Description

Technical Field

[0001] This utility model relates to the field of pressure monitoring sensor packaging and testing technology, specifically a packaging and testing device for a water meter pressure monitoring sensor. Background Technology

[0002] In the production process of water meter pressure monitoring sensors, the packaged sensor needs to undergo pressure testing to verify its structural stability and pressure monitoring accuracy. This is a key step to ensure the reliable operation of the sensor in the future.

[0003] Existing sensor packaging and testing devices often use rigid clamping mechanisms for fixing in practical applications. This makes it difficult to achieve stable clamping when dealing with sensors of different diameters, thicknesses, or shapes. Furthermore, unloading after testing is inconvenient, with low efficiency in removing individual sensors. After batch testing, each sensor needs to be manually disassembled individually, which is cumbersome and affects testing efficiency. Therefore, there is a need to improve the packaging and testing device for water meter pressure monitoring sensors to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a packaging and testing device for a water meter pressure monitoring sensor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a packaging and testing device for a water meter pressure monitoring sensor, comprising a support frame, a fixing mechanism, and a feeding mechanism. A receiving terminal is fixedly installed on the side of the support frame, and a sliding frame is slidably installed on the front of the support frame. An alarm light is provided on the front of the sliding frame, and a pressing column is fixedly installed at the bottom of the sliding frame. An electric push rod with its output end fixedly installed on the inner side of the support frame is also fixedly installed on the sliding frame. The fixing mechanism includes a fixing frame, a pressing frame, an elastic wing, and a rubber pad. The fixing frame is fixedly installed on... At the top of the support frame, the extrusion frame is slidably installed inside the fixed frame. A rubber pad is fixedly installed on the inner side of the extrusion frame. One end of the elastic wing is fixedly installed to the extrusion frame, and the free end abuts against the rubber pad. The feeding mechanism includes a push plate, a triangular push block, and a pull plate. The push plate is slidably installed inside the fixed frame. The triangular push block is fixedly installed at the bottom of the push plate, and its inclined surface is in contact with the extrusion frame. The pull plate is slidably installed at the top of the fixed frame and is located on the back of the push plate. The opening and closing of a single extrusion frame is controlled by the displacement of the push plate, and the simultaneous opening and closing of all extrusion frames is controlled by the displacement of the pull plate.

[0006] Preferably, the fixing mechanism further includes a first spring, which is fixedly installed on the inner wall of the fixing frame. The extrusion frame is fixedly installed with the first spring. A first groove is provided at the corresponding position of the fixing frame and the extrusion frame. A rotating column is rotatably installed at one end of the extrusion frame that passes through the first groove.

[0007] Preferably, the feeding mechanism further includes a second spring, which is fixedly installed on the inner wall of the fixed frame. The push plate is fixedly installed with the second spring. A second sliding groove is provided at the corresponding position of the fixed frame and the push plate. The push plate passes through the second sliding groove and is fixedly installed with a triangular push block. The inclined surface of the triangular push block is in contact with the rotating column. A third sliding groove is provided at the corresponding position of the top of the fixed frame and the pull plate. The third spring is located inside the third sliding groove and is located between the pull plate and the fixed frame.

[0008] Preferably, the elastic wing is composed of multiple overlapping elastic units, and the connection parts of adjacent units form an overlapping area, constituting a continuous layered elastic contact structure.

[0009] Preferably, the pull plate is connected to the back of all the push plates by a rigid connecting rod to form a synchronous displacement structure.

[0010] Compared with the prior art, this utility model provides a packaging and testing device for a water meter pressure monitoring sensor, which has the following advantages:

[0011] 1. The packaging and testing device for the water meter pressure monitoring sensor uses a compression frame within a fixed frame, with a first spring providing elastic preload. This, combined with an inner rubber pad and fish-scale-stacked elastic fins, enables adaptive fixing of sensors of different sizes. When the sensor is placed within the fixed frame, the rubber pad is compressed, causing the elastic fins to deform. The layered contact structure of the elastic fins ensures that the rubber pad fits tightly against the sensor surface, improving fixing stability and avoiding damage to the sensor from rigid contact. The elasticity of the first spring can adapt to the fixing requirements of sensors of different specifications, enhancing the versatility of the device.

