Description
Technical field
The utility model relates to a kind of folding seat, particularly relates to the telescopic foldable chair skeleton structure of a kind of handrail.
Background technology
Foldable chair is a kind of light, stackable seat, both conveniently moves, and saves space again.Therefore be widely used in many places, as: all kinds of training organization, school and college, public place, hospital, dining room, hotel, company and family etc.In traditional foldable chair, handrail is that the folding seat of hard handrail is after folding completely, handrail and backrest often have very large volume, small and exquisite not after causing folding seat folding, go out to people and carry a folding seat and cause certain inconvenience, too increase packing cost and the cost of transportation of manufacturer simultaneously.
Utility model content
For solving the problems of the technologies described above, this practical embodiment provides a kind of folding seat, and fold back bar and backrest accounts for the excessive problem causing the inadequate compact volume and convenience of folding seat of volume to solve existing hard handrail folding chair, technical scheme is as follows:
The telescopic foldable chair skeleton structure of a kind of handrail, comprise seat body, described seat body comprises the cross pipe of seat pipe, bottom tube, Connection Block pipe and bottom tube, the scalable armrest assembly arranged on present pipe, described scalable armrest assembly is provided with foldable back assembly, and described scalable armrest assembly comprises handrail, plastic fastening, internal pin, outer foot tube; Described foldable back assembly comprises backing tube and connector; Described handrail inserts the outer foot tube be attached thereto by plastic fastening; Described internal pin inserts outer foot tube by pipe box, and described backing tube is connected with handrail tube by connector.
Preferably, described handrail is scalable.
Preferably, described internal pin is expansion link.
Preferably, described internal pin in outer foot tube can supporting armrests also separable.
Preferably, described folding seat is in folding process, and described internal pin stretches inwards to making described handrail lose support during external extension at the beginning, when described handrail be reduced to always cannot stretch inwards time, described handrail stops flexible, and described internal pin continues to shrink until described folding seat is completely closed outward.
Preferably, described plastic fastening is threeway plastic fastening.
Preferably, described backing tube is connected with described scalable armrest assembly by described connector, and described foldable back assembly is connected to the place of letting go of described scalable handrail backmost.
Handrail in common folding seat and backrest are arranged to scalable armrest assembly and foldable back assembly and are solved after folding seat folds and account for the problem that too many volume causes the inadequate compact volume and convenience of folding seat because of handrail and backrest by the utility model, make folding seat volume after folding little, flexible and convenient to use.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, the accompanying drawing that the following describes is only some embodiments recorded in the utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings:
The structural representation of a kind of folding seat that Fig. 1 provides for the utility model embodiment;
Fig. 2 is structural representation when a kind of folding seat that the utility model embodiment provides is opened completely;
Structural representation in a kind of folding seat folding process that Fig. 3 provides for the utility model embodiment;
Structural representation in a kind of folding seat folding process that Fig. 4 provides for the utility model embodiment;
Structural representation in a kind of folding seat folding process that Fig. 5 provides for the utility model embodiment;
Structural representation when a kind of folding seat that Fig. 6 provides for the utility model embodiment is completely closed.
Detailed description of the invention
In order to make those skilled in the art person understand better this creation novel in technical scheme, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the utility model protection.
As shown in Fig. 1, the telescopic foldable chair skeleton structure of a kind of handrail that the utility model embodiment provides, comprise seat body 100, seat body 100 comprises the cross pipe 150 of a pipe 120, bottom tube 190, Connection Block pipe 120 and bottom tube 190, the scalable armrest assembly arranged on present pipe 120, scalable armrest assembly is provided with foldable back assembly, scalable armrest assembly comprises handrail 110, outer foot tube 130, internal pin 140, plastic fastening 180, and foldable back assembly comprises backing tube 160, connector 170; Handrail 110 is connected with outer foot tube 130 by plastic fastening 180, plastic fastening 180 is connected with outer foot tube 130, internal pin 140 is connected with chair pin, the other end directly stretches into outer foot tube 130, backing tube 160 is connected with handrail 110 by connector 170, internal pin 140 at outer foot tube 130 inner support handrail 110, also can be separated with handrail 110.
As shown in figures 1 to 6, in folding process, internal pin 140 goes out to external extension relative to outer foot tube 130, allow handrail 110 lose support to indentation in outer foot tube 130 simultaneously, when folding seat 100 folds into a certain degree, handrail 110 is stuck on plastic fastening 180, and now handrail 110 can not down shrink, and internal pin 140 also can continue to stretch out outward, until folding seat 100 is completely closed.When folding seat is opened, internal pin 140 up contracts, and when being reduced to a certain degree, touches handrail 110, thus is ejected by the handrail 110 of complete retraction outer foot tube 130, until open completely.
Handrail in common folding seat and backrest are arranged to scalable armrest assembly and foldable back assembly and are solved after folding seat folds and account for the problem that too many volume causes the inadequate compact volume and convenience of folding seat because of handrail and backrest by the utility model, make folding seat volume after folding little, flexible and convenient to use.
The above is only detailed description of the invention of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as the protection domain of this creation.
