In industrial settings, it is commonly used to detect internal defects in metal castings and welded parts; in the medical field, it is used for examining human bones, chest areas, and other parts; and in security inspection, it is used for security screening of luggage and cargo.

[0003] A search revealed a utility model patent with Chinese patent publication number CN220109749U, which discloses a DR testing device, including a vertical plate, a DR testing device body assembly, a lifting plate, a moving plate, a sliding plate, a first spring, a pull handle, two connecting rods, and a base. The vertical plate is slidably disposed on the side end face of the base, and the vertical plate has a groove and multiple limiting grooves. The lifting plate has a through groove and a through slot. The inner wall of the through groove has a sliding groove. The sliding plate is slidably connected to the inner wall of the sliding groove, the sliding plate is connected to the moving plate, and the sliding plate is connected to the two connecting rods.

[0004] The aforementioned device adjusts the position of the detection equipment by setting up a lifting plate. However, it can only be adjusted vertically, with a limited range of movement, and cannot adapt to the usage requirements of different environments, leaving room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a 3D adjustment device for DR detection equipment in narrow spaces, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a 3D adjustment device for DR detection equipment in narrow spaces, comprising a support frame and four connecting frames. All four connecting frames are located on top of the support frame and are hinged end-to-end. Near the hinge point of two adjacent connecting frames, the same adjustment component is installed. The adjustment component includes a support base fixedly connected to the top of the outer wall of one of the adjacent connecting frames. A horizontally arranged worm gear is rotatably connected inside the support base. A worm wheel meshing with the worm gear is coaxially fixed to the rotation shaft of the top connecting frame. A motor is fixedly installed on the outer wall of one end of the support base. The output end of the motor is coaxially fixed to one end of the worm gear. A rotating component is installed between the support frame and the bottom connecting frame.

[0007] As a further preferred embodiment of this technical solution, the rotating assembly includes a mounting plate rotatably connected inside the support frame, with the bottommost connecting frame coaxially fixed to the top outer wall of the mounting plate, and a toothed ring coaxially fixed to the top outer wall of the mounting plate.

[0008] As a further preferred embodiment of this technical solution, a second motor is fixedly installed on the inner wall of the top of the support frame, and a gear is coaxially fixed at the output end of the second motor, the gear meshing with a gear ring.

[0009] This allows the mounting base for installing testing equipment to be moved to any position in space, and the device can also be retracted as needed without occupying too much space, ensuring that the testing equipment can work in confined environments. Starting the first motor outside the support base drives the worm gear to rotate rapidly. The worm gear, through meshing, drives the worm wheel to rotate, and the worm wheel drives the connecting frame connected to it to swing around the horizontal axis. With the cooperation of multiple adjustment components, adjustment to any position in the planar direction can be achieved. If it is necessary to adjust the mounting base to another planar position, starting the second motor at the bottom of the support frame drives the gear to rotate. The gear, through meshing, drives the gear ring to rotate, and the gear ring drives the mounting plate to rotate synchronously. The mounting plate transmits the rotational motion to the mounting base through the connecting frame, causing the mounting base to move to another planar position. Through the combination of the above planar direction adjustment and planar switching adjustment, the position adjustment of the mounting base in three-dimensional space can be achieved.

[0010] As a further preferred embodiment of this technical solution, a lifting assembly is installed inside the topmost connecting frame. The lifting assembly includes two guide rails fixedly connected to the inner walls on both sides of the connecting frame, and the same mounting seat is slidably sleeved between the two guide rails.

[0011] As a further preferred embodiment of this technical solution, a vertically arranged lead screw is rotatably connected inside the topmost connecting frame, the mounting seat is threaded onto the outside of the lead screw, and a motor is fixedly installed on the top outer wall of the connecting frame, with the output end of the motor being coaxially fixed with one end of the top of the lead screw.

[0012] Start the third motor at the top of the uppermost connecting frame. The third motor drives the lead screw to rotate, which in turn drives the mounting base to move along the guide rail, further increasing the range of motion of the mounting base.

[0013] As a further preferred embodiment of this technical solution, a through hole is provided at each of the four corner positions of the mounting base.

[0014] As a further preferred embodiment of this technical solution, the worm is a toroidal worm, and both the worm and the worm wheel are made of alloy steel.

[0015] This invention provides a 3D adjustment device for DR detection equipment in confined spaces, which has the following advantages:

[0016] (1) By setting adjustment components and rotation components, this utility model enables the mounting base for installing the testing equipment to be moved to any position in the space, and the device can also be retracted as needed without occupying too much space, ensuring that the testing equipment can work in a narrow environment. Start the motor one outside the support base. The motor one drives the worm gear to rotate rapidly. The worm gear drives the worm wheel to rotate through meshing. The worm wheel drives the connecting frame connected to it to swing around the horizontal axis. With the cooperation of multiple adjustment components, the adjustment of any position in the plane direction can be realized. If it is necessary to adjust the mounting base to the position of other planes, start the motor two at the bottom of the support frame. The output end of the motor two drives the gear to rotate. The gear drives the gear ring to rotate through meshing. The gear ring drives the mounting plate to rotate synchronously. The mounting plate transmits the rotational motion to the mounting base through the connecting frame, so that the mounting base moves to other plane positions. Through the combination of the above-mentioned plane direction adjustment and plane switching adjustment, the position adjustment of the mounting base in three-dimensional space can be realized.

