Description

Technical Field

[0001] The utility model relates to the technical field of ventilating windows for recreational vehicles, in particular to a knob-opening ventilating window for recreational vehicles. Background Art

[0002] The ventilation window is a door and window decoration with a shutter structure. Its structure is more solid and stable. In the market, there are many forms of ventilation windows, such as casement ventilation airtight doors, sliding sealing strip windtight windows and translational ventilation and breathable windows. Currently, the ventilation windows used in RVs mostly use ventilation windows with a shutter structure similar to that of the venetian blinds.

[0003] In actual use of the ventilation windows currently used in RVs, staff are required to pull a rope made of beads to adjust the size of the openings of adjacent window blades. However, as long as the ventilation windows of this structure remain ventilated, mosquitoes and dust from the outside can easily enter the vehicle through the openings between adjacent window blades, affecting the overall user experience of the RV. Therefore, it is necessary to design a knob-opening ventilation window for RVs to solve the above problem. Utility Model Content

[0026] Example

[0027] Reference Figure 1-Figure 3 , which is an embodiment of the utility model, provides a knob-opening ventilation window for a motor home, comprising: a ventilation window unit 100 and an opening adjustment unit 200.

[0028] The ventilated window unit 100 includes a ventilated window frame 101 and a window blade assembly 102 rotatably mounted in the ventilated window frame 101. A sealing pad is fixed at the edge of the ventilated window frame 101, and a knob is fixedly connected to the top of the adjusting rod 201. The setting of the sealing pad improves the sealing performance of the ventilated window frame 101 and the RV compartment.

[0029] Secondly, the opening adjustment unit 200 includes a transmission cavity and an adjustment cavity opened inside one side of the ventilation window frame 101. The ventilation window frame 101 is rotatably connected with an adjustment rod 201, and a rotating rod 203 is vertically rotatably installed in the transmission cavity. The adjustment rod 201 is inserted into the adjustment cavity and a fixed sleeve is provided with a first bevel gear 204. The side wall fixed sleeve of the ventilation window frame 101 is provided with a friction sleeve 202. The adjustment rod 201 passes through the friction sleeve 202 and is rotatably connected with the friction sleeve 202. The setting of the friction sleeve 202 increases the adjustment rod 201 and the friction sleeve 2 02 rotation damping effectively solves the problem of slight rotation of the window leaf assembly 102 due to vehicle bumps after the rotation angle of the window leaf assembly 102 is adjusted. The lower end of the rotating rod 203 is inserted into the adjustment cavity and is fixedly connected to the second bevel gear 205 meshing with the first bevel gear 204. A plurality of groups of evenly distributed third bevel gears 206 are fixedly sleeved on the rotating rod 203. A plurality of groups of evenly distributed fourth bevel gears 207 are rotatably installed on the inner wall of the transmission cavity, and each fourth bevel gear 207 is meshed with the third bevel gear 206.

[0030] The window blade assembly 102 includes a plurality of rectangular frames 102a rotatably mounted in the ventilation window frame 101. The end of the rectangular frame 102a away from the third bevel gear 206 is fixedly connected to a rotating shaft 102e, and the rotating shaft 102e is rotatably connected to the inner wall of the ventilation window frame 101. The setting of the rotating shaft 102e can support the rotation of the rectangular frame 102a from the other end. A ventilation yarn 102b is set in each rectangular frame 102a, and one side of the top of the rectangular frame 102a is set to a rounded corner 102d. , and an arc-shaped defective portion 102c matching the rounded corner portion 102d is provided on one side of the lower end of the rectangular frame 102a. The matching use of the rounded corner portion 102d and the arc-shaped defective portion 102c improves the docking sealing of the two adjacent rectangular frames 102a. A transmission rod is fixedly connected to the center of one end of the rectangular frame 102a close to the transmission cavity. The transmission rod is inserted into the transmission cavity and fixedly connected to the center of the fourth bevel gear 207, and the transmission rod is frictionally rotated with the side wall of the ventilation window frame 101.

[0031] During use, when the RV is parked in a place with strong wind and sand and many mosquitoes, in order to ensure that the ventilation window can play a normal ventilation role and the mosquitoes and wind and sand dust from the outside cannot enter the RV, the first bevel gear 204, the second bevel gear 205 and the rotating rod 203 are driven to rotate by rotating the adjusting rod 201, and the third bevel gear 206 fixedly mounted on the rotating rod 203 drives the multiple groups of rectangular frames 102a to rotate through the fourth bevel gear 207. When the adjacent rectangular frames 102a are against each other, the adjacent openings of the rectangular frames 102a are closed, which completely blocks the possibility of mosquitoes, wind and sand and dust entering the car, and the airflow inside and outside the RV can be exchanged through the breathable yarn 102b in the rectangular frame 102a.

[0032] When the area where the RV is parked has less dust and fewer mosquitoes, the size of the opening of the adjacent rectangular frame 102a can be adjusted by rotating the adjustment rod 201. The use function of the ventilation window can be flexibly adjusted according to the different parking areas, thereby improving the user experience of the RV.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
