Description

Technical Field

[0001] This utility model relates to a paper shredder, and more particularly to a paper shredder with a switch protection mechanism. Background Technology

[0002] Traditional paper shredders have exposed power switches without any protection. The switch can be pressed directly without any obstruction, making it easy to power on the machine. This poses a safety hazard.

[0003] like Figure 1 As shown, the traditional paper shredder button switch 100 is completely unobstructed, allowing children to easily press it directly to power up the entire paper shredder and put it into standby mode. If children continue to touch other parts of the paper shredder afterward, there is a risk of injury. Utility Model Content

[0004] The purpose of this invention is to provide a paper shredder with a switch protection mechanism, and the technical problem to be solved is to improve the safety of the paper shredder.

[0005] To solve the above problems, the present invention adopts the following technical solution: a paper shredder with a switch protection mechanism, including a paper shredder body, a push-button switch on the paper shredder body, and a rotatable protection mechanism on the push-button switch. When the protection mechanism is closed, the push-button switch is blocked; when the protection mechanism is open, the push-button switch is exposed.

[0006] Furthermore, the protection mechanism includes at least two fan blades, a base, and a cap. The cap is rotatably snapped onto the base. The fan blades are disposed between the base and the cap. Both the cap and the base are annular, having through holes that expose the push-button switch. The cap has a first guide groove, and the base has a second guide groove. Guide posts are provided at the upper and lower ends of the fan blades, respectively. The guide posts at both ends of the fan blades are placed in the first guide groove and the second guide groove, so that the fan blades can slide between the cap and the base. A perforated hole is provided at the inner hole of the cap, so that the fan blades can extend out of the perforated hole and slide toward the center of the inner hole of the base, thereby sealing the inner hole of the base.

[0007] Furthermore, the guide post opposite the second guide groove is a rectangular column.

[0008] Furthermore, the number of fan blades is an even number of four or more.

[0009] Furthermore, the number of fan blades is six.

[0010] Furthermore, the second guide groove surrounds the outer perimeter of the inner hole of the base.

[0011] Furthermore, the second guide groove is a rectangular groove.

[0012] Furthermore, the first guide groove is distributed outside the inner hole of the cap, and the length direction of the first guide groove is deviated from the center of the inner hole of the cap, and is distributed in a rotating radial pattern.

[0013] Furthermore, the first guide groove is an oblong groove.

[0014] Compared with the prior art, this utility model improves the safety of the paper shredder by setting a rotatable protective mechanism on the button switch. When the switch protection mechanism is closed, the button switch is blocked; when the switch protection mechanism is open, the button switch is exposed. This prevents accidental operation from causing the paper shredder to enter standby mode while powered on by blocking the button switch when not in use. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0025] like Figure 2 and Figure 3As shown, this utility model discloses a paper shredder with a switch protection mechanism, including a paper shredder body 1 with a push-button switch 2. The push-button switch 2 is provided with a protection mechanism, which is opened by rotation. When the protection mechanism is closed, the push-button switch 2 is blocked and cannot be pressed. When the protection mechanism is rotated open, the push-button switch 2 is exposed and can be pressed to power on the paper shredder and put it into standby mode.

[0026] like Figure 3 and Figure 7 As shown, the protective mechanism is implemented by the following structure. The protective mechanism adopts an iris structure, similar to the arrangement of camera aperture blades. Specifically, it includes six fan blades 3, a base 4, and a screw cap 5. The fan blades 3 are triangular. In each fan blade 3, one edge abuts against the edge of the adjacent fan blade 3 on one side, and the other edge abuts against the edge of the adjacent fan blade 3 on the other side, so that two adjacent edges of each fan blade 3 abut against one edge of the fan blades 3 on the adjacent two sides. To be precise, as shown... Figure 5 As shown, each fan blade 3 is defined with three edges: a first edge 31, a second edge 32, and a third edge 33. The first edge 31 has the longest length and faces the center of the protection mechanism. Figure 3 As can be seen, the first edge 31 of fan blade 3A contacts and abuts against the third edge 33 of the adjacent fan blade 3B, the third edge 33 of fan blade 3A contacts and abuts against the first edge 31 of the adjacent fan blade 3C, and so on. Thus, the contraction or opening state is completed through the interaction of each edge. Figure 7 A schematic diagram after shrinkage is shown.

