Description

Technical Field

[0001] This application relates to the technical field of automotive glass pressing tools, and in particular to an anti-bubble tool for automotive glass heating wire pressing. Background Technology

[0002] A car is an engine-driven vehicle, typically used for transporting people and goods. It is one of the most common modes of transportation in modern society, characterized by its convenience, speed, and flexibility. Cars can travel on city roads, highways, and rural roads. Car windows are one of the components of a car. After production, a protective film needs to be applied to the surface of the car windows. Car window tinting involves applying a thin film to the front and rear windshields, side windows, and sunroof. This thin film is also called solar film or explosion-proof heat insulation film. Its main functions are to block ultraviolet rays, block some heat, prevent injuries caused by sudden glass breakage, and reduce glare. At the same time, based on the one-way visibility properties of solar film, it also protects personal privacy.

[0003] A search revealed that Chinese Patent Publication No. CN222135954U discloses an automotive film squeegee with switchable Rockwell hardness, comprising a main plate, with a detachable squeegee installed on each side of the main plate, slots on both sides of the main plate, and a positioning plate installed on one side of the detachable squeegee. The positioning plate is inserted into the slot. The main plate comprises upper and lower plates, with locking holes at both ends of the upper and lower plates. Locking bolts are installed in the locking holes to lock and fix the detachable squeegee.

[0004] Regarding the aforementioned technologies, the inventors discovered the following drawbacks: A squeegee is an essential tool for applying car window film. However, during the application process, the adhesion between the film and the vehicle glass is easily reduced due to low temperatures, affecting the film's durability. Furthermore, multiple squeegees need to be switched during the application process, requiring the search for a squeegee each time. In this process, the film cannot adhere to the glass in a timely manner, leading to air bubbles and affecting the film's lifespan. Utility Model Content

[0018] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0019] This application discloses a tool for preventing air bubbles in automotive glass heating wire lamination. For example... Figure 1As shown, the device includes a fixed bracket 1. A contact mechanism is provided inside the front end of the fixed bracket 1. An air supply mechanism is provided at the top of the fixed bracket 1 near the contact mechanism. A handle 2 is fixedly connected to the rear end of the fixed bracket 1. The contact mechanism includes a film pressing roller 3. The two ends of the film pressing roller 3 are rotatably connected to the fixed bracket 1. Limiting blocks 4 are embedded inside the fixed bracket 1 at both ends of the film pressing roller 3. Guide grooves 5 are provided on the inner walls of both sides of the fixed bracket 1. Pulling rods 6 are slidably connected between the guide grooves 5. Limiting rods 7 are fixedly connected to the side walls of the pull rods 6 inside the guide grooves 5. The limiting rods 7 pass through the limiting blocks 4. When the pull rods 6 are moved backward, the pull rods 6 drive the limiting rods 7 away from the limiting blocks 4. At this time, the film pressing roller 3 is disengaged from the limiting block. The scraper is replaced after the film pressing roller 3 is rotated 90 degrees each time. A return spring 8 is sleeved on the outer surface of the limiting rod 7 between the pull rod 6 and the side wall of the guide groove 5. The setting of the return spring 8 facilitates the automatic limiting of the limiting block 4 by the limiting rod 7.

[0020] The air supply mechanism includes an air supply component 13, which is fixedly connected to the top of the fixed bracket 1. The air supply component 13 consists of a blower and a heating module. An on / off switch is provided on the top of the air supply component 13. Air supply pipes 14 are connected to both ends of the air supply component 13. An air outlet 15 is connected to the front end of the air supply pipes 14 above the pressure roller 3. The front side wall of the fixed bracket 1 is connected to both ends of the air outlet 15 by a support frame. The air outlet 15 is set at an inclined angle facing the front of the pressure roller 3. The front end of the fixed bracket 1 is set at an inclined angle. The air supply component 13 is turned on by the on / off switch. The hand handle 2 drives the pressure roller 3 to squeeze the glass film. The angle of the air outlet 15 allows the hot air to fully heat the glass film. This setting greatly reduces the phenomenon of air bubbles in the glass film.

[0021] Please see Figure 2 The grip 2 has a built-in battery that is connected to the air supply assembly 13. The rear end of the grip 2 has a built-in USB charging port 16 that is connected to the battery. The USB charging port 16 is designed to facilitate charging of the battery. The rear end of the grip 2 has a dust cover that engages with the USB charging port 16. The dust cover protects the USB charging port 16.

[0022] Please see Figure 3 The limiting block 4 is square and is set at the center of the pressing roller 3. Two through holes are opened inside the limiting block 4. The limiting rod 7 engages with the through holes. The through holes facilitate the limiting rod 7 to limit the pressing roller 3. The fixed bracket 1 has a sliding hole that is slidably connected to the limiting rod 7. The side wall of the pulling rod 6 has a sliding groove that engages with the inner wall of the guide groove 5. The two ends of the return spring 8 are fixedly connected to the side wall of the pulling rod 6 and the inner wall of the guide groove 5, respectively.

[0023] Please see Figure 4A scraper A9 is fixedly connected to the bottom front end of the film pressing roller 3, a scraper B10 is fixedly connected to the rear bottom of the film pressing roller 3, a scraper C11 is fixedly connected to the rear top of the film pressing roller 3, and a cleaning cotton 12 is snapped into the front top of the film pressing roller 3. A groove is opened on the outer surface of the film pressing roller 3 to engage with the cleaning cotton 12. The cleaning cotton 12 is designed to absorb water stains on the surface of the glass film. The design of the film pressing roller 3 allows for flexible replacement of the appropriate scraper according to the actual construction situation. At the same time, this design can promptly press the glass film, greatly reducing the occurrence of air bubbles.

[0024] The implementation principle of the automotive glass heating wire pressing film anti-bubble tool in this application embodiment is as follows: When in use, the pull rod 6 is moved backward, and the pull rod 6 drives the limiting rod 7 away from the limiting block 4. At this time, the pressing roller 3 is disengaged from the limit. Each time the pressing roller 3 is rotated 90 degrees, the scraper is replaced. The pull rod 6 drives the limiting rod 7 to re-insert into the limiting block 4 under the action of the return spring 8. The air supply assembly 13 is turned on by the on / off switch. The hand handle 2 drives the pressing roller 3 to squeeze the glass film.

[0025] 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.
