Description

Technical Field

[0001] The utility model relates to the technical field of oil product kinematic viscosity detection devices, in particular to a novel oil product kinematic viscosity analysis and detection instrument. Background Art

[0002] The kinematic viscosity of oil is a physical quantity that describes the resistance of oil to flow when subjected to shear force. It is usually used to evaluate the fluidity of oil and its internal friction at a specific temperature. The kinematic viscosity is usually expressed as the ratio between the speed at which the oil flows under gravity at a certain temperature and the shear stress applied to it. The kinematic viscosity of oil is an important performance indicator.

[0003] The existing oil kinematic viscosity analysis and testing instrument is generally divided into two parts, the analysis and testing instrument body and a large number of viscosity tubes of various models. The viscosity tube is used to absorb the oil. When the existing viscosity tube absorbs the oil, the operator generally manually connects the air bag to the viscosity tube, and then the operator uses a finger to block an opening of the viscosity tube and sucks the oil into the viscosity tube through the negative pressure of the air bag. The operation is not convenient enough, and the amount of oil absorbed needs to be controlled by the operator according to his own experience, which is inconvenient to use the device.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The utility model provides a technical solution: Figure 1 and Figure 2 The utility model discloses a novel oil product kinematic viscosity analysis and detection instrument, including a viscosity tube 1 installed in a water bath of the oil product kinematic viscosity analysis and detection instrument body. Generally, the oil product kinematic viscosity analysis and detection instrument is mainly divided into an instrument body and a viscosity tube 1, and the viscosity tube 1 is passed through the water bath of the instrument body, and a material taking piece 2 is connected to one end of the viscosity tube 1 away from the water bath;

[0024] The material taking member 2 comprises a guide rod 21, a piston plate 22 and a quantitative unit 23, wherein the piston plate 22 is connected to the viscosity tube 1, and the guide rod 21 is installed at the bottom of the piston plate 22, and extends away from the viscosity tube 1 to the direction directly below the viscosity tube 1 and is equipped with a limit plate 24;

[0025] The quantitative unit 23 includes a bracket and a driving member 232. The bracket is composed of a circular ring 2311 and a plurality of square rods 2312, wherein the plurality of square rods 2312 are located below the piston plate 22 and are fixedly connected to the inner wall of the viscosity tube 1. The guide rod 21 passes through the circular ring 2311 and is slidably connected to the circular ring 2311. Two slide grooves 233 are relatively provided on the circumferential side of the guide rod 21. A slider 234 is slidably connected in the slide groove 233. A side wall of the slider 234 away from the slide groove 233 extends outward to form a blocking portion 235. The driving member 232 is installed in the limiting plate 24 and extends upward into the slide groove 233 to drive the slider 234 to perform reciprocating linear motion.

[0026] In this embodiment, the driving member 232 is used to change the height of the slider 234 in the slide groove 233, and the blocking portion 235 is used to generate a conflict with the bracket to control the stroke of the piston plate 22 in the viscosity tube 1. While facilitating the detection of oil products, the amount of oil products sucked can also be controlled to improve the detection accuracy. When operating the analyzer, only the limit plate 24 needs to be pressed to complete the operation. Compared with the traditional operation method, it is more convenient and more practical.

[0027] Specifically, in this embodiment, when testing is performed, especially when oil needs to be sucked, by applying a force to the limit plate 24, the piston plate 22 can be driven to perform piston movement in the viscosity tube 1 through the transmission of the guide rod 21, so that the end of the viscosity tube 1 away from the piston plate 22 generates suction to suck the oil, and due to the setting of the quantitative unit 23, the stroke of the piston plate 22 can be controlled to achieve the control of the amount of oil sucked, specifically, the driving member 232 drives the slider 234 to perform reciprocating linear motion along the height direction of the slide groove 233, that is, the height of the slider 234 can be changed, which is manifested as the farther the slider 234 is from the bracket, the greater the oil absorption amount, and vice versa, the smaller the oil absorption amount, so the blocking portion 235 integrally formed with the slider 234 can produce motion conflict with the bracket, causing the running height of the guide rod 21 to change, thereby achieving the above purpose;

[0028] It is further explained that the bracket is composed of a circular ring 2311 and a plurality of square rods 2312, and the plurality of square rods 2312 are fixedly connected to the inner wall of the viscosity tube 1, and the guide rod 21 passes through the circular rod, and there is a sliding connection relationship between the two, which can limit the movement trajectory of the guide rod 21, allowing it to maintain linear movement, prevent deviation from causing stress concentration at the connection point between it and the piston plate 22, and improve the service life of the piston plate 22. At the same time, the blocking part 235 formed by the part of the slider 234 extending out of the slide groove 233, its contact surface with the circular ring 2311 is preferably surface contact, and two blocking parts 235 are provided, so that the force is evenly distributed during operation, which is further convenient for the operator to use.

[0029] In some preferred embodiments, scale lines may be provided in parallel along the height of the slide groove, thereby further improving the effect of controlling the oil absorption amount.

