[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] This utility model embodiment provides a sealing plate structure for the hood of construction machinery, which is detachably connected to the frame 100 of the construction machinery (such as a loader).

[0036] like Figures 1-5 As shown, the sealing plate structure for the hood of engineering machinery includes a sealing plate body 1, a plug-in plate 2, and a locking frame 3. The upper part of the sealing plate body 1 is provided with a locking component 11, and the lower part of the sealing plate body 1 is provided with a plug-in hole 121. Both the plug-in plate 2 and the locking frame 3 are mounted on the vehicle frame 100. When the sealing plate body 1 is connected to the vehicle frame 100, the plug-in plate 2 is inserted into the plug-in hole 121, and the locking component 11 can engage and lock with the locking frame 3. When it is necessary to disassemble the sealing plate body 1, after unlocking the locking component 11 and the locking frame 3, simply lift the sealing plate body 1 upwards to pull the plug-in hole 121 out of the plug-in plate 2, thus achieving the disassembly of the sealing plate body 1. Furthermore, when the sealing plate body 1 is connected to the frame 100, the plug plate 2 is inserted into the plug hole 121, and at the same time, the plug plate 2 elastically abuts against the sealing plate body 1, so that the sealing plate body 1 has an elastic force in the direction away from the frame 100, so that the locking assembly 11 and the locking frame 3 can be stably engaged, and the sealing plate body 1 is prevented from shaking.

[0037] The sealing plate structure for the hood of engineering machinery is connected to the insertion hole 121 via the insertion plate 2, and the locking component 11 is locked with the locking frame 3. When the sealing plate body 1 is disassembled, after the locking component 11 and the locking frame 3 are unlocked, the sealing plate body 1 can be lifted directly to disengage the insertion plate 2 from the insertion hole 121, thereby separating the sealing plate body 1 from the frame 100. Disassembly can be achieved without the aid of tools, making engine maintenance inside the hood more convenient. Furthermore, when the insertion plate 2 is inserted into the insertion hole 121, the insertion plate 2 can elastically abut against the sealing plate body 1, which can effectively prevent the sealing plate body 1 from shaking and improve the stability of the connection between the sealing plate body 1 and the frame 100.

[0038] Optionally, such as Figure 3 As shown, the connector plate 2 includes a fixing part 21 and an abutment part 22 that can be inserted into the connector hole 121. The fixing part 21 is connected to the frame 100 by screws. The abutment part 22 includes a ramp 221 and an abutment plate 222. The ramp 221 is disposed on the fixing part 21 and inclined toward the sealing plate body 1. The abutment plate 222 is disposed at the end of the ramp 221 away from the fixing part 21 and elastically abuts against the sealing plate body 1. In this structure, when the abutment plate 222 abuts against the sealing plate body 1, the ramp 221 provides an elastic abutment force toward the sealing plate body 1.

[0039] In this embodiment, the fixing part 21 includes a fixing horizontal plate 211 and a supporting vertical plate 212 that are perpendicularly distributed to each other. The fixing horizontal plate 211 is connected to the frame 100 by screws, and the inclined plate 221 is disposed on the supporting vertical plate 212. The sealing plate body 1 can be supported on the supporting vertical plate 212.

[0040] Optionally, such as Figure 4 As shown, the locking frame 3 includes a locking support 31 and a locking plate 32. The locking support 31 is mounted on the frame 100 by screws, and the locking plate 32 is rotatably connected to the locking support 31. The locking plate 32 is used to lock with the locking assembly 11. When the locking plate 32 and the locking assembly 11 are unlocked, the locking plate 32 can rotate relative to the locking support 31 toward the frame 100 so that the locking plate 32 can be supported on the frame 100. This ensures that the locking frame 3 does not interfere with maintenance personnel during engine maintenance and avoids the locking frame 3 occupying upper space.

[0041] Specifically, the locking plate 32 includes a rotating support plate 321, a connecting plate 322, and a locking angle plate 323. The connecting plate 322 is rotatably connected to the locking support 31 via a rotating shaft. The lower end of the connecting plate 322 is provided with a socket. The rotating support plate 321 is inserted into the socket and welded to the connecting plate 322. One side plate of the locking angle plate 323 is connected to the upper part of the connecting plate 322. The other side plate of the locking angle plate 323 is provided with a locking hole 3231. The locking assembly 11 can lock with the locking hole 3231. This structure makes the connection between the locking plate 32 and the locking support 31 reasonable, and the other side plate of the locking angle plate 323 can remain parallel to the sealing plate body 1, so as to make the locking connection more convenient.

