Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the disclosed embodiments are merely exemplary of the invention, and are not intended to limit the invention to the precise embodiments disclosed. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an arm traction frame, comprising a support column 2, a cross beam 8, a cross sliding sleeve 7, a hook device 10 and an arm connecting frame 6, wherein the support column 2 has two outer frames 3 mounted at the lower ends thereof, the cross beam 8 is fixedly mounted between the upper ends of the two support columns 2 through a connecting member, the cross sliding sleeve 7 is movably sleeved outside the middle end of the cross beam 8, the cross sliding sleeve 7 slides on the cross beam 8, the traction fixing point can be changed according to the position of a patient, the lower end of the cross sliding sleeve 7 is hooked with the hook device 10 with an upper hook 12 and a lower hook 9 movably inserted therein respectively at the upper end and the lower end thereof, the arm connecting frame 6 can rotate in multiple ranges relative to the traction fixing point of the cross sliding sleeve 7 through the rotation of the upper hook 12 and the lower hook 9 without affecting the movement of the patient, the upper hook 12 is hung on the lower end of the cross sliding sleeve 7, the lower hook 12 is rotatably mounted between the lower hook 9 and the upper hook 11, the extension capability of the spring 11 can be prevented from excessive force applied when the arm is pulled by the arm, the lower end of the cross sliding sleeve 9 is inserted into the cross sliding sleeve 7, the cross sliding sleeve 6, the cross sliding sleeve 5, the upper end of the arm connecting frame is inserted into the cross sliding sleeve 5, the cross sliding sleeve 5 is connected with the cross sliding sleeve 5, couple 9 and last couple 12 all rotate relative couple ware 10 on the horizontal direction down, arm link 6 and couple 9 relative pivoted direction and couple 9 and last couple 12 relative couple ware 10 pivoted direction intercrossing down, improve holistic flexibility, all be equipped with the graduation apparatus on support column 2 and the crossbeam 8, can be respectively accurate instruction crossbeam 8 and support column 2's position and displacement through the graduation apparatus on support column 2 and the crossbeam 8.
