Abstract
The utility model discloses a kind of novel pressure adjustable door linkwork cylinder latch, primarily of shell, axle lower casing, junction plate, pin main body, screw, spring composition in rolling element, axle, shell in axle and axle lower casing are fixed together through junction plate by described screw, described rolling element and spring are positioned in the cavity in axle between shell and axle lower casing, described spring one end is pressed on junction plate, the other end compresses rolling element, and in described axle, shell and axle lower casing are positioned in the through hole in the middle of pin main body.The beneficial effects of the utility model: the rigidity that spring can be set according to environment for use, the active force of adjustment linkwork cylinder latch, effectively reduces the noise opening the door and produce at closing time; The easily worn part adopted is assembly, and when the part in assembly has damage, the main part of cylinder latch can also continue to use, and improves the economy of latch, is convenient to dismounting and maintenance.
Description
Technical field
The utility model relates to a kind of latch, particularly a kind of novel pressure adjustable door linkwork cylinder latch.
Background technology
In our daily life at ordinary times and study, especially have a rest in dormitory and classroom need we in enabling and significant care when closing the door class hour, avoiding opening the door and produce at closing time and wait comparatively loud noise to affect other people to have a rest or learn.Spring and autumn monsoon larger, usually because wind-force is crossed senior general's door and suddenly blown open and suddenly shut and frighten us, also cause the damage of door simultaneously thus bring economic loss.The door hinge connection mechanism that we use at present is mostly cylinder latch and rotates in cylindrical hole; usually can open the door because of cylindrical wearing and tearing and produce noise at closing time after of long duration; relative friction forces reduces simultaneously, and suddenly holding and suddenly closing phenomenon of door just can occur under wind-force effect.
Summary of the invention
The purpose of this utility model is exactly for the problems referred to above, and proposing one can by regulating spring pressure change door linkwork cylinder latch, the noise produced when effectively reducing door switch, and extends the application life of door hinge connection mechanism.
Its technical scheme is: a kind of novel pressure adjustable door linkwork cylinder latch, primarily of shell, axle lower casing, junction plate, pin main body, screw, spring composition in rolling element, axle, shell in axle and axle lower casing are fixed together through junction plate by described screw, described rolling element and spring are positioned in the cavity in axle between shell and axle lower casing, described spring one end is pressed on junction plate, the other end compresses rolling element, and in described axle, shell and axle lower casing are positioned in the through hole in the middle of pin main body.
In above-mentioned axle, shell is semicylinder structure, and mid portion is provided with a rectangular opening, and two ends are respectively equipped with a semicylindrical opening and semicircle taper hole and two minor thread holes.
Above-mentioned axle lower casing is identical with shell mechanism in axle.
The cross-section center position of above-mentioned pin main body is provided with a through hole.
The beneficial effects of the utility model: the rigidity that spring can be set according to environment for use, the active force of adjustment linkwork cylinder latch, effectively reduces the noise opening the door and produce at closing time; The easily worn part adopted is assembly, and when the part in assembly has damage, the main part of cylinder latch can also continue to use, and improves the economy of latch, is convenient to dismounting and maintenance.

In upper figure: 1. shell, 3. axle lower casing, 4. junction plate, 5. pin main body, 6. screw, 7. spring in rolling element, 2. axle.
Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As Figure 1-3, a kind of novel pressure adjustable door of the utility model linkwork cylinder latch, primarily of rolling element 1, shell 2 in axle, axle lower casing 3, junction plate 4, pin main body 5, screw 6, spring 7 forms, shell in axle 2 and axle lower casing 3 are fixed together through junction plate 4 by described screw 6, described rolling element 1 and spring 7 are positioned in the cavity in axle between shell 2 and axle lower casing 3, described spring 7 one end is pressed on junction plate 4, the other end compresses rolling element 1, in described axle, shell 2 and axle lower casing 3 are positioned in the through hole in the middle of pin main body 5.
Preferably, in described axle, shell 2 is semicylinder structures, and mid portion is provided with a rectangular opening, and two ends are respectively equipped with a semicylindrical opening and semicircle taper hole and two minor thread holes.
Preferably, described axle lower casing 3 is identical with shell in axle 2 structure.
Preferably, the cross-section center position of described pin main body 5 is provided with a through hole.
Described novel pressure adjustable door linkwork cylinder latch in use, sets the rigidity of spring 7, adjusts the active force of linkwork cylinder latch, make it effectively rotate in the cylindrical hole of linkwork according to the situation of environment for use.Effectively can reduce under suitable frictional resistance effect and open the door and the noise that produces at closing time, and wind-force is crossed senior general's door and suddenly blown open and suddenly close first-class problem, also avoid the damage because of door thus the economic loss caused simultaneously.In use procedure, each component assemble use, and when the part in assembly has damage, the main part of cylinder latch can also continue to use, and improves the economy of latch, is convenient to dismounting and maintenance.
