Detailed Description

The invention will be explained in more detail by the following examples, which disclose the invention and are intended to protect all technical improvements within the scope of the invention.

Combine accompanying drawing 1~3 a pull-out ware, including pull-out lever 1, pull-out lever 1 has front end 11 and tail end 12, and the position department that is close to the front end on the side of pull-out lever 1 offers the through-hole that runs through another side, and the inside rotation of through-hole installs screw shaft 2, screw shaft 2 runs through and extends to the opposite side of through-hole, has cup jointed torsional spring 3 and split washer 4 outside screw shaft 2 of through-hole opposite side by inside to outside in proper order.

The draw-in groove has been seted up to the position department that the inside of through-hole corresponds torsional spring 3, the one end joint of torsional spring 3 is in the inside of draw-in groove, the other end of torsional spring 3 passes in the opening of split ring 4, split ring 4 card is on screw shaft 2, and torsional spring 3 provides elastic force for the pull-out ware and makes it be in the perk position under natural state, sets up the draw-in groove that carries out the joint to split ring 4 on the screw shaft 2, and split ring 4 card prevents that screw shaft 2 and torsional spring 3 from breaking away from pull-out pole 1 in the draw-in groove of screw shaft 2.

The whole set up to right-angled Z type structure of rising pole 1, the setting of perk of tail end 12 is convenient for press tail end 12 to rising pole 1.

The cabinet assembly shown in fig. 4 comprises a cabinet a, an electrical module B is slidably mounted inside the cabinet a, grooves are formed in the inner walls of the cabinet a on the two sides of the top end of the electrical module B, two pulling-out devices are connected to the two sides of the top end of the electrical module B, screw shafts 2 on the pulling-out devices are fixed on the electrical module B, the tops of the pulling-out devices are arranged inside the grooves, the upper portion and the lower portion of each groove are a1 above the groove and a2 below the groove, slope surfaces are arranged on the two sides of the electrical module B below the groove, and placing grooves are formed in the positions, corresponding to the pulling-out rods 1, of the two sides of the surface of the electrical module B.

Embodiment 1, when the extractor and the cabinet assembly are used, the electrical module B is inserted into the guide rail of the cabinet a, the electrical module B is pressed to move inwards until the front end 11 of the extractor enters the groove of the cabinet a, and then the tail end 12 of the extraction rod is pressed at the same time, at this time, the front end 11 is in top pressure fit with the groove a1 of the cabinet a, and under the action of the lever principle, the electrical module B moves downwards under a large force and is tightly combined with the insertion part of the cabinet a. When the unlocking is needed, the puller tilts upwards under the action of the elasticity of the torsion spring 3, the tail end 12 of the pulling rod continues to be pulled upwards, the front end 11 is in abutting fit with the A2 below the groove of the cabinet A, the electrical module B moves upwards under the action of the lever principle under a larger force, and the binding force of the plugging part is overcome to move out of the cabinet A.
