Description

Technical Field

[0001] This utility model relates to the field of mobile DR technology, specifically a mobile folding bedside DR imaging machine. Background Technology

[0002] DR radiography machines are relatively mature radiography equipment. DR radiography machines are mainly divided into fixed types that are in the radiography room and mobile types that are outside the radiography room. Mobile bedside DR radiography machines are portable radiography equipment designed specifically for patients who cannot move, and can quickly complete X-ray imaging at the patient's bedside.

[0003] Existing mobile bedside DR X-ray machines are mainly divided into three types: one is a fixed vertical robotic arm with a horizontal robotic arm that folds via a cylinder; another is a rotating vertical robotic arm with a horizontal robotic arm that can extend and retract vertically on the vertical robotic arm; and the third is a rotating vertical robotic arm with a horizontal robotic arm that folds on the vertical robotic arm. The first type is the traditional type, with a simple structure, low degree of freedom, and low cost. The second type is the most common type of equipment now. The third type is an improvement in recent years. The purpose of folding is mainly to allow for smooth passage through places such as ward doors and elevator doors without collisions due to height. This utility model mainly focuses on improving the mobile folding type.

[0004] For folding cameras, the camera is positioned directly in front of the camera body and at the bottom when folded. During movement, the camera's position cannot be seen. In the event of a collision, the camera will be damaged first, and the repair and replacement costs are relatively high.

[0005] Furthermore, during the use of the equipment, regardless of which of the three types mentioned above, the overall height of the robotic arm after folding exceeds the height of a human body. Since there are many pedestrians in the hospital, the height of the robotic arm will block the view in front when it is moved, and the view can only be seen from the side peripheral vision. The purchase cost of mobile DR equipment is relatively high, and collisions may occur due to obstructed vision during the process of pushing it, which poses a safety hazard to both pedestrians and equipment.

[0006] In addition, in order to facilitate the adaptation to different positions for filming, DR imaging machines have multiple articulated robotic arms. To facilitate free rotation at multiple angles during filming, the articulation points are mostly fixed by damping. However, for mobile DR imaging machines, when walking in a hospital, such as entering and exiting elevators, going up and down slopes, or entering different buildings, there will be bumpy road conditions. The folded robotic arms will shake, which can easily damage the equipment.

[0007] Based on this, the present invention provides a mobile folding bedside DR radiography machine to solve the above problems. Utility Model Content

[0008] In view of the above situation and to overcome the defects of the prior art, this utility model provides a mobile folding bedside DR X-ray machine. This utility model has a novel structure and ingenious design, and effectively solves the technical problems of high cost after the X-ray machine is placed at the front after the robotic arm is folded, excessive height of the robotic arm obstructing the view, loose connection of the robotic arm, and easy damage to the machine body when the machine body is bumpy.

A compression spring is connected below the elastic pressure plate, and a cam pressure block is rotatably installed on the outer side of the elastic pressure plate via an eccentric support shaft. A cam handle is integrally fixed to the cam pressure block, so that when the cam pressure block is rotated, the elastic pressure plate deforms and bends downward, and the pressure teeth and end face teeth cooperate to lock the structure.

Detailed Implementation

[0033] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 6 The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.

[0034] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0035] This utility model is a mobile folding bedside DR imaging machine. Various types of existing mobile folding DR imaging machines have a vertical mechanical arm fixedly or rotatably installed at the front end of the machine body. The length of the vertical mechanical arm is a fixed dimension, and the horizontal mechanical arm slides or rotates on the vertical mechanical arm.

[0036] For folding robotic arms, the camera is folded and placed under the front of the body. During movement, the operator cannot see the position of the camera, which can easily lead to collisions.

[0037] As one embodiment, this utility model includes a body 1, a host 2 for controlling film capture is installed inside the rear of the body 1, the host 2 is connected to a power source, a push rod 3 is fixedly installed at the rear of the body 1 to make it easier to push the body 1, an activity space is provided at the front of the body 1, a telescopic device is rotatably installed at the lower front end of the body 1, a horizontal mechanical arm 4 is hinged to the upper end of the telescopic device, an upper mechanical arm 5 is rotatably installed at the end of the horizontal mechanical arm 4, the upper mechanical arm 5 is C-shaped in general, a film capture camera 6 is rotatably installed inside the upper mechanical arm 5, the film capture camera 6 is connected to the host 2, the host 2, the film capture camera 6, as well as the connection and control methods are all existing technologies, and will not be described in detail here.

