The embodiments described below with reference to the drawings are intended to be illustrative of the invention and are not to be construed as limiting.

As shown in FIG. 1 to FIG. 5, an embodiment of the present invention provides a socket for a blind person, comprising: a base 1 having a receiving cavity 2, the receiving cavity 2 being on one side of the base 1 An opening 3 is provided; the base 1 can be embedded in the wall body, and the opening 3 faces outward; the socket body 4 is slidably disposed in the accommodating cavity 2, and the socket body 4 is provided with a socket, wherein the wire is connected Referring to the prior art, no description is made herein; a driving member is connected to the socket body 4 to drive the socket body 4 to move toward or away from the opening 3; the shutter includes a left baffle 5 and a right baffle 6. The surface of the base 1 is recessed with a sliding slot 7 on both sides of the opening of the opening 3. One end of the sliding slot 7 communicates with the opening 3, the left flap 5 and the right The baffles 6 are slidably disposed in the chute 7 respectively.

In the initial state, the left baffle 5 and the right baffle 6 block the opening 3, and the socket main body 4 is away from the opening 3, so that the blind finger is not inserted into the jack. When in use, the plug first contacts the baffle, and the plug will be left. The baffle 5 and the right baffle 6 are extended to the bottom of the chute 7, and the opening 3 is opened. At this time, the driving member drives the socket main body 4 to be close to the opening 3, and the plug can be inserted into the jack of the socket main body 4 to supply power and pull out the plug. When the baffle and the socket body 4 are returned.

In this embodiment, the driving of the socket body 4 is realized by using a purely mechanical logic cooperation manner, which is safe and reliable. Specifically, the base 1 is provided with a concave working cavity 8 , and the inner side of the concave working cavity 8 is The three sides of the accommodating chamber 2 are in communication with the concave working chamber 8. The driving member is provided with two sets, symmetrically disposed in the concave working chamber 8, and the left baffle 5 and the right baffle 6 each have a driving member, and the bottom of the chute 7 is also in communication with the concave working chamber 8. The driving member includes a first rotating shaft 9, a second rotating shaft 10 and a third rotating shaft 11 which are rotatably mounted. The manner of the rotary mounting refers to the matching manner of the bearing housing in the prior art, and is not described herein. Here, the axial direction of the first rotating shaft 9 is defined as the X direction, and the axial direction of the second rotating shaft 10 is the Y direction. The axial direction of the third rotating shaft 11 is a Z-direction. The first rotating shaft 9 is sleeved with a driving gear 12 and a worm wheel 13. The bottom of the socket body 4 is provided with a rack 14, the driving gear 12 and the tooth. The strips 14 are engaged, and the axis of the second rotating shaft 10 is perpendicular to the axis of the first rotating shaft 9, One end of the two rotating shaft 10 is provided with a worm segment 15 meshing with the worm wheel 13, and the other end of the second rotating shaft 10 is sleeved with a first bevel gear 16, the axis of the third rotating shaft 11 and the second The axis of the rotating shaft 10 is perpendicular, one end of the third rotating shaft 11 is fixed with a second bevel gear 17, and the second bevel gear 17 is meshed with the first bevel gear 16, and the third rotating shaft 11 The other end is fixed with a rocker arm 18, and a roller 19 is fixed to an end of the rocker arm 18 facing away from the third rotating shaft 11; a guiding groove 20 is recessed on the back of the left baffle plate 5 and the right baffle plate 6; The guiding groove 20 extends laterally and includes a first guiding section 21, a connecting section 22 and a second guiding section 23, wherein the height of the second guiding section 23 is higher than the height of the first guiding section 21, the connecting section The two ends of the 22 are respectively connected to the first guiding section 21 and the second guiding section 23, and the roller 19 extends into the guiding groove 20.

Normally, the left baffle 5 and the right baffle 6 are in contact with each other, the roller 19 is in the first guiding section 21, and the left baffle 5 and the right baffle 6 are far apart from each other when the plug is inserted. During this process, the roller 19 is raised from the first guiding section 21 to the second guiding section 23, and when the roller 19 is rolled from the end of the connecting section 22 to the second guiding section 23, the left flap 5 and the right flap 6 are just right. Moving to the extreme end, the rotation of the rocker arm 18 is transmitted to the rack 14 via the third rotating shaft 11, the second rotating shaft 10 and the first rotating shaft 9, and the socket body 4 is slid to the opening 3, so that the plug can be inserted. In the hole, when the power supply is finished, when the plug is pulled out, the baffle is returned, the roller 19 is returned to the first guiding section 21 by the second guiding section 23, the rocker arm 18 is reversed, and the rack 14 is driven to move in the reverse direction, and the socket body 4 is thereby Keep away from the opening 3. The socket body 4 is obtained by means of pure physical logic, which is convenient and reliable, and saves cost.

In order to enable the left baffle 5 and the right baffle 6 to be smoothly returned, a spring 24 is fitted between the left baffle 5 and the right baffle 6 and the bottom of the chute 7. When the left flap 5 and the right flap 6 are apart from each other, the spring 24 is compressed to accumulate elastic force, and when the plug is pulled out, the flap is returned by the elastic force of the spring 24.

In order to enable the plug to be smoothly inserted at the time of insertion and to reduce the resistance, the outer surfaces of the left flap 5 and the right flap 6 are provided with guide slopes 25. The plunger of the plug first contacts the guide ramp 25 to separate the left flap 5 and the right flap 6 from each other.

In order to limit the depth of penetration of the plug, the receiving cavity 2 is formed with a stepped surface 26 on both sides of the opening 3. After the plug is inserted into the bottom, the body of the plug abuts against the stepped surface 26 for limiting.

As a preferred technical solution of the present embodiment, the bottom of the socket body 4 is provided with a slider 27, and a bottom portion of the concave working chamber 8 is fixed with a guide rail 28 that is slidably engaged with the slider 27. The slider 27 can be provided with a pair of symmetrical settings to enhance the sliding effect.

The embodiments, features and effects of the present invention are described in detail above with reference to the embodiments shown in the drawings. The above description is only a preferred embodiment of the present invention, but the present invention is not limited by the scope of the drawings, and It is intended that the present invention be construed as being limited by the scope of the invention.
