74results about How to "Power transmission is simple" patented technology

An articulated robot capable of reducing dead space while maintaining a wide operating area and simplifying a power transmission system necessary for moving each joint. A plurality of joint arms A1 to A7 are connected via first rotating shafts 15, 15A, and 15B as horizontal rotating shafts and via second rotating shafts 32, 32A, and 32B as inclined rotating shafts alternately. A motor M for driving the rotating shaft and a speed-reducing mechanism are provided for each rotating shaft.

The invention relates to a clamping mechanism for a precision injection molding machine. The clamping mechanism comprises a structure frame composed of a fixed die plate, a movable die plate, a rear die plate and a guide column, a movable die plate fast moving mechanism and a clamping cylinder structure; the section of the guide column on the structure frame is rectangular, four corner parts of the movable die plate are provided with rollers on the upper column surface, the lower column surface and the inner side of the guide column; the movable die plate fast moving mechanism is composed of a motor reduction gear, a pair of engaged gears and rack and a guide wheel; the clamping cylinder structure is composed of four cylinders, a clamping support plate and a transmission mechanism, and the rear die plate has a through hole through which a cylinder piston rod is capable of passing. The clamping mechanism provided by the invention has the advantages that the friction between the movable die plate and the guide column is changed as the rolling friction from the sliding friction, the fit clearance is adjustable, the movement precision is improved, the movement resistance is decreased, and the energy consumption is reduced; through the rotation of the clamping support plate, the length of the guide column required for die closing is greatly shortened through the support or discharging provided for the cylinder piston rod, the whole machine body is reduced, and the control is simplified.

A horizontal open inducting garbage bin includes a bin body, a bin head, an inducting window, a garbage inlet disposed on the bin head, a bin cover disposed on the garbage inlet, an upright shaft and a drive arrangement for making the upright shaft rotate. The upright shaft is connected to the drive arrangement, and the bin cover is connected to the upright shaft, the connecting point is not at the center of the bin cover. The advantages of the invention are: the rotating shaft of the bin cover is the upright shaft on the bin head, so when the bin cover rotates about the upright shaft, the bin cover opens horizontally about the upright shaft, the drive force is small, low energy is needed, and the user's hand cannot be touched by the bin cover.

The invention relates to a corner stone connecting component, and relates to the technical field of stone curtain walls. The technical problem that in the prior art, corner stone is not firm in fixing is solved. The corner stone connecting component comprises a combining connecting piece used for connecting large-face stone with corner stone. The large-face stone and the corner stone are connected through the combining connecting piece, stress and force transmission of the corner stone connecting component are clear, stress and force transmission are achieved through a fixing piece, calculation is simple, and control is convenient. A traditional technology that stress and force transmission are conducted through bonding performance of dry hanging stone glue is eliminated, the situation that due to the glue quality, different using environments and human factors of operators, the quality is influenced is avoided, and the corner stone is fixed stably and reliably.

The invention discloses a hollow shear wall structure for a cross diagonal reinforcing bar. The hollow shear wall structure for the cross diagonal reinforcing bar comprises a shear wall body, wherein the inside of the shear wall body is provided with the horizontal-direction reinforcing bars of a wall body, the vertical-direction reinforcing bars of the wall body and wall body tie bars, wherein two groups of cross diagonal reinforcing bar cages are respectively arranged along the plane diagonal direction of the shear wall body; the cross diagonal reinforcing bar cages are bond and connected with the horizontal-direction reinforcing bars of the wall body and the vertical-direction reinforcing bars of the wall body; each group of cross diagonal reinforcing bar cage at least comprises four cross diagonal reinforcing bars and cross diagonal stirrups processed into a closed rectangle; the cross diagonal reinforcing bars and the cross diagonal stirrups are bond to form a rectangular strip-shaped cross diagonal reinforcing bar cage; and the inside of each space surrounded by the horizontal-direction reinforcing bars of a wall body, the vertical-direction reinforcing bars of the wall body, the wall body tie bars and the cross diagonal reinforcing bar cages is respectively embedded with a light internal die of a blocky foam plastic. The construction method for the hollow shear wall structure for the cross diagonal reinforcing bar comprises the following steps of: erecting a shear wall template; binding wall body reinforcing bar meshes; laying and binding the cross diagonal reinforcing bar cages; embedding the light internal die of the blocky foam plastic; and pouring and curing the shear wall concrete. According to the invention, materials are saved, the structural self weight is lightened, and the resistance to shock is good.
