Description

Technical Field

[0001] This utility model relates to the field of air shaft technology, and in particular to an air shaft air pressure real-time detection device. Background Technology

[0002] An air shaft is a special type of shaft device used for winding and unwinding. It mainly consists of a shaft body, an air bladder (or air cavity), and key strips (or protrusions). The shaft body is the main part of the air shaft and is usually a hollow structure. It contains an inflatable air bladder or air cavity. Key strips are generally distributed on the surface of the shaft body. When the air shaft is inflated, these key strips will protrude outward as the air bladder expands.

[0003] Existing technologies, such as the utility model with publication number CN216638528U, disclose a real-time air pressure detection device for an air shaft, including a support base and a shaft body. A sleeve is fixedly installed on the lower part of the support base, a tensioning port is opened on the side of the shaft body, an arc-shaped plate is attached to the side of the shaft body, an installation hole is opened on the rear side of the arc-shaped plate, a spring is fixedly installed inside the installation hole, a pressure plate is fixedly installed on one end of the spring, and a pressure sensor is attached to the rear side of the pressure plate. This real-time air pressure detection device for an air shaft features an arc-shaped plate attached to the side of the shaft, located at the side of the tensioning port. This allows the internal device to compress the arc-shaped plate. As the arc-shaped plate moves to the side, the spring contracts, applying pressure to the rear pressure plate. Since a pressure sensor is attached to the rear of the pressure plate, the pressure is applied to the sensor, which detects the pressure. This achieves real-time air pressure detection, solving the problem of not being able to detect air pressure and thus not knowing the internal air pressure of the air shaft in real time.

[0004] In daily work, it was found that the above-mentioned real-time air pressure detection device for air shafts has poor overall flexibility when in use. It is difficult to move around flexibly and accurately monitor the air pressure status of different air shafts, which greatly limits its scope of use and application efficiency, resulting in inconvenience in overall use. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies in terms of poor flexibility by proposing a real-time air pressure detection device for an air shaft.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a real-time air pressure detection device for an air shaft, comprising an air shaft body and a detection mechanism. The surface of the air shaft body is provided with multiple ejector components. The detection mechanism is disposed on one side of the air shaft body and includes a collar. The collar is located on one side of the air shaft body, and its surface is provided with a clamping assembly, which clamps the air shaft body. An adjusting sleeve is fixedly connected to the surface of the collar, and a threaded sleeve is threadedly connected to the inner wall of the adjusting sleeve. A pressure sensor is fixedly connected to the inner wall of the sleeve, and a sliding column is slidably connected to the inner wall of the threaded sleeve. An auxiliary block is fixedly connected to one end of the pressure sensor, and a spring is fixedly connected to the side of the auxiliary block corresponding to the sliding column. Through the above components, the collar can be clamped on the air shaft by the clamping assembly. Then, the threaded sleeve is rotated in the adjusting sleeve, and the threaded sleeve can drive the sliding column to contact the ejector. When the ejector is ejected, the sliding column slides in the threaded sleeve, and then the spring is stressed. The squeezing force is transmitted to the auxiliary block and the pressure sensor, thus realizing real-time air pressure detection.

[0007] Preferably, a contact block is fixedly connected to one end of the sliding column. Through the above-mentioned components, the contact area with the ejector can be increased by the contact block, thereby improving the detection effect.

[0008] Preferably, the surface of the threaded sleeve is fixedly connected with four protrusions. Through the above-mentioned components, the threaded sleeve can be rotated in the adjusting sleeve by the protrusions, thereby improving the overall ease of use.

[0009] Preferably, the clamping assembly includes multiple hollow sleeves fixed to the surface of the collar. A slide rod is slidably connected to the inner wall of the hollow sleeve, and a clamping plate is fixedly connected to one end of the slide rod. A screw is rotatably connected to the inner wall of the hollow sleeve, and the screw is threadedly connected to the inner wall of the slide rod. Through the above components, when clamping, the screw can be rotated, and the screw drives the slide rod and the clamping plate to move in the hollow sleeve, so that the multiple clamping plates are clamped on the surface of the air shaft, thereby completing the clamping operation.

[0010] Preferably, a bevel gear one is rotatably connected to the surface of the collar, and a bevel gear two is fixedly connected to one end of the screw. The bevel gear one and the bevel gear two are meshed together. Through the above components, the bevel gear one can be rotated, and the bevel gear one can drive multiple sets of bevel gear two to rotate, while controlling the screw to rotate, thereby improving the overall ease of use.

[0011] Preferably, the clamping plate is arranged in an arc shape.

[0012] Preferably, a plurality of gaskets are fixedly connected to the surface of the clamping plate, and the plurality of gaskets are arranged at equal intervals. Through the above-mentioned components, the clamping plate and the gaskets can increase the friction with the air shaft, thereby improving the anti-slip effect.

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

[0014] 1. In this utility model, by setting up a detection mechanism, the whole assembly can be assembled on air shafts of different sizes through the clamping component, and the sliding column can be adjusted by the threaded sleeve and the adjusting sleeve. When the ejector is ejected, it can push the contact block and the sliding column to slide in the threaded sleeve. The spring is stressed, and the squeezing force is transmitted to the auxiliary block and the pressure sensor to realize real-time detection. It can flexibly detect the air pressure of air shafts of different sizes in real time, thereby improving the overall flexibility.

