[0002] Mobile X-ray stands are often used in medical settings to facilitate flexible X-ray examinations of patients. However, traditional stands are often large in size and inconvenient to move and store. To address these issues, a stand design with a folding device has emerged. This device allows the stand to be easily folded when not in use, reducing the space occupied and improving the convenience of transportation. It is suitable for a variety of occasions such as hospitals or temporary treatment sites.
[0003] However, in actual use, traditional folding devices usually use a limiting structure to prevent them from shaking while moving.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present invention, by providing a folding limit mechanism, when the user needs to fold the folding bracket body, the user can rotate the folding bracket body and place it on the top of the mobile base frame, and then the user releases the lifting handle. At this time, the reset spring pushes the limit plate to insert the locking plate into the stabilizing groove on the inner side of the mounting sleeve. During the transportation of the folding X-ray imaging device body, when the mobile base frame shakes due to uneven road surface, the mobile base frame transmits the vibration to the shock-absorbing spring. The shock-absorbing spring can effectively absorb and buffer the vibration caused by uneven road surface or other external forces, reduce the vibration of the folding bracket body and the X-ray imaging device body, and extend the service life of the X-ray imaging device body. On the one hand, the locking plate provides a stable limit for the folding bracket body.

[0017] 2. In the present invention, by providing a stabilizing mechanism, when the user needs to place the folding bracket body, the user can observe the leveling ball in the leveling groove in advance. When the mobile chassis is placed on a relatively flat ground, the leveling ball stays on the top of the lifting plate. As the leveling ball stays for too long, the weight of the leveling ball causes the lifting plate to slowly descend. The slowly descending lifting plate squeezes the two spring rods. At this time, it can be determined that the current area is relatively flat, thereby avoiding mechanical wear caused by the tilt of the folding bracket body and reducing the tilt or distortion of the image caused by the uneven ground when the X-ray imaging device body is photographed, which affects the doctor's diagnosis. Accuracy, when the leveling ball is placed in the storage slot, the user can pull out the two locking pins, and the two stabilizing legs will slide down from the bottom ends of the two fixed supports, and the two stabilizing legs will fit the ground. Then the user will pass the two locking pins through the two through slots to fix the stabilizing legs and the fixed supports. At this time, the mobile base frame cannot move, and then the user can press the connecting plate to insert the two locking rods at the bottom of the connecting plate into the two locking holes respectively. At this time, the stabilizing plate and the fixed plate are limited, and the stabilizing plate can prevent the folding bracket body from excessive rotation, and can enhance the stability of the folding bracket body, thereby ensuring the stable placement of the folding bracket body.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Specifically, Figure 1-2As shown, a support arm 2 is installed at the top of the folding bracket body 4, an X-ray device body 3 is installed at the bottom of the support arm 2, a top plate 8 is fixedly connected to one side of the top of the movable base frame 1, and a placement groove 7 is opened on the back of the folding bracket body 4.
[0023] Among the above components, the combination of the arm 2 and the X-ray device body 3 provides a stable support. At the same time, the design of the arm 2 allows angle adjustment to adapt to different shooting requirements. In addition, the placement slot 7 provides additional storage space for the arm 2, which is convenient for storing accessories and tools, thereby improving the convenience of use.
[0024] Specifically, Figure 3-4 As shown, two locking boxes 501 are fixedly connected to the top of the mobile base frame 1, and the interiors of the two locking boxes 501 are slidably connected to the limiting plates 511, and the back of the limiting plates 511 is fixedly connected to a return spring 509, one end of the return spring 509 is fixedly connected to one side of the inner wall of the locking box 501, and the front of the limiting plate 511 is fixedly connected to a locking plate 505, one end of the locking plate 505 passes through the locking box 501, and the inner walls of the two locking boxes 501 are slidably connected to unlocking plates 510.
[0025] Among the above-mentioned components, the limit plate 511 slidingly connected in the locking box 501 can automatically return to its original position through the action of the reset spring 509. When unlocking, the user can operate the unlocking plate 510 to move the limit plate 511, thereby releasing the connection between the locking plate 505 and the limit plate 511. At this time, the reset spring 509 will push the limit plate 511 to return to the preset position.
