Abstract
The utility model discloses a latch bolt structure. The latch bolt structure comprises a pinboard installed on a door, and a bolt rod which is arranged on the back of the pinboard and capable of sliding along the length direction. A connecting rod is hinged with the back of the bolt rod. A swing arm is positioned in the middle of the pinboard. The top of the swing arm is arranged above the pinboard. The middle part of the swing arm is connected with the pinboard through a rotating shaft. The bottom of the swing arm is hinged with the top of the connecting rod. A swing groove used for the swinging of the swing arm is arranged along the length direction of the pinboard. Compared with the prior art, the latch bolt structure is capable of driving the bolt rod to slide horizontally and finish the action of locking and unlocking by pulling the swing arm. The swing arm arranged on the pinboard collides with the connecting rod so that the bolt rod is only flexibly connected with two end portions, and therefore the danger that thieves toggle the bolt to open the door by using special tools is avoided. The latch bolt structure is novel in structure and secure in performance.
Description
Technical field
The utility model relates to a kind of box bolt accessory, particularly a kind of bolt latch structure.
Background technology
People are provided with the bolt latch in daily life for antitheft in the inboard of door, like this people in entering the room after, manually promoting latch can lock door, to guarantee indoor security.
As depicted in figs. 1 and 2, in the existing bolt latch structure, it comprises a pinboard 10 that is installed on the door, length direction at pinboard 10 is provided with guide groove 20, at guide groove 20 interior settings movable end 30 slidably, the bottom of movable end is connected with latch 40, is provided with spacing hole 21 in guide groove 20, movable end 30 is fixed in the spacing hole 21, to be used for Fixed latches 40 with respect to the position of pinboard 10.Accordingly in the corresponding position of doorframe the latch groove is set, after latch 40 was deviate from spacing hole 21, move left and right can be inserted or withdraw from the latch groove, and mode reaches the function that bolt opens the door according to this.
But above-mentioned bolt latch, structure is too simple, safety is not high, because latch is free to slide in the guide groove again, so the robber can move it the dropout position by instrument in place, slit braking latch pin, and then the move left and right latch, latch is withdrawed from the latch groove, and door can have been opened; So there is potential safety hazard in the bolt latch of similar structures.
Therefore, need especially a kind of bolt latch structure, to solve the above-mentioned existing problem that exists.
The utility model content
The purpose of this utility model is to provide a kind of bolt latch structure, solves the defective of above-mentioned prior art, and safety and reliability is high, and is simple in structure, very practical.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of bolt latch structure, comprise a pinboard that is used for being installed on the door, the bolt rod that is arranged on the pinboard back side and can slides along its length, it is characterized in that, the hinged connecting rod in described bolt rod rear portion, the centre position of described pinboard is provided with a swing arm, the top of described swing arm is positioned at the top of described pinboard, the middle part of described swing arm is connected on the described pinboard by an axis of rotation, the bottom of described swing arm and the top of described connecting rod are hinged, are provided with the swinging chute that swings for swing arm at the length direction of described pinboard.
In an embodiment of the present utility model, the two ends of described pinboard bottom are respectively arranged with the orifice plate that bolt rod is passed, and described orifice plate and described pinboard are orthogonal and be wholely set with described pinboard.
In an embodiment of the present utility model, described axis of rotation is arranged on the described pinboard by pedestal, and described pedestal is " several " font pedestal, and described pedestal is riveted on the described pinboard.
In an embodiment of the present utility model, the top of described swing arm is to handle knob.
In an embodiment of the present utility model, be provided with the finger groove in the both sides of described swinging chute.
In an embodiment of the present utility model, have in described bolt rod outer cover to prevent the stainless steel tube that gets rusty.
Bolt latch structure of the present utility model, compared with prior art, by pulling of swing arm, can drive the action that bolt rod horizontally slips and locks a door and open the door, owing at pinboard swing arm being set, swing arm conflict connecting rod, so that bolt rod can prevent effectively that only two end position flexible fastenings the robber from adopting special tool to stir latch and opening the door novel structure, performance safety is realized the purpose of this utility model.
Characteristics of the present utility model can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained to be well understood to.
