Description

Technical Field

[0001] This utility model relates to the field of guide rail technology, specifically a sealed and dustproof linear guide rail pair. Background Technology

[0002] Linear guide pairs are high-precision linear motion guiding devices widely used in mechanical systems. They are mainly used to support and guide moving parts to perform linear reciprocating motion along a fixed track.

[0003] The applicant discovered through a search that a Chinese patent, "A Sealed Dustproof Structure for Linear Guide Rail Pairs," with publication number "CN217519068U," discloses a method for removing dust from the surface of the rail using a dust removal brush. However, due to the light weight of dust, the dust removed by the brush remains near the rail. When people walk or the slider moves on the rail, dust adsorption still occurs, affecting the overall guide rail. Traditional guide rail pairs cannot quickly and conveniently remove and collect dust for unified processing. Therefore, we propose a sealed dustproof linear guide rail pair. Utility Model Content

[0004] The purpose of this utility model is to provide a sealed and dustproof linear guide pair.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealed and dustproof linear guide rail assembly, comprising a guide rail body, a slider slidably connected to the outer side of the guide rail body, scrapers fixedly installed at both ends of the slider, and cleaning covers fixedly installed at both ends of the slider. A first cleaning brush and two second cleaning brushes are rotatably connected to the inner wall of the cleaning cover. A first bevel gear is fixedly installed at both ends of the first cleaning brush and the top of the second cleaning brush. A dust collection frame is fixedly installed on the inner wall of the cleaning cover. Two dust collection trays are connected to one side of the dust collection frame. The outer sides of the two dust collection trays are movably connected to the inner wall of the cleaning cover. A flow guide grille is fixedly installed on the inner wall of the cleaning cover.

[0006] As a further embodiment of this utility model: a guide rod is rotatably connected to the inner wall of the top of the guide grille, and an active rod is rotatably connected to the inner wall of the top of the slider, with both ends of the active rod rotatably connected to the inner wall of the top of the cleaning cover.

[0007] As a further embodiment of this utility model: a drive rod is rotatably connected to the inner wall of the top of the cleaning cover, and a second bevel gear is fixedly installed on the outer side of the drive rod, one end of the active rod, and the top of the guide rod.

[0008] As a further embodiment of this utility model: pulleys are fixedly installed at the other end of the drive rod and the other end of the first cleaning brush, and a transmission belt is sleeved on the outer side of the pulleys.

[0009] As a further embodiment of this utility model: a motor is fixedly installed on the outer side of one of the cleaning covers, and the output end of the motor is fixedly connected to one end of the drive rod.

[0010] As a further embodiment of this utility model: a filter screen is fixedly installed on one inner wall of the dust collection drawer.

[0011] As a further embodiment of this utility model: a connecting handle is fixedly installed on the top of the dust collection drawer.

[0012] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0013] 1. This utility model uses a scraper to clean the dust on the surface of the guide rail body when the slider slides. At the same time, the dust collection frame and dust collection tray inside the cleaning cover can collect and adsorb the dust generated when the scraper moves, thus preventing the dust from spreading to other places and affecting the surrounding environment. The dust collection tray can be removed from inside the cleaning cover, making it easier to uniformly handle the dust, thereby improving the overall performance of the linear guide rail pair.

[0014] 2. This utility model uses the first and second cleaning brushes to scrape the surface of the scraper, which can remove dust from the scraper surface and reduce the residue caused by excessive dust when scraping. This can effectively improve the cleaning and collection effect of dust on the guide rail body and reduce dust residue on the outside.

[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

Detailed Implementation

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0023] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Please see the appendix Figure 1 -Appendix Figure 5 This utility model relates to a sealed and dustproof linear guide pair.

