Description
Technical field
The invention belongs to jockey technical field between Model For The Bush-axle Type Parts, be 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, just can quick-replaceable driver bit if arrange adapter on screwdriver often by the puzzlement of a word, cross and size, to coordinate the screw of various model; For another example existing flexible pickup, if arrange adapter just can be replaced by the instrument checking the difference in functionalitys such as mirror on handle.The kind of current snap joint is quite a lot of, but the part comparison of the snap joint of extreme portions is many, processing is more complicated, assembly technology is more difficult.
Summary of the invention
For prior art Problems existing, the object of the invention is to design the technical scheme that a kind of snap joint is provided.
Described a kind of snap joint, it is characterized in that comprising middle part to be provided with the connector of installing hole and socket and to be arranged on overcoat outside connector, described connector and outer set upper side are fixed by the jump ring circle arranged, spring is equipped with between described connector and overcoat, 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 keep off connecing with the convex tendon lower surface putting setting outward and coordinate.
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, keeps off connecing coordinating after described jump ring circle snaps in jump-ring slot with the convex tendon upper surface put outward.
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 keeps off connecing with spring bottom and coordinates.
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 the angle of described draw-in groove and center line is 30 degree.
Above-mentioned a kind of snap joint, reasonable in design, when overcoat is drop-down, the Access Division of spring is left external piece and is deviate from from draw-in groove, thus realizes the fast insert-pull of external piece; When overcoat resets, the Access Division of spring enter in draw-in groove with external piece snap-fit engagement, thus realize the fixing of external piece.The present invention passes through connector and the overcoat of resilient engagement, realizes quick-replaceable external piece, and coordinates stable with external piece, external piece difficult drop-off in use procedure.In addition, it is few that the present invention has part, and structure is simple, and be convenient to part processing, the advantages such as assembly technical requirement is low, the interconnection technique field between Model For The Bush-axle Type Parts that is adapted at is applied.

Detailed description of the invention
The present invention is further illustrated 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.Be provided with installing hole 101 in the middle part of connector 1, installing hole 101 is for grafting external piece.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 is used for snap-fit engagement jump ring circle 3.Connector 1 and overcoat 2 upper end are fixed by the jump ring circle 3 arranged, and keep off connecing coordinating after jump ring circle 3 snaps in jump-ring slot 102 with convex tendon 201 upper surface on overcoat 2.
Spring 4 resilient engagement by arranging between connector 1 and overcoat 2.Spring 4 comprises spire 401 and Access Division 402, spire 401 socket is arranged on connector 1, Access Division 402 clamping is arranged in the draw-in groove 103 of connector 1, and two ends, Access Division 402 keep off connecing with convex tendon 201 lower surface that overcoat 2 is arranged and coordinate, 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 Division 402, overcoat 2 is limited on connector 1, can not comes 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, can arrange connector seat 5 in connector 1 lower end, connector seat 5 diameter is greater than connector 1 diameter, and connector seat 5 coordinates with keeping off connecing bottom spring 4, 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 coordinated with spring 4 Access Division 402.
During use, when overcoat 2 is drop-down, under the effect of overcoat 2, make spring 4 Access Division 402 that is mated simultaneously drop-down, the collar that external piece is left in Access Division 402 is deviate from from draw-in groove 103, thus realizes the fast insert-pull of external piece; When overcoat 2 resets, the Access Division 402 of spring 4 enters the collar snap-fit engagement with external piece in draw-in groove 103, thus realizes the fixing of external piece.
Shown in the above and figure is only the preferred embodiment of the present invention.It should be pointed out that for the person of ordinary skill of the art, under the premise without departing from the principles of the invention, can also make some modification and improvement, these also should be considered as belonging to protection scope of the present invention.
