It should be understood that the following description is only exemplary of the present invention and does not constitute any particular limitation of the present invention. Wherein, fig. 1 and fig. 2 respectively show the structure schematic diagram of the pressure measuring device of the present invention at two different positions.
As shown in fig. 1 and 2, an embodiment of the present invention provides a pressure measuring device 100. The pressure measurement device 100 generally includes a device body 102 and a diverter spool 104.
Specifically, the device body 102 is provided with a pressure gauge interface 106 and a plurality of pressure measurement point interfaces 108. The interior of the device body 102 is provided with a first channel 110 in communication with each pressure point port 108, respectively, and a second channel 112 in communication with the pressure gauge port 106. In other words, each pressure tap port 108 communicates with a first channel 110, while the pressure tap port 106 may communicate with one or more second channels 112.

In other words, in the pressure measuring device 100 of the present invention, the direction change valve body 104 is provided in the device main body 102. When the reversing valve core 104 is reversed to different positions, pressure signals of different positions can be collected and transmitted to the pressure gauge interface 106 through the connecting channel 114 in the reversing valve core 104, and pressure information is displayed through the pressure gauge 206 connected to the pressure gauge interface 106. The device can display the pressure of different pressure measuring points by directly operating the reversing valve core without dismounting the pressure gauge and the pressure measuring joint.
Therefore, in the using process, pressure measurement can be carried out on each point to be measured only by connecting a pressure gauge 206 into the pressure gauge interface 106 and connecting the points to be measured scattered at each position of the working machine into the pressure measuring point interface 108 and adjusting the position of the reversing valve core 104. Therefore, the utility model discloses a pressure measurement device 100 can enough solve the problem of arranging pressure measurement point is concentrated, also can solve the problem that the pressure measurement switches between different pressure measurement points.

Specifically, when the pressure measurement device 100 has performed a pressure measurement operation, the diverter valve spool 104 may be moved such that the second passage 112 communicates with the pressure relief passage 118 via the connecting passage 114, thereby relieving pressure via the pressure relief interface 116.
As shown in fig. 1, the position of the diverter spool 104 relative to the device body 102 is shown in a pressure relief condition. At this time, the pressure measuring device 100 has completed the pressure measurement, and the pressure gauge 206 performs pressure relief via the pressure relief port 116 successively via the pipe, the pressure gauge port 106, the second passage 112, the connection passage 114, and the pressure relief passage 118. In the process, the other first passages 110 are blocked by the direction change spool 104.
As shown in fig. 2, a schematic diagram of the diverter spool 104 is shown in a pressure sensing state at one of the pressure sensing points. At this time, in fig. 2, the 2 nd pressure measurement point port 108 from the left side sequentially passes through the first channel 110, the connection channel 114, the second channel 112, and the pressure gauge port 106, and is connected to the pressure gauge 206 by a pipeline to measure pressure. During this process, the other first passages 110 and the pressure relief passage 118 are blocked by the diverter spool 104.
Similarly, the operation of the other pressure measurement point interfaces 108 is the same as above, and therefore, will not be described in detail here.

Wherein a plurality of pressure tap ports 108 and pressure relief ports 116 may be disposed on a first side laterally spaced from one another and a pressure gauge port 106 may be disposed on a second side, thereby forming a unitary structure as shown in fig. 1 and 2.
During the process described above, in one embodiment, movement of the diverter spool 104 relative to the device body 102 may be accomplished directly via manual manipulation by an operator, i.e., the operator accomplishes the diverting operation directly by hand pulling or pushing the diverter spool 104. In the embodiment shown in fig. 1 and 2, a drive mechanism may also be provided to effect the operation described above.
Specifically, in an embodiment of the present invention, the drive mechanism may be disposed outside the device body 102. And a drive mechanism may be coupled to the diverter spool 104 to drive the diverter spool 104 to move relative to the device body 102.

In operation, the operator can grip the grip portion of the handle 122 and press or lift it. At this time, the manipulation handle 122 is rotated with respect to the mounting base 120. The rotation of the operating handle 122 will drive the direction valve core 104 connected to it to move, so that the direction valve core 104 is switched in different connection states. For example, the state shown in fig. 1 and the state shown in fig. 2.
In an embodiment of the present invention, the end of the diverter valve spool 104 exposed to the device body 102 may be provided with a guide 124.

In other words, the marker point 128 serves to indicate the access of each pressure measurement point interface 108. That is, the operator can know the connection between the connecting channel 114 and each first channel 110 inside the direction switch spool 104 by simply observing the alignment of each mark point 128 and the indicator mark 130. Therefore, the interface alignment device can be convenient for operators to carry out simple operation and interface alignment conveniently.
For example, in the embodiment shown in fig. 1, the indicator mark 130 is aligned with the mark point 128 of the pressure relief interface 116, and then the entire pressure relief channel is now open, and a pressure relief operation may be performed; for another example, in the embodiment shown in fig. 2, the indication mark 130 is aligned with one of the mark points 128, which indicates that the entire pressure measuring channel of the corresponding pressure measuring point interface 108 is connected, and the pressure measuring operation may be performed.
With continued reference to fig. 1 and 2, in an embodiment of the present invention, the diverter spool 104 may be disposed through the device body 102, and the diverter spool 104 may have first and second ends that are opposite each other and exposed to the device body 102. Specifically, a first end of the diverter spool 104 may be rotatably coupled to the other end of the joystick 122 as described above; the second end of the diverter spool 104 may have formed thereon a position marker as described above.
