Description

Technical Field

[0001] The invention relates to the technical field of fitness equipment, in particular to a quick-assembly barbell plate. Background Art

[0002] The barbell is a common piece of fitness equipment. By placing plates of different weights on the barbell and combining them with corresponding special muscle strength training techniques, you can effectively perform muscle endurance training for muscle groups throughout the body.

[0003] Traditional barbell plates can only be slid in one by one from both sides of the barbell when in use or stored. If you need to take out the inner barbell plates separately, you need to remove all the outer barbell plates first, which makes the operation very time-consuming and laborious. In addition, the method of sliding in from both sides of the barbell also requires additional operating space during installation and storage, which is not conducive to saving space. Summary of the invention

[0004] The technical problem to be solved by the present invention is to solve the problem that the barbell plates on the barbell bar in the prior art are inconvenient to disassemble and assemble and a large disassembly and assembly space is required.

[0005] The technical solution of the present invention is: to provide a quick-assembly barbell plate, including a barbell plate body, a connecting rod assembly and a limit block, the barbell plate body is provided with a radially arranged through groove, the through groove includes a limit end located in the middle of the barbell plate body and a notch end extending through the outer edge of the barbell plate body, the limit block is rotatably connected to the barbell plate body and is located on the outside of the through groove, one end of the connecting rod assembly is movably connected to the barbell plate body and the other end is rotatably connected to the limit block, and the connecting rod assembly is used to push the limit block to rotate into the through groove to achieve locking of the barbell rod in the limit end.

[0006] The beneficial effects of the above scheme are as follows: by setting the through groove on the barbell plate body, the barbell plate body can be directly inserted and assembled on the barbell rod in the radial direction; then, the connecting rod assembly is used to push the limit block to rotate, so that the notch end of the through groove can be closed, and the barbell rod is locked between the limit end of the through groove and the limit block, and the installation is completed. Compared with the barbell plate installed from the side in the prior art, the barbell plate body of this scheme requires a small installation space, and each barbell plate body located on the inner side of the barbell rod can be independently disassembled and assembled, which is more convenient and practical than the traditional disassembly and assembly method of removing the barbell plates from the barbell rod one by one.

[0007] Preferably, a accommodating cavity is provided inside the barbell plate body, and the limit block and the connecting rod assembly are both located inside the accommodating cavity, thereby protecting the limit block and the connecting rod assembly and avoiding damage caused by bumps.

[0008] Preferably, the through groove is located at the lower part of the barbell plate, and the space of the accommodating cavity located at the upper part of the barbell plate is larger than the space located at the lower part of the barbell plate so that the center of gravity of the barbell plate is located at the lower part, thereby ensuring that after the user installs the barbell plate on the barbell bar, the center of gravity of all the barbell plates are located at the lower part, avoiding the offset problem caused by uneven weight, which not only ensures the exercise effect but also facilitates the disassembly and assembly of the barbell plate on the barbell bar.

[0009] Preferably, the upper side wall of the limiting end of the through groove is provided with an arc-shaped raised load-bearing portion, thereby compensating for the reduced strength of the connection portion between the barbell plate and the barbell rod caused by the accommodating cavity, that is, effectively improving the load-bearing performance of the barbell plate.

[0010] Preferably, the connecting rod assembly includes a driving rod and a limiting rod, the limiting rod is rotatably connected to the barbell plate body, one end of the limiting rod is movably connected to the limiting block, the side of the barbell plate body is provided with a socket that penetrates into the accommodating cavity, the driving rod is slidably inserted into the socket, the driving rod includes a first end located outside the barbell plate and a second end located inside the accommodating cavity, the second end of the driving rod is used to promote the rotation of the limiting rod, so that the user can control the rotation angle of the limiting block by pushing and pulling the limiting rod, and the operation is simple and convenient.

[0011] Preferably, a waist-shaped hole is provided at the end of the limit rod, and a pin is provided on the limit block. The pin is clamped in the inside of the waist-shaped hole to realize the movable connection between the limit rod and the limit block, thereby facilitating the processing and assembly of the connecting rod assembly.

[0012] Preferably, two transfer rods are included, and the limit blocks and limit rods are both two and symmetrically arranged on the left and right sides of the through slot, one end of the two transfer rods are respectively hinged to the other end of the two limit rods, and the other ends of the two transfer rods are hinged to the second end of the driving rod, thereby forming a symmetrical design, so that the limit blocks can more stably resist and lock the barbell bar.

[0013] Preferably, a spring is provided between the first end of the driving rod and the inner wall of the accommodating cavity, and the spring is used to push the driving rod to slide toward the inside of the accommodating cavity so that the limit block rotates toward the through groove, so that the limit block can rotate toward the through groove under the action of the spring, so as to realize automatic locking of the barbell rod in the limiting end of the through groove and prevent the barbell rod from escaping from the through groove of the barbell plate body.

