Detailed Implementation

[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] like Figures 1-5 As shown, the present invention provides a fresh food display screen, comprising a fresh food display screen body consisting of several display screen units 100 horizontally spliced ​​together to display fresh food product information. The fresh food display screen body is provided with a hanging bracket 200 for fixing to the ceiling of a supermarket. Each display screen unit 100 is provided with a heat-conducting back plate 1 on its back. A heat sink 2 is detachably provided on the heat-conducting back plate 1. Connecting brackets 3 for stable support are symmetrically arranged on the upper and lower sides between two adjacent display screen units 100.

[0025] Several circular grooves 4 are evenly distributed on the heat-conducting back plate 1;

[0026] The fixing mechanism 5 is correspondingly provided on the radiator 2 and the connecting bracket 3, and is used to fit into the interior of the circular groove 4 and rotate to fix it.

[0027] In specific implementation, the heat-conducting back plate 1 is screwed and installed on the back of the display unit 100, and the circular groove 4 is uniformly machined on the heat-conducting back plate 1. The fitting insertion of the fixing mechanism 5 installed at the corner of the heat sink 2 inside the circular groove 4 makes it possible to detachably assemble the heat sink 2 on the back of the heat-conducting back plate 1. The combined heat-conducting back plate 1 and heat sink 2 can effectively dissipate heat during long-term high-load operation and avoid screen overheating.

[0028] Furthermore, by using the adaptable insertion of the fixing mechanism 5 distributed on the connecting frame 3 within the circular groove 4, two adjacent spliced ​​display screen units 100 can be stably connected, which can firmly support two or more display screen units 100, preventing the display screen units 100 from loosening or shifting. With the cooperation of the circular groove 4 and the fixing mechanism 5, the splicing operation is made convenient, and the heat sink 2 can be easily installed and removed.

[0029] It should be noted that the heat sink 2 is often used in the prior art fan heat sink, liquid cooling heat dissipation system, thermoelectric refrigeration and phase change material heat dissipation.

[0030] It should be noted that the fresh screen body can upload the content to be displayed in the background management system, such as promotion advertisement, commodity recommendation, video, etc., and set the playing content according to different regions and time periods, support timing playing and cycle playing; employees can also bind the commodity information with the fresh screen body, and the fresh screen body can display the commodity information after binding.

[0031] In an embodiment, the fixing mechanism 5 includes a rotating block 51 rotatably arranged at the corner end of the heat sink 2 and the connecting frame 3, and a support ring 52 arranged on one end of the heat sink 2. An opening is arranged on one side of the support ring 52 corresponding to the heat sink 1, and a movable round plate 53 is rotatably arranged in the opening. In this way, by using turning machining to groove and rotate the rotating block 51 on the heat sink 2 and the connecting frame 3, and by turning machining to groove and rotate the movable round plate 53 on the support ring 52, the fixing mechanism 5 is combined and inserted into the circular embedding groove 4, and the structure is simple.

[0032] In an embodiment, a cylindrical protrusion 41 is arranged on the inner side wall of the circular embedding groove 4 along the radial direction of the circular embedding groove 4, one side of the movable round plate 53 is provided with a through groove 54 for the cylindrical protrusion 41 to pass through, and the circumferential surface of the support ring 52 is provided with an arc groove 55 for the rotation of the cylindrical protrusion 41. In this way, by welding the cylindrical protrusion 41 on the groove side wall of the circular embedding groove 4 along the radial direction of the circular embedding groove 4, and by turning machining the through groove 54 on the movable round plate 53 corresponding to the size specification of the cylindrical protrusion 41, when the fixing mechanism 5 is inserted into the circular embedding groove 4, the cylindrical protrusion 41 passes through the through groove 54;

[0033] The arc groove 55 is also turned machined on the circumferential surface of the support ring 52, so that the cylindrical protrusion 41 enters the arc groove 55 through the through groove 54.

[0034] In an embodiment, the inner side of the arc groove 55 is provided with a support column connecting the movable round plate 53 and the rotating block 51. In this way, by welding the support column between the inner side of the arc groove 55 and the movable round plate 53 and the rotating block 51, rotating the rotating block 51 can drive the movable round plate 53 to rotate, so that the corresponding through groove 54 on the movable round plate 53 deviates from the installation position of the cylindrical protrusion 41, and the cylindrical protrusion 41 is limited by the support column in the arc groove 55, thereby maintaining the stability of the fixing mechanism 5 in the corresponding circular embedding groove 4.

[0035] In an embodiment, the display screen unit 100 is provided with a contact 101 on both sides;

[0036] The contact 101 is used to keep the display effect consistent after the two adjacent display screen units 100 are fixed. Through the contacts 101 installed on both sides of the display screen unit 100, the physical connection position can be determined after the display screen units 100 are fixed and spliced, and the consistency of the screen backlight and color is related. At the contact 101 of the display screen unit 100, the display effect is kept consistent, color difference is avoided, and brightness consistency is maintained.

[0037] In an embodiment, the outer side of the arc groove 55 is provided with a through port, and the inner groove side wall of the circular embedding groove 4 is further provided with an arc plate which is adapted to be inserted into the through port. Through the through port left on the outer side of the arc groove 55 and the arc plate welded on the position of the corresponding cylindrical protrusion 41 of the inner groove side wall of the circular embedding groove 4, after the fixing mechanism 5 is inserted into the circular embedding groove 4, the adaptability of the through port and the arc plate is inserted, which can limit the movement of the supporting ring 52.

[0038] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

[0039] It should be noted that if the present application involves directional indications such as up, down, left, right, front, back, etc., the directional indications are only used to explain the relative position relationship, movement condition, etc. between the components in a certain posture, and if the certain posture changes, the directional indications will also change accordingly.
