The experimental methods in the following embodiments are all conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified. Example
[0023] See also Figure 1 - Figure 6 A horizontal optical test contact angle measuring instrument comprises a base 1, a sample platform 2, a light source system 3, an injection unit 4 and a lens 5. The sample platform 2 is arranged on the top of the base 1, the light source system 3 is arranged on the base 1 on the right side of the sample platform 2, the injection unit 4 is arranged on the top of the light source system 3, the lens 5 is arranged on the left side of the sample platform 2, an extension component 6 is arranged in the sample platform 2, and a measuring component 7 is arranged on the left side of the sample platform 2. The extension component 6 comprises a rotating groove 61 opened in the middle of the sample platform 2, a gear 62 rotates in the rotating groove 61, two groups of torsion springs 63 are wound on the surfaces of both ends of the rotating groove 61, two groups of slide grooves 64 are opened in the sample platform 2 on both sides of the rotating groove 61, and the slide grooves 64 are connected to the rotating groove 61. The slide grooves 64 are connected, and slide rods 65 are slidable in the slide grooves 64. The two groups of slide rods 65 are staggered in design. A rack 66 is provided on the surface of the slide rod 65 on the side facing the gear 62, and the rack 66 is meshed with the gear 62. A guide groove 67 is provided on the inner wall of the slide groove 64 corresponding to the top surface of the slide rod 65, and a connecting rod 68 is provided on the surface of the slide rod 65 in the guide groove 67. A storage groove 69 is provided in the sample platform 2 above the connecting rod 68, and two groups of extension plates 610 are staggered on the top surface of the connecting rod 68. A fixed block 611 is provided on the outer wall of the right side of the sample platform 2, and a threaded rod 612 is rotated on the internal thread of the fixed block 611. Two groups of threaded grooves 613 are provided on the surface of the left side surface of the threaded rod 612 corresponding to the slide groove 64.
[0024] When in use, first pull the slide bar 65 to the side away from the base 1, so that the slide bar 65 slides in the slide groove 64, and the slide bar 65 drives the gear 62 to rotate in the rotation groove 61 through the rack 66, and the gear 62 drives the torsion spring 63 to twist, and the slide bar 65 drives another set of slide bars 65 to slide in the opposite direction in the slide groove 64 through the torsion spring 63, and the two sets of slide bars 65 synchronously drive the extension plate 610 to slide out of the storage groove 69 through the connecting rod 68, and then the threaded rod 612 is rotated to The threaded groove 613 is provided to increase the use area of the sample platform 2. When the extension plate 610 is not needed, the threaded rod 612 is rotated out of the threaded groove 613, and then the slide bar 65 is loosened. The restoring force of the torsion spring 63 is used to drive the gear 62 to rotate in the rotation groove 61, and the gear 62 acts on the two sets of racks 66 synchronously, so that the racks 66 drive the slide bar 65 to return to the slide groove 64 and slide, and the slide bar 65 drives the extension plate 610 to slide into the storage groove 69 through the connecting rod 68. It is worth noting that the slide bar 65 is designed in a C shape, and handles are staggered on the outer walls of the two sets of slide bars 65 to prevent the slide bar 65 from sliding out of the slide groove 64. At the same time, when the slide bar 65 needs to be pulled again, it is more labor-saving and stable to pull the slide bar 65 by using the handle, so as to prevent the slide bar 65 from fitting with the outer wall of the sample platform 2 under the driving force of the torsion spring 63, and causing the staff's hands to be pinched by the slide bar 65 and the sample platform 2. The slide groove 64 is designed in a T shape, and the slide bar 65 is set to be close to the slide groove 64. The shape of the groove 64 is adapted to the shape of the slide rod 65, and the slide rod 65 slides linearly in the slide groove 64, which can make the slide groove 64 and the slide rod 65 fully fit, thereby improving the stability of the slide rod 65 sliding back and forth in the slide groove 64. The end of the threaded rod 612 is designed in a pentagonal shape, and the outer wall of the end of the threaded rod 612 is ground, which can increase the friction between the staff's hand and the outside of the threaded rod 612, preventing the threaded rod 612 from being too tightly screwed with the threaded groove 613, and preventing the staff from slipping when turning the threaded rod 612.
[0025] In other embodiments, the measuring assembly 7 includes a movable bin 71 arranged on the left outer wall of the sample platform 2, a bearing 72 is provided on the inner wall of the movable bin 71, a screw rod 73 is fixedly connected to the bearing 72, a hand wheel 74 is provided on the front end surface of the screw rod 73, two sets of transmission blocks 75 are threadedly connected to the screw rod 73, a clamping plate 76 is provided on the left outer wall of the transmission block 75, a limit seat 77 is provided on the outer wall of the sample platform 2 below the movable bin 71, a measuring ruler 78 is clamped in the limit seat 77, an auxiliary plate 79 is provided on the bottom surface of the transmission block 75, and the surface of the auxiliary plate 79 is in contact with the surface of the measuring ruler 78;
[0026] When in use, first insert the measuring ruler 78 into the limit seat 77, then rotate the hand wheel 74, so that the hand wheel 74 drives the screw rod 73 to rotate on the bearing 72, and the screw rod 73 acts on the two sets of transmission blocks 75 synchronously, so that the transmission blocks 75 drive the two sets of clamping plates 76 to clamp, and the clamping plates 76 also drive the auxiliary plates 79 to slide on the measuring ruler 78 while moving, until the two sets of clamping plates 76 clamp the sample, at this time, by observing the position of the auxiliary plates 79 on the measuring ruler 78, the value on the measuring ruler 78 is read, so as to achieve the purpose of measuring the sample, and at the same time, the sample can be fixed to prevent the sample from displacement and affecting the accuracy of the test result.
[0027] It is worth noting that the two sets of clamping plates 76 are both provided with cushions on the surfaces of one side corresponding to each other, and the area of the cushions is set to be compatible with the area of the clamping plates 76, which can prevent the two sets of clamping plates 76 from clamping the sample too tightly under the drive of the transmission block 75, causing damage to the surface of the sample. The limit seat 77 is designed to be transparent, and the limit seat 77 and the measuring ruler 78 are slidably connected, which can facilitate the staff to disassemble and assemble the measuring ruler 78 so as to replace the new measuring ruler 78 for use.
