Description

Technical Field

[0001] This utility model relates to the field of metering equipment technology, and specifically to a metering device that facilitates the reading of metering data. Background Technology

[0002] A measuring device is a device or tool used to measure, record, monitor, or evaluate a physical quantity. These devices are widely used in various industries and fields, from scientific research to industrial production. In the analysis of liquids, measuring devices are needed to quantitatively extract the liquid. Patent number CN202323349757.5 discloses a measuring device that facilitates reading measurement data, allowing workers to manually extract liquid for measurement without needing to look directly at the liquid level inside the cylinder, thus simplifying use and reading. However, when using the measuring device, a sliding block in a through-hole is used to measure the integer value inside the device. This sliding block can easily move freely within the through-hole, and simply observing the length of the sliding block protruding from the through-hole can affect the measured data. Therefore, we propose a measuring device that facilitates reading measurement data. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a measuring device that facilitates the reading of measurement data.

[0004] The technical solution adopted by this utility model to solve its technical problem is a measuring device that facilitates reading measurement data, including a ring cylinder, a measuring cylinder is clamped inside the ring cylinder, and a piston is slidably installed inside the measuring cylinder. A pull rod for lifting is clamped inside the piston, and an annular cover that fits with the ring cylinder is slidably installed on the outer periphery of the pull rod. A rotating rod that is screwed into the outer periphery of the ring cylinder and connected to the annular cover is screwed in, and there are multiple sets of rotating rods.

[0005] The outer wall surface of the ring cylinder has a groove, and a ruler is assembled in the groove. The outer periphery of the ruler is coated with scale lines for measurement, and a slider for measurement is slidably installed inside the ruler. The top surface of the slider is equipped with a pointer that matches the scale lines. A slide rod connected to the slide rod is slidably installed inside the ring cylinder, and a vertical hole is opened in the ring cover. A ring seat that is inserted into the slide rod is slidably installed on the outer periphery of the pull rod, and a fastening screw that is screwed into the slide rod is screwed onto the outer wall surface of the ring seat.

[0006] By adopting the above technical solution, during the use of the metering equipment, the piston can be moved by the pull rod in the metering cylinder to generate negative pressure and extract the liquid. At the same time, the ring cover at the top of the ring cylinder can be removed by simply unscrewing the multiple sets of screws around the outer circumference of the ring cylinder, and then the metering cylinder in the ring cylinder can be disassembled, which is convenient for replacement or cleaning. The cleaning or replacement is simple and convenient.

[0007] When using the measuring device, the pull rod pulls the piston inside the measuring cylinder to generate negative pressure and extract liquid. During this process, the pull rod can easily pull the slide rod in the cylinder through the ring seat, causing the slide rod to move and drive the slider on the scale inside the groove to move. The movement of the slider can easily drive the pointer to move, and the personnel can observe the position of the pointer on the scale line on the scale surface, thereby knowing the content of the liquid extracted inside the measuring cylinder. It is convenient to directly observe the measurement data and use the device.

[0008] Specifically, the outer wall surface of the ring cylinder is embedded with an acrylic sheet for the outer periphery of the groove, and the outer wall surface of the ring cylinder is provided with an arc-shaped groove, and there are multiple sets of arc-shaped grooves.

[0009] By adopting the above technical solution, the transparent acrylic sheet can easily protect the ruler, making it easier for people to observe while allowing the ruler and pointer to operate more stably. At the same time, the multiple sets of arc grooves on the outer circumference of the cylinder can make the cylinder more stable to hold and easier to use.

[0010] Specifically, a protective rubber ring is glued to one end of the ring cap located inside the cylinder.

[0011] By adopting the above technical solution, the rubber ring has good elasticity, which facilitates the tightening of the metering cylinder inside the ring when the ring height is increased.

[0012] Specifically, the outer wall surface of the ring is fitted with an elastic rope for limiting the position, and the end of the elastic rope away from the ring is fitted with a protective end.

[0013] By adopting the above technical solution, the elastic rope makes the drum head easy to move, so that the drum head can be locked onto the feed end of the metering cylinder and protected. It is also easy to disassemble, and the elastic rope can prevent the drum head from falling off after disassembly, making it convenient for reuse next time.

[0014] Specifically, a leak-proof rubber sleeve is glued inside the cylinder head.

[0015] By adopting the above technical solution, the rubber sleeve in the cylinder head has good elasticity, which facilitates the improvement of the tightness of the cylinder head connection.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of a measuring cylinder, piston, pull rod, ring cover and rotary rod, allows the piston to be moved by the pull rod in the measuring cylinder during the use of the measuring equipment, thereby generating negative pressure and extracting liquid. At the same time, by simply unscrewing the multiple sets of rotary rods around the outer circumference of the ring cylinder, the ring cover at the top of the ring cylinder can be removed, and then the measuring cylinder in the ring cylinder can be disassembled, which is convenient for replacement or cleaning, and the cleaning or replacement is simple and convenient.

