Description

Gauge with improved assembly {GAUGE}

The present invention relates to a gauge with improved assembly, and more particularly, when a gauge, particularly a pressure gauge, is installed on a connection tab of a container or a pipe, it can be installed while adjusting the direction so that the indicator can be easily checked, and a transmission member for measurement is provided. It relates to a gauge that can be fitted directly into a housing and fixed to improve assembly.

The gauge refers to various measuring instruments. For example, a pressure gauge for measuring the pressure of a fluid is a diaphragm, a Bourdon tube, or an elastic tube such as a spiral tube or a helix tube of the fluid. It is common to measure pressure by reading what is deformed by pressure.

Various gauges, including these pressure gauges, include a housing in which a measuring part such as an elastic tube is built in, and a measuring transmission member connected to one end of the measuring part to transmit a measurement object such as fluid pressure.

In addition, the gauge also includes a display unit for numerically displaying the deformation of the measuring unit such as the elastic tube, such a display unit is provided at the front end of the housing.

In addition, the transmission member for measurement is fixed to the outside of the housing to have a certain rigidity, and has a screw portion and a through hole so as to be screwed to the tab of a conduit or container to maintain the seal.

Taking a conventional pressure gauge as an example, as shown in FIG. 6A (the reference numerals of FIGS. 6A and 6B describing the prior art are independent of the reference numerals of FIGS. 1 to 5 describing the present invention.) , One end of the through hole is connected to one end of the elastic tube accommodated in the housing 110, and the pressure transmission member 200 fixed to the outside of the housing 110 and installed has a through hole 230 therein, and is a conduit. It is connected to the tab of the container and is provided with a screw part 210 for maintaining the seal and a bolt head 220 installed on the upper part of the screw part 210 to facilitate screwing of the pressure transmission member 200. have.

Therefore, when installing the pressure gauge, generally, a Teflon tape is wound around the screw part 210 to ensure sealing, and the bolt head is turned with a wrench, etc. to screw the installation.

However, in the case of a structure such as the pressure gauge described above, it was inconvenient to adjust the position of the scale plate in a convenient direction. That is, when coupling by turning the gauge to the end of the screw portion 210 for screw coupling, the direction of the scale plate is determined depending on the length and number of tightening of the screw portion 210 .

This problem is a problem that occurs because the screw portion 210 of the pressure transmission member 200 and the pressure transmission passage 230 are integrally formed.

Accordingly, Utility Model Registration No. 20-0290588 discloses a gauge assembly structure that can solve the above problems.

As can be seen from the disclosed drawings, the registered utility model includes a cylindrical housing 110 accommodating an elastic tube 120 and a scale plate 130 , and the elastic tube 120 fixed to the outside of the housing 110 . ) is composed of a pressure transmitting member connected to one end of the elastic tube in order to transmit pressure to the inside.

And the pressure transmission pipe 150 constituting the pressure transmission member has a hollow cylindrical shape having a through hole 152, and the outer diameter is cut into a large-diameter portion in a region in contact with the fluid and a small-diameter portion close to the elastic tube 120. is formed. In addition, the large-diameter portion is tapered so that the diameter increases from the side in contact with the fluid.

In addition, the fastening member constituting the pressure transmitting member is loosely fitted in the small-diameter portion of the pressure transmitting pipe 150 , and a thread 141 is formed on a part of the outer periphery of the fastening member 140 , and the screw thread applies pressure. It is screwed with the connection tab of the pipe or container to be measured.

A bolt head 142 is formed in the outer diameter portion of the fastening member 140 from the portion where the thread 141 is formed to the side close to the elastic tube, so that the fastening member 140 is easily screwed.

Through this, it is possible to adjust the scale plate 130 of the pressure gauge in a direction convenient to read immediately after the screw thread 141 comes into contact with the end of the connection tab and before being completely tightened.

However, as can be seen in FIG. 6b , since the tapered part 151 protrudes from the end of the pressure transmission pipe 150, the hexagon nut-shaped fastening member is inserted into the pressure transmission pipe 150 housing 110. It cannot be assembled by passing through it, and since it is necessary to first insert the measuring body to which the elastic tube is connected, etc. to the rear plate of the housing, and then connect the pressure transmission pipe 150 by welding, etc., there is a disadvantage in that the assembling property is very poor.

