Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In order to solve the current problem that to open roll-over door weight is big, can not direct manual operation upset, the utility model provides a take helping hand's roll-over door link mechanism. With particular reference to figures 1 to 3.
As shown in fig. 1, the present embodiment provides a link mechanism with power assist for a roll-over door, the roll-over door is mounted on an upper frame 1 through a link mechanism, the roll-over door is used for opening and closing a compartment of an emergency vehicle, and the roll-over door includes an upper roll-over door 4 and a lower roll-over door 10. The link mechanism comprises a bearing seat 2, a first connecting rod 3, a second connecting rod 5, a third connecting rod 6, a triangular connecting rod 7, an air spring 8 and a fourth connecting rod 9. The bearing seat 2 is fixedly arranged at the top of the upper frame 1, one end of the first connecting rod 3 is rotatably connected with the bearing seat 2 through a rotating shaft, and the other end of the first connecting rod is hinged with a first position at the top end of the upper turnover door 4; one end of the second connecting rod 5 is hinged with one side of the upper frame 1, and the other end of the second connecting rod is hinged with the bottom of the upturned door 4; the top end of the third connecting rod 6 is hinged with a second position of the top end of the upturned door 4, and the other end of the third connecting rod is hinged with a first corner of the triangular connecting rod 7; the first end of the gas spring 8 is fixed at the bottom of the upper frame 1, and the other end of the gas spring is hinged with the second corner of the triangular connecting rod 7; the triangular connecting rod 7 is fixed on a side plate of the upper frame 1 through a rotating shaft; one end of the fourth connecting rod 9 is hinged with the bottom of the downward turning door 10, and the other end of the fourth connecting rod is hinged with the third corner of the triangular connecting rod 7; the lower turnover door 10 is fixedly installed at the bottom of the upper assembly frame 1 through a hinge.
The operating principle of the turnover door connecting rod mechanism is as follows: as shown in fig. 2, when the car needs to be opened, the handle outside the downward-turning door 10 is pulled, the downward-turning door 10 naturally turns downward through gravity, and meanwhile, the reverse thrust given by the gravity of the gas spring 8 and the upward-turning door 4 is offset with the gravity of the downward-turning door 10, so that the personnel only need to lightly hold the downward-turning door until the downward-turning door is perpendicular to the ground, and the downward-turning door can be opened to take and place the equipment in the car body. As shown in figure 3, when the turnover door needs to be closed, the downward turnover door 10 is lifted, the triangular connecting rod 7 rotates anticlockwise under the left and right gravity of the gas spring 8 and the upward turnover door 4, meanwhile, the fourth connecting rod 9 is pulled to drive the downward turnover door 10 to rotate, the moment of the downward turnover door 10 is basically balanced, the downward turnover door 10 can be lifted by a small force, and then the upward and downward turnover doors rotate around respective movement axes until the upward and downward turnover doors are completely closed.
The utility model provides a take helping hand's turnover door link mechanism, but single manually operation's turnover door has solved the problem of turnover door upset difficulty from top to bottom, reasonable utilization moment simultaneously for turnover door 10 reaches basic balance when moment is the biggest respectively from top to bottom, the condition that the sudden drop of door or bounce can not appear turning over, personnel's operation is light, safety.
The above description of the present invention does not limit the scope of the present invention. Any other corresponding changes and modifications made according to the technical idea of the present invention should be included in the scope of the claims of the present invention.
