Detailed Description

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

The first embodiment is as follows: a visible spectrophotometer is shown in figures 1 to 6,

firstly, people take a case structure 1, the case structure 1 is provided with a sample groove 2, the opening of the sample groove 2 is gradually reduced from top to bottom, a concave part for communicating the sample groove 2 with the outside is arranged on the case structure 1, the width of the concave part is the same as that of the sample groove 2, the depth of the concave part is smaller than that of the sample groove 2, then people install a U-shaped frame 9 on the bottom surface of the sample groove 2, the overlooking section of the U-shaped frame 9 is U-shaped, the opening faces the concave part, then people paste a rubber pad 7 on the bottom surface of the concave part, a rubber pad 10 is adhered on the top surface of the U-shaped frame 9, then people process two chutes 3 on the left side wall and the right side wall of the sample groove 2 through milling cutters, the bottom surface of the chute 3 and the top surface of the U-shaped frame 9 are at the same horizontal height, then people paste an elastic layer made of rubber material on the bottom surface of, then, a groove 11 is machined on one side of the sliding groove 3 facing the concave position through a milling cutter, a rotating shaft 16 is taken, a bearing 17 is in interference fit with the rotating shaft 16, a rotating block 13 is adhered to the side wall of the bearing 17, the rotating block 13 is cylindrical, a through groove 14 is formed in the outer circumferential wall of the rotating block 13 in a concave mode towards the circle center, the through groove 14 is cubic, then, the bearing 17 is installed in the groove 11 and is adhered to the inner wall of the groove 11, the rotating block 13 is also located in the groove 11, the opening of the through groove 14 is aligned with the opening of the passage, a gap 12 exists between the rotating block 13 and the inner wall of the groove 11, then, a cubic sliding block 15 is connected in the passage in a sliding mode, a sample cover 5 used for shielding the sample groove 2 and the concave position is adhered between the sliding blocks 15 on two sides, and finally, a connecting shaft 18 is adhered to one side, close to the concave position, of, a shaft sleeve 19 is rotatably connected to the connecting shaft 18, a connecting rod 20 is integrally formed on the shaft sleeve 19, a clamping hook 21 is integrally formed at one end, away from the shaft sleeve 19, of the connecting rod 20, a clamping block 6 is bonded to the case structure 1, and meanwhile the length of the connecting rod 20 is smaller than the distance between the shaft sleeve 19 and the clamping block 6.

When people need to open the sample groove 2, people can rotate the connecting rod 20 in a manual mode, the connecting rod 20 drives the clamping hook 21 to deviate, the connecting rod 20 rotates around the connecting shaft 18 through the shaft sleeve 19, so that the clamping block 6 is separated from the clamping hook 21 and the connecting rod 20, the sample cover 5 is separated from the case structure 1, then people can pull the sample cover 5 in a manual mode, the sample cover 5 can be separated from the bottom surface inclined plane 8 of the top plate 4, because the distance between the top plate 4 and the sample cover 5 is reduced from one side of the concave part to one side of the sample groove 2, when the sample cover 5 moves to the side with larger distance, the acting force of the top plate 4 on the sample cover 5 is continuously reduced until the acting force disappears, the elastic layer, the first rubber pad 10 and the second rubber pad 7 release elastic potential energy and restore to the original state, then the sample cover 5 drives the sliding block 15 to move in the channel until the through groove 14 of the rotating block 13, then, people pull the sample cover 5 in a manual mode, the sample cover 5 drives the rotating block 13 to rotate through the sliding block 15, at least one stress point exists between the sliding block 15 and the through groove 14 in the rotating block 13, so that the sliding block 15 can drive the rotating block 13 to rotate, the rotating block 13 is fixedly connected to the rotating shaft 16, the rotating shaft 16 is sleeved in the bearing 17, the bearing 17 is fixedly connected in the groove 11, so that the rotating block 13 smoothly rotates in the groove 11, the sample groove 2 is opened, after people put a detected object into the sample groove 2, people turn over the sample cover 5 until the sample cover 5 is contacted with the second rubber pad 7 on the bottom surface of the concave part, at the moment, the sample cover 5 is also contacted with the first rubber pad 10 on the U-shaped frame 9, then people push the sample cover 5 in a manual mode, so that the sample cover 5 completely enters the sample groove 2, and in the process, the sample cover 5 is limited by the inclined surface 8 on the bottom surface of the top plate 4, because the distance between the top plate 4 and the sample cover 5 is reduced from one side of the concave part to one side of the sample groove 2, when the sample cover 5 moves to the side with smaller distance, the sample cover 5 is enabled to receive downward acting force from the top plate 4, the sample cover 5 acts on the sliding block 15 under the action of the acting force, the sliding block 15 presses the elastic layer downwards, so that the elastic layer generates elastic deformation, meanwhile, the bottom surface of the sample cover 5 is tightly attached to the inner wall of the sample groove 2, meanwhile, the sample cover 5 also presses the rubber pad 10 on the top surface of the U-shaped frame 9, so that the gaps between the sample groove 2 and the sample cover 5 and between the sample cover 5 and the U-shaped frame 9 are smaller, impurities in the air are not easy to enter the sample groove 2 to influence the experimental result, then, people drive the connecting rod 20 to rotate in a manual mode, the connecting rod 20 rotates on the connecting shaft 18 by taking the connecting shaft sleeve 19 as the circle center, then connecting rod 20 drives trip 21 and goes into between trip 21 and the connecting rod 20 with fixture block 6 card, and because the length of connecting rod 20 is less than the interval between axle sleeve 19 and the fixture block 6, thereby when making fixture block 6 card go into between connecting rod 20 and the trip 21, need take place the elastic deformation of certain degree between trip 21 and the connecting rod 20, and elastic recovery performance between trip 21 and the connecting rod 20 tries the reconversion, thereby make trip 21 can produce certain extrusion effort to trip 6, thereby make the closed structure can play better connection effect to sample lid 5 and quick-witted case structure 1 when closed.

Example two: a visible spectrophotometer, which differs from the first embodiment in that:

when people need close the closed structure, people only need rotate the connecting plate through manual mode, the connecting plate then can drive magnet one and use the articulated department of connecting plate and sample lid 5 to take place to deflect as the centre of a circle, then magnet one carries out the actuation with magnet two on the quick-witted case structure 1, thereby make sample lid 5 and quick-witted case structure 1 obtain better being connected, and when people need open the closed structure, people only need make magnet one and magnet two take place to separate through manual mode, then at the rotation connecting plate, make the connecting plate use the pin joint with sample lid 5 to take place to deflect as the centre of a circle can.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
