Abstract
The utility model relates to a magnetic force door lock, the aim of which is to overcome the influence of the external strong force to the magnetic force door lock. The utility model provides a magnetic force door lock with a safety door bolt device, which is characterized in that the safety door bolt device is composed of a fixed seat, a bolt, a spring, a driving arm and a thimble, wherein the fixed seat is arranged on a continuing iron plate, a bolt positioning hole and a thimble positioning hole are arranged at the front face, a pin positioning hole is arranged at the side face, and a groove is arranged in the middle. A shaft hole is arranged in the middle of the driving arm which is movably positioned in the fixed seat by the pin. The magnetic force door lock with a safety door bolt device has the advantage that the utility model can effectively avoid the intrusion of the external force because of the action of the bolt.
Description
The utility model relates to a kind of magnetic door lock.
In the prior art, a kind of magnetic force door is arranged as shown in Figure 1: this magnetic door lock is made of the iron device that continues that is installed on the Magnetic lock head 1 on the doorframe and be installed on the door leaf, and the described iron device that continues is made of continue iron plate 2, the iron plate holder 3 that continues, spring 4 and the iron plate positioning bolt 5 that continues of activity.When door is closed, touch the microswitch on the doorframe, electric power starting at this moment, activity continues iron plate by adhesive.The advantage of this magnetic force lock be can overcome doorframe with between the space to the influence of magnetic force.But under extraneous powerful effect, can influence safety.
The purpose of the utility model is in order to overcome extraneous powerful influence to magnetic door lock, a kind of magnetic door lock that has the safety door pin assembly to be provided.
The utility model is achieved in that a kind of magnetic door lock that has the safety door pin assembly, be made of continue iron plate 2, the iron plate holder 3 that continues, spring 4 and continue iron plate positioning bolt 5 and safety door pin assembly of Magnetic lock head 1, activity, it is characterized in that: described safety door pin assembly is made of holder 6, latch 7, spring 8, transmission arm 9 and thimble 10; Holder 6 is installed on the iron plate 2 of continuing, and its front is provided with the locating hole 11 of at least one latch 7 and the locating hole 12 of a thimble 10, and its side is provided with the locating hole (not shown) of pin 13, is provided with one in the middle of it for the groove 15 of transmission arm is installed; Be provided with axis holes 14 in the middle of the described transmission arm 9, pin 13 pass locating hole on this axis hole 14 and the holder 6 with transmission arm 9 activity orientation in holder 6; Transmission arm 9 one ends and thimble 10 tail ends flexibly connect, and the other end is conflicted with latch 7 and is connected.
Described thimble 10 tail ends and transmission arm 9 flexibly connect by pin 16.
Described Magnetic lock head 1 is provided with the jack 17 that cooperates with latch.
The effect of latch the utility model has the advantages that: owing to can prevent the invasion of external force effectively.
Now in conjunction with the accompanying drawings and embodiments the utility model is described as follows:
Fig. 1: be the structural representation of existing magnetic door lock;
Fig. 2: be the schematic appearance of existing magnetic door lock;
Fig. 3: be the safety door pin assembly off working state structural representation of magnetic door lock;
Fig. 4: be the safety door pin assembly working state structure schematic diagram of magnetic door lock;
Most preferred embodiment of the present utility model is: be made of continue iron plate 2, the iron plate holder 3 that continues, spring 4 and continue iron plate positioning bolt 5 and safety door pin assembly of Magnetic lock head 1, activity.Described safety door pin assembly is made of holder 6, latch 7, spring 8, transmission arm 9 and thimble 10.Holder 6 is installed on the iron plate 2 of continuing, and its front is provided with the locating hole 11 of two latches 7 and the locating hole 12 of thimble 10, and the side of holder 6 is provided with the locating hole 14 of pin 13, and the centre is provided with one for the groove 15 of transmission arm 9 is installed; In the locating hole 14 of holder 6, this application point is the fulcrum of transmission arm 9 by pin 13 activity orientation at described transmission arm 9 middle parts.Described transmission arm 9 one ends flexibly connect by pin 16 and thimble 10, and this application point is the force of transmission mechanism; The other end of described transmission arm 9 is connected with the contact of latch 7 bottoms, and this application point is the moving point of transmission arm.Fulcrum to the distance in force is 1: 4 with the ratio that fulcrum extremely moves the distance of point.
Embodiment of the present utility model and existing magnetic door lock are used.Magnetic lock head 1 is installed on doorframe, and the activity iron plate 2 of continuing is installed on door leaf, and both position correspondences can be installed on the upper end of door, also can be installed on the bottom of door or vertically be installed in the side of door.When door is closed, the microswitch closure, electric power starting, activity continues iron plate 2 by adhesive, on the at this moment movable iron plate 2 of continuing, the thimble 10 of safety door pin assembly is pressed by Magnetic lock head 1, under the effect of transmission arm 9, latch 7 is by jack-up and insert jack mouth 17 on the Magnetic lock head 1, and it also is 1: 4 that the distance of the distance of thimble motion and latch motion equals the ratio of fulcrum to the distance in force and fulcrum to the distance of moving point.When magnetic door lock was worked, if any the brute force invasion, doorframe may produce parallel moving with door leaf.At this moment latch plays booster action.Otherwise magnetic force is opened, and promptly power supply is cut off, and the activity iron plate 2 of continuing resets under the effect of spring 4, and latch 7 is packed up automatically, and door leaf can be opened.
As everyone knows, embodiment of the present utility model is a kind of exemplary and non-limiting, for example substitutes as the also available gear of the transmission arm 9 of present embodiment.Similarly transmission device all can reach the purpose of the relative motion of thimble and latch, therefore all belongs to protection domain of the present utility model.
