Description

Technical Field

[0001] The present application belongs to the technical field of fitness equipment, and more specifically, to a kettlebell that is easy to maintain. Background Art

[0002] In the context of national fitness, many outdoor public places provide kettlebells for free use. Nowadays, such kettlebells for outdoor use are usually put on vertical rails, and brake clamps are provided inside the kettlebells to clamp the rails. When the operator holds the kettlebell, the brake handle will be triggered, so that the brake clamp will loosen the rails, so that the kettlebell can move up and down freely, and the operator can carry out normal training; when the operator accidentally releases the kettlebell, the brake clamp automatically clamps the rails, reducing the speed of the kettlebell's fall, or even directly fixes the kettlebell on the rails, thereby avoiding hitting the operator.

[0003] After long-term use, the friction plate of the brake clamp of the current kettlebell is prone to wear, resulting in a decrease in braking ability, and therefore needs to be replaced in a timely manner.

[0004] However, current kettlebells were not designed with friction plate replacement in mind. Therefore, to replace the friction plate, the kettlebell must be removed from the guide rail and then opened for replacement. The entire process is time-consuming and laborious. Utility Model Content

[0035] Please also read Figure 1 and Figure 2 The kettlebell for easy maintenance provided by the embodiment of the present application is now described. A kettlebell for easy maintenance includes: a main body, a brake clamp and two friction plates.

[0036] The main body is provided with a sliding hole that passes through from top to bottom and is suitable for the guide rail to pass through; a maintenance port is also provided at the bottom of the main body, and the maintenance port is closed by a detachable bottom cover; the brake clamp is arranged inside the main body and has two clamping ends; two friction plates are arranged at the two clamping ends respectively; the friction plate includes a fixed part and a friction part, the friction part is located on the side of the clamping end facing the guide rail and is suitable for contacting and rubbing with the guide rail, and the friction plate is detachably fixed to the clamping end through the fixed part; the fixed part is located at the bottom of the clamping end and is opposite to the maintenance port. After the bottom cover is separated from the main body, the fixed part is exposed through the maintenance port, and the maintenance port is suitable for the friction plate to pass through.

[0037] Compared with the prior art, the kettlebell of the embodiment of the present application is easy to maintain. By designing the friction plate such that the friction part is fixed to the clamping end through the fixing part, the entire friction plate can be removed by removing the fixing part; the fixing part is located at the bottom of the clamping end, and the friction part is located on the side of the clamping end facing the guide rail, which not only ensures that the friction part can better contact and rub with the guide rail, but also enables the fixing part to be opposite to the maintenance port, so that the friction plate can be easily removed through the maintenance port;

[0038] Moreover, when the friction part contacts the guide rail, the friction part is subjected to an upward friction force, and the fixing part is located at the bottom of the clamping end, which can make the connection force between the friction skin and the clamping end more reasonable and the connection more firm;

[0039] The friction plate is designed so that the fixed part is opposite to the bottom cover. During later maintenance, the bottom cover is opened to expose the fixed part from the maintenance port, and the friction plate can be easily replaced through the maintenance port. Moreover, the bottom cover is designed at the bottom of the main body so as not to affect the main appearance of the kettlebell.

[0040] In this embodiment, the shape of the main body can refer to the common kettlebell shape on the market. A sliding hole is set in the middle of the main body so that it can be sleeved on the vertical guide rail, and a linear sliding bearing can be installed in the sliding hole. Brake clamps, friction plates and other structures can be installed in the inner cavity of the main body, and a maintenance port is opened at the bottom. The bottom cover is detachably installed at the bottom of the main body by bolts.

[0041] The specific structure of the brake clamp can refer to other publicly known kettlebells, and can also adopt the structure of other embodiments of the present application. The two friction plates are respectively installed at the two clamping ends. When the brake clamp is actuated, the guide rail passing through the slide hole is clamped by the two friction plates.

[0042] The fixing part and the friction part of the friction plate are connected together at an angle, the fixing part is fixedly attached to the bottom of the clamping end, and the friction part is fixedly attached to the clamping end facing one side of the guide rail. The fixing part and the clamping end can be detachably fixed by bolts or clamping.

