[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1 to 3 ,as well as Figure 10 As shown, a guardrail frame includes two support frames 1 spaced apart on the left and right sides, the support frames 1 being connected to a main frame 2 that can be raised and lowered relative to the support frames 1, the lower ends of the support frames 1 being connected to a U-shaped bottom frame 3 that can be rotated and folded relative to the support frames and can be pressed by a mattress 100 in the unfolded state, the open ends of the U-shaped bottom frames 3 being connected to the lower ends of the corresponding support frames 1, the main frames 2 being provided with side frames 4 on both sides that can be rotated and unfolded or folded relative to the main frame 2, the positions in which the side frames 4 can stay include a folded position stacked with the main frame 2, an unfolded position extending toward the side of the main frame 2, and a vertical position extending toward one side of the U-shaped bottom frame 3 and perpendicular to the main frame 2, a locking device 5 being provided between the side frames 4 and the main frame 2 that can keep the side frames 4 in the folded position, unfolded position or vertical position. When the guardrail frame is fitted with a cloth cover and used, the U-shaped bottom frame 3 is first rotated and unfolded, and the U-shaped bottom frame 3 can be pressed by the mattress 100, so that the guardrail is installed to the side of the bed, and the side frames 4 can be unfolded to the unfolded position relative to the main frame 2 (such as Figure 2 ), at this time, the side frame 4 extends the length of the main frame 2 to both sides, so that the protection range is larger, and the infant will not fall from the side of the bed to the ground when playing on the bed. When the infant sleeps at night, the side frame 4 can be adjusted to a vertical position perpendicular to the main frame 2 (such as Figure 1), at this time, the guardrail can protect the infant from three directions, and the infant sleeps in the space enclosed by the side frame 4 and the main frame 2, preventing the infant from unconsciously shifting during sleep and avoiding the risk of being crushed by adults after shifting, thereby ensuring safety; and when the user travels, the side frame 4 can be rotated relative to the main frame 2 to the folding position (such as Figure 3 ), the U-shaped bottom frame 3 is also rotated and moved closer to the main frame 2, so that it can be placed in a suitcase and carried around. After arriving at the hotel, it can be unfolded and used, which is very convenient and quick.

[0031] like Figure 1 、 Figure 2 and Figure 10 As shown, the guardrail frame also includes a flexible drawstring 6. One end of the drawstring 6 is connected to the U-shaped bottom frame 3. The other end of the drawstring 6 is connected to an L-shaped hooking piece 7 that can hook onto the side wall of the mattress 100. When the guardrail is installed on the bed, the drawstring 6 is pressed against the mattress 100 and extends to the other side of the mattress 100. The L-shaped hooking piece 7 can hook onto the side wall of the mattress 100, thereby preventing the U-shaped bottom frame 3 from falling out from under the mattress and ensuring greater safety. The drawstring 6 can be an elastic band.

[0032] like Figure 4 and Figure 5 As shown, the U-shaped bottom frame 3 includes a U-shaped tube 31, the support frame 1 includes a vertical support rod 11 that is slidably connected to the main frame 2, and an L-shaped connecting seat 12 is provided at the lower end of the support rod 11. The L-shaped connecting seat 12 includes a vertical seat 121 connected to the support rod 11 and a horizontal seat 122 protruding to one side of the vertical seat 121. A locking assembly for locking the two is provided between the U-shaped tube 31 and the horizontal seat 122, and the locking assembly includes a slot 81 provided on the horizontal seat 122. The end of the U-shaped tube 31 is provided with a There is a card joint 82 that can engage with or disengage from the card slot 81, and a connecting shaft 83 is provided on the transverse seat 122. The card joint 82 is provided with a strip hole 84 for the connecting shaft 83 to pass through and can make way for the connecting shaft 83 when the card joint 82 is disengaged from the card slot 81. The lower side of the transverse seat 122 is also provided with a makeshift groove 85 that can make way for the rotating U-shaped tube 31 when the card joint 82 slides relative to the transverse seat 122 and disengages from the card slot 81. A first return spring 86 is also provided between the connecting shaft 83 and the card joint 82 to push the card joint 82 to return to its original position. When the U-shaped bottom frame 3 is relatively locked with the support frame 1, the card joint 82 is stuck in the card groove 81, and the U-shaped bottom frame 3 cannot be rotated and folded. When folding is required, the U-shaped tube 31 is pulled outward. Due to the presence of the strip hole 84, the U-shaped bottom frame 3 can slide relative to the transverse seat 122, and the card joint 82 is disengaged from the card groove 81. At this time, the U-shaped bottom frame 3 can be rotated around the connecting shaft 83, and the open end of the U-shaped bottom frame 3 passes through the makeshift groove 85, so that the U-shaped bottom frame 3 is erected and folded close to the main frame 2.

[0033] like Figures 3 to 5 As shown, the upper side of the transverse seat 122 is further provided with an opening slot 87 that communicates with the clearance slot 85 and allows the U-shaped tube 31 to enter when the U-shaped bottom frame 3 is rotated and folded relative to the transverse seat 122, so that the U-shaped bottom frame 3 is parallel to the main frame 2. When the U-shaped bottom frame 3 is rotated and folded, the U-shaped tube 31 can enter the opening slot 87, so that the U-shaped bottom frame 3 can be upright and parallel to the main frame 2, making the guardrail frame small in size after folding and easy to carry.

