Abstract
The invention provides an upright locking mechanism. The upright locking mechanism comprises a movable upright and a base which are connected via a rotating shaft, wherein a rotary latch hook, a knob shifting fork and a reset shifting fork are connected to the base; a reset spring is arranged on each of the knob shifting fork and the reset shifting fork; branching support legs are formed at one end of the rotary latch hook and the two branching support legs are respectively clamped into the knob shifting fork and the reset shifting fork; a latch hook head and a latch hook support leg which are divergent are formed at the other end of the rotary latch hook; a lock hole corresponding to the latch hook head is formed in the movable upright; the movable upright oppresses the latch hook support leg to drive the rotary latch hook to rotate when rotating; the latch hook head is clamped into the lock hole.
Description
Technical field
The present invention relates to mechanical structure field, specifically a kind of column locking framework.
Background technique
Need the device of rotation at some, in such as seat or door and window, need to position pivotal position.The regulating positioning device of present use uses punching buckle or snap close to position and lock usually, and positioning precision is poor, uses inconvenience.
Summary of the invention
The present invention, in order to solve the problem of prior art, provides a kind of column locking framework, only needs operant activity parts, namely can the locking of automatic movable parts, easy to use.
The present invention includes the active column and pedestal that are connected by rotating shaft, described pedestal is connected with and rotates latch hook, turn-knob fork and reset fork, turn-knob fork and reset fork are equipped with Returnning spring.Described rotation latch hook one end has diverging legs, two bifurcated branches pin do not snap in turn-knob fork and reset fork, rotate latch hook head and latch hook leg that the latch hook the other end is bifurcated, active column has the lockhole corresponding with latch hook head position, when active column rotates, compressing latch hook leg driven rotary latch hook rotates, and latch hook head snaps in lockhole.
Beneficial effect of the present invention is: only need operant activity parts, namely can the locking of automatic movable parts, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is working procedure schematic diagram of the present invention.
Embodiment
Structure of the present invention as shown in Figure 1, is comprised the active column 1 and pedestal 2 that are connected by rotating shaft, it is characterized in that: described pedestal 2 is connected with and rotates latch hook 3, turn-knob fork 5 and reset fork 4, turn-knob fork 5 and reset fork 4 are equipped with Returnning spring.Described rotation latch hook 3 one end has diverging legs, two bifurcated branches pin do not snap in turn-knob fork 5 and reset fork 4, rotate latch hook head 7 and latch hook leg 6 that latch hook 3 the other end is bifurcated, active column 1 has the lockhole corresponding with latch hook head 7 position, oppress latch hook leg 6 driven rotary latch hook 3 when active column 1 rotates to rotate, latch hook head 7 snaps in lockhole simultaneously.
Working procedure of the present invention is as shown in Figure 2:
1, active column free state, latch hook head is positioned at releasing state.
2, when active column moves down, extruding latch hook leg, latch hook head snaps in lockhole, and the rotation rotating latch hook releases knob shift fork.
3, knob shift fork rotates to lock state under the pulling force effect of Returnning spring, and the rotation of knob shift fork releases reset shift fork.
4, reset shift fork rotates until encounter the diverging legs rotating latch hook under the pulling force effect of Returnning spring, now rotates latch hook and is in steady state.
5, turning knob shift fork, release latch hook, then reset shift fork turns to the position of hook knob shift fork under the pulling force effect of Returnning spring, and discharge though now rotate latch hook, movable part does not leave.
In the process of 6, mobile active column, rotation lock turns to release position under being hooked in the pulling force effect of Returnning spring, and pressed home shift fork rotates simultaneously, and the rotation of reset shift fork releases knob shift fork, but knob shift fork, by the impact rotating latch hook, is still in the lock state.
7, when again moving active column extruding and rotating latch hook, get back to initial free state, new samsara starts.
Embody rule approach of the present invention is a lot, and the above is only the preferred embodiment of the present invention, should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
