Description

Technical Field

[0001] The present application relates to the technical field of flow metering equipment, and in particular to a wireless Internet of Things water meter with an anti-drop buckle structure. Background Art

[0002] When measuring flow, it is necessary to use metering equipment such as mechanical meters. Mechanical water meters are commonly used metering equipment. Traditional non-intelligent mechanical water meters cannot implement data transmission and recording. Existing wireless IoT water meters achieve data transmission and recording by adding a controller to the meter body.

[0003] The controller is generally connected to the meter body through an adapter (such as a pressure ring). In the prior art, the adapter is generally provided with a snap-on structure and snap-on connected to the meter body through the snap-on structure. The snap-on connection method requires the adapter to have a certain deformation ability. Since the deformable adapter itself has low strength, the adapter has weak deformation resistance. During the use of the wireless Internet of Things water meter, the wireless Internet of Things water meter will shake, and the adapter will be deformed by the force generated by the shaking of the wireless Internet of Things water meter, thereby causing the snap-on structure to deform, and the snap-on structure will fall off the meter body, making the snap-on connection between the adapter and the meter body unstable, and it is easy for the adapter and the controller to fall off the meter body.

The adapter comprises a ring body and three buckle structures, the three buckle structures are distributed along the circumference of the ring body and are located on the ring body, the adapter is snapped with the meter body through the three buckle structures, the adapter is provided with an annular snap groove arranged around the ring body; the controller is at least partially mounted on the adapter and fixedly connected with the adapter; the fixed ring is located in the annular snap groove and snapped with the annular snap groove, the fixed ring is mounted on the adapter and snapped with the adapter, and the fixed ring is also arranged around the ring body and abuts against the ring body.

[0007] Furthermore, a side wall of the annular groove is formed by a surface of the ring body portion on a side facing away from the buckle structure.

[0008] Furthermore, a clamping portion is provided at the opening of the annular groove, and the clamping portion at least partially extends toward the ring body portion. The clamping portion is elastic, and during the process of assembling the fixing ring to the annular groove, the clamping portion is deformed so that the fixing ring is located in the annular groove after passing through the clamping portion.

[0009] Furthermore, the minimum distance between the clamping portion and the ring body along the radial direction of the ring body is a first distance, the distance between the fixing ring along the radial direction of the ring body is a second distance, and the first distance is smaller than the second distance.

[0010] Further, when the fixing ring is located in the annular groove, the clamping portion abuts against the fixing ring, and the clamping portion has a supporting force to support the fixing ring.

[0011] Furthermore, a first guide angle structure is provided on a side of the clamping portion away from the bottom of the annular clamping groove.

[0012] Further, the fixing ring is provided with a second guide angle structure adapted to the first guide angle structure.

[0013] Furthermore, the controller is at least partially formed with an extension portion, and when the controller is fixed to the adapter, the extension portion abuts against a side of the clamping portion facing away from the fixing ring.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, a wireless Internet of Things water meter 100 with an anti-drop buckle structure is used for flow monitoring.

[0026] In order to clearly illustrate the technical solution of this application, the following is also defined: Figure 1 Front, back, left, right, up and down as shown.

[0027] Specifically, the wireless Internet of Things water meter 100 includes a meter body 110, an adapter 120, a controller 130 and a fixing ring 140. In some embodiments, along the up and down direction of the mechanical meter 100, the adapter 120 is located above the meter body 110, and at the same time, the adapter 120 is detachably assembled above the meter body 110. The controller 130 is located above the adapter 120, and the controller 130 is at least partially mounted on the adapter 120 and fixedly connected to the adapter 120. The fixing ring 140 is mounted on the adapter 120 and snapped with the adapter 120. The snap connection between the controller 130 and the meter body 110 is realized by the adapter 120. Among them, the fixing ring 140 can support the adapter 120, thereby improving the strength of the adapter 120 and the anti-deformation ability of the adapter 120. During the use of the wireless Internet of Things water meter 100, the above-mentioned setting makes it difficult for the adapter 120 to deform, thereby improving the stability of the snap connection between the adapter 120 and the meter body 110, avoiding the adapter 120 from falling off the meter body 110, and further preventing the controller 130 from falling off the meter body 120.

