Description

Technical Field

[0001] This utility model relates to the field of radiotherapy quality control and testing equipment, and in particular to a reference detector bracket for a water tank scanning device. Background Technology

[0002] The reference detector in the water tank scanning device is a device used to provide a reference signal or reference data. It plays an important role in calibration and comparison during the water tank scanning process. The bracket is a component used to fix and support the reference detector. It helps to ensure the positional accuracy and stability of the reference detector, thereby improving the measurement accuracy of the water tank scanning device.

[0003] Existing reference detector brackets require a different bracket adapter for each model, which is inconvenient to assemble and takes up the user's time. Since they are fixed by plastic screws, the detector will shake during scanning, which will eventually lead to distorted acquisition results. At the same time, most brackets are unidirectional, which means that they only support one or more fixed directions, limiting the range of use of the brackets.

[0004] Therefore, most of the existing detectors use compatible brackets, which are inconvenient to assemble and take up the user's time. In addition, the use of plastic screws for fixing can cause the detector to be unstable and affect the acquisition effect. At the same time, the bracket is fixed in one direction, which limits its scope of use. A reference detector bracket for a water tank scanning device can be designed, which can be flexibly adjusted according to the detector, thereby improving the applicability and scope of use of the bracket. Utility Model Content

[0005] To overcome the problems of existing detectors, which mostly use compatible brackets, are inconvenient to assemble and take up users' time, and are fixed with plastic screws, which can cause the detector to be unstable and affect the acquisition effect, and the bracket is fixed in one direction, which limits its application range, a reference detector bracket for a water tank scanning device is proposed.

[0006] The technical solution of this utility model is as follows: a reference detector bracket for a water tank scanning device, including a G-type base; a rotating base is provided above the G-type base, and a mounting bracket is provided above the rotating base. A limiting module is sleeved between the rotating base and the mounting bracket. A lead screw is vertically threaded to the bottom of the G-type base, and an adjusting block is fixedly connected to the upper end of the lead screw. A through hole is opened on the mounting bracket, and a mounting stud is provided above the through hole. The mounting stud passes through the mounting bracket and is threadedly connected to it. The limiting module includes a limiting ring sleeve, and four sets of rectangular sleeves are fixedly connected around the limiting ring sleeve. A rectangular column is sleeved inside the rectangular sleeve. An arc-shaped limiting plate is fixedly connected to the end of the rectangular column away from the rectangular sleeve, and a limiting pad is fixedly connected to the side of the arc-shaped limiting plate away from the rectangular column.

[0007] Furthermore, a nut is installed on the threaded outer wall of the lead screw.

[0008] Furthermore, a snap-fit ​​post is fixed to the upper end of the G-type base.

[0009] Furthermore, a snap-fit ​​groove is provided in the middle of the lower part of the rotating base, and the snap-fit ​​post is positioned and connected to the rotating base through the snap-fit ​​groove.

[0010] Furthermore, a fixing stud is threadedly connected to the connection between the rotating base and the snap-fit ​​post, and a first knob is fixedly connected to one end of the fixing stud.

[0011] Furthermore, a connecting post is fixed to the lower end of the mounting bracket, a rotating ball is fixed to the lower end of the connecting post, and a second knob is fixed to the upper end of the mounting stud.

[0012] Furthermore, locating pins are symmetrically provided on both sides of the connection between the rectangular column and the rectangular sleeve, and multiple sets of locating holes are symmetrically opened on both sides of the rectangular column. The locating pins pass through the rectangular sleeve and are positioned and connected to the rectangular column through the locating holes.

[0013] The beneficial effects of this utility model are as follows: The mounting bracket is securely positioned by being fixed to the water tank guide rail via a G-type base. Combined with the rotation adjustment of the rotating ball below the mounting bracket along the rotating base, and the movement adjustment of the limit module, the reference detector can be precisely and flexibly adjusted to a suitable position according to the specific requirements of water tank scanning. This effectively prevents the detector from obstructing the scanning probe or other key components, ensuring a smooth scanning process and improving the accuracy of measurement results. The bracket structure allows the detector to pass through and be fixed within the mounting bracket, providing suitable installation and adjustment methods for reference detectors of different models and sizes. This significantly improves the applicability of the bracket and enhances the product's versatility. Furthermore, the limit module limits the adjusted mounting bracket, effectively preventing detector shaking during measurement, reducing measurement errors caused by shaking, and ensuring the reliability and stability of the measurement data.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-5 As shown, this utility model provides an embodiment: a reference detector bracket for a water tank scanning device, including a G-type base 1; a rotating base 2 is provided above the G-type base 1, and a mounting bracket 3 is provided above the rotating base 2. A limiting module is sleeved between the rotating base 2 and the mounting bracket 3. A lead screw 101 is vertically threaded to the bottom of the G-type base 1, and an adjusting block 102 is fixedly connected to the upper end of the lead screw 101. A through hole 303 is provided on the mounting bracket 3, and a mounting stud 304 is provided above the through hole 303. The mounting stud 304 passes through the mounting bracket 3 and is threadedly connected to it. The limiting module includes a limiting ring 401, and four sets of rectangular sleeves 4 are fixedly connected around the limiting ring 401. 02. A rectangular column 403 is fitted inside the rectangular sleeve 402. An arc-shaped limiting plate 406 is fixed to the end of the rectangular column 403 away from the rectangular sleeve 402. A limiting pad 407 is fixed to the side of the arc-shaped limiting plate 406 away from the rectangular column 403. First, the G-type base 1 is snapped and fixed along the water tank guide rail. Then, the detector is passed through the mounting bracket 3 and fixed. Then, according to the measurement requirements, the rotating ball 302 under the mounting bracket 3 is rotated and adjusted along the rotating base 2 to change the measurement direction of the detector. Finally, the limiting module is moved and adjusted to limit the mounting bracket 3 after adjustment to prevent the detector from shaking during the measurement process.

