Technical Field

The utility model belongs to the technical field of the engineering manufacturing, concretely relates to anti-disengaging mechanism.

Background

Big and heavy modules such as skeleton installation qianmen, back door, back lid, preceding guarantor that slide are used to whole car CUBING examine a lot of department at present, on the one hand these big and heavy modules lack self-locking mechanism when moving to work area or keeping away from work area on the skeleton that slides, when the manual work forgets locking, the automatic phenomenon of sliding can take place for the skeleton, then can take place to drop to break the module and cause economic loss lightly, then can injure personnel and take place the incident seriously, so will increase self-locking mechanism and be very important and necessary. On the other hand, when the large and heavy modules are connected to the whole vehicle CUBING gauge on the sliding framework, an automatic pre-positioning mechanism is lacked, after a pre-positioning area needs to be found manually, the sliding framework and the CUBING substrate are fixed in an inserted pin mode, then the modules are precisely positioned on the whole vehicle CUBING, the process is complicated, the operation is inconvenient, and the difficulty in manually finding the pre-positioning area is high.

SUMMERY OF THE UTILITY MODEL

In order to solve the above-mentioned problem that exists among the prior art, the utility model provides an anti-disengaging mechanism has self-locking function, moves working area when the skeleton that slides and can realize automatic locking, prevents that the module from droing to fall to destroy and hindering the personnel.

The utility model discloses a following technical scheme realizes:

an anti-drop mechanism comprises a handle 1, a support plate 2, a return spring 3, an automatic clamping arm 4, a limiting seat 5, a rotating shaft 7 and a support 8; the upper surface of one end of the automatic clamping arm 4 is provided with a groove, the lower surface of the automatic clamping arm is provided with a bulge, the bulge is positioned in the groove of the limiting seat 5, and the other end of the automatic clamping arm 4 is connected with the handle 1; the support 8 is connected with the automatic clamping arm 4 through the rotating shaft 7, the lower surface of the support plate 2 is fixed on the upper surface of the support 8, the upper surface of the support plate 2 is fixed at the bottom of the sliding trolley, the lower surface of the support plate 2 is further provided with a groove, and two ends of the reset spring 3 are respectively located in the groove in the upper surface of the automatic clamping arm 4 and the groove in the lower surface of the support plate 2.

Further, the support plate 2 is connected with the support 8 through the adjusting bolt 6.

Further, the limiting seat 5 is a slope structure with an angle at the front end, and the angle is smaller than the maximum lifting angle of the automatic clamping arm 4.

Compared with the prior art, the utility model has the advantages as follows:

the anti-drop mechanism of the utility model has self-locking function, when the sliding framework moves to the working area, the automatic locking can be realized, and the module is prevented from dropping, damaging and injuring personnel; meanwhile, the device has an automatic pre-positioning function, automatically searches for a positioning area, is quick, trouble-saving and labor-saving, and reduces the labor cost; the limit of the working position of the sliding framework on the substrate can be realized, the working position of the sliding framework on the substrate does not need to be limited by a bolt in the past, and the processing and the installation of a hole pin of the detection tool are reduced; the mechanism has universality and can be widely applied to a sliding framework mechanism of a CUBING gauge similar to a whole vehicle.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

Example 1

As shown in fig. 1, an anti-drop mechanism comprises a handle 1, a support plate 2, a return spring 3, an automatic clamp arm 4, a limiting seat 5, a rotating shaft 7 and a support 8; the upper surface of one end of the automatic clamping arm 4 is provided with a groove, the lower surface of the automatic clamping arm is provided with a bulge, the bulge is positioned in the groove of the limiting seat 5, and the other end of the automatic clamping arm 4 is connected with the handle 1; the support 8 is connected with the automatic clamping arm 4 through the rotating shaft 7, the lower surface of the support plate 2 is fixed on the upper surface of the support 8, the upper surface of the support plate 2 is fixed at the bottom of the sliding trolley, the lower surface of the support plate 2 is further provided with a groove, and two ends of the reset spring 3 are respectively located in the groove in the upper surface of the automatic clamping arm 4 and the groove in the lower surface of the support plate 2.
