Description

Technical Field

[0001] The utility model belongs to the field of shower equipment, and in particular relates to a mounting structure of a shower switch metering component. Background Art

[0002] The existing ordinary showers are generally stainless steel kits without flow metering and electric opening and closing. They have a simple structure and adopt the form of exposed water pipes. They only focus on practicality and lack beauty. The shower screen is a shower that can achieve more functions and is more beautiful. The shower screen generally has an outer shell, and its water pipes are generally covered by the outer shell. At the same time, a switch metering component is generally installed in the outer shell, and the fixing hole on the switch metering component is generally directly fixed with a screw to the mounting hole set on the outer shell. After the installation is completed, the weight of the switch metering component and the inlet and outlet water pipes connected to it are borne by the connection between the screw and the outer shell. In the above installation method, the switch metering component is completely locked in the shell and cannot be fine-tuned. At the same time, the connection between the screw and the outer shell is subjected to greater force and is easy to break. Utility Model Content

[0003] The utility model provides a mounting structure of a shower switch metering assembly, aiming to overcome the above-mentioned shortcomings in the prior art.

[0004] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: a mounting structure of a shower switch metering assembly, comprising an electronic flowmeter and an electronic switch valve, the electronic flowmeter being connected to a water inlet bellows and a water outlet bellows respectively through a lower end joint and an upper end joint, the electronic switch valve being arranged in the middle of the upper end joint, and also comprising an upper limit plate and a lower limit plate arranged at the top and bottom of the front mounting opening in a shower housing, the upper limit plate and the lower limit plate being respectively provided with an upper limit groove and a lower limit groove at the rear ends, the upper pressure plate and the lower pressure plate being respectively connected to the rear ends of the upper limit groove and the lower limit groove for pressing and fixing the water outlet bellows and the lower pressure plate for pressing and fixing the water inlet bellows, an intermediate pressure plate being also arranged in the middle of the mounting opening in the housing, the intermediate pressure plate pressing the electronic flowmeter against the rear cover of the control assembly in the mounting opening from the rear side.

[0005] On the basis of the above technical solution, the present invention can also be improved as follows.

[0006] Furthermore, the upper limit groove and the lower limit groove are both U-shaped grooves opening backwards.

[0007] Furthermore, the left and right ends of the lower pressure plate are fixedly connected to the rear end of the lower limit plate by screws respectively, and the diameter of the joint nut at the connection between the lower end joint and the water inlet bellows is larger than the width of the U-shaped groove in the left and right directions.

[0008] Furthermore, a limiting groove is provided on the back side of the rear cover, and a limiting protrusion matching with the limiting groove is provided on the front part of the electronic flow meter.

[0009] Furthermore, the left and right sides of the intermediate pressure plate are fixedly connected to the left and right connecting columns in the shell by screws.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The switch metering assembly is not directly locked and fixed to the shower housing by screws, but the electronic flow meter and the inlet and outlet water bellows are compressed and limited by the upper limit plate, the lower limit plate and the middle limit plate. The self-weight of the switch metering assembly is mostly supported by the water inlet bellows. At the same time, the inlet and outlet water bellows also have the function of limiting the switch metering assembly in the horizontal direction. Compared with directly locking it with the housing by screws, the specific position of the switch metering assembly can be fine-tuned during the installation process with a certain degree of freedom. At the same time, the pressure of the switch metering assembly on the housing due to its own weight can be properly dispersed, the shower housing is not easily damaged, and the switch metering assembly is more convenient to disassemble and assemble.

