Description

Technical Field

[0001] The utility model relates to the technical field of welcome signboards, in particular to a welcome signboard with a holographic electronic screen. Background Art

[0002] A typical welcome sign is a simple device used to display various information such as welcome messages, notices, etc.

[0003] Existing welcome signs display content by printing or handwriting on a flat drawing. Every time the content is updated, the drawing must be removed and replaced with a new one, which is very troublesome to use. In addition, they also have common shortcomings such as dull appearance, lack of vividness, waste of paper, and increased time and workload for changing the board.

[0004] For example, the LED welcome board disclosed in announcement number CN202093778U embeds an LED display screen into the welcome board. The content edited in the computer can be directly and conveniently sent to the LED indicator screen, which solves the paper loss caused by the need to print or copy traditional welcome boards and the manual energy loss caused by tedious layout changes. The LED display screen is connected to an RS-232 serial port data cable and a wireless data transceiver module, which is more convenient and quick.

[0005] However, when the LED display screen is damaged during use, it is inconvenient to disassemble and replace the LED display screen, which is inconvenient to use.

[0006] For this reason, we urgently need to provide a kind of welcome sign with holographic electronic screen. Utility Model Content

The connecting plate is slidably connected inside the upper and lower mounting plates, and is slidably connected to the upper and lower mounting plates through the connecting plate, thereby facilitating the installation of the holographic electronic screen on the mounting plate.

[0013] Preferably, the upper and lower ends of the protrusion are provided with card slots, and the diameter of the card slots is equal to the diameter of the card rod. The card rod is engaged with the card slots of the protrusion, thereby facilitating the fixing of the connecting plate between the upper and lower mounting plates.

[0014] Preferably, the fixing block is provided with an internal thread, the threaded rod is threadedly connected to the inside of the fixing block, and the bottom of the brake block is provided with anti-slip grooves.

[0027] Example 1: A welcome sign with a holographic electronic screen includes a base plate 1, a support column 2, a connecting plate 3 and a holographic electronic screen 4. The support column 2 is fixedly installed on the top of the base plate 1, the connecting plate 3 is arranged on the left side of the upper end of the support column 2, and the holographic electronic screen 4 is installed on the front of the connecting plate 3. An installation device is provided above the base plate 1, and the installation device includes a fixed unit and a movable unit.

[0028] The fixed unit is arranged on the left side of the upper end of the base plate 1 , and the movable unit is arranged on the bottom of the base plate 1 .

[0029] The fixing unit includes a mounting plate 501, a protrusion 502, a spring 503, a disc 504, a clamping rod 505 and a pull rod 506. The mounting plate 501 is fixedly mounted on the upper and lower ends of the outer side of the support column 2. A sliding groove is provided on the adjacent side of the upper and lower mounting plates 501, and the width of the sliding groove is equal to the width of the connecting plate 3. The connecting plate 3 is slidably connected to the upper and lower mounting plates 501. The holographic electronic screen 4 is easily installed on the mounting plate 501 through the sliding connection with the upper and lower mounting plates 501. The protrusion 502 is fixedly mounted on the right side of the connecting plate 3. A clamping groove is provided inside the upper and lower ends of the protrusion 502, and the diameter of the clamping groove is equal to the diameter of the clamping rod 5 05 are equal in diameter, and the clamping rod 505 is clamped with the clamping groove opened by the protrusion 502, so as to facilitate fixing the connecting plate 3 between the upper and lower mounting plates 501, one end of the spring 503 is fixedly installed on the adjacent side of the upper and lower mounting plates 501, and the disk 504 is fixedly installed on the other end of the spring 503, the clamping rod 505 is fixedly installed on the end of the disk 504 away from the spring 503, and the pull rod 506 is fixedly installed on the side of the disk 504 away from the clamping rod 505 and extends to the outside of the mounting plate 501. Pulling the upper and lower pull rods 506 outward drives the clamping rod 505 to disengage from the clamping groove opened by the protrusion 502, thereby disassembling the holographic electronic screen 4.

[0030] Example 2: Based on Example 1: the mobile unit includes a universal wheel 601, a fixed block 602, a threaded rod 603 and a brake block 604.

The protective shell 7 protects the holographic electronic screen 4 to prevent the holographic electronic screen 4 from being damaged by collision.

[0033] When in use, push the support column 2 to cooperate with the universal wheel 601 to move the device to the desired position, then rotate the threaded rod 603 to threadably connect with the fixing block 602 to drive the brake block 604 to move down and abut against the ground, so as to facilitate the fixation of the device, and then the welcome information is displayed on the holographic electronic screen 4. When the holographic electronic screen 4 is damaged and needs to be replaced, pull the upper and lower pull rods 506 outward to drive the clamping rod 505 out of the clamping slot provided by the protrusion 502, and then pull the connecting plate 3 to the left until the holographic electronic screen 4 is separated from the mounting plate 5 01, then insert the connecting plate 3 on the back of the new holographic electronic screen 4 into the sliding groove provided on the mounting plate 501, and then push the connecting plate 3 to move to the right along the mounting plate 501. During the movement, the arc surface of the protrusion 502 contacts the card rod 505, so that the card rod 505 moves along the arc surface while squeezing the spring 503. When the card rod 505 and the card slot are on the same straight line, the spring 503 resets and pushes the card rod 505 into the card slot, thereby realizing the installation and fixation of the connecting plate 3 and the holographic electronic screen 4, which is convenient for assembly and disassembly and efficient.
