Description

Trigger anti-aircraft device

The invention relates to a trigger device, in particular to a crossbow trigger anti-aircraft device.

Press, the crossbow is mainly composed of a bow body and a bow arm. There is a handle at the rear end of the bow, and a firing device is provided on the front side of the handle. The firing device includes: a trigger seat, a safety piece, a wire catcher and A trigger, the firing device is equipped with a sight, the bow arm is curved, installed near the front end of the bow body, crosses with the bow body to form a cross shape, and a bowstring is combined between the two ends of the bow arm; when in use, the bowstring is backward Pull to make the bowstring tense and fasten with the firing device, then put an arrow body on the bow body and stick to the stretched bowstring, aim at the target through the scope, pull the trigger of the firing device, and make the bowstring Breaking away from the firing device, the arrow body is pushed out by the bowstring.

However, although the firing device of the existing crossbow can provide the effect of firing the arrow body, the firing device can be placed in a closed safety state that cannot be pressed by pushing the safety part, so as to avoid accidental shooting of the arrow due to accidentally touching the trigger. However, in the existing crossbow, when the bow string is stretched and hooked on the thread catcher, if the user accidentally touches the trigger when the bow and arrow are not placed in the firing device, the bow string will be connected to the trigger. The thread hook is separated and ejected forward, resulting in an empty shot, resulting in that the energy of the bow cannot be converted into the speed of the arrow body, and can only be borne by the crossbow itself, so that the arms and strings of the crossbow may not be able to withstand the energy. Not only will the service life of the crossbow be shortened, but the suddenly broken bow arm and bow string will easily cause safety hazards to the user or the surrounding personnel.

Therefore, there is a conventional trigger anti-aircraft device shown in the tenth figure to the fourteenth figure (such as the No. I656318 invention patent of China's announcement), which is installed in a percussion device, including: a shell seat 91, which It has a first end 911, a second end 912 and a bottom end 913 between the first end 911 and the second end 912. An assembly chamber 914 is formed in the shell seat 91, and the first end 911 is concave A sectional groove 915 is provided and communicates with the assembly chamber 914. In addition, two long groove holes 916 are arranged horizontally on the side of the shell base 91 to correspond to each other and communicate with the assembly chamber 914. The bottom end 913 is provided with an opening 9131 to communicate with the assembly chamber 914; Group 92, it is installed in the assembly chamber 914, and this percussion group 92 comprises a catch 921, a percussion part 922, a safety slider 923, a connecting piece 924, an elastic member 925 and a positioning block 926, the The trigger piece 921 is pivotally assembled in the assembly chamber 914 and protrudes from the opening 9131 with one end. The triggering piece 922 is pivotally arranged in the assembly chamber 914 and is close to the cutaway groove 915. After pivoting in the assembly chamber 914, the triggering piece 922 and One end of the catch piece 921 is stuck against each other. When the firing piece 922 is not pivoted, it is arranged at a distance from the catch piece 921. The safety slider 923 is arranged in the assembly chamber 914 and corresponds to each long groove 916. The safety slider 923 Corresponding to the two long groove holes 916, two sliding rods 9231 protrude, and each sliding rod 9231 passes through the corresponding long groove hole 916 respectively; The movement pushes against the displacement of the connecting piece 924. In addition, one end of the connecting piece 924 corresponding to the second end 912 is provided with a perforation 9241, and in the assembly chamber 914, a shaft 9141 is provided adjacent to the connecting piece 924 with a perforation 9241. One end, the two ends of the elastic member 925 are respectively sleeved on the shaft rod 9141 and the perforation 9241; and the positioning block 926 is pivotally arranged in the assembly chamber 914 and is located on one side of the slit 915, and the connecting piece 924 faces the positioning block 926 After the position is moved, the pivot of the positioning block 926 is restricted, and when the positioning block 926 is released from the restriction of the connecting piece 924, it pivots and protrudes from the cutaway groove 915; the safety slider 923 moves toward the first end 911 and pushes against the connection The displacement of the piece 924, the displacement of the connecting piece 924 pulls the elastic storage force of the elastic member 925 at the same time, and the connecting piece 924 also limits the pivoting of the positioning block 926 to form a firing mode; wherein, when the firing device is in the firing mode To replace the crossbow, it is necessary to switch the safety slider 923 again to move toward the second end 912, and the connecting piece 924 is pulled by the elastic force of the elastic member 925 to move toward the second end after the restriction of the safety slider 923 is released. Sliding in the direction of the end 912, the connecting piece 924 is released to restrict the pivoting of the positioning block 926, and the positioning block 926 pivots in the direction of the cut-away groove 915 to prevent injury caused by the ejection of the empty-string firing.

However, in this conventional trigger anti-aircraft device, although its positioning block 926 can be pivoted through the elastic force of the return spring, a part of the positioning block 926 protrudes from the cutaway groove 915, so as to limit and stop the bowstring 93, avoiding The bowstring 93 bounces to the hand of the user, or the bowstring 93 bounces against the bow and arrow during the process of pulling out the bow and arrow, thereby causing the danger of shooting. However, it utilizes the sliding rod 9231 to push against the displacement of the connecting piece 924, and cooperates with the elastic force of the elastic member 925 to pull the connecting piece 924. The overall structure is complicated, the assembly is inconvenient, and the manufacturing cost is high.
