Description
Technical field
The utility model relates to door lock fittings field, and more particularly, it relates to a kind of Telescopic device for lock bolt.
Background technology
Door lock is to keep room or individual storage space safety and a kind of hardware be arranged on door, its basic structure comprises the dead bolt that can be carried out stretching motion under external force, match with the button box be contained on doorframe, can prevent from being opened by under the fortuitous events such as wind.
Along with living standard improves, people also propose higher requirement to door lock safety, a kind of two bolt door lock is designed in order to meet above-mentioned requirements people, it mainly comprises housing and is arranged on the upper lock tongue in housing, lower dead bolt and transmission mechanism, but because the transmission mechanism in housing is also make with metal material usually, stretch out outside object or in indentation housing internal procedure at upper lock tongue, upper lock tongue all can all collide with transmission mechanism and the generation noise that rubs, and therefore remains to be further improved.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of Telescopic device for lock bolt, solve upper lock tongue stretch out in the outer or indentation housing internal procedure of object occur to clash into or friction produce noise problem.
For achieving the above object, the utility model provides following technical scheme:
A kind of Telescopic device for lock bolt, comprise housing, dead bolt slide plate and spring, the leading section of described dead bolt slide plate is connected with dead bolt, and end is provided with open portion thereafter; Described dead bolt slide plate is provided with installation groove, be installed with block in described housing, described block and spring are all placed in be installed in groove, and described spring is between block and open portion, one end of described block and spring is inconsistent, and the other end of spring is inconsistent with the cell wall installing groove.
The utility model is arranged further: described dead bolt slide plate is provided with the gathering sill arranged along dead bolt telescopic direction, is provided with the guide pad that to match with gathering sill in described housing.
The utility model is arranged further: described dead bolt slide plate is provided with and the installing hole installed groove and be connected, and described spring is placed in by installing hole and installs in groove, and the openend of described installing hole is provided with seal.
The utility model is arranged further: the leading section of described dead bolt slide plate is provided with front buffer part, and the rearward end of described dead bolt slide plate is provided with rear buffer part, and described front buffer part and rear buffer part are equipped with elastic component.
The utility model is arranged further: described elastic component is elastic caoutchouc or spring.
The utility model beneficial effect: at closing time, because upper lock tongue button box on doorframe matches, under magneticaction, dead bolt stretches out outside housing, dead bolt slide plate can be driven to travel forward simultaneously, dead bolt slide plate meeting Compress Spring, spring can produce reaction force, slow down dead bolt slide plate to travel forward speed, the open portion of dead bolt slide plate can not be collided with transmission mechanism, effective collision free produces noise, during enabling, dead bolt slide plate drives in dead bolt indentation housing moving backward, simultaneously prevent dead bolt slide plate to collide with transmission mechanism and to rub and produce noise not having to travel forward under External Force Acting in the elastic force effect of spring, effective solution upper lock tongue stretch out in the outer or indentation housing internal procedure of object occur to clash into or friction produce noise problem.

Detailed description of the invention
With reference to accompanying drawing 1 to Fig. 4, the utility model Telescopic device for lock bolt is described in further details.
A kind of Telescopic device for lock bolt, comprise housing 1, dead bolt slide plate 2 and spring 3, described housing 1 is provided with the lockhole worn for dead bolt, dead bolt slide plate 2 and spring 3 are all arranged in housing 1, described dead bolt slide plate 2 and housing 1 energy relative sliding, the leading section of described dead bolt slide plate 2 is connected with dead bolt, and end is provided with open portion 21 thereafter, and wherein open portion 21 and dead bolt slide plate 2 are wholely set, wherein said dead bolt slide plate 2 is provided with installs groove 22, block 4 is installed with in described housing 1, described block 4 and spring 3 are all placed in be installed in groove 22, described spring 3 is between block 4 and open portion 21, described block 4 is inconsistent with one end of spring 3, the other end of spring 3 is inconsistent with the cell wall installing groove 22, for the ease of mounting spring 3, described dead bolt slide plate 2 is provided with and the installing hole 23 installed groove 22 and be connected, described spring 3 is placed in by installing hole 23 to be installed in groove 22, the openend of described installing hole 23 is provided with seal 5, spring 3 is made to be placed on installation groove 22 so more firm, avoid departing from use procedure.
Described dead bolt slide plate 2 is provided with the gathering sill 24 arranged along dead bolt telescopic direction, is provided with the guide pad 6 that to match with gathering sill 24, when dead bolt slide plate 2 is seesawed in housing 1, offsets, play guide effect in described housing 1.
Wherein in order to avoid dead bolt slide plate 2 travels forward directly and housing 1 collides and produces noise, buffer part 25 before the leading section of described dead bolt slide plate 2 is provided with, in order to avoid the rearward end that dead bolt slide plate 2 moves directly backward and housing 1 collides and produces dead bolt slide plate 2 described in noise is provided with rear buffer part 26, described front buffer part 25 and rear buffer part 26 are equipped with elastic component, and described elastic component is elastic caoutchouc or spring 3.
