Description

Technical Field

[0001] The utility model belongs to the technical field of immune quarantine laboratories, and particularly relates to a chicken embryo fixer. Background Art

[0002] Chicken embryos are often used for virus inoculation and virus culture in immunological quarantine laboratories or microbiological laboratories. Before inoculation and virus culture, the chicken embryos need to be disinfected and punched. Since the eggs are ellipsoidal, it is difficult to fix them securely and conveniently for punching. Especially when punching in batches, there is no good fixing device, which means that they need to be fixed one by one each time. In addition, the different sizes of chicken embryos also make it more difficult to fix them, which greatly increases the difficulty of operation for the experimenters, wastes time, and increases the difficulty of punching. Therefore, for the operation of disinfecting and punching chicken embryos, it is necessary to design a fixer for fixing chicken embryos for easy disinfection and punching. Utility Model Content

[0003] The utility model aims at the above-mentioned deficiencies of the prior art and invents a chicken embryo fixer.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A chicken embryo fixer comprises a lower box body, a cylindrical hole, a rubber rope, a semi-ellipsoidal shell, a soft inner pad, an upper box body and a soft cover sleeve, wherein the lower box body is provided with 6 cylindrical holes in a rectangular array, a semi-ellipsoidal shell is suspended at the hole opening of the cylindrical hole through a rubber rope; a layer of soft inner pad is provided on the inner surface of the semi-ellipsoidal shell; the lower box body and the upper box body can be installed detachably, a soft cover sleeve is penetrated and embedded in the position of the lower box body corresponding to the cylindrical hole in the upper box body, and the soft cover sleeve is a semi-ellipsoidal sleeve with a hollow interior and an opening on the top.

[0006] The fixer designed by the utility model can meet the fixation requirements of chicken embryos of different sizes under the mutual cooperation of the rubber rope, the semi-ellipsoidal shell, the soft inner pad and the soft cover sleeve. After fixation, the air chamber of the chicken embryo is exposed at the top of the upper box body, and the chicken embryo will not move or shake during disinfection or punching.

[0007] Furthermore, the soft inner pad and the soft cover are made of sponge, which has good softness and resilience and will not break the chicken embryo when squeezed against each other, and can fix the chicken embryo so that it will not slide.

[0008] Furthermore, the shape of the internal hollow space of the soft cover is the same as the shape of the top third of the erected chicken embryo eggshell, and can match the shape and size of the top of the chicken embryo as much as possible to ensure the fixation and stability of the chicken embryo.

[0009] Furthermore, it also includes a connecting buckle, and the lower box body and the upper box body can be detachably installed through the connecting buckle. After placing the chicken embryo in the lower box body, it is only necessary to cover the upper box body to fix the chicken embryo inside, and it is only necessary to move the fixer when moving.

[0010] Furthermore, the connecting buckle includes a fixed connecting strip and a movable buckle strip with the same cross-sectional shape, the fixed connecting strip is fixedly arranged on the left and right sides of the top surface of the lower box body, and the movable buckle strip is rotatably arranged on the top of the fixed connecting strip; the height of the fixed connecting strip is equal to the height of the upper box body, and the upper box body is provided with a through hole passing through the fixed connecting strip; the movable buckle strip can only rotate to an angle of 0 degrees or 90 degrees, so that when it is rotated into place, it is avoided that the fixed connecting strip and the movable buckle strip are misaligned with each other during rotation, resulting in the upper box body being unable to be installed.

[0011] Furthermore, the cross-sectional shape of the connecting buckle is non-circular, so that when the fixed connecting strip and the movable buckle strip are rotated and misaligned, the upper box body and the lower box body can be firmly fixed together.

[0012] Furthermore, the cylindrical hole is a through hole, which is convenient for avoiding the chicken embryo protruding from the top surface of the lower fixture when the two fixtures are stacked together.

[0013] Furthermore, a clearance hole for avoiding the movable buckle strip is provided at the bottom of the lower box body.

[0014] The utility model has the following advantages: the fixer of the utility model can fix chicken embryos of different sizes at the same time under the dual effects of the rubber rope, the soft inner pad and the soft cover sleeve; after the chicken embryos are fixed, only the air chamber on the top is exposed, which is convenient for disinfection or punching; the chicken embryos can be fixed in batches, which speeds up the speed of disinfection and punching of the chicken embryos; the fixers can be stacked together and do not occupy the experimental desktop space, and are also convenient to put into the incubator after punching and inoculation; the overall structure is simple, the production cost is low, the practicability is strong, and it is very suitable for use in inspection and quarantine laboratories or microorganisms.

