Description

Technical Field

[0001] The invention belongs to the technical field of pressure detection, in particular to a micro pressure detection device with temperature compensation. Background Art

[0002] A miniature pressure detection device with temperature compensation is a miniature sensor that can measure pressure and automatically correct the influence of temperature. It uses a built-in temperature compensation mechanism to ensure that it can still provide accurate pressure readings in different temperature environments. Existing miniature pressure detection with temperature compensation is mostly achieved through miniature pressure testers, which usually use piezoresistive or capacitive sensors to detect pressure changes, monitor the ambient temperature in real time through temperature sensors, and use algorithms or hardware circuits to correct pressure readings to eliminate the influence of temperature on the measurement results. With the continuous development of miniature pressure detection technology, miniature pressure detection devices are increasingly used in industrial, medical, automotive and other fields.

[0003] Most of the existing micro pressure testers adopt a handheld design. Although it is easy to carry, during the actual detection process, the operator needs to hold the device for a long time to operate, especially in a small space or complex environment. It is easy for the device to fall or collide due to inconvenient operation, causing damage to the device. In addition, the handheld design is not flexible enough in scenarios that require continuous monitoring or fixed installation, which limits its application scope. The user experience and ease of use are poor. The shell material and protective performance of the device are weak, and it is difficult to adapt to the high-intensity use requirements in complex industrial environments. At the same time, the volume and weight distribution of the equipment are unreasonable, and long-term handheld operation can easily cause operator fatigue; on the other hand, the existing micro pressure detection device usually needs to be connected to the object to be tested through a plug-in cable to realize the transmission of the pressure signal. However, the existing device lacks an effective cable management design, which makes the cables easy to tangle and get confused during use, which not only affects the operating efficiency, but also may cause the interface to loosen or be damaged due to cable pulling. The messy placement of cables also increases the difficulty of equipment storage and transportation, reducing the user experience.

[0004] Therefore, a micro pressure detection device with temperature compensation is proposed to solve the problems raised by the background technology. Summary of the invention

[0005] In order to solve the problems raised in the above background technology, the present invention provides a micro pressure detection device with temperature compensation.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a miniature pressure detection device with temperature compensation, comprising a detection instrument body, a plurality of jacks provided on the detection instrument body, cables plugged into the jacks, and a detection head installed at one end of the plurality of cables away from the detection instrument body, and further comprising:

[0007] A bottom plate, the bottom plate is used to support the detector body, a vertical plate is fixedly provided on the top of the bottom plate, a storage box is provided on the top sliding sleeve of the vertical plate, and the storage box is used to store the detector body;

[0008] The mounting frame is fixedly arranged on the top of the detector body, a mounting plate is fixedly arranged on the top of the mounting frame, a fixing component is arranged on the mounting plate, and a winding component is arranged on the mounting frame.

[0009] Preferably, the mounting plate is U-shaped, and the detector body is placed close to the mounting frame and the mounting plate.

[0010] Preferably, the fixing assembly includes clamping plates symmetrically arranged on both sides of the detector body, a movable plate fixedly arranged on the two clamping plates, two guide rods slidably arranged on the movable plate, and a driving component arranged on the mounting plate for driving the two clamping plates to move closer to or away from each other.

[0011] Preferably, the clamp is L-shaped and made of elastic rubber material. The side of the clamp away from the movable plate is clamped with the detector body. The two guide rods are symmetrically arranged on the mounting plate and fixedly connected to the mounting plate. The movable plate on one side moves toward each other along the guide rods.

[0012] Preferably, the driving component includes a connecting groove opened on one side of the mounting plate, a cam located at the inner center of the connecting groove, a driving rod fixedly arranged at the center of the cam and rotatably connected to the inner wall of the connecting groove, and a driving motor fixedly arranged at one end of the driving rod.

[0013] Preferably, the cam abuts against one side of the movable plate, one end of the driving rod passes through the mounting plate, and the driving motor is fixedly connected to a side of the mounting plate away from the detector body.

