[0003] Traditional medical pendant arm mechanisms often require tools and a considerable amount of time to disassemble when replacing the arm body. This cumbersome operation is extremely inconvenient in confined medical spaces, making it difficult to replace the arm body. Utility Model Content

[0004] The purpose of this utility model is to provide a medical pendant arm mechanism that solves the problem that traditional medical pendant arm mechanisms often require tools and a long time to disassemble when replacing the arm body, making the operation cumbersome and extremely inconvenient in confined medical spaces, thus making it difficult to replace the arm body.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a medical pendant arm mechanism, comprising a base, a connecting rod fixedly mounted on the upper surface of the base, a fixing block fixedly mounted on the upper surface of the connecting rod, a cylinder fixedly mounted on the upper surface of the base, an installation plate fixedly mounted on the output end of the cylinder, a rotation adjustment mechanism provided on the lower surface of the base, a quick-release mechanism provided on the lower surface of the rotation adjustment mechanism, and a fixed end of the quick-release mechanism provided on the lower surface of the rotation adjustment mechanism.

[0006] The rotation adjustment mechanism includes a motor. The motor is fixedly installed on the upper surface of the base. A rotating shaft is fixedly installed at the output end of the motor. The rotating shaft extends to the lower surface of the base. A fixing plate is sleeved on the outer surface of the rotating shaft. One end of the fixing plate is connected to the lower surface of the base.

[0007] A drive wheel is fitted onto the outer surface of the rotating shaft. One end of the drive wheel is connected to the upper surface of the fixed disk. A belt is fitted onto the outer surface of the drive wheel. A driven wheel is rotatably connected to the lower surface of the mounting disk. The drive wheel is connected to the driven wheel via the belt. A fixed rod is fixedly installed inside the driven wheel.

[0008] The quick-release mechanism includes a mounting plate, on the lower surface of the fixing rod, a connecting block is fixedly mounted on the lower surface of the mounting plate, and a snap-fit ​​groove is formed on the outer surface of the connecting block.

[0009] The lower surface of the mounting plate is into which the boom body is inserted. The upper surface of the boom body is provided with a rectangular groove. The bottom end of the connecting block is inserted into the inner bottom of the rectangular groove. The interior of the rectangular groove is provided with an installation groove.

[0010] A fixing plate is fixedly installed on the inner wall of the mounting groove, and a spring is fixedly installed on the outer surface of the fixing plate. A snap-fit ​​block is fixedly installed on one end of the spring, and one end of the snap-fit ​​block is snapped into the inside of the snap-fit ​​groove.

[0011] This utility model has the following beneficial effects: (1) When the boom body needs to be replaced, the present invention can be used by manually pulling the locking block outward to disengage it from the locking slot, and the boom body can be taken out downward to achieve quick separation. Then, the rectangular groove at the upper end of the new boom body is aligned and put on the connecting block. During the insertion process, the connecting block will squeeze the locking block, causing it to compress the spring and retract. When the locking slot on the connecting block moves to align with the locking block, the restoring force of the spring will push the locking block to pop out and lock into the locking slot, thus firmly locking the boom body to the upper mechanism, thereby achieving the effect of quick disassembly and installation. This avoids the situation in the prior art where disassembling the boom body often requires tools and a long time, is cumbersome to operate, and is extremely inconvenient in a small medical space, which leads to the difficulty of replacing the boom body.

