Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an elastic supporting structure. Background Art

[0002] Currently, breast imaging is performed using a multifunctional scanner, in which the collimator is located parallel to the front end of the detector. The X-ray source then emits X-rays that pass through the scanning cup and the object being measured, and then pass through the collimator into the detector to achieve 3D tomography imaging. Since the object being measured may be larger than the scanning cup, it is necessary to change the position of the scanning cup and the collimator to complete the scanning imaging. Usually, the collimator and the scanning cup are moved to multiple positions for scanning imaging. The collimator is generally connected to the instrument through a rotating mechanism on one side, and when the collimator is rotated to different positions, the other side of the collimator is in a suspended state. If it hovers for a long time, the collimator's support plate is easily deformed, causing the collimator to move, affecting the data results. At the same time, the entire instrument will also have large bumps or vibrations when moving, which will also cause the collimator's support plate to deform.

[0003] In view of this, the present invention provides an elastic support structure to provide braking for the collimator while providing support function for the collimator. Utility Model Content

The supporting and braking mechanisms include a fixed frame, and a spring pin is provided on the fixed frame. The spring pin faces the top side of the fixed frame. A photoelectric switch and a baffle are also provided on the top of the fixed frame.

[0022] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0023] Please refer to Figures 1-6 The present invention proposes an elastic support structure comprising a collimator support plate 2 and at least two support brake mechanisms 4, wherein:

[0024] A collimator 1 is provided on the top of the collimator support plate 2, and one side of the collimator support plate 2 is connected to the rotating mechanism;

[0025] The two supporting and braking mechanisms 4 are respectively arranged at two different workstations at the bottom of the collimator support plate 2. The supporting and braking mechanism 4 includes a fixing frame 44. A spring pin 41 is provided on the fixing frame 44. The spring pin 41 faces the top side of the fixing frame 44. A photoelectric switch 42 and a baffle 43 are also provided on the top of the fixing frame 44. The photoelectric switch 42 is located on the side of the spring pin 41 away from the collimator 1 and is electrically connected to the rotating mechanism. The baffle 43 is located on the side of the photoelectric switch 42 away from the spring pin 41.

[0026] In this embodiment:

[0027] The collimator support plate 2 is used to fix the collimator 1;

[0028] The spring pin 41 is used to support the collimator support plate 2;

[0029] The photoelectric switch 42 is used to control the rotation mechanism to stop;

[0030] The baffle 43 is used to prevent the collimator support plate 2 from moving further;

[0031] In a specific embodiment, the collimator support plate 2 is fixed on the top of the rotating mechanism, and the collimator 1 is fixed on the collimator support plate 2. The rotating mechanism drives the collimator 1 to rotate horizontally 90 degrees. At 0 degrees and 90 degrees, a supporting brake mechanism 4 is respectively provided at the bottom of the collimator support plate 2. The two supporting brake mechanisms 4 are used for support and braking to improve data accuracy. Among them, the spring pin 41 faces the top. When the collimator support plate 2 rotates, the spring pin 41 is first squeezed downward. The elastic force of the spring pin 41 supports the collimator support plate 2, and then passes through the position of the photoelectric switch 42 for braking. After receiving the signal, the photoelectric switch 42 transmits the signal to the rotating mechanism. The rotating mechanism is used to stop the collimator 1 rotating device 3. When the photoelectric switch 42 fails to provide braking information in time due to an unexpected situation, the rotating mechanism continues to drive the collimator support plate 2 to rotate, and then the baffle 43 touches the collimator support plate 2 for forced braking. After braking, the spring pin 41 stops moving downward and continues to provide upward supporting force to the collimator support plate 2 until the collimator support plate 2 leaves the supporting braking mechanism 4 and then restores. The photoelectric switch 42 and the baffle 43 are used to brake, and the collimator support plate 2 can fall on the spring pin 41 for support, which can prevent the collimator support plate 2 from being deformed when the instrument moves or the collimator 1 rotates, thereby affecting the data.

[0032] Furthermore, a transition portion 21 is provided at the bottom of the collimator support plate 2 away from the rotating mechanism. One side of the bottom of the transition portion 21 is an arc surface and contacts the spring pin 41 .

[0033] In a specific embodiment, the transition portion 21 is used to contact the spring pin 41. The entire transition portion 21 is arc-shaped. When the collimator support plate 2 rotates, the spring pin 41 can be pressed down smoothly. At the same time, the spring pin 41 is not easy to hinder the rotation of the collimator support plate 2.

[0034] Furthermore, a stopper 22 is provided at the bottom of the collimator support plate 2 . The stopper 22 is provided on the other side of the transition portion 21 . The stopper 22 is used to block the photoelectric switch 42 .

[0035] In a specific embodiment, the block 22 blocks the light of the photoelectric switch 42. After the light of the photoelectric switch 42 is blocked, a braking signal is provided to stop the rotating device 3 from rotating, thereby performing braking.

[0036] Furthermore, the baffle 43 faces the top of the fixing frame 44 , and one side of the baffle 43 contacts the edge of the collimator support plate 2 .

[0037] In a specific embodiment, the baffle 43 is "L"-shaped and is arranged at the edge of the fixing frame 44. The height of the baffle 43 is greater than the distance between the bottom of the collimator support plate 2 and the top of the fixing frame 44. In the event of an unexpected situation, the baffle 43 performs forced braking to prevent the rotating mechanism from continuing to rotate.

[0038] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
