FIG. 7 is a cross-sectional side view of a portable hand press for preparing an XRF measurement sample according to still another embodiment of the present invention.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a cross-sectional side view of a portable hand press for preparing an XRF measurement sample according to a preferred embodiment of the present invention.

  As shown in FIG. 1, a portable hand press (hereinafter also referred to as a “hand press”) 100 for preparing an XRF measurement sample according to a preferred embodiment of the present invention includes a base 102 that forms a lower part, The body portion 104 is formed to extend upward from one side by a certain distance, and the upper portion 106 is formed to extend horizontally from the body portion 104 corresponding to the base portion 102.

  Further, a groove 150 in which a cup 155 for carrying an XRF measurement sample (200, see FIG. 3) is included is formed on the upper surface of the base 102.

  Here, the cup 155 and the groove 150 are formed in a circular shape.

  In the present invention, it is determined that the configuration in which the cup 155 and the groove 150 are formed in a circular shape is most desirable from the viewpoint of easy manufacture, but any person who has ordinary knowledge in the technical field of the present invention may be used. The cup 155 and the groove 150 may not be circular, but may be square or polygonal such as square.

  In particular, when the cup 155 and the groove 150 are polygonal shapes such as a square or a square, formation of a lattice plate (160, see FIG. 3) or a lattice (170, see FIG. 5) described later becomes easier. Can be expected.

  In the case where the cup 155 and the groove 150 are formed in a circular shape, the measurement region of the pressed measurement sample can be formed more closely in view of the occurrence of a zone in which some measurement on the outside is not possible. More desirable.

  Meanwhile, it is preferable that the cup 155 is detachably formed in the groove 150 in order to easily discard the measured sample.

  The upper portion 106 extends horizontally from the body portion 104 corresponding to the base portion 102, and includes a main pressure shaft 120 for pressing the XRF measurement sample 200, and the main pressure shaft 120. A pressure limiting shaft 130 for adjusting the pressure depth is formed.

  In addition, the main pressure shaft 120 formed in the upper portion 106 preferably extends through an upper through hole 122 formed so as to penetrate the upper portion 106 downward.

  A handle 110 is formed at the upper end of the main pressurizing shaft 120 to allow a researcher / experimenter to move the main pressurizing shaft 120 up and down.

  In the present invention, in order to control the movement of the main pressurizing shaft 120, the structure of the handle portion 110 is adopted. However, even if a lever structure is adopted as in the case of a normal hand press, the main addition shaft is used. Of course, the vertical movement of the pressure shaft 120 can be controlled.

  A spring 121 is formed on the surface of the main pressure shaft 120 as shown in the drawing.

  The spring 121 is formed for the purpose of returning to the original position by the reaction of the spring 121 after the main pressure shaft 120 is lowered when the handle portion 110 is pressed.

  Therefore, when a researcher / experimenter presses the handle portion 110, the main pressure shaft 120 moves correspondingly to the inside of the upper through hole 122, and the main pressure shaft 120 moves downward. Will move.

  In addition, it is preferable that a margin space corresponding to the spring 121 is formed on the inner wall of the upper through hole 122.

  Furthermore, it is more desirable that a stopper (not shown) for restricting the downward movement of the spring 121 is formed inside the upper through hole 122 at the lower end where the spring 121 is provided.

  Here, as described above, the pressure limiting shaft 130 for controlling the pressure depth of the main pressure shaft 120 or the vertical movement distance is formed on the upper portion 106.

  At this time, as shown in FIG. 1, the formation position of the pressurizing restriction shaft 130 is provided on the rear side (right side as viewed from the drawing) of the main pressurizing shaft 120. In contrast to this, the operator / experimenter's hand press 100 may be provided on the front side (left side as viewed from the drawing) of the main pressurizing shaft 120.

  In order to assist the vertical movement of the pressure limiting shaft 130, it is preferable that a spring 131 is formed on the surface of the pressure limiting shaft 130.

  At this time, it is preferable that the elastic force of the spring 131 is the same as the elastic force of the spring 121 formed on the main pressure shaft 120 or has a weaker level of elastic force.

  Further, in order to synchronize the vertical movement of the main pressure shaft 120 and the pressure limit shaft 130, the lower portion of the upper end portion 115 of the main pressure shaft 120 and the uppermost end of the pressure limit shaft 130 are mutually connected. Connecting plates 138 to be connected are provided and fixed to each other.

