[0002] For office workers, many choose to go to the gym for systematic fitness. Currently, there are more and more air resistance fitness products on the market, but most air resistance fitness equipment cylinders cannot lock quickly. When users are exhausted or release the exercise attachments, there is a risk of injury and equipment damage.

[0003] In conclusion, improving the safety of pneumatic fitness equipment is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The core of this utility model is to provide a cylinder locking mechanism. This cylinder locking mechanism can prevent the cylinder output end from extending rapidly through the setting of the brake component, thereby preventing the user from being pulled down by the reaction force of the rope due to exhaustion during exercise, thus improving the safety of the pneumatic fitness equipment.

[0029] Another core aspect of this invention is to provide a fitness equipment that includes the aforementioned cylinder locking mechanism.

[0030] It should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", and "rear" is based on the orientation or positional relationship shown in the accompanying drawings and is only for the purpose of facilitating the description of this application and simplifying the description. It is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0031] This application provides a cylinder locking mechanism, comprising: a body 1, a cylinder 2, and a brake assembly 3;

[0032] Among them, body 1 is a fixed structure, and its position generally does not change;

[0033] Cylinder 2 is located on the machine body 1, and the output end of cylinder 2 can extend outside the machine body 1;

[0034] Brake assembly 3 is located on body 1. Brake assembly 3 is connected to the output end of cylinder 2 via safety belt 4. Brake assembly 3 is used to wind up safety belt 4 in the direction of retraction towards the output end of cylinder 2 and to lock safety belt 4 when safety belt 4 exceeds the preset pull-out speed.

[0035] Rope 5 is connected to the output end of cylinder 2.

[0036] For details, please refer to the appendix. Figure 1This is a schematic diagram of the cylinder locking mechanism in its first state. In this state, the output end of cylinder 2 is in its normally extended position, and the fixed end, i.e., the upper end, of cylinder 2 is located on the body 1. The brake assembly 3 is also located on the body 1. The brake assembly 3 is connected to the output end of cylinder 2 via the seat belt 4, and the brake assembly 3 always tends to retract the seat belt 4. However, generally speaking, the force exerted when the output end of cylinder 2 is extended is greater than the tension of the seat belt 4 (currently, only the vertical components of the two forces are considered). Therefore, when not in use, the cylinder locking mechanism is in the state shown in the attached diagram. Figure 1 In its first state, when a user needs to exercise, they can follow the path shown in the attached image. Figure 1 Pulling rope 5 vertically upwards will cause the output end of cylinder 2 to retract when the user's pulling force is large, until the output end of cylinder 2 can no longer retract, reaching the second state of the cylinder locking mechanism, as shown in the attached figure. Figure 2 As shown, during exercise, the user reciprocates by pulling rope 5, causing the cylinder locking mechanism to switch between the first and second states. When the user is exhausted, the rope 5 loses its tension. Since the force exerted when the output end of cylinder 2 extends is greater than the tension of the safety belt 4, the output end of cylinder 2 will extend. Meanwhile, the brake assembly 3 always exerts a tension on the safety belt 4 to retract it. Therefore, there is also a tension between the safety belt 4 and the output end of cylinder 2. This force can greatly buffer the extension of cylinder 2, or even lock it, thus preventing the user from being pulled down by the reaction force on rope 5 when exhausted, avoiding falls and injuries, reducing the risk of injury, and significantly improving the safety of the pneumatic fitness equipment.

[0037] In addition, this application also provides a second type of braking component 3 and its associated effects. Although the braking component 3 always has a winding effect on the seat belt 4, its winding force is relatively small, and the buffering effect of the seat belt 4 on the output end of the cylinder 2 can be directly ignored. When the user is exhausted, the output end of the cylinder 2 extends rapidly. At this time, the braking component 3 can directly lock the seat belt 4 and the output end of the cylinder 2, forcibly stopping the extension of the output end of the cylinder 2. Correspondingly, there will be no force on the user on the rope 5, so it can prevent the rope 5 from pulling the user down and improve safety. For the locked braking component 3, pulling the rope 5 again can unlock it.

[0038] It should be clarified that the effects of the two braking components 3 are not primary or secondary, and both fall under the protection scheme of this application.

[0039] Based on the above embodiment, a handle 6 is also included, which is located at the end of the rope 5 away from the cylinder 2.

[0040] Specifically, a handle 6 is provided at the upper end of the rope 5. Generally, the handle 6 and the rope 5 are fixedly connected to ensure structural stability and prevent them from separating during exercise, thus ensuring the safety of the fitness equipment. It should be noted that in this application, the middle part of the handle 6 is connected to the rope 5, and the handle 6 and the rope 5 are perpendicular to each other, so that the user can hold the handle 6 and reduce the difficulty of exerting force during exercise.

[0041] Optionally, the handle 6 can be coaxially set with the rope 5, which can be adjusted according to the specific usage of the fitness equipment.

[0042] Furthermore, it should be noted that the aforementioned measures prevent users from falling and getting injured when they are exhausted. With the addition of handle 6, even when the user is exhausted, the rope 5 will not pull on handle 6. As long as the user does not let go, handle 6 will not fall onto the machine body 1, thus avoiding damage to the fitness equipment. Even if the user does let go, handle 6 will only be affected by its own weight, greatly reducing the probability of damaging the fitness equipment.

[0043] Based on the above embodiment, a connecting seat 7 is also included. The connecting seat 7 is connected to the output end of the cylinder 2, the safety belt 4 is connected to the first end of the connecting seat 7, and the rope 5 is connected to the second end of the connecting seat 7.

