[0017] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0018] See also Figure 1-5 The utility model provides an embodiment: an anti-theft lock, comprising a lock core 2, a lock shell 1 sleeved outside the lock core 2, and a lock beam 3 connected to the lock core 2 after passing through the lock shell 1; a wear-resistant coating is provided on the outer wall surface of the lock beam 3, and the wear-resistant coating is corundum, and is formed on the surface of the lock beam 3 by a brazing process.

[0019] In summary, by setting the wear-resistant coating, the anti-cutting ability of the lock beam can be improved to ensure the safety of the lock beam when in use. Through the actual test of our company, when the cutting machine was cutting, two cutting blades were used within two minutes, and the lock beam 3 was not cut off. In addition, the brazing process can ensure the adhesion between the diamond dust and the lock beam 3, and even if the lock falls on the ground, the diamond dust and the lock beam 3 will not fall off; in addition, in order to protect the wear-resistant coating, a sheath can also be provided on the outside of the lock beam 3, for example, a rubber sheath or a plastic sheath can be used to cover the outer wall of the lock beam 3.

[0020] Furthermore, since the first protective cover 4 is provided at one end of the lock housing 1, and the second protective cover 7 is provided at the other end of the lock housing 1; after the first protective cover 4 and the second protective cover 7 are covered on the lock housing 1, the facing surfaces of the first protective cover 4 and the second protective cover 7 are fitted together. Therefore, the lock housing 1 can be protected by two protective covers, so that the lock beam 3 of the device has the anti-cutting ability and the anti-cutting ability of the lock housing 1 is further improved; at the same time, the outer wall surfaces of the two protective covers can also be provided with a wear-resistant coating.

[0021] In addition, it also includes a positioning member 6 and a keyhole 9 provided on the positioning member 6; the positioning member 6 is connected to the lock core 2 after passing through the first protective cover 4, the second protective cover 7 and the lock case 1 through a provided latch 10. Therefore, by connecting the positioning member 6 with the lock core 2, the two protective covers can be fixed to the outside of the lock case 1, so that the installation and fixing of the two protective covers are simple and convenient.

[0022] Furthermore, since the inner wall surface of the positioning member 6 is provided with a slide groove 11, and a baffle 5 is slidably installed in the slide groove 11, and the baffle 5 slides in the slide groove 11 to open the keyhole 9 or cover the keyhole 9, the baffle 5 can be slid downward when not in use to cover the keyhole and protect the keyhole.

[0023] At the same time, since a positioning groove 8 is provided on the side of the slide groove 11, and the baffle 5 is adaptively connected to the positioning groove 8 through a positioning pin 12, the positioning groove 8 can be used to lock the position of the baffle 5 to prevent the baffle 5 from sliding freely inside the positioning member 6.

[0024] Furthermore, since there are two positioning grooves 8, when the positioning pin 12 is connected to the positioning groove 8 above the positioning member 6, it can ensure that the baffle 5 is locked in the opened position; when the positioning pin 12 is connected to the positioning groove 8 below the positioning member 6, it can ensure that the baffle 5 is locked in the closed position; wherein, the baffle 5 is exposed to the outside of the positioning member 6 after passing through the keyhole 9 through the provided protrusion, so that the user can cause the baffle 5 to slide.

[0025] In addition, the mesh number of the corundum of the wear-resistant coating is 30 meshes. The 30 mesh corundum is closely arranged and fully covered on the outside of the locking beam 3, which can prevent the locking beam from being cut by a cutting machine.

[0026] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
