Referring to fig. 1-22, the working principle of the pressing type rebounding device of the present invention is:

in the process of closing the drawer, the drawer moves inward while driving the third slide rail 23 to move, and after the third slide rail 23 moves inward to a certain stroke, the third slide rail 23 drives the second slide rail 22 to move inward, so that the third slide rail 23 and the second slide rail 22 are finally retracted into the first slide rail 21.

In the above process, the three-section shifting needle 20 on the third slide rail 23 is first in a separated state from the locking groove 901 in the rebound pushing member 9, when the three-section shifting needle 20 on the third slide rail 23 contacts with the locking groove 901 in the rebound pushing member 9, the three-section shifting needle 20 drives the rebound pushing member 9 to move inward, when the rebound pushing member 9 enters the first guide groove 401 from the second guide groove 403, the rebound pushing member 9 changes from a reversed state to a horizontal state, and at the same time, the three-section shifting needle 20 completely enters the locking groove 901 in the rebound pushing member 9, the rebound pushing member 9 and the rebound trigger 8 are driven to move inward while the drawer moves inward, after the drawer moves to a limit position (either manually or through inertia), the rebound tension spring 10 drives the rebound pushing member 9 and the rebound trigger 8 to move in reverse directions, at this time, because the three-section shifting needle 20 in the third slide rail 23 cooperates with the locking groove 901 in the rebound pushing member 9, the drawer also moves outward for a certain distance; so that the end of the rebound catch 6, after disengaging from the second runner 802, will snap over the hook 806 of the locking portion 805, thereby limiting the outward movement of the rebound pusher 9 and the rebound trigger 8, so that the drawer will not move further, and the drawer is still in the closed state.

When it is necessary to open the drawer, it is only necessary to push the drawer inward, causing the drawer to drive the third slide rail 23 to move inward, thereby driving the rebounding pushing member 9 and the rebounding triggering member 8 to move inward, so that the rebounding hook 6 is separated from the hook portion 806 in the locking portion 805, and simultaneously enters the lower connecting groove 804 under the guidance of the second guiding portion 807, at this time, when the pressure applied to the drawer disappears, the drawer rebounds to open; at this time, the rebound pushing element 9 moves outward under the pulling force of the rebound tension spring 10, so as to drive the rebound triggering element 8 to move, while the rebound triggering element 8 moves, the end of the rebound hook 6 enters the first sliding groove 801 from the lower connecting groove 804 again, and when the end of the rebound hook 6 contacts with the head end of the first sliding groove 801, the rebound pushing element 9 reaches the limit position (i.e., the rebound pushing element 9 moves outward to the farthest end). In the process, the rebound pushing element 9 moves along the extending direction of the first guide groove 401, when the rebound pushing element 9 reaches the second guide groove 403, because the second guide groove 403 extends obliquely downward, and because the rebound pushing element 9 is rotatably connected to the rebound trigger 8, when the guide block at the front side of the rebound trigger 8 enters the second guide groove 403, the rebound pushing element 9 rotates around the center of the rotational connection, so that the rebound pushing element 9 turns toward the oblique direction of the second guide groove 403, so that the three-section pulling pin 20 can be disengaged from the locking groove 901 of the rebound pushing element 9, and the drawer and the slide rail assembly continue to move outward under the inertia until the slide rail assembly is fully extended, at which time the drawer is in a fully open state.

Example 2

Referring to fig. 1 to 22, the synchronous rebounding drawer of the present invention includes a drawer body, push-type rebounding devices disposed on two sides of the drawer body, and a synchronous triggering device for causing the push-type rebounding devices on two sides of the drawer body to rebound synchronously.

Referring to fig. 1 to 22, the synchronous triggering device includes synchronizers 3 disposed on the pressing type rebounding device on both sides of the drawer body and a synchronous mechanism for driving two sets of synchronizers 3 to synchronously act, where the synchronizers 3 include a synchronizer housing 301, a synchronous pushing member 12 disposed in the synchronizer housing 301, and a synchronous triggering mechanism for driving the synchronous pushing member 12 to move in a reverse direction, where a synchronous pulling pin 18 is disposed on a side surface of the third slide rail 23 close to the synchronous pushing member 12, and the synchronous pulling pin 18 extends horizontally toward the synchronous pushing member 12; a clamping groove 1201 is arranged on the synchronous pushing piece 12; the synchronous trigger mechanism comprises a synchronous trigger 13 and a synchronous tension spring 14 for driving the synchronous trigger 13 to move reversely, wherein the synchronous trigger 13 is connected to the synchronizer shell 301 in a sliding manner (a sliding block is matched with a sliding groove 303) and can move along the length direction of the synchronizer shell 301; the synchronous pushing part 12 is rotationally connected to the synchronous trigger 13, a guide mechanism for causing the clamping groove 1201 on the synchronous pushing part 12 to clamp the synchronous pulling needle 18 and to be separated from the synchronous pulling needle 18 is arranged between the synchronizer shell 301 and the synchronous pushing part 12, and the guide mechanism causes the clamping groove 1201 of the synchronous pushing part 12 to be separated from the synchronous pulling needle 18 in the drawer opening process; the guide mechanism is used for urging the clamping groove 1201 of the synchronous pushing piece 12 to be matched with the synchronous pulling needle 18 during the closing process of the drawer; one end of the synchronous tension spring 14 is connected with the synchronizer housing 301, the other end of the synchronous tension spring is connected with the synchronous trigger 13, and the pulling force of the synchronous tension spring 14 causes the synchronous trigger 13 to move towards the tail end of the synchronizer housing 301; the synchronous mechanism is used for promoting the synchronous triggering parts 13 on the two sides to synchronously move in the opposite directions.

