Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] Please refer to Figs. 1-4 In the embodiments of the utility model, the wire joint structure of the environmental monitoring data transmission device comprises a plug assembly 1 and a socket assembly 2. The plug assembly 1 is composed of an aviation plug 101, an anti-skid part 102 and an annular top seat 103. The anti-skid part 102 and the annular top seat 103 are fixed to the outer side of the aviation plug 101, and the annular top seat 103 is distributed on the top of the anti-skid part 102. The socket assembly 2 is composed of an aviation socket 201, a fixed hexagonal block 202 and a fastening nut 203. The fixed hexagonal block 202 is fixed to the middle part of the outer side of the aviation socket 201, and the fastening nut 203 is threadedly connected to the top outer side of the aviation socket 201. A quick mounting assembly 3 is arranged between the plug assembly 1 and the socket assembly 2. The quick mounting assembly 3 comprises a butt joint unit and a self-locking unit.

[0027] The butt joint unit is used to realize the quick butt joint of the plug assembly 1 and the socket assembly 2 in a narrow space.

[0028] When the plug assembly 1 and the socket assembly 2 are connected, the self-locking unit is used to lock the connecting unit, so as to ensure the stability of the connection between the plug assembly 1 and the socket assembly 2.

[0029] The connecting unit comprises a fixed side plate 301, a linkage gear 302, a rotating handle 303, a toothed arm 305, and a limiting arm 306.

[0030] The fixed side plate 301 is symmetrically fixed to the lower surface of the fixed hexagonal block 202 with the aviation socket 201 as the center. The linkage gear 302 is attached to one side surface of the fixed side plate 301 close to the aviation socket 201. The rotating handle 303 is attached to one side surface of the fixed side plate 301 away from the aviation socket 201, and the rotating handle 303 is fixedly connected with the center of the linkage gear 302 through a rotating shaft penetrating the fixed side plate 301.

[0031] The toothed arm 305 and the limiting arm 306 are provided in two groups. The two toothed arms 305 and limiting arms 306 are symmetrically fixed to the upper surface of the annular top seat 103 with the aviation plug 101 as the center. The toothed arm 305 and the limiting arm 306 are symmetrically distributed with the linkage gear 302 as the center. When the plug assembly 1 and the socket assembly 2 are connected to each other, the toothed arm 305 is engaged with the linkage gear 302, and the end surface of the limiting arm 306 is attached to the end surface of the linkage gear 302.

[0032] After the toothed arm 305 and the linkage gear 302 are in contact and engaged, the linkage gear 302 is pulled upward to the vertical state, so as to move the plug assembly 1 upward relative to the socket assembly 2 to achieve complete insertion of the plug assembly 1 and the socket assembly 2.

[0033] In this embodiment, the operation steps of the wire connector in use are as follows:

[0034] First, the socket assembly 2 is installed in the environmental monitoring equipment case. At this time, the nut 203 is removed, and then the data line of the processor inside the environmental monitoring equipment case is sequentially threaded through the nut 203, the mounting hole opened on the environmental monitoring equipment case, and then connected with the wiring end of the aviation socket 201. Then, the upper end threaded part of the aviation socket 201 is threaded through the mounting hole, and then the nut 203 is threadedly connected with the upper end threaded part of the aviation socket 201 and tightened to complete the fixation of the socket assembly 2. Then, the data cable of the environmental monitoring equipment (such as a gas analyzer, a particulate matter monitor, a water quality monitor, etc.) is connected with the wiring end of the aviation plug 101 (it should be noted that the connection structure of the aviation plug 101, the aviation socket 201, and the data cable is a conventional structure of existing aviation plug technology, which will not be described here).

