Technical Field

[0001] This utility model relates to the field of temperature and humidity transmitter technology, and in particular to an explosion-proof temperature and humidity transmitter. Background Technology

[0002] A temperature and humidity transmitter is a device used to measure ambient temperature and relative humidity and convert the measured values ​​into standard electrical signals for transmission. It has wide applications in industrial control, agriculture, building automation, warehousing, meteorological monitoring, and HVAC systems.

[0003] In practical applications, existing temperature and humidity transmitters have relatively complete structures and functions, which can meet basic usage requirements. However, the following problems still exist:

[0004] In practical use, in order to prevent the electrical load generated by the device from causing flammable and explosive materials in the environment to explode, it is usually necessary to use a grounding wire to conduct the charge to the ground. However, the grounding wire is often placed around the external connecting cable, which makes it very easy for the grounding wire to get tangled with the connecting cable, thus causing the grounding wire to fail. It also makes it easy for the continuous cable to separate from the grounding wire during the pulling process, which is very inconvenient.

[0005] Therefore, this utility model provides an explosion-proof temperature and humidity transmitter. Utility Model Content

[0010] In a preferred embodiment, an arc-shaped plate is fixedly connected to the bottom of the device, and a U-shaped frame is fixedly connected to one side of the arc-shaped plate.

[0011] The technical effect of adopting the above-mentioned further solution is that, under the action of the arc plate, the grounding wire can be limited in conjunction with the U-shaped frame, so that the grounding wire can be limited inside the U-shaped frame in conjunction with the action of rubber round blocks and other components, thereby avoiding the grounding wire from getting tangled with connecting wires and other components, which could lead to detachment or affect conductivity.

[0025] 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.

[0026] like Figures 1-5 As shown, this embodiment provides a technical solution: an explosion-proof temperature and humidity transmitter, including a body 1, a sensor 2 installed at the bottom of the body 1, and a connecting wire 3 inserted at the bottom of the body 1; a grounding connection structure 4 is provided on one side of the body 1, the grounding connection structure 4 includes a threaded locking hole 43, the threaded locking hole 43 is opened on one side of the body 1, a threaded locking rod 44 is threadedly connected to the inner wall of the threaded locking hole 43, a terminal ring 45 is sleeved on the outer surface of the threaded locking rod 44, and a terminal frame 46 is fixedly connected to the bottom of the terminal ring 45; a disassembly and assembly fixing structure 5 is provided on one side of the body 1, the disassembly and assembly fixing structure 5 includes a circular hole 51, the circular hole 51 is opened on one side of the body 1, and a circular iron block 52 is fixedly connected to the inner wall of the circular hole 51. A first magnet 53 is magnetically fixed to one side of the iron block 52. A connecting block 55 is fixedly connected to one side of the first magnet 53. A second magnet 56 is fixedly connected to one side of the connecting block 55. By setting the grounding connection structure 4, under the action of the threaded locking rod 44 and the threaded locking hole 43, and in conjunction with the terminal ring 45 and the terminal frame 46, the grounding wire 47 and other components are installed. At this time, under the action of the rubber round block 410 and other components, the grounding wire 47 can be squeezed so that the grounding wire 47 can be fixed to one side of the device body 1. At the same time, under the action of the arc plate 41 and the U-shaped frame 42, the grounding wire 47 can be auxiliaryly limited to avoid the grounding wire 47 from getting tangled with the connecting wire 3, thereby preventing it from detaching during the pulling process. By setting up the disassembly and fixing structure 5, the device body 1 can be magnetically fixed to the iron object under the action of the first magnet 53 and the second magnet 56. At the same time, the device body 1 can be fixed to the concrete wall under the action of components such as the circular chuck 59. At this time, the mounting plate 515 needs to be fixed to the wall in advance.

