Description

Technical Field

[0001] The utility model relates to a hardware hinge, in particular to a hinge mounting screw pre-installed structure. Background Art

[0002] Screws are widely used as primary fasteners during product assembly and packaging. Most products on the market require screws for fastening together during packaging and assembly. To facilitate installation, manufacturers typically ship several mounting screws with their products, often mixed together in a small bag. However, existing techniques for mounting screws have significant drawbacks, resulting in significant inconvenience for users during installation.

[0003] Currently, the mounting screws for hardware hinges are supplied in bulk. When users need to use them, they must first unpack the packaging, remove the screws, and place them on the floor or workbench. Each time they install a screw, they must bend down to pick it up from the floor or other hard-to-reach areas, then return to their workstation to assemble it. This practice significantly impacts installation efficiency. Users often need one hand to secure the product while the other constantly bends down to retrieve the screws, which is not only time-consuming but also increases the complexity of the operation.

[0004] In addition, during the installation process, if there is any looseness, the already positioned product is likely to shift due to the screws not being fastened in time, resulting in additional adjustment work and further extending the installation time. At the same time, frequent bending over to pick up screws puts a heavy burden on the user's waist, and long-term operation may cause health problems such as strain and fatigue. Therefore, the existing technology lacks a structure that can pre-install screws and simplify the installation process. This structure can effectively reduce the user's unnecessary movements during the installation process, improve installation efficiency, and reduce harm to the user's body. Therefore, it is necessary to make further improvements. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a hinge installation screw pre-installation structure with a simple structure and easy use. By pre-installing the screws in the product components, the user can avoid the operation of frequently bending over to remove the screws during assembly, simplifying the installation process, improving efficiency, and reducing the user's physical strain caused by repetitive movements.

[0006] The purpose of the utility model is achieved in the following way: a hinge mounting screw pre-installed structure, which includes a base, a mounting hole is opened in the middle of the base, and a fixing screw is pre-installed in the mounting hole. A first hook and a second hook are extended outward on both sides of the base, and the first hook and the second hook are installed on the hinge cup to connect the mounting hole of the base with the fixing hole on the hinge cup.

[0007] Furthermore: the base is cylindrical, and the mounting hole is located at the center of the base; the first hook and the second hook are arranged on the cylindrical surface of the base.

[0008] Furthermore: the mounting hole is a waist-shaped hole.

[0009] Furthermore, the minor axis diameter of the waist-shaped hole is smaller than the nominal diameter of the fixing screw.

[0010] Furthermore, the base, the first hook and the second hook are integrally injection-molded from plastic material.

[0011] Furthermore: a tearing groove is provided on the cylindrical surface of the base, and the tearing groove extends along the axial direction of the base.

[0012] Furthermore: the hinge cup is provided with bayonet grooves corresponding to the positions of the first hook and the second hook.

[0013] The beneficial effects of the utility model are: 1. Simple structure, low production cost and improved market competitiveness.

[0014] 2. By pre-installing the fixing screws in the mounting holes of the base, users no longer need to remove the screws individually during installation, reducing the number of screw removal steps and significantly simplifying the installation process. This design improves installation efficiency, especially when multiple screws need to be installed, and can effectively reduce user operation time.

[0015] 3. The first and second hooks on either side of the base can be hooked directly onto the hinge cup and docked with the hinge cup's fixing holes for quick installation. This hook-to-hinges design not only simplifies and swifts docking, but also ensures the stability of the base and hinge cup during installation, preventing product misalignment due to loose screws.

[0016] 4. The hook and the bayonet groove on the hinge cup cooperate to form a stable self-positioning structure. This structural design makes the installation process more stable. Even if the screws are not fully tightened, the base and hinge cup can maintain the correct position and are not prone to position deviation, greatly improving the accuracy and stability of installation.

[0017] 5. A tearing groove extending along the axial direction is provided on the cylindrical surface of the base. When the fixing screws are screwed to the plate, the tearing groove is stretched outward by the fixing screws to remove the base and facilitate the installation of the fixing screws.

[0023] The present invention is further described below in conjunction with the accompanying drawings. A hinge mounting screw pre-installed structure includes a base 1, a mounting hole 2 defined in the center of the base 1, a fixing screw 3 pre-installed in the mounting hole 2, and a first hook 4 and a second hook 5 extending outward from both sides of the base 1. The first hook 4 and the second hook 5 are hooked and mounted on a hinge cup 6, so that the mounting hole 2 of the base 1 is aligned with the fixing hole 7 on the hinge cup 6.

