[0029] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0030] The technical solutions disclosed in various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0031] Please refer to Figure 1-4 The embodiment of the present application discloses a fixing device, which includes a first clamping part 100, a second clamping part 200 and an elastic part 300. The first end of the first clamping part 100 is rotatably connected to the first end of the second clamping part 200; the second end of the first clamping part 100 is connected to the second end of the second clamping part 200 through the elastic part 300, and the elastic part 300 is used to lock / unlock the first clamping part 100 and the second clamping part 200. The inner side of the first clamping part 100 is opposite to the inner side of the second clamping part 200.

[0032] When the fixing device is used on a barbell, the user can directly adjust the locking tension part 300 to lock or unlock the fixing device, thereby fixing the fixing device on the barbell or releasing it from the barbell. When the fixing device is in the locked state, the barbell plate on the barbell can be fixed within a specific range. During the entire use process, the user's operation is simple, and the clamping force of the fixing device is large.

[0033] In an optional embodiment of the present application, the elastic part 300 includes a handle 310 and a connector 320 that are rotatably connected, and the connector 310 is rotatably connected to the second end of the second clamping part 200. That is, the first clamping part 100, the second clamping part 200, the handle 310 and the connector 320 are rotatably connected in this way. It is used to achieve locking and unlocking by operating the handle 310. Among them, the rotational connection can be achieved by hinged connection. For example, the first ends of the first clamping part 100 and the second clamping part 200 are both provided with perforations, and pins are inserted into the perforations to achieve hinged connection. The rotational connection of other parts can also be achieved by this hinged method. In this way, when using the fixing device, the user can directly pry the handle 310 with his hands to lock or unlock the fixing device, which is very convenient to operate.

[0034] Furthermore, one end of the handle 310 connected to the connecting member 320 is a cylinder, and the rotating shaft between the handle 310 and the connecting member 320 deviates from the axis of the cylinder. When the elastic part 300 is in a locked state, the deviation direction is the direction away from the second end of the second clamping part 200, that is, the distance from the rotating shaft to the second end of the first clamping part 100 is greater than the distance from the axis of the cylinder to the second end of the first clamping part 100. In this way, the handle 310 can be fixed and the locking force and stability of the fixing device can be increased. When the elastic part 300 is in an unlocked state, the deviation direction is the direction close to the second end of the second clamping part 200, that is, the distance from the rotating shaft to the second end of the first clamping part 100 is less than the distance from the axis of the cylinder to the second end of the first clamping part 100, so that the unlocking function can be achieved.

[0035] Optionally, when the elastic part 300 is in a locked state, the shape of the handle 310 matches the shape of the outer side of the second clamping part 200. This can reduce the space occupied by the fixing device. In addition, in order to facilitate the user to open the handle 310, an inclined surface is provided at the end of the handle 310, and the inclined surface gradually moves away from the outer side of the second clamping part 200, so that a certain space can be formed between the handle 310 and the second clamping part 200, and the space is convenient for the user to insert the hand to open the elastic part 300. The certain space here can be a distance sufficient to accommodate the insertion of the user's fingers.

[0036] In an optional embodiment of the present application, the second end of the first clamping portion 100 is provided with a first groove 110, the opening of the first groove 110 is located at the end surface of the second end of the first clamping portion 100, and the first groove 110 is used to accommodate one end of the connector 320. Optionally, one end of the connector 320 is provided with a through hole in a direction perpendicular to the plane where the handle 310 rotates, and another through hole is provided at a position corresponding to the through hole in the first groove 110, and the latch passes through the through hole. The connector 320 can rotate along the latch. The opening width of the first groove 110 is greater than the width of the connector 320, so as to ensure that the connector 320 has a certain rotation space in the first groove 110.

[0037] Optionally, a second groove 210 is provided near the outer side of the second end of the second clamping portion 200, and the second groove 210 is used to accommodate the handle 310. The opening size of the second groove 210 increases toward the outside, so as to provide sufficient rotation space for the handle 310.

