Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, and in particular relates to a stretching training device. Background Technology

[0002] Chinese utility model patent CN220736094U discloses a simple indoor strength training device, comprising a training device suspended in a doorway-shaped support surface. A horizontal bar is provided within the doorway-shaped cavity of the support surface for a gripping part A. A pair of parallel curved connecting arms are symmetrically arranged on the same side, perpendicular to the extension direction of the horizontal bar. Each curved connecting arm includes a fixed end and an adjustable end. A hook is connected to the adjustable end of the connecting arm, and the hook suspends the device on the upper surface of the support surface. The bending direction of the curved connecting arms is consistent with the suspension direction of the hooks. The two ends of the horizontal bar extend symmetrically outwards, with extension ends horizontally abutting against the two sides of the support surface. The horizontal bar and hooks create a clamping force on the support surface, forming a simple arm strength stretching training device. This utility model allows for height adjustment via adjusting bolts to adapt to different practical application scenarios. All components can be quickly disassembled by hand, facilitating transport and installation.

[0003] When implementing the above scheme, since the pair of parallel curved connecting arms are not directly connected to each other, the pair of parallel curved connecting arms often shift during use. Summary of the Invention

[0004] The purpose of this utility model embodiment is to provide a stretching trainer that aims to solve the technical problem that the pair of parallel curved connecting arms often shift during use because they are not directly connected to each other.

[0005] The present invention is implemented as follows:

[0006] A stretching trainer is detachably fixed to a door frame. The stretching trainer includes a first fixing beam for fixing to the door frame. L-shaped support rods are connected to both ends of the first fixing beam. The support rods include a vertical section and a second horizontal section. A second fixing beam is fixed to the middle of the second horizontal section. A counter is provided in the middle of the second fixing beam. A handle is provided at the end of the second horizontal section away from the first fixing beam.

[0007] Furthermore, each end of the first fixed beam is connected to a symmetrically arranged L-shaped support rod.

[0008] Furthermore, the two ends of the first fixed beam are fixed to the ends of the vertical section of the L-shaped support rod by welding or bolting.

[0009] Furthermore, the end of the second horizontal segment bends laterally to form a curved segment, and the curved segment extends backward to form the first horizontal segment; the second horizontal segment, the first horizontal segment, and the curved segment form a shape that makes up the letter V.

[0010] Furthermore, the handle is divided into a first handle located in the second horizontal section, a second handle located in the curved section, a third handle located at the end of the handle shaft, and a fourth handle located in the first horizontal section.

[0011] Furthermore, several anti-slip sleeves are provided at the contact points between the second crossbeam and the wall.

[0012] Furthermore, the counter includes a counter body and a frame-shaped shield located at the counter detection end, the frame-shaped shield being used to block the infrared detection light of the counter.

[0013] The positive effects of this utility model are as follows: the ends of the two L-shaped support rods are connected by the first fixed beam, and the middle of the second horizontal section of the L-shaped support rods is connected by the second fixed beam to form a spatial frame structure, which enhances the stability. At the same time, a counter is provided in the middle of the second fixed beam. Each time the user stretches his head beyond the height of the connecting tube, the counter can be counted by infrared sensing, which can record the number of stretching exercises in real time and provide a record for the user during training.

[0022] like Figures 1 to 4 The diagram shown is a structural diagram of a stretching trainer provided in an embodiment of the present invention. The stretching trainer is used to be detachably fixed to a door frame. The stretching trainer includes a first fixing beam 1 for fixing to the door frame. L-shaped support rods are connected to both ends of the first fixing beam 1. The support rods include a vertical section 2 and a second horizontal section 13. A second fixing beam 4 is fixed in the middle of the second horizontal section. A counter 8 is provided in the middle of the second fixing beam 4. A handle is provided at the end of the second horizontal section 13 away from the first fixing beam 1.

[0023] In this embodiment of the utility model, the ends of two L-shaped support rods are connected by a first fixed beam 1, and the middle part of the second horizontal section 13 of the L-shaped support rods is connected by a second fixed beam 4 to form a spatial frame structure, which enhances the stability. At the same time, a counter is provided in the middle of the second fixed beam 4. Each time the user stretches his head beyond the height of the connecting tube, the counter can be counted by infrared sensing, which can record the number of stretching exercises in real time and provide a record for the user during training.

[0024] Specifically, such as Figures 1 to 4 As shown, a stretching trainer is used to be detachably fixed to a door frame. The stretching trainer includes a first fixing beam 1 for fixing to the door frame. The first fixing beam 1 has L-shaped support rods connected to both ends. The support rods include a vertical section 2 and a second horizontal section 13. A second fixing beam 4 is fixed in the middle of the second horizontal section. A counter 8 is provided in the middle of the second fixing beam 4. A handle is provided at the end of the second horizontal section 13 away from the first fixing beam 1.

[0025] Preferably, the first fixed beam 1 is connected to symmetrically arranged L-shaped support rods at both ends.

[0026] Preferably, the two ends of the first fixed beam 1 are fixed to the ends of the vertical section 2 of the L-shaped support rod by welding or bolting.

[0027] Preferably, the end of the second horizontal segment 13 bends laterally to form a curved segment 7, and the curved segment 7 extends backward to form the first horizontal segment 5; the second horizontal segment 13, the first horizontal segment 5 and the curved segment 7 form the shape of the letter V.

[0028] Preferably, the middle part of the second horizontal segment 13 and the end of the first horizontal segment 5 are both fixedly connected to the second fixed beam 4.

[0029] Preferably, the end of the second horizontal segment 13 near the curved segment 7 and the end of the first horizontal segment 5 near the curved segment 7 are fixedly connected together by the handle shaft 6.

[0030] The handle is divided into a first handle 9 located in the second horizontal section 13, a second handle 10 located in the curved section 7, a third handle 11 located at the end of the handle shaft 6, and a fourth handle 12 located in the first horizontal section 5. The multiple handles at different angles can meet the stretching training of different arm muscles at different angles.

[0031] Preferably, a number of anti-slip sleeves 3 are provided at the contact position between the second crossbeam 4 and the wall 15.

[0032] Preferably, all handles are equipped with a hand-held heart rate monitoring device, which allows users to monitor their physical condition in real time.

[0033] Preferably, the counter 8 includes a counter body 802 and a frame-shaped shield 801 located at the counter detection end. The frame-shaped shield 801 is used to block the infrared detection light of the counter to ensure that the user can only be detected when he / she reaches a sufficiently high position, so as to achieve standardized constraints on the training movements of the trainee.

[0034] In practical use, such as Figure 2 As shown, the first fixing beam 1 is clipped onto the top of the door frame 14. At this time, the side of the first fixing beam 1 is in contact with the wall 15, while the anti-slip sleeve 3 of the second fixing beam 4 is in contact with the other side of the wall 15. When the user practices at the handle, as... Figure 2 The third handle 11 or the seventh handle 7 in the middle, at this time the user's weight will apply a clockwise torque to the entire device, so that the first crossbeam 1 and the second crossbeam 4 have a tendency to rotate momentarily, and then the force brought by the clockwise torque is applied to the surface of the wall 15, and the entire device is fixed at the door frame by friction.
