Description

Technical Field

[0001] The utility model relates to the field of sports equipment, in particular to a bell piece. Background Art

[0002] At present, most common strength training equipment, such as barbells, dumbbells and kettlebells, are equipped with detachable weight plates. By increasing or decreasing the number of weight plates and selecting weight plates of different weights, the effect of flexible selection of training weights can be achieved. Therefore, the importance of weight plates as the weight unit in strength training equipment can be seen.

[0003] However, whether it is a detachable or non-detachable bell plate, there is a risk of accidentally falling to the ground; in particular, the detachable bell plate may fall off the connecting rod and fall to the ground, and there is even a situation where it falls to the ground and hits the user's instep, causing injury.

[0004] Currently, in order to reduce the damage caused by falling bell discs and to reduce the noise caused by falling bell discs, bell discs are often designed as described in the patent document of Chinese Patent Publication No. CN208599062U. That is, the bell disc body is a solid discus or a hollow shell filled with iron sand, and the outer ring of the bell disc is covered with rubber. When the bell disc falls and collides with the ground, the rubber sleeve covering the outer ring of the bell disc will directly contact the impacted object and provide a cushioning effect through its own deformation.

[0005] However, when the size of the bell plate is fixed, if the weight of the bell plate is to be increased, the volume of the discus or the hollow shell needs to be increased, and the rubber sleeve covering the outer ring of the bell plate needs to be thinner accordingly. A rubber sleeve that is too thin cannot effectively provide a cushioning effect; and if an effective cushioning effect is to be achieved, the rubber sleeve needs to have a certain thickness. A rubber sleeve that is too thick is light in weight and occupies the overall volume, which will limit the weight of the bell plate and is not conducive to setting a higher weight for a single bell plate. Utility Model Content

[0006] The purpose of the utility model is to provide a technical solution for a bell piece to address the deficiencies in the prior art, which can achieve an effective buffering effect under the premise of a certain size of the bell piece and avoid the weight of the bell piece being restricted to the greatest extent.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A bell plate comprises a plate body and a buffer structure coated on the outer ring of the plate body, wherein the buffer structure can deform and provide a buffering effect when the bell plate collides; the buffer structure is provided with a granular filler, which is coated on the inner side of the buffer structure and partially or completely surrounds the outer ring of the plate body; the granular filler can increase the weight of the bell plate and can flow and provide a buffering effect when the bell plate collides.

[0009] By adopting the above technical solution, the buffer structure coated on the outer ring of the disc body can achieve a buffering effect by deformation when the bell piece falls to the ground and collides, and the granular filler located on the inner side of the buffer structure and partially or completely surrounding the outer ring of the disc body can achieve overall deformation by flowing when the bell piece collides, thereby providing a further buffering effect; the weight of the granular filler is much heavier than the same volume of rubber, and it can be used to increase the weight of the bell piece. Since it is coated on the inner side of the buffer structure, the granular filler replaces the pure rubber sleeve coating design in the prior art, thus achieving an effective buffering effect and at the same time avoiding the weight restriction of the bell piece to the greatest extent; in addition, due to the influence of the elastic modulus of the rubber itself, the bell piece with a pure rubber sleeve coating design will still produce a loud noise when it falls to the ground, while the flow and the gap characteristics of the granular filler can effectively reduce the noise when the bell piece falls to the ground.

[0010] Furthermore, a connecting ring is formed on the inner ring of the buffer structure, and the connecting ring is cooperatively connected with the disc body, and the connecting ring is used to achieve a fixed connection between the buffer structure and the disc body.

[0011] Furthermore, clamping edges are formed on both sides of the outer ring of the disk body, and a clamping piece is provided between the two clamping edges; the connecting ring is provided between the clamping piece and the clamping edges and is clamped and fixed by the two.

[0012] By adopting the above technical solution, the clamping edge and the clamping member clamp the connecting ring of the inner ring of the buffer structure, which can fix the buffer structure and prevent it from detaching from the disc body; at the same time, the clamping member plays a supporting role inside the buffer structure, which makes the buffer structure more axially stable and prevents the buffer structure from axially shaking due to the flowable granular filler arranged on its inner side, thereby ensuring the stability of the center of gravity of the bell plate when in use.

