Description

Technical Field

[0001] The utility model relates to the technical field of hinge assembly, and in particular to a pre-pressing assembly mechanism of a hinge. Background Art

[0002] A hinge is a mechanical device used to connect two relatively independent solid bodies, enabling relative rotation between them. Hinges are commonly used as connectors for furniture doors, utilizing the principle of a living hinge to allow the door to open and close around an axis. Current hinge manufacturing requirements are increasingly demanding, requiring the assembly of numerous hinge components to create a finished hinge. A hinge primarily consists of a cup head, rocker arm, arm body, base, staples, inner bar assembly, torsion spring, plastic tube, and several connecting staples and screws.

[0003] A hinge with a 90-degree opening angle, which holds the two door panels parallel at 180 degrees when closed, and a 90-degree opening angle, can be used in cabinets with two consecutive doors connected in parallel, or in cabinets with a fixed door panel at one end. It is also widely used to connect corner cabinet doors to the inner cover. Before hingedly securing the cup head and arm assembly of this hinge and other high-angle hinges, the arm assembly's torsion springs and laminated plates must be moved to a preset position, aligned with the cup head's connection hole, and then hinged with U-shaped nails.

[0004] Therefore, it is necessary to design a torsion spring preload assembly mechanism suitable for large-angle hinges. Utility Model Content

[0006] In order to solve the above technical problems, an embodiment of the present utility model provides a pre-stressed assembly mechanism for a hinge, which has a carrier for accommodating the hinge, and also includes a torsion spring strip that can be raised and lowered above one side of the carrier, a torsion spring strip block and a top block that can be telescopically slidably arranged on the other side of the carrier; the torsion spring strip is used to extend into the gap between the hinge laminations and the torsion spring, and pry the end of the torsion spring to expose it from the carrier; the torsion spring strip block continues to slide to move the end of the torsion spring to a preset position; the top block is used to push the torsion spring limit block of the carrier, so that the torsion spring limit block limits the end of the torsion spring to a preset position.

[0007] Furthermore, the torsion spring selector bar can be swingably arranged in a slide groove, and the torsion spring selector bar has an inclined surface. The laminate rotates along the inclined surface toward the tail of the hinge, and the torsion spring selector bar continues to extend below the end of the torsion spring. The torsion spring selector bar descends along the slide groove, and after prying the end of the torsion spring upward, the torsion spring selector bar resets and retracts.

[0008] Further, the torsion spring dial block extends into the hinge, and the end of the torsion spring is pushed towards the head of the hinge to a preset position.

[0009] Further, the torsion spring dial block has an extension part, the extension part is flat, and when the extension part abuts against the upper side of the end of the torsion spring at a preset position, the torsion spring limiting block extends into the hinge and abuts against the lower side of the end of the torsion spring.

[0010] Further, when the torsion spring limiting block abuts against the lower side of the end of the torsion spring, the torsion spring dial block resets and retracts.

[0011] Further, it further includes a plurality of power components, and the plurality of power components are respectively used to drive the torsion spring bar, the torsion spring dial block and the top block.

[0012] Implementing the embodiments of the present invention has the following beneficial effects:

[0013] Fix the hinge on the vehicle, the torsion spring is in the initial position, the torsion spring bar pries the torsion spring to the required height, the torsion spring dial block then dials the torsion spring to the preset position, and the top block then pushes the torsion spring limiting block of the vehicle into the hinge to fix the torsion spring at the preset position and enter the next process;

[0014] It can be applied to various types of large-angle hinges, achieving the purpose of quickly and conveniently installing the torsion spring, improving production efficiency, avoiding the appearance of defective products, and saving resources and labor costs. Description of the Drawings

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0024] like Figures 1-6 As shown, a hinge pre-stressing assembly mechanism includes a carrier 5 for accommodating a hinge 4, a torsion spring bar 1 that can be raised and lowered above one side of the carrier 5, and a torsion spring block 2 and a top block 3 that can be retracted and slidably disposed on the other side of the carrier 5. The torsion spring bar 1 is used to extend into the gap between the hinge 4's laminate 41 and the torsion spring 42, and to pry the end 421 of the torsion spring 42 out of the carrier 5. The torsion spring block 2 is used to slide and continue to move the end 421 of the torsion spring 42 to a preset position. The top block 3 is used to push the torsion spring stop block 51 of the carrier 5, so that the torsion spring stop block 51 limits the end 421 of the torsion spring 42 to the preset position. Several power components 7 are also provided, each of which is used to drive the torsion spring bar 1, the torsion spring block 2, and the top block 3. In a specific implementation, the power components 7 can be pneumatic cylinders, electric cylinders, hydraulic cylinders, etc.

[0025] like Figures 3-6 As shown, the torsion spring lever 1 is pivotally mounted within a slot 6. The torsion spring lever 1 has an inclined surface 11. The laminated plate 41 rotates along the inclined surface 11 toward the rear end of the hinge 4, creating more space. This allows the torsion spring lever 1 to continue extending below the end 421 of the torsion spring 42. The torsion spring lever 1 descends along the slot 6, prying the end 421 of the torsion spring 42 upward, and then retracts. The torsion spring block 2 extends into the hinge 4, shifting the end 421 of the torsion spring 42 toward the head of the hinge 4 to a predetermined position. The torsion spring block 2 has a flat extension 21, which helps reduce collision and compression with hinge 4 components. When the extension 21 abuts the upper side of the end 421 of the torsion spring 42 in the predetermined position, the torsion spring stop 51 extends into the hinge 4 and abuts the lower side of the end 421 of the torsion spring 42. When the torsion spring stopper 51 contacts the underside of the end 421 of the torsion spring 42, the torsion spring shifter 2 resets and retracts. The hinge 4 is secured to the carrier 5, with the torsion spring 42 in its initial position. The torsion spring shifter 1 pries the torsion spring 42 to the desired height. The torsion spring shifter 2 then shifts the torsion spring 42 to the preset position. The pusher 3 then pushes the torsion spring stopper 51 of the carrier 5 into the hinge 4, securing the torsion spring 42 in the preset position and proceeding to the next assembly step. This system can be applied to various types of large-angle hinges 4, such as those with a 180° closing angle, enabling quick and convenient installation of the torsion spring 42, improving production efficiency, preventing defective products, and saving resources and labor costs.

[0026] Certainly, the above embodiments are only for illustrating the technical concept and features of the present utility model. The purpose is to enable those who are familiar with this technology to understand the content of the present utility model and implement it accordingly, and it should not be used to limit the protection scope of the present utility model. All modifications made according to the spirit and essence of the main technical solution of the present utility model should be covered within the protection scope of the present utility model.
