Description

Fully dust-proof linear slide device

The present invention relates to a linear sliding device, and more particularly to a linear sliding device that is slidably disposed on a linear slide for carrying other objects.

As shown in the first and second figures, the linear slide device 10 (linear slider) currently applied to the linear slide 20 is generally composed of a body 101, two circulators 102, a plurality of rollers 103, and a dust cover 104. The composition is rolled by the roller 103 in the track of the base 101 and the two-end circulator 102, so that the linear slide device 10 can smoothly move on the linear slide 20. The dust cover 104 is usually coupled to the end of the circulator 102 to form an end dustproof structure of the linear sliding device 10. The dust cover 104 is formed with a 凸-shaped convex edge 1041 matching the outer shape of the linear slide rail 20, and the convex edge 1041 is used for a straight line. When the slide device 10 moves on the linear slide rail 20, the processed dust or foreign matter falling on the surface of the linear slide rail 20 is scraped off to prevent it from being caught in the running area of the roller 103 on the linear slide rail 20, which interferes with the roller. The smooth rolling of the 103 under high-speed motion causes the linear slide device 10 to fail.

However, the machining dust or foreign matter may invade from the bottom end surface of the linear sliding device 10 or the screw hole 201 on the upper surface of the linear sliding rail 20 in addition to the intrusion of the linear sliding device 10 in the direction in which the linear sliding device 10 travels. The edge invades the running area of the roller 103 to the linear slide 20. To this end, the conventional linear sliding device 10 has various types of dust-proof and dust-proof structures, which are respectively disposed at the bottom of the base 101 and the upper end of the rail groove 1011 of the base 101, for example, as shown in Chinese Patent Publications CN101612625, CN101025197, CN201241917, CN103883620, and the United States. Various conventional dustproof structures disclosed in the patent publications US Pat. No. 4,918,846, US Pat. No. 4, 092, 095, US Pat. No. 5, 001, 1300, US Pat. No. 5, 527, 549, US Pat. No. 5, 594, 720, US Pat.

As shown in the third figure, the upper dust-proof structure is formed by using a stamped iron piece 105, and the two dust-proof strips 106 are joined to the two sides or the bottom surface of the iron piece 105 to lock the iron piece 105 to the seat body 101. Above the rail groove 1011, or the iron piece 105 is disposed on the rail groove 1011, and then the two ends are locked or engaged in the two circulators 102, so that the two dustproof strips 106 abut against the top surface of the linear slide rail 20, To prevent dust and foreign matter from being caught in the roller 103. However, the design of the above dust-proof structure is equivalent to opening a stamping die for punching out the iron piece 105, and opening a plastic injection die for injecting the dust-proof strip 106 into the iron piece 105, so that the manufacturing cost thereof will be special. expensive. Moreover, the iron piece 105 must be locked or engaged at a predetermined position, resulting in a cumbersome assembly process, affecting assembly cost and production efficiency.
