Detailed description of the invention
Below embodiment of the present utility model is described in detail:
As Figure 1-3, a kind of snap component, including pin thread 100 and box 200.Pin thread 100 includes connection-peg 110；Box 200 includes insertion tube 210.Insertion tube 210 is provided with the slot 211 that the peripheral shape with connection-peg 110 coordinates and the entrance 212 connected with slot 211.The width of slot 211 is along being gradually reduced away from entrance 212 direction, and the wall thickness of insertion tube 210 is along being gradually increased away from entrance 212 direction.Insertion tube 210 and connection-peg 110 are snapped fit attachment by snap device.Owing to the width of slot 211 is gradually reduced along the direction away from entrance 212, slot 211 is made to form a downward directed cavity, be conducive to connection-peg 110 to be slipped into slot 211 bottom smoothly, reduce the pressure formed between connection-peg 110 and insertion tube 210 in insertion process.Simultaneously, when connection-peg 110 is downwardly into slot 211, owing to the distribution of force of insertion tube 210 is to be gradually increased along the direction away from entrance 212, thus be designed to the wall thickness of insertion tube 210 be gradually increased along the direction away from entrance 212, namely the structure that narrower lower end, upper end is generous, be conducive to improving the intensity of insertion tube 210, improve the service life of snap component so that snap component reaches reusable effect.
In the present embodiment, snap device includes being positioned on connection-peg 110 the first flange 111 and recessed draw-in groove 213 on the inwall of insertion tube 210.By the first flange 111 and draw-in groove 213 interference fit so that connection-peg 110 and insertion tube 210 are clasped, reach to be easily inserted or extract the purpose of pin thread.This utility model arranges draw-in groove 213 also dependent on being actually needed on connection-peg 110, correspondingly arranges matched projection on the inwall of insertion tube 210.
Draw-in groove 213 is positioned at insertion tube 210 one end away from entrance 212, is namely positioned at the bottom of insertion tube 2102.Because the bottom width of insertion tube 210 is maximum, draw-in groove 213 is located at this position and is conducive to strengthening the intensity fastening position.
Slot 211 includes the first slot 2111 and the second slot 2112 being sequentially communicated up and down, and the first slot 2111 connects with entrance 212.The width of the first slot 2111 and the width of the second slot 2112 are gradually reduced each along the direction away from entrance 212.Again because the horizontal tilt angle of the first slot 2111 is more than the horizontal tilt angle of the second slot 2112 so that the inwall of the first slot 2112 and the inwall of the second slot 2112 cooperatively form a concave corner part α.Connection-peg 110 is provided with the second flange 112 coordinated with concave corner part α.Thus this utility model is on the basis of the first above-mentioned flange 111 and draw-in groove 213 snap-fit engagement, again through coordinating of the second flange 112 and concave corner part α, strengthen the snap-fit engagement of connection-peg 110 and slot 211 further so that pin thread 100 and box 200 stable connection, reach preferably anticreep effect.
In the present embodiment, the insertion end of connection-peg 110 is arranged with cavity 113, and offers the breach 114 connected with cavity 113.Make connection-peg 110 have certain elasticity, can shrink under stressing conditions, be conducive to stretching into slot 211, reduce and stretch into stress in process.
Pin thread 100 also includes the first basal disc 120 supporting connection-peg 110.Connection-peg 110 is fixed on the first basal disc 120 away from its one end inserting end.Make pin thread 100 insert box 200 by pressing the first basal disc 120, reach the effect of convenience pressure.Connection-peg 110 is also arranged with snap ring 115 near the side of the first basal disc 120, it is simple to be connected together with thing to be fixed.
Box 200 also includes the second basal disc 220 supporting insertion tube 210.Insertion tube 210 is fixed on the second basal disc 220 away from one end of entrance 212.Facilitate box 200 fixing steadily, stress equalization.The outer wall of insertion tube 210 is near the side of the second basal disc 220 in the conical surface shape expanded gradually towards the second basal disc 220, and it is cylinder shape near the side of entrance 212.The conical surface diameter of lower section, more than the cylinder diameter of top, is conducive to that thing to be fixed is sheathed on cylinder upper limit and fixes.
In the present embodiment, this utility model also includes connector (accompanying drawing does not identify), and connector one end is connected with box 200, the other end is connected with pin thread 100 so that pin thread 100 and box 200 link together, and forms integral type gang configuration, convenient use, simultaneously facilitates and forms a complete production network.
Each technical characteristic of above example can combine arbitrarily, for making description succinct, all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics is absent from contradiction, all it is considered to be the scope that this specification is recorded.
Above example only have expressed several embodiments of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
