[0031] [First embodiment]

[0032] like Figure 1-6 The figure shows a bus heat dissipation duct provided by the first embodiment of the utility model, including a shell 1, and a clamping plate 4 is fixedly connected to the top of the shell 1. The connection between the shell 1 and the bus compartment can be achieved by inserting the clamping plate 4 into the top of the bus compartment and using tools such as bolts to pass through the mounting holes inside the clamping plate 4; a luggage rack plate 5 is fixed to one end of the shell 1, and a ventilation plate 6 is provided at the bottom of the shell 1. The air vents inside the ventilation plate 6 can be used to adjust the temperature and ventilate the compartment.

[0033] The outstanding contribution of this embodiment over the prior art is that: the outer edge of the luggage rack plate 5 is provided with a plurality of convenient devices 2 through the auxiliary device 3. By providing the convenient devices, the height position of the curved part of the edge of the baffle plate can be adjusted by pulling the baffle plate, so that it is convenient for passengers to place luggage on the luggage rack. After the baffle plate is released, the baffle plate is restored to its original position by the elastic member, so that the position of the luggage on the luggage rack plate is restricted, the overall practicality of the heat dissipation duct is improved, and it is convenient for passengers to place luggage on the luggage rack; at the same time, relying on the resetting effect of the elastic member, the elastic member can be compressed for larger-sized luggage to increase the size for placement, which can facilitate the placement of luggage of different sizes and improve applicability; and by providing the auxiliary device, the separate loading and unloading and later maintenance of baffles at different positions are facilitated, and the convenience of replacement and maintenance is improved.

[0034] like Figure 2-5As shown, the convenient device 2 in this embodiment includes a U-shaped block 21, and a baffle 22 is rotatably connected inside the notch of the U-shaped block 21. The outer edge of the baffle 22 is set to an arc shape extending upward to effectively block and position the placed luggage to prevent unexpected falling. A plurality of convex strips 210 are fixed on the top of the baffle 22. The convex strips 210 are made of rubber material. The friction between the baffle 22 and the surface of the luggage can be increased by the rubber convex strips, further reducing the possibility of the luggage falling out of the luggage rack. The bottom of the U-shaped block 21 is fixedly connected to a U-shaped rod 23. The bottom of the U-shaped rod 23 is bonded with a pad 29. The pad 29 is made of sponge material. The sponge pad 29 can minimize the damage caused by the collision of some passengers' bodies with the U-shaped rod. An elastic member 24 is set at the bottom of the baffle 22. The upper and lower ends of the elastic member 24 are respectively fixedly connected to the bottom of the baffle 22 and the inner side of the U-shaped rod 23. By providing an elastic member, when the luggage needs to be placed on the luggage rack, the baffle can be pulled to rotate downward and compress the elastic member, so that the bent end of the baffle deflects downward, making it easier for the passenger to place the luggage on the luggage rack. The baffle can then be released and restored to its original shape through the elastic member, pushing the baffle to rotate in the original direction to return to its original position.

[0035] To further facilitate the control of the baffle, a rectangular rod 25 is fixedly connected to the bottom of the baffle 22, and a triangular block 26 is fixedly connected to the bottom of the rectangular rod 25. The inner wall of the triangular block 26 is provided with a plurality of grooves. This arrangement makes it possible to conveniently pull the rectangular rod to control the baffle to rotate by holding the triangular block at the grooves on the inner wall of the triangular block and pulling the triangular block.

[0036] In order to reinforce and limit the compression and elastic reset process of the elastic member, a cylinder 27 is fixed to the inner top of the U-shaped rod 23, and a round rod 28 is fixed to the bottom of the baffle 22. The bottom of the round rod 28 is located inside the cylinder 27 and can move up and down and telescopically relative to the cylinder 27, thereby minimizing the irregular deformation that may occur to the elastic member when compressed.

[0037] like Figure 3-4 As shown in Figure 6, the auxiliary device 3 in this embodiment includes a rectangular block 31, which is fixedly connected to the inner side of the U-shaped block 21. The inner thread of the rectangular block 31 is connected with a bolt 34. A plurality of through holes 33 are provided at the bottom end of the luggage rack plate 5, and a plurality of card slots 32 are provided at the outer side of the luggage rack plate 5. The rectangular block 31 at one end of the U-shaped block 21 is inserted into the card slot on one side of the luggage rack plate, and then the bolt is inserted into the rectangular block through the through hole and the bolt is rotated to thread the bolt with the inner wall of the rectangular block. The rectangular block and the convenient device can be installed on one side of the luggage rack plate. The bolt is rotated to disengage the bolt from the inner wall of the rectangular block, and then the rectangular block is pulled out from the inside of the card slot to remove the convenient device. Therefore, by setting the auxiliary device, the separate loading and unloading and later maintenance of the baffles at different positions are facilitated, thereby improving the convenience of replacement and maintenance.

[0038] As a further preferred embodiment, a circular groove 35 is provided at the bottom of the luggage rack plate 5 corresponding to the position of the through hole 33. The aperture of the circular groove 35 is larger than the aperture of the through hole 33, so as to accommodate the nut at the bottom of the bolt, so that the nut does not protrude from the surface of the luggage rack plate, and to avoid the bolt from shaking due to collision during daily use of the luggage rack plate, which affects the fixing stability of the convenient device. In addition, an elastic rope 36 is fixedly connected to one side of the U-shaped block 21, and the end of the elastic rope 36 away from the U-shaped block 21 is fixedly connected to the bolt 34. By providing the elastic rope, the bolt can be temporarily fixed to one side of the U-shaped block, which is convenient for taking the bolt for use, while reducing the possibility of the bolt accidentally falling and losing when disassembling the convenient device.

[0039] The specific working process of this embodiment is as follows:

[0040] (1) When installing the cooling duct of a bus, insert the clamping plate 4 at the top of the housing 1 into the top of the bus compartment and clamp it, and use tools such as bolts to pass through the mounting holes at the top of the clamping plate 4 to connect it to the compartment;

[0041] (2) Then, at one end of the luggage rack plate 5, a rectangular block 31 on one side of the plurality of U-shaped blocks 21 is inserted into the interior of the slot 32, and then a bolt 34 at the bottom end of the U-shaped block 21 is inserted into the rectangular block 31 through the through hole 33 at the bottom end of the luggage rack plate 5, and the bolt 34 is rotated so that the bolt 34 is threadedly connected to the inner wall of the rectangular block 31 to fix the rectangular block 31 and the convenient device 2 on one side of the luggage rack plate 5;

[0042] (3) When placing luggage on the luggage rack plate 5, the user can hold the triangular block 26 and pull the rectangular rod 25 to rotate the baffle 22 downward and compress the elastic member 24 at the bottom, so as to facilitate placing the luggage on the luggage rack. After the luggage is placed, the rectangular rod 25 is released, and the elastic member 24 returns to its original shape and pushes the baffle 22 to rotate in the original direction to return to its original position, thereby limiting the position of the luggage on the luggage rack plate 5. When the bus is running, the ventilation holes of the ventilation plate 6 at the bottom of the shell 1 can be opened to assist in dissipating heat inside the compartment.
