Description of the Invention: [Technical Field] The present invention relates to a linear slide rail accessory, particularly a dustproof device for a linear slide rail, which uses an elastic hole to adjust the amount of interference between the dust guard and the slide rail. [Prior Art] Today's linear slides are widely used in industry. In addition to being a high-precision effect of linear feed transmission, other aspects have lower friction loss rate, high energy conversion rate, low noise and high rigidity. Therefore, the importance of linear slides for various industrial applications and tools today is beyond words. " The current-like linear slides are designed to prevent the intrusion of chips and dust into the interior of the slider, and the producers will add scraping oil on the ends of the linear sliding handles. The dust-proof effect is limited: in order to achieve the dust-proof effect of the receiving surface, many devices with high dust-proof effect have been developed, which are expected to prolong the life and the required requirements; θ, Y, and seven-seven people make Xiao and the county of the ages帛1 riding structure 'Please refer to the following description of the sun and the moon: The first picture is the US patent No. 5,769,543: a diagram of the dustproof "3 set - accommodation space, for = f piece 6 2, dustproof piece 6 3 By the direction of the door type, the direction of the holding force is directed to the direction of the sliding direction, and the interference amount of the two 1304860 piece 6 3 and the slippery, to prevent the chip and dust from invading the inside of the slider and affecting the operation of the slider; However, the following problems may occur after the application of the conventional technology: First, the door spring piece 6 2 is only installed on the side of the dustproof piece 63 3 , and the dust-proof piece 6 3 is not uniformly contacted with the sliding handle, so that it is dust-proof. The effect is obviously not obvious; _ Second, the dustproof device needs to make extra And the time and manpower required for the installation process are relatively improved. Nowadays, in order to obtain better dustproof effect, the industry developers have developed a dustproof device, which is the US patent No. 5,634,722, which is installed on both sides. Adjust the screw to adjust the interference between the dust-proof piece and the slide rail. When the adjustment screw is screwed into the center of the slide rail, the amount of interference of the dust-proof sheet with respect to the slipper is relatively increased. For example, if the amount of interference is reduced, the adjustment screw can be screwed out. The problems with this conventional design are as follows: First, because the adjusting screw is a point contact with the dustproof piece, the force of the dustproof piece is uneven, and the wear of the lip of the dustproof piece is inconsistent, such as adjusting the interference amount again. The interference amount of each part is also relatively uneven, which causes the life of the dustproof piece to be shortened and the dustproof effect is not good. Second, there are many dustproof fittings, and the installation time is complicated and the manpower is relatively increased. To solve the aforementioned related issues, the creators of the present invention are based on the research and development techniques and experience accumulated in the field of linear slippery in the past, and can The demand adjusts the degree of interference and adds research and development, and finally develops a new dust-proof device for linear sliding of 1304860. [Summary of the Invention] Based on the above-mentioned shortcomings of the conventional ball screw cooling device, the inventors have improved The present invention has the object of achieving the following objects.

The shape of the elastic hole is originally 1304080, but the shape is oval due to the absorption of the deformation amount. Therefore, the adjustment of the interference amount of the dustproof sheet of the present invention is adjusted by the application of the elastic deformation property of the material and the energy storage of the elastic hole, and the interference amount is adjusted in this way, since the elastic hole is evenly distributed on the dustproof sheet, The released energy not only distributes the interference amount evenly on the lip of the inner contour, but also the lip wear of the dustproof piece is relatively uniform; when the lip of the dustproof piece is worn due to wear, the dustproof effect is reduced, at this time, It is adjusted by the release of the energy stored in the elastic hole, so that the interference between the dustproof piece and the slide rail is restored to the original state, thereby restoring the optimal dustproof effect; Therefore, the material used for the dustproof sheet of the present invention is made of a porous material, and the space between the elastic hole and the positioning post is provided for oil (fat) storage, so the dustproof piece also provides a lubricating function to rub it. The relative resistance is reduced to prolong the life of the dustproof sheet, and has the function of preventing the lubricating oil (fat) from overflowing.
