Description

Technical Field

[0001] This utility model relates to the field of exercise equipment technology, and in particular to a cylindrical air-compressed fitness device. Background Technology

[0002] With the vigorous development of my country's sports industry, existing strength training equipment is basically divided into two categories: weight and elasticity. Due to their weight, they can only be installed in specific environments. The training programs of strength training equipment are fixed and monotonous, resulting in limited training content and high prices. Furthermore, existing sports equipment pre-sets the force of the exercise, and the person passively receives the set force. In addition, both weight and elasticity equipment have uncontrollable reverse forces, and the resulting reverse impact forces have adverse effects on the human joints, ligaments and muscles. Utility Model Content

[0003] The purpose of this invention is to provide a cylindrical air-compressed fitness device that solves the problems of fitness equipment being difficult to carry, requiring a large space, having limited training programs, and causing injuries due to reverse force.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] The cylindrical air-compressed fitness device includes a slotted cylinder with a different diameter. There is a straight slot in the axial direction from the top to the bottom of the cylinder, through which the multi-functional piston handle ring slides. The top opening of the slotted cylinder has threads on the outside, which are screwed together with the top cover for sealing. The bottom end of the cylinder is a right-angled inward-curving cylinder opening, and its radial inner edge is provided with a fixing mortise for fixing the bottom cover and the different diameter fixing sleeve.

[0006] The slot reinforcement sleeve has a slot tenon that matches the slot, which fits into the slot to make the slotted cylinder complete and can be screwed onto the top cover. The top inner edge of the slot reinforcement sleeve has a first mounting groove, in which the ring on the top side of the first ring airbag is placed and fixed by the top airbag fixing ring. The bottom edge of the slot tenon has a detachable slot sealing strip fixing stud.

[0007] The slot seal of the cylindrical air-operated fitness device is a long strip wider and longer than the slot itself. It has slot seal fixing holes at both ends. The top hole is attached to the slot seal fixing stud below the slot latch, while the bottom hole passes through the slot seal channel on the multi-functional piston and is attached to the slot seal fixing post on the bottom cover's non-diameter fixing sleeve. The slot seal seals the slot when the multi-functional piston slides, preventing the airbag from expanding and overflowing the slot.

[0008] The bottom cover fixing sleeve of the cylindrical air-compressed fitness device is an internal sleeve with an adjustable diameter. A sealing strip and fixing stud are provided at the top of the sleeve. The outer side of the short diameter fixing sleeve of the bottom cover has a fixing tenon that fits into the inner edge of the cylindrical tube with the adjustable diameter hole. The bottom end of the bottom cover fixing sleeve has a fourth mounting groove in which the ring of the second annular air bladder is placed and fixed by the bottom air bladder fixing ring. The outer side of the short diameter fixing sleeve of the bottom cover has threads that screw into the bottom cover.

[0009] The top and bottom covers of the cylindrical air-compressed fitness machine have internal threads and sealing rings, which can be screwed together with a slotted cylinder of different diameters. The top cover has an air inlet hole in the center, and the bottom cover has a bottom cover fixing ring on the outer side of the center.

[0010] The multi-functional piston of the cylindrical air-compressed fitness device is divided into two parts. The upper part includes a handle ring and a balance plate. A cylindrical seam sealing channel is provided between the balance plate and the handle ring. Pressure sensors are located at both ends of the balance plate, and electronic control transmission devices and a rechargeable battery are located on the bottom and top. The lower part of the multi-functional piston includes a piston air vent plate located below the balance plate. The piston air vent plate has a second mounting groove and a third mounting groove on both the top and bottom sides. The annular openings of the first and second annular air bladders are installed in the grooves and fixed by the annular air bladder ring fixing straps. The piston air vent plate has an air vent adjustment plate gear shaft mounting hole in the center. The vent adjustment plate gear shaft is a segmented gear shaft, the piston vent plate segment is cylindrical, and the vent adjustment plate segment is hexagonal with fixing pin holes at the hexagonal edges. The piston vent plate and the vent adjustment plate are fixed by rotation of the gear shaft. The gear of the vent adjustment plate gear shaft meshes with the gear of the vent adjustment motor. There are two vents on the vent adjustment plate, namely a fixed vent and an adjustment vent. The vent cover plate covers the fixed vent. The vent cover plate spring presses the gear shaft on one side and presses the cover plate on the other side. There is an electromagnetic switch on the bottom side of the piston vent plate, which together control the airflow pressure between the first ring vent and the second ring vent.

