Abstract
Description
Technical Field
[0001] This utility model relates to the field of slider technology, and in particular to a high-reliability nylon slider. Background Technology
[0002] Linear motion pairs consisting of sliders and guide rails are widely used in off-road RVs, and their performance directly affects the smoothness, accuracy, and lifespan of the equipment. Traditional ordinary sliders require grease lubrication, resulting in high maintenance costs and a high susceptibility to corrosion, causing jamming. To reduce frictional resistance and simplify maintenance, existing technologies often use engineering plastics such as nylon to make sliders, utilizing their self-lubricating properties to reduce reliance on additional lubrication systems.
[0003] However, while nylon possesses excellent friction-reducing and corrosion-resistant properties, its mechanical strength, stiffness, and creep resistance are far lower than those of metallic materials, especially when subjected to threaded connection loads. Currently, common nylon slider structures often employ direct tapping on the slider body, connecting it to an external bracket or protective housing via bolts. While this design appears simple during initial assembly, over long-term use, due to nylon's low hardness and low elastic modulus, it is highly susceptible to thread wear, stripping, and even stripping under repeated vibration, impact, or thermal cycling, leading to loose connections and, in severe cases, slider detachment or malfunction. Furthermore, existing slider-rail connections are mostly semi-open or open structures, failing to effectively prevent dust, sand, moisture, and other contaminants from entering the sliding interface. This not only accelerates wear on the sliding pair but can also cause malfunctions such as jamming and creeping, especially pronounced in harsh conditions such as deserts and coastal areas. Although some solutions have attempted to improve protective performance by adding seals or housings, they often overlook the matching problem between the connection structure and material properties, failing to fundamentally resolve the contradiction between high-strength connection and long-term reliability of nylon sliders.
[0004] Therefore, there is an urgent need for a highly reliable slider structure that can fully utilize the self-lubricating advantages of nylon materials, ensure reliable connection, good sealing, and stable structure, in order to overcome the defects of existing technologies such as easy connection failure, insufficient protection, and frequent maintenance. Utility Model Content
[0005] To overcome the shortcomings of the prior art, this utility model discloses a highly reliable nylon slider.
[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:
[0007] A high-reliability nylon slider, comprising:
[0008] The protective sleeve has a groove-shaped structure.
[0009] The slider is one or more located inside the protective sleeve; the slider is made of nylon and slides with the slide rail through its self-lubricating properties.
[0010] The connecting components consist of multiple components mounted on the slider; the protective sleeve has mounting holes corresponding to the positions of the connecting components.
[0011] The connecting bolts are installed at the mounting holes of the protective sleeve. The connecting bolts cooperate with the connecting components to securely connect the slider to the protective sleeve.
[0012] Preferably, the connection component includes:
[0013] The mounting slot is located on the side of the slider;
[0014] The mounting hole is located on the top of the slider and extends through the mounting groove;
[0015] The nut is placed in the mounting groove; the connecting bolt is inserted into the mounting hole and threadedly connected to the nut.
[0016] Preferably, the protective sleeve is equipped with end caps at both ends, and the end caps are located in openings that are consistent with the cross-sectional shape of the slide rail.
[0017] Preferably, the protective sleeve has threaded holes on both ends, and the end caps are fastened to the protective sleeve by screws.
[0018] Preferably, the inner side of the end cap is provided with a stop protrusion that can be inserted into the corresponding port of the protective sleeve.
[0019] Preferably, the top of the inner side of the protective sleeve is provided with a reinforcing rib along the length of the protective sleeve, and the slider is provided with a groove corresponding to and adapted to the reinforcing rib at the position of the reinforcing rib.
[0020] By adopting the technical solution described above, this utility model has the following beneficial effects:
[0021] (1) The present invention has a simple structure. By setting the slider inside the groove-shaped protective sleeve and using nylon material to make the slider, its self-lubricating properties are fully utilized, so that no additional lubricant is needed when the slider and the slide rail are in contact. This effectively reduces the coefficient of friction and wear. At the same time, a fully enclosed structure is formed between the slider and the slide rail, which significantly improves the dustproof, windproof and moistureproof capabilities, and avoids jamming or functional failure caused by foreign objects entering the device. This enhances the reliability and service life of the device under harsh working conditions.
