Description

Technical Field

[0001] The utility model belongs to the technical field of flow meters and relates to an installation structure of a water meter signal module. Background Technique

[0002] Water meters are very common in today's life. They are mainly installed in combination with water supply pipelines to accurately measure the water consumption of each household and provide a scientific and reasonable charging basis for management personnel. They are an indispensable metering device in the prior art.

[0003] With the continuous development of technology, the types of water meters are becoming more and more diverse. A water meter with wireless receiving and transmitting functions is a relatively popular one in the current market. Specifically, it generally includes a housing for connecting pipelines, a counter installed on the housing for measuring water consumption, an outer cover installed on the housing and covering the counter therein, and a signal module installed on the outer cover. The signal module generally includes structures such as a circuit board, a battery, an antenna, a signal receiver, a signal transmitter, etc. These components are integrated in a housing, and the housing is installed on the outer cover of the water meter by screwing with screws. The water consumption signal is obtained through a signal processing device and transmitted to the terminal for recording, achieving the function of real-time monitoring of water consumption, thereby reducing the burden of meter reading work for management personnel.

[0004] There are various working methods for the signal module. For example, a water meter remote meter reading device disclosed in Chinese Patent Application No. 202222055572.2 takes pictures of the numbers on the meter through a camera head and feeds back data to the terminal. And as an alternative solution, a magnet may also be installed on the impeller in the housing, and the signal processing device measures the water consumption in a magnetic induction cooperation manner through a Hall sensor and the magnet.

[0005] However, the space for installing the water meter itself is relatively narrow. Especially after integrating the signal module, more precise control of space utilization is required, which makes the installation position of the signal module relative to the outer cover very precise. Currently, the installation of the signal module generally involves directly placing the housing on the meter cover and then tightening it with screws. However, this is very likely to cause a certain deflection of the installation position of the meter cover relative to the predetermined position, and assembly personnel need to repeatedly debug to reduce its deflection amount to within the allowable tolerance range, which is very inconvenient to operate. Summary of the Invention

[0006] The purpose of the utility model is to propose an installation structure of a water meter signal module for the existing technology with the above problems. The technical problem to be solved by the utility model is: how to improve the assembly efficiency on the premise of ensuring the installation position of the signal module.

[0007] The object of the present utility model can be achieved by the following technical solutions: An installation structure of a water meter signal module, including a counter, an installation shell, and an outer cover covering the counter. It is characterized in that a protruding portion is provided on the outer wall of the top of the outer cover, an annular convex portion is provided on the inner wall of the top of the outer cover directly below the protruding portion, and an observation port is provided on the top of the outer cover on one side of the protruding portion and the annular convex portion. A limiting groove is provided on the counter directly below the annular convex portion, and a limiting rib is further provided on the counter within the observation port. A first positioning groove and a second positioning groove are provided at the bottom of the installation shell. The annular convex portion is embedded and limited within the limiting groove, the installation shell and the outer cover are detachably connected by fasteners, the protruding portion is embedded and limited within the first positioning groove, and the limiting rib is embedded and limited within the second positioning groove.

[0008] The assembly principle of the installation structure of this water meter signal module is as follows: Cover the outer cover on the counter, and perform pre-positioning of the installation through the annular convex portion on the inner wall of the top of the outer cover and the limiting groove provided on the top of the counter in a snap-fit manner. On the premise of ensuring the firm connection between the two, screw the outer cover and the shell of the installation structure of the water meter signal module tightly with screws, and make the digit wheels on the counter located within the observation port provided on the outer cover. Then place the installation shell on the outer cover. The installation shell is specifically used for mounting components. By installing components such as a circuit board, a battery, an antenna, a signal receiver, and a signal transmitter inside it, a complete signal processor is formed. A first positioning groove and a second positioning groove are respectively provided at the bottom of the installation shell, and a limiting rib located within the observation port is provided on the outer wall of the top of the counter. When the installation shell is placed on the outer cover, the protruding portion can be directly snapped into the first positioning groove, and at the same time, the limiting rib is snapped into the second positioning groove. Through two-point positioning, the rapid assembly pre-positioning of the installation shell is realized, and it is ensured that the installation position of the installation shell can always be maintained at an ideal installation position, without worrying about the position of the installation shell shifting during the subsequent assembly process. While ensuring the accurate installation position, a higher installation efficiency is ensured. In addition, such assembly can also ensure that the installation shell has a connection relationship with the meter cover and the counter, ensuring higher installation stability. It is worth mentioning that the specific fixing method of the installation shell is: A through hole penetrating the inner bottom wall of the annular convex portion is provided on the protruding portion, and a nut is installed in the annular convex portion in a snap-fit manner. An installation channel penetrating the upper and lower surfaces of the installation shell is provided inside the installation shell, and the lower end of the installation channel penetrates the inner wall of the first positioning groove. A bolt is inserted successively into the installation channel, the first positioning groove, the through hole of the protruding portion, and the annular convex portion and screwed with the nut, so that the installation shell is pressed tightly on the outer cover, and the outer cover itself is screwed and locked with the shell of the installation structure of the water meter signal module by bolts, thus ensuring the firm installation of the installation shell.

