Abstract
The utility model provides an animal fixator comprising an animal fixing chamber and a fixing piston mounted in the same. The fixing piston comprises a seal head, a push bar, a push bar movement hole, a pull bar, and a pull bar fixing device; the pull bar movement hole is arranged in the axial portion of the push bar; the pull bar is disposed in the pull bar movement hole; the pull bar fixing device is used for fixing the pull bar. The pull bar is fixedly connected with the seal head. The first end of the push bar is in contact connection with the seal head. The seal head is stressed by pull of the pull bar, the pull bar is fixed by the pull bar fixing device, the seal head and the animal fixing chamber are in interference fit, and sealing is achieved. The seal head cannot move in the animal fixing chamber, so that an animal can be fixed. When the seal head needs to be moved or the piston needs to be removed, the seal head is restored first, a large gap between the seal head and the animal fixing chamber allows the piston to move conveniently, and the piston can be moved in a piston cylinder with little effort; meanwhile, sealing performance is excellent.

animal holder of the present utility model, the fixed piston by setting with sealing head and pull bar fixing device, pull bar produces pulling force and makes sealing head pressurized, pull bar fixing device fixed drawing-rod, sealing head and animal lock chamber interference fit, play seal action, and due to interference fit, sealing head can not move in animal lock chamber, plays the fixedly effect of animal.When needs hydrodynamic reciprocating sealing head or taking-up piston, first make sealing head restore to the original state, between sealing head and animal lock chamber, there is larger gap, be convenient to the movement of piston, make piston move and not need very large strength in piston barrel, and sealability is outstanding.
according to the detailed description to the utility model specific embodiment by reference to the accompanying drawings below, those skilled in the art will understand above-mentioned and other objects, advantage and feature of the present utility model more.
Accompanying drawing explanation
hereinafter in exemplary and nonrestrictive mode, describe specific embodiments more of the present utility model in detail with reference to the accompanying drawings.In accompanying drawing, identical reference character has indicated same or similar parts or part.It should be appreciated by those skilled in the art that these accompanying drawings may not draw in proportion.In accompanying drawing:
fig. 1 is according to the schematic perspective view of an embodiment's of the utility model animal holder;
fig. 2 be the animal holder shown in Fig. 1 schematic right parallax stereogram;
reference character: animal lock chamber 10, gradually-reducing shape cavity 11, circular cylindrical cavity 12, fixed piston 20, sealing head 21, push rod 22, pull bar 23.
Embodiment
fig. 1 is according to the schematic perspective view of an embodiment's of the utility model animal holder, Fig. 2 be the animal holder shown in Fig. 1 schematic right parallax stereogram; As depicted in figs. 1 and 2, a kind of animal holder, comprises animal lock chamber 10 and is arranged on the fixed piston 20 in described animal lock chamber 10.The head end of animal lock chamber 10 is gradually-reducing shape cavity 11, and the tail end of animal lock chamber 10 is circular cylindrical cavity 12, and fixed piston 20 is arranged in circular cylindrical cavity 12.The pull bar that fixed piston 20 comprises sealing head 21, push rod 22, be arranged on the central axis of push rod 22 moves hole and is positioned at that pull bar moves the pull bar 23 in hole and for the pull bar fixing device of fixed drawing-rod 23; Pull bar 23 is fixedly connected with sealing head 21, and the first end of push rod 22 is connected with sealing head 21 contacts.Sealing head 21 is after pressurized, and the diameter of outermost one circle of sealing head 21 becomes large.Working procedure is, takes out fixed piston 20, and the animals such as mouse are put in animal lock chamber 10 from the tail end of animal lock chamber 10, and the head of mouse is placed in gradually-reducing shape cavity 11, and the sealing head 21 of fixed piston 20 is arranged on the tail end of mouse.Put into after animal, fixed piston 20 advances animal lock chamber 10, and the diameter of sealing head 21 outmost turns is less than the diameter of circular cylindrical cavity 12, at an easy rate fixed piston 20 is shifted onto to the tail end of animal; Keep the position of sealing head 21 motionless, pull bar 23 and push rod 22 are relatively moved, press seal head 21, sealing head 21 pressurizeds, the diameter of sealing head 21 outmost turns becomes greatly gradually, and circular cylindrical cavity 12 interference fit.Now pull bar fixing device is not moving pull bar 23, fixed drawing-rod 23, and sealing head 21 and animal lock chamber 10 interference fit, play seal action, and due to interference fit, sealing head 21 can not, in the interior movement of animal lock chamber 10, play the fixedly effect of animal.When needs hydrodynamic reciprocating sealing head 21 or taking-up piston, first make sealing head 21 restore to the original state, between sealing head 21 and animal lock chamber 10, there is larger gap, be convenient to the movement of piston, make piston move and not need very large strength in piston barrel, and sealability is outstanding.
