Abstract

The utility model discloses a hepatitis delta virus model teaching aid, comprising a circular ring-like body and an annular centrebody arranged in the body, wherein the body is formed through annular connection of nine first split parts, five second split parts and ten third split parts, two bead strings are in tandem with the centrebody, each bead string comprises two first stringing beads and two second stringing beads, and the two second stringing beads are arranged between the two first stringing beads. The teaching aid provided by the utility model employs a dismounting and mounting structure, which enables a packaging volume to be reduced and strengthens memory of a user.

Description

A kind of Hepatitis D virus model teaching aid

Technical field

The utility model relates to a kind of model teaching aid, relates in particular to a kind of Hepatitis D virus model teaching aid.

Background technology

Hepatitis D virus (HDV) is defective virus, need bite liver DNA virus, as the help of helper viruses such as viruses of human hepatitis B (HBV), alpine marmot hepatitis virus and dhbv dna, just can become ripe virion and have infectivity.Hepatitis D virus (HDV) is unique defective virus with single minus strand virus covalently closed circular rna gene group in the present known animal virus, and some characteristic is similar to satellite viruses in plants or viroid.

The Hepatitis D virus of complete maturation (HDV) is spheric grain, coating is HBsAg, nucleocapsid is the icosahedron symmetry, virion inside is made up of the Hepatitis D virus antigen (HDAg) of virus genome RNA and combination with it, and its outsourcing is with the coat protein of the HBsAg(hepatitis B of HBV).

In general teaching, in order to represent the primary structure of Hepatitis D virus (HDV), generally all use sectional view to explain as pattern, but because sectional view is the plane, the CONSTRUCTED SPECIFICATION that can not well represent Hepatitis D virus (HDV) is so need the model of a three-dimensional to assist explanation.

Summary of the invention

The purpose of this utility model provides a kind of Hepatitis D virus model teaching aid of reassembling type.

For achieving the above object, the technical solution adopted in the utility model is: a kind of Hepatitis D virus model teaching aid, it comprises circular body, be placed on described intrinsic ring center body, described body is formed by connecting by 9 first splits, 5 second splits, 10 triad annulars, be connected with two groups of pearl strings on the described centrosome, described pearl string comprises two first beading and two second beading, and two described second beading are arranged between two described first beading.

In the technique scheme, first split, second split, triad can be distinguished with different colours and represent, also can adopt difformity to distinguish expression.First beading and second beading can be distinguished with different colours and represent, also can adopt difformity to distinguish expression.

Optimized technical scheme, described centrosome are a closed hoop, and described first beading, second beading are provided with the bayonet socket that cooperates with described centrosome, and described first beading, second beading are stuck on the described centrosome by described buckle.

Optimized technical scheme, but described centrosome is the folding ring, described first beading, the second beading center are provided with perforation, and described first beading, second beading are worn and are connected on the described centrosome.

Further technical scheme, two openends of described centrosome are provided with buckle, and described centrosome is closed into ring by described buckle.

Optimized technical scheme, described first split, second split, triad are respectively arranged with the buckle structure that matches on relative two sides.

Because technique scheme is used, the utility model compared with prior art has following advantage:

What the utility model adopted is the 3 D stereo disassembly and assembly structure, not only can save transport space, reduces transportation cost, can also increase user's manipulative ability, enhances memory, and understands the architectural feature of Hepatitis D virus more in depth.

Fig. 3 is embodiment two stereographic maps;

Fig. 4 is embodiment one exploded view.

Wherein: 1, body; 2, centrosome; 3, first beading; 4, second beading; 5, first split; 6, second split; 7, triad.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described:

Embodiment one:

Shown in Fig. 1-2, a kind of Hepatitis D virus model teaching aid, it comprises circular body 1, be placed on intrinsic ring center body 2, body 1 is formed by connecting by 9 first splits 5,5 second splits 6,10 triad 7 annulars, be connected with two groups of pearls string on the centrosome 2, the pearl string comprises that second beading 4 of 4, two of two first beading 3 and two second beading are arranged between two first beading 3.

Centrosome 2 is a closed hoop, and first beading 3, second beading 4 are provided with the bayonet socket that cooperates with centrosome 2, and first beading 3, second beading 4 are stuck on the centrosome by buckle.

First split 5, second split 6, triad 7 are respectively arranged with the buckle structure that matches on relative two sides.

First split 5, second split 6, triad 7 adopts difformities to distinguish expression, and first split 4 is cube, and second split 6 has the cube of strip projected parts for upper surface, and triad 7 has the cube of T shape projection for upper surface.

First beading 3 are spheroid, and second beading 4 are spheroid.

Hepatitis D virus (HDV) capsid HDAg is a kind of nucleoprotein, is unique albumen of HDV coding.By ORF5 coding in the anti-genome of normal chain, P24 and P27 two peptide species are arranged, be respectively big delta antigen and little delta antigen.The former is to the transactivation that copied of HDV, and the latter then trans inhibition copies effect, and the packing of HDV is also had significant effects.About 60 HDAg are combined with a HDV geneome RNA, constitute the nucleocapsid of icosahedron symmetry.

Each structure member contrast of each parts and Hepatitis D virus in the present embodiment:

Body 1 represents Hepatitis D virus (HDV) coating HBsAg, and the pearl string represents Hepatitis D virus antigen (HDAg), and first beading 3, second beading 4 represent P24, P27 two peptide species respectively.

In the present embodiment, each parts all adopts dismantled and assembled structure, can make the user understand the architectural feature of Hepatitis D virus (HDV) more and enhances memory.
