The specific embodiment

Below in conjunction with accompanying drawing and the specific embodiment the utility model is further described.

Among the embodiment as shown in Figure 1, a kind of elevator inlay door locking device, comprise the dead bolt 3 on the doorframe 2 that is arranged on layer door 1, and be arranged on the layer door 1 and cooperate with dead bolt in order to pin the snap close 4 of layer, comprising also that a door lock puts in place detects the loop, and the door lock of the bolt-type that is associated with the action of the dead bolt detector switch 5 that puts in place, this door lock detector switch that puts in place is serially connected in door lock and puts in place and detect in the loop, like this when the normal locking of layer door, dead bolt enters into when snap close is interior lives layer door lock, the door lock closed conducting of detector switch that puts in place, door lock puts in place and detects the loop and can confirm that door lock of elevator is working properly, and car can normal lifting; And if layer door is non-latching or dead bolt does not enter in the snap close when layer door lock lived fully, the door lock detector switch open circuit that puts in place, door lock put in place and detect the loop can to confirm that door lock of elevator occurs unusual, and car can't start, thereby can guarantee the safety of elevator operation.

For the mode of operation to door lock of elevator when the Elevator landing detects, the action of dead bolt need be undertaken by automatically controlled mode, so that when Elevator landing, door lock of elevator can be opened or lock easily.Wherein comparatively simple automatically controlled mode as shown in Figure 1, it comprises one from the electromagnet 6 of homing position type, dead bolt 3 is made L shaped fork, one end of dead bolt bending is for going deep into the latch hook 31 in the snap close, and the centre of dead bolt is provided with rotating shaft 32, thereby can be around the shaft swing of centre, rotating shaft at dead bolt simultaneously arranges the torsion spring (not shown), dead bolt is under the effect of torsion spring, and the latch hook of one end is positioned at snap close, in order to make layer door all be in locking state in most of times.The other end of dead bolt then constitutes connecting rod mechanisms by a connecting rod 62 and iron core 61 from the electromagnet of homing position type, be understandable that, connecting rod and dead bolt and iron core are hinged, like this, when needs open the door, the electromagnet energising makes the iron core action, and drives the elastic force rotation that fork overcomes torsion spring by connecting rod, and latch hook is separated with snap close.Need to prove, L shaped dead bolt needs approximate horizontal ground to arrange, and its rotating shaft should be greater than the distance that is connected with connecting rod between the end with the distance between latch hook one end, like this, even if the latch hook of dead bolt one end does not have torsion spring can rely on the weight of self to enter in the snap close automatically yet, improving the reliability of door lock of elevator, and can reduce the iron core shift motion of electromagnet, be conducive to reduce the manufacturing cost of electromagnet.Certainly, for the ease of resetting of dead bolt, we can arrange a domatic projection 11 that progressively raises at layer door, and snap close is arranged on the middle highest point of domatic projection, electromagnetism is fallen at layer door open power-off restoration when putting in place, also synchronous reset of dead bolt then is when layer door is closed, dead bolt can enter in the snap close automatically along the domatic projection, thereby can avoid the long-time energising of electromagnet.In addition, for ease of when having a power failure or other emergency situation occurring, opening layer door, we can automatically reset turning cylinder 81 in the doorframe one side setting of layer door, the outer end of turning cylinder arranges regular triangular prism shaped coupling end, while sheathed handle 82 on coupling end, the inner of turning cylinder then arranges driving lever 83 radially, and the end of driving lever is associated with dead bolt by brake flexible axle 84, like this, can drive the dead bolt action to open the door by force by handle and brake flexible axle.Be understandable that, the sheath in the brake flexible axle outside need be fixed with the end that driving lever is connected with dead bolt, and inner steel wire one end is connected with the end of driving lever, the other end is connected the tail end that latch hook is connected with fork, arrange at turning cylinder simultaneously and promote the torsion spring that driving lever resets and rotates, and handle takes off at ordinary times and deposits, like this, the brake flexible axle does not produce pulling force to dead bolt at ordinary times, so that dead bolt can automatically reset.

Certainly, the automatically controlled of dead bolt also can be realized by mechanism as shown in Figure 3: the doorframe at layer door arranges chute 71, dead bolt is then made the latch of direct rod shape, and dead bolt is slidingly connected in the chute, the rear end that dead bolt is positioned at chute arranges stage clip 72, so that the promotion dead bolt, being located at the outer front end of chute can enter in the snap close.In addition, we also need at the doorframe of layer door a cam 73 that is driven by stepping motor 74 to be set, along the circumferential direction be interval with some juts 731 and lower concave part 732 on the cam equally spacedly, preferred value is two juts and two lower concave parts, and the side at dead bolt radially arranges push rod 33, push rod is close to the periphery of cam under the thrust of stage clip, thereby when push rod is resisted against the lower concave part of cam, dead bolt is under stage clip promotes, and its front end is deep in the snap close and is in locked position; And need open the door the time, the control center of elevator control cam rotates, and makes push rod be resisted against the jut of cam, and cam promoted push rod and the front end of dead bolt retreated leave snap close this moment, and dead bolt is in the unlocked position.Further, can connect worm screw 75 on the motor shaft of stepping motor, correspondingly, a turbine 76 with worm mesh is set on cam coaxially, thereby make stepping motor pass through the Worm and worm-wheel gearing power cam.Worm and worm-wheel gearing has bigger transmitting ratio, thereby can reduce the moment of torsion of stepping motor, simultaneously, the auto-lock function of stepping motor self, and turbine and worm transmission device failure-free self-locking action, can guarantee cam position accurately and reliably, avoid it under power down mode, freely to rotate.Be understandable that the dead bolt in this programme should be preferably the top that vertically is arranged in snap close, like this, dead bolt also can rely on the weight of self to move down and enter in the snap close even without the thrust of stage clip.With the similar ground of aforesaid scheme, for ease of when having a power failure or other emergency situation occurring, opening layer door, we can automatically reset turning cylinder in the doorframe one side setting of layer door, the outer end of turning cylinder arranges leg-of-mutton coupling end, while sheathed handle on coupling end, the inner of turning cylinder then arranges driving lever radially, and the end of driving lever is associated with dead bolt by the brake flexible axle, like this, can drive the dead bolt action to open the door by force by handle and brake flexible axle.Be understandable that, the sheath in the brake flexible axle outside need be fixed with the end that driving lever is connected with dead bolt, and inner steel wire one end is connected with the end of driving lever, the other end passes stage clip and is connected with the rear end that dead bolt is positioned at chute, arrange at turning cylinder simultaneously and promote the torsion spring that driving lever resets and rotates, and handle takes off at ordinary times and deposits, like this, the brake flexible axle does not produce pulling force to dead bolt at ordinary times, so that dead bolt can automatically reset.

