The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

Example one

As shown in fig. 1-2, the present embodiment provides a variable shape measuring scale, which includes a flexible rule 1 and a plastic strip 2, wherein the front surface of the flexible rule 1 is provided with scales; the length of the plastic strip 2 is the same as that of the flexible ruler 1, and the plastic strip 2 is arranged in parallel with the flexible ruler 1; the plastic strip 2 and the flexible ruler 1 have a bending state and a linear state at the same time, the plastic strip 2 can be bent into a curve state and can restore to the linear state, and the plastic strip 2 is configured to be capable of keeping the bending state or the linear state under the action of no external force; the plastic strip 2 is detachably connected with the flexible ruler 1.

This changeable dipperstick of shape can utilize plasticity strip 2 to carry out moulding to flexible chi 1 as required measuring low-voltage line's trend for changeable dipperstick of shape and low-voltage line laminating, and then can obtain comparatively accurate measuring result, and measurement of efficiency is high. In addition, can buckle into the multistage when accomodating, save space, portable.

Because plasticity strip 2 can dismantle with flexible chi 1 and be connected, can in time change after the performance of plasticity strip 2 is impaired, be favorable to guaranteeing that the measurement accuracy of the changeable dipperstick of shape is in error range.

The fitting manner of the plastic strip 2 and the flexible rule 1 directly affects the fitting speed of the plastic strip and the flexible rule and the use precision after assembly. In this embodiment, optionally, the measuring scale with a variable shape further includes an end cover 12, the flexible scale 1 is provided with a long cylinder 11, the plastic strip 2 is arranged in the long cylinder 11 in a penetrating manner, and the end cover 12 can seal an opening of the long cylinder 11. This setting makes plasticity strip 2 can be in a long section of thick bamboo 11, only need during the installation wear to locate in a long section of thick bamboo 11 and screw up end cover 12 with plasticity strip 2 can, convenient operation, and the installation effectiveness is high. The section of the long tube 11 may be circular, the section of the plastic strip 2 is also circular, and the inner diameter of the section of the long tube 11 is slightly larger than the outer diameter of the section of the plastic strip 2. Optionally, the inner diameter of the section of the long cylinder 11 is 2 mm larger than the outer diameter of the section of the plastic strip 2. This setting can prevent that plasticity strip 2 installation process from taking place the friction with a long section of thick bamboo 11, has improved plasticity strip 2's installation effectiveness, also can not cause great influence to measurement accuracy for measurement accuracy is in the error range that allows.

Further, the end cap 12 is screwed with the opening of the long tube 11. The inner diameter of the end cap 12 is equal to the outer diameter of the opening of the long tube 11. This setting can accomplish the sealed of end cover 12 with a long section of thick bamboo 11 fast, has improved the cooperation efficiency of end cover 12 with a long section of thick bamboo 11, has also improved the installation effectiveness of plasticity strip 2 and flexible chi 1 to a certain extent. In other embodiments, the end cap 12 may also be a plug made of a truncated cone-shaped rubber material, and the end cap 12 may be inserted into the opening of the long tube 11. This setting installation effectiveness is high, and can be waterproof.

Because in the manufacturing process, there is the deviation in every technology, consequently, there is corresponding deviation also in the length of plasticity strip 2 and the length of flexible chi 1 for after the plasticity strip 2 penetrates long section of thick bamboo 11, also can't support tightly with plasticity strip 2 after end cover 12 screws up, lead to plasticity strip 2 to be in the active condition in long section of thick bamboo 11, and then influence measurement accuracy. For this purpose, in this embodiment, further, the end cap 12 includes a tightening assembly, one end of the plastic strip 2 abuts against the tightening assembly, and the other end abuts against the bottom of the long tube 11. In the present embodiment, the tightening unit preferably includes an elastic member 121 and a sliding block 122, the sliding block 122 is disposed in the end cover 12 and can move in the end cover 12 along the center line direction of the end cover 12, the elastic member 121 is disposed between the end cover 12 and the sliding block 122, and one end of the plastic strip 2 abuts one end of the sliding block 122 away from the elastic member 121. The elastic member 121 may be a compression spring, and both ends of the compression spring are welded and fixed to the end cover 12 and the sliding hole 122. This setting makes plasticity strip 2 be in the bobbin base and the sliding block 122 of being long section of thick bamboo 11 and support the state tight all the time after end cover 12 screws up, can guarantee that plasticity strip 2 can insert the bobbin base of long section of thick bamboo 11, and the initiating terminal of flexible chi 1 has plasticity strip 2 promptly, measures the initiating terminal that the homoenergetic started from flexible chi 1 at every turn, has improved measurement accuracy.

Regarding the sliding block 122, in this embodiment, optionally, a groove 1221 is disposed on a side of the sliding block 122 close to the plastic strip 2, and the plastic strip 2 can be clamped in the groove 1221. Further, the groove 1221 is a tapered groove, and the inner diameter of the groove 1221 gradually increases in a direction approaching the malleable strip 2. This set up recess 1221 and can place solid-state lubricating oil for plasticity strip 2 can be in end cover 12 tightening process and the fitting surface frictional force of sliding block 122 reduce, and the toper structure makes the contact between sliding block 122 and plasticity strip 2 be line contact, further reduces the friction between the two, prevents end cover 12 tightening process, and the wrench movement appears in plasticity strip 2, and then leads to measurement accuracy to reduce.

Optionally, a long tube 11 is provided on the back of the flexible rule 1. This setting can be when measuring, pastes tight low-voltage line with the front of flexible rule 1, and then makes measuring result more accurate. Of course, in other embodiments, the long tube 11 may be provided on the side of the flexible rule 1.

In one embodiment, the flexible rule 1 has a plurality of sections, and the flexible rule 1 of each two adjacent sections has different colors. Optionally, the flexible rule 1 has a graduated portion of 2-8 metres in length. Specifically, the length of the flexible ruler 1 is 8 meters, the first meter is white, the second meter is red, the latter is white and red, and the graduation of the flexible ruler 1 is 1 decimeter. This arrangement facilitates rapid counting.

Of course, in other embodiments, the flexible rule 1 may be provided with red graduations at intervals of one meter, or thicker graduations for easy viewing and measurement.

Optionally, the flexible rule 1 is made of PP. The plastic strip 2 is made of iron wire. In this embodiment, the length of the plastic strip 2 may be 8 meters. Or any length of 2-8 meters. This setting is convenient for the selection of materials, and is with low costs, and PP material wearability is good, can improve the life of this embodiment.

Example two

The present embodiment provides a measuring ruler with a variable shape, which has a structure substantially the same as that of the first embodiment, except that the plastic strip 2 is a copper wire.
