Description

Technical Field

[0001] The utility model belongs to the technical field of linear guide rails, and particularly relates to an end sealing device for a linear guide rail. Background Art

[0002] A linear guide rail (linear slider), also known as a linear rail, slide rail, linear guide, or linear slide, can be divided into three types: roller linear guide rails, cylindrical linear guide rails, and ball linear guide rails. The end cover of a linear guide rail is a component in the linear guide rail system and is used to seal both ends of the linear guide rail.

[0003] For example, an end sealing cover for a linear guide rail with a publication number of CN 207480064 U includes a sealing end cover body formed by one-time injection molding. A linear guide rail through hole is opened in the middle of the lower end of the sealing end cover body, and a sealing rubber ring is pasted on the inner edge surface of the linear guide rail through hole. The outer edge of the sealing rubber ring protrudes inward from the inner surface of the sealing end cover body. The sealing end cover body also has upper fixing holes and lower fixing holes. A reinforcing base is provided in the upper fixing hole, an inclined receiving platform is provided in the lower fixing hole, a clamping interface is provided between the upper fixing hole and the lower fixing hole, and positioning columns are provided inside the clamping interface. The beneficial effects are that through injection molding, the processing process is simplified, which is conducive to environmental protection, and it can be tightly connected to the base and the guide rail, preventing dust and oil from entering, and improving the accuracy of automated production and processing.

[0004] This sealing device is a plastic part, and its protection effect against external impact is poor. At the same time, its sealing rubber ring is located on the inner wall of the sealing device, and it is not easy to repair after it is damaged. To solve the above problems, an end sealing device for a linear guide rail is proposed. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an end sealing device for a linear guide rail to solve the above problems, including:

[0007] A rubber sealing block, which is embedded and connected inside the second installation groove;

[0008] A protective cover plate, which is fixedly installed inside the first installation groove by bolts.

[0009] Through the above technical solution, by fixedly installing the sealing end cover at both ends of the linear guide rail, since the rubber sealing block is installed inside the second installation groove on the front side of the sealing end cover, it can prevent dust and oil from entering the slide seat. By fixedly installing the protective cover plate inside the first installation groove, on the one hand, the rubber sealing block can be clamped between the sealing end cover and the protective cover plate through the protective cover plate to improve the stability of the rubber sealing block. On the other hand, the protective cover plate can resist the external impact force received by the linear guide rail. At the same time, when the sealing block needs to be replaced, the protective cover plate can be removed for quick replacement.

[0010] In a preferred embodiment, convex platforms are integrally provided on both the left and right sides inside the second installation groove, and limiting holes adapted to the convex platforms are provided on both the left and right sides of the rubber sealing block.

[0011] Through the above technical solution, the rubber sealing block can be quickly installed by the cooperation of the convex platform and the limiting hole.

[0012] In a preferred embodiment, a plurality of first threaded holes are provided on both the left and right sides of the first installation groove, a plurality of second threaded holes are provided on both the left and right sides of the protective cover plate, and the positions and numbers of the first threaded holes and the second threaded holes are the same.

[0013] Through the above technical solution, the protective cover plate and the sealing end cover are threadedly connected by bolts in cooperation with the first threaded holes and the second threaded holes.

[0014] In a preferred embodiment, a plurality of installation grooves are provided on the back of the sealing end cover, and contact pads are embedded inside the installation grooves.

[0015] Through the above technical solution, by providing the contact pads, on the one hand, the wear at the connection between the sealing end cover and the linear guide rail is reduced, and on the other hand, the connection between the sealing end cover and the linear guide rail is sealed.

[0016] In a preferred embodiment, the protective cover plate is formed by casting high manganese steel, and the outer extension part of the rubber sealing block and the protective cover plate protrudes from the lower surface of the protective cover plate after connection.

[0017] Through the above technical solution, when the rubber sealing block and the protective cover plate are installed, the rubber sealing block is in direct contact with the slide seat.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effect of the present utility model is: The present utility model provides a sealing device for the end of a linear guide rail.

[0019] By fixedly installing the sealed end cover at both ends of the linear guide rail, since a rubber sealing block is installed inside the second installation groove on the front side of the sealed end cover, it can prevent dust and oil from entering the sliding seat. By fixedly installing the protective cover plate inside the first installation groove, on the one hand, the rubber sealing block can be clamped between the sealed end cover and the protective cover plate through the protective cover plate to improve the stability of the rubber sealing block. On the other hand, the external impact force received by the linear guide rail can be resisted by the protective cover plate. At the same time, when the sealing block needs to be replaced, the protective cover plate can be removed for quick replacement. BRIEF DESCRIPTION OF THE DRAWINGS
