Description

Technical Field

[0001] The invention relates to the technical field of floor scale equipment, in particular to a column sensor for floor scales. Background Art

[0002] A floor scale, also known as a truck scale, is a large scale installed on the ground. It is usually used to measure the tonnage of cargo on a truck. It is the main weighing equipment used by factories, mines, businesses, etc. for measuring bulk goods. Floor scales can be divided into: I-beam floor scales, T-beam floor scales, L-beam steel floor scales, U-beam floor scales, channel steel floor scales, and reinforced concrete floor scales according to the scale structure; and can be divided into digital floor scales and analog floor scales according to the sensor type.

[0003] The column sensor is one of the commonly used sensors in the floor scale. During the measurement process, the gravity acts on the elastic body of the column sensor, causing the elastic body to deform, which is then converted into an electronic signal by the strain gauge on the elastic body and transmitted to the display device to display the weight. However, the column sensor must be kept in a vertical state during use to avoid tilting of the column sensor. The tilt of the column sensor will cause data errors in the weighing data, and since the floor scale and the column sensor are both used in an outdoor environment, the humidity and low temperature of the outdoor environment will also cause the column sensor to be unable to be used normally. Therefore, those skilled in the art have proposed a column sensor for floor scales to solve the above-mentioned technical problems. Summary of the Invention

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a column sensor for a floor scale, comprising a base, two movable grooves are equidistantly provided on both sides of the middle of the top of the base, and sliders are slidably connected in the movable grooves, the tops of the sliders on the same side are respectively fixedly connected to the front and rear sides of the middle of the bottom end of the movable seat, the side on which the movable seat is connected is fixedly connected to the lower ring seat, and the front and rear ends of the middle of the side away from the movable seat are provided with mounting holes, the middle of both sides of the top of the base are fixedly connected to the mounting seats, and the front and rear ends of the middle of the adjacent side of the mounting seat are fixedly connected to the mounting rod, and the end of the mounting rod away from the mounting seat is fixedly connected to a connecting block, and the middle of the side of the connecting block away from the mounting seat is respectively fixedly connected to one end of the corresponding strong spring, and the other end of the strong spring extends into the mounting holes at the corresponding positions, fixing holes are provided on both sides of the middle of the top of the base, and threaded holes are provided on one side of the middle of the top of the movable seat, and limiting bolts are threadedly connected in the threaded holes, and the bottom ends of the limiting bolts extend into the corresponding fixing holes.

[0006] Preferably, a fixing seat is fixedly connected to the middle of the rear side of the top end of the base, and slots are provided on the front and rear sides of the middle part of the fixing seat. The middle part of the top end of the movable seat on the same side is rotatably connected to one end of the diagonal support rod, and the other end of the diagonal support rod on the same side is rotatably connected to the middle part of the outer side of the upper ring seat. The middle part of the diagonal support rod is slidably connected to a sliding ring, and the outer side of the sliding ring is fixedly connected to one end of the horizontal insertion rod on the same side, and the other end of the horizontal insertion rod passes through the corresponding slots and extends outward. Several grooves are equidistantly provided on the middle end of the horizontal insertion rod away from the sliding ring, and a fixing bolt is threadedly connected to the middle part of the rear side of the fixing seat, and the end of the fixing bolt passes through the groove and the fixing seat in turn and extends outward.

[0007] Preferably, several fixing rods are equidistantly arranged in the middle and lower part of the bottom inner side of the base, and heating wires are provided on the fixing rods. A heat preservation cover is provided in the middle part of the bottom end of the base, and an insulation layer is provided on the outside of the heat preservation cover. The material of the insulation layer is rock wool.

[0008] Preferably, a mounting position is provided in the middle of the top of the base, a columnar sensor body is provided in the mounting position, a rubber layer is provided on the inner wall of the mounting position, and the material of the rubber layer is nitrile rubber.

[0009] Preferably, a grounding socket is provided at the front center of the top end of the base, and a grounding bolt is provided in the grounding socket.

[0010] Preferably, the four corners of the top end of the base are fixedly connected to support columns, and the four corners of the bottom end of the base are fixedly connected to bottom bosses.

[0012] Preferably, the longitudinal cross-sections of the sliders are all T-shaped, and the sliders match the moving grooves.

