Description

Technical Field

[0001] This application relates to the field of constant temperature chamber technology, specifically a constant temperature placement device for protein precipitation plates. Background Technology

[0002] In the BCA protein quantification experiment, the protein needs to be placed in a precipitation plate first, and then the precipitation plate needs to be placed in an incubator for reaction. The incubator can reduce the reaction time between the protein and the solvent.

[0003] During the use of the incubator, it is necessary to reduce the number of times the door is opened. Therefore, a sufficient amount of precipitate plates are placed inside the incubator at one time during the experiment. However, sufficient spacing needs to be maintained between the precipitate plates to ensure the normal reaction of the protein in the precipitate plates. However, the precipitate plates are usually placed manually by the experimenter, and the distance between the precipitate plates depends on the experimenter's personal experience. This can lead to the distance between adjacent precipitate plates being too small, which ultimately affects the full reaction of the protein in the incubator.

[0004] Therefore, this application provides a constant temperature placement device for protein precipitation plates to solve the above problems. Utility Model Content

[0005] This application provides a constant temperature placement device for protein precipitation plates, which aims to solve the problem mentioned in the background art that existing precipitation plates need to maintain sufficient spacing to ensure the normal reaction of proteins in the precipitation plates. However, when placing precipitation plates, they are usually placed manually by the experimenter, and the distance between precipitation plates depends on the experimenter's personal experience. This can lead to problems such as the distance between adjacent precipitation plates being too small, which ultimately affects the full reaction of proteins in the constant temperature chamber.

[0006] To achieve the above objectives, this application provides the following technical solution: a constant temperature placement device for protein precipitation plates, comprising a constant temperature chamber, a placement grid frame disposed inside the constant temperature chamber for placing precipitation plates, and a support frame fixedly disposed on the inner wall of the constant temperature chamber for supporting the placement grid frame;

[0007] To facilitate maintaining the distance between adjacent sedimentation plates: a separator component is provided at the top of the placement frame to separate adjacent sedimentation plates; a clamping component is provided at the bottom of the separator component for connection with the placement frame; and a connector is fixedly provided at the top of the clamping component for connection with the separator component. By pulling the movable claw, the movable claw and the fixed claw are clamped and connected to the placement frame, thereby completing the connection between the mounting block and the placement frame. Then, one end of the separator bar contacts one side of the sedimentation plate, and the limiting block is pressed to insert the insertion block into the corresponding adjustment hole, thus fixing the separator bar to the mounting block. At this time, the adjacent sedimentation plate is placed at the other end of the separator bar. In this way, the fixed-size separator bar can maintain the required distance between adjacent sedimentation plates, and the operation is more convenient without relying on personal experience.

[0008] Preferably, to facilitate the separation of adjacent sedimentation plates: the separation assembly includes a separator strip disposed at the top of the placement frame for separating adjacent sedimentation plates, and contact rods symmetrically disposed at both ends of the separator strip for contacting the sedimentation plates. By placing the separator strip between adjacent sedimentation plates, the distance between adjacent sedimentation plates is maintained.

[0009] Preferably, to reduce the impact on the sedimentation plate: the end of the separator strip is fixedly connected to the outer wall of the contact rod, and the horizontal cross-section of the contact rod is circular. The contact between the contact rod and the sedimentation plate reduces the impact of the separator strip on the sedimentation plate.

[0010] Preferably, to facilitate adjustment of the position of the divider strip: an adjustment hole for adjusting the position of the divider strip is provided at its top end, and the connector is inserted into the adjustment hole. The position of the divider strip is adjusted by inserting the connector into the adjustment hole at different positions.

[0011] Preferably, to facilitate the installation of the clamping assembly and the placement frame: the clamping assembly includes a fixed claw and a movable claw inserted inside the placement frame for clamping the placement frame; a limiting plate fixedly disposed at one end of the movable claw for restricting the movement of the movable claw; a return spring disposed on the side of the limiting plate away from the movable claw for pulling the limiting plate; and a mounting block sleeved outside the return spring for slidingly inserting the movable claw. The fixed claw and the movable claw respectively engage the frame of the placement frame, thereby restricting the movement of the clamping assembly.

[0012] Preferably, one end of the mounting block is fixedly connected to one side of the fixed claw, and the other end of the mounting block is provided with a first insertion hole for sliding through the movable claw. The interior of the mounting block is provided with a first cavity for installing the limiting plate and the pull-back spring, and the first insertion hole and the first cavity are interconnected.

