Description

Technical Field

[0001] This application relates to the technical field of automotive triangular window diaphragm positioning, and in particular to a small diaphragm positioning device specifically for automotive triangular windows. Background Technology

[0002] Car window tinting involves applying a thin film to the front and rear windshields, side windows, and sunroof of a vehicle. This film, also known as solar film or explosion-proof heat insulation film, primarily blocks ultraviolet rays, reduces heat, prevents injuries from sudden glass breakage, and reduces glare. Additionally, its one-way visibility helps protect privacy. Furthermore, it reduces damage to interior items and occupants caused by ultraviolet radiation, lowers interior temperature through physical reflection, reduces the need for air conditioning, and thus lowers fuel consumption and saves money.

[0003] A search revealed Chinese Patent Publication No. CN217198840U, which discloses a convenient positioning device for applying automotive window film. The device includes two identical strip-shaped base plates. Vertical rods are connected to the upper surfaces of both base plates near their ends, and positioning components are installed between the vertical rods and the base plates. A top plate is connected to the top of the four vertical rods, and a push handle is installed on the upper surface of the top plate. A through groove is formed on the top plate, and a movable platform is movably arranged within the groove. Slider blocks are symmetrically connected to the movable platform. Sliding grooves are symmetrically formed on the sidewalls of the through groove, and the sliders are slidably connected to the sliding grooves. Two symmetrically arranged threaded rods are rotatably mounted on the bottom of the movable platform. A matching movable plate is threaded onto the two threaded rods, and a U-shaped rod is slidably threaded through the movable plate.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following defects: Existing diaphragm positioning devices lack a positioning mechanism for triangular windows. In existing technologies, large diaphragms are typically directly pasted onto the triangular window and then cut. Due to the small area of ​​the triangular window, the diaphragm is prone to folding during pasting, resulting in the diaphragm being scrapped. Furthermore, the triangular window area cannot be positioned, leading to significant waste after the diaphragm is cut. Utility Model Content

A scale 12 is embedded on the left top wall of support frame A1 below the indicator needle 11. The scale 12 is set to facilitate observation of the angle between support frame A1 and support frame B2. The sliding block 4 is moved according to the position of the other two corners until the contact rod 5 contacts the two corners. At this time, the area of ​​the triangular window is determined. The cut film is pasted on the nano double-sided tape 7 for installation. A handle 18 is fixedly connected between the front side wall and the top wall of support frame B2 above the adjusting screw 13. The handle 18 is set at the center line of support frame B2.

[0025] The implementation principle of the small diaphragm positioning device for automotive triangular windows in this embodiment is as follows: When in use, hold the handle 18 and contact the device with the triangular window. First, contact the contact rod 5 at the front end of the support frame B2 with the bottom corner of the triangular window. Rotate the adjusting screw 13, which drives the pushing block 14 to move. The pushing block 14 drives the pushing rod 17 to move. The pushing rod 17 drives the support frame A1 to rotate, so that the support frame A1 and the support frame B2 are in contact with the edge of the bottom corner of the triangular window. Move the sliding block 4 according to the position of the other two corners until the contact rod 5 contacts the two corners. At this time, the area of ​​the triangular window is determined. Then, paste the cut diaphragm onto the nano double-sided adhesive 7 for installation.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
