Description

Technical Field

[0001] This utility model belongs to the field of torque sensor technology, and in particular relates to a portable and fast torque sensor. Background Technology

[0002] In modern industrial production and equipment manufacturing, the requirements for the assembly accuracy and operational stability of mechanical components are becoming increasingly stringent. Torque, as a key parameter for measuring the force and operating state of mechanical components, is crucial for accurate detection. Portable and fast torque sensors, with their flexible and convenient detection characteristics, are widely used in various production, maintenance, and quality inspection scenarios.

[0003] However, existing fast torque sensors are not portable and it is difficult to adjust the handle spacing according to the user's hand size. Users cannot easily maintain a proper handle spacing when holding the sensor, which increases hand fatigue caused by carrying the sensor for a long time. Utility Model Content

[0004] The purpose of this invention is to provide a portable and fast torque sensor. By setting an adjustment mechanism, it solves the problems of existing fast torque sensors being inconvenient to carry, difficult to adjust the handle spacing according to the user's hand size, and making it difficult for the user to maintain a suitable handle spacing when holding the sensor, thus increasing hand fatigue caused by carrying the sensor for a long time.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a portable and fast torque sensor, including a small high-rigidity torque sensor, which is provided with an adjustment mechanism and a snap-fit ​​mechanism.

[0007] The adjustment mechanism includes two fixed blocks fixedly connected to the top of the small high-rigidity torque sensor. T-shaped grooves are provided on the side of the two fixed blocks that are close to each other. Two T-shaped sliders are slidably connected to the inner walls of the two T-shaped grooves. Two rectangular plates are fixedly connected to the side of the T-shaped sliders that are close to each other. A protective shell is provided on the top of the small high-rigidity torque sensor.

[0008] Furthermore, the top of the small high-rigidity torque sensor is fixedly connected to several grooved limiting blocks, and the inner walls of the grooved limiting blocks are slidably connected to two handles.

[0009] Furthermore, the two handles are respectively fixedly connected to two rectangular plates on their sides that are close to each other, and two limiting blocks are fixedly connected to the top of the small high-rigidity torque sensor. The front side of the limiting block located on the front side is fixedly connected to the protective shell.

[0010] Furthermore, a bidirectional threaded rod is rotatably connected between the two limiting blocks, the front side of the bidirectional threaded rod passes through the limiting block located on the front side, the bidirectional threaded rod passes through the two rectangular plates, the bidirectional threaded rod is threadedly connected to the two rectangular plates, and a knob is fixedly connected to the front side of the protective shell.

[0011] Furthermore, the inner wall of the protective shell is provided with several limiting grooves, the outer wall of the knob is fixedly connected to a second fixing block, the side of the second fixing block away from the knob is fixedly connected to a telescopic rod, the outer wall of the telescopic rod is fitted with a spring, the bottom of the spring is fixedly connected to the second fixing block, the top of the telescopic rod is fixedly connected to the second limiting block, the second limiting block is adapted to several limiting grooves, and the top of the spring is fixedly connected to the second limiting block.

[0012] This utility model has the following beneficial effects:

[0013] 1. By setting an adjustment mechanism, when adjusting the position of the two handles, turn the knob. The knob drives the two rectangular plates to move away from each other under the limit of several T-shaped sliders and two T-shaped grooves through the double-threaded rod. Thus, the two rectangular plates drive the two handles to move away from each other under the limit of several grooved limit blocks until the distance between the two handles is suitable for the size of the user's palm. Stop turning the knob to complete the adjustment. At this time, squeezing the two handles will move the small high-rigidity torque sensor, allowing the user to adjust the handle spacing according to their own palm size, so that the user can maintain a suitable handle spacing when holding the sensor, thereby reducing hand fatigue caused by carrying the sensor for a long time.

[0014] 2. By incorporating a locking mechanism, when the knob is rotated, the knob, via its fixed block two, drives the telescopic rod to rotate around the knob. This, in turn, causes the telescopic rod to rotate its limiting block two. When the limiting block two is pressed against its corresponding limiting groove, it moves towards the knob, thus compressing the spring and telescopic rod, causing them to retract. This continues until the limiting block two slides into the next limiting groove. The spring then rebounds, causing the limiting block two to lock into the next limiting groove, thereby locking the knob and securing the adjustment mechanism. This prevents changes in the adjusted handle spacing due to external force or other factors during use, ensuring stability and comfort for the user.

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.

