Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, and in particular to a barbell that is easy to assemble. Background Technology

[0002] A barbell is a piece of equipment used for physical exercise. It is usually made by casting. In order to make the barbell more comfortable to hold, soft materials such as silicone or plastic are often used in the grip. Existing barbells are relatively troublesome to change weights and assemble. Therefore, a new type of barbell is needed to solve this problem. Utility Model Content

[0003] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a barbell that is easy to assemble.

[0005] To achieve the above objectives, the technical solution of this utility model is: a barbell that is easy to assemble, comprising a shell and a counterweight, wherein a placement cavity is provided inside the shell, and a placement opening communicating with the placement cavity is provided at one end of the shell, the counterweight is disposed in the placement cavity, and a sealing mechanism for sealing the placement opening is provided at the placement opening.

[0006] By adopting the above technical solution, the counterweight can be inserted into the placement cavity in the outer shell through the placement port. The placement port is blocked by the sealing mechanism to prevent the counterweight from falling out of the placement cavity. The outer shell is made of silicone or plastic to ensure the feel of the counterweight when holding it. At the same time, the method of inserting the counterweight by opening the sealing mechanism makes it more convenient to assemble or change the weight of the barbell.

[0007] Preferably, the sealing mechanism includes a cover with a stepped edge and a retaining ring at the entrance of the placement cavity, the retaining ring abutting against the stepped edge. This invention utilizes the interlocking of the stepped edge and the retaining ring to prevent the cover from easily detaching from the outer shell under axial force, thus sealing the counterweight within the placement cavity. During installation, the cover opens and engages with the placement cavity through the deformation of the outer shell and its own body.

[0008] Preferably, the outer shell has a hexagonal cross-section. This structure, with its multiple edges, enhances friction, making the barbell less likely to slip from the hand.

[0009] Preferably, the longitudinal cross-section of the outer shell is hyperbolic on both sides. This invention, through its hyperbolic cross-sectional structure, causes the middle of the outer shell to be concave, forming a structure that is wide at both ends and narrow in the middle, thereby further facilitating the release of the barbell.

[0010] Preferably, each edge of the outer shell is rounded. This invention utilizes rounded corners to enhance the grip feel of the barbell, making it more comfortable.

[0011] Preferably, the counterweight is cylindrical. This invention utilizes the cylindrical shape to make the counterweight easy to insert into the placement cavity, thus making assembly more convenient.

[0012] Preferably, the placement cavity is cylindrical, and the inner diameter of the placement cavity is equal to the outer diameter of the counterweight. This invention utilizes the matching shape of the placement cavity and the counterweight to allow the outer shell to cover the counterweight, enabling the counterweight to resist slippage due to the friction between the outer shell and the counterweight.

[0013] Preferably, there are two placement openings, one at each end of the outer casing. This invention allows counterweights to be placed at both ends of the outer casing.

[0014] Preferably, the lower end of the cap is tapered, and the placement opening matches the shape of the cap. This invention utilizes the tapered lower end of the cap to facilitate insertion into the placement opening.

[0015] Preferably, the cover is provided with an insertion hole, and the counterweight is inserted into the insertion hole. This invention, by inserting the counterweight into the insertion hole, utilizes friction to prevent the counterweight from rotating or sliding.

[0016] In summary, the beneficial effects of this utility model are:

[0017] 1. The weight block can be inserted through the placement port in the placement cavity of the outer shell. The placement port is blocked by the sealing mechanism to prevent the weight block from falling out of the placement cavity. The outer shell is made of silicone or plastic to ensure the feel of the weight block when holding it. At the same time, the method of inserting the weight block by opening the sealing mechanism makes it more convenient to assemble or change the weight of the barbell.

[0018] 2. The outer shell's shape and structure enhance its friction, making the barbell less likely to slip out of your hands.

[0032] like Figure 1-2 As shown, a barbell that is easy to assemble includes a shell 1 and a counterweight 2. The shell 1 has a placement cavity inside, and one end of the shell 1 has a placement opening that communicates with the placement cavity. The counterweight 2 is placed inside the placement cavity, and a sealing mechanism for sealing the placement opening is provided at the placement opening.

[0033] By adopting the above technical solution, the counterweight 2 can be inserted into the placement cavity in the outer shell 1 through the placement port. The placement port is blocked by the sealing mechanism so that the counterweight 2 will not fall out of the placement cavity. The outer shell 1 is made of silicone or plastic to ensure the feel of the counterweight 2 when holding it. At the same time, the method of inserting the counterweight 2 by opening the sealing mechanism makes it more convenient to assemble or change the weight of the barbell.

[0034] The sealing mechanism includes a cover 3, the edge of which is stepped, and a retaining ring 4 is provided at the entrance of the placement cavity, the retaining ring 4 abutting against the step. By utilizing the interlocking of the step and the retaining ring 4, the cover 3 is not easily dislodged from the outer shell 1 when subjected to axial force, thus sealing the counterweight 2 inside the placement cavity. During installation, the cover 3 is inserted into the placement cavity by the deformation of the outer shell 1 and itself.

[0035] The outer shell 1 has a hexagonal cross-section. This structure gives the outer shell 1 multiple edges, which enhances friction and makes the barbell less likely to slip out of your hands.

[0036] The longitudinal cross-section of the outer shell 1 is hyperbolic on both sides. The hyperbolic cross-sectional structure causes the middle of the outer shell 1 to be concave, forming a structure that is large at both ends and narrow in the middle, thereby further supporting the release of the barbell.

[0037] Each edge of the outer shell 1 is rounded. The rounded corners enhance the grip feel of the barbell, making it more comfortable.

[0038] The counterweight 2 is cylindrical. The cylindrical shape makes it easy to insert the counterweight 2 into the placement cavity, making assembly more convenient.

[0039] The placement cavity is cylindrical, and its inner diameter is equal to the outer diameter of the counterweight 2. By matching the shapes of the placement cavity and the counterweight 2, the outer shell 1 can cover the counterweight 2, and the counterweight 2 can utilize the friction between the outer shell 1 and the counterweight 2 to prevent it from sliding.

[0040] There are two placement ports, one at each end of the outer casing 1. This allows the counterweight 2 to be placed at both ends of the outer casing 1.

[0041] The lower end of the cap 3 is conical, and the placement opening matches the shape of the cap 3. The conical lower end of the cap 3 makes it easy to insert the cap 3 into the placement opening.

[0042] The cover 3 has a socket 5, and the counterweight 2 is inserted into the socket 5. By inserting the counterweight 2 into the socket 5, friction can be used to prevent the counterweight 2 from rotating or sliding.

[0043] It should be noted that many specific details have been set forth in the above description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
