Description

Open cover riser

This creation relates to a bicycle cover-opening riser which is used to adjust the angle of the handlebar and the faucet, and can quickly lock or completely release the handlebar.

Bicycle is a kind of commonly used means of transportation. It uses human pedaling as its power source, and does not need to use electricity or gasoline. It has a very environmentally friendly concept and is very suitable for use as a general transportation vehicle or a leisure sports device. And because bicycles have both energy-free and exercise effects, more and more modern people use bicycles as a means of transportation, and generally bicycles use handles to control the direction of their travel, and the handle is a handle. The seat tube is connected with the front fork tube of the bicycle, so that the cyclist can control the rotation of the front fork tube by turning the handle, and then control and change the traveling direction of the bicycle. In general, the combination between the standpipe and the handle is set in a fixed way, and does not have the function of adjusting the elevation angle. However, different users have different body shapes, so when using the standpipe and the handle in this fixed way, The user will have the problem of less comfortable use due to the problem of height difference.

However, the bicycle standpipes provided in the market today are usually tied to the upper end of the main pipe and combined with an adjustable fixing seat, and the front end of the fixing seat is provided with a hollow torsion seat. The slot is cut, and a through-shaped screw hole is arranged in the radial direction of the slot for the screw to pass through the setting position, so that the front end of the screw protrudes in front of the ring seat, and the quick release wrench is locked, and one end of the quick release wrench is formed with a cam structure, that is When the quick release wrench is rotated, the ring seat can be adjusted arbitrarily to lock or release the handle of the bicycle. However, this kind of quick release structure of the riser can only loosen the handle of the bicycle, which is in line with the user's need to adjust the angle. When modifying or repairing the handle of the bicycle, the bridle seat cannot be fully opened, which forces the grip of the handle and the brake unit to be removed. After the parts are disassembled, they can be pulled out horizontally for replacement. Therefore, the conventional bicycle quick-release riser still cannot fully meet the needs of consumers.

In view of this, the present invention provides a seat tube structure suitable for bicycles, especially a bicycle cover-opening seat tube used to adjust the angle of the handlebar and the faucet, and can quickly lock or completely release the handlebar. main target.

The main body is provided with a pair of second lugs 122; the first tightening member 11 cooperates with the tightening portion 13 to fix the handlebar 40, and the binding rod 50 is connected with the second tightening member 12 by a pivot 71 , in the embodiment shown in the figure, the pivot 71 is sleeved in the second tightening member 12 , and one end of the tie rod 50 is locked on the pivot 71 .

The pull rod 20 is connected between the first lug 112 and the second lug 122 of the standpipe 10 , and one end connected to the first lug 112 is connected to the first lug 112 through an eccentric shaft 72 Pivot connection, one end connected to the second lug 122 is detachably fixed to the second lug 122 through a fixing member 73 , and one end of the pull rod 20 connected to the second lug 122 is provided with a The long slot hole 21 allows the fixing piece 73 to pass through, and an adjusting piece 22 is screwed at the end thereof. The adjusting piece 22 can penetrate the long slot hole 21 and interfere with the fixing piece 73 . The fixing member 73 and the adjusting member 22 are threaded, and are respectively fixed to the second lug 122 and penetrated into the long slot hole 21 by screwing.

One end of the body of the wrench 30 is provided with a pair of third lugs 31 for pivoting with the first lugs 112 via the eccentric shaft 72 , and the eccentric shaft 72 can rotate with the wrench 30 to pull the wrench 30 . The tightening portion 13 and the pull rod 20 act; wherein, when the user tightens the wrench 30 toward the closing direction, the pull rod 20 can be pulled to move at the same time, so that both sides of the first slot 111 of the first tightening member 11 are moved. The bodies are abutted against each other, so that the first tightening member 11 is tightened to fix the handlebar 40 on the seat pipe 10, and at the same time, the two sides of the bodies on both sides of the second slot 121 of the second tightening member 12 are tightly compressed against each other, The second tightening member 12 is tightened to hold and fix the pivot shaft 71, thereby fixing the relative angle between the riser 10 and the tie rod 50; The tightness of the wrench 30 and the size of the first and second slots 111 and 121 are controlled at the same time, so that the first tightening member 11 can clamp the handlebar 40 and the second tightening member 12 can clamp the pivot shaft 71, in order to improve the applicability and practicability of the integral open-top riser. At this time, the appearance of the standpipe of the present invention is as shown in FIG. 1 , the spanner 30 is covered on the standpipe 10 in a closed state, and the pull rod 20 , the fixing piece 73 and the adjusting piece 22 are hidden between the spanner 30 and the standpipe 10 . The riser 10 is not exposed inside.

The riser is further provided with at least one switch, which is arranged between the riser and the wrench to control the opening or closing of the wrench. A fastener 80, the fastener 80 is fixed on the body of the wrench 30 by a fixing screw 81, the fastener 80 is also provided with a control part 82 and a buckle part 83, the control part 82 is exposed to the wrench 30, The buckle portion 83 can be extended into or out of the bottom of the pull rod 20 through the linkage of the control portion 82 ; when the wrench 30 is closed (ie, the handlebar 40 is fixed on the seat pipe 10 ), the buckle The clasp portion 83 extends below the pull rod 20 to prevent the wrench 30 from being opened arbitrarily.

In order to clearly illustrate the operation mode and effect of the present invention, when the user wants to adjust the angle of the handlebar and the faucet, or even wants to change the handlebar, he only needs to press the control part 82 with a little force, as shown in Figs. 5 and 6 , so that the buckle portion 83 leaves the bottom of the pull rod 20, and the wrench 30 can be easily opened in the opening direction to present the open state. At this time, the pull rod 20, the fixing member 73 and the adjusting member 22 are exposed, and the user can use the tool The fixing member 73 is withdrawn from the second lug 122 , as shown in FIGS. 7 and 8 , so that the pull rod 20 is separated from the second lug 122 , and can simultaneously drive the tightening portion 13 toward the wrench 30 . The opening direction is pulled open to present an open state, so that the first The tightening member 11 can be fully opened to provide replacement of the handlebar 40; when the user turns the wrench 30 again and pulls the pull rod 20 to tighten in the closing direction, the tightening portion 13 can be simultaneously pulled for tightening, and the fixing member 73 is locked on the The second lug 122 can achieve the effect of locking the handlebar 40 . In this way, the present invention achieves the effect that other components of the handlebar (such as grips, brake units, etc.) can be quickly disassembled and replaced without dismantling, which is convenient for users to replace, modify or maintain by themselves, and it is convenient for users to adjust the handlebar 40 . and the angle of the faucet, as shown in Figure 9.
