One side of the guide frame 11 is bent toward the vehicle body shell 101, and the guide frame 2 111 is located on the side away from the guide frame 110 and is bent toward the vehicle body shell 101; wherein, the guide frame 110 is provided with a movable groove 112 on the inner side of the bending part; wherein, the bottom surface of the mounting plate 109 is rotatably connected to a rotating shaft 113 near the movable groove 112, and one end of the side of the rotating shaft 113 is fixedly connected to a push rod 114, the surface of the push rod 114 is slidably connected to the movable groove 112, and the push rod 114 is located at the end away from the rotating shaft 113 and extends to the inside of the guide frame 110, as shown in FIG. Figures 1-2 As shown, the length directions of the guide frame 1 10 and the guide frame 2 111 are consistent, and the bending parts of the guide frame 1 10 and the guide frame 2 111 are to guide the door body 201 to be staggered with the door opening 102, so that the subsequent door body 201 can continue to slide.
[0029] A return torsion spring 115 is fixedly connected to the bottom surface of the mounting plate 109 and located outside the rotating shaft 113. The other end of the return torsion spring 115 is fixedly connected to the side of the rotating shaft 113. Figure 3 As shown, the return torsion spring 115 drives the rotating shaft 113 to rotate, so that the push rod 114 rotates in the counterclockwise direction;
[0030] The compartment door 2 includes a door body 201, one side of the top surface of the door body 201 is fixedly connected to an extension plate 1 202, and the other side of the top surface of the door body 201 is fixedly connected to an extension plate 203. The tops of the extension plates 1 202 and 203 are both rotatably connected to guide wheels 204. Figure 1 、 Figure 4 As shown, the two guide wheels 204 move along the guide frame 1 10 and the guide frame 2 111 respectively;
[0031] The two guide wheels 204 are respectively connected to the inner side of the guide frame 1 10 and the guide frame 2 111 in a sliding manner, and the guide wheel 204 located on the inner side of the guide frame 1 10 abuts against the side of the push rod 114. Figure 1 、 Figure 3 As shown, the push rod 114 moves the door body 201 by pushing the guide wheel 204;
[0032] One side of the door main body 201 away from the second extension plate 203 is fixedly connected with a third extension plate 205. The bottom of the third extension plate 205 is fixedly connected with a resisting shaft 206. Both sides of the outer wall of the door main body 201 are movably connected with the inner side of the door opening 102. One inner end of the door opening 102 is fixedly connected with a connecting piece 104. One side of the connecting piece 104 close to the third extension plate 205 is fixedly connected with a limiting sleeve 103. The inner wall of the limiting sleeve 103 is slidably connected with a resisting block 105. One end of the resisting block 105 extends to the outside of the limiting sleeve 103. The middle part of the other end of the resisting block 105 is fixedly connected with an operating rope 107. A spring 106 is fixedly connected to the surface of the resisting block 105 and outside the operating rope 107. The other side of the spring 106 is fixedly connected with the inner wall of the limiting sleeve 103. As Figure 5 shown, the spring 106 pushes the resisting block 105 to extend to the left;
[0033] One end of the resisting block 105 located outside the limiting sleeve 103 is provided with an inclined surface. The side of the resisting block 105 abuts against the resisting shaft 206. One end of the operating rope 107 extends to the outside of the limiting sleeve 103, and the surface of the operating rope 107 is movably connected with the inner wall of the vehicle body shell 101. As Figures 1-5 shown, the operating rope 107 is a steel wire rope. According to the control system inside the van-type vehicle, the operating rope 107 is connected to the handle or knob inside the carriage.
[0034] The working principle of the present utility model:
[0035] When the door is opened, the operating rope 107 is pulled by the control system inside the carriage, driving the resisting block 105 to compress the spring 106 and contract into the inside of the limiting sleeve 103, so that the resisting shaft 206 is separated from the resisting block 105, and the movement of the door main body 201 is not blocked. Since the reset torsion spring 115 is in a stretched state when the door main body 201 is closed inside the door opening 102, after the resisting shaft 206 is separated from the resisting block 105, the reset torsion spring 115 pushes the rotating shaft 113 to rotate, and the push rod 114 pushes the guide wheel 204 inside the first guide frame 110 to move out of the bent area inside the first guide frame 110. At this time, the door main body 201 is simultaneously pushed to move along the direction of the first guide frame 110;
[0036] When the door body 201 is closed, if the door body 201 is pushed into place, the axle 206 pushes the inclined side of the block 105, and the block 105 shrinks into the inner part of the limiting sleeve 103. When the block 105 and the axle 206 are staggered, the door body 201 is completely stuck in the inner side of the door 102. At this time, the spring 106 pushes the block 105 to extend out of the limiting sleeve 103 again, so that the block 105 directly blocks the movement of the axle 206, and then the door body 201 is closed. 01 is fixed. If the door body 201 fails to close in place, not only the block 105 cannot block the shaft 206, but also the return torsion spring 115 pushes the rotating shaft 113 to rotate, so that the push rod 114 pushes the guide wheel 204 inside the guide frame 110, so that the door body 201 moves along the guide frame 110 in the direction away from the door body 201, and thus the door body 201 cannot maintain the half-closed state, which makes it convenient for the operator to observe with the naked eye whether the door is closed in place.
[0037] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
