Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] See also Figure 1-5 The utility model provides a technical solution: a foldable test tube rack, comprising a support frame 1, the inner wall of the support frame 1 is rotatably connected to a round rod 2, the arc surface of the round rod 2 is fixedly connected to a containing frame 3, one end of the round rod 2 is fixedly connected to a special-shaped column 4, a fixing device 5 is provided on the side of the support frame 1, and a protective device 6 is provided on the lower surface of the containing frame 3.
[0029] The specific arrangement and function of the fixing device 5 and the protective device 6 will be described in detail below.
[0030] like Figure 1-3As shown, the fixing device 5 includes a U-shaped plate 51, which is fixedly connected to the support frame 1, and a moving rod 52 is slidably connected to the surface of the U-shaped plate 51, and a circular ring 53 is fixedly connected to the surface of the moving rod 52, and the size of the circular ring 53 is adapted to the size of the special-shaped column 4. A fixing plate 54 is fixedly connected to the side of the support frame 1, and a sliding rod 55 is slidably connected to the surface of the fixing plate 54, and a surface of the sliding rod 55 is fixedly connected to a limiting plate 56, and the limiting plate 56 passes through the U-shaped plate 51. A spring 57 is installed on the arc surface of the sliding rod 55, and the two ends of the spring 57 are fixedly connected to the fixing plate 54 and the limiting plate 56 respectively. The sliding rod 55 on the fixing plate 54 will be moved upward by the elastic force of the spring 57. At this time, the spring 5 7 will change from an extruded state to an extended state, at which time the limit plate 56 will pass through the U-shaped plate 51, and the limit plate 56 will move upward under the drive of the spring 57, and the limit plate 56 on the slide bar 55 can limit the position of the circular ring 53 to prevent the situation that the use of the rotating holding rack 3 is affected when the holding rack 3 is rotated, and the inner wall of the U-shaped plate 51 is fixedly connected with a fixed column 58, and the arc surface of the fixed column 58 is rotatably connected with a rotating plate 59, and the rotating plate 59 is rotated to the surface of the limit plate 56, and the rotating plate 59 can limit the position of the limit plate 56 to prevent the elastic force of the spring 57 from driving the limit plate 56 to move upward, and prevent the circular ring 53 from failing to fix the round rod 2 normally.
[0031] like Figure 1-5 As shown, the protective device 6 includes a card frame 61, which is engaged with the placing rack 3, and a placement box 62 is fixedly connected to the lower surface of the card frame 61. A sponge pad 63 is slidably connected to the inner wall of the placement box 62. An L-shaped plate 64 is fixedly connected to the surface of the placement box 62. A screw 65 is threadedly connected to the surface of the L-shaped plate 64. A bottom plate 66 is fixedly connected to the surface of the sponge pad 63. The screw 65 is against the surface of the bottom plate 66. When the screw 65 is rotated, the screw 65 will rotate on the L-shaped plate 64. When the screw 65 is rotated to contact the bottom plate 66, the screw 65 can fix the position of the sponge pad 63 on the same horizontal line, thereby preventing inequality or instability from occurring when placing the test tubes. A slider 67 is slidably connected to the inner wall of the placement box 62. The slider 67 is fixedly connected to the sponge pad 63. The slider 67 can limit the moving distance of the sponge pad 63 to prevent the sponge pad 63 from being driven to rotate by the screw 65, causing the sponge pad 63 to be squeezed and deformed.
[0032] Working principle: when the holding rack 3 is not in use, the holding rack 3 can be folded and retracted. When the holding rack 3 is used to place the test tube, the moving rod 52 is pulled, and the movement will drive the circular ring 53 to move in the direction away from the special-shaped column 4. Then, when the moving rod 52 drives the circular ring 53 to break contact with the special-shaped column 4, the rotating plate 59 is rotated, and the rotating plate 59 will rotate on the fixed column 58. When the rotating plate 59 rotates toward one end of the U-shaped plate 51, the sliding rod 55 on the fixed plate 54 will be moved upward by the elastic force of the spring 57. At this time, the spring 57 begins to stretch, and the limiting plate 56 will pass through the U-shaped plate 51. The limiting plate 56 will move upward driven by the spring 57. The limiting plate 56 on the sliding rod 55 can limit the position of the circular ring 53 to prevent the rotating holding rack 3 from being affected when the holding rack 3 is rotated. When the situation of using the bracket 53 occurs, the holding rack 3 can rotate on the round rod 2. Then, when the holding rack 3 rotates to a horizontal straight line, the sliding rod 55 is pulled, and the sliding rod 55 drives the limiting plate 56 to move downward. At this time, the spring 57 will be compressed. When the limiting plate 56 is out of contact with the circular ring 53, the rotating plate 59 is then rotated to the surface of the limiting plate 56. At this time, the rotating plate 59 can limit the position of the limiting plate 56 to prevent the elastic force of the spring 57 from driving the limiting plate 56 to move upward and the circular ring 53 from failing to fix the round rod 2 normally. By setting the fixing device 5, the position of the holding rack 3 can be folded and retracted, so that when the holding rack 3 is not in use, the holding rack 3 will not occupy a large space or area, thereby increasing the convenience of storing the holding rack 3.
[0033] When the holding rack 3 is in use, the placement box 62 is moved, and the card frame 61 on the placement box 62 will move with the placement box 62. At this time, the card frame 61 on the placement box 62 will be engaged with the holding rack 3. The placement box 62 can protect the lower surface of the test tube to prevent the test tube from breaking or the liquid in the test tube from leaking when the test tube is inserted into the holding rack 3. When the test tube is placed in the placement box 62, the slider 67 in the placement box 62 will drive the sponge pad 63 to move downward. The sponge pad 63 in the placement box 62 can prevent the liquid in the test tube from leaking and overflowing, and further prevent the outflowing liquid from flowing downward. The screw 65 is then rotated, and the screw 65 will rotate on the L-shaped plate 64. When the screw 65 rotates to contact the bottom plate 66, the screw 65 can fix the position of the sponge pad 63 on the same horizontal line, thereby preventing imbalance or instability when placing the test tube. The slider 67 can limit the moving distance of the sponge pad 63 to prevent the sponge pad 63 from being squeezed and deformed by the screw 65. By setting the protective device 6, the test tube can be buffered when the test tube is placed to prevent the test tube from breaking and causing liquid to flow out, thereby improving the practicality of the test tube rack.
