[0027] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0028] It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0029] Referring to Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a transmitter, and the transmitter can be a pressure transmitter, a temperature transmitter, a flow transmitter, a liquid level transmitter, a current transmitter or a voltage transmitter. The transmitter includes: a display screen assembly 100 and a base assembly 200. A buckle 103 is provided on the display screen assembly 100;

[0030] The base assembly 200 includes a base 210 having an accommodation cavity. At least two azimuth angle grooves 201 are circumferentially arranged on the base 210 for adapting to the buckle 103. The groove 201 can be a rectangular groove, a V-shaped groove or an opening groove of other shapes, so that the buckle 103 can be smoothly positioned and locked when inserted. The display screen assembly 100 is snap-fitted into the groove 201 at the corresponding azimuth angle through the buckle 103 to adjust and change the angle of the display screen assembly relative to the base assembly. In a specific application scenario, the user can select the buckle to be adapted and snap-fitted with the grooves at different azimuth angles according to actual needs to realize the adjustment of the installation angle of the display screen assembly and meet the requirements in various application scenarios.

[0031] The transmitter provided by the embodiment of the utility model improves its structure, sets a buckle on the display screen assembly, and sets grooves at at least two azimuth angles on the surface of the base assembly for matching with the buckle. When the display screen assembly needs to be adjusted in azimuth, the buckle only needs to be inserted into the grooves at different azimuth angles to simply adjust the angle of the display screen assembly relative to the base assembly. In addition, the buckle and the groove are used to engage with each other to ensure a stable connection between the display screen assembly and the base assembly. Thus, it is easy to achieve a relatively simple and reliable angle adjustment of the transmitter display screen assembly.

[0032] Continue to view Figure 1 and Figure 3 In some embodiments, the display screen assembly includes a housing 101 and a display screen 102, and the display screen 102 is placed in the housing 101. The housing 101 can be designed to have an integrated structure or a split structure. In order to ensure durability and stability in an industrial environment, the housing 101 can be made of high temperature resistant and impact resistant materials, such as polycarbonate or aluminum alloy.

[0033] The outer shape of the housing 101 can be designed as a cylindrical surface, a cuboid with rounded corners, or other curved surface shapes, etc. A supporting structure such as a reinforcing rib or a partition can be provided inside the housing 101 to improve the overall rigidity and prevent deformation, and the surface of the housing 101 can also be surface treated.

[0034] The buckle 103 is disposed on the housing 101, and the buckle 103 includes a buckle portion 104 extending from the bottom of the housing 101. The buckle portion 104 may be located at a position deviated from the edge of the bottom of the housing. A wire hole 110 is disposed at the bottom of the housing 101, and a flexible cable (not shown in the figure) is passed through the wire hole 110 to electrically connect the display screen 102 with the control board 220.

[0035] In this embodiment, a buckle is provided on the shell of the display screen assembly, and the buckle includes a buckle portion extending to the bottom of the shell, and grooves at at least two azimuth angles for matching with the buckle are provided on the surface of the base assembly, specifically grooves engaged with the buckle portion. When the display screen assembly needs to be adjusted in azimuth, it is only necessary to insert the buckle portion into the grooves at different azimuth angles to simply adjust the angle of the display screen assembly relative to the base assembly. In addition, the engagement between the buckle portion and the groove can ensure a secure connection between the display screen assembly and the base assembly.

[0036] To further improve the convenience of angle adjustment of the display assembly, see Figure 1 and Figure 3As shown, the buckle 103 further includes a pressing portion 105 located on the side of the housing 101. The pressing portion 105 is configured as a separate area to facilitate quick positioning of this area by the user and applying pressure to bend the buckling portion. The position of the pressing portion 105 is generally set at a position easily accessible by the user, such as on the side close to the display screen assembly, so as to quickly unlock the buckling portion from the groove.

[0037] In this embodiment, when the angle of the display screen needs to be adjusted, pinch the pressing portion 105 of the buckle 103 with the hand, and the buckling portion 104 of the buckle 103 can be bent and disengaged from the groove, and the display screen assembly can be quickly removed and inserted into the groove at the corresponding angle, thereby realizing the angle adjustment of the display screen assembly.

[0038] Specifically, the buckle 103 is made of a material with elastic deformation. When the pressing portion 105 of the buckle 103 is pressed, the buckling portion 104 of the buckle 103 can have a certain degree of bending deformation, that is, bend along the direction of the pressing force, so as to facilitate detachment from the groove 201. After being detached from the groove 201, under the action of elastic deformation, the buckling portion 104 returns to its original shape. In some embodiments, the buckle is a plastic or sheet metal buckle.

[0039] Specifically, the bottom of the buckling portion 104 has a barb structure or a flanging structure, and the barb structure or the flanging structure faces the outside of the housing 101. When the buckling portion 104 is inserted into the groove 201, the barb structure or the flanging structure can effectively hook the inner wall of the groove, thereby preventing the buckling portion 104 from accidentally falling off during use and improving the reliability of the connection.

[0040] Specifically, a groove-shaped structure matching the barb structure or the flanging structure can also be provided on the inner wall of the groove 201. When the buckling portion 104 is inserted into the groove 201, the barb structure or the flanging structure will slide into the groove, thereby realizing clamping, so as to ensure that the buckling portion 104 can smoothly enter and be firmly locked at different angle adjustments.

