[0019] Compared with the related art, the constant temperature culture oscillator with a clamping mechanism provided by the utility model has the following beneficial effects:
[0020] The utility model provides a constant temperature culture oscillator with a clamping mechanism. When the constant temperature culture oscillator is used to culture bacteria in containers such as test tubes and beakers at a constant temperature, the water temperature in the box and the oscillation mode are set through an operation interface. After the water temperature is stabilized at the specified temperature, the test tube is placed in the oscillation frame. A limit frame on the oscillation frame is fixedly connected with two rows of long tension springs in a vertical and horizontal direction. The staggered multiple long tension springs clamp and limit the placed test tubes and beakers. Then the driving device is started, and the driving device drives the oscillation frame to oscillate. However, this operation may cause The following problem is that after the limit frame is used for a long time, one or more long tension springs on the limit frame will be deformed and fatigued, resulting in poor clamping and limiting effect on the container. Because individual long tension springs cannot be used, the entire limit frame can be directly replaced, resulting in a waste of resources. By setting an adjustment structure, when the long tension spring on the side of the limit frame away from the oscillation frame needs maintenance, the mounting tubes at both ends of the damaged long tension spring are moved away from each other at the same time, and the mounting tubes slide away from the limit frame along the mounting groove, and the long tension spring is in an extended state. Then, the two mounting tubes are operated at the same time to make the installation The mounting tube moves upward away from the limit frame, and the mounting tube drives the long tension spring to slide away from the limit frame along the opening on the mounting groove. Then a new long tension spring with a mounting tube is taken, and the mounting tubes at both ends of the long tension spring are moved away from each other at the same time, until the distance between the two mounting tubes is larger than the distance between the two corresponding mounting grooves on the limit frame. Then the mounting tubes are operated to make the long spring slide into the two mounting grooves from top to bottom first, and then the two mounting tubes are slowly released. Under the elastic force of the long tension spring, the two mounting tubes move towards each other at the same time and slide into the mounting grooves. When the two mounting tubes are close to each other, they oscillate. When replacing a row of long tension springs in a frame, it is necessary to remove the limit frame first. When it is necessary to fine-tune the tightness of the long tension spring, turn the adjusting rod, and the adjusting rod moves along the fixed plate away from the mounting tube with the help of the thread, and the adjusting rod drives the movable plate to move, and the movable plate drives the long tension spring to stretch and tighten. The long tension spring can be conveniently disassembled and assembled by operating the mounting tube, which is convenient for users to replace a certain long tension spring separately, prolonging the service life of the limit frame, and is highly economical. The tightness of a single long tension spring can be fine-tuned by operating the adjusting rod, which is highly practical.
[0021] When putting in and taking out the test tube, the user is likely to contact the constant temperature water, which may easily scald the user's hands. By setting up an auxiliary structure, the auxiliary ring is first moved in the direction away from the fixed frame, and the auxiliary ring moves along the operating rod. During this process, the spring is in a compressed state, and the auxiliary ring drives the connecting rods on both sides to move and rotate, and the connecting rod drives the clamping arms to rotate. The two clamping arms rotate and open at the same time, and then the two clamping arms are moved to the container, and the auxiliary ring is slowly released. The compressed spring gives the auxiliary ring an elastic force to move the auxiliary ring in the opposite direction, thereby rotating and closing the two clamping arms until the two clamping arms clamp the container. The soft pad is used to reduce the damage to the test tube caused by the clamping arm when it is working, and the reserved groove is used to make the clamping arm fit more fully with the arc surface of the test tube, so that the limiting effect of the clamping arm is better, so that the opening and closing of the clamping arm is controlled by operating the auxiliary ring, and the clamping arm is used to clamp the test tube and drive the test tube to move, so as to prevent the user's hands from contacting the constant temperature water in the box when putting in and taking out the test tube, causing scalding.

[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0030] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.
[0031] See also Figures 1 to 6 The utility model embodiment provides a constant temperature culture oscillator with a clamping mechanism, comprising: a box body 1, an operation interface 2 is arranged on the surface of the box body 1, a cover plate 3 is rotatably connected to the upper surface of the box body 1, an oscillation frame 4 is installed on the inner wall of the box body 1, a limit frame 5 is installed on the upper surface of the oscillation frame 4, an adjustment structure 6 is arranged on the surface of the limit frame 5, and an auxiliary structure 7 is arranged on one side of the box body 1.
[0032] In the embodiments of the present invention, please refer to Figures 2 to 4 The adjusting structure 6 includes a plurality of mounting grooves 61, and the plurality of mounting grooves 61 are arranged on the limit frame 5. The inner walls of the plurality of mounting grooves 61 are slidably connected with mounting tubes 62. The end of the mounting tube 62 away from the limit frame 5 is fixedly connected with a fixing plate 63. The inner wall of the fixing plate 63 is threadedly connected with an adjusting rod 64. The end of the adjusting rod 64 close to the mounting tube 62 is rotatably connected with a moving ring 65. The plurality of moving rings 65 form a group of two each. The side of the moving rings 65 of the same group close to each other is fixedly connected with a long tension spring 66. The long tension spring 66 can be conveniently disassembled and assembled by operating the mounting tube 62, which is convenient for the user to replace a certain long tension spring 66 separately, thereby extending the service life of the limit frame 5 and being highly economical. The tightness of a single long tension spring 66 can be fine-tuned by operating the adjusting rod 64. , it is highly practical. One end of the adjusting rod 64 away from the moving ring 65 is fixedly connected with a plurality of anti-skid protrusions 67. The plurality of anti-skid protrusions 67 are evenly distributed on the arc surface of the adjusting rod 64. The anti-skid protrusions 67 increase the friction of the operating end of the adjusting rod 64, making it convenient for the user to rotate the adjusting rod 64. The inner wall of the mounting groove 61 is rotatably connected with a pulley 68. The arc surface of the pulley 68 is slidably connected with the mounting tube 62. The pulley 68 reduces the friction between the inner wall of the mounting groove 61 and the mounting tube 62, so that the mounting tube 62 moves more smoothly along the mounting groove 61. Both sides of the inner wall of the mounting groove 61 are fixedly connected with sliding rods 69. The surface of the sliding rod 69 is slidably connected with the mounting tube 62. The sliding rod 69 further limits the mounting tube 62, so that the mounting tube 62 moves more stably along the mounting groove 61.
