Description

Strengthen the cycling type folding chair of chair leg

Technical field

The utility model is to be related to a kind of cycling type folding chair, espespecially a kind of cycling type folding chair for strengthening chair leg.

Background technology

Cycling type folding chair be it is a kind of storage and carrying etc. very convenient chair.It please refers to Fig.1 and Fig. 2, Fig. 1 For the partial perspective view of existing cycling type folding chair, Fig. 2 is the frontal partial perspective view of existing cycling type folding chair, General cycling type folding chair includes an ontology (not shown), a seat (not shown), a back (not shown), multiple chairs Foot pad A3, multiple idler wheel A4 and two reinforcing chip A5.Ontology includes one first frame body and one second frame body, and the first frame body has two There are 2 second chair legs, 2 second chair leg to be hubbed at 2 first chair leg respectively for first chair leg A111, the second frame body.Seat is set In ontology.Back is set to ontology.These chair legs pad A3 is respectively arranged on bottom and 2 second chair of the 2 first chair leg A111 The bottom of foot.These idler wheels A4 is respectively rotatably set to the bottom of these chair legs pad A3.Two reinforcing chip A5 is respectively arranged on this The inside of 2 first chair leg A111 and with set on the bottom of the 2 first chair leg A111 chair leg pad A3 be spaced a distance.

However, because there is the relationship of idler wheel A4 below the first frame body so that the endurance of the first frame body is more insufficient and It is easily broken off, so must strengthen with the chair leg pad A3 set on the bottom of the 2 first chair leg A111 by the two reinforcing chips A5 should The structure of the overwhelming majority of 2 first chair leg A111, improves the endurance of the first frame body.

But because the two reinforcing chips A5 and one section of the chair leg pad A3 intervals set on the bottom of the 2 first chair leg A111 away from From relationship, so at least part of structures of 2 first chair leg A111 not by the two reinforcing chips A5 and set on this 2 first The chair leg pad A3 of the bottom of chair leg A111 strengthens, so that the position B, such as Fig. 2 of the most fragile as the 2 first chair leg A111 It is shown.First chair leg A111 of the first frame body of existing cycling type folding chair fails to strengthen comprehensively, and because of the first frame body There is the relationship of idler wheel A4 in lower section, though making its endurance have promotion to carry on as before has shortcoming.If the heavier-weight of user is simultaneously And existing cycling type folding chair is taken for a long time, the first frame body of existing cycling type folding chair is easy in first chair The position B of the most fragile of foot A111 is broken, and is caused anxiety safely.

Utility model content

The main purpose of the utility model is to provide a kind of cycling type folding chair for strengthening chair leg, entire first chair legs Structure strengthen comprehensively, without the position of any fragility, enhance the endurance of the first frame body, even if having rolling below the first frame body Wheel and the heavier-weight of user and this structure is taken for a long time, the first chair leg will not improve this there is a situation where being broken The safety of structure.

In order to reach purpose above-mentioned, the utility model will provide a kind of cycling type folding chair for strengthening chair leg, including One ontology, a seat, a back, multiple chair leg pads, multiple idler wheels, two reinforcing chips and two reinforced structures.