[0026] Specifically, Figure 1-6 As shown, the inner side of the unlocking plate 510 is attached to the outer side of the limiting plate 511, the bottom end of the gear ring 508 is rotatably connected to the top of the movable base frame 1, the inner wall of the gear ring 508 is fixedly connected with the mounting tube 507, the inner wall of the mounting tube 507 is vertically slidably connected with the lifting handle 506, the top of the top plate 8 is provided with a limiting groove 512, one end of the lifting plate 613 is inserted into the inner wall of the limiting groove 512, two racks 504 are meshed on both sides of the gear ring 508, the bottom ends of the two racks 504 are slidably connected to the top of the movable base frame 1, one end of the two racks 504 respectively penetrates the two locking boxes 501, and is fixedly connected to the two unlocking plates 510 respectively.
[0027] In the above-mentioned components, the mounting tube 507 is vertically slidably connected to the lifting handle 506, but when the lifting handle 506 rotates, the mounting tube 507 can be driven to rotate, and the mounting tube 507 thereby drives the gear ring 508 to rotate, and the gear ring 508 can engage with the two racks 504. When the gear ring 508 rotates, the two racks 504 can be moved closer to or away from each other, thereby controlling the movement of the two unlocking plates 510. After the movement, the user can insert one end of the lifting handle 506 into the limiting groove 512 to prevent the gear ring 508 from rotating, thereby improving its stability.
[0028] Specifically, Fig. 9 As shown, both side walls of the folding bracket body 4 are provided with mounting grooves 502, the inner wall of the mounting groove 502 is slidably connected with a mounting sleeve 503, both side walls of the mounting sleeve 503 are fixedly connected with shock-absorbing springs 513, one end of the two shock-absorbing springs 513 are respectively fixedly connected to the two sides of the inner wall of the mounting groove 502, a stabilizing groove 514 is provided on the front side of the mounting sleeve 503, and the size of the locking plate 505 matches the size of the stabilizing groove 514.
[0029] In the above components, when the mobile chassis 1 shakes, the shaking will be transmitted to the locking plate 505, and the locking plate 505 further transmits the shaking to the mounting sleeve 503. The shock absorbing springs 513 installed on both sides of the mounting sleeve 503 can effectively reduce the vibration, on the one hand, maintaining the limiting function of the locking plate 505, and on the other hand, providing a certain activity space for it, thereby achieving a better shock absorbing effect.
[0030] Specifically, Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 8 As shown, the bottom ends of the two fixed supports 602 are fixedly connected to the top of the movable base frame 1, and the two sides of the folding bracket body 4 are respectively hinged to the inner sides of the two fixed supports 602, and the bottom ends of the inner walls of the two fixed supports 602 are vertically slidably connected to two stable legs 601, and the outer sides of the two fixed supports 602 and the two stable legs 601 are provided with through grooves 610, and one end of the locking pin 603 passes through the two through grooves 610.
[0031] In the above-mentioned components, the bottom ends of the two fixed supports 602 are fixedly connected to the top of the mobile base frame 1, providing a stable supporting foundation, and the two sides of the folding bracket body 4 are respectively connected to the inner sides of the two fixed supports 602 through hinge structures, allowing it to be flexibly folded and unfolded. The bottom end of the inner wall of the fixed support 602 is vertically slidably connected to two stabilizing legs 601, further enhancing the overall stability. In order to facilitate locking and fixing, the outer sides of the fixed support 602 and the stabilizing legs 601 are provided with through grooves 610, and one end of the locking pin 603 passes through the two through grooves 610, ensuring that locking and unlocking operations can be performed quickly and safely during use.
[0032] Specifically, Figure 7 As shown, the inner side of the fixing plate 609 is fixedly connected to the back side of the folding bracket body 4, a locking hole 608 is opened at the top of the fixing plate 609, and two locking rods 606 are fixedly connected to the bottom end of the connecting plate 605. The bottom ends of the two locking rods 606 pass through the stabilizing plate 604 and are respectively inserted into the inside of the two locking holes 608.
