Description
Technical field
The utility model relates to technical field of experiment equipment, and in particular to a kind of fixed device of rat extracting blood.
Background technique
During doing zoopery, often the tail portion of rat is carried out to take blood, is usually used and is caught by hand
The rat mode that blood was collected, but in view of the rat personality that has is excessively fierce, or take to grab mouse mode not right, lead to rat
The event for strongly shaking off the experimenter that even bites occurs, and rat shakes off in blood collection procedure, can not effectively to rat into
Row is fixed, therefore is unfavorable for the progress of blood sampling operation.
Utility model content
The utility model is intended to provide a kind of fixed device of rat extracting blood, with solve in the prior art can not to rat-tail into
The effectively fixed problem of row.
To solve the above-mentioned problems, the utility model provides the following technical solutions: a kind of fixed device of rat extracting blood, packet
Include cabinet, fixed mechanism and driving mechanism, the cabinet is embedded with laterally disposed partition, the partition by the inside of cabinet from
Top to bottm is divided into driving chamber and placed cavity；
The fixed mechanism includes pressure ram, first connecting rod, the second connecting rod and the crushing block for squeezing rat, institute
Pressure ram is stated through partition and is connect with partition vertical sliding, the bottom of the pressure ram is extend into placed cavity, the extruding
Block is fixedly connected with the bottom of pressure ram, and the first connecting rod is laterally arranged, and one end of second connecting rod and first connects
The middle part of extension bar is hinged, and the other end of second connecting rod and the top of pressure ram are hinged, one end of the first connecting rod
Spring is fixedly connected between the inner wall on the left of driving chamber；
The driving mechanism includes iron block, interlocking bar and the electromagnet being fixedly connected with inner wall on the right side of driving chamber, the iron
Block is fixedly connected with the other end of first connecting rod, and the electromagnet and iron block are in same level, the top of the interlocking bar
Portion is fixedly connected with first connecting rod, and the bottom of the interlocking bar and the top horizontal of partition are slidably connected, the interlocking bar position
In the right side of pressure ram；The right side of the placed cavity is opening, and the opening is hinged with door body, and the door body, which is equipped with, is used for mouse
The through-hole that tail passes through.
Working principle of the utility model is: the fixation device in this programme is when in use, door body is opened, is liked using rat
The habit got into the cave, rat are drilled into placed cavity automatically by opening, hold rat-tail and pass through through-hole, are drawn out to it outside door body,
Door body can be closed at this time, realize the isolation to rat.
It also needs that rat is fixed, this programme is achieved in that crushing block at this time is located at the surface of rat, squeezes
Briquetting is fixedly connected with the bottom of pressure ram, and pressure ram is connected with partition vertical sliding, and electromagnet is made to be powered, and electromagnet generates magnetic
Power, because electromagnet and iron block are in same level, iron block is fixed at one end of first connecting rod, and first connecting rod connects
It is connected to vertical interlocking bar, the bottom of interlocking bar and the top horizontal of partition are slidably connected, and interlocking bar can limit the first connection
The direction of displacement of bar, therefore iron block is mobile towards electromagnet under the attraction of electromagnet at this time, while iron block drives the first connection
Bar and interlocking bar are mobile towards the right side of driving chamber, and spring is stretched, and with being gradually increased for elastic force, first connecting rod finally stops
It only moves, iron block and electromagnet do not contact；In this course, because of the top of pressure ram and one end of the second connecting rod hinge
It connects, the other end of the second connecting rod and the middle part of first connecting rod are hinged, and first connecting rod just drives the second connecting rod towards drive
The right side of dynamic chamber is mobile, and in the process of moving, because of the limitation of pressure ram, the second connecting rod is just with itself and first connecting rod
Hinge joint rotates, and the second connecting rod is pressed down against pressure ram, and pressure ram is slided towards placed cavity, is extruded in crushing block greatly
It on the body of mouse, is pressed on rat on the bottom inner wall of placed cavity, realizes the fixation to rat.
Completion carries out tail portion to take blood, after powering off electromagnet, spring-return to nature, pulling first connecting rod,
Second connecting rod and pressure ram are returned to original state.And the size that electric current can be passed through by adjusting electromagnetism electricity in we, come
The magnetic force size that regulating magnet generates, and then control the first connecting rod displacement mobile towards driving chamber, this process
In, iron block and magnet do not contact always, to control the pressure ram displacement mobile towards placed cavity, and then adapt to different building shape
Rat.
The utility model has the beneficial effects that attracting iron block mobile by electromagnet in 1, this programme, and then first is driven to connect
Extension bar is towards moving together, and the second connecting rod, which rotates, makes pressure ram press to rat, and rat is pressed on placed cavity by crushing block
Inner bottom wall on, realize fixation to rat.2, by making electromagnet be passed through different electric currents, electromagnet generates different magnetic
Power to control the pressure ram displacement mobile towards placed cavity, and then adapts to the rat of different building shape.
Further, multiple ventholes are evenly equipped on the placed cavity.Rat can occur in a sealed meter environment it is restless, therefore
Multiple ventholes are set on placed cavity.
Further, the inner wall of the side wall of the crushing block and placed cavity abuts.Setting in this way, crushing block can be complete
The inner bottom wall of all standing placed cavity, bigger to the area coverage of rat, fixed effect is more preferable.
Further, the crushing block bottom is cambered surface.The body of a rat generally cylindrical body, by crushing block
Concave surface is arranged in bottom, and the bottom of crushing block and the contact area of rat body are big, stronger to the fixed function of rat.
Further, the placed cavity is equipped with observation window.The state of rat can be understood in time through observation window.
