Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a spring-type damping buffer mechanism and a buffer hinge support. Background Technology

[0002] Hinges are widely used in the opening and closing of home appliances and some small devices, and their structural performance and reliability are very important for improving the quality of equipment products.

[0003] In traditional buffer hinges, the automatic closing power component is the key component of the hinge, and its performance directly determines the quality of the hinge. In order to realize its function, the automatic closing power component is composed of multiple components such as cam, roller, swing rod and elastic transmission rod group. It has certain defects: complex structure, difficult installation during production and processing, and high maintenance cost once the hinge fails. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model proposes a spring-loaded damping buffer mechanism and a buffer hinge support. This simple hinge support can achieve rapid switching of the hinge support state through the cooperation of a spring plate and a set of irregularly shaped convex shafts. Compared with traditional components with the same function, it has a simple structure, is easy to install, and has low cost.

[0005] A spring-loaded damping buffer mechanism includes a first link and a second link whose heads are rotatably connected by a pin. The head of the first link is engaged with a set of spring plates, which are curved in an arc shape. The head of the second link has an arc-shaped protrusion integrally formed on one side of the spring plates. The head of the first link has arc-shaped recesses on both sides of the arc-shaped protrusion. The arc-shaped recesses cooperate with the spring plates to achieve the positioning of the first link and the second link.

[0006] As a preferred embodiment of the above technical solution, the arc-shaped recess includes an arc-shaped recess one and an arc-shaped recess two. When the spring sheet abuts against the arc-shaped recess one, the spring-type damping buffer mechanism is in a folded and retracted state. When the spring sheet abuts against the arc-shaped recess two, the spring-type damping buffer mechanism is in an unfolded state.

[0007] As a preferred embodiment of the above technical solution, one end of the connecting rod is provided with a set of positioning holes for positioning the spring sheet, and the spring sheet can slide along the positioning holes when the arc-shaped protrusion presses the spring sheet.

[0008] As a preferred embodiment of the above technical solution, the spring sheet is made of highly elastic stainless steel.

[0009] A buffer hinge support employing any one of the above-described spring-loaded damping buffer mechanisms includes a base one and a base two. The tail of a connecting rod one is rotatably connected to the base one via a pin two, and the tail of a connecting rod two is rotatably connected to the base two via a pin three. The base one, the base two, and the connecting rod two are rotatably connected via a double-link mechanism. When the spring-loaded damping buffer mechanism is in a folded or retracted state, the double-link mechanism is housed between the connecting rod one, the connecting rod two, and the base two.

[0010] As a preferred embodiment of the above technical solution, the double linkage mechanism includes linkage three and linkage four. Linkage three is arc-shaped, and its two ends are rotatably connected to the base one and the middle section of linkage two through pin four and pin five, respectively. The two ends of linkage four are rotatably connected to the base two and the middle section of linkage three through pin six and pin seven, respectively.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The structure is simple, using a combination of spring plates, arc-shaped protrusions and arc-shaped recesses to replace traditional complex components, resulting in low manufacturing costs.

[0013] 2. Easy to install, it can effectively improve production efficiency through rapid assembly while reducing hardware costs, and it is also easy to maintain in the later stage, which can reduce maintenance costs. Attached Figure Description

Detailed Implementation

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] like Figures 1 to 3 The aforementioned spring-loaded damping buffer mechanism includes a connecting rod 2 and a connecting rod 3 whose heads are rotatably connected by a pin 1. A set of spring plates 4 are engaged at the head of the connecting rod 2. The spring plates 4 are curved in an arc shape. An arc-shaped protrusion 5 is integrally formed on one side of the spring plate 4 at the head of the connecting rod 3. Arc-shaped recesses 6 are provided on both sides of the arc-shaped protrusion 5 at the head of the connecting rod 2. The arc-shaped recesses 6 cooperate with the spring plates 4 to achieve the positioning of the connecting rod 2 and the connecting rod 3.

[0021] In this embodiment, the arc-shaped recess 6 includes an arc-shaped recess 601 and an arc-shaped recess 602. When the spring plate 4 abuts against the arc-shaped recess 601, the spring-type damping buffer mechanism is in a folded and retracted state. When the spring plate 4 abuts against the arc-shaped recess 602, the spring-type damping buffer mechanism is in an unfolded state.

[0022] In this embodiment, the head of the connecting rod 2 is provided with a set of positioning holes 7 for positioning the spring plate 4. When the arc-shaped protrusion 5 presses the spring plate 4, the spring plate 4 can slide along the positioning holes 7.

[0023] In this embodiment, the spring sheet 4 is made of highly elastic stainless steel.

[0024] like Figure 4 The buffer hinge support shown includes a base 8 and a base 9. The tail of the connecting rod 2 is rotatably connected to the base 8 via a pin 10. The tail of the connecting rod 3 is rotatably connected to the base 9 via a pin 11. The base 8, the base 9, and the connecting rod 3 are rotatably connected via a double linkage mechanism 12. When the spring-type damping buffer mechanism is in a folded or retracted state, the double linkage mechanism 12 is housed between the connecting rod 2, the connecting rod 3, and the base 9.

[0025] In this embodiment, the double linkage mechanism 12 includes a third linkage 1201 and a fourth linkage 1202. The third linkage 1201 is arc-shaped, and its two ends are rotatably connected to the base 1 8 and the middle section of the second linkage 3 via pins 4 13 and 5 14, respectively. The two ends of the fourth linkage 1202 are rotatably connected to the base 2 9 and the middle section of the third linkage 1201 via pins 6 15 and 7 16, respectively.

[0026] The difference between this application and the prior art lies in the simplification and optimization of the power components used for quickly changing the state of the buffer hinge support. This application employs a combined structure of spring plate 4, arc-shaped protrusion 5, and arc-shaped recess 6, enabling rapid switching between folded and unfolded states of the buffer hinge support. When spring plate 4 abuts against arc-shaped recess 601, the spring-type damping buffer mechanism is in the folded / retracted state; when spring plate 4 abuts against arc-shaped recess 602, the spring-type damping buffer mechanism is in the unfolded state. The structure is simple, installation is convenient, and while reducing hardware costs, rapid assembly effectively improves production efficiency. Furthermore, convenient maintenance reduces maintenance costs.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
