A bidirectional tensioner

Abstract

This utility model relates to the field of fitness equipment technology and discloses a bidirectional tensioner, including a connecting seat. The upper end of the connecting seat is provided with two sets of symmetrical first adjusting rods. An adjusting component is provided at the end of each first adjusting rod away from the connecting seat. The adjusting component includes a second adjusting rod located below the front end of each first adjusting rod. When it is necessary to adjust the resistance of the spring according to usage requirements, an adjusting bolt can be unscrewed from the adjusting hole, and an adjusting disc can be slid along the outer wall of the fixed rod. The adjusting disc drives the sliding sleeve to slide along the fixed rod and compress the spring. When the spring length decreases, the resistance provided by the spring is greater, which is suitable for users who require greater arm strength training. Then, the adjusting bolt is screwed into the corresponding adjusting hole to complete the fixing of the adjusting disc.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Example 1

[0022] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a bidirectional tensioner, including a connecting seat 1. The upper end of the connecting seat 1 is provided with two sets of first adjusting rods 2 that are symmetrical to each other. The end of the first adjusting rod 2 away from the connecting seat 1 is provided with an adjusting component 3. The adjusting component 3 includes a second adjusting rod 31 located on the lower side of the front end of the first adjusting rod 2. The outer wall of the connecting seat 1 is provided with a fixing rod 34. The outer wall of the fixing rod 34 is respectively fitted with a sliding sleeve 35 and an adjusting plate 36. The upper end of the adjusting plate 36 is threaded with an adjusting bolt 37. The upper end of the fixing rod 34 is evenly provided with multiple sets of adjusting holes 38. The outer wall of the fixing rod 34 located between the connecting seat 1 and the sliding sleeve 35 is fitted with a spring 4.

[0023] The end of the first adjusting rod 2 away from the second adjusting rod 31 is rotatably connected to the upper end of the connecting seat 1.

[0024] A rotating rod 32 is inserted at the end of the first adjusting rod 2 away from the connecting seat 1. The rotating rod 32 moves from top to bottom through the first adjusting rod 2 and the second adjusting rod 31 in sequence. A connecting sleeve 33 is threaded onto the lower end of the rotating rod 32.

[0025] The end of the second adjusting rod 31 away from the rotating rod 32 is hinged to the outer wall of the sliding sleeve 35, and the sliding sleeve 35 is movably sleeved on the outer wall of the fixed rod 34.

[0026] The adjusting disc 36 is movably sleeved on the outer wall of the fixed rod 34, and the lower end of the adjusting bolt 37 is movably inserted into one of the adjusting holes 38.

[0027] The outer wall of the first adjusting rod 2 is fixedly fitted with a rubber sleeve 6, and the end of the connecting seat 1 away from the fixed rod 34 is fixedly fitted with a hook 7. The hook 7 allows the device to be suspended when not in use, making it convenient for storage. The rubber sleeve 6 can increase the comfort of holding the first adjusting rod 2.

[0028] Protective plates 5 are fixedly installed on both sides of the fixed rod 34 on the outer wall of the connecting seat 1. If the hand loses strength during training, the protective plates 5 can prevent the hand from directly contacting the spring 4 and the fixed rod 34, thereby avoiding the probability of injury during training and increasing the safety of the device.

[0029] Users who need to exercise their arms should hold the rubber sleeves 6 on the outer wall of the first adjusting rod 2 with both hands and pull the first adjusting rod 2 to both sides. The first adjusting rod 2 rotates at a certain angle. At the same time, the end of the first adjusting rod 2 away from the connecting seat 1 rotates along the rotating rod 32, and the second adjusting rod 31 rotates along the rotating rod 32. The two sets of second adjusting rods 31 open at a certain angle to each other. The second adjusting rod 31 drives the sliding sleeve 35 to slide along the outer wall of the fixed rod 34 and compress the spring 4. Under the resistance of the spring 4, the arm muscles are exercised. When it is necessary to adjust the resistance of the spring 4 according to the user's needs, the adjusting bolt 37 can be unscrewed from the adjusting hole 38 and the adjusting plate 36 can be slid along the outer wall of the fixed rod 34. The adjusting plate 36 drives the sliding sleeve 35 to slide along the fixed rod 34 and compress the spring 4. When the length of the spring 4 is smaller, the resistance provided by the spring 4 is greater, which is suitable for users who have greater needs for arm strength training. Then, the adjusting bolt 37 is screwed into the corresponding adjusting hole 38 to fix the adjusting plate 36.
