Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically a self-locking structure for a telescopic rowing mechanism. Background Technology

[0002] Rowing machines, also known as rowing apparatus, are a type of fitness equipment designed to allow users to simulate real rowing motions, providing a full-body workout. They typically include a seat that slides along a track, a handle or bar for pulling, and a set of foot pedals on which the user's feet are secured. Resistance can be generated in various ways, such as electrical resistance, water resistance, air resistance, magnetic resistance, or hydraulic resistance.

[0003] A locking handle for a rowing machine, disclosed in Chinese Patent Publication No. CN215231886U, includes a base and a seat. The base has a first slide rail and a second slide rail. The first slide rail and the second slide rail are slidable left and right relative to the base. The seat is positioned on the second slide rail. A locking handle is provided on the first slide rail, and the second slide rail has a locking part adapted to the locking handle. The rowing machine extends and retracts via the first and second slide rails, and the second slide rail is locked in place by the locking handle. The first slide rail is also locked in place by an external foot pedal. However, when the foot pedal is retracted inside the fitness equipment, it is difficult to simultaneously secure both the first and second slide rails with the locking handle.

[0004] The existing telescopic rowing mechanism is not convenient to lock and fix the first and second slide rails at the same time during use, which reduces the convenience of installation and increases the difficulty of operation, thus raising the threshold for use. Utility Model Content

[0005] The purpose of this utility model is to provide a self-locking structure for a telescopic rowing mechanism, which has the advantage of being easy to operate. It solves the problem that existing telescopic rowing mechanisms are not convenient to lock and fix the first and second slide rails at the same time during use, which reduces the convenience of installation and increases the difficulty of operation, raising the threshold for use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a self-locking structure for a telescopic rowing mechanism, comprising a first slide rail, a second slide rail movably connected to the inner side of the first slide rail, a locking rod assembly installed on the inner side of the first slide rail, and the locking rod assembly simultaneously locking the first slide rail and the second slide rail when the first slide rail and the second slide rail are extended.

[0007] As a preferred embodiment of the self-locking structure of the telescopic rowing mechanism of this utility model, the first slide rail includes a first frame, pulleys and rods are installed on the front and rear sides of the first frame, and a first track is fixedly connected to the inner side of the first frame.

[0008] As a preferred embodiment of the self-locking structure of the telescopic rowing mechanism of this utility model, the first frame has a through hole and the rod has a first slot.

[0009] As a preferred embodiment of the self-locking structure of the telescopic rowing mechanism of this utility model, the second slide rail includes a second frame, with a second track fixedly connected to the front and rear sides of the second frame, and a double-headed sliding sleeve slidably connected to the surface of the second track. The double-headed sliding sleeve is fitted onto the surface of the first track and slidably connected to it.

[0010] As a preferred embodiment of the self-locking structure of the telescopic rowing mechanism of this utility model, a locking device is fixedly connected to one end of the second frame near the first frame.

[0011] As a preferred embodiment of the self-locking structure of the telescopic rowing mechanism of this utility model, the locking component includes a locking component body, which is installed on the second frame. The locking component has a locking head and a positioning head on one side. The locking head has a second locking groove, and the positioning head is equipped with an elastic positioning pin, which is movably connected to the first frame.

[0012] As a preferred embodiment of the self-locking structure of the telescopic rowing mechanism of this utility model, the locking rod assembly includes a first locking rod, one end of which is fixedly connected to a second locking rod. When locking the first slide rail and the second slide rail, one end of the second locking rod extends through the through hole into the first slot, and one end of the first locking rod is locked in the second slot.

[0013] As a preferred embodiment of the self-locking structure of the telescopic rowing mechanism of this utility model, the first locking rod surface is movably fitted with a first limiting sleeve and a second limiting sleeve, and the second locking rod surface is movably fitted with a third limiting sleeve. The first limiting sleeve, the second limiting sleeve and the third limiting sleeve are fixedly installed on the inner wall of the first frame.

