Abstract
A waterproof mechanism of a bicycle main shaft is a waterproof ring arranged between the bicycle main shaft and a large gear disc in a sleeved mode. The main shaft is fixed to a bicycle frame through a bearing sleeve, the large gear disc is fixed at the end portion of the main shaft, the waterproof ring is made of elastic materials, one end of the waterproof ring is arranged in the bearing sleeve in a clamped and sleeved mode, a corrugated pipe which is supported in the large gear disc in an elastic mode is formed at the other end of the waterproof ring, and corresponding to an inner ring rack on one side of the bearing sleeve, an outer ring rack which can be clamped in and attached to the inner ring rack is arranged at one end of the waterproof ring. The waterproof mechanism of the bicycle main shaft can effectively prevent water or mud or sand from invading the bicycle main shaft, ensure the normal use of a bicycle and have the practical value.
Description
Technical field
The utility model belongs to the improvement of bicycle water proof and dust proof parts, and is particularly a kind of for water proof and dust proof parts on bottom bracket bearing of bicycle.
Background technology
Cycle frame 6(is exactly the cycle frame five-way particularly at present) by bearing carrier ring 4, main shaft 1 is installed, after these main shaft 1 one ends pass large fluted disc 2, fixing with screw 7 again, the people connects on this large fluted disc 2 after tread plate by trampling, this large fluted disc 2 rotates together with bottom bracket bearing of bicycle 1, rotating by the chain-driving trailing wheel with these large fluted disc 2 engagements, realize that thus bicycle advances.But the water that bicycle is encountered in the process of walking, mud or sand and dust usually can be splashed on main shaft, particularly enter from the main shaft upper bearing sleeve that is positioned at this large fluted disc one side, can affect the bottom bracket bearing of bicycle normal operation like this.
Summary of the invention
In order to make up above deficiency, the utility model provides a kind of bottom bracket bearing of bicycle proof mechanism of water, can effectively prevent sealing, mud or sand and dust intrusion bottom bracket bearing of bicycle, has guaranteed that bicycle normally uses, and has practical value.
The technical solution of the utility model is achieved in that a kind of bottom bracket bearing of bicycle proof mechanism of water, for being placed in the water proof ring between bottom bracket bearing of bicycle and large fluted disc, this main shaft is fixed in cycle frame by bearing carrier ring, this large fluted disc is fixed in this spindle nose, this water proof ring is made by having elastic material, and water proof ring one end is snap-in is placed in this bearing carrier ring for this, and the other end forms and is convenient to elastic support in the bellows of this large fluted disc.
As further improvement of the utility model, to inner peripheral surface that should bearing carrier ring one side, this water proof ring one end has is convenient to snap in the coupling outer peripheral face that is adjacent to.
As further improvement of the utility model, the inner peripheral surface of this bearing carrier ring one side has the inner circular tooth bar, and this water proof ring corresponding end has the outer shroud tooth bar that can snap in this inner circular tooth bar.
useful technique effect of the present utility model is: a kind of bottom bracket bearing of bicycle proof mechanism of water, for being placed in the water proof ring between bottom bracket bearing of bicycle and large fluted disc, this main shaft is fixed in cycle frame by bearing carrier ring, this large fluted disc is fixed in this spindle nose, this water proof ring is made by having elastic material, and this water proof ring one end is snap-in to be placed in this main shaft upper bearing sleeve, and other end formation is convenient to elastic support in the bellows of this large fluted disc, be set on this bottom bracket bearing of bicycle and fixedly the time when this large fluted disc like this, this large fluted disc also compresses the bellows part on this water proof ring, effectively prevented water, the intrusion of mud or sand and dust.
Further, the inner peripheral surface of this bearing carrier ring one side has the inner circular tooth bar, this water proof ring corresponding end has the outer shroud tooth bar that can snap in this inner circular tooth bar, design has guaranteed that this water proof ring one end can snap in and be fixed in the main shaft upper bearing sleeve by close-fitting like this, has prevented come off bearing carrier ring on this main shaft of water proof ring.

The specific embodiment
In conjunction with Fig. 3, Fig. 4, Fig. 5 and Fig. 6, below be described in detail:
A kind of bottom bracket bearing of bicycle proof mechanism of water, for being placed in the water proof ring between bottom bracket bearing of bicycle 1 and large fluted disc 2, it is exactly the cycle frame five-way particularly that this main shaft is fixed in cycle frame 6(by bearing carrier ring), this large fluted disc is fixed in this spindle nose, this water proof ring 3 is made by having elastic material, and these water proof ring 3 one ends are snap-in to be placed in this bearing carrier ring 4, and other end formation is convenient to elastic support in the bellows 31 of this large fluted disc 2, has effectively prevented the intrusion of water, mud or sand and dust.
Inner peripheral surface that should bearing carrier ring 4 one sides is had inner circular tooth bar 41, and these water proof ring 3 one ends have is convenient to snap in the outer shroud tooth bar 32 that is adjacent to this inner circular tooth bar 41.Design has like this guaranteed that this water proof ring 3 one ends can snap in and be fixed in this bearing carrier ring 4 by close-fittings, has prevented come off bearing carrier ring 4 on this main shaft 1 of water proof ring 1.
