Description

Technical Field

[0001] The utility model relates to the technical field of artificial leather, in particular to an artificial leather which is easy to roll up. Background Art

[0002] Artificial leather, also known as synthetic leather or imitation leather, is a kind of imitation leather material made of artificial materials. It is used in clothing, footwear, furniture, car interiors, etc. Because of its economical and cheap, it has been widely used.

[0003] After the artificial leather is manufactured, it is generally rolled up. However, since the artificial leather itself has a certain thickness and elasticity, the interior of the artificial leather is prone to deformation after rolling up, which causes the internal elastic potential energy of the artificial leather to increase after rolling up, making it prone to rebound, thereby increasing the space occupied by the artificial leather and making it easy to spread out quickly, which is not conducive to storage. Utility Model Content

[0004] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the utility model is to provide an artificial leather that is easy to roll up and is used to reduce the rebound of the artificial leather body after rolling up.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an artificial leather that is easy to roll up, comprising an artificial leather body, a strip groove is provided at the upper edge of the artificial leather body, a convex strip that matches the strip groove is provided on the lower side of the artificial leather, a carrier frame is fixedly installed on one side of the artificial leather, support frames are rotatably installed on both sides of the carrier frame, the support frames are elastic telescopic rods, rollers are installed on the two support frames, a gear ring is fixedly installed on the support frame, and a clamping piece that is engaged with the teeth of the gear ring is slidably installed on the carrier frame.

[0006] Furthermore, there are two strip-shaped grooves, which are respectively located on both sides of the artificial leather body, and there are two convex strips, which are respectively located on both sides of the artificial leather body.

[0007] Furthermore, the roller is rotatably connected to the support frame.

[0008] Furthermore, it also includes a connecting rod slidably arranged on the supporting frame, the supporting frame is provided with a circular groove for inserting the connecting rod, the supporting frame is rotatably mounted on the connecting rod, one end of the connecting rod away from the circular groove is fixedly connected to the clamping member, and a locking member for limiting the rotation of the connecting rod is arranged in the circular groove.

[0009] Furthermore, the locking element comprises a protrusion fixedly mounted on the connecting rod, and the inner wall of the circular groove is provided with a square groove for the protrusion to slide.

[0010] Furthermore, a spring is provided in the circular groove for driving the connecting rod to slide into the circular groove.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the roller is located on the outside of the artificial leather body, and during the rolling process of the artificial leather body, the roller is always in contact with the outside of the artificial leather body, as the outer diameter of the cylinder formed after the artificial leather body is rolled up gradually increases, the length of the support frame connected to the roller is also gradually getting longer, and at the same time, the elastic potential energy accumulated in the support frame is also increasing accordingly. When the artificial leather body is completely rolled up, the limiting work of the clamping ring is released by the clamping piece, so that the support frame can rotate relative to the supporting frame, thereby facilitating the movement of the roller close to the end of the artificial leather body, so that the artificial leather body roughly forms a cylinder, and at the same time, the roller can also reduce the rebound of the artificial leather body after rolling up.

[0018] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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.

[0019] See also Figure 1 , Figure 3 and Figure 4The present embodiment provides an artificial leather that is easy to roll up, including an artificial leather body 1, a strip groove 2 is opened at the upper edge of the artificial leather body 1, a convex strip 3 adapted to the strip groove 2 is arranged on the lower side of the artificial leather, a carrier frame 4 is fixedly installed on one side of the artificial leather, and support frames 5 are rotatably installed on both sides of the carrier frame 4. The support frames 5 are elastic telescopic rods, and rollers 6 are installed on the two support frames 5. A gear ring 7 is fixedly installed on the support frame 5, and a clamping piece 8 engaged with the teeth of the gear ring 7 is slidably installed on the carrier frame 4.

[0020] When the artificial leather needs to be rolled up, the artificial leather body 1 is rolled up around the carrier frame 4 with the carrier frame 4 as the center. During the rolling process, the convex strip 3 on one side of the artificial leather is just inserted into the corresponding strip groove 2, which reduces the deviation of the artificial leather during the rolling process, and reduces the rebound force of the artificial leather after rolling up through the friction between the convex strip 3 and the inner wall of the strip groove 2.

