outer side of the clamping box 19, which facilitates the fixing of the electric push rod 20, allowing one end of the electric push rod 20 to extend out of the outside of the clamping box 19. Figure 6 and Figure 9As can be seen, when one side of the display screen structure is rotated, the corresponding clamping structure on the opposite side can be released from the clamping state of the electric push rod 20 and the contact plate 15.

[0024] To facilitate contact between the contact plate 15 and the connecting shaft 14 and prevent collisions, please refer to the following for details. Figure 9 As can be seen, the inner side of the contact plate 15 is provided with a V-shaped groove, and the tip is rounded.

[0025] To facilitate the passage of the electric actuator 20 through the circular opening located on the surface of the connecting tube 7 and the long strip plate 8, please refer to the following for details. Figure 10 It can be seen that the diameter of the circular opening on the surface of the connecting pipe 7 and the long strip plate 8 is larger than the diameter of the telescopic end of the electric push rod 20.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 make equivalent substitutions for some of the technical features.
