Problems solved by technology

The lock has two lockways on the left and right, which effectively increases the difficulty for the thief to open illegally. However, the two lockways on the left and right diverge from each other and can only be matched with a double-body chain link soft key. It is not easy to align the key with the key hole, the unlocking speed is relatively slow, and the soft key of the chain link is easy to break after long-term use, and the service life is relatively low; in addition, the lock cylinder structure of the lock is relatively complicated, and there are relatively many parts. The assembly process is relatively low and the assembly accuracy requirements are high, which affects assembly efficiency

Embodiment 1

[0041] Such as Figure 1-Figure 4 As shown, the lockset with double lockways provided by this embodiment includes a lock sleeve 100, a lock cylinder 200 inserted in the lock sleeve 100, and a key 300 matched with the lock cylinder 200. Of course, the lockset with double lockways in this embodiment It also includes parts such as the lock housing and the dead bolt of the conventional tumbler lock, which is not the focus of this embodiment, and will not be described in detail here.

[0042] The lock sleeve 100 is fixedly connected to the housing of the lock, and the lock core 200 can be rotated relative to the lock sleeve 100 under the drive of the key 300, and then drives the lock bolt of the lock to rotate to realize locking or unlocking. It should be noted that, in this embodiment, the locked state, that is, the state in which the key 300 has not been inserted into the lock cylinder 200 is taken as the initial state of the lock.

[0043] The lock cylinder 200 includes a core ...

Embodiment 2

[0051] Such as Figure 5 with Image 6 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the core body 210 is also provided with a third bullet hole 225 , and the specific location and quantity of the third bullet hole 225 can be determined according to actual needs.

[0052] exist Figure 5 Among them, there are more than one third bullet holes 225 (only one third bullet hole 225 is shown in the figure), and when they are all located on the same side of the core body 210, each third bullet hole 225 communicates with the same lockway respectively. Image 6 Among them, there are more than two third bullet holes 225, and they are respectively located on both sides of the core body 210 (only two third bullet holes 225 are shown in the figure), and the third bullet holes 225 on the same side communicate with a lockway respectively. . Of course, the lock sleeve 100 is also provided with a fourth bullet hole 120 matched with the third b...

Abstract

The invention provides a lock provided with two lock channels. The lock provided with the two lock channels comprises a lock sleeve, a lock cylinder and a key. The lock cylinder comprises a cylinder body, a first cavity and a second cavity. A first channel is formed in the first cavity. A second channel is formed in the second cavity. A third channel and a fourth channel are formed in the two sides of the cylinder body correspondingly. The third channel and the fourth channel are staggered and communicate with each other. The first lock channel is formed by the first channel and the third channel jointly. The second lock channel is formed by the second channel and the fourth channel jointly. The key comprises a handheld part and a hard body part fixedly connected with the handheld part. The two lock channels are staggered and communicate with each other so that the difficulty of illegal unlocking by a burglar can be effectively increased; by adoption of the hard body part, the key can be aligned to a key hole relatively rapidly, the unlocking speed is relatively high, using is more convenient, and the service life is relatively long; and in addition, by adoption of the three-layer lock cylinder structure, the assembling efficiency is relatively high.

Description

technical field [0001] The invention relates to a lock, in particular to a lock with double lockways. Background technique [0002] There are many types of locks on the market, among which pin locks are the most common. Existing pin locks usually have a lock channel and a pin group that matches the lock channel. There is usually only one lock channel and pin group. Some more complicated pin locks will be set There are two groups of marbles to reduce the mutual opening rate of the lock, but there is only one lockway, which is easily opened illegally by the thief using a special tool (such as a lock gun, etc.). [0003] The Chinese invention patent application with the publication number CN102605997A discloses a double-body chain soft key lockset, which includes a lock body and a matching chain link soft key. There are an outer lock cylinder, a middle lock cylinder and an inner lock cylinder in sequence. The outer side of the outer lock cylinder is slidably connected with the...
