DETAILED DESCRIPTION

[0039] The following is combined with Figure 1-6 This application is described in further detail.

[0040] An embodiment of the present application discloses a rear door locking device for an integrated garbage compression device.

[0041] Example 1

[0042] Reference Figure 1, a rear door locking device of an integrated garbage compression equipment includes a first fixing pin 1 welded and fixed on both sides of the cover plate, and a second fixing pin 2 welded and fixed on both sides of the cover plate. In this application, two first fixing pins 1 and second fixing pins 2 are provided; a support base 31 is fixed to the side wall of the carriage by bolts, and the door locking device also includes a first hook claw 3 and a second hook claw 4 connected to the side wall of the support base 31 by a rotating shaft, the first hook claw 3 is located at a position close to the first fixing pin 1, and the second hook claw 4 is located at a position close to the second fixing pin 2. During the rotation of the first hook claw 3 and the second hook claw 4, the first hook claw 3 can be hooked on the first fixing pin 1, and the second hook claw 4 can be hooked on the second fixing pin 2. The setting of the first hook claw 3 and the second hook claw 4 plays a limiting role on the cover plate, so that the cover plate is sealed on the side wall of the carriage, avoiding the possibility of garbage leakage in the carriage.

[0043] Reference Figure 1 A first driving member 6 for driving the first hook 3 to rotate is provided on the side wall of the cover plate. In this application, the first driving member 6 is preferably an oil cylinder. A plurality of supports 32 are welded and fixed on the side wall of the cover plate. The cylinder body of the first driving member 6 is hinged to the side wall of the support 32. The piston rod of the first driving member 6 is hinged to the end of the first hook 3 away from the first fixed pin 1 through a connecting rod. When the first driving member 6 is started, the piston rod of the first driving member 6 slides, thereby driving the first hook 3 to rotate, making it easier to hang the first hook 3 on the first fixed pin 1.

[0044] Reference Figure 1 A second driving member 7 for driving the second hook 4 to rotate is provided on the side wall of the cover plate. In this application, the second driving member 7 is preferably a cylinder. The cylinder body of the second driving member 7 is hinged to the side wall of the support 32, and the piston rod of the second driving member 7 is hinged to the end of the second hook 4 through a connecting rod. When the second driving member 7 is started, the piston rod of the second driving member 7 slides, driving the second hook 4 to rotate, so as to facilitate the second hook 4 to be hung on the second fixing pin 2.

[0045] Reference Figure 1 The sliding direction of the piston rod of the first driving member 6 is set at an angle to the length direction of the first claw 3. Since the connection part between the piston rod of the first driving member 6 and the first claw 3 is different from the rotating shaft of the first claw 3, it is convenient for the first driving member 6 to apply force, and when the first claw 3 is hung on the first fixing pin 1, the first driving member 6 and the first claw 3 form an angle support, thereby improving the stability of the first claw 3 and the first fixing pin 1; the sliding direction of the piston rod of the second driving member 7 is set at an angle to the length direction of the second claw 4, and the connection part between the piston rod of the second driving member 7 and the second claw 4 is different from the rotating shaft of the second claw 4, which makes it easier for the second driving member 7 to drive the second claw 4 to rotate, and the second driving member 7 supports the second claw 4, thereby improving the stability of the connection between the second claw 4 and the second fixing pin 2.

[0046] Reference Figure 1 and Figure 2 When the locking pin 10 is rotated, the support rod 9 is connected to the outer wall of the first hook 3 and the second hook 4, and the support rod 9 is connected to the second hook 4 by the screw thread.

[0047] Reference Figure 3 A mounting rod 33 is fixed to the bottom wall of the carriage by bolts. The rear door locking device also includes a bottom lock hook 11 rotatably connected to the outer wall of the mounting rod 33, a fixing sleeve 13 fixed to the bottom wall of the cover plate by bolts, and a lock hook shaft 12 plugged and fixed to the bottom lock hook 11 and the fixing sleeve 13. When the cover plate is covered on the carriage, the bottom lock hook 11 and the fixing sleeve 13 are fixed together by the lock hook shaft 12 to limit the cover plate and reduce the gap between the cover plate and the carriage, thereby reducing the possibility of garbage leakage in the carriage and reducing secondary pollution to the environment.

[0048] In the first embodiment of the present application, the implementation principle of the rear door locking device of an integrated garbage compression equipment is as follows: after the garbage is loaded into the vehicle compartment, the first driving member 6 is started, and the first driving member 6 drives the end of the first hook 3 to rotate toward the outer wall of the first fixed pin 1, and the first hook 3 is hooked on the first fixed pin 1, and the second driving member 7 is started, and the second driving member 7 drives the end of the second hook 4 to rotate toward the outer wall of the second fixed pin 2, and the second hook 4 is hooked on the second fixed pin 2, and the locking pin 10 is rotated, and the locking pin 10 drives the support rod 9 to slide, so that the relative position of the support rod 9 and the locking pin 10 changes, so as to better support the first hook 3 and the second hook 4, thereby making the connection between the first hook 3 and the first fixed pin 1 more stable, and making the connection between the second hook 4 and the second fixed pin 2 more stable, better defining the position of the cover plate, and reducing the possibility of leakage between the cover plate and the vehicle compartment.

[0049] Example 2

[0050] The difference between the second embodiment and the first embodiment is that: Figure 4A guide groove 15 is provided on the side wall of the cover plate, and an anti-funnel 14 is slidably connected to the side wall of the cover plate. A power part 17 for driving the anti-funnel 14 to slide is provided on the side wall of the cover plate. In this application, the power part 17 is preferably a cylinder. The cylinder body of the power part 17 is hinged to the side wall of the cover plate through a mounting block, and the piston rod of the power part 17 is hinged to the outer wall of the anti-funnel 14 through a connecting rod. When the power part 17 is opened, the piston rod of the power part 17 slides, and the anti-funnel 14 slides under the guidance of the guide groove 15.

