Abstract
The utility model relates to an instrument or an equipment positioning device, in particular to a locking device for the installation and the accurate position of an analytical instrument. The utility model has a simple structure, compactness, a few components, simple and easy installation and operation and accurate and reliable position. The utility model comprises a handle, a rotating shaft structure and a main shaft structure, the handle is fixed and connected with the rotating shaft structure, the rotating shaft structure is a column bar or a round ball, two sides of the rotating shaft are milled flat with two sections of circular arcs retained; the main shaft structure is a guiding slot, from which two sides of the milling plane of the rotating shaft pass, and an accommodating slot, which can cooperate with the rotating shaft structure and rotate along with the rotating shaft structure around an axis.
Description
Technical field
The utility model relates generally to the positioning device of instrument, equipment, the especially installation of analytical instrument and the accurately locking device of location.
Background technique
In biology, chemical experiment and medical equipment, reagent dish and sample disk often need fixedly mount from equipment and dismantle, and the Location accuracy to reagent dish and sample disk has higher requirement when mounted, promptly need to satisfy reagent dish and sample disk fitting operation simply, requirement accurately.In present prior art, positioning means and locking mechanism are generally two-part, operation respectively, and integrated operation structure inconvenience can not realize the two-in-one of installing and locating and locking, and part mostly is machine and adds part, has the high shortcoming of processing cost.
Summary of the invention
The purpose of this utility model provides a kind of novel locking device, and to overcome above-mentioned defective, implementation structure is simple, compact, number of parts is few, and is simple and convenient during fitting operation, and accurate positioning, reliable.
The technical solution of the utility model is a kind of locking device, comprises handle, turning shaft structure, main shaft structure, and handle is fixedlyed connected with turning shaft structure, and its special way is that described turning shaft structure is the cylindrical rod that two sections circular arcs were put down and kept in one or two side milling; Described main shaft structure be one can only make guiding groove that turning shaft structure both sides milling flat passes through with and can cooperate turning shaft structure down, make the containing groove of turning shaft structure along its axis rotation.
Described solid member can be the cylindrical rod that symmetrical two milling flats are arranged.
Described solid member can be the ball that symmetrical two milling flats are arranged.
Described locking device, the two side of its guiding groove can be the plane.
Described locking device, the bottom land of its containing groove are cambered surface.
Adopt the locking device of above structure, it is simple in structure, compact, number of parts is few, and is simple and convenient during fitting operation, and accurate positioning, reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model locking device.
Fig. 2 is the partial enlarged drawing of Fig. 1 I.
Fig. 3, Fig. 4, Fig. 5 are the use scheme of installations of the utility model locking device.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
The utility model locking device comprises handle 1, turning shaft structure 2, main shaft structure 3, and handle 1 is fixedlyed connected with turning shaft structure 2, and turning shaft structure is the cylindrical rod 2 that two sections circular arcs were put down and kept in one or two side milling, also can be the ball that symmetrical two milling flats are arranged; Main shaft structure 3 is that a guiding groove 4 and the guiding groove that cylindrical rod 2 both sides milling flats are passed through can cooperate cylindrical rod 24 times, make the containing groove 5 of cylindrical rod 2 along its axis rotation; The two side 6 of its guiding groove 4 can be the plane, and the bottom land 7 of its containing groove 5 can be cambered surface.
Using process sees also Fig. 3, Fig. 4, Fig. 5, and cylindrical rod 2 is by handle 1 control, and when handle 1 was dug, mechanism was in opening state, and cylindrical rod 2 is by guiding groove 4; Then, rotating handles 1, cylindrical rod 2 rotate thereupon, and cylindrical rod 2 changes with the guiding groove 4 of main shaft structure 3 and the surface of contact of containing groove 5, and when handle 1 forwarded horizontal positioned to, cylindrical rod 2 was stuck in guiding groove 4 places, and mechanism is in locking states.
