Description
Technical field
The utility model is related to project cost apparatus correlative technology field, more particularly to a kind of portable project cost
With spirit level holder.
Background technology
Spirit level is commonly used instrument in project cost in-site measurement, is to establish horizontal line of sight to measure ground point-to-point transmission
The instrument of height difference, general and levelling staff (Sopwith staff) are used cooperatively, and on ground, point-to-point transmission disposes spirit level, observation to be erected at 2 points
On levelling staff, by ruler reading calculate point-to-point transmission height difference.Spirit level is generally fixed to measure on holder, holder
Stability and operability directly affect the measurement accuracy of spirit level, and current existing spirit level weight support frame is big, supporting rod
It needs to adjust separately when being not easy to shrink and put, it is also extremely inconvenient to carry, and the supporting rod bottom of spirit level is generally arranged
For taper, purpose is primarily to convenient in the ground survey with sandstone or soil, but on the ground of smooth planar
Stability is bad when upper measurement, is easy to skid, falls down instrument.
Utility model content
The problems of middle spirit level holder for the above-mentioned prior art, the utility model provide a kind of structure conjunction
The project cost that reason, strong applicability, stability are good, are convenient for carrying spirit level holder.
The technical problems to be solved in the utility model is adopted the technical scheme that：Project cost spirit level holder, packet
Include spirit level installation threaded rod, stand base, several section supporting rods of stand base bottom flexible connection and interior extension bar, holder
Horizontal bubble is provided on pedestal, spirit level installs threaded rod top and stand base, spirit level installation threaded rod side is passed through to set
It is equipped with thread groove and is engaged with the gear for the lifting handle being arranged in stand base, contraction fixed card buckle is provided on supporting rod,
The other end of one end of extension bar in the inside flexible connection of the supporting rod, the interior extension bar is connected to spirit level installation threaded rod
The screw-pinch of lower part is buckled, and supporting rod bottom is connected with vacuum cup, and the side of the vacuum cup is provided with the vertex of a cone.
Further, supporting rod bottom connects vacuum cup by universal joint.
Further, spirit level installation threaded rod upper end is connected with steering base.
The utility model compared with prior art, 1, by the way that the vacuum cup that can turn to is arranged, it is applied widely, can
It is measured in sandstone dirt floor, and can guarantee the stability on smooth earth；2, retractable operation is simple while holder, both may be used
It reduces transport or carries area occupied, ensure that reliability when in use；3, the test of other general-purpose interfaces can be connected
Instrument, such as level meter, use scope are more extensive.

Specific implementation mode
In order to enable those skilled in the art to better understand the technical solutions of the present invention, it combines and has below according to attached drawing
The utility model is described in further detail in body embodiment.
As shown in Figure 1, 2, 3, project cost spirit level holder, including spirit level install threaded rod 2（Its top is
Spirit level general-purpose interface）, stand base 4, stand base bottom flexible connection several section supporting rods 9 and interior extension bar 10, branch
Horizontal bubble 3 is provided on frame pedestal, spirit level installs threaded rod top and stand base, spirit level is passed through to install threaded rod side
It is provided with thread groove 14 and is engaged with the gear 13 for the lifting handle 5 being arranged in stand base（It can pass through setting after adjustment height
The lifting fixed knob 6 of spirit level installation threaded rod other side corresponding position fixes spirit level and installs threaded rod in stand base
Position）, screw-pinch button is used to fix the lower end of spirit level installation threaded rod, is provided on supporting rod and shrinks fixed card buckle 8
（Supporting rod may be configured as several sections, shrink fixed card buckle by opening and closing to adjust the length of supporting rod）, the support
One end of extension bar in the inside flexible connection of bar, the other end of the interior extension bar are connected to the spiral shell of spirit level installation threaded rod lower part
Rotation is shunk on button 7, and supporting rod bottom is connected with vacuum cup 11（Vacuum switch itself is carried, is not drawn into figure）, described
The side of vacuum cup is provided with the vertex of a cone 12.
Preferably, in order to make supporting rod have better stability, supporting rod bottom on the ground with sandstone or soil
Vacuum cup is connected by universal joint 15, keeps the vertex of a cone of vacuum cup and supporting rod in alignment by rotating universal joint, so
It is inserted into sandstone or soil afterwards.
Preferably, in order to facilitate other instruments such as level meter on holder, it can test and incline when using level meter
The levelness of rake angle, spirit level installation threaded rod upper end are also associated with steering base 1.
Embodiment of above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although with reference to specific embodiment
The utility model is described in detail, it will be understood by those of ordinary skill in the art that, it can be to the skill of the utility model
Art scheme is modified or replaced equivalently, and without departing from the spirit and scope of technical solutions of the utility model, should all be covered
In the protective scope of the claims of the utility model.
