And in order to transport the convenience, save the transportation space, reduce the cost of transportation, present seat support and chair foot are generally all separated when the transportation, in order to reduce the assembly degree of difficulty for the user, this scheme is from this and give birth to.

Disclosure of Invention

The utility model discloses it is not enough to prior art, provide a chair of convenient equipment, this kind of chair can make things convenient for quick assembles seat support and chair foot, need not with the help of other professional equipment, reduces the assembly degree of difficulty, promotes assembly efficiency.

In order to solve the technical problem, the utility model discloses a following technical scheme can solve: the utility model provides a chair of convenient equipment, includes seat support and chair foot, be provided with the whippletree on the chair foot, be provided with an at least locating lever on the whippletree, seat support bottom one side is provided with spacing hole, seat support bottom opposite side is provided with spacing portion, the locating lever tip stretches into spacing hole is spacing, the whippletree supports and leans on spacing portion, lie in on the seat support the both sides of locating lever are provided with the bellying, be provided with the spout on the bellying, sliding fit has spacing lid on the spout. This kind of chair is when the equipment, and with the tip of locating lever on the chair foot stretch into spacing hole, the whippletree of chair foot supports and leans on spacing portion, then closes the equipment of accomplishing seat support and chair foot promptly with spacing lid slip lid, and the equipment is got up conveniently fast, need not with the help of other professional equipment, reduces the assembly degree of difficulty, promotes assembly efficiency.

Among the above-mentioned technical scheme, preferred, seat support and back of the chair body coupling, be provided with a plurality of strengthening ribs on the back of the chair, the strengthening rib extends to the seat support bottom, the strengthening rib tip is regarded as spacing portion supports and leans on the whippletree.

In the above technical scheme, preferably, the sliding groove is arranged on the protruding portion, back to one side of the positioning rod, the limiting cover comprises a plate body and bending portions on two sides, and a convex strip matched with the sliding groove is arranged on the inner side surface of the bending portion.

In the above technical scheme, preferably, one end of the bending portion is provided with a notch portion matched with the cross bar, and the notch portion is attached to the cross bar.

In the above technical solution, preferably, the sliding groove is obliquely disposed on the protruding portion, and the spacing between the limiting cover and the bottom of the seat is gradually reduced in the process that the limiting cover is disposed in the sliding groove toward the horizontal bar.

In the above technical scheme, preferably, a positioning sleeve is sleeved at the end part of the positioning rod, and the positioning sleeve is matched with the limiting hole. Because the metal part machining precision is not high to the deformation of colliding with easily, establish the locating sleeve through the cover on the locating lever can be better with spacing hole cooperation, reduce because the machining precision not enough and produce the problem of rocking.

Compared with the prior art, the utility model, following beneficial effect has: this kind of chair is when the equipment, and with the tip of locating lever on the chair foot stretch into spacing hole, the whippletree of chair foot supports and leans on spacing portion, then closes the equipment of accomplishing seat support and chair foot promptly with spacing lid slip lid, and the equipment is got up conveniently fast, need not with the help of other professional equipment, reduces the assembly degree of difficulty, promotes assembly efficiency.