[0038] An inclined storage slot 28 is provided in the upper middle of the body 1. When each robotic arm is retracted and folded, the horizontal robotic arm 4 can be tilted and stored in the storage slot 28, reducing the space occupied. After being stored, the camera 6 is stored on top of the body 1, and the operator can ensure the position of the camera 6. Even if a collision occurs, the camera 6 will not be the main damaged part, reducing maintenance and replacement costs.

[0039] The existing vertical robotic arm is taller than the human body, which obstructs the view when moving.

[0040] As one embodiment, the telescopic device includes a vertical robotic arm 7, which is hollow inside. The telescopic device is rotatably mounted below the front end of the body 1. A first telescopic arm 8 is slidably mounted up and down inside the vertical robotic arm 7. The first telescopic arm 8 is hollow inside. A second telescopic arm 9 is slidably mounted inside the first telescopic arm 8. The second telescopic arm 9 is hollow inside. A horizontal robotic arm 4 is hinged to the upper end of the second telescopic arm 9. Threaded holes 10 are provided at the lower ends of both the first telescopic arm 8 and the second telescopic arm 9. A lead screw 11 is threadedly connected to the threaded hole 10 on the first telescopic arm 8. The lead screw 11 is rotatably placed inside the vertical robotic arm 7. A first motor 12 is fixed to the lower end of the lead screw 11. The first motor 12 is connected to the power supply and the host 2. A threaded sleeve 13 is rotatably fitted on the outside of the threaded hole 10 on the first telescopic arm 8. The outside of the threaded sleeve 13 is threadedly connected to the threaded hole 10 on the second telescopic arm 9.

[0041] The lead screw 11 and the threaded sleeve 13 are connected by a keyway. Specifically, a sliding groove is provided on the outer side of the lead screw 11, and a flat key is fixed on the inner wall of the threaded sleeve 13. The flat key is slidably engaged in the sliding groove.

[0042] The vertical robotic arm 7 and the first telescopic arm 8 are connected by a keyway. Specifically, a sliding groove is provided on the inner wall of the vertical robotic arm 7, and a flat key is fixed on the outer side of the first telescopic arm 8. The flat key slides and engages in the sliding groove.

[0043] The first telescopic arm 8 and the second telescopic arm 9 are connected by a keyway. Specifically, a sliding groove is provided on the inner wall of the first telescopic arm 8, and a flat key is fixed on the outer side of the second telescopic arm 9. The flat key is slidably engaged in the sliding groove.

[0044] In this embodiment, when it is necessary to adjust the height position of the camera 6, the first motor 12 is started, which drives the lead screw 11 to rotate. The external thread on the lead screw 11 engages with the internal thread in the threaded hole 10 on the first telescopic arm 8. The sliding groove in the vertical mechanical arm 7 is limited by the flat key on the first telescopic arm 8, so that the first telescopic arm 8 slides as a whole in the vertical mechanical arm 7.

[0045] At the same time, the groove on the lead screw 11 engages with the flat key on the threaded sleeve 13, and the threaded sleeve 13 rotates within the first telescopic arm 8, thereby causing the lead screw 11 to drive the threaded sleeve 13 to rotate. The threaded sleeve 13 is then threadedly connected to the threaded hole 10 on the second telescopic arm 8. The groove within the first telescopic arm 8 and the flat key outside the second telescopic arm 9 limit the movement, thereby allowing the second telescopic arm 9 to slide up and down within the first telescopic arm 8.

[0046] When the telescopic device is fully retracted, the height of the vertical robotic arm 7 is lower than the height of the human eye. At this time, the horizontal robotic arm 4 is tilted and placed in the storage slot 28, so that the vertical robotic arm 7 does not obstruct the view when moving.

[0047] As an example, in order to facilitate the rotation of the lead screw 11, a lower drive chamber 14 is integrally fixed at the lower end of the vertical robotic arm 7. The first motor 12 is fixed inside the lower drive chamber 14 and is connected to the host 2 and the power supply.

