Description

A kind of mechanical elastic safety socket

technical field

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

Background technique

The socket is the most common electrical component. Although the switch socket is not a "big piece" like a home appliance, it is related to the daily safety of the family, and it is the first line of defense to ensure the safety of the family's electrical appliances. Therefore, you must not be sloppy when choosing a switch socket.

In the prior art, the traditional power socket relies on the rigidity of the guide reed to clamp the power plug. On the one hand, there is a certain frictional force between the head and the socket, and there are laborious plugging and unplugging, which is inconvenient, unsafe, and interferes with the work of other electrical appliances. During the unplugging process, the surrounding plugs are often touched inadvertently, which interferes with the work of other electrical appliances. At the same time, due to the high rigidity, it will be difficult to insert and pull out the plug, and reducing the stiffness of the reed will cause the reed to relax after many times of plugging and unplugging, and discharge sparks will be generated when plugging and unplugging, causing sockets and plugs to be damaged. burn out.

Contents of the invention

The technical problem mainly solved by the present invention is to provide a mechanical elastic safety socket, which realizes safe insertion and extraction by changing the clamping mode of the socket reed, and solves the problem that the reed is easy to loosen.

For solving above-mentioned technical purpose, the technical scheme that the present invention adopts is as follows:

A mechanical elastic safety socket, comprising a socket upper seat and a socket base, characterized in that: the socket upper seat is connected with a push rod, and plug sockets are arranged on both sides of the push rod, and a pawl is connected at the lower part of the push rod; The socket base is provided with a ratchet column adapted to the pawl, and a sleeve is slidably connected to the ratchet column, and a sliding mechanism is arranged on both sides of the ratchet column, and the sliding mechanism is hinged to the sleeve through a swing rod; the sliding A movable copper sheet is connected to the mechanism, and a fixed copper sheet is installed on the socket base.

Further, the sliding mechanism includes a sliding rail and a sliding block, the sliding block is hinged to one end of the swing rod, and the movable copper piece is fixedly connected to the sliding block.

Further, both the movable copper sheet and the fixed copper sheet are L-shaped, and a copper sheet slot is formed between the movable copper sheet and the fixed copper sheet.

Further, a guide groove is connected below the plug socket, and the opening of the guide groove is aligned between the movable copper sheet and the fixed copper sheet.

Further, the socket upper seat includes a socket upper cover and an end cover, the socket upper cover and the socket base are matched with each other, and the end cover is clipped into the socket upper cover.

Further, a movable chamber is provided between the end cover and the socket upper seat.

Further, a plurality of small return springs are arranged in the movable chamber, and the two ends of the small return springs respectively abut against the bottom of the end cover and the upper seat of the socket.

Further, a large return spring is provided between the sleeve and the socket base, and one end of the large return spring is against the socket base.

Further, the push rod passes through the upper cover of the socket and protrudes outside the end cover.

The beneficial effect of the present invention is: different from the situation of the prior art, the present invention effectively solves the problem of satisfying the clamping function through the rigidity of the reed in the traditional socket, and pushes the sliding mechanism to slide and Reset, so that the movable copper sheet on the sliding mechanism and the fixed copper sheet on the socket base are clamped or loosened. After repeated use, the clamping ability will not be affected, and the plug-in and pull-out is easy to ensure safety. .

detailed description

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

As shown in Figure 1, a mechanical elastic safety socket includes a socket upper seat and a socket base 1, the socket upper seat is connected with a push rod 4, and plug jacks 5 are arranged on both sides of the push rod 4, and on the push rod 4. The lower part is connected with a pawl 7; the socket base 1 is provided with a ratchet post 8 adapted to the pawl 7, and a sleeve 9 is slidably connected to the ratchet post 8, and sliding mechanisms are provided on both sides of the ratchet post 8.

The sliding mechanism is hinged to the sleeve 9 through the fork 12; the sliding mechanism includes a slide rail 10 and a slide block 11, the slide block 11 is hinged with one end of the fork 12, and the movable copper sheet 13 is fixedly connected on the slide block 11, and A fixed copper sheet 14 is installed on the socket base 1 . Both 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 socket 5 , and the opening of the guide groove is aligned between the movable copper sheet 13 and the fixed copper sheet 14 .

The socket upper seat includes a socket upper cover 2 and an end cover 3 , the socket upper cover 2 is matched with the socket base 1 , and the end cover 3 is snapped into the socket upper cover 2 . A movable chamber is arranged between the end cover 3 and the socket upper seat. A plurality of small return springs 6 are arranged in the movable chamber, and the two ends of the small return springs 6 respectively abut against the bottom of the end cover 3 and the upper seat of the socket. A large return spring is arranged between the sleeve 9 and the socket base 1 , and one end of the large return spring is 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, there is a protruding push rod 4 on the upper part of the socket. When the plug is inserted, the push rod 4 will be pushed downward, and the push rod 4 will push the pawl 7 to slide downward. 7 is rotated by radial force, and will be engaged with the ratchet wheel fixed on the socket to resist, because the downward movement of the ratchet 7 will drive the vertically sliding sleeve 9 under it, thereby compressing the spring and accumulating force. On the slidable sleeve 9, the fork 12 mechanisms with two equal arm lengths are hinged, and the other end of the fork 12 is hinged with the slide block 11 mechanism, so that the vertical sliding sleeve 9 moves down, driving the fork 12, and further Push the slider 11, the slider 11 moves outward along the slide rail 10, and at the same time drives the movable copper piece 13 on the slider 11 to move closer to the fixed copper piece 14 on the socket base 1, thereby realizing two copper pieces in the socket tension, forming a larger clamping force, and the plug socket 5 is aligned and pointed between the two copper sheets by the guide groove, and the copper sheet of the plug is firmly clamped by the two tensioned copper sheets in the socket, while At the same time, the guide groove avoids the problem of uneven force on the copper sheet of the plug, and the operation of the whole process is reliable.

When the push rod 4 is pressed down again, the ratchet mechanism engages again and returns to the previous position. Due to the stored force of the two return springs, the spring provides a restoring force and transmits the force to the push rod 4, thereby realizing "pop-up" . At this time, the slider 11 moves inwards under the action of the swing rod 12, and drives the movable copper piece 13 away from the fixed copper piece 14, effectively reducing the clamping force between the two copper pieces, so that the plug can be easily pulled out, and at the same time , Due to the distance between the two copper sheets, it can effectively avoid electric sparks when inserting the board, which is safer and effectively improves safety performance.

The above is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process conversion made by using the description of the invention and the contents of the accompanying drawings, or directly or indirectly used in other related technical fields , are all included in the scope of patent protection of the present invention in the same way.
