[0023] To further illustrate the technical means and effects adopted by the utility model in order to achieve the intended purpose of the utility model, the following detailed description of the specific implementation methods, structure, features and effects of the utility model, in conjunction with the accompanying drawings and preferred embodiments, is provided below.
[0024] Please see Figures 1-7 As shown, the purpose of this embodiment is to provide a fixture for fixing block samples in a benchtop colorimeter, including a fixture body 1, a sample placement cavity 2 inside the fixture body 1, a square light-transmitting hole 3 at the center of the sample placement cavity 2, magnetic posts 4 fixed on both sides of the fixture body 1, two first clamping components 5 slidably installed inside the fixture body 1, each of the first clamping components 5 being fixedly installed with a third clamping component 8, fixing components 6 on both sides of the fixture body 1, and second clamping components 7 on both sides of the sample placement cavity 2, with both ends of the second clamping components 7 being fixedly connected to the fixing components 6;
[0025] The magnetic column 4 can be adsorbed onto the metal parts of the benchtop colorimeter to fix the position of the fixture body 1. When adjusting the spacing of the clamping plates 51, the adsorption of the magnetic column 4 can ensure that the fixture body 1 will not move arbitrarily due to external forces during operation, providing a stable basis for the precise adjustment of the clamping plates 51, thereby better adapting to the fixing requirements of samples of different sizes.
[0026] Slide grooves 21 are provided on both sides of the lofting cavity 2. The slide grooves 21 are used to facilitate the sliding of the first clamping component 5 in the lofting cavity 2.
[0027] It should be noted that the length of the slide 21 is the same as the width of the lofting cavity 2.
[0028] The first clamping assembly 5 includes at least a clamping plate 51. A bolt groove 52 is provided at the center of one side of the clamping plate 51. Both ends of the clamping plate 51 are fixedly connected to protrusions 53. One side of each protrusion 53 is fixedly connected to a spring 54. One end of the spring 54 is fixedly connected to the slide groove 21.
[0029] Each bolt groove 52 is provided with a sliding column groove 521, and each clamping plate 51 is slidably installed with a sliding column 523. One end of each sliding column 523 is fixedly connected to a limiting member 522, and the limiting member 522 is slidably installed in the sliding column groove 521.
[0030] Each of the third clamping components 8 includes at least a plurality of baffle springs 81, one end of each baffle spring 81 is fixedly connected to a clamping plate 51, and the other end of each baffle spring 81 is fixedly connected to a silicone baffle 82.
[0031] After the bolt 62 enters the bolt groove 52, it pushes the limiting member 522, causing the sliding column 523 to move forward, which in turn pushes the silicone baffle 82, causing all the baffle springs 81 to stretch.
[0032] At the same time, when the limiting member 522 is limited by the sliding groove 521, it drives the pushing plate 51 to move inward, thereby causing the protrusion 53 to slide in the sliding groove 21, thus stretching the spring 54.
[0033] It should be noted that the lofting cavity 2 is tightly fitted with the clamping plate 51, the clamping plate 51 slides horizontally parallel to the lofting cavity 2, and the width of the protrusion 53 is the same as the width of the slide groove 21.
[0034] When the silicone baffle 82 is not under any force, the side of the initial position is at the same level as the side of the clamp 51, thus solving the problem of samples of different sizes.
[0035] The clamp body 1 has screw holes 61 at the center of both sides. The fixing component 6 includes at least bolts 62. The screw holes 61 and bolts 62 are threadedly connected. The bolts 62 rotate in the screw holes 61, thereby pushing the clamping plate 51 to slide left and right, so that the telescopic rod 75 fixes the sample left and right.
[0036] It should be noted that the bottom of bolt 62 is not threaded, and the diameter of the unthreaded part is slightly smaller than the diameter of the threaded part. When the sample does not need to be fixed initially, bolt 62 is not threaded to the screw hole 61. When the sample is fixed, bolt 62 moves outward through screw hole 61. When there is no threaded connection between bolt 62 and screw hole 61, the compression on clamp 51 disappears, spring 54 rebounds, pulls clamp 51 back to its original position, and bolt 62 is fixed to the outside of the sample cavity, with bolt 62 perpendicular to clamp 51.
