Abstract
Description
Technical Field
[0001] This utility model belongs to the field of leg flexion training technology, and in particular relates to a seat adjustment device for a seated leg flexion trainer. Background Technology
[0002] A seated leg curl trainer is a device used for leg curl training. The lower part of the seat usually has a mechanism for adjusting the seat position. Existing seat adjustment mechanisms for seated leg curl trainers include a fixed rod, a left sliding device on the left side of the fixed rod, and a right sliding device on the right side of the fixed rod. The left sliding device includes a left sliding shaft parallel to the fixed rod, and the left sliding shaft pulley slides within a left groove. The pulley is used for the left sliding plate to reciprocate along the left sliding shaft. This type of seat adjustment mechanism for seated leg curl trainers is adjusted through six limiting slots during use; therefore, the adjustment position is limited by these limiting slots, making the adjustment relatively restrictive. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a seat adjustment device for a seated leg curl trainer, which can adjust the position of the seat more flexibly.
[0004] This utility model is achieved through the following technical solution:
[0005] A seat adjustment device for a seated leg flexion trainer includes uprights and a seat base. A protrusion is integrally provided on one side of the upper end of each of the two uprights, and connecting columns are integrally provided on both sides of the upper end of the uprights. A translation limit block assembly is connected to the seat base. The translation limit block assembly includes a T-shaped limit block, and side limit blocks are integrally provided on both sides of the T-shaped limit block. Bolts and nuts are threaded into the interior of the T-shaped limit block, and a square steel rail is inserted into the interior of the T-shaped limit block. A rectangular groove is formed inside the square steel rail, and a limit rod is inserted into each of the side limit blocks. The side limit blocks and limit rods are slidably connected.
[0006] Preferably, the two seat base plates are respectively fixedly installed on the outer sides of the two side limiting blocks.
[0007] Preferably, the two ends of the two limiting rods are fixedly connected to the connecting columns located on both sides.
[0008] Preferably, the T-shaped limiting block is fixed to the square steel rail by bolts and nuts.
[0009] Preferably, the bolt and nut pass through the rectangular groove.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. In this utility model, the T-shaped limiting block, bolts and nuts, square steel rails, and rectangular grooves facilitate more flexible adjustment of the seat position.
[0012] 2. In this utility model, the side limiting block and the limiting rod are designed to limit the T-shaped limiting block. Attached Figure Description

[0017] The present invention will now be described in detail with reference to the accompanying drawings, as shown below. Figure 1 and attached Figure 2 As shown, a seat adjustment device for a seated leg curl trainer includes uprights 1 and a seat base 4. A protrusion 2 is integrally provided on one side of the upper end of each of the two uprights 1, and connecting posts 3 are integrally provided on both sides of the upper end of the uprights 1. A translation limit block assembly 5 is connected to the seat base 4. The translation limit block assembly 5 includes a T-shaped limit block 51, and side limit blocks 52 are integrally provided on both sides of the T-shaped limit block 51. Bolts and nuts 53 are threadedly connected inside the T-shaped limit block 51, and a [missing information - likely a device or component] is inserted inside the T-shaped limit block 51. When adjusting the seat position, the T-shaped limiting block 51 can move along the square steel track 54. The square steel track 54 has a rectangular groove 55 inside. The T-shaped limiting block 51 is fixed to the square steel track 54 by bolts and nuts 53, which pass through the rectangular groove 55. Each side limiting block 52 is inserted with a limiting rod 56. The side limiting block 52 and the limiting rod 56 are slidably connected. The side limiting block 52 and the limiting rod 56 play the role of limiting the T-shaped limiting block 51.
[0018] In this embodiment, specifically, the two seat base plates 4 are respectively fixedly installed on the outer sides of the two side limiting blocks 52.
[0019] In this embodiment, specifically, the two ends of the two limiting rods 56 are fixedly connected to the connecting posts 3 located on both sides.
[0020] Working principle
[0021] In this utility model, when connecting the seat adjustment device to the seat of the seated leg flexion trainer, the seat base plate 4 is fixed to the seat. The user loosens the bolts and nuts 53 and slides the T-shaped limiting block 51 along the square steel track 54. At this time, the side limiting block 52 slides along the limiting rod 56, which plays a limiting role on the T-shaped limiting block 51. After adjustment, the bolts and nuts 53 are fixed, thereby adjusting the position of the seat base plate 4 and realizing the function of continuous adjustment of the seat position.
[0022] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution of this utility model, falls within the protection scope of this utility model.
