Specific embodiment
The term or vocabulary used in this specification and claims book should not be limited to containing on common or dictionary
Justice explains that the structure shown in the embodiment and figure described in this specification is an optimal implementation of the present utility model
Example, it is impossible to all technological thoughts of the present utility model are represented, it is therefore to be understood that can have energy in application of the present utility model
Enough instead of these various equivalent structures and variation.
Latch bolt with rotary latch of the present utility model is a structure of door lock assembly installed on a door.
On this latch bolt with rotary latch of the present utility model, carried out in detail with reference to the accompanying drawing for representing an embodiment
Describe in detail bright.
It is described as follows referring to figs. 1 to Fig. 5.
Door lock assembly includes door lock assembly 1 and latch bolt 2 this two large divisions with rotary latch, wherein, the door lock
Component 1 has handle, and the latch bolt 2 is installed on the side of the door lock assembly 1, can be operated by handle.
In general, door lock assembly 1 has any one handle in rotary, extending type or driving, by described
Hand, is arranged on rotary latch in latch bolt 2 and retreats, and by elastic component, before rotary latch and then resets.
In this latch bolt 2 with rotary latch, rotary latch is rotated (SPIN) in advance or retrogressing, bag
Include following several major：Housing 10, is installed as being inserted into the mounting groove being formed on door；Rotary latch 20, it is prominent
The one side of the housing 10, a portion insertion case inside are installed on, and are rotated in advance or retrogressing；It is sliding
Body 30, is arranged at the inner side of the housing 10, and breech lock 20 can be driven to retreat；Breech lock elastic component 40, is arranged at the housing
In 10, enable to advance for flexibly supporting breech lock 20 and gliding mass 30；With rotary operating member 50, it is connected with handle, in rotation
When drive the gliding mass 30 to retreat.
The housing 10 is inserted in the mounting groove being formed on door, is used to house gliding mass 30, elasticity with inner space
Part 40 and rotary operating member 50, are formed with for breech lock 20 through the breech lock guide hole 12 installed in one side (above) 11, described
Breech lock has more than one breech lock spigot surface 13 with guide hole 12.The spigot surface 13 be formed on the axis of guide 22 of breech lock 20
Rotary spigot surface 22a contact so that breech lock 20 can rotate (SPIN) when moving forward and backward.
This housing 10 is for ease of installation breech lock 20 and is easy to internally space mounting gliding mass 30, elastic component 40
And rotary operating member 50, typically it is made up of housing body 10a and lid 10b.
Referring to Fig. 4 to Fig. 6, the rotary latch 20 is installed in the way of through breech lock guide hole 12, and is arranged at
Breech lock elastic component 40 in housing 10 is flexibly supported, and is moved forward and backward when rotated, including：Breech lock head 21, has
To the inclined-plane 21a protruding outside of housing 10；The axis of guide 22, through breech lock guide hole 12, rotatably leads with more than one
To face 22a；Left/right rotation uses rotation axle portion 23 instead, and between the breech lock head 21 and the axis of guide 22, its diameter is less than guiding
The diameter of axle 22, into breech lock with guide hole 12, so that breech lock 20 can be in the state of without external world's interference with axis of guide center C
On the basis of rotate；Positioned at the snap ring 24 of the inner side of gliding mass 30；With fixing bolt 25, for the snap ring 24 to be fixed on into the axis of guide
22。
Preferably, the rotary spigot surface 22a being formed on the axis of guide 22 is formed as spirality so that rotary door bolt
Lock 20 is rotated on the basis of the C of axis of guide center, be formed at inclined-plane 21a on the breech lock head 21 also with rotary spigot surface
It is spirality that 22a is identically formed.
The breech lock 20 is installed to be that breech lock head 21 is protruding outside to housing 10, is directed to axle 22 through housing 10
Guide hole 12 and the Kong Zhonghou being formed on gliding mass 30, snap ring 24 is installed using fixing bolt 25.
This breech lock 20 is contacted with the pushing surface of the slot being arranged on doorframe and is individually retreated that (breech lock is to housing by promotion
Side shifting), in addition in gliding mass 30 when being retreated in the presence of handle, the breech lock 20 can be moved together with the gliding mass.Retreat
Breech lock 20 and gliding mass 30 it is preceding again in the presence of breech lock is with elastic component 40 so that reset.
That is, include for the whirligig that the rotation of breech lock 20 is driven when moving forward and backward in breech lock 20：It is more than one
Breech lock spigot surface 13, is formed in the breech lock guide hole 12；More than one spiral rotary spigot surface 22a, shape
Cheng Yu with the axis of guide 22 of guide hole 12, and is contacted through the breech lock with breech lock spigot surface 13.
Referring to Fig. 7, it is allowed to retreat in promotion breech lock head 21, and the left/right rotation uses rotation axle portion 23 instead and is located at breech lock
With in guide hole 12, and when driving breech lock head 21 to rotate, breech lock as constructed as above 20 can be revolved centered on the C of axis of guide center
Turn such that it is able to change the inclined-plane 21a of breech lock head 21 to the left and right as shown in (a) of Fig. 7.
The gliding mass 30 is installed on the inner side of housing 10, and is installed as being retreated by handle, retreat when and breech lock
20 move together such that it is able to drive breech lock 20 to be retreated under handle effect.The gliding mass 30 is formed as "U" shaped structure, institute
The top 31 and bottom 32 for stating gliding mass 30 are formed with nipple hole 34, and the nipple hole 34 supplies the card being arranged on rotary operating member 50
Only inserted with projection 52, the front face 33 of the gliding mass 30 is formed with the perforation run through for the rotation axle portion 23 of breech lock 20.
When rotary operating member 50 rotates, this gliding mass 30 is retreated by locking projection 52, now breech lock 20
Move together.But when breech lock 20 is contacted and retreated with the pushing surface of the slot being arranged on doorframe, gliding mass 30 will not be moved.
The gliding mass 30 retreated together with the breech lock 20 in the case where (disappearance) active force (load) is lost, by breech lock
With before elastic component 40 and then resetting.
The breech lock elastic component 40 is located at the rear of rotary latch 20 and is installed in the inner side of gliding mass 30, and uses
In resilient support rotary latch 20, when rotary latch 20 and gliding mass 30 are retreated, the breech lock drives institute with elastic component 40
State before rotary latch 20 and gliding mass 30 and then reset.
The rotary operating member 50 is the structure that gliding mass 30 can be driven to retreat movement when being rotated by handle, including：
Connecting hole 51, for the rotary operating member 50 and handle 1a to be connected, so that in operating handle 1a, behaviour is rotated
Workpiece 50 rotates；With more than one locking projection 52, it is inserted in the nipple hole 34 being formed on gliding mass 30, when described
When rotary operating member 50 rotates, the locking projection 52 can drive breech lock elastic component 40 to retreat.That is, described locking uses prominent
It is multiple to play 52, and is inserted in and is respectively formed in the nipple hole 34 on the top 31 of gliding mass 30 and bottom 32.
This rotary operating member 50 carries out forward or reverse by handle, and locking when rotated drives gliding mass 30 with projection 52
Retreat (referring to Fig. 5).
