Description
Technical Field
The utility model belongs to the technical field of the water gauge is made and specifically relates to indicate a circuit board mounting structure for water gauge.
Background
With the continuous development of industrial economy and urban scale, water meters are being installed and used more and more widely in industry and in residential life as meters for measuring the flow of water used. At present, in the water gauge industry of making, the fixed mode of circuit board mainly has the fix with screw, the buckle is fixed or ordinary close-fitting is fixed, and there is the easy distortion of circuit board defect even damage of fix with the buckle of screw, and ordinary close-fitting is connected the mounting hole on the circuit board and erection column through the mode of close-fitting, its tolerance requirement is relatively tighter, the situation too loose or too tight of connection appears easily, too loose leads to the circuit board to fix insecure, too tight easily leads to the circuit board not to install or circuit board fracture appears, consequently, it needs a circuit board mounting structure for the water gauge in order to solve above-mentioned problem to wait for urgent need.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
An object of the utility model is to provide a circuit board mounting structure for water gauge has not only avoided the problem of easy damage circuit board, has reduced the installation tolerance requirement simultaneously, has realized the stable installation of circuit board, has improved the stability of circuit board connection. In order to achieve the above purpose, the utility model adopts the following technical scheme:
(II) technical scheme
The utility model provides a circuit board mounting structure for water gauge, includes circuit board box and circuit board, circuit board box bottom is equipped with the erection column, be equipped with the mounting hole on the circuit board, still include the hollow post of rubber, the hollow post cover of rubber is established on the erection column, the mounting hole close-fitting cover is established on the hollow post of rubber.
Furthermore, the top of the rubber hollow column is rounded, and the bottom of the rubber hollow column is provided with an annular check ring.
(III) advantageous effects
Compared with the prior art, the utility model obvious advantage and beneficial effect have, particularly, the utility model discloses an add the hollow post of rubber between mounting hole and erection column, not only avoided the problem of the easy damage circuit board, reduced the installation tolerance requirement simultaneously, realized the stable installation of circuit board, improved the stability that the circuit board is connected.

FIG. 1 is a schematic view of the present invention prior to installation;
fig. 2 is a sectional view of the present invention after installation.
The reference numbers illustrate:
1. circuit board box 11, erection column 2, circuit board
21. Mounting hole 3, hollow rubber column 31 and annular retainer ring
Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
The present invention will be further described with reference to the accompanying drawings and the detailed description.
Referring to fig. 1 and 2, a circuit board mounting structure for a water meter includes a circuit board box 1 and a circuit board 2, a mounting post 11 is disposed at the bottom of the circuit board box 1, a mounting hole 21 is disposed on the circuit board 2, the circuit board further includes a rubber hollow post 3, the rubber hollow post 3 is sleeved on the mounting post 11, the mounting hole 21 is tightly sleeved on the rubber hollow post 3, a gap between the mounting hole 21 and the mounting post 11 is filled up through the rubber hollow post 3, and the gap between the mounting hole 21 and the mounting post 11 can be large or small, so that the tolerance requirement between the mounting hole 21 and the mounting post 11 is greatly reduced.
For the installation of circuit board 2, the rounding is done at 3 tops of the hollow post of rubber, is convenient for make circuit board 2 install in place, and the hollow post of rubber 3 bottoms are equipped with annular retaining ring 31.
The utility model discloses during the installation, install the hollow post 3 of rubber on erection column 11 earlier, the back of targetting in place is installed to the installation, on the hollow post 3 of rubber is installed to 2 tight suits of circuit board after that, treat 2 lower extremes of circuit board and just stand the installation when following annular retaining ring 31 upper end and target in place, because the tight fit installation, circuit board 2 installs the back of targetting in place, the hollow post 3 of rubber will form a arch in mounting hole 21 top, and then prevents the 2 perks of circuit board.
The utility model discloses an add the hollow post of rubber between mounting hole and erection column, not only avoided the problem of the easy damage circuit board, reduced the installation tolerance requirement simultaneously, realized the stable installation of circuit board, improved the stability of circuit board connection.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
