Description

Technical Field

[0001] The utility model relates to the technical field of material application, in particular to a device for flattening automobile exterior decorative strips. Background Art

[0002] Car exterior decorative strips are usually made of polyvinyl chloride, which has good weather resistance and is not easy to fade. Even if scratched, it can be restored to a glossy finish by polishing. This type of decorative strip not only increases the beauty of the side of the car body, but also perfectly matches the curvature of the car body, providing a durable and non-deformation effect.

[0003] Existing decorative strip flattening tools are generally single rollers. If the size of the roller is similar to that of the decoration, the roller may be skewed due to uneven pressure during the rolling process, and the paint surface may be easily damaged, causing quality problems such as debonding of the decorative strip. Therefore, the size of the roller is usually larger than the decorative strip. However, this flattening tool is only suitable for use on smooth parts of the car body. If the decorative strip is attached to a groove on the car surface, this flattening tool will not be usable due to the large size of the roller.

[0004] Therefore, the utility model provides a device for flattening automobile exterior decorative strips to solve the above-mentioned problem. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a device for flattening automobile exterior decorative strips, such as Figure 1 and Figure 2 As shown, the flattening device includes a mounting block 1, a first roller 2 rotatably mounted on the bottom of the mounting block 1, a connecting block 6 movably mounted inside the mounting block 1, a slide rod 7 fixedly mounted on the connecting block 6, a sleeve 9 slidably mounted on the slide rod 7, a connecting plate 14 fixedly mounted on the sleeve 9, and a second roller 4 rotatably mounted on the connecting plate 14.

[0024] When the device is used, the first roller 2 needs to be attached to the surface of the decorative strip, and then the device is pushed. The first roller 2 rolls on the surface of the decorative strip under the influence of friction, so as to flatten the decorative strip. The second roller 4 mainly fits the vehicle body veneer, and its setting is mainly used to assist the first roller 2. The second roller 4 and the connecting plate 14, the slide bar 7, the sleeve 9 and the connecting block 6 can be used as a whole, which can be installed on the mounting block 1 or removed. The slide bar 7 is fixed on the connecting block 6, and the sleeve 9 can carry the second roller 4 to move vertically on the slide bar 7 When the car surface is relatively flat, the second roller 4 can reduce the possibility of deviation when only the first roller 2 is working and moving. When the decorative strip is attached to the concave surface, when the device is used to fit the first roller 2 to the decorative strip, the second roller 4 will be squeezed by the car surface, so that the sleeve 9 brings the second roller 4 to shrink a certain distance to adapt to the situation of the car surface. If the concave surface is deep and the second roller 4 affects the normal use of the device, the second roller 4 can also be directly removed from the mounting block 1 through the connecting block 6, and only the first roller 2 is used to perform the flattening work.

[0025] Further, in order to enable the sleeve 9 to be reset after being moved, as Figure 2 and Figure 3 As shown, a first spring 8 is sleeved on the side surface of the slide rod 7 , the top of the first spring 8 is fixedly connected to the bottom of the connecting block 6 , and the bottom of the first spring 8 is fixedly connected to the top of the sleeve 9 .

[0026] The first spring 8 is arranged so that when the second roller 4 is squeezed by the surface of the car, the sleeve 9 can shrink the second roller 4 by a certain distance. When the squeezing force disappears, the sleeve 9 can return the second roller 4 to its original position under the action of the first spring 8 .

[0027] Furthermore, in order to enable the connection block 6 to be fixed and disassembled, as Figure 1 , Figure 2 and Figure 4 As shown, a limiting block 12 is fixedly connected to the mounting block 1, an adjusting block 13 is movably connected to the top of the limiting block 12, a fixing rod 10 is rotatably connected inside the adjusting block 13, the fixing rod 10 is slidably connected inside the limiting block 12, and a second spring 11 is sleeved on the side surface of the fixing rod 10.

[0028] A circular groove for the fixing rod 10 to slide is provided inside the mounting block 1 , and a square groove for the connecting block 6 to slide is provided inside the mounting block 1 . The fixing rod 10 is inserted into the connecting block 6 through the circular groove.

[0029] A groove for inserting the fixing rod 10 is provided inside the connecting block 6. Prying the adjusting block 13 can drive the fixing rod 10 to move upward to release the stuck connecting block 6, so that it can be removed from the mounting block 1. The same is true during installation.

[0030] In order to improve the stability of the first roller 2 during operation, Figure 1 and Figure 2 As shown, the bottom of the mounting block 1 is fixedly connected to a fixing plate 16 , the first roller 2 is internally rotatably connected to a first rotating shaft 15 , the side surface of the first rotating shaft 15 is fixedly connected to the bottom of the fixing plate 16 , and the first roller 2 is sleeved with a first rubber ring 3 .

[0031] The first roller 2 is sleeved on the fixed first rotating shaft 15 and rotates, so that it has good stability when working. The first rubber ring 3 on the first roller 2 plays a good buffering role when the device is working, reducing the possibility of scratches on the surface of the decorative strip caused by direct contact between the first roller 2 and the decorative strip.

[0032] Furthermore, in order to facilitate the use of the device by the staff, Figure 1 and Figure 2 As shown, a handle 17 is fixedly connected to the mounting block 1 , a second rotating shaft 18 is rotatably connected inside the second roller 4 , the second roller 4 is fixedly connected inside the connecting plate 14 , and a second rubber ring 5 is sleeved on the second roller 4 .

[0033] The setting of the handle 17 enables the staff to directly operate the device through the handle 17, which is very convenient. The setting of the second rubber ring 5 on the second roller 4 is to reduce the possibility of scratches on the body surface caused by direct contact between the first roller 2 and the body surface.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
