As used herein, the terms "first", "second", and "third" etc. are used interchangeably to distinguish one component from another, and are not intended to indicate the position or importance of individual components.

[0039] In order to solve the problems of the complicated structure of the conventional adjustable dumbbells, the inconvenience of weight increase / decrease operation, and the easy shaking of the dumbbell plate unit, the present embodiment provides a new type of adjustable dumbbell, such as Figure 1 As shown, the dumbbell is mainly composed of three parts: a handle 1 and two weights 2. The two weights 2 are respectively arranged at two ends of the handle 1 and are fixedly connected to the handle 1. The two weights 2 have the same structure and are adjustable in weight.

[0040] See also Figure 2Each weight 2 is composed of three parts: a dumbbell plate group 21, a positioning frame 22 and a positioning pin 23. Among them, the dumbbell plate group 21 is the weight core of the weight 2, and is composed of a plurality of dumbbell plate units 211 that are sequentially clamped. Each dumbbell plate unit 211 is provided with a positioning hole 2113 that runs through both sides. The positioning frame 22 is sleeved on the outside of the dumbbell plate group 21, and a plurality of mounting holes 2231 corresponding to the dumbbell plate units 211 in the dumbbell plate group 21 are arranged at intervals on the above-mentioned positioning frame 22.

[0041] The positioning pin 23 is inserted into any one or any group of mounting holes 2231 on the positioning frame 22 and the positioning hole 2113 on the corresponding dumbbell plate unit 211, and the corresponding dumbbell plate unit 211 and all the dumbbell plate units 211 located inside the corresponding dumbbell plate unit 211 are locked in the positioning frame 22, or the corresponding dumbbell plate unit 211 and all the dumbbell plate units 211 located outside the corresponding dumbbell plate unit 211 are locked in the positioning frame 22. At this time, when holding the handle of the dumbbell and lifting it up, the dumbbell plate unit 211 locked in the positioning frame 22 by the positioning pin 23 can be taken together, and the unlocked dumbbell plate unit 211 is placed in place. Therefore, by inserting the positioning pin 23 into different mounting holes 2231 on the positioning frame 22, the number of dumbbell plate units 211 to be taken can be adjusted, and the weight adjustment can be completed, and the operation is simple. Figure 3 As shown, when the positioning pin 23 is inserted into the first mounting hole 2231 on the inner side of the positioning frame 22, only one dumbbell piece unit 211 on the inner side of the dumbbell piece set 21 can be taken to take the dumbbell. Figure 4 As shown, if the positioning pin 23 is inserted into the second mounting hole 2231 inside the positioning frame 22 , the dumbbell can be taken by taking the two inner dumbbell plate units 211 of the dumbbell plate set 21 .

[0042] The novel adjustable dumbbell provided by the above-mentioned implementation scheme has a brand-new structural design for the structure of the weight 2. A positioning hole 2113 is provided on each dumbbell plate unit 211, which cooperates with the mounting hole 2231 on the positioning frame 22. By plugging and pulling out the positioning pin 23, different numbers of dumbbell plate units 211 can be locked in the positioning frame 22, thereby adjusting the number of locked dumbbell plate units 211, that is, increasing or decreasing the weight of the weight 2. This simplifies the structure and facilitates operation. When the dumbbell is lifted, the dumbbell plate units 211 locked in the positioning frame 22 are restricted by the positioning frame 22, which can effectively solve the problem of shaking during lifting and improve the safety factor.

[0043] See also Figure 5The present embodiment provides a specific dumbbell unit structure, wherein one side of the dumbbell unit 211 is provided with an inwardly recessed locking groove 2111, the locking groove 2111 passes through the top of the dumbbell unit 211, and the other side of the dumbbell unit 211 is correspondingly provided with an outwardly protruding locking block 2112, the locking block 2112 cooperates with the locking groove 2111 in the adjacent dumbbell unit 211 to slide and engage.

[0044] Through the cooperation between the locking groove 2111 and the locking block 2112 between the above-mentioned dumbbell plate units, when the positioning pin 23 is inserted into the positioning hole 2113 of any dumbbell plate unit 211, the dumbbell plate unit 211 of the locking groove 2111 of the dumbbell plate unit 211 is locked together through the cooperation between the above-mentioned locking block and the locking groove, and the locking block of the dumbbell plate unit 211 slides out of the locking groove of the adjacent dumbbell plate unit 211, and the two are automatically unlocked.

[0045] The shape of the dumbbell plate unit 211 can be freely set according to preference, such as triangular, trapezoidal, etc. Figure 5 Taking the common square shape as an example, the dumbbell unit 211 can be made of traditional high-density metal, or it can be a structure with an injection molded shell and built-in high-density filler. The structural design of the injection molded shell and built-in high-density filler can control the metal material within 15%, and 85% of the material is replaced by natural materials and degradable materials, which can not only significantly reduce carbon emissions, but also reduce costs and product prices.

