Referring to fig. 4 and 6, in which the docking member 221 shown in fig. 4 is separated from the second panel shell 222, the docking member 221 shown in fig. 6 is slidably connected to the second housing 2221 along the second direction (i.e. the front in fig. 1, 4 and 6); when the second housing 2221 of the second panel housing 222 and the docking piece 221 form a sliding connection in the second direction, the water meter mounting structure enters the first assembled state. The sliding connection between the second housing 2221 and the docking element 221 may be achieved by a rail-slider mechanism, and according to some embodiments of the present invention, a rail is provided on the second housing 2221, a slider is provided on the docking element 221 and is engaged with the rail, and the second housing 2221 is slid relative to the docking element 221 by the engagement between the rail and the slider.

As a preferred sliding connection, please refer to fig. 6, wherein the docking piece 221 shown in fig. 6 is slidably connected to the second housing 2221 along the second direction and the guiding portion is not shown; the second panel assembly 220 further includes a guide portion, the docking member 221 has a guide groove 225, the second housing 2221 is connected to the guide portion, and in the first assembled state, the second housing 2221 is slidably connected to the docking member 221 through the guide groove 225 and the guide portion; the guide portion and the guide groove 225 extend along the second direction, and the inner wall of the guide groove 225 restricts the guide portion from moving relative to the guide groove 225 in any direction perpendicular to the second direction.

Through the above scheme, at the in-process of installing water gauge mounting structure, only need arrange the guide part in the guide way 225 along the second direction and can form the sliding connection between second face-piece 222 and the butt joint piece 221, the installation is comparatively simple and convenient, and the structure of guide part and guide way 225 is also comparatively simple, is favorable to reducing the space that second face-piece subassembly 220 occupy in the design. According to other embodiments of the present invention, the docking member 221 is connected to the guide portion, and the second housing 2221 has the guide groove 225.

Referring to fig. 1, 4 and 6, the docking piece 221 shown in fig. 6 is slidably connected to the second housing 2221 along the second direction; in the first assembled state, the docking member 221 can move along a first direction (i.e. downward in fig. 1, 4 and 6) and drive the limiting member 230 to enter the limiting groove 240, and is limited in the first direction and any direction perpendicular to the first direction, so that the water meter mounting structure enters a second assembled state, and the second direction is perpendicular to the first direction.

Referring to fig. 1, 4 and 5, the limiting member 230 and the limiting groove 240 are used for limiting the distance between the docking member 221 and the first panel assembly 210, that is, the first panel assembly 210 can prevent the docking member 221 from moving along the first direction and any direction perpendicular to the first direction by the cooperation between the limiting member 230 and the limiting groove 240; according to some embodiments of the present invention, the limiting member 230 is connected to the docking member 221, the first panel assembly 210 is provided with a limiting groove 240, and the limiting member 230 is shown in the second figure to be located directly above the limiting groove 240; the abutting part 221 moves along the first direction to drive the limiting part 230 to synchronously move along the first direction, and finally the limiting part 230 is accommodated in the limiting groove 240.

In order to enable the limiting member 230 and the limiting groove 240 to limit each other, according to some embodiments of the present invention, the limiting member 230 connected to the docking member 221 is a prism extending along the first direction, and the shape of the inner wall of the limiting groove 240 on the first panel assembly 210 is a prism hole matching the shape of the limiting member 230; according to other embodiments of the present invention, the limiting member 230 is a cylinder, and the projection of the limiting member 230 along the first direction is a polygon, and the shape of the inner wall of the limiting groove 240 is a polygonal hole matching the shape of the limiting member 230; according to other embodiments of the present invention, the face housing 200 includes a plurality of stoppers 230, and the plurality of stoppers 230 are engaged with a stopper groove 240. The limiting member 230 may be other shaped structures and the limiting groove 240 may be any shape capable of limiting the movement of the shaped structure in the first direction and any direction perpendicular to the first direction without departing from the spirit of the present invention.

When the docking member 221 moves along the first direction, the limiting member 230 enters the limiting groove 240, and the docking member 221 is slidably connected to the second housing 2221 of the second panel shell 222 when moving along the first direction, so as to drive the second panel shell 222 to move along the first direction together, and limit the second panel shell 222 to move along any direction other than the direction perpendicular to the second direction relative to the docking member 221.

