[0024] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the present utility model, and are not used to limit the present utility model.

[0025] The present utility model discloses a power type rowing trainer, as Figure 1 shown, which includes a main frame 02, the bottom of the main frame 02 is fixedly provided on the ground, and push-pull frames are provided on both sides of the top. The push-pull frames include a forearm 09 and an upper arm 08. The forearm 09 is horizontally arranged, the upper arm 08 is vertically arranged, and an adjustable counterweight unit 01 is horizontally arranged on the side of the forearm 09. The tail end of the forearm 09 and the bottom end of the upper arm 08 are fixedly connected and are hinged to the top of the main frame 02 through a hinge seat. A rowing handle 07 is provided at the top end of the upper arm 08. A cross beam 03 and a seat frame 04 are provided at a position close to the top of the main frame 02. The seat frame 04 is fixedly connected to the main frame 02 through the cross beam 03. A seat board 05 and a backrest board 06 are provided on the seat frame 04. The adjustable counterweight unit 01 is located outside the forearm 09. The seat board 05 and the seat frame 04 are arranged on one side of the main frame 02 away from the push-pull frame. The bottom of the seat frame 04 is buried below the ground, which can support the main frame 02 and improve the overall stability of the equipment. When in use, the training personnel sit on the seat board 05, with their backs closely attached to the backrest board 06, and then hold the rowing handle 07 with both hands and repeatedly pull the push-pull frame backward, so that the push-pull frame swings up and down with the limit main shaft 22 as the center.

[0026] As a specific implementation manner, as Figure 3 shown, the adjustable counterweight unit 01 includes a U-shaped counterweight rod 11 fixedly provided on the side of the forearm 09 and perpendicular to it. Slide rods 12 are fixedly provided on the rod bodies at both ends of the U-shaped counterweight rod 11. A plurality of counterweight plates 13 are slidably arranged on the slide rods 12 and are axially limited to the slide rods 12 through a limit assembly.

[0027] The U-shaped counterweight rod 11 limits the moving 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.

[0028] As a specific implementation method, Figures 4 - 5 As shown, the limiting assembly includes a limiting protrusion 122 and an annular ring 132. A plurality of limiting protrusions 122 are arranged perpendicular to the axis of the slide bar 12 and are arranged at intervals along the axial direction thereof. An annular ring 132 is fixedly provided on both end surfaces of each weight plate 13. A limiting groove 134 of an annular structure adapted to the limiting protrusion 122 is formed between the annular rings 132 on both end surfaces of each weight plate 13. A groove 133 adapted to the limiting protrusion 122 is provided on the annular ring 132. The groove 133 of the annular ring 132 on the same weight plate 13 is 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 slide bar body 121 of a tubular structure. A plurality of limiting protrusions 122 are fixedly provided on the slide bar body 121. The weight plate 13 comprises a weight plate body 131 , and an annular ring 132 is fixedly mounted on both end surfaces of the weight plate body 131 by means of pins 00 .

[0029] During training, the limiting protrusion 122 is located in the limiting groove 134 between the two annular rings 132 on the weight plate 13, and the weight plate 13 is stuck by the limiting protrusion 122, and the limiting protrusion 122 limits the weight plate 13; when it is necessary to adjust the position of the weight plate 13 at both ends of the U-shaped counterweight rod 11, the weight 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 weight 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 weight 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 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 shifting during training and causing weight changes.

[0030] The counterweight plates 13 in the conventional technology are often placed on a storage rack or on the ground. When adjusting the counterweight, they need to be moved around. When not in use, the scattered counterweight plates 13 need to be sorted on the storage rack. The counterweight plates 13 in the utility model are limited to the U-shaped counterweight rod, and there is no need to carry and sort the counterweight plates 13 back and forth like in the conventional technology. At the same time, when used outdoors, the U-shaped counterweight rod 11 can also play an anti-theft role.

[0031] As a specific embodiment, as Figure 1 shown, the main frame 02 includes two columns, which are fixedly connected by a cross beam 03 at the top. The hinge seat is fixedly arranged at the top of the column. The rod bodies at both ends of the U-shaped counterweight rod 11 pass through the limit shaft 123 and are vertically and fixedly connected to the upper arm 09 of the push-pull frame through a pin 00. The limit shaft 123 is vertically and fixedly connected to the upper arm 09 of the push-pull frame. The bottoms of the columns and the bottom of the seat frame 04 are buried below the ground.

[0032] In summary, the utility model solves the problem that the outdoor rowing trainer commonly used in the traditional technology has non-adjustable load and cannot meet the usage requirements of different training populations, and is applicable to the technical field of sports equipment.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the scope of protection of the claims of the present utility model.
