This utility model relates to the field of watch accessory technology, specifically a novel anti-lost wristwatch, comprising a watch body and two wristbands. The ends of the two wristbands are connected to a locking assembly, which includes a first lock and a second lock. An insert is fixedly installed on the inner surface of the first lock, and a pre-drilled groove is formed on the inner surface of the second lock. A roller, a limiting ring, and a sleeve are installed inside the pre-drilled groove. Several reinforcing members are interlaced inside the wristbands. Elastic bands are connected to the tops of both wristbands, and a metal braided strap is fitted over the elastic bands. This novel anti-lost wristwatch connects the first and second locks by inserting the insert into the sleeve. Rotating the roller causes the limiting ring to rotate, causing the sleeve to rotate and misalign with the groove, preventing the insert from being pulled out. This achieves a combination lock connection between the first and second locks, preventing patients from removing the watch themselves and reducing the difficulty for caregivers to remove the watch.

The present application belongs to the technical field of epoxy cast dry-type power transformers, and in particular, is a high-voltage coil airway placement structure, including a high-voltage coil and an airway, wherein the front surface of the high-voltage coil is provided with a through airway, an airway square tube is installed in the airway, the airway square tube and the high-voltage coil are fixedly connected, and an I-beam strut is installed on one side of the airway close to the airway square tube; after the wire is wound around the inside of the airway, internal insulation is placed, and then an airway square tube is placed in the airway, and then an I-beam strut is placed, because the thickness of the I-beam strut is matched with that of the airway, the I-beam strut can be firmly fixed in the airway, further stabilizing the connection between the I-beam strut and the high-voltage coil and facilitating the plugging and unplugging of the airway square tube, and continuing to wind in the third and fourth sections, an airway square tube is provided between every two I-beam struts to avoid cutting and welding of the wire, which not only reduces the coil winding time but also improves product quality.

The utility model discloses a kind of oil cylinder support mounting structure of coal mill hydraulic system, including nut block prepositioned in the bottom plate of coal mill and double-end bolt connected with nut block and threaded in oil cylinder support, fixed sleeve is sleeved in the outside of double-end bolt, the fixed sleeve one end is abutted with the surface of oil cylinder support, and the other end is locked and fixed by the double-nut structure of the end of double-end bolt and is connected by thread, the installation and fixation of oil cylinder support are completed by double-end bolt and fixed sleeve;By double-nut structure and fixed sleeve cooperation, bolt shearing problem caused by effectively prevent connection loosening, improve the service life of double-end bolt, ensure the stable operation of hydraulic oil cylinder.

A winding machine clamping mechanism belongs to the field of winding processing technology. By installing a one-way clamping plate assembly inside the mounting tube, the one-way clamping plate assembly prevents the enameled wire from retracting after being cut by the wire cutting clamping mechanism, reducing manual handling of the enameled wire and increasing winding efficiency. By installing a power component inside the mounting tube, the extension of the enameled wire can be controlled. When the enameled wire retracts, controlling the rotation of the first servo micro motor allows the enameled wire to be delivered, avoiding manual handling and reducing winding efficiency. By installing the wire cutting clamping assembly, the wire cutting cylinder can be directly integrated into the mounting tube, thus avoiding the need to guide the enameled wire to the frame assembly for clamping before cutting, effectively reducing waste of enameled wire and preventing increased costs.

The invention discloses a composite aluminum pipe double-end spinning machine and a using method thereof.The composite aluminum pipe double-end spinning machine comprises a working table, a rotating clamp is detachably installed on the working table, servo driving mechanisms are symmetrically arranged on the two sides of the rotating clamp, and each servo driving mechanism comprises three sets of servo driving motors and three sets of stepping driving motors; the two sets of symmetrically-arranged spinning wheels are driven through the lead screw sliding table module, and the two ends of the small-pipe-diameter blank pipe are extruded and sealed. The using method comprises the steps of resetting operation, setting operation parameters, and sequentially completing pushing feeding, clamping and fixing, spinning sealing, moving wheel withdrawing and loosening discharging operation. The three sets of servo motors and the stepping motors drive the spinning wheels to extrude and shape the two ends of the blank pipe according to the set operation parameters, the sealing production process of the small-pipe-diameter composite aluminum pipe is simplified, and the production efficiency and the sealing quality are effectively improved.

The present invention discloses a device and method for picking fresh yellow bud tea leaves, comprising an electric housing, a connecting rod, a frame, a storage curved plate and a picking component, wherein one end of the connecting rod is provided at the bottom of the electric housing, the other end of the connecting rod is mounted on the mounting frame, the storage curved plate is fixedly mounted on the mounting frame, and the picking component is mounted in the frame. When the machine shears the yellow bud tea leaves, the present invention ensures the overall integrity of the yellow bud tea leaves, and prevents some complete tea leaves from being cut by the machine, thereby reducing the quality of the yellow bud tea leaves and reducing the yield of the yellow bud tea leaves.

The invention discloses a novel sheave for a mine hoist, comprising a wheel hub, a wheel rim, a wheel spoke and a copper shoe. The wheel hub comprises two groups of mutually symmetrical semicircular wheel hub assemblies, the two groups of semicircular wheel hub assemblies are assembled to form the wheel hub, each group of semicircular wheel hub assemblies comprises two semicircular plates of the same shape and size, a gap is left between the two semicircular plates, at least two connecting blocks are arranged in the gap, the connecting blocks are respectively welded to the two semicircular plates, semicircular reinforcing plates are welded on the outer sides of the two semicircular plates, the outer diameter of the reinforcing plates is smaller than the outer diameter of the semicircular plates, the design structure of the invention is simple, the wheel hub of the traditional casting structure is designed as a welded structure, the overall weight of the wheel hub and the sheave of the same size is effectively reduced, and the key connection method between the copper shoe and the wheel hub is used to replace the traditional bolt connection method, so as to avoid frequent maintenance of the sheave, which is beneficial to extending the service life of the sheave.
