Description

A kind of animal trap

The utility model relates to a kind of living animal catcher, comprises following feature: casing, pedal, pedal contact, electromagnet, back-moving spring, connecting rod, push pedal member and revolving door.

Patent Office of the People's Republic of China's " utility model communique " discloses a kind of animal trap, bulletin is 90200248.1, this animal trap is by casing, pedal, pedal contact, electromagnet, back-moving spring, the connecting rod push pedal, revolving door and push pedal contact assembly are formed, weak point is that push pedal contact assembly object is comparatively complicated, pedal contact pick-up current Da Yi scaling loss.

The objective of the invention is to avoid above-mentioned deficiency and longer living animal catcher of simpler life-span of a kind of structure is provided.

Operation principle of the present utility model is to utilize electromagnetic conversion, starts mechanical action.

This practicality is newly by casing, pedal contact, electromagnet, back-moving spring, connecting rod, promote member, revolving door is formed, and electromagnet is by the conducting circuit coil, and circuit coil does work, the moving armature of power supply, hollow magnet steel, contact-carrying and push pedal member are formed, the moving armature axial region of pull bar on the push pedal member and contact-carrying cooperates with the axle center part of hollow magnet steel with the footpath, and both can do axial translation at the axle center part of hollow magnet steel.

When animal touches pedal, the pedal contacting, moving armature by conducting circuit coil contact-carrying, the loop conducting that power supply is formed, the moving armature of contact-carrying is under the effect of electromagnetic force, this armature axial region is in the intracardiac translation of hollow magnet steel, motion puts in place, a termination closing of contact on the acting circuit coil on contact on the moving armature and the acting loop, conducting the acting loop, the moving armature of the contact-carrying facility that do not automatically reset, so promptly be that the pedal contact disconnects, do not influence the acting loop yet and continue action, the acting loop is under the conducting situation, attract the push pedal member, the push pedal member is subjected to magneticaction, pull bar on the push pedal member is attracted translation at hollow magnet steel axle center part, because the same function of current is on two coils of different connections, two opposite gravitation of active force have been produced, pull bar moment on the push pedal member is finished two actions simultaneously, the one, back down the moving armature of contact-carrying, disconnect the acting loop, the 2nd, the pull bar on the attraction push pedal member is in the direction translation of hollow magnet steel axle center part to revolving door.Because the push pedal member links by connecting rod and revolving door, revolving door is opened immediately, the push pedal of forming the push pedal member pushes casing with animal immediately, acting finishes, whole system stream recovers initial closed circuit state, the push pedal member, and revolving door is under the extension spring effect of being fixed on the casing, reset, wait for action next time.

The utility model conducting circuit coil is thin, the turning circuit electric current only satisfies the action of attraction contact-carrying moving armature, electric current is little in the loop, can not burn the pedal contact, acting circuit coil one end and power supply, contact on the contact-carrying moving armature connects, and an end is fixed on the hollow magnet steel, and this fixed position is corresponding with the contact on the contact-carrying moving armature.

Further specify the utility model with regard to accompanying drawing: a kind of living animal is caught device shown in the accompanying drawing, I is the conducting circuit coil among the figure, II is the acting circuit coil, and 1 is the living animal collection box body, and 2 is pedal, the 3rd, the pedal contact, the 4th, hollow magnet steel, the 5th, back-moving spring, the 6th, connecting rod, the 7th, the push pedal member, the 8th, revolving door, the 10th, acting contact, loop, the 11st, the moving armature of contact-carrying, the 9th, the pull bar of push pedal member, the conducting loop is by conducting circuit coil (I), power supply, pedal (2), pedal contact (3) constitutes, the acting loop is by acting circuit coil (II), contact (10), the moving armature of contact-carrying (11), power supply, pull bar on the push pedal member (9) is formed, and acting circuit coil (II) and conducting circuit coil (I) concentric locking collar are contained on the hollow magnet steel (4).

The utility model be provided with between revolving door (8) and the push pedal member (7) pedal (2) when living animal movable to pedal (2), pedal contact (3) contact is closed, make the conducting of conducting loop, conducting circuit coil (I) has electric current to pass through, produce magnetic force, attract the moving armature (11) of contact-carrying to move right along magnet steel (4) hollow shaft, this contact engages with acting contact, loop (10), conducting acting loop, acting circuit coil (II) has electric current to pass through, the pull bar of push pedal member (9) is under the effect of magnetic force, along magnet steel (4) hollow shaft to moving to left, moment is finished two actions simultaneously: the pull bar (9) that drives push pedal member (7) when backing down contact-carrying moving armature (11) moves to left, revolving door (8) links by pull bar (6) and push pedal member (7), revolving door (8) is along with push pedal member (7) moves to left to anticlockwise, setting foot on living animal on the pedal (2) is pushed board member (7) at once and pushes in the collection tank (1), the purpose of collecting living animal reaches, push pedal member (7) resets under the extension spring of being fixed in casing (1) (5) effect, get back to initial de-energized, and close revolving door (8) and wait for action next time.

The utility model conducting loop current is little, and the contact is not burnt out, and is simple in structure, and cost is low, and sensitivity can be widely used in hospital, biological study, and Animal-trapping device the living animal of department such as is butchered and is caught.

Claims (1)

1. A kind of living animal catcher, forming has casing (1), pedal (2), pedal contact (3), back-moving spring (5), connecting rod (6), push pedal member (7), revolving door (8), it is characterized in that being contained in conducting circuit coil (I) on the hollow magnet steel (4) by concentric locking collar, acting circuit coil (II) and the pull bar of doing at the axle center part of hollow magnet steel (4) on moving armature (11) the push pedal member (7) of the contact-carrying of axial translation (9) have been formed electromagnet; By moving armature (11) power supply of contact-carrying, acting circuit coil (II), hollow magnet steel (4), contact (10), push pedal member (7) have been formed the acting loop; Formed the conducting loop by pedal (2), pedal contact (3), power supply, conducting circuit coil (I); The moving armature of contact-carrying (11) axial region matches with the axle center part of hollow magnet steel (4) with the same footpath of the pull bar on the push pedal member (7), does axial translation.