  Therefore, when the main pressure shaft 120 moves up and down by the operation of the handle portion 110, the main pressure shaft 120 and the pressure limit shaft 130 are interconnected by the connecting plate 138. The moving distance between the main pressure shaft 120 and the pressure limit shaft 130 may be synchronized with each other.

  In FIG. 1, reference numeral 132 denotes a bolt for fixing the other end of the connecting plate 138 having one end connected to the main pressure shaft 120 to the uppermost end of the pressure limiting shaft 130.

  In FIG. 1, reference numeral 135 is for restricting the vertical movement distance in the pressure limiting shaft insertion hole 134 in which the pressure limiting shaft 130 is the upper portion 106 and one end formed in the upper portion 106 is closed. It is a detent part.

  That is, the pressure limiting shaft 130 is inserted only in a part of its length into the pressure limiting shaft insertion hole 134 of the pressure limiting shaft 130 formed in the upper portion 106, that is, the main pressure shaft 120. However, the upper portion 106 is different from moving up and down completely through the upper through hole 122.

  At this time, the fixed position of the rotation stopper 135 is set in consideration of the vertical movement distance of the pressure limiting shaft 130.

  Further, it is desirable that a set screw 137 is further formed to fix the rotation preventing part 135 itself on the pressure limiting shaft 130.

  The detent portion 135 can be fixed to a certain region of the pressure limiting shaft 130 by the set screw 137.

  It is desirable that a stopper (not shown) for restricting the downward movement of the spring 131 is further provided in the pressure limiting shaft insertion hole 134.

  The stopper functions to limit the downward compression of the spring 131 formed on the pressure limiting shaft 130.

  On the other hand, the reason why the pressure limiting shaft 130 is fixed to a certain region will be described later with reference to FIG.

  A pressing disk 140 is formed at the lower end of the main pressure shaft 120.

  The pressing disk 140 is preferably formed in a circular shape. However, as described above, when the cup 155 and the groove 150 are formed in a square shape or a rectangular shape, the pressing disk 140 is also a rectangular shape or a rectangular shape. It is desirable to form.

  In the hand press 100 shown in FIG. 1, the researcher / experimenter first holds the XRF measurement sample 200 on the cup 155 inserted into the groove 150.

  Here, it is desirable that the XRF measurement sample 200 to be carried is a sample that has been pulverized in advance on site.

  In addition, the grinding can be performed using a suitable grinding device, for example, a mill, but the description regarding this departs from the scope of the present invention, so that a specific grinding mechanism, grinding device, or grinding is performed. A description of the method will be omitted.

  This is in order to prevent the side effect of obtaining completely different measurement results depending on the measurement position when a portable XRF measuring device is directly applied to a sample to be subjected to non-destructive analysis at an exploration site. .

  After the crushed XRF measurement sample 200 is carried on the cup 155 of the groove 150, the handle portion 110 is rotated to rotate the main pressure shaft 120 so as to move downward. The pressing disk 140 formed at the lower end of 120 presses the XRF measurement sample 200 carried on the cup 155 of the groove 150.

  Here, as can be seen from the figure, since the width of the pressing disk 140 is wider than the width of the cup 155, the pressing disk 140 presses the XRF measurement sample 200, so that the entire sample 200 is uneven. There is a risk that it will not be possible to press.

  Therefore, it is preferable that the XRF measurement sample 200 carried on the cup 155 is carried higher than the height of the cup 155.

  In this case, since it is difficult to accurately maintain the amount of the XRF measurement sample 200 carried on the cup 155, a protrusion 145 is formed at the lower end of the pressing disk 140 as shown in FIG. It became a thing.

  However, as shown in FIG. 2, a grid plate (160, see FIG. 3) is placed on the XRF measurement sample 200 carried by the cup 155 in FIG. It can also be arranged.

  Here, in order to appropriately fix the position of the grid plate 160, an appropriate fixing device (not shown) corresponding to the grid plate 160 can be disposed on the base 102, and the technology of the present invention. Anyone who has ordinary knowledge in the field can easily implement such a fixing device, and the description thereof will be omitted.

  FIG. 2 is a side sectional view of a portable hand press for preparing an XRF measurement sample according to another preferred embodiment of the present invention.

  As can be seen from FIG. 2, a protrusion 145 is formed at the lower end of the pressing disk 140.

  At this time, it is preferable that the protrusion 145 has a diameter that can be inserted into the cup 155 included in the groove 150 of the base 102.

  In addition, it is preferable that the protruding portion 145 is formed of a material that is difficult for external foreign matter to adhere to, for example, stainless steel.

