Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] see Figure 1 to Figure 4 , the pull-out type low-voltage switchgear drawer drawer labor-saving mechanism given in the figure includes a drawer 100, the drawer 100 has a drawer panel 110, and the entire drawer 100 is placed on the drawer track 200, so that the drawer 100 can be along the drawer track 200 Twitch back and forth.

[0029] A labor-saving handle insertion hole 111 is defined at a position lower than the middle part of the drawer panel 110 .

[0030] The drawer of the withdrawable low-voltage switch cabinet draws out the dodge door mechanism in the labor-saving mechanism and includes an L-shaped dodge door 310 , a door opening knob 330 , a crank arm 340 , and a connecting plate 320 whose shaft is located on the drawer panel 110 and is located in the drawer panel 110 . This L-shaped dodge door 310 has a covering portion 311 f...

Abstract

The invention discloses a drawer extraction force-saving mechanism of an extraction type low-voltage switch cabinet. The drawer extraction force-saving mechanism comprises a drawer and also comprises a force-saving handle insertion hole arranged in a drawer panel, a movable door mechanism, a rotatable door opening knob arranged on the drawer panel, a connecting lever fixed on the inner end of the door opening knob, a connecting plate, a 7-shaped force-saving handle, a baffle plate arranged in the drawer, a through hole arranged in a drawer bottom plate and a support member arranged between drawer rails, wherein the movable door mechanism comprises an L-shaped movable door arranged on the drawer panel through a shaft and positioned in the drawer panel, the L-shaped movable door is provided with a covering part used for covering the force-saving handle insertion hole and a connecting part connected with the connecting plate, one end of the connecting plate is connected with the tail end of the connecting part of the L-shaped movable door, the other end of the connecting plate is connected with the connecting lever, a force-applying groove in which the fulcrum end of the force-saving handle is inserted is arranged in the support member, and corresponds to the through hole. Compared with the drawer force-increasing mechanism in the existing extraction type low-voltage switch cabinet, the drawer extraction force-saving mechanism has the advantages of simple structure and convenience for operation.

Description

technical field [0001] The invention relates to the technical field of a withdrawable low-voltage switchgear, in particular to a pull-out labor-saving mechanism for a drawer of a withdrawable low-voltage switchgear. Background technique [0002] In the withdrawable low-voltage switchgear produced and used at present, the two contacts of the power inlet and outlet are fixed on the drawer of the device, and the connection and separation of the two contacts and the power distribution line are pushed and pulled by force. The drawer is completed with great force and vibration. If there are too many electrical components arranged in the drawer, the drawer will be heavy and cannot be pulled out. For this reason, someone has invented many kinds of drawer boosters to save the force of drawing out the drawer, but these boosters have complex structures and high costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pull...
