Description

Technical Field

[0001] The utility model belongs to the technical field of hinges, and in particular relates to a hinge with good stability. Background Art

[0002] A hinge is a common component used to connect two objects so that they can rotate relative to each other. Generally speaking, this type of hinge consists of a cup-shaped component (hinge cup) installed on the door and a hinge body installed on the cup-shaped component via a folded connecting rod component (or arm component). The hinge body is installed on the inner wall surface of a frame for storing objects such as furniture, and the connecting rod component is embedded in the cup-shaped component when the door is closed.

[0003] Traditional hinges have no buffering force when opening or closing, and are prone to damaging the connection between the cabinet door and the cabinet. Later, a method of adding a hydraulic cylinder to the hinge was designed, so that the hinge has a preliminary buffering force. However, if the user uses a large force to open or close the cabinet, a certain vibration force will be generated between the cabinet and the cabinet door and transmitted to the hinge, so that the screws on the hinge may become loose and fall off under the action of the vibration force, thereby affecting the stability of the connection between the cabinet body and the cabinet door. In view of this, the present utility model is specially proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a hinge with good stability which can overcome the above problems or at least partially solve the above problems.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is: a hinge with good stability, comprising: a hinge arm, a hinge seat and a hinge cup, the hinge seat is installed at the lower end of the hinge arm through a position adjustment component, and the hinge cup is rotatably connected to the end of the hinge arm through a rotating shaft; a torsion spring, which is sleeved on the rotating shaft, and its two ends are respectively against the hinge arm and the hinge cup; a spring yielding plate group, which is rotatably connected to the position of the hinge arm close to the hinge cup, and one end of the spring yielding plate group is rotatably connected to the hinge cup; threaded holes are provided on the hinge seat and the hinge cup, and are threadedly connected with fixing bolts, and a buffer gasket is sleeved on the screw rod of the fixing bolt.

[0006] In order to reduce or eliminate the vibration force transmitted to the fixing bolt, further, the buffer pad is a rubber buffer pad.

[0007] In order to facilitate the limiting effect on the fixing bolt, further, the buffer gasket is a metal gasket, and triangular protrusions are respectively provided on the upper and lower surfaces of the buffer gasket, and friction patterns are provided on the side of the fixing bolt that is in contact with the buffer gasket.

[0008] In order to further improve the stability between the fixing bolt and the hinge seat and hinge cup, further, a buffer damper is rotatably connected to the lower side of the hinge arm near the hinge seat, and the end of the spring positioning plate group away from the hinge cup is rotatably connected to the buffer damper.

[0009] In order to improve the overall aesthetics and prevent the fixing bolts from scratching the user's hands, further, the threaded holes of the hinge seat and the hinge cup are provided with embedding grooves, and the diameter of the embedding grooves is larger than the diameter of the bolt head of the fixing bolt.

[0010] In order to improve the supporting effect of the hinge on the cabinet door, further, the hinge seat is symmetrically provided with a plurality of threaded holes on both sides of the hinge arm.

[0011] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: the utility model provides a buffering gasket, which can buffer the fixing bolts when the switch cabinet door vibrates the hinge, thereby avoiding the problem of the fixing bolts loosening and falling off due to vibration, and effectively improving the stability between the hinge and the cabinet body and cabinet door.

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0020] Embodiment 1:

[0021] Reference Figure 1-Figure 4 A hinge with good stability comprises: a hinge arm 1, a hinge seat 2 and a hinge cup 4, the hinge seat 2 is installed at the lower end of the hinge arm 1 through a position adjustment component 3, and the hinge cup 4 is rotatably connected to the end of the hinge arm 1 through a rotating shaft; a torsion spring 5 is sleeved on the rotating shaft, and its two ends are respectively against the hinge arm 1 and the hinge cup 4; a spring yielding piece group 6 is rotatably connected to the position of the hinge arm 1 close to the hinge cup 4, and one end of the spring yielding piece group 6 is rotatably connected to the hinge cup 4; threaded holes are opened on the hinge seat 2 and the hinge cup 4, and a fixing bolt 10 is threadedly connected, and a buffer gasket 9 is sleeved on the screw rod of the fixing bolt 10.

