Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to an assembled speed sensor. Background Technology

[0002] Currently, in various equipment and systems involving motor operation, accurate measurement of rotational speed is crucial for stable operation, performance optimization, and fault diagnosis. As a key component for acquiring rotational speed data, the ease of installation and flexibility of angle adjustment of the speed sensor directly impact the overall operating efficiency and maintenance costs of the equipment.

[0003] Currently, the installation of traditional speed sensors typically requires a variety of complex tools and involves cumbersome steps. Some sensors require precise alignment of mounting holes and tightening with bolts and nuts, which is extremely difficult to operate in confined installation spaces. This not only consumes a lot of time but also easily leads to sensor loosening or damage due to improper installation, affecting measurement accuracy. Moreover, after installation, existing speed sensors are often difficult to adjust the angle flexibly according to actual needs. Once traditional sensors are installed, their angle is basically fixed. If the angle needs to be adjusted, it must be disassembled and reinstalled, which is a complicated, time-consuming, and labor-intensive process. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an assembled speed sensor.

[0005] This utility model is achieved using the following technical solution: an assembled speed sensor, including a motor, a speed sensor is provided on one side of the motor, and a fixing component is provided on both sides of the speed sensor to quickly fix the speed sensor to the motor. The fixing component is provided with an adjusting component to adjust the fixed size of the fixing component. A fixing ring is fixedly sleeved on the speed sensor. The fixing component includes a rotating column fixedly installed on one side of the fixing ring. A first connecting plate is rotatably sleeved on the rotating column. A first clamping plate with an "L" shape is fixedly installed on one side of the bottom end of the first connecting plate. A insertion groove is opened at the bottom end of the first clamping plate. A second clamping plate with an "L" shape is provided at the bottom end of the first clamping plate. The top end of the second clamping plate extends into the interior of the insertion groove.

[0006] The above technical solution enables the fixing component to quickly fix the speed sensor to the motor. Compared with the traditional installation method, the operation is simpler and faster, saving installation time. At the same time, the setting of the first and second clamps allows the fixing component to adapt to motor mounting parts of different shapes and sizes, improving the versatility of the sensor.

[0007] As a further improvement to the above solution, the second clamping plate has multiple through-hole fixing holes on one side, and the first clamping plate has a fixing plate on one side, with one side of the fixing plate penetrating the first clamping plate and located inside the adjacent fixing holes.

[0008] With the above technical solution, after the second clamping plate slides and adjusts its position in the insertion slot of the first clamping plate, the position of the second clamping plate can be fixed by inserting the fixing plate into different fixing ports, thereby further adjusting the clamping range of the fixing component so that it can adapt to more motors of different sizes.

[0009] As a further improvement to the above solution, rubber plates arranged in an "L" shape are fixedly installed at the right angles of the first clamping plate and the second clamping plate.

[0010] Through the above technical solution, the rubber plate has good elasticity and friction. On the one hand, it can increase the friction between the clamp and the motor, making the fixation more stable and preventing the speed sensor from shifting during motor operation. On the other hand, the rubber plate can also play a buffering role, avoiding damage to the motor surface caused by the clamp. In addition, the rubber plate can be compressed, allowing the first clamp and the second clamp to achieve a slight over-contraction.

[0011] As a further improvement to the above solution, the adjustment assembly includes a bidirectional threaded rod disposed between two first clamping plates, with the two ends of the two bidirectional threaded rods passing through adjacent first connecting plates and first clamping plates in sequence, and rotating blocks fixedly installed at both ends of the bidirectional threaded rods.

[0012] By using the above technical solution, rotating the rotating block drives the bidirectional threaded rod to rotate. Since the threads at both ends of the bidirectional threaded rod are in opposite directions, during the rotation, the two first clamping plates will move towards or away from each other along the bidirectional threaded rod, thereby adjusting the distance between the two first clamping plates, further adapting to the installation requirements of motors of different sizes, and also facilitating the adjustment of the tightness of the fixation according to the actual situation.

