Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of keys, and particularly relates to a double-sided double-row key. Background Art
[0002] A key is a common item in life and is widely used for unlocking. It is usually made of metal materials. A key with double rows of teeth has better security and is usually applied to occasions with higher security requirements. Existing double-row keys are all single-sided, with only one side having double rows of teeth and the other side having no teeth. The security and anti-theft performance of the key still need to be further improved. Content of the Utility Model
[0003] In view of the above problems, the utility model aims to provide a double-sided double-row key to solve the problem of insufficient security of single-sided double-tooth keys.
[0004] The technical problem solved by the utility model can be realized by the following technical solutions: A double-sided double-row key includes a key handle and a key rod. One end of the key handle and the key rod are fixedly connected. Two rows of key teeth are arranged on both the left and right side surfaces of the key rod, and the key teeth are arranged on the edges of the side surface of the key rod.
[0005] A convex block is arranged between the two rows of key teeth on the same side surface.
[0006] A groove is arranged between the two rows of key teeth on the same side surface.
[0007] The key handle, the key rod and the key teeth are of an integral structure.
[0008] A central groove is arranged on the center line of the front and back surfaces of the key rod.
[0009] Oblique cutting surfaces are symmetrically arranged on both sides of the end of the key rod.
[0010] Compared with the prior art, the utility model has the following beneficial effects: Double rows of key teeth are arranged on both side surfaces of the key rod of the utility model, greatly improving the security and anti-theft performance of the key compared with single-sided single-row tooth keys.

[0016] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with specific illustrations.
[0017] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "central", "end portion", "length", "outer end", etc. are based on the orientation or positional relationships shown in the drawings, and are 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 to the present utility model.
[0018] Combined with the attached Figures 1 to 4 As shown, this embodiment discloses a double-sided double-row key, including a key handle 1 and a key rod 2. One end of the key handle 1 and the key rod 2 are fixedly connected. Two rows of key teeth 3 are provided on both the left and right side surfaces of the key rod 2. The key handle 1, the key rod 2 and the key teeth 3 are of an integral structure and are made of a metal material, with a stable structure and not easily broken. The key teeth 3 are arranged on the edge of the side surface of the key rod 2, and the tooth shapes of the two rows of key teeth 3 are different.
[0019] A groove 4 (as shown in Figure 1 , Figure 2 ) or a bump 5 (as shown in Figure 3 , Figure 4 ) is provided between the two rows of key teeth 3 on the same side surface.
[0020] A central groove 6 is provided on the center line of the front and rear surfaces of the key rod 2. Beveled surfaces 7 are symmetrically provided on both sides of the end portion of the key rod 2.
[0021] Both side surfaces of the key rod 2 of the present utility model are provided with double-row key teeth, which greatly improves the security and anti-theft performance of the key.
[0022] The above is only a preferred embodiment of the present utility model, and does not impose any form of limitation on the utility model. Any simple modification, equivalent change or modification made to the above embodiments based on the technical principle of the present utility model still falls within the scope of the technical solution of the present utility model.
