[0002] Liquid refractive index efficient measuring device is also called refractometer, is the instrument for testing liquid concentration using light, is used to determine refractive index, birefringence, optical property, and refractive index is one of important physical constants of matter.Refraction principle of refractometer is based on the refraction of light, that is, when light enters from one medium into another medium, its propagation direction will change.Refraction determines the refractive index of sample by measuring the refraction angle of light or related optical phenomena.When measuring liquid using liquid refractive index efficient measuring device, operator needs to drop solution on refractometer prism, flatten it by cover, make solution evenly distribute on refractometer prism surface, and align instrument cover with light source, produce refraction and diffusion optical effects, read out the value on scale line through ocular, and the unit value of scale line is calculated accurately according to optical principle and mathematical theory, to obtain the actual value of measured substance content.

[0003] The existing liquid refractive index efficient measuring device is generally placed in its special storage box to protect the front refractometer prism, when user needs to measure various liquids for many times, experimenters need to frequently open storage box to take out handheld refractometer, the process is complicated, and after measured liquid is dropped on refractometer prism and cover is covered, air is brought in when cover is covered, air bubble is generated in liquid, measured liquid is not evenly covered, and detection accuracy is affected. UTILITY MODEL CONTENT

[0004] The utility model aims at providing a kind of liquid refractive index efficient measuring device, to solve the liquid refractive index efficient measuring device in the prior art in the background art proposed above when measuring liquid refractive index, and after measured liquid is dropped on refractometer prism and cover is covered, air is brought in when cover is covered, air bubble is generated in liquid, measured liquid is not evenly covered, and detection accuracy is affected.

[0005] To achieve the above object, the utility model provides the following technical scheme: a kind of liquid refractive index efficient measuring device, including lens barrel, storage part and sampling part:

[0006] One end of the lens barrel is embedded with a folding prism, the side of the lens barrel is provided with a sliding rail, the storage part is arranged outside the lens barrel, the storage part has a sliding sleeve which is slidingly nested outside the lens barrel, one end of the sliding sleeve near the folding prism is rotatably provided with a baffle, the inside of the sliding sleeve is provided with a sliding block, the sliding block is embedded in the sliding rail and is slidingly connected with the lens barrel, the sliding sleeve slides to store the folding prism into the inside of the sliding sleeve, the sampling part is arranged on the side of the lens barrel, the sampling part has a limiting frame which is fixedly arranged on the side of the folding prism, the limiting frame is slidingly provided with a prism cover plate, the top of the prism cover plate is provided with a liquid storage groove, and the prism cover plate slides to uniformly distribute the liquid in the liquid storage groove on the surface of the folding prism.

[0007] By adopting the above technical scheme, when measuring the liquid, the measured liquid can be added into the liquid storage groove, and the measured liquid can be uniformly applied on the surface of the folding prism by sliding the prism cover plate.

[0008] Overall, the nested design of the sliding sleeve and the sliding rail allows the folding prism to be completely stored in the inside of the sliding sleeve by sliding, forming a physical barrier to avoid the prism surface from being contaminated with dust or corroded due to long-term exposure. It not only protects the core optical element, but also reduces environmental interference. The rotation design of the above-mentioned baffle further enhances the sealing, which can effectively isolate the corrosion of harmful substances to the prism. When the prism cover plate slides, the liquid in the liquid storage groove is automatically spread on the surface of the folding prism through mechanical movement, replacing the traditional manual liquid dropping method. This design ensures uniform liquid coverage through the guiding action of the limiting frame, reducing measurement errors caused by uneven liquid film thickness. The capacity of the above-mentioned liquid storage groove can adapt to trace liquid.

[0009] The close nested structure of the sliding sleeve and the lens barrel ensures the stability during sliding, avoiding the introduction of optical path errors caused by mechanical vibration or deviation, and reducing the influence of mechanical errors on the optical path through structural optimization.

