Reference numeral: 1 cylindrical shell 2 plugs 3 are separated a projection 4 Mus locating hole 5 spacing block 6 chute 7 fastening cover 8 bolt 9 fixed leg 10 link slot 11 packing ring 12 groove 13 through hole 14 entrance 15 guide plate 16V shape gathering sills.
The specific embodiment
Experimental rat stationary magazine creel described in the utility model, comprises cylindrical shell 1 as shown in Figure 1.The front end of cylindrical shell 1 is offered entrance 14, the back-end sealing of cylindrical shell 1.The interior movable plug 2 of installing of cylindrical shell 1.As shown in Figure 3 and Figure 4, plug 2 bottom surface medium positions are provided with spacing block 5.Plug 2 is offered a Mus locating hole 4 along the length direction of cylindrical shell 1.A Mus locating hole 4 is pre-small post-large holes, to meet the profile of mouse head, both can better locate, and can alleviate the sense of discomfort of mice again as far as possible, is conducive to experiment and carries out smoothly.The front portion of a Mus locating hole 4 is through hole 13, facilitates mouse breathing.Projection 3 is separated in the interior fixed installation of cylindrical shell 1, separates projection 3 and is positioned at cylindrical shell 1 centre position, bottom surface, and be positioned at spacing block 5 rears.Spacing block 5 can make mouse head stretch into after a Mus locating hole 4, and two forelimbs of mice are separated piece 5 and separate, and the forelimb of mice can not touched.Separate projection 3 and can make the hind leg of mice lay respectively at separation projection both sides, avoid mouse hind leg to touch.Separate projection 3 corresponding with spacing block 5, to mice correctly can be located, guarantee that its blood circulation is normal.As shown in Figure 1, cylindrical shell 1 end face is offered chute 6 along its length.As shown in Figure 2, link slot 10 is offered at the middle part of cylindrical shell 1 rear end, and the top of link slot 10 communicates with the rear end of chute 6.This structure can make that the tail of mice is flat stretches out cylindrical shell 1, avoids mousetail to go wrong because of the curling blood circulation that causes, thereby, convenient injection or get blood on the tail of mice.The front end of chute 6 communicates with entrance 14.As shown in Figure 2, chute 6 and link slot 10 form a L shaped Mus tail gathering sill.The effect of Mus tail gathering sill is: when staff puts into entrance 14 by mice, make the afterbody of mice can comparatively successfully slip into chute 6, along with mice moves down along cylindrical shell 1, Mus tail can slide in link slot 10 by nature, reach mice in cylindrical shell 1, Mus tail stretches out the object outside cylindrical shell 1, thereby, can solve that prior art exists that mice is put into container contents is easy, Mus tail is exposed to the outer difficult problem of container.Described stationary magazine creel can significantly simplify fixedly mice and the work of taking out Mus tail, can effectively save experimental period, improves conventional efficient.Observe for convenience the situation of mice in cylindrical shell 1, cylindrical shell 1 can select transparent material to manufacture.
The fixing process of experimental rat:
1. by the interior taking-up plug 2 of cylindrical shell 1, by mice with head afterbody direction backward forward, by entrance 14, put into cylindrical shell 1, and make mouse back towards chute 6, when mice enters entrance 14, its afterbody can enter in chute 6 by nature, by pulling Mus tail, mice can be pulled to smoothly to cylindrical shell 1 bottom, by pulling Mus tail to move mice, than traditional, push away mice to enter container more easy to operate, mice is also difficult for struggling.
While 2. mice being moved to cylindrical shell 1 rear end, Mus tail is stretched out outside cylindrical shell 1 by link slot 10, now, cylindrical shell 1 can be holded up, mice cannot be climb along smooth barrel, plug 2 is reentered in cylindrical shell 1, mouse head enters in a Mus locating hole 4, with detent mechanism, by plug 2 and cylindrical shell 1 locking, be about to mice locking.Mice is in cylindrical shell 1, and owing to separating the effect of projection 3 with spacing block 5, therefore, mice cannot be overturn in cylindrical shell 1, conveniently tests.
As shown in Figure 2, described locking mechanism can be connected and composed by bolt 8 and fastening cover 7.One end of plug 2 threaded connection bolts 8, the other end of bolt 8 is through chute 6 fixed installation fastening covers 7.This structure coordinates the locking position of plug 2 by fastening cover 7 and cylindrical shell 1, thereby, can adjust according to mice body size the latched position of plug 2, convenient mice of fixing any bodily form.Described locking mechanism can also be the mechanism that alignment pin and locating hole coordinate, and still, the adjusting range of this mechanism is limited, is difficult to accurately adjust the position of plug 2.After mice is fixing, or it is excessive to be stressed, or too loose, all can directly affect experiment effect.
A described plug 2 bottoms side relative with separating projection 3 offered groove 12, and groove 12 communicates with a Mus locating hole 4.The physiological structure fit of this structure and mice can not struggled because health is squeezed mice in experiment.Groove 12 also can play the guiding role to mice, facilitates mice that head is put in to a Mus locating hole 4.
For convenience of being fixedly connected with experimental facilities, on the outer wall of described cylindrical shell 1 chute 6 both sides, several fixed legs 9 can be installed respectively.This structure facilitates cylindrical shell 1 and corresponding equipment to fix.
Described fastening cover 7 lower ends arrange packing ring 11, and packing ring 11 is arranged on bolt 8, and packing ring 11 is positioned at chute 6 tops.When this structure is slided plug 2, avoid fastening cover 7 and cylindrical shell 1 to produce friction, thereby cause fastening cover 7 wearing and tearing, the service life of having improved fastening cover 7.
The front end of described cylindrical shell 1 is pre-large post-small gradually-reducing shape, to mice can be put into cylindrical shell 1 smoothly.For further increase put mice while entering cylindrical shell 1 Mus tail enter the probability of chute 6, guarantee simple and efficient to handlely, as shown in Figure 1, the end face of the front end of described cylindrical shell 1 is offered V-arrangement gathering sill 16, V-arrangement gathering sill 16 communicates with chute 6.Cylindrical shell 1 bottom surface of V-arrangement gathering sill 16 correspondences is provided with guide plate 15.Guide plate 15 can assist mice to enter in cylindrical shell 1.
The technical solution of the utility model is not restricted in the scope of embodiment described in the utility model.This utility model not technology contents of detailed description is known technology.
