Description

Technical Field

[0001] The present application belongs to the technical field of detection devices, and in particular relates to a sensor. Background Art

[0002] In the fields of semiconductors, pharmaceuticals, refined chemical processing, vacuum coating, etc., there are usually requirements for high-precision and integrated control of fluids. In such scenarios, there are usually high requirements for fluid pressure control. Among them, fluid pressure control is very important, and pressure sensors that monitor fluid pressure are also indispensable components.

[0003] Currently, reference Figure 1 The fluid pipeline systems in these scenarios are typically complex, requiring pressure sensors to monitor fluid pressure in each section. In addition to transmitting the detected pressure parameters to the control system, the pressure sensors also need to display them on their own screens for easy user observation. During commissioning, production, and maintenance of the fluid pipeline system, users need to observe the data displayed by the sensors to determine if there are any anomalies in the fluid pipeline system.

[0004] Specifically, the pressure sensor is installed in the pipeline. In current pressure sensors, the display is typically bolted to the base. The display's orientation relative to the base is fixed and cannot be adjusted. Furthermore, the base has distinct inlet and outlet ports, which are not arranged symmetrically relative to the sensor's geometric center. This means that if the gas flow direction is fixed, the pressure sensor's mounting orientation is also fixed.

[0005] Because fluid pipeline systems are usually complex, the orientation of the pipelines and the flow direction of the fluid often vary, resulting in different orientations of the display screens of the sensors on each section of the pipeline. Especially in limited space and complex pipeline management systems, the different orientations of the display screens of each sensor greatly increase the difficulty for users to observe and read data, and also increase the time users spend reading and recording data, resulting in low efficiency. Utility Model Content

[0006] In view of the above problems, the present application provides a sensor that can alleviate the problem that different orientations of the sensor's display screen have a negative impact on engineers' observation of the display screen and reading of data.

[0007] An embodiment of the present application provides a sensor, including: a base, in which a detection component is provided; a rotating member, rotatably connected to the base; a display screen, provided on the rotating member and capable of rotating synchronously with the rotating member, the display screen being communicatively connected to the detection component; an adjusting member, slidably connected to the base along a first direction, the adjusting member being sleeved outside the rotating member; a pressing member, provided between the rotating member and the adjusting member, the pressing member being movably connected to the base along a second direction, the second direction being arranged to intersect with the first direction; wherein the movement of the adjusting member along the first direction can change the pressure between the pressing member and the rotating member.

[0008] In the technical solution of this embodiment, the display screen is set on the rotating member, and the rotating member is able to rotate relative to the base, so that the orientation of the display screen is adjustable, thereby facilitating the user to adjust the angle of the display screen as needed, so that the orientation of the display screen is convenient for the user to observe; an adjusting member is provided, and a holding member is provided between the adjusting member and the rotating member, so that the pressure of the holding member on the rotating member can be changed by changing the position of the adjusting member, thereby realizing the locking and release of the rotating member, so that the display screen can be fixed at a certain angle and the angle can be adjusted according to the needs of the user.

[0009] In some embodiments, the adjusting member has at least a first position and a second position, and the first position and the second position are arranged sequentially along the first direction toward the base; the adjusting member can move from the first position to the second position to provide decreasing pressure to the holding member.

[0013] In some embodiments, a first limiting portion is further provided on the side of the adjusting member facing the rotating member, and the first limiting portion is located on the side of the supporting portion away from the base.

[0014] In the technical solution of this embodiment, a first limit portion is provided on the adjusting member to limit the position of the adjusting member and to limit the position of the pressing member between the adjusting member and the rotating member, so as to prevent the position change of the pressing member from causing the fixing effect of the pressing member on the rotating member to fail; an accommodating space is provided, and when the pressing member is opposite to the accommodating space and partially enters the accommodating space, the pressing member can be separated from the rotating member or there is no pressure between the pressing member and the rotating member, so that the user can rotate the rotating member and adjust the orientation of the display screen.

[0015] In some embodiments, a second limiting portion is protruded on the peripheral side wall of the rotating member, and the second limiting portion is located on the side of the adjusting member away from the base along the first direction; in the first direction, an elastic member is provided between the adjusting member and the base, and the elastic member is used to apply a force to the adjusting member pointing in the direction of the second limiting portion so that the adjusting member can be supported against the second limiting portion.

[0016] In the technical solution of this embodiment, an elastic member is provided so as to realize the resetting of the adjusting member through the elastic member; at the same time, under the action of the second limiting portion and the elastic member, the adjusting member can be in a certain position without being affected by external force, and can apply pressure to the holding member at this position so that the holding member can press on the rotating member, thereby playing the role of fixing the rotating member.

At this time, the positioning member can fix the position of the adjusting member through the first positioning groove without maintaining external force, thereby reducing the difficulty of operation.

[0019] In some embodiments, at least two second positioning grooves are provided on the peripheral side of the rotating member; the rotation of the rotating member relative to the base can cause part of the pressing member to be accommodated in the second positioning grooves or to abut against the peripheral side wall of the rotating member.

[0020] In the technical solution of this embodiment, a second positioning groove is provided on the peripheral side of the rotating part so that part of the pressing part can enter the second positioning groove; after the part of the pressing part enters the second positioning groove, it is limited by the side wall of the second positioning groove, and the rotating part is difficult to rotate, thereby achieving the effect of fixing the position of the rotating part.

