Closing member 20 designs are collaborative with bottom 10.It has the end face shown in a bottom surface 21 and Fig. 2.

Two

projections

26 and 27 are supported in bottom surface 21, and projection has shoulder, and are arranged so that they can be inserted in the through

hole

14 and 15 of bottom 10 simultaneously, at this moment, 20, two projections 26 of rotary closing spare and 27 depend on that the direction of rotation is cw or conter clockwise, along

groove

16a, 16b; 17a, 17b slides.

Closing member 20 has two through

holes

24 and 25, and their position makes, is positioned at groove 16a at

projection

26 and 27, and among the 17b or 16b, in the time of among the 17a, they are 10 the through

hole

14 and 15 towards the bottom respectively.

The decomposition diagram of lid 1 when Fig. 2 illustrates from observation.

The end face 22 of closing member 20 supports a bolt 23, and it has a passage 28 and a groove 29, groove 29 and passage 28 right angle intersections.Passage 28 has the potted line that will describe in detail below accepting.

As shown in Figure 1, ring closeding piece 30 has two

dops

34 and 35, and they pass through the through

hole

24 and 25 in the closing member, and penetrates in the

hole

14 and 15 of bottom 10.Yet

dop

34 and 35 width are greater than

groove

16a, 16b; 17a, the width of 17b.Make

dop

34 and 35 can not be inserted into

groove

16a, 16b like this; 17a is among the 17b.

Closure member 30 has a groove 33, and it is suitable for accepting the bolt 23 on the closing member.The projection 39 that has otch 38 is arranged in groove 33, makes when

part

20 and 30 fits together, and projection 39 penetrates in the groove 29 of bolt 23.At this moment, otch 38 is in and passage 28 positions aligning.

As shown in Figure 2, the end face 32 of closure member 30 has a guide groove 37 that contains otch 38.Guide groove 37 makes that inserting potted line when each

part

10,20 and 30 is assembled together is easier to.In the both sides of groove 37, form two

lateral groove

40a, 40b makes to be easier to catch closure member 30.

Fig. 3 illustrates the lid that assembles when observing down.Bottom 10 has opening 11 and 12, is used for wanting the osed top device fixing on every side it.Because fixing like this, bottom 10 is not removable usually.

In order to close opening 13, and seal cover cap, at first closing member 20 is fixed to bottom 10 with anchor fitting, in an illustrated embodiment, these anchor fittings are by through

hole

14 and 15 and their

groove

16a, 17b or 16b, 17a and the

projection

26 and 27 that has shoulder, and latching device constitutes, in this example, latching device be by

dop

34 and 35 and through

hole

24 and 25 constitute.

For closing member 20 being fixed on the bottom 10, at

first projection

26 and 27 is inserted in corresponding through hole 14 and 15.Then, make

projection

26 and 27 move to

corresponding groove

16a, 17b by rotation.Because well width is littler than the shoulder on the projection, this prevents that closing member 20 from vertically being extracted out.In this position, the through hole 24 that closing member has and 25 is 10 corresponding through

hole

14 and 15 towards the bottom.

In order to keep closing member 20 to be in this position still, need to use latching device.The through

hole

24 and 25 that passes in the closing member 20

inserts dop

34 and 35, passes through the through

hole

14 and 15 of bottom 10 then.Because the width of

dop

34 and 35 is greater than

groove

16a, 16b, 17a, the width of 17b,

dop

34 and 35 can not move in the groove, prevents the closure member rotation, thereby closing member 20 is locked on its position.

Then as following with reference to as described in Fig. 4, make potted line that closure member 30 is fixed to closing member 20.

Fig. 4 comprises Fig. 4 A and 4B, and they are orthogonal section-drawings of stack-mounted lid.Fig. 4 A is the section-drawing along the lid of the axis of the groove in the closing member 20 29.Fig. 4 B is the section-drawing along the lid of the axis of the guide groove 37 of closing member 20.In an illustrated embodiment, when each part was assembled together, these two axis were vertical mutually, were appreciated that they also can be arranged to other relative position.

When closing member 20 and closure member 30 are assembled together, bolt 23 engaging grooves 33, projection 39 penetrates into groove 29.In this structure, the bolt 23 on the closing member is collaborative with the otch that is provided with projection 39 38, forms the passage of potted line 50.Potted line is inserted into guide groove 29, and guide groove 29 is with potted line guide channel 28, and in passage 28, it passes otch 38, brings out by other one of passage 28.Like this, closure member 30 is fixed to closing member.The bottom of the protruding 39a that sealed line 50 stops stops closure member 30 vertically to be extracted out, and potted line 50 roof 23a by passage 28 own keep static.

In case its end connects together via the lead sealing (not shown), potted line 50 can not be extracted out from passage 28, so the integraty of closing of opening 13 is kept.

In case device puts in place, and by sealing member sealing, the unique way by opening 13 is to make potted line or sealing break.Not departing from scope of the present invention may be by all embodiment for above-mentioned device.

For example, can be provided with and the supporting single through hole of a groove of bottom, correspondingly, be provided with a projection of shoulder, support by closing member, and be suitable for being inserted in the hole, slide to groove, simultaneously the single dop that supports by the closure member assembly that forms of tightening cover vertically.

Also plural through hole can be set in the bottom, collaborative with same number of projection and dop.

In another scheme, each through hole that the bottom is provided with is not supporting with groove, and for example the hole is a rectangle.At this moment, each projection that has a shoulder must be rectangle and be suitable for axis rotation 1/4th commentaries on classics around it.Each projection is inserted in its corresponding hole, then, makes its rotation, thus the locking shoulder, promptly with respect to the length of the projection at the edge in hole.In case closure member puts in place, no longer can contact them in order to unclamp projection.Therefore closing member is fixed to the bottom.

It is useful that the table meter waits measuring instrument to be provided with above-mentioned lid, for example, is used to guarantee to enter the integraty of closing that table is counted the window of read/write device.This read/write device can either also can be programmed to it by the meter reading meter, particularly when using suitable expenses standard programming, therefore, seals the passage that enters the inside in mode simply and cheaply, so that make willful deceit behavior exposure, is useful especially.
