Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of fork sheet driven type tensimeter, comprise the table body, be provided with the multi-turn bourdon tube in the table body, the dial plate of fixedlying connected with the table body is arranged above the table body, the needle pivot that also can rotate freely perpendicular to card is housed on the dial plate, and described dial plate is provided with and shows the watch glasses that body links to each other, and it is characterized in that: described needle pivot passes dial plate, the upper end of needle pivot is fixedly connected with pointer, fixedlys connected with the fork sheet in the lower end of needle pivot; Have the center pit of the importing gas of axial setting in the middle of the described table body bottom, the head that described multi-turn bourdon tube does not flatten inserts to be fixed in the center pit and with it after bending and is communicated with, and the afterbody of described multi-turn bourdon tube is rolled over straight flange and is connected with the fork sheet after sealing.
The technical solution of the utility model can also be further perfect:
Form integral body by watchcase that links to each other with the table body and the supporting disk that is installed in the watchcase between described table body and the watch glasses; Described dial plate is fixed on the supporting disk.
As preferably, be provided with outside the described needle pivot and the movable axle sleeve that cooperates of axle, described axle sleeve is fixed in the axis hole of dial plate; Pad is equipped with in described fork sheet outer face of fixedlying connected with needle pivot.
As preferably, described fork sheet is fixed by the fork sheet prong of its end and the folding straight flange socket of multi-turn bourdon tube.
As preferably, the entrance point of described center pit is provided with filtrator.
As preferably, described table body bottom surface is provided with connecting portion, on the described connecting portion connecting thread is arranged, and the O-ring seals that radially is provided with is housed above the described connecting thread.
The beneficial effects of the utility model are:
1, adopt multi-turn bourdon tube and fork sheet transmission structure combining, the pointer beat increases, and elastic drive is not subjected to resistance, and the scale display precision improves, and convenient the observation is applicable to the coupling arrangement of various manometers;
2, pointer, fork sheet connect firmly, and unitary construction is simple, and cost of manufacture is low, and it can replace domestic at present, general small-scale structure pressure display table in the world.

Embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment 1:
As shown in Figure 1, fork chip transmission tensimeter is made up of table body 1, dial plate 13, watch glasses 11, pointer 12, needle pivot 10, fork sheet 8, pad 9, multi-turn bourdon tube 6 and filtrator 3.The centre bit of wherein showing the body bottom is equipped with a vertical centre hole 2, and the entrance point in this hole is provided with a gas filter 3, and this filtrator imports in the bourdon tube 6 gas after filtering again, and in the external thread back of table body bottom one O RunddichtringO 4 is housed.
The needle pivot outside is provided with and the movable axle sleeve that cooperates of axle, and axle sleeve is fixed in the axis hole of dial plate.All the other are with embodiment 1
Fork sheet transmission tensimeter as shown in Figure 2, structure be basically with embodiment 1, and it is different that its key distinction is to show the shape of body, and the part that supports dial plate and coupling arrangement is different.
Its table body diameter adopts big or small two table tops to make it to increase dial plate, increases pointer, and scale shows more obvious.
Fork sheet transmission tensimeter as shown in Figure 3, structure be basically with embodiment 1, and it is different that its key distinction is to show the shape of body, and the part that supports dial plate and coupling arrangement is different.
This table body 1 is that a kind of hexagonal metal material is made, with metal shell 16 towards riveting moulding blended rubber water-stop, supporting disk 15 adopts bonding agent to be adhesively fixed with watchcase 16 and dial plate 13,11 of watchcase 16 and watch glasses are placed O-ring seal 17, and make watch glasses 11 and watchcase 16 fixing seals with punching press reducing mode, on the pressure relief vent of the center of watch glasses 11, post an adhesive sticker 14 to seal.