[0013] Furthermore, the connecting ring is formed with a clamping ring, which is located between the clamping piece and the clamping edge; the clamping piece and / or the clamping edge are formed with a groove corresponding to the clamping ring, and the clamping ring cooperates with the groove to prevent the connecting ring from falling out from between the clamping piece and the clamping edge.

[0014] Furthermore, the connecting ring is provided with a plurality of locking holes, which are located between the clamping piece and the clamping edge. Locking columns corresponding to the locking holes are provided between the clamping piece and the clamping edge. The locking columns are fitted through the locking holes to prevent the connecting ring from falling out from between the clamping piece and the clamping edge.

[0015] Furthermore, a first cavity is formed between the buffer structure and the disk body, and a second cavity is formed in the disk body; the clamping member is located between the first cavity and the second cavity, and a plurality of through holes are opened on the surface of the clamping member for allowing the particle filler to pass through.

[0016] By adopting the above technical solution, when pouring granular fillers into the bell plate, it is only necessary to pour them into the first chamber. The granular fillers poured into the first chamber will flow into the second chamber through the through hole. In this way, only one pouring hole is required to complete the filling of granular fillers in both the first chamber and the second chamber.

[0017] Furthermore, a plurality of baffle structures are provided in the first chamber, the baffle structures are connected to the surface of the clamping member, and the baffle structures divide the first chamber into a plurality of partitions, and the particle filler is filled in each partition.

[0018] By adopting the above technical solution, the baffle structure divides the first chamber into multiple partitions, so that the granular filler located in the first chamber is divided into a corresponding number of granular filler units with a mass lighter than the total mass by the multiple partitions. When the bell plates collide, the instantaneous flow of the granular filler will impact the inner wall of the buffer structure, and the instantaneous impact force generated by the multiple granular filler units with a corresponding number and a lighter mass when they flow individually will be smaller than the impact force generated by the instantaneous flow in the total mass state, thereby achieving the effect of protecting the buffer structure and prolonging its service life; at the same time, the baffle structure can improve the structural stability of the bell plates to a certain extent.

[0019] Furthermore, the clamping member and the clamping edge are integrally constructed, and there is no gap at the connection between the two.

[0020] By adopting the above technical solution, the one-piece structure of the clamping piece and the clamping edge can ensure the clamping reliability, and the absence of gaps can avoid the possibility of the particle filler leaking from the joint between the two.

[0021] Furthermore, the buffer structure is provided with a positioning assembly, which acts between the buffer structure and the disc body, and is used to achieve circumferential positioning of the buffer structure relative to the disc body.

[0022] Furthermore, an assembly hole is axially opened through the disc body, and the assembly hole is polygonal.

[0023] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0024] 1. The utility model not only produces a good cushioning effect, but also because the granular filler can increase the weight of the bell piece at the same time, it avoids the problem of the weight of the bell piece being limited in order to achieve an effective cushioning effect;

[0025] 2. The utility model can effectively reduce the sound of the bell pieces falling to the ground by setting granular fillers

[0026] 3. The clamping piece of the utility model cooperates with the clamping edge to clamp and fix the connecting ring. At the same time, the clamping piece also supports the buffer structure, making the buffer structure more stable in the axial direction and ensuring the center of gravity of the bell plate is stable when in use;

[0027] 4. The utility model provides a plurality of baffle structures, which can not only reduce the instantaneous impact force of the flow of granular fillers when a collision occurs to protect the buffer structure, but also improve the structural stability of the bell piece.

[0047] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0048] In order to help those skilled in the art better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts should fall within the scope of protection of the present invention.

[0049] It should be noted that the terms "first," "second," and so on in the specification and claims of this utility model and the aforementioned drawings are used to distinguish similar items and are not necessarily used to describe a specific order or precedence. In addition, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions.

