DETAILED DESCRIPTION

[0017] The utility model will be further described in combination with the drawings.

[0018] Please refer to Figs. 1-3The illustrated luggage pressure testing device includes a base plate 1, a support 2, a top plate 3, a hydraulic push rod 4, a main pressure plate 5, and a luggage body 6. The base plate 1, support 2, top plate 3, hydraulic push rod 4, and main pressure plate 5 form a pressure testing machine. A signal transmitter 7 is fixedly connected to one side of the main pressure plate 5, transmitting signals to a display device to show the pressure data of the luggage body 6. A first groove 8 is formed at the center of the bottom of the main pressure plate 5. Electric push rods 9 are fixedly connected to both sides of the first groove 8, which are far apart from each other. The extension of the electric push rods 9 changes the distance between the two first vertical plates 10 to adapt to the thickness of the luggage body 6. Then, the second vertical plate 11 is adjusted to connect with the first vertical plate 10, allowing it to fit the width of the luggage body 6. The electric push rod 9 is fixedly connected to a first vertical plate 10 at its output end. The upper end of the first vertical plate 10 contacts the first groove 8. The first groove 8 contacts a second vertical plate 11. The first vertical plate 10 and the second vertical plate 11 are evenly provided with yin and yang grooves. The bottom ends of the first vertical plate 10 and the second vertical plate 11 are in contact with the upper side of the suitcase body 6. The bottom plate 1 is provided with a second groove 12. Two limiting rods 13 are fixedly connected in the second groove 12. A pad 14 is sleeved on the limiting rod 13. The upper end of the pad 14 contacts the suitcase body 6. By setting the limiting rod 13, the pad 14 is limited on the bottom side of the pad 14. At the same time, multiple sets of pads 14 can be filled in the second groove 12 and multiple pads 14 can contact each other, thereby forming a contact surface with the bottom side of the suitcase body 6.

[0019] The pad 14 has a through hole on its upper side and a connecting rod 15 is inserted into the through hole. A contact block 16 is fixedly connected to the upper end of the connecting rod 15. By setting the connecting rod 15 and the contact block 16, the bottom side of the suitcase body 6 can be contacted by climbing the highest point of the pad 14. This increases the contact area and also prevents the pad 14 from contacting the pulleys on the bottom side of the suitcase body 6.

[0020] The pad 14 has a limiting groove 17 on both sides, and a limiting plate 18 contacts the limiting groove 17. The limiting plate 18 is fixedly connected to the limiting rod 13. By setting the limiting rod 13 and the limiting plate 18, the limiting support of the pad 14 can be provided to maintain the stability of the multiple pads 14 in the second groove 12.

[0021] The upper side of the limiting groove 17 has a hemispherical structure, and the thickness of the limiting groove 17 is half that of the limiting plate 18. The limiting plate 18 can be hidden when the two pads 14 come into contact, thereby increasing the contact surface between the pads 14 and improving stability.

[0022] The second vertical plate 11 has a recess 20 on the upper side of the yin-yang groove. A magnetic strip 19 is in contact with the recess 20. The magnetic strip 19 is fixedly connected to both sides of the upper end of the first vertical plate 10. By setting the magnetic strip 19, the recess 20 can be connected while the second vertical plate 11 is stably in contact with the first vertical plate 10.

[0023] Working principle: Based on the width and thickness of the suitcase body 6, the electric push rod 9 extends, causing the two first vertical plates 10 to move relative to each other. Then, the second vertical plate 11 is adjusted to connect with the first vertical plate 10 according to the gap. At this time, the recess 20 corresponds to and contacts the magnetic strip 19. Then, the pad 14 is added or removed, and the contact block 16 is added or removed according to the position of the bottom pulley of the suitcase body 6. The contact surface between the suitcase body 6 and the pad 14 and the contact block 16 is increased, which can improve the stability of the suitcase body 6 on the bottom plate 1. Then, the hydraulic push rod 4 causes the main pressure plate 5 to press down and performs a pressure resistance test on the suitcase body 6.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
