[0002] Medical X-ray machines play an irreplaceable role in modern medical diagnosis and are widely used in the examination and diagnosis of various diseases. Through X-ray imaging technology, doctors can clearly observe the structures inside the patient's body, providing an important basis for the accurate diagnosis and treatment of diseases.

[0003] The main structure of an X-ray machine includes a transverse support, which is used to adjust the position. After the position is adjusted, the transverse support needs to be braked. The existing transverse support braking mechanism mainly uses friction to brake the movement of the transverse support, but it does not completely lock it. When subjected to a large external force, the transverse support can still move, resulting in inaccurate positioning during use. Utility Model Content

[0004] The purpose of this utility model is to provide a locking mechanism for a transverse support, which solves the problem that the existing transverse support uses friction for braking, which may slip under external force and affect the positioning accuracy.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] See Figures 1-9As shown, this embodiment of the present invention proposes a locking mechanism for a transverse support 1, including a transverse support 1 integrated on an X-ray machine, wherein the transverse support 1 is provided with a plurality of first locking teeth 2 evenly distributed along its length; a support base 3 mounted on the X-ray machine and a locking block 4 slidably mounted on the support base 3, wherein the locking block 4 is provided with a plurality of second locking teeth 5 evenly distributed along its length. Specifically, the transverse support 1 and the support base 3 are both integrated inside the X-ray machine. After the transverse support 1 has been adjusted in position, it needs to be locked to prevent movement and ensure stability during the imaging process. This embodiment mainly improves the relevant structure for reliable locking of the transverse support 1, while other parts constituting the X-ray machine are existing technologies and are not discussed in this embodiment. Therefore, when the second locking teeth 5 provided on the locking block 4 engage with the first locking teeth 2 on the transverse support 1, braking is achieved, while when disengaged, the transverse support 1 can move.

[0030] To facilitate the movement of the locking block 4 and the locking of its position, an adjustment mechanism 6 is provided on the support base 3. The adjustment mechanism 6 adjusts the sliding of the locking block 4 relative to the support base 3 to achieve engagement or disengagement of the second locking tooth 5 with the first locking tooth 2. That is, the sliding action of the locking block 4 relative to the support base 3 needs to be driven by the adjustment mechanism 6, and the adjustment mechanism 6 also locks the movement state of the locking block 4. After the locking block 4 abuts against the transverse support 1, it ensures that the first locking tooth 2 and the second locking tooth 5 are engaged to achieve braking of the transverse support 1. Under the action of external force, the transverse support 1 will not cause relative positional movement.

[0031] Specifically, the adjustment mechanism 6 includes a threaded rod 61 rotatably mounted on the support base 3. The threaded rod 61 is threadedly engaged with the locking block 4. An adjustment handle 62 is connected to the part of the threaded rod 61 that extends out of the support base 3. The threaded rod 61 is driven to rotate by the adjustment handle 62, which in turn drives the locking block 4 to slide relative to the support base 3. Self-locking can be achieved at any position, ensuring that the position of the locking block 4 will not change after adjustment.

[0032] Meanwhile, in order to further improve the speed during the adjustment process and complete a large stroke adjustment in a shorter distance, a first threaded part 611 and a second threaded part 612 are provided on the threaded rod 61. The second threaded part 612 is threadedly connected to the locking block 4, and the first threaded part 611 is threadedly connected to the support base 3. The first threaded part 611 and the second threaded part 612 are opposite threads; that is, when the threaded rod 61 rotates relative to the support base 3, it also moves, and at the same time drives the locking block 4 to slide relative to the support base 3, thereby increasing the moving speed of the locking block 4. This makes it convenient to quickly adjust the locking block 4 when the transverse support 1 is adjusted to the correct position or when the position of the transverse support 1 needs to be adjusted.

[0033] Meanwhile, to prevent slippage when the adjusting handle 62 rotates the threaded rod 61, a hexagonal connecting part 613 is provided at the end of the threaded rod 61. The adjusting handle 62 is provided with a mounting hole 620 for inserting the connecting part 613, and a fastening screw for locking the connecting part 613. The hexagonal cross-section is used to prevent the connecting part 613 from rotating, ensuring that the threaded rod 61 and the adjusting handle 62 rotate synchronously. The fastening screw locks the connecting part 613, thereby achieving a reliable connection.

[0034] Specifically, a first sliding groove for slidingly mounting the locking block 4 is provided on the support base 3, and two second sliding grooves are provided on both sides of the first sliding groove. A guide rod 7 is slidably mounted in the second sliding groove, and the guide rod 7 is connected to the locking block 4. A spring 8 is provided in the second sliding groove and sleeved on the guide rod 7. The part of the guide rod 7 that extends out of the support base 3 is provided with a limiting end. This allows the locking block 4 to have a certain floating effect relative to the support base 3. During the process of the second locking tooth 5 on the locking block 4 contacting the first locking tooth 2 on the transverse support 1 and engaging, adaptive floating can be achieved to ensure that the first locking tooth 2 and the second locking tooth 5 can engage quickly and smoothly.

[0035] The locking block 4 slides relative to the support base 3 and floats relative to it via the guide rod 7 and the spring 8. The locking block 4 itself also needs to have a structure that can meet the floating adjustment. Specifically, the locking block 4 includes a stop block 41 and a connecting block 42. The stop block 41 is provided with a mounting groove 45 and sliding arms 46 located on both sides of the mounting groove 45. Two strip holes 43 are opened at intervals on the sliding arms 46. A sliding pin 44 is provided in the strip hole 43. The sliding pin 44 extends into the mounting groove 45 and locks on the connecting block 42. The connecting block 42 is connected to the threaded rod 61. By passing the sliding pin 44 through the strip hole 43 and fixing it to the connecting block 42, the stop block 41 has a floating range in the lateral direction relative to the connecting block 42. When the first locking tooth 2 and the second locking tooth 5 are engaged, it can move adaptively to ensure that the engagement is in place. The connecting block 42 slides relative to the support base 3 and is driven by the threaded rod 61 to slide up and down, thereby pulling the stop block 41 to move up and down synchronously. It also forms a sliding fit with the support base 3 through the sliding arm 46, further ensuring the stable state of the stop block 41 during floating adjustment. Specifically, the guide rod 7 is connected to the stop block 41, and the first locking tooth 2 is provided on the stop block 41.

[0036] Specifically, a first step 33 is provided on the support base 3, and the sliding arm 46 slides in cooperation with the first step 33. The first step 33 positions and guides the sliding arm 46 to ensure that the relative floating movement of the stop block 41 is smooth, and the support base 3 serves as the sliding reference.

[0037] To facilitate the stable installation of the support base 3 on the X-ray machine and thus ensure reliable installation of the entire locking mechanism, first fastening holes 34 are provided at intervals on the support base 3. At the same time, outwardly extending mounting blocks 35 are provided at both ends of the support base 3, and second fastening holes 36 are provided on the mounting blocks 35. This achieves fastening installation on both sides and the main load-bearing side, ensuring stability.
