Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a multifunctional bench press rack. Background Technology

[0002] The bench press rack is a commonly used strength training equipment. Traditional bench press racks consist of a frame and a bench. To ensure scientific training for the user and prevent displacement that could lead to imbalance, the bench and frame are usually fixedly connected, often by screws or welding. However, this structure is not conducive to the transportation and storage of bench press racks. Moreover, they have limited functionality and cannot meet the user's training needs, and they take up a lot of space. Therefore, there is a need to design a multifunctional bench that is easy to assemble, disassemble, transport, or store. Utility Model Content

The height of the lifting column within the movable cavity is adjusted by engaging the pin holes. Two protective frames are symmetrically arranged below the barbell rack. The base has two symmetrically arranged locking seats. The bench has a bottom beam with locking holes at both ends corresponding to the two locking seats. The bottom beam is installed with the two locking seats, and the locking holes are locked by locking components.

[0006] Furthermore, the base is provided with a column base for installing the column. The column base has an upward-facing column groove that is adapted to the column. The column is inserted into the column groove. The side wall of the column is provided with a C-shaped locking seat. The column base is provided with a locking rod. The locking rod is inserted into the C-shaped locking seat. The locking rod and the C-shaped locking seat are provided with aligned insertion holes and are fixed by a pin.

[0007] Furthermore, the column base is provided with a fixing seat on the side facing the protective frame body, the protective frame body is provided with a fixing plate, the fixing plate is provided with fixing holes that align with the fixing seat, the fixing plate is fitted to the protective frame body, and is fixed by bolts screwed into the fixing holes.

[0008] Furthermore, the protective frame includes an inverted T-shaped base frame and a T-shaped top frame. The inverted T-shaped base frame is fixedly connected to the fixing plate and has an upward-facing telescopic cavity. The T-shaped top frame is inserted into the telescopic cavity, and its height can be adjusted by using multiple insertion holes and pins.

[0009] Furthermore, the T-shaped top frame is provided with two triangular stops at each end to prevent the barbell from falling.

[0010] Furthermore, the base is provided with two symmetrically arranged stabilizing tubes on both sides to increase structural stability.

[0011] Furthermore, the bottom beam is provided with two symmetrically arranged pedals at the top and two symmetrically arranged rollers at the bottom.

[0012] Furthermore, the base is also provided with a control component for controlling the lifting column. The control component includes a support column, an adjusting joint, and a control rod. The base is provided with a socket, and the support column is inserted into the socket. A fixing rod is provided on the side wall of the column. The adjusting joint is rotatably mounted on the fixing rod via a pivot, and its two ends are rotatably mounted to the support column and the control rod, respectively. The end of the control rod facing the lifting column is provided with a C-shaped claw. The C-shaped claw is provided with a locking slot that engages with a pin. By rotating the control rod on the adjusting joint, the C-shaped claw, the pin, and the lifting column move up and down along the column.

[0013] Furthermore, the adjusting joint is composed of two rotating plates that are rotatably mounted together. The rotating plates, the column, the control rod, and the fixing rod are all provided with rotating holes that are in opposite positions, and are rotatably mounted by a rotating shaft.

[0014] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:
