[0025] The following describes the specific embodiments of the present utility model in detail with reference to the accompanying drawings. It should be noted that the embodiments are only specific elaborations of the utility model and should not be regarded as limitations of the utility model. The purpose of the embodiments is to enable those skilled in the art to better understand and reproduce the technical solutions of the present utility model. The protection scope of the present utility model should still be subject to the scope defined by the claims.
[0026] As Figure 1 shown, the present utility model provides an anti-misoperation structure for a socket, including a protection piece 1, a reset device 2 and an automatic locking device 3. The automatic locking device 3 is configured to lock the misaligned protection piece 1, and the reset device 2 is configured to merge or open the protection piece 1 under the action of elastic force.
[0027] As Figures 2-6 shown, the protection piece 1 includes a door body portion 11 and a connecting portion 12. The connecting portion 12 is arranged on one side of one end of the door body portion 11. On the other side of one end of the door body portion 11, there is a placement portion 13, and the placement portion 13 is configured to place the connecting portion of another protection piece; a locking hole 121 is provided on the connecting portion 12.
[0028] In some preferred embodiments, a stop block 111 is provided on one side of the door body portion 11, and a first placement groove 1111 is provided in the stop block 111; a second placement groove 112 is provided at the other end of the door body portion 11.
[0029] The anti-misoperation structure includes two protection pieces. The connecting portion of one protection piece is arranged on one side of one end of the door body portion where the stop block 111 is provided, and the connecting portion of the other protection piece is arranged on one side of one end of the door body portion where the stop block 111 is not provided, so that the connecting portions of the two protection pieces are placed staggered front and back, which is convenient for the automatic locking device to lock. Preferably, the apertures of the locking holes 121 on the two protection pieces are inconsistent. The locking hole 121 of the connecting portion on the side where the stop block 111 is provided is smaller than the locking hole 121 of the connecting portion on the side where the stop block 111 is not provided, which is convenient for the fixing pin to penetrate into and withdraw from the locking holes of the two protection pieces.
[0030] Preferably, the connecting portion 12 is an arc surface, and when the protection piece 1 is in the open state, one end of the connecting portion 12 is also arranged at the position where the automatic locking device 3 locks. When there is a problem with the automatic locking device 3 and the fixing pin locks in advance, since there is no locking hole at one end of the connecting portion, the fixing pin cannot pass through the connecting portion and will not cause the situation that the protection piece cannot be reset.
[0031] In some preferred solutions, a placement area 113 is provided at one side end of the door body portion 11 of one protection piece, and a placement block 114 is provided at one side end of the door body portion of the other protection piece. The placement area 113 and the placement block 114 are arranged in a matching manner; when the two protection pieces are locked, the placement block 114 of the door body portion of one protection piece presses on the placement area 113 of the other door body portion, and the connecting portions of the two protection pieces are placed in a staggered manner and automatically locked by the automatic locking device 3, so that the two protection pieces 1 are closely attached to achieve a complete protection effect.
[0032] In some preferred solutions, the automatic locking device 3 includes a driving mechanism and a fixing pin 31, and the fixing pin 31 is configured to move along the direction in which the locking hole is provided under the action of the driving mechanism.
[0033] The driving mechanism includes a driving machine 321, a gear 322 and a rack 323. The gear 322 is connected to the driving shaft of the driving machine 321. The gear 322 is engaged with the rack 323. The rack 323 is connected to the fixing pin 31. When the driving machine 321 receives a signal to open the anti-touch device, it drives the gear 322 to drive the rack 323 and the fixing pin 31 to move in the opposite direction of the protection piece 1, so that the fixing pin 31 is removed from the locking hole 121. When the plug is pulled out, after the protection piece is reset under the action of the reset device, under the action of the driving machine 321, the gear 322 is driven to drive the rack 323 and the fixing pin 31 to move in the direction of the protection piece 1, and the fixing pin is placed in the locking hole 121 to achieve locking.
[0034] Or, the driving mechanism includes a driving machine, a worm gear and a worm. The driving shaft of the driving machine is connected to the worm gear. The worm gear is engaged with the worm. The worm is connected to the fixing pin. When the driving machine receives a signal to open the anti-touch device, it drives the worm gear to drive the worm and the fixing pin to move in the opposite direction of the protection piece, so that the fixing pin is removed from the locking hole. When the plug is pulled out, after the protection piece is reset under the action of the reset device, under the action of the driving machine, the worm gear is driven to drive the worm and the fixing pin to move in the direction of the protection piece, and the fixing pin is placed in the locking hole 121 to achieve locking.
[0035] In some preferred embodiments, the reset device 2 includes a torsion spring 21, a semi-circular gear 22, and a connecting shaft 23. The connecting shaft 23 is arranged in the shaft hole of the semi-circular gear 22. The torsion spring 21 is arranged on the connecting shaft 23 and drives the semi-circular gear 22 to rotate under the action of the torsion spring 21, thereby driving the protection piece 1 to open and close. Preferably, one end of the torsion spring 21 is arranged in the first placement groove 1111; the semi-circular gear 22 is arranged in the second placement groove 112.
[0036] Preferably, in order to protect the semi-circular gear 22, a baffle 4 is further arranged outside the semi-circular gear 22.
[0037] As Figure 7 shown, the present utility model provides a socket 5, and the socket includes the anti-misoperation structure 10 described above.
[0038] Although the preferred embodiments of the present application have been described, those skilled in the art can make additional changes and modifications to these embodiments once they know the basic creative concept. Therefore, the appended claims are intended to be construed as including the preferred embodiments and all changes and modifications falling within the scope of the present application.
[0039] It should be noted that the technical features not described in detail in the present utility model can all be realized by any prior art.