[0043] See also Figure 2 As a specific embodiment of the kettlebell that is easy to maintain provided in the present application, the friction plate includes an L-bottom plate and a friction block.

[0044] The first end of the L-bottom plate forms a fixing portion, and the second end extends to the friction portion; the friction block is arranged at the second end of the L-bottom plate to form the friction portion.

[0045] In this embodiment, the L-bottom plate ensures the connection strength between the fixing part and the friction part, and the friction block increases the friction force with the guide rail.

[0046] In specific implementation, the L bottom plate can be made of a steel plate bent into a right angle. The friction block can be made of hard rubber material and fixed on the second end of the L bottom plate by bolts.

[0047] See also Figure 2 As a specific embodiment of the kettlebell that is easy to maintain provided by the present application, a mounting groove is provided at the clamping end, and the mounting groove extends from the bottom surface of the clamping end to one side of the surface guide rail; the L-bottom plate is installed in the mounting groove, and the end surface of the first end and the end surface of the second end of the L-bottom plate are respectively limited by the inner walls at both ends of the mounting groove.

[0048] In this embodiment, the two ends of the L-bottom plate are positioned by the mounting grooves, so that the friction plate can be accurately mounted on the clamping end and the position of the friction plate can be kept firmly.

[0049] In a specific implementation, the mounting groove is arranged at a corner of the clamping end, which may be approximately at a right angle, with one end located at the bottom surface of the clamping end and the other end located at one side of the clamping end surface guide rail.

[0050] See also Figure 2 As a specific embodiment of the kettlebell that is easy to maintain provided in the present application, a limiting hole is provided on the end face of the second end of the L-bottom plate, and a clamp inserted into the limiting hole is provided on the end face corresponding to the mounting groove.

[0051] In this embodiment, the first end of the L-base plate forms a fixing portion fixed to the clamping end, and the second end of the L-base plate is fixed to the clamping end through a clamp and a limiting hole, so that both ends of the L-base plate are fixed to the clamping end, thereby improving the stability of the friction plate.

[0052] See also Figure 1 and Figure 2 As a specific embodiment of the kettlebell provided by the present application for easy maintenance, the first end of the L-bottom plate is fixed to the clamping end by a fixing bolt, and the bolt head of the fixing bolt faces the maintenance port. In this embodiment, it is convenient to use a screwdriver to screw the fixing bolt through the maintenance port to remove the friction plate.

[0053] See also Figure 1 As a specific embodiment of the kettlebell that is easy to maintain provided by the present application, the bottom cover is provided with a bottom hole suitable for the guide rail to pass through, and a linear sliding bearing is provided in the bottom hole.

[0054] In this embodiment, the bottom cover is matched with the guide rail through a linear sliding bearing, so that the kettlebell can slide more smoothly.

[0055] See also Figure 1 As a specific embodiment of the kettlebell that is easy to maintain provided by the present application, the brake clamp includes two clamp arms and two brake handles.

[0056] The two clamp arms are respectively located on both sides of the slide hole; each clamp arm is rotatably arranged, and one end close to the slide hole forms a clamping end, and the other end is a linkage end; the respective touching ends of the two brake handles respectively drive the linkage ends of the two clamp arms, and the respective operating ends are respectively located in the holding space of the two kettlebell handles. When the operator holds the kettlebell handle, he touches the operating end of the brake handle, and the brake handle drives the clamp arm to rotate, so that the friction plate releases the guide rail.

[0057] In a specific implementation, the clamp arm is installed inside the main body through a rotating shaft, the shorter end of the clamp arm is close to the sliding hole to form a clamping end, and the longer end is away from the sliding hole to form a linkage end. The brake handle is arranged to slide up and down, the operating end is located outside the main body, and the touch end is located inside the main body. Specifically, the brake handle can slide up and down through a vertical slide slot slider structure or a slide rail slider structure.

[0058] When the operator's hand extends into the gripping space of the kettlebell handle, the operating end of the brake handle is pressed down, so that the actuating end of the brake handle presses down the linkage end of the clamp arm, thereby causing the clamping end of the clamp arm to rotate upward and the friction plate to release the guide rail.

[0059] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
