Referring to fig. 2, 3 and 6 to 16, one embodiment of the present utility model provides a combination lock including a housing 1, a connection strap 2, a battery assembly 3, a driving mechanism 4, a control mechanism 5, a first locking member 6 and a second locking member 7; the back of the shell 1 is provided with a jack 11 in a penetrating way, and the shell 1 is connected through a rear cover plate 202 of the connecting belt 2; the first locking piece 6 is slidably arranged in the shell 1, and a locking block 61 is arranged on the first locking piece 6; the second locking piece 7 is arranged on the front cover plate 201, and a locking hole 71 is arranged on the second locking piece 7; the driving mechanism 4 is arranged inside the shell 1 and is used for driving the first locking piece 6 to slide; the control mechanism 5 is arranged on the shell 1, the control mechanism 5 is used for inputting a password, and the control mechanism 5 is used for controlling the driving mechanism 4 to be opened and closed; the battery assembly 3 is arranged on the shell 1 or the front cover plate 201 or the rear cover plate 202, and the battery assembly 3, the control mechanism 5 and the driving mechanism 4 are electrically connected; when the housing 1 is pressed against the front face of the front cover 201 and the second locking member 7 is inserted into the housing 1 through the insertion hole 11, the driving mechanism 4 drives the first locking member 6 to slide forward until the locking block 61 is inserted into the locking hole 71, thereby achieving locking; when the input code is correct, the driving mechanism 4 drives the first locking member 6 to slide reversely until the locking block 61 is separated from the locking hole 71, thereby unlocking.

As shown in fig. 14 and 15, in the locking, it is only necessary to press the housing 1 against the front surface of the front cover 201 so that the second locking member 7 is inserted into the housing 1 through the insertion hole 11 and the first locking member 6 is driven to slide by the driving mechanism 4 so that the locking block 61 is inserted into the locking hole 71, and the locking block 61 restricts the second locking member 7 from being separated from the insertion hole 11, thereby achieving the locking between the first locking member 6 (i.e., the rear cover 202) and the second locking member 7 (i.e., the front cover 201); at this time, since the locking block 61 and the locking hole 71 are both hidden inside the housing 1, and the insertion hole 11 entering the inside of the housing 1 is hidden between the housing 1 and the front cover 201, disassembly through an external device can be effectively prevented, and the safety is higher. When unlocking is needed, the control mechanism 5 can control the driving mechanism 4 to be opened only by inputting a correct password through the control mechanism 5, so that the first locking piece 6 is driven to slide through the driving mechanism 4, and unlocking is further achieved. Compared with the traditional mechanical lock structure, the locking structure combining the password and the machinery is more difficult to crack and disassemble, and the safety is higher.

Referring to fig. 6 and 13 to 15, in some embodiments of the utility model, the locking block 61 and/or the second locking member 7 are provided with a guide surface 62; the driving mechanism 4 comprises an electric driving piece 41 and an elastic resetting piece 42, and the electric driving piece 41 and the elastic resetting piece 42 are arranged inside the shell 1; when the second locking member 7 is inserted into the housing 1, the guide surface 62 forces the first locking member 6 to slide reversely until the second locking member 7 is inserted into place, and the elastic restoring member 42 forces the first locking member 6 to slide forward, thereby achieving locking; when the input password is correct, the electric driving member 41 drives the first locking member 6 to slide reversely, thereby achieving unlocking. As shown in fig. 14, when locking, only the housing 1 needs to be pressed against the front cover 201 with force, so that the second locking member 7 is inserted into the housing 1 through the insertion hole 11; during the insertion process, the first locking member 6 is automatically forced to slide reversely under the action of the guide surface 62, thereby compressing the elastic restoring member 42; as shown in fig. 15, when the locking member is fully inserted into position, the locking piece 61 on the first locking member 6 is aligned with the locking hole 71, and at this time, the first locking member slides forward under the action of the elastic restoring member 42, so that the locking piece 61 is inserted into the locking hole 71, thereby achieving locking. That is, the entire locking process can be performed manually without starting the electric driving member 41, the operation is simpler, and the power consumption of the electric power can be reduced. The guide surface 62 may have a cambered surface structure, a slant surface structure, or the like.

The specific structure of the electric driving member 41 is not limited, and the following only provides a preferred structure for reference: as shown in fig. 11 to 13, the electric driving member 41 includes a titanium wire 411 and a fixed pulley 412, and the fixed pulley 412 is rotatably mounted on a fixed shaft 15 inside the housing 1; one end of the titanium wire 411 is fixed in the shell 1, the other end of the titanium wire 411 bypasses the fixed pulley 412 and is then connected with the first locking piece 6, and two ends of the titanium wire 411 are connected with the control mechanism 5; when the input password is correct, the two ends of the titanium wire 411 are electrified, and the titanium wire 411 contracts due to heating, so that the first locking piece 6 is pulled to slide reversely; when the two ends of the titanium wire 411 are powered off, the titanium wire 411 is stretched due to cooling, namely, the initial length is recovered, and in the process of recovering the length, the first locking piece 6 slides forward under the action of the elastic resetting piece 42.

Referring to fig. 6, in some embodiments of the present utility model, the combination lock further includes a fixing plate 8, and the fixing plate 8 is disposed on the front surface of the front cover 201; the number of the insertion holes 11, the locking blocks 61 and the second locking pieces 7 is at least two, and each second locking piece 7 is connected with the front cover plate 201 through the fixing plate 8. The greater the number of the locking pieces 61 and the second locking pieces, the better the locking effect, and the less likely the locking piece is broken by an external force. In addition, the connection bridge between the second locking piece and the front cover plate 201 is realized through the fixing plate 8, so that the installation difficulty between the second locking piece and the front cover plate 201 is reduced; at the same time, the fixing plate 8 has a large surface area, so that the connection with the front cover plate 201 is easier to realize, and the firmness of the connection between the front cover plate and the front cover plate can be improved.
