[0002] A luggage trolley is a mode of transport for cargo and mail, which is fast and maneuverable. In air transport, luggage trolleys are often used to transport luggage.

[0003] There are many kinds of airport luggage trailers on the market, but generally they cannot absorb shock and make loud noises. After the luggage is placed on the trailer, it cannot be effectively fixed, and the luggage will shake during the towing process, causing loud noises. Moreover, when dragging the luggage, different users cannot adjust the height of the pulling point according to their appropriate height. When users who are too tall or too short use the luggage, they will bend over or cannot reach the luggage, which will cause inconvenience to the users. For this reason, we propose a shock-absorbing platform for luggage trailers. Utility Model Content

[0025] See also Figure 1-4 A shock-absorbing platform for a luggage trailer comprises a bottom plate 1, connecting plates 2 are fixedly installed around the top of the bottom plate 1, columns 3 are arranged on the top of the connecting plates 2, springs 4 are set on the outer rings of the columns 3, mounting seats 5 are arranged on the tops of the columns 3, circular grooves 6 are opened on the bottoms of the mounting seats 5, platforms 7 are arranged on the tops of the four mounting seats 5, first protective pads 8 are fixedly installed on both sides of the inner wall of the platform 7, a supporting plate 13 is fixedly installed on the left side of the bottom plate 1, two hydraulic telescopic rods 14 are arranged on the top of the supporting plate 13, a mounting plate 15 is arranged on the top of the output ends of the two hydraulic telescopic rods 14, a square plate 16 is fixedly installed on the top of the mounting plate 15, and two vertical rods 19 are fixedly installed on the top of the square plate 16.

[0026] Furthermore, electric telescopic rods 9 are provided on the front and back of the platform 7, and second protective pads 10 are provided on one side of the output ends of the two electric telescopic rods 9. Advantages: the two second protective pads 10 are driven by the output ends of the two electric telescopic rods 9 to move to the front and back positions of the luggage, and the distance between the two second protective pads 10 is adjusted according to the overall luggage, so as to fix the luggage to prevent the luggage from shaking during the movement; at the same time, the luggage can be protected by the two first protective pads 8 and the two second protective pads 10 to prevent the luggage from colliding with the platform 7, thereby having the effect of protecting the luggage.

[0027] Furthermore, two shock-absorbing pads 11 are fixedly installed between the bottom of the platform 7 and the top of the base plate 1, and dampers 12 are fixedly installed on the tops of the two shock-absorbing pads 11. Advantages: when the luggage in the platform 7 shakes, the mounting seat 5 can be moved downward on the column 3 through the circular groove 6, and the spring 4 on the outer circle of the column 3 is pressed when moving downward. When pressing, part of the force can be offset by the extension ability of the spring 4 itself, and it can also be reset at the same time. The shaking generated when the spring 4 is pressed down or reset can be offset and reduced by the damper 12 and the shock-absorbing pad 11, preventing the spring 4 from being pressed down and reset with an amplitude too large to be able to absorb shock, so that shock absorption and buffering can be performed when the luggage is checked in to prevent the generation of large noise.

[0028] Furthermore, the top and bottom of the two hydraulic telescopic rods 14 are fixedly connected to the bottom of the mounting plate 15 and the top of the support plate 13 respectively, with the advantage that the output ends of the two hydraulic telescopic rods 14 can drive the mounting plate 15 and the two vertical poles 19 thereon to move up and down, making it convenient for different users to adjust the two vertical poles 19 to a suitable position according to their own heights, thereby preventing users who are too tall or too short from bending over or unable to reach the device when using it, thereby improving the applicability of the device when in use.

[0029] Furthermore, thread grooves 17 are formed on both sides of the top of the mounting plate 15 and the square plate 16, and the inner cavities of each two thread grooves 17 are threadedly connected with fixing bolts 18. Advantages: by rotating the two fixing bolts 18 clockwise in the inner cavities of two groups of thread grooves 17 to a position where they cannot be rotated, the square plate 16 and the mounting plate 15 are fixed, and the two vertical poles 19 are stabilized, thereby preventing the two vertical poles 19 from shaking and being unstable when the device is used, thereby preventing the adverse phenomenon of affecting normal use.

[0030] Furthermore, a handle 20 is fixedly mounted on the top of the two upright poles 19 , a protective ring 21 is sleeved on the middle of the handle 20 , and universal wheels 22 are arranged around the bottom of the base plate 1 .

[0031] Furthermore, the material of the protective ring 21 is rubber, and the universal wheels 22 are all self-locking universal wheels, which have the advantages that by holding the handle 20, the four universal wheels 22 around the bottom of the base plate 1 can be driven to rotate to move the device and check in the luggage. At the same time, when holding the handle 20, the protective ring 21 made of rubber can be used to protect the user's hands to prevent discomfort caused by long-term friction with the user's hands, and the four universal wheels 22 are self-locking universal wheels, which can lock the universal wheels 22 when the luggage is placed on the platform 7 to prevent autonomous movement.

[0032] Working principle: When in use, first place the luggage on the platform 7. After placing the luggage, the two second protection pads 10 can be driven to move to the front and back positions of the luggage through the output ends of the two electric telescopic rods 9. The distance between the two second protection pads 10 is adjusted according to the overall luggage to fix the luggage to prevent it from shaking during the movement. At the same time, the luggage can be protected by the two first protection pads 8 and the two second protection pads 10 to prevent the luggage from colliding with the platform 7, thereby having the effect of protecting the luggage. At this time, the user can drive the mounting plate 15 and the two vertical poles 19 thereon to move up and down through the output ends of the two hydraulic telescopic rods 14, which can facilitate different users to adjust the two vertical poles 19 to a suitable position according to their own height, thereby preventing users who are too high or too low from bending over and not being able to reach the device when using it, thereby improving the applicability of the device when in use. After adjusting to a suitable position, the user can drive the mounting plate 15 and the two vertical poles 19 thereon by holding the provided handle 20. The four universal wheels 22 around the bottom of the base plate 1 rotate to move the device to check in the luggage. At the same time, when holding the handle 20, the protective ring 21 made of rubber material can be used to protect the user's hands to prevent long-term friction with the user's hands from causing discomfort. When checking in the luggage, when the luggage in the platform 7 shakes, the mounting seat 5 can be moved down on the column 3 through the circular groove 6. When moving down, the spring 4 on the outer ring of the column 3 is pressed. When pressing, the extension capacity of the spring 4 itself can offset part of the force, and it can also be reset. The shaking generated when the spring 4 is pressed down or reset can be offset and slowed down by the damper 12 and the shock-absorbing pad 11 to prevent the spring 4 from being pressed down and reset too much and unable to be shock-absorbing. Therefore, it can be shock-absorbing and buffered when the luggage is checked in to prevent large noise. The four universal wheels 22 are set with a self-locking function. When the luggage is placed in the platform 7, the universal wheels 22 can be locked to prevent autonomous movement.
