Abstract

" Nagnetically controlled pedal type continuous mousetrap " is a kind of utensil that is used to catch mouse.Its main feature, promptly be that folding one end at pedal is provided with magnetic means, simultaneously pedal only is restricted to and can be the level of state by sustain pedal around the spring force that axle is connected an end setting with running-board bracket, thereby reduced in the pedal dropping process since the increment of moment shell to the influence of pedal falling speed, the unlatching of pedal is then controlled by magnetic force, accelerate falling speed greatly, reached the effect of " shwoot ".

Description

Nagnetically controlled pedal type continuous mousetrap

" Nagnetically controlled pedal type continuous mousetrap " is a kind of utensil that is used to catch mouse.The method that using appliance kills rats is a lot, but most method once can only be caught one.Existing " pedal mouse cage " is though can continuous capturing, but because the folding of its pedal is controlled by spring fully, falling speed slowly or is slightly touched promptly moving, mouse has timid fear, cunning suspicious, special habits such as agility is flexible, sense of touch sense of smell prosperity in addition, so mouse escapes easily, capturing efficiency is lower.It is the made high efficiency continuous mousetrap of core component by the novel rapidly pedal of can opening and fall after bearing certain gravitational moment that purpose of the present invention promptly is to provide a kind of.

Make pedal fall to being unlikely again rapidly to touch at once a little and open, can solve by magnetic means being set at pedal folding one end.At first, pedal is connected the set spring force of an end with running-board bracket around axle only to be restricted to and can to keep level or smaller by sustain pedal, it is no longer offset the gravitational moment that mouse is produced on pedal, and the increment of moment shell is also very little in the pedal dropping process, influence to the mouse falling speed is also just very small, and the function of giving the pedal auto-closing; Simultaneously magnet and magnetic material are set respectively, it is attracted each other, provide a magnetic torque that makes progress to pedal at pedal folding one end pedal and running-board bracket contact site.According to the magnetic force formula, under the certain situation of field strength, square being inversely proportional to of magnetic force between magnet and the magnetic material and the distance between them.So when the gravitational moment on putting on pedal was less than or equal to magnetic torque, pedal remained static under the effect of magnetic force; And when gravitational moment during greater than magnetic torque, Opening of steps, and along with the increase gradually of opening mouthful, magnetic torque reduces rapidly, and pedal almost completely falls rapidly under the effect of gravitational moment, thereby reaches the effect of " shwoot ".Because of tread length and magnet magnetic force all are definite value, so magnetic torque also became definite value when pedal was closed, and the variation that the gravitational moment that same gravity produced that puts on different parts on the pedal is also faced because of the variation of arm, in a longitudinal direction, gravitational moment is increased to folding gradually by the junction.Mouse is moved to the opening and closing place by the junction on pedal, and when its center of gravity moves to certain position of pedal, gravitational moment just falls rapidly together with pedal during greater than magnetic torque.

According to above principle, make " magnet controlled pedal " (as shown in Figure 1).This pedal by running-board bracket 1., pedal 2., rotating shaft 3., spring 4., 5. magnet form.2. pedal is the ganoid plate object with certain-length and width, makes (as adopting nonmagnetic substance, should adhere to magnetic material at its hole front end and magnet contact site) by magnetic material.Running-board bracket 1. be around pedal 2. around, be used to support and be connected the framework that 2. pedal reaches other parts.1. 3. a pedal 2. end be connected with running-board bracket by rotating shaft, and can 3. rotate flexibly around the shaft.4. spring is enclosed within rotating shaft and 3. goes up, and 2. a moment shell that makes progress is provided 1. for pedal by running-board bracket.Its role is to sustain pedal and 2. be the level of state, and 2. fall behind down to add at pedal and when gravitational moment disappears 2. pedal is restored to the original state, thus its elastic force size can 2. being the level of state or smaller exceeding by sustain pedal, can not be excessive.5. magnet be fixed on the running-board bracket of pedal folding one end and 1. go up (also can be fixed on pedal and 2. go up, 1. running-board bracket sets up magnetic material), its with pedal 2. (or running-board bracket 1.) attract mutually, for 2. pedal provides a magnetic force distance that makes progress.

The body of " Nagnetically controlled pedal type continuous mousetrap " can be a casing (as shown in Figure 2)." magnet controlled pedal " be (hereinafter to be referred as " pedal ") horizontal 1. inner upper part of leaning on of casing of being fixed in 2., and just 1. casing is divided into two Room up and down.Following chamber is a trap chamber, has to enter the room mouth 7. on the front tank wall of pedal shaft one side, and 7. 4. mouse enter trap chamber from the mouth of entering the room by being positioned over the casing outside with the plate of entering the room of mouthful inclination that 7. is connected of entering the room.Can establish mouse trapping port 6. on the tank wall of the casing side of pedal opening one end, seemingly be that passage is with the fascination mouse.On the running-board bracket of pedal opening one end, place bait (not drawing on the figure), lure mouse 2. to pass by from pedal.Following chamber is for being stranded the mouse chamber, and mouse promptly is stranded in this chamber after pedal falls.In the more place of mouse, can establish storage bin in addition 3., 5. the wicket by a unidirectional folding is connected with tired mouse chamber can only advance mouse, can not go out, and other opens one and is convenient to cleaning.Storage bin can be fixedly connected with the mousing casing, also can connect by pipeline, makes storage bin away from the mousing casing, so that camouflage and elimination smell.A tank wall of mousing casing can be made into door or active plugboard, so that place bait and the tired mouse chamber of cleaning.

Like the characteristics of the foot of a wall according to mouse, during seizure, in the place that mouse often haunts, a side that mousetrap is provided with the plate of entering the room gets final product near wall.

Different types of mouse, its height is all different with body weight.But the mouse of same kind, its height and body weight but have certain scope, therefore can be when being definite value according to the pedal magnetic torque, add the vertical excursion of gravitational moment because of what tread length necessarily formed, produce the pedal and the corresponding casing of different model (magnet of different pedal sizes and different magnetic force), to catch different types of mouse.Also can design and produce the large-scale combined mousetrap, to satisfy the needs of under different occasions, place (family, silo, field etc.) condition, catching all kinds mouse (house mouse, Rattus noruegicsu (Berkenhout), field rodent etc.).

Claims (2)

1, a kind of mousetrap has the pedal of a unidirectional folding, the invention is characterized in that pedal folding one end is provided with magnetic means.

2, described in claim 1, the magnetic means of pedal folding one end can be made by loadstone or artificial magnet, also can be made up of electromagnetic component.
