[0026] The sliding support tooth is configured to cooperate with the adjusting support rack.

[0027] This invention provides a software development demonstration screen device. It has the following beneficial effects:

[0028] This invention allows for the portable movement of easily damaged display screens by installing the main screen inside a screen mounting box and storing the display screen in an openable and foldable base box. Furthermore, two flip-up extended screens are provided on both sides of the main screen, facilitating split-screen display of source code for different parts of software development, comparison, and repair. The foam pads inside the base box provide cushioning and protection for the folded flip-up extended screens. When in use, the display screen is supported by a rear-end screen unfolding support component. Opening the dust cover for the connecting cable and pressing the external cable retraction component allows for easy and quick connection to the data host.

[0029] The device works by pressing the rotating take-up head in the external cable take-up assembly. This causes the lower pressure spring to compress the trigger return spring between the pressure spring and the abutment spring, causing it to retract. This retraction is transmitted through the trigger connecting rod, which moves the lower retraction engagement head downward. This causes the retraction engagement tooth to bend towards the center, restricted by the side wall of the engagement groove. This disengages the outer retraction engagement tooth from the engagement tooth ring, allowing the rotating take-up base kit to rotate independently of the rotating take-up head. Even if the rotating take-up head is not rotating, the external cable can be pulled out of the take-up hole. When the rotating take-up head is not pressed, the force of the return spring causes the retraction engagement head to move upward, allowing the retraction engagement tooth to engage with the engagement tooth ring again. At this point, rotating the rotating take-up head can rewind the external cable, achieving the take-up effect.

[0030] In this process, by pushing the sliding adjustment component in the screen unfolding support assembly, the sliding support tooth in it sweeps across the adjustment support rack. Since the cross-sections of the sliding support tooth and the adjustment support rack are both right-angled trapezoids, their oblique waist contact during sliding can push the floating limit spring at the upper end. When the support foot supports it, the right-angled surfaces of the sliding support tooth and the adjustment support rack will come together to form support.

[0031] When retraction is needed, simply pull the adjustment handle to make the sliding support teeth and the adjusting support rack interlock, and it will slide upward to achieve the retraction effect, which is more convenient and faster than current display devices. Attached Figure Description

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] like Figures 1 to 2 As shown, this embodiment of the invention provides a software development demonstration screen device, including a screen mounting base box 1. The screen mounting base box 1 has a screen placement slot 2 inside. Two external screen cable recycling components 3 are arranged at the inner corner of the screen placement slot 2. A junction box 5 is fixedly installed inside the screen placement slot 2, and several display screen connection cables 6 are electrically connected to the junction box 5. A sponge pad 11 is fixedly installed in the middle of the screen placement slot 2. A screen mounting box 7 is rotatably connected to one end of the screen mounting base box 1, and a main screen is fixedly installed inside the screen mounting box 7. The screen 9 has a screen unfolding support component 8 on its outer side, a handle 12 rotatably mounted on the front side of the screen mounting base box 1, and dust covers 4 for connecting cables on both sides of the rear side of the screen mounting base box 1. The main screen 9 has flip-up extended screens 10 rotatably mounted on both sides, and extended screen buckles 13 are fixedly mounted on the outer side of each of the two flip-up extended screens 10. A rotating buckle 14 is rotatably fitted onto one of the extended screen buckles 13. The two flip-up extended screens 10 are electrically connected to the display screen connecting cable 6.

[0048] Through the above technical solution, by installing the main screen 9 inside the screen mounting box 7 and storing the display screen in the opening and closing mechanism of another screen mounting base box 1, the easily damaged display screen can be moved portablely. Furthermore, two flip-up extended screens 10 are provided on both sides of the main screen 9, which facilitates split-screen display of the source code of various parts of software development, comparison, display, and repair. The sponge pad 11 inside the screen mounting base box 1 can provide cushioning protection for the folded flip-up extended screens 10. When in use, the display screen can be supported by the screen unfolding support component 8 at the rear. Then, by opening the dust cover 4 of the connecting cable, pressing the screen external cable retraction component 3, and pulling out the data cable, it can be connected to the data host, which is convenient and quick.

