[0031] The measuring rod 1 is a vertically arranged tubular structure so that the measuring rod 1 can be filled with liquid 16. The upper end of the measuring rod 1 has a first top plate to close the upper end of the measuring rod 1. The upper part of the measuring rod 1 has a first vent hole to balance the air pressure above the liquid surface in the measuring rod 1 with the air pressure outside the measuring rod 1, so that the liquid 16 in the measuring rod 1 can flow as quickly as possible. The upper end of the above-mentioned measuring rod 1 is used to support the bottom of the plate.

[0032] The first U-shaped buckle 2 is disposed on the outer side wall of the measuring rod 1 with its opening downward, so that the measuring rod 1 can be fixed on a tower ruler through the first U-shaped buckle 2 .

[0033] The first connecting tube 3 is a vertically arranged tubular structure. The upper end of the first connecting tube 3 is connected to the lower end of the measuring rod 1.

[0034] The reference rod 4 is a vertically arranged tubular structure so that the reference rod 4 can be filled with liquid 16. The upper end of the reference rod 4 has a second top plate to close the upper end of the reference rod 4. The upper part of the reference rod 4 has a second vent hole to balance the air pressure above the liquid surface in the reference rod 4 with the air pressure outside the reference rod 4, so that the liquid 16 in the measuring rod 1 flows as quickly as possible. The upper end of the reference rod 4 is used to press against the bottom of the plate.

[0035] The second U-shaped buckle 5 is disposed on the outer side wall of the reference rod 4 with its opening downward, so that the reference rod 4 can be fixed on another tower ruler through the second U-shaped buckle 5 .

[0036] The second connecting pipe 6 is a vertically arranged tubular structure. The upper end of the second connecting pipe 6 is communicated with the lower end of the reference rod 4.

[0037] The two ends of the hose 7 are connected to the lower end of the first connecting pipe 3 and the lower end of the second connecting pipe 6 respectively, and form a U-shaped structure. The hose 7 is a pressure-proof hose 7. The hose 7 and the measuring rod 1 and the reference rod 4 are filled with liquid 16. At this time, the liquid 16 is not filled. The liquid 16 is an antifreeze liquid 16.

[0038] The first floating block 8 floats on the liquid surface in the measuring rod 1. The first floating block 8 has a base block and a projection. The base block and the projection are both made of light floating blocks. The projection is protrudingly arranged on the upper part of the base block.

[0039] The second float 9 floats on the liquid surface in the reference rod 4. The second float 9 is made of a light float. The weight of the second float 9 is equal to that of the first float 8, so that the second float 9 and the first float 8 are at the same level.

[0040] The power supply 10 is arranged on the measuring rod 1 .

[0041] The indicator light 11 is arranged on the outer side wall of the measuring rod 1. The indicator light 11 is connected to the power supply 10 to form a circuit. There are multiple indicator lights 11, and each indicator light 11 is connected in parallel. Each indicator light 11 is arranged in a vertical direction, and the arrangement order is the same as the arrangement order of the corresponding circuit contacts.

[0042] The switch 12 is arranged on the outer side wall of the measuring rod 1. The switch 12 is connected to the circuit and is connected in series with each indicator light 11. When the switch 12 is turned on and any indicator light 11 is lit, it indicates that the circuit where the indicator light 11 is located is normal.

[0043] The contact 13 is arranged on the first floating block 8. Optionally, the contact 13 is a component of the first floating block 8, and the weight of the contact 13 is included in the weight of the first floating block 8. Also optionally, the contact 13 and the first floating block 8 are two structures, and the weight of the contact 13 is not included in the weight of the first floating block 8. In this case, the weight of the contact 13 is relatively light. The contact 13 includes a conductive contact. The conductive contact is protrudingly arranged on the side of the protrusion.

[0044] The contact 14 is arranged on the measuring rod 1, and is arranged horizontally corresponding to the contact 13 when the upper end of the measuring rod 1 and the upper end of the reference rod 4 are on the same horizontal plane, so as to obtain the height deviation between the contact 13 and the contact 14 by respectively pressing the measuring rod 1 and the reference rod 4 against the bottom of the board, and judge the height deviation between the bottom of the board at the measuring rod 1 and the bottom of the board at the reference rod 4. The contact 14 includes a circuit contact. The circuit contact is arranged on the inner side wall of the measuring rod 1.

[0045] The circuit contact is connected to the circuit and connected in series with the indicator light 11. The circuit contact contacts the corresponding conductive contacts arranged in the horizontal direction and conducts the circuit. There are multiple circuit contacts, and each circuit contact is arranged at a set distance in the vertical direction. The set distance is 0.5 mm. Each circuit contact is connected in series with each indicator light 11.

