Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0013] like Figures 1-3 As shown, an adjustable-width trailer includes a left body 1, a right body 2, and a connector; The left vehicle body 1 includes a first connecting plate 11, a wheel 12, and a frame body 13; the first connecting plate 11 is located on the right side of the frame body 13 and is used to connect to the connecting parts; the wheel 12 is located on the left side of the frame body 13. The right vehicle body 2 has the same structure as the left vehicle body 1 and is symmetrically arranged on the right side of the connecting piece; The connector includes a sliding connecting seat 31, a second connecting plate 32, a first connecting beam 33, and a connecting shaft 34. The top wall of the second connecting plate 32 is provided with multiple fixing holes 35. The sliding connecting seat 31 is fitted onto the second connecting plate 32, and the top wall of the sliding connecting seat 31 is provided with connecting holes 38 that match the fixing holes 35. Vertical connecting shafts 34 are hinged to both the left and right sides of the sliding connecting seat 31. The first connecting plate 11 of the left vehicle body 1 and the right vehicle body 2 is provided with a first mounting seat 36, and the first mounting seat 36 is also provided with a connecting shaft 34. One end of the first connecting beam 33 is hinged to the connecting shaft 34 of the sliding connecting seat 31, and the other end is hinged to the connecting shaft 34 of the first connecting plate 11 of the left vehicle body 1 or the right vehicle body 2. The first connecting plate 11 is provided with a first mounting seat 36, and the first mounting seat 36 is provided with a vertical connecting shaft 34. The left and right sides of the second connecting plate 32 are provided with a plurality of second mounting seats 37 that match the first connecting plate 11. The second mounting seats 37 are also provided with vertical connecting shafts 34. A second connecting beam 39 is provided between the first mounting seat 36 and the second mounting seat 37. One end of the second connecting beam 39 is hinged to the connecting shaft 34 of the first mounting seat 36, and the other end is hinged to the connecting shaft 34 of the second mounting seat 37. The first connecting beam 33, the second connecting beam 39, the second connecting plate, and the first connecting plate 11 form an isosceles trapezoidal structure.

[0014] When using this device, first place the left vehicle body 1 and the right vehicle body 2 on the left and right sides respectively. Place the connector between the left vehicle body 1 and the right vehicle body 2. The second connecting plate 32 serves as the mounting base. The sliding connecting seat 31 is fitted onto the second connecting plate 32. Vertical connecting shafts 34 are provided on both the left and right sides of the sliding connecting seat 31 as the connection base. The first connecting plate 11 of both the left vehicle body 1 and the right vehicle body 2 is also provided with a first mounting seat 36. The first mounting seat 36 is also provided with a vertical connecting shaft 34, so that the first connecting beam 33 serves as the main connector. The left and right ends are connected to the connecting shafts 34 on the first mounting seat 36 or the sliding connecting seat 31 respectively, connecting the left vehicle body 1 and the right vehicle body 2. When it is necessary to adjust the width of the vehicle body, move the sliding connecting seat 31 along the length of the second connecting plate 32. Since both ends of the first connecting beam 33 are hinged, both ends of the first connecting beam 33 can rotate during the sliding of the sliding connecting seat 31. When the first connecting beam 33 moves from an inclined state to a horizontal state, the distance of the vehicle body increases, and vice versa. After sliding a certain distance and the width of the vehicle body is appropriate, align the connecting hole 38 of the sliding connecting seat 31 with the fixing hole 35 on the second connecting plate 32, and then use bolts to insert and fix it, thereby improving the stability of the device. The wider vehicle body can accommodate more goods. When it is necessary to narrow the vehicle body, remove the bolts and move the sliding connecting seat 31 in the opposite direction to adapt to narrower transportation roads and improve the applicability of the device.

[0015] To increase the stability of the device connection, a first mounting seat 36 is added to the first connecting plate 11. The first mounting seat 36 and the sliding connecting seat 31 have the same function, both serving as the mounting base. The first mounting seat 36 also has the same connecting shaft 34. Correspondingly, a second mounting seat 37 is provided on the second connecting plate 32. The second mounting seat 37 has the same structure as the first mounting seat 36 and corresponds to it, both using the connecting shaft 34 as the mounting base for the second connecting beam 39. At this time, both the left vehicle body 1 and the right vehicle body 2 have connecting shafts 34 on the first connecting plate 11, and connecting shafts 34 are also provided on the left and right sides of the second connecting plate 32. The first connecting beam 33 and the second connecting beam 39 are used for connection. During the adjustment of the vehicle body width, since both ends of the first connecting beam 33 and the second connecting beam 39 are hinged to the connecting shaft 34, the first connecting beam 33 rotates along with the sliding connecting seat 31 when it slides, preventing motion interference. After the sliding connecting seat 31 is fixed, the first connecting beam 33, the second connecting beam 39, the second connecting plate 32 and the first connecting plate 11 form an isosceles trapezoidal structure. The lengths of the first connecting beam 33 and the second connecting beam 39 are equal, and the first connecting plate 11 and the second connecting plate 32 always remain parallel. Under this state, the vehicle body can ensure normal operation and will not become wider or narrower during movement.

[0016] As a further technical solution to the above scheme, multiple copies of the first mounting base 36, the second mounting base 37, and the second connecting beam 39 are provided. In this embodiment, the first mounting base 36, the second mounting base 37, and the second connecting beam 39 are configured as a group, and multiple groups are provided, which increases the connection stability of the device.