When the pressing member is not located in the second positioning groove, the pressing member can abut against the friction portion, so that the pressing member can also fix the position of the rotating member by abutting against the friction portion, thereby realizing stepless adjustment and fixation of the position of the rotating member.

[0023] In some embodiments, the sensor also includes a limit member; the limit member is arranged on the rotating member, and a partial circumferential long groove surrounding the rotating member is opened on the base, and a portion of the limit member is accommodated in the long groove; or the limit member is arranged on the base, and a partial circumferential long groove surrounding the rotating member is opened on the rotating member, and a portion of the limit member is accommodated in the long groove.

[0058] In the fields of semiconductors, pharmaceuticals, refined chemical processing, vacuum coating, etc., there are usually requirements for high-precision and integrated control of fluids. In such scenarios, there are usually high requirements for fluid pressure control. Among them, fluid pressure control is very important, and pressure sensors that monitor fluid pressure are also indispensable components.

[0059] Currently, reference Figure 1 The fluid pipeline systems in these scenarios are typically complex, requiring pressure sensors to monitor fluid pressure in each section. In addition to transmitting the detected pressure parameters to the control system, the pressure sensors also need to display them on their own screens for easy user observation. During commissioning, production, and maintenance of the fluid pipeline system, users need to observe the data displayed by the sensors to determine if there are any anomalies in the fluid pipeline system.

[0060] Specifically, the pressure sensor is installed in the pipeline. In current pressure sensors, the display is typically bolted to the base. The display's orientation relative to the base is fixed and cannot be adjusted. Furthermore, the base has distinct inlet and outlet ports, which are not arranged symmetrically relative to the sensor's geometric center. This means that if the gas flow direction is fixed, the pressure sensor's mounting orientation is also fixed.

[0061] Because fluid pipeline systems are usually complex, the orientation of the pipelines and the flow direction of the fluid often vary, resulting in different orientations of the display screens of the sensors on each section of the pipeline. Especially in limited space and complex pipeline management systems, the different orientations of the display screens of each sensor greatly increase the difficulty for users to observe and read data, and also increase the time users spend reading and recording data, resulting in low efficiency.

[0062] In view of the above problems, in order to alleviate the problem that the different orientations of the sensor's display screen have a negative impact on engineers' observation of the display screen and reading of data, an embodiment of the present application provides a sensor, wherein the display screen is set on a rotating part, and the rotating part can be rotated relative to the base, so that the orientation of the display screen is adjustable, thereby facilitating the user to adjust the angle of the display screen as needed, so that the orientation of the display screen can be convenient for the user to observe; an adjusting part is provided, and a pressing part is provided between the adjusting part and the rotating part, so that the pressure of the pressing part on the rotating part can be changed by changing the position of the adjusting part, thereby realizing locking and releasing of the rotating part, so that the display screen can be fixed at a certain angle and the angle can be adjusted according to the needs of the user.

[0063] The detection components in the sensors disclosed in the embodiments of the present application may include pressure detection devices, mass flow detection devices, liquid level detection devices, or other detection devices. The sensors may be, but are not limited to, pressure sensors, mass flow meters, liquid level sensors, and the like.

[0064] For the convenience of description, the following embodiments are described by taking the sensor 100 in some embodiments of the present application as a pressure sensor as an example.

[0065] refer to Figures 2 to 4 Some embodiments of the present application provide a sensor 100, comprising a base 10, a rotating member 30, a display screen 40, an adjustment member 50, and a pressing member 60. Specifically, a detection assembly 20 is disposed within the base 10; the rotating member 30 is rotatably connected to the base 10; the display screen 40 is disposed on the rotating member 30 and can rotate synchronously with the rotating member 30, and the display screen 40 is communicatively connected to the detection assembly 20; the adjustment member 50 is slidably connected to the base 10 along a first direction, and is sleeved outside the rotating member 30; the pressing member 60 is disposed between the rotating member 30 and the adjustment member 50, and is movably connected to the base 10 along a second direction, which intersects the first direction; and the movement of the adjustment member 50 along the first direction can change the pressure between the pressing member 60 and the rotating member 30.

[0066] The base 10 refers to a structure in the sensor 100 that provides a fixed foundation for the rotating part 30, the adjusting part 50 or other structures; the shape of the base 10 can be prismatic, cylindrical or other shapes; the material of the base 10 can include metal, plastic or other materials.

[0067] In a gas pipeline system, the base 10 is also used to be connected to the pipeline system.

[0068] The detection component 20 refers to the structure in the sensor 100 for detecting corresponding physical quantities or chemical quantities. The detection component 20 may include a pressure detection device, a mass flow detection device, a liquid level detection device or other detection devices to detect pressure, mass flow, liquid level and other data.

[0069] The rotating part 30 refers to a structure in the sensor 100 that can rotate relative to the base 10; the rotating part 30 can rotate 360° relative to the base 10, or can rotate 180°, 270° or other angles relative to the base 10; the shape of the rotating part 30 can be a solid cylindrical structure, a hollow cylindrical structure or a structure of other shapes; the material of the rotating part 30 can include metal, plastic or other materials.

[0070] It can be understood that the rotating member 30 can only rotate relative to the base 10 and is difficult to translate relative to the base 10 .