[0014] As a preferred embodiment of the self-locking structure of the telescopic rowing mechanism of this utility model, a fixing ring is fixedly sleeved on the surface of the first locking rod, and a spring is movably sleeved on the surface of the first locking rod. The spring is located at the end opposite to the second limiting sleeve and the fixing ring. A limiting pin is installed on the surface of the first locking rod, and the limiting pin is movably connected to one end of the second limiting sleeve.

[0015] As a preferred embodiment of the self-locking structure of the telescopic rowing mechanism of this utility model, a handle is fixedly connected to one end of the first locking rod, and the handle is located on one side of the locking head.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. The self-locking structure of this utility model provides high flexibility and stability, greatly enhancing the user experience. First, the design allows users to easily expand the rowing machine from a compact, folded state to a fully extended working state, while ensuring it remains stable during use. By adopting a dual-rail system and corresponding locking rod components, not only is space effectively utilized, but the stability and safety of the equipment are also guaranteed during high-intensity training. In addition, the design of the pulleys in contact with the ground reduces friction during movement, making the entire device smoother during unfolding or folding, and facilitating single-person operation.

[0018] 2. The self-locking mechanism of this utility model significantly enhances the convenience and safety of use. The spring and limit sleeve in the locking rod assembly work together to ensure the reliability of the locking process and effectively prevent the possibility of accidental unlocking. At the same time, the setting of the card and elastic positioning pin further strengthens the locking of the second slide rail position and avoids any loosening or shaking that may affect the exercise experience. Overall, this design not only optimizes the user's operating experience, but also greatly improves the overall safety performance of the fitness equipment. Attached Figure Description

[0027] Please see Figures 1-7 A self-locking structure for a telescopic rowing mechanism includes a first slide rail 1, a second slide rail 2 movably connected to the inner side of the first slide rail 1, and a locking rod assembly 3 installed on the inner side of the first slide rail 1. When the first slide rail 1 and the second slide rail 2 are extended, the locking rod assembly 3 simultaneously locks the first slide rail 1 and the second slide rail 2.

[0028] Furthermore, the first slide rail 1 is movably installed inside the fitness cabinet 4. When the first slide rail 1 and the second slide rail 2 are stored, the second slide rail 2 enters into the first slide rail 1, and then the first slide rail 1 and the second slide rail 2 enter into the fitness cabinet 4.

[0029] Furthermore, when the first slide rail 1 and the second slide rail 2 are unfolded, the second slide rail 2 is pulled out from inside the first slide rail 1, and the first slide rail 1 is pulled out from inside the fitness cabinet 4.

[0030] Furthermore, a foot pedal assembly 5 is installed on the first slide rail 1, and a seat cushion assembly 6 is installed on the second slide rail 2.

[0031] Furthermore, the first slide rail 1 includes a first frame 101, with pulleys 102 and rods 103 installed on the front and rear sides of the first frame 101, and a first track 104 fixedly connected to the inner side of the first frame 101.

[0032] Furthermore, a through hole 105 is provided on the first frame 101, and a first slot 106 is provided on the rod 103.

[0033] Furthermore, the pulley 102 is rotatably connected to the first frame 101, and the pulley 102 moves on the ground to support the bottom of the first frame 101.

[0034] Furthermore, the rod 103 is fixedly installed on the inner wall of the fitness cabinet 4, and the rod 103 is slidably connected to the first frame 101 to limit the first frame 101 and prevent it from swaying back and forth.

[0035] Furthermore, the second slide rail 2 includes a second frame 201, with a second track 202 fixedly connected to the front and rear sides of the second frame 201. A double-headed sliding sleeve 203 is slidably connected to the surface of the second track 202, and the double-headed sliding sleeve 203 is sleeved on the surface of the first track 104 and slidably connected to it.

[0036] Furthermore, a clip 204 is fixedly connected to one end of the second frame 201 near the first frame 101.

[0037] Furthermore, the card 204 includes a card body 205, which is mounted on the second frame 201. The card 204 has a card head 206 and a positioning head 208 on one side. The card head 206 has a second card slot 207, and the positioning head 208 is equipped with an elastic positioning pin 209. The elastic positioning pin 209 is movably connected to the first frame 101.

