Depicted in FIGS. 1-9 is a folding frame. The folding frame 100 comprises a base 1, a plurality of support legs 2 hinged around the base 1, a plurality of extension support bars 3 hinged on the support legs 2 and capable of folding in relation to the support leg 2. To use the frame, unfold the support leg 2 in relation to the base 1 to support the base 1, unfold the extension support bars 3 in relation to the support legs 2 and extend them for support. To fold the frame for storage, retract the extension support bars 3 for folding, and fold the extension support bars 3 in relation to the support leg 2. The support legs 2 are folded bottom up in relation to the base 1, so as to reduce the overall size of the folded product for convenient transportation.

Both sides of the upper end of the support leg 2 are configured with teeth 20, every two neighboring support legs 2 are connected through meshing teeth 20, so that, when any one support leg 2 is folded or unfolded in relation to the base 1, all support legs 2 will be folded or unfolded simultaneously through the connection realized by the meshing teeth 20. This design makes operation very convenient.

A locking module 4 is configured inside the base 1 to position the relatively unfolded support legs 2. When the support legs 2 are unfolded in relation to the base 1, the locking module 4 fixes the support leg 2 inside the base 1, to avoid unexpected retraction of the support legs 2 in relation to the base 1 and guarantee safety of use. Meanwhile, the folding frame is stably supported and can provide strong support.

The locking module 4 includes a pull rod seat 41 mounted inside the base 1 and capable of moving up and down, a spring 42 sheathing the outside of the pull rod seat 41 and abutting the base 1, a plurality of locking blocks 43 hinged inside the base 1 and connected to the outside of the upper end of the pull rod seat 41. The pull rod seat 41 is pushed upward under the elastic force of the spring 42, forcing the end portion of the locking block 43 into the lock slot 21 on the upper end of the support leg 2, thus fixing the support legs 2 on the outside of the base 1, and realizing stable support of the support legs 2 unfolded in relation to the base 1. The lower end of the pull rod seat 41 is extended out of the end face of the lower end of the base 1. By pulling the pull rod seat 41 downward, the end portion of the locking block 43 is forced to leave the lock slot 21 on the upper end of the support leg 2, and the locked state is released. At this point, the support leg 2 can be folded in relation to the base 1. The folding and unfolding of the folding frame is very easy to operate, bringing great convenience to users.

The base 1 comprises a base seat 11 and a cover plate 12 covering the base seat 11, wherein, the cover plate 12 is locked with the base seat 11 through a screw.

The base seat 11 is provided with a main mounting slot 111 extending from its upper end face downward for mounting the pull rod seat 41 and a plurality of branch mounting slots 112 located outside the main mounting slot 111. The pull rod seat 41 is held inside the main mounting slot 111, and the lower end of the pull rod seat 41 is extended out of the lower end face of the base seat 11. The locking block 43 is hinged inside the branch mounting slot 112. The outside of the base seat 11 is configured with a plurality of intercommunicating holes 113 and communicated to the branch mounting slot 112. The upper end of the support leg 2 is hinged inside the hole 113 through a pin shaft 22. Because the holes 113 are intercommunicating, and the teeth 20 of every two neighboring support legs 2 can smoothly mesh with each other, the stability of the assembly is guaranteed. The bottom of the main mounting slot 111 is further configured with a sink slot 114. The spring 42 is installed inside the sink slot 114. The upper end of the spring 42 abuts the pull rod seat 41. The lower end of the spring 42 abuts the bottom of the sink slot 114.

The locking block 43 are formed with round convex columns 431 on both sides, and are hinged with the base 1 through the round convex columns 431, capable of moving up and down inside the base 1. Specifically, the round convex column 431 of the locking block 43 is hinged inside the groove configured on the inner wall of the branch mounting slot 112, so that the locking block 43 can swing up and down inside the base 1.