[0010] Preferably, the inside of the sliding sleeve is provided with a circular hole, the lens barrel passes through the circular hole and is slidingly connected with the sliding sleeve, the sliding sleeve has a hexagonal outer shape, and the surface of the sliding sleeve is provided with anti-skid lines. By adopting the above technical scheme, the sliding sleeve can slide and displace on the surface of the lens barrel.

[0011] Specifically, the circular hole in the inside of the sliding sleeve closely cooperates with the outer wall of the lens barrel to form a high-precision sliding pair, ensuring smooth displacement of the sliding sleeve along the axis of the lens barrel and avoiding deviation or shaking. The geometric constraint of the circular hole effectively suppresses the rotational freedom of the sliding sleeve during sliding, ensuring the linearity of the storage / expansion action and avoiding collision between the folding prism and the inner wall of the sliding sleeve due to lateral deviation. The hexagonal cross-section design also provides multiple gripping planes, facilitating finger force application and being more ergonomic than a cylindrical sliding sleeve.

[0012] Preferably, the slide rail is provided with two, and the two slide rails are centrally rotationally symmetric around the center of the lens barrel, the inner part of the sliding sleeve is provided with two sliding blocks, and the two sliding blocks are respectively embedded in the two slide rails and are transversely slidably connected with the lens barrel along the opening direction of the slide rail. By adopting the above technical scheme, the sliding block can be displaced in the slide rail.

[0013] Specifically, the two slide rails are designed to be symmetrically distributed around the center of the lens barrel, forming a constraint structure similar to a "double linear guide rail", which forces the sliding sleeve to slide along a single axis through two-point contact, reducing the rotational degree of freedom, and the force acting on the sliding sleeve (such as the pushing and pulling force during operation) is evenly transmitted to the slide rail through the two sliding blocks, avoiding deformation or wear of the single slide rail due to local stress concentration.

[0014] Specifically, in the present scheme, the two sliding blocks are respectively embedded in the two slide rails, forming a double guiding mechanism, so that even if a single sliding block has a slight gap due to manufacturing tolerance, the system as a whole can still maintain the straightness of the sliding track. The direction of the slide rail is strictly parallel to the axis of the lens barrel, ensuring that the sliding sleeve always maintains a constant gap with the inner wall of the sliding sleeve when it is displaced (to prevent collision or friction damage to the prism surface), and the symmetrical design of the double slide rails divides the sliding friction into four contact surfaces (two sides of each slide rail and sliding block), reducing the wear rate compared to a single slide rail system.

[0015] Preferably, the inner part of the sliding sleeve is provided with a rotating groove, the baffle is embedded in the rotating groove and rotationally connected with the sliding sleeve, and the bottom of the baffle is provided with a push plate. By adopting the above technical scheme, the baffle can be rotated by pushing the push plate.

[0016] Specifically, the design realizes one-key opening and closing operation of the baffle through the rotating connection structure of the rotating groove in the sliding sleeve and the baffle, combined with the human-computer interaction design of the bottom push plate, so that the user only needs to gently push the push plate when operating with one hand to quickly switch the opening or closing state of the baffle, which not only greatly improves the operation efficiency, but also forms a sealed protection through the complete closure of the baffle when the sliding sleeve stores the prism, effectively isolating the erosion of external pollutants such as dust and liquid splashing on the prism surface, while the limiting structure of the rotating groove ensures the precise controllability of the opening and closing angle of the baffle, avoiding excessive rotation caused by mechanical wear, and ensuring the close fit of the baffle and the end face of the sliding sleeve, thereby maintaining the stability of the internal light path of the device in a complex environment, ultimately achieving multiple technical effects of prolonging the service life of the optical element, ensuring the measurement accuracy and adapting to high-frequency detection requirements.

[0017] Preferably, the storage part further has a buckle rotationally arranged on the surface of the sliding sleeve and a clamping head arranged at the bottom of the buckle, the inner part of the sliding sleeve is provided with a rotating groove, the buckle is embedded in the rotating groove and rotationally connected with the sliding sleeve, and the buckle is provided with two. By adopting the above technical scheme, the buckle can be rotated in the inner part of the sliding sleeve to change the angle of the buckle.

