Description

Technical Field

[0001] This utility model belongs to the field of protective cover technology, and particularly relates to a telescopic steel plate protective cover structure. Background Technology

[0002] Telescopic steel plate protective covers are important devices used in machine tool equipment to protect key moving parts such as guide rails and lead screws from foreign objects such as chips and coolant.

[0003] Traditional telescopic steel plate covers typically have sealing scrapers (brushes or rubber strips) between each section of the cover. Their main function is to prevent small debris from entering the gaps between the overlapping steel plates inside the cover, and also to some extent, to limit the relative detachment of each section of the cover.

[0004] However, there are obvious drawbacks to setting up a sealing scraper structure: First, the scraper itself increases the overall thickness of the protective cover, which reduces its applicability in situations where installation space is limited; second, the scraper is a consumable part, which is prone to wear, aging or deformation after long-term use, which not only loses the sealing effect, but also requires frequent replacement, increasing maintenance costs.

[0005] Simply removing the scraper structure can effectively reduce the thickness of the protective cover, but it will bring new problems: the lack of effective mechanical restraint between the sections of the protective cover will easily cause overstretching and disengagement during the telescopic movement, resulting in the failure of the entire protective cover and its inability to work properly. Utility Model Content

[0006] This utility model addresses the problems existing in the prior art by proposing the following technical solution: A telescopic steel plate protective cover structure includes a protective cover body, a telescopic cover, a sliding mechanism, impact pads, and a limiting component. The protective cover body has a receiving cavity 1 on its front side. The telescopic cover is slidably connected to the receiving cavity 1 via the sliding mechanism. The telescopic cover has a second receiving cavity on its front side, and another telescopic cover is slidably connected to the receiving cavity 2 via the sliding mechanism. Multiple telescopic covers are nested sequentially and are all trapezoidal in shape. The sliding mechanism includes slide rails formed on the inner walls of the receiving cavities 1 and 2, and a slider slidably disposed within the slide rails. The slider is fixedly installed on the outer wall of the telescopic cover. A fixing protrusion is connected to the top of the inner wall of the slide rails. A limiting groove is formed on the outer wall of the slider, and the fixing protrusion is inserted into the limiting groove. Impact pads are equidistantly connected to the bottom ends of the inner walls of both the receiving cavities 1 and 2.

[0007] As a preferred embodiment of the above technical solution, the fixing protrusion has a mushroom-shaped structure, and its top arc-shaped portion is made of elastic materials such as rubber.

[0008] As a preferred embodiment of the above technical solution, there are multiple retractable covers, and the multiple retractable covers are sequentially nested and connected by the sliding mechanism.

[0009] The beneficial effects of this utility model are as follows: Significantly reduced stacking thickness: By completely eliminating the traditional sealing scraper structure, the physical space occupied by the scraper is directly reduced, making the overall cross-section of the cover more compact and suitable for narrower installation spaces.

[0010] Effectively solves the problem of disengagement: By using the unique "mushroom head" shaped fixing protrusion and the upper limit groove of the slider to form a reliable mechanical limiting mechanism.

[0011] This mechanism can achieve a hard limit when the protective cover extends to its maximum stroke, effectively preventing the sections of the protective cover from detaching from each other due to inertia or external force, thus ensuring the stability and reliability of the protective cover's operation.

[0012] Reduced maintenance costs: By eliminating the easily damaged scraper parts, frequent replacement and maintenance work due to scraper wear and aging is avoided, thus reducing the long-term operating costs and downtime of the equipment.

[0013] Buffering and shock absorption, extending service life: The impact pads located at the bottom of the housing provide cushioning when the cover retracts to the bottom, reducing direct impact and wear between metal parts, reducing operating noise, and extending the service life of the cover.

[0014] Compact structure and smooth operation: The trapezoidal telescopic cover, combined with the slide rail slider mechanism, ensures smooth and stable telescopic movement of the cover. The overall structure is reasonably designed, compact and efficient. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] like Figure 1 and Figure 2 As shown in the embodiment of this utility model, the telescopic steel plate protective cover structure mainly consists of a protective cover body 1, a telescopic cover 4, a sliding mechanism, an impact pad 3, and a limiting component composed of a fixed protrusion 7 and a limiting groove 8.

