Fig. 2 is the sectional structure chart of coded lock opening state of the present invention；
Fig. 3 is the sectional structure chart of coded lock setting cryptographic state of the present invention.
Specific implementation mode
With reference to the accompanying drawings and examples, the specific implementation mode of the present invention is described in further detail.Implement below
Example is not limited to the scope of the present invention for illustrating the present invention.
The anti-of the present invention rushes open coded lock, as shown in Figs. 1-3, including lock body 1, the first locking bar 2, combination locking mechanism 3, the
One locking bar 2 is arranged in lock body 1 and is used to lock, that is, needs the article locked to pass through the first locking bar 2 and be locked, combination locking mechanism
3 are located inside lock body 1, and combination locking mechanism 3 includes 4 digit wheels and sequentially passes through the second locking bar 4 of digit wheel, the first locking bar
2 are parallel to the setting of the second locking bar 4, and the lock body 1 between the first locking bar 2 and the second locking bar 4 is internally provided with transmission device 5, in this reality
It applies in example, transmission device 5 is several continuous compact arranged isometrical steel balls；The first end 51 of transmission device 5 and the first locking bar 2
Annular groove 21 match abutting, the second end 52 of transmission device 5 and the outer rim of the second locking bar 4 abut against.
Second locking bar, 4 first end have notch 41,5 second end 52 of transmission device can with the movement of the second locking bar 4 and to lack
41 inside of mouth is close and does not depart from notch 41；The second end 42 of second locking bar 4 is connected with eccentric handle 6, eccentric hand by axis pin
Handle 6 overcomes the elastic force of resetting spring 71 in rotation process, and the second locking bar 4 is driven to be subjected to displacement relative to lock body 1, eccentric hand
Handle 6 can also be replaced with other equivalent mechanisms, such as button or pull rod can realize the mechanism of above-mentioned movement purpose.
Lock body 1 is internally provided with locking bar anti-drop device, as shown in Fig. 2, locking bar anti-drop device includes being equipped with compressed spring 73
And the positioning pin 8 of cooperation；The second end of first locking bar 2 have with 8 matched annular groove 23 of positioning pin, when the first locking bar 2 is de-
After lock body device for ejecting, positioning pin 8 can be popped up and be supported into annular groove 23 by compressed spring 73, to prevent the first locking bar 2 completely
It is detached from lock body 1.
Lock body 1 is provided with locking bar device for ejecting, as shown in Fig. 2, locking bar device for ejecting includes spring 72, piston 10 and piston
Positioning pin 9.When first locking bar 2 is located inside locking bar device for ejecting, spring 72 is in compressive state, and the second locking bar 2 resists piston
10；After first locking bar 2 is detached from locking bar device for ejecting, the guide groove cooperation clamping piston 10 of piston positioning pin 9 and 10 surface of piston,
To prevent piston 10 from popping up lock body 1 by spring 72.
For coded lock in locking state, the notch 41 of the second locking bar 4 resists the steel ball of one end of transmission device 5, the first lock
The annular groove 21 of bar 2 resists the steel ball of the other end of transmission device 5, and the tip position of the notch 41 of the second locking bar 4 at this time
In position A, as shown in Figure 1；
In opening state, eccentric handle 6 rotates coded lock, overcomes the elastic force of resetting spring 71 and drives the second locking bar 4
Notch 41 be moved to tip to the direction for being detached from lock body 1 and be located at position B, as shown in Fig. 2, steel ball is to the direction of close notch 41
It is mobile so as to resist the steel ball of annular groove 21 far from annular groove 21, limit is not reconstructed to the first locking bar 2 until reaching
State so that the first locking bar 2 is detached from locking bar device for ejecting, that is, coded lock is opened；
When coded lock is in setting cryptographic state, eccentric handle 6 is rotated further, and overcomes the elastic force of resetting spring 71 and drive
The notch 41 of second locking bar 4 continues to be moved to tip to the direction for being detached from lock body 1 and be located at position C, as shown in figure 3, but steel at this time
The diameter of pearl is still above the maximum spacing between tip and lock body 1, to ensure that steel ball will not take off because of the movement of the second locking bar 4
It slides or falls off from the through-hole where transmission device 5；At this point, the second locking bar 4 and cipher locking device are without control planning, it is close
Code wheel can be stirred freely, you can to reset password.
First locking bar and the second locking bar of the invention form linkage mechanism, the locking point of multi-direction multiple location by transmission device
External force collision has been dissipated, coded lock has been reduced and is hit and lead to lock the probability flicked, to realize the anti-effect rushed open；It adopts
The second locking bar is driven with eccentric handle, replaces pulling with rotation, realizes laborsaving and section space-efficient effect；Transmission device uses
The isometrical steel ball continuously arranged, it is therefore intended that the contact area for minimizing the tip and transmission device of the second locking bar notch, with
Reduce abrasion and reduces the resistance in motion process.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
