The specific embodiment

Referring to Fig. 1～6, the utility model embodiment 1 comprises a box 1, base 2, lever actuated sheet 3, the sheet 4 that is rotationally connected, two triangular form connector 8, torsion spring 5, damper 6 and door lid 24; Door box 1, base 2, the lever actuated sheet 3 and the sheet 4 hinged composition double rocker mechanisms that are rotationally connected; The two ends of described torsion spring 5 are supported on be rotationally connected sheet 4 and base 2 respectively; Described damper 6 has damper urceolus 9 and damper iron core 10, has through hole 11, one damper pilot pins 12 to pass through hole 11 in damper urceolus 9 rear ends damper 6 is hinged in the base 2; Lever actuated sheet 3 is overlapped by the sheet metal more than 2 and builds up, one lever actuated sheet pilot pin 13 is packed in lever actuated sheet 3 in the base 2, described pair of triangular form connector 8 is made up of 2

triangular form connectors

19,2 triangular form connectors 19 have anterior angle through hole 13, relief angle through hole 14 and inferior horn through hole 15, the inferior horn through hole 15 of two triangular form connectors 8 is installed with bearing pin and is supported in the base 2, and the damper iron core 10 of relief angle through hole 14 and damper 6 is connected; Two anterior angle through holes 13 on two triangular form connectors 8 are run through at the two ends of bearing pin 17 respectively, and torsion spring 5 is rotatably connected in the base 2 by lever actuated sheet 3 single needles.Each parts is a front end near an end of door box 1 in the present embodiment, and each parts is the rear end away from an end of door box 1.

Referring to Fig. 1～6, the middle upper portion of the lever actuated sheet 3 of embodiment 1 offers intermediate throughholes 19, and the front end of lever actuated sheet 3 is provided with fastens rod through-hole 20; Article 2, the intermediate throughholes 19 of lever actuated sheet 3 is installed with lever actuated sheet pilot pin 7, the two end supports of the lever actuated sheet pilot pin 7 that is installed with on the intermediate throughholes 19 is on the two side of base 2, article 2, the rod through-hole 20 of fastening of lever actuated sheet 3 is connected with door box 1 by U type crosspointer 21 1 pins, and U type crosspointer 21 another pins pass sheet 4 one ends that are rotationally connected; There is prong 16 lever actuated sheet 3 rear ends, prong 16 always and the bearing pin on the anterior angle through hole 13 of two triangular form connectors 8 17 be connected.

Referring to Fig. 1～7, Fig. 9～10, base 2 front ends of embodiment 1 stretch out the sheet 4 that is rotationally connected, the torsion spring 5 and sheet 4 lower ends that are rotationally connected are installed with a lever actuated sheet single needle 22, sheet 4 upper ends that are rotationally connected are installed with U type crosspointer 21, and the two end supports of the U type crosspointer 21 that is installed with on sheet 4 upper ends that are rotationally connected is on the two side of door box 1.The two end supports of the lever actuated sheet single needle 22 that is installed with on the torsion spring 5 is on the two side of base 2 front ends, the end that torsion spring 5 extends is by lever actuated sheet pilot pin 18 roof pressures on the intermediate throughholes 23 of lever actuated sheet 3, and the other end that torsion spring 5 extends is rotated bayonet socket 23 roof pressures of brace 4.

Referring to Fig. 1, Fig. 3, the cabinet door is in open mode, damper iron core 10 fully moves into the rear portion of damper urceolus 9, because the end that torsion spring 5 extends is by lever actuated sheet pilot pin 7 roof pressures on the intermediate throughholes 19 of lever actuated sheet 3, the other end that torsion spring 5 extends is rotated bayonet socket 23 roof pressures of brace 4.This time base 2 and the sheet 4 that is rotationally connected the angle maximum, torsion spring 5 fully opens.
