Description

Electronic display screen of many screen combinations

Technical Field

The invention belongs to the technical field of electronic display screens, and particularly relates to a multi-screen combined electronic display screen.

Background

The electronic display screen can display variable numbers, characters and graphic images; the LED lamp can be used in indoor environment and outdoor environment, and has the advantages of being incomparable to projectors, television walls and liquid crystal display screens. Electronic displays can generally be divided into two interpretations

One explanation is: the electronic display screen is formed by uniformly arranging tens of thousands to hundreds of thousands of semiconductor light-emitting diode pixel points. Different materials can be used for manufacturing LED pixel points with different colors. The most widely used at present are red, green and yellow. While the development of blue and pure green LEDs has reached a practical stage.

Another explanation is that: the electronic display screen is a screen body formed by a plurality of combinable and spliced display units (unit display panels or unit display box bodies), and a set of proper controller (a main control panel or a control system) is added to control the display of the electronic display screen. Therefore, the display panels (or unit boxes) with various specifications can be matched with controllers with different control technologies to form a plurality of LED display screens so as to meet the requirements of different environments and different display requirements.

At present, for the assembling operation of the electronic display screen, the assembled components usually include a unit display panel, an outer frame, a magnet block with a stud, a keel, a power supply, and the like, and the actual assembling mode is as follows: firstly, assembling and molding the outer frame, then uniformly laying the unit display panels in the range surrounded by the outer frame, fixedly connecting the magnet blocks with the studs to the back of the unit display panels through threads, then installing the keels in the outer frame at equal intervals, wherein the keels can be magnetically connected with the magnet blocks with the studs, therefore, after the keels and the outer frame are fixed, the unit display panels are magnetically connected to the keels through the magnet blocks with the studs, finally, adjusting the unit display panels to be in an orderly state, and installing a power supply.

As can be seen from the above description of the installation manner of the electronic display screen in the prior art, the main technical problems exist in that: all realize being connected fixedly of unit display panel and outline through the mode of magnetism among the prior art, and owing to be connected to the fossil fragments back on with unit display panel magnetism, because a plurality of unit display panels at this moment still are in uneven state, consequently still need carry out meticulous regulation to the position of unit display panel, this needs the connection face of magnet piece and fossil fragments to be the plane, otherwise the position of the unit display panel after the magnetism is connected can't carry out meticulous regulation, just so also lead to the connected mode of unit display panel and fossil fragments firm problem inadequately.

As shown in fig. 3, the other end of the round rod 211 is fixedly connected with the positioning plate 213, the opening position of the square hole 1121 near the outer side surface of the fixed frame 112 is provided with a positioning slot 1122, and the thickness of the positioning plate 213 is the same as the depth of the positioning slot 1122, that is, the positioning plate 213 can be completely accommodated in the positioning slot 1122; in the state shown in fig. 1, the positioning plate 213 is completely received in the positioning groove 1122 provided at the top of the topmost fixing frame 112.

The working principle is as follows: when the electronic screen 111 is actually installed, the spring plate 1131 and the clamping plate 1133 only need to be aligned, and then the electronic screen 111 is directly pushed up, when the top of the quadrangular frustum 1134 contacts with one edge position of the bottom of the clamping plate 1133, because the top of the quadrangular frustum 1134 is an inclined surface, the vertical upward acting force of the quadrangular frustum 1134 can be decomposed into a continuous upward acting force and a horizontal acting force, the horizontal acting force can push the quadrangular frustum 1134 to gradually move away from the clamping plate 1133, at this time, the spring plate 1131 is in a bent state, and then after the spring plate 1131 is bent to a certain degree, the quadrangular frustum 1134 can slide upward along the side surface of the clamping plate 1133, until the quadrangular frustum 1134 moves to one side of the clamping inclined surface 1136, the elastic force generated after the spring plate 1131 is bent can push the quadrangular frustum 1134 to return to the original position, the inclined surface at the bottom of the quadrangular frustum 1134 is pushed to be attached to the inclined surface 1136, and the clamping connection of the electronic screen 112 is completed;

when the electronic screen 111 needs to be detached, firstly, in a normal state, the pressing plate 1153 is in a vertically downward state and is located inside the buffer groove 1135, and the side surface of the pressing plate 1153 is attached to the side surface of the quadrangular frustum pyramid block 1134, in such a state, due to the extrusion effect of the pressing plate 1153 on the quadrangular frustum pyramid block 1134, the inclined surface at the bottom of the quadrangular frustum pyramid block 1134 and the clamping inclined surface 1136 can be kept in a stable attached state, so that the situation that the inclined surface at the bottom of the quadrangular frustum pyramid block 1134 and the clamping inclined surface 1136 are detached from the attached state in an unexpected situation can be avoided, and the attachment stability and reliability of the inclined surface at the bottom of the quadrangular frustum pyramid block 1134 and the clamping inclined surface 1136 are also obviously enhanced; when the joint state between the inclined plane at the bottom of the quadrangular frustum pyramid 1134 and the clamping inclined plane 1136 needs to be released, so as to achieve the purpose of detaching the electronic screen 111, the rotating shaft 1152 is directly rotated, the pressing plate 1153 is gradually changed from downward to upward, the originally upward pressing plate 1154 is gradually changed to downward, in the process, on one hand, the pressing blocking effect of the pressing plate 1153 on the quadrangular frustum pyramid 1134 is eliminated, and on the other hand, in the process that the pressing plate 1154 is gradually changed to downward, the hemispherical surface of the second hemispherical head 1155 is firstly contacted with the inclined plane at the side part of the quadrangular frustum pyramid 1134, and then the quadrangular frustum pyramid 1134 is pushed to gradually move leftward until the joint between the inclined plane at the bottom of the quadrangular frustum pyramid 1134 and the clamping inclined plane 1136 is released, at this time, the clamping relationship between the quadrangular frustum pyramid 1134 and the clamping plate 1133 is released, and then the electronic screen 111 can be rapidly detached; during the process of rotating the rotating shaft 1152 by the user, a certain turning force exists in the rotating shaft 1152 due to the torsion spring 1158, and when the user does not apply torsion to the rotating shaft 1152 any more, the rotating shaft 1152 is rapidly reset under the action of the torsion spring 1158; when the supporting mechanism 210 is installed, the supporting mechanism 210 can be held tightly, so that the two right-angle plates 212 can lean against the round rod 211 as much as possible, at this time, the diameter of the whole supporting mechanism 210 is reduced, and in this state, a user can more conveniently and labor-saving penetrate the supporting mechanism 210 through the square hole 1121.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