[0033] In the above components, the bottom end of the connecting plate 605 is fixedly connected to two locking rods 606, the bottom ends of these locking rods 606 penetrate the stabilizing plate 604, and are respectively inserted into the two locking holes 608. This design ensures that the locking rods 606 can firmly fix the folding bracket body 4 during operation to prevent its accidental displacement, thereby improving the overall stability and safety. Specifically, Figure 7-8 As shown, the bottom end of the stabilizing plate 604 is fixedly connected to the top of the movable base frame 1, the inner side of the stabilizing plate 604 is attached to the back side of the folding bracket body 4, a leveling groove 607 is provided at the top of the stabilizing plate 604, a leveling ball 614 is placed on the inner wall of the leveling groove 607, a storage groove 611 is provided at the bottom end of the leveling groove 607, two spring rods 612 are fixedly connected to the inner wall of the storage groove 611, a lifting plate 613 is fixedly connected to the top of the two spring rods 612, and the lifting plate 613 is slidably connected to the inner wall of the storage groove 611.
[0034] Among the above-mentioned components, the inner side of the stabilizing plate 604 is attached to the back side of the folding bracket body 4, which effectively prevents the device from shaking during use. The leveling ball 614 can provide precise horizontal adjustment during use. The elastic force of the spring rod 612 is relatively weak. When the leveling ball 614 stays on the lifting plate 613 for too long, the lifting plate 613 will slowly descend due to the gravity of the leveling ball 614.
[0035] Working principle, when in use: when the user needs to fold the folding bracket body 4, the user can fold the support arm 2, and the support arm 2 is placed in the placement groove 7. The user can pull the lifting handle 506 upward in advance to release the lifting handle 506 from the limiting groove 512, and then the user can rotate the lifting handle 506, and the lifting handle 506 drives the installation cylinder 507 to rotate, and the installation cylinder 507 drives the gear ring 508 to rotate, and the gear ring 508 drives the two racks 504 to squeeze the two unlocking plates 510 inside the two locking boxes 501 respectively, and the two unlocking plates 510 drive the limiting plate 511 to move, and the limiting plate 511 pulls the locking plate 505 into the interior of the locking box 501, and then the user can rotate the folding bracket body 4. The movable base frame 1 is moved and placed on the top of the movable base frame 1, and then the user releases the lifting handle 506. At this time, the return spring 509 pushes the limit plate 511 to insert the locking plate 505 into the stabilizing groove 514 on the inner side of the mounting sleeve 503. During the transportation of the foldable X-ray imaging device body 3, when the movable base frame 1 shakes due to the uneven road surface, the movable base frame 1 transmits the vibration to the shock-absorbing spring 513. The shock-absorbing spring 513 can effectively absorb and buffer the vibration caused by the uneven road surface or other external forces, reduce the vibration of the folding bracket body 4 and the X-ray imaging device body 3, and extend the service life of the X-ray imaging device body 3. On the one hand, the locking plate 505 provides a stable limit for the folding bracket body 4, and on the other hand, the mounting sleeve 503 and the shock-absorbing spring The synergistic effect of the spring 513 significantly reduces the damage caused by vibration, further protecting the safety and stability of the X-ray imaging device body 3. When the user needs to place the folding bracket body 4, the user can observe the leveling ball 614 in the leveling groove 607 in advance. When the mobile base frame 1 is placed on a relatively flat ground, the leveling ball 614 stays on the top of the lifting plate 613. As the leveling ball 614 stays for too long, the weight of the leveling ball 614 causes the lifting plate 613 to slowly descend. The slowly descending lifting plate 613 squeezes the two spring rods 612. At this time, it can be determined that the current area is relatively flat, avoiding mechanical wear caused by the tilt of the folding bracket body 4, and reducing the uneven bottom platform when the X-ray imaging device body 3 is taken. This causes the image to be tilted or distorted, affecting the accuracy of the doctor's diagnosis. When the leveling ball 614 is placed in the storage slot 611, the user can pull out the two locking pins 603, and the two stabilizing legs 601 slide down from the bottom ends of the two fixed supports 602. The two stabilizing legs 601 are in contact with the ground. Then the user passes the two locking pins 603 through the two through slots 610, thereby fixing the stabilizing legs 601 and the fixed supports 602. At this time, the mobile base frame 1 cannot move. Then the user can press the connecting plate 605 to insert the two locking rods 606 at the bottom of the connecting plate 605 into the two locking holes 608 respectively. At this time, the stabilizing plate 604 and the fixed plate 609 are limited, and the stabilizing plate 604 can prevent the folding bracket body 4 from rotating excessively.And it can enhance the stability of the folding bracket body 4, ensuring the stable placement of the folding bracket body 4.
[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
