Description

Technical Field

[0001] This invention relates to the field of sensor technology, and in particular to a portable sensor capable of detecting and transmitting data. Background Technology

[0002] A sensor is a device with detection capabilities, such as detecting gases or distances. Sensors are characterized by their intelligence and miniaturization. Traditionally, when using a sensor, a data cable is plugged into a connector on the sensor's surface, and the other end of the cable is combined with other auxiliary devices for use. During operation, with the assistance of these devices, the sensor's camera performs infrared detection or partial discharge ultrasonic / ground wave detection to complete the detection task.

[0003] In daily use, it has been found that, for the convenience of using and carrying sensors, the data cable and sensor port are designed to be plugged in, which facilitates sensor connection and makes it easy to quickly unplug the data cable and store the sensor after use. However, relying solely on a plug-in connection results in insufficient stability between the data cable and the sensor, making it prone to loosening and disconnection. This can lead to short circuits during use and affect the sensor's performance. Summary of the Invention

[0004] The purpose of this invention is to provide a portable sensor capable of detecting and transmitting data, thereby solving the problem that the connection between the sensor and the data cable in the prior art is prone to loosening and detachment.

[0005] To achieve the above objectives, the present invention provides a portable sensor capable of detecting and transmitting data, comprising:

[0006] The sensor body has a connector for connecting a data cable.

[0007] A fixing device is arranged at the socket. The fixing device includes a mounting base, an arc plate, and a rotating base. The mounting base is fixedly assembled with the sensor body. At least three sets of arc plates are arranged along the circumference of the socket. The top of each set of arc plates is hinged to the mounting base. When rotating, each set of arc plates has a closed state in which the bottoms are close together and closed along the radial direction of the socket, and an open state in which the bottoms are far apart.

[0008] The rotating seat is rotatably assembled in the mounting base around the insertion center line of the socket. The center of the rotating seat has a central hole for the data cable to pass through. A connecting rope is also connected between the rotating seat and each of the arc plates. When the rotating seat rotates, it is used to make the connecting rope wrap around the outside of the rotating seat to pull the arc plate to a closed state.

[0009] A locking component is movably mounted on the mounting base, the locking component having a locked state in which it is anti-rotated with the rotating base to lock the rotating base and an unlocked state in which it unlocks the rotating base.

[0010] Preferably, the mounting base is provided with a limiting post extending radially along the rotating base, and a stabilizing plate is provided at the end of the limiting post away from the mounting base. The outer side of the rotating base is provided with a sliding groove extending circumferentially therein, and the stabilizing plate is embedded in the sliding groove for circumferential guiding assembly with the sliding groove.

[0011] Preferably, the inner wall surface of the stabilizing plate is curved, the curved surface extends circumferentially along the rotating seat, and the curved surface is guided and engaged with the bottom wall of the sliding groove.

[0012] Preferably, the mounting base is provided with a sliding hole extending radially along the rotating seat, and a slot is formed on the bottom wall of the sliding groove. The locking assembly includes a sliding rod, a first spring, and a locking block. The sliding rod is slidably mounted in the sliding hole along the radial direction of the rotating seat. The locking block is arranged at one end of the sliding rod near the rotating seat. The first spring is press-fitted between the locking block and the mounting base. When the locking assembly is in the locked state, the locking block is embedded in the slot. When the locking assembly is in the unlocked state, the locking block is disengaged from the slot.

[0013] Preferably, a positioning rod extending axially along the sliding hole is further arranged inside the sliding hole, and a positioning groove extending axially along the outer wall of the sliding rod is provided, and the positioning rod is guided and assembled with the positioning groove.

[0014] Preferably, the mounting base is further provided with a reinforcing groove, the reinforcing groove is arranged parallel to and spaced apart from the sliding hole, and the sliding rod is further provided with a reinforcing block. When the locking component is in the locked state, the reinforcing block is inserted into the reinforcing groove.