[0071] The display screen 40 refers to a structure in the sensor 100 for displaying the detection data of the detection component 20. The display screen 40 may include an LED display screen, an LCD display screen or other display screens. The display screen 40 is disposed on the rotating member 30. The display screen 40 may be fixedly connected to the rotating member 30 by bonding, welding or other means, or may be detachably connected to the rotating member 30 by screwing, snapping or other means. The rotation of the rotating member 30 relative to the base 10 can drive the display screen 40 to rotate synchronously, thereby changing the angle of the display screen 40.

[0072] The display screen 40 is communicatively connected to the detection component 20 so that the detection component 20 can send the real-time detection signal detected by it to the display screen 40, and the display screen 40 can display the real-time detection data it receives for the user to observe.

[0073] The display screen 40 can rotate synchronously with the rotating member 30 , so that the image on the display screen 40 can also rotate synchronously with the rotating member 30 , so that the user can adjust the direction of the image on the display screen 40 by rotating the rotating member 30 as needed.

[0074] The adjusting member 50 refers to a structure in the sensor 100 that can slide relative to the base 10. The adjusting member 50 is also sleeved outside the rotating member 30, that is, the adjusting member 50 is a cylindrical structure; the material of the adjusting member 50 can include metal, plastic or other materials.

[0075] The adjusting member 50 can slide relative to the base 10 in the first direction. Because the adjusting member 50 is disposed outside the rotating member 30, the rotating member 30 can also function to limit the displacement of the adjusting member 50. Accordingly, a guide structure can be provided on the base 10 to limit the displacement of the adjusting member 50, allowing the adjusting member 50 to move relative to the base 10 in the first direction. Alternatively, the guide structure can be omitted, and the displacement of the adjusting member 50 can be limited solely by the rotating member 30.

[0076] The first direction refers to the moving direction of the adjusting member 50 relative to the base 10. The first direction is a set direction, which can be parallel to the height direction and length direction of the sensor 100, or other directions; for example, when the base 10 is a cylindrical structure, the first direction is parallel to the axial direction of the base 10.

[0077] The pressing member 60 refers to a structure in the sensor 100 for fixing the rotating member 30 ; the shape of the pressing member 60 may be spherical, cylindrical, prismatic or other shapes; the material of the pressing member 60 may include metal, plastic or other materials.

[0078] The pressing member 60 is located between the rotating member 30 and the adjusting member 50, and the pressing member 60 is movably connected to the base 10, that is, the base 10 can also be used to provide an installation basis for the pressing member 60; for example, a structure for supporting the pressing member 60 can be provided on the base 10, and the pressing member 60 is movably provided on the structure so that the pressing member 60 can be movable relative to the base 10.

[0079] The pressing member 60 can move along the second direction, and the second direction is arranged to intersect with the first direction, that is, the second direction is not parallel to the first direction, that is, the pressing member 60 cannot move along the first direction; the second direction can be perpendicular to the first direction, and can also be arranged at other angles to the first direction; the pressing member 60 can increase or decrease the pressure between the rotating member 30 and the rotating member 30 when it moves along the second direction, so as to increase or decrease the rotational resistance of the rotating member 30; for example, the second direction is perpendicular to the first direction, and when the base 10 is a cylindrical structure, the second direction is parallel to the radial direction of the base 10.

[0080] The movement of the adjusting member 50 along the first direction can change the pressure between the pressing member 60 and the rotating member 30. When the pressure between the pressing member 60 and the rotating member 30 is large, the friction between the pressing member 60 and the rotating member 30 is also large. At this time, the pressing member 60 can fix the rotating member 30 through the friction, thereby achieving the effect of fixing the angle of the display screen 40; when the pressure between the pressing member 60 and the rotating member 30 is small, the friction between the pressing member 60 and the rotating member 30 is also small, so as to facilitate the rotation of the rotating member 30 and adjust the angle of the display screen 40.

[0081] It can be understood that in addition to providing a mounting base for the pressing member 60, the base 10 can also limit the position of the pressing member 60 in the first direction to avoid the pressing member 60 moving along the first direction due to the movement of the adjusting member 50, so that the adjusting member 50 can better change the pressure between the pressing member 60 and the rotating member 30 when it moves along the first direction.

[0082] For example, the first direction is the height direction of the sensor 100, and the upward movement of the adjusting member 50 can increase the pressure between the holding member 60 and the rotating member 30. At this time, the inner wall of the adjusting member 50 can be a structure that gradually expands upward along the first direction, that is, the inner diameter of the adjusting member 50 becomes smaller and smaller from top to bottom; as the adjusting member 50 moves upward along the first direction, the distance between the inner wall of the adjusting member 50 and the outer wall of the rotating member 30 will gradually decrease at the height of the holding member 60, and the adjusting member 50 pushes the holding member 60 to move in the direction of the rotating member 30 and abuts against the rotating member 30. As the adjusting member 50 continues to move, the friction between the holding member 60 and the rotating member 30 increases, and the resistance to the rotation of the rotating member 30 increases, so as to achieve The effect of fixing the rotating member 30 is achieved. At this time, the angle of the display screen 40 is relatively fixed and difficult to adjust; as the adjusting member 50 moves downward along the first direction, the distance between the inner wall of the adjusting member 50 and the outer wall of the rotating member 30 will gradually increase at the height of the pressing member 60, and the friction between the pressing member 60 and the rotating member 30 will decrease. As the adjusting member 50 continues to move, the pressing member 60 may also separate from the rotating member 30, and the resistance to the rotation of the rotating member 30 is reduced. At this time, the rotating member 30 can be rotated more easily, so that the user can adjust the angle of the display screen 40.

