Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the device comprises a positioning plate 1, a through hole 2, a horizontal bulb 3, a handle 4, a locking block 5, a nut sleeve 6, a heat-resisting ring 7, an adjusting screw 8, a spring 9, a vertical hole 10, a clamping plate 11 and a locking pin 12.

Example (b):

the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, fig. 2 and fig. 3, a novel viscometer bracket comprises a positioning plate 1, a horizontal bubble 3 is fixed on the positioning plate 1, when the positioning plate 1 is placed, the upper surface of the positioning plate 1 can be visually judged whether to be in a horizontal state through the horizontal bubble 3, the horizontal bubble 3 is also called a level meter, and for the prior art, the principle is not repeated in the embodiment.

A handle 4 is fixed on the positioning plate 1, and an operator can conveniently move the device by holding the handle 4. Use the through-hole 2 that supplies the viscometer to pass through and be used for fixed viscometer's locking mechanism on locating plate 1, locking mechanism includes latch segment 5 through bolted connection on locating plate 1, be equipped with vertical (meaning with 1 axial parallel direction) connecting hole in the latch segment 5, latch segment 5 internal fixation has the fitting pin 12 of horizontal setting, be equipped with on the fitting pin 12 with the vertical coincidence of connecting hole and the vertical bore 10 of intercommunication, both ends all are fixed with the heat-resisting ring 7 of polytetrafluoroethylene system about the fitting pin 12.

Transversely slidable connection has splint 11 in the fitting pin 12, and splint 11 is close to one side of vertical hole 10 and is fixed with the foam-rubber cushion, through the extrusion of foam-rubber cushion buffering splint 11 to the viscometer surface, threaded connection has adjusting screw 8 on the fitting pin 12, is fixed with spring 9 between adjusting screw 8 and the splint 11, and adjusting screw 8 is located the partial threaded connection outside the latch segment 5 and has nut cover 6.
