A quick-assembly table frame comprises: pillars, drive boxes being disposed at tops of the pillars, and table bases being connected to bottoms of the pillars; a rack connected to the drive boxes; and side plates connected to two sides of the rack and configured to install a table board. Mounting blocks are disposed in the drive boxes, mounting grooves are correspondingly formed in an inner side of the rack, control members are disposed in the drive boxes, and the control members control the mounting blocks to rotate to be limited in the mounting grooves, such that the pillars are detachably connected to the rack. The mounting blocks and the control members are disposed in the drive boxes, the control members stretch out of the drive boxes, the mounting grooves are correspondingly formed in the rack, and when the rack and the pillars are assembled, the control members control the mounting blocks to be limited in the mounting grooves, such that the rack and the drive boxes are fixedly connected, the drive boxes and the pillars are fixedly connected, and thus, the pillars and the rack are fixedly connected. A fixing method based on bolted connection is replaced, assembly and disassembly are easy, and labor and time are saved.

Quick-assembly table frame

A device for detecting an analyte in a sample is provided, which comprises: a collecting chamber containing an opening for collecting a liquid sample; a detecting element for detecting an analyte in the liquid sample; and a lid for covering the opening of the collecting chamber. The device further comprises an indicating device thereon to indicate whether or not the lid covers at an appointed position. The operation of the device is very simple.

Device for detecting analyte in sample

A dispersion and loss spectrum auto-correction distributed optical fiber Raman temperature sensor has a dual fiber pulsed laser module with dual Raman wavelength shifts. The laser module is composed of a power supply (), an electronic switch (), a primary laser () and a secondary laser (), a first combiner (), a bidirectional coupler (), a multimode fiber (), an integrated optical fiber wavelength division multiplexer (), a second combiner (), a direct detection system (), a signal collection and processing system () and a display (). The sensor uses two light sources that have two Raman wavelength shifts, wherein the central wavelength of backward anti-Stokes Raman scattering peak of the primary light source coincides with that of the backward Stokes scattering peak center wavelength of the secondary light source, and the time domain reflection signal of the one-way optical fiber Rayleigh scattering is deducted. Based on the optical fiber Raman scattering temperature measurement principle, the dispersion and loss spectrum auto-correction method and the optical time domain reflection principle, the optical fiber dispersion and the loss spectrum can be self-corrected, and the random power loss caused by bending and stretching in installation can also be auto-corrected.
