[0023] The technical scheme of the utility model will be further described below in combination with the drawings of the embodiments of the utility model. The utility model is not limited to the following specific embodiments. It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict.
[0024] As shown in Figures 1 to 5 A precise positioning and locking structure of a waterproof surface cover 200 and a cabinet of an IP65 off-grid inverter, comprising: a cabinet 100, a surface cover 200, a first positioning mechanism, a second positioning mechanism and a locking mechanism; a cavity is formed in the interior of the cabinet 100, the first positioning mechanism is partially arranged on one side wall of the cabinet 100 and partially arranged on the surface cover 200, the second positioning mechanism is partially arranged on another side wall of the cabinet 100 and partially arranged on the surface cover 200; the surface cover 200 movably covers the cavity, and the locking mechanism is used for locking the cabinet 100 and the surface cover 200.
[0025] Specifically, the box 100 is provided with a first mounting block 110 on one side wall and a second mounting block 120 on the other side wall, and the first mounting block 110 is correspondingly arranged with the second mounting block 120. The first positioning mechanism comprises a first positioning pin 310 and a first sleeve 320, the first positioning pin 310 is arranged on the first mounting block 110, the first sleeve 320 is arranged on the face cover 200, and the first positioning pin 310 is movably inserted into the first sleeve 320. The second positioning mechanism comprises a second positioning pin 410 and a second sleeve 420, the second positioning pin 410 is arranged on the second mounting block 120, the second sleeve 420 is arranged on the face cover 200, and the second positioning pin 410 is movably inserted into the second sleeve 420. The first positioning pin 310, the first sleeve 320, the second positioning pin 410 and the second sleeve 420 are all chamfered 800, which facilitates the insertion of the first positioning pin 310 into the first sleeve 320 and the insertion of the second positioning pin 410 into the second sleeve 420. The first positioning pin 310 and the second positioning pin 410 are both provided with waterproof material 700, the waterproof material 700 on the first positioning pin 310 abuts against the first sleeve 320, and the waterproof material 700 on the second positioning pin 410 abuts against the second sleeve 420. Further, the waterproof material 700 is made of EPDM plastic material.
[0026] In one embodiment, the first mounting block 110 is provided with a plurality of first fixing holes, the face cover 200 is provided with a plurality of first connecting holes 201, and each first fixing hole is in movable communication with a first connecting hole 201. The second mounting block 120 is provided with a plurality of second fixing holes, and the face cover 200 is provided with a plurality of second connecting holes 202, each second fixing hole being in movable communication with a second connecting hole 202. The locking mechanism comprises a plurality of first bolts 510 and a plurality of second bolts 520, each first bolt 510 movably penetrating a first connecting hole 201 and a first fixing hole, each second bolt 520 movably penetrating a second connecting hole 202 and a second fixing hole, and the ends of the plurality of first bolts 510 and the plurality of second bolts 520 are provided with bosses 600, each boss 600 blocking one side of a first connecting hole 201 or one side of a second connecting hole 202.
[0027] That is, the cavity is used to install the corresponding electrical components, and after installation, the cover 200 needs to be covered on the entire box 100. Since the first positioning mechanism and the second positioning mechanism are both precisely inserted structures, and the waterproof material 700 is arranged on the first positioning pin 310 and the second positioning pin 410, the EPDM plastic material with lower cost is used for waterproof treatment, which can quickly position and install while increasing the waterproof function, and uses lower-cost raw materials to save the overall production cost. Further, since the first positioning pin 310, the first sleeve 320, the second positioning pin 410, and the second sleeve 420 are all chamfered 800, they can guide the first positioning pin 310 to be more conveniently inserted into the first sleeve 320 and the second positioning pin 410 to be more conveniently inserted into the second sleeve 420. It is worth mentioning that since the first positioning pin 310 corresponds to the first sleeve 320, and the second positioning pin 410 corresponds to the second sleeve 420, that is, the first positioning pin 310 and the second positioning pin 410 are misaligned, therefore, when installing the cover 200, if the installation direction of the cover 200 is wrong, the first positioning pin 310 and the second sleeve 420 are not in the same position at this time, and at the same time, the second positioning pin 410 and the first sleeve 320 are also not in the same position, that is, the first positioning pin 310 cannot be inserted into the second sleeve 420, and the second positioning pin 410 cannot be inserted into the first sleeve 320. Therefore, through this design, it can prevent the cover 200 from being reversed and locked during installation.
[0028] Further, after the first positioning mechanism and the second positioning mechanism are both fixed, a first bolt 510 is inserted into each first connecting hole 201 and a first fixed hole connected thereto, at this time, the boss 600 on the first bolt 510 will block the first connecting hole 201, and then a nut is used for fixing on the other side. Similarly, a second bolt 520 is inserted into each second connecting hole 202 and a second fixed hole connected thereto, at this time, the boss 600 on the second bolt 520 will block the second connecting hole 202, and then a nut is used for fixing on the other side. That is, since the boss 600 is arranged, the first bolt 510 or the second bolt 520 will not be directly visible on one side of the cover 200, which can make the whole more beautiful. The box 100 and the cover 200 are locked by the locking mechanism, which improves the reliability and stability of the product.
[0029] In summary, the above embodiments are not limiting embodiments of the present application. Any modification or equivalent deformation made by those skilled in the art on the basis of the essential content of the present application is within the technical scope of the present application.
