In addition, the technical features involved in different embodiments of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] In the description of the utility model, it needs to be explained that the orientation or position relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like is the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0027] In the description of the utility model, it needs to be explained that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be a locking connection, or it can be a detachable connection, or it can be integrally connected; it can be mechanical connection, or it can be electrical connection; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication inside two elements. For the person skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0028] As shown in Figure 1 , Figure 2 The embodiment of the utility model provides a rail loading and unloading box for vehicle, including box body 1, rail assembly, first limiting assembly and second limiting assembly. Among them, the box body 1 is used to load and unload goods, and it is detachably connected with the rail assembly. The rail assembly is arranged in the carriage (of course, it can also be arranged in the warehouse of other transport tools), and the first limiting assembly and the second limiting assembly are movably connected or detachably connected with the rail assembly, so that the box body 1 is limited by the first limiting assembly and the second limiting assembly after being installed on the rail assembly, the shaking amplitude of the box body 1 in the carriage is reduced, and the transportation stability is improved.

[0029] At the same time as Figure 3As shown, the track assembly comprises at least two guide rails 2 arranged in parallel, which are used to support and guide the bottom of the box 1, so that the box 1 can move along the guide rails 2. The guide rails 2 are provided with guide grooves 3, and the guide grooves 3 are provided with notches 4. Correspondingly, the bottom of the box 1 is provided with connecting pieces 5 matched with the guide grooves 3 and the notches 4. The maximum width of the connecting piece 5 is smaller than the width of the guide groove 3 and larger than the width of the notch 4, and the minimum width of the connecting piece 5 is smaller than the width of the notch 4. Therefore, when the connecting piece 5 is inserted into the guide groove 3, the connecting piece 5 is limited by the notch 4 and cannot be removed from the notch 4, that is, the up-down movement of the box 1 is limited, and the transverse movement of the box 1 is also automatically limited by the guide groove 3. Subsequently, the longitudinal movement of the box 1 is limited by the first limiting assembly or the second limiting assembly, so as to ensure the stable installation of the box 1.

[0030] As shown in the drawings, Figure 4 As a preferred embodiment, in the embodiment, the connecting piece 5 is arranged as an I-beam, the width of the flange of the I-beam is larger than the width of the notch 4, and the thickness of the web is smaller than the width of the notch 4. Therefore, the above-mentioned size requirements can be well met, and the I-beam itself is a standard profile, so the manufacturing is relatively convenient. The I-beam is welded and fixed to the bottom of the box 1.

[0031] As a preferred embodiment, in the embodiment, a plurality of supporting rollers 6 are densely arranged in the guide groove 3 along the direction of the guide rail 2. The supporting roller 6 is freely rotatably connected with the guide rail 2. When the connecting piece 5 enters the guide groove 3, the box 1 can be conveniently moved by relying on the rolling support of the supporting roller 6, and the box 1 is convenient to be loaded and unloaded by manual or machine.

[0032] It should be noted that, in the embodiment, the guide groove 3 is arranged in a trumpet shape at the position of the notch 4 close to the end (the entrance and exit are integrated), that is, the width of the notch 4 gradually decreases from the end to a preset value and then remains unchanged, so as to conveniently guide the movement of the box 1 and avoid the alignment difficulty in the process of the box 1 entering the guide groove 3 at the initial stage, especially in the case that the box 1 is loaded with heavy objects.

[0033] In the embodiment, the first limiting assembly comprises a limiting pin 7, and a pin hole is formed in the guide rail 2. The limiting pin 7 can be inserted into the pin hole and partially extend above the guide rail 2, so as to limit the box 1 and prevent the box 1 from moving longitudinally after being moved to a position, thereby reducing the front-back shaking amplitude of the box 1 when the carriage accelerates or decelerates. As a preferred embodiment, in the embodiment, the limiting pin 7 is arranged in a door shape, and the two ends of the limiting pin 7 are movably inserted into the pin holes, so as to facilitate manual and rapid installation and disassembly by using the movable connection mode.

[0034] In the embodiment, the second limiting assembly comprises a limiting block 8 and a limiting seat 9, and multiple sets are arranged. The limiting seat 9 is fixedly connected with a mounting frame 10 of the carriage or the fixed guide rail 2, the limiting block 8 is hinged with the limiting seat 9, and has a certain rotary damping force. When the limiting block 8 rotates to the outside, the limiting block 8 does not act on the box body 1, at this time, the box body 1 can move along the guide rail 2 smoothly. When the box body 1 is in place and is longitudinally limited by the limiting pin 7, the limiting block 8 can be rotated to the inside, at this time, the limiting block 8 can limit the box body 1 in the transverse direction, to avoid the transverse shaking of the box body 1. It can be understood that, since the width of the guide groove 3 is slightly larger than the width of the I-beam wing plate (such arrangement is necessary to avoid the pushing and pulling of the box body 1 being blocked), the box body 1 can be more stable in the transverse direction through the limiting block 8.

[0035] In addition, the mounting frame 10 can further be provided with a detachable cross bar 11, the cross bar 11 is connected with the mounting frame 10 through the mounting pin at the end of the cross bar 11 and the mounting hole on the mounting frame 10, so that after the box body 1 is installed in place and limited, the cross bar 11 further separates the box body 1, and limits the longitudinal movement of the box body 1 at a higher position, to further improve the limiting reliability.

[0036] As described above, through the arrangement of the first limiting assembly and the second limiting assembly, the box body 1 can be longitudinally and transversely limited after being moved in place, so as to avoid the shaking of the box body 1 caused by the movement of the vehicle or other transportation tools, to ensure the safety and reliability of the goods transportation in the box body 1. The device can be applied to multiple transportation tools, and of course can also be applied to fixed places such as factories and wharfs, to improve the use flexibility.

[0037] The technical features of the above embodiments can be combined arbitrarily, in order to make the description simple, not all possible combinations of the technical features in the above embodiments are described, however, as long as the combinations of the technical features do not exist contradictory, it should be considered that it is within the scope of the present application.

[0038] The above embodiments only express several implementation manners of the present application, the description is more specific and detailed, but it should not be understood as the limitation of the scope of the application. It should be pointed out that, for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
