[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0026] The utility model discloses a strength-type lifting training device, such as Figure 1 As shown, it includes a main frame 02, the bottom of which is fixed to the ground, and lifting racks are provided on both sides of the top. Adjustable counterweight units 01 are provided on the sides of the lifting racks, and the adjustable counterweight units 01 are located on the outside of the lifting racks and in the middle of the top of the lifting racks. The head ends of the lifting racks on both sides of the main frame 02 are fixed with lifting rods 07, and the tail ends are hinged to the top of the main frame 02. An L-shaped support rod 04 is fixed below the tail end of the lifting rod rack, and the L-shaped support rod 04 is fixedly connected to the main frame 03 through the crossbeam 03; the L-shaped support rod 04 is inverted and provided on one side of the tail end of the lifting rack to provide training space. The bottom of the L-shaped support rod 04 is buried in the ground, which can support the main frame 02 and improve the overall stability of the equipment. The top is fixedly connected to the crossbeam 03. The lifting rod 07 includes a lifting rod body with a downwardly curved "7" shape. A protective sleeve made of rubber, sponge, or foam material is provided on the lifting rod body. The sleeve provides protection for the trainee while also providing a certain degree of comfort. During use, the trainee stands in front of the main frame and faces the main frame 02. They grasp the lifting rod 07 with both hands and perform a reciprocating upward lifting motion. The lifting frame swings up and down around the limiting spindle 22 as the trainee squats and stands.

[0027] As a specific implementation method, Figure 2As shown, the adjustable counterweight unit 01 includes a U-shaped counterweight rod 11 fixed on the side of the sitting and lifting frame and arranged perpendicularly thereto, a sliding rod 12 is fixed on the rod body at both ends of the U-shaped counterweight rod 11, and a plurality of counterweight plates 13 are slidably arranged on the sliding rod 12, and are axially limited by a limit assembly and the sliding rod 12.

[0028] The U-shaped counterweight rod 11 limits the movement range of the counterweight plate 13, so that it cannot leave the main frame 02 and can only move on the U-shaped counterweight rod 11. Several counterweight plates 13 can be reasonably distributed according to the strength of different groups. When the required counterweight is larger, the rear counterweight plate 13 can be appropriately moved to the front. When the required counterweight is smaller, the front counterweight plate 13 can be appropriately moved to the back.

[0029] As a specific implementation method, Figure 3-5 As shown, the limiting assembly includes limiting protrusions 122 and annular rings 132. Several limiting protrusions 122 are arranged perpendicular to the axis of the slide bar 12 and spaced apart along its axial direction. Annular rings 132 are fixedly mounted on both ends of each weight plate 13. An annular limiting groove 134, which is adapted to fit the limiting protrusion 122, is formed between the annular rings 132 on both ends of each weight plate 13. Each annular ring 132 is provided with a groove 133 adapted to fit the limiting protrusion 122. The grooves 133 of the two annular rings 132 on the same weight plate 13 are symmetrically arranged relative to the weight plate 13. The distance between two adjacent protrusions is consistent with the distance between the limiting grooves 134 on two adjacent weight plates 13. The slide bar 12 includes a tubular slide bar body 121, to which several limiting protrusions 122 are fixedly mounted. The weight plate 13 includes a weight plate body 131 , and an annular ring 132 is fixedly mounted on both end surfaces of the weight plate body 131 via pins 00 .

[0030] During training, the limiting protrusion 122 is located in the limiting groove 134 between the two annular rings 132 on the counterweight plate 13, and the counterweight plate 13 is stuck by the limiting protrusion 122, and the limiting protrusion 122 limits the counterweight plate 13; when it is necessary to adjust the position of the counterweight plate 13 at both ends of the U-shaped counterweight rod 11, the counterweight plate 13 is rotated to make the groove 133 on the annular ring 132 rotate to the position of the limiting protrusion 122, and the restriction of the limiting protrusion 122 is released, and the counterweight plate 13 can be moved along the sliding rod 12 until it passes the middle position of the U-shaped counterweight rod 11 and reaches the other end, and then the counterweight plate 13 is limited according to the above reverse steps to achieve weight adjustment. This structure can achieve adjustable position of the weight plate 13, and thus achieve adjustable weight for equipment training. Through the limiting structure of the limiting protrusion 122 and the limiting groove 134, the position of the weight plate 13 relative to the U-shaped weight rod 11 can be relatively fixed, preventing the weight plate 13 from being displaced during training and causing weight changes.

[0031] In indoor pull-up trainers, the weight plates 13 in traditional technology are often placed on a shelf or on the ground. When adjusting the weight, they need to be moved around. When not in use, the scattered weight plates 13 need to be sorted on the storage rack. The weight plates 13 in the utility model are limited to the U-shaped weight rod, and there is no need to carry and sort the weight plates 13 back and forth like in traditional technology. At the same time, when used outdoors, the U-shaped weight rod 11 can also play an anti-theft role.

[0032] As a specific implementation method, Figure 1 As shown, the lifting frame includes an upper arm 09, a forearm 08, and a connecting arm 10. The upper arm 09 and the forearm 08 are fixedly connected at their head ends, the middle of the forearm 08 is fixedly connected to the head end of the connecting arm 10, a lifting rod 07 is fixed to the bottom of the forearm 08, and the tail ends of the upper arm 09 and the connecting arm 10 are rotatably connected to the hinge seat at the top of the main frame 02 via a limiting main shaft 22. The connecting arm 10 forms a stable structure for the upper arm 09 and the forearm 08.

[0033] As a specific implementation method, Figure 1 As shown, the main frame 02 includes two columns, which are fixedly connected by a crossbeam 03. A reference rod 21 is fixedly mounted parallel to the bottom of the crossbeam 03. The ends of the reference rod 21 are fixedly connected to the two columns, and the hinge seat is fixed to the top of the column. The rod body of the U-shaped counterweight rod 11 at both ends passes through the limit shaft 123 and is vertically fixedly connected to the upper arm 09 of the lifting frame via a pin 00. The limit shaft 123 is vertically fixedly connected to the upper arm 09 of the lifting frame. The tops of the two columns are tilted at a certain angle. The bottoms of the columns and the bottoms of the L-shaped support rods 04 are buried below the ground, with the reference rod 21 representing the horizon.

[0034] In summary, the utility model solves the problem in traditional technology that the weight of the lifting trainer cannot be adjusted and cannot meet the usage needs of different groups, and is suitable for the field of sports equipment technology.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
