Abstract
The utility model relates to an anti-theft device, in particular to a lock allowing flexible door opening and closing, and solves the problems that during closing of a traditional anti-theft door, fire door, steel door or wood door, both the latch bolt and the lock catch of the lock are in sliding friction, so that the door can not be flexibly closed, and abrasion of the lock bolt is easily caused, and when the door is closed by an excessive force, damage of the lock is extremely easy. The lock provided by the utility model comprises a lock catch corresponding to a lock bolt on one side of a locks body, wherein a roller in running fit with the lock catch is arranged on one side of a locking slot of the lock catch; and the lock bolt and the roller are in rolling fit with each other. The lock provided by the utility model has a simple structure and is convenient to assemble; during closing a door adopting the lock, the lock bolt is in rolling fit with the roller in the locking slot, and the rolling friction replaces the sliding friction between the present lock bolt and lock catch, so that the friction coefficient is greatly reduced and the door can be flexibly closed.
Description
Technical field
The utility model relates to a kind of anti-theft appliance, refers in particular to a kind of lockset of flexible switch gate.
Background technology
Tradition security door, labeled door, steel door or timber are when switch gate, and the latch bolt of lockset is done sliding friction with snap close, cause that switch gate is dumb sometimes, and cause easily the wearing and tearing of dead bolt, when switch gate exerts oneself very easily to cause the damage of lockset itself when excessive.
The utility model content
The technical problem that one, will solve
The purpose of this utility model is for the existing the problems referred to above of prior art, and the spy provides a kind of flexibly lockset of closing the door simple in structure; When switch gate, dead bolt rolls with roller on being arranged on snap close and cooperates, because coefficient of rolling friction less than the coefficient of sliding friction, is realized flexible switch gate.
Two, technical scheme
For solving the problems of the technologies described above, the utility model lockset includes the snap close corresponding with the dead bolt that is arranged on lock body one side, and wherein, locked groove one side of above-mentioned snap close is provided with the roller that is rotatably assorted with snap close, and above-mentioned dead bolt rolls with roller and cooperates.
As optimization, the up and down inwall of above-mentioned locked groove has the through hole of coaxial correspondence, and the two ends of above-mentioned roller are provided with through hole and cooperate the inserting column of pegging graft, and above-mentioned roller is plugged in the locked groove.
As optimization, above-mentioned inserting column cooperates with via clearance.
As optimization, the fitting face of above-mentioned dead bolt and roller is arcwall face.
Three, the beneficial effects of the utility model
Simple in structure, easy to assembly; At closing time, dead bolt is realized rolling with the roller in being arranged on locked groove and is cooperated, and with the sliding friction between the existing dead bolt of its rolling friction replacement and the snap close, friction factor reduces greatly, thereby realizes closing the door flexibly.
Description of drawings
Below in conjunction with accompanying drawing the utility model lockset is described further:
Structural representation when Fig. 1 is the unlatching of the utility model lockset;
Sectional schematic diagram when Fig. 2 is the unlatching of the utility model lockset;
Fig. 3 is the structural representation of the utility model lockset when closing;
Fig. 4 is the sectional schematic diagram of the utility model lockset when closing.
Among the figure, 1 is lock body, and 2 is dead bolt, and 3 is roller, and 4 is snap close, and 5 is locked groove.
The specific embodiment
Embodiment one: as shown in Figures 1 to 4, the utility model lockset includes the snap close 4 corresponding with the dead bolt 2 that is arranged on lock body 1 one sides, wherein, locked groove 5 one sides of above-mentioned snap close 4 are provided with the roller 3 that is rotatably assorted with snap close 4, and above-mentioned dead bolt 2 rolls with roller 3 and cooperates.Above-mentioned lock body 1 can be any one of existing lockset, can arbitrarily change according to user's user demand, and above-mentioned snap close 4 is to be installed on the doorframe that corresponding with lock body 1, its locked groove 5 that is arranged on the snap close 4 is corresponding with dead bolt 2.
The up and down inwall of above-mentioned locked groove 5 has the through hole of coaxial correspondence, and the two ends of above-mentioned roller 3 are provided with through hole and cooperate the inserting column of pegging graft, and above-mentioned roller 3 is plugged in the locked groove 5; Above-mentioned inserting column cooperates with via clearance; Above-mentioned dead bolt 2 is arcwall face with the fitting face of roller 3.
The user is at closing time, and the arcwall face of dead bolt 2 touches the outer wall of roller 3, along with the increase of door closing force, dead bolt 2 is on the one hand to lock body 1 interior indentation, and on the other hand, dead bolt 2 carries out rolling friction with roller 3, make dead bolt 2 as easy as rolling off a log entering in the locked groove 5, thereby reach the purpose of closing the door flexibly.The user is when opening the door, and dead bolt 2 carries out rolling friction with roller 3, makes dead bolt 2 as easy as rolling off a log being withdrawn into beyond the locked groove 5, thereby reaches the purpose of opening the door flexibly.
Claims (4)
