Description

Technical Field

[0001] The utility model relates to the technical field of luggage locks, in particular to a luggage lock with a swing arm transmission. Background Art

[0002] With the need of people to travel for work, tourism, business trips, etc., all kinds of bags have occupied an increasingly important position in people's lives. People often put some valuables and materials into bags for easy carrying. Therefore, the safety and anti-theft of bags are increasingly valued by people, and bag locks have become an indispensable part of bags.

[0003] In the prior art, the luggage lock includes a locking assembly, which includes a first lock hook and a second lock hook respectively installed on the two opening and closing sides of the luggage, and the two lock hooks are locked with each other. The luggage lock also includes an operating member (which can be replaced by a push button, a knob, etc.), a locking mechanism and a transmission member. The locking mechanism is a password lock, a key lock cylinder or NFC. The restriction of the operating member can only be released after the password of the locking mechanism is unlocked or the correct key is inserted and turned or the near-field electric control induction is triggered. The operating member drives the first lock hook to rotate or slide through the transmission member, and releases the lock with the second lock hook to achieve unlocking.

[0004] For example, a password lock disclosed in a Chinese patent document with publication number CN205012764U includes a central lock, a first side lock and a second side lock, wherein the first side lock is arranged at both ends of the central lock, and the first side lock and the second side lock are controlled by a rotating block and a steel wire rope, and the central lock controls the opening and closing of the first side lock and the second side lock through a central control transmission mechanism therein, wherein the central lock, the first lock buckle of the first side lock, and the second lock buckle of the second side lock are fixed to the frame of one opening and closing side of the box, and the first lock hook of the first side lock and the second lock hook of the second side lock are fixed to the frame of the other opening and closing side of the box. The opening and closing of multiple side locks is controlled by the central control transmission mechanism, making the password lock safer, and since the central control transmission mechanism has fewer transmission components and a simple transmission relationship, the stability of the password lock transmission is more reliable and the assembly of the password lock is convenient.

[0005] Another example is a central control multi-linkage luggage lock disclosed in a Chinese patent document with the publication number CN221169095U, which includes a central control lock and more than two side locks provided on the same side outside the central control lock. The central control lock includes a lock shell, a locking mechanism and a transmission member. The locking mechanism is installed in the lock shell, and the transmission member is installed in the lock shell and restricted by the locking mechanism. After the correct instruction is input into the locking mechanism, the transmission member can be operated to move. Each side lock includes a lock body, a lock buckle and a lock hook. The lock buckle is movably installed on the lock body for buckling the lock hook. The transmission member and the lock buckles of different side locks are connected in series via a steel cable, so that when the transmission member moves, it can drive the lock buckles of each side lock to move via the steel cable, and then disengage from the corresponding lock hooks to unlock. Since more than two mutually connected side locks are provided on the same side of the central control lock, two or more side locks can be correspondingly used to lock the same side of the luggage, or the purpose of locking more sides of the luggage can be achieved.

[0006] In the prior art, the steel cable is pulled by the linear sliding of the transmission member. In the way of linear pulling, the moving distance of the transmission member is equal to the moving distance of the steel cable, and a relatively large moving distance of the transmission member is required to drive the steel cable for a sufficient stroke.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0032] A swing-arm drive luggage lock in this embodiment, as Figures 1 to 4 shown, includes a lock case 1, an upper locking mechanism 2 and a transmission member 3. The upper locking mechanism 2 is installed in the lock case 1. The transmission member 3 is movably installed in the lock case 1 and is restricted by the upper locking mechanism 2. After the upper locking mechanism 2 inputs a correct instruction, the transmission member 3 can be operated to move. The upper locking mechanism 2 includes a password component 21 and a key lock core 22. Inputting the correct password or inserting the correct key serves as the correct instruction. The transmission member 3 is slidably installed in the lock case 1. The transmission member 3 is also connected with a push rod 4 extending outside the lock case 1 for external operation in the unlocked state. The transmission member 3 can be changed to a rotary type, and the push rod 4 can be changed to a knob / button. The above can all adopt the structures of the prior art and will not be elaborated here. The main improvement lies in:

[0033] It further includes a steel rope 5, a swing rod 6, a traction seat 7 and a support seat 8. The support seat 8 is fixed in the lock case 1. The traction seat 7 is slidably installed on the support seat 8. One end of the steel rope 5 is connected to the traction seat 7 and extends outside the lock case 1. The middle of the swing rod 6 is hinged to the support seat 8 so that the swing rod 6 can swing with its middle as the fulcrum. One end of the swing rod 6 is connected to the traction seat 7, and the other end of the swing rod 6 abuts against the transmission member 3. In the unlocked state, the transmission member 3 can push against the end of the swing rod 6 to cause it to swing and then pull the traction seat 7 and the steel rope 5. The support seat 8 is provided with an avoidance groove 81 for the swing rod 6 to move therein. In practice, a spring can be arranged in the lock case 1 to apply a force to the traction seat 7 or the swing rod 6 to keep it in the potential energy position for locking.

[0034] In this embodiment, the traction seat 7 is provided with a positioning groove 71 with an upward opening. The opposite side walls of the positioning groove 71 are recessed to form support grooves 72. The end of the swing rod 6 is provided with a positioning post 61, and the positioning post 61 is embedded in the support groove 72. When the swing rod 6 swings, the end of the swing rod 6 makes a circular arc motion. Therefore, the positioning post 61 will move up and down in the support groove 72.

[0035] In this embodiment, the steel rope 5 includes a rope socket 51 and a rope core 52 movably passing through the rope socket 51. A limiting post 53 is provided at the end of the rope core 52, and the limiting post 53 is fixed to the traction seat 7. The traction seat 7 is provided with an embedding groove 73, and the limiting post 53 is embedded in the embedding groove 73.

[0036] In this embodiment, the length from the hinge point of the swing rod 6 to the end of its mating transmission member 3 is less than the length from the hinge point to the end where it is connected to the traction seat 7, that is Figure 4 the A section of the swing rod 6 shown in is shorter than the B section. According to the lever principle, the stroke of the traction seat 7 can be increased.

[0037] Specifically, the swing rod 6 is flat, and the middle hinge part and both ends are cylindrical.

[0038] Specifically, a relief hole 11 for the steel rope 5 to pass through is opened at the end of the lock case 1 in the length direction.