[0028] Specifically, the adapter 120 includes a ring body 121 and three buckle structures 122, and the three buckle structures 122 are distributed along the circumference of the ring body 121 and are located on the ring body 121. In some embodiments, the buckle structure 122 and the ring body 121 are integrally formed by injection molding, thereby improving the connection stability between the buckle structure 122 and the ring body 121. The adapter 120 is snapped with the meter body 110 through the three buckle structures 122. Along the up and down direction of the wireless Internet of Things water meter 100, the ring body 121 is sleeved on the top of the meter body 110, and then snap-connected with the meter body 110 through the buckle structure 122. In some embodiments, the buckle structure 122 is an elastic buckle, and the adapter 120 is snap-connected with the meter body 110 through the elastic buckle. The setting of the elastic buckle is conducive to the disassembly and connection of the adapter 120 and the meter body 110.

[0029] Furthermore, the fixing ring 140 is also arranged around the ring body 121 and abuts against the ring body 121. By abutting the fixing ring 140 against the ring body 121, the fixing ring 140 can support the ring body 121, which is beneficial to improving the anti-deformation ability of the ring body 121. By improving the anti-deformation ability of the ring body 121, the buckle structure 122 connected to the ring body 121 is not easy to deform, thereby improving the stability of the buckle connection between the buckle structure 122 and the watch body 110, and preventing the buckle structure 122 from falling off the watch body 110.

[0030] Furthermore, the fixing ring 140 is in contact with the side of the ring body 121 away from the buckle structure 122, so that the fixing ring 140 is on the outside of the ring body 121. In some embodiments, the buckle structure 122 is on the inside of the ring body 121. During the use of the wireless Internet of Things water meter 100, the wireless Internet of Things water meter 100 will be affected by the force, causing the wireless Internet of Things water meter 100 to shake. During the shaking of the wireless Internet of Things water meter 100, the controller 130 and the meter body 110 will generate a force on the adapter 120 to drive the adapter 120 to deform. At this time, the fixing ring 140 can resist the force generated by the controller 130 and the meter body 110 on the adapter 120, thereby improving the anti-deformation ability of the adapter 120, so that the buckle structure 122 is not affected, and then the buckle structure 122 will not deform and fall off. Through the above arrangement, the connection stability between the buckle structure 122 and the watch body 110 is improved, thereby improving the stability of the buckle connection between the adapter 120 and the watch body 110.

[0031] In the present application, the force applied to the wireless IoT water meter 100 may be the force applied to the wireless IoT water meter 100 by an operator touching the wireless IoT water meter 100, or the force applied to the wireless IoT water meter 100 by the gravity of the controller 130 itself, or the impact force of the medium flowing in the wireless IoT water meter 100 on the wireless IoT water meter 100. The present application does not limit this.

[0032] It should be noted that, in some embodiments, the material strength of the fixing ring 140 may be less than the material strength of the adapter 120, or the material strength of the fixing ring 140 and the adapter 120 may be consistent. For example, the fixing ring 140 and the adapter 120 are both plastic parts. When the wireless IoT water meter 100 is used, the fixing ring 140 is installed so that the fixing ring 140 supports the adapter 120, thereby improving the strength of the adapter 120, thereby improving the deformation resistance of the adapter 120, preventing the buckle structure 122 from deforming and falling off, and improving the connection stability between the buckle structure 122 and the meter body 110.

[0033] In some embodiments, the material strength of the fixing ring 140 can be greater than the material strength of the adapter 120. For example, the fixing ring 140 is an iron ring, and the adapter 120 is a plastic part. When the wireless IoT water meter 100 is used, the fixing ring 140 can support the adapter 120, thereby improving the strength and deformation resistance of the adapter 120. At the same time, the high-strength fixing ring 140 has better deformation resistance, which can further improve the deformation resistance of the adapter 120, thereby further improving the connection stability between the buckle structure 122 and the meter body 110.

[0034] Therefore, the present application does not limit the material of the fixing ring 140 .