[0050] Example 1

[0051] A bell plate used for strength training equipment such as dumbbells, barbells and kettlebells;

[0052] The bell plate includes a plate body 1, and a mounting hole 13 is opened through the center of the plate body 1. Figure 1 As shown;

[0053] The assembly hole 13 is used for mounting with the connecting rod of the strength training device;

[0054] Through the cooperation of the assembly hole 13 and the connecting rod, the bell plate and the strength training device can be detachably connected, and the user can adjust the weight by adding, removing and replacing bell plates of different weights as needed.

[0055] In this embodiment, the assembly hole 13 is a quadrilateral. Figure 1 、 Figure 8 As shown;

[0056] The non-circular design of the assembly hole 13 can provide radial positioning for the connecting rod inserted therein;

[0057] In this embodiment, limiting flanges 131 are formed on both sides of the assembly hole 13. The limiting flanges 131 are used to cooperate with the limiting components matched on the connecting rod to achieve axial limitation of the bell piece and the connecting rod.

[0058] The bell piece is provided with a buffer structure 2, which is covered on the outer ring of the disc body 1. Figure 1 、 Figure 2 As shown;

[0059] When the bell plate falls to the ground and collides, the buffer structure 2 can deform to achieve a buffering effect;

[0060] In this embodiment, the buffer structure 2 is a rubber ring.

[0061] The buffer structure 2 is provided with a granular filler, which is coated on the inner side of the buffer structure 2 and partially surrounds the outer ring of the disk body 1;

[0062] The granular filler located inside the buffer structure 2 and surrounding the outer ring of the disc body 1 will flow along with the deformation of the buffer structure 2 when the bell discs collide. The granular filler will achieve overall deformation through flow, thereby achieving a further buffering effect.

[0063] A granular filler is provided between the buffer structure 2 and the outer ring of the disk body 1 for buffering, which not only achieves the same or even better buffering effect, but also, under the premise of a certain size of the bell piece, the weight of the granular filler is much heavier than that of rubber, and it can be used to increase the weight of the bell piece. That is, the granular filler coated on the inner side of the buffer structure 2 will replace the design of the pure rubber sleeve covering the bell piece in the prior art, which can achieve the buffering effect and also avoid the weight of the bell piece being restricted to the greatest extent; in addition, due to the elastic modulus of the rubber material, the design of the pure rubber sleeve covering the bell piece will still make a loud noise when the bell piece falls to the ground. The gaps between the granular fillers have a good sound-absorbing effect, and the granular fillers absorb energy through flow, and its characteristics will more effectively reduce the sound when the bell piece falls to the ground.

[0064] The inner ring of the buffer structure 2 is formed with a connecting ring 22, such as Figure 3、 Figure 14 As shown;

[0065] The connecting ring 22 is integrally formed on the inner ring of the buffer structure 2 and is used to connect and fix with the disk body 1;

[0066] The disk body 1 is composed of a left shell 11 and a right shell 12. The left shell 11 and the right shell 12 extend toward the outer ring to form a clamping edge 15 located on both sides of the outer ring of the disk body 1. Figure 2 、 Figure 8 As shown;

[0067] A clamping member 3 is provided between the two clamping edges 15, such as Figure 2 、 Figure 12 As shown;

[0068] The connecting ring 22 is clamped between the clamping member 3 and the clamping edge 15, as shown in FIG. Figure 2 As shown;

[0069] The clamping member 3 cooperates with the clamping edge 15 to clamp and fix the connecting ring 22, thereby realizing the connection and fixation of the buffer structure 2 and the disc body 1. It can not only prevent the buffer structure 2 from detaching from the disc body 1, but also the clamping member 3 plays a supporting effect on the inner side of the buffer structure 2, which can make the buffer structure 2 more axially stable, thereby avoiding the axial shaking of the buffer structure 2 caused by the flow of the granular filler arranged on its inner side, and ensuring the stability of the center of gravity of the bell plate when in use.

