All the alarming triggers of animal traps, as a rule, contain some kind of sensitive element of the gatehouse, a spacer or a clamp, which are under load and hold this load.
The guarded latches and triggers of animal traps using rocker arms, strut sticks, spacer bars, easily pulled out loops, rings and pegs.
In the event of the force acting on another sensitive element, the guard of the trap of no animals, for example, a stretch, the trigger activates and ceases to hold the load, the balance is disturbed and the trap is activated.
Types of triggers, gatekeepers, struts and catchers of traps on animals.
1. Hook type trap latch.
It is a hook hooked on a notch in the support, it works only in the direction perpendicular to the applied force. The disadvantage is the difficulty of uncoupling the extension and the triggering mechanism on the hook itself. It is used either in traps, where it doesn’t matter, mainly in snares, or with the expectation that the pegs holding the stretch pegs will be pulled out, or the release mechanisms are introduced. The advantage is ease of manufacture.
12. Trigger triggers in which rope loops and knots are held by easily pulled pegs.
All of these devices are quite simple, but for the most part they are somewhat taut on the descent. When manufacturing, it must be remembered that the shape of the pegs should be conical, and their surface should be smooth, and they should not be inserted very deep. Problems with tripping of structural elements during operation usually do not arise.
