[0038] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0039] Reference Figures 1 to 4 As shown, a vascular endothelial growth factor detection reagent storage box according to an embodiment of the present invention includes: a box body 100, a box cover 200, a storage portion 300, and a lifting frame 500.

[0040] A placement cavity 101 is provided in the box body 100 . Obviously, the top of the placement cavity 101 is open.

[0041] The box cover 200 is arranged at the top of the box body 100 to open and close the placement cavity 101. Specifically, the box cover 200 is rotatably arranged at the top of the box body 100. For the convenience of transportation, a snap-fitting part can be provided between the box body 100 and the box cover 200 to connect the box body 100 and the box body 100. This is the prior art and will not be elaborated on here.

[0042] The storage portion 300 is disposed in the placement cavity 101. A plurality of groups of placement holes 301 are provided at intervals in front and back of the storage portion 300. A group of placement holes 301 includes a plurality of placement holes 301 spaced apart in the left and right directions. The placement holes 301 are vertically penetrated and are penetrated by reagent tubes 400. A spacing is left between the lower end surface of the storage portion 300 and the bottom wall of the placement cavity 101.

[0043] Each group of placement holes 301 is provided with a corresponding lifting rack 500, that is, the number of lifting racks 500 is the same as the number of groups of placement holes 301, and the lifting racks 500 are arranged on the box body 100 in a lifting and adjusting manner, and the lifting racks 500 include support plates 510 distributed on the left and right, and the support plates 510 are located on the lower side of the storage part 300. The placement holes 301 of the same group are all located on the upper side of the corresponding support plates 510, and the support plates 510 are used to support all reagent tubes 400 that are inserted into the placement holes 301 of the same group. Obviously, when the lifting racks 500 are adjusted upward, all reagent tubes 400 in the placement holes 301 of the same group can be driven to rise synchronously through the support plates 510, and when the lifting racks 500 are adjusted downward, the reagent tubes 400 can also move downward under gravity or the downward pressure of the operator. It should be noted that in the storage state without taking the reagent tubes 400, the height of any lifting rack 500 is consistent.

[0044] The vascular endothelial growth factor detection reagent storage box of the embodiment of the utility model, when it is necessary to take out the reagent tube 400, first open the box cover 200, determine the position of the placement hole 301 through which the required reagent tube 400 is inserted, then find the lifting frame 500 corresponding to the placement hole 301, and adjust the corresponding lifting frame 500 to make the reagent tube 400 in the group of placement holes 301 corresponding to the lifting frame 500 rise and be higher than other reagent tubes 400. At this time, there will be no obstructions on the front and back sides of the top of the lifted reagent tube 400, and the operator can clamp the required reagent tube 400 from the front and back directions, so the operating space is greatly improved, and it is very convenient to take out the reagent tube 400.

[0045] Reference Figures 1 to 4As shown, it can be understood that the lifting frame 500 is vertically slidably installed on the box body 100. The lifting frame 500 has at least a first position and a second position during the vertical sliding process. The second position is higher than the first position. An elastic member and a limiting member are provided between the box body 100 and any lifting frame 500. The limiting member is used to limit the upward displacement of the lifting frame 500 when the lifting frame 500 is in the first position, and the limiting member can release the limit of the lifting frame 500; the elastic member is used to apply an upward elastic force to the lifting frame 500; when the lifting frame 500 is in the first position, the limiting member can limit the upward displacement of the lifting frame 500 and the elastic member applies an upward elastic force to the lifting frame 500, and the two reach a balance to position the lifting frame 500 in the first position, and when the limiting member releases the limit of the lifting frame 500, the elastic member applies an elastic force to the lifting frame 500. The lowering rack 500 is used to push the lifting rack 500 from the first position to the second position, thereby pushing the reagent tubes 400 in a group of placement holes 301 corresponding to the lifting rack 500 to move upward; in this embodiment, in the storage state, that is, when there is no need to take the reagent tubes 400, the lifting rack 500 is in the first position, and the box cover 200 can be closed normally at this time. When it is necessary to take the reagent tubes 400, the box cover 200 is opened, the corresponding lifting rack 500 is found, and the limiter corresponding to the lifting rack 500 is released. The lifting rack 500 is pushed up to lift the reagent tube 400 under the action of the elastic member, and then the operator can take the required reagent tube 400. After taking it, the lifting rack 500 is pressed down to the first position, and the limiter is made to re-limit the lifting rack 500 to position the lifting rack 500 in the first position, which is very convenient to use. It should be noted that when the lifting rack 500 is in the first position, the upper and lower ends of the reagent tube 400 extend out of the storage portion 300.

