Detailed Implementation

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0016] As attached Figure 1-12 As shown, the present invention provides a buffer spring assembly structure, including a buffer spring 40 and a mounting base 10. The buffer spring 40 includes a base plate 41 and a spring pressure plate 45. The spring pressure plate 45 is inclinedly disposed on the base plate 41, and the outer end of the spring pressure plate 45 is provided with a bend angle 46. The mounting base 10 is provided with a sliding groove 11, the bottom of the sliding groove 11 is provided with a snap-fit ​​groove 12, the inner side wall of the sliding groove 11 is provided with a positioning hole 13, the bottom of the substrate 41 is provided with a snap 42 that cooperates with the snap-fit ​​groove 12, and the front end of the substrate 41 is provided with a positioning protrusion 43 that cooperates with the positioning hole 13.

[0017] Specifically, when using the buffer spring 40, the buffer spring 40 is installed in the mounting base 10, which is installed on the cabinet door. One end of the hinge arm is hinged to the mounting base 10, and the end of the hinge arm near the mounting base 10 moves against the spring plate 45. The pressure applied to the end of the hinge arm by the spring plate 45 increases the rotational damping of the hinge arm. Then, the deformation of the spring plate 45 can effectively absorb external forces and buffer them, preventing external forces from triggering the hinge to rebound and causing the cabinet door to close due to accidental contact. The outer end of the spring plate 45 is set with a bend angle 46, which can improve the structural strength and also prevent it from jamming with the hinge arm.

[0018] Compared with existing technologies, when installing the buffer spring 40, it is only necessary to align the buffer spring 40 with the sliding groove 11 and push the buffer spring 40 inward so that the buckle 42 can be inserted into the mounting groove 12 and the positioning protrusion 43 can be embedded into the positioning hole 13, which effectively reduces the assembly difficulty.

[0019] Furthermore, in order to improve the buffering effect, the end of the first hinged rotating arm 30 near the mounting base 10 is provided with a buffer abutment 31. In the open state, the front end of the spring plate 45 moves against the buffer abutment 31 to restrict the rotation of the first hinged rotating arm 30 relative to the mounting base 10.

[0020] Specifically, during the cabinet door opening process, as the hinge arm swings, the buffer abutment top 31 rotates towards the buffer spring plate 40 and simultaneously presses past the front end of the spring pressure plate 45. After the cabinet door is fully opened, the front end of the spring pressure plate 45 moves against the buffer abutment top 31, forming a damping limit. At this time, when an external force touches the cabinet door, it will simultaneously drive the hinge arm to swing at a slight angle. Since the front end of the spring pressure plate 45 remains moving against the buffer abutment top 31 in this state, the external force will be further transmitted to the spring pressure plate 45, causing the spring pressure plate 45 to deform. The deformation of the spring pressure plate 45 can effectively absorb the external force and buffer it, preventing the external force from triggering the hinge to rebound and causing the cabinet door to close due to accidental contact. The spring pressure plate 45 is inclined on the base plate 41, which can better relieve the force when it is pressed.

[0021] Furthermore, in order to improve the stability of the buffer spring 40 installation, a limiting block 14 is provided above the sliding groove 11. The limiting block 14 presses against the substrate 41. Two sets of limiting blocks 14 are symmetrically arranged and are respectively opposite to the two sides of the positioning protrusion 43. When the buffer spring 40 is pressed, the limiting block 14 can provide effective support for the substrate 41.

[0022] Furthermore, two sets of spring pressure plates 45 are symmetrically arranged. The end of the base plate 41 away from the positioning protrusion 43 is provided with a pressure bearing part 44. The pressure bearing part 44 is located between the two sets of spring pressure plates 45 and extends away from the positioning protrusion 43. Similarly, when the buffer spring 40 is compressed, the pressure bearing part 44 can effectively support the base plate 41. The buckle 42 is located in the middle of the pressure bearing part 44, and the pressure bearing part 44 is U-shaped.

[0023] Furthermore, the buckle 42 is inclinedly disposed at the bottom of the substrate 41, and both the buckle 42 and the spring plate 45 are inclined toward the same side of the substrate 41, so that when the spring plate 45 is pressed, the buckle 42 is simultaneously in a downward pressing state, which can effectively prevent the buckle 42 from coming out of the mounting groove 12 and improve the overall firmness.

[0024] Furthermore, in order to reduce processing difficulty and cost, after the buffer spring 40 adopts the above structure, the base plate 41 and the pressure plate 45 can be punched and formed from a whole piece of sheet material.

[0025] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
