According to the cabinet door buffer, movement and stretching of the damper are adjusted through the rotating wheel, the stretching length of the sleeve can be adjusted, and therefore the buffering stroke of the cabinet door buffer can be adjusted. Therefore, when people add the buffer, the proper buffer stroke of the buffer can be easily adjusted according to the change size of the opening and closing door slot of the cabinet door, and great convenience is brought to people to add the buffer.

Description

Technical Field

[0001] The utility model relates to the technical field of buffers, in particular to a buffer used for buffering the closing of cabinet doors. Background Art

[0002] In some old-fashioned furniture, the hinges used to install cabinet doors are mostly without buffering functions, and the movement and noise when opening and closing the cabinet doors are loud and obvious. Therefore, some people will install buffers later. During the installation process, people found that there are many types of buffers for installing cabinet doors, and there are different specifications and sizes, especially the size of the hinge arm. Different hinges have different changes in the length of the hinge arm cantilever during the opening and closing process, resulting in different changes in the opening and closing door gaps of the cabinet doors. Large changes in the door gap require buffers with long buffer strokes, while small changes in the door gap require buffers with short buffer strokes. However, most of the current buffers have non-adjustable buffer strokes, and it is difficult to select specifications, which makes it difficult to adapt to the later installation of buffers. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a cabinet door buffer with adjustable buffer stroke.

[0004] The technical solution adopted to solve the above technical problems is: a cabinet door buffer, including a shell, a telescopic sleeve mounted in the shell, and a damper mounted in the sleeve, characterized in that: a rotating wheel is installed at the end of the shell, and a vortex tooth is formed on the end face of the rotating wheel, and the piston rod of the damper is connected to a sliding seat sliding in the shell, and the sliding seat is formed with turbine teeth meshing with the vortex tooth.

[0005] On the basis of the above, the rotating wheel is clamped between the sliding seat and a fixed seat, the fixed seat forms a rotating shaft for installing the rotating wheel, and the fixed seat is fixed to the shell.

[0006] A buffer pad is installed on the head of the sleeve.

[0007] On the basis of the above, the cabinet door buffer is installed and fixed by a positioning seat.

[0008] The beneficial effects brought by the use of the utility model are as follows: since the cabinet door buffer of the utility model adjusts the movement and extension of the damper through the rotating wheel, the extension length of the sleeve can be adjusted, thereby achieving adjustable buffer stroke. Therefore, when installing the buffer, people can easily adjust the appropriate buffer stroke of the buffer according to the size of the door opening and closing gap, which brings great convenience to people in installing the buffer.

[0011] Figure 3 This is a structural schematic diagram of the sliding seat in the present utility model. Specific embodiments

[0012] As Figures 1-3 shown, a cabinet door buffer includes a housing 1, a sleeve 2 telescopically sleeved in the housing 1, and a damper 3 sleeved in the sleeve 2. The damper 3 has a self-resetting function, and its cylinder body is sleeved in the sleeve 2. When the hinge drives the cabinet door to close, the cabinet door will push against the sleeve 2, and the damping force of the damper 3 causes the sleeve 2 to slowly retract into the housing 1, thereby realizing the buffered self-closing of the cabinet door. In the present utility model, a runner 4 is installed at the end of the housing 1, a scroll tooth 4.1 is formed on the end face of the runner 4, the piston rod of the damper 3 is connected to a sliding seat 5 that slides in the housing 1, and a turbine tooth 5.1 meshing with the scroll tooth 4.1 is formed on the sliding seat 5. Rotating the runner 4 can adjust the movement of the sliding seat 5, and the sliding seat 5 drives the damper to telescopically move, thereby adjusting the telescopic length of the sleeve 2, that is, adjusting the buffering stroke of the buffer.

[0013] For the convenience of processing and assembling the cabinet door buffer, the runner 4 is clamped between the sliding seat 5 and a fixed seat 6. The fixed seat 6 forms a rotating shaft 6.1 for installing the runner 4, and the fixed seat 6 is fixed to the housing 1. During installation, the damper 3 is sleeved into the sleeve 2, the piston rod is connected to the sliding seat 5, the runner 4 is sleeved onto the rotating shaft 6.1, the runner 4 is clamped by the sliding seat 5 and the fixed seat 6, and then they are all sleeved into the housing 1 until the wheel surface of the runner 4 exposes the housing 1. Finally, the fixed seat 6 is fixed to the housing 1.

[0014] To reduce the impact wear of the cabinet door panel on the sleeve 2, a buffer pad 7 is installed at the head of the sleeve 2.

[0015] For the convenience of installing the cabinet door buffer, the cabinet door buffer is installed and fixed through a positioning seat 8.