[0048] As an example, in order to facilitate the overall rotation of the telescopic device, a drive disc 18 is fixed at the lower end of the lower drive chamber 14. The lower end of the drive disc 18 is connected to a lower extension shaft 15. A large gear 16 is sleeved on the outside of the lower extension shaft 15. A small gear 17 meshes with the large gear 16 on the side. A second motor 19 is coaxially connected to the small gear 17. The second motor 19 is connected to the main unit 2 and the power supply.

[0049] When the rotation of the telescopic device needs to be adjusted, the second motor 19 drives the pinion 17 to rotate, the pinion 17 meshes with the large gear 16 to rotate, thereby achieving a speed reduction function. The large gear 16 drives the lower extension shaft 15 to rotate, the lower extension shaft 15 drives the drive disc 18 to rotate, and the drive disc 18 drives the entire telescopic device to rotate, thus realizing the overall rotation of the telescopic device.

[0050] As an example, to prevent potential damage to the lateral robotic arm 4 and the camera 6 caused by bumps when the machine body 1 moves on the road, a locking device is installed at the hinge of the second telescopic arm 9 and the lateral robotic arm 4, and the same locking device is installed at the hinge of the upper robotic arm 5 and the camera 6.

[0051] The locking device includes a hinge shaft 20 installed at the second telescopic arm 9 and the transverse robotic arm 4, or a hinge shaft 20 installed at the upper robotic arm 5 and the camera 6. Taking the hinge shaft 20 at the second telescopic arm 9 and the transverse robotic arm 4 as an example, the end face of the hinge shaft 20 is provided with end face teeth 21, which are evenly distributed around the end of the hinge shaft 20. An elastic pressure plate 22 is installed on the side plate of the transverse robotic arm 4. The elastic pressure plate 22 is L-shaped. A pressure tooth 23 matching the end face teeth 21 is fixedly installed below the elastic pressure plate 22. A compression spring 24 is connected below the elastic pressure plate 22. The other end of the compression spring 24 is fixed to the side plate of the transverse robotic arm 4. A support shaft 26 is installed on the outside of the elastic pressure plate 22. The support shaft 26 is fixed to the side plate of the transverse robotic arm 4. A cam pressure block 25 is eccentrically mounted on the support shaft 26. A cam handle 27 is integrally fixed on the cam pressure block 25 to facilitate the rotation of the cam pressure block 25.

[0052] In this embodiment, when it is necessary to lock the horizontal robotic arm 4, the cam handle 27 is rotated, and the cam handle 27 drives the cam pressure block 25 to rotate. Due to the self-locking characteristic of the cam itself, the cam handle 27 presses against the elastic pressure plate 22 and bends downward. After the elastic pressure plate 22 is deformed, it drives the lower pressure tooth 23 to engage with the end face tooth 21, so that the horizontal robotic arm 4 is locked.

[0053] Similarly, the operation method is the same when the camera 6 is locked.

[0054] As an example, when the horizontal robotic arm 4 is stored in the storage slot 28, in order to prevent the horizontal robotic arm 4 from shaking excessively in the storage slot 28, a self-locking plug 29 is fixedly installed on the storage slot 28, and a self-locking slot 30 matching the self-locking plug 29 is fixed below the horizontal robotic arm 4. After the self-locking plug 29 and the self-locking slot 30 are engaged, the horizontal robotic arm 4 can be locked into the storage slot 28 on the body 1.

[0055] As one embodiment, the self-locking plug 29 includes a base plate 31 fixedly installed in the storage slot 28. The base plate 31 is generally circular, and a sliding shaft 32 is fixed at the center of the bottom edge 31. The sliding shaft 32 is cylindrical, and an upper conical block 33 with a T-shaped cross section is fixed at the end of the sliding shaft 32. A lower conical block 34 is installed below the upper conical block 33. The lower conical block 34 slides on the sliding shaft 32 and slides between the upper conical block 33 and the base plate 31. The bottom surfaces of the upper conical block 33 and the lower conical block 34 are opposite each other.

