[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1 to 4 The present invention provides a technical solution: a lying weight training device, comprising two U-shaped frames 16 with openings facing downwards and arranged in parallel, the bottom of each U-shaped frame 16 being mounted on a strip support 4, one side of the two U-shaped frames 16 being connected by a support beam 3, a human body support portion being provided in the middle of the support beam 3, during actual use, a human body can lie flat on the human body support portion, in order to make the space between the two U-shaped frames 16 more stable, such as Figure 2 As shown, the U-shaped frames 16 are further connected by at least one reinforcing rod 22 .

[0030] A weight-lifting bar 15 is horizontally provided above the human body support part, and the human body can hold the weight-lifting bar 15. In the initial state, there is a certain distance between the weight-lifting bar and the human body to prevent contact with the human body. The two ends of the weight-lifting bar 15 are respectively connected to the sliders 29, and each slider 29 is slidably set on the guide rail 13, and the guide rail 13 is located on the side of the U-shaped frame 16. The guide rail 13 is installed on the side of the U-shaped frame 16, so when the weight-lifting bar 15 is lifted, the weight-lifting bar 15 can make a linear motion up and down along the guide rail 13, which can prevent the weight-lifting bar 15 from tilting.

[0031] like Figure 1 As shown, the two sliders 29 are provided with a connecting seat 14 on the side away from each other, and each connecting seat 14 is connected to a pull rope 9, which is preferably a steel wire rope. In fact, the connecting seat 14 is located outside the U-shaped frame 16, and there is no contact between the two.

[0032] A first guide mechanism is installed below each side of the U-shaped frame 16. The first guide mechanism is located below and includes two first guide groove wheels 5 installed below the side of the U-shaped frame 16. The first guide groove wheels 5 are rotatably mounted on the U-shaped frame 16, and the two first guide groove wheels 5 are clearance-fitted.

[0033] A second guide mechanism is provided at the top of each U-shaped frame 16. The second guide mechanism includes a mounting frame 12 mounted in the top of the U-shaped frame 16. Two second guide groove wheels 10 are rotatably mounted on the mounting frame 12. The two second guide groove wheels 10 are clearance-fitted.

[0034] Under each U-shaped frame 16, there is a weight, which includes a weight block 6, such as Figure 1 As shown, the pull rope 9 is connected to the top of the weight block 6, and the pull rope 9 is connected to the load through the first guide mechanism and the second guide mechanism respectively, that is, the pull rope 9 is placed in the first guide groove wheel 5 and the second guide groove wheel 10. Each group of guide wheels has two and are provided with clearance fit, which can prevent the pull rope from falling off from the inside of the wheel;

[0035] The present application also adds a guide mechanism to the weights, which is used to offset the position of the weight block. That is, two guide shafts 7 are provided through the weight block 6. The bottom of the guide shaft 7 is connected to the strip support 4, and the top of the guide shaft 7 is connected to the fixed seat 8. The fixed seat 8 is mounted on the connecting frame 11, and the connecting frame 11 is mounted in the U-shaped frame 16. Therefore, the pull rope 9 drives the weight-lifting rod 15 to descend along the guide rail 13 by relying on the weight of the weight block 6 itself. The weight-lifting rod is then positioned above the human body. At this time, the human body can lift the weight-lifting rod by holding the weight-lifting rod with both hands. In the process of the weight-lifting rod moving up and down, the weight-lifting rod will not be offset, and will not fall on the human body due to lack of control.

[0036] The specific structure of the human body support portion will be described below. It includes a bar frame 1 placed above the middle of the support beam 3. Both sides of the bar frame 1 are connected to the support beam 3 through a first support pad 2. A support leg 17 is installed at one end of the bar frame 1 away from the first support pad 2. A bar plate 19 is provided on the top of the bar frame 1. The bar frame 1 is rotatably connected to the end of the bar plate 19 close to the support leg 17, so that the bar plate 19 can rotate around one end of the bar frame 1, so that the height of the bar plate 19 can be adjusted. A protective pad 18 is provided on the surface of the bar plate 19, and the human body lies directly on the protective pad 18.

[0037] like Figure 4 As shown, a lead screw 24 is provided at the middle position below the bar frame 1. Both ends of the lead screw 24 are rotatably mounted in bearing seats 23. Two bearing seats 23 are respectively mounted below the two ends of the bar frame 1. A movable seat 25 is threadedly connected to the lead screw 24.

[0038] The top of the movable seat 25 is provided with a strip seat 28 vertically arranged with the lead screw, and the top of the strip seat 28 is rotatably connected with at least one support rod 26, and the support rods 26 are preferably two and symmetrically arranged, such as Figure 4 As shown, the support rod 26 is arranged at an angle and the other end thereof is rotatably connected to the bottom surface of the strip plate 19. One end of the screw 24 is connected to the crank 20. When the crank 20 is turned, the screw can be driven to rotate, and the screw drives the strip seat 28 to reciprocate. Therefore, when the strip seat 28 drives the support rod 26 to move, the top of the support rod 26 will rotate around the bottom of the strip plate 19, causing the support rod 26 to gradually rise or fall, thereby allowing the strip plate 19 to be raised and lowered.

[0039] A guide rod 27 is also installed on the bar seat 28, that is, at least one guide rod 27 is slidably provided on the bar seat 28, and the guide rod 27 is parallel to the lead screw 24. The two ends of the guide rod 27 are respectively connected to the two ends of the bar frame 1. The guide rod 27 can guide the bar seat 28 to make the movement of the bar seat 28 more stable.

[0040] When the strip board 19 is lowered, the strip board 19 is horizontal, and two second support pads 21 are symmetrically provided at the bottom of one end of the strip board 19 away from the support leg 17. The bottom of the second support pad 21 is placed on the strip frame 1, and the second support pad 21 supports the strip board 19.
