Interior support type clamp based on gasbag

Abstract

The invention provides an interior support type clamp based on a gasbag. The interior support type clamp comprises a gas path, a supporting part, a gasbag and a connecting part, wherein the gasbag ismade of a high-elasticity material, at least coats partial outer side of the supporting part, and defines an inner cavity with the supporting part; at least one end opening of the gas path penetratesthrough the supporting part and is connected with the inner cavity; and the connecting part is connected with the supporting part for external connection of the interior support type clamp. The clampwith the gasbag extends into the inner cavity of an object, the high-elasticity gasbag expands to fit to the inner surface of the object, the high-elasticity gasbag and the inner surface of the objectare conformal, local stress concentration is not generated, and the inner surface of the object is not liable to damage, so that the object can be stably and safely clamped without damages.

Description

technical field [0001] The present invention relates to the technical field of mechanical clamps, and more particularly, relates to an internal support clamp based on an airbag. Background technique [0002] In industrial production and daily life, it is necessary to pick up certain objects. Sometimes, because it is inconvenient to directly contact its outer surface, it can only be picked up by supporting its inner wall from the inside. And some objects, because of reasons such as thin wall thickness, weak strength or easily damaged inner surface, cannot use metal or other rigid fixtures for internal support clamping, otherwise it may cause damage to the object. Or for some objects, the internal space is small or the outline is complex, and the custom-made rigid fixture is expensive and cannot be applied to other objects at the same time. And if the design is improper, it may also cause poor clamping stability and easy to fall off. [0003] Therefore, a technology is neede...

[0002] In industrial production and daily life, it is necessary to pick up certain objects. Sometimes, because it is inconvenient to directly contact its outer surface, it can only be picked up by supporting its inner wall from the inside.

However, some objects cannot be clamped with metal or other rigid fixtures for internal support due to thin wall thickness, weak strength or easy damage to the inner surface, otherwise the object may be damaged

Or for some objects, the internal space is small or the outline is complex, and the custom-made rigid fixture is expensive and cannot be applied to other objects at the same time

And if the design is improper, it may also cause poor clamping stability and easy to fall off