[0041] See Figure 2 and Figure 5 As shown, specifically, a notch 1013 is provided on the side of the housing 101 to form an area for setting the pressing portion. The pressing portion 105 is provided in the notch 1013 and extends from the top of the housing 101. The two sides of the pressing portion 105 are disconnected from the position of the notch 1013 where the side of the housing 101 is located. By providing the pressing portion 105 on the side of the housing and disconnecting its two sides from the position of the notch 1013 where the side of the housing 101 is located, when the angle of the display screen assembly needs to be adjusted, it is convenient to drive the buckling portion 104 to bend and disengage from the groove 201 by pressing the pressing portion 105, thereby facilitating the angle adjustment operation of the display screen assembly.

[0042] In order to increase the identifiability and anti-slip property of the pressing part 105, in some embodiments, the outer surface of the pressing part 105 is provided with a concavo-convex structure, which can be formed on the outer surface of the pressing part 105 by processes such as stamping or integral injection molding. In this embodiment, by providing a concavo-convex structure on the surface of the pressing part 105, not only can its identifiability be increased, but also the friction with the user's finger can be increased, ensuring that it will not slide when pressure is applied, thereby improving the reliability of operation.

[0043] Specifically, the concavo-convex structure is an interval stripe-shaped concavo-convex structure.

[0044] Refer to Figure 3 As shown, in some embodiments, the housing 101 includes a top cover 1131 and a bottom cover 1132 docked with the top cover 1131. A window 107 is opened on the surface of the top cover 1131, and the display screen 102 is disposed inside the top cover 1131 corresponding to the window 107. A buckle avoidance opening 108 is provided on the bottom cover 1132, and the buckle portion 104 is formed from the side of the top cover 1131 and passes through the buckle avoidance portion 108 of the bottom cover 1132. This enables the buckle portion 104 to smoothly enter the groove 201 during adjustment without being blocked by the bottom cover 1132.

[0045] Specifically, a first card slot 1133 is provided on the side of the top cover 1131, and a first buckle 1134 is provided on the side of the bottom cover 1132 docked with the top cover 1131. The bottom cover 1132 is embedded in the top cover 1131 and is snap-connected through the first card slot 1133 and the first buckle 1134.

[0046] To enhance the adjustment and connection stability between the transmitter display screen assembly and the base assembly, continue to refer to Figure 5 In some embodiments, there are at least two buckles 103, and the at least two buckles 103 are symmetrically arranged on the side of the housing 101.

[0047] Refer to Figure 4 As shown, to further improve the adaptability of the transmitter in different application scenarios, in some embodiments, at least two grooves 201 are arranged in a circular array along the circumference of the base 210, allowing the user to select between multiple angles of the display screen assembly relative to the base assembly, so that the display screen assembly can be flexibly adjusted according to actual needs.

[0048] Continue to refer to Figure 1 or Figure 4 As shown, in some other embodiments, at least two of the grooves 201 are arranged in a circular array along the circumference of the base 210, and can be arranged with equal or unequal radian, and when the user adjusts the display screen assembly, different angles can be selected for locking according to actual needs.

[0049] Among them, in the case of equal radian layout, the angles between the respective grooves 201 are the same, forming a uniformly distributed structure. In the case of unequal radian layout, the angles between the respective grooves 201 can be flexibly designed according to actual usage requirements to meet the special requirements for the display screen angle in a specific application scenario. In this embodiment, by adopting grooves with equal and unequal radian layouts, the transmitter can adapt to a wider range of usage environments, improving the adaptability of the device.

[0050] Specifically, the base 210 includes: a base top shell 211 and a base bottom cover 212 docked with the base top shell 211. A second card slot 213 is provided on the side of the base top shell 211, and a second buckle 214 is provided on the side of the base bottom cover 212. The base bottom cover 212 is embedded in the base top shell 211 and is snap-connected through the second card slot 213 and the second buckle 214.

[0051] When installing the transmitter, the base assembly 200 can be first fixed at a predetermined position of the applied product through the connecting member 220, and then the display screen assembly 100 can be installed into the groove 201 of the base assembly 200 through the buckle 103 according to needs to achieve assembly.

[0052] When it is necessary to adjust the installation azimuth angle of the display screen assembly, by pinching the pressing portion 105 of the buckle 103 with the hand, the buckling portion 104 bends inward and disengages from the groove 201 to achieve the quick separation between the display screen assembly 100 and the base assembly 200.

[0053] Then, according to the required azimuth angle, the display screen assembly 100 is inserted into the groove 201 at the predetermined azimuth angle through the buckle 103, thereby realizing simple, quick and reliable adjustment of the installation azimuth angle of the display screen assembly.

[0054] In summary, for the transmitter provided by the embodiment of the present invention, through the improvement of its structure, a buckling portion extending to the bottom is provided on the housing of the display screen assembly, and at least two azimuth angles of grooves for matching with the buckle are provided on the surface of the base assembly. When it is necessary to adjust the azimuth angle of the display screen assembly, only by inserting the buckling portion into the grooves at different azimuth angles, the angle of the display screen assembly relative to the base assembly can be simply adjusted; in addition, by using the cooperation and snap connection of the buckling portion and the groove, the stable connection between the display screen assembly and the base assembly can also be ensured. Thus, it is convenient to realize relatively simple and reliable angle adjustment of the display screen assembly of the transmitter.
