Adapter structure for a gas fuel bottle

摘要

An adapter structure for a gas fuel bottle cooperates with a bottle and is connected with a power tool. The adapter structure contains a body connecting with the bottle, a gas sealing assembly fixed inside the body, a fixing member cooperating with a spherical connecting portion of the power tool, and a plurality of elastic retaining members secured on the fixing member. Each elastic retaining member forms an elastic spreading mouth, and a diameter of the elastic spreading mouth is normally smaller than that of the spherical connecting portion, the elastic spreading mouth is pressed to expand so that the spherical connecting portion slides into or disengages from the opening. Each of the elastic retaining members is separated from the fixing member, whereby the adapter structure benefits easy die sinking and assembly.

1. An adapter structure for a gas fuel bottle, connected with a spherical connecting portion (21) of a power tool (20) along an assembling direction that the adapter structure moves toward the spherical connecting portion (21) of the power tool (20), the adapter structure comprising:
a body (30) connecting with a bottle (10), the body (30) including a gas channel (31) coupled with an output end (11) of the bottle (10); a gas sealing assembly (40) mounted in the gas channel (31), the gas sealing assembly (40) respectively connecting with the output end (11) and the spherical connecting portion (21); a fixing member (50) located at the top of the body (30) for fastening the spherical connecting portion (21), the fixing member (50) including an opening (51) communicating with the gas channel (31) and used to receive the spherical connecting portion (21), a diameter of the opening (51) being larger than that of the spherical connecting portion (21), the fixing member (50) also including a plurality of engaging orifices (52) running through an inner wall and an outer wall of the fixing member (50) and communicating with the gas channel (31) and the opening (51), each of the plurality of engaging orifices (52) including an upper engaging surface and a lower engaging surface that are perpendicular to the assembling direction and parallel with each other; a plurality of elastic retaining members (60) separably mounted on the fixing member (50) and correspondingly arranged in the plurality of engaging orifices (52), each elastic retaining member (60) including an abutting portion (61) and two resilient legs (62) extending from the abutting portion (61), the two resilient legs (62) being secured on the outer wall of the fixing member (50), and the abutting portions (61) extending into the opening (51) via the engaging orifices (52) and abutting the upper engaging surface and the lower engaging surface to restrain the elastic retaining member (60) from moving along the assembling direction, the plurality of elastic retaining members (60) forming an elastic spreading mouth corresponding to the opening (51), and a diameter of the elastic spreading mouth being smaller than that of the spherical connecting portion (21), the elastic spreading mouth being pressed to expand so that the spherical connecting portion (21) slides into or disengages from the opening (51).