[0035] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, as an embodiment, the adapter 120 is provided with an annular groove 123 arranged around the ring body 121, and the fixing ring 140 is located in the annular groove 123 and is clamped with the annular groove 123. Specifically, the central axis of the annular groove 123 extends in the up-down direction, so that the annular groove 123 and the fixing ring 140 are coaxially arranged, which is conducive to the assembly of the fixing ring 140 and the annular groove 123. At the same time, the opening of the annular groove 123 is arranged downward, so that the fixing ring 140 can enter the annular groove 123 from the lower end opening. Among them, one side wall of the annular groove 123 is formed by the surface of the side of the ring body 121 away from the buckle structure 122, so that the fixing ring 140 can abut against the side of the ring body 121 away from the buckle structure 122, so that the fixing ring 140 is located outside the ring body 121. By abutting the fixing ring 140 against the ring body 121, the fixing ring 140 supports the ring body 121, thereby improving the deformation resistance of the ring body 121, and further preventing the snap structure 122 connected to the ring body 121 from being deformed, thereby preventing the snap structure 122 from falling off the watch body 110, and improving the connection stability between the snap structure 122 and the watch body 110.

[0036] Furthermore, by clamping the annular groove 123 and the fixing ring 140 , it is possible to avoid the fixing ring 140 from falling off, thereby improving the connection stability between the fixing ring 140 and the annular groove 123 , thereby improving the supporting stability of the fixing ring 140 on the adapter 120 .

[0037] Specifically, a clamping portion 124 is provided at the opening of the annular groove 123, and the clamping portion 124 at least partially extends toward the ring body 121. The clamping portion 124 is elastic, and in the process of assembling the fixing ring 140 to the annular groove 123, the clamping portion 124 is deformed so that the fixing ring 140 is located in the annular groove 123 after passing through the clamping portion 124. After the fixing ring 140 is assembled to the annular groove 123, the elastic clamping portion 124 can be restored to its initial shape. At this time, the clamping portion 124 can limit the fixing ring 140, thereby preventing the fixing ring 140 from falling off from the annular groove 123, and improving the connection stability between the fixing ring 140 and the annular groove 123.

[0038] The initial shape refers to the shape of the clamping portion 124 in a natural state without deformation.

[0039] Furthermore, the minimum distance between the clamping portion 124 and the ring body 121 along the radial direction of the ring body 121 is a first distance, and the distance between the fixing ring 140 along the radial direction of the ring body 121 is a second distance. When the clamping portion 124 is in the initial shape, the first distance is smaller than the second distance. Through the above arrangement, when the fixing ring 140 is located in the annular groove 123, since the first distance is smaller than the second distance, the fixing ring 140 cannot fall from between the clamping portion 124 and the ring body 121, so that the fixing ring 140 can be stably installed in the annular groove 123, thereby improving the support stability of the fixing ring 140 on the adapter 120.

[0040] It should be noted that the difference between the first distance and the second distance cannot be too small, and the difference between the first distance and the second distance cannot be too large. Specifically, when the difference between the first distance and the second distance is too large, the clamping portion 124 needs to be deformed to a greater extent so that a channel for the fixing ring 140 to enter is formed between the clamping portion 124 and the ring body 140, so that the fixing ring 140 can clamp the clamping portion into the annular clamping groove 123. Due to the large deformation of the clamping portion 124, the clamping portion 124 will break during the deformation process, reducing the service life of the clamping portion 124.

[0041] When the difference between the first distance and the second distance is too small, the contact area between the clamping portion 124 and the fixing ring 140 is small, so that the clamping portion 124 cannot provide sufficient support for the fixing ring 140, causing the clamping portion 124 to lose its limiting effect on the fixing ring 140, and then the fixing ring 140 falls off from the annular groove 123, resulting in poor connection stability between the fixing ring 120 and the annular groove 123.

[0042] Furthermore, when the fixing ring 140 is located in the annular slot 123, the clamping portion 124 abuts against the fixing ring 140, and the clamping portion 124 has a supporting force to support the fixing ring 140. When the clamping portion 124 is in the initial shape, the force exerted on the fixing ring 140 by the clamping portion 124 by the influence of its own gravity is smaller than the supporting force of the clamping portion 124 on the fixing ring 140, so that the clamping portion 124 can provide limited support to the fixing ring 140. Through the above arrangement, during the use of the wireless Internet of Things water meter 100, it is prevented that the fixing ring 140 falls out of the annular slot 123 due to the influence of its own gravity.