[0009] In the installation structure of the above-mentioned water meter signal module, the protruding part, the first positioning groove, and the annular convex part have the same shape, which is a regular hexagon. This ensures that the nut installed subsequently can be firmly positioned in the annular convex part, effectively preventing the outer cover from rotating. At the same time, when the protruding part is embedded in the first positioning groove, it can also limit the rotation of the installation shell, thereby avoiding the situation where the installation shell deflects in position when in the pre-positioning state.

[0010] In the installation structure of the above-mentioned water meter signal module, there is also a strip-shaped positioning rib on the outer wall of the top of the outer cover, and a third positioning groove is also opened at the bottom of the installation shell. The positioning rib is embedded and limited in the third positioning groove. When the protruding part on the top of the outer cover is embedded in the first positioning groove at the bottom of the installation shell, at this time, the positioning rib on the outer wall of the top of the outer cover is also embedded in the third positioning groove opened at the bottom of the installation shell, thereby further ensuring that the pre-positioning between the installation shell and the outer cover is more firm and reliable. And because the positions of the first positioning groove and the protruding part remain relatively unchanged, and the positions of the third positioning groove and the positioning rib also remain relatively unchanged, it is ensured that the installation can be in place at one time, and there is no need to repeatedly debug the position of the installation shell during the installation process.

[0011] In the installation structure of the above-mentioned water meter signal module, there is also a clamping block near the edge of the outer wall of the top of the outer cover. There is a bayonet on the clamping block. A fourth positioning groove is opened on the outer wall of one side of the installation shell, and there is a clamping block on the groove wall of the fourth positioning groove. The clamping block is embedded in the fourth positioning groove and the clamping block is engaged with the bayonet. On the basis of the foregoing solution, during the pre-fixing process of assembling the installation shell, the connection between the installation shell and the outer cover is further improved through the clamping cooperation of the clamping block and the fourth positioning groove and the clamping block and the bayonet.

[0012] In the installation structure of the above-mentioned water meter signal module, the counter has a protruding clamping part, and the clamping part is embedded and limited in the observation port. Through this setting, the counter and the outer cover can be quickly assembled. After the assembly is completed, there is no need to rotate the outer cover to adjust the orientation of the observation port, and it can also ensure that the pre-positioning of the outer cover is more firm.

[0013] Compared with the prior art, the installation structure of this water meter signal module has the following advantages:

[0014] 1. Through the clamping cooperation of the protruding part and the first positioning groove, and the clamping cooperation of the second positioning groove and the limiting rib, the installation shell has positioning points with the outer cover and the counter respectively. Assemblers can avoid the installation position from shifting when in the pre-positioning state through the two-point positioning method, thereby preventing the need for repeated position adjustment before locking with fasteners subsequently, and ensuring more efficient assembly.

[0015] 2. By the snap - fit cooperation of the positioning rib and the third positioning groove, and the snap - fit cooperation of the fourth snap - block and the fourth positioning groove, the pre - positioning of the installation shell during installation is ensured to be more reliable.

[0026] The following are specific embodiments of the present invention and in combination with the attached drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0027] Such as Figures 1-3As shown, the installation structure of the water meter signal module includes a counter 1, an installation shell 2, and an outer cover 3. The counter 1 is installed on the water meter housing for real-time monitoring of water consumption. The outer cover 3 covers the counter 1 and is screwed and locked to the water meter housing by fasteners to ensure sufficient protection for the counter 1. The installation shell 2 is the main body part for carrying the signal module, and parts such as a circuit board, a battery, an antenna, a signal receiver, and a signal transmitter are installed inside it. It is used to record the values counted by the counter 1 and transmit data to a computer terminal.

