Detailed Description
The present invention will be further described with reference to the following specific embodiments.
As shown in fig. 1, in actual use, the anti-dropping structure for the external sliding door is installed on a door leaf 1, and is respectively connected with a door frame 2, a bearing mechanism 3 and a driving mechanism 4 installed at an entrance of a vehicle body to drive the door leaf 1 to open or close.
An anti-drop structure for an externally hung sliding door, comprising: the device comprises a door leaf 1, wherein one side of the top of the door leaf 1 is connected with a first mounting frame 5, a travelling wheel 6 is arranged on the first mounting frame 5, and the travelling wheel 6 is movably connected with a guide rail groove 301 on one side of a bearing mechanism 3; the other side of the top of the door leaf 1 is connected with a hinged plate 7, an anti-falling roller 8 is arranged on the hinged plate 7, and a gap is arranged between the anti-falling roller 8 and a pressing strip 201 on the top of the door frame 2.
The anti-drop roller 8 includes: the bearing 801 is sleeved on the mounting hole 701 of the hinge plate 7, an eccentric shaft 802 is rotatably connected in the bearing 801, a roller 803 is arranged at the top of the eccentric shaft 802, and a nut 804 is connected at the bottom of the eccentric shaft 802.
The free end of the hinge plate 7 is connected with the driving mechanism 4.
The travelling wheel 6 is provided with a clamping groove 601, and the edge of the guide rail groove 301 is provided with a convex part 302 matched with the clamping groove 601.
The number of the road wheels 6 is plural.
The anti-falling rollers 8 are multiple in number.
Example 1:
under the normal operating condition of door system, adjust the eccentric shaft position and make and remain the 2mm clearance between gyro wheel and the vertical limit of layering, do not contact with the layering, do not hinder opening and shutting of door leaf, when door system broke down, door leaf top driving wheel deviates from among the load bearing mechanism =, and is spacing to the gyro wheel through the layering to reach the upper portion limit function of door leaf, prevent that door system from deviating from the automobile body.
The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