That is, when the pressure transmission pipe 150 is integrally connected to the measuring body to which the elastic tube is connected, the pressure transmission pipe 150 is exposed so that the taper part 151 and the fastening member 140 are exposed to the rear of the housing 110 . Since it is impossible to assemble immediately by inserting the Since the space to perform the phase welding is very narrow and the operation takes a long time, the assembling property is inevitably deteriorated.

Accordingly, the present invention has been devised to solve the above problems,

An object of the present invention is to provide a gauge capable of improving assembling property by allowing the assembly to be assembled by directly inserting the assembly into the rear plate of the housing in a state in which the pipe portion into which the fastening member is fitted is first coupled to the rear surface of the body portion by welding or the like.

The fastening member is characterized in that it includes a hexagon nut.

Further, in the gauge according to the present invention,

The fastening member may further include a screw portion protruding toward the rear end of the hexagon nut portion.

a measurement unit 20 embedded in the mounting unit 11 and comprising a numerical display unit 21 and a numerical measurement unit 22; and

and a transmission member 30 for measurement connected to the rear end side of the numerical measurement unit 22 and coupled to pass through the assembly unit 13 .

The housing 10 has a cylindrical shape, the front is open and the rear is closed, and the assembly part 13 is drilled through the rear of the housing 10 .

In addition, the display window 12 is a transparent material that enables the external identification of the display unit 21 of the mounting unit 11 and is coupled to the front side of the housing 10 by a screw coupling method or the like.

The measurement unit 20 is to digitize the measurement object to be measured and displayed with a gauge, and to measure and display it.

The numerical display unit 21 is composed of a scale plate 211 and a needle 212 axially coupled to the center of the scale plate 211,

The measurement unit 22 includes an elastic tube 221 connected to a body portion provided with a body portion 31 of the measurement transmission member 30 to measure the degree of deformation of the elastic tube 221 with the needle 212 . ) so that the needle 212 is rotated to a specific value and displayed.

To this end, the measuring unit 22 transmits the rotating angle of the spring (not marked) and the elastic tube 221 to the needle 212 to rotate the needle 212 to the origin. include

When the pressure of the fluid is transmitted from the transmission member 30 for measurement, the measuring unit 20 rotates and deforms the elastic tube 221 at a predetermined angle in response to this, and thus the degree of deformation of the elastic tube 221 . is transferred to the needle 212 while being converted into rotational motion through the tooth bundle 222, and the pressure digitized through the pointer of the rotating needle 212 is displayed on the scale plate 211,

When the pressure applied to the transmission member 30 for measurement is relieved, the needle 212 returns to the zero position by the elastic force of the spring spring and rotates.

However, in the present specification, a pressure gauge has been representatively described for convenience of understanding, but the detailed structure of the measurement unit 20 may vary depending on a measurement target.

For example, in the case of a temperature gauge, a thermo-couple may be inserted into the measurement hole 322 of the transmission member 30 for measurement instead of the elastic tube 221 , and the display unit 21 may also have a needle ( 212) may be replaced by a digital method using a display unit instead of an analog method using the display unit.

Next, the core configuration of the present invention will be described.

The assembly part 13 includes a polygonal first assembly hole 131 and a polygonal second assembly hole arranged at a different angle from the first assembly hole 131 while overlapping the first assembly hole 131 in a concentric circle structure ( 132),

The transmission member 30 for measurement includes a body part 31 fitted into the first assembly hole 131 in a shape corresponding to the first assembly hole 131 and protruding backward from the rear surface of the body part 31 . The second assembling hole in a shape corresponding to the second assembling hole 132 and extrapolated to and rotatably coupled to the tube portion 32, which is connected to protrude and has a locking end 321 at the rear end thereof, and the second assembling hole A fastening member 33 passed through 132 and arranged at the rear of the housing 10 is included.

