Specific embodiment
The technical solution of the utility model, but the protection scope of the utility model are described in further detail with reference to the accompanying drawing
It is not limited to as described below.
As shown in Figure 1, a kind of automatic meter pressing mechanism of apparatus for calibrating water meter, including 1, two butt tube 3 of a shell.
In order to make this programme more specificization, the present embodiment is described further the specific structure of shell 1, in shell 1
Logical to form calibrating channel, i.e. shell 1 is the equal of straight-run of pipe, plays the role of conveying calibrating liquid, and improvement is
Straight tube tube wall in this programme is simultaneously non-solid, but hollow cavity is formed after thickening to tube wall, and structural reference is as shown in Figure 5.
And partition 13 is set in the middle part of hollow cavity, and so that hollow cavity is divided into left chamber and right chamber by partition 13, the wherein knot of left chamber and right chamber
Structure is mutually symmetrical.
In order to enable more convenient when to jointed water meter tube head, two butt tubes 3 respectively by 1 end face of shell insertion left chamber and
Right chamber, and ring film 31 is set in insertion end, the other end stretches out 1 end face of shell and forms one section of C-shaped holding groove 2, knot
Structure only needs for water meter tube head to be placed in C-shaped holding groove 2 when refering to what is shown in Fig. 5, docking, and stablizes in order to enable placing, C-shaped
The length of holding groove is 3-5cm.
As shown in figure 3, specifically, butt tube 3 is mounted in left chamber and right chamber, i.e., left chamber and right chamber be respectively inserted into one it is right
Adapter tube 3, so that 3 one end of butt tube, in hollow cavity, the other end, which stretches out 1 end face of shell and meets C-shaped holding groove 2, to be exposed
Outside.Butt tube 3 falls off out of hollow cavity in order to prevent, and hollow cavity both ends are arranged respectively to block 14, that is to say, that by shell 1
Inner and outer wall is arranged to two opposite inverted " L " structures, so that the gap of inner and outer wall end face is equal to 3 thickness of butt tube simultaneously
Form interference fit.Butt tube 3 is located at the setting of one end in hollow cavity ring film 31, ring film 31 by the left chamber at place or
Right chamber is divided into two, and respectively as into pressing chamber 11 and moving back pressure chamber 12, opens on the outside of the shell 1 for pressing 12 corresponding segment of chamber into pressing chamber 11 and moving back
