Description

Target ball anti-falling bracelet

Technical Field

The utility model relates to a protection setting of optical measurement instrument, concretely relates to target ball prevents falling bracelet.

Background

In the field of precision measurement, the laser interferometry is an effective technical means for ultra-precision measurement due to the advantages of non-contact, high precision, traceability and the like, and is widely applied to precision measurement occasions of static geometric quantities such as gauge verification, lathe calibration, nano sensor calibration and the like. Many measuring instruments based on laser interferometry (such as laser interferometers and laser trackers) need to be matched with a reflecting prism, and a spherical reflector is generally adopted for a reflecting mirror of a tracker with a tracking function, and the centroid of the spherical reflector coincides with the optical center of the spherical reflector.

The laser tracker needs the cooperation of target ball in the measurement process, if the motion of certain point of real-time tracking, still need adsorb the position of paying attention to with the magnetism ball seat, then adsorbs the target ball in the positioning groove of ball seat, realizes the target ball and is surveyed the fixed of position. However, in the process of taking the target ball, the situation that the hand is not good to hold due to the body type problem of the target ball and the characteristic that the material is smooth and easy to slip exists, so that the situation that the target ball accidentally falls off can be caused, and the instrument is broken. In the prior art, the target ball is made of an anti-falling material, but the possibility of being broken by falling cannot be avoided.

SUMMERY OF THE UTILITY MODEL

The utility model provides a target ball that prior art exists can unexpected the problem that drops in the use.

The utility model discloses a following technical scheme realizes:

the utility model provides a target ball prevents falling bracelet, includes target ball cap, haulage rope and bracelet, have the through-hole on the target ball cap, haulage rope one end is passed through the through-hole and is connected with the target ball cap, has a connecting ring on the bracelet, and the other end of haulage rope is connected with the annular ring of the go-between on the bracelet.

In order to enable the target ball cap to be matched with the target ball handheld cap, a threaded part is arranged to be matched with the internal threads of the handheld cap; the outer side of the cap head is provided with a protruding circle which corresponds to a protruding circle arranged on the inner side of the cap body on the handheld cap, so that the target ball and the anti-falling bracelet can be more firmly fixed by the design, and the target ball and the anti-falling bracelet are prevented from being separated; the haulage rope plays a connection effect between target ball cap and bracelet. Therefore, the target ball is limited by the traction rope and the hand ring, so that the target ball cannot easily fall to the ground.

The target ball cap is divided into a cap head and a threaded part, the cap head and the threaded part are both hollow cylindrical, the diameter of the cap head is larger than that of the threaded part, and a groove is formed in the outer side of the cap head.

The through hole of the target ball cap is arranged on the side surface of the cap head.

The threaded portion of the target ball cap mates with a hand cap on the target ball,

the handheld cap comprises a handheld cap threaded part and a cap body, wherein threads are arranged on the inner side and the outer side of the handheld cap threaded part, the inner side threads are matched with the threaded part of the target ball cap, the outer side threads are matched with the embedded sleeve on the target ball, and a protruding circle is arranged on the inner side of the cap body and corresponds to the protruding circle on the outer side of the cap head of the target ball cap.

The diameter of the rope end of the part of the traction rope connected with the target ball cap is smaller than that of the through hole in the cap head, so that the traction rope can conveniently penetrate through the through hole.

The haulage rope material is the fibre, durable.

The length of the traction rope is 10-20 cm, so that the target ball is prevented from falling to the ground due to the fact that the distance from the ground to the ground is short and the rope is long.

The material of bracelet is the latex, can provide a comfort for the wrist, can not cause the injury for the wrist.

Go-between on the bracelet is 8 word rings, is equipped with the pivot between two rings of 8 word rings, can rotate at will, prevents that the rope from knoing.

The bracelet is buckled with the ring between the 8-shaped rings.

Compared with the prior art, the utility model, following advantage and beneficial effect have: the target ball cap of the utility model is connected with a hand ring through the connecting rope, and the target ball is limited through the hand ring and the traction rope, so that the target ball can not easily fall to the ground to cause damage, and the condition that the target ball accidentally falls is effectively solved; and set up the axis of rotation in the 8 word rings that set up between haulage rope and the bracelet, can 360 degrees rotations not twine, prevented the condition that the rope was knoed, improved the practicality.
