Abstract
Description
Technical Field
[0001] This utility model relates to the field of fluid measurement technology, specifically to an electromagnetic flowmeter that is easy to assemble and disassemble. Background Technology
[0002] Electromagnetic flowmeters commonly encounter problems during installation and maintenance in industrial settings, such as complex disassembly, difficulty in ensuring sealing, and damage to the sealing surface from repeated disassembly and assembly. Traditional flange connections require specialized tools for bolt tightening, resulting in low work efficiency and the risk of bolt stripping.
[0003] According to a public disclosure (Publication No.: CN222652299U), a hydraulic tilting rack and hydraulic tilting device include: a sensor housing and a converter housing. A measuring tube is inserted into the middle of the sensor housing, with both ends of the measuring tube passing through the two sides of the sensor. A magnetic ring is provided inside the sensor housing, and the magnetic ring is sleeved on the peripheral wall of the measuring tube. A coil is sleeved on the outer peripheral wall of the magnetic ring, and the coil is connected to the inner wall of the sensor housing by a bracket. A connecting post is provided at one end of the sensor housing, and the peripheral wall of the connecting post has external threads. A processor is provided inside the converter housing, and the processor is used to process the electrical signal measured by the measuring tube. A connecting tube is provided at one end of the converter housing, and the inner peripheral wall of the connecting tube has internal threads. The connecting tube is threadedly connected to the connecting post. This utility model provides an electromagnetic flowmeter that is easy to disassemble and assemble. It adopts a modular design, designing the sensor and converter board as independent modules, which are easy to disassemble and assemble, and convenient for users to maintain, replace, and carry.
[0004] In the aforementioned applications, disassembly also requires a significant amount of time and effort to unscrew the bolts. If the bolts are rusty or damaged, it will further increase the difficulty of disassembly, affecting the equipment's maintenance efficiency and replacement cycle. This not only reduces production efficiency but also increases maintenance costs, adversely impacting the continuity of industrial production. Utility Model Content
[0005] This invention proposes an electromagnetic flowmeter that is easy to assemble and disassemble, solving the problems in related technologies that not only reduce production efficiency but also increase maintenance costs and adversely affect the continuity of industrial production.
[0006] According to one aspect, at least one embodiment of this disclosure provides a conveniently detachable electromagnetic flow meter, comprising: a flow meter, a protective housing threadedly connected to the side of the flow meter, a control panel disposed inside the protective housing, a nameplate, an interface, and a pipe fixedly connected to the circumferential surface of the flow meter, and convenient installation and removal devices provided at both ends of the pipe.
[0007] The convenient assembly and disassembly device includes a tension spring, one end of which is fixedly connected to the inner wall side of one end of the pipe, and the other end of which is fixedly connected to a transmission plate. An L-shaped locking block is fixedly connected to one side of the transmission plate, and a connecting post is fixedly connected to the side of the L-shaped locking block. A manual locking ring is fixedly connected to one end of the connecting post. A protective shell is slidably connected to the circumferential surface of the transmission plate. One end of the protective shell is fixedly connected to the inner wall side of one end of the pipe away from the tension spring. A limit groove is formed on the circumferential surface of the protective shell. The circumferential surface of the connecting post is slidably connected to the inner wall side of the limit groove. Connecting pipes are provided at both ends of the pipe, and a pawl is fixedly connected to the end of the connecting pipe closest to the pipe.
[0008] For example, in at least one embodiment of this disclosure, an electromagnetic flowmeter designed for easy assembly and disassembly is provided, further comprising: the inner circumferential surface of the transmission plate is slidably connected to the circumferential surface of the pipe; the L-shaped side of the L-shaped locking block is an arc surface; and the transmission plate can slide smoothly along the circumferential surface of the pipe. At the same time, the arc surface design of the L-shaped locking block reduces friction with the pipe, improves the convenience of assembly and disassembly and the smoothness of operation, and ensures the stability and reliability of the connection.
[0009] The number of L-shaped locking blocks, connecting posts, and claws is six in total, and they are arranged in a circumferential array on the circumferential surface of the pipe. The uniform distribution of multiple L-shaped locking blocks, connecting posts, and claws enhances the connection strength between the flow meter and the connecting pipe.
[0010] The claws are not located on the displacement trajectory of the L-shaped locking block, nor on the displacement trajectory of the connecting column, thus avoiding mutual interference between components. This ensures that each component can move independently during assembly and disassembly without collision or jamming, improving the efficiency of assembly and disassembly and the overall stability of the equipment.
[0011] The claw penetrates one side of the pipe, and the end of the claw away from the connecting pipe slides on the circumferential surface of the pipe, allowing it to slide flexibly on the circumferential surface of the pipe, facilitating quick docking and separation with the connecting pipe. At the same time, the through-hole design enhances the firmness of the connection.