[0022] (2) This utility model has an independent connecting component on the slider. The connecting bolt passes through the protective sleeve and cooperates with the component to achieve a tight connection, avoiding problems such as stripping and disengagement that are easily caused by the direct threaded connection of the bolt to the nylon slider body. The connecting component includes a mounting groove on the side of the slider, a top mounting hole extending through the groove, and a metal nut embedded in the mounting groove. The connecting bolt is threadedly connected to the metal nut through the mounting hole, so that the load transmission path is transferred from the nylon body to the metal nut. This not only retains the friction reduction and buffering properties of the nylon material, but also ensures the high strength and long-term stability of the connection part, improving the reliability and maintainability of the overall structure.
[0023] (3) The present invention further adds end caps at both ends of the protective sleeve, which smoothly transition with the slide rail after assembly to avoid motion interference; at the same time, the end opening of the protective sleeve is closed to further improve the sealing performance. The end caps are connected to the threaded holes on the end face of the protective sleeve by screws, which is simple in structure and easy to disassemble and maintain; the stop protrusion set on the inner side of the end cap is inserted into the port of the protective sleeve, which not only achieves precise positioning and prevents the end cap from shifting, but also increases the overall rigidity by increasing the contact area, effectively maintaining structural stability and geometric accuracy when bearing lateral loads.
[0024] (4) The present invention further provides reinforcing ribs along the length direction at the top of the protective sleeve, and provides matching grooves at the corresponding positions of the slider. After the two are fitted together, the slider is limited in the width direction to prevent movement. This structure not only improves the positioning accuracy of the slider in the protective sleeve, but also enhances the bending stiffness of the top of the protective sleeve through the reinforcing ribs, thereby ensuring uniform contact between the slider and the slide rail, improving the smoothness of operation and the reliability of long-term use.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0036] Example 1:
[0037] Combined with appendix Figures 1-5 A high-reliability nylon slider includes a protective sleeve 1, a slider 2, and a connecting assembly. As shown in the attached diagram... Figure 5 As shown, the protective sleeve 1 has a groove-shaped structure for accommodating and limiting internal components. One or more sliders 2 are snapped into the protective sleeve 1; the number of sliders can be configured according to load requirements in practical applications. (See attached diagram.) Figure 2As shown, two sliders 2 are snapped into the protective sleeve 1. The sliders 2 are made of nylon, and utilizing the inherent self-lubricating properties of nylon, no additional lubricant is needed during their sliding contact with the slide rail. This effectively reduces the coefficient of friction, minimizes wear, and maintains stable sliding performance over long-term operation. Simultaneously, the engagement between the sliders 2 and the slide rail forms a fully enclosed structure. This structure effectively prevents external dust, sand, and moisture from entering the sliding interface, avoiding jamming, accelerated wear, or functional failure caused by foreign object intrusion. This improves the reliability and service life of the overall device in harsh environments.
[0038] The slider 2 is equipped with multiple connecting components to enhance connection stability; the protective sleeve 1 has mounting holes corresponding to the positions of the connecting components. Connecting bolts 3 are installed at the mounting holes of the protective sleeve 1. The connecting bolts 3 pass through the mounting holes of the protective sleeve 1 and engage with the connecting components, thereby securely connecting the slider 2 and the protective sleeve 1 as a single unit. This connection method avoids direct threaded connection between the connecting bolts 3 and the slider 2 body. Since the slider 2 is made of nylon, its mechanical strength is lower than that of metal, and direct tapping could easily lead to problems such as stripping and disengagement. By using independently designed connecting components to perform the threaded connection function, the structural strength and durability of the connection part can be significantly improved, preventing the connecting bolts 3 from loosening or falling off under long-term vibration or repeated loads, ensuring the stability and safety of the slider assembly during use.
