Description

Technical Field

[0001] This utility model relates to the field of dumbbell equipment technology, specifically a simple and quick-assembly adjustable dumbbell. Background Technology

[0002] In the existing technology, dumbbells are divided into two types. One type has a dumbbell bar and dumbbell plates that are molded as a single piece, and its weight is not adjustable. As users' strength requirements gradually increase, they need to purchase multiple sets of dumbbells of different weights, which is costly and takes up a lot of space. The other type has a dumbbell bar and dumbbell plates that are detachably connected by bolts. The number of dumbbell plates can be configured at both ends of the grip bar according to actual needs. At the same time, the length of the dumbbell bar needs to be adjusted, which is more troublesome to operate.

[0003] Chinese patent CN222218525U discloses a novel adjustable dumbbell, consisting of a handle and weights on both sides of the handle. The weights are based on dumbbell plates as the core weight, and are limited by a positioning frame, which can effectively solve the problem of dumbbell plates easily wobbling. At the same time, by using positioning pins to cooperate with mounting holes on the positioning frame and dumbbell plate unit repositioning holes, the dumbbell plate units can be added or removed simply by inserting and removing the positioning pins, so as to achieve the purpose of increasing or decreasing the weight of the dumbbell.

[0004] However, the adjustable dumbbells mentioned above have the following drawbacks when used and assembled:

[0005] 1. First, the handle needs to be fitted onto the outside of the connecting rod and positioned in the middle. Then, the dumbbell plate set is fixed in the positioning frame with positioning pins to form a weight. During the assembly, since the dumbbell plate set is mounted on the connecting rod, it is fixed with positioning pins. The side plates on both sides are then fixed on the connecting rod and located on both sides of the dumbbell plate set. The installation process is quite complicated, with many parts, and it cannot produce a quick result during assembly, which is time-consuming and laborious for users.

[0006] 2. Secondly, the purpose of this adjustable dumbbell is for users to exercise, but due to its many structural features, it is relatively complex to manufacture, which undoubtedly increases the purchase cost. Utility Model Content

[0007] The purpose of this invention is to provide a simple and quick-assembly adjustable dumbbell to solve the problem of achieving a quick installation effect during adjustment and assembly, while reducing purchase costs.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a simple and quick-assembly adjustable dumbbell, comprising a handle, side plates, dumbbell plates, and a fixing knob. The cross-section of the dumbbell plates is equal to the cross-section of the side plates. Side plates are symmetrically and fixedly installed on both sides of the handle. A threaded hole is provided at the center of each side plate, and the threaded hole penetrates the side plate and extends into the interior of the handle. A screw is fixedly installed on the fixing knob, and the screw is embedded in the threaded hole, so that its rotation forms a threaded connection between the fixing knob and the side plates.

[0009] Preferably, multiple dumbbell plates are symmetrically installed on the side of the side plate, and each dumbbell plate has an insertion hole at its center. A fixing knob is installed on the side of the outermost dumbbell plate. The screw on the fixing knob passes through the insertion hole on the dumbbell plate and engages with the threaded hole to fix the dumbbell plates between the fixing knob and the side plate.

[0010] Preferably, the surface of the handle is provided with an anti-slip knurled pattern.

[0011] Preferably, the surface of the fixed knob is also provided with an anti-slip knurled pattern.

[0012] Preferably, each of the multiple dumbbell plates has a weight marking on its surface, and the thickness of dumbbell plates with different weights is different.

[0013] The beneficial effects of this utility model are:

[0014] 1. This simple and quick-assembly adjustable dumbbell uses side plates, dumbbell plates, and a fixing knob to align one or more dumbbell plates with the side plates. At this time, the insertion hole and the threaded hole are also aligned. The screw on the fixing knob passes through the insertion hole and forms a threaded connection with the threaded hole. After tightening, the installation is complete and it can be used. This process simplifies the installation operation, has fewer parts, and can achieve a quick installation effect, saving time and effort for users.

