Description

Technical Field

[0001] The utility model relates to the technical field of oral CT wire ducts, and in particular to a base wire duct installation structure and a floor-standing oral CT. Background Art

[0002] CBCT is the abbreviation of cone beam CT. As the name suggests, it is a cone beam projection computer reconstruction tomography device. Its principle is that the X-ray generator uses a low radiation dose (usually the tube current is about 10 mA) to perform circular DR (digital projection) around the projection object. At present, CBCT has been widely used. Traditional CBCT usually adopts a vertical structure. The top of the equipment column extends out of the bracket, and a rotating arm is suspended under the bracket. The radiation source and detector are located at the two ends of the arm respectively.

[0003] When the equipment is working, the rotating arm rotates above the patient's head. Since the vertical bracket and the rotating arm are far away from the ground, the corresponding wiring trough is also far away from the ground, which makes the wiring arrangement of various circuits inside the traditional CBCT complicated and cumbersome. In addition, the traditional CBCT usually uses a drag chain trough. After a shot is completed, when the CT equipment continues to rotate and shoot, it is easy to cause the problem of tangled wires. Therefore, a base trough installation structure and a floor-standing oral CT are proposed. Utility Model Content

[0004] The utility model aims to solve the problem that the wiring trough of the existing CBCT equipment is far away from the ground and is not convenient for wiring harness arrangement, and the equipment needs to be rotated and reset after rotating for shooting once, which easily causes the wire to be tangled during continuous shooting.

[0005] In order to achieve the above-mentioned invention object, the utility model provides the following technical solutions:

[0006] The base wire trough installation structure and the floor-standing oral CT, including the slewing support, also include:

[0007] A wiring assembly, wherein two wiring assemblies are provided, and the two wiring assemblies are symmetrically arranged on both sides of the top of the slewing support in an arc shape, and can rotate synchronously with the slewing support after the wiring bundle is arranged; and

[0010] As a preferred technical solution of the present application, a cover plate is detachably connected to the top of the arc-shaped frame, and a plurality of positioning holes that cooperate with each other are provided on the surface of the cover plate and the arc-shaped frame.

[0011] As a preferred technical solution of the present application, the wiring assembly also includes a rectangular wire groove arranged in the middle of one side of the arc frame facing the center direction of the swivel support circle, and the rectangular wire groove is connected to the wiring cavity.

[0012] As a preferred technical solution of the present application, both sides of the top of the rectangular wire trough are provided with flanges integrally formed with the inner wall of the arc-shaped frame, and the flanges are in the shape of a trumpet.

[0013] As a preferred technical solution of the present application, the lead assembly includes a wire outlet trough arranged at the bottom of the rectangular wire trough and connected thereto.

[0014] As a preferred technical solution of the present application, the lead assembly also includes a bottom wire protection groove arranged at one end of the rectangular wire groove away from the arc frame, and the side wall of the bottom wire protection groove is provided with four equally spaced arc-shaped notches.

[0015] As a preferred technical solution of the present application, a flange plate is provided in the middle of the outer side of the arc-shaped frame, and the flange plate and the top of the slewing support are provided with mutually matching mounting holes.

[0016] As a preferred technical solution of the present application, both ends of the top of the arc-shaped frame are provided with wire entry grooves connected to the wiring cavity.
