Abstract

The utility model relates to the field of speed reducers and aims to provide a speed reducer which is adjustable in self-height during mounting and has the advantages of simple structure and convenience in use. The technical scheme includes that the speed reducer with mounting height adjustable comprises a reducer body and a base, and is characterized in that heightening plates capable of turning are mounted at the left side edge and the right side edge of the base respectively via hinge structures. Each hinge structure comprises a crossbar, a connecting rod and a connecting plate, the crossbars are fixed at the left side edge or the right side edge of the base, the connecting plates are fixed at the edges of the heightening plates and provided with slide grooves stretching along the thickness direction of the heightening plates, one ends of the connecting rods are hinged to an extending end of the crossbar via first hinge shafts, the other ends of the connecting rods are hinged to the connecting plates through second hinge shafts, and the second hinge shafts are slidably mounted in the slide grooves. The length extending direction of the heightening plates extends in parallel to the left side edge or the right side edge of the base.

Description

The speed reducer that a kind of setting height(from bottom) is adjustable

Technical field

The utility model relates to speed reducer technical field, the adjustable speed reducer of especially a kind of setting height(from bottom).

Background technique

Speed reducer conventionally with the collocation use such as motor, diesel engine, in installation process, because the output shaft of the input shaft of speed reducer and motor, diesel engine is not contour, or it is not contour between the output shaft of speed reducer and the input shaft of actuator, need to regulate the setting height(from bottom) of speed reducer, normally additionally increase a base or add and increase piece below the base of speed reducer, base and increase piece and carry comparatively inconvenience, install also and comparatively bother, wait to improve.

Model utility content

The purpose of this utility model is the deficiency overcoming in above-mentioned background technology, provides a kind of setting height(from bottom) adjustable speed reducer, and this speed reducer should regulate the height of self when mounted, and has feature simple in structure, easy to use.

For realizing above object, the utility model has adopted following technological scheme:

The speed reducer that setting height(from bottom) is adjustable, comprises body and base, it is characterized in that: the edge, left side of described base and right edge are along clearly by hinging structure, the turnover plate that increases not being installed.

Described hinging structure comprises cross bar, connecting rod and connecting plate, cross bar is fixed on edge, left side or the right edge edge of base, connecting plate is fixed on and increases the edge of plate and offer the chute stretching along increasing plate thickness direction, one end of connecting rod is hinged on the external part of cross bar by the first hinging shaft, the other end of connecting rod is hinged by the second hinging shaft and connecting plate, and this second hinging shaft is slidably mounted in described chute.

The described length extending direction of plate and the edge, left side of base or right edge of increasing is along extends parallel.

The described plate that increases offers the through hole corresponding with the screw of base.

The beneficial effects of the utility model are: the utility model by base edge hinged one increase plate, need to increase when height, will increase plate and stir the bottom of base, while not needing to increase highly, can will increase plate retailer to the end face of base, fixing with bolt.

Embodiment

Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.

As Figure 1-Figure 4, the adjustable speed reducer of a kind of setting height(from bottom) described in the utility model, comprises body 1 and base 2, and the edge, left side of described base and right edge are along clearly by hinging structure, the turnover plate 4 that increases not being installed.

Edge, described left side and right edge are along being equipped with two hinging structures, and two hinging structures lay respectively at the front-end and back-end on edge, left side or right edge edge.Hinging structure comprises cross bar 7, connecting rod 5 and connecting plate 4-1, and cross bar is fixed on edge, left side or the right edge edge of base, and connecting plate is fixed on and increases the edge of plate and offer the chute 4-2 stretching along increasing plate thickness direction.One end of connecting rod is hinged on the external part of cross bar by the first hinging shaft 6-1, the other end of connecting rod is hinged by the second hinging shaft 6-2 and connecting plate, this second hinging shaft is slidably mounted in described chute, and when upset, the second hinging shaft slides into the other end from one end of chute.

The described length extending direction of plate and the edge, left side of base or right edge of increasing, along extends parallel, increases the width of plate and determines as required.The described plate that increases offers the through hole corresponding with the screw of base 3, and when increasing plate and upwards turning over or turn over downwards, the through hole that increases through hole on plate and base is right up and down.

The length of described connecting rod is at least the half of the thickness of base, can fit better with the end face of base and bottom surface in the process of turning over up and down thereby make to increase plate.

Claims
