Description

Technical Field

[0001] This utility model relates to the field of steel strip skeleton technology, specifically to a composite steel strip skeleton for high load-bearing slide rails. Background Technology

[0002] In many fields such as industrial production, warehousing and logistics, and heavy machinery, slide rails are key structures for enabling the sliding and displacement of components. Their performance directly affects the operating efficiency and safety stability of equipment. With the rapid development of modern industry, various equipment has put forward increasingly higher requirements for the load-bearing capacity of slide rails. In the process of using slide rails, it is usually necessary to equip them with steel strip skeletons.

[0003] On the one hand, the frame structure of traditional slide rails is mostly made of a single metal material. Although it has a certain load-bearing capacity, its bending resistance is often insufficient when facing high loads, and it is prone to plastic deformation due to long-term stress. At the same time, the weight of a single metal material is relatively large, which not only increases the burden on the slide rail itself, but also hinders the lightweight design of the equipment. In addition, some slide rails are excessively thickened in pursuit of load-bearing performance, resulting in a bulky overall structure, which is also susceptible to corrosion during long-term use, further reducing its service life and stability.

[0004] On the other hand, the connections between the frame and the rail body, and between the components within the frame, of traditional slide rails are relatively fixed, making disassembly and assembly complex and cumbersome. When a section of the slide rail is damaged and requires repair or replacement, the entire structure often needs to be disassembled, which not only consumes a lot of time and manpower but may also cause unnecessary damage to other intact components. Moreover, the frame structure design of traditional slide rails lacks an effective stress dispersion mechanism. Under high loads, stress tends to concentrate in localized areas, leading to frame deformation or even damage, affecting the overall service life and safety performance of the slide rail. Against this backdrop, we propose a composite steel strip frame for high-load-bearing slide rails. Utility Model Content

[0005] The purpose of this utility model is to provide a composite steel strip skeleton for high load-bearing slide rails. By setting a steel strip skeleton body (with a U-shaped frame, a three-layer structure, a fiber-reinforced composite material layer, and a stainless steel protective layer) and several reinforcing ribs on the frame, it solves the problems of insufficient load-bearing capacity and easy deformation of traditional slide rails. By using several guide strips, several limit strips, several screws, several bolts and other detachable connection structures, it solves the problem of inconvenient disassembly and assembly of internal components of the slide rail.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A composite steel strip frame for a high-load-bearing slide rail includes a composite steel strip frame and a slide rail body. The composite steel strip frame includes a frame in the shape of a U-shape. The top surface of the slide rail body is provided with a groove, and the inner bottom wall of the slide rail body is provided with a slot communicating with the groove on its top surface. The frame and the slot on the inner bottom wall of the slide rail body are slidably inserted into each other. Several reinforcing ribs are embedded on the left and right sides of the frame. The left and right sides of the frame are fixedly connected to the slide rail body by several bolts. Several steel strip frame bodies are provided between the upper and lower inner walls of the frame. The steel strip frame body includes a high-strength carbon steel strip, a fiber-reinforced composite material layer fixedly sleeved on the outer wall of the high-strength carbon steel strip, and a stainless steel protective layer fixedly sleeved on the outer wall of the fiber-reinforced composite material layer. A guide strip is fixed on the bottom surface of the stainless steel protective layer and slidably connected to the inner bottom wall of the frame. The guide strip and the inner bottom wall of the frame are detachably fixed together.

[0008] In a preferred embodiment, the size of the frame is adapted to the size of the slot on the bottom wall of the slide rail body, and the top surface of the frame and the inner bottom wall of the slide groove on the inner wall of the slide rail body are on the same horizontal plane.

[0009] In a preferred embodiment, several through holes communicating with the inside of the slot are provided on both the front and rear surfaces of the slide rail body, and several threaded holes of the same size and corresponding to the through holes on the outer wall of the slide rail body are provided on both the left and right surfaces of the frame. The bolt rod passes through the through hole on the outer wall of the slide rail body and is threadedly connected to the threaded hole on the outer wall of the frame.

