Description

pressing the slider 3 to the stop 5. The cavity of the slider 3 is bounded on one side by plate 6, ball 7 and cover 8, and on the other by the end of slider 3 which is hinged in the cavity 3 of rod 9 of stopper 10. Rod 9 is rigidly connected to stopper 10. Between rod 9 and the plate 6 in the slider 3 of the slide 3 is spring I. The movement of the rod 9 under the action of the spring 11 is limited by the collar 12. The stopper 10 is equipped with a ball 13 and is held in the bushing 14 pressed into the frame 2. The fixed element 15 is provided with an opening 16. On the ball 7 slider 3 is affected externally by R.

The latch works as follows. Under the action of force P on the ball 7, the slider 3 moves in the cavity of the housing 1 by moving the rod 9 of the stopper 10 by means of the spring 11 in the direction of the fixed element 15, which is mixed in a plane perpendicular to the direction of the movement of the stopper 10. The stopper 10 the surface of the fixed element 15 stops and then the ball 13 slides along the moving surface of the fixed element 15. When stopper 10 stops, slider 3 continues to move in the direction of the force P, compressing the springs 11 and 4 at the same time. The Alzun 3 pr) reins 11 and 4 are in the cocked state. As soon as the stopper 10 when the ball 13 slides into the hole 16 of the moving locking element 15, the spring 11 immediately triggers, inserting the stopper 10 into the hole 16 and thereby stopping the movement of the locking element 15. This is how the locking operation proceeds. Further, when the force P is removed, the spring 4 simultaneously opens, moving the slider 3 in the opposite direction. The slider 3, acting on the flange 12 of the rod 9, pulls the stopper 10 behind itself and leads it out of the hole 16 of the fixed element 15. The element is unlocked and has received the possibility of further movement. This completes the operation of the lock. The described cycle can be repeated at the desired process frequency.

Palichi in the case of the spring-loaded slider and the placement in the cavity of the spring, acting on the stopper blade, provide the following advantages to the clamp as compared to the existing ones: the ability to immediately unlock after removing the force P and applying the proposed design of the lock B to the locking mode and in the automatic mode performing locking and unlocking operations.

Ф о Р м} л and inventions

A clamp comprising a housing and moving a spring-loaded pin with a stopper, characterized in that, in order to ensure automatic unlocking of the stopper and speed, it is equipped with a slide mounted in the corus and iodine in the direction from the stopper in the inner cavity of the rod.
