Description
Technical field
The utility model relates to field of suspension devices more particularly to a kind of novel algebra chart suspension arrangements.
Background technique
It during Algebra Teaching, often needs to carry out illustrated to the coordinate graphic of algebra, be needed at this time using to figure
Table, traditional chart are mostly used to be pasted on blackboard and be shown or using lantern slide exhibition, be easy to damage blackboard or
It is not available in no equipment, use is not convenient enough.
Utility model content
The utility model In view of the above shortcomings of the prior art, it is outstanding to provide a kind of structurally reasonable novel algebra chart
Hang device.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of novel algebra chart suspension arrangement, including pressing plate, fixed station, algebra chart, fixing bolt, in the pressing plate
Portion has a locating convex block slot, pressing plate internal symmetry Distribution and localization column slot, is uniformly distributed tooth socket inside positioning column slot, right inside pressing plate
Claim distribution internal thread hole, there is locating convex block outside the fixed station, fixed station outer symmetrical Distribution and localization column, outside positioning column
It is uniformly distributed external tooth, there is internal thread groove inside positioning column, there is locating convex block through-hole, algebra chart inside the algebra chart
Internal symmetry Distribution and localization column through-hole is uniformly distributed flute profile hole inside positioning column through-hole, and locating convex block is sequentially inserted into locating convex block
In through-hole and locating convex block slot, positioning column is sequentially inserted into positioning column through-hole and positioning column slot, and tooth socket, external tooth and flute profile hole are mutual
Cooperation.
The symmetrical sucker in fixed station rear portion, sucker and blackboard surface are attracted, and tooth socket is cooperatively formed with internal thread groove
Tightly, pressing plate is connect with fixed station for fixed thread chamber, fixing bolt and fixed thread chamber, and algebra chart lower part has chart
Body.
The utility model has the advantages that
Locating convex block is sequentially inserted into locating convex block through-hole and locating convex block slot, while playing positioning action, contact
Face is irregular rectangle and inclined-plane, can uniformly bear play load, make stable connection, structurally reasonable, external tooth is sequentially inserted into
In flute profile hole and tooth socket, while playing the role of being located by connecting, contact surface is flute profile, can uniformly bear rotation load and alter
Dynamic loading makes structurally reasonable, the symmetrical sucker in fixed station rear portion, and sucker and blackboard surface are attracted, and will not remain viscose, structure
Rationally.

Specific embodiment
The utility model is described in further detail below according to drawings and examples:
A kind of novel algebra chart suspension arrangement, including pressing plate 01, fixed station 02, algebra chart 03, fixing bolt 04, institute
Stating has locating convex block slot 11 inside pressing plate 01,01 internal symmetry Distribution and localization column slot 12 of pressing plate, and 12 inside of positioning column slot is uniformly
It is distributed tooth socket 13,01 internal symmetry of pressing plate is distributed internal thread hole 14, has locating convex block 21, fixed station outside the fixed station 02
02 outer symmetrical Distribution and localization column 22 is uniformly distributed external tooth 23 outside positioning column 22, has internal thread groove 24 inside positioning column 22,
There is locating convex block through-hole 31,03 internal symmetry Distribution and localization column through-hole 32 of algebra chart, positioning inside the algebra chart 03
Flute profile hole 33 is uniformly distributed inside column through-hole 32, locating convex block 21 is sequentially inserted into locating convex block through-hole 31 and locating convex block slot 11
Interior, positioning column 22 is sequentially inserted into positioning column through-hole 32 and positioning column slot 12, and tooth socket 13, external tooth 23 and flute profile hole 33 mutually match
It closes.
The symmetrical sucker 25 in 02 rear portion of fixed station, sucker 25 and blackboard surface are attracted, tooth socket 13 and internal thread groove
24 cooperatively form fixed thread chamber, fixing bolt 04 and fixed thread chamber tightly, and pressing plate 01 is connect with fixed station 02, the algebra
03 lower part of chart has chart body 34.