[0014] Preferably, a telescopic spring is sleeved on the outer walls of the two guide rods, and two ends of the telescopic spring are respectively fixedly connected to the two movable plates.

[0015] Preferably, the winding assembly includes two winding rollers arranged on the side of the mounting plate away from the detector body, two sets of fixed plates rotatably arranged on the top and bottom of the two winding rollers, and a control motor fixed on the fixed plates for driving the winding rollers to rotate.

[0016] Preferably, the fixing plate is fixedly connected to the mounting plate, and a cable is wound around the winding roller.

[0017] Preferably, a plurality of guide rings arranged in a linear array are fixedly provided on both symmetrical sides of the mounting frame, and the plurality of guide rings are all made of rubber material, and the cables pass through the guide rings.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention facilitates the rapid fixation and storage of the detector body by arranging the cooperation of structures such as the mounting frame, the mounting plate, the fixing assembly and the winding assembly. To achieve the portability and ease of use of the detector body, the detector body can be placed on the bottom plate and close to one side of the mounting frame. The rapid storage is achieved through the cooperation of the fixing assembly, the winding assembly and the guide ring. The detector body is placed against the mounting plate, and the driving component is used to drive one side of the moving plate to move along the guide rod so that the clamping plate is brought closer to the center to clamp and fix the detector body. The winding assembly is then used to quickly wind up the cable, and finally the storage box is closed to complete the storage. This solves the problem that the existing detection device is inconvenient to carry and place when in use, and the cables are relatively messy, which can easily lead to damage to the detector body.

[0020] The present invention facilitates the rapid fixation of the detector body by arranging the coordination of structures such as the clamping plate, the guide rod and the driving component. The driving component drives the driving rod and the cam to rotate through the driving motor to realize the rapid driving of the clamping plate. When the protruding part of the cam approaches the movable plate, the movable plate is squeezed to push the detector body to the other side, so that the clamping plate clamps the detector body. At this time, the telescopic spring is compressed. When the flat part of the cam approaches the movable plate, the telescopic spring is reset, pushing the movable plate to reset, and the clamping plates move away from each other, making it easy to remove the detector body.

[0021] The present invention facilitates the rapid winding of cables by arranging the coordination of structures such as a winding roller, a fixing plate and a guide ring. The cable can be quickly wound up through the coordination of the winding assembly and the guide ring. When in use, the cable is passed through the guide ring and wound around the winding roller. The control motor is started to drive the winding roller to rotate, and the cable is wound up until there is no excess cable hanging to the ground. When it is needed, the control motor is reversed to loosen the cable to complete the operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 7 As shown, the present invention provides a miniature pressure detection device with temperature compensation, comprising a detection instrument body 1, a plurality of jacks provided on the detection instrument body 1, cables 11 plugged into the jacks, and a detection head 12 installed at one end of the plurality of cables 11 away from the detection instrument body 1, and further comprising:

[0032] A bottom plate 2, the bottom plate 2 is used to support the detector body 1, a vertical plate 21 is fixedly provided on the top of the bottom plate 2, a storage box 22 is slidably sleeved on the top of the vertical plate 21, and the storage box 22 is used to store the detector body 1;

[0033] The mounting frame 3 is fixedly arranged on the top of the detector body 1, a mounting plate 31 is fixedly arranged on the top of the mounting frame 3, a fixing component 32 is arranged on the mounting plate 31, a winding component 33 is arranged on the mounting frame 3, the mounting plate 31 is U-shaped, and the detector body 1 is placed close to the mounting frame 3 and the mounting plate 31.

[0034] The above scheme is adopted: when in use, in order to realize the convenient carrying and use of the detector body 1, it can be placed on the base plate 2 so that it is close to one side of the mounting frame 3, and the fixing component 32, the winding component 33 and the guide ring 34 are used to realize quick storage. Specifically, by leaning the detector body 1 against the mounting plate 31, the driving component 324 is used to drive one side of the movable plate 322 to move along the guide rod 323, so that the clamping plate 321 on one side moves toward the center and pushes the detector body 1 close to the other side clamping plate 321, thereby realizing the quick clamping and fixing of the detector body 1. After fixing, the cable 11 is quickly wound up by the winding component 33, and after winding up, the storage box 22 is covered on the vertical plate 21, thereby realizing the storage effect.

