Description
Technical field
The present invention relates to sensor field, especially relate to a kind of microdisplacement guide piece for sensor.
Background technology
In present sensor field, hydrostatic level for example, general all is split type, that is: sensitive element packaging part, inner core, urceolus three-major-items, main cause is that inner core is that single-point is fixed in inside, inner core rocks the damage that causes spirit-leveling instrument easily in transportation, split type spirit-leveling instrument is assembled at engineering site, technological requirement is higher, is difficult to control, requires also higher relatively to the workmen.In addition, the spirit-leveling instrument of installation if there is the angle of inclination, because buoyancy makes progress all the time, so inner core can the relative tilt angle occur with spirit-leveling instrument under buoyancy, can influence measuring accuracy greatly.
Summary of the invention
Purpose of the present invention is exactly that a kind of simple in structure, precision is high, long-time stability are good microdisplacement guide piece is provided in order to overcome the defective that above-mentioned prior art exists.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of microdisplacement guide piece, comprise urceolus, inner core and last flexible member, described upward flexible member is located at the top of urceolus, the upper end of described inner core connects goes up flexible member, described guide piece also comprises flexible member down, this time flexible member is located at the bottom of urceolus, and the lower end of described inner core connects flexible member down.
The described flexible member of going up is connected with the inwall of urceolus with following flexible member.
The described flexible member of going up is corrugated plate or sheet metal with following flexible member.
The described flexible member of going up offers mesh with following flexible member.
Described inner core is interior empty tube or rod member.
The shape of described urceolus comprises circle, square or hexagon.
Compared with prior art, the present invention utilizes the characteristic of flexible member, by the fixing inner core of two flexible members up and down, prevent the displacement of inner core on the inoperative direction, in the transportation, inner core is supported by two flexible members, the situation that double swerve can not occur, make it not fragile, can make product be packaged into one, without assembled in situ.

Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of microdisplacement guide piece comprises urceolus 3, inner core 4, goes up flexible member 1 and following flexible member 2.Last flexible member 1 and following flexible member 2 general employing corrugated plate or sheet metals, flexible member 2 offer mesh on it, make flexible member 2 be the filter screen shape.Last flexible member 1 and following flexible member 2 are located at the upper and lower of urceolus 3 respectively, and be connected with urceolus 3 inwalls, the two ends up and down of inner core 4 are fixing by last flexible member 1 and following flexible member 2 respectively, by 2 fixing modes, prevent the displacement of inner core 3 on the inoperative direction, improve measuring accuracy, and can make it in transportation, prevent double swerve, reduce and damage.
Empty tube or rod member in wherein inner core 3 can be selected according to different sensors, and urceolus 3 can adopt circular outer cylinder, the inwall in its cross section can be according to using needs to be designed to circular shown in Fig. 4～6, square or hexagon, and outer wall is rounded, and its side as shown in figure 11.
The principle of work of spirit-leveling instrument is that the liquid levels in the urceolus 4 change and change the suffered buoyancy of inner core 3, the buoyancy variation is operated on the sensitive element 5, change the output data of sensitive element 5, thereby obtained the variable quantity of liquid level, also just obtained the sedimentation situation of spirit-leveling instrument position.Because buoyancy makes progress all the time, when using traditional hydrostatic level of employing single-point fixed form as shown in Figure 2, spirit-leveling instrument occurs tilting, and inner core 3 skew can occur under buoyancy function, last flexible member 1 undercapacity can influence measuring accuracy greatly to keep the vertical of inner core 3.In addition, in transportation, inner core 3 can be under gravity and external force effect, and double swerve very easily damages spirit-leveling instrument.
Fig. 3 is for adopting the structural representation of hydrostatic level of the present invention, increased a following flexible member 2 in the bottom of inner core 3, avoided under the gravity and external force effect of inner core 3 when spirit-leveling instrument occurs tilting or transport, the displacement of other inoperative directions appears in inner core 3, realized the guiding to displacement, made its precision raising and not fragile.
A kind of microdisplacement guide piece, the urceolus of this device are square urceolus, and the inwall in its cross section can be according to using needs be designed to as Fig. 7 or shown in Figure 8 square or circular, and outer wall is square, its side as shown in figure 11, remainder is with embodiment 1.
A kind of microdisplacement guide piece, the urceolus of this device are the hexagon urceolus, and the inwall in its cross section can be according to using needs be designed to as Fig. 9 or circle shown in Figure 10 or hexagon, and outer wall is hexagon, its side as shown in figure 12, remainder is with embodiment 1.
Urceolus shape of the present invention is not limited to the structure of Fig. 4～10 illustrated embodiment, and the inner and outer wall in urceolus cross section all can adopt circle or other polygons.
