The second is that pull bar is connected with joint screw thread, and further fixing to pull bar by cottor pin.But this kind mode need to be adjusted the position of joint on pull bar in advance, operates comparatively loaded down with trivial details.
The utility model content
In view of this, the utility model proposes a kind of automobile door lock and pull bar fastening devices thereof, pull bar is deviate from from joint and operated comparatively loaded down with trivial details problem to solve existing pull bar fastening devices.
An aspect, the utility model provide a kind of automobile door lock pull bar fastening devices, and a kind of automobile door lock pull bar fastening devices is arranged between pull bar and the connector, and this device comprises joint; Wherein, described joint is connected in described connector, is provided with connecting hole on the described joint; Described pull bar comprises into first paragraph and the second segment that angle is arranged; Described first paragraph is arranged in the described connecting hole; And, be provided with escapement between described connecting hole and the described first paragraph.
Further, in the above-mentioned fastening devices, described escapement comprises: be arranged with in the groove of described first paragraph outer wall; Be convexly set in the projection of described connecting hole inwall; And described projection is embedded in the described groove.
Further, in the above-mentioned fastening devices, described groove is at least two, and circumferentially evenly distributes along the outer wall of described first paragraph; Described projection is at least two, and circumferentially evenly distributes along the inwall of described connecting hole.
Further, in the above-mentioned fastening devices, described groove is annular, and is located on the outer wall of described first paragraph; Described projection is annular, and is located on the inwall of described connecting hole.
Further, in the above-mentioned fastening devices, described joint is extended with limited block to the outside of described connector, and the sidewall of described limited block offers draw-in groove; The second segment of described pull bar is held in the described draw-in groove.
The utility model has increased escapement between connecting hole and pull bar, when pull bar moved, this escapement can produce axial resistance between pull bar and joint, prevents that pull bar from deviating from from joint.Compare with existing locate mode, reliability is high, and is simple in structure, easy operating.
On the other hand, the utility model also provides a kind of automobile door lock, and this door lock is provided with above-mentioned any automobile door lock pull bar fastening devices.
Because the automobile door lock pull bar has above-mentioned effect with fastening devices, also has corresponding technique effect so have this automobile door lock that fixedly goes to.