[0014] Preferably, the limit block is provided with an arc-shaped clamping portion on one side of the limit end of the through slot, and the spacing between the two limit blocks on one side close to the notch end of the through slot gradually decreases in the direction toward the limit end. Therefore, due to the elastic action of the spring, the barbell bar can be directly squeezed from the outside and pass through the area between the two limit blocks until it enters the limit end of the through slot. At this time, the limit block is pushed into the through slot again under the resetting action of the spring, and the barbell bar conflicts with the clamping portion on the limit block, thereby achieving automatic locking, which makes the operation simpler and achieves a better fixing effect.

[0015] Preferably, a rotatable handle is provided at the first end of the driving rod, and a groove for placing the handle is provided on the outer side surface of the barbell plate. When the handle contacts the bottom of the groove, the limit block is in a closed state with respect to the notch end of the through groove, and when the handle contacts the outer side surface of the barbell plate, the limit block is in an open state with respect to the notch end of the through groove. This allows the user to conveniently lift and turn the handle to adjust the position of the driving rod on the one hand, and facilitates the user to pick up multiple stacked barbell plates on the other hand, thereby effectively improving practicality.

[0016] Preferably, a locking shaft is further included, and an axial through hole is provided on the barbell plate between the limit block and the side wall of the accommodating cavity, and the locking shaft is detachably inserted into the through hole. Therefore, when a plurality of barbell plates are installed on the barbell rod, the locking shaft can be inserted into the through holes of all the barbell plates on the same side of the barbell rod to achieve further locking, thereby ensuring that the closure of the notch end of the through groove by the limit block will not be opened due to external force.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 3 A quick-assembly barbell plate provided by an embodiment of the present invention includes a barbell plate body 1, a connecting rod assembly and a limit block 3. The barbell plate body 1 is provided with a radially arranged through groove 2, the through groove 2 includes a limit end 2.1 located in the middle of the barbell plate body 1 and a notch end 2.2 extending through the outer edge of the barbell plate body 1, the limit block 3 is rotatably connected to the barbell plate body 1 and is located on the outside of the through groove 2, one end of the connecting rod assembly is movably connected to the barbell plate body 1 and the other end is rotatably connected to the limit block 3, and the connecting rod assembly is used to push the limit block 3 to rotate into the through groove 2 to lock the barbell rod in the limit end 2.1.

[0024] The above scheme allows the barbell plate 1 to be directly inserted and assembled on the barbell rod along the radial direction by setting the through groove 2 on the barbell plate body 1; then the limit block 3 is pushed to rotate by the connecting rod assembly to achieve the closure of the notch end 2.2 of the through groove 2. At this time, the barbell rod is locked between the limit end 2.1 of the through groove 2 and the limit block 3, completing the installation.

[0025] In this embodiment, a accommodating chamber 1.1 is provided inside the barbell plate 1, and the stopper 3 and the connecting rod assembly are both located inside the accommodating chamber 1.1, thereby protecting the stopper 3 and the connecting rod assembly and avoiding damage caused by collision. The through groove 2 in this embodiment is located at the lower part of the barbell plate 1, and the plug hole 1.2 is located at the upper part of the barbell plate 1. However, in fact, the position of the through groove 2 or the plug hole 1.2 does not need to be limited in this design, and it can be any position of the circumference of the barbell plate 1, as long as the two do not overlap.

[0026] As an optimization of the above embodiment, the space of the accommodating chamber 1.1 located at the upper part of the barbell plate 1 is larger than the space located at the lower part of the barbell plate 1 so that the center of gravity of the barbell plate 1 is located at the lower part, thereby ensuring that after the user installs the barbell plate 1 on the barbell bar, the center of gravity of all the barbell plates 1 is located at the lower part, avoiding the offset problem caused by uneven weight, not only ensuring the exercise effect, but also facilitating the disassembly and assembly of the barbell plate on the barbell bar. In addition, the upper side wall of the limiting end 2.1 of the through groove 2 is provided with an arc-shaped convex load-bearing part 1.4, thereby compensating for the strength reduction problem of the connection part between the barbell plate 1 and the barbell bar caused by the accommodating chamber 1.1, that is, effectively improving the load-bearing performance of the barbell plate 1.

[0027] It should be noted that the connecting rod assembly and the limit block 3 can also be directly arranged on the outer end surface of the barbell plate 1. In this case, the limit block 3 can already realize the basic closing function of the notch end 2.2 of the through groove 2, which belongs to the same design concept.

