Description

Technical Field

[0001] The present invention relates to the field of software development and testing equipment, and in particular to a multi-screen testing device for computer software development. Background Art

[0002] Software development is the process of building a software system or software component of a system according to user requirements. Software development is a systematic engineering process encompassing requirements capture, analysis, design, implementation, and testing. Software testing is an activity used to facilitate the verification of software's correctness, integrity, security, and quality. In other words, software testing is the process of reviewing or comparing actual output with expected output. The classic definition of software testing is: the process of operating a program under specified conditions to detect errors, measure software quality, and evaluate whether it meets design requirements.

[0003] The patent document with the announcement number CN221884298U discloses a multi-screen testing device for computer software development, including a fixed frame, a second fixed plate, a placement box and a first fixed plate. The front front of the fixed frame is movably connected to a plurality of groups of turntables, and the rear end of the fixed frame is provided with a plurality of groups of servo motors, wherein the position of the servo motor corresponds to the turntable, and the front end of the servo motor is provided with a rotating shaft, wherein the rotating shaft runs through the fixed frame, and the front end is fixedly connected to the turntable, and the front end of the turntable is provided with a placement box, and the placement box is provided with two groups of left and right first fixed plates, and a second fixed plate is provided below the first fixed plate, and a spring plate is provided in the middle of the placement box, and a plurality of groups of telescopic springs are provided at the rear end of the spring plate, wherein the front end of the telescopic spring is provided with a plurality of telescopic springs. It is fixedly connected to the spring plate, and the rear end is fixedly connected to the placement box. Two sets of upper and lower first spring rods are provided on one side of the first fixed plate, and a second spring rod is provided at one end of the first fixed plate, wherein the second spring rod passes through the second fixed plate. Although the above application document uses a servo motor to drive the rotating shaft to rotate, the rotating shaft drives the turntable to rotate, and the turntable drives the placement box to rotate, thereby adjusting the direction of the tablet computer to make it suitable for software that requires adjustment between horizontal and vertical screens, thereby further ensuring the detection effect, but in the process of using spring clamping, frequent clamping / release operations will cause metal fatigue of the spring (especially the telescopic spring 18 and the coil spring in the spring rod), and the elastic coefficient will decrease, resulting in insufficient clamping force, loosening of the equipment or even falling off.

[0023] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] Example 1, see Figure 1-Figure 4 , this embodiment provides a computer software development multi-screen testing device, including a base 5, the front of the base 5 is equipped with an electric rotating rod 6, and the front of the electric rotating rod 6 is equipped with a fixed plate 1; A moving block 21 is movably passed through the bottom of the fixed plate 1, and an elastic telescopic rod 210 is fixedly connected to the top of the inner wall of the fixed plate 1. A groove is provided at the top of the moving block 21, and a slide rail 22 is installed on the side of the groove. A slide rod 25 is slidably connected to the inner wall of the slide rail 22, and a clamping plate 23 is fixedly connected to the side of the slide rod 25. A limiting rod 26 is fixedly connected to the bottom of the inner wall of the moving block 21, and the two limiting rods 26 are fixedly connected by a fixed rod 27. A spring 211 is fixedly connected to the back of the slide rail 22, and a reduction pulley 24 is fixedly connected to the front of the clamping plate 23. A fixing device 3 for limiting the tablet data cable is installed on the front of the fixed plate 1, and a pneumatic device 4 for blowing air to dissipate heat and clean dust on the tablet is installed on the front of the fixed plate 1. The fixed plate 1 is driven to rotate by the electric rotating rod 6 on the base 5 to adjust the position of the tablet. The movable block 21 at the bottom of the fixed plate 1 can move up and down under the action of the elastic telescopic rod 210. The sliding rail 22 at the top of the movable block 21 slides inside the connecting rod 25, and the connecting rod 25 is connected to the clamping plate 23. Through the cooperation of the sliding rail 22 and the connecting rod 25, the clamping plate 23 can move left and right to clamp the tablet. The limiting rod 26 and the fixed rod 27 prevent the connecting rod 25 from sliding excessively. The spring 211 provides elastic force so that the clamping plate 23 can adapt to tablets of different sizes. The reduction pulley 24 controls the movement speed of the connecting rod 25 to ensure a smooth clamping process. The fixing device 3 limits the tablet data cable through the fixing block 35 and the rotating rod 36. The hydraulic component uses the hydraulic principle to control the expansion and contraction of the rack 34 through the cooperation of the airbag 31 and the hydraulic tank 33, thereby driving the circular gear 310 to rotate, driving the rotating rod 36 to rotate, so that the wiring harness limiting block 37 can flexibly limit and fix the data cable. The pneumatic device 4 drives the reciprocating screw 43 to rotate through the meshing transmission of the first bevel gear 42 and the second bevel gear 44, so that the sleeve 45 makes a linear motion on the reciprocating screw 43, thereby driving the moving rod 46 to move back and forth in the air cylinder 48, realizing intermittent air discharge from the air cylinder 48, and effectively blowing air to dissipate heat and clean dust on the flat plate. The two ends of the spring 211 are respectively fixedly connected to the back of the slide rail 22 and the front of the slide rod 25. The top of the moving block 21 is fixedly connected with a card rod 28. The two ends of the spring 211 are respectively fixed to the back of the slide rail 22 and the front of the slide rod 25. The elastic force of the spring 211 enables the slide rod 25 to slide flexibly in the slide rail 22, so that the clamping force of the clamping plate 23 on the flat plate can be adjusted.The clamping rod 28 at the top of the moving block 21 is fixedly connected to a rubber sleeve 29, and the friction of the rubber sleeve 29 further fixes the position of the moving block 21, preventing it from sliding during use and ensuring the stability of the clamping. The outer wall of the clamping rod 28 is fixedly connected to a rubber sleeve 29. The shape of the clamping rod 28 is L-shaped. The rubber sleeve 29 on the outer wall of the clamping rod 28 increases the friction. The design of the L-shaped clamping rod 28 enables it to better fix the position of the moving block 21, preventing the moving block 21 from shifting during the clamping process, ensuring the reliability of the clamping. The moving block 21 has two clamping rods 28, and a clamping block is fixedly connected to the front of the moving block 21. The top of the elastic telescopic rod 210 is fixedly connected to the bottom of the clamping block. The moving block 21 has two clamping rods 28, which enhances the fixing effect of the position of the moving block 21. The connection between the clamping block on the front of the moving block 21 and the top of the elastic telescopic rod 210 enables the elastic telescopic rod 210 to better exert its elastic effect, adapt to flat plates of different thicknesses, and ensure the stability of the clamping.