[0042] Optionally, such as Figures 1-2 Combined Figure 5 As shown, the locking assembly 11 includes a pin 111 and a locking plate 112. The pin 111 is connected to the sealing plate body 1 and is perpendicular to the sealing plate body 1. The locking plate 112 is rotatably connected to the pin 111, allowing the locking plate 112 to rotate relative to the pin 111, thus enabling the locking plate 112 to switch between a locked state and an unlocked state. When locking is required, the pin 111 can be inserted into the locking hole 3231, and the locking plate 112 and the pin 111 are cross-distributed, so that the locking plate 112 can abut against the other side plate of the locking corner plate 323 and cannot disengage from the locking hole 3231, thus placing the locking plate 112 in the locked state. When unlocking is required, the locking plate 112 is rotated so that the locking plate 112 and the pin 111 are arranged in a straight line, placing the locking plate 112 in the unlocked state, allowing the locking plate 112 to disengage from the locking hole 3231, thus unlocking.

[0043] Furthermore, the locking plate 112 is provided with an elongated hole 1121 extending along its length direction. The first end of the elongated hole 1121 along its length direction is located in the middle of the locking plate 112, and the second end of the elongated hole 1121 along its length direction is located at one end of the locking plate 112. The end of the insertion pin 111 away from the sealing plate body 1 is provided with a notch, and the locking plate 112 is disposed in the notch. The insertion pin 111 is provided with a pin arranged radially thereon, and the pin passes through the elongated hole 1121. The locking plate 112 can move and rotate relative to the pin through the elongated hole 1121. When the locking plate 112 is in the locked state, the pin is located at the first end in the elongated hole 1121, and the locking plate 112 can rotate to be distributed crosswise with the insertion pin 111 to achieve locking. When the locking plate 112 is in the unlocked state, the pin is located at the second end in the elongated hole 1121, and the locking plate 112 can rotate to be distributed in a straight line with the insertion pin 111 to facilitate unlocking.

[0044] To ensure that the locking plate 112 can fit tightly against the other side plate of the locking angle plate 323 when locked, the elongated hole 1121 is designed as an inclined hole. When locking is required, the locking plate 112 moves downward, and the pin switches from the second end to the first end of the inclined hole. During this process, the inclined hole allows the locking plate 112 to move towards the other side plate of the locking angle plate 323, so that the locking plate 112 abuts against the other side plate of the locking angle plate 323, making the lock secure. It can be understood that when the locking plate 112 is in the locked state, the inclined hole gradually tilts towards the other side plate of the locking angle plate 323 from top to bottom.

[0045] Optionally, the elongated hole 1121 is provided with a wavy shape on one side along the length of the clamping plate 112. The wavy side can obstruct the pin shaft to prevent the clamping plate 112 from becoming loose due to vibrations generated by the engineering machinery during walking or operation.

[0046] Optionally, a plug-in corner plate 12 is provided at the lower part of the sealing plate body 1. The vertical plate of the plug-in corner plate 12 is welded to the sealing plate body 1. The horizontal plate of the plug-in corner plate 12 is provided with a plug-in hole 121. The inclined plate 221 of the plug-in plate 2 is inserted into the plug-in hole 121. The supporting vertical plate 212 of the plug-in plate 2 supports the horizontal plate of the plug-in corner plate 12 to form a stable plug-in connection.

[0047] In this embodiment, the plug hole 121 is a square hole. When the plug plate 2 is inserted into the square hole, the plug plate 2 has a certain amount of room to move, so as to facilitate disassembly and assembly.

[0048] Optionally, two connector plates 2 are provided, spaced apart on the frame 100. The lower part of the sealing plate body 1 has two connector corner plates 12, each corresponding to a connector plate 2. The horizontal plates of the connector corner plates 12 have connector holes 121, and the two connector plates 2 are respectively inserted into the connector holes 121 of the two connector corner plates 12. By providing two connector plates 2, the connection between the sealing plate body 1 and the frame 100 is made more stable.

[0049] This utility model embodiment also provides an engineering machinery, including the above-mentioned sealing plate structure for the engineering machinery hood, which makes engine maintenance inside the hood more convenient.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