[0015] Preferably, the outer side of the rotating seat is provided with a stabilizing groove extending circumferentially thereon, and one end of the connecting rope is connected to the stabilizing groove.

[0016] Preferably, a second spring is also connected between the outer wall of the arc-shaped plate and the mounting base, the second spring being used to apply an elastic force to the arc-shaped plate that tends to close.

[0017] Preferably, the mounting base includes an mounting ring and a mounting plate. One end of the mounting plate is connected to the mounting ring, and the other end is fixedly mounted to the sensor body. The mounting ring is coaxially arranged with the rotating base. The top end of the arc-shaped plate is hinged to the bottom end of the mounting ring. The bottom end of the arc-shaped plate is arranged towards the side close to the insertion port. The locking component is arranged on the mounting ring.

[0018] Preferably, the rotating seat includes an operating ring, connecting posts, and a rotating ring. The operating ring and the rotating ring are arranged coaxially. The operating ring and the rotating ring are connected by a plurality of sets of connecting posts. The inner holes of the operating ring and the rotating ring form the central hole. The connecting rope is connected between the rotating ring and the arc-shaped plate. The locking assembly is fitted with the operating ring to prevent rotation and is in a locked state.

[0019] Compared with existing technologies, the portable sensor for detection and data transmission disclosed in this invention has the following advantages: A fixing device is installed at the connector of the sensor body. When the data cable is plugged into the connector, it first passes through the central hole of the rotating base, then the bottom of the arc-shaped plate is pressed. Under pressure, the arc-shaped plate rotates around its top, moving its bottom away to an open state. The data cable passes through the arc-shaped plate and can then be inserted into the connector to connect with the sensor body. When the rotating base rotates, a connecting rope pulls the arc-shaped plate, causing it to rotate around its top to a closed state. After the bottom of the arc-shaped plate closes, it radially clamps the data cable. Simultaneously, the locking component moves to a locked state to engage with the rotating base to prevent rotation, keeping the arc-shaped plate in a closed state and maintaining the clamping force on the data cable to secure it. This makes the connection between the data cable and the connector more stable and secure, less prone to loosening or detachment, and prevents short circuits during use. This improves the sensor's performance and portability, facilitating storage after use. Attached Figure Description

[0028] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0029] A preferred embodiment of the present invention is a portable sensor capable of detecting and transmitting data, such as... Figures 1 to 7 As shown, the portable sensor capable of detecting and transmitting data includes a sensor body 1 and a fixing device 2. The sensor body 1 can be any commonly used sensor. The fixing device 2 is arranged on the sensor body 1 and is used to fix the data cable connected to the sensor body 1 to prevent it from falling off.

[0030] The sensor body 1 has a connector 4 on its surface for connecting to a data cable. In this embodiment, the sensor body 1 is rectangular in shape, and the connector 4 is located on the end face along the length of the sensor body 1. A camera 3 is also fixedly connected to the surface of the sensor body 1, and the camera 3 is located on the end face away from the connector 4. An indicator light 5 is also fixedly connected to the surface of the sensor body 1 to display the working status of the sensor body 1. The structures of the connector 4, camera 3, and indicator light 5, as well as their assembly structure with the sensor body 1, are all existing technologies and will not be described in detail here.

[0031] The fixing device 2 is arranged at the socket 4 of the sensor body 1, directly above the socket 4, to secure the data cable connected to the socket 4 and prevent it from loosening after connection. The fixing device 2 includes a mounting base, an arc plate 204, and a rotating base. The arc plate 204 and the rotating base are both assembled and connected to the mounting base, which is fixedly connected to the sensor body 1 to fix the fixing device 2 at the socket 4.

