Detailed Description

The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

Referring to fig. 1, the safety shifting piece 1 is a long and narrow plate structure, two sides of one end of the safety shifting piece 1 are oppositely provided with a convex part 11, and the convex part 11 is a hemispherical structure. In the use, because its size overlength, when assembling lock structures such as lock, in order to assemble the convenience, insurance plectrum 1 can not assemble together with the lock body, needs the master of lock structures such as installation lock to install insurance plectrum 1 by oneself. However, the structure of the insertion mechanism for installing the safety shifting piece 1 is complex, and the installation is inconvenient and complicated.

In order to solve the above problems existing in the insertion mechanism of the existing installation safety shifting piece 1, the utility model provides a simple structure, simple to operate's safety shifting piece insertion mechanism 100.

Referring to fig. 2-5, in the present embodiment, the safety catch mechanism 100 includes a knob 2 and a circlip 3.

Wherein, the knob 2 is provided with a rotary rod 21, the end surface of the free end of the rotary rod 21 is provided with a socket 211 along the length direction of the rotary rod 21, and the width of the socket 211 is adapted to the width of the safety shifting piece 1 so as to facilitate the insertion and the stability of the safety shifting piece 1.

The side surface of the free end of the rotary rod 21 is provided with an annular groove 212, and the annular groove 212 is arranged at a distance from the bottom of the socket 211 so as to be convenient for clamping the safety shifting piece 1. The size of the elastic retainer ring 3 is matched with that of the ring groove 212, and the elastic retainer ring 3 is clamped in the ring groove 212.

The socket 211 extends to a predetermined length from the front of the rotary rod 21, the ring groove 212 is transversely provided at the waist of the socket 211, the front of the rotary rod 21 located in front of the ring groove 212 is formed into a wedge-shaped structure 214 with a smaller front part and a larger rear part, and the wedge-shaped structure 214 facilitates the separation of the safety catch 1 from the rotary rod 21.

Referring to fig. 6-7, after the safety shifting piece 1 is inserted into the socket 211 at the free end of the rotating rod 21, the protrusion 11 of the safety shifting piece 1 is located between the annular groove 212 and the bottom of the socket 211, so that the protrusion 11 is clamped between the elastic collar 3 and the bottom of the socket 211. At this moment, when inserting insurance plectrum 1 into the lock body in order to install insurance plectrum 1, after insurance plectrum 1 inserted the lock body, rotatable knob 2 perhaps stirred the knob 2 of insurance plectrum mechanism 100 about along the opening direction of socket 211, because circlip 3 has elasticity, the bellying 11 of insurance plectrum 1 can act on circlip 3 and make its outside deformation to bellying 11 of insurance plectrum 1 breaks away from circlip 3, and then makes insurance plectrum 1 and the separation of insurance plectrum mechanism 100, accomplishes the installation of insurance plectrum 1.

Specifically, referring to fig. 3-4, the knob 2 further has a knob head 22, and the knob head 22 facilitates to dial the safety dial plate inserting mechanism 100. The button head 22 includes a support block 221 and a protrusion 222, and the protrusion 222 is elongated so as to be pinched by the forefinger and the thumb to shift the safety shifting piece inserting and poking mechanism 100.

In addition, the protrusion 222 is disposed at one end of the abutting block 221, the rotating rod 21 is fixed at the other end of the abutting block 221, the length of the protrusion 222 is the same as the outer diameter of the abutting block 221, the outer diameter of the rotating rod 21 is smaller than the outer diameter of the abutting block 222, and the central axes of the rotating rod 21 and the abutting block 222 are the same, so that the safety catch 1 can be pushed.

Referring to fig. 3-4, the ring groove 212 is provided with a stopper 2121 to prevent the ring groove 212 from forming a closed groove, and prevent the circlip 3 from rotating in the ring groove 212, so as to be unfavorable for separating the protrusion 11 of the safety catch 1 from the circlip 3, in addition, the plane of the stopper 2121 is perpendicular to the plane of the ring groove 212, and the intersection of the socket 211 and the ring groove 212 is 90 degrees different from the stopper 2121 in circumference, so that the notch 31 of the stopper ring 3 is located at the intersection of the socket 211 and the ring groove 212, and the clamping of the safety catch pulling and inserting mechanism 100 and the safety catch 1 is unstable. And the plane of the annular groove 212 is perpendicular to the plane of the socket 211, so as to facilitate the separation of the boss 11 of the safety catch 1 from the circlip 3.

Referring to fig. 3-4, the rotating rod 21 is further provided with a fastening portion 213, and the fastening portion 213 is a ring groove structure with different groove depths. When the safety catch 1 is installed, the locking portion 213 is used to lock the lock body to stabilize the safety catch inserting and pulling mechanism 100.

Referring to fig. 5, the elastic collar 3 is a circular ring structure, and the elastic collar 3 has a notch 31, so that when the protrusion 11 of the safety shifting piece 1 acts on the elastic collar 3, the elastic collar 3 can deform greatly, so that the protrusion 11 and the elastic collar 3 can be separated from each other.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the same way in the protection scope of the present invention.
