Definitions

  • the utility model relates to the field of weapons technology, namely to the triggers of small arms with a longitudinally-sliding bolt, for example, hunting carbines.
  • the closest analogue of the utility model is the trigger according to patent RU 108583 U1, 09/20/2011 1, description, drawings.
  • This mechanism comprises a housing, a spring-loaded sear, a trigger with a spring, and adjusting screws installed in the housing and vertically oriented, including a trigger for adjusting the trigger force, a screw for adjusting the return of the trigger, and a trigger for adjusting the trigger.
  • the disadvantages of the closest analogue are that the design of the specified trigger has a limitation of the adjustment of the trigger force, including does not provide control of the force of the preliminary trigger.
  • the proposed technical solution consists in expanding the adjustments of the descent, including taking into account the adjustment of the prestress on the trigger. The descent is carried out with the specified parameters of effort (from 150 to 1600 grams).
  • the working range of effort adjustment is divided into 3 intervals, which allowed achieving smooth adjustment in each range and allows you to use the trigger as a “sport” with an effort: 150-300 grams, a “warmint” with an effort: 300-900 grams, or “hunt” with effort: 900-1600 grams.
  • the technical result consists in expanding the adjustment of the descent with the regulation of the efforts of the preliminary descent.
  • the trigger of the small arms comprises a housing, a spring-loaded sear, a trigger with a spring and adjusting screws installed in the housing and vertically oriented, including a trigger for adjusting the trigger force, a screw for adjusting the return of the trigger and a trigger for adjusting the trigger.
  • the trigger of the small arms includes a rocker, a screw for adjusting the overlap of the sear with a rocker, a screw for adjusting the force of the preliminary descent, acting through its spring on the trigger.
  • the trigger adjustment screw acts by means of a spring on the beam, which is located between the sear and the trigger.
  • FIG. 1 is a longitudinal section through the trigger mechanism.
  • FIG. 2 is a side view of the trigger mechanism.
  • FIG. 3 - trigger in cocked state.
  • FIG. 4 - trigger in a deflated state.
  • the trigger device comprises a housing 1, a return spring of a sear 2, a trigger cover 3, a trigger 4, a sear 5, a rocker 6, a pre-release spring 7, a release spring 8, a wheel 9, an adjustment spring trigger 10, screws that secure the cover to the housing 11, the axis of the wheel 12, the axis of the rocker arm 13, the lock washer 14, the axis of the sear 15, the adjustment screw for returning the trigger 16, the adjustment screw for restricting the trigger 17, the adjustment screw for the sear with the rocker 18, the screw for adjusting the pre-launch force 19.
  • the trigger device operates as follows
  • the combat platoon When unlocking the barrel of a small arms (when you turn the bolt to the left and take it back), the combat platoon performs a reverse translational movement. At the moment of movement, when the combat platoon reaches its extreme rear position, the sear 5 is returned under the action of the return spring of the sear 2. In this case, the trigger 4 returns to its original position (before firing) under the action of the pre-release spring 7 and the release spring 8 and is limited by the trigger return screw 16 installed in the trigger housing 1.
  • the trigger mechanism provides the trigger mechanism adjustments following five:
  • Adjustment of the descent force is carried out by turning the adjusting screw of the descent spring 10, which compresses or releases the descent spring 8.
  • the adjustment range is from 150 to 300 grams in the “sport” version; from 300 to 900 grams in the variant “warmint” and from 900 to 1600 grams in the variant “hunt”.
  • the screw is located in the case of the sear 5 and access to it is possible only after removing the bolt from the receiver of the small arms.
  • the trigger 4 After the rocker 6 disengaged from the sear 5, the trigger 4 continues to rotate around its axis 15 under the action of the finger of the arrow until it rests against the trigger adjustment adjustment screw 18. Rotating the trigger restriction adjustment screw 17 decreases or increases the stroke trigger 4 after the descent of the combat platoon. While the axis of the sear 15 is made integrally with the housing of the trigger mechanism 1. 5) In the trigger housing there is an adjustment screw for returning the trigger 16, abutting against which the trigger 4 stops after removing the finger arrow. By turning the trigger return adjusting screw 16, it is possible to adjust the stroke amount of the trigger 4 before firing.
  • the trigger mechanism consists of a minimum number of parts, is easy to assemble and maintain, as it does not require special tools and equipment. All rubbing elements of the trigger mechanism are hardened, which minimizes their wear. Trigger adjustments are made without disassembling the rifle. Thanks to the balanced trigger, the possibility of self-timer is minimized with minimal trigger effort.

Abstract

Le modèle d'utilité concerne un mécanisme de détente pour armes à feu. Le mécanisme de détente comprend un boîtier, une gâchette précontrainte par ressort, un balancier, une détente avec un ressort et des vis de réglage montées dans le boîtier et orientées verticalement. Les vis de réglage comprennent une vis de réglage de l'effort de détente, une vis de réglage de retour de la détente, une vis de réglage de recouvrement de la gâchette avec le balancier, et une vis de réglage de l'effort de détente préalable. La vis de réglage de l'effort de détente préalable agit sur la détente, et la vis de réglage de l'effort de détente agit par le biais d'un ressort sur le balancier qui est disposé entre la gâchette et la détente. On parvient ainis à élargir les réglages de la détente, avec régulation de la détente préliminaire.
