Description
Technical field
The utility model relates to a kind of door lock, is specifically related to EMU dustbin door lock.
Background technology
EMU often saves compartment and be provided with dustbin, when dustbin is filled, need to change the refuse bag in it.If dustbin does not arrange door lock, causing high vibration or other fortuitous events to spread out causing the rubbish in it once there is snub, affecting health and safety in car.
Along with train continuous speed-raising to 200 kilometer, 300 kilometers even higher, motor train unit interior decoration requires attractive in appearance, light and sound construction, long service life, and maintenance easily, therefore lockset is with toilet door structure and environment for use thereof and require to mate, and just proposes new requirement to how to design.
Summary of the invention
In order to overcome the above problems, the purpose of this utility model is to provide novel EMU dustbin door lock.
EMU dustbin door lock described in the utility model comprises lock body, knob handle, lock core, dead bolt; Wherein lock body is circular cylinder, and its end is provided with semi-circular flange; Knob is being divided into main body and labour contractor's two parts, main body likeness in form spheroid, spheroid proximal portion is provided with path sector grooves, labour contractor is semi-circular, be connected with a face of groove, labour contractor is buckled in lock body end without flange place, and main body is positioned at lock body inside, main body bottom is provided with groove, and lock core top to be placed in groove and to be connected by rotating shaft; Lock core afterbody is fixed with dead bolt.
Knob forms the attacker of door lock the fan groove of main body, when suction garbage can door opened by needs, first this attacker is pressed, the labour contractor of knob handle just tilts from lock body end, labour contractor is now caught to rotate, the lock core be attached thereto also rotates thereupon, thus the dead bolt be fixed on lock core also rotates, and suction garbage can door is opened; When needing locking, will rotate labour contractor and reversely rotate, lock core drives dead bolt to return back to origin-location.
EMU dustbin door lock described in the utility model, is arranged on dustbin wallboard, simple, frivolous, accurate and compact, at ordinary times not used time, and attacker is attached on wallboard completely, facilitates attractive in appearance; During use, twisting attacker, dead bolt rotates, and suction garbage can door is opened, and rubbish can be taken out or change.Even if operationally speed up to 200 kilometers even 300 kilometers when, still the state of silent, structural safety can be kept, and all parts are demountable structure, long service life, convenience easy to maintenance, meet the service requirement of high speed motor car completely, provide guarantee also to the safety of passenger.
In order to reach better effect, the utility model can also in the following ways:
1, knob has torsion spring the rotating shaft be connected with lock core is overlapped.Two torque arm of torsion spring are stuck in knob handle and lock core, its role is to attacker's tension force, make it to keep balance when not using lockset, rebound when torsion lockset.
2, lock core is provided with the boss isometrical with lock body, and boss is positioned at lock body bottom, and boss bottom surface is circumferentially provided with spacing preiection, and cover on lock core corresponding with it has and stops iron with male cooperation, and dead bolt is pressed in only on iron.Like this restriction is played to the rotational angle of lock core and then dead bolt, to control unlatching and the locking of the preparation of dead bolt opposite house.
3, the fixed form of described dead bolt and lock core is: lock core trailing exterior surface is provided with screw thread, and pad and nut are installed in the position that lock core is positioned at outside dead bolt at it, and lock core is positioned at outside nut and is provided with cottor pin.The installation of such convenient door lock, dismounting and maintenance.
4, described lock body external surface is provided with screw thread, and nut is threaded connection with it.Like this when installing this door lock, according to door-plate thickness adjusting nut, thus the object of fixing door lock can be reached.
5, described nut is provided with through hole.Thus nut is fixed by screw when installing door lock, make the fixing more firm of door lock.
6, EMU dustbin door lock described in the utility model also comprises stopper plate, is fixed in adjacent wall board, mates with dead bolt.Thus reduce the friction of dead bolt and dustbin wallboard and make the contact of dead bolt and wallboard tightr.
7, described knob is provided with decorative pattern middle sector grooves face.The frictional force pressed when scratching hand can be increased like this, thus facilitate attacker to tilt.

Detailed description of the invention
Composition graphs 1 is described in detail to EMU suction garbage can door lock described in the utility model.
As shown in Figure 1, EMU dustbin door lock is divided into following components:
Lock body 4, be circular cylinder, its end is provided with semi-circular flange.
Knob, 5, is divided into main body and labour contractor's two parts, main body likeness in form spheroid, and spheroid proximal portion is provided with path sector grooves, and a face of groove is horizontal direction, and together with being linked as with semi-circular labour contractor, another face is provided with decorative pattern to facilitate pressing; Labour contractor is buckled in lock body 4 end without flange place, mutually mates formation domain shape thus with lock body 4 end semi-circular flange; It is inner that main body is positioned at lock body 4, and with lock body 4 matched in clearance, can rotate in lock body 4, its bottom is provided with groove, in order to coordinate with lock core 2 again.
Lock core 2, top has U-lag, and U-type groove is placed in knob in the groove of 5 bottoms, and the two is connected by rotating shaft 6, and lock core 2 can rotate 6 along rotating shaft 6 relative to knob; In rotating shaft 6, cover has torsion spring 7, and two torque arm of torsion spring 7 are stuck in knob 5 with on lock core 2, and the setting of torsion spring 7 is convenient to knob the automatic homing of 5.Lock core 2 is provided with the boss isometrical with lock body 4, and boss is positioned at lock body 4 bottom, thus lock body 4 is relatively airtight, protection inner components; Boss bottom surface is circumferentially provided with two banded spacing preiections.
Only iron 8, its center has square hole, is enclosed within lock core 2, and lock core 2 relevant position is also square, thus only iron 8 is located in circumference; Only iron 8 edge shape matches with spacing preiection, the angle of the two two close plane is 90 degree, therefore when lock core 2 during 90-degree rotation, stops iron 8 and touches with spacing preiection in lock body 4, so lock core 4 stops the rotation, and then control more accurate to the unlatching of door lock and locking states.
Dead bolt 3, is fixed on lock core 2 afterbody, is positioned at and stops outside iron 8, lock core 2 trailing exterior surface is provided with screw thread, lock core 2 is located at dead bolt 3 outside at it and installs packing ring 10 and primary nut 11, and lock core 2 is positioned at outside primary nut 11 and is provided with cottor pin 13, and cottor pin 13 is arranged in the through hole of lock core 2 radial direction.
Described lock body 4 external surface is provided with screw thread, and big nut 9 is threaded connection with it, when installing this door lock, can regulate big nut 9, thus reach the object of fixing door lock according to door-plate thickness; Big nut 9 is provided with through hole, is fixed by screw 12 pairs of big nuts 9, makes the fixing more firm of door lock.
Stopper plate 1 is arranged on the adjacent dustbin wallboard of dustbin, matches with dead bolt 3, and when dustbin is at locking states, dead bolt 3 is pressed on stopper plate 1, reduces the friction of dead bolt 3 and dustbin wallboard and makes dead bolt 3 tightr with the contact of wallboard.
