[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 used to limit the present invention.

[0026] The utility model discloses a strength type sit-and-push training device, such as Figure 1 As shown, it includes a main frame 02, the bottom of which is fixed to the ground, and seat push frames are provided on both sides of the top. An adjustable counterweight unit 01 is provided on the side of the seat push frame, and the adjustable counterweight unit 01 is located on the outside of the seat push frame and in the middle of the top of the seat push frame. A seat push rod 07 is fixed at the head end of the seat push frame, and the tail end of the seat push frame is hinged to the top of the main frame 02, and an L-shaped support rod 04 is fixed below the seat push rod 07. The L-shaped support rod 04 is fixedly connected to the main frame 02 through a cross beam 03, and a seat plate 05 and a backrest plate 06 are provided on the top of the L-shaped support rod 04; the seat plate 05 and the L-shaped support rod 04 are arranged on one side of the head end of the seat push frame and are located below the head end of the seat push frame. The L-shaped support rod 04 is inverted, and its bottom 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 cross beam 03. When in use, the trainee sits on the seat board 05 with his back close to the backrest board 06, holds the seat push rod 07 with both hands, and repeatedly pushes up and down the seat push frame slowly. The seat push frame swings up and down with the limiting spindle 22 as the center. The trainee can hold the seat push rod 07 at different positions with both hands according to his own needs.

[0027] As a specific implementation method, Figure 2 As shown, the adjustable counterweight unit 01 includes a U-shaped counterweight rod 11 fixedly arranged on the side of the sit push frame and perpendicular to it, a sliding rod 12 is fixedly arranged 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 axially limited by a limit assembly and the sliding rod 12.

[0028] 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.

[0029] As a specific implementation method, Figure 3-5 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 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 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 .

[0030] 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.

[0031] 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.

[0032] As a specific implementation method, Figure 1 As shown, the push-up stand comprises an upper arm 09, a forearm 08 and a connecting arm 10, wherein the upper arm 09 and the forearm 08 are fixedly connected at their head ends, the forearm 08 is fixedly connected at its tail end to the connecting arm 10, and the tail end of the upper arm 09 and the tail end of the connecting arm 10 are rotatably connected to the hinge seat at the top of the main frame 02 via a limiting spindle 22. The connecting arm 10 enables the upper arm 09 and the forearm 08 to form a stable structure. The push-up rod 07 is an inwardly bent L-shaped structure, and different strength and muscle group training can be achieved by holding it at different positions.

[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 arranged parallel to the crossbeam 03. The two ends of the reference rod 21 are fixedly connected to the two columns, and a 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 fixedly connected to the upper arm 09 of the push-up frame through the pin 00. The limit shaft 123 is vertically fixedly connected to the upper arm 09 of the push-up frame. The tops of the two columns are tilted at a certain angle. The bottom of the column and the bottom of the L-shaped support rod 04 are buried below the ground, and the reference rod 21 is the horizon.

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

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the scope of protection of the claims of the utility model.
