Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.
As shown in fig. 1 to 3, a slider lower holder structure includes a lower holder 3 that is injection molded two-shot with a slider 2.
By analyzing the service condition of the existing rolling element circulation passage dustproof system, the following three ways of entering foreign matters into the sliding seat 2 can be known, firstly, the foreign matters enter from the two ends of the sliding seat 2, and the defect is well solved by the design of the end dustproof sheet in the prior art; secondly, foreign matters enter from the side wall of the sliding seat 2, and the dust prevention system in the prior art mainly focuses on dust prevention at the end part of the sliding seat 2, so that a good solution is not provided for the dust prevention system; thirdly, foreign matters enter the rolling element circulation path along the connecting gap between the sliding seat end cover and the sliding seat 2.
The lower holder 3 in this embodiment is used to solve the above-mentioned second and third defects. The lower retainer structures are two and are respectively positioned on two opposite side walls of the slide rail, and play a role in preventing dust in partial areas of the rolling element circulation passage in the slide seat, and certainly, the lower retainer, other retainer structures, and the end cover and the end dust-proof sheet of the slide seat form a dust-proof system surrounding the rolling element circulation passage together; the lower retainer structure in this application is a partial structure of the rolling element circulation path dustproof system.
Both ends of the lower retainer 3 are higher than the end surface of the sliding seat 2 and respectively form an extension section 31, and the extension section 31 has the same structure as the lower retainer 3; the outer end surface of the extension 31 is higher than the highest point of the rolling elements 21 in the circulation path of the rolling elements on the end surface of the carriage. The presence of the extension 31 allows the gap between the carriage 2 and its end cap, which is located in the area where the carriage contacts the linear slide 1, to be covered, which gap, without extension, is that of the straight linear slide 1 during sliding, so that foreign bodies can easily enter the rolling element circulation path along this gap; the existence of the extension section 31 enables gaps on both ends of the sliding seat 2, especially gaps which are easy to enter foreign matters, to be covered, ensures that the foreign matters cannot enter a rolling element circulation passage from the gaps, and achieves a seamless dustproof effect.
The lower retainer 3 is provided with a first contact part 32 and a second contact part 34 which are along the moving direction of the sliding seat and are always kept in contact with the side wall of the sliding rail, the part of the first contact part 32 close to the sliding rail is deflected to the outer side of the sliding rail to form a first elastic groove 33, and the second contact part is provided with a second elastic groove 35; through the design of first elastic groove 33 and second elastic groove 35, make the part that first contact site 32 and second contact site 34 contacted slide rail 1 have certain elasticity space, make its contact with slide rail 1 inseparabler, reduce the hardness of this department, make the slide along the slide rail removal in-process, first contact site 32 and second contact site 34 can keep the contact with slide rail 1 all the time, thereby play better dustproof effect.
In this embodiment, the notch of the first elastic groove 33 faces the outside of the slide rail.
A second dust-proof preparation groove 36 for accommodating a second dust-proof device is formed between the first contact portion 32 and the second contact portion 34. The secondary dust-control preparation tank 36 may accommodate a secondary dust-control device. Thereby the dust-proof effect of the retainer is better.
In this embodiment, the notches of the two dustproof preparation grooves 36 face the side walls of the slide rail.
In this embodiment, the first contact portion 32 has a first concave slot 37 on the sidewall of the inner sidewall of the two dustproof preparation slots, and the second contact portion 34 has a second concave slot 38 on the sidewall of the inner sidewall of the two dustproof preparation slots. Through the cooperation of draw-in groove and two dustproof preparation grooves 36 for the second dust keeper can imbed in two dustproof preparation grooves 36, and the second dust keeper can not break away from two dustproof preparation grooves 36 easily.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention has been disclosed by the preferred embodiment, it is not limited to the present invention, and any person skilled in the art can make modifications or changes equivalent to the equivalent embodiments by utilizing the above disclosed technical contents without departing from the technical scope of the present invention, but all the modifications, changes and changes of the technical spirit of the present invention made to the above embodiments are also within the scope of the technical solution of the present invention.
