Abstract
The utility model discloses a hyperbola quick drawing template which comprises a rectangular flat board and is characterized in that a dovetail groove is arranged on the central line of the rectangular flat board; a straight line-shaped through hole is arranged on the central line of the dovetail groove; a dovetail slide block is arranged in the dovetail groove; a chalk sleeve is fixed in a central through hole of the dovetail slide block, and a chalk is embedded into the chalk sleeve; the rectangular flat board at the two sides of the dovetail groove is provided with through holes meeting the standard of a hyperbola; telescopic rotary rods are arranged at the two sides of the dovetail slide block; chalk sleeves used for drawing the hyperbola are fixed at the end parts of the telescopic rotary rods and are inserted into the through holes meeting the standard of the hyperbola; chalks used for drawing the hyperbola are embedded into the chalk sleeves used for drawing the hyperbola; and tension springs are arranged at the inner sides of the telescopic rotary rods. According to the hyperbola quick drawing template, the hyperbola is templated, and the dovetail slide block connects the chalk used for drawing the straight line and the chalks used for drawing the hyperbola into a whole to slide together, so that the hyperbola quick drawing template can draw the standard hyperbola quickly and accurately.
Description
Technical field
The utility model relates to a kind of mathematical education teaching aid, and specifically a kind of hyperbolic linear speed is drawn template, is applicable to several teaching.
Background technology
Planar, the track that the absolute value of the difference of the distance of two fixed points equals the point of constant is called hyperbola, meets the hyperbola normal equation, so, when on blackboard, drawing hyperbola, think the very accurately very difficult of picture.At present, drawing hyp method generally is to adopt ruler, compasses, protractor, wastes time and energy, and influences efficiency of teaching.
Summary of the invention
The purpose of the utility model is to provide a kind of hyperbolic linear speed that meets the hyperbola standard that can draw fast to draw template.
For reaching above purpose, the technical scheme that the utility model adopted is: this hyperbolic linear speed is drawn template, comprises rectangular flat plate; It is characterized in that: on the center line of rectangular flat plate, be provided with dovetail groove; On the center line of dovetail groove, be provided with the linear through hole, in dovetail groove, be provided with the dovetail slide block, in the central through hole of dovetail slide block, fix chalk sleeve; Chalk sleeve inserts in the linear through hole, is embedded in chalk at chalk sleeve; On the rectangular flat plate of dovetail groove both sides, be provided with the through hole that meets the hyperbola standard; Be provided with telescopic dwang in the both sides of dovetail slide block; Fix the hyp chalk sleeve of picture in the end of telescopic dwang; Draw hyp chalk sleeve insertion and meet in the through hole of hyperbola standard, drawing the embedded pictaresque hyp chalk of hyp chalk sleeve.
The utility model is also implemented through following measure: described telescopic dwang is established two joints, and prosthomere is inserted in the tube chamber of deutomerite, and the seat end of deutomerite is fixed through the sidewall of bearing pin and dovetail slide block; One end of described extension spring and the sidewall of telescopic dwang are fixed, and the sidewall of the other end and dovetail slide block is fixed.
The through hole of described hyperbola standard is symmetrical in the linear through hole.
The beneficial effect of the utility model is: this hyperbolic linear speed is drawn template because with the hyperbola templating, the chalk that will draw straight line through the dovetail slide block again with draw hyp chalk and be connected in the one slip, so the hyperbola of standard that can draw fast and accurately.
Description of drawings
Fig. 1 is the structure schematic top plan view of the utility model.
Among the figure: 1, rectangular flat plate; 2, dovetail groove; 3, linear through hole; 4, dovetail slide block; 5, chalk sleeve; 6, chalk; 7, the through hole that meets the hyperbola standard; 8, telescopic dwang; 9, extension spring; 10, bearing pin; 11, draw hyp chalk sleeve; 12, draw hyp chalk.
The specific embodiment
Make the utility model with reference to Fig. 1.This hyperbolic linear speed is drawn template, comprises rectangular flat plate 1, it is characterized in that: on the center line of rectangular flat plate 1, be provided with dovetail groove 2; On the center line of dovetail groove 2, be provided with linear through hole 3, in dovetail groove 2, be provided with dovetail slide block 4, in the central through hole of dovetail slide block 4, fix chalk sleeve 5; Chalk sleeve 5 inserts in the linear through hole 3; Be embedded in chalk 6 at chalk sleeve 5, when dovetail slide block 4 when dovetail groove 2 slides, chalk 6 can be along linear through hole 3 straight line that draws; On the rectangular flat plate 1 of dovetail groove 2 both sides; Be provided with the through hole 7 that meets the hyperbola standard; Be provided with telescopic dwang 8 in the both sides of dovetail slide block 4, fix in the end of telescopic dwang 8 and draw hyp chalk sleeve 11, draw hyp chalk sleeve 11 insertions and meet in the through hole 7 of hyperbola standard; Drawing hyp chalk sleeve 11 embedded pictaresque hyp chalks 12; Be provided with extension spring 9 in the inboard of telescopic dwang 8, when dovetail slide block 4 slides, when chalk 6 draws straight line along linear through hole 3, draws hyp chalk 12 also along the through hole 7 that meets the hyperbola standard hyperbola that draws along dovetail groove 2.
Improvement as the utility model: described telescopic dwang 8 is established two joints, and prosthomere is inserted in the tube chamber of deutomerite, and the seat end of deutomerite is fixed through the bearing pin 10 and the sidewall of dovetail slide block 4; One end of described extension spring 9 and the sidewall of telescopic dwang 8 are fixed, and the sidewall of the other end and dovetail slide block 4 is fixed.
The through hole 7 of described hyperbola standard is symmetrical in linear through hole 3.
