Tear the hinge open earlier with traditional, tear open again and wait to overhaul the part and compare, the utility model discloses easy dismounting conveniently overhauls.
Drawings
Fig. 1 is a schematic view of a hinge for a rail vehicle according to the present invention.
Fig. 2 is an exploded view of fig. 1.
Fig. 3 is a schematic view of the rotating shaft of the present invention.
In the figure:
the fixing piece comprises a fixing piece 1, a first fixing hole 1.1, a first shaft hole 1.2, a rotating piece 2, a second fixing hole 2.1, a second shaft hole 2.2, a locking hole 2.3, a rotating shaft 3, a stop cap 3.1, a groove 3.2, a rod part 3.3 and a locking screw 4.
Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Referring to fig. 1-2, the present invention relates to a hinge for a rail vehicle, which comprises a fixed member 1, a rotating member 2, a rotating shaft 3 and a locking screw 4;
the fixing piece 1 is U-shaped, two first fixing holes 1.1 are formed in the bottom of the fixing piece 1, the fixing piece 1 is fixedly connected with a vehicle body (not shown in the figure) through the first fixing holes 1.1, and first shaft holes 1.2 are formed in two sides of the fixing piece 1 respectively;
one side of the rotating piece 2 is provided with two second fixing holes 2.1, the rotating piece 2 is fixedly connected with a door or a rotating part through the second fixing holes 2.1, the other side of the rotating piece 2 is provided with a straight-through second shaft hole 2.2, the second shaft hole 2.2 corresponds to the first shaft hole 1.2, and the second shaft hole 2.2 is the same as the first shaft hole 1.2 in pore diameter; a locking hole 2.3 with an internal thread is formed in the rotating piece 2, the locking hole 2.3 is communicated with the second shaft hole 2.2 and is vertical to the second shaft hole, and the locking hole 2.3 is matched with a locking screw 4 with an external thread;
referring to fig. 3, the rotating shaft 3 includes a stop cap 3.1 and a rod portion 3.3, the stop cap 3.1 is located at the end of the rod portion 3.3, an annular groove 3.2 is formed in the middle of the rod portion 3.3, and the head of the locking screw 4 abuts against and is locked with the annular groove 3.2; the diameter of the stop cap 3.2 is larger than the aperture of the first shaft hole 1.2, the diameter of the rod part 3.3 is smaller than the aperture of the first shaft hole 1.2, and the stop cap 3.1 can effectively prevent the rotating shaft 3 from falling into the first shaft hole 1.2 during installation.
The working principle is as follows:
referring to fig. 1, during installation, the fixing member 1 is sleeved on one side of the rotating member 2, so that the second shaft hole 2.2 of the rotating member 2 corresponds to the first shaft hole 1.2 of the fixing member 1, then the rod part 3.3 of the rotating shaft 3 penetrates through the first shaft hole 1.2 and the second shaft hole 2.2, the stop cap 3.1 of the rotating shaft 3 abuts against the top edge of the rotating member 2, finally the locking screw 4 is screwed into the locking hole 2.3 until the head part of the locking screw 4 abuts against the annular groove 3.2 of the rotating shaft 3, so that the locking of the rotating member 2 and the rotating shaft 3 is completed, and at the moment, the rotating member 2 can rotate around the fixing member 1; when the door or the rotating part fixedly connected with the rotating part 2 needs to be overhauled, the locking screw 4 only needs to be unscrewed, the rotating shaft 3 is pulled out, the part to be overhauled and the rotating part 2 can be detached together, and after the overhaul is finished, the reinstallation is also very convenient.
