Abstract
The utility model discloses a wet type direct-reading water meter head excellent in air tightness. The wet type direct-reading water meter head excellent in air tightness comprises a character wheel box and a compression ring, wherein the compression ring is welded on the upper end face of the character wheel box, a photoelectric module is arranged inside a cavity in the lower portion of the character wheel box, a ling passing groove allowing a communication line to pass through to be connected with the photoelectric module is formed in the upper portion of a box body of the character wheel box, a plurality of circles of annular grooves are formed in the upper end face of the character wheel box, protruding rings matched with the annular grooves are arranged on the lower end face of the compression ring, and the protruding rings are embedded in the annular grooves and then are welded. According to the wet type direct-reading water meter head excellent in air tightness, the welding surface between the character wheel box and the compression ring is of a concave-convex matching labyrinth groove structure, better air tightness is achieved after the character wheel box and the compression ring are welded in an ultrasonic mode instead of in a plane mode, and most importantly, no plastic welding materials can flow out from the circumferential edge after the character wheel box and the compression ring are welded in the ultrasonic mode; due to the fact that the line passing groove, of the communication line, in the character wheel box is designed to be of an inclined surface structure, production personnel can enable the communication line to penetrate through the line pass groove conveniently to further be connected with the photoelectric module in the character wheel box. Compared with the prior art, the wet type direct-reading water meter head has the advantages of being good in air tightness and high in production efficiency.
Description
Technical field
The utility model relates to a kind of wet type direct-reading water meter, particularly a kind of gauge head structure of wet type direct-reading water meter.
Background technology
The gauge outfit of wet type photoelectric direct reading remote transmission water meter has reflective and two kinds of structural shapes of transmission-type from principle of work.Which kind of structural shape no matter, being connected and fixed between its character wheel box and glass and the pressure ring all is to adopt ultrasonic soldering.The face of weld of character wheel box and pressure ring all is designed to planar structure at present, so that two face of weld are easily bad because welding the gauge outfit impermeability that causes not in place after ultrasonic soldering, welding in addition has plastic melting to connect material after excessive to flow out between circumference, do rear processing deburring and process.On the other hand, the threading hole slot structure of character wheel box connection is right angle transition through wires hole, and this structure is the relatively good demoulding of loosing core from the mould manufacturing, but for the production operation personnel, connection passes the efficient that wastes time and energy from this hole low, and production cost is corresponding higher.
The utility model content
The wet type direct-reading water meter gauge outfit that provides a kind of impermeability good is provided the purpose of this utility model.
The wet type direct-reading water meter gauge outfit that this impermeability provided by the utility model is good, comprise character wheel box and pressure ring, pressure ring is welded in the upper surface of character wheel box, in the lower cavity of character wheel box optical-electric module is arranged, the top of character wheel box box body is useful on the threading hole slot that the connection that is connected with optical-electric module passes.There are some ring annular grooves the upper surface of described character wheel box, and there is the bulge loop with described annular groove coupling the lower surface of described pressure ring, and bulge loop is embedded in the annular groove and welds.
Described threading hole slot is the inclined hole groove that runs through described character wheel box upper box body sidewall, and its endpiece has independently ply-yarn drill groove, and ply-yarn drill line of rabbet joint draw-in groove place is connected with the communication ply-yarn drill.
Character wheel box of the present utility model adopts the concavo-convex labyrinth bathtub construction that cooperates with face of weld between the pressure ring, can guarantee after the ultrasonic soldering between the two better compared to the plane-welding impermeability, the most important thing is not have after the ultrasonic soldering plastic melting and connect material and flow out from circumferential edges.The threading hole slot of connection is designed to ramp structure on the character wheel box, make things convenient for producers with connection from then on the hole penetrate with character wheel box in being connected of optical-electric module.Compare with prior art, have the advantage that impermeability is good, production efficiency is high.

Embodiment
To shown in Figure 5, the wet type direct-reading water meter gauge outfit that this impermeability that the utility model provides is good comprises character wheel box 1, pressure ring 2, optical-electric module 3, inserts 4, character wheel 5, connection 6, plug 7, communication ply-yarn drill 8 such as Fig. 1.Pressure ring 2 is welded in the upper surface of character wheel box 1, in the upper chamber 14 of character wheel box 1 optical-electric module 3 is arranged; Have in the lower cavity 15 by character wheel 5 and the inserts 4(our unit patent applied for supporting with it: the gauge outfit that is used for transmission-type wet type photoelectric direct reading water meter, the patent No.: the threading hole slot 11 that the print wheel component that ZL201220666060.3) forms, the top of character wheel box 1 box body have the connection 6 of being convenient to be connected with optical-electric module 3 to pass.There are some ring annular grooves 12 upper surface of character wheel box 1, and there is the bulge loop 21 with annular groove 12 couplings the lower surface of pressure ring 2, and bulge loop 21 is embedded in welding in the annular groove 12.Threading hole slot 11 is for running through the inclined hole groove of character wheel box 1 upper box body sidewall, and its endpiece has independently ply-yarn drill groove 13, and ply-yarn drill groove 13 places are connected with communication ply-yarn drill 8.
During connecting communication line 6, to penetrate the threading hole slot 11 of connection 6 from character wheel box 1 first, then with flatiron connection 6 is welded on the circuit board of optical-electric module 3, and slowly packs into optical-electric module 3 in the module cavity 14 of character wheel box 1 and flatten, notice that connection 6 must be stretching.Connection 6 connects and rear optical-electric module 3 is sealed encapsulating, carries out fluid-tight after glue is done, and plug 7 is contained on the fluid-tight mouth of character wheel box 1.
At last communication ply-yarn drill 8 is fixed on ply-yarn drill groove 13 positions of threading hole slot 11 endpiece of character wheel box 1, communication ply-yarn drill 8 can effectively protect connection 6 not to be subjected to the impact of watch glasses screw thread when twisting watch glasses.
