Description

Technical Field

[0001] The utility model relates to medical equipment, in particular to a steel ball locking device. Background Art

[0002] As a fundamental medical device, the operating table holds a crucial position in orthopedics, surgery, and other medical device categories. They are not only essential tools for doctors during surgery but also crucial tools frequently used by patients during their postoperative recovery. With the continuous advancement of medical technology, the variety and functionality of operating tables are becoming increasingly diverse. From the most basic lifting function, these have expanded to include partial lifting, rotation, suspension, and tilting, and even more combinations, such as the ability to slide when needed and secure when not; to elevate the legs when needed and lay them flat when not needed; and so on, allowing for diverse functions tailored to specific situations.

[0003] In order to achieve the above-mentioned multiple combination functions, the bed body is usually composed of a headboard, an upper backboard, a lower backboard, a seat board and a leg board connected in sequence, and the two are connected by a number of hinged devices. During assembly or subsequent maintenance, the disassembly of the hinged devices is cumbersome and inefficient. Therefore, the development of a locking device that can achieve quick assembly at one end is a technical problem that needs to be urgently solved in this case. Utility Model Content

[0004] In view of the above problems, the utility model provides a steel ball locking device with a sophisticated structure and efficient assembly connection at one end.

[0005] The technical solution of the utility model is:

[0006] Ball locking device, including:

[0007] A locking seat, one end of which is provided with a locking hole and the other end of which is provided with a connecting end; a side portion of the locking seat is provided with a pressing hole connected to the locking hole;

[0008] A pressing rod can be pressed into the pressing hole and reset by a first spring at the tail; the pressing rod is provided with a V-shaped notch;

[0009] An actuator rod is slidably disposed in the locking hole, and a rotatable roller is provided at the tail end. The roller is positioned in the notch by being squeezed by a second spring at the front end. The actuator rod is provided with a locking area, a slope area, and a sedimentation groove connected in sequence.

[0010] The locking seat is provided with a limiting hole adapted to the steel ball. The top of the steel ball is extended from the limiting hole through the support of the locking area. After the pressing rod is pressed, it overcomes the elastic force of the first spring and slides in the pressing hole. Through the action of the inclined surface of the notch, the executive rod overcomes the elastic force of the second spring and rolls the steel ball into the sedimentation tank to achieve unlocking.

[0011] Specifically, a spring hole is provided at the tail of the pressing rod;

[0012] The first spring end extends into the spring hole.

[0013] Specifically, the second spring is limited in the locking hole by a clip at the opening of the locking hole.

[0015] Specifically, the seat body is provided with a positioning rod fixedly arranged parallel to the extension tube.

[0016] Specifically, the cross section of the connecting end is a C-shaped structure, with a connecting port provided in the middle.

[0017] Specifically, a leg support seat that can be rotatably fixed is provided in the connecting port.

[0018] Specifically, the connecting end is a connecting ear;

[0019] The connecting ear is provided with a connecting hole.

[0020] This utility model includes a locking seat, a pressing rod, an actuator rod, and a steel ball. When the pressing rod is released, a first spring resets, pushing the pressing rod back to its original position, causing the roller to enter the bottom of the notch. At this point, a second spring resets, pushing the actuator rod toward the pressing rod. The top surface of the locking area on the actuator rod connects to the steel ball, and the top of the steel ball extends from the limit hole to achieve locking. This utility model has the advantages of a compact structure and efficient one-end assembly connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] An upper gear ring is provided in the connection port and is sleeved on the connection shaft. The upper gear ring is meshed with the lower gear ring.

[0059] The top of the connecting shaft is connected to the locking seat 100 through a thread, and the upper gear ring and the lower gear ring are locked by rotating the connecting shaft (a step is provided between the connecting shaft and the bottom surface of the upper gear ring, and the upper gear ring is driven to move upward by the upward rotation of the connecting shaft), thereby fixing the leg board support seat 700 and thus fixing the leg board.

[0060] Example 2:

[0061] like Figure 6 As shown; the connecting end 120 is a connecting ear 800;

[0062] The connecting ear 800 is provided with a connecting hole, and the end of the head plate is detachably fixedly connected to the connecting ear 800.