[0039] Specifically, as shown in the attached document Figure 3 and 4 As shown, the connecting assembly includes a mounting groove 4, a mounting hole 5, and a nut 6. The mounting groove 4 is a recessed structure located on the side of the slider 2. The mounting hole 5 is located on the top of the slider 2, extending vertically through the mounting groove 4 on the side of the slider 2 body. The nut 6, typically made of metal, is fitted into the mounting groove 4, possessing good thread strength and shear resistance. The connecting bolt 3, after passing through the mounting hole on the outside of the protective sleeve 1, continues through the mounting hole 5 on the top of the slider 2, ultimately forming a threaded connection with the nut 6 within the mounting groove 4. This structure transfers the force path from the nylon body to the metal nut 6, preserving the self-lubricating and shock-absorbing advantages of the nylon slider 2 while solving the problem of nylon material being unable to directly withstand high-strength threaded connections. This achieves a reasonable division of function and structure, improving the overall reliability and maintainability of the connection.
[0040] Example 2:
[0041] Combined with appendix Figures 1-2Examples 5-7 describe a high-reliability nylon slider, a further improvement upon Example 1. The difference lies in that end caps 7 are installed at both ends of the protective sleeve 1, covering the openings at both ends of the sleeve 1. The end caps 7 have openings with a cross-sectional shape consistent with the slide rail, ensuring a smooth transition between the end caps 7 and the slide rail after assembly, preventing interference or scratches during movement. This design not only improves aesthetic consistency but, more importantly, enhances the sealing performance of the entire slider assembly by sealing the openings at both ends of the protective sleeve 1.
[0042] Specifically, the protective sleeve 1 has threaded holes on both end faces, and the end cap 7 is fastened to the protective sleeve 1 by screws 8. The screws 8 pass through the through holes on the end cap 7 and are screwed into the threaded holes on the end face of the protective sleeve 1, thus reliably fixing the end cap 7. This connection method is simple in structure, easy to assemble and disassemble, and facilitates later maintenance or replacement of the internal slider 2. At the same time, because the end cap 7 and the protective sleeve 1 are rigidly connected, it effectively prevents the end cap 7 from loosening due to vibration during equipment operation, ensuring the durability of the sealing effect.
[0043] Furthermore, the inner side of the end cap 7 is provided with a stop protrusion 9 that can be inserted into the corresponding port of the protective sleeve 1. The stop protrusion 9 forms a transition fit with the inner cavity of the end of the protective sleeve 1. After the end cap 7 is installed in place, the stop protrusion 9 is embedded inside the protective sleeve 1, which plays a positioning and limiting role, preventing the end cap 7 from shifting in the axial or radial direction. In addition, the presence of the stop protrusion 9 increases the contact area and structural rigidity between the end cap 7 and the protective sleeve 1, which can effectively share part of the external load, improve the overall deformation resistance and structural strength of the protective sleeve 1, and especially help maintain the geometric accuracy and operational stability of the slider assembly under lateral impact or off-center load conditions.
[0044] Example 3:
[0045] Combined with appendix Figure 2 , 3 5. A high-reliability nylon slider, further optimized based on Embodiment 1 or Embodiment 2, with the following improvement: A reinforcing rib 10 is provided at the top of the inner part of the protective sleeve 1 along its length. This reinforcing rib 10 is an axially extending protruding structure used to enhance the rigidity and bending resistance of the top area of the protective sleeve 1. The slider 2 has a corresponding groove 11 that matches the reinforcing rib 10. The shape, width, and depth of the groove 11 match the reinforcing rib 10, ensuring that the reinforcing rib 10 is precisely embedded in the groove 11 after the slider 2 is inserted into the protective sleeve 1. This mating structure not only achieves precise positioning of the slider 2 within the protective sleeve 1 but also prevents it from shifting in the width direction.
[0046] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
