Description

Technical Field

[0001] The utility model relates to the technical field of hinges, and particularly relates to a novel hinge. Background Art

[0002] A hinge is usually formed by riveting or screwing multiple components such as an arm body, a base, a cup head, a four-hole component, etc. There are also tiny parts such as springs, plastic round tubes, U-shaped nails at the joints of each component. For a hinge with a buffering function, an inner strip component such as an oil pipe, a stack of sheets, and a triangular part needs to be further installed. The tail end of the oil pipe is hinged to the arm body by a connecting nail, the tail ends of the stack of sheets and the telescopic end of the oil pipe are respectively hinged to the triangular part, and finally the head end of the stack of sheets is hinged to the cup head by a U-shaped nail to form a hinge with a buffering function. However, the hinged parts of this structure are complex, which not only greatly increases the cost of the hinge, but also increases the assembly process of the hinge, making the time required to assemble the hinge longer. Content of the Utility Model

[0003] The technical problem to be solved by the embodiments of the utility model is to provide a novel hinge, which simplifies the structure of the hinge, reduces the assembly process, and lowers the production cost.

[0004] To achieve the above object, the utility model discloses a novel hinge, which includes an arm body, a cup head, a four-hole component, and an inner strip component. The inner strip component is arranged on the arm body, and the head ends of the four-hole component and the inner strip component are hinged to the cup head by a U-shaped nail. The tail end of the four-hole component is hinged to the head end of the arm body by the first connecting nail.

[0005] The inner strip component includes a stack of sheets, a damping tube, and a damping seat. The damping seat is arranged inside the head end of the arm body. The damping tube is inserted into the damping seat, and the telescopic end of the damping tube extends out of the damping seat and abuts against the first connecting nail. The head end of the stack of sheets is hinged to the cup head, the tail end of the stack of sheets is hinged to the head end of the arm body, and a pull tab is arranged at the tail end of the stack of sheets. One side of the damping seat facing the stack of sheets has a slot, so that the pull tab of the stack of sheets is inserted into the slot of the damping seat. When the hinge is closed, the stack of sheets rotates and pushes the damping seat to move towards the direction of the first connecting nail through the pull tab, so that the hinge slows down the closing speed under the resistance of the damping tube.

[0006] Furthermore, the inner strip component further includes a decorative piece, and the decorative piece covers the damping seat and is fixedly connected to the arm body.

[0007] Furthermore, clamping portions are arranged on both sides of the head end of the decorative piece, and clamping grooves are formed on the clamping portions, so that the clamping portions are buckled on the second connecting nail on the stack of sheets through the clamping grooves.

[0008] Furthermore, a stepped surface is provided in the middle of the arm body, and the end of the base abuts against the stepped surface.

[0009] Furthermore, it further includes a base. A first slot is provided at the head end of the base, and a locking member is provided on the arm body. The first slot is in snap-fit with the locking member, and the base is fixedly connected to the arm body by rotating the locking member.

[0010] Furthermore, it further includes a torsion spring. The torsion spring is arranged on the first connecting pin of the arm body. One end of the torsion spring abuts against the cup head, and the other end abuts against the second connecting pin.

[0011] Furthermore, the damping seat and the decorative piece are made of plastic material.

[0019] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] Refer to Figure 1 , Figure 2As shown in the figure, a new type of hinge includes an arm body 1, a base 2, a cup head 3, a four-hole part 4, and an inner strip assembly 5. The tail end of the four-hole part 4 is hinged to the head end of the arm body 1 through a first connecting pin 7. The base 2 is fixedly arranged at the end of the arm body 1. The inner strip assembly 5 is arranged on the arm body 1, and the head end of the inner strip assembly 5 and the head end of the four-hole part 4 are respectively hinged to the cup head 3 through a U-shaped pin 9.

