Abstract
The utility model discloses a structure for connecting a lower tube with a rear lower fork of a frame. The lower tube and the rear lower fork of the frame are tightly connected, and an arc is formed at the joint of the lower tube and the rear lower fork of the frame. According to the structure for connecting the lower tube with the rear lower fork of the frame, disclosed by the utility model, the lower tube and the rear lower fork are tightly connected, the material continuity of the lower tube and the rear lower fork is enhanced, and the rigidity of a bottom bracket is enhanced; and simultaneously, a seat tube clip is integrally formed on the frame, the cost is reduced and the aesthetics is increased.
Description
Technical field
The utility model relates to the interconnection technique field of down tube and Chain stay, particularly relates to the connection structure of a kind of down tube and Chain stay.
Background technology
The following pipe of existing cycle frame is captiveed joint with Chain stay, and both also form crash-resistant vehicle frame with other parts.But following pipe has tangible straight line join domain usually with the junction of Chain stay, and both link to each other through this straight line join domain, makes this time manage and being connected of Chain stay do not had a continuity, influences the five-way rigidity.
Summary of the invention
The main purpose of the utility model is the connection structure that a kind of down tube and Chain stay are provided, and has promoted the rigidity of five-way in the vehicle frame.
The utility model proposes the connection structure of a kind of down tube and Chain stay, said pipe and Chain stay leak-tight joint down, and both joints form arc.
Preferably, said pipe down is provided with five-way with the joint of Chain stay.
Preferably, said five-way also is connected with middle pipe.
Preferably, said vehicle frame and Fixture for tube of seat are one-body molded.
Preferably, said Fixture for tube of seat is arranged in the middle pipe of said vehicle frame.
The down tube of the utility model and the connection structure of Chain stay through descending pipe and Chain stay leak-tight joint, strengthen both material continuitys, strengthen the rigidity of five-way; Simultaneously, Fixture for tube of seat is one-body molded on vehicle frame, reduce cost and increase aesthetics.
Description of drawings
Fig. 1 is the structural representation of the connection structure of down tube and Chain stay among the utility model one embodiment.
The realization of the utility model purpose, functional characteristics and advantage will combine embodiment, further specify with reference to accompanying drawing.
The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
With reference to Fig. 1, the connection structure of 10 times pipes 14 of a kind of vehicle frame with the Chain stay 17 of the utility model one embodiment is proposed.The vehicle frame 10 of this bicycle can comprise head pipe 11, on manage 12, middle pipe 13, manage 14 down, parts such as five-way 15, Seat stay 16 and Chain stay 17.
To in the prior art down pipe 14 is connected discontinuous problem with Chain stay 17, in the present embodiment, the following pipe 14 and Chain stay 17 leak-tight joints of above-mentioned vehicle frame 10, both joints formation arcs.Thereby make this time pipe 14 be connected one with Chain stay 17, be convenient to the continuity of both materials, can increase the rigidity of five-way 15 thus, the design of this arc is more attractive in appearance simultaneously.
Above-mentioned down pipe 14 is provided with five-way 15 with the joint of Chain stay 17, and pipe 13 is connected with five-way 15 in also being provided with simultaneously, manages 14 under making, Chain stay 17 and middle pipe 13 threes join with five-way 15.
Fixture for tube of seat 130 in the present embodiment can be provided with vehicle frame 10 one-body molded, can reduce whole cost and increase aesthetics.The middle pipe 13 of above-mentioned vehicle frame 10 is typically designed to hollow, and above-mentioned Fixture for tube of seat 130 can be arranged in the middle pipe 13 of this vehicle frame 10.
The connection structure of 10 times pipes 14 of above-mentioned vehicle frame and Chain stay 17 through descending pipe 14 and Chain stay 17 leak-tight joints, strengthens both material continuitys, strengthens the rigidity of five-way 15; Simultaneously, Fixture for tube of seat 130 is one-body molded on vehicle frame 10, reduce cost and increase aesthetics.
The above is merely the preferred embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification sheets and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