[0010] These two settings ensure a smooth and continuous sliding surface for the slide rail, reducing sliding resistance, improving smooth operation, and making the frame and slide rail body more securely fixed, preventing loosening and displacement under high loads.

[0011] In a preferred embodiment, the left and right sides of the frame are provided with a plurality of reinforcing grooves arranged linearly at equal intervals and in the shape of an X. The plurality of reinforcing grooves on the left and right sides of the frame are arranged from front to back, and a plurality of reinforcing ribs are respectively embedded in the corresponding reinforcing grooves on the outer wall of the frame.

[0012] This feature enhances the frame's resistance to deformation and more effectively disperses the stress transmitted by the steel strip skeleton.

[0013] In a preferred embodiment, the inner bottom wall of the frame is provided with a plurality of guide grooves arranged from front to back, the inner top wall of the frame is provided with a plurality of limiting grooves, the guide strip is slidably connected to the corresponding guide groove on the inner bottom wall of the frame, and a limiting strip is fixed on the top surface of the stainless steel protective layer and slidably connected to the limiting groove on the inner top wall of the frame.

[0014] In a preferred embodiment, the longitudinal cross-sectional shape of the guide groove on the bottom wall of the frame is I-shaped, and the shape of the guide strip is I-shaped to match the shape of the guide groove on the bottom wall of the frame.

[0015] These two features enable more precise installation and positioning of the steel strip skeleton within the frame, and limit its vertical and horizontal displacement, making the connection between the guide strip and the frame tighter and preventing detachment or shaking during sliding.

[0016] In a preferred embodiment, several of the steel strip skeleton bodies are arranged linearly and equally spaced from left to right inside the frame. The longitudinal cross-sectional shape of the high-strength carbon steel strip, the fiber-reinforced composite material layer and the stainless steel protective layer are all semi-circular, and the radius of the semi-circular cross-section of the stainless steel protective layer is the same as the inner height of the frame.

[0017] In a preferred embodiment, the guide strip is fixedly connected to the inner bottom wall of the frame by a number of screws. The bottom surface of the frame is provided with a number of mounting grooves that communicate with the guide grooves on the same side of the inner bottom wall. The bottom surface of the guide strip is provided with a number of mounting holes that correspond to the positions of the mounting grooves on the same side of the bottom surface of the frame. The shank of the screw passes through the mounting groove on the same side of the bottom surface of the frame and is threadedly connected to the mounting hole on the same side of the bottom surface of the guide strip. The screw head is located inside the mounting groove on the same side of the bottom surface of the frame.

[0018] These two features ensure that the steel strip frame is subjected to uniform stress, make full use of the internal space of the frame to increase the overall load-bearing capacity, and ensure that the guide strip is firmly fixed while avoiding the protruding screw head from affecting the overall structure and sliding of the slide rail.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model, by setting up a U-shaped frame and several steel strip skeleton bodies, and the steel strip skeleton bodies are composed of high-strength carbon steel strips, fiber-reinforced composite material layers and stainless steel protective layers, and their shapes are designed as semi-circles, realizes the organic combination of the advantages of each material; the high-strength carbon steel strip provides strong basic load-bearing capacity, laying a solid foundation for bearing heavy objects; the fiber-reinforced composite material layer on the outside of the high-strength carbon steel strip utilizes its high specific strength characteristics to significantly improve the bending resistance of the steel strip without significantly increasing the weight. The two work together to greatly meet the use requirements of higher loads, achieving the effect of significantly improving the overall load-bearing capacity of the slide rail, enabling the slide rail to stably bear heavier items, and is suitable for various scenarios with strict load-bearing requirements.

