Description

Technical Field

[0001] The utility model belongs to the technical field related to sandpaper, in particular to sandpaper that can prevent hands from being stabbed. Background Art

[0002] Sandpaper is a kind of paper with abrasive particles attached to it. It is used to smooth the surface of an object or remove attachments on the surface of an object. It is sometimes also used to increase friction. Sandpaper is divided into different numbers according to different degrees of roughness to suit different uses.

[0003] However, existing sandpaper has uneven and rough sidewalls, so if it is not shielded and protected, users may get hurt after prolonged use. Furthermore, protective structures installed on sandpaper are not easily removable, so if the sandpaper is damaged, the protective structures become unusable, resulting in increased costs and waste of resources. Therefore, we provide sandpaper that is resistant to hand injuries to address the aforementioned issues. Utility Model Content

[0004] The purpose of the utility model is to provide a sandpaper that can prevent hand punctures. The connecting piece and the protective ring piece protect the peripheral side of the sandpaper body to avoid punctures during operation. At the same time, the soft ring is turned over, folded and compressed to facilitate the disassembly of the connecting piece and the sandpaper body, so that the connecting piece can be reused.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model discloses a sandpaper for preventing hand puncture, comprising a sandpaper body; a connecting piece having the same shape and size as the sandpaper body is provided on the upper end surface of the sandpaper body; a protective ring piece is fixed on the lower end surface of the connecting piece, and the inner side of the protective ring piece is in contact with the peripheral side of the sandpaper body; a circular opening is provided in the middle of the connecting piece in an upper and lower penetrating manner; a movable ring is fixed on the upper end surface of the sandpaper body; and a soft ring is fixed on the upper end surface of the movable ring.

[0007] The utility model is further configured such that a plurality of positioning grooves are provided on the surface of the connecting piece and are vertically penetrated, and the plurality of positioning grooves are evenly distributed in a ring shape along the circumference of the connecting piece, and the center of the circular opening is consistent with the center position between the plurality of positioning grooves.

[0008] The utility model is further configured such that positioning blocks are fixed at positions on the upper end surface of the sandpaper body corresponding to the positioning grooves, and each positioning block is respectively inserted into a positioning groove corresponding to the position thereof.

[0009] The utility model is further configured such that a ring opening is provided in the middle of the upper surface of the connecting piece, the center point of which is consistent with the center position of the circular opening, and the diameter of the ring opening is larger than the diameter of the circular opening.

[0010] The utility model is further configured such that the movable ring is slidably inserted into the inner position of the circular opening, the soft ring is movable inside the ring opening, and the peripheral side of the soft ring is connected to the inner side surface of the ring opening.

[0011] The present invention is further configured such that the upper end surface of the connecting piece is provided with a plurality of notches which are all connected with the inside of the ring opening, and the plurality of notches are evenly distributed in a ring shape.

[0012] The present invention is further configured such that annular grooves are provided at positions of the circumferential side surfaces of the soft ring corresponding to the recesses, and the annular grooves are located at a middle height position of the circumferential side surfaces of the soft ring.

[0013] The utility model has the following beneficial effects:

[0014] 1. When the present invention is in use, the connecting piece is placed on the upper end surface of the sandpaper body, and the protective ring piece on the lower end surface of the connecting piece will be directly sleeved on the peripheral side of the sandpaper body. At this time, the protective ring piece will protect the peripheral side of the sandpaper body. When the staff uses the sandpaper, the protective ring piece will protect the contact part of the staff, preventing the rough parts of the peripheral side of the sandpaper body from piercing the staff's body parts.

[0015] 2. When the utility model is in use, the movable ring on the upper end surface of the sandpaper body is passed through the position of the circular opening, and the soft ring is connected to the upper end surface of the connecting piece. Thus, the soft ring can ensure the stability of the connection between the connecting piece and the sandpaper body without being affected by external forces. At the same time, the soft ring is turned over and folded, and can be taken out from the inside of the circular opening together with the movable ring, thereby facilitating the disassembly of the connecting piece and the sandpaper body.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the above advantages at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the protective ring piece 205 will protect the peripheral side of the sandpaper body 1, and then when the staff uses the sandpaper, the protective ring piece 205 will protect the contact part of the staff, so as to prevent the rough parts of the peripheral side of the sandpaper body 1 from piercing the body parts of the staff. After the connecting piece 2 is connected to the upper end surface of the sandpaper body 1, the movable ring 103 on the upper end surface of the sandpaper body 1 will pass through the position of the circular opening 201, and the soft ring 102 will be connected to the upper end surface of the connecting piece 2. Thus, the soft ring 102 can ensure the stability of the connection between the connecting piece 2 and the sandpaper body 1 without being affected by external force. At the same time, the soft ring 102 is turned over and folded, and can be taken out from the inside of the circular opening 201 together with the movable ring 103, so as to facilitate the disassembly of the connecting piece 2 and the sandpaper body 1.

[0030] Example 2

[0031] See also Figure 2 and Figure 3 On the basis of Example 1, the positioning block 101 and the positioning groove 204 are used in conjunction with each other to ensure that the connecting piece 2 and the sandpaper body 1 can rotate synchronously.

[0032] Specifically, a plurality of positioning grooves 204 are provided on the surface of the connecting piece 2 and are arranged to pass through the connecting piece 2 in an up-and-down manner, and the plurality of positioning grooves 204 are evenly distributed in a ring shape along the circumference of the connecting piece 2.
