Safety pin

The invention discloses a safety pin which comprises a pin body, a pin sleeve and a syringe, wherein the pin sleeve is matched with the pin body; the syringe is connected with the pin body; the pin sleeve is axially provided with a chute; the chute comprises a longitudinal slot and a lateral slot which are mutually communicated; the lateral slot comprises a positioning slot and a clamping slot, wherein the positioning slot and the clamping slot are positioned on two sides of the bottom end of the longitudinal slot; one end of the pin body, which approaches to the syringe, is provided with a sliding block; the sliding block is suitable for sliding along the chute; one end of the sliding block, which faces to the clamping slot, is less than one end of the sliding block, which faces to the positioning slot; at least one of the upper side and the lower side of the opening end of the positioning slot, which faces to the longitudinal slot, is provided with a bulge; therefore, the sliding block can conveniently pass through the bulge to enter the longitudinal slot; once the sliding block slides out of the positioning slot, the sliding block can not pass through the bulge to go back to the positioning slot because one end of the sliding block, which faces to the positioning slot, is bigger; and therefore, the safety pin is not suitable to use again.

The invention discloses a polar-axis type solar automatic-tracking system for heating a vacuum heat collector, which comprises a supporting post, two upright posts, a reflector, a transmission device and a driving device and is characterized in that: a movable bracket of the reflector comprises a rail, an inclined rod and a right metal supporting-foot frame which are connected into a whole, a reflector frame and the movable bracket are connected together through a plurality of metal supporting rods, a slot-type cylindrical-surface reflector is installed in the reflector frame, a cylindrical rotating shaft is assembled on the movable bracket, and the rotating shaft is inserted into a self-lubricating bearing sleeve on the supporting post; and the vacuum heat collector which is coaxial with the rotating shaft is installed between an upper fixed ring and a lower fixed ring. The polar-axis type solar automatic-tracking system has the advantages of operation stability, lightened weight, enhanced wind-resisting performance, ultrahigh performance-price ratio and easiness of realization of commercialization; and by adopting a novel polar-axis type one-dimensional tracking mode, the polar-axis type solar automatic-tracking system can realize tracking of a fixed target, improves the light concentrating ratio of the system and reduces the manufacturing cost of a mirror surface.

Interlocking device of grounding switch and front lower door in switch cabinet and switch cabinet

The invention relates to an interlocking device of a grounding switch and a front lower door in a switch cabinet and the switch cabinet. The interlocking device comprises a limiting rod ejector rod and a clamping plate pushing piece; the limiting rod ejector rod has an upward movement trend under the action of a corresponding elastic structure; the limiting rod ejector rod is provided with a blocking position and a receding position in the moving stroke, and the blocking position corresponds to the upper end of the moving stroke of the limiting rod ejector rod and is used for blocking the vertical limiting rod on the switch cabinet from moving downwards; a limiting groove is formed in the outer circumferential face of the limiting rod ejector rod, an ejector rod bayonet is formed in the side, close to the limiting rod ejector rod, of an ejector rod clamping plate, and the ejector rod bayonet is used for being clamped into the limiting groove to limit downward movement of the limiting rod ejector rod when the limiting rod ejector rod is located at the blocking position; and the clamping plate pushing piece is used for pushing the ejector rod clamping plate under the driving of the front lower door when the front lower door is closed, so that the limitation of the ejector rod bayonet in the ejector rod clamping plate on the limiting rod ejector rod is relieved. According to the scheme, the problem that in the prior art, when the front lower door of the switch cabinet is not closed, the grounding switch can still be switched off is solved.