Referring to fig. 1-22, the guide mechanism includes a first guide groove 304 provided on the synchronizer housing 301, a second guide groove 302, and a guide block provided on the synchronizing pusher 12; the first guide groove 304 and the second guide groove 302 are arranged in parallel and both extend along the length direction of the synchronizer housing 301; wherein the second guide groove 302 is located at the end of the synchronizer housing 301 and extends obliquely downward; when the guide block on the synchronous pushing part 12 enters the second guide groove 302, the clamping groove 1201 of the synchronous pushing part 12 is separated from the synchronous pulling needle 18; when the synchronous pulling pin 18 drives the guide block in the synchronous pushing member 12 to enter the first guide groove 304 from the second guide groove 302, the synchronous pulling pin 18 completely enters the clamping groove 1201. With the above arrangement, during the drawer opening process, the synchronous pulling pin 18 on the third sliding rail 23 drives the synchronous pushing member 12 to move from the first guiding groove 304 to the second guiding groove 302, and after the synchronous pushing member 12 moves to the second guiding groove 302, the synchronous pushing member 12 rotates downward around the rotation center of the synchronous triggering member 13, so that the synchronous pulling pin 18 is pulled out of the clamping groove 1201 of the synchronous pushing member 12, and thus, the third sliding rail 23 can move outward; similarly, in the process of closing the drawer, the third slide rail 23 drives the synchronous pulling pin 18 to move inward and cooperate with the clamping groove 1201 in the synchronous pushing member 12 to push the synchronous pushing member 12 to move inward, and after the synchronous pushing member 12 moves to the first guide groove 304, the clamping groove 1201 in the synchronous pushing member 12 clamps the synchronous pulling pin 18 and continues to move inward under the driving of the synchronous pulling pin 18; when the end of the rebound catch 6 engages with the locking portion 805, the synchronous pushing member 12 stops moving; at this time, the entire drawer is in a state to be triggered.

Referring to fig. 1 to 22, the synchronizing mechanism includes a synchronizing rod 24 and cams 15 disposed on both sides of the synchronizing rod 24, wherein the cams 15 are rotatably connected to the head end of the synchronizer housing 301, a torsion spring 17 is disposed between the cams 15 and the synchronizer housing 301, the torsion spring 17 is mounted on a mounting shaft of the cams 15, and the elastic force of the torsion spring 17 urges the cams 15 to return; the cam 15 is further provided with a cylindrical pin 16, the synchronous trigger 13 is provided with a chute 1301 at a position close to the head end of the synchronizer housing 301, and the chute 1301 extends obliquely upwards; when the synchronous trigger 13 moves towards the head end of the synchronizer housing 301, the cylindrical pin 16 on the cam 15 enters the inclined groove 1301; in addition, a limit structure for limiting the rotation stroke of the cam 15 is arranged on the cam 15 and the housing, and the limit structure comprises a bump 1501 arranged on the wheel surface of the cam 15 and a stop 19 arranged on the synchronizer housing 301; wherein the stopper 19 is located in the rotation track of the bump 1501. With the above arrangement, during the drawer closing process, the synchronous pulling pin 18 on the third sliding rail 23 also cooperates with the clamping groove 1201 of the synchronous pushing member 12, so as to drive the synchronous pushing member 12 and the synchronous triggering member 13 to move inwards, while during the inward movement of the synchronous triggering member 13, the inclined groove 1301 in the synchronous triggering member 13 contacts the cylindrical pin 16 on the cam 15 and causes the cylindrical pin 16 to drive the cam 15 to rotate, while the cam 15 rotates, the synchronous torsion spring 17 is gradually in a compressed state, when the bump 1501 on the cam 15 contacts the stopper 19 on the synchronizer housing 301, the cam 15 stops rotating, and at this time, the cam 15 rotates to the limit position; meanwhile, the synchronous tension spring 14 is also in an ultimate tension state; when the drawer rebounds and triggers, the inward acting force applied to the synchronous pushing member 12 disappears, the synchronous pushing member 12 and the synchronous triggering member 13 move in opposite directions (i.e., move outward) under the action of the synchronous tension spring 14, and due to the outward movement of the synchronous triggering member 13, the cylindrical pin 16 on the cam 15 can move relative to the inclined groove 1301 in the synchronous triggering member 13, so that the cam 15 is reset under the action of the synchronous torsion spring 17, and at the same time, the synchronous rod 24 connected with the installation shaft hole of the cam 15 also rotates, so that the rotation rates of the cams 15 on both sides of the synchronous rod 24 are the same; when the rotation speed of the cam 15 on one side is too fast, the cam 15 with the slower rotation speed is driven to rotate fast or the cam 15 with the faster rotation speed is limited to rotate slowly by the cam 15 with the slower rotation speed on the other side due to the existence of the synchronous rod 24; therefore, the moving speed of the synchronous triggering pieces 13 at the two sides is limited, so that synchronous triggering and synchronous rebounding of the pressing type rebounding devices at the two sides of the drawer body are ensured, and the rebounding driving force is the same.

Referring to fig. 1-22, the synchronization rod 24 is fitted over the mounting shaft of the cam 15 and the slots of the two cooperate. Through the arrangement, the two ends of the synchronizing rod 24 can be conveniently and quickly connected with the mounting shafts of the cams 15 in the pressing type rebounding devices on the two sides of the drawer body, so that the assembly efficiency can be improved, and the later maintenance and replacement are facilitated.

The above is the preferred embodiment of the present invention, but the embodiment of the present invention is not limited by the above, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be equivalent replacement modes, and all are included in the scope of the present invention.
