Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, and in particular to a traction device for gymnastics equipment. Background Technology

[0002] Existing gymnastics equipment, such as the horizontal bar, rings, and uneven bars, is typically secured by connecting cables or other connectors to pre-embedded parts or stakes in the ground. Many related patented technologies also exist.

[0003] For example, Chinese Patent Application No. 201721918317.9 discloses a horizontal bar for physical exercise, including a horizontal bar extending to the left and right, and a vertical column fixed at both ends of the horizontal bar and extending vertically. It also includes a flat rectangular base and steel cables arranged on the front and rear sides of the vertical column. The lower end of the vertical column is welded and fixed to the upper end of the base. The lower end of the base has a fixing plate extending horizontally outward. Multiple anchor bolts are evenly distributed along the circumference of the base through the fixing plate. The anchor bolts are used to fix the base to the ground. The upper end of the steel cable is connected to the vertical column, and the lower end of the steel cable is used to anchor to the ground. Reinforcing ribs are also welded and fixed at the connection between the vertical column and the base.

[0004] Typically, including other existing technologies, the middle section of the steel cable has a mechanical device for adjusting the cable tension, allowing athletes to tighten or loosen the cable according to their weight. However, there is no data to reference for this tension; it all relies on the feel and experience of the athlete or coach. This results in relatively low precision and controllability in the adjustment. Utility Model Content

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.

[0021] Examples, such as Figure 1 , 2 As shown, a tension device for gymnastics equipment includes a tension sensor 1. The tension sensor 1 has an upper fisheye screw 11 and a lower fisheye screw 12. This structure is a relatively existing conventional tension sensor structure. The main panel on the front of the tension sensor 1 can display the tension value. Through the tension on both sides of the upper fisheye screw 11 and the lower fisheye screw 12, the tension measuring part in the middle is activated, and the measured value can be displayed on the panel. The tension measuring part in the middle is set inside the tension sensor 1. Furthermore, a first tension section 21 is connected to the fisheye of the upper fisheye screw 11, and the other end of the first tension section 21 is connected to the main body of the gymnastics equipment as a fixed object. A second tension section 22 is connected to the fisheye of the lower fisheye screw 12, and the other end of the second tension section 22 is fixedly connected to the ground or other fixed objects as a free end.

[0022] With this design, during the installation and connection pulling process, the magnitude of the pulling force can be seen from the tension sensor 1, and the required value can be adjusted as needed. Then, the free ends of the first pulling section 21 and the second pulling section 22 can be fixedly connected to the corresponding fixed objects.

[0023] Preferably, the entire traction device also includes a lower tension guide device through which the second traction section 22 passes. The lower end of the second traction section 22 is connected to a telescopic tension drive mechanism 3. During installation and use, the tension of the traction section is adjusted. The tension drive mechanism 3 controls the tension of the second traction section 22 by extending and retracting. Simultaneously, the tension of the first traction section 21 is also adjusted, as it is stretched together with the second traction section 22, including the tension sensor 1 itself. The action primarily occurs on the lower side of the second traction section 22. The lower tension guide device provides guidance during adjustment, ensuring proper movement of the second traction section 22 and improving stability and reliability.

[0024] Furthermore, the downward stretching guide device includes a shaft frame 4 for fixing to a fixed object. The shaft frame can be an existing structural component and fixed to the ground. An upper guide wheel 41 and a lower guide wheel 42 are installed on the shaft frame 4, which are spaced apart vertically. A gap is formed between the upper guide wheel 41 and the lower guide wheel 42 for the second stretching section 22 to pass through. The second stretching section 22 can be well abutted and guided between the upper guide wheel 41 and the lower guide wheel 42. The upper guide wheel 41 and the lower guide wheel 42 can be V-shaped guide wheels.

[0025] Furthermore, the tension drive mechanism 3 is a gas spring rod. The piston rod of the gas spring rod is fixedly connected to the lower end of the second tension section 22, and the outer shell of the gas spring rod is used to fix it to the fixed object. With this configuration, the extension and retraction of the gas spring rod can be easily adjusted to control the tension. The gas spring rod can be operated manually or automatically controlled by an existing controller via electrical connection. Of course, the tension drive mechanism 3 can also be an electric rod or other tensioning equipment.

[0026] Preferably, the first tension section 21 and the second tension section 22 are structures connected by at least one of the following: wire rope, steel cable, chain, turnbuckle, or lock. That is, regardless of whether it is the first tension section 21 or the second tension section 22, they can be formed by connecting one or more of these structural components in series. The turnbuckle is not only a connector but also a manually adjustable component; the overall tightness can be adjusted by rotating the adjusting screw. However, this requires manual adjustment, making the operation slightly cumbersome, and is suitable for fine-tuning or for placement in a higher position suitable for standing operation. The wire rope, steel cable, and chain can use existing steel structures, and the lock can be a safety buckle, carabiner, or other easy-to-assemble / disassemble type.

[0027] Furthermore, it also includes an inclined positioning device for tilting and guiding the tension sensor 1. The tension sensor 1 lies on the inclined positioning device with its front facing up, so that the tension sensor 1 has a place to lean against, and the tilt angle is controllable, so as to keep the tilt angle consistent each time the tension sensor 1 is installed to measure force.

[0028] Preferably, the tilt positioning device includes a support column 5 for fixing to a fixed object and a main tilt support plate 51 with an inclined shape installed on the support column 5 for the back of the tension sensor 1 to abut against. In this way, the tension sensor 1 has a good support position, will not be suspended, and is safer and more stable.

[0029] Furthermore, a left side plate 511 and a right side plate 512, spaced apart from each other, are fixed to the upper surface of the main inclined support plate 51. The left side plate 511 and the right side plate 512 are used to block and abut against the left and right sides of the tension sensor 1, respectively, thus providing lateral support. The tension sensor 1 is positioned between the left side plate 511 and the right side plate 512. Elastic guide wheels can also be installed on the left side plate 511 and the right side plate 512 to provide better guidance and support for the side of the tension sensor 1. Furthermore, a left upper baffle 5111 is integrally connected to the upper side of the left side plate 511, and a right upper baffle 5121 is integrally connected to the upper side of the right side plate 512. The left upper baffle 5111 and the right upper baffle 5121 are used to block the upper sides of the left and right sides of the tension sensor 1, respectively. The left upper baffle 5111 and the right upper baffle 5121 are spaced apart to expose the main body panel of the tension sensor 1. This design also provides some guiding and limiting effect on the upper part. The gap between the upper left baffle 5111 and the upper right baffle 5121 is for the convenience of display and operation buttons, etc. Of course, the upper left baffle 5111 and the upper right baffle 5121 can also be equipped with elastic guide wheels.

[0030] Furthermore, the tilt angle of the main tilting support plate 51 can be adjusted and fixed. This means that the tilt angle of the main tilting support plate 51 needs to be precisely controlled and stabilized. The support column 5 and the main tilting support plate 51 can be initially rotatably connected, such as by a hinge. Then, a tie rod can be installed between them. The tie rod can be a telescopic screw structure or a pneumatic rod structure. An angle sensor such as a gyroscope can be installed on the main tilting support plate 51 to accurately determine the tilt angle. This is one implementation method. Alternatively, the support column 5 and the main tilting support plate 51 can be directly connected using an existing rotatable and adjustable gear connection structure. Of course, other rotatable and adjustable structures are also possible.

[0031] Through the aforementioned designs, the pulling force and angle of the traction device can be controlled more precisely, making each installation controllable and more suitable for the stability of athletes' training and competition.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
