Abstract
The invention discloses a locking device of a bicycle seat tube. The locking device is composed of a wedge-shaped sleeve sleeved at the lower end of the bicycle seat tube, a pull rod and a spanner, wherein the lower end of the bicycle seat tube is provided with a second wedge-shaped surface along the axial direction, and a first wedge-shaped face wedged with the second wedge-shaped face is arranged on the wedge-shaped sleeve; and the spanner is arranged above the bicycle seat tube, the upper end of the pull rod is hinged on the spanner, and the lower end of the pull rod is fixedly connected with the wedge-shaped sleeve. According to the invention, the vertical position of the seat tube is locked by using the wedge-shaped fit between the wedge-shaped sleeve and the bicycle seat tube; and in comparison with the conventional single-ring locking, the locking device disclosed by the invention has the advantages of capability of realizing locking of an upper ring and a lower ring, safety and reliability and clean and tidy appearance. The height of the seat tube can be adjusted without bending down, and even adjusted in the process of riding; and therefore, the function is very practical while running downhill.
Description
Technical field
The invention belongs to technical field of bicycles, be specifically related to a kind of bike saddle pipe locking device.
Background technology
China utility model patent CN2675516Y discloses a kind of bike saddle pipe clamp; It mainly contains cylindrical ring, elastic deformable body and bolt and forms; The inside that the seat pipe inserts the vehicle frame pipe; Cylindrical ring is sheathed on vehicle frame pipe top, and the locking end that the cylindrical ring inside face is provided with the salient point cylindrical ring is provided with elastic deformable body, and elastic deformable body is through bolt locking.Landing when this structure both can stop anchor clamps to loosen also do not need when locking, to strengthen coupling mechanism force, and clamp weight is light, cost is low.But this utility model is the gripping power when utilizing bolt that elastic body is locked to be lock onto the seat pipe on the vehicle frame pipe, and the perforate suitable for reading of vehicle frame pipe only puts on its Clamping force radially of seat pipe upper edge; Do not have axial spacing; So when friction force that applied pressure on the bicycle saddle cushion produces greater than Clamping force radially, a seat pipe can move down along the vehicle frame pipe, thus can not the locking bed pipe; Lost the locking effect of anchor clamps, and this failure conditions is inevitable.Simultaneously, elastic body is with bolt locking, clamps or when loosening the seat pipe, the swivel bolt of all need bending over takes time and effort at every turn.
For addressing the above problem, need provide a kind of and need not bend over, need be in the perforate suitable for reading of vehicle frame pipe, bike saddle pipe locking device easy and simple to handle, that locking is quick, safe and reliable.
Summary of the invention
Goal of the invention of the present invention provides a kind of bike saddle pipe locking device, and through the improvement of structure, bicycle saddle tube locking is quick, safe and reliable.
For reaching the foregoing invention purpose; The technical scheme that the present invention adopts is: a kind of bike saddle pipe locking device; Said latching device is made up of the wedge-shaped sleeve that is sheathed on the bicycle saddle tube lower end, pull bar, spanner; The lower end of said bicycle saddle tube is provided with second lozenges vertically, and said wedge-shaped sleeve is provided with first lozenges with the said second lozenges wedging;
Said spanner is located at the top of bicycle saddle tube, and the upper end of said pull bar is articulated on the said spanner, captives joint with said wedge-shaped sleeve in the lower end of said pull bar.
In the technique scheme, the inner hole surface of said lock sleeve is first lozenges; Said second lozenges is located on the outer cylinder of bicycle saddle tube.The present invention is not limited to said structure; Can also be with the outer cylinder of said wedge-shaped sleeve as first lozenges; And second lozenges is located on the inner hole surface of bicycle saddle tube lower end; And said bicycle saddle tube lower end offers seam vertically, the lower end that makes said bicycle saddle tube under the extruding of lozenges tensioner in bicycle profile tube.
In the technique scheme; The non-handle end of said spanner is a cam structure; The outer edge surface of said cam is pressed against the bicycle saddle tube upper end, and said spanner is rotationally connected through higher pair mechanism and the bicycle saddle tube formation that said cam outer edge surface and bicycle saddle tube upper surface constitute.
In the technique scheme, offer the draw-in groove that matees with said spanner on the said bicycle saddle tube, said spanner is arranged in the said draw-in groove, on the pull bar between said spanner and the bicycle saddle tube upper surface, is arranged with locking spring.
In the technique scheme, said pull bar is arranged in the endoporus of bicycle saddle tube, under the control of spanner, has upwards to strain wedge-shaped sleeve or two kinds of mode of operations of the wedge-shaped sleeve that gets loose downwards.
Preferably, said pull bar is a steel wire.Said wedge-shaped sleeve is the semi-enclosed opening pipe fitting in lower end.
Locking principle of the present invention is described below: bicycle saddle tube is inserted in the standpipe, can slide up and down along the inwall of standpipe, in order to regulate the upper-lower position of bicycle saddle cushion.Said wedge-shaped sleeve is positioned at this vertical pipe sleeve, and can slide up and down along the inwall of standpipe.Through said structure, when needs were adjusted the position of bicycle saddle cushion, conter clockwise was pulled spanner, and the standpipe endoporus moves down wedge-shaped sleeve in the promotion lower edge of pull bar, and first lozenges is removed the locking to bicycle saddle tube away from second lozenges; After the height and position of seat cushion is confirmed; Cw is pulled spanner can be so that first lozenges of the wedge-shaped sleeve of opening be pressed on second lozenges of seat pipe body; And the lateral wall of wedge-shaped sleeve is closely attached on the internal face of standpipe, thereby bicycle saddle tube is locked with respect to the inwall of standpipe.
Because the technique scheme utilization, the present invention compared with prior art has advantage:
1. the present invention utilizes the wedge-like engagement between wedge-shaped sleeve and the bicycle saddle tube to realize a locking of pipe upper-lower position, and with respect to traditional individual pen locking, the present invention is that two circles are locked up and down, and safe and reliable, outward appearance is clean and tidy.
2. the present invention need not bend over just to regulate the height that seat is managed, even when riding, can accomplish adjusting yet, and this function is practical especially in the time of descending.
