[0024] 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.

[0025] The utility model discloses a strength type bench press training device, such as Figure 1 As shown, it includes a main frame 02, the bottom of which is fixed to the ground, and bench press frames are provided on both sides of the top. An adjustable counterweight unit 01 is provided on the side of the bench press frame, and the adjustable counterweight unit 01 is located on the outside of the bench press frame and in the middle of the top of the bench press frame. A bench press rod 07 is fixed at the head end of the bench press frame, and the tail end of the bench press frame is hinged to the top of the main frame 02. An L-shaped support rod 04 is fixed at the bottom of the bench press frame, and the L-shaped support rod 04 is fixedly connected to the main frame 02 through a crossbeam 03. A bench press plate 05 is provided on the top of the L-shaped support rod 04; the bench press plate 05 is arranged below one side of the head end of the bench press frame, and the L-shaped support rod 04 is inverted and arranged on one side of the head end of the bench press frame, 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 crossbeam 03. When in use, the trainee sits on the bench press board 05, holds the bench press rod 07 with both hands, and repeatedly pushes up and down the bench press frame slowly, so that the bench press frame swings up and down with the limiting spindle 22 as the center.

[0026] As a specific implementation method, Figure 2 As shown, the adjustable counterweight unit 01 includes a U-shaped counterweight rod 11 fixedly mounted on the side of the bench press frame and arranged perpendicularly thereto, a sliding rod 12 is fixedly mounted on the rod body at both ends of the U-shaped counterweight rod 11, a plurality of counterweight plates 13 are slidably mounted on the sliding rod 12, and are axially limited by a limit assembly and the sliding rod 12.

[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, 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 .

[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] In the conventional technology, the indoor counterweight sheet 13 is often placed on a storage rack or on the ground. When adjusting the counterweight, it needs to be moved around. When not in use, the scattered counterweight sheets 13 need to be sorted on the storage rack. The counterweight sheet 13 in the utility model is limited to the U-shaped counterweight rod, and there is no need to carry and sort the counterweight sheet 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 implementation method, Figure 1 As shown, the bench press frame includes an upper arm 09, a forearm 08 and a connecting arm 10, wherein the upper arm 09 and the head end of the forearm 08 are fixedly connected, the tail end of the forearm 08 is fixedly connected to the head end of 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 through a limiting main shaft 22. The connecting arm 10 forms a stable structure with the upper arm 09 and the forearm 08. The bench press rod 07 is an L-shaped structure that bends inwards. During training, the inner bending position is held, and the position where the hand is held on the bench press rod is covered with a protective cover to improve comfort and prevent the palm from being worn and injured.

[0032] 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 below the crossbeam 03 in parallel. 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 the two 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 bench press frame through a pin 00. The limit shaft 123 is vertically fixedly connected to the upper arm 09 of the bench press 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.

[0033] To sum up, the utility model solves the problem that the outdoor bench press training device in the traditional technology often adopts fixed weights, and its weight cannot be adjusted, and cannot meet the usage needs of different groups. The utility model realizes adjustable weights and convenient adjustment, and can also avoid loss, playing the role of anti-theft of weight plates, and is suitable for the field of sports equipment technology.

[0034] 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.