[0012] (2) When the angle of the boom body needs to be adjusted, the present invention starts the motor, and its output end drives the rotating shaft to rotate. The rotating shaft drives the drive wheel on it to rotate. The drive wheel transmits power to the driven wheel through the belt, thereby achieving the effect of rotating the fixed rod and the boom body below it around the axis, realizing the horizontal orientation adjustment effect of the tower arm.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Its design also takes into account the need for a firm connection with the ceiling structure and internal wiring. Connecting rod 2: Connecting rod 2 is a rigid support connecting the base and the ceiling. It can be adjusted according to the actual height of the installation site. Its surface is often treated with anti-corrosion to adapt to long-term use in the hospital environment. Fixing block 3: Fixing block 3 is used to lock the connecting rod 2 to the ceiling. It is usually rigidly connected by high-strength bolts. Its structural design fully considers the load-bearing capacity and vibration resistance to ensure the stability of the overall mechanism. Cylinder 4: Cylinder 4 is the core of the lifting function. It achieves smooth linear motion through air pressure control. Its selection focuses on load capacity and operating noise to meet the requirements of the medical environment for quiet operation and precise adjustment. Mounting plate 5: Mounting plate 5 is directly connected to the cylinder output end and serves as a mounting platform for transmission components. Its plate surface has a high degree of flatness and is designed with multiple mounting holes to ensure transmission alignment and adapt to different accessories. Rotation adjustment mechanism 6: This mechanism is the key to achieving horizontal rotation. It is driven by motor 601 and transmits power through belt 605, thereby driving the boom to rotate horizontally and realizing a wide range of orientation adjustment of the tower boom in the horizontal plane. Quick-release mechanism 7: This mechanism enables the rapid connection and separation of the boom body and the upper drive structure without the need for any tools, greatly simplifying the boom replacement process and improving the efficiency of equipment maintenance.

[0018] The rotary adjustment mechanism 6 includes a motor 601. The motor 601 is fixedly installed on the upper surface of the base 1. A rotating shaft 602 is fixedly installed at the output end of the motor 601. The rotating shaft 602 extends to the lower surface of the base 1. A fixed plate 603 is sleeved on the outer surface of the rotating shaft 602. One end of the fixed plate 603 is connected to the lower surface of the base 1. Motor 601: As the power source of the rotating mechanism, motor 601 is usually selected as a low-noise, high-precision servo or stepper motor to ensure that the rotation process is smooth and controllable and to avoid impact on the suspended medical equipment. Shaft 602: Shaft 602 is the core power transmission component. It transmits the rotational torque of the motor downwards. Its manufacturing precision and material strength are crucial and directly affect the stability and lifespan of the entire rotation system. Fixed disk 603: Fixed disk 603 provides stable support and positioning for rotating parts. It ensures that components such as shaft 602 and drive wheel 604 maintain the correct relative position during operation and prevents axial movement.

[0019] A drive wheel 604 is sleeved on the outer surface of the rotating shaft 602. One end of the drive wheel 604 is connected to the upper surface of the fixed disk 603. A belt 605 is sleeved on the outer surface of the drive wheel 604. A driven wheel 606 is rotatably connected to the lower surface of the mounting disk 5. The drive wheel 604 is connected to the driven wheel 606 through the belt 605. A fixing rod 607 is fixedly installed inside the driven wheel 606. Drive pulley 604: Drive pulley 604 is fixedly mounted on shaft 602 and serves as the drive end of the transmission system. Its tooth profile or groove is precisely matched with belt 605, which can efficiently transmit the power of the motor. Belt 605: Belt 605 connects the driving pulley and the driven pulley. As a flexible transmission element, it has the characteristics of buffering and shock absorption, smooth operation, and can adapt to certain center distance changes, which facilitates the layout of the mechanism. Driven wheel 606: Driven wheel 606 rotates under the drive of belt and transmits power to fixed rod 607. Its rotation speed is proportional to that of the driving wheel and together they determine the final rotation speed of the boom. Fixed rod 607: Fixed rod 607 is the connecting part between the driven wheel and the quick release mechanism below. It transmits the rotational motion to the boom and needs to have sufficient torsional strength to withstand the torque during operation.

[0020] The quick-release mechanism 7 includes a mounting plate 701, the mounting plate 701 is fixedly mounted on the lower surface of the fixing rod 607, the connecting block 702 is fixedly mounted on the lower surface of the mounting plate 701, and the outer surface of the connecting block 702 is provided with a snap-fit ​​groove 703. Mounting plate 701: Mounting plate 701 is the mounting base of the quick-release mechanism. It is fixed to the lower end of the fixing rod 607 and provides a solid mounting and docking foundation for the connecting block 702 and the boom body 704. Connecting block 702: The connecting block 702 is designed as a protruding structure that can be inserted into the rectangular slot 705 of the boom body. The snap-fit ​​slot 703 on it is used to cooperate with the snap-fit ​​block 709 and is one of the key components to achieve quick locking. Snap-in slot 703: This slot is precisely opened on the outer surface of the connecting block 702. Its shape matches the end of the snap-in block 709, forming a reliable mechanical interlock. When the snap-in block is inserted under the action of spring force, it can provide solid tensile and shear resistance for the entire connection.

