Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of flow meters, and particularly relates to a rotation adjusting structure with paragraph feeling. BACKGROUND

[0002] In modern heating and water supply systems, flow meters, as indispensable devices for monitoring fluid flow, play a crucial role. Traditional flow meter designs often integrate control structures, enabling remote transmission of flow data to a central monitoring system, achieving real-time data collection and analysis. To improve the convenience of on-site operations, flow meters usually come equipped with display screens, aiming to directly show flow readings to operators for immediate monitoring and management.

[0003] However, in practical applications, this design faces a significant limitation: the standing position of the operator when taking readings often cannot align with the ideal viewing angle of the flow meter display screen, leading to difficulties in reading or misreading. Especially in complex and variable on-site environments, the standing position of the operator is flexible and variable, while the fixed orientation of the flow meter display screen limits its readability and user experience.

[0004] Therefore, while providing the convenience of remote data transmission, the existing flow meter fails to adequately address the inconvenience caused by viewing angle issues when directly reading on-site, which to some extent affects the operational efficiency and precision of maintenance and management of heating and water supply systems. In view of this, it is necessary to provide a new type of flow meter display solution to solve the problem of reading difficulty caused by mismatched viewing angles and improve the convenience and accuracy of on-site operations.

DETAILED DESCRIPTION

[0027] Hereinafter, the application will be further described based on the preferred embodiments and with reference to the drawings.

[0028] The words in the specification are used to illustrate the embodiments of the application, but are not intended to limit the application. Unless otherwise explicitly specified and limited, if the terms "provided", "connected", "connected" appear, they should be understood broadly, for example, they can be fixedly connected, or detachably connected, or integrally connected; they can be mechanically connected, or directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the application can be specifically understood.

[0029] In addition, in the description of the embodiments of the application, various components on the drawing are enlarged or reduced for the convenience of understanding, but this practice is not intended to limit the protection scope of the application.

[0030] ​The application provides a rotation adjusting structure 64 with paragraph sense, which is connected between a first mechanism and a second mechanism, the first mechanism is rotationally connected with the second mechanism in multiple stop positions through the rotation adjusting structure 64, for the convenience of describing the specific application scenario of the rotation adjusting structure 64, the first mechanism in the application is a display device 6, and the second mechanism is a shell 1 connected with the display device 6.

[0031] In the actual installation and use process of the existing flowmeter with the display device 6, there is a problem: although the user can intuitively observe the flow data through the display 61, the standing position of the observer is not fixed. If the display direction of the display 61 is fixed, only the user in a specific position can observe the forward and neat flow data, and the users in other positions may encounter the problem of inconvenient reading.

[0032] Based on the above problem, the application provides a rotation adjusting structure with paragraph sense, which is applied to the display device 6 of the flowmeter, Figure 3 The application shows the explosion view of the whole structure of the rotation adjusting structure applied to the flowmeter in the application, as shown in Figure 3 The flowmeter includes a shell 1, a fluid pipeline, an ultrasonic transceiver device, a control device, a power supply device 5 and a display device 6, the power supply device 5 provides power for the ultrasonic transceiver device, the control device and the display device 6, the control device is in communication connection with the ultrasonic transceiver device and the display device 6, the shell 1 is formed with a fluid pipeline for liquid flow and a space for installing the ultrasonic transceiver device, the display device 6 and the control device, the control device displays the data to be displayed through the display device 6, so that the user can intuitively obtain real-time data.

[0033] Further, as shown in Figure 3 The display device 6 is rotationally and flexibly connected with the shell 1 in multiple stop positions through the rotation adjusting structure 64, the display 61 is realized 360° rotation relative to the cross section of the shell 1, and the user can conveniently and timely adjust the display 61 to an angle convenient for reading.

