DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the implementation of the present invention will be clearly and completely described below in conjunction with the drawings in the implementation of the present invention. Obviously, the described implementation is only a part of the implementation of the present invention, not all of the implementations. Based on the implementation of the present invention, all other implementations obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0027] In the description of the present invention, it should be understood that the terms "top", "bottom", "up", "down", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0028] The conventional ventilation plate is an integrated structure, which expands when heated, resulting in stress concentration and severe deformation. The ventilation plate installation structure of the utility model is intended to solve this technical problem.

[0029] Reference Figures 1 to 7 As shown, a moisture meter ventilation plate mounting structure in one embodiment of the utility model comprises a shell 1, a ventilation plate 2, a first mounting plate 3 and a second mounting plate 4. The shell 1 is provided with a ventilation hole 11 penetrating the shell 1. The ventilation plate 2, the first mounting plate 3 and the second mounting plate 4 are all mounted on the shell 1. The ventilation plate 2 covers the ventilation hole 11, and the first mounting plate 3 and the second mounting plate 4 are respectively abutted against two sides of the ventilation plate 2.

[0030] According to the above structural design, the traditional one-piece ventilation plate is divided into a ventilation plate 2, a first mounting plate 3 and a second mounting plate 4 that are spliced ​​and assembled. During assembly, the first mounting plate 3 can be installed on the shell 1 first, and then the ventilation plate 2 can be installed so that it abuts against the first mounting plate 3. Finally, the second mounting plate 4 can be installed and abutted against the ventilation plate 2. The ventilation plate 2 is limited and fixed by the first mounting plate 3 and the second mounting plate 4.

[0031] When the moisture meter is actually working, the ventilation plate 2, the first mounting plate 3 and the second mounting plate 4 expand and deform due to heat. The installation gap between the three can provide expansion and deformation space to avoid local stress concentration caused by mutual squeezing after expansion and prevent serious deformation of the three.

[0032] In addition, when the ventilation plate 2, the first mounting plate 3 and the second mounting plate 4 are partially damaged, only the damaged parts can be replaced, which can save maintenance costs and maintenance time.

[0033] In order to further limit the ventilation plate 2, the first mounting plate 3 and the second mounting plate 4 to prevent the ventilation plate 2, the first mounting plate 3 and the second mounting plate 4 from loosening when the moisture meter is working, specifically, refer to Figure 5 and Figure 6 As shown, a mounting groove 12 is provided on the shell 1, and the ventilation plate 2, the first mounting plate 3 and the second mounting plate 4 are all installed in the mounting groove 12, and the lateral ends are close to the groove wall of the mounting groove 12 to limit the movement of the ventilation plate 2, the first mounting plate 3 and the second mounting plate 4 through the groove wall of the mounting groove 12.

[0034] In one embodiment, the first mounting plate 3 can be engaged with the housing 1 by a snap-fitting method. Figure 2 , Figure 3 and Figure 6 As shown, the bottom wall of the mounting groove 12 is provided with at least one slot 13 penetrating the bottom wall (i.e., the shell wall of the shell 1), and the bottom of the first mounting plate 3 is provided with snap-fitting parts corresponding to the number of the slots 13. In the assembled state, the snap-fitting parts are snap-fitted with the slots 13.

[0036] After the first clamping member 35 is inserted into the clamping slot 13, the second extension portion 352 thereof can play a role similar to a hook, hooking the shell wall from the bottom of the shell 1, and restricting the first mounting plate 3 from moving upward and separating from the shell 1. As for the first extension portion 351, it can abut against the side wall of the clamping slot 13 or maintain a certain distance therefrom.

[0037] In order to further improve the connection strength and stability between the first mounting plate 3 and the housing 1, refer to Figure 3 and Figure 7 As shown, the clamping member includes a second clamping member 36 which is arranged on the side of the first mounting plate 3 away from the ventilation plate 2. The second clamping member 36 is bent from the end of the first mounting plate 3 toward the side away from the ventilation plate 2. The slot 13 corresponding to the second clamping member 36 passes through the lateral slot wall of the mounting slot 12. The second clamping member 36 at least partially extends into the slot 13 and abuts against the side wall of the mounting slot 12 at the top of the slot 13 to limit the first mounting plate 3 from moving upward and out of the mounting slot 12.

[0038] In addition, refer to Figure 3As shown, in order to further limit the movement of the first mounting plate 3 in the mounting groove 12 , the side of the first mounting plate 3 away from the ventilation plate 2 abuts against the side wall of the mounting groove 12 .

The first protrusion 21 extends into the first receiving groove 34 to limit the ventilation plate 2 from moving upward and leaving the mounting groove 12. The second protrusion 22 abuts against the end of the ventilation plate 2 to limit the ventilation plate 2 from moving in the direction close to the first mounting plate 3, thereby stabilizing the position of the ventilation plate 2.

[0040] The first receiving groove 34 may extend to the bottom of the first mounting plate 3 , and its specific size and structure may be set according to actual conditions.

[0041] In addition, in order to reduce the thickness and weight of the first mounting plate 3 and improve the heat dissipation efficiency of the housing 1 at the first mounting plate 3, the first mounting plate 3 can be composed of a first top plate 31, a first side plate 32 and a second side plate 33 arranged on opposite sides of the first top plate 31 and extending downward, and a plate body arranged on both sides of the first side plate 32 and the second side plate 33.

Figure 6 and Figure 7 As shown, the shell 1 is provided with at least one mounting hole 14 penetrating the shell 1, and the bottom of the second mounting plate 4 is provided with latches 44 corresponding to the number of mounting holes 14, and the latches 44 are provided with threaded holes in the axial direction. In the assembled state, the latches 44 are inserted into the mounting holes 14.

[0044] During specific assembly, after the latch 44 is inserted into the mounting hole 14 , a bolt is screwed into the threaded hole from the bottom of the latch 44 , and the head of the bolt gradually approaches the bottom wall of the shell 1 until it abuts against the bottom wall of the shell 1 , thereby fixing the latch 44 in the mounting hole 14 .

[0045] Reference Figure 4 and Figure 7As shown, the joining method of the second mounting plate 4 and the ventilation plate 2 can refer to the joining method of the first mounting plate 3 and the ventilation plate 2 .

[0046] Specifically, a second receiving groove 43 is provided on the side of the second mounting plate 4 close to the ventilation plate 2, and a third protrusion 23 protruding toward the second mounting plate 4 and a fourth protrusion 24 protruding toward the top are provided on the side of the ventilation plate 2 close to the second mounting plate 4. The third protrusion 23 extends into the second receiving groove 43 to limit the ventilation plate 2 from moving upward and leaving the mounting groove 12. The fourth protrusion 24 abuts against the end of the second mounting plate 4 to limit the ventilation plate 2 from moving in the direction close to the second mounting plate 4, thereby stabilizing the position of the ventilation plate 2.

[0047] In order to reduce the thickness and weight of the second mounting plate 4 and improve the heat dissipation efficiency of the shell 1 at the second mounting plate 4, the second mounting plate 4 can be composed of a second top plate 41, a third side plate 42 extending downward from one side of the second top plate 41, and a plate body located on both sides and the opposite side of the third side plate 42, wherein the third side plate 42 is arranged close to the ventilation plate 2, and the second receiving groove 43 is arranged on the third side plate 42.

[0048] The second receiving groove 43 may extend to the bottom of the third side plate 42 and the side of the third side plate 42 away from the ventilation plate 2 , and its specific size and structure may be set according to actual conditions.