[0032] At least three sets of arc-shaped plates 204 are arranged circumferentially around the insertion port 4. The three sets of arc-shaped plates 204 are distributed in the shape of petals. The top of each set of arc-shaped plates 204 is hinged to the mounting base, and the tops of the arc-shaped plates 204 in each set fit together to form a closed ring. In this embodiment, there are three sets of arc-shaped plates 204. The top of each set of arc-shaped plates 204 is connected to a rotating block 205. The rotating block 205 has a T-shaped cross-section. The rotating block 205 is rotatably assembled with the mounting base so that the arc-shaped plate 204 is hinged to the mounting base through the rotating block 205. In other embodiments, the number of arc-shaped plates 204 can also be four, five, etc.

[0033] Each set of arc-shaped plates 204 can open and close its bottom when rotating around the rotating block 205. When the bottoms of each set of arc-shaped plates 204 are closed together along the radial direction of the socket 4, the arc-shaped plates 204 are in a closed state, and each set of arc-shaped plates 204 forms a closed hemispherical structure. When the bottoms of each set of arc-shaped plates 204 are far apart from each other, the arc-shaped plates 204 are in an open state, and a channel for data cables to pass through is formed between the centers of the bottoms of each set of arc-shaped plates 204. The data cables can pass through the bottoms of the arc-shaped plates 204 and be plugged into the socket 4.

[0034] The mounting base has a hollow internal structure. The rotating base is mounted inside the mounting base and rotates around the insertion center line of the socket 4. That is, when the rotating base rotates, it rotates around the data cable that is inserted into the socket 4. The center of the rotating base has a central hole, which is coaxial with the insertion center line of the socket 4. The central hole allows the data cable to pass through the rotating base and be inserted into the socket 4.

[0035] A connecting rope 206 is also connected between the outer wall of the rotating seat and the inner wall of each arc plate 204. One end of the connecting rope 206 pulls the rotating seat, and the other end pulls the arc plate 204. When the rotating seat rotates, it winds the connecting rope 206, allowing it to wrap around the outside of the rotating seat, thereby pulling the arc plate 204 to a closed state. When the arc plate 204 is closed, it can radially clamp the data cable, preventing it from slipping back. The connecting rope 206 provides clamping force to the arc plate 204, ensuring a stable connection between the data cable and the connector 4.

[0036] The fixing device 2 also includes a locking component, which is movably mounted on the mounting base. The locking component is used to limit the state of the rotating seat so that after the rotating seat rotates and retracts the connecting rope 206, it is in the limited position and will not rotate back under the pull of the connecting rope 206. During the movement of the locking component on the mounting base, when the locking component is anti-rotationally mounted with the rotating seat, the locking component is in the locked state, and the rotating seat retracts the connecting rope 206 to close the arc plate 204; when the locking component is unlocked from the rotating seat, the locking component is in the unlocked state, and the rotating seat can rotate within the mounting base to either rotate back or retract the connecting rope 206.

[0037] This portable sensor capable of detecting and transmitting data has a fixing device 2 at the socket 4 of the sensor body 1. When the data cable is plugged into the socket 4, it first passes through the central hole of the rotating base, and then the bottom of the arc plate 204 is squeezed. After being pressed, the arc plate 204 rotates around the top to move the bottom away to the open state. The data cable passes through the arc plate 204 and can be inserted into the socket 4 to connect with the sensor body 1. When the rotating base rotates, the connecting rope 206 pulls the arc plate 204, causing the arc plate 204 to rotate around the top to the closed state. After the bottom end of the arc plate 204 is closed, it radially clamps the data cable. At the same time, the locking component moves to the locked state to cooperate with the rotating base to prevent rotation, so that the arc plate 204 remains in the closed state, maintaining the clamping force on the data cable to fix the data cable. This makes the connection between the data cable and the socket 4 more stable and firm, and less likely to loosen or detach. It prevents short circuits in the sensor body 1 during use, improves the performance of the sensor body 1, and further improves the portability of the sensor body 1, making it convenient to store after use.