[0021] The roller 6 is located at the outside of the artificial leather body 1. During the rolling process of the artificial leather body 1, the roller 6 is always in contact with the outside of the artificial leather body 1. As the outer diameter of the cylinder formed after the artificial leather body 1 is rolled up gradually increases, the length of the support frame 5 connected to the roller 6 is also gradually getting longer, and the elastic potential energy accumulated in the support frame 5 is also increasing. When the artificial leather body 1 is completely rolled up, the limiting work of the gear ring 7 is released by the clamp 8, so that the support frame 5 can rotate relative to the support frame 4, thereby facilitating the movement of the roller 6 to the end close to the artificial leather body 1, so that the artificial leather body 1 roughly forms a cylinder, and the roller 6 can also reduce the rebound of the artificial leather body 1 after rolling up; after the roller 6 determines the position, the support frame 5 is limited by the clamp 8, so that the support frame 5 is in a stationary state relative to the support frame 4, thereby completing the rolling limit of the artificial leather body 1.

[0022] See also Figure 1 In order to improve the neatness of the rolling process of the artificial leather body 1, there are two strip grooves 2, which are respectively located on both sides of the artificial leather body 1, and there are two convex strips 3, which are respectively located on both sides of the artificial leather body 1. Through the two convex strips 3 and the two strip grooves 2, during the rolling process of the artificial leather body 1, the two convex strips 3 are respectively pressed into the corresponding strip grooves 2, and the rolling of the artificial leather body 1 is limited from both sides of the artificial leather body 1, so as to reduce the occurrence of the deviation of the rolling of the artificial leather body 1.

[0023] See also Figure 2 and Figure 5 The roller 6 is rotatably connected to the support frame 5. Therefore, the friction between the roller 6 and the artificial leather body 1 is rolling friction, which reduces the wear of the shaft roller on the surface of the artificial leather body 1 relative to the sliding friction.

[0024] The clamping member 8 includes a connecting rod 9 slidably arranged on the carrier 4, a circular groove 10 for inserting the connecting rod 9 is provided on the carrier 4, and the support frame 5 is rotatably mounted on the connecting rod 9, and one end of the connecting rod 9 away from the circular groove 10 is fixedly connected to the clamping member 8, and a locking member 11 for limiting the rotation of the connecting rod 9 is arranged in the circular groove 10. Through the locking member 11, the connecting rod 9 can only move along the axis of the connecting rod 9. When it is necessary to drive the support frame 5 to rotate relative to the carrier 4, the connecting rod 9 gradually pulls out of the circular groove 10, driving the clamping member 8 to separate from the gear ring 7, and then the support frame 5 can rotate relative to the carrier 4, thereby driving the roller 6 to roll on the rolled artificial leather body 1, and adjusting the position of the roller 6 according to the end position of the artificial leather body 1, so as to facilitate the fixing of the end of the artificial leather body 1 and reduce the rebound of the rolled artificial leather body 1.

[0025] See also Figure 5 The lock 11 includes a protrusion 111 fixedly mounted on the connecting rod 9, and a square groove 112 is provided on the inner wall of the circular groove 10 for the protrusion 111 to slide. The protrusion 111 is partially located in the square groove 112, and as the connecting rod 9 moves, the protrusion 111 is driven to slide in the square groove 112, wherein the rotation of the connecting rod 9 is restricted by the interaction force between the inner wall of the square groove 112 and the protrusion 111.

[0026] See also Figure 5 A spring 12 is provided in the circular groove 10 to drive the connecting rod 9 to slide into the circular groove 10. After the connecting rod 9 gradually moves out of the circular groove 10, if the connecting rod 9 is no longer subjected to force, the connecting rod 9 will shrink into the circular groove 10 under the elastic force of the spring 12. At the same time, the spring 12 can reduce the situation where the connecting rod 9 slides out of the circular groove 10 on its own.

[0027] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