[0035] like Figure 6 As shown, the fixing assembly 32 includes clamping plates 321 symmetrically arranged on both sides of the detector body 1, a moving plate 322 fixedly arranged on the two clamping plates 321, two guide rods 323 slidably arranged on the moving plate 322, and a driving component 324 arranged on the mounting plate 31 for driving the two clamping plates 321 to move closer to or away from each other. The clamping plates 321 are L-shaped and made of rubber material with elasticity. The side of the clamping plate 321 away from the moving plate 322 is clamped with the detector body 1, and the two guide rods 323 are symmetrically arranged on the mounting plate 31 and fixedly connected to the mounting plate 31. The moving plate 322 on one side moves toward each other along the guide rods 323.

[0036] The driving component 324 includes a connecting groove 3241 opened on one side of the mounting plate 31, a cam 3242 located at the inner center of the connecting groove 3241, a driving rod 3243 fixedly arranged at the center of the cam 3242 and rotatably connected to the inner wall of the connecting groove 3241, and a driving motor 3244 fixedly arranged at one end of the driving rod 3243. The cam 3242 abuts against one side of the movable plate 322, one end of the driving rod 3243 passes through the mounting plate 31, and the driving motor 3244 is fixedly connected to the side of the mounting plate 31 away from the detector body 1. The outer walls of the two guide rods 323 are both provided with telescopic springs 325, and the two ends of the telescopic springs 325 are respectively fixedly connected to the two movable plates 322.

[0037] Adopting the above scheme: the device realizes the rapid drive of the clamping plate 321 through the driving component 324, so that the detector body 1 can be clamped efficiently and stably. The specific working process is as follows: when the detector body 1 needs to be clamped, the driving motor 3244 is started, and the driving motor 3244 drives the cam 3242 to rotate synchronously through the driving rod 3243. As the cam 3242 rotates, when the raised part of the cam 3242 approaches the moving plate 322 on one side, the cam 3242 will apply an inward extrusion force to the moving plate 322. Under the action of the extrusion force, the moving plate 322 moves toward the center along the guide rod 323, and at the same time drives the clamping plate 321 connected thereto to move synchronously toward the center. At this time, the detector body 1 moves toward the moving plate 322 on the other side under the push of the clamping plate 321, and finally the clamping plates 321 on both sides firmly clamp the detector body 1 in the center position to ensure that it will not be displaced or shaken during operation. During this process, the telescopic spring 325 is in a compressed state due to the squeezing of the moving plate 322, providing elastic potential energy for subsequent resetting. When the detection task is completed or the detector body 1 needs to be removed, the driving motor 3244 continues to drive the cam 3242 to rotate. When the flat side of the cam 3242 approaches the moving plate 322, the moving plate 322 loses the squeezing force of the cam 3242. At this time, the elastic potential energy of the telescopic spring 325 is released, pushing the moving plate 322 to reset outward along the guide rod 323. The resetting of the moving plate 322 drives the clamping plate 321 connected thereto to move outward synchronously, so that the clamping plates 321 on both sides are away from each other, thereby releasing the clamping state of the detector body 1. At this time, the detector body 1 can be easily removed for subsequent storage or replacement.

[0038] like Figure 7 As shown, the winding assembly 33 includes two winding rollers 331 arranged on the side of the mounting plate 31 away from the detector body 1, two sets of fixed plates 332 rotatably arranged on the top and bottom of the two winding rollers 331, and a control motor 333 fixedly arranged on the fixed plate 332 for driving the winding rollers 331 to rotate, the fixed plate 332 is fixedly connected to the mounting plate 31, the cable 11 is wound around the winding roller 331, and a plurality of guide rings 34 arranged in a linear array are fixedly arranged on both symmetrical sides of the mounting frame 3, and the plurality of guide rings 34 are made of rubber, and the cable 11 passes through the guide rings 34.