[0038] Preferably, the mounting base is provided with a limiting post 211 extending radially along the rotating base, and a stabilizing plate 223 is provided at the end of the limiting post 211 away from the mounting base. A sliding groove 210 extending circumferentially is provided on the outer side of the rotating base, and the stabilizing plate 223 is embedded in the sliding groove 210 for circumferential guidance assembly with the sliding groove 210.

[0039] A sliding groove 210 is provided on the rotating seat, and the stabilizing plate 223 of the limiting post 211 is embedded in the sliding groove. When the rotating seat rotates in the rotating assembly, the stabilizing plate 223 can cooperate with the groove wall of the sliding groove 210 to guide the rotation of the rotating seat, so that the rotating seat can only rotate in the circumferential direction. At the same time, the limiting post 211 supports the rotating seat through the sliding groove 210. The stabilizing plate 223 and the limiting post 211 can give the rotating seat a stable initial operating position, so that the rotating seat can be arranged in the assembly without moving its position.

[0040] In this embodiment, there are two sets of limiting posts 211. The two sets of limiting posts 211 are evenly distributed along the circumference of the rotating seat, and the two sets of limiting posts 211 are symmetrically arranged relative to each other. The ends of the two sets of limiting posts 211 that are close to each other are connected to a stabilizing plate 223, so that the rotating seat is subjected to uniform force and rotates stably.

[0041] Preferably, the inner wall surface of the stabilizing plate 223 is curved, and the curved surface extends circumferentially along the rotating seat, and the curved surface is guided and engaged with the bottom wall of the sliding groove 210.

[0042] The inner wall of the stabilizing plate 223 is the side closest to the rotating seat. Since the inner wall is curved, it can be in close contact with the bottom wall of the sliding groove 210. When the rotating seat rotates, the inner wall of the stabilizing plate 223 can always be completely in contact with the bottom wall of the sliding groove 210, so that the stabilizing plate 223 and the bottom wall of the sliding groove 210 are slidably connected, increasing the stability of the rotating seat when it rotates.

[0043] Preferably, the mounting base is provided with a sliding hole 213 extending radially along the rotating base, and a slot 212 is provided on the bottom wall of the sliding groove 210. The locking assembly includes a sliding rod 214, a first spring 216, and a locking block 215. The sliding rod 214 is slidably mounted in the sliding hole 213 along the radial direction of the rotating base. The locking block 215 is arranged at one end of the sliding rod 214 near the rotating base. The first spring 216 is pressed and mounted between the locking block 215 and the mounting base. When the locking assembly is in the locked state, the locking block 215 is embedded in the slot 212. When the locking assembly is in the unlocked state, the locking block 215 is disengaged from the slot 212.

[0044] The locking assembly consists of a slide rod 214, a first spring 216, and a locking block 215. The slide rod 214 is radially guided to the sliding hole 213 on the mounting base. The sliding hole 213 limits the movement direction of the slide rod 214. The relative position of the locking block 215 at the end of the slide rod 214 and the locking groove 212 in the sliding groove 210 changes the assembly relationship between the locking assembly and the rotating base, thereby adjusting the working state of the locking assembly. A first retaining spring is press-fitted between the locking block 215 and the mounting base. The first retaining spring applies an elastic force to the slide rod 214 toward the rotating base, which can drive the slide rod 214 to move toward the rotating base, thereby preventing the locking block 215 from rotating and engaging with the locking groove 212, thus locking the locking assembly in a locked state. The first retaining ring provides power for the movement of the slide bar 214, so that the retaining block 215 can be automatically inserted into the retaining slot 212 to fix the position of the rotating seat, thereby making it easier to reinforce the data cable, further improving the portability during use, and also improving the portability of the sensor body 1.

