Description

Technical Field

[0001] This application relates to the field of testing auxiliary equipment technology, specifically a portable XRF scanning stand. Background Technology

[0002] Portable XRF (X-ray Fluorescence) analyzers are rapid, non-destructive testing devices based on the principle of X-ray fluorescence. They are widely used in environmental monitoring, soil pollution analysis, metal material composition detection, mineral element determination, and waste recycling analysis. These devices can perform real-time detection of multiple elements in solid, powder, or liquid samples without sample pretreatment. They are portable, accurate, and efficient, making them particularly suitable for field environments or on-site testing tasks.

[0003] In actual testing, operators usually need to hold a portable XRF analyzer for a long time to scan the target sample. This can easily cause operator fatigue and may also lead to measurement data errors due to hand tremors. In order to ensure the stability and safety of the test, a support or fixing device is usually used to position the analyzer.

[0004] For example, the existing patent with publication number CN220508834U provides a portable XRF analyzer fixing device, which includes a base, a vertical pole, a horizontal bar and a clamping mechanism. This patent solves the technical problems of low working efficiency and high radiation damage to the human body when portable XRF analyzers are used to detect samples.

[0005] However, in practical use, the aforementioned device, with its integrated base and upright, requires a significant amount of space and is inconvenient to carry. Furthermore, the base uses casters for movement and support, which are unreliable in uneven environments, limiting its mobility. Therefore, it is necessary to provide a portable XRF scanning stand to address these issues.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

The vertical rod is fitted onto the upper end of the main rod; A horizontal bar, which is mounted on a vertical bar; A clamp, mounted at the end of a crossbar, is used to hold a portable XRF scanner.

[0009] Furthermore, the clamp includes a fixed clamp and a movable clamp. One side of the movable clamp is rotatably connected to the fixed clamp via a rotating shaft. A stud that passes through the movable clamp is fixedly connected to the fixed clamp. An adjusting head is threaded onto the outer end of the stud, and a spring is sleeved on the middle of the stud.

[0010] Furthermore, an angle adjustment mechanism is installed between the crossbar and the clamp. The angle adjustment mechanism includes a housing, and a worm gear and a worm are rotatably connected inside the housing. One end of the worm extends out of the housing and is fixedly connected to a knob. A rotating shaft is coaxially fixed at the center of the worm gear. The rotating shaft extends out of the housing and is fixedly connected to the fixed jaw.

[0011] Furthermore, the upper end of the main rod is provided with an external thread head, and the outer end of the vertical rod is fixedly sleeved with a screw cap.

[0012] Furthermore, the lower end of the screw cap extends into the interior of the main rod.

[0013] Furthermore, an adjusting sleeve is installed between the vertical rod and the horizontal rod. The adjusting sleeve includes two sleeves, which are fixedly connected perpendicularly to each other. The horizontal rod passes through the horizontally arranged sleeve, and the vertical rod passes through the vertically arranged sleeve. An adjusting screw is fitted onto the outer end of each of the two sleeves, and the two adjusting screws abut against the vertical rod and the horizontal rod, respectively.

[0014] Furthermore, the support foot and the sleeve are connected by a threaded connection.

[0015] The beneficial effects of this application are as follows: The portable XRF scanning frame provided by this application reduces the storage volume of the scanning frame through the foldable main rod and sleeve rod structure, making it easy to carry and store when going out; the combination design of support feet and pulleys ensures flexible movement on flat ground, and the retractable support foot structure ensures stable support on uneven ground.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] like Figure 1-4 As shown, this application provides a portable XRF scanning stand for stable support of portable X-ray equipment, facilitating medical personnel to complete imaging operations quickly and safely.

[0021] The main support structure of the scanning frame includes a main rod 1. Three sleeve rods 2 are connected to the outside of the main rod 1 by hinges. The three sleeve rods 2 are evenly distributed in the circumference and together form a triangular support structure. This design improves the stability of the equipment during movement and use.

[0022] The lower end of each sleeve rod 2 is rotatably connected to a sliding collar (not shown in the figure). The sliding collar is slidably connected to the main rod 1. By pushing and pulling the sliding collar on the main rod 1, the support structure can be quickly unfolded and retracted. After being retracted, the overall structure is compact and easy to move and store in the testing site.

[0023] The support foot 3 is threaded to the lower end of the sleeve rod 2 and is designed to be detachable. The bottom of the support foot 3 is fitted with an anti-slip rubber pad, which can effectively enhance the anti-slip ability of the equipment on the ground and prevent accidental movement.

