The usefulness of the utility model is: whole latch mechanism Stability Analysis of Structures, simple and practical, easy access maintenance reduce production costs simultaneously greatly.
Description of drawings
Fig. 1 is the structural representation that is used to lock forms parts of a preferred embodiment of the latch mechanism that is applicable to windows of railway vehicles of the utility model;
Fig. 2 be in the preferred embodiment of the latch mechanism that is applicable to windows of railway vehicles of the utility model since latch mechanism from the structural representation of latching segment.
The implication of Reference numeral among the figure:
1, lock body, 2, handle, 3, caging bolt, 4, spring, 5, rotary locking cylinder, 6, support bar, 7, the backstop bolt, 8, latch hook, 9, limiting through hole.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done concrete introduction.
See figures.1.and.2, the latch mechanism that is applicable to windows of railway vehicles of the utility model mainly comprises: lock body 1, lock handle spare, caging bolt 3, spring 4, rotary locking cylinder 5, support bar 6, backstop bolt 7.Wherein lock handle spare is divided into handle 2 and latch hook 8.
With reference to Fig. 1, lock body 1 and lock handle spare carry out hinged, and hinge is parallel to horizontal approach, so; Move handle 2, latch hook 8 can rotate around hinge, and latch hook 8 is fixedly connected with lock body 1 through spring 4; Spring 4 will make the free end of latch hook 8 away from lock body 1 according to that elasticity, in use, lock body 1 is fixedly connected with forms; This comes under the situation of pulling handle 2 not, and the mouth of hook of latch hook 8 will tighten compartment or its attached structure, thereby reality is locked the purpose of forms.
In order to make pulling handle 2 time and in 4 effect following times of spring, can there be a limit position of latch hook 8, is unlikely to damage; As a kind of preferred version, caging bolt 3 is fixedly connected with lock body 1, and lock handle spare is provided with limiting through hole 9; The part of caging bolt 3 stretches in the limiting through hole 9; Normal pot life position through hole 9 sizes are greater than caging bolt 3, thus the hole wall of limiting through hole 9 contact with caging bolt 3, when arriving the extreme position of setting; Their contacts can not further be rotated whole lock handle spare.Need to prove that limiting through hole 9 shapes should provide the contact surface that contacts with caging bolt 3 greatly to be advisable as much as possible.
With reference to Fig. 2, in order to realize the self-locking of lock construction, rotary locking cylinder 5 is hinged with lock body 1; Make that rotary locking cylinder 5 can serve as that axle rotates with its axis, it is orthogonal with lock body 1 with the hinged hinge of lock handle spare still that its rotating shaft also is parallel to horizontal direction, and an end of support bar 6 is fixedly connected with rotary locking cylinder 5; The other end is a free end, rotates along with the rotation of rotary locking cylinder 5 in the horizontal plane that support bar 6 can be vertical, and lock body 1 is provided with the groove of level; In groove, when turning to of support bar 6 was vertical, its free end contacted with lock handle spare when support bar 6 falls; Latch hook 8 can not be rotated, promptly can't pulling handle 2, thus real latch mechanism self-locking; For inordinate rotation not after making support bar 6 vertically, be provided with backstop bolt 7 in the lock body 1, particularly; Be provided with backstop bolt 7 in the groove, the axis of backstop bolt 7 and pavilion twist lock core 5 levels., support bar 6 just can not further rotate again when contacting with it.
As a kind of preferred version, in order to alleviate quality, the latch mechanism that is applicable to windows of railway vehicles of the utility model can adopt aluminum alloy materials to process.
The foregoing description does not limit the utility model in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in the protection domain of the utility model.
