Description

Technical Field

[0001] This utility model relates to the field of automotive repair technology, and in particular to an automotive glass removal device. Background Technology

[0002] Most automotive glass removal and repair workers still use two people pulling steel wires or metal tools such as pullers, scrapers, and blades to remove automotive glass. All of these methods rely on brute force, requiring repairmen to exert a great deal of strength to successfully remove the glass.

[0003] To improve this situation, the repair industry has designed many specialized car glass removal tools. These tools use cutting wires to cut the glass adhesive, thus quickly removing the car glass and protecting repair personnel. However, these tools still have the following drawbacks: the suction cups are manual, resulting in slow fixation speed; and the split structure affects disassembly efficiency. Utility Model Content

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Depend on Figures 1 to 5It is known that an automotive glass removal device includes an electric suction cup 1. A handle 8 is provided above the electric suction cup 1 for quick fixation to the inside of the automotive glass. A fixing plate 2 is connected above the electric suction cup 1, and the fixing plate 2 is fixedly connected to the electric suction cup 1 by screws. Guide wheels 3 are provided at the bottom of the four corners of the fixing plate 2. Two winding mechanisms are provided on one side of the fixing plate 2. Each winding mechanism includes a rotating shaft 4, with a winding wheel 5 at the bottom of the rotating shaft 4. A ratchet 6 is provided on the winding wheel 5. A limiting pin 7, which cooperates with the ratchet 6, passes through the fixing plate 2. The bottom of the limiting pin 7 has an inclined surface. The ratchet 6 and the limiting pin 7... The ratchet 6 is designed to rotate in one direction. One end of the cutting wire is fixed to a winding wheel 5. After passing through four guide wheels 3, the other end of the cutting wire passes through the inner edge of the car glass and exits outside the car. The cutting wire is then inserted into the gap of the adhesive position along the edge of the glass, circles the car once, and then passes inside the car and is fixed to another winding wheel 5. The rotating shaft 4 is then rotated to tighten the cutting wire. The wire cuts the sealant along the edge of the car glass in a clockwise or counterclockwise direction. The angle of the cutting wire is changed by the guide wheels 3 until all the sealant on the car glass is cut. Then the electric suction cup 1 can be removed.

[0022] In this invention, the rotating shaft 4 is fixed to the fixed plate 2 by the bearing 9, which can ensure the rotation of the rotating shaft 4, reduce friction, and extend service life.

[0023] In this invention, the upper end of the rotating shaft 4 is hexagonal prism-shaped, and the rotating shaft 4 can be operated by a wrench or an electric drill, which is convenient and quick.

[0024] In this utility model, the ratchet 6 has multiple limiting grooves 10 around its circumference, and the limiting pin 7 can be inserted into the limiting groove 10 to limit the ratchet 6.

[0025] In this utility model, a bushing 11 is provided on the fixing plate 2, and a directional groove 12 is provided on the bushing 11. A limiting pin 7 is inserted into the bushing 11 to limit the one-way rotation of the ratchet 6. The limiting pin 7 includes a pin sleeve 13 that is inserted into the bushing 11 and an inner pin 14 inside the pin sleeve 13. A spring 15 is provided at the top of the inner pin 14, and a limiting block 16 is provided on the inner side of the pin sleeve 13.

[0026] The different directions in which the limiting pin 7 is inserted into the directional groove 12 can change the direction of the unidirectional rotation of the ratchet 6, thereby better controlling the cutting line. When the ratchet 6 rotates, it pushes the inner pin 14 to retract into the pin sleeve 13, thus completing the rotation of the ratchet 6. When it rotates in the opposite direction, the ratchet 6 cannot rotate due to the obstruction of the inner pin 14, thus playing a unidirectional limiting role.

[0027] The bottom of the fixing plate 2 is provided with a retaining ring 17 located outside the ratchet 6, which can prevent the cutting wire from entering the ratchet 6 and causing the wire to get stuck, thus ensuring the smooth progress of the glass disassembly work.

[0028] Compared with the prior art, this utility model has the following advantages: it adopts an electric suction cup, which can quickly and firmly fix the glass to the car glass and is not easy to fall off, ensuring the smooth removal of the glass; it adopts an integrated fixing plate, which has a compact structure and is easy to use; the rotating shaft is equipped with a bearing on the outside, which reduces friction and extends service life; the improved ratchet structure is easier to operate and has less wear, thereby extending service life.
