Utility model content
Technical problem to be solved in the utility model is: provide a kind of two-way automatic lock, do not need instrument in use, and can be carried out locking or dismantling by article fast.
For solving the problems of the technologies described above, the utility model proposes a kind of two-way automatic lock, the thrust mechanism comprising handle, locking bar, commutation block and be arranged on handle, described handle is provided with an installing hole, be movably equipped with an outer teeth nut in described installing hole, the upper end of described locking bar is connected by screw thread pair with the internal thread of outer teeth nut;
Described commutation block is hinged on handle, one end of this commutation block is provided with the first ratchet and the second ratchet, described first ratchet and the second ratchet are used for alternately engaging each other with the external tooth of outer teeth nut, and the opposite end that described commutation block is provided with the first ratchet and the second ratchet abuts with the drive end of described thrust mechanism.
Further, retaining mechanism is provided with between the top of described locking bar and outer teeth nut, described retaining mechanism comprises screw, spring and is provided with cavity and outer peripheral pinch roller, the outward flange of described pinch roller is pressed together on the top of outer teeth nut, described screw is connected with the upper end end winding support of locking bar through after the cavity of pinch roller, be provided with position-arresting disk on the top of screw, the two ends of described spring are connected between position-arresting disk and cavity respectively.
Further, transition plate is provided with between the edge of described pinch roller and the top of outer teeth nut.
Further, the sidewall of described commutation block is provided with poke rod.
Further, the opposite end that described commutation block is provided with the first ratchet and the second ratchet is provided with the limiting section cooperatively interacted with the drive end of thrust mechanism.
Further, the top of described outer teeth nut is provided with the locating part extended internally, and described locating part is less than the externally threaded external diameter of locking bar to the distance at outer teeth nut center.
Preferably, described thrust mechanism is ripple pearl assembly.
Technique scheme at least has following beneficial effect: the utility model adopts and transmits bi-directional drive power at the outside teeth nut of commutation block, does not need instrument in use, can be carried out locking or dismantling by article fast.

Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figures 1 to 4, the utility model two-way automatic lock comprises handle 1, locking bar 2, commutation block 3, thrust mechanism 4, outer teeth nut 5, retaining mechanism 6, wherein, handle 1 is provided with an installing hole 11, be arranged in installing hole 11 by outer teeth nut 5, outer teeth nut 5 is connected by screw thread pair with the upper end of locking bar 2; Commutation block 3 is hinged on handle 1, one end of commutation block 3 is provided with the first ratchet 31 and the second ratchet 32, first ratchet 31 and the second ratchet 32 are for alternately engaging each other with the external tooth of outer teeth nut 5, the other end of commutation block 3 abuts with the drive end of thrust mechanism 4, the sidewall of commutation block 3 is provided with poke rod 33, conveniently stir commutation block 3, change driving direction.In the present embodiment, thrust mechanism 4 adopts ripple pearl assembly, and is provided with the limiting section 34 matched with ripple pearl on commutation block 3, when stirring poke rod 33 and changing the meshing relation of the first ratchet 31 and the second ratchet 32 and outer teeth nut 5, stir and be rich in timing, experience effect is better.
Retaining mechanism 6 is arranged between the top of locking bar 2 and outer teeth nut 5, particularly, retaining mechanism 6 comprises screw 61, spring 62 and is provided with the pinch roller 63 of cavity 631, the edge of pinch roller 63 is pressed together on the top of outer teeth nut 5, screw 61 is connected with the upper end end winding support of locking bar 2 through after the cavity 631 of pinch roller 63, the top of screw 61 is provided with position-arresting disk 64, and the two ends of spring 62 are connected between position-arresting disk 64 and cavity 631 respectively.Preferably, between the edge of pinch roller 63 and the top of outer teeth nut 5, be provided with transition plate 7, prevent outer teeth nut 5 from wearing and tearing.Retaining mechanism 6 can prevent locking bar 2 to same direction unrestricted motion.
The top of outer teeth nut 5 is provided with the locating part 51 extended internally, and locating part 51 is less than the externally threaded external diameter of locking bar 2 to the distance at outer teeth nut 5 center, stops locking bar 2 to move up.
During work, rotary handle 1, by the first ratchet 31 or the second ratchet 32 and matching of outer teeth nut 5 on commutation block 3, only need to change the first ratchet 31 and outer teeth nut 5 or the meshing relation between the second ratchet 32 and outer teeth nut 5 by poke rod 33, just can change screw thread rotation direction, use ratchet principle, reach bi-directional combination motion, realize bidirectional rotation, do not need instrument in use, can fast article be carried out locking or dismantling, and outward appearance lines are perfect, volume is little, simultaneously easy to operate, time saving and energy saving.
The above is detailed description of the invention of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some amendments, these amendments are also considered as protection domain of the present utility model.
