The linear guide rail is used to support and guide the moving part to move reciprocatingly in a given direction.
[0003] A common linear guide pair is composed of a guide rail, a sliding block, a steel ball, a return device, a retainer, a sealing end cover and a baffle. The sealing cover is usually made of plastic or stainless steel and is installed at both ends of the return device through the sealing end cover to prevent dust and debris from entering the sliding block, thereby achieving the sealing and dust removal effect.
[0004] However, in the prior art, the sealing end cover has an integral structure. When the sealing end cover needs to be replaced due to damage, the removed damaged sealing end cover needs to be slid along the guide rail to one end of the guide rail to be removed. Similarly, the new sealing end cover also needs to be sleeved and slid to the return device from one end of the guide rail, and then the sealing end cover is fixed through bolts. In this way, when the end of the guide rail is blocked or multiple return devices are arranged on a single guide rail, the guide rail or other return devices need to be disassembled to replace the sealing end cover, which is extremely inconvenient. Therefore, the linear guide pair sealing dust removal structure is provided. UTILITY MODEL CONTENTS

[0007] After the two concave plates are horizontally turned by one hundred and eighty degrees and sleeved on the outside of the guide rail, the two concave plates are abutted to each other to match the overall trajectory of the two concave plates and the two side edge scraper pieces with the outer wall of the guide rail, so as to form a complete sealing end cover and the sealing end cover is sleeved and installed on the guide rail.
[0008] As a further scheme of the utility model, the thickness of the protruding end face of the side edge scraper piece matches the thickness of the concave plate.
[0009] As a further scheme of the utility model: one end of the concave plate is provided with a mounting hole penetrating through to the other end of the concave plate, four mounting holes are arranged, two of the four mounting holes form a group and are symmetrically distributed with the vertical center line of the concave plate as the center.
[0010] As a further scheme of the utility model: the inner wall width of the concave plate is greater than the width of the guide rail, the outer wall track of the side edge scraper piece matches the outer wall track of one side of the guide rail.
[0011] When the side edge scraper piece is attached to the side surface of the guide rail, the inner wall bottom of the concave plate is attached to the upper surface of the guide rail.
[0012] As a further scheme of the utility model: a C-shaped clamping groove is formed at the edge of one end of the concave plate, a C-shaped protrusion is formed at the side of the concave plate far away from the side edge scraper piece.
[0013] The C-shaped protrusion on one concave plate is clamped in the C-shaped clamping groove on the other concave plate, so as to realize horizontal and vertical limiting of the two concave plates.
[0014] Compared with the prior art, the utility model has the advantages that:
[0015] The sealing cover plate is composed of two groups of concave plates and side edge scraper pieces, so that the disassembly operation of the sealing cover plate can be operated above the guide rail, compared with the structure that the traditional integrated sealing cover plate is taken out from the end of the guide rail, the combined sealing cover plate is more convenient to disassemble and can effectively improve the maintenance efficiency of the sealing cover plate.
