DETAILED DESCRIPTION

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figure 1 As shown, a foldable support platform of the present invention includes a platform 1 and a plurality of folding mechanisms 3 and support columns 4 corresponding to each other; the support columns 4 are all assembled on the lower end of the platform 1 through the corresponding folding mechanisms 3, and can be folded and fitted onto the lower end surface of the platform 1, or opened perpendicular to the platform 1.

[0023] The foldable support platform of the present invention is foldable. When needed, the support column 4 is opened perpendicular to the platform 1 to support the platform 1. When not needed, the support column 4 can be folded and attached to the lower end surface of the platform 1 for easy storage.

[0024] like Figure 2 As shown, the number of support columns 4 can be determined according to the shape of the platform 1. For example, when the platform 1 is rectangular, there can be four support columns 4, which are respectively arranged on four sides.

[0025] There are many structures of the folding mechanism 3, which are not limited here. In this embodiment, the folding mechanism 3 includes a rotating seat 31 and a fixed seat 32. The fixed seat 32 is L-shaped, one end of the fixed seat 32 is fixed to the edge of the platform 1, the other end of the fixed seat 32 is hinged to one end of the rotating seat 31, and the other end of the rotating seat 31 is fixedly connected to the top of the support column 4. The support column 4 is rotated, and the rotating seat 31 rotates around the fixed seat 32 so that the support column 4 is folded on the back of the platform 1. There are many ways to hinge the other end of the fixed seat 32 with the upper end of the rotating seat 31, for example: the other end of the fixed seat 32 and the rotating seat 31 are both provided with a rotating hole for a rotating shaft 34 to pass through, and can also include a fixing hole 412 for a fixing rod 33 to fix to a preset position.

[0026] There are many structures of the support column 4, which are not limited here. In the present embodiment, the support column 4 may include a shell 41, a movable column 42 and a locking mechanism 43. The shell 41 is in the shape of an elongated strip, and the bottom end of the shell 41 is open. One end of the movable column 42 slides in the shell 41 along the length extension direction of the shell 41 through this open position, and can be fixed in the shell 41 by the locking mechanism 43.

[0027] like Figure 3As shown, there are various structures of the latch 432, which are not limited here. In this embodiment, the shell 41 can be provided with a slide groove 411 and a plurality of fixing holes 412 along the length extension direction of at least one side wall of the shell 41, and the plurality of fixing holes 412 are arranged in a row along the length direction of the shell 41 and are located on one side of the slide groove 411; the latch mechanism 43 may include a latch seat 431 and at least one latch 432, the latch seat 431 is fixed to one end of the movable column 42, the latch 432 is slidably arranged on the latch seat 431, and one end of the latch 432 is provided with at least one first protrusion in parallel The second protrusion 432b passes through the slide groove 411 and can slide along the slide groove 411 under the drive of external force, and drive the first protrusion 432a to move to a position corresponding to any one of the fixing holes 412, and when the first protrusion 432a moves to correspond to any one of the fixing holes 412, the second protrusion 432b can be pulled outward under the drive of external force, and drive the first protrusion 432a to extend into the fixing hole 412 to engage with each other, or move inward until the first protrusion 432a is separated from the fixing hole 412. When the locking mechanism 432 is driven to slide toward the side where the fixing hole 412 is located, the second protrusion 432b can be engaged with the fixing hole 412, so that the locking mechanism 43 fixes the movable column 42 at a certain position in the axial direction of the housing 41; when the locking mechanism 432 is driven to slide toward the side where the fixing hole 412 is located, the second protrusion 432b can be accommodated in the housing 41, so that the second protrusion 432b can slide along the slide groove 411 to drive the movable column 42 to slide at the same time, and when it is necessary to engage, the first protrusion 432a can be pulled outward to engage with the fixing hole 412. In this way, the user can adjust the length of the support column according to his own needs.

