The invention provides a portable optical three-dimensional platform, which comprises a two-stage lifting structure, a linear sliding structure 110 and a rotating structure 112. The two-stage lifting structure adopts a linear bearing and a linear guide shaft as a first-stage lifting mechanism, and a lead screw nut as a second-stage lifting mechanism. In use, the second latch 108 of the first housing 100 is toggled to open the top plate 104 of the housing, and the lifting mechanism is held by two hands and pulled up from both sides, thereby securing the first lifting mechanism to a predetermined height via the latch 119. The rotating handwheel 125 is rotated to rotate the screw 122, so as to drive the linear sliding structure 110 installed on the screw nut 123 to move up and down. The linear sliding structure 110 is mounted on the table top reinforcing rib 127, and the rotating structure 112 is driven to move linearly by rotating the first knob 111. And the optical device 109 is mounted on the rotating structure 112 by means of a clamp. The optical device 109 is rotated by the second knob 113. When the operation is finished, the optical device 109 is detached, the bolt 119 is pulled to release the hand, and the buffer 131 arranged above the housing bottom plate 102 can absorb potential energy. The housing top plate 104 is closed and the second catch 108 is snapped on.
The spectral detection device mounted on the three-dimensional platform can be adjusted within a certain space range by adjusting the lifting structure, the linear sliding structure 110 and the rotating structure 112. Referring to fig. 5, a target light path may be constructed at a specific outdoor location by using two or even more three-dimensional platforms.
The invention adopts a two-stage lifting structure, greatly reduces the size of the platform in a non-working state, and can be brought into a vehicle trunk, thereby reducing the difficulty of carrying the platform when the platform goes out on the basis of ensuring the adjustable height.
The first-stage lifting adopts a linear bearing structure to ensure the stability of the lifting platform when the lifting platform is lifted to a preset position, and the second-stage lifting adopts a ball screw structure to ensure the lifting precision of the lifting platform. In addition, through setting up bolt 119 and buffer 131, made things convenient for lift platform to extend and accomodate.
The invention adopts the structures of the caster 135, the universal foot cup 136, the handle 106 and the like, thereby facilitating the outdoor movement of the platform and adapting to uneven bearing surfaces. Further, rubber is wrapped on the caster 135 and the universal foot cup 136, and a certain shock absorption effect is achieved.
The aluminum profile is adopted as the shell support 101, most parts are made of the aluminum alloy, and therefore the parts can be lightened under the condition of meeting the mechanical requirement, the weight of the whole platform is reduced, and the shell support is convenient to carry and move outside.
Although the present invention has been described with reference to a few preferred embodiments, it should be understood that various changes and modifications can be made without departing from the spirit and scope of the invention as defined by the appended claims.
