Non-radial pin/hole lock for changeable lock cylinder

The invention relates to a non-radial pin/hole lock for a stackable lock cylinder, in particular to a lock for installing a stop pin or a lock bead without wearing a radial hole on the lock body.

At present, a common lock usually includes a body, a lock cylinder and a lock bolt, wherein one end of the lock bolt is installed in the body, so that the lock bolt can be connected with the body, and when the lock is to be locked, the user locks again. The other end of the plug is inserted into the body and the lock core is fastened to each other to complete the locking operation.

a conventional lock structure, in order to block the lock from being separated from the body, as shown in FIG. 9 , a first radial hole (82) is bored in the body (81), and the first radial hole (82) 82) is inserted into a pin (83), the pin (83) is transversely blocked on the moving path of the latch (84); and the second radial hole is bored in the body (81) (85) for mounting components such as the bolt (86) to achieve the function of locking. After the bolt (86) is installed, a plunger (87) must be embedded in the second radial hole (85). ) to close the second radial hole (85); and the lock core (88) is provided by a positioning pin (89) radially interposed between the body (81) and the lock cylinder (88) fixed.

Therefore, in the above-mentioned conventional lock structure, since the pin (83), the plunger (87) and the positioning pin (89) are installed, it is necessary, but the following disadvantages are caused: 1. The lock body (81) Because the first radial hole (82) and the second radial hole (85) and the radial hole for inserting the set pin (89) must be worn, the complete surface and structural strength of the body (81) is destroyed; 2. When the pin (83), the plunger (87) and the positioning pin (89) are driven radially in the body (81), the pin (83) and the column protruding from the body (81) must be removed. The plug (87) and the positioning pin (89) are ground and polished, so that the surface of the lock is smooth and flat. In addition, plating is also applied to shield the pin (83) and the plunger ( 87) and the gap marks generated between the positioning pin (89) and the body (81) cause manufacturing troubles and increase manufacturing costs.

In view of this, the inventors of the present invention have added research and innovation, and have revealed that the present invention discloses a non-radial pin/hole lock with a lockable core.