[0013] Working principle: When installing the column sensor body on the floor scale, the staff places the column sensor body in the installation position, and then moves the moving seat so that the slider at the bottom of the moving seat slides synchronously in the moving groove. The movement of the moving seat drives the inner wall of the lower ring seat to contact the middle and lower part of the column sensor body. At the same time, the connecting block on the mounting rod moves synchronously in the mounting hole of the moving seat. When the strong spring on the connecting block is squeezed and tightened, it simultaneously gives a reverse pushing force to the moving seat, so that the lower ring seat on the moving seat fixes the middle and lower part of the column sensor body more stably. Then, the limit bolt is installed in the threaded hole on the moving seat and the bottom of the limit bolt enters the fixing hole to fix the moving seat on the base. After fixing the middle and lower part of the column sensor body, rotate the diagonal support rod. When the diagonal support rod rotates, it drives the upper ring seat to rotate synchronously, and makes the inner wall of the upper ring seat contact the middle and upper part of the column sensor body. Then slide the sliding ring on the diagonal support rod. When the sliding ring moves, it drives the cross rod into the slot on the fixed seat. Finally, use the fixing bolt to limit and fix the cross rod in the fixed seat, so as to complete the fixation of the middle and upper part of the column sensor body. When the column sensor body is working, the heating wire on the fixed rod emits heat, and the heat is transferred to the column sensor body through the installation position, and the bottom of the column sensor body is insulated through the thermal insulation cover at the same time, to ensure the normal use of the column sensor body on the scale.

[0014] The present invention provides a column sensor for a floor scale. It has the following beneficial effects:

[0015] 1. The present invention fixes the upper and lower middle parts of the column sensor body in the base installation position through multiple fixed support facilities, ensuring the vertical state of the column sensor during use, avoiding the column sensor from tilting during use, improving the accuracy of the scale detection data, preventing data errors in the weighing data, and facilitating use by users.

[0016] 2. The present invention adds a fixing rod and a heating wire to the bottom of the column sensor body, which can ensure the normal temperature of the bottom of the column sensor when the column sensor body is in use, and simultaneously insulates the bottom of the column sensor through the heat insulation cover at the bottom, preventing the humid air and low temperature in the outdoor environment from causing the column sensor to malfunction, thereby improving the service life of the column sensor.

[0017] 3. The present invention avoids damage to the column sensor caused by lightning or other currents during thunderstorms by adding a grounding jack and a grounding bolt on the base, thereby ensuring the normal use of the column sensor. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example:

[0027] like Figure 1-6As shown, an embodiment of the present invention provides a column sensor for a floor scale, including a base 1, two movable grooves 15 are equidistantly provided on both sides of the middle of the top of the base 1, and sliders 31 are slidably connected in the movable grooves 15. The tops of the sliders 31 on the same side are respectively fixedly connected to the front and back sides of the middle of the bottom end of the movable seat 12, and the sides connected to the movable seat 12 are fixedly connected to the lower ring seat 8. The front and back ends of the middle of the side away from the movable seat 12 are provided with mounting holes 29. The middle of both sides of the top of the base 1 are fixedly connected to the mounting seat 2, and the front and back ends of the middle of the adjacent side of the mounting seat 2 are fixed. It is connected to a mounting rod 13, and a connecting block 27 is fixedly connected to the end of the mounting rod 13 away from the mounting seat 2. The middle of the side of the connecting block 27 away from the mounting seat 2 is fixedly connected to one end of the corresponding strong spring 28, and the other end of the strong spring 28 extends to the mounting hole 29 at the corresponding position. Fixed holes 20 are provided on both sides of the middle of the top of the base 1, and threaded holes 30 are provided on one side of the middle of the top of the movable seat 12. The threaded holes 30 are threadedly connected to the limiting bolts 14, and the bottom ends of the limiting bolts 14 extend to the inside of the corresponding fixing holes 20.

[0028] When fixing the middle and lower part of the columnar sensor body 5, the staff moves the moving seat 12 so that the slider 31 at the bottom of the moving seat 12 slides synchronously in the moving groove 15. The movement of the moving seat 12 drives the inner wall of the lower ring seat 8 to contact the middle and lower part of the columnar sensor body 5. At the same time, the connecting block 27 on the mounting rod 13 moves synchronously in the mounting hole 29 of the moving seat 12. When the strong spring 28 on the connecting block 27 is squeezed and tightened, it simultaneously gives the moving seat 12 a reverse pushing force, so that the lower ring seat 8 on the moving seat 12 fixes the middle and lower part of the columnar sensor body 5 more stably. Then, the limiting bolt 14 is installed in the threaded hole 30 on the moving seat 12 and the bottom of the limiting bolt 14 enters the fixing hole 20 to fix the moving seat 12 on the base 1.

[0029] The material of the strong spring 28 is high-carbon stainless steel. When the strong spring 28 made of this material is used in an external humid environment, the surface of the spring is not easily corroded and damaged, while the elasticity of the strong spring 28 is guaranteed, and the service life is long, and the spring does not need to be replaced frequently.