[0021] 2. This utility model achieves multiple functions by setting several reinforcing ribs on the left and right sides of the frame, as well as several guide strips, limiting strips, screws, and bolts. The reinforcing ribs increase the rigidity of the frame, enabling it to better resist various stresses transmitted from the steel strip skeleton body, effectively preventing deformation of the outer frame under high loads, and thus ensuring the stability of the entire slide rail structure. Simultaneously, the guide strips cooperate with the guide grooves on the bottom wall of the frame, the limiting strips cooperate with the limiting grooves on the top wall of the frame, and the guide strips are fixed to the frame with screws, while the frame is fixed to the slide rail body with bolts. These designs facilitate convenient assembly and disassembly of the several steel strip skeleton bodies, and also facilitate the installation and disassembly of the entire frame. This achieves the effect of ensuring the stability of the slide rail structure while greatly facilitating later maintenance, repair, and adjustments to the internal structure of the slide rail according to actual needs, thus improving the practicality and maintenance efficiency of the slide rail.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-7 This utility model provides a technical solution: a composite steel strip frame for a high-load-bearing slide rail, comprising a composite steel strip frame 2 and a slide rail body 1. The composite steel strip frame 2 includes a frame 21 in the shape of a U-shape. A groove is provided on the top surface of the slide rail body 1, and a slot is provided on the inner bottom wall of the slide rail body 1 that communicates with the groove on its top surface. The frame 21 is slidably inserted into the slot on the inner bottom wall of the slide rail body 1. Several reinforcing ribs 23 are embedded on both the left and right sides of the frame 21. Several bolts 3 are used to connect both sides of the frame 21 to the slide rail body. 1. Fixed connection: Several steel strip skeleton bodies 22 are provided between the upper and lower inner walls of the frame 21. The steel strip skeleton body 22 includes a high-strength carbon steel strip 221, a fiber-reinforced composite material layer 222 fixedly sleeved on the outer wall of the high-strength carbon steel strip 221, and a stainless steel protective layer 223 fixedly sleeved on the outer wall of the fiber-reinforced composite material layer 222. A guide strip 24 is fixedly fixed on the bottom surface of the stainless steel protective layer 223 and slidably connected to the inner bottom wall of the frame 21. The guide strip 24 is detachably fixed to the inner bottom wall of the frame 21.

[0033] In use, the composite steel strip skeleton 2, including the U-shaped frame 21, is slidably inserted into the slot of the slide rail body 1. The frame 21 is fixed with reinforcing ribs 23 and bolts 3. The interior is equipped with a steel strip skeleton body 22 with a three-layer structure and guide strips 24, which improves the load-bearing capacity and stability of the slide rail and facilitates disassembly and maintenance.

[0034] In this embodiment, the size of the frame 21 is adapted to the size of the slot on the inner bottom wall of the slide rail body 1, and the top surface of the frame 21 is on the same horizontal plane as the inner bottom wall of the slide groove on the inner wall of the slide rail body 1. By adapting the size of the frame 21 to the slot of the slide rail body 1, and making its top surface flush with the inner bottom wall of the slide groove, the sliding surface of the slide rail is flat, reducing sliding resistance, ensuring smooth operation, and improving the user experience.

[0035] In addition, several through holes communicating with the inside of the slot are opened on both the front and rear surfaces of the slide rail body 1. Several threaded holes of the same size and corresponding to the through holes on the outer wall of the slide rail body 1 are opened on both the left and right surfaces of the frame 21. The shank of the bolt 3 passes through the through hole on the outer wall of the slide rail body 1 and is threadedly connected to the threaded hole on the outer wall of the frame 21. By aligning the through holes of the slide rail body 1 with the threaded holes of the frame 21 and connecting them with the bolt 3, the frame 21 and the slide rail body 1 are firmly fixed, preventing loosening under high load and enhancing structural reliability.

[0036] Furthermore, several reinforcing grooves arranged linearly and at equal intervals in an X-shape are provided on both the left and right sides of the frame 21. These reinforcing grooves are arranged from front to back, and several reinforcing ribs 23 are embedded in the corresponding reinforcing grooves on the outer wall of the frame 21. By embedding reinforcing ribs 23 in the X-shaped reinforcing grooves on both sides of the frame 21 in a linear and equidistant arrangement, the rigidity of the frame 21 is enhanced, stress is effectively dispersed, deformation under high load is prevented, and structural stability is ensured.

