Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a hinge with a protective cover. Background Technology

[0002] Hinges are a common type of hinge for doors and windows in daily life. They are mainly used for the opening and closing of doors and windows. Ordinary hinges are made of metal and are directly connected to the hinge shaft for rotation. If the hinge is not used for a long time, it may rust. Therefore, a hinge with a protective cover is needed.

[0003] In the existing technology, hinges with protective covers are connected by a tight fit between the protective plates and the plates using snap-fit ​​posts and snap-fit ​​holes. The protective plates will not come off the plate, and no abnormal noise will be produced when opening the door (window). They have the characteristics of simple structure, low cost, convenient installation and disassembly, and strong and reliable connection. However, the protective plates of the hinges are often inconvenient to install, and the practicality of hinges with protective covers is generally limited. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a hinge with a protective cover, which aims to improve the problem that the protective plates of existing hinges with protective covers are often inconvenient to install and the practicality of the protective cover hinges is generally limited.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a hinge with a protective cover, comprising a spindle, a leaf blade rotatably connected to the outer side of the spindle, a bolt uniformly threaded inside the leaf blade on the side away from the spindle, limit grooves formed on both the front and rear sides of the leaf blade, and limit holes uniformly formed at the front and rear of the center of the side away from the spindle, a limit shaft slidably connected inside the limit hole, a protective plate fixedly connected to the upper part of the limit shaft, and mounting grooves formed on both the front and rear sides of the protective plate, with mounting components provided inside the mounting grooves for installing the protective cover.

[0006] As a further description of the above technical solution:

[0007] The mounting assembly includes a fixing block, which is fixedly connected to the left and right sides of the inner side of the mounting groove. A mounting shaft is fixedly connected to the rear side of the fixing block. A telescopic spring is provided on the outer side of the mounting shaft. A sliding block is slidably connected to the rear side of the mounting shaft. A sliding plate is fixedly connected to the front side of the sliding block. A mounting plate is fixedly connected to the front side of the sliding plate. A connecting block is fixedly connected to the lower rear side of the mounting plate. A limit block is fixedly connected to the rear side of the connecting block.

[0008] As a further description of the above technical solution:

[0009] The lower part of the protective plate has grooves evenly distributed on the opposite side, and the upper part of the bolt is slidably connected inside the groove.

[0010] As a further description of the above technical solution:

[0011] The protective plate is made of stainless steel.

[0012] As a further description of the above technical solution:

[0013] One end of the telescopic spring is fixedly connected to the fixed block, and the other end of the telescopic spring is fixedly connected to the sliding block.

[0014] As a further description of the above technical solution:

[0015] A pull ring is fixedly connected to the center of the front side of the mounting plate, and the sliding plate is slidably connected inside the mounting groove.

[0016] As a further description of the above technical solution:

[0017] The limiting block is slidably connected inside the limiting groove.

[0018] This utility model has the following beneficial effects:

[0019] In this invention, pulling the pull ring causes the mounting plate to move, which in turn moves the sliding plate, which in turn moves the sliding block. The sliding block compresses the telescopic spring, and finally, releasing the pull ring causes the sliding block to lose its tension. The telescopic spring then returns to its original position, pushing the sliding block. The sliding block then pulls the mounting plate through the sliding plate, which in turn moves the connecting block. The connecting block then moves the limiting block into the limiting groove, thus facilitating the installation of the hinge's protective plate and improving the practicality of the protective cover hinge.