[0013] As a further improvement to the above solution, each of the two rotating columns has a plurality of first fixing slots arranged in a ring array at one end, and each of the two rotating blocks has a plurality of second fixing slots arranged in a ring array on its cylindrical surface. Each of the two first clamping plates has an L-shaped second connecting plate at its top. The top of the second connecting plate is ring-shaped, and the inner ring diameter of the second connecting plate is larger than the diameter of the rotating column. Both ends of the two second connecting plates are fixedly installed with plug-in plates, and one side of each plug-in plate extends into the interior of the adjacent first fixing slot or second fixing slot.

[0014] With the above technical solution, when it is necessary to adjust the angle of the speed sensor, first slide the second connecting plate to pull the plug-in plate out of the current first or second fixed slot, then rotate the rotating block to drive the bidirectional threaded rod to rotate, thereby adjusting the position of the two first clamping plates, and then rotate the rotating column to adjust the angle of the speed sensor; after the adjustment is completed, slide the second connecting plate again to insert the plug-in plate into the appropriate first or second fixed slot to fix the angle of the speed sensor; this design allows the speed sensor to be easily adjusted after installation to meet different measurement needs.

[0015] As a further improvement to the above solution, rubber sleeves are slidably fitted on both of the two second connecting plates, and fixing blocks are fixedly fitted on both rubber sleeves. Both fixing blocks are fixedly installed to the top of the adjacent first clamping plate.

[0016] Through the above technical solution, the rubber sleeve can increase the damping of the second connecting plate when sliding, making the sliding process more stable and avoiding excessive angle adjustment due to improper operation when adjusting the angle.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention, by setting up a fixing component and utilizing the cooperation of the first and second clamping plates, allows for the quick fixation of the speed sensor onto the motor without the need for complex tools, reducing installation difficulty and saving installation time. With the help of the adjustment component and the synergistic effect of the first fixing slot, the second fixing slot, the second connecting plate, and the plug-in plate, the angle of the speed sensor can be easily adjusted without disassembling the sensor to adapt to different measurement environments and needs, thus improving the flexibility of the sensor in use.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Please combine Figures 1-3 The assembly-type speed sensor 2 of this embodiment includes a motor 1. The speed sensor 2 is provided on one side of the motor 1. Both sides of the speed sensor 2 are provided with fixing components that can quickly fix the speed sensor 2 to the motor 1. The fixing components are provided with adjusting components that can adjust the size of the fixing components.

[0026] A fixing ring 5 is fixedly sleeved on the speed sensor 2. The fixing assembly includes a rotating column 301 fixedly installed on one side of the fixing ring 5. A first connecting plate 302 is rotatably sleeved on the rotating column 301. A first clamping plate 303 with an "L" shape is fixedly installed on one side of the bottom end of the first connecting plate 302. A insertion groove is opened at the bottom end of the first clamping plate 303. A second clamping plate 304 with an "L" shape is provided at the bottom end of the first clamping plate 303. The top end of the second clamping plate 304 extends into the interior of the insertion groove.

[0027] The fixing assembly can quickly fix the speed sensor 2 to the motor 1. Compared with the traditional installation method, the operation is simpler and faster, saving installation time. At the same time, the setting of the first clamping plate 303 and the second clamping plate 304 allows the fixing assembly to adapt to the installation parts of the motor 1 with different shapes and sizes, improving the versatility of the sensor.

[0028] The second clamping plate 304 has multiple through-hole fixing ports on one side, and the first clamping plate 303 has a fixing plate 6 on one side. One side of the fixing plate 6 passes through the first clamping plate 303 and is located inside the adjacent fixing ports. After the second clamping plate 304 slides and adjusts its position in the insertion slot of the first clamping plate 303, the fixing plate 6 can be inserted into different fixing ports to fix the position of the second clamping plate 304, thereby further adjusting the clamping range of the fixing component so that it can adapt to more motors 1 of different sizes. The right angle of the first clamping plate 303 and the right angle of the second clamping plate 304 are both fixedly installed with rubber plates 7 arranged in an "L" shape. The rubber plates 7 have good elasticity and friction. On the one hand, they can increase the friction between the clamping plate and the motor 1, making the fixation more stable and preventing the speed sensor 2 from being displaced during the operation of the motor 1. On the other hand, the rubber plates 7 can also play a buffering role to avoid the clamping plate from damaging the surface of the motor 1. In addition, the rubber plates 7 can be compressed, allowing the first clamping plate 303 and the second clamping plate 304 to achieve a slightly excessive contraction.

