Description

Technical Field

[0001] The utility model relates to the technical field of explanation stands, in particular to a study and explanation stand. Background Art

[0002] Study tours are a new form of teaching that integrates learning with travel. They are off-campus activities that combine research-based learning with travel experiences. They focus on broadening students' horizons and cultivating their life skills, collective values, and practical abilities. Study tours involve organizing students off-campus through group travel or shared accommodations to broaden their horizons and enrich their knowledge. Teachers often carry a guide stand to display their lectures.

[0003] However, the explanation stands commonly used in study tours are generally large in size, and the structures of the explanation stands are mostly fixed, which makes them impossible to fold and collapse. Therefore, they usually take up a large space during transportation and are not convenient to carry around, which affects their flexibility of use. Utility Model Content

[0004] The purpose of the present utility model is to solve the shortcomings of the existing technology and to propose a study and explanation stand. Since the display stand can be rotated and adjusted, the user can easily adjust the display stand to the optimal viewing angle by sliding the adjustment block and adjusting the angle of the display stand. Secondly, the display stand can be expanded or contracted to facilitate carrying.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A study and explanation stand, comprising a bottom plate:

[0007] Two universal wheels are fixedly mounted on the lower end of the base plate, and two anti-slip bases are fixedly mounted on the side of the lower end of the base plate away from the universal wheels. The inner side of the base plate is rotatably connected to the display stand, and two adjustment mechanisms for adjusting the angle of the display stand are symmetrically arranged between the display stand and the base plate;

[0008] The side wall of the display rack is provided with a fixing mechanism for fixing the explanation items.

[0009] Preferably, the adjustment mechanism includes a rotating seat fixedly mounted on the upper end of the base plate, the interior of the rotating seat is rotatably connected to an adjustment frame, the other end of the adjustment frame is rotatably connected to an adjustment block, the side wall of the display rack is provided with a slide rail, and the adjustment block is located inside the slide rail.

[0010] Preferably, a locking bolt is threadedly connected to the adjusting block for fastening the adjusting block.

[0011] Preferably, the bottom plate is a right-angled U-shaped plate, and a hand-pull groove for pulling the bottom plate to move is provided at the upper end of the bottom plate.

[0012] Preferably, the fixing mechanism includes two fixing plates fixedly mounted on the side walls of the display rack, the side walls of the display rack are provided with a slide groove, a slide plate is slidably connected inside the slide groove, the slide plate and the slide groove are elastically connected by a spring, and a pressure plate is fixedly mounted on the side walls of the slide plate.

[0013] Preferably, a groove for limiting teaching supplies is formed on one side of the fixing plate opposite to the pressing plate.

[0014] The utility model has the following beneficial effects:

[0015] 1. By sliding the adjustment block and adjusting the angle of the display stand, users can easily adjust the display stand to the optimal viewing angle. Whether it is for the audience's visual comfort or to meet the needs of a specific exhibition space, precise positioning can be achieved. This flexibility greatly improves the display effect and makes information communication more efficient.

[0016] 2. The locking bolt is used to fix the adjustment block to ensure the stability of the display stand after the angle is adjusted. Once locked, the display stand can be firmly maintained in the set position, effectively preventing deviation or tipping due to external force, ensuring the safety and reliability of the display process;

[0017] 3. Through the combined design of the pressure plate and the spring, users can quickly and easily fix the display board on the fixed plate. This design not only improves the installation efficiency, but also makes the replacement of the display board easy and quick, providing great convenience for the exhibition.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0024] Reference Figure 1-Figure 3 A study and explanation stand includes a bottom plate 1, which is a right-angle U-shaped plate. The upper end of the bottom plate 1 is provided with a hand-pull groove 8 for pulling the bottom plate 1 to move:

[0025] Two universal wheels 2 are fixedly mounted on the lower end of the base plate 1, and two anti-slip bases 9 are fixedly mounted on the side of the lower end of the base plate 1 away from the universal wheels 2. The inner side of the base plate 1 is rotatably connected to the display rack 3. Two adjustment mechanisms for adjusting the angle of the display rack 3 are symmetrically arranged between the display rack 3 and the base plate 1. The adjustment mechanism includes a rotating seat 7 fixedly mounted on the upper end of the base plate 1, and the interior of the rotating seat 7 is rotatably connected to the adjustment rack 6. The other end of the adjustment rack 6 is rotatably connected to the adjustment block 11. The side wall of the display rack 3 is provided with a slide rail 12. The adjustment block 11 is located inside the slide rail 12. A locking bolt 10 is threadedly connected to the adjustment block 11 for fastening the adjustment block 11.

[0026] The side wall of the display rack 3 is provided with a fixing mechanism for fixing the explanation items, and the fixing mechanism includes two fixing plates 4 fixedly installed on the side wall of the display rack 3. The side wall of the display rack 3 is provided with a slide groove, and a slide plate 13 is slidably connected inside the slide groove. The slide plate 13 is elastically connected to the slide groove by a spring 14. A pressure plate 5 is fixedly installed on the side wall of the slide plate 13, and a groove for limiting the explanation items is provided on the side opposite to the fixing plate 4 and the pressure plate 5.

[0027] Working principle:

[0028] When in use, after moving the base plate 1 to a predetermined location, the anti-slip base 9 is lowered and in contact with the ground, and then the locking bolt 10 is loosened to release the restriction on the adjustment block 11. The adjustment block 11 slides along the slide rail 12. At this time, the display stand 3 can be rotated. When the angle of the display stand 3 is adjusted, the adjustment block 11 can be locked and fixed by the locking bolt 10 to achieve the purpose of fixing the display stand 3.

[0029] Put the display board into the groove on the fixing plate 4, then pull the pressing plate 5 to put the spring 14 in a stretched state, and align the groove of the pressing plate 5 with the top surface of the display board to complete the fixation of the display board, which is convenient for explanation and use.
