Description

Mechanical elastic safety socket

Technical Field

The invention relates to the technical field of sockets, in particular to a mechanical elastic safety socket.

Background

The socket is the most common electrical element, and the switch socket is not a large part like a household appliance, but is related to household daily safety, and is the first defense line for guaranteeing household electrical safety, so that a tiger cannot be used when the switch socket is selected.

In the prior art, conventional power sockets rely on the stiffness of the flow-guiding reed to clamp the power plug. On one hand, certain friction exists between the head and the socket, so that the plug is laborious, inconvenient, unsafe and interferes with the working problems of other electrical appliances. Surrounding plugs are often inadvertently touched during the unplugging process, interfering with the operation of other appliances. At the same time, too high rigidity will cause difficulty in inserting and extracting the plug, while reducing the rigidity of the reed will cause relaxation of the reed after multiple times of insertion and extraction, and discharge spark is generated during insertion and extraction, resulting in burning loss of the socket and the plug.

The beneficial effects of the invention are as follows: compared with the prior art, the socket has the advantages that the clamping function is met through the rigidity of the reed in the traditional socket, the sliding mechanism is pushed to slide and reset through the matching mode of the pawl ratchet and the spring, so that the movable copper sheet on the sliding mechanism and the fixed copper sheet on the socket base are clamped or loosened mutually, the clamping capacity is not affected after repeated use for many times, the plug is easy, and the safety is ensured.

Drawings

Fig. 1 is a schematic structural view of a mechanical elastic safety socket provided by the invention.

The marks in the figure: the socket comprises a socket base 1, a socket upper cover 2, an end cover 3, a push rod 4, a plug jack 5, a small reset spring 6, a pawl 7, a ratchet column 8, a sleeve 9, a sliding rail 10, a sliding block 11, a swing rod 12, a movable copper sheet 13 and a fixed copper sheet 14.

Detailed Description

The invention will be further described with reference to the drawings and the specific embodiments.

As shown in fig. 1, a mechanical elastic safety socket comprises a socket upper seat and a socket base 1, wherein the socket upper seat is connected with a push rod 4, plug jacks 5 are arranged on two sides of the push rod 4, and a pawl 7 is connected to the lower part of the push rod 4; the socket base 1 is provided with a ratchet column 8 matched with the pawl 7, the ratchet column 8 is connected with a sleeve 9 in a sliding manner, and sliding mechanisms are arranged on two sides of the ratchet column 8.

The sliding mechanism is hinged to the sleeve 9 through a swing rod 12; the sliding mechanism comprises a sliding rail 10 and a sliding block 11, wherein the sliding block 11 is hinged with one end of a swing rod 12, a movable copper sheet 13 is fixedly connected to the sliding block 11, and a fixed copper sheet 14 is arranged on the socket base 1. The movable copper sheet 13 and the fixed copper sheet 14 are L-shaped, and a copper sheet slot is formed between the movable copper sheet 13 and the fixed copper sheet 14.

A guide groove is connected below the plug jack 5, and an opening of the guide groove is aligned between the movable copper sheet 13 and the fixed copper sheet 14.

The socket upper seat comprises a socket upper cover 2 and an end cover 3, the socket upper cover 2 and the socket base 1 are mutually matched, and the end cover 3 is clamped in the socket upper cover 2. A movable chamber is arranged between the end cover 3 and the upper socket seat. A plurality of small reset springs 6 are arranged in the movable cavity, and two ends of each small reset spring 6 respectively prop against the bottom of the end cover 3 and the upper socket seat. A large reset spring is arranged between the sleeve 9 and the socket base 1, and one end of the large reset spring is propped against the socket base 1.

The push rod 4 passes through the socket upper cover 2 and protrudes outside the end cover 3.

In actual use, the upper part of the socket is provided with a section of protruding push rod 4, when a plug is inserted, the push rod 4 is pushed downwards, the push rod 4 pushes the pawl 7 to slide downwards, when the socket is to be meshed, the lower pawl 7 rotates due to radial force, the lower pawl 7 is meshed with a ratchet wheel fixed on the socket to be propped against, and the lower vertically sliding sleeve 9 is driven by the downward movement of the pawl 7, so that the spring is compressed to store force. The two swing rod 12 mechanisms with equal arm lengths are hinged on the slidable sleeve 9, the other end of the swing rod 12 is hinged with the slide block 11 mechanism, therefore, the vertically slidable sleeve 9 moves downwards to drive the swing rod 12 to further push the slide block 11, the slide block 11 moves outwards along the slide rail 10 and simultaneously drives the movable copper sheet 13 on the slide block 11 to be close to the fixed copper sheet 14 on the socket base 1, so that the tensioning of the two copper sheets in the socket is realized, a larger clamping force is formed, the plug jack 5 is aligned and pointed between the two copper sheets by the guide groove, the copper sheets of the plug are firmly clamped by the two tensioned copper sheets in the socket, the guide groove simultaneously avoids the problem of uneven stress of the copper sheets of the plug, and the whole process is reliable in operation.

When the push rod 4 is pressed down again, the ratchet mechanism is meshed again and returns to the previous position, and the spring provides restoring force due to the power of the two restoring springs, and transmits the force to the push rod 4, so that the "pop-up" is realized. At this time, the slider 11 moves inwards under the action of the swing rod 12 and drives the movable copper sheet 13 to be far away from the fixed copper sheet 14, so that the clamping force between the two copper sheets is effectively reduced, the plug can be pulled out easily, and meanwhile, electric sparks are generated when the inserting plate is effectively avoided due to the fact that the two copper sheets are far away from each other, and the safety performance is improved effectively.

The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes using the contents of the specification and drawings, or direct or indirect application in other related technical fields, are included in the scope of the invention.