The first assembling hole 131 and the second assembling hole 132 are composed of polygons having different shapes,

In order to prevent the fixing of the measuring unit 20 and the overlapping of the shape of the body part 31 and the fastening member 33,

The first assembling hole 131 has a quadrangular shape, and the second assembling hole 132 has a hexagonal shape.

In addition, in order to change the direction of the housing 10 using the fastening member 33 and secure airtightness,

The fastening member 33 further includes a hexagon nut part 331 and a screw part 332 protruding toward the rear end of the hexagon nut part 331 .

Specifically, the body part 31 protrudes from the rear surface of the body part of the measuring part 22 to which the elastic tube 221 is connected in a rectangular parallelepiped shape, and due to the blocking protrusion (not marked) of the front (inner) edge, When inserted into the first assembly hole 131 , the rear end side of the body part 31 protrudes to the rear of the housing 10 and is fixed.

The body part 31 has an internal empty space so that the measurement hole 322 of the pipe part 32 is extended and connected, so that the pressure of the fluid is transmitted to the elastic tube 221 .

The pipe part 32 is connected to the body part 31 by having a measuring hole 322 penetrated in the longitudinal direction. to be transmitted to the elastic tube 221 .

The engaging end 321 is connected to protrude to have a larger outer diameter than the pipe part 32, and when the pipe part 32 is mounted on the connection tab T of a pipe or container, the end inside the connection tab T It adheres to (Ta) while being pressurized to secure airtightness to prevent leakage of fluid.

The fastening member 33 is in the form of a nibble consisting of a front end side hexagon nut part 331 and a rear end side screw part 332, and the hexagon nut part 331 has a width greater than the outer diameter of the screw part 332, and the A fitting hole 333 having an inner diameter greater than the outer diameter of the tube portion 32 is formed through in the longitudinal direction so that the fastening member 33 is freely rotatably coupled to the left and right on the tube portion 32 .

When the pipe part 32 is mounted on the connection tab T of the pipe line or container, the screw part 332 is screwed into the female thread part of the connection tab T, and the hexagon nut part The fastening member 33 is easily screwed into the 331 .

Therefore, as the fastening member 33 is tightened to the connection tab T, the locking end 321 is pressed by the screw portion 332 while in contact with the inner end Ta of the connection tab T and in close contact. As a result, fluid does not leak between the pipe part 32 and the connection tab T. At this time, before the fastening member 33 is completely tightened, the display part 21 can be rotated by holding the housing 10 and rotating the pipe part 32. The installation of the gauge can be completed with the direction of the gauge changed to a direction that is easy to identify.

And when the assembly of the housing 10 and the transmission member 30 for measurement, which is the core of the present invention, will be described,

First, the body part 31 and the pipe part 32 are separately manufactured, and then the fastening member 33 is inserted into the pipe part 32 .

In this state, by matching the measuring hole 322, the pipe part 32 is coupled to the rear surface of the body part 31 by welding or the like.

The assembled assembly is mounted on the mounting part 11 of the housing 10 together with the measurement unit 20 in a state in which the display window 12 is separated.

First, when the hexagon nut part 331 is rotated according to the direction of the second assembly hole 132 and inserted, the fastening member 33 passes through the assembly part 13 and is exposed to the rear of the housing 10 .

Then, holding the pipe part 32 and turning the body part 31 according to the direction of the first assembly hole 131 and inserting it, the body part 31 is fixed on the assembly part 13 .

In this state, when the display window 12 is assembled on the front surface of the housing 10 , the edge of the display unit 21 is pressed by the display window 12 , so that the body unit 31 is the first of the housing 10 . As the measurement unit 20 is closely attached to the rear surface of the housing 10 while being completely inserted into the assembly hole 131 , the assembly of the gauge is completed.

Therefore, in the present invention, unlike the prior art, since there is no need to weld the pipe part 32 in the state in which the body part 31 is assembled to the housing 10, the assembling property of the gauge can be significantly improved.

Meanwhile, in the present invention, after the hexagon nut part 331 is aligned with the second assembling hole 132 , the body part 31 should be aligned with the first assembling hole 131 again.

