Description

Technical Field

[0001] This utility model relates to the field of sensor technology, specifically a multi-angle force measurement sensor. Background Technology

[0002] A force sensor is a device that senses force signals and converts the force value into a corresponding electrical signal. Because it can detect mechanical quantities such as tension, strain, pressure, and weight, it is widely used in power equipment, engineering machinery, and other fields, becoming an indispensable core component. A force sensor is an electronic component that converts force signals into electrical signals for output. A force sensor mainly consists of three parts: 1---Force-sensitive element (i.e., an elastic body, commonly made of aluminum alloy, alloy steel, and stainless steel). 2---Conversion element (most commonly a resistance strain gauge). 3---Circuit section (generally including enameled wire, PCB board, etc.).

[0003] Current force sensors are inconvenient to install stably when performing multi-angle measurements, especially when using force sensors of different sizes. This makes it difficult to adapt and fix them according to their dimensions, which affects the stability and accuracy of the sensor during subsequent measurements.

[0004] To address the aforementioned issues, there is an urgent need to design a multi-angle force sensor. Utility Model Content

[0005] The purpose of this invention is to provide a multi-angle force sensor to solve the problem mentioned in the background art that current force sensors are inconvenient to install stably when performing multi-angle measurements, especially when using force sensors of different sizes, it is not easy to adapt and fix them according to their size, which affects the stability and accuracy of the sensor in subsequent measurements.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-angle force sensor, comprising a sensor body and a base located below the sensor body. The sensor body is disposed above the base, and a mounting groove is provided on the base. An adjusting ring is disposed inside the mounting groove, and a driving ring is fixed to the surface of the adjusting ring. A conical toothed block is disposed on the surface of the driving ring. A vertical plate is fixed to the upper surface of the base, and a driving rod is mounted on the vertical plate. A conical gear is mounted at one end of the driving rod. The conical gear is located above the driving ring and is connected to the conical toothed block. A clamping rod is connected to the outer side of the driving rod, and a top plate is fixed to the surface of the clamping rod. The top plate is clamped to the surface of the sensor body.

[0007] Preferably, the adjusting ring is rotatably connected to the base via a mounting groove.

[0008] Preferably, the conical tooth blocks are evenly distributed on the surface of the drive ring, and the conical gear is meshed with the drive ring through the conical tooth blocks.

[0009] Preferably, the drive rod and the vertical plate are connected by a through-type rotatable connection, and the drive rod and the clamping rod are connected by a threaded connection.

[0010] Preferably, a limiting rod is also fixed to the surface of the clamping rod, and the limiting rod and the vertical plate are connected by a through sliding connection.

[0011] Preferably, the surface of the top plate is provided with a rubber anti-slip pad.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the sensor body is placed in the middle position on the upper surface of the base, and then the adjusting ring is pushed to rotate on the base. At this time, the adjusting ring drives the bevel gear to rotate through the drive ring and the bevel gear block. In turn, the bevel gear drives the drive rod to rotate on the vertical plate. This facilitates the displacement adjustment of the drive rod by pushing the clamping rod through the thread. Therefore, it is convenient for the clamping rod to be clamped and held on the surface of the sensor body by the rubber anti-slip pad, which can be easily adapted to its size to clamp and fix it stably, avoiding affecting the stability of subsequent measurements.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a multi-angle force sensor, including a sensor body 13 and a base 1 located below the sensor body 13. The sensor body 13 is disposed above the base 1. An installation groove 2 is provided on the base 1. An adjustment ring 3 is disposed inside the installation groove 2. A drive ring 4 is fixed on the surface of the adjustment ring 3. A conical tooth block 5 is disposed on the surface of the drive ring 4. A vertical plate 6 is fixed on the upper surface of the base 1. A drive rod 7 is installed on the vertical plate 6. A conical gear 8 is installed at one end of the drive rod 7. The conical gear 8 is located above the drive ring 4 and is connected to the conical tooth block 5. A clamping rod 9 is connected to the outside of the drive rod 7. A top plate 11 is fixed on the surface of the clamping rod 9. The top plate 11 is clamped to the surface of the sensor body 13.

[0020] The adjusting ring 3 is rotatably connected to the base 1 through the mounting groove 2, which can push the adjusting ring 3 to rotate on the base 1 through the mounting groove 2, thereby facilitating the movement of related structures.

[0021] The conical tooth blocks 5 are evenly distributed on the surface of the drive ring 4. The bevel gear 8 is meshed with the drive ring 4 through the conical tooth blocks 5. When the drive ring 4 rotates, the drive ring 4 can drive the bevel gear 8 to rotate synchronously through the conical tooth blocks 5.

[0022] The drive rod 7 is connected to the vertical plate 6 by a through-type rotating connection, and the drive rod 7 is connected to the clamping rod 9 by a threaded connection. The drive rod 7 can rotate on the vertical plate 6, and the rotating drive rod 7 can push the clamping rod 9 to adjust its displacement through the thread.

[0023] The surface of the clamping rod 9 is also fixed with a limiting rod 10. The limiting rod 10 and the vertical plate 6 are connected by a through sliding connection. The limiting rod 10 and the vertical plate 6 cooperate to restrict the movement direction of the clamping rod 9, so that it can only make linear displacement and prevent the clamping rod 9 from rotating synchronously with the drive rod 7.

[0024] The surface of the top plate 11 is provided with a rubber anti-slip pad 12, which can improve the stability of the top plate 11 in clamping the sensor body 13 and prevent slippage.

[0025] Working principle: According to Figures 1-4As shown, the sensor body 13 is first placed in the middle of the upper surface of the base 1. Then, the adjusting ring 3 is pushed to rotate on the base 1 through the mounting groove 2. At this time, the adjusting ring 3 drives the bevel gear 8 to rotate through the drive ring 4 and the bevel gear block 5. The bevel gear 8 then drives the drive rod 7 to rotate on the vertical plate 6. This facilitates the drive rod 7 to push the clamping rod 9 to adjust its displacement through the thread. At this time, the limiting rod 10 cooperates with the vertical plate 6 to restrict the movement direction of the clamping rod 9, so that it can only make linear displacement. This prevents the clamping rod 9 from rotating synchronously with the drive rod 7. The linearly moving clamping rod 9 can drive the top plate 11 to move closer to the sensor body 13. The top plate 11 is clamped to the surface of the sensor body 13 by the rubber anti-slip pad 12, which is convenient to adapt to its size and clamp it stably, so as to avoid affecting the stability of subsequent measurements.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
