Abstract
The utility model discloses a safe lock with logic function, including interior handle, outer handle, breech lock and fixed block, install the shifter on the fixed block, the shifter passes through pull rod I, pull rod II and pull rod III and connects interior handle, outer handle and breech lock respectively, still install the motor drive ware on the fixed block, the motor drive ware sets up in the shifter below to make the push rod in the motor drive ware can support the shifter rotation when stretching out, the motor drive ware passes through the wire and connects the sensor. The utility model discloses novel structure, safe and reliable when high altitude construction, adopt this lock can make the hatch door locking, and inside and outside handle all can not be opened moreover, and when the lower was fallen to the hatch door, the hatch door can freely open the door through inside and outside handle, and passenger or the personal safety of operation personnel when high altitude construction have been ensured to this kind of lock, have satisfied advantages such as various high altitude construction fields vehicle -mounted lift driver's cabin or work platform guardrail security needs.
Description
Technical field
The utility model relates to door lock, is specifically related to a kind of safety door latch with logic function, for work high above the ground lifting control cab or job platform guardrail safety locking.
Background technology
There is certain potential safety hazard in work high above the ground, when opening the door in operation bucket, high-altitude application room, personnel easily step on sky, easy generation accident, be badly in need of a kind of door lock with logic control function, be in locking states under operating mode is just hidden in high-altitude always, normally door lock can be opened, not by the impact of high-altitude locking when low level.
Summary of the invention
According to the deficiencies in the prior art, provide a kind of have novel structure, safe and reliable, meet the safety door latch of various field of aerial work with advantages such as car lifting control cab or job platform guardrail security needs.
The utility model realizes by following technical scheme:
A kind of safety door latch with logic function, comprise Internal handle, outer handle, breech lock and fixed block, described fixed block is provided with switching mechanism, described switching mechanism is connected Internal handle, outer handle and breech lock respectively by pull bar I, pull bar II and pull bar III, described fixed block is also provided with motor driver, described motor driver is arranged on below switching mechanism, props up switching mechanism rotate to enable the push rod in motor driver when stretching out; Described motor driver is by wire connecting sensor.
Described sensor adopts proximity switch.
The model of described proximity switch is LS43M41D11.
The utility model beneficial effect:
The utility model novel structure, safe and reliable, when work high above the ground, adopt this door lock can make hatch door locking, and inside and outside handle all can not be opened, when hatch door falls lower, hatch door freely can be opened the door by inside and outside handle, and this door lock ensure that occupant or the personal safety of operating personnel when work high above the ground, meets various field of aerial work with advantages such as car lifting control cab or job platform guardrail security needs.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation:
1-Internal handle, 2-fixed block, 3-outer handle, 4-breech lock, 5-bump bolt, 6-wire, 7-switching mechanism, 8-motor driver, 8-1-push rod, 9-sensor, 10-pull bar I, 11-pull bar II, 12-pull bar III, 13-door, 14-hinge.
Detailed description of the invention
Below in conjunction with accompanying drawing, by specific embodiment, technical solutions of the utility model are described further.
As shown in Figure 1, a kind of safety door latch with logic function, is separately installed with Internal handle 1 and outer handle 3 on the top of door 13, the middle part of door 13 has been bolted to connection fixed block 2, fixed block 2 is provided with switching mechanism 7, the side of door 13 is provided with breech lock 4, and opposite side is provided with hinge 14; Switching mechanism 7 is connected Internal handle 1, outer handle 3 and breech lock 4 by pull bar I 10, pull bar II 11 respectively with pull bar III 12; By pulling Internal handle 1 or outer handle 3 to be with manual converting mechanism 7 to rotate, thus pull pull bar III 12, pull bar III 12 pulls bump bolt 5 indentation in breech lock 4, thus realizes opening of door 13; With elasticity reset device in switching mechanism 7, when not pulling Internal handle 1 or outer handle 3, switching mechanism 7 can reset again, thus the bump bolt 5 in breech lock 4 can be stretched out again, thus realizes the locking of door 13; Motor driver 8 is installed below switching mechanism 7, push rod 8-1 in motor driver 8 can prop up switching mechanism 7 and rotate when stretching out, motor driver 8 is by wire 6 connecting sensor 9, sensor 9 adopts proximity switch, the model of proximity switch is LS43M41D11, proximity switch is arranged in frame, whether is in low level for perception operation bucket.
The utility model principle is: by the given motor driver 8 of external signal, guarantee that the push rod 8-1 in motor driver 8 stretches out or retracts, when aerial work platform or driver's cabin leave ground, given motor driver 8 one signals of telecommunication, push rod 8-1 in motor driver 8 stretches out, carry out spacing to the switching mechanism 7 of door lock, at this moment all can not open door lock by Internal handle 1 and outer handle 3; When aerial work platform or driver's cabin are near ground, given motor driver 8 one signals of telecommunication, the push rod 8-1 in motor driver 8 retracts, and that removes the switching mechanism 7 of door lock is spacing, at this moment all can open door lock by Internal handle 1 and outer handle 3.
During use, when operation bucket is in low level, sensor 9 is in off-state, motor driver 8 is controlled by wire 10, make push rod 8-1 be in shortening state, do not affect the motion that breech lock 4 is opened in switching mechanism 7, now Internal handle 1 and outer handle 3 all can open breech lock 4;
When operation bucket leaves low level, sensor 9 is in open mode, controls motor driver 8 by wire 10, makes push rod 8-1 be in elongation state, props up the motion of switching mechanism 7, thus makes Internal handle 1 and outer handle 3 all can not open breech lock 4.
The present invention due to adopt said structure, have novel structure, safe and reliable, meet various field of aerial work with advantages such as car lifting control cab or job platform guardrail security needs.
