Mouse trap

Technical Field

The invention relates to the technical field of life, in particular to a mousetrap.

Background

Mice are one of four pests, and bring great trouble to the life of people. The current trap commonly used for trapping mice has a mouse trap and a mouse sticking plate. The mouse sticking plate only depends on viscosity to kill the mouse, and is difficult to catch the mouse with larger body, so the mouse killing effect is not good. Although the mouse trap can clamp a mouse, the clamping position of the mouse trap on the mouse cannot be determined, if the mouse trap just clamps the head of the mouse, the clamping of the mouse trap on the mouse is stable, and the mouse cannot escape easily; if the tail of a mouse is clamped by the mouse trap, the mouse can easily escape from the mouse trap, so the success rate of catching by the mouse trap is not one hundred percent.

Although the mouse is caught by the mouse trapping cage, the mouse enters the mouse trapping cage and then is in a free-moving state, when the mouse in the mouse trapping cage is taken, the mouse can escape from an opening of the mouse trapping cage, and the mouse can bite the hands of the taking personnel, so that inconvenience is brought to mouse trapping.

Disclosure of Invention

The invention aims to provide a mousetrap which can prevent a mouse from freely moving when a box body successfully catches the mouse.

In order to achieve the purpose, the technical scheme of the invention is as follows: a mousetrap comprises a box body with an opening at the side part, wherein a heavy plate is vertically and slidably connected to the opening of the box body, a support frame is arranged at the top of the box body, a cross rod and a cross frame are arranged on the support frame, a vertical frame is arranged in the box body, a pedal is arranged on the vertical frame, the middle part of the pedal is rotatably connected to the vertical frame, and a linkage mechanism for controlling the heavy plate to fall is arranged between the pedal and the heavy plate; horizontal sliding connection has the splint of two vertical settings in the box, is equipped with the extension spring between two splint, and vertical sliding connection has the spacing post that can offset with splint in the box, and the vertical sliding connection of opening part of box has the briquetting, and the briquetting is located the below of heavy plate, is connected with the connecting plate between briquetting and the spacing post, is connected with the pressure spring on the connecting plate.

The working principle of the scheme is as follows: when a mouse needs to be caught, the linkage mechanism is in a balanced state under the combined action of the pedal and the heavy plate, the pedal is tilted, the heavy plate is in a suspended state, and the opening of the box body is in an open state. The limiting column is propped against the clamping plate, so that the two clamping plates are separated.

When the mouse entered into the box, the mouse can step on the high-end of pedal, and the pedal takes place to rotate because stepping on of mouse and unbalance, and the pedal touches link gear, and link gear makes heavy board unbalance, and heavy board whereabouts under the effect of self gravity, and the opening part of box is plugged up with heavy board to prevent that the mouse from escaping. Simultaneously, the briquetting is pushed down to heavy board bottom, and the briquetting passes through the connecting plate and drives spacing post downstream, and spacing post is no longer spacing to the splint, and two splint are close to each other under the effect of extension spring, and two splint clip the mouse in the box to prevent that the mouse from being in the active state. Therefore, the mouse is taken out together with the clamping plate, the mouse cannot escape around, and the mouse is convenient to take out of the box body.

The pressure spring is used for enabling the limiting column and the pressing block to reset upwards.

When the technical scheme is adopted, when a mouse enters the pedal in the box body, the heavy plate can automatically fall to block the opening of the box body, so that the mouse is prevented from escaping. Simultaneously, two splint are close to each other, and two splint are cliied the mouse, can prevent that the mouse from fleeing, are convenient for take out the mouse from the box. And, the mouse also can not bite the personnel's of taking hand under the centre gripping of splint, does benefit to the protection personnel of taking.

Further, the link gear includes the balancing pole, first stay cord and second stay cord, be equipped with chucking mechanism between the one end of balancing pole and the crossbearer, chucking mechanism is including rotating the first claw that offsets of connecting on the crossbearer, second of fixed connection on the plain-cross pole supports claw and torsional spring, the torsional spring is connected between first claw and the crossbearer, first claw that offsets can offset with the second claw that offsets, first stay cord is connected between the one end and the heavy plate that the balancing pole kept away from first claw, the second stay cord is connected between step board and first claw that offsets. When the mouse needs to be caught, the first abutting claw and the second abutting claw abut against each other, so that one end, far away from the first pull rope, of the balance rod is fixed, the torsion spring is used for enabling the first abutting claw and the second abutting claw to abut against each other tightly, and the second abutting claw is prevented from falling off from the first abutting claw due to the fact that the balance rod pulls the second abutting claw. Then the middle part of the balancing pole is attached to the cross pole, one end of the balancing pole is fixed by the clamping mechanism, and the other end of the balancing pole is in a static balance state on the cross pole under the action of the pulling of the heavy plate. The first pull rope pulls the heavy plate to enable the heavy plate to be in a suspended state, and the opening of the box body is in an open state. The clamping mechanism pulls the pedal through the second pull rope, so that the pedal is in an inclined state on the vertical frame, one end of the pedal provided with the second pull rope is high, and the other end of the pedal is low. When the mouse entered into the box, the mouse can step on the high-end of trample board, and the trample board takes place to rotate because trampling of mouse, and the trample board touches chucking mechanism through the second stay cord, and chucking mechanism opens, and chucking mechanism no longer fixes the balancing pole, and the balancing pole is out of balance, and the heavy plate falls under the effect of self gravity, and the heavy plate is plugged up the opening part of box to prevent that the mouse from escaping.

