Description

Technical Field

[0001] The utility model relates to the technical field of rotary pressure sensors, in particular to a novel rotary pressure sensor. Background Art

[0002] A pressure sensor is a device that can sense external pressure and convert it into an electrical signal. It senses the pressure exerted by gas, liquid or solid, and converts this physical quantity into an electrical signal for subsequent control or monitoring system processing. A rotary pressure sensor is a type of sensor that can measure pressure in a rotating or rotational environment. It is suitable for scenarios that require pressure monitoring in dynamic or rotating operations.

[0003] However, during use, the existing rotary pressure sensor has no limit on the rotation angle, and the sensor can rotate 360° or more. Due to the lack of effective restrictions on the rotation angle, when the sensor is repeatedly rotated more than 360°, the internally connected cables, signal lines or cores are easily entangled and twisted. As the number of rotations increases, this entanglement and twisting will gradually cause the cable to break or be damaged, thereby causing signal transmission interruption and ultimately leading to sensor failure. This phenomenon not only affects the normal operation of the equipment, but also greatly shortens the service life of the sensor. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a new type of rotary pressure sensor, which aims to improve the lack of effective restriction on the rotation angle in the existing technology. When the sensor is repeatedly rotated more than 360 degrees, the internally connected cables, signal lines or cores are easily entangled and twisted. As the number of rotations increases, this entanglement and twisting will gradually lead to the problem of cable breakage or damage.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A novel rotary pressure sensor includes a clutch male seat, the upper portion of which is rotatably connected to a clutch female seat, a control sensor mounted on the upper portion of the clutch female seat, a rotating mechanism disposed within both the clutch male seat and the clutch female seat, and an air intake mounting mechanism disposed below the clutch male seat;

[0007] The rotating mechanism comprises a convex block which is fixedly connected to the inside of the clutch female seat, and a clamping block is fixedly connected to the upper part of the clutch male seat.

[0008] Furthermore, the air intake mounting mechanism includes an air intake joint, which is mounted on the lower part of the clutch male seat, and the air intake joint is externally threaded with a nut.

[0009] Furthermore, a display screen is installed on the upper portion of the control sensor, and the control sensor and the display screen are electrically connected.

[0010] Furthermore, a mounting shell is fixedly connected to the rear side of the exterior of the clutch male seat, and an aviation plug is installed inside the mounting shell.

[0011] Furthermore, an annular groove is provided on the upper portion of the clutch male seat, and the protrusion is slidably connected to the inside of the annular groove.

[0012] Furthermore, a core is installed inside the air inlet joint.

[0013] The utility model has the following beneficial effects:

[0014] In the present invention, when the control sensor needs to be rotated, the clutch female seat at the bottom is first rotated to drive the internal fixed protrusion to rotate in the annular groove on the upper part of the clutch male seat. When the protrusion rotates to the locking block, the sensor stops rotating and reaches an arc of 350 degrees. When resetting, it can be rotated in the opposite direction. This design ensures that the rotation of the control sensor is limited to an arc of 350 degrees, effectively preventing the core from twisting and breaking, thereby extending the service life of the sensor.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1-Figure 5 , the utility model provides an embodiment: a novel rotary pressure sensor, including a clutch male seat 1, the upper part of the clutch male seat 1 is rotatably connected to the clutch female seat 2, the clutch male seat 1 is provided to facilitate the installation of the clutch female seat 2, a control sensor 3 is installed on the upper part of the clutch female seat 2, the clutch female seat 2 is provided to facilitate the installation of the control sensor 3, the clutch male seat 1 and the clutch female seat 2 are both provided with a rotating mechanism, the rotation of the sensor 3 is conveniently controlled by providing the rotating mechanism, the lower part of the clutch male seat 1 is provided with an air intake mounting mechanism, the air intake mounting mechanism includes an air intake connector 4, the air intake connector 4 is used to connect to an external gas or liquid pressure source, the air intake connector 4 is installed at the lower part of the clutch male seat 1, the air intake connector 4 is externally threadedly connected to a nut 10, the air intake connector 4 is conveniently fixed by providing the nut 10, a core 8 is installed inside the air intake connector 4, and the core 8 is responsible for sensing the pressure of the gas or liquid entering through the air intake connector 4;

[0024] The rotating mechanism includes a protrusion 5, which is fixedly connected to the inside of the clutch female seat 2. A block 6 is fixedly connected to the upper part of the clutch male seat 1. An annular groove 7 is provided on the upper part of the clutch male seat 1. The protrusion 5 is slidably connected to the inside of the annular groove 7. The annular groove 7 is provided to facilitate the movement of the protrusion 5. The outer rear side of the clutch male seat 1 is fixedly connected to a mounting shell 9. By providing the mounting shell 9, the aviation plug 12 can be effectively protected from the influence of the external environment, and dust, moisture, etc. can be prevented from entering, thereby ensuring its normal operation. An aviation plug 12 is installed inside the mounting shell 9, and the aviation plug 12 is responsible for the electrical connection between the devices. A display screen 11 is installed on the upper part of the control sensor 3. The control sensor 3 and the display screen 11 are electrically connected. The control sensor 3 is responsible for collecting physical quantities such as pressure, temperature, and position, and transmitting these data to the display screen 11 through an electrical connection. Through the display screen 11, the user can directly observe the feedback of the sensor without having to read the data through other complex equipment, thereby improving the intuitiveness and efficiency of the operation.

[0025] Specifically, when the control sensor 3 needs to be rotated, the clutch base 2 fixed at the bottom of the control sensor 3 is first rotated manually or automatically. When the clutch base 2 starts to rotate, the protrusion 5 fixed inside it slides together in the upper annular groove 7 of the clutch male base 1. When the clutch base 2 rotates, the protrusion 5 moves along the set trajectory in the annular groove 7, driving the entire control sensor 3 to rotate. When the clutch base 2 and the protrusion 5 rotate to the extreme position set by the block 6, the protrusion 5 will come into contact with the block 6 and cannot move forward. This means that the rotation action reaches the maximum allowable angle. At this time, the control sensor 3 has rotated exactly 350°. The design at this time effectively prevents the sensor from further rotating through mechanical limiting. Rotation avoids excessive rotation after exceeding 350°. Such angle control helps prevent the core 8 inside the control sensor 3 from being entangled, twisted or stretched due to excessive rotation, thereby avoiding the risk of the core 8 breaking or failing. When the sensor needs to be reset, the operator rotates the clutch base 2 in the opposite direction, and the protrusion 5 will slide in the opposite direction along the annular groove 7 until it returns to its initial position. The entire reset process is also limited, which ensures that the clutch base 2 and the control sensor 3 can accurately return to the origin, thereby ensuring normal rotation when used again, and realizing that when the control sensor 3 is rotated, the control sensor 3 can be rotated 350°, which can avoid the core 8 from twisting and breaking, thereby extending the service life of the sensor.

[0026] Working principle: When the control sensor 3 needs to be rotated, first, rotate the clutch base 2 fixed at the bottom of the control sensor 3. When the clutch base 2 rotates, it carries the internally fixed protrusion 5 to rotate inside the annular groove 7 opened on the upper part of the clutch male base 1. When the clutch base 2 rotates with the protrusion 5 to the outside of the block 6, it can stop rotating. At this time, the control sensor 3 has rotated 350°. When it needs to be reset, just rotate it in the opposite direction. This realizes that when the control sensor 3 is rotated, the control sensor 3 can be rotated 350°, which can avoid the distortion and breakage of the core 8 and extend the service life of the sensor.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
