Description
Technical Field
The utility model discloses be applied to stop gear's technical field, in particular to plug pin mechanism.
Background
In some mechanisms capable of adjusting the power output angle or direction, such as a screw tightening mechanism, which needs to adjust the angle to adapt to the position of a screw or the position of a screw hole, the traditional approach is to achieve the angle adjustment and the screw tightening driving by matching multiple sets of motors. However, the overall mechanism is cumbersome and costly. The existing technical difficulty is that the whole driving mechanism capable of rotating executes screwing work, namely, the driving motor and the screwing mechanism are in transmission connection and can rotate synchronously on the installation panel, the insertion and extraction pin is used as a fixing hole for connecting and matching the motor and the installation panel, the whole size is reduced while the working angle is changed, and the insertion and extraction pin needs to have a self-locking retaining function so as to meet the requirement that the operation is not influenced by automatic ejection in the adjusting process. In the actual working process, the plug-pull pin structure is usually a spring plunger, for example, an economical knob plunger of the mismi (china) precision mechanical trade limited company commonly used in the industry, which is installed through a thread structure. But because the plug pin is the consumable article, and the shearing force that the round pin post received has certain restriction when the motor work, when receiving great shearing force, thereby round pin post and plug pin body can receive certain deformation influence plug pin's performance, and wherein deformation can lead to can't demolising and maintain the change.
There is also chinese patent with publication No. CN103851050B, which discloses a bolt structure, which has the functions of self-locking and automatic reset extension, and the whole structure is bolt-fixing type, but because the pin column adopts sheet-shaped sheet metal parts for limiting, it is inferior in both smoothness and stability of movement.

The pin column is unlocked by rotating the rotating sleeve, so that the pin column extends out of the fixed seat to be limited. Simultaneously through adopting two sets of inclined planes to cooperate, realize removing the back of locking the rotating sleeve receives the effect of spring is followed down first inclined plane automatic re-setting, when the round pin post stretches out to keep, through first inclined plane with the cooperation of second inclined plane, because the design of plane laminating makes it need outwards to draw and just can rotate, and then the realization is right the rotating sleeve is spacing, avoids unexpected trigger unblock to lead to the mechanism action, improves the security.
Preferably, when the first inclined surface and the second inclined surface are attached, the first inclined surface and the second inclined surface are parallel.
According to the scheme, the design that the two groups of inclined surfaces are parallel is adopted, so that the rotating sleeve cannot rotate when being matched with the limiting seat, and the safety and the stability are improved.
One preferred scheme is that a handle is arranged on the rotating sleeve, and one end, far away from the rotating sleeve, of the handle is arc-shaped.
According to the scheme, the handle is arranged to facilitate operation of the rotating sleeve, and the arc-shaped end portion is convenient for a user to rotate, so that a force application point can be formed during rotation operation.
One preferred scheme is, the round pin post includes connecting portion and spacing portion, the diameter of spacing portion is greater than the diameter of connecting portion, the one end of spring with spacing seat cooperation, the other end of spring with spacing portion cooperation, the length of spacing portion is greater than the stroke of round pin post.
According to the scheme, the connecting part is used for connection transmission, and the rotating sleeve drives the limiting part to extend out of or retract into the fixing seat through the connecting part. And when the limiting part retracts, the spring is compressed to accumulate potential energy. Through the length of spacing portion is greater than the design of the stroke of round pin post makes when spacing portion stretches out there will be one section to be located in the fixing base, and then pass through the fixing base does spacing portion provides effectual support, guarantees spacing effect. The limiting part with larger diameter is adopted to improve the bearing capacity of the shearing force.
One preferred scheme is that a first guide copper sleeve matched with the limiting part is arranged on the fixing seat, and a second guide copper sleeve matched with the connecting part is arranged in the limiting seat.
According to the scheme, the first guide copper sleeve and the second guide copper sleeve are arranged, so that the connecting part and the limiting part are guided. The first guide copper bush and the second guide copper bush are also used for preventing the pin from being worn by the fixed seat, and therefore the service life of the fixed seat and the whole mechanism is prolonged.
According to a preferable scheme, the fixing seat comprises a base and a clamping seat, a through hole matched with the pin column is formed in the base, two ends of the through hole are in a step shape, one end of the through hole is matched with the first guide copper sleeve, the other end of the through hole is matched with the limiting seat, and the limiting seat penetrates through the clamping seat and is matched with the through hole.
According to the scheme, the quick and convenient assembly can be realized by adopting a split structure, and the replacement and maintenance of the first guide copper sleeve and the second guide copper sleeve are convenient to carry out.