[0012] According to another aspect, at least one embodiment of this disclosure also provides a solution for an easily detachable electromagnetic flowmeter, comprising: a locking device provided at one end of the easy-to-install and disassemble device, the locking device including a spring base plate, the inner circumferential surface of the spring base plate being slidably connected to the circumferential surface of a connecting pipe, a locking force spring being fixedly connected to the side of the connecting pipe near the easy-to-install and disassemble device away from the chuck, one end of the locking force spring being fixedly connected to one side of the spring base plate, a locking pin being fixedly connected to the spring base plate, the locking pin penetrating the side of the connecting pipe near the easy-to-install and disassemble device, and a locking groove being provided on the side of the L-shaped locking block.
[0013] For example, in at least one embodiment of the present disclosure, an electromagnetic flowmeter that is easy to assemble and disassemble is provided, which further includes: the locking groove is located on the displacement trajectory of the locking column, and one end of the locking column is provided with a rounded corner, which ensures that the locking column can accurately cooperate with the locking groove to achieve fast locking and unlocking. The rounded corner design reduces the friction between the locking column and the locking groove and improves the efficiency of locking and unlocking.
[0014] The locking pin is located inside the locking force spring. The displacement trajectory of the locking force spring is greater than the exposed diameter of the locking pin through the connecting pipe. The locking force spring can provide uniform elastic force on the outside of the locking pin to ensure that the locking pin remains stable during displacement.
[0015] The number of locking pins and locking grooves is set to six, and they are all arranged in a circumferential array on the circumferential surface of the pipe. The uniform distribution of multiple locking pins and locking grooves enhances the connection strength between the flow meter and the connecting pipe, ensuring stability and sealing during the fluid measurement process. At the same time, this symmetrical design helps to improve the efficiency of assembly and disassembly and the accuracy of the connection.
[0016] Two locking devices are provided and are symmetrical to each other along the vertical central axis of the pipe. The installation of the locking devices at both ends helps to improve work efficiency.
[0017] The working principle and beneficial effects of this utility model are as follows:
[0018] 1. This utility model achieves rapid assembly and disassembly of the flow meter through a convenient assembly and disassembly device. The transmission plate slides on the outer surface of the pipe, and the L-shaped locking block and connecting column lock and unlock the flow meter through a manual locking ring, with a tension spring providing a restoring force. The clamps are fixed to the connecting pipe to ensure the stability of the connection. This design eliminates the need for special tools when assembling and disassembling the flow meter, simplifying operation, saving time and effort, greatly improving work efficiency, and reducing maintenance costs.
[0019] 2. This utility model further enhances the reliability of the connection through a locking device. The locking force spring pushes the locking pin into the locking groove, achieving automatic locking. The rounded corner design at one end of the locking pin facilitates precise matching between the locking pin and the locking groove. The locking pin is located inside the locking force spring, and the displacement trajectory of the locking force spring is greater than the exposed diameter of the locking pin, ensuring the locking pin remains stable during compression and rebound, providing continuous locking force. Multiple locking pins and locking grooves are evenly distributed along the circumference of the pipe, enhancing the tightness and sealing of the connection. The symmetrically arranged locking device ensures uniform force on the flow meter on the pipe, preventing loosening or damage due to uneven force, further improving the overall stability and reliability of the equipment.

[0027] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.
[0028] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0031] like Figures 1-5 As shown, it illustrates an embodiment of the present disclosure of an easily disassembled electromagnetic flowmeter, comprising: a flowmeter 1, a protective shell 2 threadedly connected to the side of the flowmeter 1, a control panel 3 disposed inside the protective shell 2, a nameplate 4 fixedly connected to the circumferential surface of the flowmeter 1, an interface 5 fixedly connected to the circumferential surface of the flowmeter 1, a pipe 6 fixedly connected to the circumferential surface of the flowmeter 1, and convenient disassembly devices 7 disposed at both ends of the pipe 6.
[0032] The convenient assembly and disassembly device 7 includes a tension spring 701. One end of the tension spring 701 is fixedly connected to the inner wall side of one end of the pipe 6. The other end of the tension spring 701 is fixedly connected to a transmission plate 702. One side of the transmission plate 702 is fixedly connected to an L-shaped locking block 703. The side of the L-shaped locking block 703 is fixedly connected to a connecting post 704. One end of the connecting post 704 is fixedly connected to a manual locking ring 705. A protective shell 706 is slidably connected to the circumferential surface of the transmission plate 702. One end of the protective shell 706 is fixedly connected to the inner wall side of one end of the pipe 6 away from the tension spring 701. A limiting groove 707 is opened on the circumferential surface of the protective shell 706. The circumferential surface of the connecting post 704 is slidably connected to the inner wall side of the limiting groove 707. Connecting pipes 708 are provided at both ends of the pipe 6. A claw 709 is fixedly connected to the end of the connecting pipe 708 closest to the pipe 6.
[0033] In some examples, the inner circumferential surface of the transmission plate 702 is slidably connected to the circumferential surface of the pipe 6, and the L-shaped locking block 703 has an arc-shaped side surface, with one side slidably connected to the circumferential surface of the pipe 6. The transmission plate 702 can slide smoothly along the circumferential surface of the pipe 6, while the arc-shaped design of the L-shaped locking block 703 reduces friction with the pipe 6, improving the convenience of assembly and disassembly and the smoothness of operation, and ensuring the stability and reliability of the connection.