[0070] In summary, in this embodiment, the bell plate includes a disc body 1 and a buffer structure 2 wrapped around the outer ring of the disc body 1. The inner ring of the buffer structure 2 is formed with a connecting ring 22. The outer ring of the disc body 1 is formed with a clamping edge 15. The clamping member 3 is arranged in the disc body 1 and between the clamping edges 15 on both sides. The connecting ring 22 is arranged between the clamping edge 15 and the clamping member 3. The clamping member 3 cooperates with the clamping edge 15 to clamp the connecting ring 22. Figure 15 As shown; the disc body 1 is the weight unit of the bell piece, and the buffer structure 2 coated on the outer ring of the disc body 1 is used for buffering when the bell piece collides. The clamping member 3 and the clamping edge 15 fix the buffer structure 2 by clamping the connecting ring 22. The inner side of the buffer structure 2 has a space for filling granular fillers.

[0071] In this embodiment, the clamping member 3 is sunken between the two clamping edges 15, and there is a recessed space between the two side walls of the clamping member 3, such as Figure 2 、 Figure 5 As shown;

[0072] In this embodiment, the space inside the buffer structure 2 surrounding the outer ring of the disk body 1 and the recessed space between the two side walls of the clamping member 3 together form a first chamber 21. Figure 2 、 Figure 14 As shown;

[0073] In this embodiment, the particle filler poured into the first chamber 21 partially surrounds the outer ring of the disc body 1 .

[0074] In this embodiment, the granular filler is preferably but not limited to iron sand. If the weight of the bell piece needs to be lighter, quartz sand or yellow sand can also be used.

[0075] The granular filler poured into the first chamber 21 not only provides a further cushioning effect, but also increases the overall weight of the weight plate.

[0076] The connecting ring 22 is formed with a collar 23, such as Figure 3 、 Figure 4 As shown;

[0077] The clamping ring 23 is located between the clamping member 3 and the clamping edge 15. Figure 2 As shown;

[0078] A clamping groove 24 corresponding to the clamping ring 23 is formed between the clamping member 3 and the clamping edge 15. Figure 2 、 13 As shown;

[0079] In this embodiment, the clamping slot 24 is composed of a first clamping slot structure formed on the inner side wall of the clamping edge 15 and a second clamping slot structure formed on the outer side wall of the clamping member 3. Figure 13 As shown;

[0080] The connecting ring 22 is tightened between the clamping member 3 and the clamping edge 15 , and the coupling and limiting function of the clamping ring 23 and the clamping groove 24 can prevent the connecting ring 22 from falling out from between the clamping member 3 and the clamping edge 15 .

[0081] The connecting ring 22 is provided with a plurality of locking holes 25, such as Figure 3 、 Figure 14 As shown;

[0082] The locking hole 25 is located between the clamping member 3 and the clamping edge 15 , and the locking post 17 can fit through the locking hole 25 ;

[0083] In this embodiment, the locking column 17 is formed on the inner side wall of the clamping edge 15. Figure 8 、 Figure 9 As shown;

[0084] One end of the locking column 17 is in close contact with the outer wall of the clamping member 3 and extends across the clamping edge 15 and the clamping member 3. Figure 12 As shown;

[0085] In this embodiment, the locking post 17 is integrally constructed with the clamping member 3 and the clamping edge 15;

[0086] The locking post 17 fits through the locking hole 25 , which can further prevent the connecting ring 22 from falling out from between the clamping member 3 and the clamping edge 15 .

[0087] The clamping member 3 is located on the inner side of the connecting ring 22, and the clamping edge 15 is located on the outer side of the connecting ring 22;

[0088] In this embodiment, the inner side wall of the connecting ring 22 is formed with a convex strip structure 27, such as Figure 3 As shown;

[0089] The outer wall of the clamping member 3 is formed with a recessed structure 33, such as Figure 5 As shown;

[0090] The convex strip structure 27 cooperates with the concave structure 33 to limit the position, so as to further prevent the connecting ring 22 from falling out from between the clamping member 3 and the clamping edge 15 .

