Abstract
The utility model relates to the technical field of pipettors, in particular to a quick assembling, disassembling and connecting structure for a piston and a connecting sleeve of a high-precision electrical pipettor. The quick assembling, disassembling and connecting structure comprises a piston main body and the connecting sleeve; a connecting part is arranged at the top of the piston main body; a conical head is arranged at the top of the connecting part in a protruding manner; a conical clamping groove, which corresponds to and is matched with the conical head, is formed inside the connecting sleeve; and the conical head is clamped in the conical clamping groove. When the quick assembling, disassembling and connecting structure is assembled, all that is needed is to press the conical head of the piston main body into the connecting sleeve to clamp the conical head in the conical clamping groove, and the piston main body can be connected onto the connecting sleeve; while the quick assembling, disassembling and connecting structure is disassembled, all that is needed is to pull the piston main body downwards with great effort to pull out the conical head from the conical clamping groove, and the piston main body can be separated from the connecting sleeve smoothly, without using tools. Therefore, the quick assembling, disassembling and connecting structure has the advantages that the assembly and the disassembly are convenient and quick, and the efficiency is high.
Description
Technical field:
The utility model relates to the pipettor technical field, relates in particular to the quick mounting or dismounting syndeton of electronic pipettor piston of a kind of high accuracy and adapter sleeve.
Background technology:
In medical treatment, medicine, gene and protein research, biological study, drug development laboratory and other biological technology application; Often need utilize pipettor in various laboratory operation rules, to come handle laboratory; It utilizes pipettor that the liquid of certain volume is sucked in the pipette, then liquid is distributed into one or more dispensed volume.Existing electronic pipettor generally be that output at motor is connected with adapter sleeve, motor moves up and down through the adapter sleeve driven plunger, but piston and adapter sleeve are for being rigidly connected; Generally be to be locked,, be difficult to tool using piston is carried out installation and removal because electronic pipettor inner space is very little through screw; Often need complete machine be taken apart and could operate; The piston mounting or dismounting are inconvenient, waste time and energy, and efficient is low.
The utility model content:
The purpose of the utility model be exactly the deficiency that exists to prior art and provide a kind of and can install and remove fast, the quick mounting or dismounting syndeton of the electronic pipettor piston of simple load and unload high accuracy and adapter sleeve.
To achieve these goals, the technical scheme of the utility model employing is:
The quick mounting or dismounting syndeton of electronic pipettor piston of high accuracy and adapter sleeve; It includes piston main body, adapter sleeve; The top of piston main body is provided with connecting portion; The top of connecting portion convexes with conical head, and adapter sleeve inside offers the taper draw-in groove with the conical head corresponding matching, and conical head is fastened in the taper draw-in groove.
Clearance groove is radially offered in the bottom of said adapter sleeve, and clearance groove is divided at least 2 resilient clamp portions with the bottom of adapter sleeve.
Said resilient clamp quality award from the ministry is elected 2 as.
The maximum outside diameter of said conical head is greater than the diameter of connecting portion.
The tapering of said conical head is 50～80 degree.
The tapering of said conical head is preferably 67 degree.
The utility model beneficial effect is: the utility model includes piston main body, adapter sleeve, and the top of piston main body is provided with connecting portion, and the top of connecting portion convexes with conical head, and adapter sleeve inside offers the taper draw-in groove with the conical head corresponding matching; Conical head is fastened in the taper draw-in groove, during installation, only needs the conical head of piston main body is compressed into adapter sleeve; Conical head is fastened in the taper draw-in groove can be connected piston main body on the adapter sleeve, during dismounting, firmly spurs piston main body downwards; Conical head is pulled out from the taper draw-in groove, can smoothly piston main body and adapter sleeve be separated, do not need tool using; Mounting or dismounting are convenient, can install and remove fast, and efficient is high.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the cut-away view of the utility model.
Fig. 3 is the decomposing schematic representation of the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described; See shown in Fig. 1～3, the quick mounting or dismounting syndeton of electronic pipettor piston of high accuracy and adapter sleeve, it includes piston main body 1, adapter sleeve 2; The top of piston main body 1 is provided with connecting portion 11; The top of connecting portion 11 convexes with conical head 12, and adapter sleeve 2 inside offer the taper draw-in groove 24 with conical head 12 corresponding matching, and conical head 12 is fastened in the taper draw-in groove 24.The maximum outside diameter of conical head 12 is greater than the diameter of connecting portion 11.The tapering of conical head 12 is 50～80 degree, and the tapering of conical head 12 is 67 degree in this embodiment.
Clearance groove 21 is radially offered in the bottom of adapter sleeve 2; Clearance groove 21 is divided at least 2 resilient clamp portions 22 with the bottom of adapter sleeve 2; Elasticity clamping part 22 is 2 in this embodiment; Resilient clamp portion 22 can strain, makes to form non-rigid the connection between piston main body 1 and the adapter sleeve 2, has the strain space.
During installation, only need the conical head 12 of piston main body 1 is compressed into adapter sleeve 2, conical head 12 is fastened in the taper draw-in groove 24 can be connected piston main body 1 on the adapter sleeve 2; During dismounting, firmly spur piston main body 1 downwards, conical head 12 is pulled out from taper draw-in groove 24; Can smoothly piston main body 1 and adapter sleeve 2 be separated, not need tool using, mounting or dismounting are convenient; Can install and remove fast, efficient is high.
Certainly, the above only is the preferred embodiment of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