[0044] Specifically, the connecting seat 7 is located at the output end of the cylinder 2 and is perpendicular to the output end of the cylinder 2. The connecting seat 7 is a strip-shaped or plate-shaped structure with a certain thickness and strength. The safety belt 4 is connected to the left side of the connecting seat 7, and the rope 5 is connected to the right side of the connecting seat 7. The connecting seat 7 has a certain length so that the safety belt 4, the cylinder 2 and the rope 5 can be evenly arranged to prevent mutual interference between the three and improve the service life of the mechanism.

[0045] Optionally, the connector 7 can be made of alloy or steel to ensure the structural strength of the connector 7.

[0046] Based on the above embodiment, the seat belt 4 is rotatably connected to the connecting seat 7.

[0047] Specifically, since the seat belt 4 is fixed to the body 1 and the lower end of the seat belt 4 is connected to the left end of the connecting seat 7, the angle between the seat belt 4 and the vertical direction is different when the cylinder locking mechanism is in the first state and the second state. Therefore, the rotational connection between the seat belt 4 and the connecting seat 7 can make the connection structure between the seat belt 4 and the connecting seat 7 more stable.

[0048] Optionally, the seat belt 4 and the connecting seat 7 can also be detachably connected to facilitate regular disassembly and maintenance.

[0049] Optionally, the safety belt 4 and the connecting seat 7 can also be fixedly connected to ensure the reliability of the structure.

[0050] In some embodiments, the fixed end of the cylinder 2 is rotatably connected to the body 1.

[0051] Specifically, the top of cylinder 2 is rotatably connected to the body 1, and the connection position between cylinder 2 and body 1 can be locked instantly to adjust the angle between cylinder 2 and body 1. Since the connecting seat 7 is fixedly connected to the output end of cylinder 2, the connecting seat 7 can be rotated synchronously when cylinder 2 is rotated, which makes it convenient for users to adjust according to their own force exertion during exercise.

[0052] Optionally, the cylinder 2 and the body 1 can be directly fixedly connected, simplifying the structure, reducing costs, and ensuring structural reliability.

[0053] In some embodiments, the cylinder 2 and the brake assembly 3 are located on the same side of the connecting seat 7.

[0054] Specifically, as per the appendix to this application Figure 1 For example, cylinder 2 and brake assembly 3 are both located on the inner circumference of body 1, or on the same side. Due to the limited length of connecting seat 7, even if the output end of cylinder 2 reaches its maximum stroke, the seat belt 4 cannot be parallel to cylinder 2. Generally, the lower end of brake assembly 3 has an opening. When brake assembly 3 is set in the vertical direction, the seat belt 4 is prone to interference and friction with the opening of brake assembly 3. Therefore, body 1 needs to be set as a V-shaped structure. The included angle between the two ends of body 1 needs to be adjusted according to the length of connecting seat 7. More specifically, the longer the length between the connection position of the output end of cylinder 2 and connecting seat 7 and the connection position of seat belt 4 and connecting seat 7, the larger the included angle between the two ends of body 1. However, it should be noted that the maximum included angle between the two ends is generally 90°.

[0055] It should be further noted that in this application, the opening of the brake assembly 3 is angled downwards, and the output end of the cylinder 2 also extends downwards. However, this structure is not limited to this one orientation. In practical applications, the appendix to this application can be used... Figure 1 Or attach Figure 2 The structure can be used by rotating it 90° clockwise or counterclockwise, or by rotating it 180° directly and setting it on the gantry frame.

[0056] In some embodiments, the surface of handle 6 is roughened.

[0057] Specifically, since the handle 6 of this application is used in fitness equipment, it is necessary to increase the surface roughness of the handle 6 so that users can hold the handle 6 more stably during exercise and avoid slipping due to the low surface roughness of the handle 6, thereby improving safety.

[0058] It should be noted that improving the roughness of the handles of fitness equipment essentially increases controllable friction without injuring the hands. Surface machining can be used, such as knurling on the surface of handle 6, which can be formed in one step, at a low cost, and the depth of the texture can be adjusted; or a secondary coating can be made using rubber sleeves, heat shrink tubing, etc., which makes it more textured and can be easily replaced when used in the gym, making maintenance convenient. In gyms, a double-layer structure of knurling and rubber layer is preferred, balancing durability and comfort.

[0059] In some embodiments, the seat belt 4 is made of polyester fiber.

[0060] Specifically, the seat belt 4 in this application is based on a similar principle to car seat belts. The main webbing of car seat belts is almost exclusively made of polyester fiber. A few high-performance or special-needs models use nylon 66. Polyester fiber has a tensile strength range of 800–1100 MPa and an elongation at break of 10–14%. It can withstand 2–3 tons of instantaneous tensile force without breaking during a collision. It is wear-resistant, UV-resistant, moisture-resistant, and not prone to aging. Its lifespan can reach 10–15 years. The price is lower than that of nylon, which is conducive to large-scale cost reduction and is very suitable for use in gym equipment.

[0061] Based on the above embodiment, the surface of the body 1 is provided with usage markings.

[0062] Specifically, since the cylinder locking mechanism of this application is applicable to gym equipment, the surface of the structure should be marked with usage information so that users can directly access relevant equipment information.

[0063] In addition to the cylinder locking mechanism described above, this utility model also provides a fitness equipment that includes the cylinder locking mechanism disclosed in the above embodiments. For the structure of other parts of the fitness equipment, please refer to the prior art, which will not be described in detail here.

[0064] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0065] The cylinder locking mechanism and fitness equipment provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