[0033] In the embodiments of the present invention, please refer to Figure 5 and Figure 6The auxiliary structure 7 includes an operating rod 71, which is in contact with the box body 1. The arc surface of the operating rod 71 is slidably connected with an auxiliary ring 72. The arc surface of the operating rod 71 is sleeved with a spring 73. The two ends of the spring 73 are respectively fixedly connected to the auxiliary ring 72 and the operating rod 71. Two connecting rods 74 are rotatably connected to the two sides of the auxiliary ring 72. The end of the connecting rod 74 away from the auxiliary ring 72 is rotatably connected to the clamping arm 75. The end of the operating rod 71 close to the clamping arm 75 is fixedly connected to a fixing frame 76. The inner wall of the fixing frame 76 is rotatably connected to the clamping arm 75. The clamping is controlled by operating the auxiliary ring 72. The opening and closing of the arms 75 are used to clamp the test tube and drive the test tube to move, so as to prevent the user's hands from contacting the constant temperature water in the box 1 when putting in and taking out the test tube, causing burns. The two clamp arms 75 are provided with a reserved groove 77 on the side close to each other. The reserved groove 77 is an arc groove. The clamp arms 75 are more fully fitted with the arc surface of the test tube through the reserved groove 77, so that the limiting effect of the clamp arms 75 is better. The two clamp arms 75 are fixedly connected with a soft pad 78 on the side close to each other. The soft pad 78 is a rubber pad. The soft pad 78 reduces the damage to the test tube caused by the clamp arms 75 when working.
[0034] The working principle of the constant temperature culture oscillator with a clamping mechanism provided by the utility model is as follows: by setting the adjustment structure 6, when the long tension spring 66 on the side of the limit frame 5 away from the oscillation frame 4 needs maintenance, the mounting tubes 62 at both ends of the damaged long tension spring 66 are moved away from each other at the same time, the mounting tube 62 slides away from the limit frame 5 along the mounting groove 61, and the long tension spring 66 is in an extended state, and then the two mounting tubes 62 are operated at the same time to make the mounting tube 62 move upward away from the limit frame 5, and the mounting tube 62 drives the long tension spring 66 Slide away from the limit frame 5 along the opening on the installation groove 61, then take out a new long tension spring 66 with a mounting tube 62, and similarly move the mounting tubes 62 at both ends of the long tension spring 66 in the direction away from each other until the distance between the two mounting tubes 62 is greater than the distance between the two corresponding mounting grooves 61 on the limit frame 5, and then operate the mounting tubes 62 to make the long spring 73 slide into the two mounting grooves 61 from top to bottom, and then slowly release the two mounting tubes 62. Under the elastic force of the long tension spring 66, the two mounting tubes 62 move towards each other at the same time. The adjusting rod 64 is rotated to adjust the tightness of the long tension spring 66, and the adjusting rod 64 moves along the fixed plate 63 in the direction away from the mounting tube 62 with the help of the thread. The adjusting rod 64 drives the movable plate to move, and the movable plate drives the long tension spring 66 to stretch and tighten. The friction of the operating end of the adjusting rod 64 is increased by the anti-slip protrusion 67, which is convenient for the user to rotate the adjusting rod 64, and the installation is reduced by the pulley 68. The friction between the inner wall of the mounting groove 61 and the mounting tube 62 makes the mounting tube 62 move more smoothly along the mounting groove 61. The mounting tube 62 is further limited by the sliding rod 69, so that the mounting tube 62 moves more stably along the mounting groove 61. The long tension spring 66 can be conveniently disassembled and assembled by operating the mounting tube 62, which is convenient for the user to replace a certain long tension spring 66 separately, thereby extending the service life of the limit frame 5 and being highly economical. The tightness of a single long tension spring 66 can be fine-tuned by operating the adjusting rod 64, which is highly practical.
[0035] By setting the auxiliary structure 7, the auxiliary ring 72 is first moved in a direction away from the fixing frame 76, and the auxiliary ring 72 moves along the operating rod 71. During this process, the spring 73 is in a compressed state, and the auxiliary ring 72 drives the connecting rods 74 on both sides to move and rotate, and the connecting rods 74 drive the clamping arms 75 to rotate, and the two clamping arms 75 rotate and open at the same time, and then the two clamping arms 75 are moved to the container, and the auxiliary ring 72 is slowly released. The compressed spring 73 gives the auxiliary ring 72 an elastic force, so that the auxiliary ring 72 moves in the opposite direction, and then The two clamp arms 75 are rotated and closed until the two clamp arms 75 clamp the container, wherein the soft pad 78 reduces the damage to the test tube caused by the clamp arms 75 when working, and the reserved groove 77 makes the clamp arms 75 fit more fully with the arc surface of the test tube, so that the limiting effect of the clamp arms 75 is better, and the opening and closing of the clamp arms 75 are controlled by operating the auxiliary ring 72, and the clamp arms 75 are used to clamp the test tube and drive the test tube to move, thereby preventing the user's hands from contacting the constant temperature water in the box 1 when putting in and taking out the test tube, causing burns.
