4results about How to "Guaranteed rotation angle" patented technology

The utility model discloses an automatic clamping corner device for a pipe bending machine, which comprises a fixing plate, a die-in fixing seat arranged on the fixing plate through a left-right sliding device, a corner seat arranged on the die-in fixing seat through an up-down sliding device, a rotating die arranged on the corner seat through a rotating device, and a clamping device arranged on the rotating die. The rotating die can rotate relative to the center line of the rotating die through the rotating device; a clamping groove is inwards formed in the circumference of the rotary die, and the position of the clamping groove ensures that the center line of a pipe is overlapped with the center line of the rotary die when the pipe is placed at the bottom of the clamping groove; and a pipe clamping die assembly for clamping the pipe to abut against the bottom of the clamping groove is arranged on the corner seat. The device is arranged near a pipe bending wheel module on the pipe bending machine, assists the pipe bending wheel module in pipe bending, is simple and compact in structure and small in occupied space, can accurately guarantee the rotating angle of a pipe, and greatly improves the percent of pass of products.

This application relates to the field of photovoltaic (PV) bracket design, and provides an adjustable solar PV bracket, including a main beam, at least one support column, and at least one semi-circular panel frame. The support column is fixed to a foundation carrier, and the main beam is rotatably mounted on the top of the support column. The semi-circular panel frame is fixed to the main beam, and an adjustment mechanism is provided between the semi-circular panel frame and the support column. The support column is equipped with a locking mechanism for positioning the rotation angle of the semi-circular panel frame. The locking mechanism includes a rotating rod and a sliding rod. The rotating rod is rotatably connected to the support column, and the rotation of the rotating rod can drive the sliding rod to move axially. In addition, a housing component is fixed to the side of the support column for covering the rotating rod and the first panel frame. Based on this, the accidental change of the installation angle of the PV bracket can be reduced, ensuring that the PV panel maintains good power generation efficiency.

The utility model discloses an exhaust hood with a wind direction adjusting function, which relates to the technical field of exhaust, and comprises a fan, an exhaust port of the fan is provided with an exhaust compression section, and one end of the exhaust compression section far away from the fan is provided with a wind direction adjusting section; a wind direction guiding mechanism is arranged in the middle of the wind direction adjusting section, an air outlet is formed in the end, away from the exhaust compression section, of the wind direction adjusting section, and a wind direction adjusting mechanism is arranged at the air outlet; connecting plates are arranged at the two ends of the exhaust compression section, bolts are arranged in the connecting plates, and one ends of the bolts are connected with the draught fan. The air exhausting device can achieve air exhausting of the fan, can effectively improve the cooling effect on the roller by increasing the air speed, is suitable for the metal cooling process after heat treatment, adjusts the air direction according to actual requirements, ensures uniform cooling, and avoids the problem of non-uniform cooling of metal after heat treatment.

The invention provides a windowing and drilling integrated steering device which is characterized in that a drilling channel and a windowing channel which are independent from each other are arranged in an integrated mechanism, and a drilling hole communicated with the drilling channel and a windowing hole communicated with the windowing channel are formed in the circumferential direction of the integrated mechanism; the steering mechanism is provided with a lifting and placing column and a steering assembly, the lifting and placing column is movably arranged in the steering assembly in a penetrating mode, the steering track is annularly arranged in the circumferential direction of the lifting and placing column, the lifting and placing column is outwards provided with a reversing key in a protruding mode in the radial direction of the lifting and placing column, and the reversing key is movably embedded in the steering track. The steering track is provided with a steering wall which inclines towards the axial direction of the lifting and placing column in the circumferential direction of the lifting and placing column, the lifting and placing column can rotate or stop being fixed through abutting connection of the steering key and the steering wall, and the lifting and placing column is connected to the top of the integrated mechanism and used for driving the integrated mechanism to synchronously move or rotate; the problem of integrated construction operation of underground windowing operation and steering drilling operation is solved, the construction technology is simplified, and casing windowing and jet drilling are achieved more efficiently.
