Description

Flexible fixing device for attitude measurement

Technical Field

The utility model relates to a fixing device, in particular to an auxiliary structure fixing device for attitude measurement of a pointed object.

Background

The target point is a special visual mark for marking the key part of the moving object, is used for the calibration of a camera and the motion analysis of the object, and is generally pasted on the key point for expressing the motion mode. Most of the optical measurement of the rolling attitude at the present stage is directed at the end face of the object, and a plate with certain rigidity is directly fixed on the end face of the object by an adhesion method, and then a target point is adhered on the fixing plate. But the fixed plate can not be pasted on the object tip, so the fixation of the tip rolling attitude measurement target point can not be solved, and the fixed plate is easy to fall off due to the falling collision of the tip object, so the fixed plate needs to be bonded again before each measurement, which is time-consuming and labor-consuming.

Disclosure of Invention

The technical problems solved by the utility model are as follows: an auxiliary structure fixing device for attitude measurement of a pointed object is provided, and fixing reliability is improved.

The technical scheme of the utility model is as follows: a flexible fixation device, the environment of use of the device being: is fixed on the tip part of the object;

the device comprises a clamp and a pull rope, wherein the clamp is fixed to the tip part, one end of the pull rope is fixed to the clamp, and the other end of the pull rope is fixed to an object. This technical scheme provides a flexible fixing device for gesture measurement, and this fixing device not only can solve the target point fixed problem that is used for sharp object roll-over gesture to measure, and the installation is firm moreover, and the erection dimension is adjustable, but also is applicable to the object that the terminal surface is arbitrary curved surface.

Preferably, the pull ropes are symmetrically arranged. This technical scheme further discloses the arrangement of stay cord has guaranteed the fixed reliability of installation.

Preferably, one end of the pull rope is fixed on the object through a suction cup. This technical scheme specifically discloses the fixed mode of stay cord and object, and structural style is simple, convenient to detach, installation.

Preferably, a plate is further fixed on the clamp, and a mark point is arranged on the plate. The technical scheme further discloses other structures attached to the device, and the application environment of the whole device is expanded.

Preferably, the plates are positioned at the left side and the right side of the object, and the plate at each side is provided with a mark point. The technical scheme further discloses the arrangement mode of the plates, and a structural foundation is laid for realizing certain application environment functions.

Preferably, the device is particularly suitable for measuring the attitude of an object. The technical scheme further discloses an application environment of the device, and in the scene, the technical scheme can effectively ensure the effect of attitude measurement.

Preferably, said tip portion comprises a conical surface. The technical scheme further discloses a structural form of the object tip part, and the application objects are wide.

Drawings

Fig. 1 is a schematic view of an installation state of the embodiment of the present invention.

Detailed Description

As shown in fig. 1, the object on which the flexible fixture of this embodiment is mounted has a pointed portion, which in this embodiment includes a conical surface, as shown on the right side of the object. The device include sucking disc 1, stay cord 2, clamp 3 and board 4, board 4 fix on clamp 3. During installation, the hoop 3 is sleeved on the conical surface and is fixed and clamped. After the hoop 3 is sleeved on the conical surface, the plates 4 are positioned at the left side and the right side of the axis of the object and extend outwards. In order to further ensure the effect of fixed installation, the device also comprises a pull rope 2, one end of the pull rope 2 is fixed on the hoop 3, and the other end is fixedly connected with the sucker 1. After the pull rope 2 is tensioned, the sucking disc is fixedly arranged on the outer surface of an object, and the trend that the hoop 3 moves outwards along the axial direction is further restrained. The pull ropes 2 comprise a plurality of ropes which are symmetrically arranged on the circumference of the object in pairs.

The device of the technical scheme is particularly suitable for measuring the posture of a moving object, and the plate is provided with mark points for calibrating a camera and analyzing the motion of the object. In the application environment, the fixing device can adapt to the requirements of the structural form of the object.