[0056] The self-locking slot 30 includes a hollow insertion slot 35. The inner diameter of the insertion slot 35 is slightly larger than the bottom diameter of the upper conical block 33 and the lower conical block 34. Sliding slots 36 are symmetrically opened on both sides inside the insertion slot 35. The sliding slots 36 penetrate the insertion slot 35. A sliding post 37 is slidably installed inside the sliding slot 36. The sliding post 37 is cylindrical in shape. A locking block 38 is fixed at the end of the sliding post 37. The end face of the locking block 38 is inclined and placed inside the insertion slot 35. A sliding spring 39 is sleeved on the sliding post 37.

[0057] In this embodiment, when the horizontal robotic arm 4 is placed in the storage slot 28, the self-locking slot 30 on the horizontal robotic arm 4 contacts the self-locking plug 29 on the storage slot 28. After pressing down, the locking block 38 in the insertion slot 35 is locked between the upper cone block 33 and the lower cone block 34 through the upper cone block 33. The plane of the locking block 38 is attached to the bottom surface of the upper cone block 33 so that it cannot be disengaged, thereby locking the horizontal robotic arm 4 and preventing the horizontal robotic arm 4 from shaking or bumping during movement.

[0058] When it is necessary to remove it, continue to press the horizontal robotic arm 4 downward. The inclined surface of the locking block 38 in the insertion slot 35 is pressed and compressed by the inclined surface of the lower cone block 34 and continues to slide downward. When the locking block 38 is below the lower cone block 34, lift the horizontal robotic arm 4 upward. The plane of the locking block 38 drives the lower cone block 34 to slide upward. When it moves to the bottom surface of the upper cone block 33, the bottom surface of the lower cone block 34 coincides with the bottom surface of the upper cone block 33. The locking block 38 slides out from the inclined surface of the lower cone block 34 through the inclined surface, thus achieving disengagement.

[0059] As an example, a caster wheel 40 is fixed at the lower front end of the body 1 to facilitate movement of the body 1 in different directions. A traveling wheel 41 is fixedly installed at the lower rear of the body 1. The traveling wheel 41 is equipped with a braking device to facilitate movement of the equipment. The traveling wheel 41 can also be connected to a drive motor and then to the host 2 as needed to achieve automatic movement.

[0060] An X-ray film and a flat panel detector are installed at the rear of the machine body 1. The film loading slot 42 can rotate and can hold X-ray films and flat panel detectors.

[0061] As an example, an LCD screen 43 is installed at the rear of the main body 1. The LCD screen 43 is connected to the main unit 2, and the LCD screen 43 has touch points for controlling various functions.

[0062] Working principle of this utility model:

[0063] Before moving, retract the telescopic device, fold the horizontal robotic arm 4 into the storage slot 28, press the horizontal robotic arm 4, and lock the horizontal robotic arm 4 by cooperating with the self-locking slot 30 and the self-locking plug 29, and then move the body 1 to the designated position.

[0064] When the camera 6 needs to work, press down on the horizontal mechanical arm 4 to disengage it through the self-locking slot 30 and the self-locking plug 29. Then, rotate the horizontal mechanical arm 4, the upper mechanical arm 5, and the camera 6 as needed to control the telescopic device to a suitable height. Finally, lock the horizontal mechanical arm 4 and the camera 6 through the locking device.

[0065] The present invention has the following technical effects.

[0066] 1. This utility model has a storage slot on the body, which can be tilted and folded into the storage slot. The folded camera is placed directly above the body, rather than below the front of the body. Even if a collision occurs during the movement, it will not damage the main camera, thus reducing maintenance and replacement costs.

[0067] 2. This utility model adds a first telescopic robotic arm, a second telescopic robotic arm, a threaded sleeve, a lead screw, and other mechanisms to the original vertical robotic arm. By simply rotating the lead screw, the lead screw drives the telescopic device to retract, so that the overall height of the telescopic device and the horizontal robotic arm is lower than the machine body after folding and telescopic, thus avoiding the problem of obstructed vision.

[0068] 3. By incorporating a support shaft, cam pressure block, cam handle, and other structures, this utility model allows the robotic arm to lock in place after it has moved to the appropriate position by simply rotating the cam handle. This effectively prevents the robotic arm from becoming loose.

[0069] 4. By incorporating a storage slot, a self-locking plug, and a self-locking slot, this utility model allows the horizontal robotic arm to be folded and placed in the storage slot. The locking block in the self-locking slot and the upper conical block on the self-locking plug lock together, preventing the horizontal robotic arm from swaying and bumping during movement.
