The invention relates to an integrated lock structure with a back-locking function. The integrated lock structure with the back-locking function is formed by a lock body, a lock cylinder, an externalpanel and a built-in panel. According to the integrated lock structure with the back-locking function provided by the invention, the lock cylinder is only connected to the external panel, and only half section of lock cylinder is adopted to connect and act on the lock body, so that the composite cost of the lock cylinder is saved by half. The integrated lock structure with the back-locking function provided by the invention is convenient to use, and can be directly lifted up for back locking and downwards pressed for unlocking, so that the step of using a key for back locking is saved, and thefunctions of the lock cylinder and back locking are replaced. During an application process of the lock structure, a user can easily back-lock a door, so that a safety performance of the lock body isimproved. Meanwhile, when an emergency situation happens and people needs to escape, one-button door opening is realized, so that a remarkable escape function is realized. In addition, a back-lockingbutton can be started inside a door so as to realize back locking, and the door cannot be opened by using a key outside the door, so that a safety performance of the lock body is greatly improved.

The invention discloses a line pressing and groove pressing die of a door sheet. The line pressing and groove pressing die specifically comprises an upper die body, a 90-degree pressing die body, a middle die body and a lower die body. A first fixing frame is arranged at the top of the upper die body. A first square tenon is arranged at the bottom of the upper die body. A second fixing frame is arranged at the top of the 90-degree pressing die body. A 90-degree tenon is arranged at the bottom of the 90-degree pressing die body. A first square mortise groove and a 90-degree mortise groove are formed in the top of the middle die body. A second square mortise groove is formed in the top of the lower die body. In the application process, the process that various grooves and lines are pressed into various models is carried out at a time; and meanwhile model data are stable, and work efficiency is extremely high. By means of the line pressing and groove pressing die, a panel does not need to be overturned back and forth, and therefore the panel can be kept without various scratches or concave-convex points. In addition, the line pressing and groove pressing die is simple in structure and low in manufacturing cost, but the application effect is remarkable, and a plurality of models can be pressed through one die.

The invention discloses a bathroom door leaf glass frame. The bathroom door leaf glass frame specifically comprises a door frame, a door frame lace and a rubber strip-glass fixing clamp, wherein fast bolt tracks are correspondingly arranged at the upper and lower ends of the rubber strip-glass fixing clamp. In the bathroom door leaf glass frame, the fast bolt tracks are correspondingly arranged at the upper and lower ends of the rubber strip-glass fixing clamp, so that during mounting, rubber strips and glass firmly fit the door leaf glass frame better, do not get loose and are not liable to move away from the right positions; besides, in the bathroom door leaf glass frame, the door frame lace is arranged, so that the integral structure of a door body is quite beautiful, and the commodity value of the door is improved.

A double-working hinge specifically comprises a tight hinge body, a loose hinge body, a movable shaft, an upper plug and a lower plug, wherein the movable shaft is sleeved with the tight hinge body and the loose hinge body, the upper plug is sleeved with the tight hinge body, and the lower plug is sleeved with the loose hinge body, so that the whole double-faced hinge is formed. According to the double-working hinge, the tight hinge body and the loose hinge body are each provided with six screw holes. When a door and a door frame are combined through the double-working hinge, the double-working hinge is not prone to being prized up by people. When the double-working hinge is applied, the door frame and a door sheet can be split, and mounting is convenient. Meanwhile, when the double-working hinge is applied, the door is not prone to drooping or rebounding.

An automatic door frame molding machine with different specifications specifically comprises a machine frame, a door frame movable molding wheel assembly, a molding idler wheel power motor, a walking motor, a rotary shaft, a locking control lever, a positioning and locking frame, a precise guide shaft, a dividing ruler, a locking spanner, a gear sliding rail, a guide shaft rail, a first chain, a second chain, a bearing block and a gear. By the adoption of the machine, a plate can be molded into a door frame at a time. Furthermore, the specification of the door frame can be adjusted freely according to different requirements. Therefore, door frames matched with different walls can be made. Besides, working efficiency is quite high, and efficacy is over five times that of a traditional molding machine.

The invention provides an anti-corrosion composite layer, which sequentially includes an amorphous alloy layer, an anti-corrosion connecting layer and an acid-resistant ceramic layer. Preparation method of anti-corrosion composite inner lining for pipeline or container. The anti-corrosion composite layer provided by the invention has a novel structural composition, the structure is easy to form, firm and stable in combination, adjustable in thickness, and has excellent corrosion resistance, and has multiple protective effects against special working conditions in the fields of chemical industry, metallurgy and the like. It can be used as the inner lining of pipelines, containers and other equipment, especially suitable for the "one-step acid-dissolving method" of fly ash to produce alumina.
