In view of the above, it is desirable to provide a holder structure on a slider with a simple structure and a good dust-proof effect.
In order to solve the technical problem, the technical scheme of the utility model is that: a retainer structure on a sliding seat comprises an upper retainer which is formed by secondary injection molding with the sliding seat, wherein the upper retainer is provided with a contact part which is always kept in contact with the side wall of the top surface of a sliding rail along the moving direction of the sliding seat, and the contact part is provided with an elastic groove for enhancing the contact elasticity of the contact part.
Furthermore, the part of the contact part close to the slide rail is bent towards the outer side of the slide rail to form an elastic groove.
Furthermore, a two-way dustproof preparation groove is formed between the contact part and the sliding seat.
Furthermore, the notch of the two dustproof preparation grooves faces the top surface of the sliding rail.
Furthermore, the number of the upper retainers in the same sliding seat is two, and the two upper retainers are respectively positioned on two sides of the top surface of the sliding rail.
Furthermore, oil passage through channels are synchronously formed on the sliding seats in the middle of the two upper retainers through secondary injection molding.
Further, the notch of the elastic groove faces the outer side of the sliding rail.
Furthermore, both ends of the contact part are higher than the end face of the sliding seat and respectively form an extension section.
Furthermore, the outer end face of the extension section is higher than the highest point of the rolling element in the rolling element circulation path on the end face of the sliding seat.
Compared with the prior art, the utility model discloses following beneficial effect has: this device is moulded plastics through the secondary on the slide and is constituted and keep the ware to set up the elasticity of elasticity recess in order to strengthen the contact site on keeping the ware last, ensure the slide and remove the in-process, the difficult pine of contact site and slide rail takes off, reaches better dustproof effect.
In order to make the aforementioned and other objects, features and advantages of the present invention comprehensible, preferred embodiments accompanied with figures are described in detail below.

Fig. 2 is a perspective view of an embodiment of the present invention.
Fig. 3 is a schematic plan view of the structure of the embodiment of the present invention.
In the figure: 1-sliding rail, 2-sliding seat, 21-rolling element, 3-upper retainer, 31-extension section, 32-contact part, 33-elastic groove, 34-two dustproof preparation grooves and 35-oil passage through channel.
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 holder-on-carriage structure includes an upper holder 3 that is injection molded two-shot with a carriage 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 upper holder 3 in this embodiment is used to solve the above-mentioned second and third defects. The upper retainer structures are respectively positioned at two sides of the top surface of the sliding rail and play a dustproof role in partial area of a rolling element circulation passage in the sliding seat, and certainly, the upper retainer, other retainer structures, an end cover and an end dustproof sheet of the sliding seat form a dustproof system surrounding the rolling element circulation passage together; the upper retainer structure in this application is a partial structure of the rolling element circulation path dustproof system.
Go up holder 3 and have one along slide moving direction and keep the contact site 32 that keeps contact with the slide rail lateral wall all the time, the part that contact site 32 closes on the slide rail is bent and is constituted an elastic groove 33 to the slide rail outside of partial deviation, through the design of this elastic groove 33, make the part that contact site 32 contacts slide rail 1 have certain elastic 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, contact site 32 can keep the contact with slide rail 1 all the time, thereby play better dustproof effect.
In this embodiment, the notch of the elastic groove 33 faces the outside of the slide rail 1.
A two-way dust-proof preparation groove 34 is provided between the contact portion 32 and the slider 2. The secondary dust-proof preparation tank 34 may accommodate a secondary dust-proof device. Thereby the dust-proof effect of the retainer is better.
In this embodiment, the notch of the two dustproof preparation slots 34 faces the top surface of the slide rail.
Both ends of the contact portion 32 are higher than the end surface of the slide 2 and respectively form an extension 31, and the outer end surface of the extension 31 is higher than the highest point of the rolling element 21 in the rolling element circulation path on the end surface of the slide. 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 presence of the extension 31 allows the gaps at the two ends of the slide 2, in particular the gaps which are susceptible to the ingress of foreign bodies, to be covered, ensuring that foreign bodies cannot enter the rolling element circulation path from these gaps, ensuring a dust-proof effect.
The number of the upper retainers 3 in the same sliding seat 2 is two, and the upper retainers are respectively positioned on two sides of the top surface of the sliding rail. The sliding seats in the middle of the two upper retainers are synchronously injection-molded with oil passage through channels 35 in a secondary injection molding mode. This oil circuit through passage 35 can accomplish unilateral oiling, bilateral lubricated function.
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.