[0045] When the data cable is not connected to the socket 4, the rotating seat is in its initial state within the assembly base. At this time, the locking block 215 is located within the sliding groove 210 but is offset from the slot 212 in the circumferential direction of the rotating seat. That is, the locking block 215 is disengaged from the slot 212, the locking component is in the unlocked state, and the rotating seat can rotate. When the data cable is connected to the socket 4, the rotating seat rotates within the assembly base, pulling the connecting rope 206 to close the arc plate 204. As the rotating seat rotates, the sliding groove 210 rotates until the slot 212 moves to a position coaxial with the slide rod 214. Under the elastic force of the first spring 216, the slide rod 214 drives the locking block 215 to embed into the slot 212. The locking block 215 and the slot 212 are anti-rotation assembled to prevent the rotating seat from rotating back. At this time, the locking component is in the locked state, and the rotating seat cannot rotate back, maintaining the pulling force on the connecting rope 206.

[0046] In this embodiment, there are two sets of locking components and two sets of sliding holes 213, each corresponding to a locking component. The sliding rods 214 of the two sets of locking components are arranged symmetrically about the rotating seat, and the sliding rods 214 of the two sets of locking components are arranged in a cross shape with the two sets of limiting posts 211, which increases the arrangement space between the locking components and the limiting posts 211. At the same time, the 90-degree space between a set of limiting posts 211 and a set of sliding rods 214 is the rotation stroke of the rotating seat, which makes it easy for the operator to determine the rotation angle and is convenient to use.

[0047] In this embodiment, one end of the principle locking block 215 of the slide bar 214 is also fixedly connected to an operating block 217. The operating block 217 is a circular plate structure, and the arc surface of the operating block is provided with several evenly distributed anti-slip protrusions. By setting the operating block 217, when the data cable is pulled out of the socket 4 of the sensor body 1, the slide bar 214 can be pulled more conveniently, and it is not easy to slip out of the hand during the pulling process. This ensures that the data cable can be pulled out stably and quickly, and further improves the convenience of using the sensor body 1. It is also more convenient to store it after use, and further improves the functionality of the fixing device 2.

[0048] Preferably, a positioning rod 219 extending axially along the sliding hole 213 is also arranged inside the sliding hole 213, and a positioning groove 218 extending axially along the outer wall of the sliding rod 214 is provided, and the positioning rod 219 and the positioning groove 218 are guided and assembled.

[0049] The guide assembly between the positioning rod 219 and the positioning groove 218 can limit the sliding direction of the slide rod 214 in the sliding hole 213, increase the limiting effect of the slide rod 214 during reciprocating sliding, thereby making the sliding more stable and less prone to shaking. This allows the locking block 215 to be accurately and stably locked into the locking groove 212, preventing misalignment and improving the effectiveness of the fixing device 2. It also allows the data cable to be stably reinforced during use.

[0050] In this embodiment, there are two sets of positioning rods 219, which are symmetrically arranged at intervals along the circumference of the sliding hole 213. There are also two sets of positioning grooves 218 on the outer wall of the slide rod 214. The two sets of positioning grooves 218 are assembled one-to-one with the two sets of positioning rods 219. The two sets of positioning rods 219 and the two sets of positioning grooves 218 limit the movement of the slide rod 214, further increasing the stability of the movement of the slide rod 214.

[0051] Preferably, the mounting base is also provided with a reinforcing groove 222, which is arranged parallel to and spaced apart from the sliding hole 213. The sliding rod 214 is also provided with a reinforcing block 221, which is inserted into the reinforcing groove 222 when the locking component is in the locked state.

[0052] A reinforcing block 221 is provided on the slide rod 214. When the slide rod 214 slides towards the rotating seat under the elastic force of the first spring 216, the slide rod 214 drives the reinforcing block 221 to slide synchronously. The reinforcing block 221 can be inserted into the reinforcing groove 222 and engaged with the inner wall of the reinforcing groove 222. Through the engagement of the reinforcing block 221 with the reinforcing groove 222, the position of the slide rod 214 is more stable and firm, thereby further improving the stability of the rotating seat and preventing the rotating seat from rotating. At the same time, it also allows the arc plate 204 to better contact and squeeze the arc surface of the data cable, making the installation and insertion of the data cable more stable and further improving the performance of the fixing device 2.