[0018] Specifically, the present scheme realizes one-key quick switching of the slide sleeve between the unfolded and stored states through the elastic locking structure of the double clasp symmetrically embedded in the rotating groove of the slide sleeve, combined with the precise meshing mechanism of the clasp head and the inner clamping groove of the slide rail. The user only needs to press the clasp with one hand to overcome the spring pre-tightening force to release the engagement of the clasp head and the clamping groove. After sliding the slide sleeve to the target position, the spring automatically resets to drive the clasp to rotate, making the clasp head accurately clamped into the corresponding clamping groove. Compared with the traditional bolt fixing method, not only the operation efficiency is improved, but also the symmetrical design of the double clasp bidirectional stress effectively disperses the horizontal load of the slide sleeve during sliding, avoiding fatigue fracture caused by overload of the single clasp, ensuring that the optical prism remains in a stable exposed or sealed state under harsh working conditions such as vibration and inclination, and finally realizing high-reliability positioning of the device.

[0019] Preferably, the lens barrel further has a clamping groove a opened in the inner part of the slide rail, which is connected with the clasp head. By adopting the above technical scheme, the position of the slide sleeve can be fixed by clamping the clasp head into the clamping groove a. Specifically, the design forms a precise mechanical interlocking structure by opening the clamping groove a in the inner part of the slide rail and with the clasp head, so that when the slide sleeve is slid to the unfolded or stored preset position, the clasp head can be quickly embedded into the clamping groove a to achieve rigid fixation, not only reducing the axial movement of the slide sleeve through physical engagement, but also generating a self-locking effect by the wedge-shaped cooperation of the trapezoidal cross-section of the clamping groove a and the clasp head, ensuring that the optical prism always maintains a stable position in the measuring or storage state.

[0020] Preferably, the lens barrel further has a clamping groove b opened in the inner part of the slide rail, which is connected with the clasp head. By adopting the above technical scheme, the position of the slide sleeve can be fixed by clamping the clasp head into the clamping groove a. The design forms a double-point locking mechanism by symmetrically opening the clamping groove a and the clamping groove b in the inner part of the slide rail and with the clasp head, so that the slide sleeve can be accurately fixed at two preset positions of unfolding (measuring) and storage (protection). When the clasp head is clamped into the clamping groove a, the slide sleeve is locked in the unfolded state, ensuring that the optical prism is completely exposed and the optical path is stable. When the clasp head is clamped into the clamping groove b, the slide sleeve is locked in the storage state, forming a sealed protection with the baffle, effectively isolating external pollution. The symmetrical layout of the double clamping grooves disperses the force of the slide sleeve through the principle of force couple balance, avoiding unilateral slide rail wear, and cooperating with the self-locking wedge-shaped engagement of the clasp head and the spring pre-tightening force to realize the smooth operation of "one-key pressing-sliding-automatic locking". At the same time, the double-point rigid fixation reduces the risk of micro-displacement of the slide sleeve under vibration and impact, ultimately achieving high-precision double-state locking of the device.

[0021] Preferably, the receiving part further has a spring fixed at one end of the buckle, and the spring is located between the buckle and the lens barrel. Through the adoption of the above technical scheme, the buckle can be rotated by the elastic force provided by the spring. The design sets the spring pre-tightening mechanism between the buckle and the lens barrel, continuously drives the buckle to rotate in the locking direction by the elastic potential energy of the spring, and makes the chuck always closely engage with the clamping groove (a / b) in the slide rail, so that the automatic reset locking after the sliding sleeve slides is realized, and the cumbersome operation of manual secondary adjustment is avoided.

[0022] Preferably, the sampling part further has a sliding groove opened in the two sides of the limiting frame, and the prism cover plate is provided with a protrusion embedded in the sliding groove and in sliding connection with the limiting frame. Through the adoption of the above technical scheme, the protrusion can be displaced along the sliding groove, so that the sliding groove is opened in the two sides of the limiting frame and forms a precise sliding pair with the protrusion of the prism cover plate, the linear guidance constraint of the protrusion and the sliding groove is utilized, and the prism cover plate is ensured to slide along a strict straight line track, so that the liquid in the liquid storage tank is uniformly spread on the surface of the refracting prism through the bottom opening.

