Abstract

The utility model discloses a pentahedral overturning mechanism, which consists of a base, a gear motor, a spiral elevator, a bracket, a connecting block, connecting rods, rotating shaft bearings, four support arms and antennae, wherein the base is welded by a steel plate into a whole; the antennae and the rotating shaft bearings are arranged on the support arms respectively; the support arms are distributed on the four lateral surfaces of the bracket; four support lugs are fixedly connected with the top surface of the bracket, and serve as the centers of gyration of the support arms; another shaft holes of rotating shaft bearings are hinged with the connecting rods through shaft pins; the four connecting rods are simultaneously hinged with the connecting block through the shaft pins; the connecting block is fixedly connected with the top end of a screw rod of the spiral elevator; and the spiral elevator is fixed on the bottom surface of the bracket. The pentahedral overturning mechanism is simple and rational in structure, easy to manufacture, convenient to assemble, reliable in strength and flexible in overturning; production cost is saved; and production efficiency is improved.

Description

Five switching mechanisms

Technical field

The utility model relates to a kind of five switching mechanisms, belongs to the plant equipment field.

Background technology

Switching mechanism generally is used for the various device of mechanical industry, but is not also appearing in the newspapers aspect the technical field of the switching mechanism that is used for the antenna expansion or draws in.

The utility model content

The purpose of the utility model is in order to overcome deficiency of the prior art, thereby a kind of five switching mechanisms are provided.

Five switching mechanisms are made up of base, reducing motor, spiral lift, support, contiguous block, connecting rod, shaft support, support arm and antenna; Said base is welded as a whole with steel plate; Shaft support and support arm, antenna are mounted to integral body; Totally four parts; Arrange on four sides of supports by 90 ° of directions respectively, is connected with screw mandrel on the spiral lift, form a switching mechanism that can rotate simultaneously on four sides through the rotating shaft on the support, connecting rod and contiguous block and support; Said support arm has four, fixes up an aerial wire respectively and shaft support on the supporting arm, is arranged in four sides on the support; Cradle top surface is fixedly connected with four journal stirrups; As the centre of gyration of supporting arm, another axis hole of shaft support and connecting rod carry out hinged through pivot pin, and four connecting rods are hinged on the contiguous block through pivot pin simultaneously; Contiguous block is fixedly connected with spiral lift screw mandrel top, and spiral lift is fixed on the bottom surface of support.

Adopt the beneficial effect of technique scheme to be:

The utility model is simple and reasonable, makes easily, and is easy to assembly, practiced thrift production cost, and improved production efficiency, and intensity is reliable, the upset easy and flexible.

Description of drawings

Fig. 1 is five switching mechanism structural representations of the utility model.

Among the figure: 1-base, 2-reducing motor, 3-spiral lift, 4-support, 5-contiguous block, 6-connecting rod, 7-shaft support, 8-support arm, 9-antenna.

Embodiment

Below in conjunction with accompanying drawing the utility model is done further explain.

Five switching mechanisms are made up of base 1, reducing motor 2, spiral lift 3, support 4, contiguous block 5, connecting rod 6, shaft support 7, support arm 8 and antenna 9; Said base 1 usefulness steel plate is welded as a whole; Base 1 has relative motion relation with support 4, through gear drive drive support 4 and on member do whole gyration, realize integral level and flip vertical function.Shaft support 7 is mounted to integral body with support arm 8, antenna 9; Totally four parts; Arrange on four sides of support 4 by 90 ° of directions respectively; Be connected with screw mandrel on the spiral lift 3 through the rotating shaft on the support 4, connecting rod 6 and contiguous block 5 and support 4, form one can the four sides switching mechanism of rotation simultaneously, realize four sides upset simultaneously; Said support arm 8 has four, fix up an aerial wire respectively on the supporting arm 89 with shaft support 7, be arranged in four sides on the support 4; Support 4 end faces are fixedly connected with four journal stirrups; As the centre of gyration of supporting arm 8, another axis hole of shaft support 7 and connecting rod 6 carry out hinged through pivot pin, and four connecting rods 6 are hinged on the contiguous block 5 through pivot pin simultaneously; Contiguous block 5 is fixedly connected with spiral lift 3 screw mandrel tops, and spiral lift 3 is fixed on the bottom surface of support 4.

The gathering process of five switching mechanisms of the utility model relies on the effect of spiral lift 3, and screw mandrel moves downward along support 4 straight lines; Contiguous block 5 drivening rods 6 that are connected the screw mandrel top move downward; Drive four shaft supports 7 and do gyration, the supporting arm 8 that is connected on the shaft support 7 is just done gyration with shaft support 7 together with antenna 9, makes supporting arm 8 and antenna 9 rotate to be the upright position from horizontal level; Spiral lift 3 quits work then; Reducing motor 2 begins starting, and drive support 4, supporting arm 8, antenna 9 rotate together, make supporting arm 8 rotate to horizontal level.

The expansion process of five switching mechanisms of the utility model is gathering process inverse process, and at rounding state, reducing motor 2 begins counter-rotating; Drive support 4, supporting arm 8, antenna 9 and rotate together, make supporting arm 8 rotate to the upright position by horizontal level, reducing motor 2 quits work then; Start spiral lift 3, screw mandrel moves upward along support 4 straight lines, and contiguous block 5 drivening rods 6 that are connected the screw mandrel top move upward; Drive four shaft supports 7 and do gyration; The supporting arm 8 that is connected on the shaft support 7 is just done gyration with shaft support together with antenna 9, makes supporting arm 8 and antenna 9 rotate to be horizontal level from the upright position, and expansion process is accomplished.
