Description

Technical Field

[0001] The utility model relates to the technical field of buffer hinges, in particular to a short-arm buffer hinge that is not easily stuck. Background Technique

[0002] Traditional hinges have no buffer force when opening or closing, which is easy to damage the connection between the cabinet door and the cabinet body. Later, some merchants designed a way to add a damper to the hinge. When the hinge moves from the fully open state to the closed state, the piston rod of the damper in the hinge is gradually stretched, so that the hinge has buffer force.

[0003] At present, hinges are mainly used on wardrobes or cabinets, and the doors on wardrobes or cabinets are in the closed state most of the time, that is, the hinges are in the closed state for a long time. At this time, the piston rod of the damper in the hinge is fully stretched. At the same time, due to the gap in the assembly of the piston rod in the damper, the piston rod is easily stuck over time, resulting in difficulty in opening the hinge. For this reason, a short-arm buffer hinge that is not easily stuck is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a short-arm buffer hinge that is not easily stuck to solve the problems raised in the above background technique.

[0006] The buffer assembly includes a cylinder, a guide rod and a rubber block. A fixed shaft is fixedly connected inside the support. One end of the cylinder is movably sleeved outside the fixed shaft. A cavity is arranged inside the cylinder. One end of the guide rod is movably inserted into one end of the cylinder. The rubber block is fixedly connected to one end of the guide rod. A tension spring is arranged inside the cavity. One end of the tension spring is fixedly connected to one side of the rubber block, and the other end of the tension spring is fixedly connected to one end of the cavity.

Example

[0022] See also Figures 1-5 The utility model provides a technical solution: a short-arm buffer hinge that is not easy to get stuck, including a buffer hinge body 1, a support 2 is arranged on the buffer hinge body 1, a mounting frame 3 is installed at one end of the support 2, a cup holder 6 is installed at the other end of the support 2, a buffer component is arranged inside the mounting frame 3, and a limit position component is arranged inside the cup holder 6.

[0023] By setting up a buffer component, it can play a buffering role. When the cup holder 6 is closed, it can ensure that the guide rod 13 is not exposed outside for a long time, prevent the guide rod 13 from getting stuck, and avoid the situation where the buffer hinge body 1 cannot be opened. The buffer component includes a cylinder 5, a guide rod 13, and a rubber block 14. A fixed shaft 4 is fixedly connected inside the support 2. One end of the cylinder 5 is movably sleeved outside the fixed shaft 4. A cavity 12 is provided inside the cylinder 5. One end of the guide rod 13 is movably inserted into one end of the cylinder 5. The rubber block 14 is fixedly connected to one end of the guide rod 13. A tension spring 15 is arranged inside the cavity 12. One end of the tension spring 15 is fixedly connected to one side of the rubber block 14, and the other end of the tension spring 15 is fixedly connected to one end of the cavity 12. By pushing the cup holder 6 to flip, the other end of the support arm 7 rotates inside the support 2, causing the other end of the support arm 7 to push the guide rod 13 to move. The guide rod 13 drives the rubber block 14 to move inside the cavity 12. During this process, the tension spring 15 is reset inside the cavity 12, and the rubber block 14 can achieve a buffering effect.

[0024] By setting up a limit component, the position of the cup holder 6 can be limited. The limit component includes a guide post 8, a top plate 9, and a telescopic spring 10. The support arm 7 is installed inside the support 2. The guide post 8 is fixedly connected inside the cup holder 6. The top plate 9 is movably sleeved outside the guide post 8. The telescopic spring 10 is movably sleeved outside the guide post 8. One end of the telescopic spring 10 is fixedly connected to the inner side of the cup holder 6, and the other end of the telescopic spring 10 is fixedly connected to the other end of the top plate 9. A limit groove 11 is provided at one end of the support arm 7. The top of the top plate 9 is provided with an arc surface. One end of the top plate 9 abuts inside the limit groove 11. When the cup holder 6 is opened, by flipping the cup holder 6, one end of the support arm 7 rotates inside the cup holder 6, causing one end of the limit groove 11 to move outside the top plate 9. At this time, the top plate 9 is reset under the action of the force of the telescopic spring 10, making one end of the top plate 9 abut inside the limit groove 11, which can limit the position of the cup holder 6.

[0025] When the cup holder 6 needs to be closed, one end of the top plate 9 inside the cup holder 6 disengages from inside the limit groove 11, and the top plate 9 abuts against the outside of one end of the support arm 7. At this time, the telescopic spring 10 is in a compressed state.

[0026] One end of the support 2 is hinged with a connecting frame 16. The other end of the connecting frame 16 is hinged to the inner side of the cup holder 6. A first adjusting bolt 17 for adjusting the lateral distance of the cup holder 6 and a second adjusting bolt 18 for adjusting the depth of the cup holder 6 are provided on the buffer hinge body 1. By the first adjusting bolt 17 and the second adjusting bolt 18, the position adjustment of the cup holder 6 can be quickly completed, thus facilitating the use of the buffer hinge body 1.

[0027] The model of the buffer hinge body 1 is: X-08.

[0028] Working principle or structural principle: when the cup holder 6 needs to be closed, the cup holder 6 is pushed to flip. One end of the top plate 9 inside the cup holder 6 disengages from the inside of the limit groove 11, and the top plate 9 abuts against the outside of one end of the support arm 7. At this time, the telescopic spring 10 is in a compressed state. At the same time, the other end of the support arm 7 rotates inside the support 2, so that the other end of the support arm 7 pushes the guide rod 13 to move. The guide rod 13 drives the rubber block 14 to move inside the cavity 12. During this process, the tension spring 15 is reset inside the cavity 12. In the case where the cup holder 6 is closed, it is ensured that the guide rod 13 will not be exposed outside for a long time, which can prevent the guide rod 13 from getting stuck and avoid the situation where the buffer hinge body 1 cannot be opened.

[0029] When the cup holder 6 is opened, the cup holder 6 is flipped. One end of the support arm 7 rotates inside the cup holder 6, so that one end of the limit groove 11 moves to the outside of the top plate 9. At this time, the top plate 9 is reset under the action of the force of the telescopic spring 10, so that one end of the top plate 9 abuts against the inside of the limit groove 11, which can limit the position of the cup holder 6. At the same time, the other end of the support arm 7 pulls one end of the guide rod 13 to move. One end of the guide rod 13 drives the rubber block 14 to move inside the cavity 12 and pulls one end of the tension spring 15 to move. The tension spring 15 is in a stretched state, which can ensure that the cup holder 6 can be quickly closed.