[0018] 2. The technical solution of this application, through the design of grooves, rulers, sliding rods, sliders, pointers, scale lines, ring seats, fastening screws, and vertical holes, allows the metering equipment to operate smoothly. During the process of using the metering device, the pull rod pulls the piston inside the metering cylinder to generate negative pressure and extract liquid. Simultaneously, the pull rod easily pulls the sliding rod inside the ring cylinder via the ring seat, causing the sliding rod to shift and move the slider on the ruler inside the groove. This movement of the slider facilitates the movement of the pointer, allowing personnel to observe the position of the pointer on the scale line on the ruler surface. This enables the determination of the liquid content extracted from the metering cylinder and facilitates direct observation of measurement data, making the device convenient to use.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please see Figure 1-4This utility model provides a technical solution: a measuring device for easy reading of measurement data, including a ring cylinder 1, a measuring cylinder 2 inserted into the ring cylinder 1, a piston 3 slidably installed inside the measuring cylinder 2, a pull rod 4 for lifting inserted into the piston 3, and an annular cover 5 that fits into the ring cylinder 1 slidably installed on the outer periphery of the pull rod 4. A rotating rod 6 that is screwed into the annular cover 5 is screwed onto the outer periphery of the ring cylinder 1, and there are multiple sets of rotating rods 6. A groove 7 is formed on the outer wall surface of the ring cylinder 1, and the groove 7 is equipped with... The device includes a ruler body 8, with scale lines 12 coated on its outer periphery for measurement. A slider 10 for measurement is slidably installed inside the ruler body 8, and a pointer 11 adapted to the scale lines 12 is mounted on the top surface of the slider 10. A slide rod 9 connected to the slider 10 is slidably installed inside the ring cylinder 1, and a vertical hole 15 is opened inside the ring cover 5. A ring seat 13 that is inserted into the slide rod 9 is slidably installed on the outer periphery of the pull rod 4, and a fastening screw 14 that is screwed into the slide rod 9 is screwed onto the outer wall surface of the ring seat 13.

[0027] When using the metering equipment, the piston 3 can be moved by the pull rod 4 in the metering cylinder 2 to generate negative pressure and extract the liquid. At the same time, the ring cover 5 on the top of the ring cylinder 1 can be removed by simply unscrewing the multiple sets of rotating rods 6 on the outer circumference of the ring cylinder 1. Then the metering cylinder 2 in the ring cylinder 1 can be disassembled, which is convenient for replacement or cleaning. The cleaning or replacement is simple and convenient.

[0028] When using the measuring device, the pull rod 4 pulls the piston 3 inside the measuring cylinder 2 to generate negative pressure and extract liquid. During this process, the pull rod 4 can easily pull the slide rod 9 in the ring cylinder 1 through the ring seat 13, causing the slide rod 9 to move and drive the slider 10 on the scale body 8 inside the groove 7 to move. The movement of the slider 10 can easily drive the pointer 11 to move, and the personnel can observe the position of the pointer 11 on the scale line 12 on the surface of the scale body 8, thereby knowing the content of the liquid extracted inside the measuring cylinder 2, and easily observing the measurement data, making it convenient to use.

[0029] like Figure 1 and Figure 2 As shown, an acrylic sheet 17 for the outer periphery of the groove 7 is embedded in the outer wall surface of the ring cylinder 1, and an arc-shaped groove 21 is opened on the outer wall surface of the ring cylinder 1, and there are multiple sets of arc-shaped grooves 21.

[0030] When in use, the transparent acrylic sheet 17 provides convenient protection for the ruler 8, making it easy for personnel to observe while allowing the ruler 8 and pointer 11 to operate more stably. At the same time, the multiple sets of arc grooves 21 on the outer periphery of the ring cylinder 1 make the ring cylinder 1 more stable to hold and easy to use.

[0031] like Figure 2 and Figure 4As shown, the end of the ring cover 5 located inside the ring cylinder 1 is glued with a protective rubber ring 16.

[0032] When in use, the rubber ring 16 has good elasticity, which facilitates the tightening of the metering cylinder 2 inside the ring cylinder 1 when the ring height is increased.

[0033] like Figure 1 As shown, the outer wall surface of the cylinder 1 is fitted with an elastic rope 18 for limiting the position, and the end of the elastic rope 18 away from the cylinder 1 is fitted with a protective cylinder head 19.

[0034] During use, the elastic rope 18 makes it easy to move the drum head 19, so that the drum head 19 can be locked onto the feed end of the metering cylinder 2 and protected. It is also easy to disassemble. After disassembly, the elastic rope 18 can prevent the drum head 19 from falling off, making it convenient to use it again next time.

[0035] like Figure 1 and Figure 2 As shown, a leak-proof rubber sleeve 20 is glued inside the cylinder head 19.

[0036] When in use, the rubber sleeve 20 in the cylinder head 19 has good elasticity, which makes it easier to improve the tightness of the cylinder head 19 after connection.

[0037] The working principle and usage process of this utility model are as follows: In use, first install the corresponding structural components in the appropriate positions. During the use of the measuring device, the pull rod 4 in the measuring cylinder 2 pulls the piston 3 to move, thereby generating negative pressure and extracting liquid. Simultaneously, simply unscrew the multiple sets of rotating rods 6 around the outer circumference of the ring cylinder 1 to remove the ring cover 5 at the top of the ring cylinder 1. Then, the measuring cylinder 2 inside the ring cylinder 1 can be disassembled for easy replacement or cleaning. The cleaning or replacement is simple and convenient. During the use of the measuring device, as the pull rod 4 pulls the piston 3 inside the measuring cylinder 2 to generate negative pressure and extract liquid, the pull rod 4 conveniently pulls the sliding rod 9 in the ring cylinder 1 through the ring seat 13. This causes the sliding rod 9 to shift and move the slider 10 on the ruler 8 inside the groove 7. The movement of the slider 10 conveniently moves the pointer 11, allowing personnel to observe the position of the pointer 11 on the scale line 12 on the surface of the ruler 8, thereby understanding the content of liquid extracted inside the measuring cylinder 2 and facilitating direct observation of measurement data for convenient use.
