Abstract
The utility model relates to a locking mechanism, particularly the locking mechanism of the rotary T type lock pin of a safety door. A central lock (7) fixed on a frame restricts a central linking hinge (6) which is connected with a T type lock pin mechanism positioned on the edge of a doorframe through a connecting rod (4) and a crank (5), the T type lock pin mechanism is a T type lock pin (1) movably connected with the door frame (2) and a guide sleeve (9), a penetrated spiral groove (10) is arranged on the wall of the guide sleeve, a sliding guide post (11) fixed on a T type lock-pin rod is arranged in the groove, a screw rod (12) is screwed in a pin rod end and is locked by nuts, and a hinge (14) and a steel ball (15) are movably connected with a push post (17) and are positioned by pins (18) so as to realize the rigid rotation and connection. When the guide post (11) slides to an upper dead point along the spiral groove (10), the T type lock pin is rotated 90DEG and is firmly clamped on an edge frame (8), and if the central lock (7) is not opened, and the central linking hinge is not moved, the safety door is difficult to open so that the reliability and the anti-prizing performance of the safety door are enhanced.
Description
A kind of retaining mechanism, especially rotating T type lock pin retaining mechanism relates to the safety door latch technical field.
Safety door is widely used as the pick-proof and anti-theft measure.The retaining mechanism of safety door is also varied.In the known technology, major part is the form of smoothly selling directly to households, therefore, the quality of safety door is influenced to some extent, and the pick-proof performance decreases, and also uses to resident family and brings many inconvenience.
The purpose of this utility model is to provide a kind of form of structure more reliable, the safety door locking mechanism that the pick-proof performance is stronger.
For achieving the above object, the utility model proposes following technical scheme:
By T type lock pin, doorframe, T type latch gear, connecting rod, crank, interlock hinge, center lock, form the overall structure that safety door rotates T type lock pin retaining mechanism.
Be fixed on center lock (7) the restriction center interlock hinge (6) on the framework, connect the T type latch gear (3) that is in the doorframe edge through connecting rod (4), crank (5).
T type latch gear is made up of T type lock pin (1), pin rod, fairlead (9) helicla flute (10) lead (11), screw rod (12), nut (13), movable joint (14), steel ball (15), fore-set (16).
Above-mentioned T type latch gear, be that T type lock pin (1) is movably connected in doorframe (2) and the fairlead (9), on the guiding jacket wall penetrating helicla flute (10) is arranged, have in the groove slip and be fixed on lead (11) on the T type lock pin bar, the pin rod end screws in screw rod (12), with nut (13) locking, flexibly connect fore-set (16) by movable joint (14) and steel ball (15).Establish 1 steel ball between screw rod and the fore-set, establish 3-18 steel ball between screw rod and the movable joint, with pin (17) location.
Center interlock hinge (16) is on 1 direction of doorframe (2) by the T type latch gear that connecting rod (4) is connected, or on 2 directions, or on 3 directions, or up and down on 4 directions.
In the T type latch gear on each direction, be 1 T type lock pin or 2 T type lock pins arranged side by side, or 3 T type lock pins arranged side by side.
During T type lock pin movement, lead (11) slides into top dead-centre along helicla flute, and T type lock pin rotates 90 °.
Owing to adopt above technical scheme, make obvious improvement and the characteristics of having the utlity model has: after T type lock pin rotates 90 °, firmly be stuck on the frame,, do not move center interlock hinge if do not open center lock, T type lock pin is difficult to reset, want to destroy safety door, or want to pry open safety door, it is time-consuming to require great effort, increase difficulty, really improved the reliability and the pick-proof performance of safety door.
Accompanying drawing of the present utility model and drawing explanation:
Fig. 1 is that safety door rotates T type lock pin retaining mechanism overall structure figure
Fig. 2 is the T type latch gear elevation that amplifies
Fig. 3 is the schematic diagram that is connected to after T type lock pin rotates 90 ° on the frame
Among the figure: 1T type lock pin, 2 doorframes, 3 T type latch gears, 4 connecting rods, 5 cranks, 6 centers interlock hinge, 7 center locks, 8 frames, 9 fairleads, 10 helicla flutes, 11 leads, 12 screw rods, 13 nuts, 14 movable joints, 15 steel balls, 16 fore-sets, 17 pins.
The utility model is described in further detail below in conjunction with drawings and Examples:
As Fig. 1, center lock 7 is fixed on the framework and restriction center interlock hinge 6, handgrip drivening rod 4 and crank 5, transmission T type latch gear 3.T type latch gear is provided in a side of on 1 direction of doorframe, or on 2 directions, or on 3 directions, or up and down on 4 directions.On upper and lower, right 3 directions that present embodiment is provided in a side of.T type latch gear on each direction be unit independently, or 2 arranged side by side, or 3 are arranged side by side.Present embodiment is 2 units of the right assembling, each 3 T type latch gear arranged side by side up and down.
As Fig. 2, above-mentioned T type latch gear 3 is made up of T connector, fairlead, helicla flute, lead, pin rod, screw rod, nut, movable joint, fore-set, steel ball.T type lock pin 1 and pin rod are slidingly connected among doorframe 2 and the fairlead 9, have helicla flute 10 on the guiding jacket wall, and the lead 11 that is fixed on the lock pin bar moves in groove, during motion, T type lock pin begins to rotate, and lead is during to top dead-centre, T type lock pin rotates 90 °, firmly is held on the frame 8.The pin rod end screws in screw rod 12, with nut 13 lockings.Flexibly connect with movable joint 14 and steel ball 15 between screw rod mouth and the fore-set 16, and locate with pin 17.Between screw rod and the band alive 3-18 steel ball arranged, 1 steel ball is arranged between the fore-set of screw rod.
