Technical Field

[0001] The utility model relates to the technical field of fitness equipment connecting components, in particular to a connecting and adjusting mechanism for adjusting the height of a sandbag. Background Art

[0002] Sandbags are commonly used fitness equipment in boxing. Sandbags can help boxers exercise their punching strength and punching posture. Nowadays, most sandbags are vertical and suspended sandbags. The vertical structure is usually formed by inserting the sandbag body on the base to form a whole, so that the feedback of the sandbag during the hitting process is usually regular. However, the situations encountered by boxers in actual boxing are often changing rapidly. Therefore, vertical sandbags are difficult to meet the actual training effect. Suspended sandbags can solve the above needs. However, since each boxer has a different height, the suspended sandbag is fixed and single, and it is difficult to meet the use needs of boxers of different heights. Therefore, a connection adjustment mechanism for adjusting the height of the sandbag is proposed. Summary of the invention

[0008] As a further preferred embodiment of the technical solution: the bottom adjustment assembly comprises a "U"-shaped fixing plate for receiving the component, and four first connecting plates are symmetrically hinged to each other through pins inside the "U"-shaped fixing plate;

[0009] Wherein, one end of the four first connecting plates away from the "U"-shaped fixing plate is respectively installed on four installation columns.

[0010] As a further preferred embodiment of the present technical solution: a "U"-shaped fixing plate is provided to receive the first connecting plate, and at the same time, the second connecting plate is installed on the mounting column, so as to ensure the stable operation of the bottom adjusting assembly.

The "L"-shaped rotating rod makes it convenient for staff to apply external force to drive the threaded rod to operate, and the grip sleeve can effectively prevent slipping when driven by external force.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The threaded rod of the utility model drives two adjustment blocks to adjust in opposite directions synchronously by using the bidirectional threads on the threaded rod under the action of external force, and drives the connected bottom adjustment component and top adjustment component to run and adjust under the action of the mounting column, so as to achieve the effect of adjusting the height of the sandbag, thereby effectively solving the problem that the traditional suspended sandbag has a single fixation and is difficult to meet the use needs of boxers of different heights;
