Description

The oblique tongue lock pin lock of band insurance

Technical field: the utility model relates to a kind of oblique tongue lock pin lock with insurance, belongs to five metals lockset industry.

Background technology: the Guli Security Products Co., Ltd. in Chinese Guangdong province Zhongshan city has carried out multinomial research to the core-inset type safe-guard door lock, and applied for the utility model patent of a key name on December 31st, 2002 for " core-inset type safe-guard door lock ", application number is: 02250803.1, it is tiltedly increasing Inclined bolt direction changing mechanism on the tongue, can be in the very short time (a few minutes) direction of oblique tongue is changed, to adapt to the needs of L.H.flapped door or R.H.flapped door; And at located lateral plate of square tongue spare top increase, make lock body can bear bigger pressure, thereby overcome some weakness of lock pin lock, become more practical, and theftproof performance is good.On this basis, the said firm is used in this technology on the mortise door lock of single oblique tongue, and is easy to by the weakness of inserting, being prized at the mortise door lock of single oblique tongue, has proposed the oblique tongue lock pin lock of a band insurance, thereby solve the problem of theftproof performance difference, task of the present utility model that Here it is.

The utility model content: the purpose of this utility model provides a kind of oblique tongue lock pin lock with insurance, increases by one group of safety tongue assembly in oblique tongue assembly bottom, makes oblique tongue be in safety position when locking, reaches the purpose of anti-plug, pick-proof; The overlapping oblique tongue slide block of two structural similarities on the lock body bottom circular aperture, thus make outer handle can not open oblique tongue, people outdoors can not come in, and interior handle can be opened oblique tongue, and the people in the door can go out, and has realized the effect of insurance.The utility model is design like this: the top at lock pin lock lock body keeps Inclined bolt direction changing mechanism, thereby makes this lockset that commutation function be arranged, and makes oblique tongue have two towards function, and can commutate easily.On lock panel, connect a safety tongue assembly in oblique tongue assembly bottom then, safety tongue assembly bottom connects the safety tongue junction plate, the safety tongue post that connects at the safety tongue junction plate nails on and has connected two safety tongue torsion springs, and the torsion spring of bottom is responsible for the return effect after the translation of insurance junction plate; One end of the torsion spring on top connects oblique tongue baffle plate assembly, can promote oblique tongue baffle plate assembly and nail on, descends tilting around flapper column; When its left-hand component was upturned, its head just withstood oblique tongue assembly rear end, and oblique tongue is unable to stir any more, and plays safety effect.When being upturned, tiltedly the tongue assembly is not blocked, and promptly removes the insurance to oblique tongue assembly when its top, the right (the promptly terminal hook of dialling), and tiltedly tongue can withdraw, stretch out.It more than is the case of machines of first design feature safety tongue assembly of the utility model.Tiltedly the rear end of tongue baffle plate assembly is connected on the oblique tongue sliding piece assembly, tiltedly tongue shifting component lower end connects lock core, the bottom of upper end connects first oblique tongue slide block, first oblique tongue slide block lower end connects oblique tongue slide block packing ring, tiltedly the lower end of tongue slide block packing ring connects second oblique tongue slide block again, the lower end of second oblique tongue slide block is connected in the slide block circular hole of lock body bottom, the right-hand member of first, second oblique tongue slide block connects oblique tongue simultaneously and stirs spring, and the rear end that oblique tongue is stirred spring is connected on the end plate of lock body.The oblique tongue slide block of two same structures overlaps, and this is another design feature of the present utility model, it makes each oblique tongue slide block corresponding to a handle, have only the interior handle that directly is connected with it to open the oblique tongue that is in safety position, and the outer handle oblique tongue of when tiltedly tongue is in safety position, not opening, must start lock core with key, lock core promotes oblique tongue sliding piece assembly could arming.According to above analysis, we can understand the utility model has the advantages that such: (one) reasonable in design, simple in structure, the assembling compact.(2) tiltedly tongue is accomplished anti-plug, pick-proof behind locking, does not have the key door of not opening.(3) the overlapping diclinic tongue slide block of utilization really makes handle inside and outside different, and inside and outside handle acts in accordance with the division of their functions and duties.
