Description

Technical Field

[0001] The utility model relates to the technical field of conference screens, in particular to a portable conference screen. Background Art

[0002] In current conference rooms, audio-visual teaching rooms, etc., it is no longer just a podium, a chair, and a microphone as before. Instead, there are various advanced multimedia conference and teaching devices. Such as: projectors, DVD players, video recorders, video display platforms, multimedia computers, electric screens. Some large conference rooms are also equipped with simultaneous interpretation systems, electronic voting systems, large-screen projections, multi-screen switching systems, etc. In addition to some fixed conference venues, sometimes due to some exhibition or demonstration needs, a temporary conference system also needs to be set up to meet the conference requirements. Among them, conference screens are often used. However, most conventional conference screen systems are fixedly installed and not convenient to carry and use.

[0003] In order to meet the needs of temporarily setting up a venue, the utility model with the publication number CN212723817U discloses a portable conference screen, which includes a conference screen and a conference screen bracket. The conference screen is detachably connected to the conference screen bracket. The conference screen bracket includes a vertically arranged bracket and a chassis that are detachably connected. A locking device is provided on the upper side of the chassis for locking the connection between the vertically arranged bracket and the chassis. A sliding wheel is provided on the lower side of the chassis. By providing the conference screen bracket, it is convenient to set up the conference screen in a temporary conference venue. By providing a detachably connected conference screen and conference screen bracket, it is convenient to disassemble and carry. The conference screen bracket is set as a detachably connected chassis and vertically arranged bracket, which further improves the convenience. A pulley device is provided on the lower side of the chassis to facilitate moving the conference screen and displaying the conference content from a suitable angle.

[0004] Although the bracket in the above solution can be disassembled into a chassis and a vertically arranged bracket, the chassis, the vertically arranged bracket, and the conference screen are independent of each other. During the handling process, they need to be transferred separately, but they need to be stored together during transportation. Otherwise, it may occur that parts cannot be found completely or parts are lost, affecting the assembly and use of the conference screen. Summary of the Utility Model

[0051] The front-to-back central axes of the top connecting seat 202 and the bottom connecting seat 103 coincide.

[0052] A plug block is provided at the top of the telescopic rod 3, a top connecting seat 202 is provided on the rear housing 204, and a slot corresponding to the plug block is provided at the bottom of the top connecting seat 202.

[0053] The plug block can be a quadrangular prism, and the slot is a quadrangular prism groove. During use, the quadrangular prism is inserted into the quadrangular prism groove to connect the telescopic rod 3 and the display screen 2 together.

[0054] A tightening bolt 212 is provided on the top connecting seat 202, and the end of the tightening bolt 212 abuts against the plug block.

[0055] The tightening bolt 212 is arranged along the radial direction of the telescopic rod 3, and the tightening bolt 212 is threadedly connected to the top connecting seat 202. After the plug block is inserted into the slot, the tightening bolt 212 is tightened to prevent the plug block from automatically separating from the slot.

[0056] There are two telescopic rods 3. A limiting ring is provided on the telescopic rod 3, and a support rod 4 is arranged between the two telescopic rods 3. The support rod 4 is lapped with the limiting ring.

[0057] The two telescopic rods 3 provide more stable support. The inner diameter of the limit ring is the same as the outer diameter of the telescopic rod 3, and it is fixedly sleeved on the telescopic rod 3 to limit the height of the support rod 4 and prevent the support rod 4 from slipping.

[0058] The support rod 4 is lapped on the limit ring to further improve the stability of the support of the two telescopic rods 3.

[0059] The support rod 4 includes two rod bodies 401. Second studs 403 and second screw holes screwed with the second studs 403 are respectively arranged on the end faces of the two rod bodies 401 close to each other. Semi-circular rings 402 lapped with the limit ring are arranged on the end faces of the two rod bodies 401 far from each other.

[0060] The inner diameter of the semi-circular ring 402 is the same as the outer diameter of the telescopic rod 3. When carrying the device, turn the rod body 401 to separate the second stud 403 from the second screw hole, and store the two rod bodies 401 in the support rod groove 506. When assembling the device, screw the two rod bodies 401 together and lap them on the limit ring through the semi-circular rings 402.

[0061] Working principle: When in use, open the carrying case 1, take out the display screen 2, telescopic rods 3, and support rods 4, then close the case lid 101, and place the carrying case 1 at the display position at the site of the temporary meeting place;

[0062] Then screw the first stud into the first screw hole 104 to screw the telescopic rod 3 onto the case lid 101. After adjusting the telescopic rod 3 to the appropriate height, lift the display screen 2, insert the insertion block into the slot, and tighten the fastening bolt 212;

[0063] Finally, screw the two rod bodies 401 together and then lap them on the limit ring.

[0064] When it needs to be carried, remove the display screen 2, telescopic rods 3, and support rods 4 and store them in the carrying case 1.