The end portion of the locking block 43 is configured with a hinge slot 432. And the two sides of the locking block 43 is further configured with a slide bar hole 433 going through the hinge slot 432. The outside of the upper end of the pull rod seat 41 is configured with a plurality of hinge portion 401. The side face of the hinge portion 401 is configured with a through axle hole 402. The hinge portion 401 is mounted inside the hinge slot 432 on the end portion of the locking block 43, and is capable of sliding. The axle hole 402 of the hinge portion 401 is fitted with a shaft. The end portion of the shaft goes through the slide bar hole 433 and can slide inside the slide bar hole 433. When the pull rod seat 41 is pushed upward under the elastic force of the spring 42, the hinge portion 401 drives the end portion of the locking block 43 to swing downward through the shaft, forcing the end portion of the locking block 43 into the lock slot 21 of the upper end of the support leg 2, thus realizing the locking function. When the pull rod seat 41 is pulled downward, the hinge portion 401 slides inside the slide bar hole 433 of the locking block 43 through the shaft, driving the end portion of the locking block 43 to swing upward within a sufficient space, so that the end portion of the locking block 43 leaves the lock slot 21 of the upper end of the support leg 2, thus realizing the unlocking function.

The pull rod seat 41 comprises a seat body 411, a pull rod 412 screwed on the lower end of the seat body 411, with its height in relation to the seat body 411 adjustable, and a pull ring 413 configured on the lower end of the pull rod 412 capable of sliding. The spring 42 is sheathed outside the pull ring 413, and the upper end of the spring 42 abuts the lower end face of the seat body 411. The lower end of the pull rod 412 is extended out of the lower end face of the base 1. The upper end of the pull ring 413 abuts the lower end of the base 1. To fold up the folding frame 100, the pull ring 413 can be pulled downward to release the locking, which is very convenient.

In particular, as the height of the pull rod 412 in relation to the seat body 411 is adjustable, and the upper end of the spring 42 abuts the lower end face of the seat body 411, by adjusting the height of the pull rod 412 in relation to the seat body 411, the compression degree of the spring 42 can be adjusted to control the elastic force of the spring 42, and to guarantee the stability of the locking state between the locking block 43 and the lock slot 21.

The lower end of the seat body 411 is formed with a threaded column 403. The upper end of the pull rod 412 is configured with a threaded slot 404. The threaded column 403 is screwed inside the threaded slot 404. The assembly structure is simple. By twisting the pull ring 413, the pull rod 412 can be driven to rotate, so that the depth of the threaded column 403 into the threaded slot 404 can be adjusted to adjust the height of the pull rod 412 in relation to the seat body 411.

The section of the seat body 411 is in the shape of a cross, and the outside of the seat body 411 has a hinge portion 401 flexibly connected to the locking, block 43.

The lower end of the base 1 is configured with sphere surface slots 101. The upper end of the pull ring 413 is configured inside the sphere surface slot 101, and abuts the sphere surface slot 101.

The number of the support legs 2 is four. Each support leg 2 is hinged with an extension support bar 3. The support leg 2 has a containing groove 23 to contain the retracted extension support bar 3.

In summary, the upper end of the support leg 2 of the folding frame is configured with teeth 20 on both sides. Every two neighboring support legs 2 are connected by the meshing teeth 20 to move together. Thus, when one support leg 2 is folded or unfolded in relation to the base 1, all support legs 2 will be folded or unfolded simultaneously through the connection realized by the meshing teeth 20. This design for simultaneous folding is very convenient for use. When the support legs 2 are unfolded in relation to the base 1, the pull rod seat 41 is pushed upward under the elastic force of the spring 42, forcing the end portion of the locking block 43 into the lock slot 21 of the upper end of the support leg 2, thus ensuring stable position of the support legs 2 outside the base 1, and providing support to the support legs 2 unfolded in relation to the base 1. The lower end of the pull rod seat 41 is extended out of the end face of the lower end of the base 1. By pulling the pull rod seat 41 downward to force the end portion of the locking block 43 to leave the lock slot 21 on the upper end of the support leg 2, the locked state can be released. At this point, the support legs 2 can be folded in relation to the base 1. The folding and unfolding of the folding frame is very easy to operate, bringing great convenience to users.
