Description

Technical Field

[0001] This utility model relates to the technical field of pressure transmitter housing structure, and in particular to a high-sealing explosion-proof wireless pressure transmitter housing structure. Background Technology

[0002] The high-sealing explosion-proof wireless pressure transmitter housing structure refers to a protective housing system specifically designed for wireless pressure transmitters, possessing high-level sealing performance and explosion-proof functions. Its core function is to ensure the stable operation of core components such as pressure sensing elements and wireless signal transmission modules inside the transmitter. Relying on a structural design that meets explosion-proof standards, it effectively suppresses potential ignition sources such as electrical sparks and high temperatures generated inside the housing from contacting the external explosive environment, preventing the risk of explosion.

[0003] However, in the existing high-sealing explosion-proof wireless pressure transmitter housing structure, the connection structure between the protective housing and the main housing of the display area is prone to increased gaps or loosening of threads during long-term use due to equipment operation vibration and changes in the external environment. This makes it difficult for the protective housing to fit tightly against the main housing, which not only damages the original sealing performance, allowing external media such as dust and moisture to easily enter through the loose parts, but also weakens the integrity of the explosion-proof structure, making it difficult to continuously ensure the stable operation of the equipment in high-risk environments.

[0004] To address this, a high-sealing explosion-proof housing structure for a wireless pressure transmitter is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a high-sealing explosion-proof wireless pressure transmitter housing structure. This structure solves the problem that, in the long-term use of existing high-sealing explosion-proof wireless pressure transmitter housing structures, the connection between the protective housing and the main housing of the display area is prone to increased gaps or loosening of threads due to equipment vibration and changes in the external environment. This makes it difficult for the protective housing to fit tightly against the main housing, which not only damages the original sealing performance, allowing external media such as dust and moisture to easily enter through the loosened parts, but also weakens the integrity of the explosion-proof structure, making it difficult to continuously ensure the stable operation of the equipment in high-risk environments.

[0010] Preferably, a first locking block is fixedly connected to the inner wall of the card holder assembly, and the surface of the first locking block engages with the inner wall of the fixing frame.

[0011] Preferably, a second locking block is fixedly connected to the inner wall of the card holder assembly, and the surface of the second locking block engages with the inner wall of the device body.

[0012] Preferably, a pre-mounted bracket is rotatably connected to the surface of the card holder assembly, the surface of the pre-mounted bracket engages with the inner wall of the fixed bracket, and the surface of the pre-mounted bracket engages with the inner wall of the device body.

[0013] Preferably, a knob is movably connected to the inner wall of the card holder assembly, and the surface of the knob is threadedly connected to the inner wall of the pre-installation frame.

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

[0015] 1. This application incorporates a protective mechanism. The transparent panel within the protective mechanism is made of high-strength explosion-proof transparent material (such as explosion-proof glass or high-strength polycarbonate). This ensures that personnel can observe the operating status of the device body through the transparent panel while also resisting external impacts and preventing breakage.

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.

[0025] Please see Figure 1-6 The present invention provides the following technical solution:

[0026] A high-sealing explosion-proof wireless pressure transmitter housing structure includes a device body 1, a protective mechanism 2 threadedly connected to the surface of the device body 1, a clamping assembly 3 movably connected to the surface of the protective mechanism 2, the inner wall of the clamping assembly 3 movably connected to the surface of the device body 1, a rubber ring 4 bonded to the inner wall of the protective mechanism 2, the surface of the rubber ring 4 engaging with the inner wall of the device body 1, the protective mechanism 2 includes a transparent plate 201, a mounting bracket 202 fixedly connected to the surface of the transparent plate 201, a fixing bracket 203 fixedly connected to the surface of the mounting bracket 202, and the inner wall of the fixing bracket 203 threadedly connected to the surface of the device body 1.

[0027] In this embodiment: By setting up a protective mechanism 2, the transparent plate 201 in the protective mechanism 2 is made of a high-strength explosion-proof transparent material (such as explosion-proof glass or high-strength polycarbonate). This ensures that the staff can observe the operating status of the device body 1 through the transparent plate 201, while also resisting external impacts and preventing breakage. At the same time, it forms a stable protective frame with the mounting bracket 202 and the fixing bracket 203. The fixing bracket 203 is threadedly connected to the surface of the device body 1, which enables reliable assembly of the protective mechanism 2 and the housing. This ensures that the protective mechanism 2 effectively covers the data display area of ​​the device body 1, and the rubber ring 4 bonded to the inner wall of the protective mechanism 2 can... The device body 2 fits tightly against the inner wall of the device body 1, filling the connection gap between the fixing frame 203 and the device body 1. This effectively prevents external dust, water vapor, corrosive media, etc., from entering the interior of the fixing frame 203, ensuring that the internal components of the fixing frame 203 are protected from external environmental interference. By setting the clamping assembly 3, the clamping assembly 3 can drive the limiting component to form an auxiliary limit on the device body 1 and the fixing frame 203, further enhancing the stability of the threaded connection between the fixing frame 203 and the device body 1, preventing the fixing frame 203 from loosening unexpectedly under long-term vibration, temperature changes, and other working conditions, and ensuring the reliability of the connection between the protective mechanism 2 and the device body 1.

