Description

Technical Field

[0001] The present application relates to a lock, and in particular to a disc brake lock. Background Art

[0002] Disc brake locks are generally used on bicycles or motorcycles to lock the wheels, brakes, disc brakes, etc. of bicycles or motorcycles.

[0003] At present, disc brake locks on the market generally include a shell, a lock core and a locking rod. The shell has a lock slot and a lock hole located on the bottom wall of the lock slot and connected to the lock slot. The lock slot is used to cooperate with the disc brake disc. The lock slot has an inlet and outlet for the disc brake disc to enter and exit horizontally. The inlet and outlet are located on the side wall of the shell. The lock core is movably arranged on the shell so that the lock core can rotate relative to the shell and move up and down. The locking rod is arranged on the lock core and is coaxially arranged with the lock core. The locking rod and the lock hole are detachably connected. The disc brake disc is locked by inserting the lock slot into the disc brake disc and connecting the locking rod and the lock hole.

[0004] In actual applications, since the lock slot cooperates with the disc brake disc, the lateral dimension of the lock slot must be large enough. In this case, the coaxially arranged lock core and lock rod must be arranged on the side of the shell having the above-mentioned inlet and outlet, so that the lock slot can have a sufficiently large lateral dimension. However, due to the large volume of the lock core, this structural arrangement makes the lateral dimension of the shell larger, resulting in a larger overall volume of the disc brake lock and occupying more space.

[0051] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0052] See also Figure 1-Figure 7 , shows a disc brake lock of a preferred embodiment of the utility model, comprising:

[0053] The housing 1 has a first guide groove 121, a locking groove 111, an inlet and outlet 112, a locking hole 113 and a first avoidance hole 114. The first guide groove 121 is located above the locking groove 111. The first guide groove 121 passes through the top wall of the housing 1. The locking groove 111 is used to cooperate with the disc brake disc. The inlet and outlet 112 is located on one side of the housing 1 and is connected to the locking groove 111. The inlet and outlet 112 is used for the disc brake disc to enter and exit the locking groove 111 horizontally. The locking hole 113 is provided on the bottom wall of the locking groove 111 and is located On the side close to the inlet and outlet 112, the lock hole 113 is connected to the lock groove 111, and the first avoidance hole 114 is provided on the bottom wall of the first guide groove 121 and is located directly above the lock hole 113. The first avoidance hole 114 is connected to the first guide groove 121 and the lock groove 111. The central axis of the first avoidance hole 114 and the central axis of the first guide groove 121 are arranged spaced apart in the transverse direction of the housing 1, and the central axis of the first avoidance hole 114 is closer to the inlet and outlet 112 than the central axis of the first guide groove 121.

[0054] The lock core 2 is movably disposed on the first guide groove 121. The lock core 2 has a locked state in which it is retracted into the first guide groove 121 and an unlocked state in which it is at least partially extended out of the first guide groove 121. The lock core 2 is movable to switch between the locked state and the unlocked state.

[0055] The locking rod 3 is connected to the lock core 2 . The locking rod 3 is movably arranged in the first avoidance hole 114 . The locking rod 3 can be matched with or disengaged from the lock hole 113 as the lock core 2 moves.

[0056] The disc brake lock of the present invention can make the lock rod 3 deviate from the lateral center of the lock core 2 because the central axis of the first avoidance hole 114 and the central axis of the first guide groove 121 are arranged at intervals along the lateral direction of the shell 1. At the same time, because the central axis of the first avoidance hole 114 is closer to the inlet 112 than the central axis of the first guide groove 121, the lock core 2 can be made closer to the lateral center of the shell 1 under the premise that the lateral dimension of the lock groove 111 is sufficient to cooperate with the disc brake disc, which not only improves the lateral space utilization rate of the shell 1, but also avoids the lateral dimension of the shell 1 being larger due to the lock core 2 being arranged close to one side of the shell 1, thereby reducing the lateral dimension of the shell 1, making the overall volume of the disc brake lock smaller and occupying less space.

[0057] See also Figure 6-Figure 7 In one embodiment, the housing 1 further has a limiting hole 122, which is disposed on the side wall of the first guide groove 121, and the limiting hole 122 is connected to the first guide groove 121;

[0058] A toggle portion 21 is provided at the bottom of the lock core 2;

[0059] The disc brake lock also includes:

[0060] The first limiting member 4 is disposed in the first guide groove 121 so as to be laterally movable. The first end of the first limiting member 4 has a stop state that matches with the limiting hole 122 and an avoidance state that is disengaged from the limiting hole 122. The first limiting member 4 has a positioning groove 41. The positioning groove 41 matches with the toggle portion 21 so that the first limiting member 4 can move with the rotation of the lock cylinder 2. The first limiting member 4 moves and switches from the stop state to the avoidance state.

[0061] A first elastic member 5, the first elastic member 5 is disposed between the second end of the first limiting member 4 and the side wall of the first guide groove 121, and the first elastic member 5 is used to drive the first end of the first limiting member 4 to switch from the avoidance state to the stop state, ensuring that the first end of the first limiting member 4 can be reliably matched with the limiting hole 122;

[0062] The second elastic member 6 is disposed between the bottom wall of the first guide groove 121 and the bottom of the lock core 2 , or the second elastic member 6 is disposed between the bottom wall of the first guide groove 121 and the lock rod 3 , and the second elastic member 6 is used to drive the lock core 2 to extend out of the first guide groove 121 . In this way, the first end of the first limiting member 4 and the limiting hole 122 can be used to cooperate with each other to limit the lock core 2, restrict the lock core 2 from moving along the first guide groove 121, ensure that the lock rod 3 can reliably cooperate with the lock hole 113, and the locking reliability is high. In addition, when the lock core 2 is driven to rotate by the key, the toggle portion 21 follows the lock core 2 to rotate and cooperate with the positioning groove 41 to toggle the first limiting member 4 to move laterally, so that the first end of the first limiting member 4 and the limiting hole 122 are disengaged, the limitation on the lock core 2 is released, and the lock core 2 can move along the first guide groove 121. At the same time, the second elastic member 6 is reset to push the lock core 2 away from the bottom wall of the first guide groove 121, so that the lock core 2 automatically switches from the locked state to the unlocked state, and the unlocking is smoother and more convenient.