[0034] Further, as shown in Figure 1 and Figure 2As shown, the rotation adjustment structure 64 is located between the display device 6 and the inner wall of the outer casing 1. It includes multiple circumferentially distributed adjustment slots 641 and elastic limiting parts 642. During the rotation of the display device 6 relative to the outer casing 1, it drives the adjustment slots 641 to rotate relative to the elastic limiting parts 642, or drives the elastic limiting parts 642 to rotate relative to the adjustment slots 641, so that the elastic limiting parts 642 rotate and move from one adjustment slot 641 to the next adjustment slot 641. When the elastic limiting part 642 rotates to one end of the adjustment slot 641 and enters the adjustment slot 641, the compressive force on the elastic limiting part 642 is minimal, and the elastic limiting part 642 is in a relatively or completely natural state. When rotation continues, the compressive force on the elastic limiting part 642 gradually increases, its length gradually decreases, and it gradually moves out of this adjustment slot 641. When rotation continues, the compressive force on the elastic limiting part 642 gradually decreases, its length gradually increases, and it gradually rotates to another adjustment slot 641. This achieves relative fixation of the elastic limiting part 642 within different adjusting grooves 641, ensuring a relatively stable connection of multiple stops while rotating, thus facilitating reading by users at different angles.

[0035] In some preferred embodiments of this application, the adjustment groove 641 is formed on the end face of the display device 6 facing the inside of the housing 1. This end face is a planar structure, and forming the adjustment groove 641 on this end face facilitates processing and eliminates the need for additional structures inside the housing 1 for forming the adjustment groove 641. It is conceivable that the adjustment groove 641 can also be formed on the end face of a structure inside the display device 6 facing away from the inside of the housing 1, with the elastic limiting part 642 abutting against the end face of that structure facing away from the inside of the housing 1.

[0036] In some specific embodiments of this application, the elastic limiting part 642 includes an elastic part 6421 and a second mating part 6422. The second mating part 6422 is connected to one end of the elastic part 6421 facing the adjustment groove 641. The second mating part 6422 elastically abuts against and engages with multiple adjustment grooves 641 through the elastic part 6421, so that the user feels a breakage during rotation and makes a clicking sound, which can gradually adjust the angle of the display 61 relative to the user.

[0037] It is conceivable that the elastic part 6421 can be an elastic element such as a spring, a clockwork, a hairspring, or a single diaphragm. Regardless of the type of elastic element used, it is acceptable as long as it has the ability to elastically deform while being connected to the second mating part 6422.

[0038] like Figure 2 As shown, in some specific embodiments of this application, the elastic part 6421 is a helical spring, which has the advantages of no need for lubrication, strong anti-fouling properties, small longitudinal space occupation, small weight, and low cost.

[0039] It is conceivable that the shape of the adjusting groove 641 can match or not match the shape of the second matching part 6422.

[0040] It is conceivable that the second matching part 6422 can be a regular shape such as a square or a sphere, or an irregular shape.

[0041] In some preferred embodiments of the present application, the second matching part 6422 is a spherical structure, and the adjusting groove 641 is a semispherical groove structure. During rotation, the extrusion force on the second matching part 6422 gradually changes during elastic abutment with the adjusting groove 641, avoiding vibration and instability caused by a sharp change in extrusion force, improving the stability, precision, and reliability of the structure, and reducing the risk of structural damage.

[0042] In some preferred embodiments of the present application, as shown in Figure 3 and Figure 4 to ensure the stability and consistency of the deformation direction of the elastic part 6421, the rotating adjusting structure 64 further includes a guide part 643, which is a closed-end cylinder structure with its closed end connected to the inner wall of the shell 1, and the elastic limiting part 642 is connected inside the guide part 643. The second matching part 6422 can reciprocally displace along the axial direction of the guide part 643 under the action of the extrusion force. The guide part 643 can significantly enhance the structural stability of the elastic limiting part 642, optimize the force transmission path, improve the dynamic performance, enhance the adaptability, and increase the service life.

[0043] Further, the display device 6 includes a display 61.

[0044] In some preferred embodiments of the present application, since there are many lines inside the flow meter, in order to ensure the clarity and neatness of the lines, as shown in Figure 5 the corresponding line boards at the display device 6 are subjected to layered processing, including first and second line boards 62 and 63 arranged in sequence, the display 61 is installed on the first line board 62, and only the lines connected to the display 61 are provided on the first line board 62, and other lines are connected to the second line board 63, avoiding the problem of line disorder caused by connecting all lines to the first line board 62.

