Detailed Description

In order to make the utility model realize that technical means, creation characteristics, achievement purpose and effect are clearer and easily understand, it is right to combine below the figure and the detailed implementation mode the utility model discloses do further explanation:

the utility model provides an optical measuring piece fixing jig, as shown in figures 1-4, comprising a base 1 and two vertical stoppers 2 which are respectively arranged at two ends of the base 1 and are connected through hinges 5, the middle part of the base 1 is disconnected to form two opposite sections, one section of the inner end is fixed with an inserting rod 6, the inserting rod 6 is provided with a positioning ball 8, the inner end of the other section is provided with an inwards concave inserting hole 7, and the inner wall of the inserting hole 7 is provided with a plurality of positioning grooves 9 along the length direction; the top parts of the two limit blocks 2 are oppositely bent to form bending sections, each bending section is provided with a vertical and corresponding limit opening 21, a groove 11 is formed in the base 1 and between the two limit blocks 2, and the groove 11 is the same as and vertically corresponding to the width of the limit opening 21.

This optical measurement piece fixing jig is as shown in figure 2 before using, it is rotatory around hinge 5 axis to keeping away from 1 direction of base with both sides stopper 2 when using, it is perpendicular with base 1 to rotate at most through hinge 5 control stopper 2, as shown in figure 1, spacing mouth 21 on two stoppers 1 is relative and the bottom is parallel this moment, two spacing mouthful 21 bottom distances are the same with 11 length on the base 1 and both are in same vertical plane, the optical filter that awaits measuring passes two spacing mouths 21 earlier from the top, then the bottom is placed in recess 11, guarantee through spacing mouth 21 and recess 11 that the optical filter vertical fixation that awaits measuring is between base 1 and spacing mouth 21.

Because the thickness and the width of the optical filter to be measured are changed, the position of the optical filter to be measured is not fixed and not vertical due to the fact that the size of the groove 11 and the size of the limiting opening 21 are large when the thin optical filter is measured, and the measuring result is influenced, therefore, the first rubber block 3 and the second rubber block 4 are respectively arranged on the walls of the limiting opening 21 and the groove 11, the rubber blocks are oppositely arranged in the limiting opening 21 and the groove 11, the middle distance is small, the rubber blocks can clamp the optical filter to be measured after the optical filter to be measured is placed in, the verticality of the optical filter is guaranteed, meanwhile, the optical filter can be prevented from being in direct contact with a jig, and the coating of.

As shown in fig. 3-4, an inserting rod 6 and a length-adjusting hole 7 are arranged in the middle of a base 1, the inserting rod 6 is a rod with a non-circular cross section, the shape of the length-adjusting hole 7 is matched with the inserting rod 6, the non-circular cross section of the inserting rod 6 can prevent two parts of the base 1 from rotating, a positioning ball 8 is arranged on the inserting rod 6, the positioning ball 8 can retract downwards under stress and pop out without stress, a plurality of positioning grooves 9 matched with the positioning balls 8 are arranged in the length-adjusting hole 7, the positioning balls 8 and the positioning grooves 9 are matched to realize position control of the inserting rod 6, when in use, the extending length of the inserting rod 6 is adjusted according to the width of the optical filter to be measured, and the whole device can be placed on a testing machine after the optical filter to be measured is fixed, so that the function of; after the optical filter to be tested is used, the inserting rod 6 is completely inserted into the adjusting slot hole 7, the two side limiting blocks 2 are rotated towards the direction of the base 1 until the two side limiting blocks are attached to the top surface of the base 1, the fixing jig is convenient to store, and the optical filter to be tested does not occupy the position.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