[0012] 2. The packaging and testing device for the water meter pressure monitoring sensor uses the inclined surface of the triangular pusher to push the rotating column at the bottom of the extrusion frame, causing the extrusion frame to open outward against the spring force of the first spring. This facilitates the quick removal of a single sensor after testing, making the operation convenient. The pull plate is connected to all the push plates, and pulling the pull plate can synchronously drive all the push plates to move, enabling all the extrusion frames to open at the same time. This meets the centralized unloading requirements after batch testing, significantly reducing unloading operation time and improving overall testing efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Example: Figures 1-5As shown, this utility model provides a technical solution: a packaging and testing device for a water meter pressure monitoring sensor, including a support frame 1, a fixing mechanism 2, and a feeding mechanism 3. A receiving terminal 11 is fixedly installed on the side of the support frame 1, a sliding frame 5 is slidably installed on the front of the support frame 1, an alarm light 51 is provided on the front of the sliding frame 5, a pressing column 52 is fixedly installed at the bottom of the sliding frame 5, and an electric push rod 4 with its output end fixedly installed on the inner side of the support frame 1 is fixedly installed on the inner side of the support frame 1. The fixing mechanism 2 includes a fixing frame 21, a pressing frame 23, an elastic wing 24, and a rubber pad 25. The fixing frame 21 is fixedly installed on the top of the support frame 1, the pressing frame 23 is slidably installed inside the fixing frame 21, and the rubber pad 25 is fixedly installed on the inner side of the pressing frame 23. One end of the elastic wing 24 is fixedly installed on the pressing frame 23, and the free end abuts against the rubber pad 25. The elastic wing 24 consists of multiple overlapping... The unit is composed of elastic units, and the connection parts of adjacent units form an overlapping area, forming a continuous layered elastic contact structure. The feeding mechanism 3 includes a push plate 32, a triangular push block 33, and a pull plate 35. The push plate 32 is slidably installed inside the fixed frame 21. The triangular push block 33 is fixedly installed at the bottom of the push plate 32 and its inclined surface is in contact with the extrusion frame 23. The pull plate 35 is slidably installed at the top of the fixed frame 21 and is located on the back of the push plate 32. The pull plate 35 is connected to the back of all the push plates 32 through a rigid connecting rod to form a synchronous displacement structure. The opening and closing of a single extrusion frame 23 is controlled by the displacement of the push plate 32. The simultaneous opening and closing of all the extrusion frames 23 is controlled by the displacement of the pull plate 35. The extrusion frames 23 in the fixed frame 21 are provided with elastic pre-tightening force by the first spring 22. With the help of the inner rubber pad 25 and the fish-scale stacked elastic winglets 24, adaptive fixing of sensors of different sizes can be achieved.

[0023] Furthermore, such as Figures 2-4 As shown, the fixing mechanism 2 also includes a first spring 22, which is fixedly installed on the inner wall of the fixing frame 21. The compression frame 23 is fixedly installed with the first spring 22. A first groove 211 is provided at the corresponding position of the fixing frame 21 and the compression frame 23. A rotating column 231 is rotatably installed at one end of the compression frame 23 that passes through the first groove 211. When the sensor is placed in the fixing frame 21, the rubber pad 25 is compressed and pushes the elastic wing 24 to deform. The layered contact structure of the elastic wing 24 ensures that the rubber pad 25 is tightly attached to the sensor surface, which not only improves the fixing stability but also avoids damage to the sensor caused by rigid contact. The elastic force of the first spring 22 can adapt to the fixing requirements of sensors of different specifications, enhancing the versatility of the device.

