[0002] Before being made into furniture, wood needs to be cut and sanded, and then wrapped in plastic film to protect the wood surface from scratches, stains and moisture.

[0003] Traditionally, plastic film is stored by placing rolls directly on the ground or on simple shelves. This method not only takes up a lot of space, but also makes it inconvenient to retrieve wide plastic films when placed on the ground, and it is also inconvenient to retrieve rolls when placed on simple shelves.

[0004] Therefore, this application provides a shelf for holding plastic film. Utility Model Content

[0005] In view of the shortcomings of the prior art, this application provides a rack for storing plastic film, which overcomes the shortcomings of the prior art and aims to solve the problem that the traditional way of storing plastic film usually involves placing the plastic film rolls directly on the ground or on a simple rack. This method not only occupies a lot of space, but also makes it inconvenient to take out the plastic film when it is placed on the ground, especially for wide plastic films. Placing it on a simple rack also makes it inconvenient to take out and put out the plastic film rolls.

[0006] To achieve the above objectives, this application provides the following technical solution: a frame for holding plastic film, comprising two sets of frame bodies arranged opposite to each other. A bracket is fixedly installed at the top of each frame body, and a connecting frame is fixedly installed at the top of each bracket. A slot is provided at the top of each connecting frame. An installation shaft is engaged with the top of each of the two sets of connecting frames at the slot. A roll of plastic film is arranged between the two sets of connecting frames, and the installation shaft passes through the roll of plastic film. A hinge seat is provided on one side of the slot at the top of each connecting frame, and a limit buckle is hinged to the top of the hinge seat. Two sets of supports are provided on the other side of the slot at the top of each connecting frame, and a fixing pin connects the two sets of supports to the limit buckle. Through holes are provided inside both the limit buckle and the two sets of supports.

[0007] By adopting the above technical solution, the mounting shaft is passed through the middle of the plastic film roll, and both ends of the mounting shaft are locked in two sets of slots.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Reference Figure 1-4 A frame for holding plastic film includes two sets of frame bodies 1, which are arranged opposite each other. A bracket 2 is fixedly installed at the top of the frame body 1, and a connecting frame 3 is fixedly installed at the top of the bracket 2. The top of the connecting frame 3 has a slot 4. The top of the two sets of connecting frames 3 is engaged with the mounting shaft 5 at the slot 4. A plastic film roll 6 is arranged between the two sets of connecting frames 3. The mounting shaft 5 passes through the plastic film roll 6. A hinge seat 8 is arranged on one side of the top of the connecting frame 3 at the slot 4. A limit buckle 9 is hinged to the top of the hinge seat 8. Two sets of supports 10 are arranged on the other side of the top of the connecting frame 3 at the slot 4. A fixing pin 11 connects the two sets of supports 10 and the limit buckle 9. The limit buckle 9 and the two sets of supports 10 are all provided with through holes 13. Two sets of limit blocks 12 are fixedly installed on the outer surface of the mounting shaft 5. The two sets of limit blocks 12 are located on both sides of one set of connecting frames 3.

[0032] The mounting shaft 5 is passed through the middle of the plastic film roll 6, and both ends of the mounting shaft 5 are secured in the two sets of slots 4. Then, the two sets of limiting buckles 9 are rotated respectively, so that the through holes 13 of the limiting buckles 9 correspond to the through holes 13 of the two sets of supports 10. The fixing pin 11 is passed through the through holes 13 to fix the limiting buckles 9 between the two sets of supports 10, thus completing the limitation of the plastic film roll 6. The plastic film roll 6 can then be rotated to package wood, etc. The same principle applies when replacing the plastic film roll 6. The fixing pin 11 is removed to separate the limiting buckles 9 from the two sets of supports 10. Rotating the limiting buckles 9 releases the restriction on the mounting shaft 5, and the mounting shaft 5 can be removed to replace the plastic film roll 6. This is beneficial for users to place the plastic film roll 6 and to quickly install and remove the plastic film roll 6. The two sets of limiting blocks 12 limit the position of the mounting shaft 5, thereby improving the stability of the mounting shaft 5 in the slots 4.

[0033] Reference Figure 1-3 A rectangular plate 16 is provided between the two sets of frame bodies 1 and below the plastic film roll 6. Two sets of rotating seats 17 are fixedly installed on the top of the rectangular plate 16. The two sets of rotating seats 17 are arranged opposite to each other, and an auxiliary roller 18 is rotatably connected between the two sets of rotating seats 17. One end of the fixing pin 11 is provided with a thread 15, and the fixing pin 11 is threadedly connected to a set of supports 10.