[0046] In order to make the dumbbell unit 211 and the positioning frame 22 fit better, as an improvement of the technical solution, see Figure 1 , a locking groove 2111 recessed inwardly is provided on one side of the dumbbell piece unit 211 located at the outer end of the dumbbell piece set 21, and the other side is a plane. At this time, the locating pin 23 is inserted into the locating hole 2113 of the dumbbell piece unit 211, and the dumbbell piece unit 211 and all the dumbbell piece units 211 on the inner side can be locked; if a locking groove 2111 recessed inwardly is provided on one side of the dumbbell piece unit 211 located at the inner end of the dumbbell piece set 21, and the other side is a plane, at this time, the locating pin 23 is inserted into the locating hole 2113 of the dumbbell piece unit 211, and the dumbbell piece unit 211 and all the dumbbell piece units 211 on the outer side can be locked.

[0047] In order to improve the firmness of the clamping between the dumbbell plate units 211, as an improvement of the technical solution, the end surface of the locking groove 2111 and the end surface of the locking block 2112 are both dovetail-shaped.

[0048] See also Figure 2The positioning frame 22 is mainly composed of a first side plate 221, a second side plate 222 and a connecting rod 223, wherein the first side plate 221 and the second side plate 222 are arranged in parallel at intervals, and the first side plate 221 and the second side plate 222 are both fixedly connected to the connecting rod 223, and mounting holes 2231 are arranged at intervals on the connecting rod 223, and the mounting holes 2231 are all located between the first side plate 221 and the second side plate 222. Among them, the connecting rod 223 of the positioning frames 22 at both ends of the handle can be either two independent connecting rods or one connecting rod. When there are two independent connecting rods, the two positioning frames 22 are connected by the handle 1, and the two ends of the handle are fixedly welded to the adjacent side plates of the two positioning frames 22; when there is one connecting rod, the two positioning frames 22 are connected by the connecting rod, and the handle 1 is a hollow sleeve, the handle is located between the two positioning frames 22, and is fixedly sleeved on the outside of the connecting rod 223. The specific structure is as follows: Figure 6 As shown, when the two positioning frames 22 share a connecting rod, mounting holes 2231 are spaced apart at both ends of the connecting rod 223 .

[0049] In order to facilitate the installation of each dumbbell unit, as an improvement of the technical solution, see Figure 5 A mounting hole 2114 is longitudinally provided in the center of each dumbbell unit 211 and passes through both sides, and the upper end of the mounting hole 2114 passes through the upper end of the dumbbell unit 211. The above-mentioned mounting hole 2114 is mainly used for the connection rod 223 in the positioning frame 22 to pass through.

[0050] See also Figure 7 The positioning pin 23 is mainly composed of a latch rod 231, a latch cap 232 and a magnet 233, wherein the latch rod 231 is U-shaped, with one end open and the other end closed, and the latch cap 232 is composed of an upper and lower part, which are snap-fitted onto the closed end of the latch rod 231, and a mounting groove 2321 is arranged on the inner side of the latch cap 232, and the magnet 233 is mounted in the mounting groove 2321 of the latch cap 232. When the positioning pin 23 is inserted into the mounting hole 2231 in the positioning frame 22 and the positioning hole of the dumbbell unit, the magnetic attraction of the magnet can generate a force to prompt the positioning pin 23 to be inserted inward, which is convenient for operation. At the same time, after being installed in place, the magnet is tightly magnetically attracted to the dumbbell unit to prevent accidental falling, thereby further improving safety.

[0051] The latch rod 231 can be Figure 7 The U-shape can also be a traditional straight shape. The main purpose of using the U-shape is to improve stability. The U-shaped latch rod is equivalent to using two interval points to limit the dumbbell unit to avoid shaking.

[0052] In conjunction with the use of the U-shaped latch rod 231, two positioning holes 2113 are spaced apart on each dumbbell unit 211. The positioning holes can be set inside the dumbbell unit 211 and pass through both sides. However, for the convenience of processing, it is preferred to Figure 5 As shown, arc-shaped grooves recessed inwards are provided on both sides of the dumbbell plate unit 211 as two spaced apart positioning holes.

[0053] See also Figure 8 The adjustable dumbbell also includes: a base 3, see Figure 1 The base 3 is used for bearing the handle 1 and the weights 2 at both ends. Both ends of the base 3 are bearing areas 31. The upper surface of each bearing area is provided with a limited boss 311 at intervals. The limited boss 3113 corresponds to the dumbbell unit 211 in the dumbbell set 21. Figure 5 The bottom surface of each dumbbell unit 211 is provided with a limiting groove 2115 that cooperates with the limiting boss 311. When the dumbbell set 21 is placed on the base 3, the limiting groove 2115 on the bottom surface of each dumbbell unit 211 cooperates with the corresponding limiting boss 311 to limit the position of each dumbbell unit 211.

[0054] Preferably, a pin placement slot 32 is provided on the base 3 for placing the positioning pin 23 .

[0055] In order to further improve safety, anti-slip patterns are provided on the surface of the handle 1 of the dumbbell.

[0056] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
