The purpose of this utility model is to be achieved through the following technical solutions:
A kind of dumb waiter side opening door lock, comprises base, and the right side on described base is provided with electromagnet, and the left side of described electromagnet is provided with electromagnet mandrel, and the left end of described electromagnet mandrel is connected with support arm, and the left end of described support arm is connected with secondary support arm; The below of described secondary support arm is from left to right connected with switch movable contact in turn, door draws plug and small rack, the bottom of described small rack is connected on base, described door draws plug to be positioned at the knock hole on base, the below of described switch movable contact is provided with switch and determines contact, the side that described switch is determined contact is provided with gate interlock support, and the bottom of described gate interlock support is connected on base.
Further, described electromagnet mandrel is provided with electromagnet reseting pressuring spring.
Further, described small rack is connected to the lower right corner of secondary support arm, and described support arm is connected to the upper right corner of secondary support arm.
Further, described secondary support arm draws plug, small rack, support arm with door, between support arm and electromagnet mandrel, is and rotarys connection.
Further, described switch is determined contact and switch movable contact cooperatively interacts.
The beneficial effects of the utility model are: simple in structure, and make mechanical lock and electrical equipment validation switch realize interlock, avoided mechanical lock and the nonsynchronous situation of electrical equipment validation switch, the safety that has improved dumb waiter door lock.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is one of structural representation of a kind of dumb waiter side opening door lock described in the utility model embodiment;
Fig. 2 be a kind of dumb waiter side opening door lock described in the utility model embodiment structural representation two.
In figure:
1, base; 2, small rack; 3, switch movable contact; 4, electromagnet; 5, electromagnet mandrel; 6, secondary support arm; 7, support arm; 8, switch is determined contact; 9, gate interlock support; 10, door draws plug; 11, electromagnet reseting pressuring spring.
The specific embodiment
As shown in Figure 1-2, a kind of dumb waiter side opening door lock described in the utility model embodiment, comprise base 1, right side on described base 1 is provided with electromagnet 4, the left side of described electromagnet 4 is provided with electromagnet mandrel 5, the left end of described electromagnet mandrel 5 is connected with support arm 7, and the left end of described support arm 7 is connected with secondary support arm 6; The below of described secondary support arm 6 is from left to right connected with switch movable contact 3 in turn, door draws plug 10 and small rack 2, the bottom of described small rack 2 is connected on base 1, described door draws plug 10 to be positioned at the knock hole on base, the below of described switch movable contact 3 is provided with switch and determines contact 8, the side that described switch is determined contact 8 is provided with gate interlock support 9, and the bottom of described gate interlock support 9 is connected on base 1.Described electromagnet mandrel 5 is provided with electromagnet reseting pressuring spring 11.
Described small rack 2 is connected to the lower right corner of secondary support arm 6, and described support arm 7 is connected to the upper right corner of secondary support arm 6.Described secondary support arm 6 draws plug 10, small rack 2, support arm 7 with door, between support arm 7 and electromagnet mandrel 5, is and rotarys connection.Described switch is determined contact 8 and is cooperatively interacted with switch movable contact 3.
During installation, door draws the bottom of plug 10 to be positioned at the lockhole on side opening door, and door draws plug 10 under Action of Gravity Field, to slip in lockhole.Manually triangulation chain is positioned at the lower left corner of secondary support arm 6, for manually stirring secondary support arm 6.
The principle of work of the dumb waiter side opening door lock described in the utility model embodiment:
1) automatically control, during electromagnet 4 energising action, electromagnet mandrel 5 shrinks, and drives support arm 7 and secondary support arm 6 clickwises, makes door draw plug 10 to leave lockhole, and mechanical lock is opened; Simultaneous Switching moving contact 3 leaves switch and determines contact 8, switch circuit breaking.
2) manually control, in the Room, stir secondary support arm 6 lower left quarters outdoors by triangulation chain, secondary support arm 6 cws are turned, door draws plug 10 to leave lockhole, and mechanical lock is opened; Simultaneous Switching moving contact 3 leaves switch and determines contact 8, switch circuit breaking.
When electromagnet reseting pressuring spring 11 lost efficacy, secondary support arm 6 falls under the effect of gravity, and door draws plug 10 automatically to insert in lockhole, realizes locking.Simultaneous Switching moving contact 3 is inserted into switch to be determined in contact 8, switch energising.Thereby the safety and stablization of elevator have been guaranteed.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection domain of the present utility model.
