Description

Technical Field

[0001] The technical solution belongs to the technical field of fitness equipment, and specifically is a dumbbell bench that is easy to adjust. Background Art

[0002] Dumbbell benches are common fitness equipment, widely used in home gyms, professional fitness studios, and rehabilitation training settings. Their primary function is to provide stable support for various strength training exercises and core training. The design of the dumbbell bench, particularly the adjustable backrest, is crucial for various exercises, such as the flat bench press, incline bench press, and seated shoulder press. To accommodate the posture and angle requirements of various exercises, the backrest must be adjustable in length and angle.

[0003] However, traditional dumbbell benches have certain limitations when it comes to adjusting the back pad. First, users need to operate two independent adjustment mechanisms: one for adjusting the angle of the back pad and the other for adjusting the length of the back pad. This not only increases the complexity of use, but also requires users to spend extra time and energy adjusting the equipment during training, affecting training efficiency and user experience. In addition, during the angle and length adjustment process, due to the cumbersome adjustment mechanism, users may not be able to accurately control the inclination angle and length of the back pad, affecting the exercise effect and even increasing the risk of injury.

[0004] Therefore, to improve the practicality and user-friendliness of dumbbell benches, a new design is urgently needed that can simplify the adjustment of the dumbbell bench back pad, allowing users to more easily and quickly adjust the length and angle of the back pad. The introduction of an integrated adjustment device will greatly improve this situation. Users can adjust the length and angle of the back pad simultaneously through a single operating mechanism, which not only improves adjustment efficiency but also enhances stability and safety during use. This innovative design will enable the dumbbell bench to meet different training needs while further optimizing the user experience, bringing more efficient and convenient use to fitness enthusiasts. Summary of the Invention

[0005] In order to solve the above technical problems, the present utility model discloses the following technical solutions:

[0006] A dumbbell bench that is easy to adjust, comprising a seat plate, a support tube hinged to one side of the seat plate, the support tube comprising a first adjustment tube and a second adjustment tube, one end of the first adjustment tube being hinged to one side of the seat plate, the other end of the first adjustment tube being provided with a second adjustment tube, the second adjustment tube being slidable inside the first adjustment tube to adjust the length of the support tube, and a fastening device being provided on the support tube for fixing the second adjustment tube to the first adjustment tube after the length of the support tube is adjusted;

[0007] The seat plate is provided with a base at the bottom, and a telescopic rod is hinged between the base and the second adjusting tube. When the fastening device is opened, the telescopic rod can be extended and retracted to drive the second adjusting tube to slide in the first adjusting tube to adjust the length of the support tube, and after the fastening device fixes the second adjusting tube on the first adjusting tube, the telescopic rod can be used to adjust the angle between the support tube and the seat plate, so that the force required to adjust the angle between the seat plate at one end of the first adjusting tube can be increased, so that when the fastening device is opened, the length of the back cushion can be first changed by changing the length of the telescopic rod without changing the angle between the first adjusting tube and the seat plate.

[0008] Furthermore, the first adjustment tube and the second adjustment tube are provided with adjustment holes that cooperate with each other, and the fastening device is a latch;

[0009] Preferably, the latch is a spring-loaded pull pin, a spring-loaded mechanical locking device that can be quickly locked or released with a simple pull or push.

[0014] Furthermore, the force required to adjust the angle between one end of the first adjusting tube and the seat plate can be increased by increasing the friction at the hinge between the first adjusting tube and the seat plate.

[0015] Furthermore, a friction layer is provided at the hinge between the first adjustment tube and the seat plate.

[0016] Preferably, the friction layer is a high-friction coating, or may be a friction plate or friction belt: adding friction material or friction plate can increase the resistance of the connecting part during rotation. The friction mechanism can change the force required for angle adjustment by adjusting the pressure or contact area.

[0017] As another option, a magnetic resistance device can also be selected: a magnetic resistance mechanism is set at the hinge position, and the force when adjusting the angle is increased or decreased by adjusting the magnetic field strength or the relative position between the magnets.

[0018] Furthermore, the angles between the connecting rod and the front connecting rod and the seat plate are obtuse angles to increase the stability of the device.

[0019] Furthermore, the extension lines of the support rod and the connecting rod and the telescopic rod form a triangle, and the angle between the connecting rod and the telescopic rod is an obtuse angle, so as to better adjust the length of the back pad.

[0020] Furthermore, a chassis is provided at the bottom of the cross bar and the fixed beam. When in use, the seat is parallel to the ground. The cross sections of the seat, the ground, the connecting rod and the front connecting rod are trapezoidal to further increase the structural stability of the device.

[0021] Furthermore, the telescopic rod is a locking telescopic rod, so that after the user adjusts it to the desired length, the telescopic rod can be fixed through a built-in locking mechanism so that its length will not change due to external force before it is unlocked. The telescopic rod is a self-locking gas spring, so that the length of the telescopic rod can be adjusted through the gas spring. The telescopic rod can also be an electric telescopic rod with a locking function.

[0022] Compared with the prior art, the present invention has the following outstanding beneficial effects:

[0023] This utility model utilizes a control fastening device in conjunction with a telescopic rod to adjust the back cushion's length and angle. This simplifies the dumbbell bench's back cushion adjustment method, allowing users to adjust the length and angle more easily and quickly. The introduction of an integrated adjustment mechanism will significantly improve this situation. Users can simultaneously adjust the back cushion's length and angle using a single operating mechanism, improving not only adjustment efficiency but also stability and safety during use. This innovative design will enable the dumbbell bench to meet diverse training needs while further optimizing the user experience, bringing a more efficient and convenient experience to fitness enthusiasts.