[0015] 2. In this utility model, by setting up a clamping mechanism, multiple bevel gears and screws are driven by bevel gear one to rotate, so that multiple sets of sliding rods drive the clamping plates to move simultaneously and clamp on the air expansion shaft, thereby improving the overall ease of use.

[0023] Please see Figures 1-5This utility model provides a technical solution: a real-time air pressure detection device for an air shaft, including an air shaft body 1 and a detection mechanism 3. The surface of the air shaft body 1 is provided with a plurality of ejector parts 2, and the detection mechanism 3 is located on one side of the air shaft body 1.

[0024] Specifically, the detection mechanism 3 includes a collar 31, which is located on one side of the air shaft 1. A clamping assembly 32 is provided on the surface of the collar 31, and the collar 31 is clamped on the air shaft 1 by the clamping assembly 32. An adjusting sleeve 33 is fixedly connected to the surface of the collar 31. A threaded sleeve 35 is threadedly connected to the inner wall of the adjusting sleeve 33. A pressure sensor 34 is fixedly connected to the inner wall of the threaded sleeve 35. A sliding column 37 is slidably connected to the inner wall of the threaded sleeve 35. An auxiliary block 310 is fixedly connected to one end of the pressure sensor 34. A spring 39 is fixedly connected to the side of the auxiliary block 310 corresponding to the sliding column 37.

[0025] In this embodiment: the collar 31 can be clamped on the air shaft 1 by the clamping assembly 32, and then the threaded sleeve 35 can be rotated in the adjusting sleeve 33. The threaded sleeve 35 can drive the sliding column 37 to contact the ejector 2. When the ejector 2 is ejected, the sliding column 37 slides in the threaded sleeve 35, and then the spring 39 is stressed. The squeezing force is transmitted to the auxiliary block 310 and the pressure sensor 34, so that the air pressure can be detected in real time.

[0026] Specifically, a contact block 38 is fixedly connected to one end of the sliding column 37, which can increase the contact area with the ejector 2 and improve the detection effect.

[0027] Specifically, the surface of the threaded sleeve 35 is fixedly connected with four protrusions 36. The protrusions 36 can drive the threaded sleeve 35 to rotate in the adjusting sleeve 33, thereby improving the overall ease of use.

[0028] Specifically, the clamping assembly 32 includes a plurality of hollow sleeves 321 fixed on the surface of the collar 31. A slide rod 322 is slidably connected to the inner wall of the hollow sleeve 321. A clamping plate 323 is fixedly connected to one end of the slide rod 322. A screw 325 is rotatably connected to the inner wall of the hollow sleeve 321. The screw 325 is threadedly connected to the inner wall of the slide rod 322.

[0029] In this embodiment: When clamping, the screw 325 can be rotated, and the screw 325 drives the slide bar 322 and the clamping plate 323 to move in the hollow sleeve 321, so that multiple clamping plates 323 are clamped on the surface of the air shaft 1, thus completing the clamping operation.

[0030] Specifically, a bevel gear 326 is rotatably connected to the surface of the collar 31, and a bevel gear 327 is fixedly connected to one end of the screw 325. The bevel gear 326 and the bevel gear 327 are meshed together.

[0031] In this embodiment: the first bevel gear 326 can be rotated, which can drive multiple sets of second bevel gears 327 to rotate, while controlling the screw 325 to rotate, thereby improving the overall ease of use.

[0032] Specifically, the clamp 323 is designed in an arc shape.

[0033] Specifically, multiple gaskets 324 are fixedly connected to the surface of the clamping plate 323, and the multiple gaskets 324 are arranged at equal intervals.

[0034] In this embodiment, the clamping plate 323, together with the gasket 324, can increase the friction with the air shaft 1, thereby improving the anti-slip effect.

[0035] Working principle: During testing, the collar 31 is first fitted onto the surface of the air shaft 1. Then, the first bevel gear 326 is rotated, which drives multiple sets of second bevel gears 327 and the screw 325 to rotate simultaneously. The screw 325 drives the sliding rod 322 and the clamping plate 323 in the hollow sleeve 321 to move. The multiple sets of arc-shaped clamping plates 323, together with the washers 324, can clamp onto the surface of the air shaft 1, thereby fixing the collar 31. Subsequently, the threaded sleeve is driven by the protrusion 36. The threaded sleeve 35 is rotated in the adjusting sleeve 33. When the threaded sleeve 35 is adjusted, it can drive the sliding column 37 and the contact block 38 to move. When the contact block 38 is in contact with the ejector 2, the rotation of the threaded sleeve 35 can be stopped. Then, when the air shaft 1 is inflated, the ejector 2 will be ejected accordingly. When the ejector 2 is ejected, it can push the contact block 38 and the sliding column 37 to slide in the threaded sleeve 35. Then the spring 39 is stressed, and the squeezing force is transmitted to the auxiliary block 310 and the pressure sensor 34, so that the air pressure can be detected in real time.
