Specific embodiment
As shown in Figure 1,2 and 3, a kind of stopping sliding door link-type auxiliary lock, including driver, base 1, carrying axle 3 and lock tongue
11, driver is cylinder 2, it is preferable that cylinder 2 is the internal single-acting Self-resetting cylinder with reset spring, and cylinder 2 is mounted on base
On 1, carrying axle 3 and lock tongue 11 are rotatably mounted on base 1, have actuating arm 12 and swing arm 5 in carrying axle 3, and cylinder 2 is logical
Crossing the mode for pushing actuating arm 12 to swing drives carrying axle 3 to rotate, and carrying axle 3 drives swing arm 5 to swing, and the swinging end of swing arm 5 is logical
It crosses connecting rod 4 to connect with lock tongue 11, swing arm 5 is connect with one end of connecting rod 4 by the first pin shaft 9, the other end and lock tongue 11 of connecting rod 4
It is connected by the second pin shaft 10, realizes that the both ends of connecting rod 4 and the swinging end of swing arm 5 and lock tongue 11 are articulated and connected, 9 He of the first pin shaft
The end of second pin shaft 10 has axis to be fixed with elastic washer, and the wobbling action of swing arm 5 is passed to lock tongue 11, driving lock by connecting rod 4
11 rotary presser of tongue, lock tongue 11 and carrying axle 3 are resetted by resetting-mechanism.
Slide bushing is equipped in the axis hole of connecting rod 4, slide bushing inner surface has self-lubricating abrasion-resistant layer, to prevent and pin shaft
Occurs inordinate wear in rotation process.
Base 1 includes substrate 1-1 and two pieces of installation wallboard 1-2 parallel to each other being vertically arranged on substrate 1-1, swing arm
5, connecting rod 4 and lock tongue 11 are located between installation wallboard 1-2, and the shaft and carrying axle 3 of lock tongue 11 pass through on two installation wallboard 1-2
Axis hole be mounted on base 1, there is in axis hole slide bushing.
The maximum rotation angle of swing arm 5 is close to the mechanism dead point of swing arm 5 and connecting rod 4.The maximum rotation angle of swing arm 5 is by gas
The angle that the driving carrying axle 3 of cylinder 2 rotates determines, installs finite place piece on base 1, carries out to the maximum rotation angle of swing arm 5
Auxiliary stopper.Locating part is limit pin shaft 8, and limit pin shaft is located between installation wallboard 1-2.
Resetting-mechanism directly drives the reset of carrying axle 3, and under the linkage effect of connecting rod 4, lock tongue 11 resets simultaneously；Certainly
It is not excluded for the scheme that resetting-mechanism directly drives the reset of lock tongue 11, under the linkage effect of connecting rod 4, carrying axle 3 resets simultaneously.
Resetting-mechanism is torsional spring resetting-mechanism.In addition to torsional spring resetting-mechanism, other resetting-mechanisms can also be used, are such as used
Compressed spring resetting-mechanism, draw spring reset mechanism.
Torsional spring resetting-mechanism includes torsional spring 6 and connector sleeve 7, and connector sleeve 7 is fixed in carrying axle 3, and 6 sets of torsional spring in carrying axle
On 3, two torsion arms of torsional spring 6 are respectively acting on base 1 and connector sleeve 7, and driving carrying axle 3 resets, in the linkage of connecting rod 4
Under effect, lock tongue 11 resets simultaneously.
Swing arm 5 is sleeved in carrying axle 3 by square hole, is realized and 3 synchronous rotary of carrying axle.
Resetting-mechanism is located remotely from one end of cylinder, and torsional spring 6 is located between connector sleeve 7 and the installation wallboard 1-2 in outside, even
The end that female connector 7 is fixed on carrying axle 3 by being screwed into the screw of the screw hole of carrying axle end, screw are soket head cap screw, connection
Covering 7 inner holes is square hole, matches with the square hole of 3 end of carrying axle, limits the relative rotation between connector sleeve 7 and carrying axle 3,
Two torsion arms of torsional spring 6 are inserted into respectively in the mounting hole of connector sleeve 7 and installation wallboard 1-2.
Course of work description：
After cylinder 2 is inflated, cylinder rod pushes carrying axle 3 to rotate, and the swing arm 5 of carrying axle 3 rotates, and drives 4 He of connecting rod
Lock tongue 11 rotates, at this point, the torsional spring 6 of the end of carrying axle 3 also rotates a certain angle, contacts when swing arm 5 is rotated with limit shaft 8
When, swing arm 5 and lock tongue 11 rotate to maximum angle, and lock tongue 11 compresses door-plate, as shown in Figure 3.
After cylinder 2 is deflated, cylinder rod retraction, under the action of torsional spring 6, swing arm 5 drives connecting rod 4 and lock tongue 11 to be returned to
Initial position, as shown in Figure 1.
The present invention pushes carrying axle by cylinder, so that swing arm rotates by a certain angle with connecting rod, is controlled and is put using spacer pin
Arm maximum rotation angle avoids connecting rod from crossing dead point, and using the effective compression force value output for realizing lock tongue close to dead-centre position, and
Self-resetting is realized using torsional spring, has structure simple, easy for installation, high reliability.
