Description

Saucer lock for rolling vehicles

The present invention relates to a disc lock, and more particularly to a disc lock for rolling a vehicle.

When the rolling vehicle with the disc is parked, the user will install the disc to lock the disc to lock it, so as to prevent the rolling vehicle from being stolen; when driving, it must be Remove and store the disc lock. It is inconvenient for the user to additionally prepare a storage space for accommodating the disc lock.

In addition, when the disc lock is additionally mounted on the disc tray, the user usually has to use both hands to lock the disc lock to the disc tray. For example, the user must grasp the disc lock with one hand. The main body is temporarily fixed to facilitate driving the driving portion of the disc lock to drive the locking portion to lock the disc, so that the operation is complicated and inconvenient.

Therefore, how to invent a disc lock, in addition to the effect of preventing the rolling vehicle from being stolen, has the advantages of facilitating operation and no additional storage, and will be actively disclosed by the present invention.

It is an object of the present invention to provide a disc lock for rolling a vehicle that facilitates operation without additional storage.

To achieve the above and other objects, the present invention provides a disc lock for a rolling vehicle, which is fixed to a frame to lock a disc, and the disc lock includes: a disc body fixed to the frame. The disc body has an opening, the opening corresponding to a through hole of the frame; a locking member telescopically extending to the disc body, and when the locking member is extended, passes through the opening and the through hole to Limiting one of the plurality of limit holes of the disc tray; and a lock firmware driving portion disposed on the disc body to control the lock to expand and contract.

In the disc lock of the present invention, the rolling vehicle is an electric bicycle, and the disc tray is disposed on a rear wheel of the electric bicycle.

In the disc lock of the present invention, the lock has a shape of a circle, a square, an ellipse or a diamond.

In the disc lock of the present invention, the disc body is fixed to the frame by welding or locking.

In summary, the disc lock for the rolling vehicle of the present invention locks the disc by directly fixing to the frame, so that it is easy to operate and does not require additional storage space.

FIG. 1 is a schematic view showing the fixing of a disc lock for a rolling vehicle to a frame according to the present invention.

FIG. 2 is a cross-sectional view showing the operation of the disc lock of the present invention fixed to the frame.

FIG. 3 is a cross-sectional view showing the operation of the disc lock of the present invention fixed to the frame.

In order to fully understand the objects, features and advantages of the present invention, the present invention will be described in detail by the following specific embodiments and the accompanying drawings. Please refer to FIG. 1, which is a schematic diagram of a disc lock 1 for a rolling vehicle of the present invention. The disc lock 1 is fixed to a frame 100 of a rolling vehicle (not shown) for locking a disc tray 200. The disc lock 1 includes a disc body 10, a lock 20 and a lock driver. Part 30.

The disc body 10 is fixed to the frame 100 by welding or locking, etc., preferably to the rear wheel frame of the rolling vehicle, and the disc body 10 has an opening 11 The opening 11 corresponds to a through hole 110 of the frame 100; more specifically, the through hole 110 is larger than the opening 11.

The locking member 20 is telescoped to the disc body 10, and when the locking member 20 is extended, passes through the opening 11 and the through hole 110 to limit one of the plurality of limiting holes 210 of the disc tray 200. Thereby, the disc tray 200 is prevented from rotating, thereby achieving the effect of preventing the rolling vehicle from being stolen. The shape of the locking member 20 is not particularly limited, and may be changed according to the shape of the plurality of limiting holes 210 of the disc 200, such as a circular shape, a square shape, an elliptical shape or a diamond shape, and the like. The shape of the opening 11 and the perforation 110 also corresponds to the shape of the fastener 20.

The lock driving unit 30 is disposed on the disc body 10 to control the expansion and contraction of the lock 20, and more specifically, the lock driving unit 30 can extend or contract the lock 20 by means of a key rotation. The disc body 10 is inserted.

As shown in FIG. 2, when the fastener driving portion 30 is rotated, the locking member 20 is extended and passed through the opening 11 and the through hole 110 to limit the limiting hole 210 of the disk tray 200. The disc tray 200 cannot be rotated, and the wheels (not shown) corresponding to the disc tray 200 cannot be rotated.

As shown in FIG. 3, when the lock driving portion 30 is reversely rotated, the locking member 20 is retracted into the disc body 10, and the limiting hole 210 of the disc tray 200 is no longer limited. The disc tray 200 is arbitrarily rotated.

When the disc body 10 is fixed to the rear wheel frame of the rolling vehicle, it is advantageous for the user to operate the lock driving portion 30.

In summary, the present invention is applied to a disc lock for a rolling vehicle. Since the disc body is directly fixed to the frame, no additional storage space is required when not in use, which is convenient for the user; Since the disc body is directly fixed to the frame, the user only needs to rotate the lock driving portion with one hand, and the disc lock can be operated to define the disc to define the disc.

The invention has been described above in terms of the preferred embodiments, and it should be understood by those skilled in the art that the present invention is not intended to limit the scope of the invention. It should be noted that variations and permutations equivalent to those of the embodiments are intended to be included within the scope of the present invention. Therefore, the scope of protection of the present invention is defined by the scope of the patent application.
