Technical Field

The utility model relates to a technical field about the aspect of bicycle seat pole's structure especially relates to a connecting rod formula seat pole of moving away to avoid possible earthquakes that has simple structure, can effectively deal with the change of various specifications and can reduce efficiency such as stock pressure by a wide margin.

Background

Generally known link type shock absorbing seat post, as shown in taiwan patent No. M572852, is mainly to connect two ends of an upper link and a lower link between a seat tube and a seat cushion respectively in a swinging manner, locate an elastic component in an insertion tube of a seat tube, and then connect the lower link with a pull rod, so that the seat cushion can generate an elastic shock absorbing effect through the lower link, the pull rod and the elastic component. However, the elastic component is disposed in the insertion tube of the tube, which not only makes the overall structure more complicated, but also has the disadvantage of being difficult to manufacture and assemble. Moreover, the structure that the lower part of the seat pipe piece integrally extends the inserting pipe can further occupy more space when being folded and unfolded, thereby increasing the storage pressure. Particularly, seat tubes of frames of different bicycle specifications are required to be correspondingly matched with the splicing tubes of different tube diameters, so that seat tube parts of the splicing tubes of different tube diameters are required to be manufactured for customers to choose, and the change of various specifications can be met, so that the manufacturing cost is increased, the economic benefit is not met, and the storage pressure is greatly increased.

Detailed Description

Referring to fig. 1 to 5, the connecting rod type shock absorbing seat post of the present invention includes a lower seat body 10, an upper seat body 20, two connecting rods 30 and an elastic member 40, wherein:

the upper end of the lower seat 10 has a lower pivot seat 11, the lower end has a collar 12 for being sleeved on the upper end of a plug-in pipe 50, one side of the collar 12 has a groove 13, and two corresponding ear portions 14 are respectively protruded on two side walls of the groove 13, the two ear portions 14 can be screwed by at least one fastening bolt 15 to reduce the distance of the groove 13, so that the collar 12 can tighten the plug-in pipes 50 with different pipe diameters.

The upper base 20 is disposed above the lower base 10 and includes an upper pivot base 21 and a clamping base 22. The top surface of the upper pivot base 21 has an arc-shaped tooth space 23, and a through hole 230 is formed in the arc-shaped tooth space 23. The clamping base 22 comprises a lower clamping block 24, an upper clamping block 25, a gasket 26, a locking bolt 27 and a locking nut 28, the bottom surface of the lower clamping block 24 has an arc tooth surface for being correspondingly clamped on the arc tooth slot 23, a lower through hole 240 passing through is arranged on the lower clamping block 24, the upper clamping block 25 can cooperate with the lower clamping block 24 to clamp a supporting rod (not shown) at the bottom of the seat cushion, an upper through hole 250 is provided on the upper clamping block 25, the locking bolt 27 can pass through the spacer 26, the through hole 230, the lower through hole 240 and the upper through hole 250, the lock nut 28 can be screwed on the lock bolt 27 from above the upper clamping block 25 to clamp the upper and lower clamping blocks 25, 24 and position the lower clamping block 24 on the upper pivot seat 21, and the position of the lower clamping block 24 in the circular arc tooth space 23 can be adjusted by loosening and tightening the locking bolt 27 and the locking nut 28, thereby achieving the purpose of adjusting the angle of the seat cushion.

The two connecting rods 30 are respectively provided with a longitudinal rod and a transverse rod which are connected in an L shape and are oppositely arranged between the lower pivot seat 11 and the upper pivot seat 21 in a vertical direction and in a front-back direction, and the lower ends and the upper ends of the longitudinal rods of the two connecting rods 30 are respectively pivoted on the lower pivot seat 11 and the upper pivot seat 21 by four shaft pins 31.

The elastic member 40 is disposed between the two connecting rods 30, and the upper and lower ends thereof respectively abut against the two transverse rods of the two connecting rods 30, so as to provide an elastic force for swinging and resetting the two connecting rods 30.

As can be seen from fig. 4, when the upper seat 20 is pressed downward (i.e. the seat cushion is pressed downward), the two connecting rods 30 swing downward clockwise, and the two transverse rods compress the elastic element 40, when the pressure applied to the upper seat 20 is reduced or eliminated, the elastic force of the elastic element 40 will push the two transverse rods of the two connecting rods 30 to swing the two connecting rods 30 back to the original position (i.e. the seat cushion rebounds to the original position), so as to achieve the purpose of shock absorption.

As can be seen from fig. 3, when the diameter of the seat tube of the frame of the bicycle is smaller, the collar 12 of the lower seat 10 of the present invention can be sleeved with the insertion tube 50 with smaller diameter, so that the lower end of the insertion tube 50 can be inserted into the seat tube of the frame. As can be seen from fig. 5, when the bore of the seat tube of the frame of the bicycle is smaller, the collar 12 of the lower seat 10 of the present invention can also be matched with the insertion tube 50 with smaller diameter, and then a bushing 60 is sleeved between the insertion tube 50 and the collar 12 as an aid to facilitate tightening.

The utility model provides a connecting rod formula seat pole of moving away to avoid possible earthquakes locates this elastic component 40 between these two connecting rods 30, and supports respectively on two transverse bars of these two connecting rods 30 upper and lower ends to provide the elastic force that these two connecting rods 30 swing and reset, therefore the structure is comparatively simple, and the preparation is assembled moreover also comparatively easily, therefore can reduce the cost of manufacture by a wide margin. Particularly, the structure design of the binding sleeve 12 of the lower seat 10 can bind the plugging pipes 50 with different pipe diameters, so that the lower seat 10 can selectively bind the plugging pipes 50 with different pipe diameters according to different specification requirements of customers, the manufacturing is simple, and the lower seat 10 with uniform specification can be matched with frames with different specifications only by manufacturing the lower seat 10 with uniform specification to match with the plugging pipes 50 with different pipe diameters, and the lower seat 10 with different specifications does not need to be manufactured, so that the manufacturing cost can be reduced, the economic benefit can be better met, the storage pressure can be greatly reduced due to less occupied space in the collection and the placement.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