[0021] Combined with Figures 3 - 5 As shown in the figure, specifically, the inner strip assembly 5 includes a laminated sheet 51, a damping tube 52, a damping seat 53, and a decorative sheet 54. The damping seat 53 is arranged at the head end of the arm body 1. The damping seat 53 has a receiving cavity inside. The damping tube 52 is inserted into the receiving cavity of the damping seat 53, and the telescopic end 521 of the damping tube 52 extends out of the receiving cavity of the damping seat 53 and abuts against the first connecting pin 7 of the arm body 1. The tail end 512 of the laminated sheet 51 is hinged to the head end of the arm body 1 through a second connecting pin 8, and the head end 511 of the laminated sheet 51 is hinged to the cup head 3 through a U-shaped pin 9. On both sides of the head end of the decorative sheet 54, there are clamping parts, and the clamping parts have clamping grooves 541, so that the clamping parts are buckled on the second connecting pin 8 on the laminated sheet 51 through the clamping grooves 541, so that the decorative sheet 54 covers the damping seat 53, and on both sides of the middle part of the decorative sheet 54, there are arc-shaped recesses, so that after the decorative sheet 54 covers the damping seat 53, a third connecting pin passes through the arc-shaped recesses and is fixedly connected to the arm body 1, thereby restricting the damping seat 53 from swinging and getting dislocated, and improving the stability of the damping seat.

[0022] Referring to Figure 2 As shown in the figure, a torsion spring 6 is arranged on the first connecting pin 7. One end of the torsion spring 6 abuts against the four-hole part 4, and the other end abuts against the second connecting pin 8, thereby using the torsion spring 6 to provide damping and resilience for the hinge.

[0023] Combined with Figure 3 As shown in the figure, further, on one side of the damping seat 53 facing the laminated sheet 51, there is a slot 531. A pull tab 514 is arranged on the tail end 512 of the laminated sheet 51, so that after the laminated sheet 51 is hinged to the arm body 1, the pull tab 514 of the laminated sheet 51 is inserted into the slot 531. When the laminated sheet 51 rotates, the damping seat 53 is pushed to slide along the arm body 1 through the pull tab 514.

[0024] Compared with the traditional hinge, the structure of the hinge in this embodiment is simplified. There is no need to connect the damping tube 52, the damping seat 53 with the arm body 1 and the laminated sheet 51. The quick connection can be realized by using the pull tab 514 on the laminated sheet 51 and the slot 531 of the damping seat 53. And in this embodiment, the damping seat 53 and the decorative sheet 54 are made of plastic materials, which not only reduces the assembly process of the hinge, but also effectively reduces the cost of the hinge.

[0025] Referring to Figures 1 - 5As shown, during specific operation, when the hinge is closed, the arm body 1 drives the four-hole part 4 to rotate counterclockwise by 90° around the U-shaped nail 9 of the cup head 3, thereby driving the lamination 51 to rotate around the second connecting nail 8. As a result, the arm body 1 returns under the elastic action of the torsion spring 6, and the damping seat 53 is pushed by the lamination 51 to move towards the first connecting nail 7, so that the telescopic end 521 of the damping tube 52 abuts against the first connecting nail 7. In this way, the closing speed of the hinge is slowed down by the resistance of the damping tube 53, making it close slowly and smoothly, reducing the impact force, and prolonging the service life of the hinge.

[0026] When the hinge is opened, the arm body 1 drives the four-hole part 4 to rotate clockwise around the U-shaped nail 9 of the cup head 3, thereby driving the lamination 51 to rotate around the second connecting nail 8, and pushing the damping seat 53 away from the first connecting nail 7 through the lamination 51. At the same time, the opening speed of the hinge is slowed down by the elastic action of the torsion spring 6 between the arm body 1 and the cup head 3.

[0027] Refer to Figure 2 、 Figure 3 As shown, the middle part of the arm body 1 has a stepped surface 11. After the base 2 is slidably inserted into the end of the arm body 1, the end of the base 2 abuts against the stepped surface 11 to make the base 2 stay in a proper position. A first slot 21 is provided at the head end of the base 2, and a locking component 12 is provided on the arm body 1. In this embodiment, the locking component is preferably a screw, and the bottom of the locking component 12 has a cap. The width of the first slot 21 is slightly larger than the outer diameter of the locking component 12, so that the first slot 21 is in snap-fit with the locking component 12, and the cap is pressed against the base 2 by rotating the locking component 12, thereby fixedly connecting the base 2 and the arm body 1.

[0028] In addition, a second slot 13 is provided at the end of the arm body 1, and a through hole 22 is provided at the end of the base 2. The end of the base 2 and the arm body 1 are fixedly connected by passing a fixing component through the second slot 13 and the through hole 22. In this embodiment, the fixing component is preferably a rivet, making the connection between the base 2 and the arm body 1 more stable.

[0029] Of course, the above embodiments are only used to illustrate the technical concept and features of the present invention, and their purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly. It cannot be used to limit the protection scope of the present invention. All modifications made according to the spirit of the main technical solution of the present invention should be covered within the protection scope of the present invention.
