Description

Technical Field

[0001] The utility model relates to the technical field of skylights, in particular to a skylight with a filtering function. Background Art

[0002] The skylights installed on medium and large excavators can effectively circulate air in the vehicle and increase the intake of fresh air. When operating the excavator, the operator can choose to open or close the skylight as needed to obtain a better view and ventilation and improve comfort.

[0003] When the existing sunroof is opened for use in summer, external mosquitoes often enter the car through the sunroof, causing inconvenience to users when using the car. In the patent application with authorization publication number CN214215448U, authorization publication date 2021-09-17, and name "A car sunroof with a rainwater diversion structure", an insect-proof net is connected to the left end of the sunroof. When the sunroof is retracted into the right frame, the insect-proof net moves with the sunroof to cover the window, while meeting the ventilation and air permeability of the car, mosquitoes are filtered out at the same time; in the actual use of the above-mentioned device, since the two ends of the insect-proof net are respectively connected to the winding shaft and the sunroof, when the insect-proof net is used for a long time, impurities will adhere to the insect-proof net, thereby affecting the ventilation effect of the sunroof. However, the existing sunroof is inconvenient to quickly disassemble and clean the insect-proof net, which is inconvenient to use.

[0004] Therefore, we propose a skylight with filtering function to solve the above problems. Utility Model Content

[0005] 1. Technical problems to be solved by the utility model:

[0006] The purpose of the utility model is to provide a skylight with a filtering function to solve the problems in the current market raised by the above background technology.

[0007] 2. Technical solution:

[0008] To achieve the above object, the utility model provides the following technical solution: a skylight with filtering function, comprising a frame installed on the top of a cab, a skylight body installed above the frame, a mounting frame installed inside the frame, and a mosquito-proof filter installed inside the mounting frame;

[0009] The mounting frame is composed of a fixed frame and a movable plate, and the fixed frame is fixedly installed on the inner wall of the frame, and a connecting column is fixedly installed on the lower end of the fixed frame, and a positioning block is slidably installed inside the connecting column, and a control module is installed inside the side of the fixed frame, and the control module is used to pull the positioning block back to the inside of the connecting column.

[0010] Furthermore, a fixing block is fixedly installed inside the connecting column, and a pressure spring is connected between the fixing block and the positioning block.

[0011] Through the above technical solution, the positioning block can realize elastic expansion and contraction inside the connecting column under the action of the pressure spring.

[0012] Furthermore, the control module includes a gear roller with a bearing installed inside the fixed frame, a take-up roller is fixedly installed on the end of the gear roller, and the side of the take-up roller is fixedly connected to one end of the traction line, and the other end of the traction line is fixed to the end of the positioning block.

[0013] Through the above technical solution, when the gear roller rotates, it can drive the take-up roller to reel in the traction line, thereby pulling the positioning block to move.

[0014] Furthermore, a driving member is provided on the side of the gear roller, and the driving member slides up and down in the interior of the fixing frame, and the driving member is integrated with a linkage plate and a rack, and the rack and the gear roller form a meshing structure design.

[0015] Through the above technical solution, when the linkage plate is pressed, the rack can be driven to engage with the gear roller, thereby driving the gear roller to rotate.

[0016] Furthermore, an upper end of one side of the positioning block is attached to the lower part of the movable plate, and the positioning block is designed in a trapezoidal structure.

[0017] Through the above technical solution, when the movable plate is installed, the positioning block will not prevent the movable plate from being sleeved on the connecting column.

[0018] Furthermore, the upper and lower ends of the filter screen are respectively attached to the inner part of the lower end of the fixing frame and the upper end surface of the movable plate.

[0019] Through the above technical solution, the filter screen can be fixed between the fixing frame and the movable plate.

[0020] 3. Beneficial effects:

[0021] The technical solution provided by the utility model is adopted. Compared with the prior art, the utility model has a skylight with a filtering function. The filter screen installed inside the frame is used to filter mosquitoes from the outside to avoid affecting the work of the operator in the cab. At the same time, the filter screen can be quickly disassembled and cleaned to ensure the ventilation effect of the skylight. The specific contents are as follows:

[0022] The filter installed inside the frame is used to filter mosquitoes from the outside to prevent mosquitoes from entering the cab and affecting the operator's work. After long-term use, when the impurities attached to the filter affect the filtering effect, the linkage plate is pressed, and the linkage plate drives the rack to move up. During the upward movement of the rack, the meshing action between the rack and the gear roller is used to drive the take-up roller to rotate, and the traction line is wound up. Then, when the take-up roller rotates, the positioning block can be pulled back to the inside of the connecting column under the action of the traction line, and then the movable plate can be removed under the fixed frame, so that the filter between the fixed frame and the movable plate can be removed, and the filter can be cleaned, and then the filter and the movable plate are installed under the fixed frame in turn. During the installation of the movable plate, since the positioning block is designed as a trapezoidal structure, the positioning block will not prevent the movable plate from being set on the outside of the connecting column, and then under the action of the pressure spring, the positioning block is prompted to extend to limit the installed movable plate, thereby realizing the rapid disassembly and assembly of the filter.
