Description
Technical field
The utility model belongs to jockey technical field between Model For The Bush-axle Type Parts, is specifically related to a kind of snap joint.
Background technology
The use of tool-class article is the powerful of their functions, and the scope of application wider user more like.As screwdriver, user is often subject to the puzzlement of a word, cross and size, just can quick-replaceable driver bit if adapter is set on screwdriver, to coordinate the screw of various models; For another example existing flexible pickup, just can be replaced by if adapter is set on handle the instrument that checks the difference in functionalitys such as mirror.The kind of snap joint is at present quite a lot of, but the part comparison of extremely most snap joint is many, processing is more complicated, assembly technology is more difficult.
Utility model content
The problem existing for prior art, the purpose of this utility model is that design provides a kind of technical scheme of snap joint.
Described a kind of snap joint, it is characterized in that the connector and the socket that in the middle part of comprising, are provided with installing hole are arranged on the overcoat outside connector, described connector and outer set upper side are fixed by the jump ring circle arranging, between described connector and overcoat, be equipped with spring, described spring comprises spire and Access Division, described spire socket is arranged on connector, described Access Division clamping is arranged in the draw-in groove of connector, and described two ends, Access Division connect and coordinate with the convex tendon lower surface gear that puts setting outward.
Described a kind of snap joint, is characterized in that described installing hole is regular polygon structure.
Described a kind of snap joint, is characterized in that described connector upper end outer wall is provided with jump-ring slot, and described jump ring circle connects and coordinates with the convex tendon upper surface gear putting outward after snapping in jump-ring slot.
Described a kind of snap joint, is characterized in that described connector lower end is provided with connector seat, and described connector seat diameter is greater than connector diameter, and described connector seat connects and coordinates with spring bottom gear.
Described a kind of snap joint, is characterized in that described Access Division is structure of horizontal gear.
Described a kind of snap joint, is characterized in that described draw-in groove and the angle of center line are 30 degree.
Above-mentioned a kind of snap joint, reasonable in design, in the time that overcoat is drop-down, the Access Division of spring is left external piece and is deviate from from draw-in groove, thereby realizes the fast insert-pull of external piece; In the time that overcoat resets, the Access Division of spring enters in draw-in groove and coordinates with external piece clamping, thereby realizes the fixing of external piece.The utility model by connector and the overcoat of resilient engagement, is realized quick-replaceable external piece, and coordinates with external piece and stablize, external piece difficult drop-off in use procedure.In addition, the utlity model has part few, simple in structure, be convenient to part processing, the advantage such as assembly technical requirement is low, apply in the interconnection technique field between Model For The Bush-axle Type Parts that is adapted at.

Detailed description of the invention
Further illustrate the utility model below in conjunction with Figure of description.
As Figure 1-3, a kind of snap joint comprises connector 1 and overcoat 2.Overcoat 2 is socketed in outside connector 1, and with connector 1 resilient engagement.Connector 1 middle part is provided with installing hole 101, and installing hole 101 is for the external piece of pegging graft.The preferred structure of installing hole 101 is regular polygon hole, as regular hexagon etc., external piece can not be rotated in installing hole 101, improves stability.Connector 1 upper end outer wall is provided with jump-ring slot 102, and jump ring circle coordinates jump ring circle 3 for clamping.Connector 1 and overcoat 2 upper ends are fixing by the jump ring circle 3 arranging, and jump ring circle 3 connects and coordinates with the convex tendon 201 upper surface gears on overcoat 2 after snapping in jump-ring slot 102.
Between connector 1 and overcoat 2, pass through spring 4 resilient engagement that arrange.Spring 4 comprises spire 401 and Access Division 402, spire 401 sockets are arranged on connector 1, Access Division 402 clampings are arranged in the draw-in groove 103 of connector 1, and 402 two ends, Access Division connect and coordinate with the convex tendon 201 lower surface gears that arrange on overcoat 2, and draw-in groove 103 is 30 degree with the angle of center line.By the effect of jump ring circle 3 and spring 4 Access Divisions 402, overcoat 2 is limited on connector 1, can not come off from connector 1.As shown in Figures 4 and 5, Access Division 402 is preferably structure of horizontal gear, is laterally applied on spire 401.
In addition, in connector 1 lower end, connector seat 5 can be set, connector seat 5 diameters are greater than connector 1 diameter, and connector seat 5 connects and coordinates with spring 4 bottom gears, thus stabilizing spring 4.
As shown in Figure 6, in order to coordinate the use of snap joint, the bottom of external piece is provided with the collar coordinating with spring 4 Access Divisions 402.
When use, drop-down when overcoat 2, under the effect of overcoat 2, spring 4 Access Divisions 402 that make to be mated are simultaneously drop-down, and Access Division 402 is left the collar of external piece and deviate from from draw-in groove 103, thereby realize the fast insert-pull of external piece; When overcoat 2 resets, the Access Division 402 of spring 4 enters in draw-in groove 103 and coordinates with the collar clamping of external piece, thereby realizes the fixing of external piece.
Shown in the above and figure is only preferred embodiment of the present utility model.It should be pointed out that for the person of ordinary skill of the art, not departing under the prerequisite of the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