[0022] When the cabinet door needs to be installed on the cabinet body, the hinge cup 4 and the hinge seat 2 are first installed to the designated positions on the cabinet door and the cabinet body through the fixing bolts 10, and then the hinge arm 1 rotatably connected to the hinge cup 4 can be connected to the hinge seat 2 through the position adjustment component 3. When the cabinet door is tilted during installation, the cabinet door can be adjusted horizontally through the position adjustment component 3. After the horizontal adjustment of the cabinet door is completed, the installation of the cabinet door can be completed. Among them, the fixing bolt 10 can adopt the self-tapping screws commonly seen on the market, and other components that can fix the hinge can also be adopted. Through the setting of the buffer gasket 9, when the opening and closing of the cabinet door causes vibration to the hinge, the fixing bolt 10 can be buffered to avoid the problem of loosening and falling off of the fixing bolt 10 due to vibration, thereby effectively improving the stability between the hinge and the cabinet body and the cabinet door.

[0023] Embodiment 2:

[0024] Reference Figure 1-Figure 4 , a hinge with good stability, which is basically the same as Example 1, and further: the buffer gasket 9 is a rubber buffer gasket. When the cabinet door switch generates vibration on the hinge seat 2 and the hinge cup 4, the buffer gasket 9 can buffer and offset the force generated by the vibration, reduce or eliminate the vibration force transmitted to the fixing bolt 10, thereby ensuring the fastening force of the fixing bolt 10 on the hinge, and improving the stability between the hinge and the cabinet body and the cabinet door.

[0025] Embodiment 3:

[0026] Reference Figure 1-Figure 4, a hinge with good stability, which is basically the same as Example 1, and further: the buffer gasket 9 is a metal gasket, and the upper and lower surfaces of the buffer gasket 9 are respectively provided with triangular protrusions 901, and the side of the fixing bolt 10 that is in contact with the buffer gasket 9 is provided with friction patterns. When the fixing bolt 10 rotates due to vibration, the triangular protrusion 901 and the friction patterns can limit the fixing bolt 10, and the buffer gasket 9 will also be firmly stuck with the hinge seat 2 and the hinge cup 4 under the action of the triangular protrusion 901, thereby avoiding the problem of the fixing bolt 10 loosening and falling off under the action of vibration, and effectively ensuring the stability of the hinge connection between the cabinet body and the cabinet door.

[0027] Embodiment 4:

[0028] Reference Figure 1-Figure 4 , a hinge with good stability, which is basically the same as embodiment 1, and further: a buffer damper 7 is rotatably connected to the position of the lower side of the hinge arm 1 near the hinge seat 2, and the end of the spring-displacing plate group 6 away from the hinge cup 4 is rotatably connected to the buffer damper 7. Through the setting of the buffer damper 7, a buffering effect can be played on the cabinet door to avoid vibration of the hinge when the cabinet door is opened and closed, thereby further improving the stability between the fixing bolt 10 and the hinge seat 2 and the hinge cup 4, and reducing the possibility of rotation of the fixing bolt 10.

[0029] The threaded holes of the hinge seat 2 and the hinge cup 4 are both provided with embedding grooves 8, the diameter of which is greater than the diameter of the bolt head of the fixing bolt 10, wherein the depth of the embedding groove 8 is greater than or equal to the thickness of the threaded bolt of the fixing bolt 10. Therefore, when the hinge is connected to the cabinet body and the cabinet door through the fixing bolt 10, the fixing bolt 10 can be embedded in the embedding groove 8, which can not only improve the overall aesthetics, but also prevent the fixing bolt 10 from scratching the user's hand.

[0030] The hinge seat 2 is symmetrically provided with multiple threaded holes on both sides of the hinge arm 1. By opening multiple threaded holes on the hinge seat 2, the stability of the connection between the hinge and the cabinet body can be improved, thereby improving the supporting effect of the hinge on the cabinet door and reducing the deviation of the cabinet door under the action of its own gravity.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
