Technical Field

[0001] This application relates to a display component and a transmitter, belonging to the field of metering device technology. Background Technology

[0002] A transmitter is a device that converts analog signals output from sensors into standard signals, typically used in industrial measurements. The working principle of a transmitter involves converting various physical quantities (such as current, voltage, power, frequency, temperature, weight, position, and pressure) into transmittable DC analog electrical signals. The display module is a crucial component of the transmitter, displaying the converted electrical signals as text information.

[0003] Currently, in order to install the display module in the transmitter, the display module is fixed to the transmitter housing with bolts. This results in a complex transmitter structure and makes the transmitter inconvenient to install. Utility Model Content

[0004] This application provides a display component and a transmitter, which solves the problem of complex disassembly and assembly of the display module of the transmitter in the related art.

[0005] In a first aspect, this application provides a display component, including:

[0006] The bracket includes a base and a plurality of buckles, the plurality of buckles being spaced apart circumferentially along the base, and one end of each buckle being connected to the base. The plurality of buckles surround and form an installation cavity, and at least one buckle has a slot.

[0007] The display element includes a snap-fit ​​portion, and at least a portion of the display element can be disposed within the mounting cavity;

[0008] The latching part can be latched into the slot, and the latching part and the inner wall of the slot can mutually limit each other in the rotation direction of the display component, and the latching part and the inner wall of the slot can mutually limit each other in the direction of the display component away from the base.

[0009] In some embodiments, the display component further includes a display body, the snap-fit ​​portion is elastically connected to the periphery of the display body, a portion of the display body is surrounded by a plurality of the snaps, and the snap-fit ​​portion can pass through the snap slot.

[0010] In some embodiments, each of the multiple buckles is provided with a slot, and there are multiple snap-fit ​​parts, which are snapped into the multiple slots respectively.

[0011] In some embodiments, the outer wall of the snap-fit ​​portion abuts against the inner wall of the snap-fit ​​groove.

[0012] In some embodiments, the slot is a strip-shaped groove, the length direction of the slot is the axial direction of the base, one end of the snap-fit ​​portion abuts against the inner wall of the slot facing the base, and the other end of the snap-fit ​​portion has a gap with the inner wall of the opposite slot.

[0013] In some embodiments, the slot has two first limiting inner walls that are distributed circumferentially and opposite to each other along the mounting cavity. In the circumferential direction of the mounting cavity, the latching portion has a width, and the slot has a notch. In the direction away from the display body and in the orientation of the notch of the slot, the width of the latching portion gradually decreases, so that the distance between the outer wall of the latching portion and the two first limiting inner walls gradually increases, and the maximum width of the latching portion is greater than the distance between the two first limiting inner walls.

[0014] In some embodiments, the slot further has a second limiting inner wall facing the base, and the snap-fit ​​portion has a positioning surface facing the second limiting inner wall;

[0015] In the direction away from the display body of the latching portion, and in the orientation of the slot opening of the card slot, the distance between the positioning surface and the base gradually decreases.

[0016] In some embodiments, the display element further includes a limiting surface, and the end of the buckle facing away from the base abuts against the limiting surface.

[0017] In some embodiments, the display element further includes a plurality of positioning pieces, which are spaced apart circumferentially on the end side of the display body. The orthographic projection of the positioning piece toward the display element is spaced apart from the edge of the display body. A plurality of buckles surround the positioning pieces, and the limiting surface is located at the edge of the display body.

[0018] In some embodiments, the display element further includes a plurality of springs, which are alternately arranged with the plurality of positioning pieces along the circumference of the display body. One end of each spring is elastically connected to any one of the adjacent positioning pieces. The snap-fit ​​portion is disposed on the spring, which is configured to be driven to move away from the snap-fit. The limiting surface is located between the edge of the display body and the spring.

[0019] Secondly, based on the display component described above, this application also proposes a transmitter that includes the display component described above.