[0025] Example 1 includes a guide rail body 1, a slider 2 slidably connected to the outer side of the guide rail body 1, scrapers 3 fixedly installed at both ends of the slider 2, and cleaning covers 4 fixedly installed at both ends of the slider 2. A first cleaning brush 5 and two second cleaning brushes 51 are rotatably connected to the inner side wall of the cleaning cover 4. A first bevel gear 52 is fixedly installed at both ends of the first cleaning brush 5 and the top of the second cleaning brush 51. A dust collection frame 6 is fixedly installed on the inner side wall of the cleaning cover 4. Two dust collection trays 7 are connected to one side of the dust collection frame 6. The outer sides of the two dust collection trays 7 are movably connected to the inner side wall of the cleaning cover 4. A flow guide grille 8 is fixedly installed on the inner side wall of the cleaning cover 4. A flow guide rod 81 is rotatably connected to the inner wall of the top of the flow guide grille 8. A filter screen 71 is fixedly installed on the inner wall of one side of the dust collection tray 7.

[0026] Specifically, when using this linear guide pair, the slider 2 slides on the guide body 1, thereby driving the scrapers 3 on both sides of the slider 2 to remove residual dust from the surface of the guide body 1. This prevents dust from entering the slider 2 as it moves on the guide body 1. Simultaneously, the rotation of the first cleaning brush 5 drives the second bevel gear 11 to rotate via the action of the first bevel gear 52, causing the two second cleaning brushes 51 to rotate on the surface of the scrapers 3, thus removing dust from the upper surface of the scrapers 3. At this time, the internal flow guide grille 8 guides the flow... When rod 81 rotates, it can guide the airflow inside the guide grille 8, causing the first cleaning brush 5 and the second cleaning brush 51 to rotate and suck the dust on them into the dust collection frame 6 through the opening. Through the connection between the dust collection frame 6 and the dust collection tray 7, the dust continues to flow into the dust collection tray 7. Thus, the air is filtered by the filter screen 71, and the dust is collected inside the dust collection tray 7. The collection tray can be removed from inside the cleaning cover 4, which makes it easier to uniformly handle the dust and improves the dust prevention effect of the overall linear guide pair during use.

[0027] In embodiment 2, an active rod 9 is rotatably connected to the inner wall of the top of the slider 2. The two ends of the active rod 9 are rotatably connected to the inner wall of the top of the cleaning cover 4. A drive rod 10 is rotatably connected to the inner wall of the top of the cleaning cover 4. A second bevel gear 11 is fixedly installed on the outer side of the drive rod 10, one end of the active rod 9, and the top of the guide rod 81. A pulley 12 is fixedly installed on the other end of the drive rod 10 and the other end of the first cleaning brush 5. A transmission belt 13 is sleeved on the outer side of the pulley 12. A motor 14 is fixedly installed on the outer side of one of the cleaning covers 4. The output end of the motor 14 is fixedly connected to one end of the active rod 9. A connecting handle 72 is fixedly installed on the top of the dust collection drawer 7.

[0028] Specifically, when it is necessary to clean and absorb dust and drive the guide rod 81, the motor 14 drives the active rod 9, and the second bevel gear 11 on it drives the guide rod 81 and the drive rod 10, so that the guide rod 81 can rotate inside the guide grille 8, guiding the airflow inside the cleaning cover 4 to the outside. When the drive rod 10 rotates, it can drive the first cleaning brush 5 to rotate through the linkage of the pulley 12 and the transmission belt 13. Then, through the action of the second bevel gear 11, it can drive the second cleaning brush 51 to rotate, which can more effectively remove the dust scraped on the scraper 3.

[0029] Working principle:

[0030] First, slider 2 slides on guide rail body 1, driving scraper 3 to clean the dust adhering to the surface of guide rail body 1. At the same time, the rotation of first cleaning brush 5 and second cleaning brush 51 brushes away the dust remaining on scraper 3. Then, through the rotation of guide rod 81 inside guide grille 8, the dust generated by the first cleaning brush 5, second cleaning brush 51 and scraper 3 can be adsorbed by dust collection frame 6 and connected to dust collection drawer 7. After being filtered by filter screen 71, the dust is collected inside dust collection drawer 7, so that dust collection drawer 7 can be pulled out from inside cleaning cover 4 for unified treatment of dust. At this point, the entire workflow is completed.
