The utility model discloses an infrared imaging optical lens grinding clamp in the technical field of optical lens processing, which comprises a grinding equipment base, a side frame is mounted on one side of the top of the grinding equipment base, and the infrared imaging optical lens grinding clamp is reasonable in structure. The infrared imaging optical lens needing to be ground is placed between the upper clamp and the lower clamp according to the fact that the clamps are lower than the vacuum suction cups on the vacuum tube, the two sets of clamps are driven and controlled by the motor A to be in butt joint with each other, and the infrared imaging optical lens can be clamped. And after the infrared imaging optical lens is clamped, the motor A drives and controls the two sets of clamps to be in butt joint again till the inner vacuum suction cups make contact with the surface of the infrared imaging optical lens and adsorb the surface of the infrared imaging optical lens in a vacuum mode, and then the infrared imaging optical lens can be clamped and fixed.

This utility model relates to the field of zipper technology, providing a wear-resistant and anti-slip zipper structure, including a fabric strip. One end of the fabric strip has a top stop, and the other end has a block. A limiting structure is provided on the inner side of the block. A zipper tooth is installed on the fabric strip, and a pin is installed at one end of each tooth. A zipper head is installed on the tooth. Protective structures are provided on the surfaces of both the zipper head and the zipper tooth. The zipper head consists of a locking head, a retaining ring, and a pull ring. The retaining ring is located on the locking head, and the pull ring is installed on the locking head. A detachable structure is provided between the retaining ring and the locking head. This utility model, through its detachable structure, allows for disassembly and replacement. By rotating the fixing rod, the screw retracts from the fixing rod, releasing the fixing ring and allowing the pull ring to be removed, thus improving replacement efficiency. Simultaneously, the retaining ring can also be replaced.

This invention relates to a tooling clamp, and more particularly to a friction stir welding tooling clamp. It provides a friction stir welding tooling clamp that can flexibly adjust its position according to the size of the workpiece, enabling rapid loading and unloading of the workpiece, and possessing high stability and accuracy. The friction stir welding tooling clamp includes an I-shaped support plate, sliders, and clamping rods; two sliders are symmetrically mounted on the I-shaped support plate, and clamping rods for clamping the workpiece are welded to the outer surfaces of both sliders. Through the interaction of the sliders, clamping rods, and chucks, the positioning angle and position can be flexibly adjusted according to the size of the workpiece, thereby achieving fixed clamping of workpieces of different sizes. The fastening and clamping devices enable rapid clamping and unloading of the workpiece, and also greatly improve the stability and accuracy of workpiece clamping.

The utility model discloses a cable wire spool with an identification function, which relates to the technical field of cable wire spools, comprises a rotary drum, limiting plates are arranged at two ends of the rotary drum, and is characterized in that a fixed screen frame is arranged on one side of each limiting plate, and a plurality of fixing grooves distributed at equal intervals are formed in the outer wall of each fixed screen frame; a limiting insertion column is inserted into the inner wall of the fixing groove, the limiting insertion column is connected with a label plate, contraction grooves are formed in the two sides of the limiting insertion column, extrusion blocks are connected to the inner walls of the contraction grooves through extrusion springs, and anti-skid convex particles are arranged on the outer walls, away from the extrusion springs, of the extrusion blocks. Friction force between the limiting inserting columns and the fixing grooves is increased, a good fixing effect is achieved, and the situation that the label plate falls off is avoided.

This utility model relates to the field of privacy film technology, and in particular to a substrate-free privacy film, comprising a privacy film body, an optical adhesive layer on the back end of the privacy film body, a release film layer on the end of the optical adhesive layer away from the privacy film body, a waterproof main strip on the lower surface of the privacy film body, a drainage side guide strip on the waterproof main strip, a pull tab on the upper end of the release film layer, and anti-detachment strips at both ends of the release film layer. The surfaces of the waterproof main strip and the drainage side guide strip are coated with a hydrophobic and diffusing coating. An adhesive layer is provided on the pull tab, and a smooth coating is provided on the inner wall of the anti-detachment strip. The privacy film body is made of silica nanoparticle coating. This improves the water resistance of the privacy film body for business tablets at the connection between the main screen and the default keyboard, and improves the resistance to pull-out of the release film layer on the initially purchased privacy film body.

This utility model discloses a high-reliability connector, including a socket terminal and a plug terminal installed on the right side of the socket terminal, and a stabilizing mechanism. The stabilizing mechanism includes a slot, a plug block, a sliding groove, a locking block, a limiting component, a reset component, and a through groove. The socket terminal has slots on both the front and rear sides of its right side, and the plug terminal has plug blocks on both the front and rear sides of its left side. The plug blocks are inserted into the slots on the same side. A sliding groove is formed on the side of the plug block away from the center of the plug terminal. The locking block is slidably connected to the sliding groove through the limiting component. Through grooves are formed on both the front and rear sides of the socket terminal, and the through grooves communicate with the slots on the same side. The reset component is provided inside each through groove. This high-reliability connector improves the insertion stability between the plug terminal and the socket terminal through the stabilizing mechanism, avoiding the occurrence of the plug terminal and the socket terminal separating due to external influences.
