Abstract
Description
Technical Field
[0001] This utility model relates to the field of hardware accessories, and in particular to a mounting screw pre-fixing component and a hinge. Background Technology
[0002] Currently, hinge assembly typically uses screw fastening. Since the screws are separate from the product, the operator not only needs to repeatedly pick up and drop the screws during installation, making the operation complex and inefficient, but also requires one hand to hold the hinge in place while the other hand is used to pick up and tighten the screws. This can easily lead to hinge misalignment, affecting assembly accuracy. As a result, the assembly process is time-consuming and laborious, resulting in a poor user experience.
[0003] Based on the above, the existing hinge structure and its installation method need further improvement. Utility Model Content
[0004] The first objective of this invention is to overcome the shortcomings of the prior art and provide a pre-fixed mounting screw assembly.

When the screws are fully tightened, the connecting block breaks, ensuring that the screws can be tightened to the end and that the pre-installed seat bursts open and falls off after the screws are installed, thereby reducing the number of parts after the hinge is installed.
[0009] The pre-installed base can be assembled onto the base without complex structures or additional accessories through the cooperation of the snap-fit and notch. The pre-installed base can be fixed by the elasticity of the plastic parts. The structure is simple.

Therefore, it should not be construed as a limitation of this utility model.
[0028] Example 1:
[0029] See Figures 1 to 5 .
[0030] This embodiment discloses a pre-fixing assembly 1 for mounting screws, including a base 2 and at least one pre-fixing structure 3. The base 2 is provided with mounting holes 23, and the pre-fixing structure 3 includes a pre-mounting seat 4. The pre-mounting seat 4 is provided with a pre-mounting hole 41, which is used to pre-fix screws 5. The pre-fixing structure 3 is disposed on the base 2, and the pre-mounting hole 41 corresponds to the mounting hole 23.
[0031] The pre-installation base 4 further includes a fixing part 44 and a positioning part 45. The pre-installation hole 41 is provided on the fixing part 44, and the fixing part 44 is provided with a buckle 441. The base 2 has a notch 21 on its edge, and the buckle 441 is engaged with the notch 21. The base 2 is provided with a plurality of limiting protrusions 22, and the positioning part 45 is disposed between the limiting protrusions 22. In this solution, the limiting protrusions 22 limit the positioning part 45 to fix the installation position of the pre-installation base 4 and prevent the position of the pre-installation base 4 from shifting.
[0032] The pre-installation hole 41 is formed by opposing arc-shaped sidewalls 42, which are connected by a connecting block 43. In this design, the connecting block 43 can withstand a certain stress. During the tightening of the screw 5, the pre-installation hole 41 is gradually opened, and the stress on the connecting block 43 gradually increases. When the screw 5 is fully tightened, the force exerted by the screw 5 on the connecting block 43 reaches the highest stress point, causing the connecting block 43 to break. The pre-installation seat 4 bursts open into two parts, ensuring that the screw 5 can be fully installed while allowing the pre-installation seat 4 to easily detach after installation.
[0033] Specifically, the pre-installation base 4 is made of plastic. In this design, the pre-installation base 4 allows the buckle 441 to be fixed to the base 2 using its own elasticity, making installation convenient, and the pre-installation base 4 is easy to detach after being opened.
[0034] To achieve the alignment and installation of the pre-installation seat 4 and the base 2, the inner wall of the mounting hole 23 is set as an inclined concave surface, and a boss 46 is provided on the lower side of the pre-installation hole 41. The boss 46 matches the mounting hole 23, and the screw 5 passes through the pre-installation hole 41, the boss 46 and the mounting hole 23 in sequence.
[0035] It also includes a housing 6 and a positioning pin 7. The housing 6 is mounted on the base 2, and both sides of the housing 6 are bent downward to form connecting portions 61. The base 2 is provided with a positioning plate 24, which protrudes upward to form a positioning groove 25. The positioning pin 7 passes through the positioning groove 25 and through both sides of the housing 6. In this design, the positioning pin 7 is used to connect the housing 6 and the base plate 2, and the positioning groove 25 fixes the direction and position of the positioning pin 7.
[0036] The outer casing 6 is provided with a relief opening 62, and the screw 5 passes through the relief opening 62.
[0037] The base 2 is provided with an eccentric nail 26, and the outer shell 6 is provided with an adjustment groove 63, which corresponds to the eccentric nail 26. The eccentric nail 26 in this design is used to adjust the installation height of the pre-fixed component 1 on the door panel, making the installation position more precise.
[0038] The outer casing 6 is provided with a plurality of slots 64, which are used for positioning and connection with the hinge 8.
[0039] This invention uses a pre-installation bracket 4 to pre-fix the mounting screws 5 onto the base 2, reducing the steps of removing the screws and ensuring that the screws 5 are perpendicular to the base 2. This allows the screws 5 to be tightened while maintaining a direction perpendicular to the mounting plane, making the operation simple and the installation accurate. Compared with the prior art, the mounting screw pre-fixing component 1 of this invention has higher installation efficiency and installation accuracy.
[0040] Example 2:
[0041] See Figures 6 to 8 .
[0042] This embodiment discloses a hinge 8, including a hinge cup 81, a hinge arm 82, a mounting base 84, and a pre-fixing assembly 1 as described in Embodiment 1. The hinge arm 82 is connected to the hinge cup 81 via a connecting rod structure 83. The mounting base 84 is disposed on the pre-fixing assembly and within the hinge arm 82. Compared with the prior art, the hinge 8 of this utility model has higher installation efficiency and accuracy due to the application of the above-described solution.
[0043] To achieve accurate alignment between the mounting base 84 and the pre-fixed component 1, the mounting base 84 is provided with a first snap-fit part 841 and a second snap-fit part 842. The first snap-fit part 841 is designed as a hook and snaps onto the edge of the connecting part 61, and the second snap-fit part 842 is snapped into the slot 64.
[0044] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
