[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1-3 As shown, this embodiment provides a luggage box fixing device for urban public transportation, including a plurality of vehicle body bearing structures 1 and a sliding trolley 5 arranged on the side wall of the urban public transportation vehicle.

[0029] Specifically, Figure 2 As shown, the vehicle body bearing structure 1 includes a vehicle body fixing slot 2, a vehicle body bottom frame slide slot 3 and a baffle 4, wherein the vehicle body fixing slot 2 is evenly distributed on the upper part of the vehicle body bearing structure 1; the vehicle body bottom frame slide slot 3 is arranged at the bottom of the vehicle body bearing structure 1; and the baffle 4 is located on both sides of the vehicle body bearing structure 1.

[0030] like Figure 3As shown, the sliding trolley 5 includes a U-shaped fixing rod 10, a square clamp 6, a vehicle body frame 7, a cylindrical button 1 8, a cylindrical button 2 9, a buckle 12, a buckle 2 13, a guide rail, a spring 14, a spring 2 15, a spring 3 16 and a square frame 18. The U-shaped fixing rod 10 is arranged at the front end of the sliding trolley 5. The left rod of the U-shaped fixing rod 10 is a telescopic rod mechanism, which is composed of a rod 1 102 and a rod 2 103. The rod 1 102 is nested in the rod 2 103, so as to realize the front and rear telescopic extension of the U-shaped fixing rod 10; the square clamp 6 is symmetrically arranged at the upper rear end of the sliding trolley 5; the vehicle body frame 7 is located at the rear end bottom of the sliding trolley 5, and it moves left and right in the vehicle body frame slide groove 3 of the vehicle body bearing structure 1; the cylindrical button 1 8 is located between the two square clamps 6 on the upper part of the sliding trolley 5, and is used to control the sliding trolley 5 to move left and right in the vehicle body bearing structure 1; the cylindrical button 2 9 is located at the The right end is used to control the forward and backward extension of the U-shaped fixing rod 10; the buckle 12 and the buckle 2 13 are located in the middle of the sliding trolley 5 body, fixing the U-shaped fixing rod 10 at different positions in the front and rear directions; the guide rail 1 11, the guide rail 2 111, the guide rail 3 112, and the guide rail 4 113 are located in the middle of the sliding trolley 5 body, and the U-shaped fixing rod 10 realizes parallel movement in the left and right directions through the guide rail 1 11, the guide rail 2 111, the guide rail 3 112, and the guide rail 4 113; the spring 14 is located between the sliding trolley 5 body and the body chassis 7, and the spring 2 15 is set on the left side of the U-shaped fixing rod 10; the spring 3 16 is located at the rear end of the left rod of the U-shaped fixing rod 10.

[0031] In the embodiment of the present invention, the body bearing structure 1 is made of stainless steel, and the edges and corners can be polished to prevent scratching passengers. The body fixing slot 2 is a square structure, which matches the structure of the square clamp 6 at the upper rear end of the sliding trolley 5. The square clamp 6 is embedded in the body fixing slot 2 to fix the position of the sliding trolley 5 and prevent it from moving left and right.

[0032] In the embodiment of the present invention, the vehicle body frame slide groove 3 is a long square structure, and the vehicle body frame 7 of the sliding trolley 5 is also a square structure. The vehicle body frame 7 moves left and right in the vehicle body frame slide groove 3, and there is no distance between the bottom surface of the vehicle body frame 7 and the bottom surface of the vehicle body frame slide groove 3, ensuring that when the cylindrical button 8 is pressed, the position of the vehicle body frame 7 remains unchanged, so that the square clamp 6 of the sliding trolley 5 is separated from the vehicle body fixed clamp groove 2 by squeezing the spring 14, and then the sliding trolley 5 moves left and right in the vehicle body frame slide groove 3.

[0033] In the embodiment of the present invention, in order to prevent the sliding trolley 5 from sliding out of the slideway of the vehicle body bearing structure 1 , baffles 4 are respectively arranged on both sides of the vehicle body bearing structure 1 , and the material thereof can be the same as that of the vehicle body bearing structure 1 .

