Background technology

At present, the function of mechanical lock becomes increasingly complex, and its control mode is also more and more loaded down with trivial details, causes the mechanical lock easy damage, repairs also very inconvenient.

The utility model content

To above deficiency, it is a kind of simple in structure that the utility model provides, and controls novel spring mechanical lock easily; Be formed with the housing of the cavity of up/down perforation in the middle of it comprises, the hypomere of said cavity is arranged with can be along its dead bolt that moves up and down, and said dead bolt can move down and stretch out said cavity; The epimere of said cavity is arranged with can be along its depression bar that moves up and down; Said cavity is stretched out on the top of said depression bar, and the top of said dead bolt is formed with the pin-and-hole of vertical setting, and the bottom of depression bar is nested in the said pin-and-hole and along it and moves up and down; The upper end of said dead bolt is provided with jump ring; The middle-end of said depression bar is provided with the last snap ring that can prop up cavity top inwall, and the lower end inwall of cavity is provided with the following snap ring that entangles dead bolt, is provided with upper spring between said jump ring and the last snap ring; Be provided with lower spring between said jump ring and the following snap ring, the stiffness factor of said lower spring is greater than the stiffness factor of upper spring.

The internal diameter of said depression bar lower end is less than the internal diameter of its upper end, and the internal diameter of depression bar lower end is suitable with the internal diameter of said pin-and-hole.

The external diameter of said dead bolt upper end is suitable with the external diameter of depression bar upper end.

The external diameter of the dead bolt of snap ring below is greater than the internal diameter of following snap ring under said being positioned at.

The two ends of said upper spring and lower spring are respectively arranged with pad.

Be formed with several installing holes on the said housing.

The beneficial effect of the utility model: the spring mechanical of the utility model lock since the stiffness factor of lower spring greater than the stiffness factor of upper spring; In original state; The pressure of lower spring is greater than the pressure of upper spring, and last snap ring props up cavity top inwall, in the dead bolt indentation cavity; In the time of locking, give downward pressure of depression bar through external force, the pressure differential through lower spring and upper spring ejects cavity with dead bolt, and dead bolt inserts in the purpose that can realize locking in the corresponding lock pin; In the time of release, only need discharge the pressure that acts on the depression bar, utilize the pressure differential of lower spring and upper spring can automatically restore to original state again, the utility model is simple in structure, and control is convenient.

Description of drawings

Fig. 1 is the structural representation of the spring mechanical lock of the utility model;

Fig. 2 is the structure cross-sectional schematic of the spring mechanical lock of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further set forth, wherein, the direction of the utility model is standard with Fig. 1.

As depicted in figs. 1 and 2, the spring mechanical lock of the utility model comprises housing 1, is formed with several installing holes 6 on the housing 1; The centre of housing 1 is formed with the cavity 11 of up/down perforation, and the hypomere of cavity 11 is arranged with dead bolt 2, and dead bolt 2 can move up and down along cavity 11; And can stretch out cavity 11 (in original state, in the dead bolt 2 indentation cavitys 11, in locking; Dead bolt 2 ejected cavity 11 a little, the one section dead bolt 2 that stretches out cavity 11 is inserted into the purpose that can realize locking in the corresponding lock pin), the epimere of cavity 11 is arranged with depression bar 3; Depression bar 3 can move up and down along cavity 11, and cavity 11 is stretched out on the top of depression bar 3, can in cavity 11 indentation at the effect down-pressed pole 3 of external force; The top of dead bolt 2 is formed with the pin-and-hole 21 of vertical setting; The bottom of depression bar 3 is nested in the pin-and-hole 21 and along it and moves up and down, and the upper end of dead bolt 2 is provided with jump ring 22, and the middle-end of depression bar 3 is provided with the last snap ring 31 that can prop up cavity 11 top inwalls; The lower end inwall of cavity 11 is provided with the following snap ring 111 that entangles dead bolt 2; Be provided with upper spring 41 between jump ring 22 and the last snap ring 31, be provided with lower spring 42 between jump ring 22 and the following snap ring 111, the stiffness factor of lower spring 42 is greater than the stiffness factor of upper spring 41.

Like this, because the stiffness factor of lower spring 42 is greater than the stiffness factor of upper spring 41, in original state, the pressure of lower spring 42 is greater than the pressure of upper spring 41, causes snap ring 31 to prop up the inwall on cavity 11 tops, in the dead bolt 2 indentation cavitys 11; In the time of locking, apply a pressure that is directed downwards for depression bar 3 through external force, through the pressure differential of lower spring 42 with upper spring 41, dead bolt 2 is ejected cavity 11, dead bolt 2 inserts in the purpose that can realize locking in the corresponding lock pin; In the time of release, only need discharge the pressure that acts on the depression bar 3, utilize the lower spring 42 and the pressure differential of upper spring 41 can automatically restore to original state again, simple in structure, control is convenient.

Wherein, The internal diameter of depression bar 3 lower ends is less than the internal diameter of its upper end; The internal diameter of depression bar 3 lower ends is suitable with the internal diameter of pin-and-hole 21; The external diameter of the external diameter of dead bolt 2 upper ends and depression bar 3 upper ends is suitable, and the external diameter of the dead bolt 2 of snap ring 111 belows is greater than the internal diameter of following snap ring under being positioned at, and the two ends of upper spring 41 and lower spring 42 are respectively arranged with pad 5.

The above is merely preferred embodiments of the present invention; The present invention is not limited to above-mentioned embodiment; In implementation process, possibly there is local small structural modification; If various changes of the present invention or modification are not broken away from the spirit and scope of the present invention, and belong within claim of the present invention and the equivalent technologies scope, then the present invention also is intended to comprise these changes and modification.
