This invention discloses a shear force distribution demonstration device and measurement method, belonging to the field of structural engineering teaching technology. The device includes a base, a support mechanism, a loading mechanism, a demonstration mechanism, and a measurement mechanism. The support mechanism is a frame structure with sliding rails; the loading mechanism has replaceable supports with switchable constraints; the demonstration mechanism uses replaceable vertical columns with four-jaw chuck sleeves; and the measurement mechanism includes a strain measurement module, an S-shaped tension sensor, and a positioning ruler. This device adopts a fully modular, quick-release design, allowing for rapid switching between series and parallel systems, column constraint forms, and parameters. It simultaneously demonstrates the core knowledge points of inter-story force transmission in series and intra-story force distribution in parallel, verifying the shear force distribution law through measured data. This invention is easy to operate, combining visualization and quantitative measurement, effectively solving the pain points of abstract and difficult-to-understand traditional teaching methods, and significantly improving teaching effectiveness.

This utility model discloses a measuring fixture for strut alignment, belonging to the field of measuring devices for strut misalignment. It solves the problems of traditional tape measure methods, which require two people, involve cumbersome operation steps, accumulate large errors, and are unsafe. This utility model integrates two rulers, using countersunk bolts, washers, nuts, and large-head bolts, onto a "C"-shaped limiter with a "┻" groove and a base with a rectangular groove and through hole. Rotating the nut loosens or tightens the limiter, and rotating the large-head bolt loosens or fixes the rulers. By sliding the limiter and rulers, the rulers can move and be fixed freely in two-dimensional space, assembling a portable, adjustable strut alignment measuring fixture, thus achieving the function of measuring with two rulers at once. This utility model is suitable for measuring strut misalignment and other plate alignment measurements in steel structure manufacturing and construction. It achieves single-person operation, fewer steps, simple operation, convenient reading, and high accuracy.

The field electronic snow pressure measuring device comprises a transparent cylinder wall, an electronic pressure measuring device is arranged at the top end of the transparent cylinder wall, a handle is arranged at the top of the electronic pressure measuring device, and stainless steel ice breaking teeth are arranged at the bottom of the transparent cylinder wall; the other end of each stainless steel icebreaking tooth is a cambered surface, and the radian of each stainless steel icebreaking tooth is the same as the inner diameter of the transparent cylinder wall; two bosses of which the centers are drilled are arranged on the cambered surface; the bosses are connected with the transparent cylinder wall; eight bosses are arranged at the bottom of the transparent cylinder wall, holes are drilled in the two sides of each boss, stainless steel shafts are installed in the holes, and the stainless steel shafts penetrate through the bosses on the stainless steel icebreaking teeth, so that the stainless steel icebreaking teeth can be folded within the range of 0-90 degrees at the bottom of the transparent cylinder wall. The snow scale overcomes the use defects that the snow scale in use at present cannot be observed normally due to the fact that an old-fashioned rod type scale is tedious in operation, inconvenient to read, numerous in parts and easy to damage and lose, and has the advantages of being convenient to carry by experimenters, quicker and more accurate in reading and more convenient to operate.

The invention discloses an endoscope lens eccentricity detection device which comprises a base plate, the top of the base plate is fixedly connected with a supporting column, the top of the supporting column is fixedly connected with a glass plate, the top of the glass plate is provided with a clamping plate fixing device, and the top of the base plate is provided with a shading device. A detection head is arranged at the top of the glass plate, the first matte clamp is movably connected to the outer circumferential face of the first bidirectional screw, the second bidirectional screw is rotatably connected to the top of the glass plate, the first bidirectional screw and the second bidirectional screw are in transmission connection through a belt pulley set, the second matte clamp is movably connected to the outer circumferential face of the second bidirectional screw, and the second matte clamp is movably connected to the outer circumferential face of the second bidirectional screw. According to the invention, the lens placed at the top of the glass plate is clamped and fixed in the process that the first matte clamp and the second matte clamp gather towards the middle, so that the lens is prevented from displacing and falling off in detection, and data is prevented from jumping in the test process.

The utility model discloses a kind of display device for testing sealing effect of sealing section by using air pressure instead of water pressure, it is related to heat supply pipeline sealing test equipment technical field. Including simulation pipeline, outer tube, air inlet, pressure gauge and waterproof sealing structure, outer tube is sleeved in simulation pipeline surface, simulation pipeline and outer tube are transparent material pipeline air inlet and pressure gauge are all installed in outer tube. The utility model is set by simulation pipeline etc., air pressure test does not need a large number of water storage, avoids the equipment pollution and damage caused by water leakage, and air inlet can accurately control pressure value, pressure gauge reading is intuitive, can quickly judge sealing effect, greatly improves test efficiency and safety;On the other hand, the assembly state and sealing process of waterproof sealing piece, protective shell and annular clamping groove can be clearly observed in the transparent material simulation pipeline and outer tube, which is convenient for troubleshooting failure reason.
