TECHNICAL FIELD
[0001] The utility model relates to experimental apparatus technical field, especially a kind of fixing device applied to box positioning. BACKGROUND
[0002] In the process of automatic sample handling in biochemical laboratory, frequent replacement of pipette tip is required. The quick and convenient replacement of tip box and its versatility play an important role in the automatic handling process. The existing tip box holder has a simple structure, with a placing groove on the top of the tip box holder. The tip box can be loaded to perform the operation of taking out the tip.
[0003] However, during normal operation, when the pipetting module inserts and takes out the tip from the tip box, the tip box will be dragged up along with the pipetting module due to the tip, causing the position of the tip box to change, which is not conducive to the subsequent insertion and removal of the tip. Even worse, the tip box may be detached from the tip holder, hindering the continuation of the subsequent process, and the use stability is poor. SUMMARY

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A fixing device applied to box positioning, comprising a fixing seat;
[0007] The top of the fixing seat is provided with a mounting groove for the tip box to sink into. One side of the mounting groove is provided with a first buckle member, and the opposite side of the mounting groove is provided with an elastic buckle member. The first buckle member and the elastic buckle member both have a limiting convex edge for buckling on the bottom skirt of the tip box.
[0008] In one of the possible implementations, the elastic buckle member is detachably connected with the fixing seat.
[0009] In one of the possible implementations, the fixing seat comprises:
[0010] A positioning plate, the mounting groove is provided on the positioning plate; and
[0011] A supporting leg connected to the bottom of the positioning plate, which supports the positioning plate.
[0012] In one of the possible implementations, the first buckle member is integrally provided with the positioning plate.
[0013] In one of the embodiments, the installation groove is provided with a relief gap for the elastic buckle to be inserted into the installation groove.
[0014] In one of the embodiments, the installation groove comprises two L-shaped fixing edges, which form a rectangular installation groove.
[0015] In one of the embodiments, the first buckle is provided with a plurality of buckles and is arranged on one of the fixing edges; the elastic buckle is provided with at least two buckles and is arranged on the other fixing edge.
[0016] In one of the embodiments, the elastic buckle is provided with two buckles and is arranged on both sides of the corner of the fixing edge.
[0017] In one of the embodiments, the supporting leg is provided with a counterweight.
[0018] The utility model discloses a fixing device for box body positioning, which has the following advantages:
[0019] When the fixing device is used, the fixing device is placed on the workbench, and the gun head box is inserted into the installation groove during use. During installation, the elastic buckle is directly pressed into the installation groove during installation, and the bottom skirt gradually presses the elastic buckle during the process of the gun head box entering the installation groove. When the bottom skirt completely enters the installation groove, the elastic buckle rebounds. At this time, the limiting convex edge of the first buckle and the elastic buckle is located above the bottom skirt, which limits the gun head box from being separated from the installation groove, thereby realizing the positioning and fixing effect. When the gun head box needs to be removed later, the gun head box is pushed as a whole, the bottom skirt presses the elastic buckle, the bottom skirt near the first buckle is separated first, and then the gun head box can be removed as a whole. The utility model provides a fixing device for box body positioning, which can position and fix the gun head box when the gun head is inserted and taken from the gun head box, and has the advantage of high use stability.
