Abstract
The utility model relates to a pin and positioning sleeve matching device for a PCR (polymerase chain reaction) instrument. The pin positioning sleeve matching device overcomes the defect of inconvenience in mounting and demounting of existing devices and comprises a positioning sleeve and a pin. The positioning sleeve comprises a cylindrical positioning sleeve body, a cylindrical pin cavity and a thread through hole are communicated and arranged in the positioning sleeve body, and a chamfer is arranged at the joint of the pin cavity and the thread hole. A pin body of the pin comprises a cone frustum portion and a cylindrical portion which is provided with a thread blind hole and peripherally provided with an annular protrusion. The outer diameter of the cylindrical portion of the pin is matched with the inner diameter of the pin cavity of the positioning sleeve, the cylindrical portion of the pin and the pin cavity are in slidable fit and positioned through the annular protrusion. The pin and positioning sleeve matching device is simple in structure, the requirement on positioning and matching of the two parts can be met, the positioning sleeve and the pin are convenient to position, match, mount and demount, and interchangeability among different parts can be realized.
Description
Technical field
The utility model relates to a kind of adapting device, specifically a kind of PCR instrument bearing pin and setting sleeve adapting device.
Background technique
The PCR instrument has another name called gene-amplificative instrament, Thermal Cycler, but but be actually a kind of temperature cycler of precise temperature control of quick changeable temperature of control able to programme, be the indispensable indispensable instrument of life science and teaching field.PCR instrument main structure commonly used is comprised of main frame and modular unit at present, wherein the working procedure of main frame major control module temperature cycles.In actual applications, modular unit need to satisfy the use of different series specification test tube, therefore has the modular unit of corresponding different size on same main frame.So require its energy for convenience detach when need to be engaged in the modular unit location on the main frame.And at present, the connection orientation type of two two component that relatively do not move generally is to be threaded connection or alignment pin realizes, but the drawback of this mode maximum is installed and removed inconvenience exactly.But frequent modular unit possibly on the same main frame at present the PCR instrument is used, original mode will be brought very large difficulty to client's operation.
Summary of the invention
The utility model provides a kind of PCR instrument bearing pin and setting sleeve adapting device for the deficiencies in the prior art.
The utility model comprises setting sleeve and bearing pin.
Described setting sleeve comprises columniform setting sleeve body, and what be communicated with in the setting sleeve body has cylindrical bearing pin chamber and a tapped through hole, and bearing pin chamber and tapped hole joint are provided with chamfering.
The bearing pin body of described bearing pin is round platform part and column part, and column part has tapped blind hole, and column part is provided with annular protrusion along circumference.
The internal diameter coupling in the bearing pin chamber of the external diameter of the column part of bearing pin and setting sleeve, the column part of bearing pin and bearing pin chamber are slidingly matched, and locate by annular protrusion.
The utility model is simple in structure, can realize that two location between the part cooperate requirement, and the location of setting sleeve and bearing pin cooperates easy accessibility, can realize the interchangeability between the different parts.
Description of drawings
Fig. 1 is the structural representation of setting sleeve in the utility model;
Fig. 2 is the structural representation of bearing pin in the utility model;
Fig. 3 is the structural representation after setting sleeve and bearing pin are installed.
Embodiment
A kind of PCR instrument bearing pin and setting sleeve adapting device comprise setting sleeve and bearing pin.
As shown in Figure 1, setting sleeve comprises columniform setting sleeve body 1, the 1 interior connection of setting sleeve body have cylindrical bearing pin chamber 3 and a tapped through hole 2, bearing pin chamber 3 is provided with chamfering 4 with tapped hole 2 joints.
As shown in Figure 2, the bearing pin body of bearing pin is round platform part 5-1 and column part 5-2, and column part 5-2 has tapped blind hole 7, and column part is provided with annular protrusion 6 along circumference.
The internal diameter coupling in the external diameter of the column part 5-2 of bearing pin and the bearing pin chamber 3 of setting sleeve, column part 5-2 and the bearing pin chamber 3 of bearing pin are slidingly matched, and by annular protrusion 6 location.
By tapped through hole 2 setting sleeve is fixed on the main frame with screw, modular unit is fixed on the bearing pin by tapped blind hole 7, when modular unit and main frame assembling, its bearing pin is inserted in the bearing pin chamber 3, because certain tolerance fit gap is arranged between setting sleeve and the bearing pin, so bearing pin can move around in the bearing pin chamber 3 of setting sleeve, when bearing pin moved forward to annular protrusion 6 and runs into setting sleeve, main frame and setting sleeve just can be located fixing.If change other modules, the bearing pin of former modular unit can be pulled out from setting sleeve, insert again the new modular unit that has connected bearing pin.