[0043] Specifically, when assembling the fixing ring 140, the fixing ring 140 moves upward to open the clamping portion 124, and the clamping portion 124 is deformed under force, so that the distance between the clamping portion 124 and the ring body 121 is greater than or equal to the radial distance of the fixing ring 140 along the ring body 121, so that the fixing ring 140 can smoothly enter the annular groove 123 and abut against the ring body 121, so that the fixing ring 140 supports the ring body 121, and then the fixing ring 140 supports the adapter 120, thereby improving the deformation resistance of the adapter 120, so that the buckle structure 122 does not deform and fall off, and the stability of the buckle connection between the adapter 120 and the watch body 110 is improved. When the fixing ring 140 enters the annular groove 123 , the fixing ring 140 no longer exerts force on the clamping portion 124 , and the clamping portion 124 returns to its original shape, so that the clamping portion 124 limits the fixing ring 140 and prevents the fixing ring 140 from falling out of the annular groove 123 .

[0044] As an embodiment, a first guide angle structure 1241 is provided on the side of the clamping portion 124 away from the bottom of the annular clamping groove 123, and the fixing ring 140 is provided with a second guide angle structure 141 adapted to the first guide angle structure 1241. In this embodiment, the installation direction of the fixing ring 140 is to enter the annular clamping groove 123 from bottom to top, so the second guide angle structure 141 is located at the upper end of the fixing ring 140, and the second guide angle structure 141 is located on the side of the fixing ring 140 away from the watch body 110. Through the provision of the first guide angle structure 1241 and the second guide angle structure 141, when the fixing ring 140 is assembled into the annular clamping groove 123, it is possible to facilitate the fixing ring 140 to open the clamping portion 124 and enter the annular clamping groove 123, thereby avoiding interference between the fixing ring 140 and the clamping portion 124, resulting in the situation that the fixing ring 140 cannot open the clamping portion 124. In addition, when the fixing ring 140 is located in the annular groove 123, the first guide angle structure 1241 of the clamping portion 124 is located on the side away from the fixing ring 140, and the side of the clamping portion 124 close to the fixing ring 140 is basically a plane, thereby increasing the contact area between the clamping portion 124 and the fixing ring 140, which is beneficial to increasing the supporting force of the clamping portion 124 on the fixing ring 140 and avoiding the fixing ring 140 from falling off from the annular groove 123.

[0045] Specifically, when the fixing ring 140 is assembled, the fixing ring 140 opens the clamping portion 124 from the lower end of the annular clamping groove 123, and the second guide angle structure 141 on the fixing ring 140 can abut against the first guide angle structure 1241 on the clamping portion 124. The cooperation of the first guide angle structure 1241 and the second guide angle structure 141 can play a guiding role when the fixing ring 140 and the clamping portion 124 are assembled, so that the fixing ring 140 can smoothly enter the clamping portion 124 and open the clamping portion 124, which is conducive to the deformation of the clamping portion 124 in cooperation with the fixing ring 140, and then the distance between the clamping portion 124 and the ring body 121 is greater than or equal to the radial distance of the fixing ring 140 along the ring body 121, which is conducive to the fixing ring 140 smoothly entering the annular clamping groove 123.

[0046] like Figure 2 and Figure 5 As shown, as an embodiment, the controller 130 is at least partially formed with an extension portion 131, and when the controller 130 is fixed to the adapter 120, the extension portion 131 abuts against a side of the clamping portion 124 away from the fixing ring 140. In some embodiments, along the up-down direction of the wireless IoT water meter 100, the controller 130 is located above the adapter 120, and the extension portion 131 extends downward, so that the extension portion 131 abuts against a side of the clamping portion 124 away from the fixing ring 140, so that the extension portion 131 can support the clamping portion 124. The extension portion 131 supports the side of the clamping portion 124 away from the fixing ring 140, and the fixing ring 140 supports the side of the clamping portion 124 facing the fixing ring 140, so that both sides of the clamping portion 124 can be supported by the support force, thereby improving the anti-deformation ability of the clamping portion 124, and then improving the limiting stability of the clamping portion 124 on the fixing ring 140, preventing the fixing ring 140 from falling off from the annular groove 123, and improving the support stability of the fixing ring 140 on the ring body 121. Therefore, through the above arrangement, the anti-deformation ability of the adapter 120 can be improved, the buckle structure 122 can be prevented from deformation and falling off, and the stability of the buckle connection between the adapter 120 and the watch body 110 can be improved. At the same time, the improvement in the deformation resistance of the clamping portion 124 can enable the clamping portion 124 to withstand a fixing ring 140 with greater mass, which is beneficial for adding a fixing ring 140 with greater strength and mass to the adapter 120, thereby further improving the deformation resistance of the adapter 120 and further improving the stability of the snap connection between the adapter 120 and the watch body 110.