  Here, the protrusion 145 not only prevents contamination of the external foreign matter, but also in the subsequent measurement, in order to eliminate the adverse effect of the previous measurement sample, it is particularly preferable that the protrusion 145 is formed of a material that can be easily cleaned. desirable.

  If necessary, the entire hand press 100 device can be made of a light material such as plastic for ease of carrying.

  This can be expected to have a further effect that easy accessibility to the exploration site can be ensured.

  As shown in FIG. 2, the height (h1) of the protruding portion 145 and the height (h2) of the cup 155 included in the groove 150 formed in the base portion 102 are expressed by Equation 1. It is preferable to satisfy the relationship.

  This is because when a small amount of sample is available at the exploration site, even a small amount of sample 200 can be pressed sufficiently.

  Next, FIG. 3 is an enlarged side sectional view showing a part of the portable hand press for preparing the XRF measurement sample in FIG.

  As can be seen from FIG. 3, after the XRF measurement sample 200 is carried, a lattice plate 160 is further provided on the XRF measurement sample 200.

  The lattice plate 160 will be described in detail with reference to FIG.

  From FIG. 3, the cup 155 is positioned in the groove 150 formed in the base 102, and after supporting the XRF measurement sample 200, the main pressure shaft 120 is moved downward to press the XRF measurement sample 200, A lattice plate 160 is disposed on the pressed XRF measurement sample 200.

  For a description of the grid plate 160 according to a preferred embodiment of the present invention, reference is made to FIG.

  FIG. 4 is a plan view of a lattice plate inserted into the groove of the portable hand press for preparing the XRF measurement sample of FIG.

  As can be seen from FIG. 4, the lattice plate 160 is formed in a circular shape, but is not limited to a circular shape.

  The lattice plate 160 is divided into a plurality of lattice cells 165 therein.

  The size of the lattice cell 165 is not limited to a sample size required by a portable XRF measuring instrument, for example, a size of 2 mm on all sides.

  If necessary, other polygonal shapes such as rectangles may be formed instead of squares.

  In FIG. 4, a lattice plate reference point 162 for designating the orientation of the lattice plate 160 is formed on the lattice plate 160.

  The grid plate reference point 162 is used to set a reference position of the grid plate 160 when the grid plate 160 is included in the cup 155, and is adjacent to the non-destructive analysis at the exploration site. It serves as a reference for avoiding confusion about whether or not to measure with the lattice cell 165.

  That is, the non-destructive analysis in the lattice cell 165 can be sequentially performed from the left side to the right side starting from the left side of the uppermost end of the lattice plate 160 shown in FIG. In such a non-destructive analysis, it is possible to prevent the lattice cells 165 from being confused and duplicated, or to prevent the lattice cells 165 from dropping out of the analysis.

  In addition, the lattice plate 160 is preferably formed in any shape of a square, a rectangle, and a rhombus.

  At the same time, it is desirable that the grid cells 165 forming the grid plate 160 have the same width, and this is advantageous in that the measurement values in the grid cells 165 are uniform in the field survey. There is.

  In FIG. 4, the height of the lattice plate 160 is not shown, but the lattice plate 160 has a certain height, for example, 2 mm.

  As described above, since the lattice plate 160 has a certain height, it is desirable to fix the pressure limiting shaft 130 in a certain region as described above.

  In other words, if the pressure limiting shaft 130 is not fixed in a certain region, the grid plate 160 may be destroyed if the main pressure shaft 120 is excessively moved downward.

  Even if the grid plate 160 is made of a stainless steel material so as to withstand the pressure applied by the main pressure shaft 120, the durability is easily damaged.

  Therefore, if the pressure limiting shaft 130 is fixed in a certain region, excessive pressure is not applied to the lattice plate 160 even if the main pressure shaft 120 moves downward to the maximum. .

  Like the protrusion 145, the lattice plate 160 is preferably formed on a material that can be easily cleaned in order to prevent contamination by external foreign matters and eliminate the adverse effects of the previous measurement sample. Freely formed.

  Next, FIG. 5 is a schematic perspective view showing a lattice formed on a protruding portion of a pressing disk in a portable hand press for preparing an XRF measurement sample according to still another preferred embodiment of the present invention.

  FIG. 5 differs from FIGS. 1 to 4 in that the grid 170 is formed directly on the pressing disk 140.

  The lattice 170 in FIG. 5 is formed on the lower surface of the pressing disk 140 and can be formed in contact with the pressing disk 140 as shown in FIG. 2 and as shown in FIGS. The protrusion 145 may be formed and then formed on the surface of the protrusion 145.

