[0024] Now, the present application will be further described in detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, which only illustrate the basic structure of the present application in a schematic manner, so they only show the components related to the present application.

[0025] As Figure 1-7 shown, a double-opening arc-shaped trailer includes a compartment 1 and a towing frame 2. The compartment 1 is arranged on the towing frame 2. A window 10 is provided on the side wall of the compartment 1. A window pane 11 is hinged on the window 10. An arc-shaped sliding sleeve 12 is provided on the inner wall of the compartment 1. An arc-shaped sliding rod 13 is provided on the window pane 11. One end of the arc-shaped sliding rod 13 away from the window pane 11 is slidably arranged in the arc-shaped sliding sleeve 12. A narrow slot 121 is provided on the side wall of the arc-shaped sliding sleeve 12. A shifting rod is provided on the arc-shaped sliding rod 13. The shifting rod passes through the narrow slot 121 and is located outside the arc-shaped sliding sleeve 12. A clamping tooth groove 120 is provided on the arc-shaped sliding sleeve 12. A clamping rod 151 is elastically provided on the shifting rod. The clamping rod 151 is in clamping cooperation with the clamping tooth groove 120 to limit the relative movement between the arc-shaped sliding rod 13 and the arc-shaped sliding sleeve 12.

[0026] The arc-shaped sliding sleeve 12 is arranged at the position where the window plate body 11 is connected to the window 10 in the box body 1, specifically on the inner wall of the box body 1. An arc-shaped sliding cavity is provided inside the arc-shaped sliding sleeve 12, and the sliding cavity is mainly used for the sliding of the arc-shaped sliding rod 13; the slot 121 is preferably opened on the side wall of the lower side of the arc-shaped sliding sleeve 12, and the sliding cavity is communicated with the outside through the slot 121. One end of the toggle rod is fixedly connected to the arc-shaped sliding rod 13.

[0027] When the window plate body 11 is closed, the arc-shaped sliding rod 13 is located in the sliding cavity, and the toggle rod is located at one end of the slot 121 close to the inner wall of the box body 1. When the window plate body 11 is opened, the arc-shaped sliding rod 13 slides out of the outside of the arc-shaped sliding sleeve 12, and the toggle rod is located at one end of the slot 121 close to the inner wall of the box body 1.

[0028] When the clamping tooth groove 120 is clamped with the clamping rod 151, the relative movement between the arc-shaped sliding rod 13 and the arc-shaped sliding sleeve 12 is restricted to realize the hovering of the window plate body 11 at any angle. When it is necessary to close the window 10, control the clamping rod 151 to disengage from the cooperation with the clamping tooth groove 120, and the relative movement of the arc-shaped sliding rod 13 and the arc-shaped sliding sleeve 12 can be restored.

[0029] In this application, the arc-shaped sliding sleeve 12 and the arc-shaped sliding rod 13 are in sliding fit to directly control the opening and closing of the window plate body 11. The structure is simple and the installation accuracy requirement is low; moreover, the arc-shaped sliding rod 13 and the arc-shaped sliding sleeve 12 are in an arc-shaped structure, which can better bear the acting force of the window plate body 11 during the movement process and ensure the service life.

[0030] In some further embodiments, the number of the windows 10 is two, and the two windows 10 are arranged at intervals along the length direction of the box body 1; a through hole 17 is provided at one end of the toggle rod away from the arc-shaped sliding rod 13.

[0031] In this embodiment, a total of two windows 10 are provided, and each window 10 is correspondingly provided with two sets of relative components such as the arc-shaped sliding rod 13 and the arc-shaped sliding sleeve 12.

[0032] The through hole 17 is provided on the toggle rod. In some other embodiments, a rod-like structural component can pass through all the through holes 17 or several of the through holes 17 to jointly realize the opening and closing of the window plate body 11.

[0033] In some further embodiments, the toggle rod includes a telescopic rod 15 and a telescopic sleeve 14. One end of the telescopic rod 15 passes through the slot 121 and is connected to the arc-shaped sliding rod 13, and the other end of the telescopic rod 15 is slidably sleeved in the telescopic sleeve 14; a sliding groove 140 is provided on the telescopic sleeve 14, and a sliding block 150 is provided on the telescopic rod 15. The sliding block 150 is in sliding fit with the sliding groove 140; the through hole 17 is provided at one end of the telescopic sleeve 14 away from the telescopic rod 15.

[0034] In order to make it easier to open and close the window panel 11, the lever has a telescopic function, which is realized by the telescopic rod 15 and the telescopic sleeve 14.