[0021] In the display assembly provided in this application, multiple latches in the bracket are spaced circumferentially along the base, forming a mounting cavity. At least a portion of the display element is located within the mounting cavity and is surrounded by the latches. These latches effectively limit the position of the display element, preventing it from moving away from the mounting cavity in the direction of the latches. The latching portion of the display element is located within the latch groove, and the latching portion and the inner wall of the groove mutually limit each other in the rotation direction of the display element, allowing the display element to be fixed relative to the bracket in its rotation direction, thus securing it to the bracket. The latches are elastically connected to the base, allowing them to move away from the mounting cavity. This allows the latching portion to move away from the groove and separate from it. The latching portion and groove no longer mutually limit each other, and the display element can be driven to rotate until the latching portion separates from the groove, allowing the display element to be detached from the bracket. Therefore, the display assembly of this application is simple and convenient to install and maintain.

[0022] The transmitter provided in this application includes the display component mentioned above, which makes the transmitter assembly and disassembly process simple and convenient, thereby making the transmitter easy to install and maintain. Attached Figure Description

[0042] A transmitter is a device that converts analog signals output from sensors into standard signals, typically used in industrial measurements. The working principle of a transmitter involves converting various physical quantities (such as current, voltage, power, frequency, temperature, weight, position, and pressure) into transmittable DC analog electrical signals. The display module is a crucial component of the transmitter, displaying the converted electrical signals as text information.

[0043] Currently, in order to install the display module in the transmitter, the display module is fixed to the transmitter housing with bolts. This results in a complex transmitter structure and makes the transmitter inconvenient to install.

[0044] In the display assembly proposed in this application, multiple latches in the bracket are spaced circumferentially along the base, forming a mounting cavity. At least a portion of the display element is located within the mounting cavity and is surrounded by the latches. These latches effectively limit the position of the display element, preventing it from moving away from the mounting cavity in the direction of the latches. The latching portion of the display element is located within the latch groove, and the latching portion and the inner wall of the groove mutually limit each other in the rotation direction of the display element, thus fixing the display element relative to the bracket in that direction and securing it to the bracket. The latches are elastically connected to the base, allowing them to move away from the mounting cavity. This allows the latching portion to move away from the groove and separate from it. With the latching portion and groove no longer mutually limiting each other, the display element can be driven to rotate until the latching portion separates from the groove, allowing the display element to be detached from the bracket. Therefore, the assembly and disassembly process of the display assembly of this application is simple and convenient, facilitating installation and maintenance.

[0045] The transmitter proposed in this application includes the display component mentioned above, which makes the transmitter assembly and disassembly process simple and convenient, thereby making the transmitter easy to install and maintain.

[0046] The display component and transmitter provided in this application will be described in detail below with reference to specific embodiments.

[0047] refer to Figures 1 to 2 As shown, the display assembly proposed in this application includes a bracket 100 and a display element 200. This display assembly can be applied in a transmitter.

[0048] The bracket 100 is the basic component of the display assembly of this application. The bracket 100 provides a mounting base for at least some other components of the display assembly and serves to protect those components. The bracket 100 can be made of metal, giving it better structural strength, thus improving its durability and reliability. Alternatively, the bracket 100 can be made of polymer materials, allowing it to maintain a certain structural strength while remaining relatively lightweight.

[0049] The bracket 100 includes a base 110 and a plurality of latches 120, which are spaced apart circumferentially along the base 110. Specifically, the latches 120 can form a mounting cavity 122. The bottom wall of the mounting cavity 122 is one side surface of the base 110, and the inner sidewall of the mounting cavity 122 is the sidewall of the latches 120. The latches 120 can be arranged along the edge of the base 110, which allows for a larger volume in the mounting cavity 122, thus enabling a larger volume of components that can be accommodated within it. One end of the latches 120 away from the base 110 can form an opening communicating with the mounting cavity 122, through which a display component can be installed within the mounting cavity 122.