[0011] The top and bottom sides of the multi-functional piston of the cylindrical air-compressed fitness device have a first annular air bladder and a second annular air bladder, which communicate with the top cover and bottom cover through air holes on the multi-functional piston.

[0012] When the air in the air bladder of a cylindrical air-compressed fitness device is insufficient, air can be added through the air inlet to maintain a suitable air pressure inside the air bladder.

[0013] The single suction cup pull plate can be connected to a pull ring, which connects the suction cup handle to a cylindrical air-operated fitness device or auxiliary device to maintain a stable suction force.

[0014] The suction cup assembly pull plate has a pull ring in the center, which makes the suction force of the suction cup stable and concentrated. Select a flat and smooth ground, arrange the suction cups in position, install the suction cup assembly pull plate, fix the suction cups under the suction cup assembly pull plate, and fix them by the suction cup handle pressure plate. Then connect to the cylindrical air-compressed fitness device or auxiliary device through the connecting pull ring.

[0015] The hip and waist support rod has openings and connecting holes at both ends, allowing it to be directly connected to the handle ring of the multi-functional piston, or connected using a connecting ring. A tension ring for the hip and waist support belt is located above the upper midpoint of the hip and waist support rod.

[0016] The waist and hip fixation belt is shaped like an "I". The upper horizontal section is the waist fixation belt, the lower horizontal section is the hip fixation belt, and the middle section between the horizontal and vertical sections is a rigid hip fixation belt to prevent the waist and hip fixation rod from injuring the coccyx. The bottom edge of the vertical section has a connecting ring that connects to the waist and hip fixation rod so that the body can move freely.

[0017] The lumbar support stool is an auxiliary stool with multiple degrees of freedom of movement. There is a connecting ring at the end of the stool surface, which connects to the waist and hip fixing belt ring to prevent the body from shifting forward. The stool legs are I-shaped, with a set of front stool legs extending forward to increase the range of hand movement.

[0018] The directional frame is fixed at an appropriate position on the front leg of the backrest bench to regulate and limit the range of motion of the cylindrical air-assisted exercise machine and the direction of the handle ring, so as to prevent the cylindrical air-assisted exercise machine from contacting the head and body.

[0019] The auxiliary rod is used in conjunction with the tripod fixing component to form a stable upright tripod with the suction cup assembly, providing an auxiliary support for vertical movement on the cylindrical air-operated fitness machine.

[0020] The auxiliary devices, such as the bow handle, string ring, chest and back grip, as well as the special wrist and foot rings, are used in conjunction with the cylindrical air-compressed fitness machine for various exercises and rehabilitation training.

[0021] Insufficient air inside the cylinder of a cylindrical air-compressed fitness machine can lead to reduced strength and empty strokes. Use an air pump to replenish air in time to maintain normal use.

[0022] The beneficial effects of this utility model are:

[0023] This utility model is small in size, light in weight, easy to carry, easy to install, and convenient to use. It can be used for all-round muscle training and is not limited by the environment. It can be popularized in the home and can even be used in weightless space capsules for activities such as archery, chest, back and arm strength training, hand grip strength training, leg muscle training, Tai Chi cloud hands training, and swimming.

[0024] This utility model consists of two ring-shaped airbags, each formed by a multi-functional piston, a top cover, and a bottom cover, creating two sealed air cylinders. When the multi-functional piston is pulled, the airflow pressure generated by the air holes forms the motion force, which increases or decreases with the amount of force applied. The motion force is controlled by the user, and the air hole adjustment plate can be adjusted to suit the pressure. It is suitable for all ages and for rehabilitation exercises for the elderly.

[0025] This invention has a unidirectional force function and can also be used for bidirectional force training. The magnitude of the force is controlled by the user. The greater the force applied, the greater the force generated; the less the force applied, the less the force generated. Moreover, there is no reverse force, so it will not cause injury to the body.

[0026] This utility model of a cylindrical air-compressed fitness device, in conjunction with auxiliary devices, can perform a combination of training programs for various muscle strengths, technical movements, and rehabilitation. Attached Figure Description
