The invention discloses a communication auxiliary device with a remote control function, which includes a shading plate, a placement groove, an anti-slip pad and a communication cabinet. The internal temperature of the communication cabinet caused by the cabinet is too high to cause damage to the electronic equipment in the communication cabinet. At the same time, in rainy weather, rainwater is prevented from directly pouring on the communication cabinet, thereby slowing down the speed of communication cabinet corrosion, thereby further prolonging the use of the communication cabinet Life, by setting the groove for placing potted plants and other decorations, it plays a role in beautifying the communication cabinet, thereby further reducing people's fear of the communication cabinet, and increasing the potted plants and other decorations by setting anti-skid pads. The friction force between the inner walls of the trough can avoid the random movement of decorations such as potted plants in the placement trough.

An anti-tipping and quick-group catenary operation ladder truck, comprising: a base (5), a ladder body, and a working platform (10), the opposite sides of the ladder body are trapezoidal, and the base (5) is equipped with an anti-ladder truck rollover The locking mechanism is a push-type normally closed locking linkage mechanism, including: a push armrest (1) arranged on the base (5), and a connecting rod is connected to each side of the push armrest (1) The locking device (2), the chuck (231) of the connecting rod locking device (2) and the base (5) are kept engaged with the rail (3) by the action of the tension spring (25), and press down / Release the push handrail (1) so that the chuck (231) of the connecting rod locking device (2) disengages / engages with the rail (3); the base (5) and the working platform (10) are respectively combined with the ladder body , the ladder body is combined and connected by more than one segment, and the combined connection is equipped with a quick connector (6). Once the ladder car stops, it will be automatically locked to prevent rollover. It can be transported in sections and quickly installed and disassembled. Different heights need to be quickly assembled on site.

The invention relates to the technical field of medical apparatus and instruments, and discloses a multifunctional infusion support. The multifunctional infusion support comprises a hook rack, a telescopic main support and a supporting frame, wherein the telescopic main support comprises a first main support column and a second main support column, and the lower part of the second main support column is arranged in the first main support column in a penetrating manner and is in sliding connection with the first main support column; the hook rack comprises a hook column and a hook bearing, thelower end of the hook column is detachably connected with the upper end of the second main support column, a suspension hook is arranged at the upper end of the hook column, the hook bearing is arranged on the hook column, and multiple hooks are arranged on the hook bearing; and the support frame comprises at least three supporting legs which are arranged at uniform intervals, the upper ends of the supporting legs are rotationally connected with the lower end of the first main support column, and universal wheels are arranged at the lower ends of the supporting legs. Therefore, the multifunctional infusion support has the advantages that different height demands can be met, multiple articles can be suspended, the hook rack can be convenient to carry, the movement is convenient and the areaoccupied by storage is small.

The invention discloses a shape memory alloy floating device for superconducting magnetic levitation microforce measurement, and relates to the field of shape memory alloy application. The floating device comprises a sleeve, a sleeve cover, a support rod, a bias spring, a memory alloy spring and a linear bearing, wherein a lug boss is formed at the upper side of the middle part inside the sleeve for installing the linear bearing; the memory alloy spring is welded at the inner bottom end of the sleeve; the support rod is arranged in the memory alloy spring; the support rod can vertically move along the sleeve; the upper section of the support rod sequentially passes through the bias spring, the linear bearing and the sleeve cover from top to bottom, and finally passes through the sleeve cover; a floated object is placed at the upper side; a flange plate at the bottom end of the sleeve is connected with a refrigerating machine and a heat conducting structure; during the temperature reduction, the memory alloy spring is shortened; the support rod downwards moves under the effects of gravity and the bias spring, and the floated object is driven to downwards move; during the temperaturerise, the memory alloy spring is elongated, and the support rod upwards moves. The processing is easy; the cost is low; the operation is simple and convenient; the intelligentization is realized.

The invention discloses a mask-assisted high-speed soluble abrasive particle electro-hydraulic jet manufacturing surface function microstructure device, which includes a motor, a workpiece placement seat, a processing tank, a cylinder, a circulation pump, a nozzle, an angle plate and a cathode plate, and is rotated by a motor Then it drives the screw rod to rotate, so that the first slider moves on the screw rod, which further drives the nozzle to move directly above the workpiece, and uses the cylinder to drive the piston rod to expand and contract, thereby realizing the adjustment of the height of the second horizontal plate, thereby further realizing The nozzle height can be adjusted to meet the different height requirements of the nozzle in different situations, and the practicability of the equipment is improved. The passivation electrolyte in the processing tank enters the nozzle through the liquid guide hose and further passes through the outlet by using the circulation pump. The material port is sprayed out, and the abrasive supply system is further used to make the abrasive enter the nozzle through the material guide tube and follow the passivation electrolyte to be sprayed out through the material outlet, so as to realize the purpose of processing the surface of the workpiece.
