[0025] The utility model is further described below in conjunction with the accompanying drawings:

[0026] like Figures 1 to 8As shown, a foldable guardrail comprises a left vertical rod 1 and a right vertical rod 2, and an upper crossbar 13 and a lower crossbar 14 connecting the left vertical rod 11 and the right vertical rod 12, wherein the left vertical rod 11, the right vertical rod 12, the upper crossbar 13 and the lower crossbar 14 form a guardrail body 1, the left side of the left vertical rod 11 is provided with a left U-shaped frame 2 which can be rotated and unfolded or rotated and folded relative to the guardrail body 1, the right side of the right vertical rod 12 is provided with a right U-shaped frame 3 which can be rotated and unfolded or rotated and folded relative to the guardrail body 1, the lower end of the guardrail body 1 is connected to a support assembly 4 which can be telescopic relative thereto, the support assembly 4 comprises a left sliding rod 41 which can telescopically slide in the left vertical rod 11 and a right sliding rod 42 which can telescopically slide in the right vertical rod 12, the left sliding rod 41 and the right sliding rod 42 The lower end of the movable rod 42 is provided with an L-shaped connecting seat 43, and the connecting seat 43 includes a vertical section 431 and a horizontal section 432, wherein the vertical section 431 of one connecting seat 43 is connected to the left sliding rod 41, and the vertical section 431 of the other connecting seat 43 is connected to the right sliding rod 42, and the horizontal section 432 is provided with a U-shaped support frame 44 which can be pressed by the mattress together with the horizontal section 432 and can be folded toward the guardrail body 1 after rotating relative to the horizontal section 432, and a first locking mechanism 45 which can lock the two is provided between the support frame 44 and the horizontal section 432, and a second locking mechanism 6 which can lock the two is provided between the support assembly 4 and the guardrail body 1, and a third locking mechanism 7 is provided between the left U-shaped frame 2 and the right U-shaped frame 3 and the guardrail body 1. When in use, the user can cover the left U-shaped frame 2 and the right U-shaped frame 3 with a flexible cloth cover to achieve a better blocking effect. During installation, the user first rotates and opens the support frame 44, inserts the support frame 44 under the mattress and is pressed by the mattress, and then rotates and opens the left U-shaped frame 2 and the right U-shaped frame 3 to both sides. The installation operation is very convenient and quick. During folding, the user only needs to unlock the third locking mechanism 7 to rotate the left U-shaped frame 2 and the right U-shaped frame 3 to move closer to the guardrail body 1, and then takes the support frame 44 out from under the mattress, unlocks the first locking mechanism 45, and rotates the support frame 44 to move closer to the guardrail body 1, thereby realizing the folding of the entire guardrail. The folding operation is also very convenient, and the folded volume is small and can be carried in a suitcase. In addition, the height of the guardrail body 1, the left U-shaped frame 2 and the right U-shaped frame 3 can be adjusted after unlocking the second locking mechanism 6 to adapt to specific application occasions.

[0027] like Figures 3 to 5 and Figure 7As shown, the first locking mechanism 45 includes a locking sleeve 451 which is arranged on the support frame 44 and can slide relative to the support frame 44, the transverse section 432 is provided with an open groove 452 with upper and lower openings, the support frame 44 and the locking sleeve 451 are inserted into the open groove 452 and are rotatably connected to the transverse section 432 through a pin shaft 453 arranged on the transverse section 432, the locking sleeve 451 is provided with a strip groove 454 which can make way for the pin shaft 453 when it slides relative to the support frame 44, the groove wall of the opening groove 452 is provided with a snap-fitting groove 458, and the outer side wall of the locking sleeve 451 is provided with a snap-fitting block 459 which can engage with or disengage from the snap-fitting groove 458 when it slides relative to the support frame 44. A first reset spring 457 which can push the locking sleeve 451 to slide and reset is provided between the pin shaft 453 and the locking sleeve 451. When the foldable guardrail is in the unfolded state, the engaging block 459 on the locking sleeve 451 is engaged in the engaging groove 458 on the connecting seat 432, so that the support frame 44 is securely locked with the connecting seat 432. When it is necessary to fold, the locking sleeve 451 is slid relative to the support frame 44, and the engaging block 459 on the locking sleeve 451 is withdrawn from the engaging groove 458. At this time, the first return spring 457 is compressed, and the support frame 44 and the locking sleeve 451 can be rotated relative to the transverse section 432, so that the support frame 44 can be close to the guardrail body 1, ensuring that the guardrail has a small volume and is compact after folding. When the support frame 44 needs to be unfolded, the support frame 44 is rotated. During the rotation, the locking block 459 on the locking sleeve 451 touches the edge of the opening groove 452, and the edge of the opening groove 452 pushes the locking sleeve 451 to slide and compresses the first return spring 457. The support frame 44 and the locking sleeve 451 continue to be rotated until the locking block 459 is aligned with the locking groove 458, and the first return spring 457 pushes the locking sleeve 451 to slide and return to its original position. At this time, the locking block 459 on the locking sleeve 451 is locked with the locking groove 458 on the connecting seat 43 again.

