[0028] Embodiment 1

[0029] In order to more clearly and conveniently describe the locking device, the locking device of this embodiment is described by taking the application in the field of bicycles as an example, and the description is given below in conjunction with the accompanying drawings.

[0030] like Figure 1-Figure 6 As shown, in order to facilitate the fixing of the number plate body 7 to the bicycle, such a structure is designed. Specifically, a bicycle includes a number plate body 7 and a bicycle frame 8, and also includes a locking device, which includes a connecting member 1, a first supporting member 2, a second supporting member 3 and a locking member 4; the connecting member 1 can be deformed to form a circular ring to form an annular accommodating cavity 9; the first supporting member 2 and the second supporting member 3 are respectively fixed to one side of both ends of the connecting member 1; the locking member 4 passes through the first supporting member 2, the connecting member 1, and the number plate body 7 and is locked with the second supporting member 3 to achieve the fixing of the connecting member 1 and the number plate body 7 to the bicycle frame 8.

[0031] In this embodiment, the locking member is preferably a screw 4, which is screwed and fixed to the second support member 3 after passing through the first support member 2, the connecting member 1 and the number plate body 7. In this embodiment, the second support member 3 is directly provided with an internal thread.

[0032] Preferably, in order to increase the stability of the internal and external threaded connection, an internal threaded sleeve 5 is provided on the second support member 3, and one end of the screw 4 is fixedly connected to the internal threaded sleeve 5 by threading.

[0033] The arrangement of the internal thread sleeve 5 is described in detail. The internal thread sleeve 5 and the second support member 3 are arranged together through a rubber encapsulation process.

[0034] It can be imagined that, for the convenience of installation, the connecting member 1 , the first supporting member 2 and the number plate body 7 are all provided with through holes 6 that cooperate with the screws 4 .

[0035] Since the bicycle frame 8 is generally italic, in order to ensure that the connecting member 1 and the number plate body 7 are roughly parallel to the ground and maintain aesthetics, an arc portion 103 is provided; specifically, the connecting member 1 includes a first connecting portion 101 and a second connecting portion 102, and the first connecting portion 101 and the second connecting portion 102 are transitionally connected by the arc portion 103.

[0036] Specifically, in order to facilitate deformation, the connecting member 1 is a thin body.

[0037] In order to prevent the connecting member 1 from excessively interfering with the first support member 2 and the second support member 3 after deformation, that is, to prevent the connecting member 1 from breaking due to friction at the contact parts with the first support member 2 and the second support member 3, the first support member 2 and the second support member 3 have a slope 10 on the end face close to the connecting member 1.

[0038] In order to maintain approximately parallelism with the sides of the curved portion 103 after bending and maintain consistency and aesthetics, the first support member 2 and the second support member 3 are substantially in the shape of a parallelogram.

[0039] Specifically, the first support member 2, the second support member 3 and the connecting member 1 can be fixed by bonding, snapping, plugging or ultrasonic welding. Since the first support member 2, the second support member 3 and the connecting member 1 are all made of plastic, ultrasonic welding is used in this embodiment.

[0040] During manufacturing, the first support member 2 and the second support member 3 are fixed to the connecting member 1 by ultrasonic welding.

[0041] During installation, bend the connecting member 1, put it on the bicycle frame 8, then pass the screw 4 through the through hole of the first support member 2, the through hole of the connecting member 1, and then through the through hole of the number plate body 7, and then through the through hole of the connecting member 1, and then screwed with the second support member 3, so that the number plate body 7 is squeezed in the connecting member 1, achieving friction extrusion, and realizing the stable installation of the number plate body 7.

[0042] Embodiment 2

[0043] As another embodiment, the locking member can also be a fixed pin. It can be imagined that the pin passes through the first support member 2, the connecting member 1, and the number plate body 7 and is locked with the hole of the second support member 3 through interference fit, so as to fix the number plate body 7 to the bicycle frame 8 through the connecting member 1.

[0044] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection required by the present invention.
