Description

Technical Field

[0001] This utility model belongs to the field of pressure sensor technology, specifically a sensor anti-offset wheel spoke type elastomer. Background Technology

[0002] Its shape resembles a wheel, with multiple spokes connecting the central hub to the outer rim. This structural layout allows force to be distributed relatively evenly through the spokes when under load, effectively avoiding stress concentration. For example, in some industrial load cells, when a heavy object is placed above the sensor, the spokes can evenly distribute the weight to various parts of the elastic body, ensuring the accuracy and stability of the measurement. Due to its special structural geometry and mechanical design principles, when the load application point deviates from the center position, the elastic body can still use its own structural deformation coordination mechanism to produce relatively balanced strain changes in various strain-sensitive areas, thereby ensuring that the deviation of the sensor output signal is within an acceptable range.

[0003] The existing technology still has the following shortcomings:

[0004] 1. Existing sensor anti-offset load spoke elastomers have the problem of complicated installation methods during use. In traditional technology, the installation of sensor anti-offset load spoke elastomers is relatively complicated, which is not conducive to improving work efficiency.

[0005] 2. The existing anti-offset load spoke elastomer of the sensor still has the problem of inconvenient maintenance during use. When the anti-offset load spoke elastomer of the sensor fails and maintenance is required, the disassembly process is relatively complicated, time-consuming and the maintenance efficiency is low. Utility Model Content

[0006] To overcome the above-mentioned defects, this utility model provides a sensor anti-eccentricity spoke-type elastomer, which solves the problem of complicated installation and disassembly processes.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sensor anti-eccentric load spoke-type elastomer, including a force-bearing block, a plurality of shear beams are distributed in a ring around the outer side of the force-bearing block, a support block is provided at the end of the shear beam away from the force-bearing block, a plurality of fixing blocks are fixedly connected to the outer side of the support block, the fixing blocks are evenly distributed in a ring around the outer side of the support block, and a rotating disk is provided below the fixing blocks.

[0008] As a further embodiment of this utility model: the interior of the rotating disk is provided with a limiting groove that matches the fixed block, the two sides of the rotating disk are respectively fixedly connected with locking blocks, and the bottom of the rotating disk is fixedly connected with a mating ring.

[0009] As a further embodiment of this utility model: a base is provided below the rotating disk, and a mating groove is provided above the base, with the mating ring located inside the mating groove and slidably connected thereto.

[0010] As a further embodiment of this utility model: a second limiting groove is provided above the base, and the second limiting groove has the same size as the first limiting groove.

[0011] As a further embodiment of this utility model: mounting plates are fixedly connected to both sides of the base, a sliding rod is provided inside the mounting plate, the sliding rod passes through the mounting plate and is slidably connected thereto, a locking hook is fixedly connected to the top of the sliding rod, the locking hook is adapted to the locking block, a base plate is fixedly connected to the bottom end of the sliding rod, and a spring is fixedly connected between the base plate and the mounting plate, the spring being sleeved on the outside of the sliding rod.

[0012] As a further embodiment of this utility model: a connecting rod is fixedly connected above the force-bearing block, and a pressure plate is fixedly connected above the connecting rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By opening a limiting groove one and a limiting groove two on the rotating disk and the base respectively, and the rotating disk and the base are rotatably connected through a mating ring and a mating groove, after the fixing block is placed inside the limiting groove two through the limiting groove one, the rotating disk is rotated to fix the fixing block. The fixing effect is good and there will be no displacement or shaking during use, which improves the accuracy of the sensor.

[0015] 2. By setting mounting plates, sliding rods, locking hooks, and springs on both sides of the base, the rotating disk can be locked to ensure that the rotating disk will not shift during the operation of the sensor's anti-offset wheel spoke elastomer. This further stabilizes the sensor's anti-offset wheel spoke elastomer, making replacement and maintenance convenient. At the same time, the structure is simple, reliable, and inexpensive.

