Description

Technical Field

[0001] The present invention relates to the technical field of pressure sensors, in particular to a pressure port module for a pressure sensor. Background Art

[0002] A pressure sensor is a device or apparatus that can sense pressure signals and convert them into usable electrical signals according to certain rules. It is usually composed of a pressure sensitive element and a signal processing unit. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors. Pressure sensors are widely used in many industrial automatic control environments such as water conservancy and hydropower, railway transportation, intelligent buildings, aerospace, etc., and are the most commonly used sensors in industrial practice.

[0003] The pressure port module of the pressure sensor refers to the key component that connects the pressure sensor to an external device or system. It is responsible for converting the pressure signal sensed by the sensor into an electrical signal and transmitting it to the subsequent processing device through a specific interface. This module usually has the characteristics of high precision and high reliability, which can ensure the accurate transmission and processing of the pressure signal. At the same time, the pressure port module also has a variety of communication protocols and interface methods to meet the connection requirements of different devices and systems. In practical applications, the pressure port module of the pressure sensor plays a vital role and is one of the key technologies to achieve pressure measurement and control.

[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] Example 1: This example is intended to help solve the problem that if the top of the module encounters a collision, the port module may be ejected from the base, thereby causing data transmission to be disconnected. Please refer to Figures 1 to 8 A pressure port module for a pressure sensor includes a sensor body 1, the sensor body 1 includes a base 11, a port block 12 is installed in the base 11, an anti-foolproof groove 13 is opened in the base 11, an anti-foolproof plug-in block 14 is plugged into the anti-foolproof groove 13, a locking device 2 is provided in the base 11, and the bottom of the port block 12 is fixedly connected with the anti-foolproof plug-in block 14.

[0032] The locking device 2 includes a locking plug-in slot 21 provided on a side wall of the foolproof plug-in block 14 . A locking plug-in plate 24 is plugged into the locking plug-in slot 21 . The locking plug-in plate 24 is disposed in the base 11 .

[0033] The locking plug-in plate 24 is slidably connected in the locking slide groove 22, and the locking slide groove 22 is opened in the base 11. The bottom of the locking plug-in plate 24 is fixedly connected with a locking limit plate 25, and the locking limit plate 25 is slidably connected in the locking limit groove 23, and the locking limit groove 23 is opened in the base 11. One side of the locking limit plate 25 is fixedly connected with a locking spring 26, and the other side of the locking spring 26 is arranged in the locking limit groove 23. The other end of the locking plug-in plate 24 is fixedly connected with a locking wedge block 27.

[0034] The design of the foolproof groove 13 and the foolproof plug-in block 14 in the sensor body 1 can ensure that the connection between the port block 12 and the base 11 will not have an incorrect connection at the interface. The locking plug-in plate 24 in the base 11 is plugged into the locking plug-in groove 21 in the foolproof plug-in block 14, so as to ensure a fixed connection between the two, thereby ensuring the stability of the port block 12 and the base 11 after the connection. The design of the locking limit groove 23 and the locking limit plate 25 limits the sliding distance of the locking plug-in plate 24, avoids the locking plug-in plate 24 from falling off, and ensures the stability of the connection. The design of the locking spring 26 enables the locking plug-in plate 24 to quickly contact the restriction on the port block 12 when the connection needs to be disconnected, thereby ensuring that the port block 12 can be disconnected from the base 11 normally. The design of the locking wedge block 27 facilitates the driving of the rotary drive device 3.

[0035] The sliding of the locking plug plate 24 is driven by the rotation driving device 3, which includes a truncation groove 31 opened in the base 11, which divides the base 11 into upper and lower ends. A rotating plate 32 is installed in the truncation groove 31, and a resistance column 37 is fixedly connected to the top of the rotating plate 32. The top of the resistance column 37 resists the locking plug plate 24.

[0036] The upper and lower sides of the rotating plate 32 are fixedly connected with connecting rings 34 , which are rotatably connected in the connecting groove 33 . The connecting ring 34 connects the upper and lower halves of the base 11 , and the connecting groove 33 is provided in the base 11 .

[0037] A driving groove 35 is provided in the base 11 , and a resisting column 37 is slidably connected in the driving groove 35 . A spiral slider 38 is fixedly connected to the side wall of the resisting column 37 . The spiral slider 38 is slidably connected in the spiral groove 36 , and the spiral groove 36 is provided in the rotating plate 32 .

[0038] A pressure rotation groove 39 is opened in the base 11, and a pressure rotation rod 310 is inserted into the pressure rotation groove 39. A pressure torsion spring 311 is set on the outer wall of the pressure rotation rod 310. The pressure torsion spring 311 is set in the gap between the pressure rotation rod 310 and the pressure rotation groove 39. The pressure rotation rod 310 is fixedly connected to the bottom of the rotating plate 32.

[0039] The rotary drive device 3 is designed to drive the locking plug plate 24 to be inserted into the locking plug slot 21 to ensure a stable connection between the port block 12 and the base 11 .

[0040] Due to the opening of the truncation groove 31, the base 11 is divided into two halves, and the two bases 11 can be connected by a connecting ring 34 fixedly connected to both sides of the truncation groove 31. The connecting ring 34 is designed to be T-shaped, which can effectively avoid the possibility of up and down sliding between the two bases 11.