[0050] At least a portion of the display element 200 is disposed within the mounting cavity 122 of the bracket 100. Therefore, the circumferential outer wall of the display element 200 can be opposite to a plurality of latches 120. The plurality of latches 120 can limit the position of the display element 200 and prevent the display element 200 from moving in the direction toward the latches 120 and detaching from the mounting cavity 122, thereby fixing the display element 200 to the bracket 100 to a certain extent.

[0051] Specifically, when the display element 200 is located within the mounting cavity 122, its circumferential sidewall can be positioned to abut against multiple latches 120. This reduces the range of motion of the display element 200, allowing it to be better secured to the bracket 100. Furthermore, the abutment between the circumferential sidewall of the display element 200 and the latches 120 generates friction. This friction provides resistance between the display element 200 and the latches 120 in the circumferential direction of the base 110, thus preventing the display element 200 from rotating circumferentially along the base 110 without external force.

[0052] The buckle 120 has a slot 121, and the display component 200 includes a latching portion 220. The opening of the slot 121 faces the display component 200, and the groove shape of the slot 121 matches the shape of the latching portion 220, allowing the latching portion 220 of the display component 200 to be latched into the slot 121 of the buckle 120. One end of the buckle 120 is connected to the base 110. At least one of the latching portion 220 and the buckle 120 can move in opposite directions, allowing the buckle 120 to move relative to the base 110 in a direction away from the display component 200, or allowing the latching portion 220 to move relative to the buckle 120 in a direction away from the buckle 120, thereby allowing the latching portion 220 to disengage from the slot 121 of the buckle 120, thus separating the latching portion 220 from the slot 121.

[0053] Specifically, the display component 200 includes a first state and a second state. When the display component 200 is disposed in the mounting cavity 122 of the bracket 100, it can be driven by an external force to rotate relative to the bracket 100 along the circumference of the base 110, thereby switching between the first state and the second state. When the display component 200 is in the first state, the locking part 220 is locked in the slot 121 of the buckle 120, and the locking part 220 and the inner wall of the slot 121 are phase-limited in the circumferential direction of the base 110. That is, the locking part 220 and the inner wall of the slot 121 can mutually limit each other in the rotatable direction of the display component 200, thereby allowing the display component 200 to be relatively fixed to the bracket 100 in its rotatable direction, so as to better fix the display component 200 and the bracket 100 together.

[0054] When the display component 200 is in the second state, the latching part 220 and the buckle 120 are misaligned, thereby separating the latching part 220 from the buckle 120's slot 121. In this way, the latching part 220 and the bracket 100 are no longer mutually restrictive, allowing the display component 200 to be detached from the bracket 100.

[0055] When the display 200 switches from the first state to the second state, an external force can be applied to the latch 120 to move the latching part 220 away from the latch 120, causing the latching part 220 to disengage from the latching groove 121 of the latch 120. At this time, the latching part 220 and the inner wall of the latching groove 121 are not mutually restricted in the rotatable direction of the display 200, and the display 200 can be driven to rotate freely relative to the bracket 100. By driving the display 200 to rotate until the latching part 220 and the latch 120 are misaligned, the display 200 can be placed in the second state. At this time, if it is necessary to completely separate the display 200 from the bracket 100, an external force can be applied to drive the display 200 to move away from the base 110, so that the display 200 can be moved out of the opening on the bracket 100 to the outside of the mounting cavity 122 of the bracket 100, thus completely separating the display 200 from the bracket 100.

[0056] When the display element 200 switches from the second state to the first state, an external force can be applied to the locking part 220 to move it away from the latch 120, thereby reducing the friction between the latch 120 and the display element 200. Then, by rotating the display element 200, the locking part 220 of the display element 200 aligns with the latch groove 121 of the latch 120. After releasing the locking part 220, it can move towards the display element 200 under its own elastic restoring force, thus locking the locking part 220 into the latch groove 121 of the latch 120. In this way, the locking part 220 and the inner wall of the latch groove 121 mutually limit each other in the rotatable direction of the display element 200, thereby fixing the display element 200 to the bracket 100.

