Abstract
The utility model provides a kind of connection buckle with disconnecting prevention structure, comprise the buckle main body that is tabular, offer in one end of this buckle main body along the through through hole of its thickness direction, the lower surface of buckle main body is integrally formed a pair symmetrically arranged claw along the circumference of this through hole, be integrally formed the buckle wall portion forming buckle slot thereon on the surface in one end in contrast to through hole of buckle main body, this buckle wall portion in order to the card ingress forming buckle slot be integrally formed along snap-fit enter in buckle slot snap in direction extend back-off.Because the card ingress at buckle slot is integrally formed a back-off, after snap-fit snaps in, when snap-fit stress deformation, snap-fit can be withstood by this back-off, prevent snap-fit from deviating from from buckle slot, be conducive to the connection reliability improving snap-fit.
Description
Technical field
The utility model relates to a kind of connection buckle with disconnecting prevention structure.
Background technique
As shown in Figure 6, general connection buckle only has the buckle slot of a cross section substantially in " C " font, usually by the interference fit snapping in opening size and snap-fit of buckle slot self to realize anticreep, adopt this structure, when larger by external force, the clamping mechanism of buckle self will be made to be out of shape, to cause snap-fit to be deviate from, Joint failure.
Model utility content
In view of this, main purpose of the present utility model is to provide a kind of snap-fit that can effectively prevent to use buckle from connection with the connecting of disconnecting prevention structure that have of deviating from buckle.
The utility model provides a kind of connection buckle with disconnecting prevention structure, comprise the buckle main body that is tabular, offer in one end of this buckle main body along the through through hole of its thickness direction, the lower surface of described buckle main body is integrally formed a pair symmetrically arranged claw along the circumference of this through hole, the buckle wall portion forming buckle slot is integrally formed thereon on the surface in one end in contrast to described through hole of described buckle main body, being integrally formed to enter along snap-fit in order to the card ingress forming described buckle slot and snapping in the back-off that direction extends in described buckle slot in this buckle wall portion.
Adopt said structure, because the card ingress at described buckle slot is integrally formed a back-off, after snap-fit snaps in, when snap-fit stress deformation, snap-fit can be withstood by this back-off, prevent snap-fit from deviating from from buckle slot, be conducive to the connection reliability improving snap-fit.
Preferably, the cross section of described buckle wall portion on the length direction perpendicular to described buckle main body is in " C " font, and the end portion of described back-off tilts towards its lower inner side from the upper outside of the opening being somebody's turn to do " C " font.
Adopt said structure, because the end portion of described back-off tilts towards its lower inner side from the upper outside of the opening being somebody's turn to do " C " font, guiding function is played when both buckle slot being snapped in snap-fit, snap-fit can be reduced and enter operation easier in buckle slot, be conducive to again improving the Anti-extrusion effect of described back-off to snap-fit.
Preferably, described buckle wall portion is formed in the two ends of described " C " font and extends and a pair that is oppositely arranged projection along described buckle principal length direction, described back-off is connected with one of them projection.
Adopt said structure, can better snap-fit is limited in buckle slot by described a pair projection, certain inhibition be played to snap-fit and deviates from from buckle slot to prevent it.
Preferably, described snap-fit is the parts bending rectangular shape, and its horizontal component snaps in described buckle slot, and its vertical portion runs through described through hole and is clamped between described a pair claw.
Adopt said structure, connection buckle can be fixed on (metope, equipment) on mounting object by described a pair claw.

Embodiment
Referring to Fig. 1 ~ 5, the embodiment with the connection buckle of disconnecting prevention structure described in the utility model is described in detail.In following description, described left and right all refers to left and right above-below direction corresponding in Fig. 1 ~ Fig. 3 up and down.
As shown in FIG. 1 to 3, connection buckle described in the utility model comprises the buckle main body 1 that is tabular, one is offered along the through hole 2 of the through circle of its thickness direction in the right part of this buckle main body 1, the lower surface of buckle main body 1 is formed with a pair claw 3 along the circumference of this through hole 2, and this pair claw 3 is arranged around the symmetrical interval of through hole 2.A buckle slot 4 is integrally formed thereon on the surface in the left part (namely in contrast to one end of described through hole 2) of buckle main body 1, this buckle slot 4 entirety for two ends, left and right are through and front side is formed with " C " font of opening, that is is being " C " font in order to the buckle wall portion 41 forming buckle slot 4 perpendicular to the cross section on left and right directions (i.e. the length direction of buckle main body 1).Buckle wall portion 41 is formed in the two ends of " C " font the projection 42 of pair of opposing, and as shown in Figure 4, this pair projection 42 is along the extension of buckle main body 1 length direction and cross section is semicircular bar-like member.
As shown in Figure 1 to 4, a back-off 43 is integrally formed in order to front openings (that is buckle slot 4 the snap in mouth) place forming buckle slot 4 in buckle wall portion 41, the direction that snaps in that this back-off 43 enters in buckle slot 4 along snap-fit 5 extends, further, the end portion of this back-off 43 tilts towards its lower inner side from the upper outside of aforementioned front openings.In the present embodiment, back-off 43 is formed at the side, upper end portion of " C " font buckle slot 4, and this back-off 43 to be formed by integral forming process with the projection 42 being positioned at upside and is connected.The above-mentioned described connection buckle with disconnecting prevention structure can adopt PP plastics or PE plastics to be prepared from, or other plastic extruding formings also can be adopted to process.This connection buckle with disconnecting prevention structure is generally applied to motor vehicles for civilian use, machinery, field of household appliances.
In using process, the mounting object (metope, equipment) of connection buckle is offered mounting hole that round diameter that an aperture surrounds than aforementioned a pair claw 3 is slightly little usually, and connection buckle snaps in this mounting hole internal fixtion on mounting object by this pair claw 3.In the present embodiment, snap-fit 5 is the parts bending rectangular shape, and its vertical portion runs through through hole 2 and is clamped between aforementioned a pair claw 3, and its horizontal component snaps in buckle slot 4 via the front openings of buckle slot 4.
Because front openings (that is buckle slot 4 the snap in mouth) place at buckle slot 4 is integrally formed a back-off 43, after snap-fit 5 snaps in, when snap-fit 5 stress deformation, snap-fit 5 can be withstood by this back-off 43, prevent snap-fit 5 from deviating from from buckle slot 4, be conducive to the connection reliability improving snap-fit 5.In addition, by once-through operation, operator ensure that snap-fit normally snaps in buckle slot, do not need to increase operating procedure, this connection buckle with disconnecting prevention structure also have manufacture simple, the advantages such as convenient, price is lower are installed.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Such as, in the present embodiment, back-off 43 is formed at the side, upper end portion of " C " font buckle slot 4, and back-off 43 is one-body molded with the projection 42 being positioned at upside; But not limited thereto, this back-off also can be formed at the side, underpart of " C " font buckle slot.
