Description

Technical Field

[0001] The utility model relates to the technical field of luggage locks, and particularly relates to a lock seat assembly with traction transmission. Background Art

[0002] With the needs of people's travel for work, tourism, business trips, etc., various types of luggage have occupied an increasingly important position in people's lives. People often put some valuables and documents into the luggage for easy carrying. Therefore, the safety and anti-theft of luggage have attracted more and more attention from people, and luggage locks have become an indispensable part of luggage.

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

[0004] For example, the Chinese patent document with the publication number of CN221169095U discloses a central control multi-linkage luggage lock, which includes a central control lock and two or more 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 buckle between different side locks are connected in series via a steel rope, so that when the transmission member moves, it can drive the lock buckles of each side lock to move via the steel rope, and then disengage from the corresponding lock hooks to unlock. Since two or more side locks connected in series 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.

[0005] For the side lock, it directly pulls the linkage block through a steel rope to control the lock hook to be in the unlocked or locked posture. That is, the moving distance of the steel rope is equal to the sliding distance of the linkage block. To ensure that the linkage block moves a sufficient distance to ensure that the lock hook moves to the unlocked state, the steel rope must also move a sufficient distance, and the operating member on the central control lock needs to be manually operated a sufficient large distance. For example, the push button needs to slide a sufficient large distance, which brings a bad experience to consumers. Summary of the Invention

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0035] A lock seat assembly with traction drive in this embodiment, asFigures 1 to 5 As shown, it includes a side lock shell 1, a linkage rod 2, a steel rope 3, a lock hook 4 and a lock buckle 5. The side lock shell 1 is provided with two lock holes 11 arranged separately. The two lock buckles 5 are movably installed in the side lock shell 1 and are located at the corresponding lock holes 11. The same lock hook 4 is provided with two hook portions 41 respectively matching with different lock buckles 5. The hook portion 41 of the lock hook 4 can be inserted into the lock hole 11 and matched with the lock buckle 5 for locking.

[0036] The linkage rod 2 is slidably mounted in the side lock housing 1, and a swing rod 6 is also provided in the side lock housing 1. The middle part of the swing rod 6 is rotatably mounted in the side lock housing 1. The steel rope 3 penetrates into the side lock housing 1 to connect one end of the swing rod 6. The other end of the swing rod 6 is movably connected to the linkage rod 2. The length from the fulcrum of the swing rod 6 to the end of the steel rope 3 that matches it is less than the length from the fulcrum to the end of the linkage rod 2 that matches it. When in use, the steel rope 3 pulls the swing rod 6 to rotate, thereby driving the linkage rod 2 to slide. According to the principle of lever, the sliding distance of the linkage rod 2 is greater than the moving distance of the steel rope 3, which increases the stroke of the linkage rod 2. A small displacement of the steel rope 3 can drive a sufficient unlocking displacement of the linkage rod 2.

[0037] In this embodiment, the steel rope 3 includes a rope loop 31 and a rope core 32 that movably passes through the rope loop 31, a limiting cylinder 33 is provided at the end of the rope core 32, and the swing rod 6 is provided with a first limiting column 61, which is inserted into the limiting cylinder 33. The swing rod 6 is also provided with a second limiting column 62, and the linkage rod 2 is provided with a long hole 21, and the second limiting column 62 is movably inserted into the long hole 21.

[0038] In this embodiment, a first spring (not shown in the figure) is provided in the side lock housing 1 to apply force to the linkage rod 2, so that the swing rod 6 and the linkage rod 2 tend to be kept in the locked position. In practice, it can be changed to: the first spring is a torsion spring that applies force to the swing rod 6, which can also keep the linkage rod 2 and the swing rod 6 in the locked position.

[0039] In this embodiment, an unlocking block 7 is slidably provided in the side lock housing 1, and its sliding direction is the same as that of the linkage rod 2. The linkage rod 2 drives the lock buckle 5 to unlock via the unlocking block 7. The lock buckle 5 is rotatably installed on the side lock housing 1. A second spring is provided in the side lock housing 1 to apply force to the lock buckle 5 so that the lock buckle 5 maintains the unlocking tendency. The side lock housing 1 is provided with a third spring to apply force to the unlocking block 7 so that the unlocking block 7 maintains the reset locking tendency. The unlocking block 7 is provided with an unlocking groove 71. In the locked state, the unlocking groove 71 is staggered with the lock buckle 5; in the unlocked state, the linkage rod 2 overcomes the force of the third spring and moves the unlocking block 7 so that the lock buckle 5 is aligned with the unlocking groove 71, thereby leaving space for the lock buckle 5 to rotate, and the lock buckle 5 rotates and partially fits into the unlocking groove 71.

[0040] In this embodiment, the linkage rod 2 is provided with a guide groove 22 , and the unlocking block 7 is provided with a guide protrusion 72 , and the guide protrusion 72 is embedded in the guide groove 22 in a directionally slidable manner.

[0041] In this embodiment, the side lock housing 1 is provided with an elastic column 8 that applies an outward thrust to the lock hook 4. The elastic column 8 is slidably mounted in the side lock housing 1, and a fourth spring that applies a force to the elastic column 8 is provided inside the side lock housing 1. After unlocking, the elastic column 8 ejects the lock hook 4.
