DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figures 1 to 4 A PC trolley case toughness testing device shown includes a base 1. A placement groove is chiseled on the base 1, the notch of the placement groove faces upward, and a PC trolley case 7 is placed in the placement groove. A support seat 2 is welded on the top of the base 1, and a rectangular slide groove 9 is cut out on the support seat 2 in the vertical direction, and a matching slider 10 is limited and slidably matched in the slide groove 9. A horizontal connecting plate 4 is welded and fixed on the slider 10, and a longitudinal pressing block 5 is fixedly connected to the bottom of the connecting plate 4. The longitudinal pressing block 5 is located above the placement groove of the base 1, and the longitudinal pressing block 5 squeezes the PC trolley case 7 in the vertical direction.

[0022] The support seat 2 is equipped with a driving mechanism, and the output end of the driving mechanism is connected to the slider 10 for driving the slider 10 to slide up and down along the slide slot 9. The driving mechanism includes a motor 3 and a first screw rod 8 as an output end. The motor 3 is a stepping motor and is bolted to the top of the support seat 2. The first screw rod 8 is vertically placed in the slide slot 9 and is rotatably connected to the support seat 2. The output shaft of the motor 3 rotates and penetrates into the support seat 2 and is coaxially fixedly connected to the first screw rod 8. The first screw rod 8 passes through the slider 10 and is threadedly connected to the slider 10.

[0023] The connecting plate 4 is slidably connected to a measuring rod 6, which passes through the connecting plate 4 in the vertical direction. A scale is engraved on the measuring rod 6 in the vertical direction to facilitate observation and measurement. The bottom and top ends of the measuring rod 6 are coaxially welded with a limit cap to prevent the measuring rod 6 from detaching from the connecting plate 4.

[0024] A clearance groove is chiseled on the base 1, and the clearance groove is connected to the placement groove. A transverse pressing block 15 is installed in the clearance groove, and two limit rods 17 are welded and fixed on the transverse pressing block 15. The two limit rods 17 are inserted into the base 1 in the horizontal direction and are limitedly slidably matched with the base 1. The transverse pressing block 15 is driven and matched with the first screw rod 8 through a linkage assembly, and is used to drive the transverse pressing block 15 to slide in the horizontal direction to approach or move away from the PC trolley case 7.

[0025] The base 1 is provided with a mounting groove 11, and the linkage assembly is assembled into the mounting groove 11. The linkage assembly includes a first bevel gear 13, a second bevel gear 14, an internal threaded sleeve 16, and a second screw rod 12. The second screw rod 12 slides horizontally into the clearance groove and is fixedly connected to the transverse pressing block 15. The internal threaded sleeve 16 is rotatably connected to the base 1 and is threadedly sleeved with the second screw rod 12. The first bevel gear 13 is fixedly sleeved on the internal threaded sleeve 16. It is used to drive the second screw rod 12 to slide horizontally toward or away from the PC trolley case 7.

[0026] The bottom end of the first screw rod 8 is inserted into the mounting groove 11, and the second bevel gear 14 is coaxially fixedly connected with the first screw rod 8. The first bevel gear 13 and the second bevel gear 14 are meshed and matched.

[0027] Working principle: When testing is required, the PC trolley case 7 is placed in the placement groove of the base 1, and one of the side walls of the PC trolley case 7 is fitted with the inner wall opposite to the placement groove and the transverse pressing block 15.

[0028] Then, the motor 3 is started, and the output shaft of the motor 3 drives the first screw 8 to rotate. The first screw 8 pushes the slider 10 to slide downward along the slide slot 9, and the slider 10 drives the connecting plate 4 to move downward synchronously. The connecting plate 4 drives the longitudinal pressing block 5 and the measuring rod 6 to move downward synchronously. During the downward movement of the longitudinal pressing block 5 and the measuring rod 6, the measuring rod 6 first contacts the top box body of the PC trolley case 7 and then slides relative to the connecting plate 4 after contacting the PC trolley case 7.

[0029] During this process, the first screw rod 8 drives the second bevel gear 14 to rotate. The second bevel gear 14 drives the first bevel gear 13 to rotate, and the first bevel gear 13 drives the internal threaded sleeve 16 to rotate, and the internal threaded sleeve 16 drives the second screw rod 12 to slide in the horizontal direction close to the PC trolley case 7. The second screw rod 12 drives the transverse pressing block 15 to move in the horizontal direction close to the PC trolley case 7.

[0030] When the longitudinal pressing block 5 contacts the top case of the PC suitcase 7, the transverse pressing block 15 contacts the side case of the PC suitcase 7. At this time, the motor 3 is turned off, and the scale on the measuring rod 6 where the bottom end surface of the connecting plate 4 is located is observed and recorded, and at the same time, the distance that the motor 3 pushes the slider 10 to slide downward through the first screw rod 8 is determined, that is, the height of the slider 10 at this time.

[0031] Next, the motor 2 is started for the second time, and the longitudinal pressing block 5 and the transverse pressing block 15 respectively press the PC trolley case 7 in the vertical direction and the horizontal direction. In this process, the PC trolley case 7 is deformed. When the deformation of the PC trolley case 7 reaches the predetermined value of the test, the motor 3 is shut down for the second time.

[0032] When the PC drawbar case 7 is deformed, the measuring rod 6 slides up and down following the top box body of the PC drawbar case 7 .

[0033] Then, the motor 3 is turned on for the third time, and the output shaft of the motor 3 drives the first screw 8 to reverse relative to the first time the motor 3 is started, and the first screw 8 pushes the slider 10 to slide up and slide up to the height where the slider 10 is when the longitudinal pressing block 5 just contacts the PC suitcase 7. At this time, the motor 3 is turned off for the third time. During this process, the second screw 12 drives the transverse pressing block 15 to move away from the PC suitcase 7 in the horizontal direction until it moves to the position where the transverse pressing block 15 is when the longitudinal pressing block 5 just contacts the PC suitcase 7.

[0034] Then wait for the PC suitcase 7 to recover. During the recovery process, the PC suitcase 7 will push the measuring rod 6 to slide. When the PC suitcase 7 recovers to a stable state, observe whether the scale on the measuring rod 6 where the bottom end face of the connecting plate 4 is located is different from the scale on the measuring rod 6 where the bottom end face of the connecting plate 4 is located when the longitudinal pressing block 5 and the top box body of the PC suitcase 7 just come into contact. If they are the same or the difference is small, it means that the PC suitcase 7 has a good toughness hinge. If they are different and the difference is large, it means that the PC suitcase 7 has a poor toughness hinge.

[0035] After the measurement is completed, the motor 3 is started for the fourth time, and the output shaft of the motor 3 drives the first screw rod 8 to rotate in the same direction as the third time, and the first screw rod 8 pushes the slider 10 to slide up and reset, and the slider 10 drives the connecting plate 4 to move up and reset. At the same time, the first screw rod 8 drives the second bevel gear 14 to rotate, the second bevel gear 14 drives the first bevel gear 13 to rotate, the first bevel gear 13 drives the internal threaded sleeve 16 to rotate, and the internal threaded sleeve 16 pushes the second screw rod 12 to slide in the horizontal direction away from the PC trolley case 7 and reset.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
