The dustproof strap 40 can define a length direction, and the slider body 20 can be along The length direction is linearly moved. Further, the slider body 20 can have two convex walls 22 and a bottom portion 23. The two convex walls 22 and the bottom portion 23 and the upper cover member 30 can be configured to form a space for insertion. The dust-proof belt body 40 is disposed between the two convex walls 22 through the wearing space 50. The dust-proof belt body 40 defines a first side surface 41 facing away from the sliding seat body 20 and a sliding surface The second side 42 of the seat body 20, and the second side 42 and the bottom portion 23 abut each other in a relatively slidable manner.

Further, in the embodiment, the upper cover member 30 can be respectively recessed with a recess 33 along the opposite ends of the length of the dustproof strap 40, and the two magnet members 32 are respectively embedded in the two The groove 33, more specifically, the two magnet members 32 are disposed across the portion of the upper cover member 30 and the carriage body 20 across the length of the dust band 40.

The magnet members 32 and the magnetic pole portions 60 are disposed opposite to each other with the same magnetic poles. More specifically, the magnet members 32 and the magnetic pole portions 60 are magnetically repelled from each other (for example, the magnet members 32 and the magnet member 32 are The magnetic pole portions 60 have the same N pole or S pole and are disposed opposite to each other to make the dustproof strip body 40 Normally away from the upper cover member 30 and abutting against the slider body 20, it is worth mentioning that the magnetic strip member 40 and the magnetic pole portion 60 are mutually magnetically mutually exclusive, so that the dustproof strip body 40 can be smoothly received. The dust-proof belt body 40 and the bottom portion 23 are adhered to the bottom portion 23 of the slider body 20, so as to prevent impurities such as dust, debris and the like from entering the sliding slot 11 in the working environment, thereby affecting the linear mode. The function and operation of the group 1 can avoid the friction loss of the magnet member 32 and the magnetic pole portion 60, and has stable and good use quality.

In the actual use, the bottom portion 23 further includes a convex portion 231 and two inclined surfaces 232 extending obliquely toward the sliding groove 11 in opposite directions, and the two inclined surfaces 232 are opposite to the convex portion 231. Symmetrically, the two inclined surfaces 232 and the convex portion 231 can abut the dustproof strip body 40. Further, the convex portion 231 and the two inclined surfaces 232 can respectively contain a Teflon material, which can be respectively added. The wear resistance and lubricity of the convex portion 231 and the two inclined surfaces 232 can reduce the friction between the dustproof strip 40 and the bottom portion 23 to increase the relative sliding between the dustproof strip 40 and the bottom portion 23. In the smoothness of the time, the two inclined surfaces 232 can be easily adhered to the dust-proof belt body 40, and the smoothness of the dust-proof belt body 40 and the bottom portion 23 can be increased, and the dust dust can be further prevented from entering. This chute 11 causes pollution.

The dustproof strip body 40 is flexible and has a fixing portion 43 at the opposite ends. The two fixing portions 43 are respectively fixed at two ends of the opening 12, and the dustproof strip body 40 can be connected to the opening 12 Further, each of the fixing portions 43 can include at least two screws 431, and the two ends of the dustproof strap 40 can be locked to the periphery of the opening 12 through the screws 431. The periphery of the opening 12 can have a second edge 121. The slider body 20 can be moved along the two ends 121. The two ends 121 can be respectively provided with a magnetic member 122. The two magnetic members 122 can be respectively provided. Magnetizing with the magnetic pole portion 60, respectively, and further fitting the dustproof strip 40 to the open port The periphery of 12 can prevent dust and debris from entering the chute 11 and affect the function of use. The upper cover member 30 can have a peripheral wall 34. One end of the peripheral wall 34 can extend toward the dustproof strip body 40 and can have a predetermined gap with the dustproof strip body 40. The magnet member 32 and the peripheral wall 34 are mutually opposite each other. Adjacently disposed, the peripheral wall 34 prevents dust particles from entering the upper cover member 30, thereby avoiding the stability of magnetic mutual exclusion between the magnet member 32 and the magnetic pole portion 60.

In a second embodiment as shown in FIG. 6 , different from the above embodiment, the dustproof strap body 40a can have opposite sides, and the two sides face the upper cover member 30 and the slider body 20 respectively. The magnetic flux portions 60a and 60b are respectively disposed on the two side surfaces to increase the magnetic attraction effect of the dustproof strip body 40a and the magnetic member 122, and to increase the bonding effect between the dustproof strip body 40a and the open port.

In a third embodiment as shown in FIG. 7, different from the above embodiment, a spacer 70 is disposed between the upper cover member 30 and the dustproof strap 40, and the spacer 70 is adjacently disposed. On one side of the magnetic pole portion 60, the spacer 70 can isolate the upper cover member 30 and the magnetic pole portion 60, thereby preventing the upper cover member 30 and the magnetic pole portion 60 from abrading each other, thereby improving durability.