[0083] It is understandable that the exterior of the rotating member 30 may also be gradually expanded or contracted, and is not limited to the above structure.

[0084] It is understandable that other structures may be provided on the inner wall of the adjusting member 50 or the outer wall of the rotating member 30 so that the pressure between the pressing member 60 and the rotating member 30 can be changed when the adjusting member 50 moves in the first direction.

[0085] In this embodiment, the display screen 40 is set on the rotating member 30, and the rotating member 30 can rotate relative to the base 10, so that the orientation of the display screen 40 is adjustable, thereby facilitating the user to adjust the angle of the display screen 40 as needed, so that the orientation of the display screen 40 can be convenient for the user to observe; an adjusting member 50 is provided, and a holding member 60 is provided between the adjusting member 50 and the rotating member 30, so that the pressure of the holding member 60 on the rotating member 30 can be changed by changing the position of the adjusting member 50, thereby realizing the locking and release of the rotating member 30, so that the display screen 40 can be fixed at a certain angle and the angle can be adjusted according to the needs of the user.

[0086] refer to Figures 2 to 6 In some embodiments, the adjusting member 50 has at least a first position and a second position, and the first position and the second position are arranged sequentially along the first direction toward the base 10; the adjusting member 50 can move from the first position to the second position to provide decreasing pressure to the holding member 60.

[0087] The first position and the second position refer to positions to which the adjusting member 50 can move along the first direction; in addition to the first position and the second position, the adjusting member 50 can also move to other positions.

[0088] In the direction along the first direction toward the base 10, the first position and the second position are arranged in sequence, that is, when the adjusting member 50 moves toward the direction close to the base 10, the adjusting member 50 can be located at the first position first and then at the second position; taking the first direction parallel to the height direction of the sensor 100 as an example, the second position is located between the first position and the base 10.

[0089] When the adjusting member 50 moves toward the direction closer to the base 10, the adjusting member 50 can move from the first position to the second position; in this process, the pressure provided by the adjusting member 50 to the pressing member 60 decreases, so that the pressure between the pressing member 60 and the rotating member 30 also decreases, the friction between the pressing member 60 and the rotating member 30 decreases, and the resistance to the rotation of the rotating member 30 decreases.

[0090] On the contrary, when the adjusting member 50 moves in a direction away from the base 10, the adjusting member 50 can move from the second position to the first position; in this process, the pressure provided by the adjusting member 50 to the holding member 60 increases, so that the pressure between the holding member 60 and the rotating member 30 also increases, the friction between the holding member 60 and the rotating member 30 increases, and the resistance to the rotation of the rotating member 30 increases.

[0091] For example, the first position may be the position where the adjusting member 50 is farthest from the base 10, and the second position may be the position where the adjusting member 50 is closest to the base 10; at this time, when the adjusting member 50 is in the first position, the pressure between the pressing member 60 and the rotating member 30 is the largest, and when the adjusting member 50 is in the second position, the pressure between the pressing member 60 and the rotating member 30 is the smallest.

[0092] In this embodiment, the adjusting member 50 has different positions and is able to provide different pressures to the holding member 60 at different positions, so that the user can rotate and fix the rotating member 30 by changing the position of the adjusting member 50, thereby facilitating adjustment or fixing the angle of the display screen 40.

[0093] refer to Figures 4 to 6 、 Figure 8In some embodiments, a supporting portion 51 is provided on the side of the adjusting member 50 facing the rotating member 30, and the supporting portion 51 is supported by the pressing member 60; a slope 511 is provided on the side of the supporting portion 51 facing the rotating member 30, and the distance between the slope 511 and the rotating member 30 gradually increases in the direction away from the base 10 along the first direction.

[0094] The supporting portion 51 refers to a structure located on the side of the adjusting member 50 facing the rotating member 30. The supporting portion 51 protrudes from the adjusting member 50. The supporting portion 51 can be a part of the adjusting member 50 and be integrally formed with the adjusting member 50. The supporting portion 51 can also be an independent component and be connected to the adjusting member 50 by welding, bonding or other means; the material of the supporting portion 51 can include metal, plastic or other materials.

[0095] The supporting portion 51 is supported against the pressing member 60, that is, the supporting portion 51 and the pressing member 60 are located at the same height, and the supporting portion 51 is used to provide pressure to the pressing member 60 to press the pressing member 60 against the rotating member 30; it can be understood that during the displacement of the adjusting member 50 along the first direction, the supporting portion 51 can always be supported against the pressing member 60.

[0096] A slope 511 is provided on the side of the supporting portion 51 facing the rotating member 30. The slope 511 refers to a surface inclined relative to the first direction. The setting of the slope 511 can enable the distance between the supporting portion 51 and the outer wall of the rotating member 30 to change along the first direction, so that the adjustment member 50 can change the pressure on the holding member 60 when it moves along the first direction.