[0049] like Figure 1 , Figures 3 to 6As shown, the screen external cable recycling assembly 3 includes: a base plate 301, a rotating base 302, a rotating recycling head 303, a cable take-up box 304, a cable take-up hole 305, a pressure spring 306, a trigger connecting rod 307, a retaining spring 308, a junction box connecting wire 309, a trigger reset spring 310, an external connecting wire 311, a rotating cable take-up base kit 312, a retraction engagement head 313, a retraction engagement toothed rod 314, a retraction engagement tooth 315, an engagement groove 316, and an engagement toothed ring 317; the screen swing... The bottom of the trough 2 is provided with a bottom box upper plate 301. A rotating base 302 is fixedly installed on the upper end of the bottom box upper plate 301. A rotating recovery head 303 is provided above the rotating base 302. A pressure spring 306 is fixedly installed on the lower side of the rotating recovery head 303. A trigger connecting rod 307 is fixedly connected to the lower end of the rotating recovery head 303. A retraction engagement head 313 is fixedly connected to the lower end. Several retraction engagement teeth 314 are integrally provided on the side of the retraction engagement head 313. Each retraction... The upper side of the meshing gear 314 is integrally provided with retractable meshing teeth 315; a retaining spring 308 is fixedly installed on the lower end of the inner wall of the rotating base 302, and a trigger reset spring 310 is sleeved on the trigger connecting rod 307 between the retaining spring 308 and the pressure spring 306; a take-up box 304 is fixedly installed on the lower end of the bottom box upper plate 301, a take-up hole 305 is opened on one side of the take-up box 304, and a rotating take-up base kit 312 is rotatably installed on the lower inner wall of the take-up box 304. The rotating take-up base assembly 312 has an engagement groove 316 inside, and an engagement tooth ring 317 is provided on the side wall of the engagement groove 316; a junction box connecting line 309 is provided at the lower end of the engagement groove 316, and the junction box connecting line 309 passes through the side wall of the rotating take-up base assembly 312 and is connected to an external connecting line 311; the retraction engagement head 313 is provided in the engagement groove 316; the retraction engagement tooth 315 is configured to cooperate with the engagement tooth ring 317; and the junction box connecting line 309 is electrically connected to the junction box 5.

[0050] like Figure 5 , Figures 7 to 10As shown, the rotating take-up base kit 312 includes: a rotating take-up drum 3121, a rotating take-up base 3122, a cable management groove 3123, a locking groove 3124, a locking slider 3125, a locking spring 3126, and a locking tooth groove 3127. The rotating take-up base 3122 is fixedly installed on the lower inner wall of the take-up box 304. The rotating take-up drum 3121 is rotatably mounted on the rotating take-up base 3122. Several cable management grooves 3123 are integrally provided on the side of the rotating take-up drum 3121. The upper surface of the rotating take-up base 3122 is provided with a locking tooth groove 3127. Several locking grooves 3124 are provided at the lower end of the rotating take-up base 3122 and directly above the locking tooth groove 3127. A locking slider 3125 is slidably disposed in each locking groove 3124. A locking spring 3126 is provided on the upper end of the locking slider 3125.

[0051] Through the above technical solution, by pressing the rotating recycling head 303 in the external wiring recycling assembly 3, the lower end pressure spring 306 can compress the trigger return spring 310 between the spring and the abutment spring 308, causing it to retract. This retraction is transmitted through the trigger connecting rod 307, triggering the lower end retraction engagement head 313 to move downward. This allows the retraction engagement tooth 314 to bend towards the center, restricted by the side wall of the engagement groove 316, thereby disengaging the outer end retraction engagement tooth 315 from the engagement tooth ring 317. The rotating take-up base kit 312 can rotate independently of the rotating take-up head 303. Even if the rotating take-up head 303 is not rotating, the external connecting cable 311 can be pulled out from the take-up hole 305. When the rotating take-up head 303 is not pressed, the retraction engagement head 313 can be moved upward by the force of the reset spring 310, so that the retraction engagement tooth 315 engages with the engagement tooth ring 317 again. At this time, rotating the rotating take-up head 303 can rotate and rewind the external connecting cable 311 to achieve the effect of recycling.

[0052] The locking slider 3125 slides within the locking tooth groove 3127. During the sliding process, the teeth within the locking tooth groove 3127 and the locking spring 3126 at the upper end provide intermittent and continuous damping to the rotating take-up drum 3121, preventing the data cable from springing back due to the toughness of the material.

[0053] like Figure 2 , Figure 11As shown, the screen unfolding support assembly 8 includes: an adjustment groove 801, an adjustment support rack 802, a sliding adjustment member 803, a support plate 804, a support foot 805, and a support foot retraction limiting plate 806; the screen mounting box 7 has an adjustment groove 801 on its outer surface, the adjustment support rack 802 is integrally provided on the inner surface of the adjustment groove 801, the sliding adjustment member 803 is slidably provided in the adjustment groove 801, the support plate 804 is rotatably provided at the lower end of the sliding adjustment member 803, the support foot 805 is rotatably provided at the lower end of the support plate 804, and the support foot retraction limiting plate 806 is integrally provided on both sides of the support foot 805, and the support foot retraction limiting plate 806 is configured to cooperate with the adjustment groove 801.

