Detailed Description

Referring to fig. 1, 2, 3, 4 and 5, the anti-pinch self-locking device of the magnetic adjusting glass wiper of the present invention comprises an upper top cover 1, an upper bottom cover 11 and an upper magnet group 12 of an inner wiper, a lower top cover 2, a lower bottom cover 21 and a lower magnet group 22 of an outer wiper, and a push key body 3, a push key body return spring 31, a top column 4, a top column positioning seat 41 and a top column return spring 45 on the inner wiper; a top post hole 42; the two top columns are in a group, and the tops of the two top columns are connected into a whole to form a conjoined body 44; the top column 4 is movably matched with the top column hole 42; the bottom of the lower end of the push key body 3 is provided with a key body locking block 5 protruding downwards, and the top conjuncted body 44 of the top post 4 is provided with a concave top post locking groove 6 corresponding to the key body locking block 5; when the inner wiping body and the outer wiping body are sucked, the key body locking block 5 is embedded into the top column locking groove 6 and is in a self-locking state, as shown in fig. 1, the top column 4 extends out of the bottom of the upper bottom cover 11 to prop against the lower bottom cover 21, and the limiting surface 441 at the bottom end of the conjuncted body 44 is higher than the upper edge of the top column hole 42 by an unlocking height, so that the top column 4 is kept with a downward movement amount, and the unlocking height is higher than the depth of the key body locking block 5 embedded into the top column locking groove 6, so that when the top column 4 and the conjuncted body 44 move downwards together by an unlocking height, the key body locking block 5 can be separated from the top column locking groove 6 to be unlocked; the bottom of the top column 4 extends out of the upper bottom cover 11 by a certain length, so that an anti-pinch distance is kept between the lower bottom cover 21 and the upper bottom cover 11.

Referring to fig. 3 and 6, the top pillar 4 is nested outside the top pillar positioning seat 41 in a sliding fit manner, and the top pillar return spring is installed on the guide pillar 43 in the spring hole of the top pillar positioning seat 41 and the top pillar 4; the top post positioning seats 41 are fixed in the upper top cover 1, one top post positioning seat is arranged on each of the two longitudinal sides of the push key body 3, and two top post groups 44 of the top posts are longitudinally matched and connected with the top post positioning seats 41; the push key bodies 3 are respectively and symmetrically arranged in a pair in the transverse left-right direction, the top posts are respectively and symmetrically arranged in a group in the transverse left-right direction, and the top post locking grooves 6 are arranged in the middle of the conjoined body 44.

The push key body 3 horizontally slides in the push key groove 46 of the upper top cover 1 and is reset by the push key body return spring 31 horizontally sleeved on the push key body 3, as shown in fig. 6.

The key body locking piece 5 can also be replaced by a key body locking groove, and the corresponding top column locking groove 6 can also be replaced by a corresponding top column locking piece.

The utility model discloses a theory of operation:

when the inner wiping body and the outer wiping body are separately sucked and stored, the key body locking block 5 is embedded into the top column locking groove 6 and is in a self-locking state, as shown in fig. 1, due to the fact that the inner wiping body and the outer wiping body are sucked, the bottom of the top column 4 abuts against the lower bottom cover 21, the bottom limiting surface 441 of the conjoined 44 is higher than the upper edge of the top column hole 42 by an unlocking height, the unlocking height is higher than the depth of the key body locking block 5 embedded into the top column locking groove 6, and the bottom of the top column 4 extends out of the upper bottom cover 11 by a length, so that an anti-pinch distance is kept between the lower bottom cover 21 and the upper bottom cover 11.

When the inner eraser and the outer eraser are separated, as shown in fig. 2 and 3, the top post 4 further moves downwards by an unlocking height under the action of the top post return spring 45 to eject the upper bottom cover 11 until the limiting surface 441 at the bottom end of the conjuncted body 44 abuts against the upper edge of the top post hole 42, and because the limiting surface 441 at the bottom end of the conjuncted body 44 is designed to be self-locked and is higher than the inner side surface of the upper bottom cover 11 by an unlocking height, the conjuncted body 44 is lowered by an unlocking height, so that the top post locking groove 6 of the top post 4 is lowered by an unlocking height, so that the top post locking groove 6 is separated from the locking block 5 to realize unlocking, and at this time, the push key bodies 3 at two sides are pushed to compress the push key body return springs 31 to move towards the middle, the top post 4 can freely stretch and retract, and can be attached to the glass to attract and wipe the glass with the outer eraser outside the window.