[0037] The second clamping assembly 7 includes at least two support rods 73, each of which is fixedly connected to a rotating ball 74 at both ends. Each rotating ball 74 is rotatably connected to a rotating shaft 72. The second clamping assembly 7 also includes two fixed blocks 71, two rotating blocks 76, and one telescopic rod 75. The fixed blocks 71 and the rotating blocks 76 are both provided with grooves. The rotating shaft 72 is fixedly installed in the grooves. The fixed blocks 71 are fixedly connected to the protrusions 53. The telescopic rod 75 is fixedly installed between the rotating blocks 76.
[0038] When bolt 62 pushes clamp 51 to move, under the action of clamp 51, fixing block 71 moves towards the middle of clamp body 1, so that under the action of fixing block 71, one end of support rod 73 is centered on fixing block 71, so that the support rod 73 gradually changes from horizontal to vertical, thereby causing rotating ball 74 to rotate on rotating shaft 72, and support rod 73 moves towards sample placement cavity 2. At the same time, rotating block 76 rotates under the action of rotating ball 74 through rotating shaft 72, thereby driving telescopic rod 75 to stretch, so that telescopic rod 75 fixes the front and rear sides of sample.
[0039] It should be further explained that when the bolt 62 stops pushing, the angle between the telescopic rod 75 and the support rod 73 is 90°. The rotation angle of the rotating ball 74 within the fixed block 71 is less than 90°. When the bolt 62 does not push the clamping plate 51, the initial position of the support rod 73 is slightly offset towards the sample placement cavity 2, which facilitates the inward movement of the fixed block 71. The support rod 73 is then compressed and moves in the offset direction, facilitating the clamping of the sample by the second clamping assembly 7. The telescopic rod 75 is symmetrical so that the part of the sample being clamped is on the same horizontal plane and will not tilt.
[0040] In practical use, the fixture is placed on a benchtop colorimeter, and the magnetic column 4 is attracted to the metal part of the benchtop colorimeter to fix the position of the fixture body 1. When adjusting the spacing of the clamping plates 51, the attraction of the magnetic column 4 can ensure that the fixture body 1 will not move arbitrarily due to external force during operation, providing a stable basis for the precise adjustment of the clamping plates 51, thereby better adapting to the fixing needs of samples of different sizes.
[0041] By rotating the bolt 62 in the bolt hole 61, the bottom of the bolt 62 contacts the bolt groove 52. After the bolt 62 enters the bolt groove 52, it pushes the limiting member 522, causing the sliding column 523 to move forward. The sliding column 523 pushes the silicone baffle 82, causing all the baffle springs 81 to be stretched. At the same time, when the limiting member 522 is limited by the sliding column groove 521, it drives the pushing clamp 51 to move inward, thereby causing the protrusion 53 to slide in the sliding groove 21, thus stretching the spring 54.
[0042] Under the action of clamping plate 51, fixing block 71 moves towards the middle of clamp body 1, so that under the action of fixing block 71, one end of support rod 73 is centered on fixing block 71, so that the support rod 73 gradually changes from horizontal to vertical, thereby causing rotating ball 74 to rotate on rotating shaft 72. Support rod 73 moves towards sample placement cavity 2. At the same time, rotating block 76 rotates under the action of rotating ball 74 through rotating shaft 72, thereby driving telescopic rod 75 to stretch, so that telescopic rod 75 fixes the sample front and back.
[0043] After the experiment, the bolt 62 is rotated in the opposite direction. Under the action of the spring 54, the clamp 51 moves with the bolt 62, so that the bottom of the bolt 62 does not contact the bolt groove 52. Then the tension of the baffle spring 81 disappears, and it pulls the silicone baffle 82 through its own elastic force to reset it.
[0044] At the same time, when the clamping plate 51 moves to both sides, the fixing block 71 and the support rod 73 move to both sides, and the telescopic rod 75 retracts.
