[0004] The existing foldable door prop column needs to pay attention to the directional problem when in use, that is, the side with the hinge is arranged away from the door; if the side with the hinge is arranged close to the door, the press-type unlocking assembly does not play a stable locking role after actual stress, causing the two column rods to rotate along the folding direction of the hinge, which destroys the above-mentioned triangular support structure and causes the door prop column to lose the safety blocking function. SUMMARY

[0005] In view of the deficiencies in the above problems, the utility model provides a better stability foldable door prop column.

[0006] To achieve the above-mentioned purpose, the utility model provides a better stability foldable door prop column, which comprises a lower column rod and an upper column rod connected by a hinge, the bottom of the lower column rod is provided with an adjusting seat, the top of the upper column rod is provided with a support fork for being forked on the door handle, the hinge comprises a center shaft, a first hinge head and a second hinge head arranged on the center shaft, one end of the first hinge head away from the center shaft is fixedly connected to the end of the lower column rod, one end of the second hinge head away from the center shaft is fixedly connected to the end of the upper column rod, thereby forming a foldable structure, a hook groove is formed on the first hinge head, and a first extrusion surface is formed on the outer side of the hook groove, a bolt shaft is arranged in the second hinge head, and a movable rotating rod is arranged at the bolt shaft, one end of the rotating rod is provided with a hook claw matched with the hook groove, the other end of the rotating rod is in abutment with the inner wall surface of the second hinge head through a spring, the second hinge head is also provided with an integral limiting part, and a pressing piece is arranged in the limiting part, the inner end of the pressing piece is in abutment with the surface of the rotating rod, and the outer end of the pressing piece extends to the outside of the upper column rod.

[0007] Further, the adjusting seat comprises a base and a ball head rod, the rod end of the ball head rod is fixedly connected to the lower column rod, and the ball head end of the ball head rod is connected to the base through a spherical pair.

[0008] Further, the lower column rod and the upper column rod each comprise an outer cylinder and an inner rod which is slidably arranged in the outer cylinder, and the outer cylinder and the inner rod are connected through a locking mechanism to realize length adjustment.

[0009] Further, the outer side of the hook claw forms a second extrusion surface.

[0010] Further, the pressing piece comprises a cylindrical shaft and a shaft shoulder, and the limiting part and the upper column rod are each processed with a through hole matched with the cylindrical shaft.

[0011] The utility model has the beneficial effects that relative to the prior art:

[0012] The hook claw and the hook groove are locked to each other to realize the locking of the hinge, and the lower column rod and the upper column rod cannot rotate relative to each other without being pressed and unlocked by a person, so that the foldable door support column does not need to pay attention to the direction and is more convenient to use.