The specific implementation process is as follows:

when a mouse is caught, the mouse trap is set as shown in fig. 1: the first abutting claw 39 tightly abuts against the second abutting claw 14 under the action of the torsion spring, the balance rod 15 is arranged on the cross rod at the top of the support frame 17, the balance rod 15 is in a balance state under the fixation of the second abutting claw 14 at the left end and the pulling of the first pull rope 19 at the right end, the heavy plate 26 is in a suspended state under the pulling force of the first pull rope 19, and the opening at the right end of the box body 1 cannot be blocked by the heavy plate 26. The torsion spring has a certain elasticity, so that the second abutting claw 14 is prevented from being separated from the first abutting claw 39 under the pulling of the balance bar 15, and the balance bar 15 is ensured to be in a balanced state. Meanwhile, the first holding pawl 39 pulls the pedal 29 by the second cord 18, the pedal 29 is in an inclined state, the left end of the pedal 29 is high, and the right end of the pedal 29 is low. And the two splints 10 are in an open state under the action of the butting of the limiting columns 8. The elastic band 24 is located above the left end of the first slide bar 22, the elastic band 24 being in tension.

When a mouse with a weight of more than 400g enters the case 1 from the right end of the case 1 along the guide plate 2, the mouse is attracted by the bait, and the mouse climbs the pedal 29 to eat the bait. When the mouse climbs to the left end of the pedal 29, the pedal 29 swings anticlockwise on the vertical frame 28 under the action of the gravity of the mouse, the pedal 29 pulls the right end of the first abutting claw 39 through the second pull rope 18, and the elasticity of the torsion spring is not too large, so that the first abutting claw 39 rotates, according to the weight difference of the mouse, the first abutting claw 39 is pulled by the second pull rope 18 to rotate clockwise around the middle of the first abutting claw 39, so that the left end of the first abutting claw 39 swings to the upper right side, the first abutting claw 39 is separated from the second abutting claw 14, the balance rod 15 loses balance at the moment, the heavy plate 26 slides downwards along the through hole 41 under the action of the self gravity, and the heavy plate 26 blocks the opening at the right end of the box body 1, so that the mouse is prevented from escaping. In the process, because the length of the left side of the balance bar 15 is greater than that of the right side, the force applied to the left side of the balance bar 15 is not too large, and therefore when a mouse steps on the pedal 29, the first abutting claw 39 and the second abutting claw 14 can be easily separated, so that the heavy plate 26 falls off and is sensitive. When heavy plate 26 falls to the bottom of box 1, briquetting 27 is pushed down to the bottom of heavy plate 26, and briquetting 27 drives spacing post 8 downstream through connecting plate 7, and spacing post 8 breaks away from splint 10, and splint 10 are close to each other under the effect of extension spring 9, and two splint 10 clip the mouse to prevent the mouse activity. Meanwhile, the connecting plate 7 presses the air bag 3 downwards, the air bag 3 contracts, air in the air bag 3 enters the air pressure cavity 32 of the piston cylinder through the air pipe 33, the air pressure in the air pressure cavity 32 is increased, the piston 31 slides leftwards under the action of the air pressure, and the piston 31 instantly sprays anesthetic in the liquid cavity 30 to the tip of the bottom of the striker 25 through the spray pipe 34. And, in the process that the two clamping plates 10 approach each other, as shown in fig. 5, the two clamping plates 10 drive the two vertical rods 11 to approach each other in the bar-shaped holes 40, the two vertical rods 11 drive the diamond-shaped frame to deform, the diamond-shaped frame lengthens in the left and right directions, the right end of the diamond-shaped frame abuts against the left end of the second slide rod 20, the right end of the diamond-shaped frame pushes the second slide rod 20 to move rightwards, the right end of the second slide rod 20 abuts against the clamping block 21 and pushes the first slide rod 22 to move rightwards, the left end of the first slide rod 22 disengages from the elastic belt 24, the elastic belt 24 ejects downwards under the action of the self elasticity, the elastic belt 24 ejects the striker 25 adhered on the supporting plate 23, and the striker 25 ejects out of the head of the mouse impacting downwards through the through hole 43, thereby. In addition, since the anesthetic is adhered to the bottom of the striker 25 and the bottom end of the striker 25 is a tip end, even if the striker 25 does not strike the head of the mouse but the striker 25 strikes other parts of the mouse, the tip end of the striker 25 can stab the skin of the mouse, and the anesthetic can enter the mouse body through the wound to unconscious the mouse, thereby facilitating the removal of the mouse by a small person.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, it is possible to make various changes and modifications without departing from the concept of the present invention, and these should be construed as the scope of protection of the present invention, which will not affect the effect of the implementation of the present invention and the utility of the patent.
