Description

Technical Field

[0001] This utility model relates to the field of self-powered wireless sensor network technology, and in particular to a plug-in self-powered wireless pressure transmitter. Background Technology

[0002] In the field of industrial automation pressure monitoring, traditional pressure transmitters generally suffer from complex wiring, reliance on external power supply leading to high installation and maintenance costs, and difficulty in adapting to mobile or remote monitoring scenarios. With the increasing demand for remote real-time monitoring, pressure transmitters that simplify installation through plug-in structure, solve power supply problems through self-powered technology, and integrate wireless transmission functions have become an important development direction to break through traditional limitations.

[0003] In the existing technology, the power supply interface design of existing pressure transmitters has problems such as rudimentary sealing and protection structure, which makes them susceptible to external dust and liquid intrusion, affecting the reliability of power supply. At the same time, the lack of self-cleaning function when plugging and unplugging the interface makes the contacts easy to accumulate dirt. Furthermore, the connection and disassembly between the interface and the transmitter body is inconvenient and maintenance efficiency is low.

[0004] To address this, a plug-in self-powered wireless pressure transmitter is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a plug-in self-powered wireless pressure transmitter that can solve the problems of unreliable sealing and low maintenance efficiency in existing systems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plug-in self-powered wireless pressure transmitter, comprising a transmitter body, a plug interface fixedly connected to the rear side of the transmitter body, a protective mechanism movably connected to the rear side of the transmitter body, the protective mechanism being disposed outside the plug interface, a reset component movably connected to the outer side of the protective mechanism, the protective mechanism including a sealing box, the sealing box being fixedly connected to the rear side of the transmitter body, and the plug interface being disposed inside the sealing box, a sealing cover rotatably connected to the rear side of the sealing box, an installation component movably connected to the outer side of the sealing cover, and a soft plug movably connected to the inner side of the installation component.

[0007] Preferably, the reset assembly includes a sealing groove on the rear side of the sealing box, and limit posts are fixedly connected to both sides of the top of the sealing box.

[0008] Preferably, a sealing block is fixedly connected to the front side of the sealing cover, and the sealing block is snapped into the inside of the sealing groove.

[0009] Preferably, torsion springs are fitted on both sides of the top of the sealing cover, and the other end of the torsion springs is fixedly connected to the inside of the limiting post.

[0010] Preferably, the mounting assembly includes a mounting plate, which is inserted into the inner side of the sealing cover. Both sides of the sealing cover are fixedly connected to brackets, and each bracket is fixedly connected to a sliding rod on the side near the mounting plate.

[0011] Preferably, a clamping block is slidably connected to the outer side of the slide rod, the clamping block is disposed on both sides of the mounting plate, and a compression spring is fixedly connected to the opposite side of the clamping block and the bracket.

[0012] Preferably, the clamping block is fixedly connected to the side of the mounting plate near the mounting plate.

[0013] Preferably, slots are provided on both sides of the rear side of the mounting plate, and the plug is inserted into the inside of the slot.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application, by setting up a protective mechanism, can place the connector inside a sealed box with a sealing cover on the outside of the transmitter body. Under normal conditions, the sealing cover is closed to isolate external air and prevent dust and liquid from entering, thus solving the problem of the rudimentary sealing protection of existing power supply interfaces. The elastic soft plug inside the sealing cover will repeatedly rub the inside of the sealing box during the opening and closing process, which can stick to the dust that enters when plugging in power, achieving self-cleaning. This solves the problem of easy dirt accumulation on the contacts due to the lack of self-cleaning function when plugging and unplugging the interface. When replacing the soft plug, simply open the clamp on the outside of the sealing cover, insert the soft plug with the mounting plate, and then release the clamp. It can be fixed by the spring. The operation is convenient and solves the problems of inconvenient disassembly and assembly of the interface and transmitter body and low maintenance efficiency, effectively ensuring the reliability of power supply.