[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0020] In the description of the present invention, if terms indicating orientation such as "up", "down", "left", "right", "top", "bottom", "inside" and "outside" are used, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] like Figures 1 to 4 As shown, the utility model provides an installation structure of a shower switch metering assembly, which includes an electronic flowmeter 1 and an electronic switch valve 2. The electronic flowmeter 1 is connected to a water inlet bellows 3 and a water outlet bellows 4 through a lower end joint and an upper end joint respectively, and the electronic switch valve 2 is provided in the middle of the upper end joint. The utility model also includes an upper limit plate 6 and a lower limit plate 7 which are arranged in a shower housing 5 at the top and bottom of the front installation port, and the upper limit plate 6 and the lower limit plate 7 are provided with an upper limit groove and a lower limit groove at the rear ends respectively, and the upper pressure plate 9 for pressing and fixing the water outlet bellows 4 and the lower pressure plate 10 for pressing and fixing the water inlet bellows 3 are respectively connected to the rear ends of the upper limit groove and the lower limit groove, and an intermediate pressure plate 11 is also provided in the middle of the installation port in the housing 5, and the intermediate pressure plate 11 presses the electronic flowmeter 1 to the rear cover of the control assembly in the installation port from the rear side.

[0022] It should be noted that the depth of the upper limit groove and the lower limit groove in the front-to-back direction and the width in the left-to-right direction should be equivalent to the metal bellows (equivalent to the outer diameter of the water inlet bellows and the water outlet bellows), so that when the upper and lower pressure plates are locked by the screws at the left and right ends, the metal bellows is effectively compressed and limited in the upper and lower limit grooves. In order to ensure a better compression and limiting effect and provide a certain vertical limiting capacity, rubber gaskets can be installed in the upper and lower limit grooves or on the sides where the upper and lower pressure plates contact the bellows to increase the vertical friction resistance.

[0023] The shower housing is preferably made of hard plastic, and the upper and lower pressure plates and the middle pressure plate can be made of either hard plastic or stainless steel. The other end of the water inlet bellows is connected to a tap water or hot water pipe, which is generally buried in the wall and connected to the lower end of the water inlet bellows after exiting the wall through a triangular valve. The water inlet bellows has the dual functions of feeding water into the electronic flow meter and providing certain support to the electronic flow meter.

[0024] In one embodiment of the present invention, the upper limit groove and the lower limit groove are both U-shaped grooves opening backwards.

[0025] It is understandable that, in addition to the U-shaped groove, it can also be a semicircular groove. In this case, one side of the upper and lower pressure plates is correspondingly provided with the other half of the semicircular groove. This form of clamping structure should also be included in the protection scope of the utility model.

[0026] In one embodiment of the utility model, the left and right ends of the lower pressure plate 10 are fixedly connected to the rear end of the lower limit plate 7 by screws respectively, and the diameter of the joint nut at the connection between the lower end joint and the water inlet bellows 3 is larger than the width of the U-shaped groove in the left and right directions.

[0027] It should be noted that the screw fixing method can also be replaced by a snap-on method, or the connection can be achieved by a flip-up quick-release fastener.

[0028] In one embodiment of the present utility model, a limiting groove is provided on the back of the rear cover, and a limiting protrusion 12 cooperating with the limiting groove is provided on the front of the electronic flow meter 1 .

[0029] It should be noted that the control component is installed in the installation port, and the rear cover is the back cover of the control component. After a limiting groove is set on it, when the limiting protrusion on the electronic flow meter is engaged, the electronic flow meter is effectively limited in the up, down, left and right directions. The limiting protrusion can also transfer part of the weight of the switch metering component to the control component to disperse the pressure.

[0030] In an embodiment of the present invention, the left and right sides of the intermediate pressure plate 11 are fixedly connected to the left and right connecting columns 13 in the housing 5 by screws.

[0031] It can be understood that the connecting column is a column with a screw hole, which can be integrally formed with the shell.

[0032] In one embodiment of the utility model, it also includes an intermediate limiting fastener 14, which has an arc groove for pressing the upper end joint from the front side, and the left and right ends of the intermediate limiting fastener 14 are fixedly connected to the intermediate pressure plate 11 by screws.

[0033] It should be noted that an elastic rubber pad can be provided in the arc groove of the middle limit fastener, so as to increase the ability of the middle limit fastener to resist vertical relative displacement after being pressed against the upper end joint. The middle limit fastener also effectively limits the switch metering assembly in the left and right and front and back directions.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
