This invention discloses a semiconductor quartz component polishing device, relating to the field of quartz component polishing technology. The device includes a main body, inside which a polishing assembly and a rotating assembly coaxially arranged with the polishing assembly are installed. A mounting arm is mounted on the rotating end of the rotating assembly, and a ball head seat is mounted at the bottom of the mounting arm. A positioning assembly capable of vertical rotation is installed inside the ball head seat. Through the arrangement of the polishing assembly and the positioning assembly, the quartz rod is positioned, allowing the polishing assembly to first polish the end of the quartz rod. Then, combined with the cooperation of the rotating assembly and the electric push rod, the entire circumference of the quartz rod's end face can be uniformly and continuously contacted with the polishing assembly. This eliminates the need for manual polishing of the quartz rod by hand, efficiently chamfering the end of the quartz rod, eliminating quality fluctuations caused by inconsistent polishing force and path during manual polishing, effectively removing micro-cracks, scratches, and unevenness left from cutting, and reducing potential stress concentration points.

The present invention relates to the technical field of UV board detection, and specifically to a comprehensive detection device and method for the appearance quality of a surface finishing layer of a UV board, comprising: a frame structure, on which a clamping assembly for clamping the UV board is rotatably mounted; a coaxial wheel set, fixedly connected to the rotating shaft of the clamping assembly; a locking assembly, arranged on the frame structure, the locking assembly cooperates with the coaxial wheel set to axially lock the clamping assembly, and a second cam is also arranged on the locking assembly; a power assembly, installed on the frame structure and adapted to the second cam, the power assembly can drive the locking assembly to move and the coaxial wheel set to rotate in turn; an abutment rod, arranged on the frame structure, the abutment rod cooperates with a third cam arranged on the power assembly, and can separate the second cam from the power assembly after the coaxial wheel set rotates a predetermined angle, thereby realizing double-sided detection and reducing the difficulty of operation.

This utility model belongs to the technical field of rebar processing equipment, specifically relating to a straightening and traction fixing device for coiled rebar. The lower end of a support column is mounted on one end of the base along its length via a rotating mechanism. A support beam is provided in the upper middle part of the support column, extending upwards and inclined towards the other end of the base. The rotating mechanism includes a rotating seat and a rotating body, with the rotating body rotatably connected within the rotating seat. The upper end of the rotating body is fixed to the support column. Limiting grooves are provided on both sides of the rotating seat corresponding to the width of the base, and limiting strips extending into the limiting grooves are provided on both sides of the rotating body. With this rotating mechanism featuring a limiting structure, the support column can rotate horizontally relative to the rotating seat via the rotating body. Combined with the angle limitation of the fan-shaped limiting grooves, this not only adaptively compensates for the angular deviation of the coiled rebar unwinding, eliminating torsional stress in the rebar, but also prevents excessive deflection of the support column, avoiding feeding jams and equipment shaking, significantly improving the straightening accuracy of the rebar.

The utility model discloses a flange type low-temperature valve supporting structure which comprises a valve body supporting assembly and a heat insulation assembly which are connected through a connecting assembly to achieve a supporting function. The valve body supporting assembly comprises a hoop and a supporting frame, the heat insulation assembly comprises a hard heat insulation block and a bottom plate, and the hard heat insulation block can bear the weight of a valve, block heat conduction between the valve body supporting structure and an external supporting body and block a cold bridge. According to the supporting structure, the phenomenon that the deflection of the valve is too large due to the fact that the valve body is too heavy is avoided, cold energy of a medium is prevented from being transmitted to an external supporting body through the supporting piece, and a cold bridge is effectively avoided; the utility model has the characteristics of reasonable structural design, stable and reliable performance, wide application scene and the like.

This utility model belongs to the field of display screen technology, specifically a multi-angle adjustable LED display screen, including a support base. A connecting rod is provided at the top of the support base, and a support rod is provided at the top of the connecting rod. The inner wall of the support rod and the surface of the connecting rod are rotatably connected via a damping shaft. A mounting block is provided at one end of the support rod, and the mounting block is fixedly connected to the LED display screen body by bolts. By setting an adjustment mechanism, the support base is placed on the contact surface. If the contact surface is tilted, rotating the second gear drives the first gear to rotate, thereby allowing the concealed box to rotate within the rotating shell. The concealed box and the rotating shell remain connected during rotation, thus changing the placement angle of the LED display screen body, keeping the LED display screen body in a horizontal position and preventing tilting of the LED display screen body.

The present invention relates to the field of heartbeat monitoring technology, in particular to a collar for heartbeat health monitoring of elderly cats, comprising a collar portion that is surrounded in a circle and a control chamber arranged on the collar portion, wherein a motion detection sensor and a heart rate monitoring sensor are arranged in the control chamber, and the heartbeat of the elderly cat is monitored by the heart rate monitoring sensor. A guide trapezoidal groove is provided on the inner surface of the collar portion, and two groups of mutually symmetrical triangular chucks are arranged in the guide trapezoidal groove. The present invention can monitor the heartbeat of the elderly cat, and can automatically control the triangular chucks to extend and clamp the cat's hair when the cat is in an active state, so as to limit and stabilize the collar, avoid excessive deflection and activity of the collar, and improve the stability of the collar for heartbeat monitoring when the cat is in an active state.
