[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] The directional terms mentioned in this utility model, such as "up", "down", "front", "back", "left", "right", "inner", "outer", "side", "top" and "bottom", are only for reference to the orientation of the accompanying drawings. The directional terms used are for the purpose of explaining and understanding this utility model, and are not intended to limit this utility model.
[0026] Example 1:
[0027] like Figures 1-5 As shown, a positioning structure for a detachable carriage and chassis includes a first limiting component disposed on the chassis 1 and a second limiting component disposed on the carriage 2 and capable of cooperating with the first limiting component; the first limiting component includes a first stop 6 and a second stop 7 located at both ends of the chassis 1; the second limiting component includes a first limiting component 8 and a second limiting component 9 located at both ends of the carriage 2; the first stop 6 and the first limiting component 8 cooperate with each other, and the second stop 7 and the second limiting component 9 cooperate with each other.
[0028] The end closer to the front of the car is defined as the front end, and the end closer to the rear of the car is defined as the rear end. Figure 2 As shown, the left side is the backend, and the right side is the frontend.
[0029] The cross-section of the carriage 2 is rectangular, and each of the four corners of the carriage 2 is equipped with a retractable support leg 3, and each support leg 3 is equipped with a roller at its bottom.
[0030] The two rollers at the front of the carriage 2 are omnidirectional wheels 4 that can rotate horizontally, and the two rollers at the rear of the carriage 2 are fixed wheels 5 that can only roll in the left and right directions of the carriage 2.
[0031] The first stop 6 is cylindrical or has a groove formed on one side; cylindrical, such as Figure 3 Number 6, with a groove constructed on one side as shownFigure 3 Number 7 in the text refers to a shape with a groove on one side. The original shape is a cuboid or cube, with a groove created on one side, such as... Figure 3 The V-shape in the middle is formed into an arc at the bend.
[0032] The second stop 7 is cylindrical or has a groove formed on one side.
[0033] The first limiting member 8 is cylindrical or has a groove formed on one side, such as a cylindrical shape. Figure 5 Number 9 in the diagram, with a groove constructed on one side, is like... Figure 4 Number 8 in the text.
[0034] The second limiting member 9 is cylindrical or has a groove formed on one side.
[0035] When the first stop 6, the second stop 7, the first limiter 8, or the second limiter 9 are cylindrical, a sleeve 10 is fitted on their outer side, which can offset the impact, reduce the gap between the first limiter assembly and the second limiter assembly, and prevent shaking.
[0036] When the first stop 6, the second stop 7, the first limiting member 8, or the second limiting member 9 is formed into a groove shape on one side, the one located at the front end of the carriage 1 forms a groove on its front side, and the one located at the rear end of the carriage 1 forms a groove on its rear side.
[0037] When the first limiting member 8 or the second limiting member 9 is cylindrical, it is rotatably disposed on the outside of the carriage 1; it is provided with a limiting component, which rotates to the horizontal when not in use and is restricted to the horizontal state.
[0038] When the first limiting member 8 or the second limiting member 9 is cylindrical, it is detachably disposed on the outside of the carriage 1.
[0039] When the first limiting member 8 or the second limiting member 9 is cylindrical, its connection position with the carriage 1 is located above the first limiting member 8 or the second limiting member 9. When the carriage 1 is completely placed on the chassis, the connection position of the first limiting member 8 or the second limiting member 9 with the carriage 1 is higher than the top of the first limiting component, preventing the first limiting component from abutting against the second limiting component.
[0040] By setting mutually cooperating limiting components at both the front and rear ends of the carriage and the chassis, the carriage is restricted to the chassis. This ensures that the corresponding cylindrical first limiting component cooperates with the grooved second limiting component, or that the corresponding grooved first limiting component cooperates with the cylindrical second limiting component. This achieves the positioning of the carriage and the chassis, making the operation convenient, fast, simple in structure, and low in cost. Simply raise the carriage 1 with the lifting outriggers 3, then drive the chassis 1 under the carriage 1, and then lower the carriage.
[0041] The setting of the support leg 3 adopts the existing setting, which has the same setting mode as that in the patent previously applied by the applicant, such as the Chinese utility model patent with the document number CN220662364U and the name of a ground loading and unloading structure of a freight vehicle, or such as the Chinese utility model patent with the document number CN220865392U and the name of a ground support leg of a van freight vehicle. Both of the two schemes have a common point that the support leg is pushed horizontally away when used, so that the support leg is located on the left and right sides of the chassis 1, thereby facilitating the falling of the van compartment 2.
[0042] As shown in Figure 2 , Figure 3 , Figure 4 and Figure 5 , in the embodiment, the first stop piece 6 is cylindrical, the second stop piece 7 is a shape with a groove on one side, the first limiting piece 8 is a shape with a groove on one side, and the second limiting piece 9 is cylindrical. When matched, the groove of the first limiting piece corresponds to the first stop piece 6 when the van compartment 1 is lowered, the first stop piece enters the groove, and the second limiting piece 9 falls into the groove of the second stop piece 7.
[0043] Embodiment 2:
[0044] Different from embodiment one, in the embodiment, the first stop piece 6 is a shape with a groove on one side, the second stop piece 7 is cylindrical, the first limiting piece 8 is cylindrical, and the second limiting piece 9 is a shape with a groove on one side.
[0045] Embodiment 3:
[0046] Different from embodiment one, in the embodiment, the first stop piece 6 is cylindrical, the second stop piece 7 is cylindrical, the first limiting piece 8 is a shape with a groove on one side, and the second limiting piece 9 is a shape with a groove on one side.
[0047] Embodiment 4:
[0048] Different from embodiment one, in the embodiment, the first stop piece 6 is a shape with a groove on one side, the second stop piece 7 is a shape with a groove on one side, the first limiting piece 8 is cylindrical, and the second limiting piece 9 is cylindrical.
[0049] The above description is only used to illustrate the technical scheme of the utility model and is not limited. Other modifications or equivalent replacements of the technical scheme of the utility model made by those skilled in the art should be covered in the scope of the claims of the utility model, as long as they do not deviate from the spirit and scope of the technical scheme of the utility model.
