Technical Field

[0001] The utility model relates to the technical field of viscosity detection equipment, in particular to a portable viscosity measuring device. Background Art

[0002] Viscosity, as a physical quantity that measures the viscosity of a fluid, is an important indicator of liquid fluids. In actual engineering and industrial production, it is often necessary to detect the viscosity of the fluid on-site to ensure the best process operating environment and product quality, thereby improving production efficiency.

[0033] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the elements in the drawings are drawn only as examples and not necessarily according to the true scale.

[0034] Figure 1 The structure of the portable viscosity measuring device in one embodiment of the present invention is shown. For ease of description, the accompanying drawings only show structures related to the embodiment of the present invention.

[0035] See also Figure 1 The portable viscosity measuring device 100 in a preferred embodiment of the present invention includes a frame 110 and a measuring column 120 .

[0036] Please also refer to Figure 2 The frame 110 has an operating surface 111. A groove 112 is formed on the operating surface 111. The groove 112 is formed on an integral part by machining or integral molding, or is a cavity with one end open formed by fixing multiple parts together by welding, screwing, etc.

[0037] The measuring column 120 has a detection end 122 and a mounting end 121. The mounting end 121 is located within the groove 112 and is rotatably connected to the frame 110, allowing the measuring column 120 to be retracted laterally within the groove 112 or the detection end 122 to be tilted outwardly, outside the groove 112. The measuring column 120 is used to perform viscosity testing on a liquid to obtain a viscosity parameter of the liquid.

[0038] When the portable viscosity measuring device 100 is on a horizontal plane, the operating surface 111 is the upper surface of the frame 110. At this time, the groove 112 is a groove with an opening facing upward. When the measuring column 120 is flipped so that the detection end 122 is located outside the groove 112, the measuring column 120 is in an upright state with the detection end 122 at the top and the mounting end 121 at the bottom.

[0039] When viscosity testing is required, the portable viscosity measuring device 100 is manually or automatically flipped over the detection end 122 to the outside of the groove 112 to upright the measuring column 120. The liquid to be tested is then dripped into the detection port of the detection end 122 to perform viscosity measurement. When viscosity testing is not required, the detection end 122 is manually or automatically flipped over to the inside of the groove 112 to place the measuring column 120 horizontally within the groove 112. This reduces the height of the portable viscosity measuring device 100 when not in use, thereby achieving the purpose of reducing its size and making it easier to carry. Therefore, the portable viscosity measuring device 100 is easy to use and carry, and can meet the needs of rapid on-site testing.

[0040] Specifically, the projection shape of the groove 112 on the operating surface 111 is a rectangle, so as to facilitate the flipping of the measuring column 120 in the groove 112 while ensuring that the groove 112 is compatible with the measuring column 120 placed horizontally in the groove 112, which is conducive to further reducing the volume of the portable viscosity measuring device 100.

[0041] Of course, in other embodiments, the orthographic projection shape of the groove 112 on the operating surface 111 can also be other shapes such as circle, ellipse, etc., as long as the measuring column 120 can be normally flipped in the groove 112 and can accommodate the horizontally placed measuring column 120.

[0042] Please also refer to Figure 2 and Figure 3 In some embodiments, the frame 110 includes a panel 113 having an operating surface 111 and a trough shell 114 having a hollow structure. A communication port 1131 is provided on the operating surface 111. The trough shell 114 is installed on the side of the panel 113 away from the operating surface 111. The trough shell 114 is aligned with and connected to the communication port 1131 to form a groove 112. The frame 110 is configured as a panel 113 and a trough shell 114, and the trough shell 114 is fixed to the panel 113 to form the groove 112 with the opening located on the operating surface 111, so that the mass of the frame 110 is small, which is conducive to lightweighting of the portable viscosity measuring device 100 and makes the portable viscosity measuring device 100 more convenient to carry.

[0043] Please also refer to Figure 4 Furthermore, in some embodiments, the mounting end 121 has a rotational mounting point 123 and a sliding portion 124. In the depth direction of the groove 112, the rotational mounting point 123 and the sliding portion 124 are spaced apart, and the rotational mounting point 123 is located below the sliding portion 124. A clearance notch 1141 is defined at one end of the groove shell 114 near the mounting end 121, extending through the sidewall of the groove shell 114.

