Embodiment 1

[0039] Pull and insert the triangular plug labor saver, basically as figure 1 As shown, including the protective cover 1 and the base 2 located under the protective cover 1, the thickness of the base 2 in this embodiment is 1.5mm, combined with figure 2 As shown, the upper surface of the protective cover 1 is provided with a handle portion, which is a lifting ring 102, and the lifting ring 102 can be hinged, clamped or integrally formed with the top of the protective cover 1, preferably integrally formed in this implementation. The lower part of the protective cover 1 is integrally formed with several vertical panels 101, and the upper part of the base 2 is integrally formed with a number of vertical connecting columns 201. In this embodiment, there are preferably four connecting columns 201, and the side walls of the panel 101 are provided with Slots 104, the number of slots 104 on a panel 101 in this embodiment is preferably two, combined Figure 8 As shown, the panel 101 ...

Embodiment 2

[0047] The difference between the second embodiment and the first embodiment is: the combination image 3 , Figure 4 , Figure 5 As shown, the upper surface of the protective cover 1 is also bonded with a first main Velcro, the lower surface of the base 2 is bonded with a first secondary Velcro 203 that cooperates with the first main Velcro, and the outer surface of the panel 101 Both are bonded with the second main Velcro, and the upper part of the side wall of the base 2 is also bonded with several second secondary Velcro 205 that cooperate with the second main Velcro, so as to strengthen the connection between the panel 101 and the connecting column 201, and prevent the user from When in use, too much force is applied, causing the connecting column 201 and the base 2 to break, causing damage to the labor saver. combine Image 6 , Figure 7 As shown, a closing plate 3 is hinged around the bottom of the protective cover 1 . The closing plate 3 is provided with a slot hol...

Embodiment 3

[0051] The difference between the third embodiment and the first embodiment is that a bar magnet is bonded to the outer surface or the inner surface of the panel 101. In this embodiment, a bar magnet is bonded to the inner surface of the panel 101 as an example. 204 is bonded to one end of the inner surface of the panel 101 with a permanent magnet that attracts each other with the bar magnet.

[0052] The specific implementation process is as follows: when the user is using, the permanent magnet is adsorbed on the bar magnet, so that the connecting rod and the panel 101 are connected together, and the suction force of the magnet makes it difficult to slip between the connecting rod and the panel 101, thereby reaching the limit The bit protrusion 204 has the effect of anti-shedding.

Abstract

The invention relates to the field of connecting devices of basic electrical elements, in particular to a labor-saving device for pulling-out and plugging of a triangular plug. The device comprises a protective cover, a base and a handle part. The handle part is arranged on the upper surface of the protective cover. A plurality of panels are arranged on the peripheral side of the protective cover. Slots are formed in the panels. A connecting column is arranged under each panel. The connecting columns are arranged on the circumferential side of the base. The tops of the connecting columns are provided with limiting protrusions connected with the slots in a clamped mode, so that a placing cavity used for placing a triangular plug is formed between the protective cover and the base. The base is provided with inserting holes capable of allowing male plug pins of the triangular plug to penetrate through. The labor-saving device is used for connecting the electrical elements, and the electrical elements can be pulled out more easily in a labor-saving mode.

Description

technical field [0001] The invention relates to the field of connecting devices for basic electrical components, in particular to a labor saver for pulling out and inserting a triangular plug. Background technique [0002] When using electrical appliances in family life, the plug used is often a triangular plug, because the terminal of the triangular plug contains a ground wire, and the length of the ground wire is longer than that of the live wire and the neutral wire. The risk of electric leakage from the small power plug is safer for users. [0003] When using, the user needs to insert the plug into the socket, so that the male pin on the plug is connected with the line in the socket, so as to achieve the effect of circuit connection and realize the power supply of electrical appliances. And if the triangular plug is inserted into the socket for a long time, not only the risk of damage and aging of the socket will increase, but also the risk of circuit short circuit will...
