Gas tank device in barking stopper

Abstract

The gas tank device comprises a gas tank and an electromagnetic valve assembly, the gas tank is provided with a base, a fixing hole is formed in the base, an expansion sleeve is arranged in the fixing hole, the expansion sleeve is composed of a connecting ring and a plurality of expansion pieces annularly arranged in the axis direction of the connecting ring, the tail ends of the expansion pieces are all connected with the connecting ring, and the electromagnetic valve assembly is arranged on the connecting ring. The initial ends of the multiple expansion pieces are all arranged in a gathering mode in the axis direction of the connecting ring and form expansion openings, and the connecting ring is provided with penetrating holes which are used for being in threaded fit with an external embedded bolt and expanding the expansion pieces to enable the multiple expansion pieces to be in expansion fit with the inner circumferential wall of the fixing hole when the embedded bolt is screwed in. The expansion piece is provided with a limiting piece used for preventing the expansion piece from being separated from the fixing hole in the axis direction of the fixing hole when the expansion piece is in expansion fit with the fixing hole, and the connecting ring is provided with a fixing piece used for preventing the connecting ring from being separated from the fixing hole. The barking stopper solves the problem that a gas tank device in a barking stopper in the prior art is not stably mounted and is easy to loosen or shake when a dog moves.

Claims

1. A gas tank device in a barking control device, comprising a gas tank and a solenoid valve assembly matched with the gas tank, characterized in that: The bottom of the gas tank is provided with a base, the base is provided with a fixing hole corresponding to the position of the embedded bolt on the external bark arrester housing, and a tensioning sleeve is provided in the fixing hole, and the tensioning sleeve is composed of a connecting ring and a plurality of tensioning sheets circumferentially provided along the axial direction of the connecting ring, the tail ends of the plurality of tensioning sheets are connected to the connecting ring, the plurality of tensioning sheets are made of elastic material, the starting ends of the plurality of tensioning sheets are gathered toward the axial direction of the connecting ring and formed with tensioning openings, the connecting ring is provided with a through hole for cooperating with the external embedded bolt thread and for spreading the tensioning sheet when the embedded bolt is screwed in so that the plurality of tensioning sheets are tensioned and matched with the inner circumferential wall of the fixing hole, the tensioning sheet is provided with a limiting member for preventing the tensioning sheet from detaching from the fixing hole along the axial direction of the fixing hole when the tensioning sheet is tensioned and matched with the fixing hole, and the connecting ring is provided with a fixing member for preventing the connecting ring from detaching from the fixing hole along the radial direction of the fixing hole.

2. The gas tank device in the barking control device according to claim 1, characterized in that: The inner circumferential wall of the fixing hole is circumferentially provided with a limiting groove, the starting end of the expansion piece is bent toward the limiting groove to form a limiting piece, and a plurality of the limiting pieces are plug-in-matched with the limiting groove, and the limiting piece is a limiting member.

3. The gas tank device in the barking control device according to claim 2, characterized in that: The radial cross section of each of the limiting pieces is triangular, the radial cross section of the limiting piece is matched with the radial cross section of the limiting groove, and the inner wall of the limiting piece is abutted and matched with the inner wall of the limiting groove.

4. The gas tank device in the barking control device according to claim 1, characterized in that: A fixing groove is provided on the outer peripheral wall of the base in an annular direction corresponding to the position of the fixing hole.