[0044] The portable viscosity measuring device 100 also includes a tilting mechanism 130. This mechanism 130 comprises a tilting push plate 131 and a mounting plate 132 fixed to the bottom of the tank housing 114. The mounting point is pivotally connected to one end of the tilting push plate 131 through a clearance notch 1141. The other end of the tilting push plate 131 is mounted on the mounting plate 132. The tilting push plate 131 is movable relative to the mounting plate 132 along a straight line parallel to the operating surface 111.

[0045] A guide slot 115 is formed on the inner wall of the groove 112 at a position opposite the sliding portion 124. The guide slot 115 is tilted downward relative to the operating surface 111 in the direction from the rotational mounting point 123 to the mounting horizontal plate 132. The sliding portion 124 is movably disposed in the guide slot 115.

[0046] When the measuring column 120 needs to be switched from the horizontal placement state to the vertical upright state, an upward external force needs to be applied to the detection end 122. Under the action of the external force, the measuring column 120 is driven to rotate around the rotating mounting point 123. At this time, the sliding portion 124 moves in an oblique downward direction in the guide inclined groove 115. The flip push plate 131 moves along the rotating mounting point 123 toward the mounting horizontal plate 132 under the push of the mounting end 121 until the detection end 122 reaches the outside of the groove 112. The entire detector is in a vertical upright state, which facilitates viscosity testing of the liquid to be tested.

[0047] When the detector needs to be switched from a vertical upright state to a horizontal placement state, an external force needs to be applied to the detection end 122 in the direction of the groove 112, so that under the action of the external force, the detector is driven to rotate around the rotating mounting point 123. At this time, the sliding portion 124 moves in an inclined upward direction in the guide inclined groove 115, and the flip push plate 131 moves along the rotating mounting point 123 away from the mounting horizontal plate 132 under the pulling action of the mounting end 121 until the detection end 122 enters the groove 112. The entire detector is completely horizontally placed in the groove 112, and the detector is completely retracted into the groove 112.

[0048] In summary, the sliding portion 124 cooperates with the guide chute 115, and the rotational mounting point 123 cooperates with the flip push plate 131 to provide two-point support for the measuring column 120 in its flipping direction, ensuring a relatively smooth and reliable flipping process for the measuring column 120. Furthermore, when the mounting end 121 rotates relative to the rotational mounting point 123, it pushes or pulls the flip push plate 131 to move laterally relative to the mounting cross plate. The sliding portion 124 slides along the inclined direction within the guide chute 115, ensuring that the measuring column 120 can flip normally. Furthermore, the area of ​​the groove 112 parallel to the operating surface 111 is relatively small, which further reduces the size of the portable viscosity measuring device 100.

[0049] Furthermore, in some embodiments, a guide wheel 133 is mounted on one end of the flip push plate 131 away from the rotation mounting point 123. A guide rail 134 is provided on the mounting horizontal plate 132. The guide rail 134 extends in a straight line parallel to the operating surface 111. The guide wheel 133 and the guide rail 134 are in rolling engagement to movably mount the flip push plate 131 on the mounting horizontal plate 132.

[0050] During the flipping process of the measuring column 120, the guide wheel 133 rolls on the guide rail 134, which not only guides the moving direction of the flip push plate 131 on the mounting cross plate 132, but also ensures that the flip push plate 131 moves more smoothly on the mounting cross plate 132, making the flipping action of the measuring column 120 smoother and more flexible, and reducing the probability of the measuring column 120 getting stuck during the flipping process.

[0051] Furthermore, in some embodiments, guide rails 134 are provided on opposite sides of the mounting plate 132 in a transverse direction perpendicular to the extension direction of the guide rails 134. Two sets of guide wheels 133 are spaced apart at the bottom of the flip push plate 131. Each set of guide wheels 133 includes at least one guide wheel 133. The two sets of guide wheels 133 are arranged transversely and respectively engage in rolling engagement with the two guide rails 134 in a one-to-one correspondence. That is, each guide rail 134 engages in rolling engagement with at least one guide wheel 133.

[0052] In this way, the flip push plate 131 is located above the mounting cross plate 132, and the two guide wheels 133 are respectively located on two pairs of sides of the mounting cross plate 132 and respectively roll in cooperation with the guide rails 134 located on both sides of the mounting cross plate 132, so as to further reduce the height of the frame 110, thereby making the volume of the portable viscosity measuring device 100 smaller. At the same time, the two sets of guide wheels 133 respectively roll in cooperation with the two guide rails 134 to improve the movement stability of the flip push plate 131 on the mounting cross plate 132, further improving the stability of the measuring column 120 during the flipping process.

