Description

Technical Field

[0001] This utility model relates to the field of fitness equipment, specifically an adjustable fitness gantry frame. Background Technology

[0002] A powerlifting machine, a common multi-strength training tool, typically includes the main frame, base, adjustable support, and height-adjustable sliders with hanging rings (or buckles) that slide on the support. These sliders are used to suspend different training handles and are connected to the weight system via ropes. Their height needs to be adjusted according to the trainee's height and training movements.

[0003] The slider has a locking structure on its side (usually including a locking pin, end plate, and spring). The locking pin can be selectively inserted into a locking hole on the slide groove to fix the slider's height. When the height needs to be adjusted, the operator must manually pull the locking pin outward to disengage it from the locking hole, then manually push the slider along the slide groove to the desired height, and then release the locking pin so that it is inserted into the corresponding locking hole under the action of the spring to complete the fixation. When adjusting the slider upward, the operator usually needs to hold the slider with one hand and pull the locking pin outward to disengage it with the other hand, while also pushing the slider upward. Because it is difficult to ensure that the force applied manually is strictly vertical and upward, it is easy to generate an upward component force. This horizontal component force forces the slider (especially its protruding part) to press tightly against the inner wall of the slide groove of the adjusting support, generating significant frictional resistance. This makes pushing the slider upward laborious and sluggish, and the adjustment process is not smooth and convenient, especially at high positions or when the slider bears a certain weight. The smoothness of the adjustment largely depends on the operator's force application skills, resulting in a poor user experience. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model discloses an easily adjustable fitness gantry frame. The technical solution adopted includes a gantry frame, a base, adjusting pillars, left and right side slides, locking holes, front and rear side slides, and a height adjustment slider. The gantry frame is a common fitness gantry frame. The adjusting pillars on both sides are fixed to the base. The sides of the adjusting pillars are respectively opened with left and right side slides and front and rear side slides. Several through locking holes are distributed in the left and right side slides. The inner wall of the height adjustment slider for setting the hanging ring has a protruding part, which is respectively fitted into the left and right side slides and the front and rear side slides. The right side of the height adjustment slider has a through hole, and a locking structure is set at the through hole to fix the height of the height adjustment slider in conjunction with the locking hole. All of the above are existing... Some conventional techniques are commonly found in fitness equipment. The installation methods for the buckles used to mount different handles on a gantry frame, as well as the connection and installation methods between the buckles and the counterweight ends, are existing technologies in this field. This application's technical solution mainly focuses on structural improvements to the height adjustment block where the buckles are located, aiming to achieve convenient adjustment of the height adjustment block. Its features include: an auxiliary support column, a front through slot, a right through slot, a movable shaft, a connecting rod, a stabilizing shaft, a pressure plate, a rope, a left guide shaft, a right guide shaft, and a fixed protective plate. The auxiliary support column is fixed to the base on the left side of the base, with a front through slot in its front-to-back direction and a right through slot on its right side. A stabilizing shaft is vertically fixed at the center of the front through slot, and a through hole is opened in the middle of the movable shaft. The through-hole sleeve is fitted onto the stabilizing shaft, with both sides contacting the inner wall of the front through-groove. A one-piece connecting rod is integrally formed on the right side of the movable shaft, extending from the right through-groove and having a pressure plate fixed at its extended end. Two one-piece fixed protective plates are integrally formed on the top of both the adjusting support column and the auxiliary support column. The left and right guide shafts are fixed between the left and right sets of fixed protective plates, respectively. One end of the rope is fixed to the movable shaft, and the other end passes through the through-hole at the top of the movable shaft, passes over the left and right guide shafts, and then extends through the through-hole between the adjusting support column and the front and rear side slide grooves, and is fixedly connected to the upper surface of the protruding part of the height adjusting slider. Traditional gantry cranes require one hand to hold the height adjusting slider and the other hand to pull outwards to lock the structure when adjusting the height. To lower the height adjustment slider, first release the locking mechanism and then push it up with the other hand. To lower the slider, manually release the locking mechanism; it will then descend under its own weight. However, during lifting, manual pushing cannot guarantee a vertical upward force; there may be an upward force, and the resulting horizontal component can cause the slider to press against the side of the adjustment column, creating friction and resistance, making upward pushing inconvenient. This solution addresses this by allowing the left hand to directly press down on the moving plate and pull the rope, which, after passing through a guide, pulls the height adjustment slider upward. This method ensures the upward force is vertically upward, avoiding increased lateral friction and thus facilitating adjustment.

[0005] As a preferred technical solution of this utility model, the locking structure includes a locking insert shaft, an end plate and a spring. The right side of the height adjustment slider has an opening, and the locking insert shaft passes through the opening and is inserted into the locking hole. The outer end of the locking insert shaft is fixed to the end plate. The left side of the end plate is connected to the recessed groove at the opening of the end plate by a spring. The spring is sleeved on the outside of the locking insert shaft.

[0006] As a preferred technical solution of this utility model, several finger rings are evenly distributed on the outer side of the end plate, so that the fingers can be inserted into the finger rings for convenient operation when the end plate is pulled outward.

[0007] As a preferred technical solution of this utility model, the pressure plate is provided with several anti-slip grooves.

[0008] As a preferred technical solution of this utility model, the pressure plate is covered with a sponge pad, the rope is made of nylon rope, and its outer wall is covered with a rubber sheath.

[0009] The beneficial effects of this utility model are as follows: By pressing down the pressure plate, the movable shaft moves downward and pulls the rope. The rope passes around the left and right guide shafts, and finally applies a strict vertical upward traction force to the height adjustment slider. This completely avoids the horizontal component force generated by the oblique force when manually pushing upward, thus eliminating the additional frictional resistance between the protruding part of the slider and the inner wall of the adjustment support groove. Users only need to press down the pressure plate with one hand to achieve a smooth and effortless rise of the slider, greatly improving the convenience of operation. Attached Figure Description

The user then presses down on the pressure plate with their left hand (the surface of the pressure plate can be provided with anti-slip grooves or covered with sponge pads to improve operating comfort). The movable shaft moves down along the stabilizing shaft, and the rope is pulled. The left and right guide shafts act as fixed pulleys, ultimately converting the direction of the rope tension into a vertical downward force (acting on the end of the rope). According to the pulley principle, when this vertical downward force is transmitted to the slider, it is equivalent to applying a vertical upward lifting force to the slider. Under the action of the vertical upward force transmitted by the rope, the height adjustment slider rises smoothly with little or no friction along the left and right side slides and front and rear side slides of the adjusting support (through the cooperation of their inner wall protrusions).
