Detailed Description

The seat bundle structure is in an open state as shown in fig. 1, and in a locked state as shown in fig. 2. The fittings on the seat tube bundle body mainly comprise: seat tube bank body 1, breach and locking firmware.

The gap is positioned on the seat tube bundle body so that the seat tube bundle body is in a large C shape. The two sides of the notch are connected by screws. The two sides of the notch are close to each other, so that the inner diameter of the seat tube bundle is reduced. The two sides of the notch are far away from each other, so that the inner diameter of the seat tube bundle body is enlarged.

In the illustration, the locking fastener is located at an outboard position of the seat tube bundle body opposite the direction of the notch. The locking firmware includes: first firmware 2, second firmware 3. The first fixed part 2 and the second fixed part 3 are spaced apart from each other to form an accommodating space 4. The inner side of the first fixing element 2 and the inner side of the second fixing element 3 form two sides of the accommodating space 4, and the two sides of the accommodating space 4 are preferably parallel to each other. The first fixing member 2 has a first through hole 5, and the second fixing member 3 may have a second through hole. In the illustrated embodiment, the first and second fixtures 2 and 3 each have a through hole, and the central axes of the first and second through holes are parallel to the central axis of the tube bundle body. The first through hole 5 of the first fixing member 2 is used for mounting a cylinder lock 6. The locking process is performed when the bolt 7 of the cylindrical lock 6 moves from the first fixed part 2 to the second fixed part 3; the bolt 7 is an unlocking process when moving from the second fixed part 3 to the first fixed part 2.

In other embodiments, the locking fastener may have only one first fastener 2 having the first through hole 5. Further, the position of the locking member is not limited, and may be set at any suitable position outside the seat bundle body 1.

The rotating handle 8 comprises a fixed end, a movable end and a handle body connected with the fixed end and the movable end, and the curvature of the handle body is fitted with the radian of the seat tube bundle body. The moving end is a hole feeding piece 9, and a locking hole 10 is arranged at the hole feeding piece 9. The movable end can be rotated about the fixed end within a predetermined angular range, i.e. between the movable end of the handle entering the receiving space 4 of the locking fixture and leaving the receiving space 4 of the locking fixture. The mobile end just fills the accommodation space 4.

The central angle range corresponding to the radian of the handle body is 30-360 degrees. In the locked state, the movable end of the handle is always connected to the locking fastener, and therefore the arc of the handle body corresponds to the position of the locking fastener outside the seat tube bundle body 1. For example, in the embodiment shown in the figures, the locking fastener is located at the outer position of the seat tube bundle body 1 opposite to the gap direction, and the radian of the handle body corresponds to the central angle of 180 degrees.

As shown in fig. 2 and 3, after the hole feeding piece 9 moves to the accommodating space 4, the bolt of the cylinder lock 6 passes through the capture hole 10 from the first fixing member 2, so as to achieve locking. In this embodiment, the position of the locking hole 10 is aligned with the first through hole 5 and the second through hole, and the cylindrical lock 6 passes through the first through hole 5, the locking hole 10 and the second through hole, respectively, so as to fix the hole feeding piece 9. In other embodiments, the capture hole 10 may be a recess, which opens in the direction of the first fastener 2. The position locking hole 10 can be a circumferential closed hole or an open hole, as long as the bolt 7 of the cylindrical lock 6 can prevent the rotation of the rotating handle 8 when the seat tube bundle body 1 is in a locking state. The fixed end of the handle is arranged at one side of the gap of the seat tube bundle body 1. The fixed end is also connected with a screw.

The fixed end of the rotating handle is also provided with a fine adjustment screw tool hole. Furthermore, the spatial position of the fine adjustment screw tool hole is rotated with the handle. When the handle is in an open state, the fine adjustment screw tool hole is exposed outside, and the working space of the fine adjustment screw tool hole can meet the requirement that the screwdriver stretches into the fine adjustment screw tool hole. When the handle is in a locking state, the hole position of the tool hole of the fine adjustment screw is blocked, and the working space of the fine adjustment screw cannot allow the screwdriver to extend into the hole position. Therefore, when the handle is in an opening state, the screw and the fixed end can be adjusted by the operation of the screwdriver on the fine adjustment screw tool hole.

The seat tube bundle can be used in a frame middle tube. The middle pipe of the frame is divided into a first pipe part and a second pipe part along the axial direction. The inner wall of the first pipe part is smooth, and the inner wall of the second pipe part is provided with a convex rib. The length of the sleeve is equal to the length of the first pipe portion. The sleeve is placed in the middle tube, and the outer wall of the sleeve is tightly attached to the inner wall of the first tube part. The top edge of the sleeve is provided with a flanging structure towards the outside. Because the sleeve has a flanging structure, the flanging structure of the sleeve faces outwards, and the circumference of the flanging structure is compressed by the seat tube bundle body 1. The seat tube bundle body 1 is locked with the middle tube through a locking fastener and a handle. Thus, when the saddle tube battery box is drawn out from the middle tube, the sleeve can be prevented from being taken out of the middle tube.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
