Abstract

The utility model provides a buckle structure. The buckle structure comprises a buckle base and a buckle head buckled with the buckle base, a buckling space and a stop block are arranged on the buckle base, and the stop block is arranged on the buckle base through an elastic cantilever beam and can generate elastic displacement to leave a buckle head falling path. According to the scheme, the stop block is arranged on the buckle base through the cantilever beam to achieve the anti-falling function of the buckle head; when the buckle is disassembled, the stop block leaves a buckle head channel by pressing the cantilever beam down, and the buckle can be disassembled; the cantilever beam rebounds when loosened to block the buckle assembling and disassembling channel so that the buckle can be effectively prevented from falling off. The buckle structure is simple in structure and durable in use.

Description

A kind of buckle structure

Technical field

The utility model relates to field of automobile, particularly relates to a kind of for the buckle structure on automobile.

Background technique

In automotive field, the tightness of buckle and the design repeatedly can buckle departing from, very important.Fig. 1 and Fig. 2 are two kinds of conventional at present buckle understructures.The existing buckle structure of one as shown in Figure 1 comprising snap seats 100 and buckle head 200 buckle structure each other, arranges block 110 on buckle structure removal outlet 120.Block 110 is at buckle removal outlet 120 places, prevents coming off of buckle by design amount of interference, and like this in the cargo handling process of buckle, the amount of interference that all needs to overcome rigidity completes the assembling of buckle structure, and nature can have influence on efficiency of assembling.And after buckle is dismantled repeatedly, the structure of block 110 can reduce because wearing and tearing cause amount of interference, the anti-drop function of base will weaken like this.

As shown in Figure 2, snap seats 400 and buckle head 300 buckle structure each other, on buckle structure removal outlet 420, be provided with projection 410, as buckle head departed from from buckle structure removal outlet 420, need the external world to provide and can overcome projection 410 elastically-deformable power, projection 410 is carried out to reverse extrusion, allow buckle head 300 deviate from.In this kind of scheme, projection 410 is very easily wearing and tearing also.When after projection 410 wearing and tearing, snap seats 400 and buckle head 300 will very easily be divided de-, thereby cannot meet user demand.

Model utility content

The technical problems to be solved in the utility model is to provide a kind of buckle structure, causes disconnecting prevention structure amount of interference deficiency, the problem that anti-drop function weakens to overcome buckle disengaging long-term work wearing and tearing in existing snap seats.

For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of buckle structure, comprise snap seats and the buckle head with described snap seats buckle, described snap seats is provided with buckle space and block, described block is arranged in snap seats by elastic cantilever, and can produce elastic displacement leave buckle head throw off path.

Further, described buckle space comprises that main aperture and the hole in main aperture side lack, and described block blocks hole and lacks.

Further, described hole lacks and is less than buckle main aperture diameter.

Further, described overhang comprises the first cantilever, the second cantilever and overarm, and described the first cantilever is connected with overarm and snap seats respectively with the second cantilever, and described block is arranged in overarm.

The beneficial effect of technique scheme of the present utility model is as follows:

In such scheme, by adopting overhang that block is arranged in snap seats, realize the function of the Drop-proof of buckle head; When buckle handling, by pressing down overhang, block leaves buckle head passage, can dismantle buckle; Unclamp overhang, the resilience of overhang nature, blocks the passage of buckle head dismounting, can effectively stop coming off of buckle.Simple in structure, durable in use.

Embodiment

For making the technical problems to be solved in the utility model, technological scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.

As shown in Figures 3 and 4, a kind of buckle structure that the utility model embodiment provides, comprises snap seats 10, and described snap seats 10 and buckle head 20 match, and both are in conjunction with forming buckle structure.Described snap seats 10 is provided with buckle space and block 14, and described block 14 is arranged in snap seats 10 by elastic cantilever, and can produce elastic displacement and leave buckle head 20 and throw off path.

In such scheme, by adopting overhang that block 14 is arranged in snap seats 10, realize the function of the Drop-proof of buckle; When buckle handling, by pressing down overhang, block leaves buckle head 20 passages, can dismantle buckle; Unclamp overhang, the resilience of overhang nature, blocks the passage of buckle head 20 dismounting, can effectively stop coming off of buckle.

Further, described buckle space comprises that main aperture 15 and the hole in main aperture 15 sides lack 16, and described block 14 blocks hole and lacks 16.

Wherein, described hole lacks 16 and is less than buckle main aperture 15 diameters.By this design, can make snap seats 10 and buckle head 20 under buckle state, play certain position-limiting action.Can make buckle more accurately closely in conjunction with cantilever beam structure and block.

Further, described overhang comprises the first cantilever 11, the second cantilever 12 and overarm 13, and described the first cantilever 11 is connected with overarm 13 and snap seats 10 respectively with the second cantilever 12, and described block 14 is arranged in overarm 13.In the time that buckle head 20 need be deviate from from snap seats 10, press down block 14, due to the good elasticity capacity of overhang, block 14 can produce a less displacement, thereby temporarily can not block the path of deviating from of buckle head 20.After buckle head 20 is deviate from, cantilever beam structure can well recover.This structure can long-term durable use, compared to prior art, more lasting, and this structure is also uncomplicated.

The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