[0022] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution:

[0024] A sensor anti-eccentric load spoke-type elastomer includes a force-bearing block 1, with several shear beams 2 arranged in a ring around the outer side of the force-bearing block 1. A support block 3 is provided at the end of the shear beam 2 away from the force-bearing block 1. Several fixing blocks 4 are fixedly connected to the outer side of the support block 3. The fixing blocks 4 are evenly distributed in a ring around the outer side of the support block 3. A rotating disk 5 is provided below the fixing blocks 4. The interior of the rotating disk 5 has a limiting groove 6 adapted to the fixing blocks 4. Locking blocks 7 are fixedly connected to both sides of the rotating disk 5. A mating ring 8 is fixedly connected to the bottom of the rotating disk 5. By setting the shear beams 2 arranged in a ring around the force-bearing block 1, the force-bearing block 1 can be made perpendicular to the force-bearing surface when the force-bearing block 1 is under force, thereby improving the detection accuracy. During installation, the fixing blocks 4 are aligned with the limiting groove 6, and then the fixing blocks 4 are placed into the limiting groove 11 through the limiting groove 6. Then, the operator rotates the rotating disk 5 so that the limiting groove 6 is no longer aligned with the fixing blocks 4. The rotating disk 5 presses the fixing blocks 4 down, thus completing the fixing of the fixing blocks 4.

[0025] A base 9 is provided below the rotating disk 5, and a mating groove 10 is provided above the base 9. The mating ring 8 is located inside the mating groove 10 and is slidably connected to it. A second limiting groove 11 is provided above the base 9. The second limiting groove 11 has the same size as the first limiting groove 6. The rotating disk 5 and the base 9 are rotatably connected through the mating ring 8 and the mating groove 10. The second limiting groove 11 restricts the fixing block 4 inside it. The rotating disk 5 fixes the fixing block 4 in place, ensuring that it will not shake or move during use.

[0026] Mounting plates 12 are fixedly connected to both sides of the base 9. A sliding rod 13 is provided inside the mounting plate 12, which passes through the mounting plate 12 and is slidably connected to it. A locking hook 14 is fixedly connected to the top of the sliding rod 13, which is adapted to the locking block 7. A base plate 15 is fixedly connected to the bottom of the sliding rod 13. A spring 16 is fixedly connected between the base plate 15 and the mounting plate 12. The spring 16 is sleeved on the outside of the sliding rod 13. When the rotating disk 5 is rotated, the locking block 7 rotates synchronously with the rotating disk 5 until the locking block 7 is engaged in the locking hook 14, thus completing the fixation of the rotating disk 5. When maintenance or replacement is required, the operator applies an upward force to the two base plates 15, causing the spring 16 to contract. At this time, the sliding rod 13 drives the locking hook 14 to move upward, and the locking hook 14 disengages from the locking block 7. Then, the rotating disk 5 is rotated again to align the limiting groove 6 with the fixing block 4, so that the force block 1, shear beam 2 and support block 3 can be removed for maintenance or replacement.

[0027] A connecting rod 17 is fixedly connected above the force-bearing block 1, and a pressure plate 18 is fixedly connected above the connecting rod 17. During use, the pressure is transmitted from the pressure plate 18 to the force-bearing block 1 through the connecting rod 17.

[0028] The working principle of this utility model is as follows:

[0029] During use, pressure is transmitted from the pressure plate 18 to the force-bearing block 1 through the connecting rod 17. By setting annular shear beams 2 around the force-bearing block 1, the force-bearing block 1 can be perpendicular to the force-bearing surface when under force, improving the detection accuracy. During installation, the fixing block 4 is aligned with the limiting groove 6, and then the fixing block 4 is placed into the limiting groove 11 through the limiting groove 6. Then, the operator rotates the rotating disk 5 so that the limiting groove 6 is no longer aligned with the fixing block 4, and the rotating disk 5 presses the fixing block 4 down, completing the fixing of the fixing block 4. The rotating disk 5 and the base 9 are rotatably connected through the mating ring 8 and the mating groove 10. The limiting groove 11 restricts the fixing block 4 inside, and the rotating disk 5 fixes the fixing block 4, ensuring that it will not shake or shift during use, thus improving the accuracy of the sensor. When the rotating disk 5 is rotated, the locking block 7 rotates synchronously with the rotating disk 5 until the locking block 7 is engaged inside the locking hook 14, thus completing the fixation of the rotating disk 5 and further stabilizing the sensor anti-eccentric load spoke elastomer. This ensures that the rotating disk will not shift during the operation of the sensor anti-eccentric load spoke elastomer. When maintenance or replacement is required, the operator applies an upward force to the two base plates 15, causing the spring 16 to contract. At this time, the sliding rod 13 drives the locking hook 14 to move upward, and the locking hook 14 disengages from the locking block 7. Then, the rotating disk 5 is rotated again to align the limiting groove 6 with the fixing block 4, so that the force-bearing block 1, shear beam 2, and support block 3 can be removed for maintenance or replacement. Replacement and maintenance are convenient.
