Description
Technical field
The utility model belongs to bicycle accessories technical field, and in particular to a kind of titanium, aluminium alloy seat pipe.
Background technology
The effect of bicycle saddle tube is upper end connection saddle, and lower end is inserted into the middle pipe orifice of cycle frame,
Locked through Fixture for tube of seat.The most of seat pipes of in the market be all using made of aluminium alloy and Chromador material, they the characteristics of be valency
Lattice are cheap.But though Chromador seat pipe intensity is high, than great, surface must need coating treatment for it.Aluminium alloy seat pipe intensity is low,
Light specific gravity.Full titanium alloy seat pipe not only light but also high intensity, but its market price is very high.
Utility model content
The utility model solves the deficiencies in the prior art, there is provided a kind of titanium, aluminium alloy seat pipe.
Technical solution is used by the utility model：A kind of titanium, aluminium alloy seat pipe, including Aluminum alloy connector and titanium
Pipe, Aluminum alloy connector one end interference fit are pressed into the endoporus of titanium tube, and the Aluminum alloy connector is T-shaped structure,
The upper end offers semi-circular hole, and aluminium alloy semicircle supporting sleeve, the aluminium alloy semicircle support are inlaid with the semi-circular hole
Put on and be connected with aluminium alloy gland, the Aluminum alloy connector both ends are equipped with titanium alloy tie down screw, and the aluminium alloy pressure
Lid both ends are equipped with aluminium alloy cylindrical nut, the aluminium alloy cylindrical nut and the threaded hole opened up in the middle part of titanium alloy tie down screw
It is threadedly coupled.
Preferably, the aluminium alloy gland both ends are semicircular structure, and the upper end is the arcwall face of indent.
Compared to the prior art, the utility model has the advantage that：The seat pipe agent structure connector is closed using aluminium
Golden material is made, and intensity is low, light specific gravity, meets requirement of the bicycle to connector mechanical property, its main body tube is closed using titanium
Golden material is made, light-weight, corrosion-resistant, is not easy to get rusty, durable, and security is good, and Aluminum alloy connector interference
With the use of forcing press press-in titanium tube endoporus in, ensure that the perfect adaptation of titanium, aluminium alloy, and reduce the seat pipe into
This, titanium tube intensity is high, and perfection has been obtained using the advantages of in main force part, further making titanium alloy and aluminum alloy materials
Combination.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of titanium, aluminium alloy seat pipe, refering to Fig. 1, including Aluminum alloy connector 1 and titanium tube 2,1 intensity of Aluminum alloy connector
Low, light specific gravity, meets requirement of the bicycle to connector mechanical property, and titanium tube 2 is light-weight, corrosion-resistant, is not easy to get rusty, prolonged resistance to
With, and security is good.In the endoporus of 1 one end of Aluminum alloy connector interference fit press-in titanium tube 2, Aluminum alloy connector 1
In endoporus of the interference fit using forcing press press-in titanium tube 2, the perfect adaptation of titanium, aluminium alloy ensure that.The aluminium alloy connection
First 1 is T-shaped structure, in order to enable Aluminum alloy connector 1 is fixed with aluminium alloy gland 4 easy to connection, in Aluminum alloy connector 1
Upper end offers semi-circular hole 11, and aluminium alloy semicircle supporting sleeve 3, the aluminium alloy semicircle branch are inlaid with the semi-circular hole 11
Aluminium alloy gland 4 is connected with support set 3,1 both ends of Aluminum alloy connector are equipped with titanium alloy tie down screw 5, and the aluminium
4 both ends of alloy gland are equipped with aluminium alloy cylindrical nut 6, and the aluminium alloy cylindrical nut 6 is opened with the middle part of titanium alloy tie down screw 5
If threaded hole 51 be threadedly coupled.
With continued reference to Fig. 1,4 both ends of aluminium alloy gland are semicircular structure 41, and the upper end is the arcwall face 42 of indent.
During use.Aluminum alloy connector 1 has fastened cushion through fixed screw, and titanium alloy tube is inserted into vehicle frame in pipe orifice,
Fixture for tube of seat fixes the height of seat pipe.
The preferred embodiment of above-described embodiment, simply the utility model, is not used for limiting the implementation model of the utility model
Enclose, therefore all equivalent variations done with content described in the utility model claims, should all be included in the utility model right will
Within the scope of asking.
