The invention enables remote control personnel to pay attention to abnormal information more quickly and take corresponding measures, which not only makes the interaction between the equipment and the remote control center and the client more efficient and smooth, but also improves the safety and automation level of device operation. It is suitable for the power supply needs of scattered equipment in oil and gas field engineering.

The invention belongs to the technical field of cloth spreading equipment, and particularly relates to a width-adjustable cloth spreading table. The width-adjustable cloth spreading table comprises a fixed framework and a movable framework, wherein one side of the movable framework extends into the fixed framework; the fixed framework is connected with the movable framework through a drive mechanism; and under action of the drive mechanism, the movable framework moves in the width direction of the fixed framework to move outwards or shrink inwards to regulate width of the cloth spreading table. The width-adjustable cloth spreading table can freely adjust width within a range of 1600mm-2400mm, is suitable for using requirements of any-width fabric within the range, avoids the problem that a cloth spreading table needs to additionally arrange in the prior art for meeting the using requirements, and ensures that machines of different types can be normally used.

The invention discloses a bending type shielded MCU (Micro Control Unit) bus plug and relates to the field of electrical connectors in the field of new energy vehicles, industrial equipment and urban rails and railway vehicle electrical appliances. The bending type shielded MCU bus plug consists of a lower shielding cover, a jack mounting plate, an upper shielding cover, a jack component, a sealing ring, a plug housing, a locking block, a handle, a left shielding cover, a protective sleeve, a right shielding cover, a self-locking nut, a connecting terminal, a shielding cushion cover, a shielding pressure sleeve, a wire sealing body and a tail cover. With the adoption of threaded switchover, bending type wire outgoing is realized; in an assembly state, the two ends of the jack component are respectively fixed in a jack mounting hole and a jack positioning hole of the plug shell; the connecting terminal is rigidly connected with the jack component through connecting threads, so that when a cable is subjected to axial stress, the jack component cannot incline at an inserting position. The bending type shielded MCU bus plug has the advantages of being small in size, good in shielding effectiveness, low in production cost, high in production efficiency, easy to operate, reliable in contact part contact and the like.

The invention discloses an exhibition cabinet lamp with a rotary lamp cap. The lamp comprises a lamp body and a lamp cap which is rotationally connected to the lamp body, and is characterized in that: the bottom of the lamp cap is provided with an elastic driving component; the elastic driving component comprises a spring seat, a positioning pin, a spring and a pressing plate; the positioning pin is accommodated in the spring seat; the spring seat is provided with an end hole through which the head of the positioning pin extends out; the spring is sleeved outside the positioning pin; one end of the spring is axially limited on the positioning pin; a hole cavity is formed on the pressing plate; the spring seat is fixedly arranged in the hole cavity; the other end of the spring is axially limited in the hole cavity; the pressing plate is fixedly connected with the lamp body; and the spring makes the head of the positioning pin always extend out of the spring seat through an end hole and press against the bottom of the lamp cap. By the lamp, elastic pre-tightening force can be generated at the bottom of the lamp cap, the rotating force of the lamp cap can be adjusted by replacing the spring, and the exhibition cabinet lamp has a simple structure and is convenient to mount. Moreover, the lamp cap can be always pressed against the lamp body under the action of the elastic driving component, and the radiating efficiency is improved.

The invention discloses a split-type high-precision all-composite material antenna reflector, which relates to the fields of wireless detection, satellite communication, electronic measurement and control, electronic interference and the like. The antenna reflector is a split-lobe structure, including a center lobe and a plurality of fan-shaped lobes uniformly distributed around the center lobe; the center lobe includes a center reflector panel and a center base fixedly connected to the back of the center reflector panel, a plurality of long Reinforcing ribs and multiple short reinforcing ribs; the fan-shaped petals include fan-shaped reflective panels and reinforcing ribs fixedly connected to the back of the fan-shaped reflective panels; the center petal and fan-shaped petals and multiple fan-shaped petals are connected in a detachable manner; the center The reflective panel and multiple fan-shaped reflective panels together form the reflective panel of the antenna reflector. The invention optimizes the split form of the large-diameter antenna, and at the same time integrates the design of the reflective panel and the reinforced back frame, has a stable structure, and is convenient for the transportation, erection and operation of the antenna reflector.

The invention relates to organic silicon resin encapsulant of large power LED and a preparing method thereof. The encapsulant is prepared by mixing composition A containing vinyl-containing polysiloxane as basic resin, composition B containing vinyl polysiloxane thinning agent, composition C containing hydrogen-containing polysiloxane, platinum catalyst composition D, catalytic inhibitor composition E and tackifier composition F; and the organic silicon resin encapsulant with high refractive index is obtained, and can be used for the encapsulation of various large power LEDs and the potting of other optical purposes. The method solves the problems of the increasing of resin molecular weight and the dissolving preparation of high molecular weight, and the like, by adopting thinning agent method, changes the toughness of resin by adopting cyclosiloxane as cross linker, and improves and maintains the refractive index by adopting refinement method. The method has the advantages that single component package mode and double component package mode can be prepared, the adaptability and the efficiency of encapsulation equipment and processing procedure can be improved, the cost is reduced, and the use is convenient.

The invention discloses a curved high-voltage shielding plug, which relates to the field of electrical connectors in the electrical fields of new energy vehicles, industrial equipment, urban rail and railway vehicles. It includes housing assembly, contact and mounting plate assembly, tail attachment. The shell assembly is composed of a locking handle, a lock block, a plug shell, a sealing ring, and a signal pin. The locking and unlocking of the connector is realized by using the mechanism that converts the rotary motion of the handle into the linear motion of the plug shell relative to the socket shell, and can normally use the electrical connector in the case of a relatively narrow operating space, which solves the problem of traditional electrical connection The locking method of the connector cannot be used normally in a narrow operating space. At the same time, the handle also has a power-assisted effect, which improves the ease of operation of the connector.