[0097] In the direction away from the base 10 along the first direction, the distance between the inclined surface 511 and the rotating member 30 gradually increases; at this time, the adjustment member 50 moves toward the base 10 along the first direction to increase the distance between the inclined surface 511 and the outer wall of the rotating member 30, so as to reduce the pressure of the inclined surface 511 on the holding member 60, thereby reducing the pressure of the inclined surface 511 on the rotating member 30 and reducing the rotational resistance of the rotating member 30, so as to facilitate adjustment of the angle of the rotating member 30; the adjustment member 50 moves away from the base 10 along the first direction to reduce the distance between the inclined surface 511 and the outer wall of the rotating member 30, so as to increase the pressure of the inclined surface 511 on the holding member 60, thereby increasing the pressure of the inclined surface 511 on the rotating member 30 and increasing the rotational resistance of the rotating member 30, thereby achieving the effect of fixing the rotating member 30.

[0098] It is understandable that friction lines may be provided on the outer wall of the rotating member 30 , sandblasting may be performed, or other methods may be used to increase the friction of the outer wall of the rotating member 30 so that the pressing member 60 can better fix the rotating member 30 .

[0099] This embodiment provides some specific structures of the adjusting member 50 so that the adjusting member 50 can provide different pressures to the pressing member 60 at different positions.

[0100] refer to Figures 4 to 6 、 Figure 8 In some embodiments, a first limiting portion 52 is further provided on the side of the adjusting member 50 facing the rotating member 30. The first limiting portion 52 is located on the side of the supporting portion 51 away from the base 10 along the first direction. The adjusting member 50 can be supported by the pressing member 60 when moving along the first direction; an accommodating space 55 is provided between the first limiting portion 52 and the first limiting portion 52. The accommodating space 55 is used to accommodate part of the pressing member 60 to reduce the pressure between the pressing member 60 and the rotating member 30.

[0101] The first limiting portion 52 refers to a structure located on the side of the adjusting member 50 facing the rotating member 30. The first limiting portion 52 protrudes from the adjusting member 50. The first limiting portion 52 can be a part of the adjusting member 50 and be integrally formed with the adjusting member 50. The first limiting portion 52 can also be an independent component and be connected to the adjusting member 50 by welding, bonding or other means; the material of the first limiting portion 52 can include metal, plastic or other materials.

[0102] The first limiting portion 52 is located on the side of the supporting portion 51 away from the base 10 along the first direction. When the adjusting member 50 moves toward the direction close to the base 10, the first limiting portion 52 can be supported by the pressing member 60, making it difficult for the first limiting portion 52 to move further.

[0103] For example, taking the first direction as the height direction parallel to the sensor 100 as an example, when the adjusting member 50 moves downward along the first direction, the distance between the inclined surface 511 of the supporting portion 51 and the outer wall of the rotating member 30 increases at the height where the pressing member 60 is located, the pressure of the supporting portion 51 on the pressing member 60 decreases, and the pressure of the pressing member 60 on the rotating member 30 also decreases; when the adjusting member 50 moves to the lowermost position, the first limiting portion 52 abuts against the pressing member 60, and the adjusting member 50 is difficult to move further, thereby making it difficult for the adjusting member 50 to separate from the pressing member 60.

[0104] An accommodating space 55 is further provided between the first limiting portion 52 and the supporting portion 51. The accommodating space 55 is used to accommodate part of the pressing member 60. When the adjusting member 50 moves toward the base 10 and the first limiting portion 52 is supported on the pressing member 60, the pressing member 60 is opposite to the accommodating space 55, and part of the pressing member 60 enters the accommodating space 55. At this time, the pressing member 60 is separated from the supporting portion 51, and the pressure of the adjusting member 50 on the pressing member 60 is minimal. The pressing member 60 is separated from the rotating member 30 or there is no pressure between the pressing member 60 and the rotating member 30, so as to reduce the resistance to the rotation of the rotating member 30, thereby facilitating the user to rotate the rotating member 30 and adjust the orientation of the display screen 40.

[0105] In this embodiment, a first limiting portion 52 is provided on the adjusting member 50 to limit the position of the adjusting member 50 and to limit the position of the pressing member 60 between the adjusting member 50 and the rotating member 30, so as to prevent the position change of the pressing member 60 from causing the fixing effect of the pressing member 60 on the rotating member 30 to fail; an accommodating space 55 is provided, and when the pressing member 60 is opposite to the accommodating space 55 and partially enters the accommodating space 55, the pressing member 60 can be separated from the rotating member 30 or there is no pressure between the pressing member 60 and the rotating member 30, so that the user can rotate the rotating member 30 and adjust the orientation of the display screen 40.

[0106] refer to Figures 4 to 7 In some embodiments, a second limiting portion 31 is protruded from the peripheral side wall of the rotating member 30, and the second limiting portion 31 is located on the side of the adjusting member 50 away from the base 10 along the first direction; in the first direction, an elastic member 70 is provided between the adjusting member 50 and the base 10, and the elastic member 70 is used to apply a force to the adjusting member 50 pointing in the direction of the second limiting portion 31, so that the adjusting member 50 can be supported against the second limiting portion 31.

[0107] The second limiting portion 31 refers to a structure located on the rotating member 30. The second limiting portion 31 protrudes from the rotating member 30. The second limiting portion 31 can be a part of the rotating member 30 and be integrally formed with the rotating member 30. The second limiting portion 31 can also be an independent component and be connected to the rotating member 30 by welding, bonding or other means; the material of the second limiting portion 31 can include metal, plastic or other materials.

[0108] The second limiting portion 31 is located on the side of the adjusting member 50 away from the base 10, and the second limiting portion 31 is used to limit the displacement of the adjusting member 50; when the adjusting member 50 moves in a direction away from the base 10, the adjusting member 50 can be supported by the second limiting portion 31, thereby making it difficult for the adjusting member 50 to move further.

