The invention discloses a rail cable fixing device which comprises steel rail clamps and cable clamps, wherein the steel rail clamps are fixed on the surface on the outer side of the bottom of a steel rail; the cable clamps are arranged on the outer sides of the steel rail clamp attachment surfaces of the steel rail clamps and are used for fixing cables. Hangnails are arranged on the inner side of the steel rail, located at the bottoms of the steel rail clamps, and used for tightly binding the surface of the bottom of the attached steel rail. The rail cable fixing device solves the technical problems in the prior art that objects needing to be positioned cannot be effectively fixed on the condition that the steel rail is not suitable for being fixed by bolts, and the requirement on synchronously mounting one or more than one identical or different objects under the condition of changing attachments cannot be satisfied.

The invention discloses cross threads arranged in a nut. The wall surface of a through hole sinks towards the outer wall of a nut body to respectively form left-hand threads and right-hand threads, the crest of any circle of left-hand thread in the left-hand threads is correspondingly intersected with the root of a circle of right-hand thread in the right-hand threads, adjacent longitudinal cross points are connected with a transverse cross section between the adjacent longitudinal cross points to form a pyramid structure, the pyramid top faces the outer wall of the nut body, the left-hand threads and the right-hand threads are machined on the inner wall of the through hole, the crest line of each circle of left-hand thread is intersected with the root line of the right-hand thread on the same height as the left-hand thread to form a plurality of rhombuses, and the two inclined surfaces of the left-hand threads cut the two inclined surfaces of the right-hand threads to form four through prismatic sides to form the pyramid structure with cross threads. According to the cross threads, the left threads and the right threads on a screw stem can be conveniently screwed into a hinge ball threaded hole through the added pyramid structure, the application range is widened, and the stress of the threads meets the requirements on mounting.

The invention discloses an adjustable portable equipment support in the technical field of electrical equipment. The adjustable portable equipment support comprises two cross frames, wherein a hand holding handle is installed on one side wall of each cross frame; two ends of the cross frames are connected with traverse shifting telescopic frames; one end of each traverse shifting telescopic frameis movably connected to the inner cavity of the corresponding cross frame through a fixed block in an inserted manner; a sliding groove is formed in the upper part of each cross frame; each fixed block is arranged at the upper part of the corresponding sliding groove; installation plates are installed at the other ends of the traverse shifting telescopic frames; the outer walls of the traverse shifting telescopic frames are connected with longitudinal shifting telescopic frames through connecting pieces; the two traverse shifting telescopic frames are connected with longitudinal frames throughthe longitudinal shifting telescopic frames; an active double-screw bolt is in screw joint between the two longitudinal frames; one end of the active double-screw bolt is connected with an adjustinghandle; and a lifting double-screw bolt is in screw joint inside each longitudinal frame. The requirement of installation among all the electrical equipment is met, and the electrical equipment does not need to be dismounted and mounted repeatedly, so that the support is simple in structure, low in cost and convenient to carry, and the requirement of installation for workers is met.

The present invention relates to the field of hardware technology, in particular to a combined hardware connector, which includes a connector body, the connector body is composed of a connecting plate A and a connecting plate B; the connecting plate A includes a connecting plate A body, so A protrusion A is set in the middle of the surface of the connecting plate A body, and several grooves are uniformly arranged around the surface of the connecting plate A body; the connecting plate B includes the connecting plate B body, and the middle part of one end of the connecting plate B body is set There is a protrusion matching the groove of the body of the connecting plate A, and a protrusion B is set in the middle of the surface of the connecting plate B body; it can be combined into a straight shape, a positive and negative L shape, a T shape and a cross shape to meet the requirements of the partition wall. According to the needs of installation, the utility model has the advantages of simple structure, convenient combination and installation, and can reduce production cost.

The invention belongs to the technical field of pin type insulators, and discloses a rotatable pin type insulator, and aims to solve the problem that an existing pin type insulator does not have the functions of winding, unwinding and fastening a cable and the problem that a wire clamping head at the top of the insulator cannot be disassembled and assembled at the same time. The rotatable pin type insulator comprises a pin type insulator body, the bottom of the pin type insulator body is provided with a connecting threaded pin, the surface of the connecting threaded pin is connected with a fixing nut, the top of the pin type insulator body is provided with a connecting rod, the top of the connecting rod is provided with a fixing block, and the top of the fixing block is provided with a cable winding disc. According to the pin type insulator, rotation adjustment can be effectively carried out, so that a cable can be effectively wound, unwound and fastened, the cable installation efficiency is improved, meanwhile, a cable clamping head of the pin type insulator can be effectively installed and detached, the use performance and practicability of the pin type insulator are improved, and the use and maintenance of the pin type insulator are facilitated.

The invention provides an all-functional cooking robot and belongs to kitchen utensils. The all-functional cooking robot is characterized in that a combustor is arranged on a base seat of a frame; a frying pan slide track which is inclined upwards is fixed on a beam on one side of the frame; the lower end of a frying pan suspension arm is vertically connected with a frying pan handle in a clearance fit manner, and a frying pan slide block at the middle is in slide and clearance fit with the frying pan slide track; a reversible frying pan motor is vertically fixed at the upper end of the frying pan slide track; a vertical track is arranged on the other side of the frame; a reversible slotted spoon motor is arranged at the lower end of the vertical track; a reversible slotted spoon motor chain wheel is connected with a second slotted spoon chain wheel at the upper end of the vertical track through a slotted spoon chain; a slotted spoon slide block is fixed on the slotted spoon chain; the slotted spoon slide block is fixed with a slotted spoon transverse arm; and one end of the slotted spoon transverse arm is in lateral clearance fit with a slotted spoon handle. The all-functional cooking robot can finish dish frying automatically, and the process and the procedures conform to the manufacturing requirements of dishes, so that the manufacturing of basic dishes of kitchens can be realized; a frying pan can be controlled to move linearly in a horizontal plane, and dishes can be turned over in the frying pan; small space is required for cooperation of the frying pan and the slotted spoon, and the size of a cooking bench is small, so that the requirements on household installation can be met, and the cooking robot is favorable for popularization in the commercial field.
