Abstract
The present invention relates to an elbow matching member for the butting of an upper arm. An elbow ball is mutually connected with a lower arm made from hollow plastics by a joint shaft in the elbow matching member. The elbow ball and the lower arm are locked by a graduation fixer in different bending positions. The proximate connection of the lower arm and an upper arm shaft is generated by a casting ring. An upper arm rotary joint is arranged for the adjustable rotation of the lower arm. The present invention suggests that an annular bearing is formed by the upper arm rotary joint in order to cause the elbow matching member to be applied to all upper arm butting length. The graduation fixer is a locking device which is arranged outside the elbow ball and forms an integral body with a part of a rotary connecting member for forming the joint shaft.
Description
The present invention relates to a kind of elbow joint that is used for the upper arm butt joint, in this elbow joint, the elbow ball is connected with the underarm of being made by the plastics of hollow by a joint shaft and can be locked on the different bending positions by a calibration holder, be connected with last arm axle is immediate and produce, and be provided with a upper arm cradle head for adjustable rotation of underarm by a casting ring.
Known elbow joint has the upper arm cradle head of its structure for the arc joint that is made of plane bearing, and for this reason, this known elbow joint only is suitable for limited upper arm butt joint length.For being provided, long butt joint to use a kind of elbow joint that does not have the arc joint.Up to the present, known elbow joint has a kind of calibration holder, and these elbow joints are entrenched on the groove that is provided with on the neighboring of elbow ball.
Task of the present invention is a kind of foregoing elbow joint of design, and this elbow joint is suitable for all upper arm butt joint length.
This task so solves according to the present invention, and promptly this upper arm cradle head is made of a kind of bearer ring, and the calibration holder be a kind of be placed in the elbow ball outer, with form being rotationally connected of part joint shaft and constitute the locker of one.
What conform with purpose is, this upper arm cradle head comprises a support ring that install and that fixedly connected with this elbow ball in the elbow ball, this support ring has a diaphragm rings, this diaphragm rings is fixed by a brake hoop, this brake hoop is fixedlyed connected with the casting ring, and this casting ring is with respect to rotatable 180 ° of support ring.
Measure of the present invention can provide to patient and connect length arbitrarily, till only utilizing a cradle head.Therefore, can obtain being used for docking arbitrarily the desired space of length by support ring as the plane bearing that the upper arm cradle head replaces using up to now.Pacify the geometry that the locker of joining has guaranteed long butt joint length by this outside, do not require structural coupling for different butt joint length.
Other feature is the content of dependent claims, is further elaborated by means of an embodiment below these features and the advantage of the present invention.
Embodiments of the invention have been represented in the accompanying drawings as example.
The side view of an elbow joint of Fig. 1 and part longitudinal sectional drawing;
Fig. 2 rotates 90 ° longitudinal sectional view according to Fig. 1;
The partial enlarged drawing of Fig. 3 Fig. 2;
The structure of Fig. 4 locker take expression apart;
Fig. 5 is hinged on the vertical view of the locker on the flat board of joint;
Fig. 6 is according to the expression of taking apart of another structure of the locker of Fig. 5;
The vertical view of a brake hoop of Fig. 7;
Fig. 8 is according to the profile of the A-A line of Fig. 7.
Form by the underarm 1 that a hollow working of plastics constitutes substantially at the elbow joint shown in Fig. 1 and 2, end bearing an elbow ball 2 that can rotate around joint shaft 3 on this underarm 1, can the elbow ball be locked on the different bending positions by a calibration holder.Be provided with a casting ring 4 in order the most closely to be connected with a last armed lever of not representing, this casting ring 4 is parts that the upper arm cradle head is used for the underarm 1 of scalable rotation.When underarm 1 freely swung, this extension was limited by a preceding backstop that is made of the perlon silk, and this backstop is fixed on the elbow ball 2 on the one hand, is fixed on the other hand on the underarm 1.
The upper arm cradle head comprises that is installed in a support ring 7 in the elbow ball 2 and that use screw 6 to fixedly connected with the elbow ball, and this support ring 7 has a diaphragm rings 8, and this diaphragm rings 8 and a brake hoop 9 are chimeric, and this brake hoop 9 is fixedlyed connected with casting ring 4 by screw 10.Brake hoop 9 constitutes a seam, and is installed on the diaphragm rings 8.The ring edge 11 towards the elbow ball of brake hoop 9 has a chamfering 12 that surpasses 180 ° of circumference angles, this chamfering 12 relatively, and for example brake component 13 of being made by non-ferrous metal bolt 14 by from the outside can be approaching is radially clamped.Can the brake force of regulating action on brake hoop 9 by regulating bolt 14.
Flanged ring 15 of support ring 7 usefulness is overlapped on the elbow ring 5, and flanged ring 15 upper supports casting ring 4 (asking for an interview Fig. 2 and 3), and this casting ring 4 surpasses the chamfering 12 of brake hoop 9, thereby can rotate 180 °.
Outside elbow ball 2, form a calibration holder that is locker and a rotating connector that forms a joint shaft 3 constitute an integral body.This integral body is together with being rotatably supported on the joint flat board 16 that is disposed, as shown in Figure 5 at the housing on the joint axle journal 19 23.According to the expression of taking apart of Fig. 4, housing 23 and joint flat board 16 are connected between baffle plate 24, compression spring 25, index dial 26 and the switch spring 27 (asking for an interview Fig. 6).
A slay 28 has been installed on housing 23, and slay 28 usefulness flanges 29 close housing 23, and slay 28 comprises an effect that can overcome compression spring 30 and mobile wedge 31, and wedge 31 is handled ratchet pawls 32, and ratchet pawl 32 is by compression spring 33 effects.For wedge 31 has disposed switch spring 27.
Wedge 31 has a headless screw 34 in one end thereof, and this headless screw 34 passes flange 29 and the supporting 29a of the slay 28 that is shaped thereon.On this headless screw 34, screwing, fixing a handle 36 that is used for the manual manipulation locker at the free end of this drag-line 35 at the drag-line shown in Fig. 1 and 2 35.
36 locker is unclamped by pulling handle; Elbow ball 2 can freely swing with respect to underarm 1 between joint flat board 16.Again pulling handle 36 can make elbow ball 2 be fixed on desirable bending position, for example, 18 indexing positions can be set.
