Domestic sucker punching sandbag

Abstract

The invention provides a domestic sucker punching sandbag, and relates to the field of sports equipment. According to the domestic sucker punching sandbag, an airbag is formed in the inner cavity of arubber pipe; the bottom of the airbag is connected with the top of the sucker through a conductor pipe; the top of the airbag is connected with a branch pipe; the bottom of the inner cavity of the sandbag outer shell is connected with a suction pipe; a piston is mounted in the inner cavity of the suction pipe; a transmission rod is connected to the top of the piston; hollow pipes are arranged inthe middle of the inner cavity of the sandbag outer shell; the bottom of the hollow pipes are connected with the top of the suction pipe; sliding blocks are connected to the inner sides of the slidinggrooves from top to bottom at equal interval in a sliding manner; and small rods are connected to the outer side of the transmission rod at equal interval, and one side of each the small rod away from the transmission rod is connected with the sliding blocks. According to the domestic sucker punching sandbag, supporting rods drive the transmission rod to move upwards obliquely, so that the transmission rod can drive the piston to move upwards, and gas in the sucker, the air bag and the suction pipe is contracted, so that the sucker can generate greater suction force when the sandbag is hit.

Description

technical field [0001] The invention relates to the technical field of sports equipment, in particular to a boxing sandbag with suction cups for household use. Background technique [0002] Boxing sandbags are a kind of fitness equipment for modern people to exercise and release pressure. The existing sandbags are generally divided into two types, one is a hanging sandbag, and the other is a column-type sandbag. To facilitate the installation and movement of sandbags, column-type sandbags are generally used. [0003] In the invention of this solution, the applicant found after searching that a Chinese patent disclosed a "fitness sandbag", and its application number is "201710734236.1". The performance and safety are better, the diameter of the sandbag is larger than the diameter of the base, the striker can choose the sandbag to hit at a closer distance, but in order to ensure the stability of the sandbag during use, it is necessary to use the weight of the mount to ensure ...

[0003] In the invention of this solution, the applicant found after searching that a Chinese patent disclosed a "fitness sandbag", and its application number is "201710734236.1". The performance and safety are better, the diameter of the sandbag is larger than the diameter of the base, the striker can choose the sandbag to hit at a closer distance, but in order to ensure the stability of the sandbag during use, it is necessary to use the weight of the mount to ensure that the sandbag is under impact The heavy weight of the sandbag will make the sandbag inconvenient in many situations, for example, the sandbag will be inconvenient when transporting, and the sandbag will be very bulky when pushing the sandbag to move

[0004] Refer to "A Base and Its Sandbag", the application number is "201620512380.1", which discloses a suction cup sandbag, which uses a suction cup to fix the sandbag, but after the sandbag is installed, the sandbag is easy to The installation is unstable, and after the sandbag is installed through the suction cup, the sandbag is inconvenient to move
