Description

Technical Field

[0001] The utility model relates to the technical field of trolley cases, in particular to a high-pressure-bearing and wear-resistant ABS composite board trolley case. Background Art

[0002] A trolley case is a suitcase with a trolley and wheels. It is widely used because of its convenience. At the same time, a trolley case is also divided into single-tube trolleys and double-tube trolleys because the case has a trolley. The tube of the trolley is also divided into square tubes and round tubes, which is convenient for dragging while walking, greatly reducing the burden. Trolley cases can be carried by hand or dragged. The wheels of the trolley cases we usually use are basically located at the bottom of the case.

[0003] There is currently a high-pressure-bearing and wear-resistant ABS composite board trolley case (application number: 201922375493.8) with good fireproof effect. The moisture-proof layer is made of polytetrafluoroethylene film, which is acid-resistant, alkali-resistant, and resistant to various organic solvents. It is almost insoluble in all solvents and has good waterproof performance. The above-mentioned problem still exists. When people travel daily, they often use trolley cases to put clothes and items into the trolley cases. However, when using the trolley cases, the trolley cases are often squeezed, which can easily cause damage to the items inside the trolley cases and the trolley cases themselves. When the above-mentioned device increases the pressure-bearing capacity of the trolley cases, a reinforcing strip is set on the outside of the trolley cases, and the reinforcing strip is set on the outside of the trolley cases. When the suitcase is squeezed by the boxes above and below, it is easy to cause the upper and lower parts of the suitcase to deform backwards, which is not convenient for increasing the pressure-bearing capacity of the suitcase in the upper and lower directions, and thus easily causes damage to the suitcase itself and the items inside. In addition, when using the suitcase, it is often necessary to place the suitcase horizontally. At this time, the position in contact with the ground is easily subject to wear. The above-mentioned device is provided with a raised portion on the outside of the suitcase to enhance the wear resistance. Although the wear resistance can be increased, the raised portion will also experience certain wear after long-term use, which easily affects the appearance and wear resistance of the suitcase, and is not convenient for the staff to disassemble the wear-resistant pad, and thus is not convenient for the wear-resistant pad to be replaced.

[0023] A straight block 10 is fixedly connected to one side of the front end face of the plate body 9, and a groove block 11 is matched with the outer wall gap of the straight block 10. When the groove block 11 is subjected to force, it can move up and down on the outer wall of the straight block 10. The lower rear end of the groove block 11 is fixedly connected to one side of the front end face of the wear-resistant pad 13, and a straight cylinder 12 is fixedly connected to the upper side of one side of the groove block 11. A screw rod 14 is threadedly connected to the inner wall of one end of the straight cylinder 12, and one end of the screw rod 14 is rotatably connected to an insertion rod 15 through a bearing. The bearing allows the screw rod 14 to rotate at one end of the insertion rod 15 when the force is applied. One side of the outer wall of the insertion rod 15 is matched with the gap between the groove on the upper side of one side of the groove block 11 and the groove at one end of the straight block 10. A pressure-bearing structure 2 is provided on one side of the bracket 8. The pressure-bearing structure 2 is convenient for increasing the pressure-bearing capacity of the trolley case in the up and down directions to avoid damage to the trolley case itself and the items inside.

[0024] The pressure-bearing structure 2 includes a square plate 2a2, one end of the upper and lower square plates 2a2 are respectively fixedly connected to the upper and lower sides of the inner wall of the box body 1, and a rod body 2a3 is fixedly connected to one side of the top of the lower square plate 2a2.

[0026] When using a trolley case:

[0027] The cooperation of the bracket 8, the square plate 2a2 and the cross bar 2a1 can enhance the lateral pressure bearing capacity of the trolley case. When the upper and lower parts of the trolley case are buckled together, the rod body 2a3 is inserted into the groove of the upper square plate 2a2, and then the rod body 2a3 fits with the upper square plate 2a2, thereby improving the pressure bearing capacity of the trolley case in the vertical direction. The wear-resistant pad 13 is nitrile rubber, which has excellent oil resistance, chemical corrosion resistance and wear resistance, thereby avoiding wear when the trolley case is placed horizontally. The ethylene propylene rubber layer 3 has high wear resistance, aging resistance and weather resistance, thereby improving the wear resistance of the trolley case. The waterproof layer 1 4 and the waterproof layer 2 5 are acrylic waterproof coatings, which have excellent waterproof ability, elasticity and ductility, thereby improving the waterproof ability of the trolley case.

[0028] When the wear pad 13 needs to be replaced:

[0029] The screw rod 14 is rotated, and the screw rod 14 drives the insertion rod 15 to move inward, so that the insertion rod 15 is removed from the inner wall of the groove block 11 and the straight block 10, and the wear-resistant pad 13 is moved downward, thereby realizing the disassembly of the wear-resistant pad 13, which is convenient for replacing the wear-resistant pad 13.

[0031] Working principle:

[0032] When the suitcase is moved, the universal wheel 6 is placed on the ground, and the pull rod 7 is pulled to move the suitcase. The provision of the rubber sleeve 2b1 can improve the comfort of the personnel.

[0033] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
