Abstract
The utility model discloses a sleeve-type bicycle frame. The bar of the bicycle frame is connected with other parts of the bicycle, or a sleeve-type connecting structure is used for the connection between two of the bars, and one of the mutual connected bars is male bar and the other one is female bar. The male bar has a tenon extended outside the bar body, and the tenon and the bar body are integrated formed. The sleeve-type structure is used for the other female bar. The shape of the female bar is matching with the shape of the tenon of the male bar and arranged on the tenon. The bicycle frame has the following advantages of: 1. The male bar is integrated forming with the bar body in the two mutual connected bars and the female bar is arranged on the tenon, thus the bicycle frame is more solid and the structural hardness of the bicycle frame exceeds the intensity of the bar body. 2. The joint between the bars of the bicycle frame is more beautiful. 3. The bicycle frame structure is easier for demolition and folding, which is beneficial for the folding of the bicycle and the miniaturized development of the ordinary bicycle.
Description
Technical field
The utility model relates to the parts that two-wheeled relies on the vehicle that manpower tramples, and more specifically refers to a kind of sleeve type bicycle frame.
Background technology
Bicycle is for ordinary populace, and right and wrong Changshu is only known, and it can be used as the vehicle that people ride instead of walk, also can be for the equipment of people's outdoor activity.No matter be the walking-replacing tool or the equipment of outdoor activity, the development tendency of bicycle is, on sense organ, require attractive in appearance, moulding and color unique novel, pattern variety is various; Structurally, require firmly, simple; On volume and weight, require miniaturization, lighting, the diameter of light metal support, foldable structure, reduction front and back wheel is then adopted in miniaturization, lighting.No matter be ordinary bicycle, or folding bicycle, vehicle frame is the indispensable part of bicycle, vehicle frame comprises spider, front fork etc. as people " skeleton ".All existing bicycle racks all are the modes that adopt welding, in the cycle frame as shown in Figure 1, junction A between whippletree 11 and the slash 12 welds, and the junction B between whippletree 11 and the seat cushion thick stick 13 also welds, and transition thick stick 14 also welds with whippletree 11, slash 12.As shown in Figure 2 be the body frame structure for automotive of the ordinary bicycle of another kind of type, wherein, between whippletree 11 and the preceding thick stick 15, and also be to adopt welded structure between preceding thick stick 15 and the slash 16.Should, the spider of present Folding Bicycle or front fork all are the welded structures that adopt aluminum alloy, magnesium alloy materials, the vehicle frame of the bicycle of common self-structure or front fork then are to adopt more common steel pipe welded structure, adopt welded structure to be leveraged to the present always.But, there is following shortcoming in welded structure, be certain to stay more or less weld seam and hole space in the welding process, therefore also certainly will influence the intensity of vehicle frame weld, cause the greatly reduction of the more non-weld parent of its intensity, theory facts have proved that weld strength is below 70% of fertile material intensity.Besides, owing to adopted welded structure, be unfavorable for that folding bicycle develops to miniaturization, in a folding bicycle, support, front fork have occupied most of volume of bicycle, their size has determined to fold the volume after folding voluntarily, and therefore, welded vehicle frame has restricted the development of folding bicycle to miniaturization.
The utility model content
The purpose of this utility model is the above-mentioned shortcoming that exists at traditional cycle frame, and a kind of welding, intensity height, easy-to-dismount cycle frame sleeve-type connection structure of need not is provided.
To achieve these goals, the utility model adopts following technical scheme:
A kind of sleeve type bicycle frame, this vehicle frame comprises several thick sticks, is connected with the bicycle other parts by thick stick wherein at least, or is connected by two thick sticks wherein at least and the geometric Framework that constitutes,
Thick stick in the described cycle frame and other parts be connected and vehicle frame in be the sleeve-type connection structure between thick stick and the thick stick.
Among two thick sticks that are connected of described cycle frame sleeve-type connection structure, one is " public affairs " thick stick, another root " mother " thick stick, " public affairs " thick stick has and extends the external tenon of thick stick, tenon and thick stick body are formed in one, another root " mother " thick stick is a telescoping structure, and shape that should " mother " thick stick is suitable and be placed in the described tenon with the shape of the tenon of " public affairs " thick stick.
The tenon and the thick stick body of described " public affairs " thick stick are vertical configuration.
The angle of the tenon of described " public affairs " thick stick and the direction straight up of thick stick body is less than 90 degree.
Between tenon of described " public affairs " thick stick and the sleeve of " mother " thick stick is flush fit, and connecting bridge also is provided with set pin.
In the another kind of sleeve-type connection structure of cycle frame,
" public affairs " thick stick more than two or two can be set, and at least one " mother " thick stick, each " public affairs " thick stick has and extends the external tenon of thick stick, tenon and thick stick body are formed in one, described " mother " thick stick is a telescoping structure, and the shape of the tenon of the shape of " mother " thick stick and two " public affairs " thick sticks is suitable and be placed in described two " public affairs " thick stick tenons.
In this structure, the tenon and the thick stick body of described " public affairs " thick stick are vertical configuration.
The angle of the tenon of described two " public affairs " thick sticks and the direction straight up of thick stick body is greater than 90 degree.
Be flush fit between tenon of described " public affairs " thick stick and the sleeve of " mother " thick stick, and connecting bridge is equipped with set pin.
In technique scheme of the present utility model, mainly a thick stick is connected with the bicycle other parts in the cycle frame that will be made of several thick sticks, or by wherein being connected between two thick sticks is designed to the sleeve-type connection structure, one that is connected is " public affairs " thick stick, another root " mother " thick stick, " public affairs " thick stick has and extends the external tenon of thick stick, tenon and thick stick body are formed in one, another root " mother " thick stick is a telescoping structure, and shape that should " mother " thick stick is suitable and be placed in the described tenon with the shape of the tenon of " public affairs " thick stick.Rely on welded structure to compare with being connected between thick stick in the traditional vehicle frame and the thick stick, it has the following advantages: 1, because in two thick sticks that are connected, the tenon and the thick stick body of " public affairs " thick stick are formed in one, and " mother " thick stick is placed in the tenon again, therefore this body frame structure for automotive is more firm, and its structural rigidity has surpassed the intensity of thick stick body itself.2, the thick stick and the junction between the thick stick of vehicle frame are more attractive in appearance.3, body frame structure for automotive is convenient to dismounting and folding more, helps folding bicycle and ordinary bicycle develops to miniaturization.
