Abstract

The utility model relates to a multi-hook connecting piece. The lock hook of the multi-hook connecting piece is a piece part with a side hook at the end part, a slope shape salience is arranged on the opposite side of the side hook, the lock hook is overlapped and movably matched to be installed on a lock axle in an alternating arrangement along the side hook direction, a pin axle and a connecting slider are fixed, connected and movably matched to be arranged in a casing inner cavity to form a coupling hook component, because the lock hook adopts a piece part, by adopting the blanking process, the curved part without material cannot generate elastic deformation phenomenon to weaken the locking force, in addition, the adoption of the multi-hook interlacing double-sided connection balance the double-sided locking force, and the multi-hook connecting piece is uneasy to slide down, thereby, the connected material is effectively protected.

Description

A kind of many hooks link

Technical field: the utility model relates to a kind of many hooks link, exactly, is to be used for section bars such as similar aluminum alloy are connected and fixed to be barricaded as the link of certain frame structure between mutually.

Background technique: at present, commercially available similar link generally adopts double hook to connect, and is with a slice Steel Spring Plate one end bifurcated therefrom, make yoke repeatedly crooked and have certain elasticity through punching press, and going out the opposite latch hook of both direction in the front end bending, the connector of this structure is because its butt hook through repeatedly crooked, can produce resiliently deformable, cause coupling mechanism force not high, in addition, this link is asymmetric two-sided contact, and coupling mechanism force is inhomogeneous, stressedly can glide when big, damage the locked object surface.

Summary of the invention: the utility model purpose is to the defective that overcomes existing link provides a kind of two-sided symmetry contact, the high difficult link that glides of coupling mechanism force.

For achieving the above object, the utility model adopts following technical solution: the latch hook of many hooks link is the flat member that the end has the side hook, the middle part is provided with axis hole, the opposition side of side hook is provided with the slope shape projection, at least be no less than that mode that four latch hook alternately arranges with side hook direction is stacked to be installed on the lock shaft movingly, bearing pin is with to be connected slide block fixedly connected and place shell inner cavity to constitute the butt hook assembly movingly, connect slide block and be installed with spring clip near latch hook afterbody place, the bayonet socket width of spring clip is not less than stacked latch hook afterbody total thickness and presss from both sides thereon, and the height of shell inner cavity is less than the spacing between two lateral processes.

Adopt many hooks link of such scheme; because its latch hook is a flat member; can adopt punching process; no material bending position can not produce the resiliently deformable phenomenon and weakens coupling mechanism force, in addition; adopt the two-sided connection that interlocks of many hooks; balanced two-sided coupling mechanism force is difficult for gliding, and is connected material thereby more effectively protected.

The utility model is described in further detail below in conjunction with accompanying drawing, and provide embodiment simultaneously.

Description of drawings:

Accompanying drawing 1 is the utility model embodiment External view;

Accompanying drawing 2 is the utility model embodiment butt hook modular construction schematic representation;

Accompanying drawing 3 is non-locking state structural representation;

Accompanying drawing 4 is the locking state structural representation.

Specific embodiment: as shown in Figure 1, the shell 5 of many hooks link is square, with alloy material through castable, be provided with vertical inner chamber in the shell 5, intracavity section also is square, the butt hook assembly comprises connection slide block 4, spring clip 6, latch hook 1 member such as grade, latch hook 1 is formed through stamping-out by sheet metal, the end stamping-out of latch hook 1 becomes to have the side hook of similar " 7 " shape, slightly rely on center at the opposition side of side hook and be provided with slope shape projection 2, slope shape projection 2 is straight on one side towards the end, the rear and front end slightly is wider than in the intermediate portion of latch hook 1, and be provided with circular shaft hole 7, be installed in movingly on the bearing pin 3 after the mode that 8 latch hooks 1 are alternately arranged with side hook direction is overlapping, connecting the slide block 4 same metallic plate punchings that adopt forms, overturning volume on the afterbody, elongated slot 8 is offered in the centre, the front end punching of elongated slot 8 goes out a baffle plate that upwarps, height is concordant with side end of reel portion, the front end that connects slide block 4 is fixedly established a spring clip 6, both sides fixedly are embedded long strip connecting plate 9, bearing pin 3 two ends are fixed on connecting plate 9 and form on the butt hook assembly, latch hook 1 afterbody is clipped in spring clip 6 bayonet sockets, the width of bayonet socket equals the folded thick of latch hook 1, whole assembly is inserted into shell 5 inner chambers from the end movingly, the height of inner chamber is less than the spacing between two lateral processes 2, the ingress is provided with the chamfering that matches with slope shape projection 2, cam 10 is equipped with the boss as camshaft, lower wall is provided with positioning round orifice on the shell 5, cam 10 places the elongated slot 8 that connects slide block 4, both sides end face cylindrical cam platform is journaled into respectively in the positioning round orifice movingly, and middle cam is with the baffle plate that is connected slide block 4 and rewind afterbody and flush, and cam 10 front boss are provided with plum blossom hole.

During use, earlier many hooks link is fixed on one of interconnective section bar of desire, expose the side hook, offer the latch hook patchhole on another section bar, the latch hook patchhole slightly is wider than the width after latch hook 1 closure, after latch hook 1 inserts in the hole, spanner is inserted plum blossom hole rotating cam 10 make and contract after connecting slide block 4, contract after driving latch hook 1, thereby internal chamber wall promotes to press in the slope shape projection 2 and opens latch hook 1 and hook section bar inwall and locking; During demolition, backward rotation cam 10 connects slide block and protracts 4, and under the folder power effect of spring clip 6, latch hook 1 closure can insert in the hole from latch hook and transfer to and separate.

Claims

1, a kind of many hooks link, comprise the shell that the cross section is rectangular, shell is provided with vertical inner chamber, the butt hook assembly that has latch hook places shell inner cavity movingly, and it is flexible by a cam mechanism driving butt hook assembly, the butt hook assembly also is provided with the latch hook open-and-close mechanism with the interlock of assembly expanding-contracting action, the assembly latch hook closure of protracting, the latch hook that contracts behind the assembly opens, it is characterized in that: described latch hook (1) has the flat member of side hook for the end, the middle part is provided with axis hole (7), the opposition side of side hook is provided with slope shape projection (2), at least the latch hook (1) that is no less than four replaces stacked being installed in movingly on the lock shaft (3) of mode of arranging with side hook direction, bearing pin (3) is with to be connected slide block (4) fixedly connected and place shell (5) inner chamber to constitute the butt hook assembly movingly, connect slide block (4) and be installed with spring clip (6) near latch hook (1) afterbody place, the bayonet socket width of spring clip (6) is not less than stacked latch hook (1) afterbody total thickness and presss from both sides thereon, and the height of shell (5) inner chamber is less than the spacing between two lateral processes (2).
