Description
Technical field
The utility model relates to a kind of door-inhale having gathering structure.
Background technology
Common door-inhale comprises surely dynamic two pieces, and moving part is arranged on wall or ground, and locking member is arranged on the angle of door.Having a kind of door-inhale to be locking member is a bowl-type ironware, and moving part is end the shaft of magnet.Described moving part butt is arranged on the back side of limit inferior horn outdoors, although it is mounted in behind the door, door has after all the ridge that is long, as can bump to because of carelessness pin or other, make to cause damage.Chinese utility model patent " a kind of theftproof lock (patent No.: ZL201420756422.7) with stealthy door-inhale " describes " a kind of theftproof lock with stealthy door-inhale, comprises latch fitting, and lock section in latch fitting, handle, have a door attraction device in described latch fitting.Described door attraction device comprises: a coil tension spring is located at latch fitting inner top, and coil tension spring bottom connects a pull bar, and pull bar end is fixed with soft door-inhale part, and there is a free gear described handle one end, and described pull bar top has and drives with free gear the teeth portion be connected." but this door-inhale is the frictional force realization on relative ground, unreliable.
Summary of the invention
For above-mentioned deficiency, the utility model be exactly to provide a kind of perpendicular to the shop front, having of having shaft moving part draw the door-inhale of structure in.
What the utility model provided have draws the door-inhale of structure in, comprises shaft moving part, pull bar and spanner, and the butt of described shaft is fixed on a perpendicular axle, and beam warp axle bed is arranged on housing, and housing is inlaid in door-plate, and axle phase end of door plate face is parallel; Described axle is coaxially arranged with cylindrical cam, and the thimble of cylindrical cam is arranged on housing through slide mechanism; The cam line of described cylindrical cam is the section spiral line on cylinder cylinder, and the angle of this place, helix two ends radial line on axis projection is right angle; Housing there is also mounted a swing shift fork, shift fork hook connects thimble and pull bar, and pull bar upper end is connected with the eccentric point of spanner; The two ends of thimble stroke are positioned shaft perpendicular to door-plate be parallel to door-plate respectively relative to the angle that cylindrical cam rotates.
What the utility model provided has the door-inhale drawing structure in, cylindrical cam mechanism is utilized the translational force of spanner to pull bar to be converted to the twisting resistance of door-inhale male part according to the rotation of its axle, when spanner by pull bar shift fork time, moving part according to its axle swing, make itself or perpendicular to door-plate or fold into door-plate.Compared with prior art, it is folding and draw in door that the utility model achieves the door-inhale male part that level is installed, simple to operate and reliable.
The cam line of described cylindrical cam is the helix groove engraved on cylinder, and thimble is the slide block with slot fit, drive respectively when thimble reciprocates cylindrical cam reverse and clockwise.
The cam line of described cylindrical cam is that the hand of spiral is identical and end face points to contrary spiral yarn shaped step on cylinder two, thimble having two push end is against on two spiral yarn shaped steps respectively, drive respectively when thimble reciprocates cylindrical cam reverse and clockwise.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment, Fig. 2 be in Fig. 1 A to partial view, in figure: 1-housing, 2-swing arm, 3-spanner, 4-pull bar, 5-shift fork, 51-is subject to the arm of force, 52-force arm, 6-thimble, 7-axle bed, 8-shaft, 9-cylindrical cam, 9a-cam line, 10-axle, 11-door-plate.
Detailed description of the invention
1, one has the door-inhale drawing structure in, and have housing 1, housing internal fixtion has a pair axle bed 7, and on axle bed, level installs an axle 10, and the stage casing of axle is a cylindrical cam 9, and cylindrical cam middle point vertical is fixed with the shaft 8 as door-inhale moving part.Cylindrical cam has cam line 9a, cam line is a spiral yarn shaped step having end face, and spiral yarn shaped step accounts for 1/4 cylinder, and namely the angle of sagittal plane, place, two ends is 90 °.Have the shaft-like thimble 6 that is parallel to axle, the end that pushes of thimble is against on the end face of spiral yarn shaped step, and thimble is arranged in housing by slide opening.Housing has also installed a shift fork 5 by rotating shaft, and the force arm 52 of shift fork is inserted in hole that thimble is opened, shift fork hinged by the arm of force 51 and pull bar 4, is elongated hole by hole hinged with pull bar on the arm of force.Pull bar lower end is arranged in housing through slide opening, and upper end is hinged with the eccentric point being fixed on the swing arm 2 on spanner 3.Housing is embedded in door-plate 11, and when thimble is pressed onto the end to cylindrical cam top, door-inhale moving part shaft is vertical with door-plate; Shift fork is subject to the arm of force and cylindrical cam in the same side, when pull bar is upwards carried, force arm promotes thimble and presses to cam line.Spanner is arranged on door-plate through resisting force sheet, and when shaft turns to vertical with door-plate through pull bar, shift fork by spanner rotation, the resistance of cam mechanism and resisting force sheet can stop shaft to fall after rise; When pull bar is loosened in spanner rotation, cylindrical cam loses top power, and then shaft is sagging under gravity.Door-plate and housing have the breach extending to bottom on the position having shaft, movable for shaft.
2, as above example, wherein cam line has been the section spiral line shape groove on cylindrical cam, and slot bottom width is greater than notch, thimble push end be the slide block be engaged in groove, slide block move back and forth to cylindrical cam apply forward and backward revolution move power.Make cylindrical cam forward and backward revolution controllability strong.
3, as example 1, wherein spiral yarn shaped step is arranged side by side two, and two cam lines are that end face is opposing.Thimble protrudes two push end and offset with two end faces respectively, thimble moves back and forth and applies the dynamic power of forward and backward revolution to cylindrical cam.Make cylindrical cam forward and backward revolution controllability strong.