[0034] In order to enable the U-shaped fixing rod to move in the left and right directions, thereby disengaging the U-shaped fixing rod from the buckle, in an embodiment of the present invention, the U-shaped fixing rod 10 is located in a square frame 18 in the middle of the body of the sliding trolley 5, and the guide rail 1 11, the guide rail 2 111, the guide rail 3 112, and the guide rail 4 113 are located in the middle of the body of the sliding trolley 5. The U-shaped fixing rod 10 achieves parallel movement in the left and right directions through the guide rails 1 11, the guide rail 2 111, the guide rail 3 112, and the guide rail 4 113. At the same time, a strip groove structure of a corresponding shape is also provided at the joint between the square frame 18 in the middle of the body of the sliding trolley 5 and the guide rails 1 11, the guide rail 2 111, the guide rail 3 112, and the guide rail 4 113, thereby providing guidance for the left and right movement of the sliding trolley 5.

[0035] Furthermore, the left rod of the U-shaped fixing rod 10 is a telescopic rod mechanism, which can be made of stainless steel to ensure its sturdiness. The front curved portion of the U-shaped fixing rod, i.e. the luggage case pull rod portion, can be a shock absorbing strip made of TPE material, which effectively buffers the relative force between the U-shaped fixing rod 10 and the luggage case pull rod 17, thereby preventing the luggage case pull rod 17 from being damaged.

[0036] In the embodiment of the present invention, the vehicle frame 7 is connected to the spring 14. When the cylindrical button 8 is pressed downward, the spring 14 is squeezed, the sliding trolley 5 moves downward as a whole, and the square clamp 6 of the sliding trolley 5 is disengaged from the vehicle body fixed slot 2 of the vehicle body bearing structure 1, so that the sliding trolley 5 moves left and right in the vehicle frame slide slot 3 and slides to a position suitable for the suitcase pull rod 17.

[0037] In the embodiment of the present invention, the function of the buckle 12 and the buckle 2 13 is to fix the U-shaped fixing rod 10 at different positions in the front-to-back direction. The buckle 12, the buckle 2 13 and the position where the hook 101 of the U-shaped fixing rod 10 is buckled with the buckle are all arc-shaped. The buckle 12 and the buckle 2 13 can both be made of rigid stainless steel with a smooth surface to prevent the position where the end of the U-shaped fixing rod 10 is buckled with the buckle from being worn. When the luggage case pull rod 17 is placed in the front end curved part of the U-shaped fixing rod 10, the U-shaped fixing rod 10 is pushed backwards, and when the position where the hook 101 of the U-shaped fixing rod 10 is locked with the buckle contacts the buckle, the U-shaped fixing rod 10 is pushed backwards with a little force, and the two arc surfaces are squeezed. Since the front end curved part of the U-shaped fixing rod 10, that is, the part that locks the luggage case pull rod 17, is made of TPE material, it can be slightly deformed, so that the position where the hook 101 of the U-shaped fixing rod 10 is locked with the buckle passes over the arc end of the buckle 12, and at this time, the spring three 16 at the rear end of the telescopic rod mechanism of the U-shaped fixing rod 10 is squeezed and has a forward rebound force, thereby ensuring that the position where the hook 101 of the U-shaped fixing rod 10 is locked with the buckle is locked with the buckle 12, thereby fixing the luggage case.

[0038] In the embodiment of the present invention, the second spring 15 is located on the left side of the U-shaped fixing rod 10, and its function is to make the non-working U-shaped fixing rod 10 break away from the fixation of the second buckle 13 and rebound to its original position relative to the left and right directions; the third spring 16 is located at the rear end of the telescopic rod mechanism of the U-shaped fixing rod 10, and it realizes the function of popping forward when the U-shaped fixing rod 10 breaks away from the fixation of the first buckle 12 or the second buckle 13.

[0039] The working process and working principle of the urban public transportation luggage box fixing device of the present invention are as follows:

[0040] When the luggage fixing device is not working, the U-shaped fixing rod 10 is buckled with the second buckle 13; when the luggage fixing device is used, the cylindrical button 18 is pressed, and the sliding trolley 5 can move left and right. After moving it to a suitable position, the cylindrical button 18 is released to fix the position of the sliding trolley 5. The cylindrical button 29 is pressed, and the U-shaped fixing rod 10 is released from the buckle 2 13 and pops forward. After the luggage pull rod 17 is placed in the front curved part of the U-shaped fixing rod 10, the U-shaped fixing rod 10 is pushed backward so that the position where the end 101 of the U-shaped fixing rod 10 is buckled with the buckle 12 is buckled, thereby fixing the luggage; when the luggage is to be taken out, the cylindrical button 29, which is partially fixed in the square frame 18, is pressed, and the U-shaped fixing rod 10 pops forward, and the luggage pull rod 17 is taken out of the U-shaped fixing rod 10, and the U-shaped fixing rod 10 is pushed backward so that it is buckled with the second buckle 13.