[0028] The locking mechanism 43 further includes at least one elastic member 433, one end of which is connected to the housing or the holder, and the other end is connected to the other end of the locking member 432. The second protrusion 432b moves inward under the drive of an external force until the first protrusion 432a is separated from the fixing hole 412, and the elastic member 433 is squeezed. When the first protrusion 432a moves to a position corresponding to any fixing hole 412 and the external force is removed, the elastic member 433 returns to its initial state and drives the first protrusion 432a to extend into the fixing hole 412 and lock. Under the action of the restoring force of the elastic member 433, the first protrusion 432a and the second protrusion 432b both move in a direction away from the housing 41, and the first protrusion 432a is locked on the fixing hole 412.

[0029] A pulley 5 may also be included, and the pulley 5 is installed on a side away from the platform when the support column 4 is folded directly below the platform 1. When the support column 4 is folded on the back of the platform 1, the pulley 5 drives the platform 1 to slide under the drive of an external force.

[0030] It may also include a plurality of guardrails 6. The platform 1 is polygonal, and the plurality of guardrails 6 are foldably arranged at the edge of each side of the platform 1, so that objects placed on the platform can be prevented from falling from the platform.

[0031] There are many structures of the guardrail 6, which are not limited here. In the present embodiment, the guardrail 6 may include a guardrail 61, a connecting rod 62 and a positioning mechanism 63; one end of the connecting rod 62 is hinged to the platform 1, and the other end is hinged to the guardrail 61. The connecting rod 62 can be flipped up and down relative to the platform 1 to a vertical state or attached to the platform, and when it is flipped upward to a vertical state, it is fixed by the positioning mechanism 63 so that the guardrail 61 is horizontally arranged above the edge of the platform.

[0032] In order to facilitate the guard bar 61 to be folded on the edge of the platform 1 without occupying too much space, a groove 13 for accommodating the guard bar 61 can be provided on the edge of the platform 1. There are various structures of the positioning mechanism 63, which are not limited here. For example, a sliding groove 131 can be provided on the side of the groove 13, and a positioning hole 132 is provided on the sliding groove 131. The positioning mechanism 63 may include a positioning rod 631 and a slider 632 arranged at one end of the positioning rod 631. The other end of the positioning rod 631 is hinged to the connecting rod 62. When the connecting rod 62 rotates upward to a preset position, the positioning rod 631 is fixed in the positioning hole 132 by the slider 632 to provide support force for the connecting rod 62. When the connecting rod 62 needs to rotate downward, the slider 632 can be pulled out of the positioning hole 132, and the connecting rod 62 can rotate downward.

[0033] like Figure 4 As shown, the platform 1 may further include a fixing mechanism 7; the platform 1 includes a first panel 11 and a second panel 12, the first panel 11 and the second panel 12 are rotatably connected, and when the first panel 11 and the second panel 12 are rotated to a horizontal position, the fixing mechanism 7 fixes them. The first panel 11 and the second panel 12 may be rotatably connected by a hinge.

In the present embodiment, the fixing mechanism 7 may include corresponding fixing ears 71 arranged on the back sides of the first panel 11 and the second panel 12, and the fixing ears 71 are arranged on the edges of the first panel 11 and the second panel 12 close to each other, and the fixing ears 71 are provided with mounting holes 72, so that when the first panel 11 and the second panel 12 are respectively rotated to be horizontal, the fixing ears 71 on the first panel 11 and the second panel 12 are in contact with each other, and the mounting rod 73 fixes the first panel 11 and the second panel 12 through the mounting hole 72, and when the mounting rod 73 is pulled out of the mounting hole 72, the first panel 11 and the second panel 12 can be rotated until the front sides of the two panels are in contact with each other.

[0035] The first panel 11 and the second panel 12 may have various shapes, which are not limited here. When the platform 1 is rectangular, the first panel 11 and the second panel 12 may be triangular.

[0036] Two handles 8 may also be included, and the two handles 8 are rotatably arranged on the lower end surfaces of the first panel 11 and the second panel 12 and close to the connection between the first panel 11 and the second panel 12. When the first panel 11 and the second panel 12 are rotated to the front sides thereof touching each other, the two handles 8 are rotated to vertical to facilitate carrying the folded platform 1 by the handles 8. In order to facilitate that the handles do not occupy too much space when the first panel 11 and the second panel 12 are rotated to horizontal, corresponding positions on the back sides of the first panel 11 and the second panel 12 are provided with receiving grooves for accommodating the handles 8 rotated to touch the back sides.
