Extension seat body with space expansion function

Abstract

The invention discloses an extension seat body with a space expansion function. The extension seat body comprises two pipe seats, an outer telescopic seat, an inner telescopic seat, an outer locatingdevice and an inner locating device. The two pipe seats are symmetrically arranged. Each pipe seat is provided with an outer sliding hole and an inner sliding hole. The outer telescopic seat comprisesan outer transverse pipe and two outer telescopic pipes connected to the two ends of the outer transverse pipe, the outer telescopic seat is in an n shape overall, and the two outer telescopic pipesare telescopically arranged in the two outer sliding holes. The inner telescopic seat comprises an inner transverse pipe and two inner telescopic pipes connected to the two ends of the inner transverse pipe, the inner telescopic seat is in an n shape overall, and the two inner telescopic pipes are telescopically arranged in the two inner sliding holes. The outer locating device is arranged in theouter telescopic seat and can be driven by the outer transverse pipe to control the stretching length of the two outer telescopic pipes. The inner locating device is arranged in the inner telescopic seat and can be driven by the inner transverse pipe to control the stretching length of the two inner telescopic pipes. By the adoption of the above structure, the carrying capacity of carrying tools such as a luggage case and a cart can be greatly improved.

Description

technical field [0001] The present invention relates to the technical field of the structure of an extension seat, especially an extension of an expandable space that can extend the bottom of carrying tools such as suitcases and trolleys outward to expand additional carrying space to improve carrying capacity. seat body. Background technique [0002] The volume of the general luggage box is fixed, so its relative capacity is also fixed. Therefore, once the items carried are too many to be loaded, it is necessary to purchase additional luggage, suitcases or other loads for additional installation. , and then dragging, picking up, moving or consigning, so it will cause inconvenience for the user to carry and use. And in order to improve the above-mentioned problem, those skilled in the art have designed a kind of luggage case or suitcase or other casing or bag body (illustrated with auxiliary luggage case below) that can be increased or buckle and be located at original lugga...
