Description

Technical Field

[0001] The utility model relates to the field of turnover mechanisms, in particular to an eccentric turnover mechanism with damping. Background Art

[0002] An eccentric hinge, also known as a hinge, is a key component that connects two parts of an object and enables them to rotate relative to each other. Its applications are extremely broad, including but not limited to: cabinet doors, windows, and doors for home decoration, automotive manufacturing, car refrigerators, and industrial automation. The ability to open two connected parts by rotating relative to each other enhances ease of use, ensuring stable operation and convenient operation.

[0003] Existing eccentric flipping mechanisms, such as hinges and hinges, typically consist of two or more leaf plates connected by a pin or shaft to form a rotatable connection point. Eccentric flipping mechanisms achieve more complex motion patterns and functions by adjusting the relative position of the leaf plates or adding an eccentric structure.

[0004] However, although the existing eccentric flipping mechanism has been widely used in many fields, it still has the following defects: the hinges or hinges in the existing technology can usually achieve eccentric and flipping actions, but the existing eccentric flipping mechanism lacks an effective damping mechanism during the flipping process, which makes it difficult to generate corresponding torque during use. As a result, the flipping part is prone to generate large impact and noise when reaching the extreme position, affecting the user experience. It is also not conducive to protecting the connecting parts themselves, thereby affecting the overall service life and safety performance of the connecting parts and the eccentric flipping mechanism. Utility Model Content

[0005] The purpose of the present utility model is to solve the above defects and provide an eccentric flipping mechanism with damping to solve the technical problems that the existing eccentric flipping mechanism in the above background technology lacks a corresponding damping mechanism, which affects the user experience of the relative rotation of the connecting parts and is difficult to protect the connecting parts, thereby affecting the use.

[0006] The purpose of this utility model is achieved by the following methods:

[0007] The eccentric flip mechanism with damping includes two fixing frames and a connecting rod for connecting the two fixing frames, wherein the connecting rod is provided with more than two, a bending portion is formed in the middle portion of the connecting rod, and the two adjacent connecting rods are pivotally connected by the damping rotating shaft passing through the bending portion, and the two ends of the connecting rod are respectively formed with a first connecting arm and a second connecting arm, the first connecting arm of the connecting rod is hingedly provided with a connecting shaft, and the second connecting arm of the connecting rod is hingedly provided with a mounting shaft, the fixing frame is formed with a mounting groove by bending, and a sliding groove that is conductive to the mounting groove is opened on the fixing frame, the first connecting arm of one connecting rod is matched with the mounting groove of one fixing frame, and is connected to the sliding groove through the connecting shaft on the first connecting arm, so that the first connecting arm can slide along the sliding groove through the connecting shaft, the fixing frame is provided with a mounting hole for connecting the mounting shaft, so that the second connecting arm of the connecting rod is matched with the mounting groove of the other fixing frame, and is connected to the mounting hole through the mounting shaft, an oil-collecting gasket is coaxially connected to the damping rotating shaft, the oil-collecting gasket presses against the bending portion of the connecting rod, and one end of the damping rotating shaft is coaxially connected with a spring washer.

[0008] Further in the above description, a connecting hole is opened on the bending part, and one end of the damping shaft passes through the oil-collecting gasket, the connecting rod and the spring gasket in sequence, and is threadedly connected through a nut, so that the connection between the damping shaft and the connecting rod generates a damping torque.

[0009] Further in the above description, the first connecting arm and the second connecting arm of the connecting rod are respectively a long arm and a short arm, so that the first connecting arm produces eccentric movement through the paired sliding of the connecting shaft and the slide groove, and more than two connecting rods are connected to the two fixed frames in an alternating manner.

[0010] Further in the above description, a fixing portion is formed on the fixing frame by bending, and a fixing hole for installation is opened on the fixing portion.

[0011] Further in the above description, the slide groove extends obliquely along the fixing frame toward the damping shaft.

[0012] Further in the above description, an angle is formed between the two fixing frames, and the eccentric flip angle of the two fixing frames is 0°-90°.

[0013] Further in the above description, a plurality of oil-collecting gaskets are provided, and the oil-collecting gaskets are pressed against both sides of the bent portion.

[0014] The beneficial effects of the present invention: the combined use of the damping shaft and the oil-collecting gasket effectively increases the damping effect when the connecting rod rotates, reduces the impact and noise caused by rapid flipping, and the oil-collecting gasket can continuously lubricate the shaft, reduce wear, extend service life, and improve user experience and equipment durability. The spring gasket coaxially connected to the end of the damping shaft close to the nut plays a role of pre-tightening and anti-loosening, effectively preventing the damping shaft from loosening during long-term use, further ensuring the stability and safety of the eccentric flipping mechanism. Through the connection between the connecting rod and the damping shaft and the fixed frame, the eccentric flipping between the two fixed frames is realized, so that the eccentric flipping mechanism can flexibly adjust the angle and position in specific application scenarios, and generate a certain damping torque through the setting of the damping shaft and the oil-collecting gasket, thereby meeting diverse usage requirements and enhancing the stability and service life of the mechanism.

