Utility model content

The technical problems to be solved in the utility model there is provided it is a kind of anti-can drop, and can improve stress intensity guarantor The dangerous anti-fall mechanism of thick stick.

The technical solution of the utility model is as follows：

A kind of anti-fall mechanism of bumper, including front bumper and collision prevention girders, two are arranged with the front bumper upper end The extension that Duan Shuiping extends back, is equipped with two cuttings in the lower surface of two extensions, the collision prevention girders it is upper The opening position of corresponding two cuttings in end face is equipped with the cutting plugged and fixed of jack, the jack and corresponding end；In the preceding guarantor At least one stage clip is additionally provided with the inwall of dangerous thick stick, the opening position that the collision prevention girders correspond at least one stage clip is equipped with positioning Hole, the inwall of one end of at least one stage clip with front bumper correspondence position are fixedly connected, the other end with corresponding position The bottom hole for putting positioning hole abuts.

Using above structure, when cutting is plugged in jack, extension can also be affiliated in the upper surface of collision prevention girders, It can prevent front bumper from dropping when installation；Meanwhile stage clip one end is fixedly connected with the inwall of front bumper, the other end is with determining The bottom hole in position hole abuts, and because collision prevention girders are provided with jack, the stress of internal structure is affected, and stage clip can not only The stress of cushion bumper beam, moreover it is possible to the stress intensity of scattered collision prevention girders, it is simple and compact for structure, it is easy to process, simple operation.

For the ease of assembling, preferably, the end face of the cutting inserted terminal is set for fillet.

For the ease of dismounting, preferably, the positioning hole is wide to the bar hole of setting, the aperture of the positioning hole vertically Degree is adapted with the diameter of stage clip；The length one of height and cutting between the hole wall of the stage clip upper surface and positioning hole upper end Cause.

For the ease of processing, preferably, the front bumper, extension and cutting are made up of injection moulding integrated molding.

For the ease of processing, preferably, the collision prevention girders and positioning hole are integrally formed for punching press and are made.

Beneficial effect：The utility model prevents front bumper from dropping using the connection of cutting and jack, and is delayed using stage clip Stress is rushed, improves collision prevention girders stress intensity, simple and compact for structure, simple operation is safe.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is Fig. 1 A direction views.

Embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Fig. 1 and Fig. 2, the utility model is made up of front bumper 1 and collision prevention girders 2 etc., on the front bumper 1 End is arranged with the extension 11 that two sections of levels extend back, and two cuttings are equipped with the lower surface of two extensions 11 12, the opening position of corresponding two cuttings 12 in upper surface of the collision prevention girders 2 is equipped with jack 21, the jack 21 and corresponding end The plugged and fixed of cutting 12, the end face of the inserted terminal of cutting 12 are set for fillet.

Four stage clips 13, the position of corresponding four stage clips 13 of the collision prevention girders 2 are additionally provided with the inwall of the front bumper 1 The place of putting is equipped with positioning hole 22, and the inwall of one end of four stage clips 13 with the correspondence position of front bumper 1 is fixedly connected, separately Bottom hole of the one end with correspondence position positioning hole 22 abuts；The positioning hole 22 is vertically to the bar hole of setting, the positioning hole 22 aperture width is adapted with the diameter of stage clip 13；Height between the upper surface of stage clip 13 and the upper end hole wall of positioning hole 22 It is consistent with the length of cutting 12.

The front bumper 1, extension 11 and cutting 12 are made up of injection moulding integrated molding；The collision prevention girders 2 and positioning hole 22 be that punching press is integrally formed and is made.

Application method of the present utility model is as follows：

As shown in Fig. 1 to Fig. 2, when cutting 12 is plugged in jack 21, extension 11 can also be affiliated in collision prevention girders 2 Upper surface, it can prevent front bumper 1 from dropping when installation, then, 1 left and right both ends of front bumper and the wing of corresponding end Daughter board (not indicating) connects and fixes；Meanwhile the one end of stage clip 13 is fixedly connected with the inwall of front bumper 2, the other end and positioning hole 22 bottom hole abuts, and because collision prevention girders 2 are provided with jack 21, the stress of internal structure is affected, and stage clip 13 is not It is only capable of the stress of cushion bumper beam 2, moreover it is possible to the stress intensity of scattered collision prevention girders 2.

When changeing, first unclamp 1 left and right both ends of front bumper and be connected with the clamping of corresponding end beater or beat-up, now, extension 11 It is affiliated to and is plugged in the upper surface of collision prevention girders 2, cutting 12 in jack 21, front bumper 1 will not drops；Then, before being lifted up Bumper 1, stage clip 13 move up along the positioning hole of bar shaped, drive cutting 12 to leave jack 21, due to the upper surface of stage clip 13 Height between the upper end hole wall of positioning hole 22 is consistent with the length of cutting 12, when stage clip 13 abuts to the hole of the upper end of positioning hole 22 During wall, cutting 12 just can be removed at jack 21, remove front bumper 1；When installing again, stage clip 13 is aligned and stretches into corresponding position The positioning hole 22 put, and cutting 12 is directed at the jack 21 of corresponding end, move down front bumper 1, after grafting in place, then preceding guarantor The beater or beat-up clamping connection of dangerous 1 left and right both ends of thick stick and corresponding end.

It is simple and compact for structure, it is easy to process, simple operation.

The non-description section of the utility model is consistent with prior art, and therefore not to repeat here.

Embodiment of the present utility model is these are only, not thereby limits the scope of the claims of the present utility model, every profit The equivalent structure made with the utility model specification and accompanying drawing content, directly or indirectly it is used in other related technology necks Domain, similarly within scope of patent protection of the present utility model.
