As depicted in figs. 1 and 2, be convenient to the shooting direct-reading gas meter adjusting levelness, comprise gas meter, flow meter body 6 and bracing frame.
Described gas meter, flow meter body 6 top is provided with level meter 4.
Support frame as described above comprises bottom bracket 1, bracket 2,4 adjusting bolts 3:
Described bottom bracket 1 comprises horizontally disposed bottom plate 11, the bottom plate 12 vertically arranged and Duo Gen support bar 13, described bottom plate 11 is fixedly connected on bottom plate 12 upper end, described support bar 13 one end is fixed on bottom plate 11, and the other end is fixed on bottom plate 12; Aforementioned bottom plate 11 and bottom plate 12 be one-body molded, one-time formed square bracket preferably, in practical application, also can be two independently plates, adopts welding, bonding, the mode such as to inlay is fixed together;
The upper mounted plate 22 that described bracket 2 comprises horizontally disposed mounting plate 21 and vertically arranges, described mounting plate 11 is arranged on bottom plate 11, and fixed plate 22 lower end is fixed on mounting plate 21; Above-mentioned mounting plate 21 and upper mounted plate 22 be one-body molded, one-time formed square bracket preferably, in practical application, also can be two independently plates, adopts welding, bonding, the mode such as to inlay is fixed together;
The back side of fixed plate 22, bottom plate 12, bottom plate 11, mounting plate 21 is all in the same plane; Just bracket 2 and bottom bracket 1 back side entirely can be fitted on metope when such installation and install;
Above-mentioned mounting plate 21, bottom plate 11 are rectangular slab, and 4 adjusting bolts 3 are separately positioned on four angles of mounting plate 21, and adjusting bolt 3 lower end contacts with the upper surface of bottom plate 11; Fixed plate 22 front is also provided with the rectangular enclosure 221 of gas meter, flow meter body 6, during use, gas meter, flow meter body 6 is arranged in this rectangular enclosure 221, lower end contacts with mounting plate 21, is supported by mounting plate 21, when mounting plate 21 have slightly tilt time, gas meter, flow meter body 6 also tilts, now level meter 4 just can show its out-of-level state, and now adjust corresponding adjusting bolt 3, gas meter, flow meter body 6 is adjusted to horizontality by eye-level instrument 4.Therefore, bracket 2, bottom bracket 1 even gas meter, flow meter body 6 need not be operated completely, only rotate adjusting bolt 3 and just gas meter, flow meter body 6 can be adjusted to horizontality, very simple and convenient during adjustment, do not need instrument and the professional skill of specialty yet.
In addition, gas meter, flow meter body 6 in the present embodiment adopts wireless self-networking of the prior art shooting direct-reading gas meter, it is generally provided with imageing sensor 7, wireless self-organizing network nodes equipment etc. on gas meter, flow meter body 6, its imageing sensor 7 is general just to the dial plate of gas meter, flow meter body 6, the gas meter, flow meter body of the meter reading terminal be such as not limited in Chinese patent CN203165194U can be adopted in the present embodiment, just repeat no more the structure of gas meter, flow meter body 6 herein.
Embodiment 2:
On the basis of embodiment 1, the shooting direct-reading gas meter bracing frame of the present embodiment also comprises height adjusting structure 5 further.
As shown in Figure 3 and Figure 4, described height adjustment mechanism 5 comprises gear 51, connecting link 52 and lever 53, fixed plate 22 is also provided with the second cavity 222 installing gear 51 and the through hole 223 installing connecting link 52, the part latch of gear 51 reaches rectangular enclosure 221 from the second cavity 222; Plane in upper mounted plate 22 place of the axis being parallel of described through hole 223 and be parallel to surface level, connecting link 52 can rotate in through hole 223, connecting link 52 one end is fixedly connected on gear 51 center, the other end stretches out upper mounted plate 22 and is fixedly connected with lever 53, under the power transmission of connecting link 52, when rotating lever 53, can rotate by driven gear 51.
As shown in Figure 5, described gas meter, flow meter body 6 back side is provided with multiple draw-in groove 61 matched with the latch of gear 51, and the length direction of described draw-in groove 61 is consistent with horizontal direction.
Aforementioned height governor motion 5 has two effects:
One, because the rectangular enclosure 221 in the present embodiment will fix gas meter, flow meter body 6 preferably, prevent gas meter, flow meter body 6 from tilting, therefore the width of rectangular enclosure 221 should not be too large, preferably identical with the width of gas meter, flow meter body 6, prevents gas meter, flow meter body about 6 to have gap and cause crooked.And rectangular enclosure 221 width suitable with gas meter, flow meter body 6 width time, gas meter, flow meter body 6 installs or removes and all compares effort.And first of this height adjustment mechanism 5 effect is exactly installation and removal gas meter, flow meter body 6, when gas meter, flow meter body 6 is installed, gas meter, flow meter body 6 is snapped in rectangular enclosure 221 from top to bottom, gas meter, flow meter body 6 lower end is connected with mounting plate 11; During demolition diaphragm gas meter body 6, gas meter, flow meter body 6 is released rectangular enclosure 221 from bottom to top; Concrete operations mode rotates lever 53 for operating personnel, and gear 51 rotates, and the latch of gear 51 drives gas meter, flow meter body 6 to rise or decline, thus completes the installation or removal of gas meter, flow meter body 6.
Two, when adjusting bolt 3 cannot regulate, gas meter, flow meter body 6 can raise or lower by height adjustment mechanism 5, carry out height control, then between bottom plate 11 and gas meter, flow meter body 6, be encased inside pad make gas meter, flow meter body 6 maintenance level, adopt the height of this structural adjustment gas meter, flow meter body 6 of height adjustment mechanism 5 convenient and laborsaving, be also not easy to damage gas meter, flow meter body 6.
Embodiment 3:
On the basis of embodiment 1 or embodiment 2, in the present embodiment, bottom bracket 1 is further improved, particularly: the support bar 13 of bottom bracket 1 and the angle between bottom plate 11 and bottom plate 12 are 45 °, many support bars 13 are evenly arranged in the horizontal direction, make support bar 13 be evenly distributed in below bottom plate 11, bottom plate 11 is stably supported.
In addition, in the present embodiment, described level meter 4 adopts air-bubble level, simple, intuitive ground reflection heeling condition, and cost is low.
Below be only the preferred embodiment of the present invention, protection scope of the present invention be not only confined to above-described embodiment, all technical schemes belonged under thinking of the present invention all belong to protection scope of the present invention.It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, should be considered as protection scope of the present invention.
