Abstract

The utility model relates to pinned connection technical field, in particular to a kind of lock clasp device, the end head of bearing pin arranges handle, the end, aperture of the attachment hole of to be connected arranges U-shaped bayonet socket, when handle rotates with bearing pin, its shaft can be in U-shaped bayonet socket or with U-shaped bayonet socket and be separated two kinds of location statuss, during installation, operator holds handle, bearing pin is inserted in attachment hole, then rotatable handle, namely handle may be stuck in U-shaped bayonet socket, and then the axial motion of bearing pin is limited, realize the installation of lock clasp device fast and easily, accordingly, counterrotating handle, handle is separated with U-shaped bayonet socket, the dismounting of lock clasp device can be realized.

Description

Lock clasp device

Technical field

The utility model relates to pinned connection technical field, particularly a kind of lock clasp device.

Background technique

At present, in the assembling process of mechanical part, locking between each component often adopts the mode of pinned connection, namely pivot pin connection inserts bearing pin in the attachment hole of to be connected, and the positioning hole place insertion opening pin then on bearing pin is locked, in actual mechanical process, due to the spatial constraints between to be connected and other mechanical parts, cotter pin may be inconvenient to insert in the positioning hole of bearing pin, and then can cause the installation and removal inconvenience of lock clasp device, affects working efficiency.

Model utility content

The purpose of this utility model proposes a kind of lock clasp device being convenient to installation and removal.

For achieving the above object, the technical solution adopted in the utility model is: a kind of lock clasp device, the end head of bearing pin arranges handle, the end, aperture of the attachment hole of to be connected arranges U-shaped bayonet socket, and when handle rotates with bearing pin, its shaft can be in U-shaped bayonet socket or with U-shaped bayonet socket and be separated two kinds of location statuss.

Compared with prior art, the utility model possesses following technique effect: arrange handle in the end head of bearing pin, the end, aperture of the attachment hole of to be connected arranges U-shaped bayonet socket, during installation, operator holds handle, bearing pin is inserted in attachment hole, then rotatable handle, namely handle may be stuck in U-shaped bayonet socket, and then limits the axial motion of bearing pin, realizes the installation of lock clasp device fast and easily, accordingly, counterrotating handle, handle is separated with U-shaped bayonet socket, can realize the dismounting of lock clasp device.

Embodiment

Below in conjunction with Fig. 1-Fig. 5, the utility model is described in further detail.

A kind of lock clasp device, the end head of bearing pin 10 arranges handle 20, and the end, aperture of the attachment hole of to be connected A arranges U-shaped bayonet socket 30, and when handle 20 rotates with bearing pin 10, its shaft can be in U-shaped bayonet socket 30 or be separated two kinds of location statuss with U-shaped bayonet socket 30.During installation, hold handle 20, bearing pin 10 is injected in the attachment hole of to be connected A, rotatable handle 20 is in U-shaped bayonet socket 30, the axial motion of bearing pin 10 can be limited, counterrotating handle 20, handle 20 is separated with U-shaped bayonet socket 30, can realize the installation of bearing pin 10, dismounting and locking fast and easily.

As further preferred version: described U-shaped bayonet socket 30 is connected and composed with to be connected A by a L-type bar 31, and one end of L-type bar 31 is connected with to be connected A, and the other end freely upwards overhangs, and forms U-shaped bayonet socket 30 between the shaft of L-type bar 31 and link A.Overhang fixing for a L-type bar 31 on the surface of to be connected A, make to form U-shaped bayonet socket 30 between L-type bar 31 and to be connected A, structure is simple, and is easy to handle 20 to rotate to U-shaped bayonet socket 30 or is separated with U-shaped bayonet socket 30.

Preferably, side's annular that described handle 20 is bent into for rod member, one side rod body is connected with bearing pin 10, separately has the parallel to an axis of a pair shaft and bearing pin 10.By handle 20 side of being designed to annular, be easy to the gripping of operator to handle 20, and then be beneficial to the rotation of the installation of bearing pin 10, dismounting and handle 20.

Described handle 20 is straight-bar, and the axial direction of straight-bar and bearing pin 10 is arranged vertically.Benefit handle 20 being designed to straight-bar is that the structure of straight-bar is simple, can reduce costs.
