Description

External sealing sheet structure and sliding seat assembly

The present invention relates to an external sealing sheet structure and a sliding seat assembly, in particular to a two-layer external sealing sheet having a scraping blade and a metal scraper, and a further hanging sealing sheet is coupled to the end of the rigid body of the sliding seat. The creation of the reinforcement sheet on the cover.

In order to prevent the chip and dust from entering the rigid body of the sliding seat, the linear sliding rail generally affects the stability of the rigid body on the sliding rail. Generally, a sealing piece is installed on both ends of the rigid body of the sliding seat, and at the same time, in order to avoid the grease leakage of the track, A scraper will be added. Among them, the oil scraper also has the effect of dustproof, and some linear slides use the oil scraper to achieve the effect of scraping oil and dust.

Wherein, the external sealing piece is a sealing piece or a scraping piece combined on the outermost side of the rigid body of the sliding seat; in the dustproof device of the linear sliding rail of the Republic of China Patent No. 200831796, the dustproof device comprises a fixing seat and a An oil scraping piece, the fixing seat corresponds to an end cover of a sliding body rigid body, the oil scraping piece corresponds to the fixing seat, and the oil scraping piece and the fixing seat are locked by the screw to the end cover, or further locked The slide is rigid. The design of the structure, the oil scraper will be exposed in the environment, when the rigid body of the sliding body is running or running on the sliding rail, the plastic material scraping piece may collide and cause damage; the scraping oil piece is screwed The fixing seat is locked on the end cover. When the sliding body is in a rigid body, the end cover is subjected to the impact force of the rolling element. Therefore, screwing the screw into the end cover may cause stress concentration, and the end cover is easily damaged. In addition, since the end cap is formed by resin molding, the stress of the screw locked on the resin is released with time, so that the fixing effect is deteriorated, and the scraping blade and the fixing seat are loosened; The screw is fixed on the rigid body of the sliding seat and occupies the space of the rigid body of the sliding seat, which is not conducive to the lack of miniaturization of the linear sliding rail.

In the Republic of China Patent No. M338929 "Linear Slide for Quick Disassembly Lubrication Device", a scraper blade is combined between an end cover of a rigid body of a carriage and a fixing piece, and the blade is scraped with a screw. And the fixing piece is screwed to the end cover; in the "linear motion device" of Japanese Patent Laid-Open No. 11294451, an oil storage piece and a scraping oil piece are combined between an end cover of a sliding body rigid body and a protective cover. And screwing the oil storage piece, the oil scraping piece and the protective cover to the end cover with a screw. Although these predecessors can solve the shortcomings of the plastic material scraper exposed to the environment and easily collide and damage, the predecessor is that the screw for the fixed use is screwed into the end cap, and the end cap cannot be overcome by the impact of the rolling element. The resulting stress concentration phenomenon, as well as the material of the end cap due to the release of bonding stress over time, leads to the loss of components such as the wiper blade.

The inventor of the present invention has proposed the Republic of China Patent No. I397640 "Strength, Slide and Linear Slides for Sliding Seats", Republic of China Patent No. 201335496 "Structural Construction of Linear Slides", Republic of China Patent No. I285244 In the previous case of "linear slide", in these predecessors, in order to increase the strength of the end cap of the rigid body of the slide, a metal reinforcing piece was placed on the outer side of the end cover.

The invention further uses the reinforcing sheet as a base layer of the screw-solid scraping oil sheet and the protective cover. Therefore, the present invention provides an external sealing sheet structure and a sliding seat assembly, wherein the sliding seat assembly includes the external sealing sheet, and the external sealing sheet is locked on the outer side of the sliding body. On the reinforcing sheet of the end cover, the stress concentration caused by the impact of the rolling element on the end cover is solved, and since the end cover is made of resin, the stress of the screw locked on the resin is released with time, so that the external sealing piece is easy. Loose phenomenon.

The sliding seat assembly comprises: a sliding body rigid body, the sliding body rigid body has an end cover at each end, and the end cover has a reinforcing piece, and the external sealing piece is coupled to the reinforcing piece. The external sealing sheet comprises: a scraping oil piece corresponding to the reinforcing piece; a metal scraping plate corresponding to the scraping piece; a fixing piece passing through the metal scraping plate and the scraping piece and locked in the reinforcing On the sheet, the metal scraper and the oil scraper are fixed on the reinforcing sheet.

Further, the scraping blade has more than one fixing hole for the fixing member to pass through, and a sleeve is placed in the fixing hole. Preferably, the length of the sleeve is comparable to the depth of the fixing hole.

Further, the oil scraping blade has a plurality of positioning posts, and the metal scraping plate has a corresponding plurality of positioning holes.

Further, the oil scraper has a recess in the concave surface facing the reinforcing sheet. Further, an oil reservoir is placed in the groove.

Further, the oil scraper has an inner edge, and the inner edge ring has a groove.

Further, the fixing member is a bolt, and the reinforcing piece has a threaded hole corresponding to the bolt. Preferably, in order to allow the fixing member to be stably locked to the reinforcing sheet, an extension portion is formed at a position of the threaded hole of the reinforcing sheet for extending the length of the threaded hole.

The effect of the invention is:

1. The oil scraper and the metal scraper are locked on the reinforcing sheet, so that the problem that the fixing member is locked on the end cover and the stress is concentrated and the fixing member is easily loosened can be solved; in addition, the rigid body of the sliding seat does not need to reserve space for The fixing member is locked to facilitate the miniaturization of the linear slide rail.

2. The two-layer arrangement of the scraping oil piece and the metal scraper is separated, so that the scraping piece of the plastic deformation material can be closer to the track of the slide rail, and the scraping effect of the scraping oil on the track of the slide rail is improved.

3. The fixing hole on the oil scraping piece is placed in the sleeve, which can avoid excessive compression of the oil scraping piece when the fixing piece is locked, and can maintain the working thickness required for the oil scraping piece.

4. The metal squeegee with better rigidity is located on the outer side of the oil squeegee to avoid damage of the oil squeegee due to collision.

5. The groove of the inner edge of the oil scraper can provide a margin for deformation of the oil scraper.

6. The groove on the oil scraper can accommodate the oil storage block and does not increase the volume of the slide assembly, contributing to the miniaturization of the entire mechanism.