[0053] Furthermore, in some embodiments, the sliding portion 124 includes a connecting rod 1241 and a sleeve 1242. One end of the connecting rod 1241 is fixed to the side of the mounting end 121, and the other end is rotatably mounted on the sleeve 1242. The sleeve 1242 is rollably mounted in the guide chute 115.

[0054] When the sliding portion 124 moves in the guide chute 115, the sleeve 1242 rotates relative to the connecting rod 1241 and rolls in the guide chute 115 to improve the smoothness of the sliding portion 124 when moving in the guide chute 115, further improving the stability and flexibility of the flipping action of the measuring column 120.

[0055] Furthermore, in some embodiments, the frame 110 further includes a reinforcing plate 116. One end of the reinforcing plate 116 is fixed to the side of the panel 113 facing away from the operating surface 111 and is affixed to the outer wall of the tank shell 114 near the mounting end 121. A guide chute 115 is defined in the sidewall of the recess 112, extending through the inner wall of the tank shell 114 and the outer wall of the reinforcing plate 116.

[0056] The shaft sleeve 1242 has a flange on one side. Two opposing shaft sleeves 1242 are rotatably mounted on the connecting rod 1241. The flanges of the two shaft sleeves 1242 are located on the inner and outer sides of the reinforcement plate 116, or on the inner side of the tank shell 114 and the outer side of the reinforcement plate 116. Therefore, the reinforcement plate 116, or the sidewalls of the reinforcement plate 116 and the tank shell 114, are located between the two flanges. This prevents the guide wheel 133 from sliding out of the guide chute 115 during the sliding movement of the sliding portion 124 within the guide chute 115, thereby improving the reliability of the portable viscosity measuring device 100.

[0057] During the manufacturing process of the portable viscosity measuring device 100, even if the tank shell 114 adopts a thin plate structure, the provision of the reinforcing plate 116 can ensure that the sliding portion 124 can slide stably and reliably in the guide chute 115. While taking into account the structural stability, it is also conducive to further reducing the weight of the portable viscosity measuring device 100.

[0058] Please also refer to Figure 5 Furthermore, in some embodiments, the bottom wall of the tank housing 114 can undergo elastic deformation under pressure. The portable viscosity measuring device 100 also includes a locking mechanism 140. The locking mechanism 140 includes a locking member 141 fixed to the bottom of the tank housing 114 and a locking seat 142 fixed to the flip push plate 131. The locking member 141 has a locking portion 1411. The locking seat 142 has a locking engagement portion 1421.

[0059] When the measuring column 120 is laterally retracted into the groove 112, the locking portion 1411 cooperates with the locking engagement portion 1421 to lock the position of the flip push plate 131. The elastic deformation of the bottom wall of the groove housing 114 drives the locking member 141 to move up and down until the locking portion 1411 is released from the locking seat 142.

[0060] During the process of switching the measuring column 120 from the vertical upright state to the horizontal placement state, the flip push plate 131 drives the locking seat 142 to move in the direction toward the locking member 141 until the measuring column 120 is completely placed horizontally in the groove 112. The locking portion 1411 and the locking matching portion 1421 cooperate with each other to achieve the locking of the locking member 141 and the locking seat 142 to lock the position of the flip horizontal plate, thereby preventing the detection end 122 of the measuring column 120 from flipping out of the groove 112 when the viscosity measurement is not required during the carrying or transportation process.

[0061] When it is necessary to switch the measuring column 120 from a horizontal placement state to a vertical upright state, the staff can gently press the detection end 122, so that the bottom of the groove shell 114 undergoes elastic deformation under the downward pressure of the detection end 122. At this time, the locking part 141 will move up and down with the bottom of the groove shell 114, thereby causing the locking part 1411 to disengage from the locking mating part 1421, realizing the unlocking function of the locking mechanism 140, and facilitating the outward flipping of the measuring column 120.

[0062] Specifically, the locking mechanism 140 also includes a locking spring (not shown). One of the locking portions 1411 and the locking mating portion 1421 forms a locking groove, and the other of the locking portion 1411 and the locking mating portion 1421 forms a locking head. The locking spring is operably connected to the locking head and is used to drive the locking head to rotate in the direction of movement of the flip push plate 131, thereby disengaging the locking head from the locking groove. The locking spring may be a torsion spring, a compression spring, a metal spring, or the like.

