The invention discloses an Internet sensor connection head, which comprises a joint body and an insulating shell. The upper end and the lower end of the joint body are respectively provided with a first interface and a second interface. The insulating shell is sleeved on the outside of the joint body. The insulating shell consists of The fastening casing is composed of a lower casing, a transition casing and an upper casing. The fastening casing is set on the outside of the second interface. Several oblique through holes are arranged on the outer surface of the fastening casing. An oblique arc guide plate is fixedly connected to one end of the through hole, and the oblique arc guide plate is located inside the lower casing, and a moving column is fixedly connected to the side of the upper end of the rubber rod. In the present invention, through the setting of oblique through holes, oblique arc guide plates, rubber rods and moving columns, after the second interface is connected with the connecting device, the moving collar is pushed to make the rubber rod slide along the oblique arc guide plates to the oblique passage. In the hole, the rubber rod is in close contact with the inner side wall of the equipment interface, so that the present invention is not easily separated from the equipment interface.

The invention discloses a method for preparing a 6,6'-bi(2,3-dimethoxyphenyl)-alpha,alpha-D-trehalose intermediate. The method comprises the following steps: (1) dissolving 2,3-dimethoxybenzoic acid in anhydrous tetrahydrofuran, adding N,N'-carbonyl diimidazole, stirring at room temperature, and performing carboxyl activation; (2) adding a compound shown as a formula II and N-bromo-succinimide in a catalytic amount into the reaction solution subjected to carboxyl activation in the step (1), stirring and reacting; and (3) adding water into the solution reacted in the step (2), stirring for 10-15 minutes, extracting for three times by using dichloromethane, mixing the organic layers, washing for three times by using a saturated potassium carbonate aqueous solution, washing by using saturated salt, drying by using anhydrous sodium sulfate, filtering, concentrating, recrystallizing the residues by using ethanol / water, thereby obtaining the 6,6'-bi(2,3-dimethoxyphenyl)-alpha,alpha-D-trehalose intermediate, removing the trimethylsilyl of the intermediate under weakly acidic conditions, thereby obtaining 6,6'-bi(2,3-dimethoxyphenyl)-alpha,alpha-D-trehalose. The method disclosed by the invention is mild in reaction conditions, low in cost and suitable for industrial production.

The invention discloses a combined jute blocking paster. The combined jute blocking paster comprises a main body and a jute eyelet fabric covering the main body, wherein the main body comprises an outer blocking ring and an inner blocking ring; the outer blocking ring and the inner blocking ring are connected with each other and concentrically arranged; the outer blocking ring has a first cylindrical body group obliquely and upwardly extending towards the outer side of the outer blocking ring from the upper surface of the outer blocking ring; the inner blocking ring has a second cylindrical body group vertically and upwardly extending from the upper surface of the inner blocking ring; and the first cylindrical body group and the second cylindrical body group penetrate the jute eyelet fabric. According to the invention, the jute eyelet fabric sleeves the main body in a covering manner; the oblique first cylindrical body group penetrates the jute eyelet fabric and downwardly presses thejute eyelet fabric to restrain the jute eyelet fabric between the first cylindrical body group and an installing surface, so the jute eyelet fabric is difficult to be divorced from the first cylindrical body group; the second cylindrical body group extending vertically and upwardly allows water current to pass through and can hook hair flowing with water, so hair is collected to a place nearby thepaster.

The invention belongs to the technical field of communication equipment, and particularly relates to a communication networking device based on a security key. The device comprises a data interface module and a controller, the data interface module comprises a network interface module and a voice interface module for transmitting audio signals, and the controller comprises an interface selection module, a storage module, a service processing module and an interface switching module; the device also comprises a modulation decoder and a network connector. The modulation decoder provides hardwaresupport for the data interface module and the controller. The network connector is physically connected with the modulation decoder and transmits data to the modulation decoder, and the network connector can quickly change the connection position when the interface switching module carries out an interface switching instruction; the connection position of the network connector is adjusted in themodulation decoder, so that the network communication error caused by the insertion error of the network connector slot can be automatically solved.

The invention discloses an electric signal transmission device for preventing electrodes from falling off, which includes a casing, the interior of which includes an electric signal transmission body, and a plurality of first springs arranged on one side of the interior of the casing, and several first springs. The springs are all separated by partitions, and the upper and lower ends of the first spring are provided with clamping ports, and the contraction air bag can be inflated when the electrode plug is inserted into the connection hole of the electrode end through the provided contraction air bag, so that The anti-slip ring wraps the electrode plug to fix the electrode. When the electrode plug is loose, the anti-slip ring wrapped around the electrode plug is driven by the electrode plug to move outward so that one end of the limiting plate leaves the inside of the first spring, and the limiting plate leaves the first spring. The internal contact port of the spring is simultaneously displaced to contact with the second electrical terminal on one side of the partition to be energized, so that the first indicator light electrically connected to the contact port is energized and illuminated, thereby performing a light warning.
