[0009] Further, the hoisting box is located at the included angle between the top surface and the side surface of the carriage body, and the hoisting box is provided with a lateral opening.

[0010] The beneficial effects of the present application are:

[0011] 1、The horizontal plate baffle of the present application is closely attached to the opening bottom surface when the flap is closed, so that the upper surface of the lifting box is completely flush with the top surface of the compartment body, eliminating the convex structure, avoiding the visual obtrusiveness of the traditional welded lifting ring, preventing damage or hooking of foreign matter during transportation, and being more secure and beautiful.

[0012] 2、The lifting ring of the present application is independently installed on the flap through threaded connection, and can be directly disassembled and replaced when damaged; the shaft connection of the flap and the lifting box is also convenient for overall replacement, significantly reducing maintenance cost and time.

[0013] 3、The present application forms a sealed plane when closed, blocking the garbage from contacting the lifting ring, and the lateral opening design of the lifting box can drain water and dirt, preventing the lifting ring from being contaminated by garbage from the source, prolonging the service life of the components and reducing the cleaning needs.

[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0024] For example, Figures 1-4As shown, a garbage truck carriage hoisting structure, comprising a compartment 1, the compartment 1 is provided with a hoisting box 2 at least at the top four corner positions, the upper surface of the hoisting box 2 is flush with the upper surface of the compartment 1, the upper end of the hoisting box 2 is provided with an opening, the opening is rotatably provided with a flap 3, the cross section of the flap 3 is T-shaped, the top of the T-shaped flap 3 is defined as a horizontal plate 301, the horizontal plate 301 extends downward along the middle part to form a vertical plate 302, the flap 3 is provided with an outwardly extending pivot shaft 303 at the connection between the horizontal plate 301 and the vertical plate 302, the hoisting box 2 is provided with a shaft hole for accommodating the pivot shaft 303, the pivot shaft 303 is rotatably connected in the shaft hole, the contour of the horizontal plate 301 is consistent with the opening contour of the hoisting box, the left side of the horizontal plate 301 is provided with a stop edge 304, the stop edge 304 is wider than the horizontal plate 301 and can abut against the bottom surface of the opening, the vertical plate 302 is provided with a lifting ring 4, the lifting ring 4 is perpendicular to the vertical plate 302, the contour of the vertical plate 302 is larger than the contour of the opening, when the flap 3 is rotated by 90°, the vertical plate 302 abuts against the bottom surface of the opening, and the stop edge 304 and the vertical plate 302 limit the rotation of the flap 3.

[0025] In this scheme, in the non-hoisting state, the flap 3 is affected by gravity, the horizontal plate 301 remains horizontal, the stop edge 304 of the horizontal plate 301 abuts against the bottom surface of the opening, the flap 3 is flush with the top surface of the compartment 1, forming a sealed plane without protruding structure, which is beautiful and avoids collision, when the lifting ring 4 is needed, the left side of the horizontal plate 301 is pressed, the right side of the horizontal plate 301 is raised upward, the vertical plate 302 abuts against the bottom surface of the opening by manual rotation, at this time the lifting ring 4 is vertically upward, the lifting hook or lifting rope can be installed, which can be manually rotated without tools, realizing the switching between "sealed in non-working state" and "ready for hoisting" state.

[0026] In practical application, the horizontal plate 301 is provided with a protrusion 305 above the left side of the pivot shaft 303. The protrusion 305 provides a force point for people to press or step on the protrusion 305, which can more conveniently pry the flap 3.

[0027] In practical application, the pivot shaft 303 is located at the left center of the horizontal plate 301, which can reduce the length of the left side of the force arm, make the right side easier to raise in the same action distance, and also can reduce the volume of the hoisting box 2.

[0028] In practical application, the lifting ring 4 is installed on the flap 3 through threaded connection. When the lifting ring 4 is damaged, it can be individually disassembled and replaced without overall maintenance of the hoisting box 2.

[0029] In practical application, the lifting ring 4 is a rotating lifting ring 4. The rotating lifting ring 4 allows the lifting ring 4 to rotate to adapt to the angle of the lifting rope.

[0030] In practical application, the lifting box 2 is located at the corner of the top surface and the side surface of the compartment 1, and the lifting box 2 is provided with a lateral opening 201. Rainwater can be discharged through the lateral opening, so as to avoid water accumulation in the lifting box 2 and corrosion of the lifting box 2, and splashes during operation of the garbage truck can be discharged through the opening, so as to keep the mechanism clean.
