Detailed ways

The present application will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

As shown in Figures 1-4, the embodiment of the present application provides a measuring assembly of a measuring ruler, which is used to measure the size of an object, the object can be a regular object or an irregular object, and the size can be length, circumference Regular size such as length and radius or irregular size. The measuring assembly may include a roller 10 , a transmission part, a rotating part 11 and a signal collector 12 . The roller 10 is used for rolling along the tested part of the tested object, for example, rolled along the edge of the tested object, so as to measure the length of the edge of the tested object. The roller 10 generally adopts a circular roller, which can be connected to the rotating part 11 through a transmission part. Type transmission part or gear type transmission part or other structures. Considering that the inner space of the measuring ruler is relatively small, it is preferable that the transmission part is a gear type transmission part.

The rotating part 11 is rotatably connected with the signal collector 12 , that is, the signal collector 12 does not move, and the rotating part 11 can rotate relative to the signal collector 12 . There is a grating 110 on the rotating part 11 , and the signal collector 12 is arranged opposite to the grating 110 to collect the rotation distance of the grating 110 . Generally, multiple grid pieces 110 can be provided, and each grid piece 110 can be provided at any feasible position of the rotating part 11 , such as the middle of the rotating part 11 . In order to reduce the size of the rotating part, each grid piece 110 can be arranged at the edge position of the rotating part 11. In addition, the rotating part 11 can also be set as a circular rotating part, and each grid piece 110 can be arranged along the circular rotating part. Evenly arranged in the outer peripheral direction to form a ring structure. Each grating 110 can be further configured as a rectangular grating, so as to simplify the structure of the measuring assembly and facilitate the calculation of the size of the object to be measured.

The structure of the signal collector 12 can refer to the prior art, for example, the signal collector 12 can use at least one group of infrared pair tubes or at least one group of laser pair tubes to transmit and receive signals, which can specifically include a signal transmitting part and a signal The receiving part, the two parts can be respectively disposed on opposite sides of the grid sheet 110 . When the rotating part 11 rotates, the grating 110 will alternately block the light emitted by the infrared tube or the laser tube, so that the signal collector 12 alternately receives high-level signals and low-level signals during this process, and then outputs such as Figure 5 shows a series of square waves.

The square wave obtained by the above-mentioned signal collector 12 can be processed by the processor of the measuring ruler, for example, the required size value can be obtained through conversion by means of chip counting. It should be noted that, the specific working principle of the above-mentioned signal collector 12 can refer to the Chinese patent application with the application number 201620180343.5, which will not be repeated here.

When measuring the size of an object using a measuring ruler including the above-mentioned measuring components, the measuring ruler can be manually driven to move along the part to be measured of the object, so that the roller 10 rolls along the track of the part to be measured, and the rolling wheel 10 will drive The rotating part 11 rotates, so that the signal collector 12 can collect the rotating distance of the rotating part 11, and then obtain the size of the part to be measured. Obviously, after adopting this kind of measuring assembly, it is only necessary to drive the roller 10 to move along the position to be measured to realize the size measurement of the object, and it is not necessary to calculate the size of the object to be measured after segmental measurement. Therefore, the measuring assembly can improve the size of the object. dimensional measurement efficiency.

In addition to the above-mentioned technical effects, the measurement component provided by the embodiment of the present application also has the following advantages:

1. The measuring component is not limited by the shape of the object to be measured and whether the size to be measured is regular, so the measuring ruler using the measuring component has stronger versatility.

2. When performing measurement operations, the measuring ruler using the above-mentioned measuring components can be held with one hand, so that the application scenarios of the measuring ruler are not limited. For example, it can be applied to high-altitude operations, making it more convenient to measure the size of objects.

In order to improve the structural compactness of the measuring assembly and simplify the conversion form of the size value of the object to be measured, the rotating surface of the roller 10 and the rotating surface of the rotating part 11 can be made parallel or coplanar. When the rotating surface of the roller 10 and the rotating surface of the rotating part 11 are parallel to each other, the distance between them can also be controlled within a relatively small range, so as to enhance the aforementioned technical effect. In a specific embodiment, the end surface on one side of the roller 10 may be coplanar with the end surface on the same side of the rotating part 11 .

