Description
Technical field
The utility model is relevant with bicycle, espespecially a kind of Shockproof seat tube of bicycle.
Background technology
Driving the traveling comfort of process to increase rider, at least one shock-absorbing element of usually arranging in pairs or groups in position in design, is passed to the strength of seat cushion with the vibrations reduced because road bump produces.With regard to relevant prior art, if TaiWan, China I277557 Patent Case is arranged between Five-way tube and crank shaft by shock absorbing resilient body, shock-damping structure can be produced when crank shaft rotates relative to Five-way tube and expand or shrink and damping effect is provided, in addition as TaiWan, China No. 421622 Patent Case be between Five-way tube and crank shaft large elastic body and submissile gonosome are set in the space that formed, submissile gonosome is wherein used to apply pressure, to solve the problem of the different sound in gap to large elastic body.
But in aforementioned two existing Patent Cases, constantly can be extruded and pull in the process that the elastic body being used to provide damping effect rotates relative to Five-way tube at crank shaft, the problem occurring to peel off and wear and tear is easy to like this under permanent use, even therefore may there is situation about damaging, that is, aforementioned two existing Patent Cases structurally still have the space of improvement.
Utility model content
Main purpose of the present utility model is the Shockproof seat tube providing a kind of bicycle, and it has good structural stability.
In order to reach above-mentioned purpose, Shockproof seat tube of the present utility model includes a body, an outer rigidity external member, a prestressing resilient sleeve, and rigidity external member in.The top of this body has the mounting groove that an installation portion and is located at this installation portion; This outer rigidity external member is fixed in the mounting groove of this body; This prestressing resilient sleeve is fixed in this outer rigidity external member, and the outer peripheral face of this prestressing resilient sleeve is connected to the inner peripheral surface of this outer rigidity external member; This interior rigidity external member is located in this prestressing resilient sleeve, and the outer peripheral face of this interior rigidity external member is connected to the inner peripheral surface of this prestressing resilient sleeve.
Wherein the inner peripheral surface of this outer rigidity external member has protuberance in, and the outer peripheral face of this prestressing resilient sleeve has an outer recess, and this outer recess is connected in the interior protuberance of this outer rigidity external member.
Wherein the inner peripheral surface of this prestressing resilient sleeve has an inner fovea part, and the outer peripheral face of this interior rigidity external member has a male part, and this male part is connected in the inner fovea part of this prestressing resilient sleeve.
Wherein the inner peripheral surface of this outer rigidity external member has protuberance in, the outer peripheral face of this prestressing resilient sleeve has an outer recess, this outer recess is connected in the interior protuberance of this outer rigidity external member, the inner peripheral surface of this prestressing resilient sleeve has an inner fovea part, the outer peripheral face of this interior rigidity external member has a male part, and this male part is connected in the inner fovea part of this prestressing resilient sleeve.
Wherein the outer peripheral face of this outer rigidity external member has a limit and turns teeth portion, and this limit turns the cell wall that teeth portion is connected to the mounting groove of this body.
From the above, Shockproof seat tube of the present utility model first applies prestressing to this resilient sleeve before installation, make this prestressing resilient sleeve can maintain good structural stability after installation, can't produce because of the relative start being subject to this inside and outside rigidity external member the problem dialled from or damage.
Accompanying drawing explanation
For further illustrating technology contents of the present utility model, be described in detail as follows below in conjunction with embodiment and accompanying drawing, wherein:
Fig. 1 is three-dimensional combination figure of the present utility model.
Fig. 2 is three-dimensional exploded view of the present utility model.
Fig. 3 is cutaway view of the present utility model.
Detailed description of the invention
Please first consult Fig. 1 and Fig. 2, Shockproof seat tube 10 of the present utility model includes outer rigidity external member 30, the prestressing resilient sleeve 40 of a body 20, and rigidity external member 50 in.
The top of body 20 has the mounting groove 24 that an installation portion 22 and is located at installation portion 22, and the bottom of body 20 is installed in a bar (not shown).
Outer rigidity external member 30 is made by metal material.The outer peripheral face of outer rigidity external member 30 has a limit and turns teeth portion 32, and the inner peripheral surface of outer rigidity external member 30 has four in protuberance 34 in being spacedly distributed.When assembling, as shown in Figures 2 and 3, turn by limit the cell wall that teeth portion 32 is connected to the mounting groove 24 of body 20 in the mounting groove 242 that body 20 is located at by outer rigidity external member 30 plug, outer rigidity external member 30 cannot be rotated relative to body 20.
Prestressing resilient sleeve 40 is made by rubber and apply prestressing to twist contracting mode.The outer peripheral face of prestressing resilient sleeve 40 has four in the outer recess 42 be spacedly distributed, and the inner peripheral surface of prestressing resilient sleeve 40 has four in the inner fovea part 44 be spacedly distributed.When assembling, as shown in Figures 2 and 3, prestressing resilient sleeve 40 plug is located in outer rigidity external member 30, and, the outer peripheral face of prestressing resilient sleeve 40 can be connected to the inner peripheral surface of outer rigidity external member 30, be connected in protuberance 34 in outer rigidity external member 30 by outer recess 42, to increase anchoring strength between the two simultaneously.
Interior rigidity external member 50 is made by metal material.The outer peripheral face of interior rigidity external member 50 has four in the male part 52 be spacedly distributed, when assembling, as shown in Figures 2 and 3, interior rigidity external member 50 plug is located in prestressing resilient sleeve 40, and, the outer peripheral face of interior rigidity external member 50 can be connected to the inner peripheral surface of prestressing resilient sleeve 40, is connected in the inner fovea part 44 of prestressing resilient sleeve 40 by male part 52 simultaneously, to increase anchoring strength between the two.On the other hand, the central authorities of interior rigidity external member 50 have wears groove 54, wear groove 54 wear by the bolt 60, bolt 60 is mainly used for the relative seat bow clipping plate 62 of connection two, makes these two to bend clipping plates 62 and seat can be bent 12 and fit together (as shown in Figure 1) with Shockproof seat tube 10.
From the above, principal character of the present utility model is to apply prestressing in advance to resilient sleeve 40, make resilient sleeve 40 can maintain good structural stability being installed on after between inside and outside rigidity external member 30,50, the problem dialled from or damage can't be produced, to reach the purpose of this utility model because of the relative start be subject between inside and outside rigidity external member 30,50.