Referring to fig. 1,2, 6, and 9, in the second assembled state, the limiting member 230 is received in the limiting groove 240, the first reference plane 2211 faces the first direction (i.e. the upper direction shown in fig. 1,2, 6, and 9), the second reference plane faces the first direction, and the first reference plane 2211 abuts against the second reference plane; the second housing 2221 is capable of sliding along the second direction relative to the docking element 221 and driving the first plug portion 2222 to insert into the first panel assembly 210 so as to bring the water meter mounting structure into the third assembly state.

Since the first reference plane 2211 of the docking member 221 abuts against the second reference plane of the second housing 2221, and the first reference plane 2211 is reversed in the first direction, when the second panel shell 222 is restrained from being moved in the first direction, the second panel shell 222 can restrict the reversed movement of the docking member 221 in the first direction by the abutting relationship of the first reference plane 2211 and the second reference plane.

In order to further stabilize the movement of the second housing 2221 in the second direction in the second assembled state. Further, referring to fig. 1,2, 6, 9, 10, and 11, in some embodiments, the first panel assembly 210 has a travel slot 212, and the travel slot 212 extends along the second direction; the second panel shell 222 further includes a second plug portion 2223, where the second plug portion 2223 is connected to the second housing 2221; in the first assembled state, the second plug portion 2223 can be inserted into the travel groove 212 along the first direction, and the inner wall of the travel groove 212 limits the second plug portion 2223 to move in the fourth direction relative to the first panel assembly 210, and the fourth direction, the second direction and the first direction are perpendicular to each other. Through the above scheme, the inner wall of the travel groove 212 can limit the movement of the second housing 2221 connected with the second plug portion 2223 along the fourth direction through the second plug portion 2223, so as to reduce the deformation of the portion of the second housing 2221 connected with the second plug portion 2223 relative to other portions, further enhance the strength of the whole second housing 2221 in the second assembly state, make the second housing 2221 more stable when moving along the second direction, and facilitate the first plug portion 2222 connected with the second housing 2221 to be inserted into the first panel assembly 210.

Since the second panel shell 222 and the docking member 221 are both maintained in the sliding connection relationship in the second direction in the first assembled state and the second assembled state, a person skilled in the art can automatically adjust the slidable distance between the second panel shell 222 and the docking member 221 in the second direction without performing any inventive work, and automatically adjust the distance between the docking member 221 and the second panel shell 222 when the docking member 221 moves in the first direction, so that the second panel shell 222 and the docking member 221 can move in the first direction while maintaining the predetermined distance when the water meter mounting structure is in the first assembled state, the water meter mounting structure can be brought into the second assembled state, and the second housing 2221 can be moved in the second direction and the first plugging portion 2222 can be driven to be plugged into the first panel shell assembly 210 in the second assembled state.

In the actual installation process, since the second panel shell 222 and the docking member 221 are both in a sliding connection relationship in the first assembly state and the second assembly state, a worker cannot easily adjust the distance between the docking member 221 and the second panel shell 222 to a preset distance in the process of freehand operation, so that the structure on the second panel shell 222 interferes with the structure on the first panel shell assembly 210 in the process of aligning the limiting member 230 with the limiting slot 240, for example, the first plugging portion 2222 may interfere with the first panel shell assembly 210 due to the fact that the distance between the docking member 221 and the second panel shell 222 is smaller than the preset distance. Although the worker can adjust the docking member 221 and the second panel case 222 to a preset distance through a limited number of adjustments, the above-described process is inefficient in installation and is prone to wear on the docking member 221 and the second panel case 222 during repeated adjustments, thereby reducing the quality of the water meter installation structure.

Further, referring to fig. 1,2, 6 and 7, in some embodiments, the second housing assembly 220 includes a protrusion 223, the protrusion 223 has elasticity, one of the docking member 221 and the second housing 2221 has a receiving groove 224, and the other of the docking member 221 and the second housing 2221 is connected to the protrusion 223, and the water meter mounting structure has a pre-assembled state.

In the first assembled state, the receiving groove 224 can receive the boss 223, thereby restricting the interval between the docking member 221 and the second housing 2221 in the first direction to bring the water meter mounting structure into the pre-assembled state.

In the pre-assembled state, referring to fig. 7, the docking member 221 can move along the first direction and drive the limiting member 230 to enter the limiting groove 240, and is limited in the direction perpendicular to the first direction, so that the water meter mounting structure enters the second assembled state; in the second assembled state, the protruding portion 223 can withdraw from the accommodating groove 224, so that the second housing 2221 can slide along the second direction relative to the docking element 221 and drive the first inserting portion 2222 to insert into the first panel assembly 210.