[0039] The above solution is adopted: through the coordinated cooperation of the winding component 33 and the guide ring 34, the cable 11 can be wound quickly and efficiently, effectively solving the problem of messy and difficult to manage cables in traditional detection equipment. The specific operation process is as follows: when using the device, in order to prevent the cable 11 from getting tangled, disordered or drooping during operation, first pass the cable 11 through the guide ring 34. The design of the guide ring 34 can accurately guide the direction of the cable 11 to ensure that it remains neat and orderly during the winding process, avoiding the influence of operating efficiency or damage to the equipment due to the disorder of the cables, and then the cable 11 is wound on the winding roller 331, and the winding roller 331 is driven to rotate by starting the control motor 333;

[0040] The power transmission of the control motor 333 makes the winding roller 331 rotate smoothly, thereby driving the cable 11 wound thereon to be quickly wound. During the winding process, the guide ring 34 continuously guides the direction of the cable 11 to ensure that it is evenly and tightly wound on the winding roller 331 to avoid the phenomenon of cable overlap or loosening. When the cable 11 is wound until there is no extra connection line hanging on the ground, the control motor 333 stops rotating. At this time, the cable 11 is neatly stored, and the device as a whole presents a compact and neat state, which is convenient for carrying and transportation. When the device needs to be used for detection, the operator can drive the winding roller 331 to rotate in the opposite direction by controlling the motor 333, so as to gradually loosen the cable 11. The reverse rotation process of the control motor 333 is stable and controllable, and the release length of the cable 11 can be flexibly adjusted according to the actual detection requirements, ensuring that the cable 11 will neither drag on the ground due to being too long nor affect the operation due to being too short during the detection process. The loosening process of the cable 11 remains smooth under the guidance of the guide ring 34, avoiding the situation that the cable 11 is knotted or entangled during the release process.

[0041] The working principle and use process of the present invention: When using the device, first place the detector body 1 steadily on the bottom plate 2, then start the drive motor 3244, and the drive motor 3244 drives the cam 3242 to rotate synchronously through the drive rod 3243. When the raised part of the cam 3242 is close to the moving plate 322 on one side, the cam 3242 will apply a thrust to the moving plate 322 to push it to the other side. In this process, the two moving plates 322 will synchronously drive the clamping plate 321 to move closer to the detector body 1, so as to achieve a fast and stable clamping of the detector body 1, ensuring that it will not be displaced or shaken during operation. After the detector body 1 is fixed, the cable 11 connected to the detector body 1 is passed through the guide ring 34, and the cable 11 is quickly reeled using the reel 331. The design of the guide ring 34 can effectively guide the direction of the cable 11 to avoid it from being entangled or disordered during the reeling process. Subsequently, the storage box 22 is covered on the vertical plate 21 to complete the storage of the entire device. This storage method not only makes the device compact, but also easy to carry and transport. It is particularly suitable for scenes where the detection equipment needs to be frequently moved. When the device is carried to the place of use, it is only necessary to remove the storage box 22 and drive the winding roller 331 to reverse by controlling the motor 333 to relax the cable 11. The relaxation process of the cable 11 is stable and controllable, and the length of the cable 11 can be flexibly adjusted according to the actual detection needs. Subsequently, the operator can connect the detection head 12 to the object to be tested, and use the detector body 1 to perform rapid and accurate pressure detection on the target object. Through the above design, the device not only realizes the rapid fixation of the detector body 1 and the efficient storage of the cable 11, but also significantly improves the portability and ease of operation of the device. Whether it is fixed use or mobile detection, the device can meet the needs of users, while effectively avoiding the problems of easy damage to traditional handheld devices and chaotic cable management, providing users with a more efficient and reliable detection experience.