[0013] Preferably, to facilitate the installation of the separating component and the clamping component: the connecting member includes an insert fixedly connected to the top of the mounting block for insertion into the separating component, limiting blocks symmetrically arranged on both sides of the insert for restricting the vertical movement of the separating component, a baffle fixedly arranged at one end of the limiting block for restricting the movement of the limiting block, and a push spring arranged on the side of the baffle away from the limiting block for pushing the baffle. By pressing the limiting block, the separating strip and the mounting block can be quickly installed by inserting the insert into the adjusting hole or removing the insert from the adjusting hole.

[0014] Preferably, the insert block has a second cavity inside for installing the baffle and the push spring, and the inner wall of the second cavity has a second insertion hole for inserting the limiting block.

[0015] This application utilizes the design of a separator component, a clamping component, and a connector. By pulling the movable claw, the movable claw and the fixed claw are clamped and connected to the placement frame. Then, one end of the separator bar contacts one side of the sedimentation plate, and the limiting block is pressed to insert the insertion block into the corresponding adjustment hole, thus fixing the separator bar to the mounting block. At this point, the adjacent sedimentation plate is placed on the other end of the separator bar. In this way, the distance between adjacent sedimentation plates can be maintained to meet the requirements by using a separator bar of fixed size, and the operation is more convenient without relying on personal experience.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] This embodiment provides a constant-temperature placement device for protein precipitation plates, such as... Figure 1-7 As shown, the constant temperature placement device includes a constant temperature chamber 1, a placement grid 2 set inside the constant temperature chamber 1 for placing sedimentation plates, and a support frame 3 fixedly set on the inner wall of the constant temperature chamber 1 for supporting the placement grid 2.

[0027] To facilitate maintaining the distance between adjacent sedimentation plates: a separator component 4 is installed at the top of the placement frame 2 to separate adjacent sedimentation plates; a clamping component 5 is installed at the bottom of the separator component 4 to connect with the placement frame 2; and a connector 6 is fixedly installed at the top of the clamping component 5 to connect with the separator component 4. By pulling the movable claw 52, ​​the movable claw 52 and the fixed claw 51 are clamped and connected to the placement frame 2, thus completing the connection between the mounting block 55 and the placement frame 2. Then, one end of the separator strip 41 contacts one side of the sedimentation plate, and the limiting block 62 is pressed to insert the insertion block 61 into the corresponding adjustment hole 43, thus fixing the separator strip 41 to the mounting block 55. At this time, the adjacent sedimentation plate is placed at the other end of the separator strip 41. In this way, the distance between adjacent sedimentation plates can be maintained to meet the requirements by the separator strip 41 of fixed size, and the operation is more convenient without relying on personal experience.

[0028] Furthermore, the constant temperature box 1, the placement frame 2, and the support frame 3 constitute the existing model GHP-9080 water-jacketed constant temperature incubator, and the placement frame 2 is the existing metal mesh plate frame.

[0029] Specifically, to facilitate the separation of adjacent sedimentation plates, the separating assembly 4 includes a separating strip 41 disposed at the top of the placement frame 2 for separating adjacent sedimentation plates, and contact rods 42 symmetrically disposed at both ends of the separating strip 41 for contacting the sedimentation plates. The separation strip 41 is placed between adjacent sedimentation plates to maintain the distance between them. The length of the separating strip 41 is set according to the actual needs of sedimentation plate placement and is a fixed length. Therefore, different lengths of separating strips 41 can be replaced according to usage requirements to ensure the distance between adjacent sedimentation plates.

[0030] More specifically, to reduce the impact on the settling plate: the end of the separator 41 is fixedly connected to the outer wall of the contact rod 42, and the horizontal cross-section of the contact rod 42 is circular. The contact between the contact rod 42 and the settling plate reduces the impact of the separator 41 on the settling plate. The contact area between the separator 41 and the contact rod 42 is bonded and fixed. At least four contact rods 42 are provided, located at the four corners at both ends of the separator 41. The circular shape of the contact rod 42 minimizes the contact area with the settling plate, thereby reducing the impact on the airflow along the edges of the settling plate.

[0031] Specifically, to facilitate adjustment of the position of the separator 41, an adjustment hole 43 is provided at the top of the separator 41 for adjusting its position, and a connector 6 is inserted into the adjustment hole 43. The position of the separator 41 is adjusted by inserting the connector 6 into the adjustment hole 43 at different positions. The size of the adjustment hole 43 is adapted to the size of the insert block 61. Multiple adjustment holes 43 are equally spaced along the straight direction of the separator 41. By inserting the insert block 61 into the adjustment hole 43 at different positions, the position of the separator 41 can be adjusted, facilitating support for the distance between adjacent sedimentation plates. Simultaneously, the orientation of the separator 41 and the mounting block 55 can be changed to separate the sedimentation plates in different directions.