[0057] Therefore, when the display component 200 needs to be disassembled or reassembled, the display component 200 can be fixed or separated from the bracket 100 by driving the display component 200 to rotate relative to the bracket 100. This makes the disassembly and assembly process of the display component simple and convenient, and ultimately makes the display component easy to install and maintain.

[0058] In some implementations, reference Figures 1 to 2As shown, the display component 200 of this application specifically includes a display body 210. The display component is the main structure of the display component 200. When the display component of this application is applied to a transmitter, the display body 210 can be electrically connected to the circuit board assembly 400 of the transmitter. The snap-fit ​​portion 220 is elastically connected to the circumferential outer wall of the display body 210. At least a portion of the display body 210 can be disposed in the mounting cavity 122 of the bracket 100, so that multiple snap-fits 120 can abut against the circumferential side wall of the display body 210 to achieve the purpose of limiting the display component 200. Specifically, the mounting cavity 122 of the bracket 100 can be a cylindrical cavity, and the shape of the display body 210 can also be a cylindrical shape. The snap-fit ​​portion 220 is disposed on the circumferential side wall of the display body 210. When at least part of the main display body 210 is located in the mounting cavity 122 of the bracket 100, the snap-fit ​​part 220 is also located in the mounting cavity 122 so that the snap-fit ​​part 220 can snap into the slot 121 of the buckle 120.

[0059] Furthermore, to ensure the display body 210 is more stably positioned within the mounting cavity 122 of the bracket 100, the surface of the latch 120 facing the display body 210 can be configured as an arc surface that mates with the circumferential outer wall of the display body 210. This increases the contact area between the latch 120 and the display body 210, resulting in greater friction. This makes the connection between the display body 210 and the bracket 100 more stable.

[0060] In some implementations, reference Figures 1 to 2 As shown, to further improve the stability and reliability of the connection between the display component 200 and the bracket 100, multiple latches 120 can be provided, each with a slot 121. Correspondingly, the number of latching parts 220 of the display component 200 can be set to multiple, so that multiple latching parts 220 can be correspondingly latched into multiple slots 121. In this way, each latching part 220 can be positioned against the inner wall of the corresponding slot 121 in the rotation direction of the display component 200 and in the direction in which the display component 200 is away from the base 110.

[0061] Specifically, the number of snap-fit ​​parts 220 can be set to be the same as the number of slots 121 of the buckle 120, so that each snap-fit ​​part 220 can be snapped into the slot 121 of each buckle 120 in a one-to-one correspondence. Of course, the number of snap-fit ​​parts 220 can also be set to be greater than the number of slots 121 of the buckle 120, so that multiple snap-fit ​​parts 220 can be snapped into the same slot 121.

[0062] Furthermore, it should be understood that the number of slots 121 on any one of the clips 120 can also be set to multiple, which can further increase the number of slots 121 on the bracket 100, so as to further improve the connection stability and reliability between the display component 200 and the bracket 100.

[0063] In some implementations, reference Figures 3 to 4 As shown, in order to further improve the stability and reliability of the connection between the display component 200 and the bracket 100, when the display component 200 is in the first state, the inner wall of the latching part 220 abuts against the inner wall of the slot 121 of the buckle 120. In this way, the latching part 220 and the buckle 120 are connected more tightly, thereby making the connection between the display component 200 and the bracket 100 more tight.

[0064] Specifically, the slot 121 includes a bottom wall opposite to the base 110 and side walls on both sides of the bottom wall. The outer wall of the engaging part 220 abuts against both the bottom wall and the side walls of the slot 121, thereby fixing the engaging part 220 and the latch 120 relative to each other in the rotation direction of the display 200 and in the direction in which the display 200 is away from the base 110. Thus, when the engaging part 220 is disposed in the slot 121, there is no room for movement in the rotation direction of the display 200, nor in the direction in which the display 200 is away from the base 110, resulting in a tighter connection between the engaging part 220 and the latch 120.

