The invention discloses a bus groove capable of being fast dismounted.Through holes used for connecting a flame-retardant separation plate is arranged on each connecting plate; the connecting plates are driven to move through moving one ends, located outside a first groove, of the moving plates; under the effect of a spring, the first connecting plates are located outside the first groove; the through holes in the connecting plates are moved to a position outside the side plate of the bus groove; one end, connected with the bus groove side plate, of the flame-retardant separation plate is provided with a second groove corresponding to corresponding through holes in the two connecting plates; screw threads are formed in the second groove and the through holes; after the connecting plates are pulled out, screw rods with screw threads penetrate through the through holes to be fixedly connected with the second groove; after the connection, the connecting plates slide into the first groove,so that the flame-retardant separation plate is fixed onto the bus groove side plate. The invention has the advantages that under the condition of effectively improving the repair and replacement efficiency, the intensity of the bus groove per se cannot be influenced; the use is more convenient; the long-time use is convenient.

The invention discloses a novel efficient and anti-creeping bus duct. Through holes for connecting a flame retardant partition plate are formed in connecting plates, each through hole is internally provided with a screw thread, the connecting plates are driven to move by moving the ends, outside first grooves, the connecting plates, under the effect of springs, the connecting plates are arranged outside the first grooves, and the through holes in the connecting plates are moved to the outsides of bus duct side plates; second grooves corresponding to the through holes correspondingly in the twoconnecting plates are formed in the end, connected with the bus duct side plates, of the flame retardant partition plate, a rotating plate is arranged on each second groove, the upper end of each rotating plate can rotate inside the corresponding second groove along the straight line of the axis of the corresponding second groove, the lower end of each rotating plate is connected with the upper end of the corresponding connecting plate, a screw thread corresponding to each through hole is arranged at the lower end of the corresponding connecting plate, each connecting plate is rotatably connected into the corresponding through hole through the corresponding screw thread, after the connection is finished, the connecting plates slide into the first grooves, and the flame retardant partitionplate is fixed onto the bus duct side plates. When the device can be quick and convenient to maintain and replace during maintenance and replacement, and the using efficiency is higher.

The invention provides a computer component overturning device. The device comprises a fixed box, an overturning frame, a lifting device and a clamping device, two bent plates are arranged on one sideedge of the fixed box; the overturning frame is arranged between the two bending plates in an overturning manner; the lifting device is arranged on the inner wall of the fixed box; the lifting deviceis used for pushing one end of the overturning frame to be separated from the fixed box; the clamping device comprises rotating pieces fixed to the two sides of the overturning frame, clamping stop pieces arranged on the bending plate, and springs abutting against the side faces of the clamping stop pieces. One end of the clamping stop piece is provided with a stop end, the rotating piece is provided with a step face, and the stop end abuts against the step face to limit the turnover frame to turn over within the range of 90 degrees. According to the computer assembly turnover device, the turnover angle of the turnover frame is limited, and the turnover frame can be stably fixed when rotated into the fixing box.

The invention relates to a combined adjustable cable support. The combined adjustable cable support comprises a fixing part and at least one group of support parts, wherein the fixing part comprises a cross rod, nuts and a deformation alarm; the deformation alarm comprises a deformation sensor, a power supply, a controller, an alarm and a casing; the deformation sensor is mounted in the middle of the cross rod; the power supply and the controller are mounted in the casing; the alarm is mounted outside the casing; the deformation sensor, the power supply and the alarm are electrically connected with the controller; each support part comprises a hanging rod support, a cable support and a sleeve; the cable support comprises a supporting plate and reinforcing ribs; a mounting hole is formed in one end of the supporting plate, and a blocking column is arranged on one surface of the supporting plate; an insertion hole is formed in the side surface of the sleeve; the supporting plate is fixed in the insertion hole through a plug pin; a positioning hole is formed in the sleeve; fixing holes of a mounting positioning pin and a spring are formed in the side surface of the sleeve; the hanging rod support comprises a vertical rod and a base plate with an adjusting hole; external threads are formed at the upper end of the vertical rod, and internal threads are formed at the lower end of the vertical rod. The combined adjustable cable support can effectively solve the problems that the angle adjustment of the cable support is inflexible, and increasing cable supports during the later period is difficult.

The invention discloses a novel bus duct convenient to use. A bus duct body includes a flame-retardant partition plates provided with a plurality of square holes, and conducting wire partition platespenetrating through the square holes and vertically connected to the flame-retardant partition plate. A first placement groove is disposed between two adjacent square holes on the flame-retardant partition plate; a plurality of second placement grooves are disposed on the first placement groove; rotatable pulleys are disposed in the second placement grooves; the axis of each of the pulleys is parallel to a plane of the flame-retardant partition plate; the diameter of each of the pulleys is the same as the distance between the adjacent two square holes; and when the conducting wire partition plates are inserted into the square holes, the conducting wire partition plates are in contact with side surfaces of the pulleys, and the pulleys are driven by the conducting wire partition plates to rotate. When the device is used, the novel bus duct is more convenient to quickly and conveniently insert the conducting wire partition plates into the square holes and can be effectively fixed after being stuck in, without affecting usage.
