Description

Technical Field

[0001] The utility model relates to a measuring tool, in particular to a measuring tool for quickly measuring the length of a roll paper package. Background Art

[0002] In the field of conventional household paper, paper rolls are generally measured once every 25 minutes or so. A steel tape measure is used to measure the length of the packaging paper roll. During the measurement operation, the steps of finding the tape measure, straightening the tape measure, measuring, curling the tape measure, and putting the tape measure back are time-consuming. When different people are measuring, errors will be caused by different operations of each person. In addition, because the roll is an arc, the accuracy of the steel tape measure is not high.

[0003] In the existing length measuring tool, the rotation of the threaded rod drives the slider to move horizontally, and the movement of the slider drives the clamping plate to move, so that the gap between the clamping plate and the baffle is reduced, so that the part can be fixed, but the measuring efficiency of the measuring tool is low.

[0021] Figure 4 yes Figure 3 A partial enlarged view of . DETAILED DESCRIPTION

[0022] The utility model will be further described below in conjunction with the accompanying drawings.

[0023] like Figures 1 to 4As shown, the measuring tool of the utility model is tiltedly arranged on a platform 1, which can be an ordinary desktop. The platform 1 has an opening running through it from top to bottom, and the measuring tool is installed in the opening. The measuring tool includes a rear plate 2, a side plate 3, a movable pressing plate 4 and a bottom plate 5, wherein the bottom plate 5 is tiltedly installed in the opening of the platform 1, and the tilt angle is between 1° and 10°. The rear plate 2 and the side plate 3 are installed on the bottom plate 5, wherein the side plate 3 is fixed to one side of the rear plate 2, and the side plate 3 is located at the lower part of the tilted bottom plate. One end of the movable pressing plate 4 is slidably installed on the rear plate 2, and the bottom of the other end is slidably connected to the slot 11 on the platform 1 through a connecting structure. The side plate 3, the rear plate 2 and the movable pressing plate 4 form a three-enclosed structure, and the paper roll to be measured is put in from the notch of the three-enclosed structure, and the paper roll to be measured is made to lean against the side of the side plate 3 by gravity along the tilt of the bottom plate 5, without manual correction and pushing the paper roll to be straightened.

[0024] like Figure 1 and Figure 2 As shown, the platform 1 is provided with parallel slots 11, and the movable bottom plate 4 is slidably connected in the slots 11. Figure 3 and Figure 4 As shown, the connection structure includes a connection block 42 at the bottom of the movable pressing plate 4, the bottom of the connection block 42 is connected to the limit block 44 through a spring 43, and a roller 45 is provided at the bottom of the limit block 44, which drives the movable pressing plate 4 to slide in the slot 11 to ensure the stable sliding of the movable pressing plate 4, and an iron block 47 is provided on the side of the limit block 44 facing the slot 11, and a magnetic block 46 is provided on the inner wall of the slot 11 corresponding to the iron block 47, and the magnetic attraction structure composed of the magnetic block 46 and the iron block 47 ensures that the movable pressing plate 4 will not slide when it is in the initial position, so as to limit the movable pressing plate 4. When the movable pressing plate 4 is at the high position of the inclined bottom plate, the spring release length is greater than the spring release length when the movable pressing plate 4 is at the low position of the inclined bottom plate.

[0025] like Figure 2 As shown, both sides of the top of the rear plate 2 are provided with protrusions 21, and a positioning rod 8 is connected between the protrusions 21 on both sides. The positioning rod 8 is provided with a length measuring scale line 6, and a movable pressing plate 4 is provided with a lug 41 on the side close to the rear plate 2. The movable pressing plate 4 is sleeved on the outside of the positioning rod 8 through the lug 41 and can slide along the positioning rod 8. The side of the rear plate 2 close to the side plate 3 is provided with a height measuring scale line 7. After the measured paper roll is placed on the bottom plate 5, the movable pressing plate 4 is pushed closer to the side plate 3 on the outside of the movable pressing plate 4, and finally pressed against the measured paper roll. At this time, the scale data on the length measuring scale line 6 and the height measuring scale line 7 can be read, so as to obtain the length and height of the measured paper roll, simplifying the measurement process and improving the measurement efficiency.

[0026] The positioning rod 8 of the utility model is parallel to the rear plate 2 and the bottom plate 5, that is, the positioning rod 8 and the rear plate 2 are also inclined 1° to 10° relative to the platform 1, the side plate 3 is parallel to the movable pressure plate 4, and the movable pressure plate 4 and the bottom plate 5 are perpendicular. Because the movable pressure plate 4 will slide to the lower side due to the factor of gravity, when the movable pressure plate 4 is at the highest point, the spring 43 will expand outward, causing the roller 45 to abut against the lower bottom wall of the slot 11, and the magnetic attraction structure between the limit block 44 and the inner wall of the slot 11, thereby controlling the limit block 44 and the movable pressure plate 4 not to slide to the side of the side plate 3 due to gravity without human force. When it is necessary to measure the paper roll to be measured, the movable pressure plate 4 is pushed manually to release the friction between the magnetic block 46 and the iron block 47, and the roller 45 and the lower bottom wall of the slot 11 to complete the measurement.

[0027] The working principle of the utility model is:

[0028] The paper roll to be measured is placed into the gap of the three-surrounding structure, and gravity is used to make the paper roll to be measured lean against the side plate 3 along the inclination of the bottom plate 5; the movable pressing plate 4 is pushed to release the friction between the magnetic block 46 and the iron block 47, and the roller 45 and the bottom wall of the slot 11, so that the movable pressing plate 4 moves toward the side plate 3 and presses against the paper roll to be measured, and the length and height of the paper roll to be measured are read out through the length measuring scale line and the height measuring scale line respectively.