[0024] A moving mechanism 4 is installed on the outside of the support foot 3. The moving mechanism 4 includes a locking rod 41, a pulley 42, and two locking sleeves 43. The upper end of the locking rod 41 is rotatably connected to the support foot 3 through a pin. The pulley 42 is a self-locking universal wheel, which can quickly lock the wheel when shooting is required to ensure the stability of the equipment. The two locking sleeves 43 are fixed on the upper and lower sides of the support foot 3 respectively. When the locking rod 41 rotates to the preset position, it can be locked with the locking sleeve 43 to ensure safety in the moving state.

[0025] The lever 41 can rotate between the extended position and the retracted position. When the lever 41 is in the extended position, it engages with the lower sleeve 43 and the pulley 42 touches the ground. When the lever 41 is in the retracted position, it engages with the upper sleeve 43 and the support foot 3 is off the ground.

[0026] A vertical rod 5 is sleeved on the upper end of the main rod 1. The upper end of the main rod 1 is machined with external threads. A screw cap 10 is fixedly sleeved on the outer end of the vertical rod 5. The screw cap 10 is threadedly sleeved with the upper end of the main rod 1. The lower end of the vertical rod 5 extends into the main rod 1. During installation, the vertical rod 5 is inserted into the main rod 1. Then, the vertical rod 5 is rotated to tightly sleeve the screw cap 10 with the upper end of the main rod 1, thereby achieving a firm fixation.

[0027] A horizontal bar 7 is installed on one side of the vertical bar 5. An adjusting sleeve 6 is provided between the vertical bar 5 and the horizontal bar 7. The adjusting sleeve 6 includes two sleeves 61 that are fixedly connected to each other perpendicularly. The vertical bar 5 passes through the vertically set sleeve 61, and the horizontal bar 7 passes through the horizontally set sleeve 61.

[0028] Both sleeves 61 have adjusting screws 62 fitted to their outer ends. By tightening the adjusting screws 62, the ends of the screws can be pressed against the vertical rod 5 or the horizontal rod 7 to achieve a firm fixation. By loosening the adjusting screws 62, the height of the vertical rod 5 or the extension length of the horizontal rod 7 can be smoothly adjusted to meet the needs of different shooting distances.

[0029] An angle adjustment mechanism 8 is provided at the end of the crossbar 7 for adjusting and controlling the projection angle of the XRF analyzer. The angle adjustment mechanism 8 includes a sealed housing 81, a worm gear 82, and a worm 83. The worm gear 82 and the worm 83 are rotatably connected inside the housing 81. One end of the worm 83 extends out of the housing 81 and is fixedly connected to a knob 84. A rotating shaft is coaxially fixed at the center of the worm gear 82. The rotating shaft extends out of the housing 81 and is fixedly connected to a fixed gripper 91.

[0030] Rotating knob 84 drives worm gear 83 to rotate, which in turn drives worm wheel 82 to rotate, thus enabling fine-tuning of the angle of clamp 9. Worm gear transmission features a large transmission ratio and good self-locking properties, ensuring that the X-ray equipment remains stable after angle adjustment and preventing the image quality from being affected by angle deviation.

[0031] An angle adjustment mechanism 8 has a clamp 9 installed at its outer end. The clamp 9 is used to hold and fix the portable X-ray equipment. The clamp 9 includes a fixed jaw 91 and a movable jaw 92. The fixed jaw 91 is fixedly connected to the shaft end of the worm gear 82. The movable jaw 92 is rotatably connected to the fixed jaw 91 through a stainless steel hinge shaft. A stud 93 is installed on the inner side of the fixed jaw 91. The stud 93 passes through the movable jaw 92, and a spring is sleeved in the middle of the stud 93. An adjustment head 94 is threaded to the outer end.

[0032] The rotating adjustment head 94 allows for adjustment of the opening size of the two grippers to accommodate different models of X-ray equipment. Springs provide cushioning. The outer ends of both grippers are covered with anti-slip silicone pads (not shown in the diagram), which protect the equipment surface and enhance clamping stability.

[0033] The working principle of this utility model is as follows: When in use, first unfold the three sleeve rods 2 to form a stable support. Choose to use the support foot 3 or the moving mechanism 4 according to the usage requirements: when it is necessary to move the equipment, put down the clamp rod 41 and use the pulley 42 to move the equipment. After it is in place, step on the brake device to fix it; when it is necessary to shoot for a long time, retract the clamp rod 41 and use the support foot 3.

[0034] The height of the vertical rod 5 can be adjusted by adjusting the screw cap 10, the extension length and height of the horizontal rod 7 can be adjusted by adjusting the sleeve 6, and the projection angle of the XRF analyzer can be adjusted by adjusting the angle adjustment mechanism 8.

[0035] Clamp 9 securely and gently holds the XRF analyzer, ensuring stability during imaging. After use, the components can be folded up for easy storage and future use.

[0036] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
