Detailed Description

The present application is described in further detail below with reference to figures 1-6.

Referring to fig. 1 and 2, the embodiment of the present application discloses a bicycle seat locking device, which includes a hoop 1, wherein the hoop 1 is integrally formed in a circular ring shape with an opening, and has two opposite first locking ends 11 and second locking ends 12, and the hoop 1 can be sleeved in the opening of an outer sleeve of a bicycle. Wear to be equipped with pin pole 2 in first locking end 11 and second locking end 12, the one end that pin pole 2 wore out second locking end 12 is provided with the external screw thread and the cooperation is installed lock nut 3, and the one end rotation that second locking end 12 was kept away from to pin pole 2 is connected with locking handle 4, and the tip of locking handle 4 keeps away from the surface butt of second locking end 12 with first locking end 11. When the locking handle 4 rotates towards the direction close to the hoop 1, the first locking end 11 and the second locking end 12 can be driven to approach each other, so that the mouth part of the outer sleeve of the bicycle is reduced and the inner sleeve is clamped.

Referring to fig. 2, the inner surface of the hoop 1 is provided with a flange 13 near one end, and the flange 13 extends in a radial direction on the inner surface of the hoop 1. Correspondingly, be close to the tip at the bicycle outer tube and can be provided with the protrusion structure with flange 13 matched with, when the outer tube was located to staple bolt 1 cover, the protrusion structure can be spacing to staple bolt 1, prevents staple bolt 1 along the outer tube landing.

Referring to fig. 2 and 3, the locking nut 3 includes a nut body 31, a handle 32 is fixedly disposed on a surface of one side of the nut body 31, which is far away from the second locking end 12, a cross section of the handle 32 is in a diamond shape, four corners of the handle are all set to be round corners, and a threaded hole of the locking nut 3 penetrates through the nut body 31 and the handle 32. Compared with a regular polygon or other forms of nuts, the diamond-shaped handle 32 is more convenient to hold, and the process of screwing the nuts is more labor-saving.

Referring to fig. 2, the locking handle 4 includes a handle body 41 and a connecting end 42, the connecting end 42 has an axle hole 421, a rotating axle 5 is inserted into the axle hole 421, the rotating axle 5 and the pin rod 2 are vertically arranged and are in threaded connection or clamped connection. The connecting end 42 is provided with an opening in which the pin 2 can move relatively when the locking handle 4 is turned. When the locking handle 4 is rotated, the connecting end 42 always abuts against the first locking end 11. The axis of the shaft hole 421 formed in the connecting end 42 is not coincident with the axis of the connecting end 42, so that when the locking handle 4 rotates in a direction close to the hoop 1, the first locking end 11 and the second locking end 12 can be driven to be close to each other, and the hoop 1 can hold the outer sleeve tightly; when the locking handle 4 is rotated in a direction away from the hoop 1, the first locking end 11 and the second locking end 12 are away from each other, the holding force of the hoop 1 is reduced, and the height of the saddle can be adjusted at the moment.

The handle body 41 is arc-shaped and matched with the surface of the outer side of the hoop 1, so that the handle body 41 is more attached to the hoop 1 when the hoop 1 is in a holding state, and the human body is prevented from being scratched. The inner surface of the end of the handle body 41 far away from the connecting end 42 can be provided with a convex part 411, when the convex part 411 is abutted against the hoop 1, the inner surface of the handle body 41 and the hoop 1 can keep a certain gap, and the handle body 41 can be pulled when the height of the saddle needs to be adjusted. Here, referring to fig. 4, the width of the handle body 41 may be further set to be greater than the width of the hoop 1, so as to facilitate the force application when pulling the handle body 41.

Referring to fig. 2, a side surface of the first locking end 11 adjacent to the connection end 42 is formed in an arc shape to be fitted with the connection end 42 of the locking handle 4, so that the locking handle 4 can be prevented from rotating about the pin shaft 2.

The first locking end 11 may further be provided with an elastic pad 6 on a side surface thereof adjacent to the connecting end 42, the pin 2 penetrates through the elastic pad 6, and the elastic pad 6 may be made of a rubber material. Through setting up cushion 6, not only can compensate the clearance between the link 42 of locking handle 4 and the first locking end 11 to improve the steadiness of locking, can reduce the wearing and tearing between the link 42 of locking handle 4 and the first locking end 11 moreover.

Referring to fig. 5 and 6, in order to prevent the elastic pad 6 and the first connection end 42 from rotating relative to each other, a limiting groove 111 is formed on a surface of the first connection end 42 close to the elastic pad 6, and a length direction of the limiting groove 111 is perpendicular to an axis of the rotation shaft 5. Correspondingly, the surface of the elastic pad 6 close to the first locking end 11 is provided with a limiting protrusion 61 matched with the limiting groove 111, and the limiting protrusion 61 can be clamped in the limiting groove 111.

The application discloses bicycle saddle locking device's theory of operation does:

under the staple bolt 1 is in the state of holding tightly, when the height of needs adjustment bicycle saddle, pull locking handle 4 and rotate to the direction of keeping away from staple bolt 1, first locking end 11 and second locking end 12 keep away from each other this moment, and staple bolt 1 reduces the power of holding tightly of bicycle outer tube for interior sleeve pipe obtains the gliding space in the outer tube. When the bicycle seat is adjusted to a proper height, the locking handle 4 is pulled to rotate towards the direction close to the hoop 1, at the moment, the first locking end 11 and the second locking end 12 are close to each other, and the mouth part of the outer sleeve contracts to lock the inner sleeve.

According to the bicycle saddle locking device, the height of a bicycle saddle can be adjusted and locked by pulling the locking handle 4, so that the convenience of saddle height adjustment is improved; meanwhile, the locking nut 3 with the diamond-shaped handle 32 is arranged, so that force application is facilitated when the locking device is disassembled and assembled, and labor is saved.

The above is a preferred embodiment of the present application, and the scope of protection of the present application is not limited by the above, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
