The invention provides a cable on-off testing system, which includes a housing, an ear plate, a wire placement frame structure, a support rod, a moving wheel, a tool placement frame structure, a positioning hole, a workbench, a work protection frame structure, a multimeter, test pens, and wires. The end fixing frame structure, the baffle plate, the wire support frame and the arc groove, the ear plates are respectively welded on the left and right sides of the upper part of the front end of the shell; the wire placement frame structure is installed on the inner lower part of the ear plate; The supporting rods are respectively arranged on the left and right sides of the wire placement frame structure. The beneficial effects of the present invention are: through the setting of the mounting plate, the support column and the U-shaped frame, the redundant wires are placed on the upper part of the mounting plate or wound on the inner side of the U-shaped frame, which is conducive to conveniently winding the redundant part of the wires on the U-shaped frame. The inner side of the type frame is convenient for the staff to detect the longer wires and increase the use function of the equipment.

The invention discloses a lightning arrester with the leak current measuring function. The lightning arrester aims to solve the technical problems that leak current detection in an existing lightning arrester is interfered by strong electromagnetism, signal extraction difficulty is large, and electrification monitoring can not be achieved easily. The lightning arrester comprises an umbrella cover with the sealed exterior, and a core set arranged in the umbrella cover. A first aluminum electrode is arranged on the upper portion of the core set, and a leak current measuring sensor is arranged on the lower portion of the core set; the leak current measuring sensor comprises a second aluminum electrode, a third aluminum electrode and a resistance disc, a detection positive electrode P+ led out to the exterior of the umbrella cover is arranged in the second aluminum electrode, and a detection negative electrode P- is led out from the bottom end of the third aluminum electrode; the resistance disc is formed by connecting a sampling resistor R and a protecting valve plate Z6 in parallel. The lightning arrester and the leak current measuring sensor are integrally arranged, the electrodes are led out and connected to a measuring instrument, and on the premise of not influencing the lightning protection effect of a lightning arrester body, electrification monitoring of leak currents of the lightning arrester is achieved.

A machine tool guide rail protective cover with its own air blowing function, including: a cover body, a drive linkage mechanism, an air source pipe, an air inlet duct, an air outlet hole, an exhaust duct, and a rubber sealing strip; The air is blown in the channel, and the pressurized gas is discharged into the groove through the air outlet hole on the inlet channel, blowing up the cutting waste particles accumulated in the groove, and then blown out by the gas from the exhaust channel, realizing the automatic removal of adjacent covers The good technical effect of the cutting waste accumulated at the joints of the body prevents the accumulation of waste from affecting the protective effect of the protective cover, reduces the labor intensity of the staff, and improves the cleaning efficiency and cleaning quality.

The invention provides a short distance material transferring device for subway construction. The short distance material transferring device for subway construction comprises a motor forward and backward rotation remote control switch and a remote controller; a material storage groove is formed in the top of a vehicle body; crawler wheels at four corners are rotationally connected to the bottom of the vehicle body through axles; eight warning lamps are arranged; the eight warning lamps are correspondingly mounted on the end surfaces of the left and right sides of the vehicle body; the warninglamps are connected with an external power supply line through power supply wires; the bottom of a supporting frame is mounted on the end surface of the top of the vehicle body through a bolt; the top of the supporting frame is connected with the bottom of a top cover; the short distance material transferring device for subway construction is beneficial for increasing the contact area between thebottom of the device and the ground so that the device is more stable in operation and the building material transporting effect is improved; and moreover, under cooperation of a fixing strip and a hook & loop, building materials transferred by the device can be bound and fixed so that the materials are more firmly placed in the device; and therefore, the building materials are prevented from falling to the left and right ends of the device in the transferring process to affect the material transferring effect.

The invention discloses a garment with a thermal layer. The garment comprises a collar, a garment body, sleeves and pressurizing balls. A zipper is arranged at a middle position of the front side of the garment body. Pockets are arranged on the parts, on the two sides of the zipper, of the garment body. The two sides of the top end of the garment body are both provided with the sleeves. A fluff layer is arranged on the inner side of the garment body. A first elastic cloth is arranged on the inner side of the part, at the collar position, of the garment body. According to the garment disclosedby the invention, first magnets are arranged on the sides, close to the garment body, of the sleeves, and third magnets and second magnets, which have the same magnetism as the first magnets and are decreased in magnetic force, are arranged at the positions, at the same height as the first magnets, in the pressurizing balls respectively; in the process of wearing the garment, arms of a human bodyswing to force the third magnets and the second magnets inside the pressurizing balls to generate deformation of different distances at the time that the first magnets approach the third magnets, thereby squeezing the pressurizing balls; through reciprocating motion, a rubber ring and a protective airbag are inflated, and therefore the protection and warm keeping effects of the garment are improved.
