DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The logistics distribution teaching demonstration device is a teaching tool used to simulate and demonstrate the logistics distribution process. This device usually uses a display screen to show students the various links, processes and technologies involved in logistics distribution.

[0025] Example 1

[0026] In existing devices, the display screen is exposed to the outside for a long time when not in use. The exposed display screen is easily affected by environmental factors such as dust and pollutants, resulting in dust and stains on the screen surface, affecting the display effect and even damaging the screen. In addition, the display screen will be affected by humidity when exposed to the outside for a long time, especially in humid conditions, which will cause aging and damage of electronic components, thereby reducing the life of the display screen. Please refer to Figure 1-Figure 4 The embodiment provides a logistics distribution teaching demonstration device, including a screen mounting box 1 and a mounting frame 2 fixed on the rear side of the screen mounting box 1, the internal sliding sleeve of the screen mounting box 1 is provided with a screen placing plate 3, the inner bottom of the screen mounting box 1 is provided with a storage mechanism 5 for driving the screen placing plate 3 to move downward to place the display screen into the screen mounting box 1, and a screen cleaning mechanism 7 for cleaning dust on the surface of the screen mounting box 1 under the synchronous drive of the storage mechanism 5.

[0027] refer to Figure 2-Figure 3As shown, when the display screen is not in use, it is exposed to the outside and is easily affected by environmental factors such as dust and pollutants, resulting in dust and stains on the screen surface, affecting the display effect and even damaging the screen. In addition, long-term exposure of the display screen to the outside will cause the display screen to be affected by humidity, especially under humid conditions, which will cause aging and damage to electronic components, thereby reducing the life of the display screen. In order to extend the life of the display screen, the following settings are made: the storage mechanism 5 includes a motor 51 fixed to the inside of the screen mounting box 1, and the output end of the motor 51 is fixedly connected to a bidirectional threaded screw 52, ​​and the outer wall of the bidirectional threaded screw 52 is threadedly connected to two moving blocks 53, and the bottom of the two moving blocks 53 are fixedly connected to a slider, and the inner bottom wall of the screen mounting box 1 is provided with a slide groove, and the slider slides left and right along the length direction of the slide groove to limit the displacement path of the two moving blocks 53. Function: the tops of the two shift blocks 53 are movably connected with two force plates 54, and one end of the two force plates 54 away from the two shift blocks 53 is movably connected to the bottom of the screen plate 3. The top of the display screen is fixedly connected with a top cover 55 that is tightly attached to the top of the screen mounting box 1. When the display screen is not in use, start the motor 51 to drive the bidirectional threaded screw 52 to rotate at the output end, so that the two shift blocks 53 on the outer wall of the bidirectional threaded screw 52 are displaced opposite to each other on its outer wall. At this time, the angle between the two force plates 54 gradually increases, thereby driving the screen mounting plate 3 to move downward, causing the display screen to be placed in the screen mounting box 1. When the display screen is completely placed in the screen mounting box 1, its top cover 55 is tightly attached to the top of the screen mounting box 1 to form a sealed space, which can effectively protect the display screen from dust and other factors, help reduce damage to the display screen by external factors, and thus help extend its life.

[0028] refer to Figure 2-Figure 4 As shown, if the dust on the surface of the display screen is not cleaned when it is stored, the dust accumulated on the surface of the display screen for a long time will enter the interior of the display screen, causing damage to the electronic components. This is because the dust contains fine particles or chemicals, which cause corrosion or short circuits to the internal circuits and components of the display screen, thereby increasing the risk of damage to the display screen. In order to protect the display screen and ensure its normal operation and long-term use, the following settings are made: the screen cleaning mechanism 7 includes a belt 71 arranged on the right side of the screen mounting box 1, and the outer wall of the bidirectional threaded screw 52 away from the end of the motor 51 is fixedly connected to a pulley 1, and the pulley 1 is connected to the pulley through the belt 71. Second, the inner wall of pulley two is fixedly connected with a rotating drum 72, and the outer wall of rotating drum 72 is fixedly connected with a cylindrical brush 73 in contact with the surface of the display screen. When the display screen is placed in the screen loading box 1, the bidirectional threaded screw 52 rotates to drive pulley one to rotate, and the rotation of pulley one drives pulley two to rotate through belt 71, and the rotation of pulley two drives rotating drum 72 to rotate, so that the cylindrical brush 73 rotates and cleans the dust on the surface of the display screen when the display screen is placed in the screen loading box 1, so that the surface of the display screen is in a dust-free state after the display screen is placed in the screen loading box 1, which can effectively protect the display screen and extend its service life.

[0029] Example 2

[0030] Based on Example 1, Figure 2-Figure 4 After the cylindrical brush 73 cleans the dust on the surface of the display screen, if the dust on the surface of the cylindrical brush 73 is not cleaned in time, it will affect the cleaning effect of the screen next time. In order to ensure the cleaning effect of the screen next time, the following settings are made: a connecting plate 41 is fixedly connected to the right side of the screen mounting box 1, and a dust suction box 4 is fixedly connected to the side of the connecting plate 41 away from the screen mounting box 1. A cleaning brush mechanism 8 is provided at the inner bottom of the dust suction box 4 for adsorbing dust on the surface of the cylindrical brush 73 under the synchronous drive of the storage mechanism 5. The cleaning brush mechanism 8 includes a cam 81 fixed to the outer wall of the end of the bidirectional threaded screw 52 away from the motor 51, and a power plate 82 is movably connected to the side of the bottom end of the cam 81. A piston 83 is movably connected to the top of the power plate 82. The piston 83 is slidably sleeved in the interior of the dust suction box 4. A plurality of suction holes 85 are equidistantly arranged on the outer wall of the rotating drum 72. A one-way dust suction pipe 84 is fixedly connected to the end of the rotating drum 72 close to the dust suction box 4, and a one-way exhaust pipe 84 is fixedly connected to the top of the dust suction box 4. Dust pipe 86, one end of the one-way dust exhaust pipe 86 away from the dust suction box 4 is fixedly connected to a dust collecting box 87. The dust collecting box 87 is a prior art, a filter is arranged inside it and an air outlet is opened at its bottom. The dust collecting box 87 is fixedly installed on the side of the top of the dust suction box 4 away from the screen mounting box 1 by a buckle. When the two-way threaded screw 52 rotates, it will drive the cam 81 to rotate. The rotation of the cam 81 will push the power plate 82 to reciprocate and pull the piston 83. When the piston 83 moves downward, the one-way dust exhaust pipe 86 is closed and the one-way dust suction pipe 84 is opened. At this time, negative pressure is generated at the one-way dust suction pipe 84 to suck the dust cleaned from the surface of the cylindrical brush 73 into the dust suction box 4 through a number of suction holes 85. When the piston 83 moves upward, the one-way dust exhaust pipe 86 is opened and the one-way dust suction pipe 84 is closed. At this time, the dust in the dust suction box 4 is discharged into the dust collecting box 87 through the one-way dust exhaust pipe 86. This method can avoid bringing dust back to the surface of the display screen, thereby reducing the possibility of secondary pollution and improving the cleaning efficiency and effect of the display screen.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