[0021] The lower surface of the mounting plate 701 is inserted with the boom body 704, the upper surface of the boom body 704 is provided with a rectangular groove 705, the bottom end of the connecting block 702 is inserted with the inner bottom of the rectangular groove 705, and the interior of the rectangular groove 705 is provided with a mounting groove 706. 704 boom body: The boom body 704 is a functional component that directly suspends medical equipment. It typically integrates gas pipelines and electrical circuits. Its structure is lightweight and sturdy, and its smooth surface is easy to clean and disinfect. Rectangular groove 705: This groove runs through the upper end of the boom body 704. Its inner wall dimensions are precisely machined to ensure a tight sliding fit with the connecting block 702. It not only provides accurate insertion guidance for the connecting block, but is also the core load-bearing structure for the entire quick-release mechanism to achieve force flow transmission. Mounting slot 706: Located on the inner wall of rectangular slot 705, mounting slot 706 provides dedicated space for the locking assembly consisting of fixing plate 707, spring 708 and snap-fit ​​block 709. Its depth and width are carefully designed to ensure that the locking assembly can work stably and without jamming.

[0022] A fixing plate 707 is fixedly installed on the inner wall of the mounting groove 706. A spring 708 is fixedly installed on the outer surface of the fixing plate 707. A snap-fit ​​block 709 is fixedly installed on one end of the spring 708. One end of the snap-fit ​​block 709 is snapped into the inside of the snap-fit ​​groove 703. Fixing plate 707: Fixing plate 707 is fixed in mounting groove 706 and provides a support point for one end of spring 708. It is the fixing part in the snap-locking function, and its installation position directly affects the reliability of snap-locking. Spring 708: Spring 708 provides the elastic force that moves the locking block 709 toward the locking groove 703. It is the core component for achieving automatic locking and maintaining the locked state. Its elastic force needs to be precisely calculated to ensure that the locking force is appropriate. Snap-in block 709: Snap-in block 709 can be snapped into the snap-in groove of the connecting block under the action of spring force. It can be unlocked by pulling it manually. Its contact surface is often designed as a bevel or arc surface to facilitate automatic guidance and locking during insertion.

[0023] In use, the base 1 is first fixed to the ceiling by the connecting rod 2 and the fixing block 3. Then, the cylinder 4 is started, and its output end drives the mounting plate 5 to move up and down. The mounting plate is connected to the driven wheel 606 through the belt 605, which drives the fixed rod 607 fixed to the driven wheel, as well as the entire quick-release mechanism 7 and the boom body 704 at its lower end to move up and down synchronously, realizing the flexible adjustment of the boom height. When it is necessary to adjust the angle of the boom body 704, the motor 601 is started, and its output end drives the rotating shaft 602 to rotate. The rotating shaft drives the drive wheel 604 on it to rotate. The drive wheel transmits power to the driven wheel 606 through the belt 605, thereby making the fixed rod and the boom body below it rotate around the axis, realizing the horizontal orientation adjustment effect of the boom. When the boom body 704 needs to be replaced, simply pull the locking block 709 outward manually to disengage it from the locking slot 703, allowing the boom body to be removed downwards for quick separation. Then, align the rectangular slot 705 on the upper end of the new boom body 704 with the connecting block 702 and place it on the connecting block 702. During insertion, the connecting block will press against the locking block 709, causing the compression spring 708 to retract. When the locking slot 703 on the connecting block moves to align with the locking block, the spring's restoring force will push the locking block out and into the locking slot, thus firmly locking the boom body to the upper mechanism. This achieves the effect of quick disassembly and installation, avoiding the difficulties that occur in the existing technology when replacing the boom body 704, where disassembling the boom often requires tools and takes a long time, is cumbersome, and is extremely inconvenient in confined medical spaces, making the replacement of the boom body 704 difficult.
