Specific embodiment
The embodiments of the present invention are described in detail below in conjunction with attached drawing.
Fig. 1 shows the top view of the utility model embodiment, and Fig. 2 shows the structural schematic diagram of the utility model, Fig. 3
Show the structural schematic diagram that the utility model embodiment mandril stretches out outer cylinder aperture；Fig. 4 shows the utility model embodiment
The structural schematic diagram of mandril retraction outer cylinder.As Figure 1-Figure 4, the utility model provides a kind of theftproof lock of anti-plug card form
Tool, 1 interior containment region of lock tongue of lock are fitting to connection the convex block 701 of 7 one end of outer cylinder, the other end and lockset of outer cylinder 7
Shift fork 8 connect, a mandril 11 is equipped in outer cylinder 7, one end of mandril 11 is right against the aperture of outer cylinder convex block 701, in lock tongue 1
It is equipped with a groove in portion housing region, places latch bolt spring 9 in groove, the other end of mandril 11 is connect with press component, and is pressed
The press section of component is pressed to stretch out outer cylinder 7, mandril 11 stretches out compression latch bolt spring 9 under the driving of press component in aperture to be withstood
Latch bolt spring 9 is discharged in lock tongue 1, or retraction outer cylinder 7；7 wall two sides of outer cylinder are equipped with slanting sliding slot 6, the lock in corresponding 6 region of sliding slot
Limited block 4 is installed on tool pedestal, 11 ontology of mandril extends gag lever post 5 to two sides, and penetrates 7 wall of outer cylinder along outer tube wall
Sliding slot 6 slides, and the left side that the gag lever post 5 of 11 two sides of pushing rod of locking a door encounters limited block 4 stops movement, the end compression of mandril 11
Latch bolt spring 9, which withstands lock tongue 1, is in the lock state lock tongue 1.
The top of the limited block 4 be it is oblique, tilt angle is consistent with the tilt angle of the sliding slot 6.
Reset spring 3 is cased on the outer cylinder 7, lockset pedestal is equipped with guide post 14, and reset spring 3 is located at the lock of outer cylinder 7
On ontology between tongue end and guide post 14.
The ontology that the mandril 11 is located at lock tongue end is equipped with inside boss, is cased with mandril reset spring 10 on boss,
The other end of mandril reset spring 10 is pressed against the convex block 701 of outer cylinder 7.
The press component includes the push rod 13 with ratchet and sliding pawl 12, the connection knot of the push rod 13 with ratchet and sliding pawl 12
Structure is existing structure such as the pressing component of push type ball pen, realizes function such as the pressing function of ball pen.
Press section is the end that the push rod 13 with ratchet exposes outer cylinder 7, and the inner wall of lockset, press component are close in press section
By primary, mandril 11 stretches out the aperture of outer cylinder convex block, and compression latch bolt spring 9 is to withstand lock tongue 1；Press component is pressed once again,
Mandril 11 is retracted in outer cylinder 7；The be pressed driving of component of mandril 11 moves in turn in both states.
Working principle of the utility model is:
1, (as shown in Figure 4) when original state, mandril 11 is retracted in outer cylinder 7, the housing region inside it of lock tongue 1
Or drive outer cylinder that can move left and right together, being can be with free extension；
2, (as shown in Figure 3) when shutdown state, lock tongue 1 is moved right by external force of the doorframe to it, and compression resets
Spring 3, lock tongue 1 move right the convex block 701 for reducing its interior containment region until encountering outer cylinder 7, lock tongue 1 push outer cylinder 7 to
It moves right, after the end for being moved to the push rod 13 with ratchet is pressed onto 2 right side inner wall of lock body, inner wall gives the push rod 13 with ratchet
One opposite thrust pushes mandril 11 to relatively move to the left, so that mandril 11 stretches out 7 aperture of outer cylinder, mandril 11 is driven
The gag lever post 5 of two sides is mobile to upper left side in the sliding slot 6 of outer cylinder 7, and the outer diameter of mandril 11 is 5mm smaller than the internal diameter of outer cylinder 7, so that
Gag lever post 11 just across behind the highest point of limited block 4, is parked in the left side of limited block 4, moves right to limit mandril 11.
Under such state, lock tongue 1 is pushed using plastic tab or card, the latch bolt spring 9 in 1 groove of lock tongue can be withstood on mandril 11,
And the gag lever post 5 on mandril 11 has been limited the control of block 4 to the left at this time, so mandril 11 will not move right.At this point, lock
Gap is formd due to the conflict between latch bolt spring 9 and mandril 11 between tongue 1 and outer cylinder 7, outer cylinder 7 is by less than lock tongue 1
External force, without moving to the right, lock tongue 1 is locked to move right, to reach the anti-of anti-plug plastic tab and card
Steal function；
3, door opening state rotates clockwise shift fork 8 by key or door handle, and shift fork 8 stirs outer cylinder and with ratchet
Push rod 13 drives outer cylinder 7 to move right, after the end for being moved to the push rod 13 with ratchet is pressed onto 2 right side inner wall of lock body, inner wall
13 1 opposite thrusts of push rod with ratchet are given, mandril 11 is pushed to relatively move to the left, mandril 11 drives two sides
Gag lever post 5 is mobile to upper left side in the sliding slot 6 of outer cylinder 7 so that gag lever post 5 moves upwards on the left of limit plate, just across
After crossing the highest point of limited block 4, under the action of mandril reset spring 10, gag lever post 5 is moved right, and is parked in the oblique of limited block 4
On slope, mandril 11 is moved to the right in rear end retraction outer cylinder on the left of it.Outer cylinder 7 also drives lock tongue 1 to move right simultaneously, from
And open door.
The foregoing is merely the preferred embodiments of the utility model, are not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included in the protection scope of the utility model.