[0020] In this invention, by pushing the protective plate, the protective plate causes the limiting shaft to slide into the limiting hole, and the upper part of the bolt slides into the groove, so that the protective plate and the leaf fit together. This prevents the upper part of the bolt and the surface of the two protective plates from being exposed, resulting in an aesthetically pleasing appearance. It effectively prevents oxidation and corrosion on the surface of the leaf and the upper part of the bolt, and improves the service life of the hinge. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Reference Figure 1-Figure 3 This utility model provides an embodiment of a hinge with a protective cover, comprising a spindle 2, with a leaf piece 1 rotatably connected to the outer side of the spindle 2. Limiting grooves 9 are formed on both the front and rear sides of the leaf piece 1. Mounting grooves 7 are formed on both the front and rear sides of the protective plate 6. An mounting assembly is provided inside the mounting groove 7 for mounting the protective cover. The mounting assembly includes a fixing block 8, which is fixedly connected to the left and right sides of the inner outer side of the mounting groove 7. A mounting shaft 10 is fixedly connected to the rear side of the fixing block 8. A telescopic spring 11 is provided on the outer side of the mounting shaft 10. A sliding block 12 is slidably connected. A sliding plate 13 is fixedly connected to the front side of the sliding block 12. A mounting plate 14 is fixedly connected to the front side of the sliding plate 13. A connecting block 16 is fixedly connected to the lower rear side of the mounting plate 14. A limit block 17 is fixedly connected to the rear side of the connecting block 16. One end of a telescopic spring 11 is fixedly connected to a fixed block 8. The other end of the telescopic spring 11 is fixedly connected to the sliding block 12. A pull ring 15 is fixedly connected to the middle front side of the mounting plate 14. The sliding plate 13 is slidably connected inside the mounting groove 7. The limit block 17 is slidably connected inside the limit groove 9.

[0028] During the installation of the hinge guard plate 6, the pull ring 15 is first pulled to effectively move the mounting plate 14. As the mounting plate 14 moves, the sliding plate 13 is also moved, which in turn pushes the sliding block 12 forward. The forward movement of the sliding block 12 compresses the telescopic spring 11, increasing its internal pressure. At this time, the operator releases the pull ring 15, causing the sliding block 12 to lose tension. This causes the telescopic spring 11 to quickly return to its original state, releasing the previously stored energy and pushing the sliding block 12 backward. The sliding block 12 is then pulled again by the sliding plate 13. The movable mounting plate 14 is moved backward, which in turn drives the connecting block 16 to slide. The movement of the connecting block 16 eventually causes the limiting block 17 to slide into the limiting groove 9, thereby achieving a secure installation of the hinge protection plate 6. The successful completion of this series of actions not only improves the installation efficiency of the protective cover hinge, but also significantly enhances its practicality. Through this design, the entire installation process becomes simpler and more efficient, ensuring that the protective plate 6 can be firmly fixed on the hinge and provide reliable protection. This optimization of the mechanism is of great significance for improving the overall performance and service life of the equipment.

[0029] Reference Figure 1-Figure 3 Limiting holes 4 are evenly opened at the front and back of the middle of the side away from the blade 1. Limiting shafts 5 are slidably connected inside the limiting holes 4. A protective plate 6 is fixedly connected to the upper part of the limiting shaft 5. The protective plate 6 is made of stainless steel. Bolts 3 are evenly threaded inside the side away from the blade 1. Grooves are evenly opened at the lower part of the protective plate 6 on the side away from the blade. The upper part of the bolts 3 is slidably connected inside the grooves.

[0030] During equipment assembly, the protective plate 6 is first pushed to effectively slide the limiting shaft 5 into the limiting hole 4. As this action is completed, the bolt 3 also slides into the groove. This series of operations ensures a tight fit between the protective plate 6 and the blade 1, forming a complete protective structure. The protective plate 6 is made of stainless steel, which not only enhances its durability but also effectively improves its protective effect. Through this design, the stainless steel protective plate 6 can provide comprehensive protection for the bolt 3 and the blade 1, preventing damage from external factors. This combination of structures not only improves the safety of the equipment but also extends the service life of the components, ensuring the stability and reliability of the equipment during long-term operation. Therefore, the effective application of the protective plate 6 is of great significance for the functional maintenance of the entire equipment.

[0031] Working principle: When the protective cover hinge needs to be installed, pull the pull ring 15 to move the mounting plate 14. The mounting plate 14 moves the sliding plate 13, which in turn moves the sliding block 12. The sliding block 12 compresses the telescopic spring 11, which in turn pushes the protective plate 6, causing the limiting shaft 5 to slide into the limiting hole 4. Finally, release the pull ring 15 to release the tension of the sliding block 12. The telescopic spring 11 loses its pressure and resets, pushing the sliding block 12. The sliding block 12 pulls the mounting plate 14 through the sliding plate 13. The mounting plate 14 moves the connecting block 16, which in turn moves the limiting block 17 into the limiting groove 9. This makes it easier to install the protective plate 6 of the hinge and improves the practicality of the protective cover hinge.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