[0037] Specifically, the inner bottom wall of frame 21 is provided with several guide grooves arranged from front to back, and the inner top wall of frame 21 is provided with several limiting grooves. Guide strips 24 are slidably connected to the corresponding guide grooves on the inner bottom wall of frame 21, and limiting strips 25 are fixed on the top surface of stainless steel protective layer 223 and are slidably connected to the limiting grooves on the inner top wall of frame 21. Through the inner bottom guide grooves and inner top limiting grooves of frame 21, which are slidably connected to guide strips 24 and limiting strips 25 respectively, the steel strip skeleton body 22 is accurately positioned during installation, displacement is limited, and structural stability is improved.

[0038] It is worth noting that the longitudinal cross-sectional shape of the guide groove on the inner bottom wall of the frame 21 is I-shaped, and the shape of the guide strip 24 is I-shaped to match the shape of the guide groove on the inner bottom wall of the frame 21. The I-shaped guide groove on the inner bottom of the frame 21 and the matching I-shaped guide strip 24 make the two tightly connected, preventing them from separating or shaking during sliding, and ensuring the stable installation of the steel strip frame body 22.

[0039] It is worth noting that several steel strip skeleton bodies 22 are arranged linearly and equally spaced from left to right inside the frame 21. The longitudinal cross-sectional shape of the high-strength carbon steel strip 221, the fiber-reinforced composite material layer 222, and the stainless steel protective layer 223 are all semi-circular, and the outer radius of the semi-circular cross-section of the stainless steel protective layer 223 is the same as the inner height of the frame 21. By arranging several steel strip skeleton bodies 22 equally spaced within the frame 21, the three-layer structure forms a semi-circle, and the radius of the stainless steel protective layer 223 is adapted to the inner height of the frame 21, resulting in uniform stress distribution, full utilization of space, and improved load-bearing capacity.

[0040] It is worth emphasizing that the guide strip 24 is fixedly connected to the inner bottom wall of the frame 21 by several screws 26. The bottom surface of the frame 21 has several mounting grooves that communicate with the guide grooves on the same side of its inner bottom wall. The bottom surface of the guide strip 24 has several mounting holes corresponding to the mounting grooves on the same side of the bottom surface of the frame 21. The shank of the screw 26 passes through the mounting groove on the bottom surface of the frame 21 and is threadedly connected to the mounting hole on the same side of the guide strip 24. The screw head of the screw 26 is located inside the mounting groove on the bottom surface of the frame 21. By connecting the screw 26 through the mounting groove on the bottom surface of the frame 21 and the mounting hole of the guide strip 24, with the screw head concealed within the groove, the guide strip 24 is firmly fixed without affecting the slide rail structure and sliding, thus balancing stability and practicality.

[0041] In this embodiment, during actual use, the slide groove of the slide rail body 1 undertakes the sliding function, the composite steel strip frame 2 is the load-bearing core, and the left and right sides of the U-shaped frame 21 are fixed to the slide rail body 1 by several bolts 3, and the reinforcing ribs 23 on both sides enhance rigidity and resist stress deformation.

[0042] The high-strength carbon steel strip 221 of the steel strip skeleton body 22 provides the basic load-bearing capacity, the fiber-reinforced composite material layer 222 improves the bending resistance, and the stainless steel protective layer 223 provides protection. Multiple steel strip skeleton bodies 22 are equidistantly distributed, and the semi-circular structure ensures uniform stress distribution and improves the overall load-bearing capacity.

[0043] The guide bar 24 engages with the guide groove on the frame 21, and the limiting bar 25 engages with the limiting groove to restrict the displacement of the steel strip skeleton body 22. The I-beam design enhances connection stability. Screws 26 secure the guide bar 24, ensuring the steel strip skeleton body 22 remains stable under load. The coordinated structure achieves high load-bearing capacity and stable sliding.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