[0047] Furthermore, when the fixing ring 140 is located in the annular groove 123, the fixing ring 140 will exert a force on the clamping portion 124 away from the fixing ring 140 due to its own gravity. When the supporting force of the clamping portion 124 on the fixing ring 140 is less than the force of the fixing ring 140 on the clamping portion 124, the fixing ring 140 will open the clamping portion 124 and fall. Through the provision of the extension portion 131, the extension portion 131 can support the clamping portion 124, thereby improving the supporting force of the clamping portion 124 on the fixing ring 140, avoiding the situation where the fixing ring 140 is pushed downward by its own gravity to open the clamping portion 124 and fall, thereby improving the connection stability between the fixing ring 140 and the annular groove 123 on the adapter 120, so that the fixing ring 140 can stably support the adapter 120, and improving the stability of the adapter 120's anti-deformation ability.

[0048] like Figure 2 As shown, as an embodiment, the watch body 110 also includes a main body 111 and a middle cover 112, and the middle cover 112 is installed on the main body 111 and fixedly connected to the main body 111. In some embodiments, the outer wall of the upper end of the main body 111 is provided with an external thread (not shown in the figure), and the inner wall of the lower end of the middle cover 112 is provided with an internal thread (not shown in the figure) adapted to the external thread, and the main body 111 and the middle cover 112 are threadedly connected through the external thread and the internal thread. At the same time, the adapter 120 is connected to the middle cover 112 through a plurality of snap structures 122, thereby realizing the connection between the adapter 120 and the main body 111.

[0049] like Figure 2 As shown, as an implementation, the wireless IoT water meter 100 further includes a fastener 150, and the controller 130 is fixedly connected to the adapter 120 via the fastener 150. In some embodiments, the fastener 150 is a screw, and the controller 130 is connected to the adapter 120 via the screw. In this way, the screw connection is more stable, which is conducive to improving the connection stability between the controller 130 and the adapter 120, and avoiding the situation where the controller 130 falls off the adapter 120.

[0050] In this application, the assembly process of the wireless Internet of Things water meter 100 is as follows:

[0051] First, the fixing ring 140 is stretched open from the lower end opening of the annular groove 123 to open the clamping part 124, so that the clamping part 124 is deformed, and the distance between the clamping part 124 and the ring body 121 is greater than or equal to the radial distance of the fixing ring 140 along the ring body 121, so that the fixing ring 140 enters the annular groove 123. When the fixing ring 140 enters the annular groove 123, the fixing ring 140 abuts against the ring body 121, so that the fixing ring 140 supports the adapter 120. At the same time, the clamping part 124 returns to its initial shape. So that the clamping part 124 limits the fixing ring 140 to prevent the fixing ring 140 from falling off from the annular groove 123.

[0052] The controller 130 is then fixedly connected to the adapter 120 by screws, and the extension 131 of the adapter 120 abuts against one end of the clamping portion 124 away from the fixing ring 140, so that the extension 131 supports the clamping portion 124. The extension 131 cooperates with the fixing ring 140 to support both sides of the clamping portion 124, thereby improving the anti-deformation ability of the clamping portion 124, preventing the clamping portion 124 from deforming during the use of the wireless Internet of Things water meter 100, thereby preventing the fixing ring 140 from detaching from the annular clamping groove 123 from the deformed clamping portion 124, and improving the support stability of the fixing ring on the annular clamping groove 123.

[0053] Finally, the middle cover 112 is installed on the main body 111, and then the adapter 120 is snap-connected to the middle cover 112 through the snap-fit ​​structure 122 to complete the assembly of the wireless Internet of Things water meter 100.

[0054] During the use of the wireless Internet of Things water meter 100, the support of the adapter 120 by the fixing ring 140 can improve the strength of the adapter 120, thereby improving the deformation resistance of the adapter 120. When affected by external force or the gravity of the controller 130 itself, the adapter 120 is not easily deformed, and the buckle structure 122 will not be deformed, thereby improving the stability of the buckle connection between the adapter 120 and the meter body 110 and avoiding the adapter 120 and the controller 130 from falling off the meter body 110.

[0055] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to this application.