[0034] The auxiliary roller 18 provides additional support when the plastic film roll 6 is released. At the same time, the auxiliary roller 18 is rotatably connected to two sets of rotating seats 17, so that the auxiliary roller 18 rotates in conjunction with the plastic film roll 6 when it is released. When the auxiliary roller 18 rotates, it guides the rectangular plate 16, which helps to improve the flatness of the plastic film roll 6 after it is unfolded. After the fixing pin 11 passes through a set of supports 10 and limit buckle 9 in sequence, the fixing pin 11 is rotated so that the fixing pin 11 is threadedly connected to another set of supports 10 through the thread 15, which prevents the fixing pin 11 from loosening or falling off during operation and improves the stability of the fixing pin 11 after installation.

[0035] Reference Figure 1-3 A base plate 19 is fixedly installed between the two sets of frame bodies 1. Several sets of springs 20 are installed on the top of the base plate 19, and the top of the sets of springs 20 are installed on the bottom of the rectangular plate 16. Weighted feet 22 are fixedly installed at the four corners of the bottom of the frame body 1. The rectangular plate 16 and the auxiliary roller 18 can move under the elastic action of the sets of springs 20, so that the auxiliary roller 18 can always be in contact with the bottom of the mounting shaft 5 as the diameter of the mounting shaft 5 changes. This is beneficial for the auxiliary roller 18 to automatically adjust its height according to the change of the diameter of the mounting shaft 5 under the elastic action of the sets of springs 20. The four sets of weighted feet 22 improve the stability of the frame body 1 and minimize the possibility of the frame body 1 tilting or collapsing.

[0036] Referring to 2-41, a telescopic guide rod 21 is provided inside the spring 20. The bottom end of the telescopic guide rod 21 is installed on the top end of the base plate 19, and the telescopic end of the telescopic guide rod 21 is installed on the bottom end of the rectangular plate 16. A rotating cap 23 is fixedly installed on the end of the fixing pin 11 away from the thread 15. The telescopic guide rod 21 plays a guiding role when the spring 20 elastically expands and contracts, which helps to improve the service life of the spring 20. The rotating cap 23 provides a hand action point when rotating the fixing pin 11, which is convenient for loading and unloading the fixing pin 11.

[0037] Working principle: Pass the mounting shaft 5 through the middle of the plastic film roll 6, and lock both ends of the mounting shaft 5 into the two sets of slots 4. Then, rotate the two sets of limiting buckles 9 respectively, so that the through holes 13 of the limiting buckles 9 correspond to the through holes 13 of the two sets of supports 10. Pass the fixing pin 11 through the through holes 13 to fix the limiting buckles 9 between the two sets of supports 10, thus limiting the plastic film roll 6. The plastic film roll 6 can then be rotated to package wood, etc. The same principle applies when replacing the plastic film roll 6. Remove the fixing pin 11 to separate the limiting buckles 9 from the two sets of supports 10. Rotating the limit buckle 9 releases the restriction on the mounting shaft 5, allowing the mounting shaft 5 to be removed for replacement of the plastic film roll 6. This facilitates the user's placement of the plastic film roll 6 and allows for quick installation and removal of the plastic film roll 6. The auxiliary roller 18 provides additional support when the plastic film roll 6 is released. At the same time, the auxiliary roller 18 is rotatably connected to two sets of rotating seats 17, so that when the plastic film roll 6 is released, the auxiliary roller 18 rotates in conjunction with it. When the auxiliary roller 18 rotates, it guides the rectangular plate 16, which helps to improve the flatness of the plastic film roll 6 after it is unfolded.

[0038] Among them, the position of the mounting shaft 5 is restricted by two sets of limit blocks 12, which improves the stability of the mounting shaft 5 in the slot 4. After the fixing pin 11 passes through a set of supports 10 and limit buckles 9 in sequence, the fixing pin 11 is rotated so that the fixing pin 11 is threadedly connected to another set of supports 10 through the thread 15, which prevents the fixing pin 11 from loosening or falling off during operation and improves the stability of the fixing pin 11 after installation.

[0039] Meanwhile, the rectangular plate 16 and the auxiliary roller 18 can move under the elastic action of several sets of springs 20, so that the auxiliary roller 18 can always be in contact with the bottom of the mounting shaft 5 as the diameter of the mounting shaft 5 changes. This is beneficial for the auxiliary roller 18 to automatically adjust its height according to the diameter change of the mounting shaft 5 under the elastic action of several sets of springs 20. The telescopic guide rod 21 plays a guiding role when the spring 20 elastically extends and retracts, which helps to improve the service life of the spring 20.

[0040] In addition, the stability of the frame 1 is improved by the four sets of weighted feet 22, which can prevent the frame 1 from tilting or collapsing as much as possible; the rotating cap 23 provides a hand action point when rotating the fixing pin 11, which is convenient for loading and unloading the fixing pin 11.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