[0045] In some specific embodiments of the present application, the second line board 63 has lines connected to the ultrasonic transceiver device. It is conceivable that in some other specific embodiments of the present application, the second line board 63 also has lines connected to the flow regulating valve and the temperature sensor.

[0046] It is conceivable that in order to realize the connection of the second line board 63 and the shell 1, the shell 1 can ensure the stability of the connection by means of one or more limiting structures, clamping structures, or the like.

[0047] In some specific embodiments of the present application, as shown in Figure 5 The shell 1 further comprises a first limiting structure 18 and a second limiting structure 19, both of which are connected to the inner wall of the shell 1 and located on the upper and lower sides of the second circuit board 63 to limit the second circuit board 63.

[0048] In some preferred embodiments of the present application, the side and bottom end of the second limiting structure 19 are provided with a certain gap with the adjacent structures, so as to provide a certain displacement space for the second limiting structure 19, improve the stability and durability of the structure, and facilitate installation and maintenance.

[0049] Further, the shell 1 further comprises a first matching part located at the bottom of the second limiting structure 19, the bottom end of which is connected to the inner wall of the shell 1, and a V-shaped groove is arranged on the top thereof to abut against the bottom of the second limiting structure 19. The first matching part ensures that the bottom of the second limiting structure 19 does not directly contact other structures except the first matching part, and ensures that the bottom end of the second limiting structure 19 does not completely contact other adjacent structures, leaving a certain displacement space. It can be imagined that the second limiting structure 19 can also be connected by arranging connecting or limiting structures on the shell 1 or other structures to ensure that the bottom end of the second limiting structure 19 leaves a certain gap with other adjacent structures.

[0050] In some specific embodiments of the present application, in order to realize the stable connection of the display device 6 and the shell 1, the display device 6 further comprises a mounting structure 65 matched with the cavity position structure of the shell 1 where the display device 6 is installed. The mounting structure 65 has a first circuit board 62 and a second circuit board 63 arranged in parallel installed therein, and the bottom end and the side thereof are sealed and connected to the inner wall of the shell 1 by a sealing structure, which ensures the stable connection with the shell 1 while maintaining the water-tight connection between the two. It should be particularly noted that the present application realizes the cooperation of the first circuit board 62, the second circuit board 63 and the mounting structure 65, so that only the lines connected with the display 61 are left on the first circuit board 62. When the user rotates the rotating adjusting structure 64 to adjust the angle of the display 61, the lines will not be tangled or knotted.

[0051] Further, as shown in Figure 1 and Figure 2 In some specific embodiments of the present application, the adjusting groove 641 is opened at one end of the mounting structure 65 facing the inside of the shell 1.

[0052] The application provides a rotation adjusting structure 64 with a clear sense of segmentation. The application takes the application of the rotation adjusting structure 64 in the display device 6 of a flow meter as an example for illustration, and through the specific structure described, it can be known that the rotation adjusting structure 64 can also be applied to the rotation adjustment of the cover and the shell in other fields, which will not be further expanded here.

[0053] The application introduces an innovative rotation adjusting structure 64, which is characterized by providing a clear sense of segmentation to enhance user experience. In order to specifically illustrate the characteristics and application effects of this structure, we take its application in the display device 6 of a flow meter as an example for illustration, and point out that this structure also has broad application potential and can be promoted to the rotation adjustment of the cover and the shell in other fields, but will not be further expanded here.

[0054] In the specific application scenario of the display device 6 of a flow meter, the rotation adjusting structure 64 is carefully designed and integrated, so that the user can experience a clear sense of segmentation when adjusting the angle or position of the display device 6. This design not only improves the accuracy and stability of the adjustment process, but also makes the display device flexible to adapt to the viewing needs of different users, thereby improving the convenience and efficiency of flow monitoring.

[0055] Through this example, we can clearly see the advantages and potential of the rotation adjusting structure 64 in actual application, and also provide a beneficial reference for its application in other fields, which will not be further expanded here.

[0056] The specific embodiments of the application are described in detail above, and for those skilled in the art, some improvements and modifications can be made to the application without departing from the principles of the application, and these improvements and modifications also belong to the protection scope of the claims of the application.
