Technical Field

[0001] The utility model relates to the field of barbell plates, in particular to a barbell plate with a fixing function. Background Art

[0002] Barbell is a common fitness equipment used for weightlifting training, exercising upper limb muscles and core strength. The structure of the barbell is not complicated. It mainly consists of a barbell rod and barbell plates symmetrically installed at both ends of the barbell rod.

[0003] In a common barbell in the prior art, a barbell plate is sleeved on the outer end of a barbell rod and fixed to the outer end of the barbell rod by a clamp. Therefore, the barbell plate itself does not have a fixing function, which may cause the barbell plate to loosen during use.

[0004] In order to solve the above problems, barbell plates with a fixing function have appeared in the prior art, such as a barbell plate with a fixing function disclosed in publication number CN110496360B, which utilizes negative pressure to cause the barbell plate to be adsorbed on the outer end of the barbell rod.

[0005] However, in actual use, multiple barbell plates are sometimes installed at one end of the barbell bar at the same time. If each barbell plate is connected to a negative pressure by pumping air during the installation process, the connection process will be too cumbersome. Utility Model Content

[0006] In response to the shortcomings of the existing technology, the present invention provides a barbell plate with a fixing function. The innermost barbell plate body is fixed to the barbell rod by adsorption through a fixing ring, and then the screw is rotated to drive the pressure plate to move, and the other barbell plate bodies are clamped and fixed to the innermost barbell plate body. There is no need to adsorb and fix all the barbell plate bodies to the barbell rod one by one. The fixing method is faster and simpler, and can effectively solve the problems in the background technology.

[0007] To achieve the above-mentioned object, the technical solution adopted by the present invention is as follows: a barbell plate with a fixing function includes a barbell plate body, a fixing ring is provided at the center of the barbell plate body, the barbell plate body is fixed to the barbell bar by adsorption through the fixing ring, and a plurality of split fixing components are provided at the outer end of the barbell plate body;

[0025] To make the technical means, creative features, objectives, and effects of the present invention easier to understand, the present invention will be further described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0026] In order to address the shortcomings of existing technologies, such as Figure 1-5 As shown, the utility model provides a barbell plate with a fixing function, including a barbell plate body 1, a fixing ring 3 is provided at the center of the barbell plate body 1, and the barbell plate body 1 is fixed to the barbell rod by adsorption through the fixing ring 3, and a plurality of split fixing components 2 are provided at the outer end of the barbell plate body 1;

[0027] The split fixing assembly 2 includes a detachable fixing seat 201 provided at the outer end of the barbell plate body 1, two slide bars 205 passing through the fixing seat 201, and a screw 202 passing through the fixing seat 201 and connected to the fixing seat 201 by a threaded connection is provided between the two slide bars 205;

[0028] The front and rear sides of the fixing seat 201 are respectively provided with an end plate 204 and a pressure plate 206 . The pressure plate 206 and the end plate 204 are connected by a sliding rod 205 . The rear end of the screw rod 202 is movably connected to the end plate 204 via a rotating shaft.

[0029] A knob 203 is fixedly provided at the front end of the screw rod 202 , and rotating the knob 203 can drive the screw rod 202 to rotate.

[0030] During use, the barbell plate body 1 is adsorbed and fixed to the outer end of the barbell rod through the fixing ring 3. When two or more barbell plates are fixed to one end of the barbell rod at the same time, the innermost barbell plate body 1 is adsorbed and fixed to the barbell rod using the fixing ring 3, and the split fixing component 2 is installed on the outer end of the barbell plate body 1, so that the barbell plate bodies 1 of other barbell plates are located between the pressure plate 206 and the innermost barbell plate body 1, and then the knob 203 is turned to drive the screw rod 202 to rotate, thereby driving the slide rod 205 Sliding on the fixing seat 201, the pressure plate 206 approaches the innermost barbell plate body 1 and clamps the other barbell plate bodies 1 between the pressure plate 206 and the innermost barbell plate body 1, thereby fixing all the barbell plates to the outer end of the barbell rod. In this way, only the innermost barbell plate body 1 is fixed, and the other barbell plate bodies 1 are fixed by the split fixing component 2 at the outer end of the barbell plate body 1. It is not necessary to adsorb and fix all the barbell plate bodies 1 to the barbell rod one by one, and the fixing method is faster and simpler.

[0031] In order to fix the barbell plate body 1 on the outer end of the barbell rod by adsorption, Figure 1 、 3 As shown in Figure 5, a cavity 8 is opened inside the fixing ring 3, and an air guide tube with a valve is fixed to the outer end of the fixing ring 3. One end of the air guide tube is connected to the cavity 8. The air inside the cavity 8 can be extracted through the air guide tube to generate negative pressure inside the cavity.

[0032] An annular groove 9 communicating with the cavity 8 is formed on the inner side of the fixing ring 3 , and a sealing ring 10 in contact with the barbell rod is fixed on the inner wall of the fixing ring 3 , and the sealing ring 10 plays a sealing role.

[0033] The barbell plate body 1 is fixed with a plurality of rubber protrusions 4 on both the front and rear sides. The rubber protrusions 4 allow the barbell plate body 1 to be separated from the ground or other barbell plate bodies 1 by gaps when it is laid flat, making it easy to carry.

[0034] The fixing ring 3 is placed on the outer end of the barbell rod so that the sealing ring 10 inside the fixing ring 3 is in close contact with the outer end of the barbell rod. Then, the air inside the cavity 8 is extracted through the air duct, and negative pressure is generated inside the cavity 8. The fixing ring 3 is adsorbed and fixed to the outer end of the barbell plate through the annular groove 9, thereby fixing the entire barbell plate body 1.

[0035] In order to fix the split fixing assembly 2 to the outer end of the barbell plate body 1, as shown in FIG. Figure 3 、 4 As shown, an external channel 11 is fixedly provided at the outer end of the fixing ring 3 , one end of the external channel 11 is communicated with the cavity 8 , and the other end of the external channel 11 extends to the outer end of the barbell plate body 1 .

[0036] An extension rod 6 is fixed to the bottom end of the fixing seat 201. When the split fixing assembly 2 is in use, one end of the extension rod 6 is inserted into the external channel 11 and fixed with a rubber head 7. The outer end of the rubber head 7 contacts the inner wall of the external channel 11, thereby adsorbing and fixing the fixing seat 201 to the outer end of the barbell plate body 1, thereby fixing the entire split fixing assembly 2;

[0037] After the split fixing assembly 2 is disassembled, a sealing plug 5 is provided at the open end of the external channel 11 , which can seal the external channel 11 after the split fixing assembly 2 is disassembled, thereby ensuring the sealing of the cavity 8 .

[0038] When the split fixing assembly 2 is not in use, the external channel 11 is closed with the sealing plug 5, and the cavity 8 is closed, which does not affect the adsorption and fixing function of the fixing ring 3. When the split fixing assembly 2 is needed, the sealing plug 5 at the external channel 11 is removed, and the extension rod 6 and the rubber head 7 at the bottom end of the fixing seat 201 are inserted into the external channel 11. The rubber head 7 can also close the external channel 11. In this way, while negative pressure is generated inside the cavity 8 to adsorb the barbell bar, the negative pressure can also adsorb the extension rod 6 and the rubber head 7 through the external channel 11 to achieve fixation of the split fixing assembly 2.

[0039] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
