Description

1258526 IX. Description of the invention: [Technical field to which the invention pertains] The present invention relates to a lock that can be replaced with a lock core, and provides a lock that can replace a lock core to prevent a defective departing employee from stealing property in the coin-operated device. . [Prior Art] Coin-operated electronic game machines, candy machines, vending machines, or toy machines have been widely used in people's daily lives, and people only need to cast hard

Into the aforementioned devices, you can play or obtain video games, candy, drinks or toys, and the maintenance personnel must periodically take out the coins in the device for the store or the manufacturer to know the profits. In order to prevent the thief from stealing the coins in the device, the housing of the device is provided with _ to protect the coins in the device, and the maintenance personnel need to: open the device to take out the coins in the device. :: Stores or manufacturers in order to save the opening [Therefore, short-term repair workers will be hired, so the turnover rate of maintenance personnel is high, and a certain - = no ^ (4) repair personnel can copy the lock before opening the job. ^ P 4Γ After leaving the company Stealing the money in the device, so that the store or the manufacturer is in a lot of money.豕和厂 Although the second, the mouth P knife shop or the manufacturer will replace the new locks will often make the store or = is a replacement replacement time. < σ, the cost of the eve of the eve and the content of the invention. The good resigned employee steals the inventor. In view of the fact that the existing locks can not make the financial disadvantages in the 1258526 device, the store or the factory avoids the aforementioned shortcomings, in order not to Increasing the cost, and then weighing: a lock that can be replaced with a lock, which has a casing and a core, so when the maintenance personnel leaves the company, the store or the barrier is only required to take out the lock case and replace the other lock. , for example, u's maintenance staff

The coin-operated device is opened with the original key, and the store _ merchant can secure the property inside, so the store or the manufacturer can reduce the cost and time of replacing the lock without replacing it for the purpose of invention. The technical means of the present invention is to provide a lock for replacing the lock core, which has a casing provided with a through hole, and a perforation communicating with the through hole at the outer circumference; a rotating rod a groove is arranged at one end surface, and the rotating rod is disposed at one end of the through hole of the outer casing, and one end of the rotating rod with a thread extends to the outside of the outer casing;

The cost of the coin-operated design is such that the lock core cannot be used to secure the lock. It is a lock core assembly for a casing which is disposed at the other end of the through hole of the casing and has a casing. There is a locking hole, the outer circumference of the casing is provided with a ball hole, the ball hole is also opposite to the perforation position of the casing, and a ball body is arranged in the ball hole; a locking bead seat has a rotating cylinder formed on one end surface thereof; An end face of the rotating cylinder body is formed with a block body which can be mutually abutted against the groove of the rotating rod, and the other end surface of the locking ball seat is formed with a protruding column; a positioning ring body is disposed at a position relative to the locking hole a bead hole is provided on the outer circumference of the positioning ring body and is provided with a ball groove at a position relative to the ball body; a lower locking bead seat is provided with a through hole, and the lower locking bead seat is adjacent to the through hole and is provided with a bead at a position relative to the bead hole In the groove, an array spring, a lower locking bead and a locking bead are sequentially arranged in the bead groove, and each of the upper locking bead and the lower locking bead extends from the bead groove to the 1258526 bead hole and the locking bead hole, and the lower locking bead is - the end will be pushed against the elastic, and the other end and the end of the locking bead will push each other, and the other end of the locking bead The inner surface of the locking hole of the body is pushed against each other, and the lower locking bead seat is disposed at the other end of the locking hole of the housing; the rotating cylinder of the locking bead seat sequentially penetrates the scorpion and the lower locking of the scorpion The through hole of the bead seat extends outward, and rotates the column ghost body and rotates; the groove of the dry stem is mutually offset. When the maintenance personnel leaves the company, the store owner or manufacturer can use the key to turn the locking bead seat. The locking bead seat will drive the positioning ring piece to rotate, so that the originally punctured ball located in the outer casing enters the heart of the positioning ring piece. In the ball slot, the lock and the outer casing will be separated from each other, and the lock can be taken out, and the other lock core can be inserted into the outer casing, and the rotation is fixed. In the case of a piece, the outer circumference of the positioning ring will force the ball in the ball groove to enter the outer brick and the perforation, so that the lock core and the outer casing are fixed to each other to complete the replacement of the lock core. When the bad resignation maintenance person g ^ 义, M, ^ people privately set the key to open the lock of the coin-operated device, the payment I, 卩目目,, 茨铛延 can not be opened The lock of the lock has been replaced, so that the store or the manufacturer can accompany the security of the property, and reduce the cost of replacing the lock and shorten the replacement time.