[0065] To facilitate the installation of the latching part 220 into the slot 121 of the buckle 120, at least one of the latching part 220 and the buckle 120 can be made of a deformable structural component. This allows the latching part 220 and the buckle 120 to deform under a certain external force, enabling the latching part 220 to be engaged with the slot 121 of the buckle 120 by compression. Specifically, the latching part 220 and the buckle 120 can be made of plastic to avoid excessive structural strength that would prevent deformation.

[0066] In some implementations, reference Figures 1 to 4 As shown, the slot 121 of the buckle 120 of this application can be configured as a strip-shaped slot, and the length direction of the slot 121 is the axial direction of the base 110. By configuring the slot 121 as a strip-shaped slot, the length of the slot 121 can be increased, thereby reducing the material used in the buckle 120, reducing the manufacturing cost of the bracket 100, and thus reducing the cost of the display component of this application.

[0067] When the display component 200 is in the first state, one end of the latching part 220 can abut against the inner wall of the slot 121 facing the base 110, so that the latching part 220 and the inner wall of the slot 121 can mutually limit each other in the direction away from the base 110. The other end of the latching part 220 has a gap with the inner wall of the slot 121, so that there is a movable allowance between the inner wall of one side of the slot 121 and the latching part 220, thereby making it easier for the latching part 220 to be latched into the slot 121.

[0068] In some implementations, reference Figures 1 to 2As shown, to better fix the display element 200 to the bracket 100, the display element 200 may also be provided with a limiting surface 211. The limiting surface 211 abuts against the end of the latch 120 facing away from the base 110. In this way, the latch 120 can limit the display element 200 in the direction of the display element 200 toward the base 110, preventing the display element 200 from moving toward the base 110 under the action of external force, so that the display element 200 can remain stable. It should be understood that the latching part 220 and one side inner wall of the slot 121 mutually limit each other in the direction of the display element 200 away from the base 110, so that the display element 200 can remain relatively fixed to the base 110 when subjected to a force that causes it to move away from the base 110. Thus, the display element 200 can remain relatively fixed to the bracket 100 in the axial direction of the base 110, so that the display element 200 and the bracket 100 can remain relatively fixed in all directions.

[0069] For details, please refer to Figure 2 As shown, the display component 200 may also include a positioning piece 240, which is disposed on the end side of the display body 210 along the circumference of the display body 210, and the positioning piece 240 has a gap with the edge of the display body 210. Multiple buckles 120 are arranged around the positioning piece 240, and the limiting surface 211 is located between the edge of the display body 210 and the positioning piece 240.

[0070] In some implementations, reference Figures 1 to 2 As shown, in order to allow the snap-fit ​​portion 220 to be elastically connected to the display body 210, thereby making the switching process of the display component 200 between the first state and the second state simpler and more convenient, the display component 200 may also include a spring piece 230. One end of the spring piece 230 is elastically connected to the positioning piece 240, and the snap-fit ​​portion 220 is disposed on the spring piece 230. The outer wall of the spring piece 230 facing the buckle 120 can abut against the buckle 120, so that the spring piece 230 can support the buckle 120. Therefore, when the buckle 120 is sleeved on the spring piece 230, the end of the buckle 120 can abut against the limiting surface 211.

[0071] The spring 230 is configured to be driven to move away from the latch 120, that is, the spring 230 can be driven to move in a direction away from the latch 120, so that the spring 230 can drive the latching part 220 to disengage from the slot 121.

[0072] Specifically, when it is necessary to disengage the latching part 220 from the slot 121 of the latch 120, a force can be applied to the spring piece 230 to move the latching part 220 away from the slot 121. The spring piece 230 and the latch 120 move in opposite directions, which allows the latching part 220 to disengage from the slot 121 with a small degree of movement, thus making it easier for the latching part 220 to disengage from the slot 121.

[0073] The number of positioning pieces 240 and spring pieces 230 can be set to multiple, and multiple positioning pieces 240 and multiple spring pieces 230 can be alternately arranged along the circumference of the display body 210.