[0025] When the above-mentioned device is used, the head of the test plate is inserted into the inner wall of the top moving block 21, and the bottom of the test plate is inserted into the inner wall of the bottom moving block 21. The test plate drives the bottom moving block 21 to descend by its own weight. The moving block 21 descends and squeezes the elastic telescopic rod 210 through the card block. The moving block 21 descends and drives the slide bar 25 to descend. The slide bar 25 is set by the limit rod 26. The slide bar 25 drives the two clamping plates 23 to move relative to each other. The spring 211 is stretched, and the clamping plate 23 drives the reduction pulley 24 to fix the test plate. The bottom moving block 21 descends and drives the card bar 28 to descend. The bottom card bar 28 drives the card bar 28 of the top moving block 21 to descend. The slide bar 25 of the top moving block 21 is driven to move relatively through the limit rod 26, and the slide bar 25 drives the clamping plate 23 to fix the top of the test plate. The bottom clamping rod 28 is inserted into the inner wall of the rubber sleeve 29 on the outer wall of the top clamping rod 28, and the top clamping rod 28 is inserted into the inner wall of the rubber sleeve 29 on the outer wall of the bottom clamping rod 28. The electric rotating rod 6 is started, and the electric rotating rod 6 drives the fixed plate 1 to rotate. Whenever the fixed plate 1 is rotated to forty-five degrees, the gravity of the test plate will be shared. However, due to the action of the rubber sleeve 29, the two clamping rods 28 will not separate immediately due to the friction of the rubber sleeve 29. When the fixed plate 1 is rotated ninety degrees, the plate will be adjusted to the inner wall of another set of moving blocks 21. The test plate can be slowly lowered by the reduction pulley 24, and the test plate can be re-fixed, so that the two sets of moving blocks 21 can fix the test plate in batches. When the test plate needs to be removed, the electric rotating rod 6 is rotated forty-five degrees to make the clamping rod 28 slide out from the inside of the rubber sleeve 29.

[0026] Example 2, see Figures 1-6On the basis of embodiment 1, the fixing device 3 includes a fixing block 35, the right side of the fixing block 35 is rotatably connected to a rotating rod 36, the outer wall of the rotating rod 36 is fixedly connected to a wiring harness limiting block 37, the inner wall of the wiring harness limiting block 37 is rotatably connected to a plurality of rotating beads 38, the bottom of the inner wall of the fixing plate 1 is fixedly connected to a hydraulic component, the side of the fixing block 35 is fixedly connected to a vertical rod 39, and the outer wall of the rotating rod 36 is fixedly sleeved with a circular gear 310. The fixing device 3 limits the tablet data cable through the fixing block 35 and the rotating rod 36, and the wiring harness limiting block 37 outside the rotating rod 36 is rotatably connected to a plurality of rotating beads 38. The setting of the rotating beads 38 enables the wiring harness limiting block 37 to rotate flexibly to adapt to data cables of different diameters and prevent the data cables from loosening or falling off during use. The hydraulic assembly at the bottom of the inner wall of the fixed plate 1 cooperates with the airbag 31 and the hydraulic tank 33 to control the extension and contraction of the rack 34 using the hydraulic principle, thereby driving the circular gear 310 to rotate, driving the rotating rod 36 to rotate, and realizing flexible limiting and fixation of the data cable. The hydraulic assembly includes an airbag 31, which is fixedly connected to the back of the fixed plate 1, and a connecting hose 32 is fixedly connected to the back of the airbag 31. The bottom of the inner wall of the fixed plate 1 is fixedly connected to the hydraulic tank 33, and the piston at one end inside the hydraulic tank 33 is slidingly connected to the rack 34. The circular gear 310 and the rack 34 engage with each other, and the end of the connecting hose 32 away from the airbag 31 is fixedly connected to the back of the hydraulic tank 33. The pressure change in the hydraulic tank 33 is controlled by the inflation and deflation of the airbag 31, thereby driving the extension and contraction of the rack 34, and then driving the circular gear 310 to rotate, realizing rotation control of the rotating rod 36, and ensuring that the limiting and fixation of the data cable are more flexible and reliable.