[0038] Furthermore, the first frame 101 is provided with a positioning hole that works in conjunction with the elastic positioning pin 209. One end of the elastic positioning pin 209 is provided with a positioning bead. After the positioning bead enters the positioning hole, it limits the second frame 201 and prevents the second frame 201 from detaching from the first frame 101.

[0039] Furthermore, the locking rod assembly 3 includes a first locking rod 301, one end of which is fixedly connected to a second locking rod 302. When locking the first slide rail 1 and the second slide rail 2, one end of the second locking rod 302 extends through the through hole 105 into the first slot 106, and one end of the first locking rod 301 is engaged in the second slot 207.

[0040] Furthermore, a first limiting sleeve 303 and a second limiting sleeve 304 are movably sleeved on the surface of the first locking rod 301, and a third limiting sleeve 305 is movably sleeved on the surface of the second locking rod 302. The first limiting sleeve 303, the second limiting sleeve 304 and the third limiting sleeve 305 are fixedly installed on the inner wall of the first frame 101.

[0041] Furthermore, a fixing ring 309 is fixedly sleeved on the surface of the first locking rod 301, and a spring 306 is movably sleeved on the surface of the first locking rod 301. The spring 306 is located at the opposite end of the second limiting sleeve 304 and the fixing ring 309. A limiting pin 307 is installed on the surface of the first locking rod 301, and the limiting pin 307 is movably connected to one end of the second limiting sleeve 304.

[0042] Furthermore, a handle 308 is fixedly connected to one end of the first locking rod 301, and the handle 308 is located on one side of the locking head 206.

[0043] Furthermore, the first locking rod 301 and the second locking rod 302 are "L" shaped, and the first locking rod 301 and the second locking rod 302 are combined together to form a "Z" shape.

[0044] Furthermore, the second limiting sleeve 304 is provided with a storage groove that works in conjunction with the limiting pin 307. When the first slide rail 1 and the second slide rail 2 are unlocked, the first locking rod 301 and the second locking rod 302 are rotated upwards, causing the limiting pin 307 to rotate to the storage groove. At this time, the spring 306 drives the fixing ring 309 and the first locking rod 301 to move to the right, bringing the limiting pin 307 into the storage groove. The storage groove limits the limiting pin 307, preventing the first locking rod 301 and the second locking rod 302 from rotating on their own.

[0045] When the rowing mechanism needs to be deployed, the second frame 201 is pulled outward. The second frame 201 drives the second track 202 to slide inside the double-headed sliding sleeve 203. When the second track 202 moves to its limit position, it engages with the double-headed sliding sleeve 203 and drives the double-headed sliding sleeve 203 to slide on the surface of the first track 104, thereby completely moving the second frame 201 to the outside. When the double-headed sliding sleeve 203 moves to its limit position, it engages with the first track 104, moving the first track 104 and the first frame 101 to the outside. During the movement of the first frame 101, it slides on the ground through the pulley 102, and the rod 103 limits the movement of the first frame 101. When the first slide rail 1 and the second slide rail 2 are completely pulled out, the locking rod assembly 3 locks the first slide rail 1 and the second slide rail 2 simultaneously.

[0046] During the use of the locking rod assembly 3, the first locking rod 301 is rotated downwards, and the head of the first locking rod 301 is locked in the second slot 207 to lock and fix the card head 206, the card body 205 and the second frame 201, preventing the second frame 201 from moving. The downward rotation of the first locking rod 301 drives the second locking rod 302 to rotate upwards. The second locking rod 302 passes through the through hole 105 and enters the first slot 106 to connect the first frame 101 and the rod body 103, preventing the first frame 101 from moving. After locking is completed, the spring 306 presses against the fixing ring 309, and the limiting pin 307 is locked at one end of the second limiting sleeve 304, applying pressure to the first locking rod 301 to prevent it from rotating loosely.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
