Description

Technical Field

[0001] The utility model relates to the technical field of demonstration boards, in particular to a rotationally adjustable demonstration board. Background Art

[0002] Demonstration boards are generally used as writing boards for demonstration or explanation, such as football display boards. There are two types of football tactical boards in general use: one is a large stand-type tactical board, and the other is a small handheld tactical board. Both are printed with football field maps on magnetic boards, equipped with magnetic chess pieces, oil-based pens and erasers; the main difference is the printed football field maps are different. The stand-type generally only prints a complete field map, and the handheld type generally has one or more half-field maps in addition to a complete map.

[0003] Patent CN208212470U proposes a football tactical board, which replaces athletes by attaching magnetic patches on a relatively immovable magnetic glass whiteboard, simulates athletes by moving the football field plane model formed by LED light strips left and right, and realizes the relative movement of the magnetic patches by moving the back panel left and right at the order of the LED light strips on the football field plane model formed by turning on the LED light strips.

[0004] The above scheme has the following problems in conventional use: first, after the tactical strategy of drawing with the oil pen, it needs to be wiped manually with a blackboard eraser, which is inefficient; in addition, the existing common large-scale demonstration boards are usually usable on both sides and can be replaced by flipping, but there is a lack of certain locking measures after the flipping is completed, which makes the demonstration board easy to rotate during drawing. Utility Model Content

The utility model has a novel structure. The inclination angle of the vertical frame and the board body can be adjusted by the screw on the bottom plate to facilitate better demonstration and use of the board body. The board body can be quickly wiped by the wiping plate on the top of the vertical frame, and the magnetic chess pieces used in football tactics can be collected and sorted for easy redrawing. At the same time, the board body can be locked with a pin to prevent the board body from rotating during use.

[0006] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a rotating and adjustable demonstration board, comprising a base plate, two groups of vertical plates are symmetrically arranged on the top of the base plate, a board body is rotatably installed between the two groups of vertical plates through bearings, a cleaning assembly is provided on the top of the vertical plate, and the cleaning assembly comprises a wiping plate, a wiping pad is provided on the inner side of the wiping plate and is in sliding contact with the board body, the outer side of the wiping plate is a box body that slides along both sides of the board body, a slide groove is provided on the surface of the vertical plate, and a slider is slidably connected inside the slide groove, both sides of the wiping plate box body are fixedly connected to the slider, a telescopic rod is symmetrically rotatably installed on the rear end of the base plate through a rotating shaft, and the extended end of the telescopic rod is rotatably connected to the bottom of the back side of the vertical plate through a rotating shaft.

[0007] Furthermore, a plug rod is slidably inserted at the bottom of the vertical plate, and the bottom of the plug rod is rotatably mounted on the surface of the bottom plate through a rotating shaft.

[0008] Furthermore, a locking bolt is engaged and inserted on the outer side of the bottom of the vertical plate, and the inner end of the locking bolt can be pressed and contacted with the insertion rod.

[0009] Furthermore, a moving groove is provided on the middle surface of the bottom plate, and a moving plate is slidably connected inside the moving groove. A screw is rotatably installed in the moving groove through a bearing, and the moving plate is meshingly sleeved on the surface of the screw.

[0010] Furthermore, a connecting rod is rotatably mounted on the top of the movable plate via a rotating shaft, and the other end of the connecting rod is rotatably connected to a transverse plate via a rotating shaft, and both ends of the transverse plate are slidably sleeved on the surface of the inserted rod.

[0011] Furthermore, the cleaning assembly also includes a third ear plate, the third ear plate is fixed on the outer surface of the sliding block, and a latch is slidably inserted inside the third ear plate.

[0012] Furthermore, second ear plates are fixed on both sides of the front and back sides of the plate body at positions corresponding to the third ear plates, and a first ear plate is fixed on the surface of the vertical plate at positions corresponding to the third ear plates, and the latch can be slidably inserted into the second ear plate or the first ear plate.

[0015] 1. The utility model extends the vertical plate through the insertion rod and locks the length through the locking bolt, so that the height of the plate body can be adjusted as needed.

[0016] 2. The utility model drives the movable plate to slide along the movable groove by rotating the screw rod, pulls the horizontal plate to slide along the surface of the plug rod through the connecting rod, and then cooperates with the rotation of the telescopic rods on both sides of the bottom plate to adjust the inclination angle of the vertical frame and the plate body for better demonstration.

[0017] 3. When the latch is located in the middle position and is not plugged into the first ear plate and the second ear plate, the spring force drives the slider along the slide groove and the slide rod, and the wiping plate quickly descends along the surface of the board body to wipe the oily pen writing on the surface of the board body, and pushes the magnetic chess pieces on the surface to the bottom of the board body, so that they can be directly taken out when used next time. When the latch is plugged into the first ear plate and the third ear plate, the wiping plate is limited by the vertical plate and cannot move vertically, and the board body can be flipped over. When the latch is located in the second ear plate and the third ear plate, the board body is vertically limited by the slider and cannot rotate, thereby maintaining the stability of the board body when the front side is used.

[0018] 4. Compared with the prior art, the utility model can adjust the inclination angle of the vertical frame and the board body through the screw on the bottom plate, so as to better demonstrate and use the board body. The board body can be quickly wiped through the wiping plate on the top of the vertical frame, and the magnetic chess pieces used in football tactics can be collected and sorted, which is convenient for redrawing. At the same time, the board body can be locked with a latch to prevent the board body from rotating during use. BRIEF DESCRIPTION OF THE DRAWINGS
