Detailed Description
The invention is further described below with reference to the accompanying drawings.
Example 1
The simple carpenter's ruler comprises a main ruler body 1, a ruler head 2 and a locking knob 3, wherein the ruler head 2 is in a cuboid shape, a through groove 21 for the main ruler body 1 to be vertically inserted is formed in the side wall of the ruler head 2, a circular through hole 22 communicated with the through groove 21 is formed in the end face of the bottom end of the ruler head 2, and internal threads are arranged in the through hole 22; one end of the main ruler body 1 is vertically inserted into a through groove 21 on the side wall of the ruler head 2 and can slide left and right in the through groove 21; the locking knob 3 is provided with an external thread matched with an internal thread on the through hole 22, the locking knob 3 is in threaded connection with the through hole 22, the top end of the locking knob 3 is penetrated out of the through hole 22 and is abutted against the lower end of the main ruler body 1 by rotating, so that the main ruler body 1 is firmly clamped on the ruler head 2, in particular to the through groove 21 on the ruler head 2, the axial section of the locking knob 3 is T-shaped, and the locking knob 3 is conveniently and easily rotated by hands. Through adjusting the locking knob 3, the main ruler body 1 can slide left and right in the through groove 21, when a certain specific length is needed to be used for measurement, the main ruler body 1 can slide left, the length of the main ruler body 1 on the right side of the ruler head 2 is adjusted to be equal to the certain specific length which is used frequently, then the locking knob 3 is adjusted, so that the main ruler body 1 is clamped on the ruler head 2, when the specific length is needed to be used repeatedly for measurement later, the main ruler body 1 on the right side of the ruler head 2 can be directly used for comparison as a standard, the scale on the main ruler body 1 is not needed to be watched, the error measurement is not needed, and the ruler is simple, convenient and high in efficiency.
In this embodiment, in order to make locking knob 3 can be better with main scale body 1 card firmly, be equipped with the fixture block 4 that is the T style of calligraphy between locking knob 3 and the main scale body 1, fixture block 4 include horizontal card strip 41 and with card strip 41 vertically jack-up post 42, card strip 41 with main scale body 1 is parallel and laminating main scale body 1 lower extreme, card strip 41 is the cuboid, the one end of jack-up post 42 is fixed the intermediate position of card strip 41 lower extreme face, its other end is embedded into in the through-hole 22 and with the top of locking knob 3 is inconsistent. Because fixture block 4 is the T style of calligraphy, its top is bigger with the area of contact of main scale body 1, and the laminating is inseparabler, when locking knob 3 transfers tightly, fixture block 4 can be with the more firm of main scale body 1 card, in addition, set up behind the fixture block 4, can avoid locking knob 3 top direct conflict on main scale body 1, prevent that locking knob 3 from causing the harm to main scale body 1.
As shown in fig. 4 and 5, in this embodiment, the top post 42 has a rectangular or triangular prism shape, and when it is vertically inserted into the through hole 22, the ribs on the side wall of the top post 42 are all in contact with the inner wall of the through hole 22. By this arrangement, the material consumed for manufacturing the post 42 can be saved, and the post 42 can be prevented from shaking in the through hole 22.
As shown in fig. 1 and 2, in this embodiment, the lower end of the main blade 1 is sequentially provided with a plurality of auxiliary blades 5 with unequal lengths from top to bottom, the lengths of the plurality of auxiliary blades 5 decrease from top to bottom, one ends of the plurality of auxiliary blades 5 are vertically inserted into the through groove 21 and can slide left and right in the through groove 21, the top end of the clamping block 4 is abutted against the lower end of the auxiliary blade 5 at the lowest part, and under the abutting pressure of the clamping block 4, the auxiliary blades 5 and the main blade 1 are tightly attached to each other as a whole and fixed on the blade 2. Similarly, after the locking knob 3 is loosened, the length of each auxiliary ruler body 5 on the right side of the ruler head 2 can be adjusted, and after the locking knob 3 is tightened after the adjustment, a plurality of specific lengths can be measured at one time by the aid of each auxiliary ruler body 5, so that the working efficiency is greatly improved; in addition, after the locking knob 3 is tightly adjusted, the auxiliary ruler body 5 and the main ruler body 1 are tightly attached to each other into a whole, so that the firmness of the ruler is greatly improved, and the ruler is firmer and durable.
Referring further to fig. 1 and 2, in this embodiment, a plurality of circular holes 11 with different diameters are formed on the blade surface of the main blade 1. By the arrangement, circular marks with corresponding diameters can be conveniently made on the measured object through the circular holes 11 on the main ruler body 1.
In this embodiment, the thickness of the main blade 1 is equal to the thickness of the auxiliary blade 5 and corresponds to the width of the through slot 21. The setting like this for the wall of main blade 1 and assisting blade 5 all laminates mutually with logical inslot 21 inner wall, can prevent that main blade 1 and assisting blade 5 from rocking in logical inslot 21, can make the ruler more firm.
In this embodiment, the upper and lower sides of the front surfaces of the main and auxiliary scales 1 and 5 are marked with scales, and the scale division values of the scales on the two sides are 1 millimeter and 1/10 inch respectively, the end of the main scale 1 away from the scale head 2 is a zero scale end, and the end of the auxiliary scale 5 away from the scale head 1 is a zero scale end. By the arrangement, unit conversion can be avoided to a certain extent when the measured object is measured, and the working efficiency is improved.
Example 2
The present embodiment is substantially the same as embodiment 1, except that as a further improvement of the present invention, referring to fig. 6, the top post 42 is cylindrical, and the diameter of the end portion of the top post is equal to the inside diameter of the through hole 22, so that when the cylindrical top post 42 is embedded into the through hole 22, the side wall of the top post 42 can be tightly attached to the inner wall of the through hole 22, so that shaking is not easy to occur, and the stability of the simple ruler for woodworker can be further increased.
In addition, a soft magnetic layer is attached to the side wall of the lower side of the main ruler body 1 and the side walls of the upper side and the lower side of each auxiliary ruler body 5, so that the soft magnetic layers are arranged, and the main ruler body 1 and the adjacent auxiliary ruler bodies 5 can be spliced into a whole more easily.
The back surfaces of the main ruler body 1 and the auxiliary ruler bodies 5 are respectively provided with a rubber layer with the same layer thickness, so that the main ruler body can be better attached to the surface of a measured object when the measured object is measured, and the measurement is more accurate.
The above embodiments are only for illustrating the present invention, not for limiting the present invention, and various changes and modifications may be made by one of ordinary skill in the relevant art without departing from the spirit and scope of the present invention, and therefore, all equivalent technical solutions are also within the scope of the present invention, and the scope of the present invention is defined by the claims.
