[0042] like Figure 1-12As shown, a lock head structure with a gear sense comprises a lock housing 1, a lock core 2 rotatably arranged in the lock housing 1, and a side pin 3. The lock core 2 is provided with a plurality of blade slots 21 arranged parallel to its axial direction and perpendicular to the axis, and a blade 4 is slidably arranged in each blade slot 21. The blade slot 21 is perpendicular to the axial direction of the lock core 2, and a pair of blades 4 are arranged in each blade slot 21. A blade reset member 5 for resetting the blade 4 is provided in the lock core 2, and the thrusts of the blade reset members 5 of the pair of blades 4 are preferably in opposite directions, so that the force is more uniform. The side pin 3 is arranged parallel to the axial direction of the lock core 2, and the lock core 2 is provided with a through groove 22 for inserting the side pin 3. A lock port 41 is provided on each blade 4 facing the side pin 3, and a key 10 is inserted into the blade 4. The first plug hole 42 is provided with a protruding lock tooth 421, and the lock tooth 421 of each blade 4 is at a different position. The inner wall of the lock housing 1 is provided with a first locking groove 11 and a second locking groove 12 that cooperate with the side pin 3 along its circumference. When in the locked state, the side pin 3 is located in the first locking groove 11, and when in the unlocked state, the side pin 3 is located in the second locking groove 12. It also includes a side pin reset member 6 for providing the side pin 3 with a reset force in the direction of the first locking groove 11 or the second locking groove 12, so that the lock head structure has a good feel when operating. When the side pin 3 enters the first locking groove 11 or the second locking groove 12, the side pin 3 touches the locking groove and makes a sound, giving feedback, so that the user can confirm whether it is locked or unlocked in place at this time. The depth of the first locking groove 11 is greater than the depth of the second locking groove 12. When in the locked state, the structure is stable and the anti-theft effect is good. The depth of the second locking groove 12 is shallow, which is convenient for the side pin 3 to enter and exit the second locking groove 12. When unlocking, insert an appropriate key, and the interaction between the tooth groove on the key and the lock tooth 421 on the blade 4 forces the position of the blade 4 to change until the lock hole 41 on the blade 4 is in the same straight line. At this time, turning the key drives the lock cylinder 2 to rotate in the lock shell 1, and the side pin 3 will slide into the lock hole 41 and disengage from the first locking groove 11 to complete the unlocking. When the lock cylinder 2 rotates to the second locking groove 12, the side pin 3 will slide into the second locking groove 12. When the key drives the lock cylinder 2 to rotate back to its original position, under the action of the side pin reset member 6, the side pin 3 is re-engaged in the first locking groove 11. When the key is pulled out, the position of the blade 4 is forced to reset and change through the mutual guiding action of the tooth groove on the key and the lock tooth 421 on the blade 4. The lock holes 41 on each blade 4 are no longer in the same straight line, which limits the radial displacement of the side pin 3 and completes the locking.
[0043] One side of the side pin 3 in the unlocking direction is set as a slope, the side of the first locking groove 11 opposite to the slope is also set at an angle, the outer side of the side pin 3 is set at a right angle, the bottom of the first locking groove 11 is set at a right angle to the other side, and the two side edges of the second locking groove 12 are also set at an angle. When the lock core 2 is rotated, the side pin 3 can smoothly enter and exit the first locking groove 11 or the second locking groove 12 without jamming.
[0044] The lock core 2 also includes a cover 7 that rotates synchronously with the lock core 2. The cover 7 is provided with a second insertion hole 71 for inserting a key. The lock core 2 is provided with a baffle 23 that is movably provided at a position corresponding to the second insertion hole 71. The baffle 23 is turned into the lock core 2 under the drive of the key to allow the key to be inserted. The lock core 2 is also provided with a baffle reset member 24 that drives the baffle 23 to reset. The arrangement of the baffle 23 can effectively prevent debris from entering the lock core 2 and affecting unlocking. The lock core 2 is provided with a mounting boss 25 and a third insertion hole 26. The third insertion hole 26 is arranged corresponding to the second insertion hole 71 and is located on one side of the mounting boss 25. The mounting boss 25 is provided with a mounting groove 251. A mounting rod 252 is arranged in the mounting groove 251. The baffle 23 and the baffle reset member 24 are both installed on the mounting rod 252. The baffle 23 is arranged to rotate relative to the mounting rod 252. Under the drive of the key, the baffle 23 rotates around the mounting rod 252 and fits against the side wall of the mounting boss 25 to expose the lock core 2. The third insertion hole 26 is exposed, and the baffle reset member 24 is set with a torsion spring, which has a simple structure and is easy to install. When the key is inserted, the baffle 23 is pushed into the lock shell 1, and the baffle 23 rotates around the mounting rod 252. When the baffle 23 rotates to fit the side wall of the mounting boss 25, it means that the baffle 23 has rotated into place, and the key can be inserted from the third insertion hole 26 and inserted into the first insertion hole 42. After the key is pulled out, the baffle reset member 24 automatically resets the baffle 23 and covers the third insertion hole 26 to prevent debris from entering and affecting subsequent unlocking.
[0045] A limiting shaft 27 is provided on the outer wall of the lock core 2, and a limiting groove 13 is correspondingly provided on the lock housing 1. The limiting shaft 27 is located in the limiting groove 13, and when the lock core 2 rotates, the limiting shaft 27 slides in the limiting groove 13, which can play a limiting and guiding role, so that when the lock core 2 rotates under the drive of the key, the structure is stable. The limiting groove 13 is arranged opposite to the first locking groove 11 and the second locking groove 12, and the distance of the side pin 3 from the first locking groove 11 to the second locking groove 12 is the same as the length of the limiting groove 13, which will not hinder the rotation of the lock core 2.
[0046] The blade reset member 5 is a blade reset spring. A receiving chamber 28 for accommodating the blade reset spring is provided in the lock core 2. A hook 43 extends from the blade 4. One end of the blade reset spring is sleeved on the hook 43, and the other end contacts the bottom of the receiving chamber 28, which not only ensures good stability when the blade 4 is reset, but also facilitates the installation of the blade reset spring. The side pin reset member 6 is a side pin reset spring. Two groups of side pin reset springs are provided and are respectively located at the two ends of the side pin 3. A receiving groove 29 for accommodating the side pin reset spring is provided on the lock core 2. Lugs 31 extend from the two ends of the side pin 3. The two ends of the side pin reset spring contact the corresponding lugs 31 and the bottom of the receiving groove 29 respectively. The two side pin reset springs can ensure the stability of the side pin 3 when it slides and does not deviate. At the same time, the cooperation between the lugs 31 and the receiving groove 29 makes the installation of the side pin reset spring convenient and stable.
