The shortcoming of prior art in view of the above, the purpose of this utility model is to provide one to be applicable to automobile interior exterior decorations plastics The anti-buckle dropping structure of part, is used for solving anti-drop structure complexity, production cost height, structural instability etc. in prior art and asks Topic.

For achieving the above object and other relevant purposes, this utility model provides a kind of anti-sticking being applicable to automobile interior exterior decorations working of plastics Button dropping structure, including buckle and for installing the snap seats of this buckle, described snap seats is provided with chuck, and described card is buckled Being equipped with petal, form the mounting groove that coordinates with chuck between bottom and the petal of described buckle, described snap seats is by sidewall and front Wall encloses and forms, and the top edge of described antetheca is less than the bottom of described buckle, and described chuck is positioned at the upper end of described sidewall, described Antetheca is provided with and can produce elastically-deformable block, described in snap through bottom down pressure block enter chuck, described block resilience keep off Live buckle lower end, limit buckle and depart from snap seats.

Further, being provided with crossbeam between described sidewall and antetheca, described crossbeam is provided with for supporting the bracer bottom buckle.

Further, described chuck is provided with main aperture and hole lacks, and snaps through down pressure block access aperture and lacks, enters back into main aperture.

Further, the front end of described block has projection upwards, described in snap through down pressure protrude out into or leave chuck.

Preferably, the one side described projection being blocked buckle is perpendicular.

Preferably, the upper surface of described projection is curved.

Preferably, the upper surface of described projection gradually rises along the direction snapped into.

As it has been described above, the anti-buckle dropping structure being applicable to automobile interior exterior decorations working of plastics of the present utility model, there is following useful effect Really: snap seats of the present utility model is formed a whole by antetheca and sidewall, the block on antetheca, sidewall and antetheca passes through mould Having one-body molded, it is easy to manufacture, production efficiency is high, and buckle is played good position-limiting action, snaps through down and press by block Block quick assembling or dismounting, simple in construction, durable in use, use simple, low cost.

Detailed description of the invention

By particular specific embodiment, embodiment of the present utility model being described below, those skilled in the art can be by this specification Disclosed content understands other advantages of the present utility model and effect easily.

In order to describe this utility model in detail, next the automobile interior exterior decorations working of plastics that is applicable to of the present utility model is prevented Buckle dropping structure illustrates:

As shown in Figure 1-Figure 3, a kind of anti-buckle dropping structure being applicable to automobile interior exterior decorations working of plastics, including buckle 1 and use In the snap seats 2 of this buckle 1 of installation, snap seats 2 is provided with chuck 22, and buckle 1 is equipped with petal 6, the end of buckle 1 Forming the mounting groove coordinated with chuck 22 between portion and petal 6, buckle 1 is arranged on the chuck of snap seats 2 by this mounting groove On 22, snap seats 2 is enclosed formed by sidewall 20 and antetheca 21, and it is one-body molded that this structure makes snap seats 2 can pass through mould, Rapid processing, production efficiency is high, and in the present embodiment, sidewall 20 and antetheca 21 enclose formation cylinder, and the cross section of this cylinder is Square, the top edge of antetheca 21 is less than the bottom of buckle 1, and chuck 22 is positioned at the upper end of sidewall 20, and antetheca 21 is provided with can Producing elastically-deformable block 3, buckle 1 presses block 3 to enter chuck 22 by under bottom, and block 3 resilience blocks buckle 1 time End, limits buckle 1 and departs from snap seats 2.

Being provided with crossbeam 23 between sidewall 20 and antetheca 21, crossbeam 23 is provided with for supporting the bracer 24 bottom buckle 1, Prop up bracer 24 and play the effect that auxiliary supports, improve structural strength, it is to avoid buckle 1 loosens.

Chuck 22 is provided with main aperture 5 and hole lacks 4, and buckle 1 lacks 4 by pressure block 3 access aperture down, enters back into main aperture 5.Give The pressure that block 3 is downward, the projection 31 of block 3 do not goes out due to pressure transmission, and produces plastic deformation, and buckle 1 enters completely After entering main aperture 5, block 3 no longer stress, resile, block 3 blocks the sidewall of buckle 1, and buckle 1 is played spacing work With.

The front end of block 3 has projection 31 upwards, and buckle 1 plays 31 entrance by lower belling or leaves chuck 22.Protruding 31 Easily produce elastic deformation so that the installation or removal of buckle 1 are quick and convenient.

In the present embodiment, the one side blocking buckle 1 on protruding 31 is perpendicular, is conducive to carrying out spacing to buckle 1, plays Good barrier effect.

Preferably, the upper surface of protruding 31 is curved, and the beneficially bottom of buckle 1 moves forward while lower belling plays 31, Frictional force between reducing bottom projection 31 and buckle 1.

Preferably, the direction that the upper surface of protruding 31 enters along buckle 1 gradually rises so that protruding 31 and buckle 1 bottom it Between frictional force be obviously reduced, the beneficially assembling of buckle 1.

Work process of the present utility model is as follows: when installing buckle 1, produce pressing block 3, block 3 under the bottom of buckle 1 downwards Raw elastic deformation so that buckle 1 can pass through hole and lack 4 entrance main apertures 5, after buckle 1 is completely into main aperture 5, buckle 1 Bottom depart from block 3, block 3 upwards recovers deformation, higher than the bottom surface of buckle 1, blocks the sidewall of buckle 1, plays Good position-limiting action, under block 3 is not affected by external force in the case of pressure, the vibrations in vanning, transportation do not result in card Button 1 comes off from snap seats 2.When needs dismounting buckle 1, lower pressure block 3 is topmost less than the bottom surface of buckle 1 to it, Block 3 is i.e. pushed down in the bottom of buckle 1, removes from snap seats 2.

In sum, this utility model is primarily adapted for use in the interior exterior trim working of plastics of automobile, and A, B, C post, door including automobile protect Plate etc., this utility model stabilized structure, effectively prevent to be buckled in vanning, transportation and come off, snap seats can pass through mould One-body molded, it is easy to processing and manufacturing, production cost is low, and production efficiency is high.

Above-described embodiment only illustrative principle of the present utility model and effect thereof, not for limiting this utility model.Any Above-described embodiment all can be modified under spirit and the scope of the present utility model or change by those skilled in the art. Therefore, such as art has usually intellectual without departing from the spirit disclosed in this utility model with under technological thought All equivalences completed are modified or change, and must be contained by claim of the present utility model.
