Description

Technical Field

[0001] The utility model belongs to the technical field of a DR system ball tube column, and in particular relates to a 360-degree forward and reverse rotation device for a DR system ball tube column to prevent twisting. Background Art

[0002] The double-column DR system (X-ray imaging system) is currently the most widely used type of DR system in the industry. And as we all know, the bottom of the tube column used to support the tube in this type of DR system is usually designed with a rotating device installed to facilitate the rotation of the tube, and the rotation of the tube can bring many conveniences.

[0003] The wires of the existing DR system tubes are usually routed from the inside of the tube column and are designed to pass through the wiring holes inside the rotating device. In order to prevent the wires from being cut, a matching stopper is provided on the outer periphery of the rotating disk of the rotating device relative to the base of the tube column. However, there are the following defects: 1. Due to the existence of the stopper, the turntable cannot truly complete a full 360-degree rotation regardless of whether it rotates forward or reverse; 2. If the stopper is thinned to reduce this deviation, the thinner the stopper is designed, the easier it is to collide and be damaged after multiple rotations, and eventually lose its stopper function. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a 360-degree forward and reverse rotation device for a DR system ball tube column to prevent twisting of wires. The technical solution adopted is as follows:

[0005] A device for rotating a ball tube column of a DR system for preventing twisting of wires in a clockwise and counterclockwise direction of 360 degrees, comprising a sliding seat installed on the ball tube column, a connecting seat for connecting a telescopic tube is arranged on the front side of the sliding seat, a baffle is arranged on a side of the connecting seat contacting with the telescopic tube, and a ball tube is connected to one side of the telescopic tube;

[0006] An inner cylinder is provided on the side of the ball tube facing the telescopic cylinder, an insertion hole for inserting the inner cylinder is provided in the telescopic cylinder, a rotating groove is provided inside the insertion hole, a moving groove is provided inside the insertion hole, a protrusion for sliding in the moving groove is provided at one end of the inner cylinder, a positioning pin is provided at the other end of the inner cylinder close to the ball tube, and a telescopic controller for controlling the telescopic movement of the positioning pin is provided on the inner side of the inner cylinder.

[0007] Furthermore, a base frame for mounting the telescopic rod is provided inside the telescopic controller, a card plate is installed at the front end of the telescopic rod, and an oblique groove in contact with the card plate is provided on one side of the positioning pin facing the card plate.

[0008] Furthermore, a telescopic spring is provided at one end of the base frame and below the positioning pin, which can make the positioning pin rebound and reset. When the positioning pin passes through the positioning groove, the positioning pin bounces up and engages with the positioning groove, which can play a role in fixing the ball tube.

[0009] Furthermore, a controller connected to a rotation unlocking button in the ball tube is provided inside the base frame, and the operation of the telescopic rod can be controlled by pressing the rotation unlocking button, and the controller adopts an electric push rod controller.

[0010] Furthermore, after the inner tube is inserted into the insertion hole in the telescopic tube, the protrusion in the inner tube is located in the movable groove, and the positioning pin is located in the rotation groove in the insertion hole. Furthermore, the rotation groove is a spiral groove, which can enable the positioning pin to rotate exactly 360 degrees in the rotation groove, and a positioning groove is provided every 90 degrees in the rotation groove.

[0011] Furthermore, a sleeve is provided at one end of the ball tube and located outside the inner tube, and one end of the sleeve is in contact with a baffle in the connecting seat.

[0012] Furthermore, a plurality of guide posts inserted into the interior of the telescopic cylinder are provided on the front side of the connecting seat.

[0013] Furthermore, the side of the telescopic cylinder facing the connecting seat is provided with two inner grooves, and a tension spring connected to the connecting seat is provided in the inner groove.

[0014] Furthermore, a threading hole for threading is provided inside the connecting seat, the telescopic tube and the inner tube, and the cable passes through the threading hole and is connected to the ball tube.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The utility model can limit the ball tube to rotate 360 ​​degrees in both directions by arranging the rotating groove. When the cable passes through the connecting seat, the telescopic tube and the inner tube, no twisted wire will be generated, thereby ensuring the safe use of the cable. The rotating groove is a spiral structure. Since the two uppermost positioning grooves are on the same collinear line, the ball tube can be completely rotated 360 degrees. The telescopic tube and the connecting seat are arranged in a movable connection, and a baffle for resisting the sleeve is arranged on the side of the connecting seat, so that no matter how the ball tube rotates, the origin position always remains unchanged, and can be accurately aligned with the digital tablet. Moreover, by adding the positioning groove, precise positioning less than 90 degrees can be achieved.