[0063] When the measuring column 120 switches from the vertical upright state to the horizontal placement state, the flip push plate 131 drives the locking member 141 to move in the direction toward the locking seat 142 until the locking member 141 overcomes the elastic force provided by the locking elastic member under the pushing action of the flip push, so as to clamp the locking head into the locking groove to realize the locking function; when the measuring column 120 switches from the horizontal placement state to the vertical upright state, the bottom of the groove shell 114 undergoes elastic deformation under the pressing force exerted on the measuring column 120, so as to drive the locking member 141 to move up and down, so that the locking head also moves up and down, until the locking head disengages from the locking groove under the elastic force provided by the locking elastic member to realize the unlocking function.

[0064] Of course, in other embodiments, the locking portion 1411 and the locking matching portion 1421 in the locking mechanism 140 may also be other structures, such as a hook structure with elastic deformation performance, etc.

[0065] Furthermore, in some embodiments, the flip mechanism 130 further includes an upright elastic member (not shown). The upright elastic member is used to provide an elastic force that drives the flip push plate 131 to slide toward the mounting horizontal plate 132. The upright elastic member can be a spring, an elastic rubber band, a metal spring, etc.

[0066] When viscosity testing is required, under the action of the elastic force provided by the upright elastic member, the flip push plate 131 moves in the direction toward the mounting cross plate 132, and at the same time, the sliding portion 124 slides in the downwardly inclined direction in the guide inclined groove 115, so that the measuring column 120 automatically switches from the horizontal placement state to the vertical upright state, and ensures that the measuring column 120 can stably maintain the upright state, thereby improving the reliability of the viscosity measurement.

[0067] Specifically, the upright elastic member is a spring, and its two free ends are connected to the flip push plate and the mounting cross plate, respectively. More specifically, a first fixing member 135 for hooking the elastic member is fixed to the flip push plate 131. The mounting cross plate 132 is fixed to the bottom of the tank housing 114 via a second fixing member 119. The other end of the upright elastic member is hooked to the second fixing member 119.

[0068] Of course, in other embodiments, the upright elastic member is a spring, and one free end of the upright elastic member can also be directly fixed to the flip push plate 131 , and the other end can also be directly fixed to the mounting cross plate 132 or the tank shell 114 .

[0069] When the portable viscosity measuring device 100 includes a locking mechanism 140, when the measuring column 120 needs to be switched from a vertical upright state to a horizontal placement state, the flip push plate 131 overcomes the elastic force provided by the upright elastic member to drive the locking seat 142 to move toward the locking member 141 until the measuring column 120 is completely placed horizontally in the groove 112. The locking portion 1411 and the locking matching portion 1421 cooperate with each other to achieve the locking of the locking member 141 and the locking seat 142 to lock the flip push plate 131. The position of the flip push plate 131 is locked; when the measuring column 120 needs to be switched from a horizontal placement state to a vertical upright state, the staff can gently press the detection end 122, so that the locking member 141 moves up and down with the elastic deformation of the bottom of the groove shell 114, thereby causing the locking portion 1411 to disengage from the locking mating portion 1421. At this time, the flip push plate 131 moves toward the direction of the mounting horizontal plate 132 under the elastic force provided by the upright elastic member, thereby causing the measuring column 120 to automatically flip outward.

[0070] Please refer again Figures 1 to 3In some embodiments, a tool storage slot 117 is formed on the operating surface 111. Specifically, when the frame 110 includes the panel 113 and the tank shell 114, the frame 110 also includes a hollow cylindrical structure 118 with one end open. The cylindrical structure 118 is fixed to the side of the panel 113 facing away from the operating surface 111. The operating surface 111 begins with a receiving and placing opening 1132 connected to the cylindrical structure 118. Of course, when the frame 110 is a solid structure, the tool storage slot 117 is a slot formed by machining or integral molding.

[0071] The tool storage slot 117 is used to store some small tools that may be used in viscosity measurement, such as a spoon for scooping the liquid to be tested, a rag for cleaning the detector, cleaning tools such as cleaning gas cylinders, etc., so as to further improve the convenience of on-site rapid testing.

[0072] Please refer again Figure 1 Furthermore, in some embodiments, the portable viscosity measuring device 100 further includes a cover 150. The cover 150 detachably covers the opening of the tool storage slot 117 to seal the tool storage slot 117. The provision of the cover 150 not only prevents small tools in the tool storage slot 117 from falling out during movement of the portable viscosity measuring device 100, but also provides a dust-proof function. Therefore, the provision of the cover 150 can protect the small tools in the tool storage slot 117.