[0035] After the completion of the data cable and the aviation plug 101, the aviation socket 201 is connected, the aviation plug 101, the aviation socket 201 is docked, in the process of aligning the aviation plug 101 with the aviation socket 201 and inserting upward, the tooth arm 305 will contact and engage with the linkage gear 302 (it should be noted that: the aviation plug 101, the aviation socket 201 is provided with a foolproof structure, which can ensure that the tooth arm 305 and the linkage gear 302 are corresponding in position), the tooth arm 305 will drive the linkage gear 302 to rotate, the linkage gear 302 drives the rotating handle 303 to rotate, and the rotating handle 303 rotates upward from the vertical downward state (it should be noted that: in the environment monitoring equipment case, the installation of the aviation socket 201 is downward, that is, the rotating handle 303 maintains the vertical downward state under its own gravity);

[0036] In the process of inserting the aviation plug 101 upward, the friction between the aviation plug 101 and the aviation socket 201 becomes larger and larger, and it is not easy to directly push the aviation plug 101 to the fully inserted state, at this time, the rotating handle 303 can be pulled to make the rotating handle 303 rotate to the vertical state and drive the linkage gear 302 to rotate, and the linkage gear 302 drives the tooth arm 305 and the plug assembly 1 to move upward as a whole, realizing the complete docking of the aviation plug 101 and the aviation socket 201;

[0037] Through the cooperation of the above multiple parts, the convenient disassembly and assembly of the aviation plug 101 and the aviation socket 201 can be realized, compared with the traditional rotating threaded connection structure, no multi-turn operation is needed in the disassembly and assembly process, not only the disassembly and assembly efficiency is faster, but also it can adapt to the narrow space inside the environment monitoring equipment case (it should be noted that: the rotating area of the rotating handle 303 is towards the direction of the cover of the environment monitoring equipment case, which can provide enough rotating space for the rotating handle 303).

[0038] Please refer to Figs. 1-4 , the self-locking unit includes a locking slot 304, a 7-shaped hook 307, and an inclined elastic sheet 308;

[0039] The locking slot 304 is opened on one side of the rotating handle 303 and located at the rotating center part of the rotating handle 303;

[0040] The 7-shaped hook 307 is distributed on one side of the middle of the tooth arm 305 and the limiting arm 306, and the inclined elastic sheet 308 is fixed in the middle of the tooth arm 305 and the limiting arm 306 and fixedly connected with the side surface of the 7-shaped hook 307. When the rotating handle 303 is vertically upward, the top bending part of the 7-shaped hook 307 is clamped into the inside of the locking slot 304 to limit the rotation of the rotating handle 303;

[0041] The bottom end of the rotating position of the rotating handle 303 is arc-shaped structure, and the upper surface of the top bent part of the 7-shaped clamping hook 307 is inclined surface structure.

[0042] The annular top seat 103 is formed with a gap groove at the position corresponding to the 7-shaped clamping hook 307, and the bottom end of the 7-shaped clamping hook 307 is flush with the lower surface of the annular top seat 103 in horizontal height.

[0043] In the embodiment, during the upward insertion of the aviation plug 101, after the tooth arm 305 contacts the linkage gear 302 and moves upward by a distance, the top inclined surface of the 7-shaped clamping hook 307 contacts and extrudes the arc surface of the rotating handle 303, the extrusion force can make the inclined elastic sheet 308 deform outward, and then the top bent part of the 7-shaped clamping hook 307 moves to fit the side surface of the rotating handle 303, the 7-shaped clamping hook 307 can continue to move upward and will not interfere with the upward movement of the aviation plug 101.

[0044] When the rotating handle 303 is completely rotated to the vertical upward state, the locking clamping groove 304 is in a horizontal state, and at this time, the top bent part of the 7-shaped clamping hook 307 is aligned with the locking clamping groove 304, the inclined elastic sheet 308 resets and drives the top bent part of the 7-shaped clamping hook 307 to be clamped into the inside of the locking clamping groove 304, so that the rotating handle 303 cannot be rotated, thereby ensuring the stable butt joint of the plug assembly 1 and the socket assembly 2.

[0045] When disassembly is needed, the bottom end of the two 7-shaped clamping hooks 307 is manually pressed to make the top thereof turn outward and away from the inside of the locking clamping groove 304, and then the plug assembly 1 is pulled downward.

[0046] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
