The specific embodiment

Shown in accompanying drawing 2 and accompanying drawing 3, be structure chart of the present utility model and location structure three-dimensional exploded view.As shown in the figure, the utility model comprise one can keep supplying, the lamellar body 2 of lower slider, an and elastic parts 3 that places this lamellar body 2.Wherein, this lamellar body 2 is provided with the teat 21(of suitable height in present embodiment in middle position, this teat 21 is made as narrower and the shape that the bottom is wider in top), the both sides of teat 21 are respectively equipped with the first holding section 22 and the second holding section 23 that generally is concave arc shape, make the linkage section of this teat 21 and the first holding section 22 and the second holding section 23 be made as circular-arc;

The root edge of this lamellar body 2 is provided with a fixed leg 24 to the downward-extension suitable length, and is respectively equipped with reference column 25,26 in the upper and lower surface of lamellar body 2;

This elastic parts 3 is nested in the fixed leg 24 of lamellar body 2, is the spring of a suitable length;

By the combination of aforementioned components, consist of the location structure of lockset.This lamellar body 2 is placed the below of the handle rotating shaft 11 of lockset 1, make reference column 25,26 be arranged in respectively the set chute 14,15 of lockset 1 casing, and elastic parts 3 placed the set locating slot of casing 16, make handle rotating shaft 11 when rotating unlatching lockset 1, teat 21 by lamellar body 2 is sticked in the breach 111 of handle rotating shaft 11 to consist of the location, thereby the state that lockset 1 is held open is to avoid because of the of short duration puzzlement that can't enter with key of going out.

As shown in Figure 4, implement illustration for breakdown action of the present utility model.As shown in the figure, when the utility model needs of short duration going out as the user, handle is rotated, and then handle rotating shaft 11 is rotated with drivening rod 12 pulling dead bolts 13, when handle rotating shaft 11 is rotated, because it is circular-arc that the teat 21 of lamellar body 2 is made as, and be positioned post 25,26 of lamellar body 2 is spacing, so this lamellar body 2 will be pressed down and move down by handle rotating shaft 11.

As shown in Figure 5, implement illustration for location action of the present utility model.As shown in the figure, the utility model is after handle rotating shaft 11 continues to rotate, dead bolt 13 is in the retraction lockset 1, to consist of opening, and after the side of handle rotating shaft 11 passes through lamellar body 2, lamellar body 2 will move up because of the elasticity of elastic parts 3, and then make its teat 21 be sticked in the breach 111 of handle rotating shaft 11, and be sticked in handle rotating shaft 11 both sides by lamellar body 2 first holding sections 22 and the second holding section 23, and because the linkage section of teat 21 and the first holding section 22 and the second holding section 23 is made as circular-arc, make handle rotating shaft 11 consist of accurately location, dead bolt 13 keeps the opening that inside contracts, to avoid because of the of short duration puzzlement that can't enter with key of going out.

As shown in Figure 6, implement illustration for closing motion of the present utility model.As shown in the figure, the utility model when the user after entering, only need the handle backward rotation, and then make connecting rod 12 reply the location, dead bolt 13 is pushed out of outside the lockset 1 state of closing with formation.When handle rotating shaft 11 was rotated, because that the teat 21 of lamellar body 2 is made as is circular-arc, and be positioned post 25,26 of lamellar body 2 was spacing, so this lamellar body 2 will press down and move down by handle rotating shaft 11, held by the elasticity of elastic parts 3 and upwards replied the location.

Aforementioned location structure of the present utility model can go out to keep outside the unlatching of lockset for of short duration, when going out to lock a door for a long time, handle can be rotated in the opposite direction, but same drivening rod 12 and then drive dead bolt 13 are opened lockset, and this handle rotating shaft 11 is namely reversed and is replied the location after handle is released out, dead bolt 13 is released is closed condition, as the unlatching of lockset and the action of autoshutdown, and be not subjected to the impact of location structure.