[0027] like Figure 3 As shown, both the screw cap 5 and the base 4 are annular. The screw cap 5 can be an annular cover with an internal cavity 51, allowing the fan blade 3 to be retracted. The length of the inner wall of the screw cap 5 is shorter than the length of the outer wall, forming a perforated hole 9 for the fan blade 3 to extend out. Figure 4 As shown, a first guide groove 6 is provided on the inner top wall of the cap 5. The first guide groove 6 is a straight, waist-shaped hole, and its length direction is offset from the center of the inner hole of the cap 5, and it is distributed in a rotating radial pattern. It can also be understood that the extended line of the plane where the first guide groove 6 is located intersects the circular projection of the inner hole of the cap 5 onto the plane, but does not pass through the center of the circle. The number of first guide grooves 6 is the same as the number of fan blades 3. Figure 3 As shown, a second guide groove 7 is provided around the inner hole of the bottom cover 4. The second guide groove 7 encloses the inner hole of the bottom cover 4 to form a polygon. The second guide groove 7 is a rectangular groove, and the number of second guide grooves 7 is the same as the number of fan blades 3. Figure 3 As can be seen, the polygon enclosed by the second guide groove 7 is a regular hexagon.

[0028] like Figure 5 and Figure 6 As shown, in order to cooperate with the use of the first guide groove 6 and the second guide groove 7, guide posts 8 are respectively provided on the two end surfaces of the fan blade 3 at the angle between the first edge 31 and the second edge 32. The two guide posts 8 are respectively placed in the corresponding first guide groove 6 and second guide groove 7. The guide post 8 opposite to the first guide groove 6 is a cylinder, and the guide post 8 opposite to the second guide groove 7 is a rectangular prism, or a cuboid, so as to limit the rotation of the fan blade 3, so that it cannot rotate and can only slide along the direction of the guide groove toward the center of the inner hole of the base 4.

[0029] like Figure 5 As shown, the included angle between the first edge 31 and the second edge 32 is formed by a right-angled side 34, and one of the right-angled sides of the guide post 8 of the rectangular column is aligned with it. That is, the two sides of the right-angled side 34 of the fan blade are respectively set parallel to the right-angled side of the guide post 8 of the rectangular column.

[0030] In this utility model, the cap 5 and the base 4 are rotatably connected as one unit by a snap-fit. Specifically, the inner diameter of the outer ring of the cap 5 is larger than the outer edge diameter of the base 4. A buckle is provided on the outer ring wall. The cap 5 is rotatably snapped to the base 4 by the ring buckle. The base 4 can be fixed to the shredder body 1 by screws or adhesive.

[0031] During assembly, six fan blades 3 are arranged sequentially on the base 5. The guide post 8 with a rectangular column on one side of the fan blade 3 is installed in the second guide groove 7 on the base 5. Then, the rotating cover 3 is pressed down on the fan blade 3 to ensure that the cylindrical guide post 8 on one side of the six fan blades 3 is installed in the first guide groove 6 on the rotating cover 3 and clamped to complete the assembly.

[0032] When the protection mechanism is closed, press Figure 9 As shown, hold the circumference of the cap 5 and rotate it about 45 degrees in the direction of the arrow (OPEN) marked on the cap 5 until it is blocked and cannot be rotated further. The principle is that when the cap 5 is rotated, the first guide groove 6 on the cap 5 drives the cylindrical guide post 8 on the fan blade 3 to slide in the first guide groove 6 on the cap 5. At the same time, the rectangular guide post 8 on the other side of the fan blade 3 slides in the second guide groove 7 on the base 4. From one end of the second guide groove 7 on the base 3 to the other end, that is, the six fan blades 3 move to the periphery, thus exposing the hexagonal through hole 10. Figure 6 As shown in the figure, the button switch 2 can be pressed through the hexagonal through hole 10.

[0033] When the protection mechanism is in the open state, the usage method is as follows: Figure 6As shown, hold the perimeter of the cap 5 and rotate it about 45 degrees in the direction of the arrow (CLOSE) marked on the cap 5 until there is resistance and you can no longer rotate it by force. The principle is that when the cap 5 is rotated, the first guide groove 6 on the cap 5 drives the cylindrical guide post 8 on the fan blade 3 to slide in the first guide groove 6 on the cap 5. At the same time, the rectangular column guide post 8 on the other side of the fan blade 3 slides in the second guide groove 7 on the base 4. From one end of the second guide groove 7 on the base 4 to the other end, that is, the six fan blades 4 move towards the center of the base 4, so that the fan blades 3 are gathered together and the middle is closed (state 11). Figure 9 As shown in the figure, this can prevent random touching of button switch 2.

[0034] This invention features a protective mechanism that controls the opening and closing of rotation to prevent accidental contact with the button switch 2, thereby protecting against potential risks and improving the safety of the paper shredder.
