Description
Technical field
The utility model relates to door lock accessory technical field, concrete relates to a kind of automanual bolt latch.
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.
Existing bolt latch structure is, comprise a pinboard 01 that is installed on the door, the length direction of pinboard 01 is provided with guide groove 02, slidably latch 03 is set in guide groove 02, latch 03 end has crotch 04, some roads is set on the pinboard 01 is used for latch 03 is fixed on hoop 05 in the guide groove 02, and crotch 04 and hoop 05 complement each other to form safe button bit intermittently, when crotch 04 was positioned at button bit, the crotch half-twist can be fixed in the button bit.Accordingly in the corresponding position of doorframe the latch groove is set, move left and right can be inserted or withdraw from the latch groove after latch was deviate from button bit, and mode reaches the function (referring to Fig. 1) of bolting the door and opening 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 make its first half-twist to the dropout position, then at the move left and right latch by instrument in place, slit braking latch pin, 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.
The utility model content
Technical problem to be solved in the utility model is, overcomes the problem that existing bolt latch exists, and provides a kind of automanual security reliability high bolt latch.
In order to address the above problem the technical solution of the utility model is such:
A kind of semi-automatic bolt latch comprises a pinboard that is used to be installed on the door, is arranged on the bolt rod that can slide along its length on the pinboard back side, the hinged connecting rod of described bolt rod root, and the end of the other end of connecting rod and a swing arm is hinged; The other end of swing arm is that fishtail is handled knob, and fishtail is handled knob and exposed front at pinboard, and described swing arm middle part has an axle that is arranged on the pinboard, and length direction is provided with and is used for the swinging chute that swing arm is swung on the pinboard.
Described connecting rod cross section is a spill, is set with a tongue at the back side of pinboard, and the other end of tongue is conflicted in the concave structure of connecting rod, and the connecting rod middle part also is provided with the bearing pin that prevents that tongue from deviating from.
One end of described pinboard has the orifice plate that latch is passed, and described orifice plate is structure as a whole at vertical pinboard and with pinboard.
Axle on the described pinboard is arranged on the pinboard by pedestal, and described pedestal is " several " font pedestal, and pedestal is riveted on the pinboard.
The front of described pinboard has two and refers to groove, and described fishtail is handled knob and referred to swing in the groove scope at two.
The two ends of described pinboard also are provided with and are used for pinboard is installed in installing hole on the door.
Beneficial effect, bolt latch described in the utility model, mechanism's novelty, performance safety by pulling that fishtail is handled knob, can drive the action that bolt rod horizontally slips and whether locks a door, owing to tongue is set at the pinboard back side, tongue conflict connecting rod makes bolt rod only two end position flexible fastenings, can prevent effectively that the robber from adopting special tool to stir latch and opening the door.
