- the invention has the object of developing the known from WO 2006/099578 A1 pressure gauge such that the measuring mechanism is better secured against damage by impact or the like.
- the object is achieved by a screw for coupling the measuring unit with the shock steam device
- the invention is based on the finding that a screw ensures a reliable coupling of the two interconnected parts, in all spatial directions So stop the screw, for example, not only under stress on pressure, but also in case of complaint to train
- the measuring mechanism is reliable against Damage caused by impact or the like, regardless of which direction the impact acts
- the measuring mechanism and / or the shock-absorptive device has / have an opening in which an internal thread of the screw connection is arranged
- the shock vapor device and / or the measuring mechanism has / have a lug on which an external thread of the screw is arranged
- An inner and / or an outer thread of the screw connection is / are inventively preferably einstuckig formed with the measuring unit or the shock steam device
- an internal thread of the screw is formed on a threaded insert
- a threaded insert according to the invention is preferably arranged in those opening of the measuring mechanism or shock absorber, within which the internal thread should lie for the screw connection.
- the pressure gauge has a housing, wherein the threaded insert presses a shoulder on the shock absorbing device in an undercut of the housing.
- the threaded insert is not only used as part of the screw connection, but also for keeping the shock absorbing device on the housing.
- a housing is provided on the pressure measuring device, wherein the Stoßdämpf issued is attached to the housing.
- This attachment can be realized in any way, in particular by positive engagement, by friction or by fasteners.
- an internal thread of the screw is attached to the inner wall of a channel, over which the
- Measuring unit is connected to the outside world.
- the channel is used for two purposes, namely on the one hand to connect the measuring unit with the outside world and on the other to accommodate the internal thread.
- the gas (air) whose pressure is to be measured is fed to the measuring unit through the channel.
- the channel for transmitting a mechanical measured quantity, for example by picking up a shaft which is rotated as a function of the prevailing pressure.
- the channel can also accommodate lines, for example electrical lines for passing measured quantities.
- a device for securing against rotation of the measuring mechanism is provided with respect to the shock absorbing device.
- Such an anti-rotation serves the accuracy of the (read) measurement result
- the anti-twist device preferably has a profiling.
- a profiling is based on the principle of frictional and / or positive locking.
- the profiling can be ribs, corrugations or the like
- the invention provides for solving the problem of better securing the measuring mechanism against damage by impact or the like, that the shock absorber means an enclosure on the side of a bottom of the measuring mechanism or on the side of the screw Has edge of the measuring unit
- the enclosure runs around the measuring unit preferably along the edge
- the enclosure completely encloses the measuring mechanism in circumferential direction.
- the enclosure can also serve to seal the measuring unit in addition to the impact steaming
- an import tray is provided on the enclosure
- a device for securing against rotation of the movement with respect to the enclosure can preferably be provided in order to increase the measurement / reading accuracy
- the anti-rotation may in turn have a profiling, which may be ribs, waves or the like
- a profiling which may be ribs, waves or the like
- it can be designed as one piece with that part of the shock steam device which serves for the screw connection.
- it is preferably fastened to a housing of the pressure measuring gauge
- Such an attachment can in turn be configured as desired, in particular by friction, positive engagement or by fasteners
- a (further) part of the shock-steam device is preferably located on the side of the measuring unit facing away from the floor or the screw connection
- the (further) part of the shock-steam device can in turn be formed by a separate component or a separate module. However, it can also be configured as one-piece with the enclosure and / or the part of the shock-vapor device associated with the screw connection
- a spacer between the measuring mechanism and the on the side facing away from the bottom or the screw side of the measuring mechanism part of the shock absorber device is provided
- Such a spacer creates a space between the individual parts of the shock-steam device for accommodating the measuring system. This space is retained, for example, even when a component or an assembly of the shock-steam device is subjected to pressure.
- Such a compressive stress presttressing
- a means for securing against rotation of the spacer is provided with respect to the measuring unit
- a device for securing against rotation of a reading scale with respect to the spacer is furthermore preferably provided according to the invention
- This rotation also prevents rotation of the reading scale with respect to the measuring unit, so that the measuring and reading accuracy is maintained
- At least part of the shock steam device preferably has a hardness of 40 ° to 80 ° Shore A.
- shock steam device has one or more of the following materials
- Synthetic rubber preferably nitriles butadiene rubber (NBR), terpolymer elastomers (rubber), preferably ethylene-propylene-diene rubber
- FIG. 1 shows a sectional schematic exploded view of parts of a blood pressure measuring device according to a preferred embodiment of the invention
- FIG. 2 is the same view as FIG. 1, but of a different embodiment of the invention;
- Figure 3 shows the same representation as the figures
- the blood pressure measuring apparatus includes a measuring unit 10, an enclosure 12 for an edge 14 of the measuring unit, a steamer 14, a housing 16 and a threaded insert 18.
- the enclosure 12 has an import chute 20 to facilitate the insertion of the measuring unit 10 into To facilitate the enclosure 12
- a shoulder 22 with an external thread 24 is attached to the movement 10
- the threaded insert 18 has a corresponding internal thread 26
- a shoulder 30 with a relief 32 is attached to a floor 28 of the housing 16. In the assembled state, it presses Threaded insert 18, the bead 34 in the undercut 32, so that the steamer 14 is held form gleichig on the housing 16
- the blood pressure device of Figure 2 is essentially the same as that of Figure 1 In particular, it has namely the steamer 14 with the threaded insert 18 and the enclosure 12 in addition, but via a dial 36, a spacer 38 and the measuring mechanism 10 on the
- the steamer 40 is printed by interposing a transparent plastic disc 42 of a locking ring 44 in Figure 2 down by the locking ring 44 is screwed onto the housing 16
- (not shown) is provided on the locking ring 44 an internal thread while the housing 16 has an external thread (not shown)
- the exemplary embodiment according to FIG. 3 corresponds essentially to that according to FIG. 2, but does not show the steamer 14 with the threaded insert 18. Consequently, the lug 22 is also not provided on the measuring mechanism.
- the steamer 40 and the enclosure 12 only the protection against shock and sealing
- Figure 4 shows an exemplary embodiment, in which the enclosure 12 with the steamer 14 is executed einstuckig It is a channel 46 can be seen, which serves to the measuring unit 10 to supply that air whose pressure is to be measured
- the continuation of the channel 46 is formed by a channel 48 which coincides with the interior of the threaded insert 18
- the meter has a further channel with which it is connected to the channel 48 and 46, respectively
- an anti-rotation device 50 in the form of a projection is provided on the dial 36, which engages in a corresponding groove (not shown) of the spacer 38.
- An anti-rotation device arranged on the spacer 38 carries the reference number 51
- Steamer 40 each surface provided with a wave-shaped profile, so that the adjacent thereto components (housing 16, movement 10, spacer 38 and / or threaded insert 18) are secured against rotation
