Abstract
The utility model provides an English three-line drawing tool capable of using chalk stubs, and belongs to the technical field of line drawing tools. A through sliding groove is formed in one side of a straight plate in the axial direction, a rotating wheel is arranged on a rotating wheel frame, a sliding block is connected with the sliding groove in the straight plate in a sliding mode, each chalk stub clamping device comprises a handle, a screw rod, a sleeve pipe and rubber bars in a triangular shape, the sleeve pipes are fixedly connected with the straight plate, one end of each screw rod is in threaded connection with the corresponding sleeve pipe, the other end of the corresponding screw rod is fixedly provided with the corresponding handle, and the rubber bars in the triangular shape are fixed to the inner portion of one side of a chalk stub outlet of the corresponding sleeve pipe. According to the English three-line drawing tool capable of using the chalk stubs, the three rubber bars in the triangular shape are fixed in the inner portion of one side of the chalk stub outlet of the corresponding sleeve pipe, the rubber bars in the triangular shape are elastic, chalk stubs are clamped stably to draw lines by relying on the elasticity and the deformation of the rubber bars in the triangular shape, and thus short chalk stubs can be used for drawing the lines. The height of the lines drawn on a blackboard can be regulated by using the upper edge or the lower edge of the blackboard through the rotating wheel on the straight plate.
Description
Technical field
The utility model relates to a kind of English three lattice setting-out apparatus that utilize chalk end, belongs to setting-out apparatus technical field.
Background technology
Existing English three lattice setting-out apparatus are all to use longer chalk setting-out conventionally, and chalk is too short to be substantially just done for.Above-mentioned setting-out apparatus does not all limit the function of oneself height conventionally, and the line drawing on blackboard, although four lines are parallel to each other, is not level.
Summary of the invention
The purpose of this utility model is the problem existing in order to solve above-mentioned prior art, and existing English three lattice setting-out apparatus are all to use longer chalk setting-out conventionally, and chalk is too short to be substantially just done for.Above-mentioned setting-out apparatus does not all limit the function of oneself height conventionally, and the line drawing on blackboard, although four lines are parallel to each other, is not level.And then provide a kind of English three lattice setting-out apparatus that utilize chalk end.
The purpose of this utility model is achieved through the following technical solutions:
A kind of English three lattice setting-out apparatus that utilize chalk end, comprise: runner, straight plate, four chalk end fastening and loading devices, screw piece, slide block and rotary wheel frame, a side shaft on described straight plate to be provided with penetrating chute, one side and the rotary wheel frame of slide block are connected as a single entity, runner is arranged on rotary wheel frame, slide block is slidably connected with the chute on straight plate, the opposite side of slide block is provided with and screws piece, screwing piece is threaded with slide block, opposite side on straight plate is evenly equipped with four chalk end fastening and loading devices, described each chalk end fastening and loading device comprises handle, screw rod, sleeve pipe and triangle rubber strip, sleeve pipe is fixedly connected with straight plate, one end of screw rod is connected with casing threads, the other end of screw rod is fixed with handle, the chalk end of sleeve pipe exports and in a side, is fixed with triangle rubber strip.The chalk end of described sleeve pipe exports in a side and is fixed with three triangle rubber strips, and three triangle rubber strips are equilateral triangle and distribute.
The utility model is fixed with three triangle rubber strips in the chalk end of sleeve pipe exports a side, triangle rubber strip is resilient, elasticity and deformation grip chalk end by self carry out setting-out stably, therefore can use shorter chalk end setting-out, chalk itself is that a large diameter of diameter is little, the diameter of chalk end is of all kinds, and such chalk end the utility model can use.Runner on straight plate can utilize the upper edge of blackboard or lower edge to carry out the height of standard setting-out on blackboard.If blackboard is the very thin upper and lower edge that do not have, desk can be placed on below blackboard and do platform, allow runner walk on desk, setting-out can be up to the standard.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model can utilize the English three lattice setting-out apparatus of chalk end;
Fig. 2 is the generalized section that the utility model can utilize the English three lattice setting-out apparatus of chalk end;
Fig. 3 is the chalk end outlet of sleeve pipe and the position relationship schematic diagram of three triangle rubber strips.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail: the present embodiment is implemented under take technical solutions of the utility model as prerequisite, has provided detailed embodiment, but protection domain of the present utility model is not limited to following embodiment.
As shown in FIG. 1 to 3, a kind of English three lattice setting-out apparatus that utilize chalk end that the present embodiment is related, comprise: runner 1, straight plate 2, four chalk end fastening and loading devices, screw piece 7, slide block 8 and rotary wheel frame 9, a side shaft on described straight plate 2 to be provided with penetrating chute 6, one side and the rotary wheel frame 9 of slide block 8 are connected as a single entity, runner 1 is arranged on rotary wheel frame 9, slide block 8 is slidably connected with the chute 6 on straight plate 2, the opposite side of slide block 8 is provided with and screws piece 7, screwing piece 7 is threaded with slide block 8, opposite side on straight plate 2 is evenly equipped with four chalk end fastening and loading devices, described each chalk end fastening and loading device comprises handle 3, screw rod 4, sleeve pipe 5 and triangle rubber strip 10, sleeve pipe 5 is fixedly connected with straight plate 2, one end of screw rod 4 is threaded with sleeve pipe 5, the other end of screw rod 4 is fixed with handle 3, the chalk end of sleeve pipe 5 exports and in a side, is fixed with triangle rubber strip 10.
The chalk end of described sleeve pipe 5 exports and in a side, is fixed with 10, three triangle rubber strips 10 of three triangle rubber strips and is equilateral triangle and distributes.
The above; it is only the preferably specific embodiment of the utility model; these specific embodiment are all the different implementations based under the utility model general idea; and protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
