Description

The button box device of silent door lock

Technical field

The utility model belongs to household five metals technical field, particularly relates to door lock, especially the button box device of door lock.

Background technology

Door lock is for keeping the space privacy to be installed in a kind of hardware on the door; Its basic structure comprises a lock box; Have the dead bolt that can carry out stretching motion under external force in the lock box, match, can prevent by fortuitous events such as winds and open with button box on being contained in doorframe.

In some special occasions, like ward etc., very high to the requirement that environment is quiet, the sound that the switch door is produced is enough to become noise source; For the noise of door and doorframe collision generation, people have found out many solutions, as adopting damp hinge, reach and at door and doorframe junction adhesive tape etc. are set.After this problem solved, the sound that sends of door lock just seemed considerably loud at closing time, makes us irritated.

The utility model content

The purpose of the utility model is to solve the noise problem that door lock sends in switching process, and a kind of button box device of silent door lock is provided.

The applicant in the noise that door lock sends, most importantly comes from the action of closing the door through careful discovering: when the door leaf motion, can bump with the button box panel when dead bolt is run into the button box on the doorframe; Dead bolt is released after getting into button box, can produce bump to the button box bottom.

Based on above analysis; The technical scheme that the utility model proposes is such: the button box device of silent door lock; Comprise and it is characterized in that button box body with cavity and the button box panel that places the button box body surface: also comprise the button box shell fragment, assemble fixing with button box body, button box panel three.

Further, described button box shell fragment is positioned at a lateral edges of contact dead bolt, and its end has the radian of outside turnup.

The utility model can have following several kinds of preferred schemes: button box panel and button box shell fragment riveted and fixed, and be connected through screw with the button box body.

The part of button box shell fragment places between button box panel and the button box body; Button box panel, button box shell fragment and button box body all have screw, thereby let the button box panel push down the button box shell fragment through screw.

The button box body has a containing cavity independently at its cavity edge, the rear portion of button box shell fragment has the installation sheet of a bending, and the relevant position of button box panel has the stator of a bending, and installation sheet and stator all insert in the containing cavity of button box body; Button box panel and button box body have screw, thereby through the fixing button box shell fragment of screw.

The utility model is provided with the button box shell fragment, and when door leaf moved, dead bolt at first touched the button box shell fragment, and the button box shell fragment will produce certain elastic deformation, cause buffering thus, can reduce the noise of bump; Button box shell fragment and button box body and button box panel fix, and can prolong its application life, guarantee the reliability of work; Wherein two kinds of preferred schemes need not be connected between button box shell fragment and button box panel, are that individual components is assembled through ingenious design fully, not only save cost, have practiced thrift the space yet.

Description of drawings

Below in conjunction with accompanying drawing the utility model is done further detailed description.

Fig. 1 is the structural representation of the utility model embodiment 1.

Fig. 2 is the structural representation of the utility model embodiment 2.

The specific embodiment

Embodiment 1

Referring to Fig. 1; Present embodiment comprises button box body 1, button box shell fragment 2, button box panel 3, screw 4; The button box body of present embodiment has two cavitys 11, and the part corresponding to cavity 11 on the button box shell fragment 2 has two through holes 21, and button box panel 3 also has two through holes 31 corresponding to cavity 11 places; One lateral edges 22 of button box shell fragment 2 stretches out outside button box body 1 and the button box panel 3, and downward-sloping and inside turnup.Button box body 1 two ends respectively have a screw 13; The centre of button box body 1 has a screw 14; The centre of button box shell fragment 2 has a screw 24, and the two ends of button box panel 3 respectively have a screw 33, and the centre of button box panel 3 has a screw 34; Screw 13, screw 33 are equipped with screw, and screw 14, screw 24, screw 34 are equipped with screw.

Embodiment 2

Referring to Fig. 2, present embodiment comprises button box body 1, button box shell fragment 2, button box panel 3, and the button box body of present embodiment has a cavity 11, and two ends respectively have a screw 12, and the lateral edge of cavity 11 has a rectangle containing cavity 13 independently; Button box shell fragment 2 is whole be L shaped basically, and the rear portion is an installation sheet 21 vertical with main body 23, and body front end edge 22 stretches out outside button box body 1 and the button box panel 3, and downward-sloping and inside turnup; Button box panel 3 has a through hole 31 corresponding to cavity 11 places, is getting stator 32 corresponding to the downward punching press in containing cavity 13 places, and the two ends of button box panel 3 respectively have a screw 33, and installation sheet 21 all inserts in the containing cavity 13 of button box body 1 with stator 32; Button box body 1 respectively has screw 12 and 33 with button box panel 3, through screw.

When door leaf moved, dead bolt at first touched button box shell fragment 2, and button box shell fragment 2 will produce certain elastic deformation, caused buffering thus, can reduce the noise of bump; Button box shell fragment 2 fixes with button box body 1 and button box panel 3, can prolong its application life, guarantees the reliability of work.And above-mentioned two kinds of schemes need not be connected between button box shell fragment and button box panel, are that individual components is assembled through ingenious design fully, not only save cost, have practiced thrift the space yet.
