Detailed Description

The technical solutions of the present invention will be explained and illustrated in detail below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it.

The utility model discloses a baoding device includes braced frame 1, sets up at braced frame 1's top and extend braced frame 1 arrange on one side and with U type bed 5 and the U type support frame 6 that this limit is connected, along the enclosure frame 2 of braced frame 1's top periphery setting, set up at braced frame 1's top and with U type bed 5 and U type support frame 6 along braced frame 1's limit parallel arrangement's fastening frame 4. The fastening frame 4 is connected to a driving mechanism 3, and the driving mechanism 3 can drive the fastening frame 4 to move back and forth by a driving rod. The U-shaped bed 5 is fixedly connected with the supporting frame 1, and the U-shaped supporting frame 6 can slide on the supporting frame 1, so that the distance between the U-shaped bed 5 and the U-shaped supporting frame can be adjusted. For example, two U-shaped supporting frames 6 are respectively disposed on two sides of the U-shaped bed 5, and the two U-shaped supporting frames 6 can slide along one side of the supporting frame 1, so as to adjust the distance between the two U-shaped supporting frames 6 and the U-shaped bed 5.

The support frame 1 serves to stabilize the structure of the entire holding device, and its height can also be adjusted for easy handling. The drive rod may pass through the rim of the enclosure frame 2 and be threaded thereto so that the position of the fastening frame 4 can be adjusted by rotating the drive rod. The fastening frame 4 is a back side enclosure in the horizontal direction, and the limited space can be adjusted according to different body types of animals. Further, the enclosure frame is detachable except for the portion connected with the fastening frame 4, thereby facilitating the operator to place the animal on the U-shaped bed 5. For example, the frame of the enclosure frame corresponding to the U-shaped portion of the U-bed 5 is removable, while the frame corresponding to the platform portion is not removable. In practice, the removable frame may be opened first to facilitate the placement of the piglets on the U-bed, and then the removed frame may be attached for subsequent operations, or some operations may be performed over a portion of the frame.

A sprocket may be fixed to one end of the driving rod, and a plurality of sprockets are linked by a chain, so that the fastening frame 4 travels uniformly in parallel. Namely, the chain wheel and the chain are used for effectively adjusting the extrusion of the fastening frame, and the synchronous compression of the two ends of the fastening frame is realized through the rocker. The fastening frame is adjusted by driving the rocker in a manual mode, and an electric mode can be adopted to replace a hand-operated mode.

The support frame 1 may be provided with a tray below for collecting the baby pig excretions, and rollers, such as silent wheels, may be provided at each corner of the support frame 1 to facilitate the transfer. One side (for example, the front side) of envelope is can outwards be opened from the upside, is convenient for put into U type bed with the animal such as little pig, and envelope's both sides frame is the detachable construction who takes the slot, can select to install or dismantle the envelope of both sides according to little pig's size and operation needs.

The U-shaped bed can be a structure used for the animal such as the miniature pig to lie prostrate, and the U-shaped supporting frames at the two sides of the U-shaped bed can be adjusted back and forth in the slide ways according to the size of the miniature pig, and the miniature pig lies prostrate on the U-shaped bed. Back binding bands can be arranged on the enclosure frame, so that the arch backs of the miniature pigs are prevented, the four limbs of the miniature pigs are perpendicular to the lower portion of the bed, and then the test operation is carried out. The U-shaped bed 5 and the U-shaped support frame 6 each have a platform portion and a U-shaped portion, and the top of the inside of the enclosure frame is provided with a fixing rod parallel to the platform portion, which can pass through the fastening frame 4 and allow the fastening frame 4 to slide along the fixing rod on the platform portion.

After the piglet is fixed completely, can require to keep the operation of longer time according to experimental operation, like continuous intravenous infusion test object, or gather blood sample etc. many times, hand-held assistance baoding animal of need not personnel, only need personnel alone to patrol, pacify the adjustment to individual animal, compare with conventional baoding hammock, neotype baoding device baoding is more firm, more is fit for long-term operation, has also reduced assistance baoding personnel, provides test efficiency.

Although various embodiments have been disclosed above, they have been used and are to be interpreted in a generic and descriptive sense only and not for purposes of limitation. In some instances, features, characteristics and/or elements described with respect to an embodiment may be used alone or in combination with features, characteristics and/or elements described with respect to other embodiments, unless specifically indicated otherwise, as will be apparent to one of ordinary skill in the art. It will therefore be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention.
