Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-3, a power adapter convenient to pull out and insert, including shell 1 and the inserted hole 2 that is located the shell 1 surface, the inside sliding connection of inserted hole 2 has plug 11, two centre gripping grooves 3 have been seted up on the surface of shell 1, two centre gripping grooves 3 are located the both sides of inserted hole 2 respectively, the inside sliding connection of centre gripping groove 3 has supporting rod 4, supporting rod 4 passes through

compression spring

5 and 3 elastic connection in centre gripping groove, the one end that supporting rod 4 kept away from centre gripping groove 3 is equipped with the restriction piece 6 that is the U-shaped, specifically, restriction piece 6 and supporting rod 4 sliding connection, spout 7 has been seted up to the bottom of restriction piece 6, the one end of supporting rod 4 is located inside spout 7, be equipped with fixed establishment 8 between two restriction pieces 6, specifically, fixed establishment 8 makes detachable fixed connection between two restriction pieces 6.

The scheme has the following working processes:

when the power adapter is needed to be used, the two limiting blocks 6 slide away from each other through the sliding groove 7, the plug 11 is inserted into the insertion hole 2, the clamping rod 4 is pulled, the clamping rod 4 rises to leave the clamping groove 3, the two limiting blocks 6 slide close to each other, a gap between the two limiting blocks 6 can be penetrated by a power line of the plug 11, the two limiting blocks 6 can be detachably and fixedly connected through the fixing mechanism 8, the limiting blocks 6 are close to the shell 1 through the compression spring 5, and the plug 11 is extruded and fixed.

According to the working process, the following steps are known:

through the restriction to the plug 11, the plug 11 can be inserted into the insertion opening 2 even if loosened, so that the plug 11 cannot be in poor contact, and the plug 11 can be conveniently pulled out, and the plug 11 cannot be pulled out difficultly due to friction force.

Further, fixing mechanism 8 includes two fixed covers 801 of respectively fixed connection in one of them restriction piece 6 both sides, the equal fixed connection inserted bar 802 in both sides of another restriction piece 6, inserted bar 802 wears to locate inside adjacent fixed cover 801, fixed slot 803 has been seted up to one side of inserted bar 802, the inside sliding connection of fixed slot 803 has fixed block 804, fixed block 804 passes through extrusion spring 805 and fixed slot 803 elastic connection, specifically, inserted bar 802 is after inserting fixed cover 801, fixed block 804 pops out fixed slot 803 through extrusion spring 805, then fixed block 804 prevents that inserted bar 802 from leaving fixed cover 801, make two restriction piece 6 fixed connection, when extracting plug 11, extrude fixed block 804 and get into fixed slot 803, make fixed block 804 not blockking that inserted bar 802 leaves fixed cover 801.

Further, the cross section of the fixing groove 803 is T-shaped, and the cross section of the end of the fixing block 804 located inside the fixing groove 803 is T-shaped, specifically, the fixing block 804 is prevented from completely separating from the fixing groove 803.

Further, the clamping rod 4 is located the inside one end fixedly connected with slider 9 of spout 7, and the cross-section of spout 7 is the T shape, and is concrete, and slider 9 can not break away from spout 7 to slider 9 makes clamping rod 4 can be better with spout 7 sliding connection.

Further, the top fixedly connected with of restriction piece 6 is the pull rod 10 of the shape of falling U, and is concrete, and pull rod 10 conveniently pulls out centre gripping groove 3 with supporting rod 4 through restriction piece 6 for the insertion of plug 11 is more convenient.

Further, the height of centre gripping groove 3 is less than the height of clamping rod 4, and is concrete for clamping rod 4 can not enter into centre gripping groove 3 completely, makes restriction piece 6 can not contact with shell 1, protects restriction piece 6.

In summary, the restriction block 6 allows the plug 11 to be restricted after being inserted into the insertion port 2, and the fixing mechanism 8 can prevent poor contact caused by movement of the plug 11 after insertion, and also facilitate removal of the plug 11.
