Abstract
The utility model discloses a kind of bicycle saddle tube contracting mechanism, comprise base and saddle outer tube, described saddle outer tube is slidably inserted in the pilot hole of base, locating part is installed with in the bottom of described saddle outer tube, rotating in the inner chamber of saddle outer tube latch is installed, between the inwall of described saddle outer tube and latch, is provided with pull back spring.The utility model is simple and reasonable, and accurate positioning is reliable.
Description
Technical field
The utility model relates to folding bicycle parts, is specially a kind of bicycle saddle tube contracting mechanism.
Background technology
In the last few years, Electrical Bicycle, with its environmental protection, convenient, inexpensive feature, was subject to the welcome of consumers in general.For the ease of carrying and depositing, many vehicles have employed fold design, as Foldable handlebar, Foldable saddle etc. at present.
Patent CN104015841 discloses a kind of electric bicycle saddle fold mechanism, and it carries out locking location by a swingable strut bar to telescopic pipe.When deployed condition, this strut bar bottom is supported on vehicle frame, with the relative position of fixing telescopic pipe.When folding, make strut bar swing alignment guide hole, telescopic pipe just can slide downward.
But this kind of saddle fold mechanism only carries out supporting and location by strut bar bottom face, and area of contact is little, there is the inadequate failure-free problem in location.
Summary of the invention
The purpose of this utility model is to provide a kind of bicycle saddle tube contracting mechanism, and it is simple and reasonable, and accurate positioning is reliable.
Bicycle saddle tube contracting mechanism described in the utility model, comprise base and saddle outer tube, described saddle outer tube is slidably inserted in the pilot hole of base, locating part is installed with in the bottom of described saddle outer tube, rotating in the inner chamber of saddle outer tube latch is installed, pull back spring is provided with between the inwall of described saddle outer tube and latch, the lower end of described latch is outwards rotated under the effect of pull back spring, stretch out from the notch of saddle outer pipe surface, when seat pipe is in deployed condition, the locating part of described saddle outer pipe bottom is upwards conflicted with the bottom in base guide hole, and described in stretch out saddle outer tube notch lock piece be pressed on the top in base guide hole downwards, to limit the axial motion of described saddle outer tube respect thereto.
Preferably, manage in the saddle that the top of described saddle outer tube is fitted with for installing seat cushion.
Preferably, described locating part is a plastic cement door being fixed on saddle outer tube bottom.
Bicycle saddle tube contracting mechanism described in the utility model, convenient to operation.When deployed condition, carry out reliable and stable locking location by latch, a pipe effectively can be avoided to occur situation about loosening, ensure riding safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model when being in deployed condition;
Fig. 2 is the structural representation of the utility model when being in contraction state.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, and following examples, only for explaining the utility model, do not form the restriction to the utility model protection domain.
Bicycle saddle tube contracting mechanism as shown in Figure 1 and Figure 2, comprises base 1, saddle outer tube 2.In whole bicycle, the front end of described base is connected with front vehicle frame by connecting rod, and base rear end is connected with Rear frame.Described saddle outer tube 2 is slidably inserted in the pilot hole of base 1.Be installed with locating part 202 in the bottom of described saddle outer tube 2, locating part 202 described in the present embodiment is a plastic cement door being fixed on saddle outer tube bottom.Pipe 3 in the saddle that the top of described saddle outer tube is fitted with sitting cushion, and the loose collar 204 for keeping inner and outer pipes relative position is provided with at saddle outer tube top.
Rotating in the inner chamber of saddle outer tube latch 201 is installed, pull back spring 203 is provided with between the inwall of described saddle outer tube 2 and latch 201, the lower end of described latch 201 is outwards rotated under the effect of pull back spring, stretches out from the notch of saddle outer pipe surface.
When needs shrink seat pipe, with hand, the latch 201 on saddle outer tube is inwardly pressed, overcome the application force of pull back spring 203, latch 201 is made to take in saddle outer tube bore, thus saddle outer tube 2 can be moved downward along the pilot hole of base 1, to reduce the height of saddle, the carrying being convenient to car load is deposited.For reducing height further, also can unclamp described loose collar 204, pipe in saddle 3 is down to extreme lower position, the contraction state of mechanism as shown in Figure 2.
When the seat pipe of contraction state is expanded to normal riding condition, only need upwards pull saddle outer tube 2, conflict to the plastic cement door of saddle outer tube 2 bottom and bottom, base guide hole, the locating part 202 of plastic cement material can play the effect of damping.Now the notch on saddle outer tube 2 surface exposes from upper end, base guide hole, and latch 201 outwards ejects under the effect of pull back spring, is pressed on pilot hole top, and the deployed condition of mechanism as shown in Figure 1.The axial motion up and down of visible now saddle outer tube 2 is all by stable locking.
Claims (3)
1. a bicycle saddle tube contracting mechanism, comprises base and saddle outer tube, and described saddle outer tube is slidably inserted in the pilot hole of base, it is characterized in that:
Locating part is installed with in the bottom of described saddle outer tube, rotating in the inner chamber of saddle outer tube latch is installed, pull back spring is provided with between the inwall of described saddle outer tube and latch, the lower end of described latch is outwards rotated under the effect of pull back spring, stretch out from the notch of saddle outer pipe surface
When seat pipe is in deployed condition, the locating part of described saddle outer pipe bottom is upwards conflicted with the bottom in base guide hole, and described in stretch out saddle outer tube notch lock piece be pressed on the top in base guide hole downwards, to limit the axial motion of described saddle outer tube respect thereto.
2. bicycle saddle tube contracting mechanism according to claim 1, is characterized in that: manage in the saddle that the top of described saddle outer tube is fitted with for installing seat cushion.
3. bicycle saddle tube contracting mechanism according to claim 1 and 2, is characterized in that: described locating part is a plastic cement door being fixed on saddle outer tube bottom.