[0028] The connecting rod assembly includes a driving rod 5 and a limiting rod 4. A pin is provided in the middle of the limiting rod 4. The limiting rod 4 is rotatably connected to the barbell plate body 1 through the pin. One end of the limiting rod 4 is movably connected to the limiting block 3. The side of the barbell plate body 1 is provided with a plug hole 1.2 that penetrates the accommodating chamber 1.1. The driving rod 5 is slidably plugged into the plug hole 1.2. The driving rod 5 includes a first end located outside the barbell plate and a second end located inside the accommodating chamber 1.1. The second end of the driving rod 5 is used to promote the rotation of the limiting rod 4, so that the user can control the rotation angle of the limiting block 3 by pushing and pulling the limiting rod 4, and the operation is simple and convenient.

[0029] In this embodiment, the movable connection between the limit rod 4 and the limit block 3 refers to: a waist-shaped hole 4.1 is provided at the end of the limit rod 4, and a pin is provided on the limit block 3, and the pin is clamped inside the waist-shaped hole 4.1 to realize the movable connection between the limit rod 4 and the limit block 3, thereby facilitating the processing and assembly of the connecting rod assembly. Of course, the above-mentioned movable connection can also be in other forms, such as replacing the waist-shaped hole 4.1 with a slide groove, and the pin is slidably connected in the slide groove, which can also achieve the above-mentioned rotatable and slidable movable connection effect.

[0030] As an optimization of the above embodiment, the connecting rod assembly also includes two transfer rods 6, the limit block 3 and the limit rod 4 are both two and symmetrically arranged on the left and right sides of the through slot 2, one end of the two transfer rods 6 is respectively hinged to the other end of the two limit rods 4, and the other end of the two transfer rods 6 is hinged to the second end of the driving rod 5, so that the limit block 3 can more firmly resist and lock the barbell bar. In addition, a spring 7 can be arranged between the first end of the driving rod 5 and the inner side wall of the accommodating chamber 1.1, and the spring 7 is used to push the driving rod 5 to slide in the direction of the inside of the accommodating chamber 1.1 so that the limit block 3 rotates in the direction of the through slot 2, so that the limit block 3 can be kept in a closed state with respect to the notch end 2.2 of the through slot 2 under the action of the spring 7. Of course, it can be understood that if the spring 7 is not arranged, the control and maintenance of the rotation angle of the limit block 3 can also be achieved by the damping force between the driving rod 5 and the jack 1.2.

[0031] Furthermore, an arc-shaped clamping portion 3.1 is provided on one side of the limit block facing the limit end 2.1 of the through slot 2, and the spacing between the two limit blocks 3 on one side close to the notch end 2.2 of the through slot 2 gradually decreases in the direction toward the limit end 2.1. Therefore, due to the elastic action of the spring 7, the barbell bar can be directly squeezed from the outside and pass through the area between the two limit blocks 3 until it enters the limit end 2.1 of the through slot 2. At this time, the limit block 3 is pushed into the through slot 2 again under the resetting action of the spring 7, and the barbell bar conflicts with the clamping portion 3.1 on the limit block 3, thereby achieving automatic locking, which makes the operation simpler and achieves a better fixing effect.

[0032] In addition, a handle 5.1 is provided at the first end of the driving rod 5, and a groove 1.3 for placing the handle 5.1 is provided on the outer side surface of the barbell plate 1. When the handle 5.1 contacts the bottom of the groove 1.3, the limit block 3 is in a closed state relative to the notch end 2.2 of the through groove 2, and when the handle 5.1 contacts the outer side surface of the barbell plate 1, the limit block 3 is in an open state relative to the notch end 2.2 of the through groove 2. This allows the user to easily lift and turn the handle 5.1 to adjust the position of the driving rod 5 on the one hand, and it is convenient for the user to pick up multiple stacked barbell plates 1 on the other hand, effectively improving the practicality.

[0033] like Figure 4As shown, in another embodiment, a locking shaft 8 is also included, and a through hole 1.4 is provided along the axial direction at a position between the limit block 3 and the side wall of the accommodating chamber 1.1 on the barbell plate 1, and the locking shaft 8 is detachably plugged into the through hole 1.4, so that when multiple barbell plates 1 are installed on the barbell bar, the locking shaft 8 can be plugged into the through holes 1.4 of all the barbell plates 1 on the same side of the barbell bar to achieve further locking, ensuring that the closure of the notch end of the through groove 2 by the limit block 3 will not be opened due to external force. The detachable connection between the locking shaft 8 and the through hole 1.4 can be a threaded connection or a snap-fit ​​connection, which is not limited in this design comparison.

[0034] Compared with the barbell plates installed from the side in the prior art, the barbell plate body 1 of this scheme requires a smaller installation space, and each barbell plate body 1 located on the inner side of the barbell rod can be independently disassembled and assembled, which is more convenient and practical than the traditional disassembly and assembly method of removing the barbell plates one by one from the barbell rod.

[0035] The present invention is described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
