Abstract
The utility model relates to the technical field of geographic surveying and mapping tools, in particular to a protection device for a surveying and mapping instrument, which comprises an elastic connecting mechanism and a protection cover, wherein: elastic connection mechanism includes fixed plate, well cavity post, spring and dead lever, and fixed plate fixed connection is to the upper end of surveying instrument support frame, and on well cavity post fixed connection to fixed plate, spring fixed connection to well cavity post in, the one end slidable of dead lever is connected to well cavity post on, the other end fixed connection of dead lever is to the protecting shield on. According to the utility model, after the protective cover is contacted with the ground and collides, the protective cover drives the fixing rod to slide in the hollow column and extrude the spring, and the elastic force generated after the spring is pressed hinders the movement of the fixing rod, so that the protective cover is prevented from being contacted with the surveying instrument, the surveying instrument is effectively prevented from colliding with the ground after being fallen down, and the surveying instrument is not easy to damage after falling down.
Description
Technical Field
The utility model relates to the technical field of geographic surveying and mapping tools, in particular to a protection device for a surveying and mapping instrument.
Background
Surveying instrument is the instrument that often uses in the survey and drawing operation, be one kind and be used for various orientations, the range finding, the angle of measurement, the height finding, the instrument of aspects such as mapping and photogrammetry, when measuring through surveying instrument, often can touch rainy day, rainwater falls on measuring the lens when surveying instrument is measured, be not convenient for measure through surveying instrument, shelter from through the umbrella usually, one hand need tightly hold the umbrella when sheltering from through the umbrella, the one-hand surveying instrument can't be operated effectively, simultaneously surveying instrument is blown down by the wind when the wind blows, the surveying instrument bumps with ground after falling to the ground, lead to the surveying instrument easily to take place to damage.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defect that the surveying instrument is easy to damage due to the collision between the surveying instrument and the ground after falling to the ground in the prior art, and provides a protection device for the surveying instrument.
In order to achieve the purpose, the utility model adopts the following technical scheme:
designing a protection device for a surveying instrument, comprising an elastic connection mechanism and a protective cover, wherein:
elastic connection mechanism includes fixed plate, cavity post, spring and dead lever, fixed plate fixed connection to the upper end of surveying instrument support frame, cavity post fixed connection to on the fixed plate, spring fixed connection to in the cavity post, the one end slidable of dead lever is connected to on the cavity post, the other end fixed connection of dead lever to on the guard shield.
Preferably, both sides of the protective cover are connected with a plurality of elastic bulges.
Preferably, the protective cover is rotatably connected with a transparent plate, the transparent plate is fixedly connected with a clamping block, the protective cover is fixedly connected with a connecting seat, and the connecting seat is matched with the clamping block.
Preferably, the transparent plate is a glass plate.
Preferably, the protective cover is fixedly connected with a top edge plate for protecting the surveying and mapping instrument.
The protection device for the surveying instrument provided by the utility model has the beneficial effects that:
after colliding with ground contact through the safety cover, the safety cover drives the dead lever and slides and extrude the spring in the cavity post, and the elasticity that the spring produced after being pressed hinders the removal of dead lever to hinder safety cover and surveying instrument contact, effectually avoid surveying instrument to collide with ground after falling down, make surveying instrument difficult emergence after falling down damage.
Drawings
Fig. 1 is a schematic structural diagram of a protection device for a surveying instrument according to the present invention;
FIG. 2 is a schematic cross-sectional view of a protection device for a surveying instrument according to the present invention;
fig. 3 is a schematic view of a connection structure between a protective cover and a top edge plate in the protective device for a surveying instrument according to the present invention.
In the figure: surveying instrument support frame 1, elastic connection mechanism 2, safety cover 3, elastic bulge 4, transparent plate 5, fixture block 6, connecting seat 7, top edge plate 8, fixed plate 21, cavity post 22, spring 23, dead lever 24.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Example 1
With reference to fig. 1-3, a protection device for a surveying instrument comprises an elastic connection 2 and a protective cover 3, wherein:
The working process is as follows: after safety cover 3 collided with ground contact, safety cover 3 drove dead lever 24 and slides and extrude spring 23 in cavity post 22, and the elasticity that spring 23 produced after being pressed hinders dead lever 24's removal to hinder safety cover 3 and surveying instrument contact, effectually avoid surveying instrument to collide with ground after falling down, and safety cover 3 lies in the outside of surveying instrument simultaneously, can shelter from rainwater and dust.
Example 2
Referring to fig. 1-3, as another preferred embodiment of the present invention, on the basis of embodiment 1, two sides of a protection cover 3 are both connected with a plurality of elastic protrusions 4, the elastic protrusions 4 are used for reducing the collision strength between the protection cover 3 and the ground, a transparent plate 5 is rotatably connected to the protection cover 3, the transparent plate 5 prevents rainwater from falling onto a detection head of a surveying instrument, a fixture block 6 is fixedly connected to the transparent plate 5, a connection seat 7 is fixedly connected to the protection cover 3, the connection seat 7 is matched with the fixture block 6, the fixture block 6 is clamped on the connection seat 7 to fix the transparent plate 5, so that the rainwater cannot fall onto the detection lens of the surveying instrument, the transparent plate 5 is a glass plate, and a top edge plate 8 for protecting the surveying instrument is fixedly connected to the protection cover 3, so that the rainwater falling from the protection cover 3 obliquely falls and cannot fall onto the transparent plate 5.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