[0034] like Figure 5 As shown, the end of the clamping joint 82 is provided with an inclined surface 88 that can be pushed against the junction of the clearance groove 85 and the clamping groove 81 when the U-shaped bottom frame 3 is rotated and unfolded relative to the transverse seat 122. When the guardrail frame is unfolded, the U-shaped bottom frame 3 rotates around the connecting shaft 83, and the inclined surface 88 is pushed against the junction of the clearance groove 85 and the clamping groove 81. The U-shaped bottom frame 3 slides relative to the transverse seat 122, and the first return spring 86 is compressed. Once the U-shaped bottom frame 3 rotates until the clamping joint 82 is aligned with the clamping groove 81, the first return spring 86 pushes the clamping joint 82 to engage with the clamping groove 81, thereby achieving locking.

[0035] like Figure 1 and Figure 2 As shown, the main frame 2 includes two vertical tubes 21 sleeved on the support rod 11, and an upper cross bar 22 and a lower cross bar 23 connecting the two vertical tubes 21 are provided between the two vertical tubes 21. The end of the upper cross bar 22 is provided with an upper connecting seat 24, and the end of the lower cross bar 23 is provided with a lower connecting seat 25. The side frame 4 includes a U-shaped rod 41, and the upper end of the U-shaped rod 41 is provided with an upper connecting head 42 rotatably connected to the upper connecting seat 24, and the lower end of the U-shaped rod 41 is provided with a lower connecting head 43 rotatably connected to the lower connecting seat 25. When the side frame 4 is connected to the main frame 2, the vertical tube 21 closes the open end of the U-shaped rod 41, and the locking device 5 is provided between the upper connecting head 42 and the upper connecting seat 24.

[0036] like Figure 6 、 Figure 8 and Figure 9As shown, the locking device 5 includes four first locking grooves 51 arrayed in a circumferential direction on the upper connecting seat 24, and four second locking grooves 52 arrayed in a circumferential direction on the upper connecting head 42. A spline 53 that can move therein and engage with the first locking groove 51 and the second locking groove 52 is provided in the space enclosed by the upper connecting head 42 and the upper connecting seat 24. The spline 53 includes a main body 531, and the main body 531 is provided with a protruding locking block 532 that can engage with the first locking groove 51 and the second locking groove 52. The upper connecting seat 24 is provided with an exposed pressing piece 54 that can push the spline 53 to disengage from the first locking groove 51 after being pressed. A second return spring 55 that can push the spline 53 to return to its original position is provided between the upper connecting head 42 and the spline 53. By pressing the pressing member 54, the spline 63 is disengaged from the first locking groove 51, allowing the side frame 4 to be rotated relative to the main frame 2. When the side frame 4 reaches the vertical position or the folded position, the second return spring 55 pushes the spline 53 back to its original position, whereupon the spline 53 simultaneously engages with the first locking groove 51 and the second locking groove 52, achieving locking. Since there are four first locking grooves 51 and second locking grooves 52, and four locking blocks 532 on the spline 53, the side frame 4 can remain in the vertical position perpendicular to the main frame 2 or in the folded position stacked with the main frame 2 after rotation.

[0037] like Figure 9 As shown, the upper connecting seat 24 has two through holes 56 arranged in a circumferential direction, and the pressing member 54 includes a pressing portion 541. The pressing portion 541 is provided with a push column 542 that passes through the through hole 56 and abuts against the spline 53. The pushing column 542 is provided with a hook portion 543 that protrudes to one side and can hook the inner edge of the through hole 56. The hook portion 543 prevents the pressing member 54 from falling off from the upper connecting seat 24.

[0038] like Figures 5 to 7As shown, a locking assembly that can lock the relative positions of the two is provided between the vertical tube 21 and the support rod 11, and the locking assembly includes a plurality of locking holes 91 provided on the support rod 11 along the vertical direction, and a connecting hole (not shown in the figure) is provided on the vertical tube 21, and the lower connecting seat 25 includes a seat body 251 fixedly connected to the lower cross bar 23, and the seat body 251 is fixedly connected to the lower end of the vertical tube 21, and the seat body 251 is provided with a connecting portion 252 that is integrally formed with it and rotatably connected to the lower connecting head 43, and a card block 93 that passes through the connecting hole and can be engaged or disengaged with the locking hole 91 is slidably connected in the seat body 251, and a toggle button 94 exposed on the seat body 251 is fixedly connected to the card block 93, and a third return spring 95 that can push the toggle button 94 to return to its original position is also provided between the toggle button 94 and the seat body 251. When the toggle button 94 is pushed, the block 93 can be withdrawn from the locking hole 91. At this time, the height of the main frame 2 can be adjusted up and down. Therefore, it can be ensured that for mattresses of different thicknesses, the lower cross bar 23 can also be adjusted to a position close to the upper surface of the mattress, so that the guardrail can adapt to mattresses of different thicknesses.

[0039] The embodiment is described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiment. Various changes can be made within the knowledge of ordinary technicians in the technical field without departing from the present invention.
