Description

A kind of inserted coupling device by telescopic location

The invention belongs to a kind of coupling, particularly belong to a kind of inserted coupling device by telescopic location, form by telescopic positioning screwn and adapter sleeve two-part.

The present invention is particularly suitable for being applied to needing being located by connecting fast and dismounting fast between dismounting and the folding member.If can also carry out remote control at the suitable electrical equipment of operating position configuration is located by connecting fast and dismantles.

The various embedded coupling device that can see on the market at present,, most species most widely used with furniture industry.By the combination of member based on mutual vertical overlap joint.The embedding Placement of coupling device mostly is such; There is the pin of annular groove to embed the end of a module component end, and stretches out the distance that component ends one is fixed; The eccentric annulus of another kind of band cover embeds by the in-plane of another module component.When two module components link to each other, pin is inserted in the eccentric annulus.Rotate eccentric annulus then, at this moment the position between two members produces displacement by the size of eccentric annulus throw of eccentric and draws close, thereby finishes fasteningly, and vice versa.This Embedded coupling device has a lot of deficiencys, at first is to embed to install to be difficult for firmly, and pin is easy to pull out outward along the embedded hole of component ends; The extrusion of pin has strict requirement simultaneously, and it is subjected to the restriction of eccentric annulus throw of eccentric size, in case occur wearing and tearing between pin and the eccentric annulus, then becoming flexible will appear in the connection between two members; In addition since eccentric garden ring when rotating, fastening pressure progressively increases, eccentric garden ring is also increasing with the contact friction force of pin annular groove, fastening pressure between two members is hindered and the raising of join strength is restricted; Because of pin stretches out component ends, also bring a lot of obstruction for installation and removal; If there is the polylith member to connect simultaneously in space range by multiple orientation, multiple angles, multiple overlapping mode, so this existing embedded coupling device just can not adapt to more.

The purpose of this invention is to provide a kind of inserted coupling device by telescopic location, make the member or the object that need to connect, by different overlapping modes, different positions, different angles is connected simultaneously with a plurality of quantity and dismantles and be not subjected to any obstruction.

In conjunction with the accompanying drawings, describe the present invention below in detail:

Inserted coupling device by telescopic location is made up of telescopic positioning screwn and adapter sleeve two-part.Telescopic positioning screwn is that an assembly parts constitutes (see figure 1), is the sectional view that embeds in member (10) plane, is made up of pedestal (1), front gear (2), backgear (3), horizontal gear (4), pressure ring (5), pull bar (6) and handle (7).It is such that its structure is installed with acting on:

Pedestal (1) (see figure 4) embeds member (10) from in-plane radially a through hole (15), supporting rod (6) is played at middle part, hole (16), two ends have forward recess (17) and rear groove (18) to lay front gear (2) and backgear (3) respectively, and communicate with the hole of member (10) end face; Front gear (2) (see figure 5) endoporus (19) is a right-handed thread, backgear (3) (see figure 6) endoporus (20) is a left-handed thread, with horizontal gear (4) be one group of driving gear, there is irregularly-shaped hole (21) at the back side of horizontal gear (4) (see figure 7), for special rotating tool it is rotated, avoid just it to be rotated, therefore have certain safety with the common tool that revolves; Pressure ring (5) is pushed down horizontal gear (4) does not allow driving gear set deviate from from pedestal (1); Be the tail end of through hole (15) with having two symmetrical plane of orientations (22) and (23) to be pressed into pedestal (1) in reversing handle (7) the (see figure 8) endoporus, so far just finished installation based on pedestal (1).Then pull bar (6) is inserted from the end face through hole of member (11) in the through hole (15) of pedestal (1).Pull bar (6) (see figure 9) is made up of head, middle part and afterbody three parts: between the 50-60 degree, form by drag hook corresponding points (25) and (26) and positioning rod (27) by guiding awl (24) its cone angle for head; The middle part is made up of right-handed thread (28) and left-handed thread (29), and right-handed thread (28) combines with the endoporus (19) of front gear (2), and left-handed thread (29) combines with the endoporus (20) of backgear (3); Afterbody has symmetrical guide surface (30) and (31) to combine with plane of orientation (22) and (23) of handle (7), rotate counterclockwise horizontal gear (4) then pull bar (6) to protracting, otherwise then contract backward.