[0030] The middle part of the rear side of the top end of the base 1 is fixedly connected to a fixed seat 17, and slots 16 are provided on the front and back sides of the middle part of the fixed seat 17. The middle part of the top end of the movable seat 12 on the same side is rotatably connected to one end of the diagonal support rod 6, and the other end of the diagonal support rod 6 on the same side is rotatably connected to the middle part of the outer side of the upper ring seat 4. The middle part of the diagonal support rod 6 is slidably connected to a sliding ring 18, and one side of the outer side of the sliding ring 18 is fixedly connected to one end of the horizontal insertion rod 3 on the same side, and the other end of the horizontal insertion rod 3 passes through the corresponding slots 16 and extends outward. Several grooves 26 are equidistantly provided on the middle end of the horizontal insertion rod 3 away from the sliding ring 18. A fixing bolt 19 is threadedly connected to the middle part of the rear side of the fixed seat 17, and the end of the fixing bolt 19 passes through the groove 26 and the fixed seat 17 in turn and extends outward.

[0031] When fixing the middle and upper part of the columnar sensor body 5, rotate the diagonal support rod 6. When the diagonal support rod 6 rotates, it drives the upper ring seat 4 to rotate synchronously, and makes the inner wall of the upper ring seat 4 contact with the middle and upper part of the columnar sensor body 5. Then slide the sliding ring 18 on the diagonal support rod 6. When the sliding ring 18 moves, it drives the cross rod 3 to enter the slot 16 on the fixing seat 17. Finally, use the fixing bolt 19 to limit and fix the cross rod 3 in the fixing seat 17, thereby completing the fixation of the middle and upper part of the columnar sensor body 5.

[0032] Several fixing rods 22 are equidistantly arranged in the middle and lower part of the bottom inside the base 1, and heating wires 23 are arranged on the fixing rods 22. A heat preservation cover 11 is arranged in the middle of the bottom end of the base 1, and an insulation layer is arranged on the outside of the heat preservation cover 11. The material of the insulation layer is rock wool.

[0033] While the column sensor body 5 is working, the heating wire 23 on the fixing rod 22 emits heat, which is transferred to the column sensor body 5 through the mounting position 21, and the bottom of the column sensor body 5 is simultaneously insulated through the thermal insulation cover 11, thereby ensuring the normal use of the column sensor body 5 on the scale. The thermal insulation cover 11 made of rock wool is less affected by the moisture in the air when used in an external environment, and the thermal insulation cover 11 made of rock wool has a better thermal insulation effect.

[0034] An installation position 21 is provided in the middle of the top of the base 1, and a column sensor body 5 is provided in the installation position 21. A rubber layer is provided on the inner wall of the installation position 21. The material of the rubber layer is nitrile rubber. The rubber layer of nitrile rubber can increase the stability of the column sensor body 5 in the installation position 21 during installation, prevent the column sensor from tilting during use, and ensure the normal use of the column sensor on the floor scale.

[0035] A grounding socket 24 is provided at the front middle part of the top of the base 1, and a grounding bolt 10 is provided in the grounding socket 24. Adding the grounding socket 24 and the grounding bolt 10 to the base 1 prevents damage to the column sensor caused by lightning or other currents during thunderstorms, thereby ensuring the normal use of the column sensor.

[0036] Support columns 7 are fixedly connected to the four corners of the top end of the base 1, and bottom bosses 9 are fixedly connected to the four corners of the bottom end of the base 1. The support columns 7 on the base 1 can support and protect the device on the entire base 1 and the columnar sensor body 5 in the installation position 21, and the bottom boss 9 at the bottom end of the base 1 can increase the stability of the base 1 during use and increase the grip of the bottom end of the entire device.

[0037] A rubber pad layer 25 is provided on the inner side of the upper ring seat 4 and the lower ring seat 8. The material of the rubber pad layer 25 is butyl rubber. By adding the rubber pad layer 25 in the upper ring seat 4 and the lower ring seat 8, the contact friction between the inner wall of the upper ring seat 4 and the lower ring seat 8 and the columnar sensor body 5 is improved. In addition, the rubber pad layer 25 made of butyl rubber has good wear resistance and a long service life.

[0038] The longitudinal cross-section of the slider 31 is T-shaped, and the slider 31 matches the movable groove 15. The matching slider 31 and movable groove 15 increase the stability of the movable seat 12 when moving on the base 1, and the T-shaped slider 31 will not fall off when sliding in the movable groove 15, which is convenient for users to use.

[0039] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