[0030] In a further preferred embodiment of the present invention, Figure 2 and Figure 4 As shown, the driving member 232 includes a threaded rod 2321, and the number of the threaded rods 2321 is set to two, and the two threaded rods 2321 are respectively rotatably installed in the two sliding grooves 233, and each threaded rod 2321 is respectively threadedly connected with the corresponding slider 234, and a driving groove 2322 is opened in the limiting plate 24, and a main gear 2323 and two driven gears 2324 are rotatably connected in the driving groove 2322, and the two side walls of the main gear 2323 and the two driven gears 2324 are both fitted with the inner wall of the driving groove 2322, so that there is a certain friction force between the two side walls of the main gear 2323 and the two driven gears 2324 and the inner wall of the driving groove 2322, wherein the two driven gears 2324 are located on both sides of the driving gear, and are respectively coaxially fixedly connected with the ends of the corresponding threaded rods 2321, and the driving gear is meshed with the two driven gears 2324;

[0031] In this embodiment, a driving groove 2322 is selected to be provided in the limit plate 24 in order to provide an installation space for the installation of the driving member 232. Specifically, during installation, the driving gear is coaxially arranged with the guide rod 21, and the two driven gears 2324 are coaxially fixedly arranged with the threaded rod 2321 at the corresponding position, and the driving gear is meshed with the driven gear 2324. In this way, when the driving gear rotates, the two driven gears 2324 can be synchronously driven to rotate, thereby driving the two threaded rods 2321 to rotate synchronously. Since the threaded rod 2321 is rotatably installed in the slide groove 233 and is threadedly connected with the slider 234, as the threaded rod 2321 rotates, since the slider 234 does not have the ability to rotate, it can only slide up or down with the rotation of the threaded rod 2321, thereby achieving the purpose of changing the height of the slider 234.

[0032] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, a knob 2325 is installed on one side of the driving gear, and a notch is opened on the side wall of the limiting plate 24 corresponding to the position of the knob 2325, and the knob 2325 is inserted into the notch;

[0033] In this embodiment, the operator rotates the knob 2325 to drive the driving gear to rotate, thereby realizing the start or stop of the entire driving member 232. It should be further explained that the height of the knob 2325 does not exceed the groove depth of the notch. The purpose of this is to prevent the possibility of accidentally hitting the knob 2325 when pressing the limit plate 24, thereby avoiding changes in the accuracy of the oil suction amount.

[0034] In a further preferred embodiment of the present invention, Figure 1 and Figure 2 As shown, the outer sleeve of the guide rod 21 is provided with a return spring 3, and the two ends of the return spring 3 are fixedly connected to the limit plate 24 and the ring 2311 respectively, and a gap is left between the return spring 3 and the blocking portion 235;

[0035] In this embodiment, each time the oil is sucked, as the piston plate 22 moves up or down, the return spring 3 is released or compressed. Figure 2 As shown, the return spring 3 is in a released state, and the piston plate 22 is at the lowest point of the stroke. When the piston plate 22 moves upward, the return spring 3 is in a continuously compressed state. When the oil suction is completed, the return spring 3 is about to be released. With the cooperation of the operator, the piston plate 22 can be returned to the initial position more quickly to prepare for the next oil suction.

[0036] In a further preferred embodiment of the present invention, Figure 2 As shown, an air inlet pipe is arranged on the outer peripheral side of the viscosity tube 1, and a plug 4 is connected to the air inlet pipe. The plug 4 is arranged in a hemispherical shape at one end of the viscosity tube 1, and an anti-drop rope 5 is arranged between the other end of the plug 4 and the outer wall of the viscosity tube 1.

[0037] In this embodiment, the air pressure in the viscosity tube 1 can be controlled by controlling the opening or closing of the air intake pipe. Specifically, when the air intake pipe is opened, the piston plate 22 continues to move downward, and the piston plate 22 forms an extrusion force on the plug 4, squeezing the plug 4 in a direction away from the opening of the air intake pipe, squeezing the plug 4 out of the air intake pipe, and realizing air intake of the air intake pipe. At this time, the air pressure in the viscosity tube 1 is consistent with the outside world, and the oil in the viscosity tube 1 is in a state of free dripping. It should be noted that this operation is performed after the oil is absorbed, so the piston plate 22 continues to move downward, and the viscosity tube 1 no longer absorbs oil, so it will not affect the oil absorption amount. An anti-drop rope 5 is provided to prevent the plug 4 from being lost.

[0038] In a further preferred embodiment of the present invention, Figure 3 As shown, the part of the plug 4 located in the viscosity tube 1 is located between the piston plate 22 and the bracket, and an annular extrusion portion 6 is provided at the bottom of the piston plate 22 corresponding to the position of the hemispherical surface of the plug 4;

[0039] In this embodiment, the plug 4 is inserted into the opening of the intake pipe, and part of it is located in the viscosity tube 1. When the piston plate 22 continues to be acted upon, the annular extrusion portion 6 and the hemispherical part of the plug 4 can be used to produce extrusion, and the plug 4 can be squeezed out using the inclined surface, so that the gas inside and outside the viscosity tube 11 can be exchanged automatically through the intake pipe 2.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