In one embodiment, the transmission part may include a first transmission gear 13 and a second transmission gear 14, the first transmission gear 13 is coaxially fixed with the rotating shaft of the roller 10, and the second transmission gear 14 is coaxial with the rotating shaft of the rotating part 11 Fixed, the first transmission gear 13 is in transmission connection with the second transmission gear 14 . This transmission mode has the advantages of simple structure, high transmission efficiency and high transmission precision. It can be understood that the first transmission gear 13 and the second transmission gear 14 can be directly meshed, but this way will result in relatively large sizes of both. Therefore, the transmission part can also include a third transmission gear 15, the third transmission gear 15 is located between the first transmission gear 13 and the second transmission gear 14, and the first transmission gear 13 communicates with the second transmission gear 15 through the third transmission gear 15. Gear 14 transmission connection. After such setting, the sizes of the first transmission gear 13 and the second transmission gear 14 can be appropriately reduced.

Further, the outer diameter of the above-mentioned first transmission gear 13 and the outer diameter of the second transmission gear 14 are smaller than the outer diameter of the third transmission gear 15, thereby reducing the first transmission gear 13 and the second transmission gear 14 to a greater extent. and the size of the third transmission gear 15, while facilitating the arrangement of the measuring assembly in the entire measuring ruler.

The shaft axis of the above-mentioned rotating part 11 can be located in the plane formed by the axis of the first transmission gear 13 and the axis of the third transmission gear 15, but under this structure, the distance between the rotating part 11 and the roller 10 needs to be compared large to prevent interference between the two. In view of this, in order to reduce the distance between the rotating part 11 and the roller 10, the following structure can be adopted: the axis of the rotating shaft of the rotating part 11 is located on the plane formed by the axis of the first transmission gear 13 and the axis of the third transmission gear 15 outside. When the latter arrangement is adopted, the rotating part 11 and the roller 10 are relatively staggered, so that the distance between the two can be appropriately reduced, and interference between the two will not easily occur.

For the specific structure of the signal collector 12, the preferred embodiment of the present application is as follows: the signal collector 12 includes a first collection board 120, a second collection board 121 and a connection board 122, and the first collection board 120, the connection board 122 and the second collection board 120 The collecting plates 121 are connected in sequence to form a U-shaped structure, and the grid piece 110 of the rotating part 11 is located between the first collecting plate 120 and the second collecting plate 121 . This setting method can more conveniently set various components of the signal collector 12 , such as the aforementioned signal transmitting part and signal receiving part, and can also improve the working reliability of the signal collector 12 .

Based on the above structure, an embodiment of the present application further provides a measuring ruler. The measuring ruler may include a housing and a measuring component installed inside the housing. The measuring component is the measuring component described in any one of the above-mentioned embodiments.

Preferably, the above-mentioned measuring ruler may also include a processor and a data transmitter disposed inside the housing, the processor is electrically connected to the signal collector 12, to process the data collected by the signal collector 12, and then obtain the measured value of the object to be measured. Dimensions, the data transmitter is electrically connected with the processor, and is used to transmit the value of the dimension to be measured to a mobile terminal or a server. That is to say, the data collected by the signal collector 12 is sent to the processor, and the processor processes the data to obtain the measured size value of the object to be measured, and then sends the size value to the mobile device through the data transmitter. terminal or server. Optionally, the data transmitter here may be Bluetooth or a wireless network transmission structure. In addition, when the above-mentioned size value is sent to the mobile terminal, specifically, corresponding software may be installed on the mobile terminal, through which the size value may be received and displayed. In this embodiment, the dimension value obtained after measurement is no longer saved by manual recording, so that the dimension measurement effect and reliability of the object are improved.

It should be noted that the specific working process of the above processor and data transmitter can refer to the Chinese patent application with application number 201620180343.5, which will not be repeated here.