In addition, as shown in Figure 2, the door lock detector switch 5 that puts in place is made of the elastic clip 52 that is arranged on the plug 51 on the dead bolt and be arranged in the snap close, and insulate between plug and the dead bolt, insulate between elastic clip and the snap close, elastic clip can the clamping plug, is communicated with in order to make between the two.In order reasonably to arrange plug, we need arrange groove 34 at the end face of dead bolt, then plug are arranged in the groove of dead bolt end face, can protect plug well like this, avoid being broken.

Plug can be by having excellent conductive performance and elastomeric bryllium bronze copper sheet is made, bending in the middle of the copper sheet, make plug be wedge shape, the place, tip that the two side of plug connects is provided with knuckle, and the two side of plug is the cambered surface of evagination, its radius is the 50-80 millimeter, preferred value is 65 millimeters, like this, increased on the one hand the compressive strength of lateral wall, be understandable that simultaneously, can push when pressurized is recessed somewhere remainder rises outward as same water-filled sack, lateral wall can be pushed the remainder evagination of lateral wall when pressurized is recessed somewhere, thereby plug is contacted reliably with elastic clip.In addition, reciprocating and turning-back also can be set in the cavity between the two side of plug be flexuose bracing frame 511, bracing frame can adopt the bryllium bronze copper sheet to make equally, and the place of turning back of bracing frame both sides is resisted against respectively on the madial wall of plug both sides.Reciprocating and turning-back is flexuose bracing frame and is equivalent to the combination side by side that a plurality of A fonts that are made of two supporting blades support, when the pressurized of certain turning point, the supporting blade of its both sides can outwards open and push remaining supporting blade of both sides, thereby have good buffering effect and Flexible Reset, plug can appropriateness be out of shape when being squeezed, and pressure can resile after removing fully, can contact reliably but make between the plug elastic clip, and can greatly prolong its service life, improve reliability during operation.

Further, the groove of dead bolt end face has the locking sidewall 341 of two symmetric arrangement, and the locking sidewall is from outside to inside gradually to intermediate, inclined; Correspondingly, elastic clip then is bent into M shape by copper sheet, the recess formation of dwindling downwards gradually in the middle of it is held the also holding part 521 of clamping plug, and outside two side tilts laterally, its angle of inclination is than the little 3-5 degree in the angle of inclination of the locking sidewall of groove, preferred value is 4 degree, and the root of both sides external wall is connected in the snap close.Like this, in the time of in dead bolt enters into snap close, plug synchronously enters in the holding part, two locking sidewalls of groove are then pushed two lateral walls of elastic clip, lateral wall is drawn close to the center, thereby two sidewalls and the plug of pushing holding part fit tightly, and make plug contact conducting reliably with elastic clip.Certainly, for the ease of making and installing, the root of elastic clip both sides external wall can be fixed on the adapter plate 522, and then adapter plate is fixed in the snap close.Because the opening of holding part is big, the bottom is little, thereby is convenient to entering of plug, and simultaneously, the opening annulus 523 that constitutes by an one bending between the two side of holding part bottom is connected, and the central angle of opening annulus correspondence can be at 270 degree between 300 degree.Structure similar ground, two side with plug, the two side of elastic clip outside is the cambered surface to the both sides evagination, and similarly, the two side of holding part then is the cambered surface to the center evagination of holding part, the radius of interior lateral wall cambered surface is the 50-80 millimeter, and its preferred value is 65 millimeters.In addition, be understandable that, the two side of holding part should be less than the distance of plug two side at small end in the distance of small end, when entering in the holding part of elastic clip fully with convenient plug, the two side of holding part can be subjected to the extruding of plug and be out of shape and open, the opening annulus plays the effect of similar jump ring, thereby clamping plug closely, the outside outward-dipping lateral wall of elastic clip then plays the resilient mounting effect to the big end of holding part opening, make holding part from small end to big end with the tight clamping of plug.Because the big end of holding part opens distortion than small end is easier, so the angle of inclination of holding part two side can be arranged to the angle of inclination less than the plug two side.

The utility model puts in place and detects the loop by put in place detector switch and corresponding door lock of a door lock that is associated with dead bolt is set, put in place to judge whether dead bolt moves, when layer Men Wei close or dead bolt because a variety of causes action is not in place, when layer Men Wei is locked, door lock puts in place and detects the loop and can detect the door lock detector switch that puts in place and be in open-circuit condition, thereby the control lift car keeps quiescence; Have only when dead bolt action puts in place, make the door lock detector switch that puts in place be in closed conducting state, door lock puts in place and detects the loop and can judge that layer door is locked, thus this moment lift car normally the lifting operation can guarantee the safety that elevator moves.