[0032] Specifically, to facilitate the installation of the clamping assembly 5 and the placement frame 2: the clamping assembly 5 includes a fixed claw 51 and a movable claw 52 inserted inside the placement frame 2 for clamping the placement frame 2; a limiting plate 53 fixedly disposed at one end of the movable claw 52 to restrict the movement of the movable claw 52; a return spring 54 disposed on the side of the limiting plate 53 away from the movable claw 52 for pulling the limiting plate 53; and a mounting block 55 sleeved on the outside of the return spring 54 for slidingly inserting the movable claw 52. One end of the mounting block 55 is fixedly connected to one side of the fixed claw 51, and the other end of the mounting block 55 has a first insertion hole for slidingly inserting the movable claw 52. The interior of the mounting block 55 has a first cavity for installing the limiting plate 53 and the return spring 54, and the first insertion hole and the first cavity communicate with each other. By clamping the frame of the placement frame 2 with the fixed claw 51 and the movable claw 52 respectively, the movement of the clamping assembly 5 is restricted. Both the fixed claw 51 and the movable claw 52 have hook-shaped vertical sections. The fixed claw 51 is bonded and fixed to the mounting block 55 at the contact point, and the movable claw 52 is bonded and fixed to the limiting plate 53 at the contact point. The part of the movable claw 52 connected to the limiting plate 53 slides through the first through hole, and its size is adapted to the first through hole. The size of the limiting plate 53 is adapted to the size of the cavity. The size of the first through hole is smaller than the size of the cavity. Two return springs 54 are symmetrically arranged, located at the two ends of the limiting plate 53 away from the movable claw 52. The two ends of the return springs 54 are bonded and fixed to the limiting plate 53 and the inner wall of the cavity, respectively. When the movable claw 52 is pulled, the return spring 54 will be stretched, thereby generating a restoring force. By pulling the limiting plate 53, the force acts on the movable claw 52, ​​causing the movable claw 52 to tend to move towards the fixed claw 51. In this way, the fixed claw 51 and the movable claw 52 are used to hold the grid of the placement frame 2, and the placement frame 2 and the clamping assembly 5 are fixedly installed.

[0033] Specifically, to facilitate the installation of the separator assembly 4 and the clamping assembly 5: the connector 6 includes an insert 61 fixedly connected to the top of the mounting block 55 for insertion into the separator assembly 4, limiting blocks 62 symmetrically arranged on both sides of the insert 61 for limiting the vertical movement of the separator assembly 4, a baffle 63 fixedly arranged at one end of the limiting block 62 for limiting the movement of the limiting block 62, and a push spring 64 arranged on the side of the baffle 63 away from the limiting block 62 for pushing the baffle 63. The insert 61 has a second cavity inside for mounting the baffle 63 and the push spring 64, and the inner wall of the second cavity has a second insertion hole for inserting the limiting block 62. By pressing the limiting block 62, the separator 41 and the mounting block 55 can be quickly installed by inserting the insert 61 into the adjustment hole 43 or removing the insert 61 from the adjustment hole 43. The horizontal cross-section of the insert block 61 is rectangular, corresponding to the shape of the horizontal cross-section of the adjusting hole 43. The insert block 61 is bonded and fixed to the mounting block 55 at the contact point. The distance between the bottom end of the limiting block 62 and the top end of the mounting block 55 is adapted to the thickness of the partition strip 41. Two limiting blocks 62 are symmetrically arranged. The size of the second through hole is adapted to the size of the limiting block 62. The size of the second cavity is larger than the size of the second through hole. The size of the baffle 63 is 1.2 times the size of the second through hole. The contact point between the limiting block 62 and the baffle 63 is bonded and fixed. The push spring... 64 is positioned between the two baffles 63 on opposite sides. The push spring 64 is always in a compressed state within the second cavity. By pressing the limiting block 62, the insert block 61 is inserted into the adjustment hole 43. Under the restoring force of the push spring 64, the limiting block 62 is pushed out of the second insertion hole, thereby restricting the vertical movement of the separator 41 and completing the quick installation of the separator 41 and the mounting block 55. Similarly, by pressing the limiting block 62, the insert block 61 can be moved out of the adjustment hole 43, completing the quick removal of the separator 41 and the mounting block 55.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
