Description
[technical field]
The utility model relates to the levelling staff technical field, the universal telescopic strut of specifically a kind of levelling staff.
[background technology]
Measurement of the level has another name called " geometric leveling ", is the method for measuring the point-to-point transmission discrepancy in elevation on the ground with spirit-leveling instrument and levelling pole.Settle spirit-leveling instrument at the ground point-to-point transmission, observation is erected at the levelling staff on 2, presses the discrepancy in elevation of reading reckoning point-to-point transmission on the chi.
Existing levelling pole all is to be held to guarantee the plumbness of levelling staff blade with hand steered by survey crew, support can cause survey crew fatigue for a long time, add the influence of the objective weather environment of field operation, be difficult to be maintained the stable of blade, cause measurement error to occur.
CN201803726 discloses a kind of levelling staff telescopic strut, adopt horizontal and longitudinal extension bar structure, actual when carrying out measuring operation, want earlier levelling staff to be stood on measuring point, unclamp expansion link then, transverse bar is towards the lower left, and longitudinal rod is towards the back lower place, stretch to be pulled to about 45 ° angle respectively and land, again locking.This moment two expansion links the vertical length length of landing of being longer than levelling staff, owing to will control scale on the other hand, the another hand can only be controlled expansion link longitudinally, so horizontal expansion link must unclamp, shrinks, tighten when measurement finishes.So point of every measurement, expansion link all must be done and unclamp → stretch twice action of drawing → locking and unclamping → shrinking → locking, and is very inconvenient.。
[summary of the invention]
The purpose of this utility model is at above-mentioned deficiency, designs a kind of coupling arrangement perfect in shape and function, levelling staff expansion link easy to use.
To achieve these goals, the utility model designs the universal telescopic strut of a kind of levelling staff, comprise levelling staff, the main body (1) that it is characterized in that web member is a rectangular structure, the cross section is a square, connector main body one end is provided with circular projection (2) along the axis, the top of projection is the male buckle contiguous block (3) of the rectangular parallelepiped of the external thread and the flat pattern that is threaded, the center upper portion of male buckle contiguous block is provided with screw (4), male buckle contiguous block side is provided with screw (5), male buckle contiguous block injects the female buckle (15) at levelling staff (14) middle part, screw is fixed then, the connector main body other end centre position parallel with axle is provided with rectangle slotted eye (6), insert the first telescopic strut support (7) one ends in the described rectangle slotted eye and use the internal thread screw to connect, connector main body upper left-hand centre position is provided with one and becomes vertical tenon (8) with axis, the tenon of connector main body be inserted into the secondary accessory universal joint of web member (9) one end levels to slotted eye (10) in fix with pin (11), the universal joint other end be provided with the upper end level to vertical rectangle slotted eye (12), described rectangle slotted eye inserts the second telescopic strut support (13) one ends and connects with the internal thread screw.
Described universal joint one end level to slotted eye insert to connect the tenon of connector main body, 90 ° of rotations about universal joint can be done.
Described connector main body and universal joint connect together parallel and two support bars between can do 90 ° of rotations up and down.
The described first support bar support inserts can do 90 ° of rotations up and down in the rectangle slotted eye that connects connector main body.
The described second support bar support inserts can do 90 ° of rotations up and down in the rectangle slotted eye that is connected to universal joint.
The utility model compared with prior art, its advantage is: of the present utility modelly do comprehensive rotation, convenient actual the use need all do not done at each measuring point and be unclamped → stretch the action of drawing → locking and unclamping → shrinking → locking.