[0038] like Figure 4-5 As shown, optionally, the two sides parallel to the plane formed by the rotation of the second groove 210 and the elastic part 300 are provided with a limiter 220, and the sides corresponding to the handle 310 and the limiter 220 are provided with a slide groove 311, and the limiter 220 and the slide groove 311 are locked and slid. That is, the slide groove 311 is set at the end of the cylindrical end close to the handle 310. That is, the limiter 220 and the slide groove 311 can be switched between the locked state and the unlocked state through the sliding cooperation of the limiter 220 and the slide groove 311. In this way, through the cooperation of the limiter 220 and the slide groove 311, a rotation guide is provided for the handle 310, so that the rotation process is smooth, and the handle is limited to prevent the handle 310 from shaking left and right during the rotation process. Optionally, the limiter 220 can be a cylindrical pin, and the slide groove 311 can be an arc-shaped slide groove, and the inner arc of the arc-shaped slide groove faces the rotating shaft of the handle 310 and the connecting member 320. During the locking process, the limiter 220 slides in the slide groove 311 from the outer side to the inner side of the second clamping part 200; during the unlocking process, the limiter 220 slides in the slide groove 311 from the inner side to the outer side of the second clamping part 200. This can further make the rotation process smoother. Optionally, the width of the slide groove 311 is slightly larger than the diameter of the cylindrical pin, so that the stability and smoothness of the handle rotation can be taken into account.

[0039] Optionally, the outer sides of the first clamping portion 100 and the second clamping portion 200 are polygonal. Accordingly, the shape of the handle 310 is similar to a boomerang, so that when the fixing device is in a locked state, the handle 310 can match the outer side of the fixing device, that is, the two fit as closely as possible. Optionally, when the fixing device is in a locked state, the polygon formed on its outer side is an equilateral polygon.

[0040] like Figure 4 As shown, a through hole (230) is provided on one side of the end of the groove close to the second end of the second clamping portion 200, and the connecting member 320 passes through the through hole (230) and is connected to the handle 310. The size of the through hole (230) is to ensure the smooth rotation of the handle 310 and the movement of the connecting member 320.

[0041] In an optional embodiment of the present application, an anti-skid pad 400 is provided on the inner side of the first clamping portion 100 and the second clamping portion 200. In this way, when the fixing device is used to fix the dumbbell plate, the friction between the fixing device and the barbell bar is increased. Optionally, the anti-skid pad 400 is made of plastic material or other materials with a certain degree of flexibility, which increases the contact area between the fixing device and the barbell bar, thereby further increasing the friction between them, thereby improving the clamping force of the fixing device.

[0042] Optionally, the inner sides of the first clamping part 100 and the second clamping part 200 are semicircular, and when the first clamping part 100 and the second clamping part 200 are locked, the inner sides thereof form a cylindrical shape, so that the barbell can be better fitted, thereby increasing the clamping force of the fixing device.

[0043] Optionally, the end surface of the second end of the first clamping portion 100 and the end surface extension surface of the second end of the second clamping portion 200 pass through the center of their respective semicircles. In this way, the fixing device is more stable when locked.

[0044] At least one side of the first clamping portion 100 and the second clamping portion 200 perpendicular to the axis of the cylinder is provided with a magnetic member 500. Figure 2 The opposite side as shown and the back side. This allows the fixture to be attached to any magnet for easy storage.

[0045] in, Figure 1-4 The fixings are shown unlocked. Figure 5-6 The fastening device is shown in the locked position.

[0046] The embodiment of the present application also discloses a barbell, which includes the fixing device described in any of the above embodiments.

[0047] Here are the steps for using the fixture:

[0048] (1) Put the required barbell plates onto the barbell bar;

[0049] (2) Put the unlocked fixing device onto the barbell bar so that the fixing device is in contact with the barbell plates.

[0050] (3) Turn the handle to lock the fixing device.

[0051] It can be seen that the fixing device is easy to operate.

[0052] The above is only the embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Without departing from the scope of the present application's purpose and the claims, many forms and any modifications, equivalent substitutions, improvements, etc. made may also be made, all of which should be included in the scope of the claims of the present application.
