Description

The invention refers to a mechanical control shock-absorbent anti-recoil mechanism, intended for industrial and civil constructions, machine building industry, defense industry, robotics, etc., its purpose being to protect against the impact forces, recoil forces or vibrations that occur in an instantaneous manner or under operation.

There are known shock-absorbent anti-recoil mechanisms that are equipped with springs, telescopic means, hydraulic brakes, magnetic brakes etc. These mechanisms have the disadvantage that they do not provide neither an universal applicability nor possibilities to adjust the effect of the impact forces acting on construction, firearm etc., that occur in an instantaneous or a controlled manner, under the action of the outer impact forces, a recoil or vibrations.

There are also known anti-recoil mechanisms which are able to overtake the recoil energy of the portable firearms. These mechanisms have also the disadvantage that they do not provide an universal applicability, while the component parts of the some assemblies or subassemblies complicate their construction and increase the cost price of the product.

The technical problem that the invention solves consist in the achievement of a mechanical control shock-absorbent anti-recoil universal mechanism which has a simple construction, needs an easy access fabrication technology, ensures an universal use and an important effect of decreasing or even cancellation of the impact forces or of the recoil forces, so that the cancellation of said impact forces or recoil forces which occurs instantaneously or under controlled action be achieved in a continuous manner, according to the protection requirement that is imposed on the operation of the construction, machine, equipment or firearm.

The mechanical control shock-absorbent anti-recoil universal mechanism of the invention solves this technical problem and removes the up-mentioned disadvantages in that it comprises a mobile holder, a joint lever and spring mechanism, and an end holder that comprises a mechanical adjustment mechanism. It comprises also joint spindles, a joint gliding holder, a joint pin, locks, short levers, spring-seat joint pins, absorption springs, a central joint pin, long levers, a cancellation spring-seat pin, cancellation springs, a base holder, a mechanical adjusting mechanism, a spacer, a fitting screw, a spring-seat screw spindle, and holding screws. The above mentioned end holder has a pilot case, in which it is introduced a mechanical adjusting mechanism comprising a triple nut, a central screw, a joint pin, a mounting key and a wear strip and an adjusting key.

The mechanical control shock-absorbent anti-recoil universal mechanism according to the invention has the following advantages:

• • it has an universal applicability;
  • it can be adjusted according to the impact or the recoil force, so that the effects thereof is decreased;
  • it can be used in the field of the civil constructions, industrial constructions, machine construction industry and defense industry.
