Abstract
Disclosed is an adjusting device of extruding length of a cylinder. The adjusting device is characterized in that the adjusting device is provided with a cylinder sleeve, an adjusting sleeve and a fixing screw, wherein one end of the cylinder sleeve is fixed on a cover board of the lock body, the adjusting sleeve is arranged outside the cylinder via pivot sleeve and the fixing screw is disposed on the cylinder. An adjusting slot is provided on the periphery wall of the cylinder sleeve along the direction of a shaft. And on the periphery wall of the adjusting sleeve an adjusting slot is spirally mounted. The fixing screw pierces a cavity formed by the convergence of the two adjusting slots and is wrung into a screw hole of the cylinder. The utility model has the advantages of simple structure, convenient and rapid operation and convenient manufacture.
Description
The utility model is about cylinder lock, particularly about the adjusting device of tapered end extension elongation.
Door lock is the widely used Hardware fittings of all kinds of buildings, and wherein pin tumbler lock then is commonly client's employing.Pin tumbler lock is divided into tapered end lock body and keeper three parts.Protruding doorframe one side that places of keeper wherein; Tapered end then is arranged in perforated holes default on the door-plate, its front end has the shoulder portion of the tapered end circle clip that is positioned at the door-plate antetheca, the other end has three screws, be screwed into this three screws by three three tapered end screws that pass the three eye plates/cover plate that is arranged in the door-plate rear wall, tapered end is fixedly clamped on door-plate; Lock body then is convexly set on the door-plate rear wall.This fixed structure of tapered end is screwed into length or the length of screw own and just can be adapted on the door-plate of different-thickness fixedly tapered end easily as long as change the tapered end screw.But easily cause visual discomfort because the evagination of lock body and keeper is provided with, destroy the harmony of interior decoration, be repugnant to the eye.Developed thus lock body and keeper also have been separately positioned on stealthy door lock in door-plate and the doorframe.Limited because of the thickness of door-plate, tapered end is not suitable for adopting existing fixed structure clamping by tapered end circle, three eye plates/cover plate and tapered end screw on door-plate again, but directly is fixed on the lock body, again with the lock body whole erection in the prefabricated chamber of door-plate.This lock body directly is fixed on structure on the lock body, can't adopts existing adjustment tapered end screw length to regulate the tapered end extension elongation to adapt to the door-plate of different-thickness.Special cause the recessed door-plate of tapered end too dark when door-plate is thicker, not only owe attractive in appearance, and also inconvenience of the operation of key.
The purpose of this utility model is to provide a kind of adjusting device of tapered end extension elongation, and it can make tapered end be fixed on the lock body with various different extension elongations easily, to adapt to the needs that stealthy door lock is installed on the different-thickness door-plate.
The purpose of this utility model is achieved in that
A kind of tapered end extension elongation adjusting device is characterized in that: this adjusting device comprises an end and is fixed on tapered end cover, pivot on the lock cover and is enclosed within the outside regulating sleeve of this tapered end cover and is arranged on hold-down screw on the tapered end; Be provided with the adjusting slotted hole vertically on the perisporium of this tapered end cover; Spiral is provided with the adjusting slotted hole on the perisporium of this regulating sleeve; This hold-down screw passes through above-mentioned two and regulates that slotted holes cross and the hole that forms is screwed into the screw of tapered end.
Above-mentioned tapered end extension elongation adjusting device, it is characterized in that: the perisporium of tapered end is provided with axial direction recess; This tapered end cover internal perisporium is provided with the guiding tenon that embeds this direction recess.
Above-mentioned tapered end extension elongation adjusting device is characterized in that: the other end of this tapered end cover is provided with shoulder.
The utlity model has following advantage:
1. rotary regulating sleeve can carry out the stepless adjustment of tapered end extension elongation easily to adapt to the door-plate of different-thickness; Guarantee that tapered end flushes with door-plate.
2. simple to operate quick, except that general screwdriver, need not special tool.
3. simple in structure, the part of composition is few, is beneficial to manufacturing, installs.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the utility model structural representation.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is a tapered end nested structure schematic diagram.
Fig. 4 is an A-A mark sectional view among Fig. 3.
Referring to Fig. 1, the utility model is arranged between tapered end 1 and the lock body 6, and it comprises tapered end cover 2, regulating sleeve 3 and hold-down screw 7.Lock body 6 has the shell that lock housing 5 and cover plate 4 surround.Tapered end cover 2 is a hollow cylinder, and its bottom end face 13 (Fig. 4) is fixed on the corresponding site of cover plate 4.Be provided with vertically on the perisporium of this tapered end cover 2 and regulate slotted hole 11 (Fig. 3), its top is provided with shoulder 13.Tapered end overlaps 2 internal diameters and tapered end 1 external diameter is complementary, and moves freely in 2 or rotates so tapered end 1 can overlap at tapered end.For preventing the rotation of tapered end 1, axially be provided with direction recess 9 at the side face of tapered end 1, corresponding site is provided with guiding tenon 12 on 2 internal perisporiums and overlap at tapered end.The above-mentioned guiding tenon 12 of mat embeds in the direction recess 9, thereby tapered end 1 is moved axially in tapered end cover 2 only.The perisporium of tapered end 1 is provided with screw being screwed into for hold-down screw 7.Tapered end 1 one ends are provided with convex shoulder 10.Regulating sleeve 3 is enclosed within outside the tapered end cover 2, and its two ends are subjected to shoulder 13 restrictions of cover plate 4 and tapered end cover 2 to overlap rotation on 2 at tapered end respectively.The perisporium upper edge hand of spiral of this regulating sleeve 3 is provided with regulates slotted hole 8.When rotary regulating sleeve 3, can make it regulate slotted hole 8 and overlap 2 adjusting slotted hole 11 at different distance of distance cover plate 4 and tapered end and intersect.The hole that 7 of hold-down screws pass this intersection is screwed into screw on the tapered end 1 and fastening, regulating sleeve 3 and tapered end 1 location that promptly is fixed.So, can adjust tapered end 1 extension elongation easily to adapt to the door-plate of different-thickness.
Tapered end 1 can 180 ° be symmetrical arranged two hold-down screw 7 (see figure 2)s.At this moment, 2 in tapered end cover needs the corresponding adjusting slotted hole 11 that is provided with two alternate 180 °; Adjust the also corresponding adjusting slotted hole 8 that is provided with two alternate 180 ° of cover 3 with identical rotation direction.With two hold-down screws 7 and two pairs of forms of regulating slotted hole 8,11, stretching out of tapered end 1 had more steadily with firm like this.