[0025] Please see Figure 1-5As shown, this utility model is a portable and fast torque sensor, including a small high-rigidity torque sensor 1. The small high-rigidity torque sensor 1 is equipped with an adjustment mechanism 2 and a snap-fit ​​mechanism 3. The adjustment mechanism 2 includes two fixing blocks 211 fixedly connected to the top of the small high-rigidity torque sensor 1. T-shaped grooves 212 are formed on the sides of the two fixing blocks 211 that are close to each other. Two T-shaped sliders 213 are slidably connected to the inner walls of the two T-shaped grooves 212. Two rectangular plates 214 are fixedly connected to the sides of the T-shaped sliders 213 that are close to each other. Several grooved limiting blocks 215 are fixedly connected to the top of the small high-rigidity torque sensor 1. Two handles 216 are slidably connected to the inner walls of the grooved limiting blocks 215. The sides of the two handles 216 that are close to each other are respectively connected to… Two rectangular plates 214 are fixedly connected. The top of the small high-rigidity torque sensor 1 is fixedly connected to two limiting blocks 217. The front side of the limiting block 217 located on the front side is fixedly connected to the protective shell 311. A bidirectional threaded rod 218 is rotatably connected between the two limiting blocks 217. The front side of the bidirectional threaded rod 218 passes through the limiting block 217 located on the front side and passes through the two rectangular plates 214. The bidirectional threaded rod 218 is threadedly connected to the two rectangular plates 214. A knob 219 is fixedly connected to the front side of the protective shell 311. By setting the adjustment mechanism 2, the user can adjust the distance of the handle 216 according to the size of their own palm, so that the user can maintain a suitable distance of the handle 216 when holding it, thereby reducing hand fatigue caused by carrying the sensor for a long time.

[0026] The top of the small high-rigidity torque sensor 1 is provided with a protective shell 311. The inner wall of the protective shell 311 is provided with several limiting grooves 312. The outer wall of the knob 219 is fixedly connected to a fixing block 313. The side of the fixing block 313 away from the knob 219 is fixedly connected to a telescopic rod 314. The outer wall of the telescopic rod 314 is fitted with a spring 315. The bottom of the spring 315 is fixedly connected to the fixing block 313. The top of the telescopic rod 314 is fixedly connected to a limiting block 316. The limiting block 316 is adapted to several limiting grooves 312. The top of the spring 315 is fixedly connected to the limiting block 316. By setting a buckle mechanism 3, the distance of the adjusted handle 216 can be prevented from changing due to external force or other factors during use, thereby ensuring the stability and comfort of the user's grip.

[0027] A specific application of this embodiment is as follows: In use, first adjust the position of the two handles 216, rotate the knob 219. The knob 219 drives the two rectangular plates 214 to move away from each other under the limitation of several T-shaped sliders 213 and two T-shaped grooves 212 through the bidirectional threaded rod 218. Thus, the two rectangular plates 214 drive the two handles 216 to move away from each other under the limitation of several grooved limit blocks 215, until the distance between the two handles 216 is suitable for the size of the user's palm. Stop rotating the knob 219 to complete the adjustment. At this time, squeezing the two handles 216 can move the small high-rigidity torque sensor 1. The small high-rigidity torque sensor 1 is the small high-rigidity torque sensor RH-1105. Its working principle is as follows: The small high-rigidity torque sensor RH-1105 works based on strain gauge electrical measurement technology. Its elastic shaft generates elastic deformation and strain under the action of torque. According to Hooke's law, strain is proportional to stress and thus related to torque. The strain gauges on the surface of the elastic shaft convert strain into a change in resistance. When connected to form a Wheatstone bridge, the change in resistance breaks the bridge balance, outputting a weak electrical signal proportional to the strain. This electrical signal is amplified, filtered, and then transmitted to the sensor circuit, where it is converted into a torque value and output in analog and digital signal formats for easy connection and data transmission with other devices. When the knob 219 is rotated, the knob 219 drives the telescopic rod 314 to rotate around the knob 219 via the fixed block 313 on it. This causes the telescopic rod 314 to drive the limit block 316 on it to rotate. After being squeezed by the corresponding limit groove 312, the limit block 316 moves towards the knob 219, thereby squeezing the spring 315 and the telescopic rod 314 and causing them to contract until the limit block 316 slides into the next limit groove 312. The spring 315 rebounds, causing the limit block 316 to lock into the next limit groove 312, thus locking the knob 219 and locking the adjustment mechanism 2.