Through the above scheme, the accommodating groove 224 and the protruding portion 223 in the pre-assembled state directly enable the second housing 2221 and the docking piece 221 to be kept relatively fixed at a preset distance, so that the adjustment process of the docking piece 221 and the second face housing 222 by workers is omitted, and the installation efficiency is improved. On the other hand, since the boss 223 has elasticity, the boss 223 can be withdrawn from the accommodating groove 224 in the second assembled state, so that the boss 223 and the accommodating groove 224 do not affect the movement of the second housing 2221 relative to the docking element 221 in the second direction, and the worker can continue with the subsequent mounting step.

From a design point of view, since the abutting piece 221 can determine the distance from the second casing 222 through the protruding portion 223 and the receiving groove 224, the structural dimension on the second casing 222 can be further adjusted at the above distance, thereby enhancing the assembly accuracy of the entire water meter mounting structure.

For specific operation of the boss 223 and the receiving groove 224, refer to fig. 7, 8, and 9, wherein fig. 7 is a schematic view of the water meter mounting structure in a pre-assembled state, and according to some embodiments of the present invention, the second housing 2221 has the receiving groove 224, and the docking member 221 is connected to the boss 223; the boss 223 is protruded in a reverse direction of the first direction with respect to the docking member 221, the accommodating groove 224 is recessed in a reverse direction of the first direction with respect to the second housing 2221, and when the water meter mounting structure is in the first assembled state, the second housing 2221 is slidable in the second direction with respect to the docking member 221, and the boss 223 is located at one side of the accommodating groove 224 in the second direction and is in a deformed state by pressure of the second housing 2221; the second panel shell 222 moves along the second direction relative to the abutting piece 221, the distance between the protruding portion 223 and the accommodating groove 224 in the second direction is continuously reduced to 0, the interval between the second panel shell 222 and the abutting piece 221 becomes a preset distance, the protruding portion 223 in the deformed state is not pressed by the second shell 2221 and extends into the accommodating groove 224, and therefore the second panel shell 222 is limited to further move along the second direction through abutting with the inner wall of the accommodating groove 224, and the water meter installation structure enters a pre-assembled state.

In the above process, the operator who performs the operation can also sense that the water meter has entered the pre-assembled state from the acting force between the protruding portion 223 and the inner wall of the receiving groove 224, and can continuously align the limiting member 230 with the limiting groove 240 and install the abutting member 221, so that the water meter installation structure enters the second assembled state. In the second assembled state, the worker can increase the force of moving the second housing 2221 to bring the boss 223 into the deformed state again, so that the second panel shell 222 can be moved in the second direction with respect to the docking piece 221, and the subsequent mounting step is performed.

The foregoing has described the embodiment in which the first housing assembly 210 restricts the second insertion portion 2223 of the second housing 2221 by the travel groove 212, and based on the above-described embodiment, a person skilled in the art can adjust the positional relationship between the boss 223 and the receiving groove 224 without performing inventive work, so that the second insertion portion 2223 can be inserted into the travel groove 212 in the first direction when the boss 223 is received in the receiving groove 224.

Referring to fig. 1,3 and 9, in the third assembled state, the first housing assembly 210 limits the first plugging portion 2222 to move relative to the first housing assembly 210 in any direction perpendicular to the second direction, and the second housing 222 can be plugged into the first housing assembly 210 along the third direction (i.e. the lower direction in fig. 1,3 and 9) by the plug 300, so that the water meter installation structure enters the assembled state, and the third direction is perpendicular to the second direction.

Since the first housing assembly 210 restricts the movement of the first plug portion 2222 connected to the second housing 2221 relative to the first housing assembly 210 in any direction perpendicular to the second direction, the second housing 222 is directly restricted by the first housing assembly 210; and it has been described above that the second panel assembly 220 can restrict the opposite movement of the abutment 221 in the first direction by the abutting relationship of the first reference plane 2211 and the second reference plane, the movement of the abutment 221 in all directions is restricted by the first panel assembly 210 and the second panel assembly 220. In the third assembled state, the second panel 222 is only movable relative to the first panel assembly 210 in the second direction and in a direction opposite to the second direction; after the second casing 222 is plugged into the first casing assembly 210 along the third direction by the docking member 221, the movement of the second casing 222 along all directions is also limited by the first casing assembly 210 by the plugging member 300, and the water meter installation structure enters the assembled state.

