The technique effect of design of the present utility model, concrete structure and generation is carried out below with reference to embodiment and accompanying drawing
Clearly and completely describe, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of embodiment of the present utility model, rather than whole embodiments, based on embodiment of the present utility model, the skill of this area
The other embodiment that art personnel are obtained on the premise of not paying creative work, belongs to the model of the utility model protection
Enclose.In addition, all connection/annexations being previously mentioned in text, not singly refer to component and directly connect, and refer to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, to constitute more excellent draw bail.Each technology in the invention is special
Levy, can be with combination of interactions on the premise of not conflicting conflict.
A kind of 1~Fig. 2 of reference picture, lockset gear box includes and includes travelling gear, in housing 1, the housing 1
One rack and the second rack and front end face, first rack and the second rack are located on front end face, first rack and the
Two racks are ratcheting with travelling gear, and the first rack and the second rack are respectively provided at the front and rear sides of travelling gear, in addition to
There is drive device 2, the drive device 2 includes crank connecting link group, and the crank connecting link group includes drive block 21 and connecting rod
22, the drive block 21 is hinged with housing 1, the two ends of connecting rod 22 are hinged respectively at drive block 21, the first rack；The housing 1
Baffle plate 11 is provided with, the baffle plate 11 is located at the outside of the crank connecting link group.
Described drive block is provided with a hole slot, and hole slot can be that square hole or polygonal hole can even is that and do not advise
Supporting handle, when use, need to only be inserted into hole slot, firmly be turned out drive block, drive block by hole slot then
When rotating, the first rack is driven to stretch out by connecting rod, because the first rack is ratcheting by travelling gear with the second rack,
Described the second rack is also common protruding, now when the first rack stretches out, and need to only be installed at the two ends of rack
Dead bolt or lock point, you can realize locking for door and window；And when firmly drive block is inwardly rotated, the first rack and the second tooth
Bar is then to contract, so as to realize the open mode of door and window.And work as rack in the case of fully extended, drive block or connecting rod
Outer face have baffle plate abutting, when having external force to want to promote rack retraction, external force can cause crank connecting link group continues outside
Rotate, and due to being provided with baffle plate in housing, baffle plate has propped up the movement tendency of crank connecting link group, so that rack can not be
Retraction is realized under the driving of external force, can only inwardly be rotated by rotating drive block, lockup state can be released, improved well
Security performance.
It is further used as preferred embodiment, first rack includes teeth section, linkage section and locking section, described
Teeth section is connected with travelling gear, and the rear side of the linkage section is provided with connecting seat, and the connecting rod 22 is hinged with connecting seat.The lock
The rear side that only section and the second rack are coplanar, the teeth section is located at the travelling gear, the linkage section and teeth section, the company
It is arc transition to connect between section and locking section.In order that the gear box structure for obtaining lockset is compacter, the body of gear box is reduced
Product, by causing the first rack to be in meander line structure so that the first rack and the second rack are when locking, and stress point is located at same
In one plane, the security of lockset is higher.
It is further used as preferred embodiment, also includes and torsion spring pin 12 is provided with torsion spring 3, the housing 1, it is described
Torsion spring 3 includes two connecting pins, and described two connecting pins are connected respectively at torsion spring pin 13, drive block 22.When drive block exists
When rotation, due to receiving the active force of torsion spring, it can to provide preferably damping sense when drive block is rotated,
And by setting the installation site of torsion spring, can make it that spring force of the drive block on two extreme positions is minimum, so that
The handling for obtaining lockset is more preferable.
It is further used as preferred embodiment, the front end of the housing 1 is provided with outer panels 13, the outer panels 13 and the
Flexible member is provided between the rack of one rack/second.Using outer panels, protection gear box internal structure can be not only played, outside
Panel causes gear box more attractive generous.Certainly, the length of described outer panels is not less than the completion extension elongation of two racks,
So as to play a part of protection with blocking.Described flexible member can be spring leaf either plastic parts, be mounted with elastic member
After part, it is ensured that rack can press close to the front end face of housing all the time in slip, rack is placed in slip because front and rear race
Partially so as to cause to send abnormal sound or influence the smooth of slip.
It is further used as preferred embodiment, it is solid by tubular rivet between the outer panels 13 and the front end face of housing 1
Fixed connection.When installation, outside is fixedly connected by realization with housing by tubular rivet, then recycles screw to pass through
Tubular rivet, is fixed installation by whole lockset and door and window, improves installation reliability and convenience.
It is further used as preferred embodiment, the housing 1 includes in drain pan and upper lid, the drain pan and includes peace
Seat 14 is filled, the mounting seat 14 is fixedly connected with housing 1, the mounting seat 14 is provided with screw.Because housing is all by plate
Material machine-shaping, its thickness is little, and traditional drain pan with upper lid is fixedly connected by screw, and the thickness of drain pan and upper lid
Limited, so that the connection reliability of screw is not very big, and the utility model then passes through four corner locations in drain pan
The mounting seat of a U-shaped is welded at place, and then screw is screwed in mounting seat simultaneously when installing, due to the threaded connection of screw
Part is more, therefore the connection of drain pan and upper lid is more reliable, more firm.Certainly, more may be used in order that obtaining drive block in rotation
Lean on, the inner surface of described upper lid is provided with guide pad, and the upper surface of drive block is provided with arc guide groove, and guide pad is being oriented to
Be slidably connected in groove, due to upper lid be relatively fixed it is motionless, therefore drive block on the move can guide groove guiding to entering
Row movement, the reliability of action is higher.
Better embodiment of the present utility model is illustrated above, but the invention be not limited to it is described
Embodiment, those skilled in the art can also make a variety of equivalent changes on the premise of without prejudice to the utility model spirit
Type or replacement, these equivalent modifications or replacement are all contained in the application claim limited range.
