Description

Technical Field

[0001] The utility model relates to the technical field of water meters, in particular to a buckle type ultrasonic water meter assembly plate. Background Art

[0002] Ultrasonic water meter is a new type of water meter that detects the time difference caused by the change in speed when the ultrasonic sound beam propagates in the water downstream and upstream, analyzes and processes the water flow rate, and further calculates the water flow rate. This ultrasonic water meter has the characteristics of low starting flow rate, wide range ratio, high measurement accuracy and stable operation. In traditional ultrasonic water meters, the ultrasonic sensor in the flow tube is far away from the circuit board. In order to complete the analysis, processing and calculation work, the lead of the ultrasonic sensor is usually a soft wire, and the lead is connected to the circuit board through a pin.

[0003] At the same time, in order to ensure the connection stability between the lead and the circuit board, the flow tube needs to be fixed to the circuit board with screws to prevent the pin from falling off.

[0004] However, it is difficult to assemble the lead wires and the circuit board by pins and the flow tube and the circuit board by screws through a fully automatic assembly line, so the assembly of the lead wires and the circuit board and the flow tube and the circuit board is usually completed manually.

[0005] Because of this, the labor cost of assembling traditional ultrasonic water meters is high, the assembly efficiency is low, and the assembly accuracy is poor. Utility Model Content

[0006] The utility model aims to provide a snap-on ultrasonic water meter assembly plate, which can realize screw-free assembly of flow tubes and circuit boards, facilitate full-automatic assembly lines, improve assembly accuracy and efficiency, and reduce labor costs.

[0007] A buckle-type ultrasonic water meter assembly plate includes a mounting plate, wherein the mounting plate is provided with a sensor limit frame assembly, a circuit board buckle assembly, a circuit board positioning column assembly and a battery compartment;

[0008] The sensor limit frame, circuit board positioning column, circuit board buckle, battery compartment and mounting plate are integrally formed.

[0009] Among them, the sensor limit frame assembly is installed in cooperation with the ultrasonic sensor in the flow tube, the circuit board positioning column assembly is used to support and position the circuit board, the auxiliary circuit board buckle assembly positions the circuit board, and the circuit board buckle clamps and fixes the circuit board. The above structure realizes screwless assembly of the flow tube and the circuit board, which is convenient for fully automatic assembly line assembly.

[0010] Furthermore, the battery compartment is located in the middle of the mounting plate, and the sensor limit frame assembly, circuit board buckle assembly, and circuit board positioning column assembly are distributed around the mounting plate;

[0011] Among them, the sensor limit frame and the circuit board positioning column are located on both sides of the long side of the battery compartment, and the circuit board buckles are distributed on both sides of the short side of the battery compartment.

[0012] Furthermore, a pair of sensor assembly openings are opened on the mounting plate, and the sensor limit brackets are arranged on the sensor assembly openings;

[0013] The sensor limit frame includes a support frame, and the support frame is connected to a sensor line protection column;

[0014] A limit buckle is arranged at the lower end of the support frame, and a sensor hard wire through hole is opened on the sensor wire protection column.

[0015] A plurality of limit clips are used for circumferentially clamping the sensor, so that the clip-on ultrasonic water meter assembly plate is firmly installed above the flow tube. At the same time, the hard wire of the ultrasonic sensor installed in the sensor mounting hole passes through the sensor hard wire through hole. The sensor hard wire through hole protects the hard wire and limits it, so that the hard wire of the ultrasonic sensor is stably welded to the circuit board.

[0016] The thickness of the sensor wire protection column is greater than the thickness of the mounting plate.

[0017] Furthermore, the sensor assembly opening is turned upward to form the support frame;

[0018] The support frame fixes the sensor wire protection column in the middle of the sensor assembly opening via an "X"-shaped connecting plate.

[0019] Furthermore, the circuit board buckle is a straight arm buckle, and a circuit board support column is arranged on the side of the straight arm buckle, and the circuit board support column is lower than the straight arm buckle.

[0020] The straight arm buckle in the above structure clamps the circuit board, and the circuit board also rests on the circuit board support column. The circuit board support column supports the circuit board and can prevent the circuit board from falling off due to loosening of the straight arm buckle, thereby ensuring stable welding of the hard wire of the ultrasonic sensor and the circuit board.

[0021] Furthermore, the circuit board positioning column is a stepped positioning column, and the lower step thereof is a circuit board supporting platform.

[0022] The circuit board positioning column passes through the circuit board to assist the circuit board buckle in positioning the circuit board, thereby improving assembly efficiency. At the same time, the circuit board rests on the circuit board support platform, which supports the circuit board to ensure that the hard wire of the ultrasonic sensor is stably welded to the circuit board.

[0023] Furthermore, the upper end surfaces of all the circuit board support columns and the upper end surface of the circuit board support platform are located on the same plane.

[0024] The above structure enables the circuit board to be stably mounted above the clip-on ultrasonic water meter assembly plate, and can effectively prevent the circuit board from shaking, thereby ensuring that the hard wire of the ultrasonic sensor is stably welded to the circuit board.

[0025] Furthermore, the middle portion of the mounting plate is recessed downward to form a rectangular groove, and the rectangular groove is the battery compartment.

[0026] Furthermore, edge reinforcement ribs are provided at the edge of the lower end surface of the mounting plate, and the edge reinforcement ribs are connected to the two sides of the long side of the battery compartment through transverse reinforcement ribs, and the transverse reinforcement ribs are connected to the edge reinforcement ribs through vertical reinforcement ribs.

[0027] The edge reinforcement ribs, transverse reinforcement ribs, and vertical reinforcement ribs in the above structure can increase the strength and rigidity of the mounting plate, stably support the circuit board, and ensure that the hard wire of the ultrasonic sensor is stably welded to the circuit board.

[0028] Furthermore, the mounting plate, the sensor limit frame, the circuit board buckle, the circuit board positioning column, and the battery compartment are all made of hard plastic.

[0029] The above scheme can ensure that the flow tube and the circuit board are stably connected for a long time, and can also realize the fully automatic assembly line assembly of the ultrasonic water meter, reduce labor costs, and improve assembly efficiency and assembly accuracy.

[0030] Beneficial effects: The utility model realizes screw-free assembly of flow tubes and circuit boards, which is convenient for full-automatic assembly line, thereby reducing labor costs. At the same time, full-automatic assembly line can also improve assembly efficiency and assembly accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