[0091] The buffer structure 2 is provided with a positioning component, which acts between the buffer structure 2 and the disc body 1 and can realize the circumferential positioning of the buffer structure 2 relative to the disc body 1;

[0092] The buffer structure 2 is formed with a positioning notch 29 for cooperating with an external positioning member, such as Figure 1 、 Figure 3 As shown;

[0093] The positioning notch 29 cooperates with the external positioning member to lock the bell in its position and prevent it from rotating in the circumferential direction.

[0094] In order to ensure that the buffer structure 2 can be accurately positioned when assembled with the disk body 1 and the clamping member 3, in this embodiment, a positioning hole 26 is opened on the connecting ring 22, and a positioning column 35 corresponding to the positioning hole 26 is formed on the outer wall of the clamping member 3. Figure 3 、 Figure 5 As shown;

[0095] The positioning post 35 is inserted into the positioning hole 26. Figure 14 As shown; the circumferential positioning of the clamping member 3 and the buffer structure 2 is realized;

[0096] The positioning hole 26 is a strip-shaped hole, such as Figure 3 As shown;

[0097] In this embodiment, the inner ring of the clamping member 3 is formed with a positioning card 34, such as Figure 5 、 Figure 14 As shown;

[0098] A positioning slot 16 corresponding to the positioning card 34 is provided in the disk body 1. Figure 8 、 Figure 11 As shown;

[0099] The positioning card 34 is engaged with the positioning slot 16 to achieve circumferential positioning of the clamping member 3 and the disk body 1;

[0100] The clamping member 3 is circumferentially positioned relative to the disc body 1, and the buffer structure 2 is circumferentially positioned relative to the clamping member 3, so that the buffer structure 2, the disc body 1, and the clamping member 3 are accurately positioned when assembled;

[0101] In this embodiment, the positioning post 35 passes through the positioning hole 26, and one end thereof is in close contact with the clamping edge 15;

[0102] In this embodiment, the positioning column 35 is integrally constructed between the clamping part 3 and the clamping edge 15 .

[0103] In this embodiment, a second chamber 14 is formed in the disc body 1. Figure 2 、 Figure 9 as well as Figure 10 As shown;

[0104] The second chamber 14 is filled with granular fillers to increase the overall weight of the weight plate;

[0105] The clamping member 3 is located between the first chamber 21 and the second chamber 14, forming a separation between the first chamber 21 and the second chamber 14. Figure 2 、 Figure 12 As shown;

[0106] The surface of the buffer structure 2 is provided with a pouring hole 4, such as Figure 14 As shown;

[0107] The filling hole 4 is equipped with a sealing cover 28. Figure 1 、 Figure 3 As shown;

[0108] The filling hole 4 is used to fill the first chamber 21 with granular fillers;

[0109] After the granular fillings in the first chamber 21 and the second chamber 14 are poured, the pouring hole 4 can be sealed by the sealing cover 28;

[0110] In this embodiment, the sealing cover 28 and the pouring hole 4 are sealed and fixed by glue;

[0111] The surface of the clamping member 3 is provided with a plurality of through holes 31, such as Figure 5 、 Figure 12 as well as Figure 14 As shown;

[0112] The through hole 31 communicates with the first chamber 21 and the second chamber 14 for allowing the granular filler to pass therethrough;

[0113] When the bell plate is filled with granular filler, it is only necessary to pour the granular filler into the first chamber 21 through the pouring hole 4, and the granular filler will enter the second chamber 14 through the through hole 31. In this way, the bell plate only needs to open one pouring hole 4 to realize the pouring of the entire granular filler.

[0114] In this embodiment, a plurality of baffle structures 32 are provided in the first chamber 21. The baffle structures 32 are formed on the outer surface of the clamping member 3. Figure 5 、 Figure 12 As shown;

[0115] The baffle structure 32 can serve as a reinforcing rib to increase the structural stability of the clamping member 3, thereby improving the overall structural strength of the bell piece;

[0116] The first chamber 21 is divided into a plurality of partitions by a plurality of baffle structures 32. Figure 12 As shown, the particle filling in the first chamber 21 is separated into various partitions by the baffle structure 32;