In the assembled state, the connector 300 restricts the relative movement of the second panel 222 and the first panel assembly 210 in the second direction, so that the connector 221 of the second panel assembly 220 and the second panel 222 are completely fixed to the first panel assembly 210.

The above has been described as a solution for fixing the relative positions of the second housing 2221 and the docking element 221 by providing the boss 223 and the receiving groove 224. On the basis of the above-described arrangement, please refer to fig. 7, fig. 8, wherein fig. 8 shows the positional relationship of the docking member 221 and the second housing 2221 in the second direction in the assembled state; according to some embodiments of the present invention, the second housing 2221 has a receiving groove 224, and the docking member 221 is connected to the boss 223; the boss 223 is protruded in a reverse direction of the first direction with respect to the docking 221, the receiving groove 224 is recessed in a reverse direction of the first direction with respect to the second housing 2221, and the second housing 2221 is further provided with a receiving chamber 226 therein. Through the above scheme, under the assembly completion state, the bellying 223 holds in holding the chamber 226, and bellying 223 can resume under the deformation state to avoid bellying 223 to continue extrusion butt joint piece 221 and second casing 2221, strengthen water gauge mounting structure's durability. A person skilled in the art may also provide the boss 223 on the second housing 2221 and the receiving groove 224 and the receiving cavity 226 on the docking piece 221 without departing from the inventive concept.

For the specific form of the first panel assembly 210 being plugged to the second panel assembly 220 by the plug 300, those skilled in the art can use conventional pins; as a preferred embodiment, referring to fig. 12 and 13, the first panel assembly 210 has a positioning hole 211, and the positioning hole 211 penetrates the first panel assembly 210 along a third direction; the second housing 2221 has a positioning groove 2221a extending in the third direction, the positioning groove 2221a being provided with an opening on one side in the third direction; in the third assembled state, the opening communicates with the positioning hole 211; in the assembled state, the connector 300 is inserted into the positioning groove 2221a and the positioning hole 211. Through the above, in addition to being able to restrict the movement of the second panel 222 by the connector 300, the connector 300 can be inserted into the positioning hole 211 from the positioning groove 2221a in the second housing 2221 during the installation process, since the positioning hole 211 penetrates the first panel assembly 210 in the third direction.

As a preferred solution, in the third assembled state, one side of the second housing 2221 in the second direction abuts against the first panel assembly 210, which is advantageous in that the positioning hole 211 is confirmed to be already in communication with the positioning groove 2221a by abutment of the second housing 2221 and the first panel assembly 210, thereby simplifying the installation process.

Further, referring to fig. 12 and 13, in some embodiments, the plug 300 includes a shaft 310 and a positioning portion 320, where the positioning portion 320 is connected to a radial direction of the shaft 310; in the assembled state, the positioning portion 320 abuts against the first panel assembly 210 at one side in the third direction. Through the above scheme, in the process that the plug 300 located in the positioning groove 2221a extends into the positioning hole 211, the abutting relationship between one side of the positioning portion 320 in the third direction and the first panel assembly 210 can be accommodated in the positioning groove 2221a, and only a part of the shaft body 310 extends into the positioning hole 211, so that the plug 300 is prevented from being separated from the first panel assembly 210 and the second panel assembly 220.

Further, referring to fig. 12 and 13, in some embodiments, the water meter mounting structure further includes a return spring 400, the return spring 400 is sleeved on the shaft body 310, one end of the return spring 400 is connected to the inner wall of the positioning slot 2221a, and the other end of the return spring 400 abuts against one side of the positioning portion 320 in the opposite direction of the third direction. Through the above scheme, the reset spring 400 can continuously apply force along the third direction to the plug 300, so as to prevent the shaft body 310 from being reversely separated from the positioning hole 211 along the third direction; on the other hand, in the installation process, since the reset spring 400 continuously extrudes the plug 300, when the opening of the positioning groove 2221a is communicated with the positioning hole 211, the plug 300 is extruded by the reset spring 400 and automatically extends out of the positioning hole 211, so that the process that a worker withdraws the plug 300 from the positioning groove 2221a is omitted, and the installation efficiency is improved.
