Description

Technical Field

[0001] The present application belongs to the field of computer software development technology, and in particular, relates to a computer software technology development demonstration device. Background Art

[0002] Computer software development refers to the process of developing computer programs, including stages such as requirements analysis, design, coding, testing and deployment. During this process, developers will use various software tools and techniques to create new software programs. When demonstrating the developed software, corresponding demonstration devices are often required.

[0003] The utility model with the existing authorization announcement number CN213361618U discloses a computer software technology development demonstration device. Through the setting of the rotating component, the gear one is rotated by rotating the handle, and the gear one drives the gear two to rotate, and the gear two can drive the display device to rotate, so as to achieve the angle adjustment. Through the setting of the lifting device, the driving motor drives the screw to rotate, and the screw pair converts the rotational motion of the screw into a linear reciprocating motion, thereby driving the connecting block to move, and the connecting block drives the moving sleeve block to move on the positioning support rod, so as to adjust the height of the display screen. Through the setting of the display device, the inclination angle of the display screen is controlled by the extension and retraction of two sets of telescopic hydraulic presses, which is convenient for users to use.

[0004] Although the above technical solution can adjust the tilt angle and height of the display screen, which increases the convenience of viewing, the display screen is exposed and lacks a screen protection structure, which makes the demonstration device easy to bump or accumulate dust when stored and affects subsequent use. In addition, there is a lack of a blackboard structure that is convenient for handwriting, which requires an additional writing board when the demonstration and explanation require additional writing of the explanation content, which is more troublesome.

[0005] Therefore, we propose a computer software technology development demonstration device to solve the above problems. Utility Model Content

[0021] 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 of the embodiments.

[0022] Reference Figure 1-4A computer software technology development demonstration device includes a storage box 1, a protective door 2 is arranged on the outside of the storage box 1, a display screen 3 is fixedly connected to the inner wall of the storage box 1, an I-shaped base 12 is arranged below the storage box 1, and two sets of universal wheels 13 are fixedly connected to the bottom surface of the I-shaped base 12. By providing the I-shaped base 12, other structures can be coordinated to provide stable support for the structure above it. By providing the universal wheels 13, the mobility of the bottom of the I-shaped base 12 can be increased, thereby facilitating the movement of the entire demonstration device.

[0023] A rotating rod 5 is fixedly connected to the inner wall of the storage box 1, and the inner wall of the protective door 2 is rotatably connected to the outer surface of the rotating rod 5. The top of the rotating rod 5 is fixedly connected to a limiting plate 6, and the bottom surface of the limiting plate 6 contacts the upper surface of the protective door 2. A multi-stage electric telescopic rod 14 is fixedly connected to the upper surface of the I-shaped base 12, and the telescopic end of the multi-stage electric telescopic rod 14 is fixedly connected to the bottom surface of the storage box 1. By providing the multi-stage electric telescopic rod 14, it can be extended and retracted when powered on, thereby playing a role in adjusting the height of the display screen 3.

[0024] The outer surface of the rotating rod 5 is threadedly connected with a hand-tightened nut tube 7, and the inner walls of the protective door 2 are respectively fixedly connected with a writing whiteboard 4, a holder 8 and a magnetic plate 10. The top of the hand-tightened nut tube 7 contacts the bottom surface of the protective door 2. The upper surface of the storage box 1 is fixedly connected with a pull shell 15, and the inner wall of the pull shell 15 is fixedly connected with a pull rod 16. By providing the pull shell 15 and the pull rod 16, the pull rod 16 can provide a rotating base surface for other hand-held structures to increase their flexibility of use. The two can cooperate with the above-mentioned hand-held structure to lift and carry the entire device.

[0025] A whiteboard pen 9 is clamped inside the holder 8, and a handle 17 is provided inside the pull shell 15. The inner wall of the handle 17 is rotatably connected to the outer surface of the pull rod 16. By providing the handle 17, the pull shell 15 can be rotated around the outer surface of the pull rod 16, so that the entire device can be lifted and carried by hand.

[0026] A magnetic whiteboard eraser 11 is provided on the outer side of the magnetic plate 10, and the back side of the magnetic whiteboard eraser 11 contacts the front side of the magnetic plate 10. A fixing rod 18 is fixedly connected to the left side of the storage box 1, and a clamping plate 20 is rotatably connected to the outer surface of the fixing rod 18. A limiting rod 19 is fixedly connected to the right side of the protective door 2. By providing the fixing rod 18 and the clamping plate 20, the clamping plate 20 can rotate around the outer surface of the fixing rod 18, and then after the protective door 2 and the storage box 1 are closed, the clamping plate 20 can be clamped with the limiting rod 19, thereby preventing the protective door 2 from being separated from the storage box 1 at will.

[0027] The working principle of the utility model is as follows: when in use, when the multi-stage electric telescopic rod 14 is retracted to the shortest, the storage box 1 and the protective door 2 are closed, and the card plate 20 is engaged with the limit rod 19, the whole device can be lifted by holding the handle 17, and the whole device can be carried in conjunction with the universal wheel 13. When the device is placed in a position convenient for computer software technology development and display, the card plate 20 is moved to rotate around the fixed rod 18 and then separated from the limit rod 19, and then the protective door 2 and the storage box 1 are flipped open to expose the display screen 3 and the writing whiteboard 4 respectively. At this time, after the display screen 3 is connected to the picture signal source, the multi-stage electric telescopic rod 14 is powered on and retracted to adjust the height of the display screen 3, and the hand-tightened nut tube 7 is threadedly rotated around the rotating rod 5 and then cooperated with the limit plate 6 to fix the position of the protective door 2. When it is necessary to adjust the display screen 3, the multi-stage electric telescopic rod 14 is powered on and retracted to adjust the height of the display screen 3. When the protective door 2 is used for writing, the whiteboard pen 9 is pulled out of the card holder 8 and then written on the writing whiteboard 4 with the whiteboard pen 9. When it is necessary to erase the words written by the whiteboard pen 9 on the writing whiteboard 4, the magnetic whiteboard eraser 11 is removed from the magnetic plate 10 and erased with the magnetic whiteboard eraser 11. When the display screen 3 is stored thereafter, the hand-tightened nut tube 7 is loosened, so that the protective door 2 is rotated around the rotating rod 5 and then closed with the storage box 1, and the card plate 20 is engaged with the limit rod 19. The design of the entire computer software technology development demonstration device effectively solves the problem that the demonstration device is easily bumped or dust is accumulated during storage and placement due to the lack of a screen protection structure, which affects subsequent use, and the problem that an additional writing board needs to be configured when the demonstration and explanation need to be additionally written due to the lack of a blackboard structure that is convenient for handwriting, which is more troublesome.
