Description

TECHNICAL FIELD

[0001] The utility model relates to the field of body -building equipment. BACKGROUND

[0002] Traditional double-arm opening and closing type body-building equipment mostly adopts the mode that spring directly connects resistance arm, and has problems such as unadjustable resistance, stiff movement track, lack of movement data feedback, etc. The Chinese patent document with the announcement number CN216824694U discloses a leg clamping device, comprising two main body parts, characterized in that: it further comprises a metal spring body, the metal spring body comprises a bending part and connecting parts arranged at both ends of the bending part, the main body parts are fixedly connected with the connecting parts, the bending part is bent on a plane circumference, and the connecting parts at both ends of the bending part face each other.

[0003] The above-mentioned body-building equipment is a structure that directly connects two main body parts by a metal spring body, which not only cannot adjust the resistance in the process of use, but also needs to be placed between the two legs for opening and closing movement when used, so that the metal spring body provides resistance, which often cannot provide stable resistance, thereby resulting in poor exercise effect. UTILITY MODEL CONTENT

[0004] The utility model aims at providing a kind of exercise device with more reasonable structure and better exercise effect.

[0005] To achieve the above-mentioned purpose, the technical scheme adopted by the utility model is as follows:

[0006] An exercise device, comprising a base, two resistance arms and a resistance mechanism, the two resistance arms are respectively rotationally connected with the base, the two resistance arms are relatively openable and closable, the resistance mechanism provides resistance for the relative closing of the two resistance arms, characterized in that: the resistance mechanism comprises a sliding block and a resistance piece, the sliding block is movably arranged on the base, the resistance piece is used to provide resistance to the upward movement of the sliding block, the resistance arm comprises a first driving part, the sliding block is provided with a second driving part abutting against the first driving part, and the first driving part and the second driving part are arranged to cooperate to drive the sliding block to move upward against the resistance of the resistance piece when the two resistance arms are relatively closed and rotated.

[0007] By adopting the above-mentioned technical scheme, when the two resistance arms are relatively closed and rotated, the first driving part of the resistance arm abuts against the second driving part of the sliding block, so that the rotation of the resistance arm also drives the sliding block to move when the resistance arm rotates, thereby making the sliding block move upward against the resistance. The resistance is transmitted by the vertical movement of the sliding block, so that the resistance direction is consistent with the human force direction, which is more consistent with the force when the human body exercises, to bring better exercise effect.

[0008] The second driving part comprises a first arc-shaped abutting surface protruding outward, and the first arc-shaped abutting surface can abut against the top surface of the first driving part.

[0009] By adopting the technical scheme, the contact surface between the arc surfaces is small, so that the arc surface guiding resistance arm opening and closing action is more smooth, and the jamming phenomenon of right-angle contact is avoided.

[0010] The second driving part further comprises a second arc-shaped abutting surface concave, and the front end of the first driving part is arc-shaped and matched with the second arc-shaped abutting surface.

[0011] By adopting the technical scheme, the second arc-shaped abutting surface concave can play a certain limiting role, preventing the two resistance arms from being excessively closed or excessively opened due to excessive rotation.

[0012] The sliding block is formed with an avoiding groove avoiding the first driving part.

[0013] By adopting the technical scheme, when the two resistance arms are relatively opened and closed, the avoiding groove provides space for the first driving part, preventing structural collision.

[0014] The resistance arm comprises a rod-shaped main body and the first driving part extending inward from the upper end of the rod-shaped main body, and the included angle between the rod-shaped main body and the first driving part is 70-120 degrees.

[0015] By adopting the technical scheme, the angle range of 70-120 degrees is matched with the natural force angle during human body exercise.

[0016] The resistance arm is rotationally connected with the base through a rotating shaft, and the rotating shaft is arranged at one end of the first driving part close to the rod-shaped main body.

[0017] By adopting the technical scheme, the rotating shaft is arranged close to the connecting position of the rod-shaped main body, reducing the torque load of the rotating shaft during movement, and also facilitating assembly.

[0018] The first driving part is a rod-shaped structure.

[0019] By adopting the technical scheme, the rod-shaped structure has better bending resistance, avoiding deformation caused by frequent use.

[0020] The resistance part comprises a pull rod, a compression spring and an adjusting nut, the upper end of the pull rod is connected with the sliding block, the lower section of the pull rod is formed with external threads, the adjusting nut is threadedly matched with the external threads, and the compression spring is sleeved on the pull rod and compressed between the base and the adjusting nut.

[0021] By adopting the technical scheme, the spring compression amount is changed by rotating the adjusting nut, continuous resistance adjustment is realized, so as to adjust the resistance to the required resistance.

[0022] Further comprising a spacer sleeve, the spacer sleeve is sleeved on the pull rod and located between the compression spring and the adjusting nut.

[0023] By adopting the above technical solution, the spacer prevents the compression spring from shifting during use, thus preventing the compression spring from detaching from the pull rod.

[0024] It also includes a counter, which includes a controller, a magnetic sensor, and a magnet. The controller is mounted on the base, and the magnetic sensor is connected to the controller. The first drive unit is equipped with a magnet that can be sensed by the magnetic sensor. When the resistance arm rotates, the magnetic sensor can detect the position change of the magnet and feed it back to the controller, which then generates and displays the number of workouts.

[0025] By adopting the above technical solution, the magnetic sensor detects changes in the position of the magnet, which can accurately record the user's exercise status, so as to facilitate the user to formulate a training plan.

[0026] It also includes two leg rests, which are respectively located on the outer side of the lower end of the two resistance arms.

[0027] By adopting the above technical solution, the leg rest component can facilitate users to perform opening and closing leg-clamping exercises. Attached Figure Description
