The specific embodiment
In order better to understand the utility model, below in conjunction with specific embodiments and the drawings, the utility model is conducted further description.
The utility model relates to a kind of linkage that prevents that tongue from creeping, and please refer to Fig. 1 and Fig. 2, comprising:
One indication rod 1, is provided with external screw thread on described indication rod 1;
One connecting iron 9, has a circular hole on described connecting iron 9, fixes an oscillating bearing 8 in its circular hole, because the external diameter of oscillating bearing 8 is less than the diameter of circular hole on connecting iron 9, so be provided with the cover plate 7 for circular hole described in shutoff in a side of described oscillating bearing 8.Described cover plate 7 is square, has the hole matching with described circular hole on it, and on cover plate 7, the diameter in hole is less than the diameter of circular hole on connecting iron 9, and described cover plate 7 is fixing with connecting iron 9 by four rivets 5, thereby forms connecting iron assembly;
On described indication rod 1, be fixed with successively the first nut 2, the first securing member 3, connecting iron assembly, the second securing member 6 and the second nut 10;
Described the first securing member 3 is cylindrical shape, is provided with internal thread on it.
Described the second securing member 6 is cylindrical shape, and the internal thread arranging on it is connected by screw thread with indication rod 1.Described connecting iron assembly is sleeved on described the second securing member 6.In addition, on the second securing member 6, be also provided with external screw thread, on externally threaded length and the first securing member 3, internal thread is equal in length, and the first securing member 3 is connected by screw thread with the second securing member 6, and the part that the second securing member 6 contacts with oscillating bearing 8 is not established external screw thread.
On the contact surface of described the first securing member 3 and described connecting iron 9, be provided with rubber ring 4, on the contact surface of described the second securing member 6 and described cover plate 7, be also provided with rubber ring 4.
Assembling process of the present utility model is:
First in the circular hole of oscillating bearing 8 press-in connector iron 9, one side installs cover plate 7 additional, then with four rivets 5, cover plate 7 is fixed on connecting iron 9, and cover plate 7 can not affect the rotation of oscillating bearing 8, obtains connecting iron assembly;
Secondly, on indication rod 1, first screw in the first nut 2, then put the first securing member 3(and have internal thread on it), penetrate again rubber ring 4, then load onto above-mentioned connecting iron assembly, then penetrate a rubber ring 4, it has internal and external screw thread to screw in the second securing member 6(), the external screw thread of the second securing member 6 screws mutually with the internal thread of the first securing member 3, and connecting iron assembly is fixed on indication rod 1, finally screws in the second nut 10 fixing.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the utility model scope and improvement etc., within all should still belonging to this patent covering scope.