[0022] Please see Figure 2 In this embodiment, a nut 103 is threaded on the outer wall of the lead screw 101, and a snap-fit ​​post 104 is fixedly connected to the upper end of the G-type base 1. The G-type base 1 is snapped along the water tank guide rail. Then, the lead screw 101 is turned, and the adjusting block 102 moves upward until it touches the lower end of the water tank guide rail, and then the nut 103 is tightened to fix it.

[0023] Please see Figures 2-3In this embodiment, a snap-fit ​​groove 201 is provided in the middle of the lower part of the rotating base 2. The snap-fit ​​post 104 is positioned and connected to the rotating base 2 through the snap-fit ​​groove 201. A fixing stud 202 is threadedly connected to the connection between the rotating base 2 and the snap-fit ​​post 104. A first knob 203 is fixedly connected to one end of the fixing stud 202. After the entire bracket has been used for a period of time, the first knob 203 is rotated, and the fixing stud 202 is moved out along the axial direction, so that the G-type base 1 and the rotating base 2 can be separated and replaced to avoid long-term use and affect the overall stability.

[0024] Please see Figure 4 In this embodiment, a connecting post 301 is fixedly connected to the lower end of the mounting bracket 3, and a rotating ball 302 is fixedly connected to the lower end of the connecting post 301. A second knob 305 is fixedly connected to the upper end of the mounting stud 304. The detector is picked up and passed through the through hole 303 through the mounting bracket 3. Then the second knob 305 is rotated so that the mounting stud 304 rotates downward until the lower end of the mounting stud 304 abuts against the detector and fixes it.

[0025] Please see Figure 5 In this embodiment, locating pins 404 are symmetrically provided on both sides of the connection between the rectangular column 403 and the rectangular sleeve 402. Multiple sets of locating holes 405 are symmetrically opened on both sides of the rectangular column 403. The locating pins 404 pass through the rectangular sleeve 402 and are positioned and connected to the rectangular column 403 through the locating holes 405. By adjusting the locating pins 404, the rectangular column 403 is extended and retracted along the rectangular sleeve 402 until the arc-shaped limiting plate 406 continuously approaches the connecting column 301, so that the limiting soft pad 407 fits against the outer wall of the connecting column 301.

[0026] The G-type base 1 is snapped onto the water tank guide rail. Then, the screw 101 is turned, and the adjusting block 102 moves upward until it abuts against the lower end of the water tank guide rail. The nut 103 is then tightened to secure it. Next, the detector is picked up and passed through the through hole 303 into the mounting bracket 3. The second knob 305 is then turned, causing the mounting stud 304 to rotate downwards until its lower end abuts against the detector, securing it. After assembly, the mounting bracket 3 is adjusted according to measurement requirements, causing the rotating ball 302 to rotate along the rotating base 2 to change the detector's measurement direction. Once the adjustment is correct, the rectangular column 403 is adjusted along the rectangular sleeve 402 by the positioning pin 404 until the arc-shaped limiting plate 406 continuously approaches the connecting column 301, causing the limiting pad 4... 07. After confirming that the outer wall of the connecting column 301 is aligned correctly, pick up the positioning pin 404 and pass it through the rectangular sleeve 402 and through the positioning hole 405 to position and connect it with the rectangular column 403. This limits the adjustment of the mounting bracket 3 from multiple directions to prevent the detector from shaking during the measurement process. After the entire bracket has been used for a period of time, turn the first knob 203 to move the fixing stud 202 out axially, so that the G-type base 1 and the rotating base 2 can be separated and replaced to avoid long-term use affecting the overall stability. Then pick up the G-type base 1 and the rotating base 2 so that the snap-fit ​​column 104 is positioned and connected to the rotating base 2 through the snap-fit ​​groove 201. Then pick up the fixing stud 202, rotate it and insert it into the snap-fit ​​column 104 and the rotating base 2, and connect it with the thread, so that it can be used again.