[0035] The sliding of the telescopic sleeve 14 and the telescopic rod 15 is realized by the sliding block 150 and the sliding groove 140. The sliding groove 140 is specifically arranged on the telescopic sleeve 14, has a long and narrow structure, and is communicated with the inside of the telescopic sleeve 14. The sliding block 150 is directly fixed on the outer peripheral wall of the telescopic rod 15. When the telescopic sleeve 14 is sleeved on the telescopic rod 15, the sliding block 150 is located in the sliding groove 140 to ensure the sliding stability of the telescopic rod 15 and the telescopic sleeve 14.

[0036] In addition, the arrangement of the telescopic rod 15 and the telescopic sleeve 14 can also save a certain amount of internal space of the compartment 1, that is, when the window panel 11 does not need to be opened and closed, the telescopic rod 15 can be located in the telescopic sleeve 14.

[0037] In some further embodiments, a limiting plane is provided on the telescopic rod 15, and an abutting bolt 18 is provided on the telescopic sleeve 14 in the radial direction. One end of the abutting bolt 18 located inside the telescopic sleeve 14 is used to abut against the limiting plane.

[0038] In order to ensure the sliding locking of the telescopic rod 15 and the telescopic sleeve 14, an abutting bolt 18 is provided on the telescopic sleeve 14. When the telescopic position is reached, the abutting bolt 18 is tightened, and the telescopic movement between the telescopic rod 15 and the telescopic sleeve 14 can be locked.

[0039] In some further embodiments, a first spring 122 is provided inside the arc-shaped sliding sleeve 12. One end of the first spring 122 abuts against one end of the arc-shaped sliding rod 13, and the other end of the first spring 122 abuts against the end face of the inner part of the arc-shaped sliding sleeve 12 far from the arc-shaped sliding rod 13.

[0040] In order to make it easier to open the window panel 11 and more stable when closing, a first spring 122 is provided inside the arc-shaped sliding sleeve 12, so as to play a certain buffering role for the arc-shaped sliding rod 13.

[0041] It should be noted that the first spring 122 is always in a compressed state.

[0042] In some further embodiments, a chute 152 is radially penetrated through the telescopic rod 15, a clamping rod 151 is arranged in the chute 152, a second spring 153 is arranged in the chute 152, one end of the second spring 153 abuts against the clamping rod 151, and the other end of the second spring 153 abuts against the side wall of the chute 152 far from the arc-shaped sliding rod 13; a clamping tooth groove 120 is arranged on the side wall of the arc-shaped sliding sleeve 12 where the narrow groove 121 is arranged.

[0043] Specifically, under the action of the second spring 153, both ends of the clamping rod 151 are always clamped in the clamping tooth grooves 120.

[0044] In some further embodiments, the clamping tooth groove 120 is a one-way locking groove, that is, one side wall of the clamping tooth groove 120 is inclined and the other side wall is vertical. When opening the window plate body 11, the end of the clamping rod 151 continuously abuts against the inclined side wall in one clamping tooth groove 120 and slides into another clamping tooth groove 120.

[0045] However, since the other side wall is vertical, the movement between the arc-shaped sliding rod 13 and the arc-shaped sliding sleeve 12 can be realized only when the clamping rod 151 is pulled back away from the clamping tooth groove 120.

[0046] In some further embodiments, tires 21 and folding support rods 20 are provided at the bottom of the towing frame 2.

[0047] In some further embodiments, the folding support rod 20 includes a hinge seat 200, a rod body 202, a plugging rod 204, and a third spring 205; the hinge seat 200 is arranged at the bottom of the towing frame 2, the hinge seat 200 includes two side plates arranged at intervals, the top of the rod body 202 is hinged between the two side plates, a turntable 201 is provided at the top of the rod body 202, and a plugging hole is provided on the turntable 201; an installation cavity 203 is provided on one side of one side plate facing away from the other side plate, the plugging rod 204 slides through the installation cavity 203 along the length direction of the hinge axis of the rod body 202, a baffle 206 is provided on the plugging rod 204, the third spring 205 is located in the installation cavity 203 and sleeved on the plugging rod 204, one end of the third spring 205 abuts against the side of the baffle 206 facing away from the hinge seat 200, and the other end of the third spring 205 abuts against the side of the installation cavity 203 facing the hinge seat 200.

[0048] During the movement of the trailer, the folding support rod 20 is horizontally arranged, and only the tires 21 are in contact with the ground.

[0049] When stopped, in order to ensure stability, the folding support rod 20 needs to be folded into a vertical state and locked.

[0050] Specifically, pull the plugging rod 204 away from the hinge seat 200. At this time, the third spring 205 is compressed, the plugging rod 204 is disengaged from the plugging hole on the turntable 201, synchronously rotate the rod body 202 and the turntable 201 to make the rod body 202 vertical. At this time, release the plugging rod 204, and under the action of the third spring 205, the plugging rod 204 is plugged into the plugging hole to realize the anti-rotation locking of the rod body 202.

[0051] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of this application's creation.
