Embodiment 1

[0027] refer to Figure 1~3 As the first embodiment of the present invention, this embodiment provides a relay protection with an adjustment knob, a pressure plate protection device, which is characterized in that it includes a protection pressure plate body 100 , a protection assembly 200 and an adjustment assembly 300 . The protective platen body 100 includes two connecting pieces 101 . The protection assembly 200 includes an insulating box 201 and a top cover 202 . The interior of the insulating box 201 is hollow to form an accommodating space A. The insulating box 201 is sheathed outside the protective plate body 100 . Adjustment assembly 300 knob 301, transmission member 302 and on-off piece 303, the knob 301 is set in the insulating box 201, one end of the transmission member 302 is connected to the knob 301, the other end is connected to the on-off piece 303, and the on-off piece 303 is connected to two Slice 101 active connections. The connecting pieces 101 are arran...

Embodiment 2

[0033] refer to Figure 4-8 , is the second embodiment of the present invention, this embodiment is based on the previous embodiment, the difference is that the transmission member 302 includes a first transmission member 302a and a second transmission member 302b. Both the first transmission part 302a and the second transmission part 302b are cylindrical shafts, which are rotatably connected to the bottom of the insulating box 201, that is, the shaft of the first transmission part 302a is fixed and can only rotate around the shaft. The first transmission member 302a and the second transmission member 302b are matched by gears, and the second transmission member 302b is threadedly connected with a third transmission member 302c, that is, when the second transmission member 302a rotates, the third transmission member 302c can move relative to the second The transmission member 302b moves up and down. The third transmission member 302c is movably connected with the on-off piece...

Abstract

The invention discloses a relay protection pressing plate protection device with an adjusting knob, which comprises a relay protection pressing plate protection device body with an adjusting knob, and the device body comprises a protection pressing plate body, a protection assembly and an adjusting assembly. The protection pressing plate body comprises two connecting pieces. The protection assembly comprises an insulation box and a top cover, the interior of the insulation box is hollow to form a containing space, the insulation box is arranged outside the protection pressing plate body in a sleeving mode, and the top cover is hinged to the insulation box. The adjusting assembly comprises a knob, a transmission part and an on-off piece, the knob is arranged in the insulation box, one end of the transmission part is connected with the knob, the other end of the transmission part is connected with the on-off piece, and the on-off piece is movably connected with the two connecting pieces. Through the arrangement of the protection pressing plate protection device, switching operation can be conveniently carried out under the condition that the protection device is not opened, the switching state can be clearly seen through the rotary knob, meanwhile, the protection pressing plate is in a disconnected state when the top cover is opened for maintenance, and the safety of an operator is guaranteed.

Description

technical field [0001] The invention relates to the technical field of protection pressure plates, in particular to a relay protection pressure plate protection device with an adjustment knob. Background technique [0002] Various types of protective devices in power production are equipped with protective pressure plates, which are used for outlet tripping or closing switches, and related protection functions, such as switching on and off. The existing protective pressing plate is generally exposed, which is easy to cause accidents due to misoperation. The existing protective plate protection device only adds a shell, which is very inconvenient when it is necessary to perform throwing and withdrawing operations, and when the shell needs to be opened for maintenance. Contents of the invention [0003] The purpose of this section is to outline some aspects of embodiments of the invention and briefly describe some preferred embodiments. Some simplifications or omissions ma...
