Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] Please refer to Figure 1-4 , the present invention provides a technical solution:

[0022] A chromatin immunoprecipitation sample storage device includes a storage box 1. Positioning plates 2 are respectively fixedly installed on the inner walls on both sides of the storage box 1. Sliding grooves 3 are respectively opened on the opposite side walls of the two groups of positioning plates 2. A sample storage rack 4 is arranged between the two groups of positioning plates 2. A plurality of receiving grooves 5 are opened at the top of the sample storage rack 4. Sample tubes 6 are respectively arranged inside the plurality of receiving grooves 5. Clamping assemblies 7 that can be adaptively adjusted and clamp and position the sample tubes 6 are respectively arranged on both sides of the inner walls of the plurality of receiving grooves 5. By opening a plurality of receiving grooves 5 on the sample storage rack 4 and respectively arranging clamping assemblies 7 inside the plurality of receiving grooves 5, the stored sample tubes 6 can be clamped and positioned, avoiding the situation that the sample tubes 6 shake or even fall during storage, which is beneficial to improving the storage stability of the sample tubes 6. And the clamping assembly 7 can be adaptively adjusted according to the diameter of the sample tube 6, and sample tubes 6 with different diameters can be stored, which is beneficial to further improving the use flexibility of the storage device;

[0023] The clamping assembly 7 includes a relief groove 701 opened on the inner wall of the receiving groove 5. A return spring 702 is fixedly connected to one side inner wall of the relief groove 701. One end of the return spring 702 is fixedly connected to a sliding column 703. One end of the sliding column 703 is fixedly connected to a clamping plate 704;

[0024] Specifically, when the sample tube 6 needs to be stored, the sample tube 6 can be directly inserted into the two sets of clamping plates 704 from top to bottom. The outer wall of the sample tube 6 will squeeze the two sets of clamping plates 704, thereby squeezing the sliding column 703, causing the sliding column 703 to slide into the inside of the让位槽701. At this time, the return spring 702 is in a compressed state. At the same time, the return spring 702 can be used to drive the clamping plate 704 to clamp and position the sample tube 6, avoiding the situation of shaking or even tipping of the sample tube 6 during storage, which is beneficial to improving the stability of the storage of the sample tube 6, and can be adjusted adaptively according to the diameter of the sample tube 6, and sample tubes 6 with different diameters can be stored;

[0025] The sliding column 703 is slidably inserted into the inside of the让位槽701, and a V-shaped groove 8 is provided on one side wall of the clamping plate 704. By setting the V-shaped groove 8, it is beneficial to improve the clamping stability of the cylindrical sample tube 6;

[0026] Sliding blocks 9 adapted to the sliding grooves 3 are respectively fixedly connected to the two side walls of the sample storage rack 4. The two sliding blocks 9 are respectively slidably connected to the inside of the two sliding grooves 3. Guide rods 10 are respectively fixedly connected to one side walls of the two sliding blocks 9. One ends of the two guide rods 10 respectively penetrate through the two positioning plates 2 and are fixedly connected with anti-disengagement parts, and the two guide rods 10 are respectively slidably connected to the two positioning plates 2;

[0027] By adopting the above case, through the cooperation of the sliding grooves 3, the sliding blocks 9, the guide rods 10 and the anti-disengagement parts, the sample storage rack 4 can be easily pulled out from the inside of the storage box 1, so that it is convenient for the experimenter to take or store the chromatin immunoprecipitation sample;

[0028] A U-shaped supporting plate 11 is fixedly connected to the bottom of the sample storage rack 4. A plurality of supporting pads 12 are fixedly connected to the inner bottom of the U-shaped supporting plate 11. The plurality of supporting pads 12 are respectively located directly below the plurality of receiving grooves 5. By setting the cooperation of the U-shaped supporting plate 11 and the supporting pads 12, it plays a role in protecting the bottom of the sample tube 6, avoiding the bottom of the sample tube 6 from being knocked and damaged, so as to avoid the chromatin immunoprecipitation sample from flowing out and causing waste and pollution;

[0029] A refrigeration device body 13 is fixedly installed at the bottom of the storage box 1, and the refrigeration end of the refrigeration device body 13 is located inside the storage box 1. A temperature sensor 14 is fixedly connected to the inner top of the storage box 1. Lights 15 are fixedly connected to the inner walls on both sides of the storage box 1 respectively. A control panel 16 is fixedly installed on one side wall of the storage box 1. The refrigeration device body 13, the temperature sensor 14 and the light 15 are all electrically connected to the control panel 16 through wires. The circuit connection is an existing mature technology. The specific connection method and working principle are no longer repeated here. The refrigeration device body 13, the temperature sensor 14 and the light 15 can be started and stopped through the control panel 16. By setting the temperature sensor 14, the temperature inside the storage box 1 is monitored in real time, so that the temperature can be controlled within a suitable range. By setting the light 15, it is convenient for experimenters to observe the storage status of the chromatin immunoprecipitation sample. A sealing door is hinged on one side of the storage box 1 to provide good sealing for the storage box 1, ensuring that the chromatin immunoprecipitation sample is not affected by the external ambient temperature during storage.
