Description

Technical Field

[0001] The utility model relates to the technical field of dustproof nets for air-conditioning covers, and in particular to a dustproof net structure for an air-conditioning cover of a bus. Background Art

[0002] The principle of bus cooling is to use a compressor to compress the refrigerant, which turns it into liquid and releases a large amount of heat, causing its temperature to rise significantly. At this time, the refrigerant transfers heat to the outside world through the heat-conducting surface, and the large amount of heat released by the refrigerant is transferred to the outside world. Then, by reducing the pressure, the refrigerant is vaporized, and the refrigerant absorbs a large amount of heat when it vaporizes. At this time, the refrigerant contacts the air inside the car through another heat-conducting surface, absorbing a large amount of heat inside the car, and then the temperature-regulated air is blown into the car through the fan. When heating is needed, the above process is controlled to transfer a large amount of heat outside the car to the car.

[0003] When the bus air conditioner is in use, an air conditioner cover needs to be installed on the top. An air ducting port is provided on the outside of the air conditioner cover, and a dustproof net is installed inside the air ducting port. The components inside the air conditioner can be protected by the dustproof net. When the dustproof net is installed, it is connected to the air conditioner cover by multiple sets of fixing bolts so that the dustproof net can be installed. Through the installation of the fixing bolts, when the dustproof net needs to be disassembled for maintenance, it needs to be disassembled with the help of auxiliary tools, which is more troublesome.

[0004] Therefore, it is particularly important to improve the dustproof net structure of the existing bus air-conditioning cover, design a new dustproof net structure of the bus air-conditioning cover to solve the above technical defects, and improve the practicality of the dustproof net structure of the overall bus air-conditioning cover.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Example

[0023] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0024] A dustproof net structure for a bus air conditioner cover comprises an air conditioner cover body 1, a through slot 2 is provided on the inner side of the air conditioner cover body 1, an air induction guide port 3 is provided on the inner wall of the through slot 2, a dustproof net 4 is installed outside the through slot 2, and a quick-release component 5 is installed between the dustproof net 4 and the through slot 2;

[0025] The quick-release assembly 5 is used for quickly disassembling and assembling the dustproof net 4 .

[0026] For further information, see Figure 5 and Figure 6 In this embodiment, the quick-release assembly 5 includes a fixed seat 501, an active rod 502, a connecting rod 503, a driving rod 504, a block 505 and a hook 506. The fixed seat 501 is respectively installed at the four corners of the dustproof net 4, the active rod 502 is installed inside the fixed seat 501, the connecting rod 503 is installed inside the active rod 502, the driving rod 504 is installed outside the connecting rod 503 away from the active rod 502, and the driving rod 504 extends to the outside of the fixed seat 501, the block 505 is installed at the end of the driving rod 504 away from the fixed seat 501, and the hook 506 Installed between the air ducting port 3, when the air conditioner is used for a long time, some dust will adhere to the inside of the dustproof net 4. At this time, the dustproof net 4 needs to be cleaned. When the cleaned dustproof net 4 needs to be installed, the active rod 502 is toggled to make the active rod 502 swing until the active rod 502 is parallel to the fixed seat 501, thereby driving the connecting rod 503 to swing, so that the driving rod 504 completes the rising work, so that the block 505 and the hook 506 are fitted together, and then the block 505 is driven to rise, so that the block 505 and the hook 506 are fitted together, thereby completing the installation.

[0027] Among them, see Figure 5 and Figure 6 In this embodiment, ears are symmetrically installed at the bottom of the fixing seat 501, bolts are installed inside the ears, and the fixing seat 501 is fixedly connected to the dustproof net 4 through the bolts. By inserting the bolts into the outside of the dustproof net 4 and rotating the bolts, the fixing seat 501 and the dustproof net 4 are fixedly connected.

[0028] Secondly, please refer to the figure. In the present embodiment, a slide groove 507 is provided on the front side of the fixed seat 501. An extrusion block 508 is installed between the slide grooves 507. A spring is installed inside the extrusion block 508. The extrusion block 508 is slidably connected to the inside of the fixed seat 501 through the spring. When the active rod 502 is moved, it will swing inside the slide groove 507 and swing to the rear side of the extrusion block 508. Due to the expansion and contraction function of the spring, the upward force will continue to be transmitted to the inside of the extrusion block 508, so that the extrusion block 508 blocks the active rod 502 to prevent the active rod 502 from deviating after being parallel to the fixed seat 501.

[0029] Furthermore, please see Figure 5 and Figure 6 In this embodiment, square grooves are provided inside the active rod 502 and the driving rod 504, and both ends of the connecting rod 503 are rotatably connected to the inside of the square grooves. By rotating the two ends of the connecting rod 503 with the square grooves, the connecting rod 503 acts as a medium to generate linkage between the active rod 502 and the driving rod 504.

[0030] For further information, see Figure 5 and Figure 6 In this embodiment, a waist-shaped groove 509 is opened on the top of the driving rod 504, and a fixed column 510 is installed inside the waist-shaped groove 509. A limiting block is installed on the top of the fixed column 510, and the size of the limiting block is larger than the diameter of the waist-shaped groove 509. Through the swing of the connecting rod 503, the square groove will be squeezed through one end of the connecting rod 503, so that the driving rod 504 rises and moves along the fixed column 510 through the waist-shaped groove 509, so that the driving rod 504 completes the limit in the upward movement and makes a straight upward movement.

[0031] For further information, see Figure 5 and Figure 6 In this embodiment, a handle 6 is installed at one end of the active rod 502 away from the fixed seat 501. A finger groove is opened on the outside of the handle 6, and an anti-slip pad is installed on the top of the handle 6. The active rod 502 can be moved through the handle 6. The handle 6 can increase the force points, making it more labor-saving to swing the active rod 502. Through the design of the finger groove and the anti-slip pad, the handle 6 can fit the operator's hand perfectly, making it more convenient to use.

[0032] In this embodiment, the implementation scenario is specifically as follows: after the air conditioner has been used for a long time, some dust will adhere to the inside of the dustproof net 4. At this time, the dustproof net 4 needs to be cleaned. When the cleaned dustproof net 4 needs to be installed, the operator holds the handle 6 and turns the handle 6 to swing the active rod 502 until the active rod 502 is parallel to the fixed seat 501. The active rod 502 swings to the rear side of the extrusion block 508. Due to the expansion and contraction function of the spring, the upward force will continue to be transmitted to the inside of the extrusion block 508, so that The squeezing block 508 blocks the active rod 502 to prevent the active rod 502 from being offset after being parallel to the fixing seat 501, thereby driving the connecting rod 503 to swing. The square groove is squeezed by one end of the connecting rod 503, so that the driving rod 504 rises and moves along the fixing column 510 through the waist-shaped groove 509, so that the driving rod 504 completes the limit in the upward movement and makes a straight upward movement, and then drives the clamping block 505 to rise, so that the clamping block 505 and the hook 506 fit together, thereby completing the installation.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
