Description

Technical Field

[0001] The utility model relates to a motor lock with a variable lock tongue. Background Art

[0002] Motor lock, also known as spiritual lock, is a lock that uses motor drive to achieve automatic locking and unlocking functions. Although motor lock is a universal lock, the requirements for motor locks in different regions are obviously different. At the same time, with the changes in usage scenarios, the length of the motor lock tongue is also obviously different, and there are different regional standards. As a result, the same type of lock needs to be designed with different versions of the tongue extension length according to different regions or usage scenarios. This leads to a sharp increase in the design and mold opening costs of manufacturers, which is not conducive to improving production and processing efficiency, and increases costs. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a motor lock with a variable lock tongue, which has a simple structure and is convenient for adjusting the extended length of the lock tongue in the lock body, effectively reducing production costs and improving product adaptability.

[0004] To achieve the above-mentioned purpose, the utility model provides a motor lock with a variable lock tongue, including a lock body, a lock tongue being slidably arranged on the lock body, a drive shaft and a drive motor for driving the drive shaft to rotate being also arranged in the lock body, the drive shaft being transmission-connected to the drive motor through a gear set, one end of the lock tongue inserted into the lock body being swingably connected to a transmission arm, a plurality of matching holes being arranged at intervals along the length direction of the transmission arm on the end of the transmission arm away from the lock tongue, a crank arm being connected to the drive shaft, and a connecting protrusion for engaging with the matching hole being arranged at the end of the crank arm.

[0005] The beneficial effect of such a setting is as follows: in such a setting, a plurality of matching holes are arranged in an orderly interval along the length direction of the transmission arm at one end of the transmission arm away from the lock tongue, and on the driving shaft, a crank arm is connected, and a connecting protrusion is arranged at the end of the crank arm, and the connecting protrusion is used to accurately engage with the matching hole. In the actual working process, the driving motor is operated, and the driving shaft is driven to rotate through the gear set, so that the crank arm rotates accordingly. When the connecting protrusion on the crank arm engages with the matching holes at different positions, the swing amplitude of the transmission arm changes accordingly, and finally the extension length of the lock tongue is adjusted. This structural design greatly improves the applicability of the motor lock, and can flexibly adjust the extension length of the lock tongue according to different usage scenarios and safety requirements. It does not require additional molds, reduces production and processing costs, and has a good use effect.

[0006] As a further configuration of the present invention, the transmission arm is separately arranged to form a main body and an assembly, the main body is provided with a first combination half hole, the assembly is provided with a second combination half hole corresponding to the position of the first combination half hole, the first combination half hole and the second combination half hole are combined to form a matching hole, and the main body and the assembly are fastened together by a locking screw.

[0007] The beneficial effect of such a setting is that when the main body and the assembly are spliced, the first combined half hole and the second combined half hole are just combined to form a matching hole. The main body and the assembly are fastened together by a locking screw. This design makes it extremely convenient to position the connecting protrusion and the matching hole. In actual operation, it is only necessary to align the two and splice them, tighten the locking screw, and the installation can be completed quickly. Not only is it convenient to operate, but if adjustment or maintenance is required in the future, disassembly is also easy and simple, which is convenient for adjustment according to needs and has a good use effect.

[0008] As a further configuration of the utility model, a positioning frame is provided in the lock body, the drive shaft passes through the positioning frame and extends out of the lock body, the positioning frame has a guide protrusion extending toward the lock tongue, the lock tongue is provided with a guide groove, and the guide protrusion is slidably inserted in the guide groove.

[0009] The beneficial effect of this arrangement is that a positioning frame is reasonably arranged inside the lock body, the drive shaft is inserted into the positioning frame, and the positioning frame extends a guide protrusion toward the direction of the lock tongue. Correspondingly, a guide groove is precisely arranged on the lock tongue, and the guide protrusion can slide smoothly into the guide groove, which ensures the stable layout of the various components in the lock body and can also cooperate closely with the lock tongue to play a good guiding role. When the lock tongue is sliding, the cooperation between the guide protrusion and the guide groove can effectively prevent the lock tongue from shaking or deflecting, significantly improving the reliability of the entire structure in actual use and providing a solid guarantee for the stable operation of the motor lock.

[0010] As a further configuration of the utility model, a plurality of positioning posts are arranged in the lock body corresponding to the edge positions of the positioning frame, and connecting holes are arranged on the positioning frame corresponding to the positions of the positioning posts, and fastening screws for fastening to the positioning posts are arranged in the connecting holes.

[0011] The beneficial effect of this arrangement is that when installing the positioning frame, you only need to align the connection hole on the positioning frame with the positioning column of the lock body, and then tighten the fastening screw to achieve a stable connection between the two. This arrangement greatly ensures the stability of the positioning frame in the lock body and effectively prevents it from shaking or shifting. Moreover, since the positioning column is located at the edge of the positioning frame, the installation process and tightening operation will not interfere with other precise structures inside the lock body, ensuring that the entire lock system operates stably and efficiently.

[0012] As a further configuration of the utility model, the positioning frame is shielded on the gear set, and the positioning frame is provided with a shielding plate extending toward the driving motor.

[0013] The beneficial effect of this arrangement is that, by means of this arrangement, the positioning frame fits closely around the periphery of the gear set, and can effectively block external dust, debris and other impurities. Once dust enters the gear set, it is easy to accumulate at the meshing point of the gears, which not only affects the accuracy of the gear position, but also increases the running resistance and even causes jamming. The existence of the shielding frame and the shielding plate can effectively protect the gear set. While ensuring the stability of the gear set position, it ensures that the gears always run smoothly and unimpeded, greatly extending the service life of the gear set and providing strong support for the efficient and stable operation of the motor lock.