[0024] Furthermore, such as Figures 2-4As shown, the feeding mechanism 3 also includes a second spring 31, which is fixedly installed on the inner wall of the fixed frame 21. The push plate 32 is fixedly installed with the second spring 31. A second groove 321 is provided at the corresponding position of the fixed frame 21 and the push plate 32. The push plate 32 passes through the second groove 321 and is fixedly installed with the triangular push block 33. The inclined surface of the triangular push block 33 is in contact with the rotating column 231. A third groove 351 is provided at the corresponding position of the top of the fixed frame 21 and the pull plate 35. The third spring 34 is located inside the third groove 351 and is located in the pull plate 35. Between plate 35 and fixed frame 21, the inclined surface of triangular push block 33 pushes the rotating column 231 at the bottom of extrusion frame 23, so that extrusion frame 23 overcomes the elastic force of first spring 22 and opens outward, making it easy to quickly remove a single sensor that has been tested. The operation is convenient. Pull plate 35 is connected to all push plates 32 through rigid connecting rod. Pulling pull plate 35 can drive all push plates 32 to move simultaneously, so that all extrusion frames 23 open at the same time, which meets the centralized unloading requirements after batch testing, greatly reduces unloading operation time, and improves overall testing efficiency.

[0025] It should be noted that the pressure sensing element, signal transmission line, and external data acquisition equipment used to monitor the pressure value of the water meter pressure monitoring sensor are existing technologies. During the specific testing of this device, when the electric push rod 4 drives the pressure column 52 to apply pressure to the fixed sensor, the pressure sensing element inside the sensor transmits the sensed pressure signal to the receiving terminal 11 through its own signal transmission line. The receiving terminal 11 can display the pressure value borne by the sensor in real time. It can not only detect the difference between the pressure sensor value and the actual pressure (i.e., the pressure of the electric push rod 4), but also achieve precise control of the output pressure of the electric push rod 4 and trigger the alarm light 51 when the pressure is abnormal. (The receiving terminal 11 includes a built-in microcontroller and a display screen on its surface. The output signal of the pressure sensor is sent to the microcontroller, which displays it on the display screen and can set preset values. When the electric push rod 4 applies force to a certain extent, it automatically stops operating. It can also activate the alarm light 51 when the error is large or the pushing pressure is too high.)

[0026] In actual operation, when this device is used, the water meter pressure sensor to be tested is connected to an external power source and a receiving terminal 11, and then placed inside the fixed frame 21. The sensor presses the rubber pads 25 to both sides, and the rubber pads 25 push the pressing frame 23 to move outward, thereby allowing the first spring 22 and the elastic wing 24 to store energy. One end of the elastic wing 24 is fixedly installed with the pressing frame 23, and the free end abuts against the rubber pad 25. The elastic wing 24 is stacked in a fish scale pattern, so that the rubber pad 25 can fit tightly against the sensor surface, thereby allowing the fixing mechanism 2 to adapt to different sensors.

[0027] The electric push rod 4 is activated, which pulls down the sliding frame 5. The pressure sensor is pressed down by the pressure column 52. First, the pressure of the electric push rod 4 is controlled by the receiving terminal 11. When the value displayed on the surface of the pressure sensor is too large compared with the preset pressure, the alarm light 51 sounds. At this time, the push plate 32 at the corresponding position is pulled outward. When the push plate 32 is pulled, the second spring 31 is deformed and stored. The triangular push block 33 fixedly installed at the bottom of the push plate 32 pushes the rotating column 231 rotatably installed at the bottom of the extrusion frame 23 that is in contact with its inclined surface to rotate, thereby opening the extrusion frame 23 outward. Then, the sensor at the corresponding position is pushed out by the push plate 32. After the packaging and testing of this batch of sensors is completed, the pull plate 35 located on the back of all push plates 32 is pulled. The pull plate 35 causes all push plates 32 to move outward, thereby opening all extrusion frames 23 and removing all the tested sensors at the same time.

[0028] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
