The purpose of this utility model and solve it and technical problem is that and realize by the following technical solutions.Device according to the simulation mouse hind leg weightlessness that the utility model proposes, include rearging cage, belt pulley, Universal rotary change, chain and adhesive plaster, described belt pulley is two, it is connected by connecting rod between two described belt pulleys, described belt pulley is arranged on the inner tip of described rearging cage, described Universal rotary change is movably arranged on the top of connecting rod, and the bottom of described Universal rotary change is connected by chain adhesive plaster, the hind leg of described immobilization with adhesive tape experimental subject.
Further, the device of aforesaid simulation mouse hind leg weightlessness, described Universal rotary change includes rotating ring, lower rotating ring and rotation portion, described upper rotating ring is connected by rotation portion with lower rotating ring, described upper rotating ring is connected with described connecting rod, and described lower rotating ring is connected with chain.
Further, the device of aforesaid simulation mouse hind leg weightlessness, described upper rotating ring and lower rotating ring relatively rotate 0 ° ~ 360 °.
Further, the device of aforesaid simulation mouse hind leg weightlessness, a side bottom at described rearging cage is provided with water fountain, and another side bottom of described rearging cage is provided with crib.
Further, the device of aforesaid simulation mouse hind leg weightlessness, the base plate of described rearging cage is additionally provided with flat board.
Further, the device of aforesaid simulation mouse hind leg weightlessness, described flat board is the slab construction of drawer type.
Further, the device of aforesaid simulation mouse hind leg weightlessness, described outer pulley surface is provided with groove, and described belt pulley makes a concerted effort to be fixed on rearging cage top by the card of groove, and along rearging cage top fixing rod direction slidably.
Further, the device of aforesaid simulation mouse hind leg weightlessness, the bottom water outlet of described water fountain is provided with curved mouth.
By technique scheme, the device of simulation mouse hind leg weightlessness of the present utility model at least has the advantage that
The device of simulation mouse hind leg weightlessness of the present utility model; the hind leg of experiment mice is fixed by medical proof fabric; and belt pulley can be slidably; ensure that mice normal activity in rearging cage; toy curved mouth water fountain fixing in rearging cage and spoon type crib; facilitate mouse diet, the drawer type flat board easy cleaning Excreta of bottom, the impact on experimental result of the external interference factor can be got rid of on the basis of ensureing experiment mice orthobiosis.And the firm practicality of this apparatus structure, volume is little, easy cleaning, low cost, and mice activeness is good, and infection rate, mortality rate are low, can stably realize utilizing the purpose of mice simulation hind leg weightlessness.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be practiced according to the content of description, below with preferred embodiment of the present utility model and coordinate accompanying drawing describe in detail as after.