[0046] Optionally, the circuit contact includes a first electrical connection point and a second electrical connection point which are arranged on the same horizontal plane at a certain distance. Under the above conditions, the first electrical connection point and the second electrical connection point are respectively connected to the two ends of the set point on the line between the switch 12 and the indicator light 11 and / or the two ends of the set point on the line between the power supply 10 and the indicator light 11, so as to realize that the circuit contact is connected to the circuit and connected in series with the indicator light 111, and the circuit contact contacts the corresponding conductive contacts arranged in the horizontal direction and conducts the circuit. Among them, when the first electrical connection point and the second electrical connection point are respectively connected to the two ends of the set point on the line between the switch 12 and the indicator light 11, the circuit is as follows: Fig.10 When the first electrical connection point and the second electrical connection point are connected to the two ends of the circuit set between the switch 12 and the indicator light 11 and the two ends of the circuit set between the power supply 10 and the indicator light 11, the circuit is as shown. Fig.11 shown.

[0047] Optionally, the circuit contact is an electrical connection point. Under the above conditions, the circuit contact and the conductive contact are respectively connected to the two ends of the set point on the line between the switch 12 and the indicator light 11 and / or the two ends of the set point on the line between the power supply 10 and the indicator light 11, and the circuit contact is set at the end of the line where the indicator light 11 is located, so that the circuit contact is connected to the circuit and connected in series with the indicator light 111, and the circuit contact contacts the corresponding conductive contacts set in the horizontal direction and conducts the circuit. Among them, when the circuit contact and the conductive contact are respectively connected to the two ends of the set point on the line between the switch 12 and the indicator light 11, the circuit is as follows: Fig.12 When the circuit contacts and the conductive contacts are respectively connected to the two ends of the circuit set between the switch 12 and the indicator light 11 and the two ends of the circuit set between the power supply 10 and the indicator light 11, the circuit is as shown in FIG. Fig.13 shown.

[0048] The limiting protrusion 15 is protrudingly arranged on the inner side wall of the measuring rod 1 and is arranged just above and / or below each circuit contact. Optionally, the first top plate is arranged just above each circuit contact to form a limiting protrusion 15, and a protrusion is arranged below each circuit contact to form another limiting protrusion 15. When the limiting protrusion 15 contacts the upper part of the conductive contact, the conductive contact contacts the uppermost circuit contact, and when the limiting protrusion 15 contacts the lower part of the conductive contact, the conductive contact contacts the lowermost circuit contact.

[0049] Through the above arrangement, the conductive contact contacts all the circuit contacts, and all the indicator lights 11 are on. If the top of the measuring rod 1 and the reference rod 4 are not on the same horizontal plane due to the elevation deviation of the bottom of the board, the first floating block 8 and the second floating block 9 will remain horizontal under the action of the liquid 16, which will cause the conductive contact and the circuit contact to have a relative displacement, causing some indicator lights 11 to fail to light up, thereby confirming the relative deviation between the measuring rod 1 and the top of the reference rod 4. For every 1mm increase in the height deviation between the measuring rod 1 and the top of the reference rod 4, the relative displacement between the conductive contact and the circuit contact increases by 0.5mm. When the measuring rod 1 is higher than the reference rod 4, for every 1mm increase in the height deviation, the conductive contact drops 0.5mm relative to the circuit contact, and the indicator lights 11 turn off one light from top to bottom. Therefore, for every light that turns off from top to bottom, the bottom of the board at the measuring rod 1 is 1mm higher than the bottom of the board at the reference rod 4. When the measuring rod 1 is lower than the reference rod 4, for every 1mm increase in height deviation, the conductive contact rises 0.5mm relative to the circuit contact, and the indicator light 11 turns off one light from bottom to top. Therefore, for every light that turns off from bottom to top, the bottom of the board at the measuring rod 1 is 1mm lower than the bottom of the board at the reference rod 4. In addition, during measurement, the top or bottom light will remain lit, so when only one light is on, it indicates that the elevation deviation between the bottom of the board at the measuring rod 1 and the bottom of the board at the reference rod 4 is too large, and correction is required for easy observation.

[0050] When the board bottom height deviation measuring tool of the present invention is used, the measuring rod 1 and the reference rod 4 are fixed on two tower rulers through the first U-shaped buckle 2 and the second U-shaped buckle 5 respectively, and the switch 12 is turned on. When any indicator light 11 is on, it indicates that the circuit is normal. The measuring rod 1 and the reference rod 4 are placed on the board bottom, and the indicator light 11 is observed. When the indicator light 11 is stable, the reading is performed. Among them, when a light is turned off from top to bottom, the board bottom at the measuring rod 1 is 1mm higher than the board bottom at the reference rod 4, and when a light is turned off from bottom to top, the board bottom at the measuring rod 1 is 1mm lower than the board bottom at the reference rod 4.