[0117] The particle filling in the first chamber 21 is divided into various partitions, and the mass of the particle filling divided into each partition is less than the total mass of the particle filling in the first chamber 21;

[0118] When the bell plates collide, the granular filler flows with the deformation of the buffer structure 2, and an impact force is generated in the buffer structure 2 at the moment of flow. Since the granular filler is separated into various partitions, the mass of the granular filler in the partition is much lighter than the total mass of the granular filler in the first chamber 21, and the corresponding impact force will also be reduced due to dispersion. In this way, the impact force on the buffer structure 2 at the moment of flow of the granular filler can be reduced, thereby protecting the buffer structure 2 and increasing its service life.

[0119] The connecting ring 22 of the inner ring of the buffer structure 2 is clamped between the clamping edge 15 and the clamping member 3;

[0120] In this embodiment, the clamping edge 15 and the clamping member 3 are integrally constructed, and there is no gap at the connection between the two;

[0121] The integrated structure ensures the clamping reliability of the clamping edge 15 and the clamping member 3, and further ensures the stable connection of the connecting ring 22 between the two;

[0122] The seamless connection between the clamping edge 15 and the clamping member 3 ensures that the granular filler will not leak out from the connection between the disk body 1 and the buffer structure 2 after being poured into the first chamber 21 and the second chamber 14 .

[0123] Example 2

[0124] This embodiment is different from the first embodiment in that the surface of the clamping member 3 is flush with the outer surface of the disk body 1, so that the first cavity 21 completely surrounds the disk body 1;

[0125] That is, in this embodiment, the granular filler poured into the first chamber 21 completely surrounds the outer ring of the disc body 1 .

[0126] In this embodiment, the clamping groove 24 is formed on the inner side wall of the clamping edge 15 and cooperates with the clamping ring 23 to limit the position.

[0127] In this embodiment, the locking post 17 is formed on the inner side wall of the clamping edge 15;

[0128] The outer wall of the clamping member 3 is provided with a second locking hole 36 corresponding to the locking column 17. Figure 5 As shown;

[0129] The locking post 17 fits through the locking hole 25 and one end is inserted into the second locking hole 36 , thereby preventing the connecting ring 22 from falling out from between the clamping member 3 and the clamping edge 15 .

[0130] In this embodiment, the inner wall of the connecting ring 22 is formed with a recessed structure, and the outer wall of the clamping member 3 is formed with a convex strip structure that cooperates with the recessed structure. The convex strip structure cooperates with the recessed structure to limit the position, which is used to further prevent the connecting ring 22 from falling out from between the clamping member 3 and the clamping edge 15.

[0131] In this embodiment, a positioning hole 26 is formed on the connecting ring 22, and a positioning post adapted to the positioning hole 26 is formed on the inner side wall of the clamping edge 15. The positioning post passes through the positioning hole 26 to achieve matching and limiting.

[0132] In this embodiment, the positioning hole is preferably, but not limited to, a rectangular hole. This is only a preferred embodiment. The positioning hole may also be a triangle, a pentagon, or other shapes. It is different from the locking hole 25 and is used for accurate positioning of the buffer structure 2 and the disk body 1.

[0133] One end of the positioning column is in close contact with the outer wall of the clamping member 3 .

[0134] In this embodiment, the sealing cover 28 and the pouring hole 4 are sealed and fixedly connected by hot melting.

[0135] In this embodiment, the buffer structure 2 is an annular sleeve made of PU material.

[0136] Example 3

[0137] This embodiment is different from the first embodiment in that, in this embodiment, the clamping groove 24 is formed on the outer wall of the clamping member 3 and cooperates with the clamping ring 23 to limit the position.

[0138] In this embodiment, positioning holes are formed on the side walls of the clamping edge 15 and the clamping member 3 relative to the connecting ring 22, and positioning columns are formed on both sides of the connecting ring 22 corresponding to the positioning holes. The positioning columns and the positioning holes cooperate to limit the connection ring 22 from falling out from between the clamping member 3 and the clamping edge 15.

[0139] In this embodiment, the buffer structure 2 is a silicone sleeve.
