Description

Padlock

Technical field

The utility model relates to the lock that uses in a kind of daily life, particularly a kind of follow-on padlock.

Background technology

In daily life, people will use various locks to come article are taken care of.Normally used padlock is made of lock body, lock bridge, return spring, dead bolt, lock tongue slot, latch bolt spring, straight-line groove key etc., this padlock makes trouble, also damage lock tongue slot, latch bolt spring during use easily, and because padlock adopts the straight-line groove key mostly, so security performance is lower, the mutual opening rate of padlock is higher.Chinese patent discloses a kind of padlock, and its number of patent application is 89221592.5, and this padlock replaces dead bolt with steel ball, and more convenient in use, but this padlock still adopts the straight-line groove key, and friction is bigger in use, the life-span of lock is shorter, and the mutual opening rate of lock is not improved yet; This problem all needs further solution.

Summary of the invention

The purpose of this utility model is in order to solve the deficiency that above-mentioned padlock exists, and provides a kind of security performance good, the novel padlock of long service life.

The utility model is achieved through the following technical solutions: this padlock, mainly contain lock body, lock bridge, lock core, lock core cover, key, steel ball, locating hole, and curved groove is wherein arranged on the key; Lock core is divided into lock core front end and lock core rear end, the lock core rear end radially have a slotted hole, the pellet shot from a slingshot that is complementary with it is housed, the equal diameters of the length of pellet shot from a slingshot and lock core rear end in the slotted hole; Columniform ridge is arranged on the pellet shot from a slingshot; Ridge and shaped form groove on the key are complementary; Lock core is placed on the lock core cover, and lock core puts and has the hole and match with pellet shot from a slingshot.Because groove on the key is a shaped form, this key is also few on the market, so the security performance of lock is also relatively good, mutual opening rate is also lower.In use, when key inserted, the columniform ridge on the pellet shot from a slingshot was placed on curved groove on the key, and the position of pellet shot from a slingshot is controlled by groove on the key like this, this moment, pellet shot from a slingshot just became a cylinder with the lock core rear end, so just can rotary locking cylinder.

The utility model can also be made snakelike groove with curved groove on the key, and when key inserted lock core like this, friction was less, and the profile of key is also elegant in appearance.

Padlock provided by the utility model can also be further perfect, and the slotted hole that radially has of lock core rear end is done circular slotted hole, and when pellet shot from a slingshot moved therein like this, friction was littler, and is more flexible.

Padlock provided by the utility model, owing to adopted the shaped form groove, the good looking appearance of key is generous, and security performance is good, greatly reduces the mutual opening rate of padlock; Flexible when simultaneously this lock uses, friction is less, long service life.

Description of drawings

Lock body 1, lock bridge 2, lock core 3, lock core front end 3-1, lock core rear end 3-2, lock core cover 4, key 5, groove 5-1, steel ball 6, locating hole 7, pellet shot from a slingshot 8, ridge 8-1.

The specific embodiment

Embodiment 1: open two holes on lock body 1, put into lock bridge 2, lock bridge 2 two symmetrical inboards respectively have an arc notch, and the diameter of the size of breach and steel ball 6 adapts.On lock body 1, also have one with lock core cover 4, lock core cover 4 is fixed on the lock body 1 by locating hole 7; The inside of lock core cover 4 is placed with lock core 3, lock core 3 is divided into lock core front end 3-1 and lock core rear end 3-2, lock core rear end 3-2 radially has a circular slotted hole, in the circular slotted hole pellet shot from a slingshot 8 that is complementary with it is housed, the equal diameters of the length of pellet shot from a slingshot 8 and lock core rear end 3-2 has columniform ridge 8-1 on the pellet shot from a slingshot 8; Ridge 8-1 and snakelike groove 5-1 on the key are complementary; Lock core 3 is placed on lock core cover 4, has the hole on the lock core cover 4 and pellet shot from a slingshot 8 is complementary.During use, when lock was in locking-in state, lock core front end 3-1 was in the position of diameter maximum, promoted the arc notch that two steel balls 6 enter lock bridge 2 inboards, and lock core 3 can not overlap in 4 at lock core and rotate, and lock can not be opened firmly owing to the effect of pellet shot from a slingshot 8 this moment; When key 5 inserts lock core 3, ridge 8-1 on the pellet shot from a slingshot 8 and the groove 5-1 on the key 5 are complementary and closely cooperate, make the hole on pellet shot from a slingshot 8 and the lock core 3 fit in a cylinder, this moment, lock core 3 can be in lock core cover rotation, and when revolving when turning 90 degrees, lock core front end 3-1 is in the position of diameter minimum, the short side of lock bridge 2 can be extracted from lock like this, lock bridge 2 is drawn money on credit termination portion cannelure when touching steel ball 6, and by steel ball 6 card jails, lock bridge 2 can not deviate from from lock body 1 like this.