[0074] In some implementations, reference Figures 3 to 4 As shown, the latch 120 has a slot 121 with two opposing first limiting inner walls 121a distributed circumferentially along the mounting cavity 122. In the circumferential direction of the mounting cavity 122, the latching portion 220 has a width dimension, and the slot 121 has a notch. In the direction away from the display body 210 and towards the orientation of the notch in the slot 121, the width of the latching portion 220 gradually decreases, so that the distance between the outer wall of the latching portion 220 and the two first limiting inner walls 121a gradually increases. Therefore, the outer wall of the latching portion 220 opposite to the two first limiting inner walls 121a can be a beveled structure to form a guide surface 221. The maximum width of the latching portion 220 is greater than the distance between the two first limiting inner walls 121a, thus improving the effect of the latching portion 220 engaging within the slot 121.

[0075] When the display component switches from the second state to the first state, the latch 120 rotates toward the guide surface 221, and the side wall of the latch 120 abuts against the guide surface 221. The guide surface 221 guides the latch 120 to push the latching part 200 away from the latch 120. When the display component switches from the first state to the second state, the first limiting inner wall of the slot 121 rotates toward the guide surface 221, and the first limiting inner wall of the slot 121 abuts against the guide surface 221. The guide surface 221 guides the latching part 200 to move along the latch 120.

[0076] Specifically, the guide surface 221 is an inclined structure on the surface of the snap-fit ​​part 220. When the side wall of the buckle 120 or the first limiting inner wall of the slot 121 contacts the guide surface 221, the guide surface 221 can convert part of the force exerted by the buckle 120 in its rotation direction into a force that causes the snap-fit ​​part 220 to move away from the buckle 120, thereby increasing the distance between the buckle 120 and the snap-fit ​​part 220. The snap-fit ​​part 220 can be separated from the slot 121, or the buckle 120 can be rotated to cover the snap-fit ​​part 220, so that the snap-fit ​​part 220 can be snapped into the slot 121.

[0077] In some embodiments, the slot further has a second limiting inner wall 121b facing the base 110, and the engaging portion 220 has a positioning surface 212 facing the second limiting inner wall 121b. In the direction away from the display body 210 and in the orientation of the slot opening of the slot 121, the distance between the positioning surface 212 and the base 110 gradually decreases. The positioning surface 212 is also a beveled structure, and can guide the engaging portion 200 to separate from the latch 120.

[0078] Based on the display components described above, refer to Figure 5 As shown, this application also proposes a transmitter including the display component described above.

[0079] In some implementations, reference Figures 5 to 7 As shown, the transmitter of this application also includes a housing 300 and a circuit board assembly 400. The housing 300 is the basic component of the transmitter, providing a mounting base for at least some of the other components and protecting them. The housing 300 can be made of a metallic material, giving it better structural strength, thus improving its durability and reliability. Alternatively, the housing 300 can be made of a polymer material, allowing it to maintain structural strength while remaining relatively lightweight.

[0080] The housing 300 includes an inner cavity. The display component is disposed within the cavity 320 of the housing 300, and the circuit board assembly 400 is also disposed within the inner cavity of the housing 300, and is electrically connected to the display element 200. Thus, the housing 300 serves to protect the display component and the circuit board assembly 400. The circuit board assembly 400 can also be electrically connected to an external sensor. Analog signals output by the sensor can be transmitted to the circuit board assembly 400, which converts the analog signals into standard signals and sends them to the display component. The display element 200 of the display component converts the standard signals into text or image information for display.

[0081] To secure the display component to the housing 300, the base 110 can be bolted to the housing 300. Specifically, corresponding screw holes can be provided in the cavity 320 of the housing 300 and on the base 110. Bolts are passed through the screw holes on the base 110 and the housing 300 to secure the base 110 to the housing 300. The housing 300 can also have an observation port 330 communicating with the cavity 320. The display side of the display component 200 is opposite to the observation port 330. A transparent cover plate 310 can be provided at the observation port 330 so that the user can read the text or image information displayed by the display component 200 through the observation port 330.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