[0017] Compared with the prior art, no baffle is provided, and there is no need to worry about the baffle losing its blocking function. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be described clearly and completely below. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0032] As attached Figure 1-11 shown.

[0033] A 360-degree forward and reverse rotation device for a ball tube column of a DR system to prevent twisting of wires, comprising a sliding seat 2 installed on a ball tube column 1, the sliding seat 2 can be raised and lowered in the ball tube column 1, a connecting seat 3, a telescopic cylinder 4 and a ball tube 5 are sequentially installed on one side of the sliding seat 2, the connecting seat 3 and the telescopic cylinder 4 are movably connected, 2-4 guide columns 32 inserted into the telescopic cylinder 4 are arranged on the front side of the connecting seat 3, the telescopic cylinder 4 cannot rotate under the action of the guide columns 32, and can only move along the guide columns 32.

[0034] The telescopic cylinder 4 and the ball tube 5 are also movably connected. An inner cylinder 51 inserted into the telescopic cylinder 4 is provided on one side of the ball tube 5, and an insertion hole 41 for inserting the inner cylinder 51 is provided at a corresponding position of the telescopic cylinder 4. A rotating groove 42 and a movable groove 44 are provided in the insertion hole 41. A protrusion for sliding in the movable groove 44 is provided at one end of the inner cylinder 51, and a positioning pin 7 for rotating and sliding in the rotating groove 42 is provided at the other end of the inner cylinder 51. A telescopic controller 8 for controlling the telescopic movement of the positioning pin 7 is also provided on the inner side of the inner cylinder 51.

[0035] A base frame 81 for mounting a telescopic rod 82 is provided inside the telescopic controller 8, a card plate 83 is installed at the front end of the telescopic rod 82, an inclined groove 71 for contacting the card plate 83 is provided on the side of the positioning pin 7 facing the card plate 83, and a telescopic spring 84 is provided at one end of the base frame 81 and below the positioning pin 7.

[0036] A rotating lock button 52 connected to the controller 85 in the telescopic controller 8 is provided on the front side of the ball tube 5. When the rotating lock button 52 is pressed, the telescopic rod 82 can be controlled to extend, thereby pushing the clamping plate 83 forward, and under the action of the inclined groove 71, the positioning pin 7 is lowered. When the rotating lock button 52 is released, the telescopic rod 82 retracts, and the positioning pin 7 rebounds under the action of the telescopic spring 84.

[0037] There are five positioning grooves 43 . The rotating groove 42 is a spiral groove. A positioning groove 43 is provided every 90 degrees in the rotating groove 42 . The two uppermost positioning grooves 43 are on the same collinear line, so that the positioning pin 7 can rotate exactly 360 degrees in the rotating groove 42 .

[0038] When the ball tube 5 needs to be rotated, the rotation lock button 52 is pressed, the positioning pin 7 drops and disengages from the positioning slot 43 in the rotation slot 42, and the ball tube 5 can be rotated at this time. When the rotation unlock button 52 is released, the telescopic rod 82 retracts, and the positioning pin 7 rebounds under the action of the telescopic spring 84. When the ball tube 5 rotates every 90 degrees, the positioning pin 7 will bounce up again and be inserted into the positioning slot 43 at another position. If the ball tube 5 needs to be rotated more than 90 degrees at one time, it can be done while keeping the rotation unlock button 52 pressed.

[0039] Under the action of the guide column 32, the telescopic cylinder 4 cannot rotate and can only move forward and backward. Therefore, when the ball tube 5 rotates, under the action of the positioning pin 7 and the rotation groove 42, a force is given to the ball tube 5 to move forward and backward. Since the rear side of the ball tube 5 is installed with a sleeve 6 in contact with the baffle 31, the ball tube 5 will not move during rotation, but the telescopic cylinder 4 will move forward and backward. As the ball tube 5 rotates, when the positioning pin 7 is at different positions of the rotation groove 42, the distance between the telescopic cylinder 4 and the connecting seat 3 will change.

[0040] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
