Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, below by the technology to the utility model
Scheme is described in detail.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not before making creative work
Obtained all other embodiment is put, the range that the utility model is protected is belonged to.
As illustrated in fig. 1 and 2, latch bolt component 3 is equipped in shell 1, the front end of latch bolt component 3 passes through the inclined tongue hole on panel 2
21, the position in shell 1 positioned at 3 side of latch bolt component is equipped with circular hole 4, is equipped with rotating block 5 in circular hole 4, which can
To be rotated relative to circular hole 4, when rotating block 5 is kept off after rotation on the path that latch bolt component 3 retracts, latch bolt component 3 is just
It can not retract in shell 1, naturally, door also can not just pass through handle for Men Kaiqi from outside.
Further, it as shown in figure 3, the main body of the rotating block 5 is a cylinder 51, is entrenched in circular hole 4, and opposite
Circular hole 4 can rotate, and cylinder 51 extends to form positive stop end 52 and stop bit end 53 to two sides, when positive stop end 52 turns to gear in latch bolt
When on the retraction path of component 3, stop bit end 53 can be against on the side wall of shell 1, avoid positive stop end 52 from continuing to rotate, and rotate
Block 5 can be rotated clockwise or be rotated counterclockwise, and difference is only that, the orientation of positive stop end 52 and the setting of stop bit end 53 is not
Together.Access aperture 54 is additionally provided on cylinder 51, which is mainly used for connecting the knob on door face board, and general knob can be set
It sets on the panel on the inside of door, then without knob on the panel of side located outside the door, therefore also ensures and be only capable of driving on the inside of face
Rotating block 5.
As shown in Figure 1, the latch bolt component 3 includes in the inclined tongue hole 21 latch bolt 31, and after being connected to latch bolt 31
The guide rod 32 at end is additionally provided with guide holder 33 on the shell 1, and guide holder 33 can allow the movement of guide rod 32 more stable, guide rod 32
One end be placed on guide holder 33, spring 35 is cased on the guide rod 32, one end is against in latch bolt 31, and the other end is against guide holder
On 33, the tail end of the guide rod 32 is also connected with limit film 34.When the rotation of positive stop end 52 on rotating block 5 comes and 32 tail of guide rod
When the limit film 34 at end offsets, guide rod 32 just can not be moved further, and latch bolt 31 also can not be just retracted to again in shell 1, led
The spring 35 being arranged on bar 32 after latch bolt 31 can be made to be retracted in shell 1 under normal circumstances and is ejected.
As shown in Figure 1, the side's of being additionally provided with core 6 on shell 1, Fang Xin 6 be with the mutually matched component of square steel on door face board, just
In normal situation, when by rotation handle, Fang Xin 6 can be retracted latch bolt 31 in shell 1 by the cooperation between lock body inner part, together
When mention handle is counter, that is, when being rotated up, square tongue can also be popped up by lock body by the cooperation between lock body inner part, in the skill
In art scheme, the plectrum 7 connected on Fang Xin 6 cooperates with the item 9 of dialling being rotatably connected on shell 1 by the first pin 8, dials
Item 9 is since its lower end is extend between guide holder 33 and limit film 34, when the positive stop end 52 that limit film 34 is rotated on block 5 resists
When, the movement for dialling item 9 is also confined between the two, and related, the movement of plectrum 7 can be limited by dialling item 9, and plectrum 7 passes through limit
System side's core 6, to can not make that square tongue is recovered in shell by rotation side's core 6, therefore, in rotating block 5 to skew bolt shape 31
Other side's tongue forms limit after limit, while also, and under the collective effect of square tongue and latch bolt 31, door is just more difficult to open from outside
It opens.
As shown in Figure 1, being equipped with the second pin 10 on shell 1, torsional spring is connected between the second pin 10 and rotating block 5
11, when rotating block 5 is not turned under limit state, torsional spring 11 can force the state in releasing limit of rotating block 5,
It will not be caused to become limit state due to other external force, can guarantee that door is normally-open usually.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
It encloses, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by the protection of the utility model
Within the scope of.