[0016] 2. This application incorporates a reset component. By attaching torsion springs to both sides of the sealing cover's rotating shaft and connecting the other end to the limiting post on the outside of the sealing box, the torsion springs tighten and generate rotational force when the sealing cover rotates. The sealing cover automatically closes after the operator releases their grip. Simultaneously, this reset action allows the sealing block and sealing groove between the sealing cover and the sealing box to engage more quickly and stably, rapidly restoring the sealing state. This not only solves the potential problem of sealing failure due to operators forgetting to close the sealing cover, but also improves the potential problems of slow sealing cover closure speed and insufficient fit stability affecting the sealing effect, further enhancing the sealing performance and optimizing the plug-in self-powered wireless pressure transmitter.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A plug-in self-powered wireless pressure transmitter includes a transmitter body 1, a plug interface 2 fixedly connected to the rear side of the transmitter body 1, a protective mechanism 3 movably connected to the rear side of the transmitter body 1, the protective mechanism 3 being disposed outside the plug interface 2, a reset component 4 movably connected to the outer side of the protective mechanism 3, the protective mechanism 3 including a sealing box 31, the sealing box 31 being fixedly connected to the rear side of the transmitter body 1, and the plug interface 2 being disposed inside the sealing box 31, a sealing cover 32 being rotatably connected to the rear side of the sealing box 31, an installation component 33 movably connected to the outer side of the sealing cover 32, and a soft plug 34 movably connected to the inner side of the installation component 33.

[0026] In this embodiment: instead of exposing the connector 2 of the transmitter body 1 directly to the air, a sealed box 31 is installed on the outside of the transmitter body 1 housing, and the connector 2 is inside the sealed box 31. Normally, the sealing cover 32 seals the sealed box 31, isolating the connector 2 from the outside air. When in use, the sealing cover 32 is rotated to open and plug in the power supply. In addition, the side of the sealing cover 32 facing the inside of the sealed box 31 has a soft plug 34 made of elastic material. When the sealing cover 32 is closed, the soft plug 34 will squeeze the inside of the sealed box 31 to deform and fit the shape. When the sealing cover 32 is opened and closed, the soft plug 34 will rub the inside of the sealed box 31 like repeatedly pulling and rubbing, sticking the dust that enters when plugging in the power supply to the surface of the soft plug 34. Therefore, every time the sealing cover 32 is opened, as long as the soft plug 34 is cleaned or replaced, the inside of the sealed box 31 can be kept clean and isolated from the air. Moreover, the soft plug 34 is easy to replace. It can be quickly installed with the installation component 33 and can also be quickly disassembled in reverse.

[0027] Specifically, such as Figure 2 , Figure 5 As shown, the reset assembly 4 includes a sealing groove 41 on the rear side of the sealing box 31, and limit posts 42 are fixedly connected to both sides of the top of the sealing box 31.

[0028] Specifically, such as Figure 2 , Figure 5 As shown, a sealing block 43 is fixedly connected to the front side of the sealing cover 32, and the sealing block 43 is snapped into the inner side of the sealing groove 41.

[0029] Specifically, such as Figure 2 , Figure 5 As shown, torsion springs 44 are fitted on both sides of the top of the sealing cover 32, and the other end of the torsion springs 44 is fixedly connected to the inside of the limiting post 42.

[0030] In this embodiment: to prevent someone from forgetting to close the sealing cover 32, torsion springs 44 are fitted on both sides of the rotating shaft of the sealing cover 32. The other end of the torsion spring 44 is connected to the limiting post 42 on the outside of the sealing box 31. When the sealing cover 32 rotates, the torsion spring 44 will be tightened to generate a rebound force, so the sealing cover 32 can automatically close when released. Moreover, after this reset, the sealing block 43 and the sealing groove 41 between the sealing cover 32 and the sealing box 31 can be engaged more quickly and stably, thereby quickly restoring the sealing state and ultimately optimizing the plug-in self-powered wireless pressure transmitter.

[0031] Specifically, such as Figure 3 , Figure 4 As shown, the mounting assembly 33 includes a mounting plate 3301, which is inserted into the inner side of the sealing cover 32. Both sides of the sealing cover 32 are fixedly connected to brackets 3302, and the side of each bracket 3302 near the mounting plate 3301 is fixedly connected to a sliding rod 3303.

[0032] Specifically, such as Figure 3 , Figure 4 As shown, a clamping block 3304 is slidably connected to the outer side of the slide rod 3303. The clamping block 3304 is disposed on both sides of the mounting plate 3301. A compression spring 3305 is fixedly connected to the opposite side of the clamping block 3304 and the bracket 3302.