[0028] like Figure 7 As shown, the locking sleeve 451 is provided with a transverse axis 451a, and the support frame 44 is provided with a strip hole 44a for the transverse axis 451a to pass through and can make way for the transverse axis 451a when the locking sleeve 451 slides relative to the support frame 44, and the cooperation between the strip hole 44a and the transverse axis 451a can play a guiding role.

[0029] like Figure 7As shown, the end of the locking sleeve 451 is provided with a stop 455, and the connecting seat 43 is provided with a protrusion 456 that can abut against the stop 455. When the support frame needs to be unfolded, the support frame 44 is rotated, and the edge of the opening groove 452 pushes the locking sleeve 451 to slide, so that the first return spring 457 is compressed. During the process of continuing to rotate the support frame 44 and the locking sleeve 451, the stop 455 on the locking sleeve 451 abuts against the protrusion 456 on the connecting seat 43, and the support frame 44 cannot be rotated further, which indicates that the support frame 44 has been rotated to a proper position. The cooperation between the stop 455 and the protrusion 456 plays a role of limiting and prompting. At this time, the first return spring 457 also pushes the locking sleeve 451 to slide and reset, and the locking block 459 on the locking sleeve 451 is locked with the locking groove 458 on the connecting seat 43 again. Therefore, when the support frame 44 is unfolded, it is only necessary to directly rotate the support frame 44, so that the unfolding operation of the guardrail is convenient.

[0030] like Figure 7 As shown, the said locking position 455 is a notch provided at the end of the locking sleeve 451, and when the support frame 44 is in the unfolded state, the said notch abuts against the protrusion 456. Therefore, when the notch abuts against the protrusion 456, it can limit the further rotation of the support frame 44 and the locking sleeve 451 in one direction relative to the connecting seat 43, and play a role of limiting and prompting. When the locking block 459 is disengaged from the locking groove 458, when the rotating support frame 44 and the locking sleeve 451 are folded, the notch and the protrusion 456 can be quickly disengaged.

[0031] like Figure 1 , Figure 2 and Figure 4As shown, the second locking mechanism 6 includes a plurality of adjustment holes 61 arranged on the left sliding rod 41 and the right sliding rod 42 along the vertical direction, and locking sleeves 15 are provided at both ends of the lower cross bar 14. The locking sleeves 15 include a connecting sleeve 151 that can be connected to the left vertical rod 11 and the right vertical rod 12 and is sleeved on the left sliding rod 41 and the right sliding rod 42. The connecting sleeve 151 is provided with a transverse tube 152 connected to the end of the lower cross bar 14, and a locking block 62 that can slide therein and can engage or disengage with the adjustment hole 61 is provided in the transverse tube 152. The locking block 62 is provided with a toggle button 63 with the transverse tube 152 exposed, and the transverse tube 152 is also provided with a second reset spring 64 that can push the locking block 62 to move and reset. The left vertical rod 11 can slide relative to the left sliding rod 41, and the right vertical rod 12 can slide relative to the right sliding rod 42. Therefore, the heights of the guardrail body 1, the left U-shaped frame 2 and the right U-shaped frame 3 can be adjusted to meet the needs of users. For example, the height can be adjusted when encountering mattresses of different thicknesses. When the mattress is thicker, it can be adjusted higher, and when the mattress is thinner, it can be adjusted lower. When adjusting the height, it is only necessary to push the toggle button 63 to disengage the locking block 62 from the corresponding adjustment hole 61. The operation is very convenient and quick. When adjusted to the appropriate position, the second return spring 64 pushes the locking block 62 to engage with the corresponding adjustment hole 61.

[0032] like Figure 1 and Figure 6 As shown, the third locking mechanism 7 includes a first locking seat 71 provided at the open ends of the left U-shaped frame 2 and the right U-shaped frame 3, a second locking seat 72 capable of rotating relative to the first locking seat 71 is provided on the guardrail body 1, a plurality of first teeth 73 are provided on the first locking seat 71 along the circumferential direction, and a plurality of second teeth 74 capable of meshing with the first teeth 73 are provided on the second locking seat 72. When the first teeth 73 mesh with the second teeth 74, the left U-shaped frame 2 and the right U-shaped frame 3 stay in the unfolded or folded position, and when the left U-shaped frame 2 or the right U-shaped frame 3 is rotated relative to the guardrail body 1, the first teeth 73 are disengaged from the corresponding second teeth 74. Therefore, when the left U-shaped frame 2 and the right U-shaped frame 3 are rotated to unfold or rotate and fold, it is only necessary to slightly pull the left U-shaped frame 2 and the right U-shaped frame 3, and the operation is very convenient and quick.

[0033] The embodiment is described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiment, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the present purpose.
