Adopt the door lock of this technical scheme, opening at closing time, dead bolt contacts with the convex surface of snap close, when having only power on acting on door enough big, the snap close convex surface is enough to make dead bolt to overcome the interior power of spring tension indentation lock body just can for one of dead bolt, dead bolt could pass through convex surface, Men Caineng shuts or opens, and the power that gentle breeze blows on door can not make dead bolt pass through convex surface usually, and door just can not opened or shut under the effect of gentle breeze; As long as push away an Xiamen with pin, door just can be opened or be shut, and is very easy to use when the two hand held object of people; Snap close can be for having the steel disc of one section smooth cambered surface of S type, and simple in structure, easy to make, cost is lower.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of Simple door lock, the lock body 1 and the S type snap close 2 that comprise an end opening, spring 3, round end dead bolt 4 are arranged in the lock body 1, and an end of spring 3 is fixed on the lock body 1 interior diapire, and the other end connects the afterbody of round end dead bolt 4, the round end portion of round end dead bolt 4 stretches out from lock body 1 opening part, round end dead bolt 4 can freely stretch under the work of spring 3, and the concave surface 5 of S type snap close 2 matches with the round end portion of round end dead bolt 3, convex surface 6 slynesses.
During use lock body is fixed on the door, S shaped steel sheet is fixed on the doorframe corresponding with the lock body setting height(from bottom), S shaped steel sheet concave, convex face is over against dead bolt.When door is in closed condition, the head of round end dead bolt is positioned at the concave surface of S type snap close, the round end dead bolt is in the nature elongation state, when opening the door, the head of round end dead bolt contacts with the convex surface of snap close through the concave surface of snap close, and the head of round end dead bolt is stressed to contract in lock body under the effect of spring, when the power of opening the door is enough big, the head of round end dead bolt just can slip over the convex surface of snap close, and door is just opened.Otherwise, at closing time as long as when the power of closing the door enough greatly the time, make the head of round end dead bolt slip over the convex surface of snap close, just shut.