[0051] Reference Figure 4 In this application, the guide groove 15 consists of a vertical section and an inclined section. The vertical section of the guide groove 15 is opened along the height direction of the cover plate, and the inclined section of the guide groove 15 is opened toward the outer wall of the carriage. Several sliding blocks 16 are fixed to the inner wall of the anti-funnel 14. There are two sliding blocks 16 sliding in each guide groove 15. During the sliding process of the anti-funnel 14, the two sliding blocks 16 slide in the guide groove 15. Under the guidance of the guide groove 15, the anti-funnel 14 is moved downward between the cover plate and the carriage. When garbage leaks in the carriage, the garbage liquid drips into the anti-funnel 14, thereby reducing the pollution to the external environment.

[0052] Reference Figure 5 and Figure 6 The outer wall of the carriage is slidably connected to the limit plate 18, and a traction block 19 is welded and fixed on the side wall of the limit plate 18. A clamping groove 20 is opened on the outer wall of the anti-funnel 14, and the inner wall of the clamping groove 20 is arc-shaped. The traction block 19 can be clamped in the clamping groove 20. A driving component 21 for driving the limit plate 18 to slide is provided on the side wall of the carriage. During the sliding process of the anti-funnel 14, when the traction block 19 is located at the opening of the clamping groove 20, the driving component 21 is started at this time. 1. The driving assembly 21 drives the limiting plate 18 to slide, and the limiting plate 18 drives the traction block 19 to slide into the clamping groove 20, so that the traction block 19 moves to the bottom wall of the clamping groove 20, and the traction block 19 pulls the anti-funnel 14 in the direction toward the car body, so that the anti-funnel 14 is close to the space between the cover plate and the car body. The anti-funnel 14 is limited at the same time as the cover plate, thereby improving the stability of the anti-funnel 14 and reducing the gap between the cover plate and the car body, thereby reducing the leakage of garbage in the car body.

[0053] Reference Figure 5The driving assembly 21 includes a first rack 22 welded to the inner wall of the anti-funnel 14 by a connecting rod, a first gear 23 rotatably connected to the side wall of the carriage by a rotating shaft, a second gear 24 coaxially fixed to the side wall of the first gear 23, and a second rack 25 fixed to the side wall of the limiting plate 18 by screws. The first rack 22 can mesh with the first gear 23, and the first rack 22 is driven to move during the sliding of the anti-funnel 14. When the first rack 22 moves and approaches the position of the first gear 23, the first rack 22 meshes with the first gear 23, and the first gear 23 rotates, driving the second gear 24 to rotate. The second gear 24 meshes with the second rack 25, and the second rack 25 drives the limiting plate 18 to slide, so that the traction block 19 is clamped at the bottom of the clamping groove 20.

[0054] Reference Figure 5 The side wall of the carriage is provided with a locking member 26 for limiting the sliding movement of the limit plate 18. The setting of the locking member 26 limits the sliding movement of the limit plate 18, which is more conducive to limiting the position of the limit plate 18. A sliding groove 27 is provided through the side wall of the limit plate 18. The locking member 26 includes a positioning rod 28 provided on the side wall of the carriage and a driving member 29 provided on the side wall of the carriage for driving the positioning rod 28 to slide toward the inner wall of the sliding groove 27. In this application, the driving member 29 is preferably an electric cylinder. The piston rod of the driving member 29 is fixedly connected to the positioning rod 28 by a connecting rod. When the driving member 29 is activated, the piston rod of the driving member 29 slides, causing the positioning rod 28 to slide toward the inner cavity of the sliding groove 27. The end of the positioning rod 28 slides into the sliding groove 27, positioning the limit plate 18 and limiting the sliding movement of the limit plate 18.

[0055] Reference Figure 5 A guiding slope 30 is provided at one end of the positioning rod 28 close to the limiting plate 18. When the positioning rod 28 moves toward the limiting plate 18, the guiding slope 30 abuts against the inner wall of the sliding groove 27. Under the guidance of the guiding slope 30, the limiting plate 18 tends to move toward the direction of the car body, which has a pulling effect on the limiting plate 18, so that the limiting plate 18 applies a force to the anti-funnel 14, making the anti-funnel 14 more stable.

[0056] In the second embodiment of the present application, the implementation principle of the rear door locking device of an integrated garbage compression device is as follows: after loading garbage into the compartment and closing the cover, the power member 17 is opened, and the power member 17 drives the anti-funnel 14 to slide. Under the guidance of the guide groove 15, the anti-funnel 14 moves, and the anti-funnel 14 drives the first rack 22 to move. When the first rack 22 moves to a position close to the first gear 23, the first rack 22 and the first gear 23 are engaged, driving the second gear 24 to rotate, and the second gear 24 is engaged with the second rack 25, driving the second rack 25 to move, and the second rack 22 is engaged with the second gear 23. 5 drives the limit plate 18 to slide, and the limit plate 18 drives the traction block 19 to slide, and the traction block 19 slides into the clamping groove 20. When the traction block 19 slides to the bottom of the clamping groove 20, the anti-funnel 14 moves to the bottom of the cover plate and the car body. At this time, the driving member 29 is activated, and the driving member 29 drives the positioning rod 28 to slide into the sliding groove 27. The positioning rod 28 limits the sliding of the limit plate 18, restricting the anti-funnel 14 and applying a force on the cover plate toward the car body. This reduces the leakage of garbage in the car body and improves the stability of the anti-funnel 14, thereby reducing secondary pollution to the environment.

[0057] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