[0063] In one embodiment, the first elastic member 5 and the second elastic member 6 are both springs. Of course, in other embodiments, the first elastic member 5 and the second elastic member 6 are both elastic structures such as spring sheets.

[0064] See also Figure 6 In one embodiment, the housing 1 further has a limiting groove 123, which is disposed on the side wall of the first guide groove 121, and the limiting groove 123 is connected to the first guide groove 121;

[0065] The disc brake lock also includes:

[0066] The second limit member 7 is arranged on the lock core 2 or the lock rod 3. When the lock core 2 is in the unlocked state, the second limit member 7 cooperates with the limit groove 123. In this way, the moving stroke of the lock core 2 can be limited to avoid the lock core 2 moving stroke being too long and reducing the lock opening and closing efficiency. At the same time, the lock core 2 can be limited from being separated from the first guide groove 121 to prevent the lock core 2 from being separated from the housing 1.

[0067] See also Figure 2 and Figure 7 In one embodiment, a connecting head 8 is provided at one end of the lock rod 3 close to the lock core 2, and the connecting head 8 is provided with a second guide groove 81. The second guide groove 81 passes through the connecting head 8 on both sides. The second guide groove 81 and the first limit member 4 can be slidably matched to position the first limit member 4, so that the first limit member 4 moves on the set path, ensuring that the first limit member 4 can reliably match or disengage with the limiting hole 122, and the structural reliability is higher. At the same time, the first limit member 4 can also be guided to move, so that the first limit member 4 moves more smoothly, which is beneficial to improving the efficiency of opening and closing the lock.

[0068] See also Figure 1-Figure 7 In one embodiment, the housing 1 comprises:

[0069] The housing 11 has a locking groove 111, an inlet and outlet 112, a locking hole 113, a first avoidance hole 114 and a first installation groove 115, and the first installation groove 115 passes through the top wall of the housing 11;

[0070] The reverse sleeve 12 is inserted into the first installation groove 115, and the reverse sleeve 12 has a first guide groove 121, a limiting hole 122 and a limiting groove 123. Since the housing 1 is a split structure consisting of the outer shell 11 and the reverse sleeve 12, the outer shell 11 and the reverse sleeve 12 can be processed separately, which can reduce the processing difficulty and help reduce costs. At the same time, during assembly, the lock core 2 can be first installed on the reverse sleeve 12, and then the assembly formed by the reverse sleeve 12 and the lock core 2 can be installed on the outer shell 11, which can reduce the assembly difficulty of the lock core 2 and make the assembly more convenient.

[0071] See also Figure 1-Figure 7 In one embodiment, the housing 1 further comprises:

[0072] The lock housing 13 is movably arranged on the first guide groove 121, and the lock housing 13 has a second mounting groove and a second avoidance hole, the second mounting groove passes through the bottom wall of the lock housing 13, the second mounting groove accommodates the lock core 2, the first position limiting member 4 and at least part of the connector 8, and the second avoidance hole is arranged on the side wall of the lock housing 13, the second avoidance hole is connected to the second mounting groove, and the second avoidance hole is movably provided for the first position limiting member 4. In this way, the lock housing 13 can be used to realize the assembly of the lock core 2, the first position limiting member 4 and at least part of the connector 8 together to form a modular structure, making the assembly more convenient.

[0073] In one embodiment, the lock housing 13 further has a first connecting hole, which is disposed on a side wall of the lock housing 13 and communicates with the second mounting groove;

[0074] The connector 8 has a second connecting hole;

[0075] The first end of the second limiting member 7 is provided with the first connection hole and the second connection hole in sequence and is screwed with the second connection hole. The second end of the second limiting member 7 is located outside the lock housing 13, and the second end of the second limiting member 7 is matched with the limiting groove 123. In this way, the second limiting member 7 is used to connect the connector 8 and the lock housing 13, and then the lock rod 3 and the lock core 2 are connected together, so that the second limiting member 7 can be used to limit the movement stroke of the lock core 2 and connect the lock rod 3 and the lock core 2, achieving dual-purpose, eliminating the need to set up an additional connecting member to connect the lock core 2 and the lock rod 3, simplifying the structure, and further reducing the cost.

[0080] Specifically, in the process of normal locking by driving the lock cylinder 2 with the key, the lock shell 13 is half pressed into the reverse sleeve 12, and the detector 10 detects the position information of the magnet 9 for the first time, and then releases the lock shell 13 to make the lock shell 13 bounce up, and then presses the lock shell 13 completely into the reverse sleeve 12. At this time, the detector 10 detects the position information of the magnet 9 for the second time, and the system determines that it is a normal locking that does not require the alarm 20 to work, and the alarm 20 is turned off. At this time, the disc brake lock will not trigger an alarm by being tapped or swung from the outside; after a period of normal locking, the detector 10 detects that the position of the magnet 9 has not changed, and the alarm 20 is turned on. At this time, the disc brake lock will trigger an alarm by being tapped or swung from the outside.