[0109] For example, taking the first direction as the height direction parallel to the sensor 100 as an example, when the adjusting member 50 moves upward along the first direction, the distance between the inclined surface 511 of the supporting portion 51 and the outer wall of the rotating member 30 decreases at the height where the pressing member 60 is located, the pressure of the supporting portion 51 on the pressing member 60 increases, and the pressure of the pressing member 60 on the rotating member 30 also increases; when the adjusting member 50 moves to the uppermost position, the second limiting portion 31 is supported by the adjusting member 50, and the second limiting portion 31 is difficult to move further, so that the adjusting member 50 is difficult to separate from the pressing member 60.

[0110] The elastic member 70 refers to a structure in the sensor 100 for holding the adjusting member 50 against the second limiting portion 31. The elastic member 70 may be a spring, or an elastic rubber sleeve or other elastic structure. The elastic member 70 may apply a force to the adjusting member 50 in the direction of the second limiting portion 31. When the adjusting member 50 is not subjected to external force, the elastic member 70 may hold the adjusting member 50 against the second limiting portion 31, so that the adjusting member 50 is stably held against the second limiting portion 31 and is not easily displaced, thereby improving the stability of the entire structure.

[0111] Because the elastic member 70 is located between the base 10 and the adjusting member 50, and the second limiting portion 31 is located on the side of the adjusting member 50 away from the base 10, and because the elastic member 70 is used to apply pressure to the adjusting member 50 to hold the adjusting member 50 against the second limiting portion 31, the elastic member 70 can always be in a compressed state; when the adjusting member 50 is held against the second limiting portion 31, the elastic member 70 is in a compressed state to press the adjusting member 50 against the second limiting portion 31; when the adjusting member 50 moves toward the direction close to the base 10, the elastic member 70 is compressed and further compressed and deformed.

[0112] For example, the first direction is parallel to the height direction of the sensor 100. When the adjusting member 50 is abutted against the second limit portion 31, the adjusting member 50 is at the uppermost end. At this time, the distance between the inclined surface 511 of the abutting portion 51 and the outer wall of the rotating member 30 at the height of the pressing member 60 is the smallest. The pressure of the adjusting member 50 on the pressing member 60 is the greatest, and the greater the pressure of the pressing member 60 on the rotating member 30, the rotating member 30 is not easy to rotate and is relatively fixed. The angle of the display screen 40 is also relatively fixed, and the sensor 100 is in a stable state. At the same time, after the adjusting member 50 moves downward under the action of external force, if the external force disappears, the adjusting member 50 can also return to its original position under the action of the elastic member 70 and abut against the second limit member 80.

[0113] In this embodiment, an elastic member 70 is provided so that the adjusting member 50 can be reset by the elastic member 70; at the same time, under the action of the second limiting portion 31 and the elastic member 70, the adjusting member 50 can be in a certain position without being affected by external force, and can apply pressure to the holding member 60 at this position, so that the holding member 60 can be pressed on the rotating member 30, thereby playing the role of fixing the rotating member 30.

[0114] refer to Figures 4 to 6 、 Figure 8In some embodiments, a positioning member 11 is provided on the base 10 and is supported against the adjusting member 50. The positioning member 11 is an elastic structural member. A first positioning groove 53 is provided on the side of the adjusting member 50 facing the rotating member 30, and the first positioning groove 53 is located on the side of the adjusting member 50 close to the base 10. The first positioning groove 53 is used to accommodate the positioning member 11. The movement of the adjusting member 50 along the first direction can enable the positioning member 11 to enter or escape from the first positioning groove 53, and the positioning member 11 entering the first positioning groove 53 can fix the adjusting member 50.

[0115] The positioning member 11 refers to a structure used to fix the position of the adjusting member 50; the positioning member 11 can be an annular member mounted outside the base 10, or it can be a strip member, a columnar member or a member of other shapes; the positioning member 11 is an elastic structural member, that is, the material of the positioning member 11 can include rubber, or it can include other elastic materials such as elastic metal.

[0116] The first positioning groove 53 refers to a groove structure provided on the adjusting member 50, and the first positioning groove 53 is used to accommodate the positioning member 11; the cross-sectional shape of the first positioning groove 53 can be square, semicircular, trapezoidal or other shapes; the first positioning groove 53 can be an annular groove surrounding the inner wall of the adjusting member 50, or it can be a groove of other shapes. The shape of the first positioning groove 53 can also be set according to the shape of the positioning member 11.

[0117] The first positioning groove 53 is provided on the side of the adjusting member 50 facing the rotating member 30, and the first positioning groove 53 is located on the side of the adjusting member 50 close to the base 10; when the adjusting member 50 moves toward the direction close to the base 10 and moves to a certain position, the positioning member 11 enters the first positioning groove 53, and the positioning member 11 and the first positioning groove 53 cooperate to fix the adjusting member 50. At this time, the adjusting member 50 can be fixed without being subjected to external force, and at the same time, the user can pull the adjusting member 50 to make the positioning member 11 disengage from the first positioning groove 53.