[0023] Preferably, the prism cover plate is made of transparent acrylic material, and the bottom of the liquid storage tank is designed in a through type and is communicated to the surface of the refracting prism. Through the adoption of the above technical scheme, when the measured liquid is added into the liquid storage tank, the measured liquid will flow to the surface of the refracting prism along the opening. In this way, by adopting the integrated structure of the transparent acrylic material prism cover plate and the bottom through type liquid storage tank, the measured liquid is naturally uniformly infiltrated on the surface of the refracting prism under the action of gravity through the long strip-shaped hole in the bottom of the liquid storage tank, and the high light transmittance of the acrylic material allows the operator to monitor the liquid flow state in real time, accurately identifies and eliminates air bubbles, and combines the flow guiding design of the liquid storage tank to force the liquid to spread in a single direction, thereby reducing the problems of liquid film rupture, uneven thickness and air bubble residue caused by manual smearing in the traditional drop method.

[0024] Compared with the prior art, the utility model has the advantages that: through the setting of the sampling part, when measuring liquid, the measured liquid is added into the liquid storage tank, the bottom of the liquid storage tank is provided with a long strip-shaped hole, the hole is communicated to the surface of the refracting prism, when the liquid is placed in the liquid storage tank, the liquid will contact the refracting prism through the hole due to gravity, and the measured liquid can be uniformly smeared on the surface of the refracting prism by sliding the prism cover plate, thereby preventing the accuracy of the measurement data from being affected by the air bubbles contained in the measured liquid.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] Embodiment one

[0033] Please refer to Figure 1 , Figure 2 and Figure 3 , the embodiment provides a technical solution: a liquid refractive index efficient measuring device, comprising a lens barrel 1, a sampling part 3, a limiting frame 301 and a prism cover plate 303:

[0034] One end of the lens barrel 1 is embedded with a dioptric prism 101. When using the liquid refractive index efficient measuring device to measure liquid, the operator needs to drop the solution on the dioptric prism, and make the solution evenly distributed on the surface of the dioptric prism 101, and align the instrument with the light source to produce refraction and diffusion optical effects. The numerical value on the scale line is read out through the ocular lens. The unit numerical value of the scale line is precisely calculated according to the optical principle and mathematical theory, and the actual numerical value of the measured substance content is obtained.

[0035] The prism cover plate 303 is slidably arranged in the limiting frame 301. The top of the prism cover plate 303 is provided with a liquid storage groove 305. A long hole is formed in the bottom of the liquid storage groove 305, and the hole is communicated to the surface of the dioptric prism 101. When the liquid is placed in the liquid storage groove 305, the liquid will contact the dioptric prism 101 through the hole due to gravity. The entire bottom of the liquid storage groove 305 is in a flat state to avoid abrasion of the dioptric prism 101.

[0036] The prism cover plate 303 is slid to uniformly distribute the liquid in the liquid storage tank 305 on the surface of the refract prism 101. When the liquid is measured, the measured liquid is added into the liquid storage tank 305, and the measured liquid is uniformly applied on the surface of the refract prism 101 by sliding the prism cover plate 303.

[0037] The slide grooves 302 are formed on the two sides of the limiting frame 301, and the protrusions 304 are arranged on the two sides of the prism cover plate 303. The protrusions 304 are embedded into the slide grooves 302 and are slidably connected with the limiting frame 301.

[0038] The prism cover plate 303 is abutted with the inside of the limiting frame 301 at one end of the prism cover plate 303 under the action of the liquid storage tank 305 and gravity. The bottom of the prism cover plate 303 has a gap for the liquid to flow.

