Detailed Description
In order to make the objects, contents and advantages of the present invention clearer, the following detailed description of the embodiments of the present invention will be made in conjunction with the accompanying drawings and examples.
The embodiment provides an anti-falling adjustable locking device, which has a structure shown in fig. 1 and comprises an inner nut 1, an intermediate washer 2, an outer nut 3, a cylindrical pin 4 and a locking screw 5.
Wherein, a cylindrical pin hole is processed on the side of the central hole of the inner nut 1 for inserting a cylindrical pin 4. The periphery of the central hole of the middle gasket 2 is provided with evenly distributed positioning holes 6, and the edge of the central hole is provided with a boss 7, as shown in fig. 2. A locking screw hole is processed at the side of the central hole of the outer nut 3 and used for inserting a locking screw 5.
The use method of the anti-falling adjustable locking device is as shown in fig. 3, firstly, the inner nut 1 is sleeved on the wheel shaft 8 through the central hole of the inner nut, so that the inner end surface of the inner nut 1 is close to the outer end surface of the outer side bearing 9 on the wheel shaft 8. And inserting the cylindrical pin 4 into the cylindrical pin hole on the inner nut 1, and enabling the outer end of the cylindrical pin 4 to protrude out of the outer end surface of the inner nut 1. The inner nut 1 is screwed up clockwise by a torque wrench and then is reversely rotated for three circles, so that the inner nut 1 and the bearing 9 are tightly propped.
The middle washer 2 is sleeved on the wheel shaft 8 through the central hole, the boss 6 of the middle washer 2 is clamped into the key groove 10 on the wheel shaft 8, as shown in fig. 4, a locking state with the wheel shaft 8 is achieved, and the middle washer 2 can be driven to rotate when the wheel shaft 8 rotates.
The cylindrical pin 4 on the inner nut 1 is inserted into the corresponding positioning hole 6 on the middle gasket 2, so that the inner end surface of the middle gasket 2 is close to the outer end surface of the inner nut 1, and the wheel axle 8 is limited. And finally, sleeving the outer nut 3 on a wheel shaft 8 through a central hole of the outer nut, pressing the middle gasket 2 and the inner nut 1 tightly, and screwing the locking screw 5 into the locking screw hole of the outer nut 3 and extending into the corresponding positioning hole 6 on the middle gasket 2.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, it is possible to make various improvements and modifications without departing from the technical principle of the present invention, and those improvements and modifications should be considered as the protection scope of the present invention.
