Description

A connection device for weight reduction mechanism and suspension mechanism

technical field

The invention relates to a connection device between a weight reducing mechanism and a suspension mechanism.

Background technique

At this stage, most of the connections between the weight reduction mechanism and the suspension mechanism are connected by ropes and pulleys. The weight reduction mechanism pulls the rope and then changes the force direction through the pulley to drive the suspension mechanism to move to achieve the weight reduction effect. Design just needs to install coiling device and pulley installation device on the body, needs to take larger space. At the same time, when working, pulling the rope will bring a certain amount of noise, which is not good for the patient's experience; and the connection through the rope will also bring certain safety problems.

The slider a and the slider c are connected together through the connecting piece a; The connecting piece a is fixedly connected with the slider b, and the slider b is sleeved on the slide rail b, and can slide left and right along the slide rail b; the connecting piece a is fixedly connected with the connecting plate, and the two connecting plates connected together by connector b.

Preferably, the slide rail a is fixedly installed on the frame, specifically connected to the frame by screws; the slide rail b is fixedly mounted on the arm of the weight reducing mechanism, specifically connected to the arm of the weight reducing mechanism by screws; The connecting piece b is used to install the suspension mechanism, specifically, it is connected with the suspension mechanism by screws.

Preferably, the slider b is a rotatable slider.

Preferably, the connecting part a and the slider b are connected through bearings, specifically, the bearings are respectively screwed to the connecting part a and the slider b.

Preferably, the slider a and the slider c are connected through the connecting piece a, specifically, the slider a and the slider c are screwed to the connecting piece a respectively.

Preferably, the connecting piece a is screwed to the connecting plate, and the connecting plate is screwed to the connecting piece b.

Preferably, the slide rail a can be replaced with a screw rod, and electric equipment is mounted on the screw rod.

Preferably, the two symmetrical sliding rails a can be combined into one sliding rail.

Compared with the prior art, the present invention has the following beneficial effects:

1. The present invention adopts a modular design, which increases more adjustability than before, has strong flexibility, is convenient for disassembly and maintenance, and has a compact structure and is easy to install with the main body, effectively reducing the installation space. The parts are all simple parts, and the cost is low.

2. The present invention adopts detachable screw connection, which is convenient for installation and replacement of parts, which not only increases the service continuity of the overall structure, but also provides the possibility for users to modify the present invention according to their own needs.

3. The present invention does not use ropes and pulleys, but directly adopts modular design, which improves the safety and stability of the system and increases the comfort of patients.

4. The present invention mostly adopts the combination of slide rail and slide block, which effectively reduces the frictional force.
