Abstract
The utility model provides a four-line three-part scriber which comprises a supporting rod. An upper groove and a lower groove are respectively arranged on lateral surfaces of the supporting rod, and the upper groove and the lower groove are oppositely arranged and communicated through an inner cavity of the supporting rod. At least four locators which are used for locating chalk are connected on the supporting rod, and the locators are all connected with the supporting rod in a sliding mode through the upper groove and the lower groove. By adopting the locators to fix the chalk respectively, a teacher is enabled to draw a plurality of parallel straight lines when drawing lines. Moreover, the four-line three-part scriber is capable of assisting the teacher to draw the lines quickly, improves the precision of line drawing, simplifies operation, improves efficiency of classroom teaching, and reduces burdens of the teacher.
Description
Technical field
The utility model relates to a kind of scriber, is specially a kind of four lines, three lattice scribers, belongs to the teaching aid technical field.
Background technology
At present in the process of classroom instruction, teachers are general or adopt the mode of writing at blackboard to impart knowledge to students, the chalk instrument that then is absolutely necessary.For English teaching, because strict format specification is arranged when writing letter, both four lines, three lattice, so teacher usually need to be after drawing first the line lattice on the blackboard, just can write, and owing to lack special instrument, teacher often relatively requires great effort in the process of setting-out, not only time-consuming, and the spacing of line lattice etc. can not reach the demand of standard, and this tends to make troubles to teaching, has affected the quality of instruction that improves the classroom.
The utility model content
For above-mentioned deficiency of the prior art, main purpose of the present utility model is to solve now the at present larger problem of setting-out difficulty in process of English teaching, and a kind of four lines, the three lattice scribers that can assist teacher's quick line drawing are provided.
The technical solution of the utility model: four lines, three lattice scribers, it is characterized in that, comprise support bar, be respectively equipped with upper groove and low groove in the side of support bar, described upper groove and low groove are oppositely arranged and pass through the inner chamber connection of support bar; Be connected with at least four at described support bar and be used for the fixedly locator of chalk, described locator all is slidingly connected by upper groove and low groove and support bar.By adopting respectively fixing chalk of locator, and the chalk on each locator can keep being parallel to each other after being fixed in the utility model, thereby so that can draw simultaneously many parallel straight lines during setting-out.
Further technical scheme, described locator are to be made of a draw-in groove and the bolt that is fixed on this draw-in groove, and locator passes behind the upper groove of support bar and the low groove nut locking by correspondence again.Locator in the utility model mode with bolts when installing and fixing so not only is conducive to regulate the lateral separation between each locator, and the time that the location is installed has been saved in also fast and easy locking.
Further again, the opening diameter of draw-in groove is greater than the diameter of draw-in groove bottom surface on the described locator.By being similar to the draw-in groove shape of V font, more be conducive to the chalk chucking is prevented that it from use coming off, strengthened the stability of scriber.
With respect to prior art, the utlity model has following beneficial effect:
1, can assist teacher's quick line drawing: can directly effectively realize the setting-out location by scriber of the present utility model, and can finish simultaneously many parallel lines, be conducive to save time.
2, improved the setting-out precision: owing to all can pre-set the location of chalk on the scriber, therefore the spacing between every line can both keep relatively even, like this so that the whole structure of line lattice is better.
3, simplify operation, improved the efficient of classroom instruction, alleviated teacher's burden.
Description of drawings
Fig. 1 is the structural representation of the utility model four lines three lattice scribers.
Among the figure, 1-support bar, 21-upper groove, 22-low groove, 3-locator, 4-chalk.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of four lines, three lattice scribers comprise support bar 1, and described support bar 1 adopts the tubular body structure of hollow, can be pipe, also can be square tube or other tubing.Be respectively equipped with upper groove 21 and low groove 22 in the side of support bar 1, the width of upper groove 21 and low groove 22 basic identical and separately width be not more than 1/3 of support bar 1 circumferential length, described upper groove 21 and low groove 22 are oppositely arranged and the inner chamber by support bar 1 is communicated with.Be connected with at least four at described support bar 1 and be used for the fixedly locator 3 of chalk, described locator 3 is to be made of a draw-in groove and the bolt that is fixed on this draw-in groove, and the opening diameter of draw-in groove is greater than the diameter of draw-in groove bottom surface on the locator 3.Locator 3 passes behind the upper groove 21 of support bar 1 and the low groove 22 the nut locking by correspondence again.Described locator 3 all is slidingly connected with support bar 1 by upper groove 21 and low groove 22.
During use, get first four chalks, snap onto respectively in the draw-in groove of each locator, because the draw-in groove of locator is the V character form structure, therefore can be easily with its chucking.After having blocked chalk, each locator of transverse shifting makes its spacing each other keep basic identical, and the width of concrete spacing can be selected voluntarily by teacher, and then the locking of the nut on each locator is got final product.Teacher holds support bar, and a horizontal setting-out just can produce four parallel straight lines on blackboard.
Need to prove, above embodiment is only in order to technical solutions of the utility model to be described but not the restriction technologies scheme, although the applicant has done detailed description with reference to preferred embodiment to the utility model, those of ordinary skill in the art is to be understood that, the modification that those carry out technical solutions of the utility model or be equal to replacement, aim and the scope that can not break away from the technical program all should be encompassed in the middle of the utility model claim scope.