[0028] Combined with Figure 5 and Figure 9 , on the inner wall of the top of the outer cover 3, there is an annular convex part 32, and its contour is specifically hexagonal. The counter 1 specifically includes a bottom shell, a wheel assembly installed in the bottom shell, a cover plate covering the wheel assembly, and a glass panel fixed to the top of the bottom shell. It is worth mentioning that near the edge of the bottom surface of the glass panel, there is a convex part, and a combination groove is opened on the convex part. A notch is opened on one side edge of the cover plate. A clamping post is provided between the glass panel and the cover plate. The upper end of the clamping post is clamped in the notch, and a hook connection part protrudes from the outer wall of one side of the lower end. The lower end of the clamping post passes through the notch and hooks the bottom surface of the cover plate through the hook connection part. When assembling and producing the counter 1, the glass panel and the cover plate can be assembled first, and then the glass panel is pressed onto the bottom shell by a machine. The firmness of the cover plate installed in the bottom shell is ensured by the locking force between the glass panel and the inner wall of the bottom shell in the axial direction.

[0029] Combined with Figure 8 , on the top of the counter 1 (i.e., on the upper side of the glass panel), there is a clamping part 13 protruding upward. On the top of the counter 1 (i.e., on the upper side of the glass panel), there is also a limit groove 11 located on one side of the clamping part 13 and with a hexagonal contour. An observation port 33 is opened on the outer cover 3 on one side of the annular convex part 32. When the outer cover 3 covers the counter 1, the clamping part 13 is embedded and positioned in the observation port 33, and at the same time, the annular convex part 32 is also embedded and positioned in the limit groove 11, so that the outer cover 3 maintains stable installation through two positioning points, and then is screwed and locked to the water meter housing by screws, thus ensuring its installation firmness.

[0030] Combined with Figure 6 and Figure 7, on the top outer wall of the outer cover 3, there is a protruding part 31 located directly above the annular convex part 32 and in the shape of a hexagon. On the top of the counter 1 (i.e., on the upper side of the glass panel), there is a limiting rib 12. At the bottom of the mounting shell 2, a first positioning groove 21 and a second positioning groove 22 are provided. The shape of the first positioning groove 21 is the same as that of the protruding part 31, and the shape of the second positioning groove 22 is the same as that of the limiting rib 12. During assembly, the mounting shell 2 is placed on the top of the outer cover 3. At this time, the protruding part 31 can be embedded and limited in the first positioning groove 21, and the limiting rib 12 can be embedded and limited in the second positioning groove 22. In addition, on the top of the outer cover 3, there is a positioning rib 34 adjacent to the protruding part 31 and in the shape of a long strip, and a clamping block 35 is provided near the edge of the top outer wall of the outer cover 3. On the side of the clamping block 35 facing away from the edge of the outer cover 3, a bayonet 351 is provided. At the bottom of the mounting shell 2, a long-strip-shaped third positioning groove 23 is provided. At the lower edge of one side surface of the mounting shell 2, a fourth positioning groove 24 is provided. On the bottom wall of the fourth positioning groove 24, there is a clamping block 241. When assembling the mounting shell 2, while the protruding part 31 is clamped with the first positioning groove 21 and the limiting rib 12 is clamped with the second positioning groove 22, the positioning rib 34 can be embedded and limited in the third positioning groove 23, and at the same time, the clamping block 35 can be embedded and limited in the fourth positioning groove 24, and the clamping block 241 in the fourth positioning groove 24 can be clamped with the bayonet 351 on the clamping block 35, so as to ensure the firmness of the pre-positioning of the mounting shell 2.

[0031] Based on the above solution and combined with Figure 4 , the subsequent locking and positioning method for the mounting shell 2 is as follows: A through hole is provided on the protruding part 31, which penetrates the inner bottom wall of the annular convex part 32. At the same time, a nut is installed in the annular convex part 32 in a clamping manner. An installation channel penetrating the upper and lower surfaces of the mounting shell 2 is provided inside the mounting shell 2, and the lower end of the installation channel penetrates the inner wall of the first positioning groove 21. A bolt is inserted into the installation channel, the first positioning groove 21, the through hole of the protruding part 31, and the annular convex part 32 in sequence and screwed with the nut, so that the mounting shell 2 is pressed tightly on the outer cover 3.
