Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with accompanying drawing, but should not be interpreted as that the scope of the subject matter of the present invention is limited to following embodiment, under the situation of not departing from above-mentioned technical idea of ​​the present invention, all according to the common technical knowledge of this field and Various modifications, substitutions and alterations made by conventional means are included within the scope of the present invention.

[0016] Such as Figure 1-4 As shown, a T-shaped opening spring self-locking nut includes a nut body 1 and a spring 2. The spring 2 is arranged in the nut body 1. The pitch of the spring 2 is consistent with the thread pitch of the nut body 1. The same pitch means that the helix of the spring 2 One turn, that is, the length of one turn of the nut thread after 360° is the same; wherein, the main function of the nut body 1 is to bear the loa...

Abstract

The invention relates to a T-shaped split ring self-locking nut which is applied to the technical field of railway transportation equipment. The T-shaped split ring self-locking nut comprises a nut body and a spring, wherein the spring is arranged in the nut body; a screw pitch of the spring is consistent to a screw pitch of a screw thread of the nut; a T-shaped slot is formed in one hexagonal surface of the nut body; three closing ports are formed in one threadless end in the nut body; a first convex body and a second convex body are arranged at the head end and the tail end of the spring, and stretch out of an opening of the T-shaped slot from the inner part of the nut body; and the spring is clamped into the T-shaped slot. The T-shaped split ring self-locking nut provided by the invention is simple in structure; the spring is arranged in the nut body, so that a fixing function is realized; and the spring has stretchability and contractibility, so that a self-locking performance of the nut can be effectively improved, a nut-bolt fastening system cannot be loosened after a long time during a use process, and the maintenance times and the labor cost are effectively reduced.

Description

technical field [0001] The invention relates to a T-shaped open spring self-locking nut used in the rail transit field. technical background [0002] At present, many fastening connection systems with nuts and bolts are used on bullet trains, high-speed rail locomotives, and rails. However, ordinary nuts and bolts fastening connection systems have poor locking performance due to ordinary threaded connections. Loosening phenomenon requires frequent inspection and tightening. [0003] Chinese Patent No. 201520239929.X Application Date: 2015-04-20 discloses a spring self-locking nut, including a nut body, the inner wall of the nut body is provided with threads, and the tail of the nut is provided with a tray, the tray A spring seat is provided on the inner wall of the spring seat, a spring is provided inside the spring seat, and a baffle is provided at the upper end of the spring. Its disadvantages are: the structure is complicated, the spring is arranged outside the nut body...
