Abstract
The invention discloses a folding device for a multi-functional support. The folding device comprises the support, a transverse support, an air pump assembly, a positioning block and a fixing block assembly. The transverse support is arranged between two supporting legs of the support. A clamping plate assembly and a handle are arranged at the upper end of the support, and connecting pipes are arranged on the two sides of the support. The fixing block assembly is sleeved outside the connecting pipes, the fixing block assembly comprises two fixing blocks, and each fixing block is provided with a first pawl and a second pawl. The two ends of the air pump assembly are connected with the transverse support and the positioning block respectively. Due to the facts that the fixing block assembly and the clamping plate assembly are arranged on the two sides of the support and the air pump assembly is connected with the transverse support and the positioning block, the support is folded with more than two different heights due to the mutual matching of all the components, so that the support is suitable for different actual needs. Due to a hook and a hook shaft on the supporting legs, the situation that the support rebounds and sets up again after completely folded due to the fact that the support plays a role in supporting can be prevented. The folding device for the multi-functional support is compact in structure, easy and flexible in operation and convenient to store, and space is saved.

Embodiment
Below in conjunction with accompanying drawing the present invention is done further explanation.
Extremely shown in Figure 6 as Fig. 1, the folding device of a kind of multiple bay of the present invention, comprise support, horizontal support 1, air pump assembly 4, positioning block 15 and fixed block assembly, be provided with horizontal support 1 between two supporting legs of described support, the upper end of support is provided with clamp assembly 3 and handgrip 2, and the both sides of support are equipped with connecting tube 8; Be with fixing-assembly outside the described connecting tube 8, fixing-assembly comprises fixed block 10, and the two ends of fixed block 10 are respectively equipped with first ratchet 6 and second ratchet 7; The two ends of described air pump assembly 4 are connected to horizontal support 1 and positioning block 15.
In the present embodiment, support is fixed in by fixed base 9 in the two ends of connecting tube 8; Described air pump assembly 4 comprises plug 43 and is arranged at first permanent joint 41 at plug 43 two ends, second permanent joint 42 respectively that described first permanent joint 41 is connected with positioning block 15 with horizontal support 1 respectively by outer-hexagonal bolt 14 with second permanent joint 42.
In the present embodiment, clamp assembly 3 comprises strengthens supporting 32, and strengthen supporting 32 both sides and be provided with handgrip clamp 33 and handgrip fixed block 31, and handgrip clamp 33 curved platy structures, handgrip clamp 33 1 ends are fixed in strengthens supporting 32, and the other end is free end; Described handgrip 2 is U-shaped, and the two side portions of handgrip 2 all passes handgrip fixed block 31 successively and support and suitable with reinforcement supporting 32 is fixed in by latch in spring 12 backs.
Wherein, described support one supporting leg is provided with hook 5, and another supporting leg of this supporting leg homonymy is provided with and links up with 5 suitable hook axles 16, and the side of support is provided with handrail 13.
In practical operation, when the needs support is in first kind of height, in air pump assembly 4, charge into a certain amount of gas (for example nitrogen), air pump assembly 4 is played a supporting role under the effect of gas, this moment, first ratchet 6 of fixed block 10 was conflicted with the free end of handgrip clamp 33, stoped the downward sedimentation of support.
When the needs folding rack, pulling handrail 13 makes first ratchet 6 not contact with handgrip clamp 33, at this moment, the residing state of handgrip clamp still can hinder the motion of fixed block, pull on and start to make 2 handgrip fixed block 31 under the effect of power, move along with direction that handgrip 2 moves, so that drive the movement of whole clamp assembly 3, this moment, handgrip clamp 33 free ends up turned over, when handgrip clamp 33 up arrives certain position, first ratchet 6 breaks away from fully with handgrip clamp 33, this moment, support can descend, and it is inconsistent with handgrip clamp 33 at this moment to unclamp handgrip 2 back second ratchets 7, support then be in second kind highly constant.
When the complete folding rack of needs, only need pull on and start 2, make support continue sedimentation, air pump assembly 4 is not enough to support entire bracket because of the effect of external force in the whole process of support sedimentation.To link up with 5 at last and hook hook axle 16, and prevent from rebounding after support external force from disappearing with this and prop.
The above only is preferred implementation of the present invention; be noted that for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
