Abstract
The invention discloses a portable telescopic compass, which comprises a portable box body, wherein a box body connecting part is arranged in the middle of the portable box body, cavities are arranged on two sides of the portable box body, the compass is arranged in the cavity on one side of the portable box body through a pivot shaft, the compass comprises a first compass foot and a second compass foot, and the first compass foot and the second compass foot can slide relatively. The portable telescopic compasses are small in size and convenient to carry, the compasses can stretch out and draw back due to relative sliding of the compasses feet, drawing requirements of circles with different diameters are met, and meanwhile, the portable telescopic compasses further comprise a tape measure and can be used for measuring data.
Description
Technical Field
The invention relates to the field of drawing tools, in particular to a portable telescopic compass.
Background
The compasses are often used when people need to draw, however, the existing compasses are large in size, difficult to carry about, and can not be used by required personnel at any time and any place.
Therefore, the invention aims to provide a portable telescopic compass which is small in size and convenient to carry and can meet different drawing requirements.
Disclosure of Invention
The invention aims to solve the problems that the existing compasses are large in size, inconvenient to carry and incapable of drawing at any time and any place, and provides a small and portable compasses box.
In order to achieve the purpose, the invention provides the following technical scheme:
the utility model provides a portable scalable compasses, includes portable box body, the middle part of portable box body is provided with box body connecting portion, and both sides are the cavity, and the compasses sets up through the pivotal axis in the cavity of one side of portable box body, the compasses include first compasses foot and second compasses foot, but relative slip between first compasses foot and second compasses foot.
Preferably, first compasses foot spout has been seted up in the first compasses foot, first compasses foot spout one side is provided with first nut, second compasses foot spread groove has been seted up on the second compasses foot, the welding of second compasses foot spread groove one side has the second nut, first compasses foot spout with second compasses foot spread groove is connected through the threaded rod that passes the two.
Preferably, a measuring tape is arranged in the cavity on the other side of the portable box body and is connected with the portable box body through a rotating shaft.
Preferably, the two side walls of the portable box body along the length direction are provided with openable box covers.
The invention has the beneficial effects that:
the portable telescopic compasses adopt the portable box body, so that the compasses can be conveniently carried about;
the compasses are more convenient and faster to take and use by connecting the pivot shaft with the compasses;
the two compasses feet of the compasses can slide relatively, so that the drawing requirements of circles with different diameters can be met;
meanwhile, the compasses also comprise a measuring tape which can be used for measuring data.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Unless otherwise indicated, all references to up, down, left, right, front, back, inner and outer directions herein are to be interpreted as referring to up, down, left, right, front, back, inner and outer directions in the drawings to which the invention is directed.
The invention provides a portable telescopic compass as shown in figure 1, which comprises a portable box body 1, wherein a box body connecting part 12 is arranged in the middle of the portable box body 1, cavities are arranged at two sides of the portable box body 1, a compass 13 is arranged in the cavity at one side of the portable box body 1 through a pivot shaft 2, the compass 13 comprises a first compass foot 3 and a second compass foot 5, and the first compass foot 3 and the second compass foot 5 can slide relatively.
Specifically, as shown in fig. 4 and 5, first compasses foot spout 4 has been seted up in the first compasses foot 3, first compasses foot spout 4 one side is provided with first nut 10, second compasses foot spread groove 6 has been seted up on the second compasses foot 5, the welding of 6 one side of second compasses foot spread groove has second nut 11, first compasses foot spout 4 with second compasses foot spread groove 6 is connected through the threaded rod 7 that passes the two.
Specifically, a measuring tape 9 is arranged in a cavity on the other side of the portable box body 1, and the measuring tape 9 is connected with the portable box body 1 through a rotating shaft 8.
Specifically, two side walls of the portable box body 1 along the length direction thereof are provided with openable box covers 14.
The user is when needs are drawn, can take out this portable scalable compasses at any time, the diameter of the circle as required, adjust the length of the tie point distance pivotal axis between two compasses feet, during the regulation, make the threaded rod drive second compasses foot spread groove and slide from top to bottom in first compasses foot spout, the user confirms good own required length after, through first nut, it is fixed to make between the two, begin to draw, after the drawing is accomplished, place it back in portable box body 1 can, if there is the measurement that carries out data, the tape measure in the optional opposite side cavity.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