[0017] (2) By setting up a lifting component, the third motor at the top of the uppermost connecting frame is started. The third motor drives the lead screw to rotate, and the lead screw can drive the mounting seat to move along the guide rail, which can further increase the range of movement of the mounting seat.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 2, Figure 3 As shown in Figure 4, in this embodiment, a 3D adjustment device for DR detection equipment in a narrow space includes a support frame 1 and four connecting frames 2. The four connecting frames 2 are all located on top of the support frame 1 and are hinged to each other end to end. Near the hinge of two adjacent connecting frames 2, the same adjustment component 3 is installed. The adjustment component 3 includes a support base 301 fixedly connected to the top of the outer wall of one of the two adjacent connecting frames 2. A horizontally arranged worm gear 302 is rotatably connected inside the support base 301. A worm wheel 303 that meshes with the worm gear 302 is coaxially fixed to the rotation shaft of the top connecting frame 2. A motor 304 is fixedly installed on the outer wall of one end of the support base 301. The output end of the motor 304 is coaxially fixed to one end of the worm gear 302. A rotating component 4 is installed between the support frame 1 and the bottom connecting frame 2.

[0025] To adjust the position of the mounting base 502, start the motor 304 outside the support base 301. The motor 304 drives the worm 302 to rotate rapidly. The worm 302 drives the worm wheel 303 to rotate through meshing. The worm wheel 303 drives the connecting frame 2 connected to it to swing around the horizontal axis. With the cooperation of multiple adjustment components 3, the adjustment can be achieved at any position in the planar direction.

[0026] The rotating assembly 4 includes a mounting plate 401 rotatably connected inside the support frame 1, a bottom connecting frame 2 coaxially fixed to the top outer wall of the mounting plate 401, and a toothed ring 402 coaxially fixed to the top outer wall of the mounting plate 401.

[0027] A second motor 404 is fixedly installed on the inner wall of the top of the support frame 1. A gear 403 is coaxially fixed at the output end of the second motor 404, and the gear 403 meshes with the gear ring 402.

[0028] To adjust the mounting base 502 to a different plane, start the second motor 404 at the bottom of the support frame 1. The output end of the second motor 404 drives the gear 403 to rotate. The gear 403 drives the gear ring 402 to rotate through meshing. The gear ring 402 drives the mounting plate 401 to rotate synchronously. The mounting plate 401 transmits the rotational motion to the mounting base 502 through the connecting frame 2, so that the mounting base 502 moves to a different plane. By combining the above-mentioned plane direction adjustment and plane switching adjustment, the position adjustment of the mounting base 502 in three-dimensional space can be realized.

[0029] like Figure 1 As shown in Figure 2, a lifting assembly 5 is installed inside the topmost connecting frame 2. The lifting assembly 5 includes two guide rails 501 fixedly connected to the inner walls on both sides of the connecting frame 2, and the same mounting seat 502 is slidably sleeved between the two guide rails 501.

[0030] The topmost connecting frame 2 is rotatably connected to a vertically arranged lead screw 503. The mounting base 502 is threaded onto the outside of the lead screw 503. A motor 3 504 is fixedly installed on the top outer wall of the connecting frame 2. The output end of the motor 3 504 is coaxially fixed with one end of the top of the lead screw 503.

[0031] If the position of the mounting base 502 needs to be lowered or raised again, the motor 3 504 at the top of the uppermost connecting bracket 2 is activated. The motor 3 504 drives the lead screw 503 to rotate, and the lead screw 503 can drive the mounting base 502 to move along the guide rail 501, which can further increase the range of movement of the mounting base 502.

[0032] like Figure 1 As shown in Figure 2, each of the four corners of the mounting base 502 has a through hole 505. The connector passes through the connecting foot of the testing equipment and the through hole, thus enabling the connection between the mounting base 502 and the testing equipment.

[0033] like Figure 3 As shown, the worm 302 adopts a toroidal worm. When the toroidal worm and the worm wheel mesh, multiple teeth usually participate in the meshing at the same time, which greatly improves the load-bearing capacity and reliability of the transmission and can stably support small DR testing equipment. In addition, both the worm 302 and the worm wheel 303 are made of alloy steel, which can obtain high surface hardness and core toughness, and can withstand large torque and friction.

[0034] This utility model provides a 3D adjustment device for DR detection equipment in confined spaces, and its specific working principle is as follows:

[0035] When the device is working, if it is necessary to adjust the position of the mounting base 502, start the motor 304 outside the support base 301. The motor 304 drives the worm gear 302 to rotate rapidly. The worm gear 302 drives the worm wheel 303 to rotate through meshing. The worm wheel 303 drives the connecting frame 2 connected to it to swing around the horizontal axis. With the cooperation of multiple adjustment components 3, the adjustment of any position in the planar direction can be achieved. If it is necessary to adjust the mounting base 502 to the position of other planes, start the motor 404 at the bottom of the support frame 1. The output end of the motor 404 drives the gear 403 to rotate. The gear 403 drives the gear ring 402 to rotate through meshing. The gear ring 402 drives the mounting plate 401 to rotate synchronously. The mounting plate 401 transmits the rotational motion to the mounting base 502 through the connecting frame 2, so that the mounting base 502 moves to other plane positions. Through the combination of the above-mentioned planar direction adjustment and planar switching adjustment, the position adjustment of the mounting base 502 in three-dimensional space can be achieved. If the position of the mounting base 502 needs to be lowered or raised again, the motor 3 504 at the top of the uppermost connecting bracket 2 is activated. The motor 3 504 drives the lead screw 503 to rotate, and the lead screw 503 can drive the mounting base 502 to move along the guide rail 501, which can further increase the range of movement of the mounting base 502.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