[0019] The protective cover 1 serves as the outermost fixed section, with an opening on its front side forming a receiving cavity 2. A retractable cover 4 is nested and slidably connected to the receiving cavity 2 via a sliding mechanism on it. The retractable cover 4 itself also has a receiving cavity 9 on its front side to accommodate the next retractable cover 4. Similarly, multiple retractable covers 4 can be set as needed. They are connected in sequence by nesting with the same structure to form a multi-section retractable structure. The cross-section of all retractable covers 4 is designed to be trapezoidal, which is conducive to mutual guidance and accommodation during the expansion and contraction process, making the structure more compact.

[0020] The sliding mechanism is the core of realizing the relative movement of each section of the cover. It includes a slide rail 6 that is precisely opened on the inner wall of the first receiving cavity 2 and the subsequent second receiving cavities 9. Correspondingly, a slider 5 is fixedly installed on the outer wall of each retractable cover 4 at a position corresponding to the slide rail 6. The slider 5 is embedded in the slide rail 6 and can slide smoothly along the slide rail 6, thereby guiding and supporting the extension and retraction movement of each section of the cover.

[0021] To prevent the sections of the protective cover from detaching when fully extended, this invention features a unique mechanical limiting mechanism. A fixing protrusion 7 is fixedly connected to the top of the inner wall of the slide rail 6. In this embodiment, the fixing protrusion 7 is preferably mushroom-shaped with a rounded top. This rounded head is made of rubber or other materials with good elasticity and wear resistance. A limiting groove 8 is provided on the outer wall of the slider 5 at a corresponding position. When the protective cover extends to its maximum stroke, the slider 5 slides to the end of the slide rail 6. At this time, the fixing protrusion 7 is precisely engaged in the limiting groove 8 of the slider 5. The mushroom-shaped design allows the elastic head to deform during normal extension and retraction, allowing the slider 5 to pass smoothly. When the end of the stroke is reached, the head returns to its shape and engages in the groove, forming an effective limit and preventing the slider 5 and the entire retractable cover 4 from sliding out further, thereby completely solving the detachment problem.

[0022] In addition, multiple impact pads 3 are installed at equal intervals on the bottom of the inner wall of each of the first and second cavities 9. These impact pads 3 are usually made of cushioning materials such as polyurethane and rubber. When the protective cover retracts, the end of the inner protective cover will impact these impact pads 3 at the bottom of the outer protective cavity, rather than directly impacting the metal cover. This provides good cushioning, shock absorption and noise reduction, protects the protective cover structure and extends its service life.

[0023] Working principle: The protective cover 1 is fixedly installed on the machine tool equipment. When the protected guide rail or lead screw moves, it drives the innermost telescopic cover 4 to move. Through the cooperation of the slider 5 and the slide rail 6, the middle telescopic covers 4 are pulled out section by section to realize the extension of the protective cover. During this process, the slider 5 slides along the slide rail 6. After the elastic head of the fixed protrusion 7 is squeezed and deformed, it passes over the slider 5. When it extends to the maximum design stroke, the limiting groove 8 on the slider 5 moves to the bottom of the fixed protrusion 7. Under the action of elastic restoring force, the head of the fixed protrusion 7 quickly gets stuck in the limiting groove 8, forming a mechanical interlock, preventing the slider 5 from continuing to move forward, thereby preventing the section of the cover from coming off.

[0024] When the shield retracts, the movement process is reversed, and each section of the shield retracts in sequence. Finally, the end of the inner shield will press against the impact pad 3 on the inner bottom of the outer shield. The energy is absorbed by the deformation of the impact pad 3, achieving gentle stopping.

[0025] Throughout the entire movement, no sealing or scraping brushes are required for guidance or limiting; stable and reliable extension and limiting are achieved purely through mechanical structures.

[0026] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
