Description

Technical Field

[0001] This utility model relates to the field of vibrating wire acquisition technology, specifically to a vibrating wire acquisition device with a stable connection. Background Technology

[0002] A vibrating wire data acquisition unit is a device used to collect, process, and analyze data from vibrating wire sensors. It can convert and calculate the frequency signals output from multiple vibrating wire sensors, transforming them into corresponding physical quantities. These physical quantities are then transmitted to host computer software or a cloud platform via wired (RS485) or wireless (e.g., 4G / LoRa) methods. Because the acquisition unit needs to be continuously connected to and read signals from the vibrating wire sensors, it is typically installed together with the sensors at outdoor construction sites, making it susceptible to impacts or human dragging. Existing data cables are fixedly connected to connectors, which are threaded to the acquisition unit. This connection method makes the data cable prone to breakage from the connector when the acquisition unit is dragged or impacted. Therefore, a more robust vibrating wire data acquisition unit is needed to address these issues. Utility Model Content

In outdoor environments, water and dust can easily enter, causing damage to the data acquisition device. This utility model improves the sealing of the first and second housings by setting up a first connecting mechanism and a second connecting mechanism, so that the external connecting wires are not directly connected to the circuit board, thus preventing water and dust from entering and extending the life of the data acquisition device. At the same time, the first and second connecting mechanisms have a certain amount of room for movement, so that the connector is not easily subjected to excessive tension and breakage when the data acquisition device is dragged.

[0013] (2) Existing connectors use threads for connection. Since the connector and housing are usually made of plastic, the threads are prone to wear and stripping, which leads to loosening of the connection. Secondly, the threaded connection requires multiple turns during installation, which is not convenient. Moreover, the threaded connection is not easy to install properly and is prone to loosening. This utility model can be installed by insertion and single rotation, which is convenient to operate. The first limit device is used to limit the position and prevent loosening. At the same time, it can assist the installer in installing the connector properly. Attached Figure Description

[0022] Reference Figures 1-6As shown, the present invention provides a stable vibrating wire acquisition device, comprising a first housing 1, a second housing 2, a sealing ring 3, multiple first connecting mechanisms 4, and second connecting mechanisms 5; the first housing and the second housing are connected by multiple first screws 6; the sealing ring is fixedly disposed on the first housing and in contact with the second housing; the first connecting mechanisms are symmetrically disposed on both sides of the first housing; the second connecting mechanisms are disposed on the first housing; the first connecting mechanism includes a first sliding component 41 and a first rotating component 42; the first sliding component is disposed on the first housing; the first rotating component is in contact with the first sliding component; after the first housing and the second housing are connected by the first screws, the sealing ring will be compressed, and the first housing... The first housing and the second housing fit more tightly with the sealing ring, improving sealing performance. Multiple first connecting mechanisms are used to connect RS485 signal lines; the second connecting mechanism is used to connect vibrating wire sensors. Existing connecting lines are directly connected to the circuit board inside the first housing, resulting in poor sealing of the data acquisition instrument. In outdoor environments, water and dust can easily enter, causing damage to the data acquisition instrument. This invention improves the sealing performance of the first and second housings by setting up first and second connecting mechanisms, so that the external connecting lines are not directly connected to the circuit board, preventing water and dust from entering and extending the life of the data acquisition instrument. At the same time, the first and second connecting mechanisms have a certain amount of room for movement, so that the connectors are not easily subjected to excessive tension and breakage when the data acquisition instrument is dragged.

[0023] Specifically, the first sliding assembly includes a first base 411, a first slide groove 412, multiple second slide grooves 413, a first sliding seat 414, multiple first sliders 415, a first spring 416, and a first contact 417. The first base is fixedly disposed inside the first housing and connected to the inner wall of one side of the first housing. The first slide groove is fixedly disposed on the first base and penetrates the first housing. The multiple second slide grooves are circumferentially fixedly disposed on the first base at equal intervals. The first sliding seat is slidably disposed on the first slide groove. The multiple first sliders are circumferentially fixedly disposed on the first sliding seat at equal intervals and fit against the second slide groove. One end of the first spring is fixedly disposed on the first sliding seat and the other end is fixedly disposed on the first housing. The first contact is fixedly disposed on one end of the first sliding seat. When the external connecting line is subjected to excessive tension, the first sliding seat can slide on the first slide groove, the first spring is stretched, and the first sliding seat has a certain amount of room for movement, which can prevent the external connecting line from breaking when subjected to excessive tension. The second slide grooves and the first sliders are used for limiting movement.

[0024] Specifically, the first rotating assembly includes a first connector 421, a second contact 422, multiple third slide grooves 423, multiple fourth slide grooves 424, multiple second sliders 425, and a first limiting device 426; the second contact is fixedly disposed on the first connector and fits against the first contact; the multiple third slide grooves are circumferentially fixedly disposed on the first sliding seat at equal intervals; the multiple fourth slide grooves are circumferentially fixedly disposed on the first sliding seat at equal intervals; the fourth slide grooves are connected end-to-end with the third slide grooves; the multiple second sliders are circumferentially fixedly disposed on the first connector and can slide along the third and fourth slide grooves; the first limiting device is disposed on the first sliding seat; existing connections The connector uses a threaded connection. Since the connector and housing are usually made of plastic, the threads are prone to wear and stripping, leading to loosening. Furthermore, threaded connections require multiple tightening operations, which is inconvenient, and they are difficult to install properly, easily resulting in loosening. This device uses insertion and a single rotation for installation, making it convenient. The first limiting device is used to limit the movement and prevent loosening, while also assisting the installer in installing the connector correctly. The third and fourth sliding grooves are L-shaped; the width of the fourth sliding groove is the same as the second slider. During installation, align the second slider with the third sliding groove, insert it to the bottom of the third sliding groove, and then rotate the first connector to allow the second slider to enter the fourth sliding groove.

[0026] Specifically, the second slider is a cylindrical rod; one end of the second slider is provided with a hemispherical rod head.

[0027] Specifically, the first limiting head is an arc-shaped cylindrical rod; one end of the first limiting head is provided with a hemispherical rod head; the first limiting head contacts the second slider; the top of the first limiting head is hemispherical, and the bottom of the second slider is hemispherical. When the second slider is inserted, it can squeeze and push the first limiting head into the fifth slide groove; when the second slider slides to the bottom of the third slide groove, it will squeeze the first limiting head, causing the first limiting head to enter the fifth slide groove. The second spring is compressed. When the second slider enters the fourth slide groove, the second spring pushes the first limiting head into the third slide groove, and at the same time contacts the second slider. The elastic force of the second spring can prevent the first connecting head from rotating.
