Description

Supporting force angle self-adjusting structure of supporting frame

Technical Field

The utility model relates to a stay power angle self-interacting structure of support frame. Belongs to the technical field of support frames.

Background

The main effect of the lifting arm is that the height of the device can be freely adjusted and the device can hover at any position, and the lifting arms of the similar brackets in the current market are mainly divided into two categories: gas spring structures and mechanical spring structures.

At present, more than 95% of similar supports in the market are in gas spring structures, and the gas spring structures have the advantages of low development difficulty, low development cost, simple structure, mature technology and the like. Gas springs also have some drawbacks that are difficult to eliminate. 1. Service life of the gas spring: the service life of the conventional gas spring is only 2-3 ten thousand times, and the service life limit of the high-end gas spring is only about 3-6 ten thousand times. The problem of high cost is caused by using a high-end gas spring, and the defect of short service life exists in the conventional gas spring. 2. Safety problems of gas springs: the air spring has the sealing washer inefficacy and leads to leaking gas in the in-process of using, and the danger that the explosion takes place for quick lift etc. and the air spring suddenly became invalid and can lead to the arm body to droop fast, leads to breaking the equipment that the support supported, injures people by a crashing object etc.. 3. High-temperature environment: gas springs cannot be used in high temperature environments, and excessive temperatures can cause the gas spring to explode or otherwise fail. 4. Cost problem of gas spring support: due to the limitation of market selling price, most of the gas spring supports in the market currently use low-price gas springs, and various problems exist in the service life and the quality of the low-price gas springs.

A few similar brackets in the market adopt mechanical spring structures. The mechanical spring has the problem that the larger the compression distance is, the larger the elastic force is, so that the support lifting arm cannot realize free hovering. In order to realize the hovering of the lifting arm, most manufacturers add resistance inside the bracket to neutralize the increased elastic force of the spring, so as to realize the hovering function. However, this approach has a number of problems. 1. The lifting operation has poor hand feeling: particularly, the lifting operation needs to be performed by a large auxiliary force. 2. The resistance failure is caused by aging of the parts which increase the resistance in the use process, and the hovering function of the lifting arm is deteriorated and failed after the resistance failure. However, the mechanical spring has great advantages in both service life and cost, for example, the service life of the spring is longer, the service life of the conventional mechanical spring is 8-30 ten thousand times, the service life of the special mechanical spring can reach several thousand times, and the fatigue life of the engine valve spring can reach about 2000 ten thousand times. Compared with the gas spring, the gas spring has the advantages of lower production cost, more mature technology, stronger environment adaptability, no sudden failure of the mechanical spring as the gas spring, no explosion of the mechanical spring due to quick compression and the like. The biggest problem of the pendulum in our face is the structure.