[0033] In this embodiment: When replacing the soft plug 34, first open the sealing cover 32, and push the two sets of clamps 3304 on the outside of the sealing cover 32 to both sides along the slide rod 3303. Then, insert the soft plug 34 supported by the mounting plate 3301 directly into the groove inside the sealing cover 32. The soft plug 34 should face the sealing box 31. After insertion, the protruding position of the mounting plate 3301 is on the outside of the sealing cover 32. Then, release the clamps 3304. Since the clamps 3304 will squeeze the compression spring 3305 between it and the bracket 3302 when pushed outward along the slide rod 3303, the clamps 3304 will quickly rebound, pressing against the mounting plate 3301 from both sides and allowing the plug 5 to be inserted into the inside of the mounting plate 3301. This completes the quick installation. The reverse operation allows for quick disassembly.

[0034] Specifically, such as Figure 4 As shown, the clamping block 3304 is fixedly connected to the insert block 5 on the side near the mounting plate 3301.

[0035] Specifically, such as Figure 4 As shown, slots 6 are provided on both sides of the rear side of the mounting plate 3301, and the plug 5 is inserted into the inside of the slot 6.

[0036] In this embodiment, the installation stability is further increased by insert block 5 and slot 6.

[0037] Working Principle: Existing pressure transmitter power supply interface designs suffer from inadequate sealing and protection structures, making them susceptible to external dust and liquid intrusion, thus affecting power supply reliability. Furthermore, the lack of self-cleaning during interface insertion and removal leads to easy accumulation of dirt on the contacts. Additionally, the connection and disassembly between the interface and the transmitter body are inconvenient, resulting in low maintenance efficiency. To avoid these issues, the transmitter body 1's connector 2 is no longer directly exposed to the air. Instead, a sealing box 31 is installed on the outer side of the transmitter body 1's outer shell, with the connector 2 located inside the sealing box 31. Under normal conditions, the sealing box 31 is sealed by the sealing cover 32, isolating the connector 2 from external air. When needed, simply rotate the sealing box 31 to open it. Then, power can be plugged in. During the above process, a soft plug 34 is provided on the side of the sealing cover 32 facing the inside of the sealing box 31. The soft plug 34 is made of elastic material. When the sealing cover 32 is closed, it can squeeze the inside of the sealing box 31 and deform, conforming to the shape of the inside of the sealing box 31. Therefore, during the above-mentioned flipping and opening, and flipping and sealing process, the soft plug 34 forms a state similar to repeated pulling, and repeatedly rubs the inside of the sealing box 31. This allows dust that enters the inside of the sealing box 31 during the power plugging process to be directly adhered to the surface of the soft plug 34. So, each time the sealing cover 32 is opened, only the soft plug 34 needs to be cleaned or replaced to ensure the condition of the inside of the sealing box 31. The system effectively isolates air and keeps the interior of the sealed box 31 clean. The soft plug 34 is also easy to replace. When it needs to be replaced, simply open the sealing cover 32 and push the two sets of clamps 3304 on the outside of the sealing cover 32 to both sides along the slide rod 3303. The soft plug 34, supported by the mounting plate 3301, is then directly inserted into the groove inside the sealing cover 32, with the soft plug 34 facing the sealed box 31. The protruding part of the mounting plate 3301 is located on the outside of the sealing cover 32 after insertion. Then, release the pressure on the two clamps 3304. As the clamps 3304 move outward along the slide rod 3303, they compress the spring 3305 between themselves and the bracket 3302, causing the clamps 3304 to quickly spring back from both sides. Contact the mounting plate 3301 and insert the plug 5 into the inside of the mounting plate 3301 to complete the quick installation; otherwise, disassemble quickly. In addition, to further improve the sealing effect and prevent personnel from forgetting to close the sealing cover 32, torsion springs 44 are sleeved on both sides of the rotating shaft of the sealing cover 32, and the other end of the torsion spring 44 is connected to the limiting post 42 on the outside of the sealing box 31. When the sealing cover 32 rotates, the torsion spring 44 is tightened to generate a rotational force, so that it will automatically close when the personnel release their hands. Through this reset, the sealing block 43 and the sealing groove 41 between the sealing cover 32 and the sealing box 31 can be engaged more quickly and stably, so as to quickly restore the sealing state. In summary, the plug-in self-powered wireless pressure transmitter is optimized.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
