In a preferred embodiment, the buffer assembly 50 is disposed at least at one end of the length direction of the boom assembly 10, so as to ensure that the wire set 40 passing through the second passage 112 can pass through the next second passage 112 via the buffer assembly 50, thereby ensuring that the wire set 40 is not piled up or even caught in the entire balance arm.
Specifically, in the present embodiment, as shown in fig. 12 and 13, the buffer assembly 50 includes a support member 51 installed at the hinge of the rotary support member 12 and the housing 11, a buffer member 52 sleeved on the side wall of the support member 51, and a carrier member 53 sleeved on the outer wall of the buffer member 52, wherein the buffer member 52 is formed in a ring-shaped structure sleeved on the sleeve 511 and has elasticity, for example, a rubber ring may be used, the carrier member 53 is formed in a ring-shaped structure, sleeved on the outer wall of the buffer member 52 and rotatably connected to the buffer member 52, and the wire set 40 is attached to the outer wall of the carrier member 53. When the rotating arm assembly 10 causes the wire set 40 to be pulled, the wire set 40 moves toward the direction approaching the support member 51, so that the inner wall of the bearing member 53 can abut against the buffer member 52 to press the buffer member 52.
More specifically, in the present embodiment, as shown in fig. 13, the supporting member 51 includes a sleeve 511 and limiting portions 512 provided at both ends of the sleeve 511, the sleeve 511 is formed in a tubular structure, the limiting portions 512 are provided at both ends of the sleeve 511 in the axial direction so that the carrier 53 and the buffer 52 are both fixed between the two limiting portions 512, the limiting portions 512 are formed in a plate-like structure perpendicular to the axial direction of the sleeve 511, and in a preferred embodiment, edges of the limiting portions 512 protrude out of the outer wall of the carrier 53, so that displacement of the wire set 40 in the axial direction of the sleeve 511 can be limited, and the wire set 40 can be ensured to be in contact with the buffer assembly 50, thereby ensuring reliability and effectiveness of the buffer action of the wire set 40 by the buffer assembly 50.
In this embodiment, as shown in fig. 1 to 7, the balance arm further includes a horizontal rotating arm 20, the horizontal rotating arm 20 is disposed between the base 60 and the rotating arm assembly 10, and the horizontal rotating arm 20 can swing in a horizontal direction with the base 60 as an axis to adjust the position of the ray machine 70 in the horizontal direction. The hinge position of the horizontal boom 20 and the boom assembly 10 is provided with an adjustment assembly 30 to ensure that the boom assembly 10 can be fixed at a desired angle relative to the horizontal boom 20.
According to the balance arm of the X-ray machine, the rotating arm assembly utilizes the motion principle of the parallelogram mechanism and is matched with the adjusting assembly to control the displacement of one side of the parallelogram mechanism, so that the movement of the rotating support piece is prevented, the effect of balancing the weight of the X-ray machine is achieved, the shape of the parallelogram is ensured not to be changed easily, the balance arm is fixedly kept in an unfolded or folded posture, the X-ray machine can stay at any position, and the X-ray machine has the advantages of stable support and reliable fixation;
Secondly, a first channel and a second channel are arranged in the shell, so that the adjusting component and the wire group are separated, clamping of the wire group caused by compression of the elastic piece when the rotating arm component rotates is avoided, even the wire group is wound on the adjusting component, and the fact that the ray machine can be fixed at a required position is ensured;
In addition, realize when rotating the rocking arm subassembly and leading to the group to be pulled through setting up buffer assembly, buffer assembly is extruded by the group and produces the deformation, because buffer assembly has elasticity, when pulling the power and weakening, resumes elastic buffer assembly and can prop up the group for the group former way that produces the displacement returns, thereby avoid leading to the group to collect, the accumulative condition because of rotating the rocking arm subassembly many times, and then solved and pulled the problem that the balance arm that leads to the group not enough to be long because of the group can't rotate to limit rotation angle.
It should be noted that the foregoing embodiments are merely illustrative embodiments of the present application, and not restrictive, and the scope of the application is not limited to the embodiments, and although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that any modification, variation or substitution of some of the technical features of the embodiments described in the foregoing embodiments may be easily contemplated within the scope of the present application, and the spirit and scope of the technical solutions of the embodiments do not depart from the spirit and scope of the embodiments of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