[0118] For example, taking the first direction as the height direction parallel to the sensor 100 as an example, when the adjusting member 50 moves to the lowermost position, the positioning member 11 enters the first positioning groove 53. At this time, the adjusting member 50 can be fixed by the positioning member 11 without being subjected to external force. When an elastic member 70 is provided between the base 10 and the adjusting member 50, the cooperation between the positioning member 11 and the first positioning groove 53 can also overcome the restoring force of the elastic member 70 and fix the elastic member 70; after the adjusting member 50 is fixed by the positioning member 11, pulling the adjusting member 50 upward along the first direction can cause the positioning member 11 to disengage from the first positioning groove 53, and enable the adjusting member 50 to continue to move upward.

[0119] In this embodiment, a positioning member 11 is provided so that when the adjusting member 50 moves to a certain position, the positioning member 11 can enter the first positioning groove 53. At this time, the positioning member 11 can fix the position of the adjusting member 50 through the first positioning groove 53 without maintaining external force, thereby reducing the difficulty of operation.

[0120] It can be understood that the inclination direction of the inclined surface 511 can also be set in the opposite direction, that is, in the direction away from the base 10 along the first direction, the distance between the inclined surface 511 and the rotating member 30 gradually decreases; at this time, the first limiting portion 52 can be located on the side of the adjusting member 50 facing the base 10, that is, below the supporting portion 51; the elastic member 70 can be located on the side of the adjusting member 50 away from the base 10, that is, above the adjusting member 50, and accordingly, the second limiting portion 31 is also located below the adjusting member 50.

[0121] refer to Figures 4 to 7 In some embodiments, at least two second positioning grooves 32 are provided on the peripheral side of the rotating member 30; the rotation of the rotating member 30 relative to the base 10 can enable part of the holding member 60 to be accommodated in the second positioning groove 32 or to abut against the peripheral side wall of the rotating member 30.

[0122] The second positioning groove 32 refers to a groove structure arranged on the circumferential side of the rotating part 30, and the second positioning groove 32 is used to accommodate part of the holding part 60; the cross-sectional shape of the second positioning groove 32 can be square, semicircular, trapezoidal or other shapes; the number of the second positioning grooves 32 can be two, or three or more, and each second positioning groove 32 is arranged at intervals along the circumference of the rotating part 30.

[0123] Part of the pressing member 60 can enter the second positioning groove 32. At this time, the rotating member 30 is difficult to rotate due to the restriction of the inner wall of the second positioning groove 32 and the pressing member 60; the pressing member 60 can also be pressed against the peripheral side wall of the rotating member 30. When the pressure between the pressing member 60 and the peripheral side wall of the rotating member 30 is large, the rotating member 30 is also not easy to rotate.

[0124] For example, the intersection of the inner wall of the second positioning groove 32 and the peripheral side wall of the rotating member 30 may be provided with a rounded corner to facilitate the pressing member 60 to enter or exit the second positioning groove 32 .

[0125] For example, the first direction is parallel to the height direction of the sensor 100. When the adjusting member 50 is at the lowermost end, the pressure exerted by the adjusting member 50 on the pressing member 60 is minimal, and the pressure exerted by the pressing member 60 on the rotating member 30 is also minimal. At this time, the rotating member 30 can rotate; after the rotation angle of the rotating member 30 is determined, the second positioning groove 32 can be opposite to the pressing member 60. At this time, the upward movement of the adjusting member 50 can press part of the pressing member 60 into the second positioning groove 32, thereby fixing the rotating member 30; after the rotation angle of the rotating member 30 is determined, the second positioning groove 32 can also be staggered with the pressing member 60. At this time, the upward movement of the adjusting member 50 can press the pressing member 60 on the peripheral side wall of the rotating member 30 to fix the rotating member 30 by friction.

[0126] In this embodiment, a second positioning groove 32 is provided on the peripheral side of the rotating member 30 so that a portion of the pressing member 60 can enter the second positioning groove 32; after the portion of the pressing member 60 enters the second positioning groove 32, the rotating member 30 is limited by the side wall of the second positioning groove 32, and it is difficult for the rotating member 30 to rotate, thereby achieving the effect of fixing the position of the rotating member 30.

[0127] refer to Figures 4 to 7 In some embodiments, a friction portion 33 is further provided on the circumferential side of the rotating member 30, and the friction portion 33 and the second positioning groove 32 are arranged alternately in sequence; the rotation of the rotating member 30 relative to the base 10 can enable part of the pressing member 60 to be accommodated in the second positioning groove 32 or to abut against the friction portion 33 of the rotating member 30.

[0128] The friction portion 33 is arranged between two adjacent second positioning grooves 32, and the friction portion 33 is used to increase the friction force between the holding part 60 and the rotating part 30; the friction portion 33 can be a part of the circumferential side wall of the rotating part 30 that has been sprayed with stars, and the friction portion 33 can also be formed by setting friction lines on the part of the circumferential side wall of the rotating part 30. The friction portion 33 can also be formed by other methods or structures.

[0129] After the rotating part 30 rotates, the pressing part 60 can be opposite to the second positioning groove 32 or the friction part 33; when the pressing part 60 is opposite to the friction part 33, there can be a larger friction force between the pressing part 60 and the friction part 33, so that the pressing part can better fix the rotating part 30 through the friction force.

