Detailed Implementation

[0027] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0028] Example 1 like Figures 2-5 As shown, a protective panel with a concealed locking structure according to this embodiment includes a panel body 1, an L-shaped locking plate 2, and a connecting ear plate 3. The panel body 1 has a locking edge 11 and a hinge edge 12 arranged at an angle. The connecting ear plate 3 is fixed on the hinge edge 12 and located inside the panel body 1. The connecting ear plate 3 has a hinge hole 31, and the central axis of the hinge hole 31 is arranged parallel to the panel body 1. One end of the L-shaped locking plate 2 is fixed on the locking edge 11 and located inside the panel body 1. The other end of the L-shaped locking plate 2 extends radially towards the periphery of the panel body 1. A first magnetic attractor 21 is fixed on the side wall of the L-shaped locking plate 2 near the other end, or the L-shaped locking plate 2 itself is the first magnetic attractor 21.

[0029] like Figure 2 and Figure 3As shown, in this embodiment, the preferred embodiment regarding the hinge edge 12 is that the panel body 1 has two parallel hinge edges 12, each hinge edge 12 is fixed with a connecting ear plate 3, and the hinge holes 31 on the two connecting ear plates 3 are arranged coaxially. By setting two parallel hinge edges, the hinge stability of the panel body is improved.

[0030] Alternatively, the hinge edge 12 is arranged perpendicular to the locking edge 11, resulting in higher structural stability. The L-shaped locking plate 2 is fixed at the middle position of the locking edge 11, making the locking structure of the entire panel body more stable and reliable.

[0031] like Figure 2 and Figure 3 As shown, in one specific embodiment, the L-shaped locking plate 2 includes a fixed section and a locking section that are integrally and vertically connected. One end of the fixed section is fixed to the locking edge 11 and is arranged perpendicularly to the panel body 1. The locking section is arranged parallel to the panel body 1.

[0032] Specifically, such as Figure 3 As shown, the first magnetic suction component 21 in this embodiment can be a magnet or an iron sheet. That is, the other two sides of the L-shaped locking plate 2 are fixed with magnets or iron sheets by the first bolts 22, or the L-shaped locking plate 2 itself is made of magnets or iron sheets bent.

[0033] The protective panel with a concealed locking structure in this embodiment has an L-shaped locking plate and connecting ear plate located inside the panel body. During assembly and use, they can be hidden inside the protective cover, preventing external exposure and improving aesthetics. This also reduces contact with rainwater and dirt, making it less prone to corrosion and ensuring high locking reliability. The L-shaped locking plate fits snugly and adapts to the second magnetic component on the inner side of the protective cover, ensuring reliable and stable locking.

[0034] Example 2 Based on Embodiment 1, this embodiment provides a preferred arrangement of the locking edge 11 and the hinged edge 12. For example... Figure 2 and Figure 3 As shown, the locking edge 11 extends towards the inner side of the panel body 1 to form a locking protrusion 14, and the hinge edge 12 extends towards the inner side of the panel body 1 to form a hinge protrusion 13. One end of the L-shaped locking plate 2 is fixed to the locking protrusion 14, and the connecting ear plate 3 is fixed to the hinge protrusion 13. By setting the locking protrusion and the hinge protrusion, the first magnetic suction member and the connecting ear plate can be better concealed inward.

[0035] In fact, one optional solution of this embodiment is that the panel body 1 can adopt a rectangular structure, and a raised edge can be provided on the inner side periphery of the panel body 1. The raised edge corresponding to the locking edge 11 is the locking raised edge 14, and the raised edge corresponding to the hinge edge 12 is the hinge raised edge 13.

[0036] Example 3 Based on Embodiment 1 or Embodiment 2, this embodiment also provides a protective cover assembly, such as... Figures 3-5 As shown, the device includes a protective panel with a concealed locking structure as described above, and a protective panel body 4. The protective panel body 4 has an observation hole 41. The inner side of the protective panel body 4 is provided with a hinge shaft 42 and a locking pin 43. The hinge shaft 42 and the locking pin 43 are both located around the observation hole 41. The hinge shaft 42 is hinged in the hinge hole 31. The locking pin 43 is provided with a second magnetic member 44 that magnetically attracts the first magnetic member 21, or the locking pin 43 itself is a second magnetic member 44 that magnetically attracts the first magnetic member 21. When the panel body 1 is closed, the first magnetic member 21 and the second magnetic member 44 come into contact and magnetically attract each other.

[0037] like Figure 4 As shown, in this embodiment, when the panel body 1 opens the observation hole 41, the panel body 1 divides the observation hole 41 into a first hole and a second hole. The first hole is located near the locking pin 43. The height of the second hole is A, and the height of the first hole is B, where A ≥ 2B. By limiting the height dimensions of the two holes, opening and closing are made smoother.

[0038] Specifically, in this embodiment, the second magnetic member 44 can be a magnet or an iron sheet, as long as it can magnetically attract the first magnetic member 21. That is, the other end face of the locking post 43 is fixed with a magnet or an iron sheet by the second bolt 45, or the locking post 43 itself is made of magnet or iron material.

[0039] In this embodiment, the protective cover assembly hides the hinge shaft and locking pin inside the cover body, and sets the L-shaped locking plate and connecting ear plate inside the panel body. Whether the panel body is in the open or closed state, it is hidden inside the cover, reducing contact with rainwater, dirt, etc., and making it less prone to rust.

[0040] Example 4 Based on Embodiment 3, this embodiment provides a preferred installation scheme for the hinge shaft, such as... Figure 3 and Figure 4As shown, a connector is fixed to the inner side of the protective cover body 4. The connector has a limiting groove 54, and the hinge shaft 42 is coaxially fixed in the limiting groove 54. The connector includes a stud 5, a nut 51, a limiting block 52, and a metal plate 53. The middle part of the metal plate 53 is bent to form the limiting groove 54. Limiting holes 56 and connecting holes 55 are opened on the metal plates 53 on both sides of the limiting groove 54. The stud 5 is adapted to pass through the connecting hole 55, and the limiting block 52 is adapted to be inserted into the limiting hole 56. The limiting groove 54 is located between the limiting block 52 and the stud 5. The nut 51 is adapted to be threadedly connected to the stud 5 and fixes the metal plate 53 to the stud 5.

[0041] By setting limit holes, connecting holes, limit blocks and studs, the metal sheet can be first limited by the limit blocks and studs, and then locked and positioned by tightening the studs with nuts, which is convenient for disassembly and assembly.

[0042] Example 5 Based on Embodiment 3 or Embodiment 4, this embodiment also provides an agricultural machine, including an agricultural machine body and the above-mentioned protective cover assembly. The protective cover body 4 is fixed on the agricultural machine body, the locking edge 11 is located above the panel body 1, the hinge edge 12 is located on the left and / or right side of the panel body 1, and the locking post 43 is located above the observation hole 41.

[0043] In this embodiment of the agricultural machinery, the locking structure of the protective cover panel is hidden inside the cover, making the agricultural machinery more aesthetically pleasing, preventing the accumulation of rainwater, dirt, etc., avoiding rust, and extending the service life of the agricultural machinery cover.
