Abstract
The present disclosure provides an external clip-on fixture. The external clip-on fixture may include a support structure (1) and a first elastic member (2). The first elastic member (2) may be configured to sealedly wrap the support structure (1) and expand inward along a radial direction under actions of an inflating and deflating device. The external clip-on fixture of the present disclosure is small in size, light in weight, simple in structure, and low in cost. Fragile and soft objects with different sizes, regular or irregular external shapes, such as a column shape, a bottled shape, etc., may be stably clamped within a certain range without damaging the clamped objects.
Claims15
A fixture, comprising:
- an external clip-on fixture;
- and
- an auxiliary inner support arranged on the external clip-on fixture;
- wherein
- the external clip-on fixture includes:
- a support structure;
- a first elastic member, wherein the first elastic member is configured to sealedly wrap the support structure such that the first elastic member expands inward along a radial direction under actions of an inflating and deflating device;
- a sealing member being arranged on the support structure and tightly presses the first elastic member on the support structure through a fastener to ensure an airtightness between the first elastic member and the support structure in a mounting state;
- and
- an elastic member shape limiting structure being arranged on an outer wall of the first elastic member and being configured to change a shape of the first elastic member after expansion;
- wherein the elastic member shape limiting structure is a strip formed integrally with the sealing member, and the strip wraps a portion of the outer wall of the first elastic member along an axial direction in the mounting state:
- the auxiliary inner support includes a support member and a second elastic member;
- the second elastic member is configured to sealedly wrap a portion or all of an outside of the support member, such that a sealed cavity is formed between the second elastic member and the outside of the support member;
- and
- in a mounting or an in-use state, the sealed cavity is in communication with the inflating and deflating device, such that the second elastic member expands outward along the radial direction and assists the external clip-on fixture to clamp an object to be clamped from inside when the inflating and deflating device inflates gas into the sealed cavity;
- the external clip-on fixture surrounds the auxiliary inner support;
- wherein the first elastic member is located outside the object to be clamped, the second elastic member extends in the object to be clamped;
- the first elastic member expands inward along the radial direction to fit with an outer wall of the object to be clamped and clamp the object to be clamped from the outside, the second elastic member expands outward to fit with an inner wall of the object to be clamped and clamp the object to be clamped from the inside.
