Description

Technical Field

[0001] The utility model relates to the technical field of handles, in particular to a hidden spring-back handle. Background Art

[0002] When setting the cabinet door with an opening handle, in order to save costs, you can generally open a mounting hole on the cabinet body, install the handle, and use the handle to open the cabinet door. Directly installing an exposed handle will affect the appearance and the integrity of the cabinet door surface.

[0003] Ordinary push-to-retract parts are generally limited by metal wires. However, the handle needs to drive the cabinet door to rotate during use. If the limit is only achieved by metal wires, the metal wires may easily deform and lose their limiting function during multiple pulling processes, thereby reducing their service life. Utility Model Content

[0004] The utility model provides a hidden spring-back handle, which solves the shortcomings of the prior art that the exposed handle is not aesthetically pleasing and the service life of the push-to-retract part is short.

[0005] The utility model provides the following technical solutions:

[0006] A hidden rebound handle comprises a mounting body fixedly connected to a door body, the mounting body being provided with a cavity for accommodating a handle piece, the cavity being provided with a switching mechanism for switching the handle piece to be retracted and ejected, the switching mechanism comprising a fixed end fixedly connected to the mounting body and a movable end connected to the handle piece, an elastic piece and a limit piece being installed between the fixed end and the movable end, the limit piece being provided with a lower limit point and a upper limit point.

[0007] As a further improvement of the above scheme.

[0008] Preferably, the installation body includes a folded edge pressed on the surface of the door body, the folded edge is connected to a cylinder that penetrates the door body, the other end of the cylinder is provided with an external thread, the external thread is connected to a locking piece, and the locking piece is pressed on the other side of the door body.

[0009] Preferably, the barrel is cylindrical, and the handle is circular to match the barrel.

[0010] Preferably, the limit member includes a limit rod and a first V-shaped groove at the bottom and a second V-shaped groove at the top provided with an annular channel. One end of the limit rod is fixedly connected to the fixed end, and the other end is provided with a bending portion. The bending portion cooperates with the first V-shaped groove to form a limit at the bottom, and the bending portion cooperates with the second V-shaped groove to form a limit at the top. The limit rod switches the first V-shaped groove and the second V-shaped groove along the annular channel.

[0011] Preferably, a step is provided at the bottom of the fixed end, an inlet is provided on the step and the cylinder, a plug hole facing the axial direction is provided on the step, and one end of the limit rod is inserted into the plug hole.

[0012] Preferably, a limiting ring for limiting the limiting rod from falling off is sleeved on the step, and a limiting extension for preventing the limiting ring from falling off is formed at the end of the step.

[0013] Preferably, an extension section is provided on the upper portion of the fixed end, a slide groove is provided in the extension section, and a slide rail adapted to the slide groove is provided on the side wall of the movable end, so that the movable end can slide back and forth along the extension section without rotating.

[0014] Preferably, a block is provided at the top of the slide groove to prevent the movable end from being separated from the fixed end.

[0015] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0016] In the utility model, the handle piece is switched between the retracted and extended states by pressing the handle piece. When the bent portion of the wire limit rod is located in the first V-shaped groove, the handle piece is in the extended state. At this time, the slide rail contacts the block at the end of the slide groove, and a gap is left between the handle piece and the installation body. The door body can be pulled by operating the handle piece, and the interaction between the slide rail and the block can reduce the stress concentration at the bent portion of the wire limit rod, thereby improving the service life and aesthetics.

[0017] After pressing the handle again, the bent portion of the limit rod can enter the second V-shaped groove along the channel. At this time, the handle returns to the installation body, and the upper surface of the handle is flush with the folded edge of the installation body, and the surface of the handle and the folded edge surface form a whole, so that there are no protruding parts on the surface of the cabinet door, thereby improving the aesthetics.