[0027] When the above-mentioned equipment is in use, when the bottom clamping rod 28 drives the top clamping rod 28 to descend, the airbag 31 between the two clamping rods 28 will be squeezed. After the airbag 31 is squeezed, the internal pressure of the connecting hose 32 and the hydraulic tank 33 increases, driving the rack 34 to move toward the front, and the rack 34 drives the circular gear 310 to rotate, and the circular gear 310 drives the rotating rod 36 to rotate, and the rotating rod 36 drives the wiring harness limit block 37 to rotate. The data cable of the test plate is limited by cooperating with the vertical rod 39 to prevent the data cable from damaging the interface of the test plate when the fixed plate 1 rotates. The data cable can be moved left and right on the inner wall of the wiring harness limit block 37 through the rotating bead 38 inside the wiring harness limit block 37.

[0028] Example 3, see Figure 1-Figure 7Based on the first embodiment, the pneumatic device 4 includes a collar 41, which is fixedly connected to the front of the base 5.

A cylinder 48 is fixedly connected to the side of the side plate 47. The inner wall of the cylinder 48 is slidably connected to a moving rod 46 via a piston. The collar 41 is fixed to the front of the base 5. The first bevel gear 42 on the front of the fixed plate 1 meshes with the second bevel gear 44. The bevel gears drive the reciprocating screw 43 to rotate. The cylinder 48 on the side of the side plate 47 is slidably connected to the moving rod 46 via a piston. The reciprocating screw 43 is threadedly connected to the sleeve 45. The right side of the sleeve 45 is fixedly connected to the left side of the moving rod 46. Through the rotation of the reciprocating screw 43, the sleeve 45 makes a linear motion on the reciprocating screw 43, thereby driving the moving rod 46 to reciprocate in the air cylinder 48, realizing intermittent air discharge of the air cylinder 48, effectively blowing air to dissipate heat and clean dust on the flat plate, improving the heat dissipation effect and service life of the equipment during the test. The left side of the inner wall of the ring 41 is rotatably connected to the reciprocating screw 43 through a bearing, and the right side of the reciprocating screw 43 is fixedly connected to the second bevel gear 44. The reciprocating screw 43 is threadedly connected to the sleeve 45, and the right side of the sleeve 45 is fixedly connected to the left side of the moving rod 46. The left side of the inner wall of the ring 41 is rotatably connected to the reciprocating screw 43 through a bearing, and the right side of the reciprocating screw 43 is fixedly connected to the second bevel gear 44. The reciprocating screw 43 is driven to rotate by the meshing transmission of the first bevel gear 42 and the second bevel gear 44. The reciprocating screw 43 is threadedly connected to the sleeve 45, and the right side of the sleeve 45 is fixedly connected to the left side of the moving rod 46, so that when the sleeve 45 makes a linear motion on the reciprocating screw 43, it can drive the moving rod 46 to move back and forth in the air cylinder 48, thereby realizing intermittent air discharge from the air cylinder 48, effectively blowing air to dissipate heat and clean dust on the flat panel, ensuring the heat dissipation and cleaning of the flat panel during the test, and improving the accuracy of the test and the service life of the equipment.

[0029] When the above-mentioned equipment is in use, the electric rotating rod 6 drives the fixed plate 1 to rotate, the fixed plate 1 drives the first bevel gear 42 to rotate, the first bevel gear 42 drives the second bevel gear 44 to rotate, the second bevel gear 44 drives the reciprocating screw 43 to rotate, the reciprocating screw 43 drives the sleeve 45 to rotate, the sleeve 45 drives the moving rod 46 to move to the left, the moving rod 46 drives the piston to absorb air from the air cylinder 48, when the sleeve 45 moves to the right, the moving rod 46 drives the piston to move to the right, so that the gas inside the air cylinder 48 is ejected and blown to the front of the test plate, which can not only dissipate heat for the test plate but also clean the dust on the front of the test plate.

[0030] When the above-mentioned device is used in a specific manner, the above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