[0034] There are six L-shaped locking blocks 703, six connecting posts 704, and six claws 709 arranged in a circumferential array on the circumferential surface of the pipe 6. The uniform distribution of multiple L-shaped locking blocks 703, connecting posts 704, and claws 709 enhances the connection strength between the flow meter 1 and the connecting pipe 708.
[0035] The pawl 709 is not located on the displacement trajectory of the L-shaped locking block 703, nor on the displacement trajectory of the connecting column 704, thus avoiding mutual interference between components and ensuring that each component can move independently during assembly and disassembly without collision or jamming, thereby improving the efficiency of assembly and disassembly and the overall stability of the equipment.
[0036] The claw 709 penetrates one side of the pipe 6, and the end of the claw 709 away from the connecting pipe 708 is slidably connected to the circumferential surface of the pipe 6, allowing it to slide flexibly on the circumferential surface of the pipe 6, facilitating quick docking and separation with the connecting pipe 708. At the same time, the through-hole setting enhances the firmness of the connection.
[0037] For example, such as Figures 1-5As shown, the convenient assembly / disassembly device 7 enables the rapid connection and separation of the flow meter 1 and the pipeline 6 through manual operation of the manual locking ring 705 and the elastic action of the tension spring 701. Specifically, when disassembling the flow meter 1, manually rotating the manual locking ring 705 overcomes the elastic force of the tension spring 701, causing the connecting column 704 and the L-shaped locking block 703 to move, disengaging the clamp 709 from the connection position, thus quickly separating the flow meter 1 from the pipeline 6. Conversely, when assembling the flow meter 1, the operation is reversed: aligning the clamp 709 with the connection position and releasing the manual locking ring 705 allows the clamp 709 to automatically lock onto the pipeline 6 under the restoring force of the tension spring 701, completing the rapid assembly of the flow meter 1. The tension spring 701 provides the necessary restoring force for the entire device, ensuring a smooth and convenient assembly / disassembly process.
[0038] like Figures 1-5 As shown, this illustrates an electromagnetic flowmeter that is easy to assemble and disassemble in another embodiment of this disclosure. The technical solution is largely the same as that of Embodiment 1, so only the differences are described. These differences include: a locking device 8 is provided at one end of the easy-to-assemble / disassemble device 7. The locking device 8 includes a spring base plate 801, the inner circumferential surface of which is slidably connected to the circumferential surface of the connecting pipe 708. A locking force spring 802 is fixedly connected to the side of the connecting pipe 708 near the easy-to-assemble / disassemble device 7, away from the claw 709. One end of the locking force spring 802 is fixedly connected to one side of the spring base plate 801. A locking pin 803 is fixedly connected to the spring base plate 801, penetrating the side of the connecting pipe 708 near the easy-to-assemble / disassemble device 7. A locking groove 804 is provided on the side of the L-shaped locking block 703.
[0039] In some examples, the locking groove 804 is located on the displacement trajectory of the locking pin 803, and one end of the locking pin 803 is rounded. This design ensures that the locking pin 803 can precisely engage with the locking groove 804, enabling rapid locking and unlocking. The rounded corner design reduces friction between the locking pin 803 and the locking groove 804, improving the efficiency of locking and unlocking.
[0040] The locking pin 803 is located inside the locking force spring 802, and the displacement trajectory of the locking force spring 802 is greater than the exposed diameter of the locking pin 803 through the connecting pipe 708. The locking force spring 802 can provide uniform elastic force on the outside of the locking pin 803, ensuring that the locking pin 803 remains stable during displacement.
[0041] Six locking posts 803 and locking grooves 804 are provided, all arranged in a circumferential array on the circumferential surface of the pipe 6. The uniform distribution of multiple locking posts 803 and locking grooves 804 enhances the connection strength between the flow meter 1 and the connecting pipe 708, ensuring stability and sealing during fluid measurement. Simultaneously, this symmetrical design helps improve assembly / disassembly efficiency and connection accuracy.
[0042] Two locking devices 8 are provided, and they are symmetrical to each other along the vertical central axis of the pipe 6. The installation of locking devices 8 at both ends helps to improve work efficiency.
[0043] For example, such as Figures 1-5 As shown, the locking device 8 mainly consists of a locking pin 803, a locking force spring 802, a spring base plate 801, and a locking groove 804. When the flow meter 1 needs to be connected to the pipe 6, the locking pin 803, under the elastic force of the locking force spring 802, automatically moves towards the locking groove 804 and precisely embeds itself into the locking groove 804, thereby achieving rapid locking between the flow meter 1 and the pipe 6. The displacement trajectory of the locking force spring 802 is greater than the exposed diameter of the locking pin 803, ensuring that the locking pin 803 remains stable during movement and does not tilt or jam. The number of locking pins 803 and locking grooves 804 is set to six, and they are evenly distributed along the circumference of the pipe 6. This design not only enhances the firmness of the connection but also ensures the uniformity and sealing of the connection between the flow meter 1 and the pipe 6, while improving the efficiency of assembly and disassembly and the accuracy of the connection.
[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
