Abstract
The utility model discloses a universal surveyor's rod, relating to the field of writing or drawing instruments. The prior art has the disadvantages that a vernier caliper is lacked, the installation of a pen core is trouble, a set square can not be movably used. The utility model is characterized in that the bottom of a protractor is horizontally connected with one end of a ruler, and the edge of the ruler forms a straight line with the center line of the protractor. A positioner is arranged on the center point of the bottom edge of the protractor, and the lower end is provided with a needle. A spring is positioned in a hollow cavity arranged below the center point of the bottom edge of the protractor, and the needle penetrates through the spring and the protractor. The bottom of a sliding ruler is provided with two chutes, and the chute pitch is equal with the width of the ruler. When the ruler is positioned in the chute, the sliding ruler can be moved on the ruler, and the sliding ruler is fixed on the ruler by a stop nail.
Description
This use novel relating to, write or the drawing instrument technical field.
In the prior art, the drawing instrument of various combinations is more, is 92201801 patents of one as collection ruler, protractor; 94246590 patents that integrate ruler, protractor, compasses all have characteristic separately, still, on function, lack slide measure; From using, exist the pen core trouble is installed, and set square such as can not dynamically use at shortcoming.Can not satisfy the widespread demand in people's practical application.
The novel purpose of this use is: overcome the deficiency of above-mentioned prior art, desire designs a kind of ruler, protractor, compasses, slide measure of integrating, and can satisfy the Universal surveyor's rod of the widespread demand in people's practical application.
This use is novel to be to design like this: protractor (1) bottom is connected with ruler (3) one end levels, the center line of the edge of ruler (3) and protractor (1) 90 degree draws a straight line, on the central point of protractor (1) base locator (2) is arranged, there is pin (9) lower end of locator (2), spring (11) places in the cavity under the central point of protractor (1) base, spring (11) is passed in pin (9) lower end, protractor (1), two chutes (5) are arranged at the bottom of slip ruler (4), (8), two chutes (5), (8) slot pitch equates with the width of ruler (3), ruler (3) places chute (5), (8) in, non-magnetic shim (6) passes slip ruler (4), and contacts with the chi face of ruler (3).Ruler (3) other end has joint (7), an end of slip ruler (4) fluted (10), and joint (7) is loose fit with the groove (10) of slip ruler (4)
The novel advantage of this use is: simple in structure, cost of manufacture is cheap, owing to integrate ruler, protractor, compasses, slide measure, can dynamically use set square, compasses, and satisfied the widespread demand in people's practical application.It is the comparatively ideal drafting instrument of student, engineers and technicians.
Fig. 1 is the novel front view of this use;
Fig. 2 is the novel locator structure figure of this use;
The slip ruler structure chart that this use of Fig. 3 is novel.
This use is novel to be to implement like this: protractor (1) bottom is connected with ruler (3) one end levels, the center line of the edge of ruler (3) and protractor (1) 90 degree draws a straight line, on the central point of protractor (1) base locator (2) is arranged, there is pin (9) lower end of locator (2), spring (11) places in the cavity under the central point of protractor (1) base, spring (11), protractor (1) are passed in pin (9) lower end, two chutes (5), (8) are arranged at the bottom of slip ruler (4), and the slot pitch of two chutes (5), (8) equates with the width of ruler (3).Ruler (3) places in chute (5), (8), and can make slip ruler (4) go up move left and right at ruler (3).Non-magnetic shim (6) passes the screwed hole at slip ruler (4) middle part, and its screw thread (12) cooperates with the screwed hole at the middle part of slip ruler (4) and the bottom of non-magnetic shim (6) is contacted with the chi face of ruler (3).Screwing non-magnetic shim (6) can be fixed on slip ruler (4) on the optional position of ruler (3).Ruler (3) other end has joint (7), an end of slip ruler (4) fluted (10), and joint (7) is loose fit with the groove (10) of slip ruler (4).Can make ruler (3) and slip ruler (4) connect into the ruler of a lengthening like this.If slip ruler (4) is fixed on the optional position of ruler (3) through non-magnetic shim (6), pin locator (2), lean against ruler (3) with nib and can draw circle with the place, right angle of slip ruler (4).
