Description
Technical Field
[0001] The utility model belongs to the technical field of water meters and relates to a battery compartment cover structure of a water meter. Background Art
[0002] Water meters are essential water consumption measuring devices for every household in today's life. In recent years, with the continuous development of technology, the popularity of smart water meters has become increasingly higher. As the name suggests, smart water meters are more intelligent and have more diverse functions than traditional water meters. Smart water meters in the existing technology generally require power support, so a battery compartment is set on the cover of the water meter. The battery is installed in the battery compartment and encapsulated by the compartment cover, and the battery supplies energy to each module through the copper sheet in the battery compartment and the preset circuit assembly in the cover.
[0003] However, water meters are currently generally installed in relatively humid environments. Although the battery compartment cover seals the battery compartment, there will inevitably be a certain gap between the two. After long-term use, humid air will enter the battery compartment through the gap and corrode structures such as the battery and copper sheet, which can easily cause a battery short circuit and rust of the copper sheet (which will cause the copper sheet's conductivity to deteriorate and easily cause poor contact). Summary of the invention
[0004] The purpose of the utility model is to solve the above problems in the prior art and to propose a battery compartment cover structure for a water meter. The technical problem to be solved by the utility model is: how to improve the sealing effect of the battery compartment.
[0005] The objectives of the utility model can be achieved through the following technical solutions: a battery compartment cover structure of a water meter, the water meter includes a meter cover with a battery compartment, the battery compartment cover structure includes a sealing ring and a cover body detachably connected to the meter cover and sealing the battery compartment opening, characterized in that the circumferential inner wall of the battery compartment has a first abutment edge and a second abutment edge spaced along the axial direction of the battery compartment, and the circumferential inner side wall of the battery compartment located between the first abutment edge and the second abutment edge is a sealing surface, the outer end of the cover body has a retaining edge opposite to the first abutment edge along the circumferential direction, the retaining edge abuts against the first abutment edge, the inner end of the cover body abuts against the second abutment edge, and the sealing ring is positioned outside the cover body along the circumferential direction of the cover body and pressed tightly against the sealing surface.
[0006] Compared with the prior art, the advantage of the battery compartment cover structure of the water meter is that: during assembly, the cover body is inserted into the opening of the battery compartment by plugging, so as to preliminarily seal the opening of the battery compartment, and on this basis, the inner end of the cover body directly abuts against the second abutting edge circumferentially arranged on the inner wall of the battery compartment, and the blocking edge at the outer end of the cover body directly abuts against the first abutting edge circumferentially arranged on the inner wall of the battery compartment. Through this arrangement, the contact area between the outer wall of the cover body and the inner wall of the battery compartment is larger, and the gap formed between the two is more tortuous. In addition, the sealing ring installed on the outer wall of the cover body enables the sealing ring to be tightly pressed against the sealing surface in the battery compartment when the assembly is completed, thereby preventing external water vapor from penetrating into the battery compartment through the gap between the outer wall of the cover body and the inner wall of the battery compartment during subsequent operation of the water meter, effectively improving the sealing effect of the battery compartment.
[0007] In the battery compartment cover structure of the water meter described above, a limiting groove is provided on the outer side wall of the cover body in the circumferential direction, and the sealing ring is clamped in the limiting groove. In this way, the limiting effect of the sealing ring is achieved, and the sealing ring is prevented from being irregularly deformed due to strong extrusion force when the cover body is installed, and the actual sealing effect of the sealing ring is effectively guaranteed. As a further optimization scheme, the number of limiting grooves can be several, and several sealing grooves are arranged at intervals along the axial direction of the cover body, and a sealing ring is installed in each sealing groove to ensure a better sealing effect.
[0008] In the battery compartment cover structure of the water meter, the bottom wall of the limiting groove and the inner walls on both sides of the limiting groove form an arc transition. This ensures that when the cover is installed, the sealing ring will first deform toward the inside of the sealing groove when it undergoes elastic deformation. After the sealing groove is filled, the arc transition between the bottom wall of the groove and the inner wall of the groove can provide a buffering effect for the sealing ring, preventing the sealing ring from cracking in the limiting groove due to long-term extrusion.
[0009] In the battery compartment cover structure of the water meter described above, the inner edge of the abutting edge 1 has a beveled guide edge along the circumferential direction. When the cover is installed, the guide edge can guide the sealing ring, so that when the sealing ring transitions from the abutting edge 1 to the sealing surface, the contact amount between the sealing ring and the abutting edge 1 as a whole is reduced, and elastic deformation occurs only when the sealing ring is completely in contact with the sealing surface due to the existence of the extrusion force, thereby ensuring that the outer wall of the sealing ring as a whole is in more complete contact with the sealing surface, thereby ensuring the sealing of the battery compartment.
