Embodiment Construction

[0053] see Figure 1~3 As shown, the extended seat body showing the expandable space of the present invention includes two pipe seats 10, an outer telescopic seat 20, an inner telescopic seat 30, an outer positioning device 40 and an inner positioning device 50, wherein:

[0054]The two tube bases 10 are arranged in parallel and symmetrically. Each tube base 10 has an outer sliding hole 11 located on the opposite side and an inner sliding hole 12 located on the opposite inner side. The outer sliding hole 11 and the inner sliding hole 12 The opposite end surfaces of the opposite end faces respectively form an opening shape, and the hole wall on the side of the outer sliding hole 11 far away from the inner sliding hole 12 is provided with a plurality of outer positioning holes 13 at intervals, and the inner sliding hole 12 is close to one side of the outer sliding hole 11. A plurality of inner positioning holes 14 are arranged at intervals on the side hole walls.

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...
