Abstract
Description
Technical Field
[0001] This invention belongs to the field of mechanical equipment technology, and particularly relates to a housing locking mechanism, an engineering vehicle, and a locking method. Background Technology
[0002] In the process of urban waste collection and transportation, waste transfer equipment plays a crucial role. Typically, small garbage trucks transport waste to transfer stations, and then medium to large vehicles transport the waste from the transfer equipment to larger waste treatment plants for processing. Underground garbage containers are a typical example of waste transfer equipment, relying on medium-sized vehicles to transport waste to large waste treatment plants and using vehicle lifting for unloading.
[0003] Initially, underground garbage bins were placed directly in the cargo compartment of transport vehicles. The compartment had horizontal limiting structures on both sides and the front and rear ends to prevent the underground garbage bins from moving horizontally. However, there was a lack of vertical limiting structures, which caused the underground garbage bins to tend to separate from the cargo compartment during transport and unloading, resulting in poor safety.
[0004] The locking method mentioned in the related technology is as follows: A frame is added to the bottom of the carriage, and a rotary lock is installed on the frame. The rotary lock is vertical. By aligning the bottom locking hole 211 of the corner piece on the box with the lock head of the rotary lock and inserting it vertically downwards, the lock head can be limited in the inner cavity of the corner piece 21 by rotating the rotary lock. The structure of the box 2 is as follows. Figure 1 As shown, this method achieves the limiting and locking of the container. However, because the rotary lock is set vertically, the added frame thickness is large, increasing the overall height of the vehicle. When transferring garbage containers, the distance between the garbage container and the top of the transfer station's gate is too close, posing a risk of interference. Summary of the Invention
[0005] To address the aforementioned problems in the prior art, this invention provides a housing locking mechanism, an engineering vehicle, and a locking method.

[0024] This embodiment provides a housing locking mechanism, such as Figure 2 , Figure 3 and Figure 4 As shown, it includes: Base 1, used to place box 2; The locking hook 7 is rotatably connected to the base 1 and is used to lock the box 2; The driving component 3 has its fixed end rotatably connected to the base 1; Linkage mechanism, including: The first rod 4 has its first end 41 hinged to the base 1 and its second end 42 hinged to the driving end of the driving member 3. The second rod 5 has its first end 51 hinged to the third end 43 of the first rod 4; The third rod 6 is connected to the locking hook 7, and its first end 61 is hinged to the base 1, and its second end 62 is hinged to the second end 52 of the second rod 5. When the locking hook 7 locks the box 2, the hinge point 41 between the first rod 4 and the base 1, the hinge point 43 between the first rod 4 and the second rod 5, and the hinge point 62 between the second rod 5 and the third rod 6 are collinear.
[0025] Locking method: such as Figure 2 and Figure 3 The driving component 3 drives the second end 42 of the first rod 4 to move. The first rod 4 rotates away from the driving component 3 along the hinge point between its first end 41 and the base 1, which drives the second end 62 of the second rod 5 and the third rod 6 to move. The third rod 6 rotates with its first end 61 and the hinge point between the base 1 as the axis, which synchronously drives the locking hook 7, which is fixed relative to the third rod 6, to rotate. The locking hook 7 moves towards the box 2. By inserting the locking hook 7 into the side wall of the box 2 or the side hole of the corner piece 21 of the box 2, the box 2 can be locked.
[0026] In this invention, the housing 2 is placed directly on the base 1, and the locking device is also directly arranged on the base 1, avoiding the increase in height caused by setting a frame on the housing 2 and the base 1, resulting in a compact structure; furthermore, in this invention, when the locking hook 7 locks the housing 2, the hinge points of the first rod 4 and the base 1, the hinge points of the first rod 4 and the second rod 5, and the hinge points of the second rod 5 and the third rod 6 are collinear (e.g., Figure 4 This achieves mechanical self-locking of the locking device.
[0027] In one possible embodiment, an engineering vehicle is also provided, wherein the housing 2 is provided with a lock hole 211, and the lock hook 7 can be inserted into or removed from the lock hole 211 by rotation.

The mounting base 81 and the limiting base 82 ensure the stability of the transmission of the connecting drive shaft 8 and the stability of the rotation of the locking hook 7. Bearings can also be provided on the mounting base 81 and the limiting base 82 as needed to further reduce rotational resistance.
[0033] The hinge point of the third rod 6 and the base 1 is collinear with the connecting drive shaft 8.

By extending or retracting the telescopic bar, the first rod 4 can be rotated, thereby causing the locking hook 7 to lock the box.
[0035] In one possible embodiment, an engineering vehicle is also provided, such as Figure 5 and Figure 6 As shown, the aforementioned box locking mechanism is arranged on it.
[0036] In one possible embodiment, the engineering vehicle includes a garbage container transfer vehicle, and the container body 2 includes a garbage transfer container. The design of this application minimizes the overall vertical height while locking the container body 2, facilitating transfer.