[0039] The cross section of the protrusion 304 is designed as a convex block, the cross section of the slide groove 302 is designed as a concave type, and the size of the protrusion 304 is consistent with the size of the slide groove 302. Since a certain friction force is required between them, the abutting surfaces of the protrusion 304 and the slide groove 302 are rough surfaces to increase the friction force and ensure that the prism cover plate 303 does not shake with the limiting frame 301 without external force. However, the same size also ensures that the protrusion 304 can slide in the slide groove 302 with external force. The protrusion 304 and the slide groove 302 are inserted to form a sliding structure of the prism cover plate 303 and the limiting frame 301.

[0040] The protrusion 304 can be slid along the slide groove 302. The prism cover plate 303 is made of transparent acrylic material. A long hole is formed in the bottom of the liquid storage tank 305 and is connected to the surface of the refract prism 101. When the liquid is placed in the liquid storage tank 305, the liquid will contact the refract prism 101 through the hole due to gravity.

[0041] The liquid storage tank 305 at the top of the prism cover plate 303 in the liquid refractive index efficient measuring device of the embodiment is designed as a bottom-through long hole, so that the measured liquid uniformly wets the surface of the refract prism 101 under the action of gravity. Combined with the transparent acrylic material of the prism cover plate 303, the operator can monitor the liquid flow state in real time and quickly identify bubbles. The slide grooves 302 on the two sides of the limiting frame 301 and the protrusions 304 of the prism cover plate 303 form a precision sliding pair. Through the interference fit of the concave slide groove 302 and the convex protrusion 304, the prism cover plate 303 is prevented from shaking by friction force without external force. When the external force is pushed, the protrusion 304 slides linearly along the slide groove 302 to force the liquid to spread in one direction. The PTFE coating on the inner wall of the slide groove 302 reduces the sliding resistance. The flat bottom of the liquid storage tank 305 maintains a constant gap with the surface of the refract prism 101 to avoid mechanical contact and wear, and is suitable for corrosive liquid detection.

[0042] Example 2

[0043] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a high-efficiency liquid refractive index measuring device, including a housing part 2, a sliding sleeve 201, and a buckle 205.

[0044] A slide rail 102 is provided on the side of the lens barrel 1. The storage part 2 is located on the outside of the lens barrel 1. The storage part 2 has a sliding sleeve 201 that is slidably nested on the outside of the lens barrel 1. A baffle 202 is rotatably provided at one end of the sliding sleeve 201 near the refracting prism 101. A slider 204 is provided inside the sliding sleeve 201. The slider 204 is embedded in the slide rail 102 and slidably connected to the lens barrel 1. The sliding sleeve 201 slides to store the refracting prism 101 inside the sliding sleeve 201. The sampling part 3 is located on the side of the lens barrel 1. A limit bracket 301 is fixedly provided on the side of the refracting prism 101. The fixing method is an existing detachable fixing, such as bolt connection, buckle connection, etc.

[0045] The sliding sleeve 201 has a circular hole inside. The lens barrel 1 passes through the circular hole and is slidably connected to the sliding sleeve 201. The sliding sleeve 201 is hexagonal prism in shape, and the surface of the sliding sleeve 201 is engraved with anti-slip texture, which allows the sliding sleeve 201 to slide and move on the surface of the lens barrel 1.

[0046] Two slide rails 102 are provided, and the two slide rails 102 are in a central rotational symmetric structure around the center of the lens barrel 1. Two sliders 204 are provided inside the slide sleeve 201. The two sliders 204 are respectively embedded in the two slide rails 102 and are laterally slidably connected to the lens barrel 1 along the opening direction of the slide rails 102, so that the sliders 204 can move within the slide rails 102.

[0047] The sliding sleeve 201 has a rotating groove inside, such as Figure 1 and Figure 4 The rotating groove shown is located near the refracting prism 101 on the sliding sleeve 201. The baffle 202 is embedded in the rotating groove and rotatably connected to the sliding sleeve 201. A lever 203 is provided at the bottom of the baffle 202, which can be used to rotate the baffle 202 by moving the lever 203.