[0053] In this embodiment, the reinforcing block 221 has an "L"-shaped cross-section. One end of the reinforcing block 221 is perpendicularly connected to the slide rod 214, and the other end is parallel to the slide rod 214, so that it can be inserted into the reinforcing groove 222 as the slide rod 214 moves. There are two sets of reinforcing blocks 221 and two sets of reinforcing grooves 222. The two sets of reinforcing blocks 221 are arranged symmetrically along the slide rod 214, and the two sets of reinforcing grooves 222 are located on both sides of the sliding hole 213 and are arranged symmetrically about the sliding hole 213. The cooperation of the two sets of reinforcing blocks 221 and reinforcing grooves 222 further increases the stability of the slide rod 214.

[0054] Preferably, a stabilizing groove 220 extending circumferentially is provided on the outer side of the rotating seat, and one end of the connecting rope 206 is connected to the stabilizing groove 220.

[0055] A stabilizing groove 220 is provided on the rotating seat, and the connecting rope 206 is connected in the stabilizing groove 220. With the setting of the stabilizing groove 220, when the rotating seat rotates and drives the connecting rope 206 to wrap around the outer wall of the rotating seat, the connecting rope 206 can be wrapped in the stabilizing groove 220, which makes it difficult for the connecting rope 206 to slip and loosen. This stably drives each arc plate 204 to move closer to each other, and fixes the arc surface of the data cable in contact, ensuring the normal use of the fixing device 2 and preventing abnormalities. This further improves the practical effect of the fixing device 2.

[0056] Preferably, a second spring 203 is also connected between the outer wall of the arc plate 204 and the mounting base. The second spring 203 is used to apply an elastic force to the arc plate 204 to tend to a closed state.

[0057] The second spring 203 can keep the arc plates 204 in a closed state with their bottoms in contact when the data cable is not inserted. At the same time, together with the connecting rope 206, it can increase the force that brings the arc plates 204 closer together, increase the friction between the arc plates 204 and the data cable, and ensure the stability of the data cable.

[0058] Preferably, the mounting base includes an mounting ring 201 and a mounting plate 202. One end of the mounting plate 202 is connected to the mounting ring 201, and the other end is fixedly mounted to the sensor body 1. The mounting ring 201 is arranged coaxially with the rotating base. The top end of the arc plate 204 is hinged to the bottom end of the mounting ring 201. The bottom end of the arc plate 204 is arranged towards the side close to the socket 4. The locking component is arranged on the mounting ring 201.

[0059] The assembly plate 202 has an L-shaped structure, forming the legs of the assembly base and supporting and fixing it to the sensor body 1, thus supporting the assembly ring 201. The assembly ring 201 is the main structure of the assembly base, serving to arrange the locking components and connect the arc plate 204. In this embodiment, there are three sets of assembly plates 202, which are evenly distributed along the circumference of the assembly ring 201. Three sets of second springs 203 are connected between the inner wall surface of the assembly plate 202 and the outer wall surface of the arc plate 204.

[0060] Preferably, the rotating seat includes an operating ring 209, a connecting post 208, and a rotating ring 207. The operating ring 209 and the rotating ring 207 are arranged coaxially and connected by a number of connecting posts 208. The inner holes of the operating ring 209 and the rotating ring 207 form a central hole. A connecting rope 206 is connected between the rotating ring 207 and the arc plate 204. The locking assembly is fitted with the operating ring 209 to prevent rotation and is in a locked state.

[0061] The rotating seat is formed by an operating ring 209, a connecting column 208, and a rotating ring 207. The operating ring 209 and the rotating ring 207 are arranged coaxially. The operating ring 209 is provided with a sliding groove 210, which is connected to the assembly ring 201 and the locking component. The rotating ring 207 is provided with a stabilizing groove 220 and is connected to the connecting rope 206. This allows the rotating seat to be connected to the assembly seat and the arc plate 204 respectively, and also provides space for the assembly of the sliding groove 210 and the connecting rope 206, making it convenient for the operator to rotate the operating ring 209 to drive the rotating ring 207 to rotate.