Adapter sleeve divides two types, (see figure 2) is that adapter sleeve (8) embeds the sectional view in the plane of member (11), (see figure 3) is that adapter sleeve (9) embeds the sectional view in the plane of member (12), the structural feature of the adapter sleeve of these two types (8) and (9) is the same, fixed endpoint (13) and (14) that drag hook corresponding points (25) and (26) with pull bar (6) of distributing symmetrically in the hole of adapter sleeve (8) and (9) match.

Be connected and the dismounting of member (10) and member (11) are achieved in that draws close member (10) and member (11), lift handle (7) since plane of orientation (22) and (23) to the guide surface (30) of pull bar (6) and the effect of (31), adjust the orientation angle of pull bar (6), then counterclockwise rotate horizontal gear (4) then pull bar (6) play a part to lead in the hole of the adapter sleeve (8) that stretches to member (11) by guiding awl (24), positioning rod (27) then plays the locating stud effect that member (10) is connected with member (11), lifting handle (7) once more allows the drag hook corresponding points (25) of pull bar (6) and (26) overlap at the fixed endpoint (13) of adapter sleeve (8) and the below of (14), and then clockwise direction rotates horizontal gear (4), at this moment shrink back backward and the fixed endpoint (13) of adapter sleeve (8) and the restriction of (14) owing to pull bar (6), be connected fastening purpose thereby make member (10) and member (11) be issued to, have no otherwise two members (10) thoroughly separate with (11) to hinder in the continuous rotation of horizontal gear (4).As for being connected and dismounting of member (10) and member (12), similar to the above, institute's difference only is joint form, and the former is the vertical overlap joint of end face with the plane, and the latter is that end face docks with the plane of end face.Be located by connecting fast and dismantle if carry out remote control, as long as operate horizontal gear (4) and handle (7) electric consumer and remote control unit just passable.

Known to above-mentioned, the present invention and existing embedded coupling device have basic difference, change the existing fixing pin that protrudes from member into can stretch, can contract, can reverse, can lead, can locate, can strain multifunctional movable pull bar, guiding, location, fastening and dismounting are integrated; Change eccentric garden ring into fixed endpoint, have only between pull bar and the fixed endpoint to contact and do not have pivoting friction, thereby the join strength between the member can improve greatly; Because it is pull bar (6) is to move in the gear train of front gear (2) backgear (3) and this equilibrating force system of horizontal gear (4), therefore capable of expansion and contraction, fastening all very light laborsaving with dismounting; Simultaneously, because the telescopic nature that had of pull bar (6) and being hidden in the member body has brought convenience for the connection and the dismounting of member.Existing member is when connecting, to make a module component previous generation have the pin of protrusion to insert in the hole of another piece band eccentric hoop member earlier, fastening then, so the pin of this protrusion has just become the obstacle of free connection and dismounting, limited the Placement of member, the Placement that this in general existing embedded coupling device can be suitable for can only be carried out in sequence at single in-plane.And the present invention has utilized the telescopic nature of pull bar (6) just, has overcome above-mentioned defective, makes the connection of member become and earlier member is drawn close, and pull bar (6) stretches out and retreats and reach fastening then, on the contrary dismounting.Therefore can make member by different overlapping modes, different positions, different angles and being connected and dismantle energy and freely carry out in a plurality of quantity are carried out space range.Because adapter sleeve (8) and (9) all are to embed member from in-plane, thereby have overcome some member, when end face embeds, owing to the strength of materials is not enough, and the not firm shortcoming of embedding.

The present invention constantly can be applied to furniture industry, also can be widely used in the place that members such as machinery, electronics, building or object need connect repeatedly and dismantle.
