Fig. 3 is the structural representation of the utility model locking bolt and the common blocking of hook-shape latch.
The drawing reference numeral explanation: 1 locking bolt driving mechanism, the 2-locking bolt is found a place to live in, 3-lock bolt push rod, 4-spring, 5-pivot pin, 6-hook-shape latch, 7-locking bolt chamber, 8-locking bolt, 9-locking bolt core muscle, 10-location-plate, 11-lock housing.
The specific embodiment
Referring to Fig. 1, locking bolt driving mechanism 1 of the present utility model is arranged in the lock housing 11, locking bolt driving mechanism 1 is the locking bolt driving mechanism 1 by handle especially key actuated, and locking bolt driving mechanism 1 can adopt existing structure or through the improved various driving mechanisms that are adapted to drive locking bolt.The locking bolt of locking bolt driving mechanism 1 is found a place to live in and 2 is connected with locking bolt 8.Locking bolt 8 is provided with locking bolt chamber 7, but is provided with the hook-shape latch 6 of radial deflection to locking bolt chamber 7 in the locking bolt chamber 7, and the tail end of hook-shape latch 6 is by pivot pin 5 hinged securement.Fixedly the pivot pin 5 of hook-shape latch 6 is to be positioned at lock housing 11 for good, and pivot pin 5 can be fixed in locking bolt 8 the inners, also can be fixed in locking bolt and find a place to live on the position of 2 close locking bolt 8.The tail end of shape lock bolt 6 is good so that the back-moving spring 4 that hook-shape latch 6 can be regained locking bolt chamber 7 to be set.One end of spring 4 is fixedlyed connected with the tail end of hook-shape latch 6, and the other end of spring 4 is fixed on the lock housing 11.The tail end of hook-shape latch 6 is a hook-type.Locking bolt is found a place to live in and 2 is provided with and the corresponding lock bolt push rod 3 in hook-shape latch 6 positions, is provided with corresponding location-plate 10 with hook-shape latch 6 positions in the lock housing 11, the lock housing 11 double as location-plates 10 of also available locking bolt 8 sides.When lock bolt push rod 3 advances, can cooperate the hook-type tail end medial and lateral while application of force that constitutes, make hook-shape latch 6 deflect to the locking location with location-plate 10 to hook-shape latch 6.The locking bolt core muscle 9 of enhance mechanical strength also can be set in the locking bolt chamber 7, and locking bolt core muscle 9 is fixed with one with locking bolt chamber 7.Locking bolt 8 of the present utility model can adopt one to multiple group.
A hook-type only is set on the locking bolt 8 of the present utility model locked a door 6 o'clock, hook-shape latch 6 is divided into two sides in the locking bolt chamber 7 with locking bolt core muscle 9.Locking bolt chamber 7 can be that the locking bolt 8 of the right hatch frame of mouthful word constitutes by cross section specifically, and locking bolt core muscle 9 is fixed in the closed side of the right opening font of mouthful word locking bolt 8, hook-type 6 open side that are arranged at the right opening shape of mouthful word locking bolt 8 of locking a door.Locking bolt chamber 7 can be locking bolt 8 formations of "=" number structure by cross section also, and locking bolt core muscle 9 is fixed in a side of "=" number shape locking bolt 8, and hook-shape latch 6 is arranged at the opposite side of "=" number shape locking bolt 8.Locking bolt 8 if adopt a material base to be processed into a single piece, can have intensity preferably with locking bolt core muscle 9.
A pair of hook-type is set on the locking bolt 8 of the present utility model locked a door 6 o'clock, it is divided into two sides in the locking bolt chamber 7, and locking bolt core muscle 9 is arranged between a pair of hook-shape latch 6.
Referring to Fig. 2, during locking, key drives locking bolt driving mechanism 1, drives locking bolt and finds a place to live in and push away before 2, and locking bolt 8 is released lock housings 11.Locking bolt 8 can be advanced into the axial lock location through one-level, secondary or multistage driving.
One of closedown mode of the present utility model be one-level drive finish simultaneously axially, radially common locking, the locking process is: locking bolt 8 drives when being advanced into the axial lock location through one-level, lock bolt push rod 3 is found a place to live in locking bolt and is pushed into the locking bit of hook-shape latch 6 before 2.In the process that pushes away before lock bolt push rod 3, when the hook-type tail end medial and lateral for the treatment of hook-shape latch 6 were subjected to the position-limiting action of lock bolt push rod 3 and location-plate 10 simultaneously, hook-shape latch 6 began around pivot pin 5 inclined to one side, and hook-shape latch 6 front end deflections go out locking bolt chamber 7 to the locking radial position.Referring to Fig. 3,
Two of closedown mode of the present utility model is that multistage driving is finished axially successively, radially common locking, the locking process is: locking bolt 8 has carried out earlier one-level, secondary or multistage driving again and has advanced, when locking bolt 8 arrives the axial lock location through drive advancing again or afterwards, hook-shape latch 6 deflects to the locking radial position under the effect of lock bolt push rod 3 and location-plate 10.During multistage driving locking, advance real coral by in the process of locking at locking bolt 8, hook-shape latch 6 is pind down by spring 4 and takes in fully in locking bolt chamber 7, and along with locking bolt 8 advances synchronously.When realizing radially locking, the active force of lock bolt push rod 3 and 10 pairs of hook-shape latch 6 of location-plate has overcome the restraining function power of spring 4, makes hook-shape latch 6 realize the locking radial positions.Referring to Fig. 3.
When unblanking, key drives locking bolt driving mechanism 1 reverse drive locking bolt 2 rollbacks of finding a place to live in, lock bolt push rod 3 becomes big gradually with the spacing of location-plate 10, when the active force of lock bolt push rod 3 and 10 pairs of hook-shape latch 6 of location-plate reduces gradually, hook-shape latch 6 is reset to gradually and takes in locking bolt chamber 7 under the effect of spring 4 restoring forces.When locking bolt 8 also rollback is to lock housing 11, finishes and unblank.
