Description

Technical Field

[0001] This utility model belongs to the field of paper shredder technology, and in particular relates to a paper shredder with a protective structure. Background Technology

[0002] A paper shredder is an office appliance used to cut paper into small pieces to protect sensitive information from being leaked. It typically features automatic paper feeding, continuous shredding, and overload protection, making it suitable for both business and home security needs.

[0003] The process of shredding paper requires the use of a paper shredder. The problem with the above technology is that the existing paper shredder requires paper to be put in through the feed port. However, in order to ensure the stability of the paper shredding, it is necessary to hold the paper down by hand to prevent the paper from wrinkling or being shredded incompletely, which could cause jamming. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a paper shredder with a protective structure that can overcome or at least partially solve the above problems.

[0005] This utility model is implemented as follows: a paper shredder with a protective structure includes a paper shredder housing, the top of which has an inlet, a sliding plate on the top of which has a sliding groove, a sliding block in the inner cavity of which has a sliding block, a locking plate fixedly connected to the top of which has a limit component on the top of which has a locking component on one side.

[0006] The limiting component is used to limit and support the paper;

[0007] The locking assembly is used to fix the position of the locking plate.

[0008] Preferably, the limiting component includes a movable frame, a movable block is sleeved on the surface of the movable frame, an adjusting block is fixedly connected to one side of the movable block, a limiting plate is provided on the top of the adjusting block, a limiting groove is formed on the top of the limiting plate, and a limiting rod is provided in the inner cavity of the limiting groove.

[0009] Preferably, the inner cavity of the locking plate is provided with a locking rod, the top of the locking rod is fixedly connected to a locking block, and the bottom of the locking block is fixedly connected to a tension spring.

[0010] Preferably, the bottom of the sliding plate is fixedly connected to the shredder housing, and the top of the shredder housing is provided with a locking groove.

[0011] Preferably, the bottom of the movable frame is fixedly connected to the movable frame, and the inner wall of the movable block is in contact with the movable frame.

[0012] Preferably, the surface of the limiting rod contacts the inner wall of the limiting groove, and the moving block can be connected to the moving frame by bolts.

[0013] Preferably, the side of the locking rod closest to the inner wall of the locking groove contacts the inner wall of the locking groove, and the bottom of the tension spring is fixedly connected to the locking plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes a combination of a limiting component and a locking component. Pulling the locking block upwards causes it to move the locking rod and stretch the tension spring. The locking rod then leaves the inner cavity of the locking groove. Pulling the sliding block allows it to slide within the inner cavity of the sliding groove until it reaches the desired size for shredded paper. Releasing the locking block then releases the tension spring, causing the locking rod to reset. Pulling the moving block to the desired height allows it to be released. The moving block is filled with an elastic material and automatically positions itself at the desired location. This invention solves the problem in existing paper shredders where paper needs to be fed through an inlet, but to ensure stable shredding, the paper must be manually supported to prevent wrinkles or incomplete shredding, which can lead to jamming.

[0021] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0022] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 4 As shown in the figure, the present invention provides a paper shredder with a protective structure, including a paper shredder housing 1, a feeding port 2 on the top of the paper shredder housing 1, a sliding plate 3 on the top of the paper shredder housing, a sliding groove 4 on the top of the sliding plate 3, a sliding block 5 in the inner cavity of the sliding groove 4, a locking plate 6 fixedly connected to the top of the sliding block 5, a limit component 7 on the top of the locking plate 6, and a locking component 8 on one side of the locking plate 6;

[0024] The limiting component 7 is used to limit and support the paper;

[0025] The locking assembly 8 is used to fix the position of the locking plate 6.

[0026] The limiting component 7 includes a movable frame 701, a movable block 702 is sleeved on the surface of the movable frame 701, an adjusting block 703 is fixedly connected to one side of the movable block 702, a limiting plate 704 is provided on the top of the adjusting block 703, a limiting groove 705 is opened on the top of the limiting plate 704, and a limiting rod 706 is provided in the inner cavity of the limiting groove 705.

[0027] The inner cavity of the locking plate 6 is provided with a locking rod 801, the top of the locking rod 801 is fixedly connected to a locking block 802, and the bottom of the locking block 802 is fixedly connected to a tension spring 803.

[0028] The bottom of the sliding plate 3 is fixedly connected to the shredder housing 1, and a locking groove is provided on the top of the shredder housing 1.

[0029] The bottom of the movable frame 701 is fixedly connected to the movable frame 701, and the inner wall of the movable block 702 is in contact with the movable frame 701.

[0030] The surface of the limiting rod 706 contacts the inner wall of the limiting groove 705, and the moving block 702 can be connected to the moving frame 701 by bolts.

[0031] The side of the locking rod 801 closest to the inner wall of the locking groove contacts the inner wall of the locking groove, and the bottom of the tension spring 803 is fixedly connected to the locking plate 6.

[0032] The working principle of this utility model:

[0033] In use, pull the locking block 802 upwards. The locking block 802 moves the locking rod 801 and stretches the tension spring 803. The locking rod 801 leaves the inner cavity of the locking groove. Pull the sliding block 5. The sliding block 5 slides in the inner cavity of the sliding groove 4. After moving to the size corresponding to the required shredded paper, release the locking block 802. The force released after the tension spring 803 is stretched causes the locking rod 801 to return to its original position. Pull the moving block 702 to move it to the required height and then release it. The moving block 702 is filled with elastic material and will automatically position itself in the moving position after moving. When it is necessary to adjust the position of the limiting plate 704, simply loosen the limiting sleeve on the limiting rod 706, then pull the limiting plate 704 to move it, and then reset the limiting sleeve to fix the limiting rod 706.
