Technical Field

[0001] This utility model relates to the field of combination lock technology, and in particular to a multifunctional combination lock. Background Technology

[0002] Currently, locks on the market are typically electronic locks, key locks, and combination locks. Key locks unlock by rotating the lock cylinder using a key, while combination locks unlock by extending or retracting a combination lock shaft using the correct combination. However, there are currently no locks that combine key locks and combination locks. Utility Model Content

[0003] The purpose of this invention is to solve the technical problem of locks that do not combine key locks and combination locks in the background art. To this end, a multifunctional combination lock is provided.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A multi-functional combination lock includes a housing and a bottom cover connected together. A push button is slidably installed on the housing. A lock cylinder is sleeved on the push button. A circular boss is eccentrically provided on the lock cylinder.

[0006] A sliding plate is slidably mounted on the bottom cover. The sliding plate is connected to a locking rod, which passes through the housing and extends to the outside of the housing.

[0007] The circular boss of the lock cylinder is inserted into the opening groove of the slide plate.

[0008] The following is a further technical solution of this utility model: the housing is equipped with a password wheel assembly, the password wheel assembly includes a password shaft that is elastically telescopically arranged, and one end of the password shaft abuts against a push button.

[0009] The following is a further defined technical solution of this utility model: a circular cap is provided at one end of the locking rod, and the circular cap is locked in the groove of the sliding plate.

[0010] Compared with the prior art, the present invention has the following technical effects:

[0011] This invention utilizes an eccentrically positioned circular boss on the lock cylinder. When the key rotates the lock cylinder, it causes the sliding plate to slide, which in turn causes the lock rod to extend or retract. By incorporating a push button and a combination wheel assembly, when the combination is correct, the combination shaft in the combination wheel assembly can be pushed by the push button. When the push button and the lock cylinder slide together, the circular boss on the lock cylinder causes the sliding plate to slide as well, which in turn causes the lock rod to extend or retract, thereby achieving the unlocking and locking effects of the key and combination.

[0021] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0023] like Figure 1-6 As shown, a multi-functional combination lock is provided, mainly composed of a housing 1, a locking rod 2, a sliding plate 3, a lock cylinder 4, a push button 5, a combination shaft 6, a spring 7, and other components. The lock has two unlocking and locking methods: 1. When the combination is correct, it can be unlocked or locked by pushing the push button 5; 2. It can be unlocked or locked using a key.

[0024] A push button 5 is slidably mounted on the housing 1, and a lock cylinder 4 is sleeved on the push button 5. The lock cylinder 4 has an eccentrically positioned circular boss 401. A sliding plate 3 is slidably mounted on the bottom cover, and a locking rod 2 is connected to the sliding plate 3. The locking rod 2 passes through the housing 1 and extends to the outside of the housing 1. The circular boss 401 of the lock cylinder 4 is inserted into the opening groove 302 of the sliding plate 3. A combination wheel assembly is installed on the housing 1. The combination wheel assembly includes a combination shaft 6 that is elastically telescopically set, and one end of the combination shaft 6 abuts against the push button 5.

[0025] like Figure 4 and 6 As shown, the locking method of push button 5 is as follows: When the password is correct, push button 5 can be pushed to lock. Specifically: Pushing push button 5 forward extends lock rod 2, achieving the locked state; pushing push button 5 backward retracts lock rod 2, achieving the unlocked state.

[0026] One end of the locking rod 2 is designed with a circular cap 202 that fits into the groove 301 of the slide plate 3. The main body of the locking rod 201 passes through the hole 101 of the housing 1. When the slide plate 3 slides, the main body of the locking rod 201 extends and retracts with the slide plate 3. When the password is correct, pushing the push button 5 causes the push button baffle 501 to push the password shaft 6, compressing the spring 7 and sliding it to one side. The push button 5 and the lock cylinder 4 slide together. The lock cylinder 4 is designed with a circular boss 401, which is inserted into the opening groove 302 of the slide plate 3 during assembly. Therefore, when the push button 5 is pushed and the push button 5 and the lock cylinder 4 slide together, the circular boss 401 of the lock cylinder 4 drives the slide plate 3 to slide together, so that the locking rod 2 can extend and retract, achieving the unlocking and locking effects.

[0027] like Figure 3 and 4As shown, the key locking method is as follows: Whether the password is correct or incorrect, turning the key will rotate the lock cylinder 4 to lock the lock. Specifically: turning the key 90 degrees clockwise retracts the lock bar 2, achieving the unlocked state; turning the key 90 degrees counterclockwise extends the lock bar 2, achieving the locked state.

[0028] The position of the circular boss 401 of the lock cylinder 4 changes (due to the eccentric setting of the circular boss 401). The circular boss 401 is connected to the opening groove 302 of the slide plate 3, which drives the slide plate 3 to slide. The slide plate 3 drives the locking rod 2 to extend and retract.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model using the disclosed methods and techniques, or modify it into equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of this utility model. Therefore, all equivalent changes made based on the shape, structure, and principle of this utility model without departing from its technical solution should be covered within the protection scope of this utility model.
