Description
(1) technical field
The utility model is related to a kind of cervical orifice of uterus bolts, belong to hardware class product.
(2) background technology
One fan big and small door, cervical orifice of uterus are generally fixed by bolt and doorframe, and existing latch structure is generally pull type up and down
Latch structure, appearance and size is big, is mounted on door leaf upper and lower ends, and the especially very high door leaf of height uses very inconvenient,
Influence the overall beautiful intensity in door leaf side；And manufacturing cost is higher.
(3) invention content
The technical problem to be solved by the present invention is to provide a kind of a kind of easy to use, at low cost and beautiful cervicals orifice of uterus to insert
Pin.
It is technical solution adopted in the utility model below：
A kind of cervical orifice of uterus bolt, include bolt driving lever, socket, mandrel, axis pin, baffle ring, guide pin, spring, steel ball plug screw,
The part such as steel ball, skewed slot drag hook, cover board and screw is constituted.The bolt driving lever, which is equipped with, manipulates straight trough and guiding safety groove and 7
Word slot guide groove is used for the axial movement of dead bolt driving lever and mandrel；The socket, which corresponds to, is oriented to insurance groove location installation
There is steel ball, steel ball and the gap for being oriented to safety groove are adjusted by the steel ball plug screw on socket, makes bolt driving lever plug rotation spirit
Living and dead bolt driving lever.Bolt driving lever is mounted in socket to be coordinated with socket activity, and bolt driving lever manipulates head and extends
Go out on the outside of socket, the mandrel and spring are mounted within bolt driving lever, and spring one end offsets with mandrel, the other end and bolt
Nose end offsets in driving lever, and the tail portion that upper and lower skewed slot drag hook is mounted on socket is oriented within straight trough；Mandrel is fixed on by guide pin
On 7 word slot guide grooves on bolt driving lever, mandrel offsets with spring
The operation principle of the utility model is：Turn bolt driving lever end face flat recess makes steel ball be detached from and is oriented to safety groove and 7
Word slot guide groove, axle sleeve pop up socket under spring force, and bolt driving lever is pulled to be pulled outwardly by guide pin band moving mandrel,
Mandrel is equipped with axis pin by end, and the skewed slot component that axis pin acts on skewed slot drag hook makes two skewed slot drag hooks receive inwards, realizes door
Fan is vertically connected with bar and activity adjustment fork is pulled to transfer to doorframe pin hole；Bolt driving lever is pressed inwards, bolt driving lever linkage core
Guide pin on axis can be such that two skewed slot drag hooks are flared out by axis pin, realize that door leaf is vertically connected with bar and pulls activity adjustment bolt
Head be inserted into doorframe pin hole, turn bolt driving lever, at the same make steel ball enter guiding locking T words slot and guide pin enter on bolt driving lever
7 word slots circumferential slot, the axial movement of dead bolt driving lever and mandrel.Latching to realize door leaf and doorframe is not beaten
It opens.
The utility model has the advantages that：Since cervical orifice of uterus bolt is mounted on the appropriate height in middle part of door leaf, manipulation is made to get up more
It is convenient；Manipulation is simple, appearance and size is small, beautiful；It is secured that product cost is low, bolt sticks in rear cervical orifice of uterus fan.

(5) specific embodiment
With reference to attached drawing 1- Fig. 7, a kind of cervical orifice of uterus bolt includes bolt driving lever (1), socket (2), mandrel (3), axis pin
(4), baffle ring (5), guide pin (6), spring (7), steel ball plug screw (8), steel ball (9), skewed slot drag hook (10), cover board (11) and screw
(12) etc. portions are constituted.The bolt driving lever (1), which is equipped with, manipulates straight trough (1-1) and guiding safety groove (1-3) and 7 word slots guiding
Slot (1-2) is used for the axial movement of dead bolt driving lever (1) and mandrel (3)；The socket (2) is corresponding to be oriented to safety groove
The position (1-3) is equipped with steel ball (9), adjusts steel ball (9) by the steel ball plug screw (8) on socket (2) and is oriented to safety groove
The gap of (1-3) makes bolt driving lever (1) plug rotation flexibly and dead bolt driving lever (1)；Bolt driving lever (1) is mounted on bolt
Coordinate with socket (2) activity in seat (2), bolt driving lever (1) manipulation head manipulates straight trough (1-1) and extends socket (2) outside
Side, the mandrel (3) and spring (7) are mounted within bolt driving lever (1), and spring (7) one end offsets with mandrel (3), the other end
It offsets with bolt driving lever (1) interior nose end, the tail portion that upper and lower skewed slot drag hook (10) is mounted on socket (2) is oriented to straight trough (2-2)
