Limit assembly 6 includes the first spring 61, cylinder 62 and hemisphere 63, the first sliding block 14 in first sliding groove 22 in sliding process,
First sliding block 14 can be inconsistent with hemisphere 63, then generates pressure effect to hemisphere 63；Under pressure, the first spring
61 will deformation occurs, such hemisphere 63 will enter in limiting slot 23, continue to slide convenient for the first sliding block 14；When
When one sliding block 14 is to hemisphere 63 is acted on without pressure, the first spring 61 will reply deformation, in the elastic force of the first spring 61
Under effect, hemisphere 63 exposes outside limiting slot 23 again；First sliding block 14 will be limited in hemisphere 63 and first sliding groove 22
Between inner wall, it ensure that rearging cage 1 is completely embedded with rack 2, it is not easy to be detached from；But it is raised by being pulled with biggish pulling force
When cage 1, rearging cage 1 still can be separated mutually with rack 2, will not influence the subsequent test to experimental animal；By by
The cross section of one sliding block 14 is arranged to circle, generates preferable pressure to hemisphere 63 convenient for the first sliding block 14 and acts on, is separating
It is more easy and convenient when rearging cage 1 and rack 2.
It further include having alarm assemblies 7, the alarm assemblies 7 are located at rack 2 as a kind of improved specific embodiment
On；The alarm assemblies 7 include temperature detect switch (TDS) 71 and alarm device 72, and the temperature detect switch (TDS) 71 is coupled with alarm device 72；Work as temperature
When being greater than the set value, temperature detect switch (TDS) 71 is closed, and alarm device 72 is alarmed.
By being provided with alarm assemblies 7, alarm assemblies 7 include temperature detect switch (TDS) 71 and alarm device 72, when placement is of the invention
It has been more than the setting value of temperature detect switch (TDS) 71 when laboratory temperature is excessively high, temperature detect switch (TDS) 71 will be closed, and temperature detect switch (TDS) 71 is closed
Afterwards, alarm device 72 just will call the police, to be conducive to the temperature that experimenter takes certain measure to reduce laboratory, guarantee in laboratory
Property safety, experiment progress will not be influenced.
As a kind of improved specific embodiment, the rack 2 and the bottom of pressure fan 31 are provided with universal wheel
24。
Through the above technical solutions, by being provided with universal wheel 24, convenient for the mobile rack 2 of experimenter and pressure fan
31, it is tested so that rack 2 is placed on suitable position with pressure fan 31, guarantees the accuracy and validity of experiment.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
Those of ordinary skill for, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
