Description

The turn lock bolt

Technical field

The utility model belongs to the door lock bolt, particularly a kind of turn lock bolt

Background technology

The lock bolt of present tubular lock, mainly constitute by locking device, driving member and lock crossbar box, be the knot form that is connected mutually between the three, and lock crossbar box mainly is to be installed in the perforation of door-plate, because the three is for linking form, so palpus SC when installing, the locating hole of driving member must be kept vertical with door-plate, promptly be that locating hole must be level with the reference column of tubular lock, otherwise when lock bolt is loaded on the door-plate, because of the perforation of lock crossbar box and door-plate can tighten, to adjust just suitable difficulty of angle this moment again.And industry has the people at this problem, design a kind of member that adds formula, add a sleeve again in the lock crossbar box outer rim, lock bolt can be rotated in sleeve, as United States Patent (USP) etc. 5,574, can see this kind type of service No. 346, shown in the 7th figure and the 8th figure, it mainly is at general tool locking component (61), the lock bolt (60) that driving member (62) and lock crossbar box (63) are formed, driving member (62) is provided with the locating hole (621) by tubulature shape lock, be between driving member (62) and lock crossbar box (63) and be one, can't move in relative rotation, so in addition at lock crossbar box (63) the sheathed sleeve of outer rim (64), lock bolt (60) can be inserted in the perforation (71) of door-plate (70), and with the surperficial formed grinding tooth clip of sleeve (64) in the perforation (71) inner edge surface, lock bolt (60) then can rotate in sleeve (64) adjusts angle, design by this, make lock bolt (60) adjustable angle be parallel with door-plate (80), and it is vertical to allow locating hole (621) and door-plate (70) on the driving member (62) form, and the backstay of the lockset of tubular lock can be locked by passing in the locating hole (621) of door-plate (70) lateral vertical.

Though above-mentioned United States Patent (USP) can utilize the assembling of sleeve (64), make lock bolt (60) can adjust angle, after inserting the door-plate perforation, common lock bolt can't adjust the corresponding angle problem and solve, but this sleeve (64) structure, it is the extra design of part of adorning other that increases, rather than on the overall structure of former lock bolt (60), improve, like this except the increase material on making, outside time and the cost, the stock that more need additionally get the raw materials ready, and, it is not to be the global design of former lock bolt, it need increase the step that wears of sleeve and lock bolt, as the setter inadvertent, sleeve is not placed in the lock crossbar box outside earlier, when promptly installing, just can adorn the facts of peace inconvenience again, therefore, it is the global design of non-former lock bolt, and exist practicality and do not reach problems such as increasing cost by force, thereby remain further to be improved.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of turn lock bolt is provided, it is the latch structure improvement about a kind of tubular lock, especially a kind of extra components that do not need is intended to change the lock crossbar box structure Design, can reach the practicality latch structure that rotatable adjustment lock bolt is established angle.

The technical solution of the utility model is:

A kind of turn lock bolt, the tubular lock belt case is arranged, form with the lock core of forming by locking component and driving member, it is characterized in that: locking component is by the activity template of a perforation and locating hole, on locating hole, be inserted with a reference column, the plunger latch head end is by a jack and protuberance, and sheathed spring between protuberance and the reference column, plunger latch head jack are inserted with a latch board with inside groove; Transmission mechanism has one to separate the door bolt plate, its front end bending is hook plate, he pass the perforation of portable plate and hook in the inside groove place of latch board, also have two correspondences and be first side plate and second side plate of engaging, separating a door bolt plate and a driving cam is coated in first side plate and second side plate, first side plate and second side plate are provided with locating hole, and respectively are provided with the hook portion that bends to outer rim at front end, and hook is in the perforation of activity template; Lock crossbar box is a circular shell, contracts in the shell end to form a baffle ring, and activity template leans against the baffle ring inboard, and front end has a panel and a locating ring with open-work, and locking component places in the lock crossbar box, and plunger latch head passes the open-work of panel; Driving member is passed by the lock crossbar box end.

Locking component has an antitheft door bolt that draw-in groove is arranged, the antitheft door bolt plate that clip slot is arranged, with one locating piece arranged only fasten plate with a bolt or latch, a locating hole is arranged on the activity template, only fastening plate one end with a bolt or latch inserts in the locating hole of activity template, the clip slot of antitheft door bolt plate is clipped in the draw-in groove of antitheft door bolt, antitheft door bolt and only fasten between the locating piece of plate cover with a bolt or latch with spring, in the antitheft first side of lock bolt that is latched in.

The utility model effect is:

This turn lock bolt is the architecture advances of tubular lock belt, and this improves design, makes tubular lock belt, under the prerequisite that need not add sleeve, when being installed in door-plate perforation back, still can rotating the adjustment angle, and allow the backstay of tubular lock belt reach correct installation in insertion easily.
