Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

The jig for unloading the optical filter shown in fig. 1-3 comprises a base 10 and a supporting frame 6; the supporting frame 6 is formed by combining two supporting rods, three groups of supporting frames 6 are uniformly distributed on the top of the base 10 by taking the supporting frames as the circle center, fixed blocks 5 are obliquely welded at the middle positions of the inner sides of the supporting frames 6, a rotating shaft 3 is rotatably connected at the top of the inner side of the supporting frame 6, a limiting rod 4 is obliquely sleeved on the rotating shaft 3, protective housings 16 are fixed at the outer sides of the supporting frames 6 at the two ends of the rotating shaft 3, connecting shafts 17 are transversely installed in the protective housings 16, one ends of the connecting shafts 17 are connected with the rotating shaft 3, torsion springs 18 are sleeved on the connecting shafts 17, sliding grooves 7 are formed in the inner walls of the two sides of the supporting frame 6 right below the fixed blocks 5, connecting blocks 1 are slidably connected at the positions of the sliding grooves 7, sliding blocks 12 which slide with the sliding grooves 7 mutually are, and the top of the other end of loop bar seat 8 is articulated each other with the bottom of gag lever post 4, the other end of loop bar seat 8 is fixed with supporting shoe 9, recess 13 is seted up to the positive bottom surface of gag lever post 4, and the inside welding of recess 13 has second reset spring 14, the other end of second reset spring 14 is connected with stopper 15, and stopper 15 is the right trapezoid structure, the top of supporting shoe 9 has all bonded the rubber pad, the top of base 10 is circular structure, and the angle between the three support frame 6 that the base 10 top set up is 120, the welding has first reset spring 2 on the inclined plane of fixed block 5, and the other end of first reset spring 2 and the back of gag lever post 4 mutual weld.

The specific application process comprises the following steps:

firstly, a special optical filter is transversely placed among three limiting rods 4 and supported by the limiting rods 4, then the special optical filter moves along the bottoms of the three limiting rods 4 and the limiting rods 4, so that a supporting block 9 arranged at the other end of a loop bar seat 8 supports the edge position of the special optical filter, meanwhile, the edge of the special optical filter is limited by the matching of a second reset spring 14 inside a groove 13 and the limiting block 15, the optical filter is prevented from moving up and down, when the optical filter moves downwards along the limiting rods 4 and passes through the position of the limiting block 15, because one surface of the limiting block 15 is an inclined surface, the limiting block 15 moves towards the inside of the groove 13 when the special optical filter continues to move downwards, and then when the special optical filter falls on the supporting block 9, the limiting block 15 is reset under the action of the second reset spring 14, thereby limiting the edge of the optical filter, preventing the optical filter from moving up and down and influencing the effect of the lower piece, on one hand, the first reset spring 2 resets the limiting rod 4 in the process of downward movement of the optical filter, so that the front surface of the limiting rod 4 is always kept attached to the edge position of the optical filter, the optical filter is convenient to clamp and use, meanwhile, as the limiting rod 4 and the support frame 6 are hinged with each other through the rotating shaft 3, the distance between the bottom ends of the three limiting rods 4 is changed along with the angle change between the limiting rod 4 and the support frame 6, and the limiting rod 4 is extruded by downward movement of the optical filter, so that the limiting rod 4 is extruded towards the inner side of the support frame 6, the special optical filters with different sizes are convenient to clamp and use, on the other hand, through the matching between the connecting shaft 17 inside the protective housings 16 at the two ends of the rotating, further increasing the reset force of the limiting rod 4, thereby further improving the tightness between the limiting rod 4 and the optical filter and preventing the optical filter from moving, meanwhile, in the process of changing the angle of the limiting rod 4, because the angle of the bottom end of the limiting rod 4 changes and is connected with the loop bar seat 8 through the articulated shaft, the loop bar seat 8 moves towards the bottom of the sleeve seat 11 so as to change the distance between the three supporting blocks 9 according to the angle change of the limiting rod 4, meanwhile, in the process of changing the angle of the limiting rod 4, the distance between the bottom end of the limiting rod 4 and the top of the loop bar seat 8 also changes, thereby, in the process of pressing the loop bar seat 8 by the limiting rod 4, the connecting block 1 at one end of the sleeve seat 11 slides along the inside of the chute 7, thereby being convenient to change according to the distance between the limiting rod 4 and the loop bar seat 8 and being convenient to keep the supporting blocks 9 in a horizontal state forever, the convenience supports spacingly to the not light filter of equidimension, and convenient to use when spacing fixed back to the light filter, the staff presses the top surface of light filter gently, makes the light filter drop convenient to use.

According to the above, the utility model discloses the angle change between gag lever post 4 and the support frame 6 has changed the distance of bottom between three gag lever posts 4, and the convenience carries out the centre gripping to the special light filter of equidimension not, and convenient to use, supporting shoe 9 keeps the horizontality forever along with the change of gag lever post 4 bottom angle simultaneously, and the convenience supports spacingly, convenient to use to the light filter of equidimension not.

It will be appreciated by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as limitations of the present invention, and that changes and modifications to the above described embodiments will fall within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
