TECHNICAL FIELD
[0001] The present application relates to the technical field of furniture accessories, in particular to a rebounder for furniture. BACKGROUND
[0002] The rebounder for furniture is an accessory used when the cabinet door, drawer and other parts are required to be extremely simple and without handle. It uses the expansion and contraction of the built-in spring to realize the handle-free design. When the door is pressed, the spring is compressed, and after being released, the elastic energy can push the door to automatically rebound and complete the opening and closing. In order to provide a push rod for triggering the rebounder when the door is pressed, a certain expansion space (pressing gap) needs to be reserved to ensure normal operation. The existence of the expansion space (pressing gap) makes the cabinet door (or other opening and closing parts) actually in an incomplete closed state. Taking the cabinet door as an example, this pressing gap will cause poor flatness of the cabinet door, and especially when there are a large number of cabinet doors, the visual perception of slight inclination of the cabinet door is more obvious. At the same time, the existence of the gap makes the internal space of the cabinet door in the closed state communicate with the external space, which is easy to cause dust accumulation in the internal space. SUMMARY
[0003] The present application is to solve the problems existing in the prior art, and provides a clamp rebounder without pressing gap.
[0004] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a rebounder for furniture, characterized in that it comprises a cylindrical shell, a guide block fixed at the inner end of the cylindrical shell, a trigger rod slidingly connected in the cylindrical shell, and a stretchable rubber sheet, the trigger rod is limited in rotation with the cylindrical shell, the cylindrical shell is fixed on a cabinet body, the rubber sheet is arranged in a mounting hole formed in a cabinet door, a return spring is connected between the guide block and the trigger rod, a plurality of guide assemblies are arranged between the guide block and the trigger rod, the guide assembly comprises a guide groove arranged on the peripheral surface of the guide block and an elastic sheet fixed on the trigger rod, the inner end of the elastic sheet is provided with a guide block slidingly connected in the guide groove, the guide groove comprises an upper sliding section arranged obliquely, a lower sliding section arranged in a longitudinal direction, and a horizontal moving section arranged horizontally, the lower sliding section and the upper sliding section are respectively located on both sides of the straight line in the natural state of the elastic sheet, the end of the lower sliding section and the beginning of the upper sliding section are smoothly connected, a check protrusion is arranged between the beginning of the upper sliding section and the end of the horizontal moving section, and a limiting protrusion is arranged between the end of the horizontal moving section and the beginning of the lower sliding section.
[0005] Further, a baffle is arranged between the limiting protrusion and the check protrusion, and the baffle, the limiting protrusion and the check protrusion form a U-shaped structure for the horizontal moving section.
[0006] Further, the outer end of the guide block and the inner end of the trigger rod are each provided with a sunken groove, and the two ends of the return spring are respectively located in the two sunken grooves.
[0007] Further, the stretchable rubber sheet is mounted on the outside of an inner supporting sleeve which is inserted and fixed in the mounting hole formed on the cabinet door.
[0008] The present application sets the stretchable rubber sheet on the cabinet door, not only compensates the trigger gap of the rebounder, but also forms a pressing decoration point on the cabinet door, so that the cabinet door can be opened by pressing the stretchable rubber sheet instead of the handle, and the cabinet door has the opening feature of "electric switch" to improve the seniority. Moreover, the stretchable rubber sheet can buffer the impact of rebound, so that the cabinet door is opened softly and without jerk.
[0009] In addition, the two ends of the reset spring are sunk into the sink groove of the outer end of the guide block and the inner end of the trigger rod, which reduces the space occupation of the spring and shortens the length of the entire rebounder, so that the entire cylindrical shell can be mounted in the hole formed on the layer plate or end plate of the cabinet body to optimize the aesthetics and tidiness.
[0010] The present application completes the guidance of twice limiting and once large rebound action of the trigger rod through the meandering groove structure, and the pressing distance required for pressing the trigger rod to rebound and open the cabinet door is extremely short, only the guide block needs to pass the limiting protrusion, so that the cabinet door only needs a very small pressing gap without setting the stretchable rubber sheet.

DETAILED DESCRIPTION
[0016] The following is a specific embodiment of the present application combined with the drawings to further describe the technical solutions of the present application, but the present application is not limited to these embodiments.
[0017] As Figure 1 , Figure 2 , Figure 3 andFigure 4 As shown, it comprises a cylindrical shell 1, a guide block 2 fixed at the inner end of the cylindrical shell 1, a trigger lever 3 slidingly connected in the cylindrical shell 1, and a stretchable film 4, the trigger lever 3 is limited in rotation with the cylindrical shell 1, the cylindrical shell 1 is fixed on the cabinet body, the film is arranged in the mounting hole on the cabinet door, a return spring 5 is connected between the guide block 2 and the trigger lever 3, a plurality of guide assemblies are arranged between the guide block 2 and the trigger lever 3, the guide assembly comprises a guide groove arranged on the circumferential surface of the guide block 2 and an elastic sheet 6 fixed on the trigger lever 3, the inner end of the elastic sheet has a guide block slidingly connected in the guide groove, the guide groove comprises an upper sliding section 71 arranged obliquely, a lower sliding section 72 arranged in a longitudinal direction, and a transverse section 73 arranged transversely, the lower sliding section 72 and the upper sliding section 71 are respectively located on both sides of the straight line in the natural state of the elastic sheet, the end of the lower sliding section 72 and the first end of the upper sliding section 71 are smoothly connected, a check protrusion 74 is arranged between the first end of the transverse section 73 and the end of the upper sliding section 71, and a limiting protrusion 75 is arranged between the end of the transverse section 73 and the first end of the lower sliding section 72.
[0018] A baffle 76 is arranged between the limiting protrusion 75 and the check protrusion 74, and the baffle 76, the limiting protrusion 75 and the check protrusion 74 form a U-shaped structure for the transverse section 73. The outer end of the guide block 2 and the inner end of the trigger lever 3 are provided with a sunken groove, and the two ends of the return spring 5 are respectively located in the two sunken grooves.
