Abstract
The utility model relates to an adjustable lock catch, comprising a lock hook, a retaining ring, a bottom plate, a lock nose fixedly connected with the bottom plate, and a wrench frame, wherein the lock nose is provided with a lock hole. The adjustable lock catch is characterized in that the bottom plate is provided with a hinged support; the wrench frame is hinged on the hinged support in furcation shape; a hinge pin is assembled between furcation bodies of the wrench frame; and a draw bar is fixedly connected on the retaining ring and is in threaded connection with the hinge pin. By adopting the threaded advancing and retreating between the draw bar and the hinged pin, the connection length between the retaining ring and the lock hook can be adjusted conveniently; and the retaining ring and the lock hook are in rigid connection, thus being small in connection clearance and firm in connection under the connection state. The adjustable lock catch is provided with few parts, and is simple in structure and low in cost.
Description
Technical field
The utility model relates to a kind of snap fasteners, the especially a kind of adjustable snap close that can adjust the coupling mechanism force that connects object.
Background technology
We know, the connection of sheet metal component or the case lid of hinged folding are that snap close connects with what adopt connecting of casing.It is the rigid connection that adopts between latch hook and the lock nose that this snap close connects major part, and the fitting allowance between latch hook and the lock nose is little, and therefore, its syndeton length requires comparatively strict.Generate the connection gap owing to the object that connects in use easily produces deformation, cause connecting insecure.Numerous for this reason technician have invented and can regulate the snap close that connects angle and length automatically.For example, on August 13rd, 2003 notice of authorization CN2565922Y China utility model patent manual in disclosed " a kind of Spring lock catch ", it comprises hook, base and the hanging nose that connects with base, respectively be provided with pin shaft hole on the dual-side of base, one bearing pin is housed between two pin shaft holes, hanger is housed on the bearing pin, hanging nose is coupling on hanger, between the rearward end of base and bearing pin, spring is housed, on the bottom surface of base, is provided with installing hole.Its connection of above-mentioned disclosed elastic lock is resilient connection, and it can exist elasticity under coupled situation loosening, and the elastic lock of this structure is applied in and will adopts on the sheet metal component that prevents to move mounting article, can exist to connect illusive deficiency.
Summary of the invention
To exist elasticity loosening and exist and connect illusive deficiency in order to overcome in the prior art elastic lock, the utility model provide a kind of simple in structure, cost is low, easy to operate, connect firm adjustable snap close.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of adjustable snap close, it comprises a lock nose and a spanner frame that a latch hook, a clasp, a base plate, are fixedlyed connected with base plate, have lockhole on the described lock nose, it is characterized in that: described base plate is provided with free bearing, described spanner frame is fork-shaped and is hinged on the free bearing, assembling one bearing pin between the fork-shaped support body of spanner frame, the fixedly connected pull bar of described clasp, this pull bar is threaded with described bearing pin.
After adopting technique scheme, the beneficial effect that the utility model reaches is: pull bar fixedly connected on the clasp is threaded with bearing pin, and the screw thread advance and retreat between rotating rod realization and the bearing pin then can be adjusted the syndeton length between clasp and the latch hook easily; Connecting between clasp and the latch hook is rigid connection, and it is little that it connects gap under the coupled situation, and it is firm to connect.The utility model used unit is few, and is simple in structure, and cost is low, handling ease.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further.
Accompanying drawing is a kind of structural perspective of the present utility model.
Among the figure: 1. latch hook, 2. clasp, 3. pull bar, 4. free bearing, 5. bearing pin, 6. spanner frame, 7. lock nose, 8. seat board, 9. lockhole.
The specific embodiment
In the accompanying drawings, a kind of adjustable snap close, it comprises a latch hook 1, a clasp 2, a base plate 8, a lock nose 7 and a spanner frame 6.
As shown in drawings, can be that welding is fixing between lock nose 7 and the base plate 8, also can adopt lock nose 7 and base plate 8 integrated punchings to be shaped.What present embodiment preferentially adopted is the technical scheme that lock nose 7 and base plate 8 integrated punchings are shaped.Have lockhole 9 on the lock nose 7.
At base plate 8 integrated punchings one free bearing 4 is arranged.
In the accompanying drawings, spanner frame 6 is pronged shape, is hinged on the free bearing 4 by hinge.Spanner frame 6 can cooperate locking with lock nose 7 when it is in final position around the hinge reciprocally swinging.
As shown in drawings, assembling one bearing pin 5 between the fork-shaped support body of spanner frame 6.
In the accompanying drawings, clasp 2 fixedly connected pull bars 3, this pull bar 3 is realized being threaded with bearing pin 5.
During use, latch hook 1 is fixed on first mounting article, and base plate 8 is fixed on second mounting article, rotating rod 3 by and bearing pin 5 between screw thread advance and retreat, adjust the syndeton length between clasp 2 and the bearing pin 5 easily; To snap close 1 direction rotating spanner frame 6, clasp 2 is fastened on the latch hook 1, counter-rotation spanner frame 6 is to final position then again, and spanner frame 6 cooperates by other latch fitting lockings with lock nose 7.Connecting between the wherein clasp 2 and latch hook 1 tension locking, clasp 2 and latch hook 1 is rigid connection, and its connection gap is little under the coupled situation, and it is firm to connect.
