Abstract
The utility model relates to a shockproof pressure gauge which has application to violent shock places, because a sealed communicating device which is full of oil liquid is connected to the driving mechanism of the shockproof pressure gauge. The communicating device is formed by that an arc elastic tube is communicated with a spiral duct through a pressure gauge joint, and the spiral duct is communicated with a corrugated pipe through a throttle valve. Therefore, the utility model can effectively improve the performance of sensitivity and shockproof under the action of the shock absorption of the corrugated pipe and the damping of the spiral duct, having good shockproof performance, and the service life of the shockproof pressure gauge is extended.
Description
The utility model relates to a kind of instrument of gaging pressure, particularly shock-proof pressure gauge.It is applicable to the pressure survey in sharp pounding place.
At present, China produces a kind of shock-proof pressure gauge, and it mainly is to be made of power transmission drum, rubberite, force transmission shaft, left and right elastic arm, gear train and pointer and scale.After pressure is by the damping of power transmission drum, be delivered to rubberite, through passing to force transmission shaft after the damping once more, force left and right elastic arm distortion by upper and lower the moving of force transmission shaft, drive the gear train motion, make pointer rotate the indicated pressure value.But this manometric power transmission drum and elastic arm are the rigidity element, and not only complex process, manufacture difficulty are big for they, and its be out of shape when transmitting pressure little, thereby make the sensitivity of pointer lower.Simultaneously, because the damping effect of power transmission drum and rubberite is not good enough, when pressure was delivered to force transmission shaft, the influence because of vibrations made the upper and lower displacement amount of force transmission shaft big, causes throw of the pointer big, thereby has reduced manometric serviceable life.
The purpose of this utility model is to be to provide a kind of shock-proof pressure gauge, and it can improve sensitivity and shock resistance effectively, increases the service life.
Its concrete solution is: this tensimeter is to design according to Pascal law.On gear train, connect a Communicating device, its two ends airtight formation seal joining device.But Communicating device is to be communicated with spiral duct by pressure tapping by the camber elastic tube, and spiral duct is through the throttle valve seat formation that is connected with corrugated tube.
Embodiment of the present utility model is described in detail in conjunction with the accompanying drawings.
Fig. 1 is the front view of shock-proof pressure gauge
Fig. 2 is the side view of shock-proof pressure gauge
Fig. 3 is an A portion enlarged drawing
In Fig. 1, Fig. 2, place down hollow corrugated tube (3) lower end of shock reducing structure (1) inner chamber airtight, its upper end is an one with throttle valve seat (5) soldering, and is connected.At this moment, corrugated tube (3) inner chamber becomes the shock insulation chamber.Pack into an end of corrugated tube (3) inner chamber of throttle valve seat (5) is equipped with screw (4), and its other end is equipped with hollow leakproof stifled (7).And the lower end of spiral duct (6) and hollow leakproof stifled (7) to be communicated with soldering be one, and compress by gland nut (8), the upper end of spiral duct (6) is communicated with the center pit of pressure tapping (10), and soldering is an one.But the upper end of pressure tapping (10) is connected with watchcase (20) with sunk screw (21), its lower end be set in outside the spiral duct (6), and the last shock reducing structure (9) that is threaded with following shock reducing structure (1) is threaded.Be the camber elastic tube (11) greater than half garden arc, its lower end is connected with pressure tapping (10) by coupling nut (12), and they the two center pit is connected simultaneously, and the upper end follows closely (14) by end socket and end socket nut (13) seals.Thereby form airtight Communicating device.Silicone oil (2) will be filled with the priming by vacuum method in the Communicating device.Gear train by connecting rod (15), elevating arc (16), central gear (17) are formed is connected with index dial (19) with pointer (18) by central gear (17), is connected with elastic tube (11) through end socket nail (14).
When the outside is acted on corrugated tube (3) by measuring pressure by the center pit that descends shock reducing structure (1), the silicone oil of corrugated tube (3) inner chamber is followed Pascal law, to be delivered to elastic tube (11) by fluid by the pressure that measuring pressure produces, make its end distortion, force connecting rod (15) motion that is connected with elastic tube (11), and central gear (17) rotation that drives elevating arc (16) and be meshed with elevating arc (16), thereby pointer (18) is rotated, go up the indicated pressure value at index dial (19).
The utility model is owing to having adopted the seal joining device that is connected and is constituted by corrugated tube, spiral duct and elastic tube, it can improve its sensitivity and shock resistance widely so under the damping action of the damping of corrugated tube and spiral duct, have earthquake-proof function preferably, and long service life.
Claims (2)
1, a kind of shock-proof pressure gauge is characterized in that connecting a Communicating device on gear train, and the two ends of this Communicating device are airtight.And injecting oil liquid.
2, shock-proof pressure gauge as claimed in claim 1, it is characterized in that Communicating device is to be communicated with spiral duct (6) by the pressure tapping (10) that is communicated with it by the camber elastic tube (11) that an end is sealed shape, anti-spiral duct (6) is through being connected with corrugated tube (3) with the leakproof stifled (7) of its connection and throttle valve seat (5) and constituting.