[0130] For example, the first direction is parallel to the height direction of the sensor 100. When the adjusting member 50 is at the lowermost end, the pressure exerted by the adjusting member 50 on the pressing member 60 is minimal, and the pressure exerted by the pressing member 60 on the rotating member 30 is also minimal. At this time, the rotating member 30 can rotate. After the rotation angle of the rotating member 30 is determined, the pressing member 60 can be opposite to the friction portion 33. At this time, the upward movement of the adjusting member 50 can cause the pressing member 60 to be pressed on the friction portion 33, so as to fix the rotating member 30 by friction. After the rotation angle of the rotating member 30 is determined, the pressing member 60 can also be opposite to the second positioning groove 32. At this time, the upward movement of the adjusting member 50 can press part of the pressing member 60 in the second positioning groove 32, thereby fixing the rotating member 30.

[0131] In this embodiment, a friction portion 33 is provided between two adjacent second positioning grooves 32. When the pressing member 60 is not located in the second positioning groove 32, the pressing member 60 can abut against the friction portion 33, so that the pressing member 60 can also fix the position of the rotating member 30 by abutting against the friction portion 33, thereby realizing stepless adjustment and fixation of the position of the rotating member 30.

[0132] refer to Figures 4 to 10 In some embodiments, the sensor 100 further includes a limit member 80; the limit member 80 is provided on the rotating member 30, and a partial circumferential long groove 12 surrounding the rotating member 30 is opened on the base 10, and a portion of the limit member 80 is accommodated in the long groove 12; or the limit member 80 is provided on the base 10, and a partial circumferential long groove 12 surrounding the rotating member 30 is opened on the rotating member 30, and a portion of the limit member 80 is accommodated in the long groove 12.

[0134] The limiting member 80 can be provided on the rotating member 30. In this case, a long groove 12 can be provided on the base 10. Part of the limiting member 80 can extend into the long groove 12. The side wall of the long groove 12 can limit the rotation angle of the rotating member 30 through the limiting member 80, and can also limit the displacement of the rotating member 30; for example, the limiting member 80 can be abutted against the side wall of the long groove 12 in the first direction to limit the displacement of the rotating member 30 in the first direction, so that the rotating member 30 can only rotate relative to the base 10, and it is difficult to move along the first direction relative to the base 101.

[0135] The long groove 12 is a groove structure surrounding part of the circumference of the base 10. The surrounding angle of the long groove 12 can be 270°, or 230°, 250°, 280° or other angles; the long groove 12 can pass through the base 10 or not.

[0136] The limiting member 80 may also be provided on the base 10. In this case, the rotating member 30 may be provided with an elongated slot 12, and a portion of the limiting member 80 may extend into the elongated slot 12. The limiting member 80 can limit both the rotation angle and the displacement of the rotating member 30 via the sidewalls of the elongated slot 12. The elongated slot 12 is a groove structure that surrounds a portion of the circumference of the rotating member 30. The surrounding angle of the elongated slot 12 can be 270°, 230°, 250°, 280°, or other angles. The elongated slot 12 may or may not extend through the rotating member 30.

[0137] For example, the first direction is parallel to the height direction of the sensor 100, the long groove 12 is set as an annular groove surrounding the base 10270°, the limit member 80 is provided on the rotating member 30, and part of the limit member 80 extends into the annular groove; the rotation axis of the rotating member 30 is parallel to the height direction of the sensor 100, and the rotating member 30 can rotate 270°. At the same time, restricted by the side wall of the long groove 12 in the height direction of the sensor 100, the rotating member 30 is difficult to move along the height direction of the sensor 100, thereby making it difficult for the rotating member 30 to separate from the base 10.

[0138] In this embodiment, a long groove 12 is provided on one of the rotating member 30 or the base 10, and a limiting member 80 partially located in the long groove 12 is provided on the other, so that the rotating member 30 is difficult to separate from the base 10; at the same time, the long groove 12 and the limiting member 80 can also limit the rotation angle of the rotating member 30 relative to the base 10, thereby reducing the damage, breakage, etc. that may occur to the connecting cable between the display screen 40 and the detection component 20 after a large angle rotation.

[0139] refer to Figures 4 to 6 、 Figure 10 、 Figure 11 In some embodiments, the base 10 includes a base 101 and a cylinder 102 connected to the base 101, the detection component 20 is connected to the base 101 and accommodated in the cylinder 102; at least a portion of the rotating member 30 is accommodated in the cylinder 102, the adjusting member 50 is sleeved on the cylinder 102, and the holding member 60 is passed through the cylinder 102.

[0140] The base 101 refers to the basic structure of the base 10, and the base 101 can be installed on a piping system or other structures; the base 101 can be prismatic, cylindrical or other shapes; the material of the base 101 can include metal, plastic or other materials.

[0141] The cylinder 102 refers to a structure in the base 10 used to provide a fixed foundation for structures such as the rotating part 30, the adjusting part 50, and the pressing part 60. The rotating part 30 can be a cylindrical structure and is located in the cylinder 102, that is, the cylinder 102 is sleeved outside the rotating part 30; the adjusting part 50 can be sleeved outside the cylinder 102 to indirectly sleeve outside the rotating part 30; the pressing part 60 can be passed through the cylinder 102, so that the two ends of the pressing part 60 can respectively abut against the adjusting part 50 and the rotating part 30, and at the same time, the pressing part 60 can be difficult to move in the first direction.

[0142] The detection assembly 20 may also be housed within the barrel 102 and located on the base 10. For example, the detection assembly 20 may include a sensitive element 21 and a control unit 22; the sensitive element 21 refers to an element in the detection assembly 20 that is used to directly sense the physical quantity being measured.
