The invention relates to the field of illumination lamp technology, in particular to a luminaire with a light source which can retractably rotate in the luminaire. The retractable luminaire comprises a luminaire shell and a light source component which is arranged in the luminaire shell; the luminaire shell comprises two slideways which are arranged correspondingly; each slideway is provided witha positioning part; the light source component is fixedly provided with an elastic position-limit part; and the elastic position-limit part is matched with the positioning part of the slideway so as to lead the light source component to move along the slideway and to be positioned at corresponding positions. The matching structure leads the part of the light source of the luminaire to be positioned freely at different positions of the luminaire shell and leads the operation and usage to be more convenient. Furthermore, the retractable luminaire realizing the retractable structure of the lightsource component mainly adopts a spring for positioning, therefore, the movement and position are exact and the hand-feeling of the operation and usage is good.

The invention relates to a straight-movement AC(Alternating Current) contactor with a lock catch arranged at the center, belonging to the technical field of low-voltage electric appliances. A moving contact is mounted on a moving mortice core, and a stationary contact is fixed on a stationary contact fixing stand which is fixed on a contactor base; a stationary magnet fixed on the contactor base is arranged between a hanger plate and the contactor base; and two attracting coils are arranged on the stationary magnet. The straight-movement AC contactor is characterized in that a lock catch mechanism is arranged at the central position of the stationary magnet between the two attracting coils; the lock catch mechanism comprises a spring bolt and a lock pin which is fixed on the hanger plate; the spring bolt is connected onto a brake separation tripping rack, and the brake separation tripping rack can restore automatically and is installed on a lock catch seat ; the lock catch seat is fixed on the stationary magnet; a brake separation tripper is correspondingly arranged at the outer end of a tripping force arm of the brake separation tripping rack; and the lower end of a stripping rod of the brake separation tripper contacts with the tripping force arm. The straight-movement AC contactor consumes no electric power and produces no noise during operation; the coils and the contacts can not easily be burned; and the straight-movement AC contactor is small in size, little in occupying room, and reasonable and compact in structure and is sensitive and reliable.

The invention relates to an intelligent control multi-point locating track-type video monitoring system. The system comprises an intelligent operation keyboard control circuit, a front-end control and video switching circuit and a movable locating device; a camera is installed on the movable locating device in a hoisting way, and the movable locating device is controlled by the front-end control and video switching circuit to realize remote control, and the camera can rapidly reach to the corresponding observation point for observation through the presetting of the observation point. The system is suitable for occasions with severe working conditions, higher risks and need to observe corresponding working equipment and greatly reduces the working risk and the labor intensity of field operators in large and medium-sized industrial and mining enterprises.

The object of the present invention is to provide a working method of a sorting device, which is used to solve the technical problem of sorting objects. A working method of a sorting device, comprising the following steps: S1, objects are driven forward by a conveying mechanism; S2, a pick-up mechanism acquires the objects on the conveying mechanism; S3, the moving positioning mechanism drives the pick-up mechanism to move and position to the corresponding position of the docking mechanism. Position; the S4 pushing mechanism pushes the objects on the picking mechanism into the docking mechanism.

The invention relates to a spot welding machine with accurate positioning of sleeves, which includes a frame and a power distribution control box. The frame is provided with a positioning device, a clamping mechanism and a welding mechanism that cooperate with the sleeve. The positioning device includes a There are two positioning seats on the support, one of the positioning seats is provided with a positioning insertion shaft on the outside of the positioning seat, and a positioning top is installed on the positioning seat to cooperate with the matching groove opened on the side of the sleeve. Rod, the positioning ejector rod is tangentially matched with the upper and lower sides of the matching groove, and the positioning ejector rod is matched with the ejector rod movable device provided on the positioning seat; The matching clamping mechanism is clamped, and the positioning of the sleeve is realized by the positioning ejector rod matched with the matching groove, and the rotation of the sleeve is avoided at the same time, ensuring that the sleeve does not deviate during the spot welding process and improving the The accuracy of spot welding, and facilitate the blanking of the sleeve.