DETAILED DESCRIPTION

[0021] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0022] In this embodiment, refer to Figure 1-Figure 5The eccentric flip mechanism with damping implemented in detail includes two fixing frames 100 and a connecting rod 200 for connecting the two fixing frames 100. There are more than two connecting rods 200. A bending portion 201 is formed in the middle of the connecting rod 200. Two adjacent connecting rods 200 are pivotally connected through the bending portion 201 by a damping shaft 300. A first connecting arm 202 and a second connecting arm 203 are respectively formed at both ends of the connecting rod 200. The first connecting arm 202 of the connecting rod 200 is hinged with a connecting shaft 400, and the second connecting arm 203 of the connecting rod 200 is hinged with a mounting shaft 500. A mounting groove 101 is formed on the fixing frame 100 by bending, and a sliding groove 102 that is conductive with the mounting groove 101 is opened on the fixing frame 100. The first connecting arm 202 of each connecting rod 200 is matched with the mounting groove 101 of a fixing frame 100, and is connected to the slide groove 102 through the connecting shaft 400 on the first connecting arm 202, so that the first connecting arm 202 can slide along the slide groove 102 through the connecting shaft 400. The fixing frame 100 is provided with a mounting hole 103 for installing the mounting shaft 500, so that the second connecting arm 203 of the connecting rod 200 is matched with the mounting groove 101 of another fixing frame 100, and is connected to the mounting hole 103 through the mounting shaft 500. An oil-collecting gasket 600 is coaxially connected to the damping shaft 300, and the oil-collecting gasket 600 is pressed against the bent portion 201 of the connecting rod 200. One end of the damping shaft 300 is coaxially connected to a spring washer 700.

[0023] A connecting hole 204 is provided on the bending portion 201. One end of the damping shaft 300 passes through the oil-collecting gasket 600, the connecting rod 200 and the spring gasket 700 in sequence, and is threadedly connected through the nut 800, so that the connection between the damping shaft 300 and the connecting rod 200 generates damping torque.

[0024] The first connecting arm 202 and the second connecting arm 203 of the connecting rod 200 are respectively a long arm and a short arm, so that the first connecting arm 202 produces eccentric movement through the matching sliding of the connecting shaft 400 and the sliding groove 102, and more than two connecting rods 200 are connected to the two fixing frames 100 in an alternating manner.

[0025] Specifically, the first connecting arm 202 is connected to the slide groove 102 on the fixed frame 100 through the connecting shaft 400, realizing the sliding adjustment function of the connecting rod 200 during the flipping process, and when the first connecting arm 202 is a long arm, it can realize the eccentric flipping effect, thereby increasing the flexibility and adaptability of the mechanism.

[0026] Optionally, the second connecting arm 203 of the connecting rod 200 is firmly connected to one of the fixing frames 100 by using the mounting shaft 500 to ensure the overall stability of the mechanism. The first connecting arm 202 of the connecting rod 200 is connected to the opposite fixing frame 100, so that the two fixing frames 100 can perform relative eccentric flipping actions through the first connecting arm 202 of the connecting rod 200.

[0027] The fixing frame 100 is bent to form a fixing portion 104, which is provided with a fixing hole 105 for installation. A chute 102 extends along the fixing frame 100 at an angle toward the damping shaft 300. Specifically, the chute 102 extends upward at an angle. When one fixing frame 100 is fixed, the other fixing frame 100 rotates via the damping shaft 300, and the connecting rod 200 slides along the chute 102 via the connecting shaft 400, creating a relative eccentric tilting motion between the two fixing frames 100.

[0028] Optionally, after one fixing frame 100 is fixed, the other fixing frame 100 can rotate relatively under the action of the connecting rod 200, and the fixing frame 100 can be eccentrically flipped by sliding the connecting shaft 400 along the sliding groove 102, thereby improving applicability and space utilization.

[0029] An angle is formed between the two fixing frames 100 , and the eccentric flip angle of the two fixing frames 100 is 0°-90°. An oil-collecting gasket 600 is provided, and the oil-collecting gasket 600 presses against both sides of the bent portion 201 .

[0030] Specifically, in this embodiment, six connecting rods 200 are provided, seven oil-collecting gaskets 600 are provided, and the seven oil-collecting gaskets 600 are sequentially spaced and pressed against the bent portion 201 of the connecting rod 200 . Three spring washers 700 are provided.

[0031] The specific usage principle in this embodiment is:

[0032] The six connecting rods 200 are spaced apart by oil-collecting washers 600, and the damping shaft 300 passes through the oil-collecting washers 600, the connecting rods 200 and the spring washers 700 in sequence, and is threadedly connected with the nuts 800. The six connecting rods 200 are divided into three groups, that is, forming two groups. The first connecting arms 202 of the two groups of connecting rods 200 extend to the left and right sides respectively, so that the first connecting arm 202 of the first group of connecting rods 200 is connected to one of the fixing frames 100, and the first connecting arm 202 of the second group of connecting rods 200 is connected to the other fixing frame 100, that is, the second connecting arm 203 of the first group of connecting rods 200 is connected to the relative fixing frame 100 through the mounting shaft 500. The second connecting arm 203 of the second group of connecting rods 200 is connected to the mounting hole 103 of the opposite fixing frame 100 through the mounting shaft 500, so as to form a staggered installation connection. The eccentric flipping between the two fixing frames 100 is achieved by connecting the connecting rod 200 and the damping shaft 300 to the fixing frame 100, so that the eccentric flipping mechanism can flexibly adjust the angle and position in a specific application scenario, and generate a certain damping torque through the setting of the damping shaft 300 and the oil-collecting gasket 600, thereby meeting diverse usage requirements and enhancing the stability and service life of the mechanism.

[0033] The difference between this embodiment and the prior art lies in that the combined use of the damping shaft 300 and the oil-collecting gasket 600 effectively increases the damping effect when the connecting rod 200 rotates, reduces the impact and noise caused by rapid flipping, and the oil-collecting gasket 600 can continuously lubricate the shaft, reduce wear, extend service life, and improve user experience and equipment durability. The spring gasket 700, which is coaxially connected to the end of the damping shaft 300 near the nut 800, plays a role of pre-tightening and anti-loosening, effectively preventing the damping shaft 300 from loosening during long-term use, further ensuring the stability and safety of the eccentric flipping mechanism.