[0028] Specifically, such as Figure 3 As shown, the surface of the rubber ring 4 is bonded to the inner wall of the fixing frame 203, and the rear side of the fixing frame 203 is in contact with the front side of the device body 1.

[0029] Specifically, such as Figure 3 , Figure 6As shown, the inner wall of the fixing frame 203 is provided with a threaded groove 5 that is used in conjunction with the device body 1, and the surface of the device body 1 is provided with an external thread 6.

[0030] Specifically, such as Figure 3 , Figure 6 As shown, the inner wall of the fixing frame 203 is provided with a first sealing groove 7 that cooperates with the rubber ring 4, and the inner wall of the device body 1 is provided with a second sealing groove 8 that cooperates with the rubber ring 4.

[0031] In this embodiment: the surface of the rubber ring 4 is bonded to the inner wall of the fixing frame 203, which facilitates the fixing frame 203 to drive the rubber ring 4 to be snapped onto the inner wall of the device body 1, thus ensuring a high sealing effect. The threaded groove 5 opened on the inner wall of the fixing frame 203 and the external thread 6 provided on the surface of the device body 1 facilitate the fixing frame 203 to be assembled onto the surface of the device body 1 through the external thread 6, which facilitates the quick installation of the fixing frame 203. The first sealing groove 7 opened on the inner wall of the fixing frame 203 facilitates the sealing ring to be bonded to the inner wall of the fixing frame 203 through the first sealing groove 7. The second sealing groove 8 opened on the inner wall of the device body 1 facilitates the rubber ring 4 to be snapped onto the inner wall of the device body 1 through the second sealing groove 8.

[0032] Specifically, such as Figure 5 As shown, a first card block 9 is fixedly connected to the inner wall of the card holder assembly 3, and the surface of the first card block 9 engages with the inner wall of the fixing frame 203.

[0033] Specifically, such as Figure 5 As shown, a second card block 10 is fixedly connected to the inner wall of the card holder assembly 3, and the surface of the second card block 10 is engaged with the inner wall of the device body 1.

[0034] In this embodiment: by setting the first card block 9 and the second card block 10, the first card block 9 and the second card block 10 are respectively fixed to the position of the card holder assembly 3 during use, so that the card holder assembly 3 can drive the first card block 9 and the second card block 10 to restrict the position of the fixing frame 203 and the device body 1, so as to avoid the fixing frame 203 from shifting during long-term use and make it convenient for the user to use.

[0035] Specifically, such as Figure 4 As shown, a pre-installation frame 11 is rotatably connected to the surface of the card holder assembly 3. The surface of the pre-installation frame 11 is engaged with the inner wall of the fixing frame 203, and the surface of the pre-installation frame 11 is engaged with the inner wall of the device body 1.

[0036] Specifically, such as Figure 4 As shown, a knob 12 is movably connected to the inner wall of the card holder assembly 3, and the surface of the knob 12 is threadedly connected to the inner wall of the pre-installation frame 11.

[0037] In this embodiment: by setting a pre-installation frame 11, the device enters the pre-installation position through the pre-installation frame 11 during use, so that the pre-installation frame 11 is snapped into the inner wall of the fixing frame 203 and the device body 1. Then, the clamping assembly 3 rotates on the inner wall of the pre-installation frame 11, so that the clamping assembly 3 drives the first clamping block 9 and the second clamping block 10 to snap into the inner wall of the fixing frame 203 and the device body 1. Then, the knob 12 rotates on the inner wall of the clamping assembly 3 and the pre-installation frame 11, so as to restrict the position of the clamping assembly 3 and the pre-installation frame 11, enhance the anti-loosening ability of the overall connection structure, and facilitate the use of the user.

[0038] Working Principle: During the use of the device body 1, a protective mechanism 2 is installed. The transparent plate 201 in the protective mechanism 2 is made of high-strength explosion-proof transparent material (such as explosion-proof glass or high-strength polycarbonate). This ensures that personnel can observe the operating status of the device body 1 through the transparent plate 201, while also resisting external impacts and preventing breakage. Simultaneously, it forms a stable protective frame with the mounting bracket 202 and the fixing bracket 203. The threaded connection between the fixing bracket 203 and the surface of the device body 1 ensures reliable assembly of the protective mechanism 2 and the housing, ensuring effective coverage of the data display area of ​​the device body 1 by the protective mechanism 2. Furthermore, the inner wall of the protective mechanism 2 is bonded... The rubber ring 4 can fit tightly against the inner wall of the device body 1, filling the connection gap between the fixing frame 203 and the device body 1, effectively blocking external dust, water vapor, corrosive media and other substances from entering the interior of the fixing frame 203, and protecting the internal components of the fixing frame 203 from external environmental interference. By setting the clamping component 3, the clamping component 3 can drive the limiting component to form an auxiliary limit on the device body 1 and the fixing frame 203, further enhancing the stability of the threaded connection between the fixing frame 203 and the device body 1, avoiding the fixing frame 203 from loosening unexpectedly under long-term vibration, temperature change and other working conditions, and ensuring the reliability of the connection between the protective mechanism 2 and the device body 1.

[0039] 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.
