Referring to fig. 1-4, embodiments of the present invention are provided.

The utility model provides a folding support, sill bar 10 that sets up including a pair of level and with a pair of door type pole 20 that sill bar 10 is connected, door type pole 20 includes a pair of pole setting 21 and connects the ejector pin 22 on pole setting 21 top, the both ends of sill bar 10 are provided with spacing groove 30, the bottom of pole setting 21 is connected with knee 23, knee 23 passes through spacing groove 30 with sill bar 10 is articulated, sill bar 10 with the biggest contained angle of pole setting 21 is greater than 90 and is less than 180.

In the embodiment of the present invention, the folding bracket includes a bottom rod 10, a door-shaped rod 20 and a limiting groove 30. The bottom rod 10 and the door-shaped rod 20 are provided with a pair, the bottom rod 10 is horizontally placed on the ground or a bed surface, the door-shaped rod 20 is connected with the bottom rod 10 through a limiting groove 30, specifically, the door-shaped rod 20 comprises a pair of vertical rods 21 arranged in parallel at intervals and a top rod 22 connected to the top ends of the two vertical rods 21, the door height of the door-shaped rod 20, namely the height of the vertical rods 21, is at least set to be the height which can be passed by people, and the door width of the door-shaped rod 20, namely the length of the top rod 22, is adjusted according to the width of the bed surface or the width required by a user; the limiting grooves 30 are specifically arranged at two ends of the bottom rod 10, in order to keep the door-shaped rod 20 in a standing state, the bottom end of the vertical rod 21 is provided with a bent rod 23, the included angle between the bent rod 23 and the vertical rod 21 is usually larger than 90 degrees and smaller than 180 degrees, when the bottom surface of the curved rod 23 is close to the bottom of the limiting groove 30, the upright rod 21 and the door-shaped rod 20 are integrally inclined to two sides back to the bottom rod 10, and because the door-shaped rods 20 at two sides are symmetrical and identical, so that the balance and stability of the center of gravity of the entire stand can be maintained, and at the same time, in order to fold the gate pole 20 and the bottom pole 10 together, the bent pole 23 is connected to the stopper groove 30 by means of a hinge, and further, since the folding bracket folds the two gate bars 20 inwardly onto the bottom bar 10, in order to prevent the two door-shaped rods 20 from colliding during folding, the length of the vertical rod 21, i.e., the height of the door-shaped rod 20, generally does not exceed the length of the bottom rod 10.

The middle part of the groove surfaces at two sides of the limit groove 30 is provided with a coaxial limit hole, a rotatable connecting shaft 31 is arranged in the limit hole, one side of the limit groove 30, which is close to the end part of the bottom rod 10, is provided with an opening part 32 _， The opening 32 penetrates one side of the end of the bottom bar 10.

The bent rod 23 is provided with a shaft hole 231 coaxial with the limiting hole, and the connecting shaft 31 passes through the limiting hole and the shaft hole 231, and then the bent rod 23 is hinged in the limiting groove 30 through the connecting shaft 31.

In this embodiment, the middle of the groove surface of the two sides of the limiting groove 30 is provided with a connecting shaft 31, the limiting groove 30 is a strip-shaped groove, the groove direction of the groove is the same as the direction of the bottom rod 10, the groove surface is surrounded by three side surfaces of the groove, the bottom surface of the groove is provided with a groove bottom, an opening part 32 is arranged on one side groove surface of the limiting groove 30 close to the end part of the bottom rod 10, the opening part 32 is used for removing the groove surface, the opening part 32 penetrates through one side of the end part of the bottom rod 10, coaxial limiting holes are processed on the left side groove surface and the right side groove surface of the limiting groove 30, the connecting shaft 31 is conveniently connected and installed in the limiting hole, meanwhile, the supporting function of the connecting shaft 31 is also played, one side of the limiting groove 30 without the groove surface is the opening part 32, the connecting shaft 23 connected and installed in the limiting groove 30 is avoided, the bending rod 23 is conveniently placed in the limiting groove 30, the provided bending rod 31 is also used for hinging the bending rod 23 in the limiting groove 30, with the limitation of the limiting groove 30 and the connecting shaft 31, the bending rod 23 can only rotate around the connecting shaft 31 and can not move back and forth left and right along the connecting shaft 31.

The tip processing of knee 23 has semicircle terminal surface 232, the axle center of shaft hole 231 with the centre of a circle of semicircle terminal surface 232 is concentric, the bottom surface of knee 23 supports and leans on the bottom surface of spacing groove 30, the thickness of knee 23 is not more than width between the inner wall of spacing groove 30.

In order to make the bent rod 23 rotate more smoothly in the limiting groove 30, a semicircular end surface 232 is processed at the end of the bent rod 23, and the center of the semicircular end surface 232 is concentric with the axis of the shaft hole 231, so that the whole door-shaped rod 20 is not easy to be clamped in the process of being folded towards the bottom rod 10, and the labor is saved.

In the embodiment of the present invention, in order to control the rotation of the curved rod 23 within the limited angle, and simultaneously support the rotation range of the curved rod 23 when reaching the expansion limit, the bottom surface of the limiting groove 30 limits the rotation of the curved rod 23, when the folding bracket is in the expansion state, the bottom surface of the curved rod 23 abuts against the bottom surface of the limiting groove 30, and at this time, the bottom surface of the limiting groove 30 becomes the force bearing surface of the gravity generated by the inclination of the whole door-shaped rod 20, and plays a role of supporting the curved rod 23; in addition, in order to place the bent rod 23 in the limiting groove 30, the thickness of the bent rod 23, i.e., the distance from the left side surface to the right side surface of the bent rod 23, should be less than or equal to the width between the inner walls of the limiting groove 30, and in general, the thickness of the bent rod 23 may be selected to be slightly less than the width between the inner walls of the limiting groove 30, so that the left-right sliding of the bent rod 23 can be limited to a great extent, the stable connection between the bent rod 23 and the limiting groove 30 can be enhanced, and the rocking is not easy to occur.

The embodiment of the utility model provides a pair of folding bracket in the use, only need open two door type poles 20 to the maximum angle, folding bracket just can rely on the gravity of door type pole 20 self, forms stable open mode with sill bar 10, when needs fold folding bracket, only need with two door type poles 20 inwards fold can, whole folding bracket simple structure, easy to operate, it is very convenient to use.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
