Description

Technical Field

[0001] The utility model relates to a quick power-taking structure for a display device and the display device. Background Art

[0002] Display devices used for merchandise display typically consist of an electrically powered display panel and display structures such as light boxes, display screens, illuminated shoe trays, and illuminated logos that require electrical connection. Conventional display devices lack quick-connect power connections, so the display panel and display structure typically rely on fixed connections. In practice, the display structure often needs to be moved, making fixed connections extremely inconvenient.

[0003] The Chinese invention patent application number is 201910414636.3, and the name is a patent for a quick power connection structure and a display system using the power connection structure. It discloses that the quick power connection structure includes a charged base assembly and a power extraction assembly. The charged base assembly is provided with an insertion hole, and two first conductive components are provided in the insertion hole; the power extraction assembly is plugged into the insertion hole, and it is provided with two second conductive components. When the power extraction assembly is plugged into the insertion hole, the first conductive component and the second conductive component are in contact, thereby achieving quick power connection. However, since the clearance holes of the power extraction shell are provided on its left and right sides, the part of the second conductive component extending into the insertion hole is located on the left and right outer sides of the power extraction shell, resulting in a larger size of the power extraction assembly, and the insertion hole of the charged base also needs to be set larger to accommodate the protruding part of the second conductive component. That is, the quick power connection structure is relatively complex, large in size, and not neat enough. Utility Model Content

[0004] The present invention provides a quick power supply structure and a display device for a display device, which overcomes the shortcomings of the background technology. One of the technical solutions adopted by the present invention to solve the technical problem is:

[0005] A quick power supply structure for a display device, comprising:

[0006] The base includes a base body, an end cover, and a conductive sheet. The base body is provided with a socket extending from front to back. The end cover is connected to the rear end of the base body and is provided with a conductive sheet slot. The conductive sheet slot has a first opening and a second opening at each end. The first opening of the conductive sheet slot is located on the top surface of the end cover and faces the socket, and the second opening is located on the side of the end cover. The head end of the conductive sheet is inserted into the conductive sheet slot with its front side corresponding to the first opening. The tail end of the conductive sheet extends out of the second opening and is connected to the power cord.

[0007] The power collection component includes a power collection shell, a current needle and a power collection female plug. The current needle is installed in the power collection shell along the length direction of the power collection shell and its end extends out of the bottom end surface of the power collection shell. The current needle head end extends out of the power collection shell and is connected to the power collection female plug; the power collection shell and the socket are detachably plugged in and matched. When the power collection shell and the socket are plugged in and matched, the end of the current needle passes through the first opening of the conductive plate slot and contacts the conductive plate.

[0008] In a preferred embodiment, the power taking housing is provided with a first clamping portion, and the base body is provided with a second clamping portion. When the power taking housing is plugged into the socket, the first clamping portion and the second clamping portion are clamped into each other.

[0009] In a preferred embodiment, a recessed slot is provided on the outer periphery of the power taking housing, the first clamping portion is a first elastic clamping arm fixed in the recessed slot, and the second clamping portion is a first clamping hole connected to the socket.

[0010] In a preferred embodiment, the base body is provided with an external thread on its outer periphery and a locking nut is further provided, and the locking nut is threadedly connected to the outer periphery of the base body.

[0011] In a preferred embodiment, a transversely extending limiting ring is provided on the top surface of the base body.

[0012] In a preferred embodiment: the rapid power-taking structure further includes a power-taking component, and the power-taking component is provided with a male socket that can be plugged into and matched with a female power-taking plug.

[0013] In a preferred embodiment, the end cover is provided with a second elastic clamping arm, and the bottom end of the base body is provided with a second clamping hole, and the second elastic clamping arm is clamped at the second clamping hole to connect the end cover to the base body.

[0014] The second technical solution adopted by the present invention to solve its technical problem is:

[0015] A display device, which uses the quick power extraction structure for display devices, includes a display panel, a charged display piece and several of the quick power extraction structures. The display panel is provided with several assembly holes, the bases are installed in the assembly holes one by one, and the power extraction components are arranged on the charged display piece.

[0016] In a preferred embodiment: the outer periphery of the base body is provided with an external thread, the top surface of the base body is provided with a laterally extending limit ring, the limit ring is against the outer end surface of the assembly hole, the base body is sleeved in the assembly hole, and a locking nut is further provided, the locking nut is threaded on the outer periphery of the base body and pressed against the inner end surface of the assembly hole.

[0017] In a preferred embodiment, the electrified display element includes a light box, a display screen, a luminous shoe tray, a luminous LOGO board and a luminous display board.

[0018] Compared with the background technology, this technical solution has the following advantages:

[0019] 1. Because the conductive sheet is located at the bottom end of the socket and the current needle is located at the bottom end of the power supply housing, when the power supply assembly is inserted into the socket, the conductive sheet contacts the current needle, allowing the current needle to conduct electricity. Because both the conductive sheet and the current needle are located at the end surface, they do not occupy lateral space, allowing the base and power supply assembly to be designed to be more compact, beautiful, and neat.

[0020] 2. The engagement between the first and second engaging portions can increase the connection strength between the base and the power extraction component, preventing the power extraction component from falling out of the socket.

[0021] 3. The setting of the locking nut can connect and fix the base and the display panel.

[0022] 4. The setting of the limiting ring, which is used in conjunction with the locking nut, can firmly fix the base body in the assembly hole. BRIEF DESCRIPTION OF THE DRAWINGS