[0048] The storage section 2 also has a clip head 206 located at the bottom of the clip 205. The inside of the slide sleeve 201 is provided with a rotating groove. The clip 205 is embedded in the rotating groove and rotates to connect with the slide sleeve 201. There are two clips 205. The angle of the clip 205 can be changed by rotating it inside the slide sleeve 201. The inside of the slide rail 102 is provided with a slot a103.

[0049] The clamping groove a103 is in clamping connection with the clamping head 206, the clamping head 206 can be clamped into the clamping groove a103, and the position of the sliding sleeve 201 can be fixed. The clamping groove b104 is arranged in the sliding rail 102 and is in clamping connection with the clamping head 206.

[0050] The sizes of the clamping groove a103 and the clamping groove b104 are slightly larger than the size of the clamping head 206, and the size difference between the clamping groove a103, the clamping groove b104 and the clamping head 206 is not more than 1mm, so as to avoid deviation caused by gaps when plugging.

[0051] In order to fix the sliding sleeve 201, the clamping head 206 can be clamped into the clamping groove a103, and the position of the sliding sleeve 201 can be fixed. The spring 207 is arranged at one end of the buckle 205, and the recess is arranged on the outer surface of the sliding sleeve 201. The spring 207 is located in the recess to limit the transverse displacement of the spring 207. The spring 207 is located between the buckle 205 and the lens barrel 1. By pressing the end of the buckle 205 away from the clamping head 206, the buckle 205 can be rotated, so that the spring 207 is compressed and accumulates elastic force. After the buckle 205 is released, the spring 207 can release the elastic force and push the buckle 205 to rotate.

[0052] The liquid refractive index efficient measurement device is designed by sliding and nesting the sliding sleeve 201 of the receiving part 2 and the sliding rail 102 of the lens barrel 1, and the double sliding blocks 204 in the sliding sleeve 201 are embedded in the symmetrical structure of the double sliding rails 102, so that the sliding sleeve 201 can slide smoothly along the axis of the lens barrel 1. The six-prism shape of the sliding sleeve 201 and the anti-slip pattern on the surface improve the holding stability. The baffle 202 is designed to be linked with the push plate 203 through the rotating groove, so that the baffle 202 can be opened and closed by one-key rotation. The clamping head 206 at the bottom of the double buckle 205 is in engagement and locking with the clamping groove a103 and the clamping groove b104 in the sliding rail 102, and the pre-tightening force of the spring 207 automatically fixes the position of the sliding sleeve 201. The 1mm level tolerance matching between the clamping groove a103, the clamping groove b104 and the clamping head 206 reduces the shaking caused by gaps.

[0053] In use, first, the dial plate 203 is dialed to rotate the baffle 202, then the buckle 205 on both sides of the sliding sleeve 201 is pressed, the buckle 205 is rotated to overcome the elastic force of the spring 207, the clamping head 206 is moved out of the clamping groove a103, then the entire sliding sleeve 201 is slid, so that the buckle 205 is moved to the side of the clamping groove b104, then the buckle 205 is released, the spring 207 releases the elastic force and pushes the buckle 205 to rotate, so that the clamping head 206 is clamped into the clamping groove b104, thereby fixing the position of the sliding sleeve 201, and the light splitting prism 101 is exposed, then the prism cover plate 303 is slid, so that the liquid storage groove 305 is located at the bottom end of the prism 101, then the measured liquid is dropped into the liquid storage groove 305, and the prism cover plate 303 is slid upward along the sliding groove 302, in the process of sliding the prism cover plate 303, the liquid placed in the liquid storage groove 305 will contact the light splitting prism 101 through the hole due to gravity and be evenly coated on the surface of the light splitting prism 101, then the prism cover plate 303 is aligned with the light source, producing refraction and diffusion optical effects, the value on the scale line is read through the ocular lens, the unit value of the scale line is calculated according to the optical principle and mathematical theory, and the actual value of the measured substance content is obtained, after use, the sliding sleeve 201 is reset, so that the light splitting prism 101 can be stored in the sliding sleeve 201.

[0054] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
