Description

Technical Field

[0001] The utility model relates to a rebounder, in particular to a structure of a rebounder. Background Art

[0002] A rebounder is a kind of furniture hardware fitting, which is used in various occasions such as opening and closing cabinet doors. When closing the door panel, the door panel is tightened in two ways. One is to cooperate with a rubber head rebounder and use the self-closing force of the hinge to tighten; the other is to cooperate with a magnetic head rebounder and a springless (self-closing force-free) hinge and use magnetic adsorption to tighten. When opening the door panel, it is specifically realized by the action of the rebounder and the instantaneous release of the accumulated elastic restoring force. Traditional rebounder products need to be strictly sized during use, and the adjustment range of the door gap is small. In addition, after long-term use, it is prone to wear or other influences, resulting in unsmooth opening and closing actions or even functional failure. Content of the Utility Model

[0021] Such as Figures 1 - 5As shown, a rebounder structure includes a telescopic rod 1, a sliding seat 2, a swing arm 3 and a fixed seat 4 arranged in sequence. The telescopic rod 1 is generally provided with soft glue for pressing at the end away from the sliding seat 2. The sliding seat 2 has a threaded end 5 and a sliding end 6 at opposite ends, respectively. The telescopic rod 1 is threadedly connected to the threaded end 5. The telescopic rod 1 is used to adjust the length through the threaded connection to adapt to different door gap distances, and the adjustment range is long. The sliding end 6 is used for sliding cooperation, and linkage is used to achieve locking and unlocking. This is the basis of the traditional technical layout, and no further elaboration or limitation is made here. Here, the sliding seat 2, the swing arm 3 and the fixed seat 4 are mainly optimized and improved.

[0022] The sliding end 6 is provided with a slideway 7 which is slidably matched with the swing arm 3. The swing arm 3 is movably connected to the fixing seat 4, and the swing arm 3 can swing in a plane, which is conducive to the sliding match to realize the movement of the tortuous path. The slide 7 is provided with an inlet and outlet 8, an inlet branch 9, a bayonet branch 10 and an outlet branch 11, and the end of the inlet branch 9, the bayonet branch 10 and the beginning of the outlet branch 11 have a first locking position 12, a second locking position 13 and a third locking position 14 respectively; there are a locked state, a stable locked state and a disengaged locked state and an elastic member 15 between the swing arm 3 and the slide 7, and the elastic member 15 always acts on the locked state, the stable locked state and the disengaged locked state; in the locked state, one end of the swing arm 3 enters the inlet branch 9 from the inlet and outlet 8, and the swing arm 3 is blocked and limited by the first locking position 12; in the stable locked state, the swing arm 3 enters the bayonet branch 10 from the inlet branch 9 through the elastic member 15, and the swing arm 3 stays at the second locking position 13; in the disengaged locked state, the swing arm 3 enters the outlet branch 11 from the bayonet branch 10, and the swing arm 3 escapes from the inlet and outlet 8 through the elastic member 15. In this embodiment, the sliding column 19 enters the slideway 7 from the inlet and outlet 8, and deviates toward the wall of one side of the inlet branch channel 9, and enters the position of the first position 12 along the wall. Then it is pulled by the elastic member 15 to enter the bayonet branch channel 10, and is stuck in the bayonet branch channel 10 to remain stable. When it is necessary to disengage, an external force is applied to make the sliding column 19 enter the third position 14, and it is naturally disengaged through the elastic member 15 and escapes from the inlet and outlet 8. It should be pointed out that the direction in which the elastic member 15 acts on the first position 12 corresponds to the entrance of the bayonet branch channel 10. And the elastic member 15 always acts indirectly on the swing arm 3, specifically, the two ends of the elastic member 15 respectively abut the ends of the fixed seat 4 and the sliding seat 2, so that the swing arm 3 has an elastic reset tendency to move away from the sliding seat 2.

[0023] The swing arm 3 has a connection end 16, a narrowing portion 17 and a movable end 18 in sequence. A sliding column 19 is provided on the end surface of the connection end 16 to slide in the slideway 7. The swing arm 3 is provided with inwardly recessed grooves 20 on both sides of the narrowing portion 17. The design of the sliding column 19 is conducive to sliding fit and convenient for assembly. The design of the groove 20 allows the swing arm 3 to have a larger rotation angle outside the fixing seat 4 during the rotation of the swing arm 3, and the range of obstruction is small.

[0024] The movable end 18 is provided with an inner hole 21, the fixed seat 4 is provided with an outer hole 22 corresponding to the inner hole 21, the fixed seat 4 is provided with a mounting groove 23 for mounting the movable end 18, and the fixed seat 4 is also provided with a fixing column 24 that penetrates the inner hole 21 and the outer hole 22. The mounting method of the fixing column 24 is efficient and reliable, ensuring stability during use and not easy to loosen. The movable end 18 is provided with an arc edge 25 at the outer edge that contacts the fixed seat 4, and the inner wall of the mounting groove 23 is provided with an arc surface corresponding to the arc edge 25. The arc surface and the arc edge 25 can reduce friction during the rotation process and improve the smoothness of use.

[0025] The sliding seat 2 and the fixed seat 4 are provided with positioning blocks 26 evenly spaced along the circumferential direction, and also include a housing 27 fixed outside the sliding seat 2 and the fixed seat 4. The positioning blocks 26 enable quick positioning during installation, which is beneficial to improving structural stability. The slideway 7 also has an inlet and outlet cavity 28, and the inlet and outlet 8 are connected to the inlet and outlet cavity 28. The inlet and outlet 8 are arranged on the side of the second clamping position 13 close to the first clamping position 12, ensuring that the sliding column 19 smoothly enters the inlet branch 9 when entering.

[0026] The bayonet branch 10 is in a V-shaped structure, and the wall surface of the inlet branch 9 on one side close to the outside of the sliding seat 2 is in an arch bridge structure. This shape constitutes a stable guiding function and a locking function, and is used in conjunction with the elastic member 15. It should be noted that the elastic member 15 is mostly a spring. The locking position 12 and the locking position 3 14 are semicircular grooves, and the locking position 2 13 is the bending corner of the bayonet branch 10. In addition to limiting, the groove also has a positioning function, which is conducive to ensuring that the force direction of the elastic member 15 is opposite to the next entrance. In this embodiment, the inlet branch 9, the bayonet branch 10 and the outlet branch 11 can only move in a cyclic sequence.

[0027] The outlet branch 11 is a curved straight road with an angle greater than 90 degrees, which is mainly used for escape and unlocking, without the need for complex structural obstructions, and at the same time, it is necessary to quickly guide to the position of the inlet and outlet 8. The inlet and outlet cavity 28 has a wide surface 29 and a narrow surface 30 on the cavity wall, and the narrow surface 30 is arranged on the side close to the inlet and outlet 8. The sliding seat 2 has a hollow portion 31 between the wide surface 29 and the outlet branch 11. The positions of the wide surface 29 and the narrow surface 30 correspond to the position deviation of the inlet and outlet 8, which plays a good guiding role, and the wide surface 29 and the narrow surface 30 are non-planar and have a certain curvature. The hollow portion 31 can strengthen the local structural strength and is conducive to improving the service life. The bayonet branch 10 is provided with a guide slope 32 on the side wall close to the locking position three 14, which further improves the guiding accuracy of the movement of the sliding column 19, so that it can smoothly enter the locking position three 14.
