When unlocking, in order to increase the driving force of the first swing piece to drive the first movable piece, on the basis of the extension of the force arm, the improvement of one of the following may not increase the stroke of the movable rod, thereby not increasing the product volume;

First, the other end of the first movable piece is provided with a first rotating shaft, and the bottom end of the first swinging piece is formed with a waist-shaped hole; in the locked state of the folded structure, the first rotating shaft is located at the waist shape a high position of the hole; in the folded state of the folded structure, the aforementioned first rotating shaft is located at a lower position of the waist hole.

Secondly, the bottom end of the first swinging piece is provided with a first rotating shaft, and the other end of the first movable piece is formed with a waist-shaped hole; in the locked state of the folded structure, the first rotating shaft is located at the waist shape The lower position of the hole; in the folded state of the folded structure, the aforementioned first rotating shaft is located at a high position of the waist hole.

The above waist hole can satisfy the first movable piece with sufficient moving distance.

In order to increase the connection strength of the support piece, the support piece includes a first support plate and a second support plate longitudinally disposed, and a connecting plate connected to the bottom of the first support plate and the bottom of the second support plate, the first support plate and The second support plates are arranged side by side, and the longitudinal cross section of the support sheets is U-shaped.

In order to improve the overall mechanical strength and the robustness of the support piece and the housing, the first support plate and the second support plate are provided with mounting holes, and the housing includes a first housing and a A casing is formed to cover the second casing, and the inner sides of the first casing and the second casing are respectively protruded with connecting posts adapted to the mounting holes.

Preferably, a middle portion of the housing is formed with a vertical strip-shaped cavity, and two ends of the movable rod respectively extend from the outer side surfaces of the first swinging piece and the second swinging piece and are vertically slidably disposed on the vertical direction In the strip cavity, a pull cord is connected to the movable rod, and the drawstring extends from the bottom of the housing out of the housing.

Further, a lower portion of the housing is provided with a card slot supported by the end portion of the positioning cable sleeve, and the lower end of the cable extends through the cable sleeve to extend outside the housing.

Preferably, the first swinging clip is two pieces and arranged side by side, the left guard bar is disposed between two first swinging clips, and the first movable piece is two pieces and juxtaposed Arranging, the first swinging piece is disposed between the two first movable pieces, and the first magnet can be engaged with at least one of the first movable pieces.

Preferably, the inner side wall of the casing is provided with a supporting top plate, the side surface of the supporting top plate is formed with an inner groove, and the first magnet is disposed on the inner groove and exposed to the first movable piece Abutting the bottom of the part.

Preferably, the first swinging piece is movably connected to the right end of the first movable piece at a bottom end of the left side, specifically The structure is: the right end of the first movable piece is connected with the bottom end of the first swing piece through the first rotating shaft; the second swing piece is located at the bottom end of the right side and is movably connected with the left end of the second movable piece, the specific structure The left end of the second movable piece and the bottom end of the second swing piece are connected by the second rotating shaft.

Preferably, the support piece is two pieces and is symmetrically fixed in the front and rear, and the first magnet is embedded in the first card cavity of the two support pieces or one of the support pieces, and the second magnet is embedded. In the second card cavity of the two supporting pieces or one of the supporting pieces.

Compared with the prior art, the folding device of the present invention realizes the resetting and locking of the folding device by providing a pair of magnets respectively to the right end of the first movable piece and the left end of the second movable piece, and the left and right protective bars are gradually pulled by the external force. When opened, the magnet can adsorb the movable piece to speed up the resetting speed and reduce the force of resetting. When the left and right protective bars are fully deployed, the magnet can continuously adsorb the movable piece to prevent the movable piece from moving again, thereby locking the protective rod to improve the folding device. The role of stability;

In addition, the folding device adopts a swinging piece designed by a "human" shape. When the pulling rope pulls the movable rod, the movable rod moves downward to keep the unfolded left and right protective rods folded synchronously, and when the pulling rope loses external force, the left and right protective rods Under the action of the magnet adsorption force and the auxiliary hand pulling force, it can maintain synchronous extension, which is very stable. More importantly, after the magnet is locked and locked, the action is quick when unlocking, that is, there is no resistance when it is unlocked, so it can be unlocked instantaneously;

In addition, when the left and right guard bars are fully deployed, since the axis of the hinge shaft is located on the line connecting the axis of the lever shaft and the axis of the movable shaft or below the line, this ensures that when the left and right guard bars are extended, Can automatically lock, that is, the left and right guards can not move downwards, because the hinge shaft passes the dead point or three points on a line position, and the other end of the swing piece is supported by the through shaft and the recess of the housing, so that the hinge The shaft can't move downwards and achieve the purpose of automatic locking. When unlocking, the pulling rod pulls the movable rod to move the movable rod downwards. The movable rod has the swinging piece and the movable piece to get rid of the magnet adsorption and then drive the hinge shaft, so that the hinge shaft passes dead. Point, that is, the purpose of automatic unlocking;

Moreover, when the left and right guard bars are unfolded and folded, they do not interfere with each other, which not only reduces the pulling force of the drawstring, but also prolongs the service life of the drawstring, and makes the stack mechanism more flexible and labor-saving, and adopts a lever type structure, and the space occupied by the components is smaller. , using less material and lower production costs, so the structure is more reasonable;

As another aspect of the present invention, when the folding device of the present invention is lifted up, since the pivot point of the first hinge shaft is close to the axis of the first movable shaft and the axis of the first lever shaft, Providing a tendency for the first hinge to move downward in the axial direction, thereby completely overcoming the friction between the components, so that the right end of the first movable piece and the first magnet are upturned, and the first movable piece and the first magnet are attracted to each other. Live and get positioned, the second movable piece also performs similar actions at the same time. When it is put down, the entire folding structure is completely locked, thus eliminating false locks and avoiding safety accidents caused by false locks.