[0041] The design of the pressure torsion spring 311 ensures that when the port block 12 is installed, the locking plug plate 24 has sufficient force to be inserted into the locking plug slot 21 and ensures the stability of the connection. When installing the port block 12, the rotating plate 32 is rotated first, at which time the pressure torsion spring 311 is in a compressed state, and the locking plug plate 24 is located inside the locking slide slot 22. Then the port block 12 is inserted into the base 11. At this time, the pressure torsion spring 311 is released, and the design of the spiral groove 36 and the spiral slider 38 drives the abutment column 37 to slide upward. The top of the abutment column 37 is driven to abut the locking wedge 27, and the locking plug plate 24 is driven to insert into the locking plug slot 21. The design of the pressure torsion spring 311 can effectively ensure that the abutment column 37 is in an upwardly protruding state, and the elastic design of the pressure torsion spring 311 can effectively alleviate the risk of the locking plug plate 24 being detached due to accidental collision. In this way, compared with the press-type installation method in the prior art, this method greatly improves the stability of the connection between the base 11 and the port block 12.

[0042] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 8 An electrical connection device 4 is provided at the bottom of the fool-proof plug-in block 14, and the electrical connection device 4 includes an electrical connection groove 41 opened in the base 11, and an electrical connection block 42 is inserted in the electrical connection groove 41. A connecting spring 44 is fixedly connected to the bottom of the electrical connection block 42, and the other end of the connecting spring 44 is fixedly connected in the electrical connection groove 41.

[0043] The bottom of the electrical connection block 42 is fixedly connected to a connecting rod 43, which is slidably connected in a connecting slot 45. The connecting slot 45 is provided in the base 11. The bottom of the connecting rod 43 is slidably connected in a connecting drive slot 46. The connecting drive slot 46 is provided in the rotating plate 32. A driving protrusion 47 is fixedly connected in the rotating plate 32.

[0044] When the rotating plate 32 rotates under the action of the pressure torsion spring 311, the driving protrusion 47 arranged in the pressure torsion spring 311 will abut the connecting rod 43 in the base 11, driving the connecting rod 43 and the electrical connection block 42 fixedly connected thereto to slide upward, so that the top of the electrical connection block 42 and the bottom of the anti-foolproof plug-in block 14 abut against each other. At the same time, this abutment ensures the stability of the connection between the two. At this time, the data received by the port block 12 can be transmitted through the anti-foolproof plug-in block 14, the power-on limiting device 5, the connecting rod 43 and the data transmission component 6. Through this design, it can be effectively guaranteed that the data transmission is carried out after the base 11 and the port block 12 are fixedly connected, thereby ensuring the stability of the data transmission process.

[0045] Example 3: This example is an explanation based on Example 2. For details, please refer to Figures 1 to 8 A power-on limiting device 5 is provided in the electrical connection block 42, and the power-on limiting device 5 includes a positioning plug-in slot 51 opened in the fool-proof plug-in block 14, a limiting slide slot 52 is opened in the electrical connection block 42, and a limiting slide plate 53 is slidably connected in the limiting slide slot 52, and a power-on rod 54 is fixedly connected to the top of the limiting slide plate 53, and the other end of the power-on rod 54 is plugged into the positioning plug-in slot 51, and a return spring 55 is fixedly connected to the bottom of the limiting slide plate 53, and the other end of the return spring 55 is installed in the limiting slide slot 52, and the bottom of the limiting slide slot 52 is connected with a hydraulic channel 58, and the hydraulic channel 58 includes a channel opened in the electrical connection block 42 and the base 11 and a hose connecting the two channels, and the other end of the hydraulic channel 58 is connected to the locking limit slot 23.

[0046] A connecting telescopic inner rod 56 is fixedly connected to the bottom of the limiting slide plate 53 . The connecting telescopic inner rod 56 is slidably connected in a connecting telescopic outer shell 57 . The connecting telescopic outer shell 57 is fixedly connected in the electrical connection block 42 .

[0047] The design of the power-on limiting device 5 further ensures data transmission, which can only be carried out after the locking device 2 locks the base 11 and the port block 12. When the locking plug plate 24 is inserted into the locking plug slot 21, the locking limit plate 25 at the bottom of the locking plug plate 24 slides synchronously. Since the side of the locking limit slot 23 away from the locking spring 26 is filled with hydraulic oil, and the side of the locking limit slot 23 filled with hydraulic oil is connected to the limiting slide slot 52 through the hydraulic channel 58, the sliding of the locking limit slot 23 drives the limiting slide plate 53 in the limiting slide slot 52 to slide upward synchronously, so that the fixed connection at the top of the limiting slide plate 53 The limiting slot 52 is inserted into the positioning slot 51. Since an electrical conductive sheet is installed on the top of the limiting slot 52 and in the positioning slot 51, through this connection, the data received by the port block 12 can be transmitted to the analysis instrument through the electrical connection block 42, the connecting rod 43 and the data transmission component 6 through the contact between the positioning slot 51 and the limiting slot 52, and the connection between the telescopic inner rod 56 and the telescopic outer shell 57 at the bottom of the limiting slot 52. Through this design, it is further ensured that the data transmission is carried out after the base 11 and the port block 12 are fixed, which further ensures the stability of data transmission.

[0048] A data transmission component 6 is provided in the rotating plate 32, and the data transmission component 6 includes a fold line ring groove 61 opened in the rotating plate 32, a fold line transfer ring 62 is installed in the fold line ring groove 61, the bottom of the fold line transfer ring 62 is connected to the data receiving rod 63, the data receiving rod 63 is set in the data receiving groove 64, and the data receiving groove 64 is opened in the base 11.

[0049] The design of the data transmission component 6 plans the data transmission line, effectively ensuring the connection between data transmission, receiving data through the port block 12, and transmitting the data to the analytical instrument connected to the bottom of the data receiving rod 63 through the sequence of the anti-foolproof plug-in block 14, the power-on rod 54, the limiting slide 53, the connecting telescopic inner rod 56, the connecting telescopic outer shell 57, the electrical connection block 42, the connecting rod 43, the folded line transmission ring 62 and the data receiving rod 63.

[0050] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