[0024] In one embodiment, the base 1 is cylindrical, and the mounting hole 2 is located at the center of the base 1 ; the first hook 4 and the second hook 5 are arranged on the cylindrical surface of the base 1 .

[0025] In one embodiment, the mounting hole 2 is a waist-shaped hole.

[0026] In one embodiment, the minor axis diameter of the waist-shaped hole is smaller than the nominal diameter of the fixing screw 3 .

[0027] In one embodiment, the base 1 , the first hook 4 and the second hook 5 are integrally injection-molded from a plastic material.

[0028] In one embodiment, a tearing groove 8 is provided on the cylindrical surface of the base 1 , and the tearing groove 8 extends along the axial direction of the base 1 .

[0029] In one embodiment, a bayonet groove 9 is provided on the hinge cup 6 at positions corresponding to the first hook 4 and the second hook 5 .

[0030] Working Principle: The base of this structure features a mounting hole in the middle, into which the fixing screws are pre-installed. A first hook and a second hook are located on either side of the base. These hooks snap into place in the corresponding notches on the hinge cup to achieve initial docking. The pre-installed screws eliminate the need for frequent bending to retrieve the screws during installation; users can simply turn the screws to complete the connection, improving installation efficiency.

[0031] Among them, a tearing groove is provided on the cylindrical surface of the base in the axial direction. When the user pre-inserts the screw into the mounting hole of the base and screws it to the plate through the screw, the fixing screw will be gradually tightened. When the screw is screwed to the plate, the screwing-in and tightening force of the fixing screw will generate an outward supporting force, and at this time the tearing groove begins to play a role. The purpose of the tearing groove design is to use the outward supporting force of the fixing screw after the screw is fixed in place to open or expand the cylindrical surface of the base along the tearing groove direction, so that the base is gradually separated from the screw. This process realizes the automatic disassembly of the base. Through this design, the user can easily remove the base without the aid of additional tools or operations, so that the screws can be completely tightened in place. This automatic disassembly function significantly simplifies the operating steps and reduces the trouble during manual operation.

[0032] Before the base is removed, the first and second hooks are snap-fitted to their corresponding positions on the hinge cup, ensuring a secure connection between the base and the hinge cup until the screws are fully tightened. This structure prevents product deviation or loosening due to unsecured screws during installation, significantly improving installation stability and accuracy.

[0033] Among them, the mounting hole adopts a waist-shaped hole design, which allows a certain amount of adjustment space for the screw during the fixing process. After the screw is pre-installed, the user can slightly adjust the position of the screw as needed to more accurately align it with the screw hole of the plate. This design makes the installation process more flexible, effectively avoiding the installation difficulties caused by mismatched hole diameters, while ensuring that the screw can be firmly fixed in the end. At the same time, the minor axis diameter of the waist-shaped hole is smaller than the nominal diameter of the fixing screw 3. The waist-shaped hole is used to clamp and position the fixing screw to prevent the fixing screw from loosening from the base.

[0034] The base and hook are integrally injection-molded from a plastic material, ensuring the overall strength and durability of the structure. This plastic material not only reduces production costs but also prevents components from loosening or breaking during installation. This design makes the structure more durable and easier to manufacture.

[0035] Compared to traditional techniques, in this case, once the screws are screwed into place, the force of the fixing screws gradually opens the base through the tearing groove, ultimately achieving automatic disassembly of the base, allowing the user to easily complete the process without additional operation. This design significantly reduces the number of steps required during installation and improves installation efficiency.

[0036] At the same time, the hook and hinge cup are locked together, ensuring the base remains firmly connected before the screws are tightened, preventing the product from shifting or loosening during installation. This stable hook design ensures stable and accurate installation after the screws are pre-installed.

[0037] Furthermore, the pre-installed screws and automatic disassembly design significantly reduce the user's tedious installation operations, eliminating the need to frequently bend over to pick up screws, alleviating back strain and effectively reducing the risk of physical strain from repetitive movements. This makes the installation process more efficient and convenient, while also improving the product's installation stability and resolving many of the shortcomings of existing technologies.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
