Description

Curtain pelletron wheel

Technical field

The utility model relates to the improvement of a kind of curtain pelletron wheel, refers to a kind ofly to establish simplifications especially, assembly is simple, and the curtain pelletron of simple operation is taken turns.

Background technology

Live in people by curtain has finding more, and the principle of cord (portion) can be batched or discharge to its utilization, curtain must be thought meet the operation requirement of covering light or not covering, see through the improvement of curtain, make door and window can be the selection of shading or printing opacity,, truly have its needs people's life.

In order to reach the operation purpose, the structure of curtain, except the curtain sheet that can be batched or discharge, the one side is the curtain pelletron wheel of title that people practise, by the meshing relation between pelletron wheel and pelletron, and reach the effect of batching or not batching, and wherein said pelletron is formed by the continuous jointless pearl body of circle circle shape is connected in series.

Known curtain pelletron wheel, as No. 87216683 patent application case in Taiwan (notification number is No. 360028), " curtain pelletron wheel ", in this case, disclosed by the pearl axle, pearl refining seat, trepanning, members such as fixed block are formed, it can reach basic function admittedly, only disappearance is because pelletron is the circle circle shape that is connected in series by some pearl bodies, therefore, in when assembling must energy " centering on " in bead chain base, must be with behind its decomposition and the cover " centering on " of going ahead of the rest, could organize and stand, and its member is many, and need to use with Locking screw as screwdriver, the difficulty victory of finding a great convenience, finished product also therefore improve, and can be rated as a fly in the ointment.

The utility model content

The purpose of this utility model is to provide a kind of curtain pelletron wheel that can overcome above-mentioned disappearance.For achieving the above object, the curtain pelletron wheel that the utility model provides, it comprises:

One outer seat, its tool one outer sheet, central vertical is extended an external cylindrical base, the external base core group that the external base core that its one elongated end place is tool arrow-shape end place is formed, and the seat rank of front end tool size drop; Other unifies spring by the seat jacket casing, and each tool one spring of end place is prominent; And one section outer seat loop of vertical extension on the outer seat sheet;

One pearl seat links a circle by a seat ring is vertical, and the pearl chamber of the some bead supporting body devices of seat ring periphery tool is run through in its hole of central tool;

Cover in one, its by one and external diameter bigger in the sheet that contracts forms, and tool one endoporus runs through, the inner core inwall is with rank of size drop formation;

Be sleeved on external cylindrical base by the pearl seat, and the outer seat of external cylindrical base is with the endoporus of cover in passing and to be sticked in its outer rim be the group position of halting, and seat rank are that seat ring can not covered by outer seat loop when being sticked in tin rank.

Described curtain pelletron wheel, wherein seat ring must be opened slotted eye, and the prominent sheet hook of establishing is thought and hooked together interlock on the interior ring plate.

By enforcement of the present utility model, its assembly is few, and the time need not by instrument in assembling, more can form interlock by the buckle of sheet hook and slotted eye, but makes locking phase externally be the variation in space.

The specific embodiment

For further describing concrete technology contents of the present utility model, at first see also accompanying drawing.

As shown in the figure, basically, curtain pelletron wheel of the present utility model is by outer seat 1, one a pearl seat 2, and 3 in cover combines in one.

Wherein, outer seat 1 in its by one outside a sheet 11 its central vertical extend an external cylindrical base 12, in this external cylindrical base 12, and then extend one group of external base core group 13 with one heart, as shown in the figure, this external base core group 13 is separately to be formed by the only central tool heart of two external base cores 131 groove 132.The external diameter of the elasticity group that change is enclosed of its tool appropriateness, that is it can be and is subjected to outer and two external base cores 131 are contracted in being, reply again after only external force discharges to enclosing and form big external diameter, and after respectively the front end of this external base core 131 is oblique outer expansion, 133 backs, seat rank that are tool one drop again are the isometrical body of rod, simultaneously, for enabling the pelletron at standard top, therefore, outer seat sheet 11 outer rims of outer seat 1, the one one section outer seat loop 111 that extends internally, in addition, on the external cylindrical base 12, get subtend and open one scarce 121, and get snare one spring 122, and the initial spring prominent 123 of these spring 122 tools.

Pearl seat 2 its holes 21 of central tool, its size is greater than the external diameter in aforementioned outer seat hole 12, but fit, and it is by an a seat ring vertical circle 23, the periphery of this seat ring 22, the pearl chambers 221 that the some isogonisms of tool are provided with of extending 22, for each pearl body and function of ccontaining pelletron, this is a known technology, so do not intend giving unnecessary details.And the place, two ends of seat circle 23 then is to be the circle edge 231 of backstop for aforementioned spring prominent 123, and in addition, for the interior cover of chatting after pearl seat 2 be can be 3 drives, therefore, seat ring 22 can be opened at least one slotted eye that runs through 222.

In cover 3 be to link the bigger interior ring plate 32 of external diameters by an inner core 31, and central tool one runs through endoporus 33, the tube rib 311 of several projections must be established in these inner core 31 peripheries, this is a known technology, so do not intend giving unnecessary details.And the inside of inner core 31 then forms rank 312 so that internal diameter is different, and the aforementioned slotted eye 222 of 32 correspondences of interior ring plate is provided with sheet hook 321, thinks to hook together.

See also accompanying drawing, when the utility model is implemented in reality, pearl seat 2 is sleeved on external cylindrical base 12, and interior cover 3 is sleeved on a circle 23 and external cylindrical base 12 by endoporus 33, external base core group 13 then can pass inner core 31 and be snapped in endoporus 33 outer rims of inner core 31 with seat rank 133, the formation group is found state, and sheet hook 321 fasteners are in slotted eye 222.

When desiring the corral pelletron, as shown in the figure, then only need folder to pinch external base core 131 and make and overlap 3 in it together with pearl seat 2 outer taking off, this moment is because sheet hook 321 is fastened on slotted eye 222 also for driving, wait a rank 312 when being snapped in rank 133, then this moment, pelletron A can enclose the seat ring 22 that closes in pearl seat 2, and make pearl body B be positioned pearl chamber 221, then, then again folder pinch external base core 131 and with interior cover 3 together with pearl seat 2 outward seat 1 direction push away, promptly form the location, when desiring to be replaced as maintenance pelletron A, then be pulled outwardly, can make pelletron A break away from this device for counter.

So, via enforcement of the present utility model, its assembly is few, and when assembling, need not by instrument, in addition can be via seat rank 133 clip with tube rank 312, and be the relaying location for installing pelletron A, into person is arranged especially, more can form interlock with the buckle of slotted eye 222, but make the external seat of locking phase be the variation in space by sheet hook 321.

The utility model is described, is a kind of of preferred embodiment, and patent right category of the present utility model is not all taken off in Ju Bu change or modification and come from technological thought of the present utility model and be to have the knack of this technical staff to be easy to know by inference such as.
