Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, the embodiments of the present utility model will be described in further detail with reference to the accompanying drawings.
The embodiment provides a device for measuring the length of a drainage tube, see fig. 1, which device mainly consists of a measuring device 1, a fixing device 2 and a holder 3.
The measuring device 1 comprises a measuring wheel 11, a first gear 12, a second gear 13, a driving shaft 14 and a driven shaft 15. The measuring wheel 11 and the first gear wheel 12 are both mounted on a driving shaft 14, while the second gear wheel 13 is mounted on a driven shaft 15. The circumference of the measuring wheel 11 corresponds to the maximum scale value on the first gear 12, so that the measuring accuracy can be ensured. 10 scales are uniformly arranged on each of the two gears, and the scales can intuitively represent the length of the drainage tube. Furthermore, a pointer is fixed to the driving shaft 14 and the driven shaft 15 for pointing to the scale on the gear.
The fixing device 2 comprises an upper arc-shaped portion 21 and a lower arc-shaped portion 22, which form an arc-shaped structure. The upper arc 21 is integral with the top of the support 3, while the lower arc 22 is connected to a connection 33 at the top inside the support 3 by a spring 34, the lower spring 34 having two functions: firstly, prevent that lower arc portion 22 drops after extracting the spacing nail, secondly, make lower arc portion 22 can more easily upwards adjust in order to adapt to the drainage tube of different diameters. The pulley 4 is sleeved on the lower arc-shaped part 22, so that inconvenience in measurement caused by friction during measurement is avoided.
The support 3 is internally provided with a sliding rail 31 and a sliding groove, and the lower arc-shaped part 22 passes through the sliding groove to be connected with the sliding rail 31. When the position of the lower arc-shaped part 22 needs to be adjusted to adapt to drainage tubes with different tube diameters, the lower arc-shaped part 22 can slide on the slide rail 31. After being adjusted to the proper position, we can fix the lower arc 22 by inserting the limiting nails into the limiting holes 32 on the bracket 3 corresponding to the sliding rails 31. This limiting pin is connected to the bracket 3 by means of a connecting spring, ensuring the stability of the lower arc 22 after adjustment. The arrangement of the connecting spring serves two purposes: firstly, prevent to inject the nail and lose after taking out, secondly, utilize its elasticity, can be according to the degree of depth that inject spacing hole 32 of inject the nail, adjust the position of lower arc portion 22 to adapt to the drainage tube of different diameters.
Both ends of a driving shaft 14 and a driven shaft 15 of the device are connected with the fixing device 2 through bearings. The two ends of the driving shaft 14 are connected with the upper arc-shaped part 21 through bearings, the two ends of the driven shaft 15 are connected with the upright post 23 through bearings, and the upright post 23 is of an integrated structure with the upper arc-shaped part 21 and the top of the bracket 3. This design allows the gear system to operate smoothly and accurately represent the length of the drain tube.
Application instance
In one operation, we need to measure the length of one drainage tube. The diameter of the drainage tube was 2cm. First, we need to install the drain tube between the upper and lower curved portions 21 and 22 of the fixture 2. Because the lower arcuate portion 22 can slide on the slide rail 31, we can adjust its position to accommodate this 2cm drain tube. When adjusted in place, we secure the lower arcuate portion 22 by inserting a restraining pin into the restraining aperture 32.
Next, we place the measuring wheel 11 on the draft tube and then slide the measuring wheel 11 along the length of the draft tube. Since the circumference of the measuring wheel 11 is 10cm, when the measuring wheel 11 rotates one revolution, the first gear 12 also rotates one revolution, and accordingly the pointer will point to the scale 1 on the first gear 12, indicating that 10cm is measured. If the measuring wheel 11 continues to rotate, when it is rotated to the starting position of the second turn, the first gear 12 will rotate to the next scale and the second gear 13 will also rotate to the scale 1, which means that the length of the draft tube exceeds 10cm.
For example, if we need to measure a 25cm drainage tube. When the measuring wheel 11 slides for the whole length of the draft tube, the first gear 12 will rotate two and a half turns, i.e. the pointer will point to the scale 5, while the second gear 13 rotates two divisions, i.e. the pointer points to the scale 2. Thus, the length of the drainage tube can be intuitively read out to be 25cm.
The design is simple and effective, the length of the drainage tube can be conveniently and rapidly measured, complex tools or instruments are not needed, and complex calculation is not needed.
In other embodiments, the circumference of the measuring wheel can be selected according to the requirements, and meanwhile, the number of gears can be selected according to the requirements to meet the measurement of the length of the drainage tube.
The foregoing is only illustrative of the present utility model and is not to be construed as limiting thereof, but rather as various modifications, equivalent arrangements, improvements, etc., within the spirit and principles of the present utility model.