  In this case, even when the lattice 170 is formed on the surface of the protruding portion 145, it is most desirable that the protruding portion 145 is detachable for reasons such as cleaning as described above.

  In FIG. 5, the lattice 170 may include a lattice cell 175, which is substantially the same as the lattice cell 165 in FIG. 4, and a detailed description thereof will be omitted.

  The grid 170 in FIG. 5 is preferably divided into grid walls 177, and the height of the grid wall 177 is more preferably the same as the height of the grid plate 160 of FIG.

  Here, the height of the lattice 170, that is, the height of the lattice wall 177 must be lower than the height (h2) of the cup 155.

  In addition, the grid 170 is formed of a material that can be easily cleaned in order to prevent the contamination of external foreign matters and eliminate the adverse effects of the previous measurement sample, as with the protrusion 145 and the grid plate 160 described above. For this purpose, it is formed to be detachable.

  In addition, since the shape of the lattice 170 is the same as the shape of the lattice plate 160 described above, description of the shape of the lattice 170 is also omitted.

  Next, another embodiment of the grating 170 in FIG. 5 will be described with reference to FIG.

  FIG. 6 is a cross-sectional view of another aspect of the grating in FIG.

As shown in FIG. 6, a protruding pin 178 is formed at the center of the lattice cell 175 in the lattice 170. The protruding pin 178 is located at the approximate center in the lattice cell 175 and is portable. The XRF measuring device is used as a reference position for irradiating X-rays.

  That is, the protruding pin 178 displays the measurement reference position of the lattice pattern formed on the surface of the measurement sample 200, and the researcher / experimenter refers to the measurement reference position appearing on the protruding pin 178. Thus, XRF measurement at the corresponding position can be easily performed.

  In FIG. 6, reference numeral 172 corresponds to the configuration of the grid plate reference point 162 of FIG.

  Finally, a portable hand press 300 for preparing an XRF measurement sample according to still another embodiment of the present invention will be described.

  FIG. 7 is a cross-sectional side view of a portable hand press for preparing an XRF measurement sample according to still another embodiment of the present invention.

  The simple hand press 300 shown in FIG. 7 has almost the same configuration as that of the simple hand press 100 in FIG. 1, but the configuration of the pressure limiting shaft 130 in FIG. 1 is relatively simple. It is characterized by that.

  From FIG. 7, the pressure limiting shaft 180 is partially inserted into the pressure limiting shaft insertion hole 184, and unlike FIG. 1, the configuration of the connecting plate 138 is unnecessary.

  Instead, in FIG. 7, a head portion 182 is formed at the upper end of the pressure limiting shaft 180.

  Further, unlike the spring 131 formed on the surface of the pressure limiting shaft 130 in FIG. 1, it is preferable that the pressure limiting shaft 180 is formed with a thread 181.

  Here, unlike the spring 131 in FIG. 1, the thread 181 in FIG. 7 moves downward in conjunction with the pressurizing restriction shaft 180 when the main pressurizing shaft 120 moves downward. It is not a configuration.

  However, the pressure limit shaft 180 may be sufficiently inserted into the pressure limit shaft insertion hole 184 in consideration of the pressure depth that changes depending on the height change of the groove 150 or the cup 155. It is desirable to form 181 up to the lowest end of the pressure limiting shaft 180.

  Meanwhile, the head part 182 is preferably formed to be within a radius range of the handle part 110.

  Therefore, when the operation such as pressing the handle part 110 is performed, the main pressure shaft 120 moves downward, and at this time, a part of the handle part 110 strikes the head part 182, The moving distance of the main pressurizing shaft 120 downward is appropriately limited.

  The reason for limiting the downward movement distance of the main pressure shaft 120 is as described above.

  In particular, in FIG. 7, unlike the anti-rotation part 135 of FIG. 1, the stop bolt 185 fixed on the upper surface of the upper part 106 was formed.

  As described above, when the set bolt 185 is formed on the upper end surface of the upper portion 106, the movement distance of the pressure limiting shaft 180 can be more easily limited.

  Therefore, unlike FIG. 1, the set screw 137 is unnecessary, and other components such as the connecting plate 138 are also unnecessary, which is suitable not only for convenience of operation but also from the viewpoint of durability. is there.

  The preferred embodiments of the present invention have been described with reference to some embodiments. However, such descriptions are merely examples, and the present invention is not limited thereby, and the technical field to which the present invention belongs Those skilled in the art will appreciate that the present invention can be implemented with various variations and modifications from the above description, or can be practiced equivalent to the present invention. .
