The invention discloses a data transmission method, a transfer server and an access network point server, wherein the method includes: establishing a first TCP connection with a central network point server, and connecting the established first TCP connection with the central network point The network point identification association storage of server; Establish a second TCP connection with the acceleration server, and receive the SSL connection request directed to the central network point server forwarded by the acceleration server through the second TCP connection; according to the network point identification of the central network point server, Binding the second TCP connection and the first TCP connection, so as to transmit the encrypted data between the access network point server and the central network point server through the first TCP connection and the second TCP connection data. The technical solution provided by this application can improve the security of data transmission.

The invention relates to a valve core of a three-position three-way valve. The valve core comprises a cylindrical body internally provided with a first water flow passage in the axial direction; an annular bush rotatably sleeves the body; a second water flow passage is formed between the bush and one end of the body under the wrapping of a valve; a third water flow passage is formed between the bush and the other end of the body. The bush can detachably sleeve the body of the valve core and the bush can rotate relative to the body without sliding, so the valve core has the advantage that the thickness of the plastic valve core can be controlled compared with the mode that the bush is integrally molded on the body of the valve core, the surface of the plastic valve core is smooth, the airtightness between the valve core and the valve is better, the valve core is not easy to deform and can not cause the staggering of the water flow passages when moving in the valve, the plastic bush can be replaced and the product cost and the use cost are greatly reduced.

The invention discloses an intelligent winch and a control method thereof, and relates to the technical field of winches. The intelligent hoist and its control method include a hoisting device, an anti-falling device, a linkage device and a guiding device. A rotating column is movably connected in the middle of the rear surface of the flap, and a vertical plate 1 is movably socketed at the rear end of the rotating column. The front end is movably connected with the vertical plate 2, the rear surface of the vertical plate 2 is fixedly connected with the base plate, the front surface of the vertical plate 1 is fixedly connected with the base plate, the left end of the upper surface of the base plate is fixedly connected with the vertical plate 3, and the right end of the upper surface of the base plate is fixedly connected with a sleeve. The upper surface of the barrel sleeve is movable and connected with a movable column. Turn on the motor to drive the output shaft to rotate, and the rotating plate will rotate counterclockwise under the rotation of the output shaft. When the machine pulls heavy objects with a large mass, machine failures are prone to occur, resulting in Rapidly falling, at this time the left end of the flap is pressed downward, and when the flap turns to the upper end of the third vertical plate, it stops, preventing the heavy objects from continuing to fall, and ensuring the safety of the operator.

The invention belongs to the field of mine underground illumination equipment and relates to an illumination bracket device. The illumination bracket device comprises a lamp holder support body, a stand column and a base. The lamp holder support body comprises four support rods. One ends of the four support rods are connected together. Each support rod is provided with a lamp holder. The stand column comprises a first-level column and a second-level column. The second-level column is mounted inside the first-level column in a sleeved manner, and in addition, the first-level column is providedwith an adjustment bolt. The top end of the second-level column is fixedly connected with connecting ends of the four support rods. The bottom end of the first-level column is fixedly connected with the base. By means of the illumination bracket device, 360-degree full illumination can be achieved; in addition, the height of an illumination bracket can be adjusted; and the requirement that the underground illumination height is varied frequently can be met.

The invention provides a pulling plate type magazine discharging device which comprises a frame located above the production line, and is characterized in that a magazine supporting mechanism, a pulling plate mechanism, a magazine locking mechanism, an unloading conveying mechanism and a discharging mechanism are arranged on the frame, and the pulling plate type magazine is arranged on the magazine supporting mechanism. Cigarette rods on spot check can be collected and stored conveniently and flexibly in any position of the production line through the pulling plate type magazine; and materials in each pulling plate type magazine on the production line can be gathered and automatically discharged onto the production line through the discharging device provided by the invention; therefore, the labor intensity is effectively reduced; and in the discharging process, the pulling plate type magazine discharging device is regular in unloading without disorder and without damaging cigarette rods, stable and reliable, free of space occupation, and advantageous for promoting full automatic production procedure.
