Technical Field

[0001] This utility model belongs to the field of sports equipment technology, and more specifically, relates to a column adjustment device and a bench press frame. Background Technology

[0002] The bench press competition rack is a professional sports equipment used in the World Powerlifting Championships. Competitions typically include bench press and squat. In squat competitions, some competitors with wider shoulders need to place their hands on the outside of the main upright, requiring the upright to be tilted slightly inwards for better grip. However, for most competitors, the upright remains vertical without adjustment.

[0003] Current bench press competition racks generally only have height adjustment on the main upright, lacking incline adjustment. Even those that do offer incline adjustment typically use a downward-pressing mechanism, which is inflexible, complex, and inconvenient to use. Utility Model Content

[0032] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0033] Example 1

[0034] like Figure 1 and Figure 2 As shown, a column adjustment device includes a main column 10, a limiting column 2, and a reset pin 12. The limiting column 2 is fixedly connected to the base 1. The main column 10 is installed inside the limiting column 2, and there is a certain gap between the main column 10 and the limiting column 2. The bottom of the main column 10 is connected to the limiting column 2 through a connecting shaft 17, so that the main column 10 can tilt within a certain angle.

[0035] In this utility model, the column adjustment device can tilt the main columns 10 on both sides inward (e.g., Figure 3 and Figure 4 As shown, where Figure 3 It is in a vertical state. Figure 4 (In an inward-leaning position), this allows participants with broad shoulders to hold onto the outside of the main support column 10 during training or competition squats, making it easier for them to perform the competition.

[0036] In this embodiment, as Figure 2 As shown, a mounting hole 20 is provided on one side of the limiting post 2 for installing the reset pin 12. Specifically, the mounting hole 20 has a threaded structure, which is adapted to the threaded part on the reset pin 12 for fixation. When the reset pin 12 is damaged or needs to be replaced in other cases, the reset pin 12 can be directly unscrewed, which is convenient and quick.

[0037] In this embodiment, at least two positioning holes are provided on one side of the main column 10. For example... Figure 2 As shown, it includes a first positioning hole 19 and a second positioning hole 21, the positions of which correspond to the positions of the mounting holes 20. One of the positioning holes corresponds to the position when the main column 10 is in a vertical state, and the other positioning hole corresponds to the position when the main column is in an inclined state.

[0038] Preferably, the number of positioning holes is not limited to two; two or more holes can be used. Using multiple positioning holes allows for more flexible angle adjustments during tilting, making it more convenient for participants. The tilt angle of the main column can be adjusted between 0° and 15°; the more positioning holes there are, the more adjustable angles can be selected.

[0039] In this embodiment, as Figure 6 , Figure 7 and Figure 8 As shown, the reset pin 12 includes a cap 121, a threaded portion 122, and a pin portion 123.

In specific use, the reset pin 12 is first fixed to the threaded portion 122 with the mounting hole 20, and the pin portion 123 is inserted into a positioning hole, such as the second positioning hole 21, on the main column 10 at one of its vertical positions. At this time, the main column 10 is in a vertical state. When it is necessary to adjust the tilt of the main column 10, the pin portion 123 is pulled outward by holding the cap 121, and the main column 10 is manually tilted to the required angle. Then, the cap 121 is released, allowing the pin portion 123 to insert into the first positioning hole 19. At this time, the main column 10 is in a tilted state. Figure 2 and Figure 4 As shown.
