This utility model discloses a valve ball grinding and positioning device with an anti-displacement structure, including a positioning frame. A back frame for mounting and fixing grinding tools is fixed on the back of the top of the positioning frame. Square columns are inserted into the top of both sides of the positioning frame. A reinforcing shaft is rotatably installed in each set of square columns. A fixing cone for inserting into the inner cavity of the valve ball is fixed at one end of the reinforcing shaft that is close to each other. An anti-displacement component is provided on the positioning frame to cooperate with the fixing cone and position the valve ball. By setting the anti-displacement component, this utility model can autonomously and multi-directionally position the valve ball on both sides and inside according to the size of the valve ball. At this time, the multi-directional and multi-means positioning method improves the positioning stability of the positioning device for the valve ball, effectively avoids the valve ball from easily shifting during the grinding process, and greatly improves the grinding effect of the grinding tool on the surface of the valve ball.

This utility model discloses a mold closing mechanism with a composite ejector cylinder, including a moving mold plate, which has a mold plate body and an outwardly extending protruding structure. The protruding structure is equipped with at least one main ejector cylinder and at least two auxiliary ejector cylinders, the stroke of the main ejector cylinder being greater than the stroke of the auxiliary ejector cylinders. An ejector guide plate is provided between the mold plate body and the protruding structure. The piston rod of the main ejector cylinder is connected to the ejector guide plate, while the piston rod of the auxiliary ejector cylinders is not connected to the ejector guide plate. Several ejector rods are provided on the ejector guide plate, penetrating the mold plate body. During the stroke of the auxiliary ejector cylinders, the main ejector cylinder and the auxiliary ejector cylinders together drive the ejector guide plate to complete the ejection action of the ejector rods. During the remaining stroke, the main ejector cylinder alone drives the ejector guide plate to complete the ejection action of the ejector rods. This mold closing mechanism with a composite ejector cylinder can provide a large ejector force in the initial demolding stage and achieve rapid ejection in subsequent strokes, combining large ejection force and high movement speed to improve production efficiency.

This utility model provides a roller-type multi-axis fire-resistant roller shutter for small spaces, which is a double-track, double-curtain fire-resistant roller shutter. The fire-resistant roller shutter includes a frame and a drive device. The frame is composed of two support plates and two fixing rods. Several rollers are evenly spaced within the frame. The roller on one edge is the starting roller, the roller on the other edge is the first roller, and the roller adjacent to the first roller is the second roller. The drive device is connected to the starting roller within the frame. Two layers of roller shutters are rolled up on the starting roller: the upper layer is the first roller shutter, and the lower layer is the second roller shutter. This utility model provides a roller-type multi-axis fire-resistant roller shutter for small spaces, which has lower cost, occupies less installation space, and compared with traditional double-track, double-curtain fire-resistant roller shutters, has a longer fire resistance time and better heat insulation and smoke prevention effects.

This application provides an optical component and its assembly method. By fixing a third lens portion with its optical axis as a reference, the positions of the first and second lens portions are simultaneously adjusted. Based on the sensitivity of the optical lenses, the first lens portion, with higher sensitivity, is first fixed to the housing of the driving device. Then, the position of the second optical lens portion, with lower sensitivity, is adjusted. Finally, after the second lens portion can clearly image the image, it is fixed to the focusing carrier of the driving device, thus forming the optical component described in this application. This assembly method simplifies the assembly process while ensuring the accuracy of the assembled optical component.