[0020] The utility model is described in detail below with reference to the accompanying drawings:

[0021] In the description of the present utility model, it should be noted that the directions or positional relationships indicated by "up", "down", "left" and "right" are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, and a specific direction structure and operation, and therefore cannot be understood as a limitation on the present utility model.

[0022] like Figure 1-3 As shown, a chicken embryo fixer comprises a lower box body 1, a cylindrical hole 2, a rubber rope 3, a semi-ellipsoidal shell 4, a soft inner pad 5, an upper box body 6, a soft cover 7 and a connecting buckle 8. The lower box body 1 is a rectangular box body, and six cylindrical holes 2 are arranged in a rectangular array in the lower box body 1, which are arranged in 3 rows and 2 horizontally. A semi-ellipsoidal shell 4 is suspended in the hole of the cylindrical hole 2 through a rubber rope 3; the depth of the cylindrical hole 2 is 8 to 10 cm, ensuring that there is still space at the bottom of the semi-ellipsoidal shell 4 after the largest chicken embryo is placed. A layer of soft inner pad 5 is provided on the inner surface of the semi-ellipsoidal shell 4, and the thickness of the soft inner pad 5 is at least 2.0 cm. The space surrounded by the soft inner pad 5 is mainly used to place the erected chicken embryo, ensuring that chicken embryos of all sizes can be placed and erected. The lower box body 1 and the upper box body 6 can be installed separately, specifically by connecting and installing with a connecting buckle 8; the upper box body 6 adopts a direct vertical downward pressing installation method, and it is not suitable to adopt a flip cover method. A soft cover sleeve 7 is embedded in the lower box body 1 at a position corresponding to the cylindrical hole 2 in the upper box body 6. The soft cover sleeve 7 is a semi-ellipsoidal sleeve with a hollow interior and an open top, so that when the upper box body 6 is covered, the air chamber on the top of the chicken embryo will be exposed on the upper surface of the fixator.

[0023] In order to ensure that the chicken embryo will not be crushed when the box is closed, the soft inner pad 5 and the soft cover 7 are made of sponge, which has good softness and will not slip when in contact with the eggshell. The shape of the internal hollow space of the soft cover 7 is the same as the shape of the top third of the chicken embryo eggshell that stands up, and the area surrounded by the hollow space of the soft cover 7 and the soft inner pad 5 plays a fixing role on the upper and lower ends of the chicken embryo. These two parts are relatively consistent with the shapes of the two ends of the chicken embryo, and their size is based on the small chicken embryo, because the large chicken embryo can be fixed under the extrusion and expansion of the sponge; and the effect of the rubber rope 3 will also be adjusted downward relative to the large chicken embryo, ensuring that the chicken embryo will not be squeezed after the upper box body 6 and the lower box body 1 are closed.

[0024] The connecting buckle 8 includes a fixed connecting strip 81 and a movable buckle strip 82 with the same cross-sectional shape, and the cross-sectional shape is non-circular. The fixed connecting strip 81 is fixedly arranged on the left and right sides of the top surface of the lower box body 1, and the movable buckle strip 82 is rotatably arranged on the top of the fixed connecting strip 81. The movable buckle strip 82 has a rotational activity angle of 0 to 90 degrees. After being rotated into place, there will be a limit and positioning setting, that is, it will be stuck after being rotated into place and will not be easily rotated. The height of the fixed connecting strip 81 is equal to the height of the upper box body 6, and the upper box body 6 is provided with a through hole that passes through the fixed connecting strip 81.

[0025] In order to achieve the mutual superposition of fixers to save storage space or fix chicken embryos in batches, the cylindrical hole 2 is a through hole. After penetration, the exposed chicken embryos in the lower layer can be avoided when the fixers are stacked. The bottom of the lower box body 1 is provided with an avoidance hole 9 for avoiding the movable buckle strip 82.

[0026] Although the specific embodiments of the present invention have been described and illustrated in detail above, it should be noted that various changes and modifications may be made to the above embodiments without departing from the spirit of the present invention and the scope of the appended claims.