[0010] In the battery compartment cover structure of the water meter described above, the inner end of the cover body has a protruding block, and the abutting edge has a positioning groove, and the protruding block is embedded and positioned in the positioning groove. The plug-in cooperation between the protruding block and the positioning groove can ensure that the cover body is limited in the circumferential direction, avoiding irregular deformation of the sealing ring caused by the rotation of the cover body, thereby preventing the occurrence of sealing failure.
[0011] In the battery compartment cover structure of the water meter, the notch of the positioning groove is expanded, which plays a guiding role and ensures that the cover body can be quickly assembled in place under the guiding role.
[0012] In the battery compartment cover structure of the water meter, when the blocking edge abuts against the abutting edge, the inner end of the cover body abuts against the abutting edge, and the protruding block is embedded in the positioning groove, the outer end surface of the cover body is flush with the battery compartment port, thereby achieving the function of hiding the cover body, preventing the cover body from protruding too much relative to the outer cover, and preventing the cover body from being damaged by impact from foreign objects.
[0013] Compared with the prior art, the battery compartment cover structure of the water meter has the following advantages:
[0014] 1. The inner end of the cover body abuts against the second abutting edge, the outer end of the retaining edge abuts against the first abutting edge, and the sealing ring abuts against the sealing surface, thereby ensuring that the cover body is stably installed and the gap between the cover body and the battery compartment opening is sealed, thereby ensuring the sealing of the battery compartment.
[0015] 2. After the cover is assembled, its outer end surface is flush with the battery compartment opening, thereby hiding the cover and effectively preventing the cover from being hit. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0025] like Figure 1 As shown, in the battery compartment cover structure of the water meter, the water meter includes a meter cover 1 with a battery compartment 11, and the battery compartment cover structure includes a sealing ring 2 and a cover body 3 detachably connected to the meter cover 1 and sealing the battery compartment 11, Figure 2-4 The inner wall of the battery compartment 11 has a first abutting edge 111 and a second abutting edge 112 along the circumferential direction, the width of the first abutting edge 111 is smaller than the width of the second abutting edge 112, and the first abutting edge 111 and the second abutting edge 112 are arranged at intervals along the circumferential direction of the battery compartment 11, and a sealing surface 4 is formed on the inner wall between the first abutting edge 111 and the second abutting edge 112 in the battery compartment 11, combined with Figure 5-7 The outer end of the cover body 3 has a retaining edge 31 arranged opposite to the abutting edge 111 along the circumferential direction. When assembling the two, the user can insert the cover body 3 into the battery compartment 11 through the compartment opening of the battery compartment 11, so that the inner end of the cover body 3 is in abutment with the surface of the abutting edge 112, and the retaining edge 31 is in abutment with the abutting edge 111. The outer wall of the cover body 3 has at least two limiting grooves 32 distributed along the axial direction of the cover body 3 at intervals. A sealing ring 2 is assembled in each limiting groove 32 by a snap-fitting manner. During the aforementioned installation steps, each sealing ring 2 can be squeezed by the sealing surface 4 to produce elastic deformation, and at the same time, it can be pressed against the sealing surface 4, so as to achieve the purpose of completely blocking the gap between the cover body 3 and the inner wall of the battery compartment 11.
[0026] like Figure 3 As shown, a beveled guide edge 1111 is formed by circumferential grinding at the inner edge of the abutment edge 111. In addition, a rectangular protruding block 33 is injection-molded on the outer wall of the inner end of the cover body 3. At the same time, a positioning groove 1121 corresponding to the position of the protruding block 33 is opened on the abutment edge 112 in the battery compartment 11. The inner walls on both sides of the notch of the positioning groove 1121 are inclined outwardly so that the notch of the positioning groove 1121 is expanded. During assembly, the protruding block 33 can be embedded in the positioning groove 1121 through the guidance of the inner wall at the notch of the positioning groove 1121, ensuring that the cover body 3 is firmly positioned on the watch cover 1 and the opening of the battery compartment 11 is sealed. At the same time, in this state, the outer end face of the cover body 3 can be flush with the opening of the battery compartment 11.
[0027] As a further preferred solution, the battery compartment 11 on the watch cover 1 can be configured to be through-type at both ends, and covers 3 are installed at both ends of the battery compartment 11, so as to facilitate subsequent disassembly and assembly of the battery in a narrow space.
[0028] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0029] Although the terms such as watch cover 1, battery compartment 11, abutting edge 111, guide edge 1111, abutting edge 2 112, positioning groove 1121, sealing ring 2, cover body 3, retaining edge 31, limiting groove 32, protruding block 33, sealing surface 4 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
