Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention will be described in detail with reference to the accompanying drawings and the specific embodiments, but the scope of the present invention is not limited in any way.
As shown in fig. 1 and fig. 2, the first embodiment of the present invention is suitable for an anti-disassembly tooth-shaped engaging nut assembly, and the structure of the first embodiment of the present invention includes a sleeve 2, a spring 3, a nut core shaft 4, a retainer ring 5 and a nut cover 6. The nut mandrel 4 is provided with a wedge-shaped tooth structure which is used for being meshed with the wedge-shaped tooth structure on the nut cover 6, so that the disassembly prevention function is realized, and the processing is more convenient. The assembling method of the nut component comprises the following steps: the spring 3 is arranged in the nut mandrel 4 and then arranged in the sleeve 2, the nut mandrel 4 can move in the axial direction in the sleeve 2, and the spring 3 is arranged in the sleeve 2, so that the nut mandrel 4 can be subjected to elastic force when moving in the axial direction; the inner diameter of the sleeve 2 here is the same as the outer diameter of the nut cap 6; the retainer ring 5 is arranged in a space formed by matching an annular groove formed in the circumference of the inner side wall of the sleeve 2 with an annular groove formed in the circumference of the outer side wall of the nut cover 6, so that the sleeve 2 and the nut cover 6 are prevented from moving axially, and the anti-disassembly effect is achieved.
The retaining ring used here is therefore not a standard retaining ring, but an anti-disassembly retaining ring, which is circular in shape and is provided with a notch. The outer diameter of the retainer ring 5 is larger than the inner diameter of the groove of the sleeve 2 and larger than the outer diameter of the nut cover 6; the groove depth of the nut cap 6 is larger than the section diameter of the retainer ring 5, and the outer diameter of the outer side wall of the nut cap is larger than the inner diameter of the retainer ring 5. When the retainer ring 5 is arranged in the groove of the sleeve 2, the gap is compressed to be smaller, and the outer diameter of the gap is also compressed to be smaller; in this case, the inner diameter of the retainer ring 5 is smaller than the inner diameter of the inner side wall of the sleeve 2.
The retainer ring 5 is first installed in the groove of the nut cap 6 and then assembled into the hole of the sleeve 2, but the range of the retainer ring 5 becomes small, and it is difficult to fit into the hole. The special jig 1 is designed to be a cylindrical structure, the first end of the jig is an inlet, and the second end of the jig is an outlet; the first end opening of tool 1 is greater than the second end opening, and the circumference area of tool 1 inside wall diminishes gradually from its first end opening to second end opening. As shown in fig. 3 to 5, the bottom of the jig 1 is provided with a step arranged below the opening of the second end; sleeving the step of the jig 1 on the outer side wall of the top of the sleeve 2, wherein the inner side wall of the opening of the second end of the jig 1 is matched with and is continued to the inner side wall of the sleeve 2; the retainer ring 5 is sleeved in the groove of the nut cover 6, enters the jig 1 from the first end inlet, and enters the sleeve 2 from the second end outlet until the groove of the sleeve 2 is aligned with the groove of the nut cover 6. In the process that the nut cover 6 drives the check ring 5 to enter the jig, the outer diameter of the check ring 5 is gradually compressed and reduced by the inner wall of the jig 1; and when the pipe comes out from the outlet of the jig 1, the outer diameter of the retainer ring is consistent with the outer diameter of the outer side wall of the nut cover 6. The nut cover 6 continues to move until the annular groove on the inner side wall of the sleeve 2 and the annular groove on the outer side wall of the nut cover 6 are matched to form a space; at this time, the notch of the retainer ring 5 becomes large, so that the outer side of the retainer ring 5 is fitted into the groove of the sleeve 2, and the inner side of the retainer ring 5 is in contact with the groove of the nut cap 6, thereby achieving an effect of excellent anti-removal performance, and improving the concealing performance of the retainer ring 5.
As shown in fig. 5 and 6, the jig 1 can be slowly taken out after the installation. At the moment, a nut mandrel 4 arranged in the sleeve 2 is in contact with the nut cover 6; the contact surface of the nut mandrel 4 and the nut cover 6 is an inclined surface with two wedge-shaped tooth structures.
The utility model discloses retaining ring, tool that use not only are applicable to the connection of sleeve 2 and nut lid 6, still are applicable to arbitrary axle part and set up the retaining ring at its inslot, together install the downthehole of trompil part, make the retaining ring get into within the groove of trompil part and the groove of axle part cooperate the space that forms to help axle part and trompil part form the combination of anti-disassembly.
While the present invention has been described in detail with reference to the preferred embodiments, it should be understood that the above description should not be taken as limiting the invention. Numerous modifications and alterations to the present invention will become apparent to those skilled in the art upon reading the foregoing description. Therefore, the scope of the present invention should be determined by the appended claims.
