Q:Yue Ma lock a few product level? How about the empty lock cylinder: Yue Ma lock, the traditional ball lock up and down the bullet holes on the hole interlocking lock principle, instead of the shrapnel from the rotation angle to transform, by a monolithic key to lock the way to change the traditional ball were locked method , To avoid the dislocation and liquid clogging phenomenon. If you want to open the lock, you must put all the keypad of the shrapnel at once in the lock groove, in a zigzag keyway, the key can move inward, in the field of technical open to deal with great Breakthrough, the bilateral set of mechanical keys, keyway lock is the mechanical transmission to prevent the only device to twist. Cylinders also add keyless twist settings, non-lock key into the keyhole can be arbitrarily twisted 360 degrees, but the lock is still not open. In today's world of anti-theft lock, the lock structure from the anti-technology to open, anti-destructive tools, process production process, the cost level and consider the interests of investors to evaluate multiple angles, Yue Ma lock is a leading trend, Replace the traditional structure of the new ball lock products.

Q:Security door in the A-level lock, B-lock, C-level lock What is the difference?: A-level lock: Currently on the market A-level anti-theft lock key is a word key and cross key. A-level cylinder internal structure is very simple, limited to the changes in the ball, the ball slot less shallow. Anti-technical open time 1 minute, the opening rate is extremely high. The ball structure is a single row of balls or a cross lock.

Q:Which locks are safer: Check the A and B by checking the key. If it is a single row of marbles, security door installation is likely to be A-level lock cylinder. If you feel unsafe, you can consider replacing the ultra-B-level cylinder, to improve the overall anti-theft security features.

Q:There is a bike lock can not turn after the direction of this lock is what the name of the lock: (Also known as the steering column) and the direction of the shaft tube (also known as the leading tube), deflection in the side of the fixed angle, the direction of the car shaft, So that it can not be free to turn, not to the front.

Q:What is the way to open the horse lock?: Set the law; with the first do not lock the other. Be careful not to top the spring. Hand to move around. Do not die. Fork into the tool about the depth of the type. Do not stop at the same time do not stop. Replace the tool in turn until the 5 tools are finished. If not open. Use two tools to overlap. Insert the lock body up and down around the depth. At the same time, two tools are gathered. In order to achieve the change of tooth position 5 tools in turn from the stack reverse, can achieve the maximum tooth changes. "Do not stop at all. To sway left and right until you open. My tool is made of repair gears. Because it is hard enough.

Q:Rotary safe password lock has a password: (30) at the end of the mark line that is stopped, then the password lock is completed after the completion of three groups of digital sign, the password lock do not move, and then the key into the keyhole within the right unlock, Twist the handle outside to open the door.

Q:The role of off-road truck differential lock?: Locked differential (mechanical lock, electric lock, pneumatic lock) In order to ensure the vehicle in the complex off-road conditions under the driving performance, through a certain mechanical structure of the differential lock, to achieve the simultaneous rotation of the two axles. Through the planetary gear set analysis, is the planetary gear set of the transmission mechanism to lock, to ensure that between the planet carrier and the sun wheel, and the transmission between the two sun wheels are 1: 1. You can lock the sun wheel and planetary planes, you can put the planet carrier and planetary gear lock, you can also lock the two sun wheels. Locked differential, in the absence of locking, the drive characteristics and open differential exactly the same, in the case of locking, the transmission ratio is fixed to 1: 1. The advantage of this differential is self-evident, providing the greatest driving force on off-road pavement. The disadvantage is that the steering of the vehicle is extremely difficult when the differential is locked; there is a possibility that the bicycle will be 100% , The axle will be deformed or broken because of excessive torque; the vehicle in the process of steering, the two half of the bearing by the opposite torque, if the adhesion of both sides of the tire are large, will cut the axle. In addition, this differential, in the vehicle during the implementation of the lock action will produce relatively large noise. The locking differential has all the structure and characteristics of the open differential. In the case of unlocking, the application range is the same as that of the open differential. In the case of locking, it is only suitable for low speed travel Pavement, can not travel on the pavement, otherwise it will lead to vehicle damage and steering out of control. This type of differential is represented by ARB's pneumatic locking product and Eaton's electric locking product.