[0054] like Figure 11 , Figures 12 to 13 As shown, the sliding adjustment component 803 includes: an upper adjustment plate 8031, an adjustment handle 8032, an adjustment limiting pad 8033, a floating limiting plate 8034, a floating limiting spring 8035, and a sliding support tooth 8036; the upper adjustment plate 8031 ​​is slidably provided with the adjustment handle 8032, and both ends of the adjustment handle 8032 and located above the upper adjustment plate 8031 ​​are integrally provided with adjustment limiting pads 8033; the lower end of the adjustment handle 8032 is fixedly connected to the floating limiting plate 8034, and both ends of the adjustment handle 8032 and located between the adjustment handle 8032 and the floating limiting plate 8034 are sleeved with floating limiting springs 8035; the lower surface of the floating limiting plate 8034 is integrally provided with a sliding support tooth 8036, and the sliding support tooth 8036 is configured to cooperate with the adjustment support rack 802.

[0055] Through the above technical solution, by pushing the sliding adjustment member 803 in the screen unfolding support assembly 8, the sliding support tooth 8036 in it sweeps across the adjustment support rack 802. Since the cross-sections of the sliding support tooth 8036 and the adjustment support rack 802 are both right-angled trapezoids, their oblique waist contact during sliding can push the upper floating limit spring 8035. When the support foot 805 supports, the right-angled surfaces of the sliding support tooth 8036 and the adjustment support rack 802 will abut together to form support.

[0056] When it is time to retract, simply pull the adjusting handle 8032 to make the sliding support tooth 8036 and the adjusting support rack 802 interlock, and it can slide upward to achieve the effect of retraction, which is more convenient and faster than current display devices.

[0057] Working principle:

[0058] This invention allows for the portable movement of easily damaged display screens by installing the main screen 9 inside the screen mounting box 7 and storing the display screen in the opening and closing mechanism of another screen mounting base box 1. Furthermore, two flip-up extended screens 10 are provided on both sides of the main screen 9, facilitating the split-screen display of the source code of various parts of software development, comparison, display, and repair. The sponge pad 11 inside the screen mounting base box 1 can provide cushioning and protection for the folded flip-up extended screens 10. When in use, the display screen can be supported by the screen unfolding support component 8 at the rear. Then, by opening the dust cover 4 of the connecting cable, pressing the screen external cable retraction component 3, and pulling out the data cable, it can be connected to the data host, which is convenient and quick.

[0059] Specifically, by pressing the rotating retraction head 303 in the external wiring retraction assembly 3, the lower end pressure spring 306 compresses the trigger reset spring 310 between the lower end pressure spring and the abutment spring 308, causing it to retract. This retraction is transmitted through the trigger connecting rod 307, triggering the lower end retraction engagement head 313 to move downward. This causes the retraction engagement tooth 314 to bend towards the center, restricted by the side wall of the engagement groove 316, thereby disengaging the outer end retraction engagement tooth 315 from the engagement tooth ring 317, allowing the rotation... The take-up base kit 312 can rotate independently of the rotating take-up head 303. Even if the rotating take-up head 303 is not rotating, the external connecting cable 311 can be pulled out from the take-up hole 305. When the rotating take-up head 303 is not pressed, the retraction engagement head 313 can be moved upward by the force of the return spring 310, so that the retraction engagement tooth 315 engages with the engagement tooth ring 317 again. At this time, rotating the rotating take-up head 303 can rotate and rewind the external connecting cable 311 to achieve the effect of retraction.

[0060] In this process, by pushing the sliding adjustment member 803 in the screen unfolding support assembly 8, the sliding support tooth 8036 in it sweeps across the adjustment support rack 802. Since the cross-sections of the sliding support tooth 8036 and the adjustment support rack 802 are both right-angled trapezoids, their oblique waist contact during sliding can push the upper floating limit spring 8035. When the support foot 805 supports, the right-angled surfaces of the sliding support tooth 8036 and the adjustment support rack 802 will abut together to form support.

[0061] When it is time to retract, simply pull the adjusting handle 8032 to make the sliding support tooth 8036 and the adjusting support rack 802 interlock, and it can slide upward to achieve the effect of retraction, which is more convenient and faster than current display devices.

[0062] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
