Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and particularly relates to a locking mechanism for a support arm of a medical suspension tower. Background Technique

[0002] The suspension tower is an essential gas supply medical equipment in modern operating rooms of hospitals, mainly used for the terminal transfer of medical gases such as oxygen supply, suction, compressed air, and nitrogen in the operating room; it controls the lifting of the equipment platform by a motor, which is safe and reliable; the balanced design ensures the level of the equipment platform and the safety of the equipment; the drive of the motor ensures the rapid and effective operation of the equipment.

[0003] The search in the authorization announcement number: CN216962904U discloses a locking mechanism for a cantilever of a medical suspension tower, including a first cantilever, the right side of the bottom of the first cantilever is fixedly connected with a first rotating shaft, the bottom of the first rotating shaft is movably clamped with a second cantilever, the outer surface of the first rotating shaft is fixedly sleeved with a limiting gear, and the right side of the top of the second cantilever is movably installed with a positioning tooth pressing block located below the left side of the limiting gear. Through the positioning tooth pressing block, the threaded rod, the positioning rod, and the threaded sleeve, the utility model can rotate the threaded rod to drive the positioning tooth pressing block to move up and down under the limitation of the positioning rod and the second cantilever, so that the positioning tooth pressing block can be meshed with the limiting gear, and rotating the threaded sleeve can fixedly connect the threaded rod with the second cantilever, thereby ensuring that the positioning tooth pressing block and the limiting gear are always tightly meshed, so as to achieve a stable locking effect.

[0004] Although the above solution ensures that the positioning tooth pressing block and the limiting gear are always tightly meshed through the positioning tooth pressing block, the threaded rod, the positioning rod, and the threaded sleeve, so as to achieve a stable locking effect, when the second cantilever is adjusted for steering, the locking between the second cantilever and the medical equipment cannot be realized. Therefore, we propose a locking mechanism for a support arm of a medical suspension tower. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a locking mechanism for a support arm of a medical suspension tower, and by setting a rotation locking unit and a support unit, to solve the problem that when the second cantilever is adjusted for steering, the locking between the second cantilever and the medical equipment cannot be realized.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A locking mechanism for a support arm of a medical suspension tower includes a main body unit, and further includes a rotation locking unit and a support unit arranged above the main body unit, and a connection unit arranged above the support unit;

[0008] The rotation locking unit includes a fixed disk installed on the top of the main body unit, a rotating shaft movably arranged within the fixed disk, a gear disk installed on the side wall of the rotating shaft, and a locking member arranged within the fixed disk;

[0009] The support unit includes a second cantilever installed on the top of the rotating shaft, a connecting seat movably installed on the top of the second cantilever, a rotating seat installed on the top of the connecting seat, and an engaging member arranged below the rotating seat.

[0010] Preferably, the main body unit includes a medical device and a base installed at the bottom of the medical device.

[0011] Preferably, the main body unit further includes self-locking universal wheels installed at the bottom of the base.

[0013] Preferably, the rotation locking unit further includes a rotating handle installed on the side wall of the rotating shaft.

[0014] Preferably, the engaging member includes a T-shaped groove opened on the top of the second cantilever, a return spring installed on the bottom wall of the T-shaped groove, an engaging post installed on the top of the return spring, an annular engaging groove opened on the bottom of the rotating seat, and a pull rope installed at the bottom of the engaging post and passing through the T-shaped groove.

[0015] Preferably, the connecting unit includes a first cantilever installed on the top of the rotating seat and a connecting disk movably installed on the top of the first cantilever.

[0016] Compared with the prior art, the present utility model has the following beneficial effects:

[0017] In the present utility model, through the provided rotation locking unit and support unit, when the second cantilever needs to be adjusted in terms of its rotation direction, the rotating handle can be rotated, such that the rotating shaft drives the second cantilever at its top to rotate synchronously. When the second cantilever rotates to the corresponding position, under the elastic force of the connecting spring, the clamping plate will be clamped between adjacent teeth of the gear disk, thereby achieving the automatic locking between the second cantilever and the medical device after the rotation direction adjustment of the second cantilever; when the first cantilever needs to be adjusted in terms of its rotation direction, the pull rope can be pulled downward, such that the engaging post disengages from the annular engaging groove and compresses the return spring, thereby releasing the locking of the rotating seat. Subsequently, the first cantilever can be conveniently adjusted. After completing the rotation direction adjustment of the first cantilever, the force applied to the pull rope is removed, and under the elastic force of the return spring, the engaging post will automatically engage in the annular engaging groove, thereby achieving the automatic locking after the rotation direction adjustment of the first cantilever.