[0029] The adjustment assembly includes a bidirectional threaded rod 401 disposed between two first clamping plates 303. The two ends of the two bidirectional threaded rods 401 pass through adjacent first connecting plates 302 and first clamping plates 303 in sequence. Rotating blocks 402 are fixedly installed at both ends of the bidirectional threaded rods 401. Rotating the rotating blocks 402 causes the bidirectional threaded rods 401 to rotate. Since the thread directions at both ends of the bidirectional threaded rods 401 are opposite, during rotation, the two first clamping plates 303 will move towards or away from each other along the bidirectional threaded rods 401, thereby adjusting the distance between the two first clamping plates 303, further adapting to the installation requirements of motors 1 of different sizes, and also facilitating the adjustment of the tightness of the fixation according to the actual situation.

[0030] Each of the two rotating columns 301 has multiple first fixing slots arranged in a circular array at one end. Each of the two rotating blocks 402 has multiple second fixing slots arranged in a circular array on its cylindrical surface. Each of the two first clamping plates 303 has an "L"-shaped second connecting plate 8 at its top. The top of the second connecting plate 8 is circular, and the inner diameter of the second connecting plate 8 is larger than the diameter of the rotating column 301. Each end of the two second connecting plates 8 is fixedly fitted with a plug-in plate 9. One side of each plug-in plate 9 extends into the interior of the adjacent first or second fixing slot. When the angle of the speed sensor 2 needs to be adjusted, first slide the second connecting plate 8 to pull the plug-in plate 9 out of its current first or second fixing slot. Then rotate the rotating block 402 to drive the bidirectional threaded rod 40. 1. Rotate to adjust the position of the two first clamping plates 303, and then rotate the rotating column 301 to adjust the angle of the speed sensor 2. After adjustment, slide the second connecting plate 8 to insert the plug plate 9 into the appropriate first or second fixing slot to fix the angle of the speed sensor 2. This design allows the speed sensor 2 to be easily adjusted after installation to meet different measurement needs. Rubber sleeves 10 are slidably fitted on both second connecting plates 8, and fixing blocks 11 are fixedly fitted on both rubber sleeves 10. Both fixing blocks 11 are fixedly installed to the top of the adjacent first clamping plate 303. The rubber sleeves 10 can increase the damping when the second connecting plates 8 slide, making the sliding process more stable and avoiding excessive angle adjustment due to improper operation.

[0031] The implementation principle of the assembled speed sensor 2 in this application embodiment is as follows: During installation, first slide the second connecting plate 8 inside the rubber sleeve 10 to pull the plug plate 9 out of the current first fixed groove and second fixed groove. In this way, the fixing effect of the rotating block 402 will be released. Then, according to the size of the motor 1 installation part, rotate the rotating block 402 to make the bidirectional threaded rod 401 rotate, which drives the two first clamping plates 303 to move towards or away from each other. Adjust the distance between the two first clamping plates 303 to clamp the motor 1.

[0032] Then, slide the second clamping plate 304 into the insertion slot of the first clamping plate 303, adjust it to a suitable position, and then fix it by inserting the fixing plate 6 into the corresponding fixing hole on the second clamping plate 304.

[0033] Next, the clamping part of the fixing component is clamped onto the mounting part of the motor 1. At this time, the rubber plate 7 at the right angle of the first clamping plate 303 and the second clamping plate 304 will be in close contact with the surface of the motor 1, increasing the friction and playing a protective role. The rubber plate 7 can be compressed, allowing the first clamping plate 303 and the second clamping plate 304 to achieve a slightly excessive contraction and clamp tighter.

[0034] Then rotate the rotating column 301 to adjust the angle of the speed sensor 2.

[0035] After adjusting to the appropriate angle, slide the second connecting plate 8 again to insert the plug plate 9 into the appropriate first and second fixing slots, fixing the rotating block 402 and the rotating column 301, thus fixing the angle of the speed sensor 2.

[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
