DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1-9 As shown, a password lock for the tail box of an electric vehicle comprises: a rotating member 1, which comprises a mounting portion 11 and a receiving portion 12, wherein the mounting portion 11 is connected to a lock hook 2, and a receiving groove 3 is arranged on the receiving portion 12; a password component 4, which is arranged in the receiving groove 3, and comprises a shaft body 41, a code adjustment wheel 42 which is rotatably sleeved on the shaft body 41 and has a notch 421, a password wheel 43 which is linked with the code adjustment wheel 42, and a movable limiting frame 44 which has an arc-shaped protrusion 441 and a limiting protrusion 442 which matches with the notch 421; a mounting sleeve 5, which is arranged on the outer side of the rotating member 1, and the rotating member 1 is inserted therein, and a limiting groove 51 which matches with the arc-shaped protrusion 441 is arranged on the inner ring of the mounting sleeve 5; a knob 6, which is rotatably arranged on the mounting sleeve 5 and is linked with the rotating member 1.

[0030] By adopting the above technical solution, in the present utility model, when the code wheel 42 is rotated from the code wheel 43 to the notch 421 and the limiting protrusion 442, it is in the unlocked state. At this time, the knob 6 is turned to drive the rotating member 1 to rotate, and the arc-shaped protrusion 441 is separated from the limiting groove 51. The arc-shaped protrusion 441 is squeezed by the inner surface of the mounting sleeve 5 and the movable limiting frame 44 is moved. The notch 421 provides a movable space for the limiting protrusion 442, so that the rotating member 1 can drive the lock hook 2 to rotate to achieve unlocking. Similarly, when the arc-shaped protrusion 441 is located in the limiting groove 51 and the notch 421 of the code wheel 42 is not opposite to the limiting protrusion 442, it is in the locked state. At this time, even if the knob 6 is turned, the rotating member 1 will not rotate. Among them, the arc-shaped protrusion 441 and the limiting groove 51 are matched with each other. Specifically, the limiting groove 51 is also constructed in an arc shape, and the movable limiting frame 44 can be made of plastic, which can provide a certain degree of ductility, so that it is easy to realize that the arc-shaped protrusion 441 is separated from the limiting groove 51 and the arc-shaped protrusion 441 is located in the limiting groove 51 to achieve limitation.

[0031] As an improved specific implementation method, the accommodating groove 3 is provided with a code adjusting groove 31 for accommodating the code adjusting wheel 42 for translation and a password groove 32 for accommodating the password wheel 43 for rotation, and a movable limit frame 44 is slidably arranged on the accommodating groove 3; a sheet body groove 33 is also provided in the accommodating groove 3, the sheet body groove 33 is connected with the password groove 32, a spring sheet 7 is arranged in the sheet body groove 33, and an abutting sheet 71 abutting against the password wheel 43 is provided on the spring sheet 7; a slot 52 is provided on the mounting sleeve 5 at a position corresponding to the code adjusting wheel 42, and a reset hole 61 is provided on the knob 6 at a position corresponding to the slot 52.

[0032] By adopting the above technical solution, the setting of the code adjustment groove 31 can realize the movable accommodation of the code adjustment wheel 42. In combination with the setting of the reset hole 61 and the slot 52, an external tool such as a thimble is inserted into the reset hole 61 to make the code adjustment wheel 42 move on the shaft 41, thereby realizing the replacement of the password. The setting of the spring sheet 7 makes it have a better feel when adjusting the password wheel 43. Specifically, the abutment sheet 71 will abut and get stuck in the slot of the password wheel 43.

[0033] As an improved specific implementation manner, a rotating section 62 is provided on the inner ring of the knob 6 , and a clamping block 53 for limiting the rotating section 62 is provided on the mounting sleeve 5 .

[0034] By adopting the above technical solution, the rotation angle of the knob 6 is limited within a certain range, so that the locking and unlocking of the lock hook 2 are more accurate.

[0035] As an improved specific implementation manner, a slot 111 is provided on the mounting portion 11 , and a positioning block 21 matched with the slot 111 is provided on the lock hook 2 .

[0036] By adopting the above technical solution, the locking hook 2 is easily positioned and installed, and the connection is stable.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