[0062] In this embodiment, there are two connecting posts 208. The two connecting posts 208 are evenly spaced along the circumference of the operating ring 209 and the rotating ring 207. The operating ring 209 and the rotating ring 207 are connected as a whole by the connecting posts 208. When the operator rotates the operating ring 209, the rotating ring 207 is driven to rotate synchronously through the connecting posts 208.

[0063] The working process of this invention is as follows:

[0064] When the sensor body 1 is in use, the data cable is plugged into the socket 4 on the surface of the sensor body 1. First, the data cable is passed through the hole of the assembly ring 201, and then through the hole of the rotating ring 207, until the plug of the data cable is pressed against the position where the three arc plates 204 are in contact with each other.

[0065] Continue inserting downwards with force. This will push the three arc-shaped plates 204 apart. Because the cross-section of the rotating block 205 is "T" shaped, the arc-shaped plates 204 will rotate around the rotating block 205 as the axis of rotation when they are pushed apart. The rotating block 205 will rotate on the inner wall of the assembly ring 201, so that the data cable passes through the position where the three arc-shaped plates 204 are close to each other until the data cable is inserted into the socket 4. At this time, the arc-shaped plates 204 are in the open state.

[0066] Then rotate the operating ring 209, causing the sliding groove 210 of the operating ring 209 to rotate on the inner wall of the stabilizing plate 223 on the two limiting posts 211. This causes the rotating ring 207 to rotate through the connecting post 208, causing the connecting rope 206 to wind around in the stabilizing groove 220 on the outer wall of the rotating ring 207. This causes the arc-shaped plates 204 to move closer to each other. At the same time, the connecting rope 206 pulls the arc-shaped plates 204 to further contact and compress the arc surface of the data cable until the slot 212 on the operating ring 209 rotates to the position of the corresponding slide rod 214.

[0067] The slide bar 214 will slide along the inner wall of the slide hole 213 under the elastic force of the first spring 216 until the locking block 215 fixedly connected to the slide bar 214 is locked into the locking groove 212, thereby fixing the position of the operating ring 209. The two fixedly connected reinforcing blocks 221 on the slide bar 214 will be locked into the two reinforcing grooves 222 on the assembly ring 201. At this time, the data cable is fixed and the locking component is in the locked state.

[0068] When unplugging the data cable, the same operation as above can be performed. During the use of the sensor body 1, the data cable can be stably connected to the connector 4 of the sensor body 1. The connection and installation are more stable and secure, and it is not easy to loosen or detach, which would cause short circuit abnormalities during use. This further improves the use effect of the sensor body 1 and also further improves the portability of the sensor body 1, making it convenient to store after use.

[0069] In summary, this invention provides a portable sensor capable of detecting and transmitting data. A fixing device is installed at the connector of the sensor body. When the data cable is inserted into the connector, it first passes through the central hole of the rotating base, then the bottom of the arc-shaped plate is pressed. Under pressure, the arc-shaped plate rotates around its top, moving its bottom away to an open state. The data cable passes through the arc-shaped plate and is then inserted into the connector to connect with the sensor body. When the rotating base rotates, a connecting rope pulls the arc-shaped plate, causing it to rotate around its top to a closed state. After the bottom of the arc-shaped plate closes, it radially clamps the data cable. Simultaneously, a locking component moves to a locked state to engage with the rotating base to prevent rotation, keeping the arc-shaped plate in a closed state and maintaining the clamping force on the data cable to secure it. This makes the connection between the data cable and the connector more stable and secure, less prone to loosening or detachment, and prevents short circuits during use. This improves the sensor's performance and portability, facilitating storage after use.

[0070] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