Accordingly, the present invention further includes an alignment means for aligning the hexagon nut portion 331 and the body portion 31 with the first and second assembly holes 131 and 132 .

As shown in FIG. 5 , the transmission member 30 for measurement includes the body part 31 and the hexagon nut part 331 when the fastening member 33 is extrapolated to the pipe part 32 . 1, and further comprising an alignment means to be aligned with the shape of the second assembling hole (131, 132).

The sorting means,

A ramp 323 protruding helically along the outer circumferential surface toward the front end of the pipe portion 32 at a specific position of the rear end of the tube portion 32 and connected in an inclined downward direction to form an inlet portion 323a at the front end;

and a guide protrusion 334 protruding from the inner circumferential surface (ie, fitting hole 333) of the front end of the hexagon nut portion 331 and passing through the inlet portion 323a,

When the guide protrusion 334 is positioned on the inlet part 323a , the body part 31 and the hexagon nut part 331 are arranged to correspond to the first assembly hole 131 and the second assembly hole 132 . characterized by being

The ramp 323 is a spiral formed by one rotation along the outer circumferential surface of the pipe part 32, and the upper and lower ends of the ramp 323 are disposed on the same line in the longitudinal direction of the pipe part 32, the fastening In a state in which the member 33 is coupled to the pipe part 32 , the guide protrusion 334 is caught on the ramp 323 .

The inlet portion 323a is opened to correspond to the width of the guide protrusion 334, and the inlet portion 323a is opened and formed at the lower end of the ramp 323. A protruding end 323b is formed in the longitudinal direction of the tube portion 32 .

At this time, the inlet portion 323a is formed at a specific position with respect to the body portion 31, wherein the formation position of the inlet portion 323a corresponds to the arrangement shape of the first and second assembling holes 131 and 132. Thus, the body part 31 and the hexagon nut part 331 are limited to the same arrangement position.

That is, when the guide protrusion 334 is positioned at the inlet part 323a, the body part 31 and the hexagon nut part 331 have the overlapping shape of the first and second assembly holes 131 and 132 and The ramp 323 and the inlet portion 323a are formed to be identically arranged.

And the guide protrusion 334 is connected to have a breaking part 334a on the connection part with the inner circumferential surface of the fitting hole 333. It is formed separately on the inner circumferential surface.

Therefore, before joining the body part 31 and the pipe part 32 by welding, the guide protrusion 334 is inserted into the inlet part 323a to couple the fastening member 33 to the pipe part 32, and then the body When the part 31 and the pipe part 32 are welded, the fastening member 33 is extrapolated to the pipe part 32 to complete the transmission member 30 for measurement.

In this state, when the measuring transfer member 30 (including the measuring unit 20) is turned over, the fastening member 33 is lowered by gravity, and at this time, the guide protrusion 334 moves to a predetermined position of the ramp 323. The fastening member 33 descends while rotating along the ramp 323 according to the lock, and the guide protrusion 334 stops on the inlet part 323a.

In this state, the housing 10 is turned over and inserted into the pipe part 32 to assemble the gauge. At this time, the body part 31 and the hexagon nut part 331 are connected to the first and second parts by the guide protrusion 334 . Since the two assembly holes 131 and 132 are arranged in the same way as the overlapping shape, when the operator rotates the housing 10 according to the body part 31 or the hexagon nut part 331 and assembles it, the body part 31 And since the assembly is completed while the hexagon nut part 331 passes through the assembly part 13 at a time, assembly is improved compared to working with the hexagon nut part 331 and the body part 31 separately. .

When the gauge assembled in this way is screwed by holding the hexagon nut part 331 with a spanner when it is mounted on the connection tab T, the guide protrusion 334 comes into contact with the ramp 323 and the breaking part ( 334a), the guide protrusion 334 is separated and the fastening member 33 is rotated to be screwed together.

In the above description of the present invention, the gauge has been mainly described with reference to the accompanying drawings, but the present invention is capable of various modifications, changes and substitutions by those skilled in the art, and such modifications, changes and substitutions are considered to be within the protection scope of the present invention. should be interpreted