[0046] Reference Figures 1 to 4 As shown, it can be understood that the elastic member is set as a compression spring 600, which has a simple and practical structure. In some specific embodiments, a plurality of compression springs 600 are arranged at intervals on the left and right. The compression springs 600 are vertically distributed and the two ends thereof respectively abut against the bottom surface of the support plate 510 and the bottom wall of the placement cavity 101 to apply an upward elastic force to the lifting frame 500. The provision of a plurality of compression springs 600 can make the lifting frame 500 more uniformly stressed, thereby increasing the stability and reliability of the structure. In a further embodiment, a first mounting column 511 is provided on the bottom surface of the support plate 510, and a second mounting column 102 is provided on the bottom wall of the placement cavity 101. The upper and lower ends of the compression spring 600 are respectively sleeved on the first mounting column 511 and the second mounting column 102. The first mounting column 511 and the second mounting column 102 can respectively provide installation positions and guides for the compression spring 600, thereby increasing the stability of the compression spring 600 when deformed, and having strong practicality.

[0047] Reference Figures 1 to 4As shown, it can be understood that the lifting frame 500 also includes a first side plate 520, which is vertically fixed to one end of the support plate 510 in the length direction and extends to the upper side of the storage portion 300. It can be understood that a gap is left between the side of the storage portion 300 and the cavity wall of the placement cavity 101 for the first side plate 520 to pass through; the top of the first side plate 520 is provided with an abutment block 521 extending horizontally to the outside of the box body 100, and the limiter is set as a snap ring 700, which is a ring-shaped structure. The ring 700 is hinged to the outer wall of the box body 100, and the snap ring 700 is configured as follows: when the lifting frame 500 is in the first position, the snap ring 700 can be rotated to be sleeved on the abutment block 521 to block the upward movement path of the abutment block 521 and thus limit the upward displacement of the abutment block 521. Obviously, the snap ring 700 can also be rotated to be separated from the abutment block 521 to avoid the vertical movement path of the abutment block 521, that is, to release the vertical limit of the lifting frame 500. With the above arrangement, the structure is simple and easy to use. It can be understood that when the lifting frame 500 is in the first position, the first side plate 520 and the abutment block 521 do not protrude upward from the box body 100; in addition, the side wall of the box body 100 is provided with an avoidance groove 104 for the abutment block 521 to pass through.

[0048] Reference Figures 1 to 4 As shown, it can be understood that the hinge axis of the clamping ring 700 is distributed front and back and its hinge position is located at the lower side of the abutment block 521, that is, when the clamping ring 700 is needed to limit the upward displacement of the abutment block 521, the clamping ring 700 is flipped up so that the clamping ring 700 is sleeved on the abutment block 521 to hook the abutment block 521. With this arrangement, the force is reasonable. In a further embodiment, an embedding groove 522 is provided on the upper end surface of the abutment block 521 for partially embedding the snap ring 700. By providing the embedding groove 522 for partially embedding the snap ring 700, it is possible to prevent the snap ring 700 from being easily separated from the abutment block 521 when the snap ring 700 is used to limit the abutment block 521. When it is necessary to release the limit on the lifting frame 500, the abutment block 521 is first pressed down to disengage the snap ring 700 from the embedding groove 522, and then the snap ring 700 is rotated to separate from the abutment block 521; wherein, the cross-section of the snap ring 700 is circular, and the snap ring 700 includes a hinged portion, an embedding portion and two intermediate connecting portions, both of which extend forward and backward, and the two intermediate connecting portions are used to connect the hinged portion and the embedding portion to form an annular structure, the hinged portion is hinged to the outer wall of the box body 100, and the embedding portion is used to embed the embedding groove 522, and the embedding groove 522 extends forward and backward and has a semicircular cross-section.

[0049] Reference Figures 1 to 4As shown, it can be understood that the lifting frame 500 also includes a second side plate 530, which is vertically fixed to one end of the support plate 510 away from the first side plate 520, that is, the first side plate 520 and the second side plate 530 are respectively fixed to the left and right ends of the support plate 510, and the left and right sides of the placement cavity 101 are provided with vertically extending slide grooves 103, and the slide grooves 103 on both sides are respectively slidably matched with the first side plate 520 and the second side plate 530 to slide and install the lifting frame 500, which has a simple structure and is stable and reliable. Specifically, the widths of the support plate 510, the first side plate 520, and the second side plate 530 are all the same as the width of the slide groove 103. Further, the top opening of the slide groove 103 is set to allow the lifting frame 500 to be loaded or taken out, and the storage portion 300 is detachably arranged in the box body 100 to facilitate the disassembly and assembly of the lifting frame 500 and the elastic member, and the storage portion 300 and the box body 100 can both be made of plastic material, and the two can be connected by fasteners.

[0050] Reference Figures 1 to 4 As shown, it can be understood that a protective pad 201 is provided at the inner end of the box cover 200. When the box cover 200 is closed and the lifting frame 500 is in the first position, the lower end surface of the protective pad 201 abuts against the reagent tube 400, thereby preventing the reagent tube 400 from moving vertically and playing a protective role.

[0051] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
