[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figures 1-3 , an embodiment provided by the present utility model: an adjustable kit placement rack, including a test bench 1, a support column 2 is detachably installed at the top end of the test bench 1. The support column 2 mainly supports and connects the entire placement rack 3. A placement rack 3 is arranged on the inner side wall of the support column 2. A fixed block 4 is fixedly connected to the side wall of the placement rack 3. The bottom inner wall of the support column 2 is elastically connected to a wedge block 5 through a return spring 15. The wedge block 5 has an inclined surface. When the inclined surface is squeezed, the wedge block 5 will slide along the inner wall of the support column 2. Refer to Figure 3 And Figure 4 , a connection mechanism is arranged at the right end of the wedge block 5. An L-shaped groove 9 is opened on the right side wall of the support column 2. The L-shaped groove 9 has a vertical opening and a horizontal opening. The initial state of the positioning block 8 coincides with the vertical opening of the L-shaped groove 9, allowing the positioning block 8 to move vertically along the L-shaped groove 9. After the positioning block 8 coincides with the horizontal opening, the entire fixing plate 7 cannot move downward.

[0033] Refer to Figures 5-6, a sliding connection is provided between the inner wall of the placement rack 3 and an extension rack 10. Through the extension rack 10, more test kits of the same batch can be placed. The inner wall of the top end of the extension rack 10 is elastically connected to a round tube 12 through a positioning spring 11. A pressing plate 13 is slidably connected through the inner wall of the extension rack 10. The extension rack 10 is provided with corresponding notches, enabling the pressing plate 13 to move vertically along the notches. A guide tube 14 is fixedly connected to the inner wall of the extension rack 10. The guide tube 14 allows the pressing plate 13 to move vertically without deviation in its movement trajectory. The inner wall of the top end of the extension rack 10 is fixedly connected to one end of the positioning spring 11. When the round tube 12 moves downward, it compresses the positioning spring 11. When resetting, the elastic force of the positioning spring 11 is used to drive the round tube 12 to reset. The other end of the positioning spring 11 is fixedly connected to the bottom end of the round tube 12. The round tube 12 is slidably connected to the inner wall of the extension rack 10. The extension rack 10 is provided with a notch corresponding to the round tube 12, enabling the round tube 12 to move vertically. The pressing plate 13 is slidably connected to the outer wall of the guide tube 14. The round tube 12 is inserted into the inner wall of the placement rack 3. As Figure 5 shown, the placement rack 3 is provided with a plurality of notches corresponding to the round tube 12, enabling the round tube 12 to be inserted into it to limit the position of the entire extension rack 10.

[0034] Referring to Figures 1-3 , the inner wall of the bottom end of the support column 2 is fixedly connected to one end of a reset spring 15. When the wedge block 5 moves upward, it compresses the reset spring 15. When resetting, the elastic force of the reset spring 15 is used to drive the wedge block 5 to reset. The other end of the reset spring 15 is fixedly connected to the top end of the wedge block 5. The wedge block 5 is slidably connected to the inner wall of the support column 2. The outer wall of the wedge block 5 contacts the outer wall of the fixed block 4. The fixed block 4 is inserted into the inner wall of the support column 2. The connecting mechanism includes a connecting rod 6, and the main function of the connecting rod 6 is to connect the wedge block 5 and the fixing plate 7. The connecting rod 6 is fixedly connected to the side wall of the wedge block 5. The right end of the connecting rod 6 is fixedly connected to a fixing plate 7. A positioning block 8 is slidably connected through the inner wall of the fixing plate 7. The fixing plate 7 is provided with a notch to satisfy the lateral movement of the positioning block 8. The connecting rod 6 is slidably connected through the inner wall of the support column 2. The support column 2 is provided with a notch, enabling the connecting rod 6 to slide vertically along the inner wall of the support column 2. The positioning block 8 is clamped on the inner wall of the L-shaped groove 9.

[0035] Working principle: When it is necessary to disassemble the placement rack 3, only need to move the positioning block 8 upwards with the fixed plate 7, the connecting rod 6 and the wedge block 5 and compress the return spring 15. When the wedge block 5 does not block the fixed block 4 from moving out horizontally from the inner wall of the support column 2, move the positioning block 8 to the right so that the positioning block 8 coincides with the horizontal opening of the L groove 9. Use the reverse elastic force of the return spring 15 to keep the positioning block 8 stuck in the horizontal opening of the L groove 9. Then move the placement rack 3 and the fixed block 4 outwards to separate the fixed block 4 from the inner wall notch of the support column 2. Finally, move the positioning block 8 to the left to separate the positioning block 8 from the horizontal opening of the L groove 9 and make the positioning block 8 coincide with the vertical opening of the L groove 9. At this time, release the positioning block 8 and use the reverse elastic force of the return spring 15 to move downwards and reset adjacent to the wedge block 5, the connecting rod 6, the fixed plate 7 and the positioning block 8, so that the wedge block 5 blocks the inner wall notch of the support column 2.

[0036] When it is necessary to install the placement rack 3, only need to align and snap the fixed block 4 into the inner wall notch of the support column 2. At the same time, the outer wall of the fixed block 4 will squeeze the inclined surface of the wedge block 5, so that the wedge block 5 drives the connecting rod 6 and the fixed plate 7 to move upwards with the positioning block 8. When the wedge block 5 and the fixed block 4 are no longer in contact, use the reverse elastic force of the return spring 15 to drive the wedge block 5, the connecting rod 6, the fixed plate 7 and the positioning block 8 to reset downwards, so that the wedge block 5 blocks the fixed block 4 and makes the fixed block 4 unable to move out horizontally from the inner wall notch of the support column 2, thus completing the entire disassembly and assembly process of the placement rack 3.

[0037] When it is necessary to increase the usage area of the placement kit, only need to press down the pressing plate 13 to drive the round tube 12 to move downwards with the pressing plate 13 and compress the positioning spring 11, so that the round tube 12 enters the inner wall of the extension rack 10 and separates the round tube 12 from the notch of the placement rack 3. Then pull out the extension rack 10 outwards to adjust the placement space pulled out by the extension rack 10 according to the placement requirements. When limiting is needed, only need to release the pressing plate 13 and use the reverse elastic force of the positioning spring 11 to drive the round tube 12 and the pressing plate 13 to reset, so that the round tube 12 is inserted into the notch of the placement rack 3, thus completing the adjustment of the entire extension rack 10. When not in use, the above steps can be operated to make the extension rack 10 retract into the inner wall of the placement rack 3.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