[0027] Going further, such as Figures 2-3 As shown: A grounding wire 47 is snapped into the inside of the terminal frame 46. A U-shaped plate 48 is fixedly connected to one side of the device body 1. A threaded rod 49 is threadedly connected to one side of the U-shaped plate 48. A rubber block 410 is fixedly connected to one end of the threaded rod 49. Under the action of the threaded rod 49, the rubber block 410 can be driven to move, so that the rubber block 410 can be squeezed and fixed with the grounding wire 47, thereby preventing the grounding wire 47 from separating from the terminal frame 46.

[0028] The above solution also has the problem that grounding wire 47 is prone to getting tangled with connecting wire 3, leading to conduction failure or separation when pulled apart. Figure 4 and Figure 5 As shown: In this scheme, an arc-shaped plate 41 is fixedly connected to the bottom of the device body 1, and a U-shaped frame 42 is fixedly connected to one side of the arc-shaped plate 41. Under the action of the arc-shaped plate 41, it can cooperate with the U-shaped frame 42 to limit the grounding wire 47, so that the grounding wire 47 can be limited inside the U-shaped frame 42 with the help of components such as the rubber block 410, thereby avoiding the grounding wire 47 from getting tangled with components such as the connecting wire 3, which would lead to detachment or affect conductivity.

[0029] The above solutions also have the problem that the first magnet 53 and the second magnet 56 cannot be properly fixed when fixed to concrete walls or non-ferrous walls. Figure 4 and Figure 5 As shown, a circular slot 57 is provided on one side of the device body 1. A circular chuck 59 is engaged with the inner wall of the circular slot 57. A rectangular frame 512 is fixedly connected to one side of the circular chuck 59. A rectangular block 513 is engaged with the inner wall of the rectangular frame 512. A first screw hole 58 is provided on the inner wall of the circular slot 57. A second screw hole 510 is provided on one side of the circular chuck 59. A first threaded rod 511 is threadedly connected to the inner walls of the first screw hole 58 and the second screw hole 510. A third screw hole 518 is provided on the top of the rectangular frame 512. A fourth screw hole 519 is provided on the top of the rectangular block 513. The third screw hole 518 and the fourth screw hole 519 are connected together. The inner wall of 19 is threaded with a second threaded clamp rod 54. A connecting rod 514 is fixedly connected to one side of the rectangular clamp block 513. A mounting plate 515 is fixedly connected to one side of the connecting rod 514. A round insertion hole 516 is opened on one side of the mounting plate 515. A bolt 517 is inserted into the inner wall of the round insertion hole 516. Under the action of the connecting rod 514, the mounting plate 515 and the bolt 517 can be matched and thus fixed to the wall. At the same time, under the action of the rectangular clamp block 513 and the rectangular clamp frame 512, the round clamp 59 and the connecting rod 514 can be installed. At this time, the device body 1 can be installed.

[0030] Working principle:

[0031] like Figure 1-5 As shown:

[0032] In use, the grounding wire 47 is snapped and fixed to the terminal frame 46, the magnet snaps the terminal ring 45 to the threaded locking rod 44, and then the threaded locking rod 44 is fixed to the threaded locking hole 43. Then the grounding wire 47 is attached to the arc plate 41 and the U-shaped frame 42. At this time, the threaded rod 49 is rotated so that the rubber block 410 can squeeze and fix the grounding wire 47.

[0033] When it is necessary to install it with an iron object, the first magnet 53 is magnetically attracted and fixed to the round iron block 52, and the second magnet 56 is magnetically attracted and fixed to the external iron object.

[0034] When it is necessary to fix it to a non-ferrous wall, the magnet will pre-fix the mounting plate 515 to the wall through bolts 517 and round insertion holes 516. The magnet will then engage the round chuck 59 with the round slot 57, fix the first threaded rod 511 with the first screw hole 58 and the second screw hole 510, and then fix the rectangular block 513 with the rectangular frame 512. Finally, the second threaded rod 54 will be fixed with the third screw hole 518 and the fourth screw hole 519 to complete the installation.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
