Abstract

The utility model discloses a handrail angle demodulator, insert the tip, its characterized in that including bearing, grafting support pad and stopping: the bearing is the internal spline shape, installs on bed chair body, grafting support pad one end is the external splines shape, installs and reliably fixes at handrail or the inside force -bearing point of rail, with bearing spline coupling, the stopping is inserted the tip and is installed on one side of bearing, and the stopping is inserted the tip and is passed handrail or rail, and when pushing down the stopping and inserting the tip, its lower extreme prong can just fill up the bearing limit. A handrail angle demodulator, simple structure, convenient operation is easy -to -use, encloses angle quick adjustment and reliable location.

Description

A kind of handrail angle demodulator

Technical field

This utility model relates to a kind of handrail angle demodulator.

Background technology

Wheelchair, sofa, basket cot, the handrail of nursing bed, the demand that product uses in different scenes for convenience, usually require that as adjustable-angle.This structural requirement is easy to use, encloses angle and quickly regulates and reliably position.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of handrail angle demodulator.

For solving the problems referred to above, technical solution adopted in the utility model is:

A kind of handrail angle demodulator, including a bearing, grafting support pad and retaining pin, it is characterised in that: described bearing is internal spline shape, is arranged on a chair body;Described grafting support pad one end is external splines shape, is arranged on the force part within handrail or fence and reliably fixes, and couples with a bearing spline；Described retaining pin is arranged on one side of a bearing, and retaining pin passes handrail or fence, and during pressure retaining pin, its lower end prong can just fill up a bearing limit.

Use and have the beneficial effects that produced by technique scheme: described a kind of handrail angle demodulator, simple in construction, easy to operate easy-to-use, enclose angle and quickly regulate and reliably position.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of handrail angle demodulator described in the utility model；

Fig. 2 is one of a kind of handrail angle demodulator example application described in the utility model；

Wherein, 1 is a bearing, and 2 is grafting support pad, and 3 is retaining pin.

Detailed description of the invention

Below in conjunction with accompanying drawing; a kind of handrail angle demodulator described in the utility model is described; purpose is in order to the public is better understood from technology contents described in the utility model; rather than the restriction to described technology contents; in fact; in initiative spirit essence of the present utility model, the improvement to described structure, including to the increase and decrease of corresponding assembly with replace all within this utility model technical scheme required for protection.

As it is shown in figure 1, a kind of handrail angle demodulator, including a bearing 1, grafting support pad 2 and retaining pin 3, a bearing divides solder type and flange-type, and solder type can be directly welded at a chair body；nullFlange-type can be arranged on a chair body with screw or rivet，Two one group of sets are with the use of being preferred，Two set bearings install splined hole to be ensured on the same line，Support pad is directly positioned on the force part within handrail or fence by the grafting support pad with external splines，Reliable fixing，Retaining pin is on the most any a set of limit of two set bearings，By handrail or fence，In another side and the bearing equipped with external splines support pad every ratio time external，The retaining tip is depressed，Its lower end prong can just fill up a bearing limit，The room produced due to handrail or fence propelling spline，Make handrail or fence do not extract move back pin in the case of can not promote，Ensure that the location of handrail or fence is reliable，When needing to regulate angle，First by handrail or jump to spline insert rightabout promote，Interior external splines is made to separate，Forward required angle to，Then tieback，Again fill the retaining tip after making spline tooth to depress.

It is illustrated in figure 2 the example application of a kind of handrail angle demodulator, for regulating the handrail angle of bed, convenient, flexible.

Claims

1. a handrail angle demodulator, including a bearing, grafting support pad and retaining pin, it is characterised in that: described bearing is internal spline shape, is arranged on a chair body;Described grafting support pad one end is external splines shape, is arranged on the force part within handrail or fence and reliably fixes, and couples with a bearing spline；Described retaining pin is arranged on one side of a bearing, and retaining pin passes handrail or fence, and during pressure retaining pin, its lower end prong can just fill up a bearing limit.