[0015] 2. This simple and quick-assembly adjustable dumbbell, with its side plates, dumbbell plates, and fixing knob, offers the same exercise benefits as existing dumbbells. However, due to its simpler structure and fewer features, it is easier to manufacture and process, thus reducing purchase costs and saving economic costs. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0024] Please see Figure 1-5 This utility model provides a technical solution: a simple and quick-assembly adjustable dumbbell, including a handle 1, side plates 2, dumbbell plates 3, and a fixing knob 4. The cross-section of the dumbbell plates 3 is equal to the cross-section of the side plates 2, which facilitates easy alignment during installation. The side plates 2 are symmetrically and fixedly installed on both sides of the handle 1. A threaded hole 5 is provided at the center of the side plates 2, and the threaded hole 5 penetrates the side plates 2 and extends into the interior of the handle 1. To be precise, the handle 1 has a hollow structure and is threaded on its inner side wall to form an internal thread for installation. A screw 6 is fixedly installed on the fixing knob 4. The screw 6 is embedded in the threaded hole 5, and its rotation forms a threaded connection between the fixing knob 4 and the side plates 2. The fixing knob 4, through the cooperation of the screw 6 and the threaded hole 5, can form a threaded connection between the two, providing a quick installation requirement for the later addition of dumbbell plates 3.

[0025] Specifically, multiple dumbbell plates 3 are symmetrically installed on the side of the side plate 2, and each dumbbell plate 3 has an insertion hole 7 at its center. A fixing knob 4 is installed on the side of the outermost dumbbell plate 3. The screw 6 on the fixing knob 4 passes through the insertion hole 7 on the dumbbell plate 3 and engages with the threaded hole 5 to fix several dumbbell plates 3 between the fixing knob 4 and the side plate 2.

[0026] As a preferred solution, the dumbbell plate 3 is aligned with the side plate 2. At this time, the insertion hole 7 and the threaded hole 5 are also aligned. The screw 6 on the fixing knob 4 passes through the insertion hole 7 and forms a threaded connection with the threaded hole 5. After tightening, the installation is completed and the product can be used. This process simplifies the installation operation, has fewer parts, and can achieve a quick installation effect during assembly, which saves time and effort for users.

[0027] Specifically, the surface of the handle 1 is provided with anti-slip knurling 8, and the surface of the fixed knob 4 is also provided with anti-slip knurling 8.

[0028] The anti-slip knurling 8 on the handle 1 increases friction between the user and the handle 1, making it easier to grip and use, and improving anti-slip performance. The anti-slip knurling 8 on the fixed knob 4 increases friction on the fixed knob 4 during the tightening process, making it easier to rotate and tighten.

[0029] Specifically, each of the multiple dumbbell plates 3 has a weight marking 9 on its surface, and the thickness of the dumbbell plates 3 with different weights is different. The weight marking 9 makes it easy for users to intuitively understand their needs. Since the multiple dumbbell plates 3 have the same cross-section, the thickness is different under different weights. Example

[0030] Please see Figure 6 This utility model provides another technical solution: a simple and quick-assembly adjustable dumbbell, including a handle 1, side plates 2, dumbbell plates 3, and a fixing knob 4. The cross-section of the dumbbell plates 3 is equal to the cross-section of the side plates 2. The side plates 2 are symmetrically and fixedly installed on both sides of the handle 1. A threaded hole 5 is opened at the center of the side plates 2, and the threaded hole 5 passes through the side plates 2 and extends into the interior of the handle 1. A screw 6 is fixedly installed on the fixing knob 4. The screw 6 is embedded in the threaded hole 5, and its rotation forms a threaded connection between the fixing knob 4 and the side plates 2.

[0031] Specifically, multiple dumbbell plates 3 are symmetrically installed on the side of the side plate 2, and each dumbbell plate 3 has an insertion hole 7 at its center. A fixing knob 4 is installed on the side of the outermost dumbbell plate 3. The screw 6 on the fixing knob 4 passes through the insertion hole 7 on the dumbbell plate 3 and engages with the threaded hole 5 to fix several dumbbell plates 3 between the fixing knob 4 and the side plate 2.

[0032] Specifically, the surface of the handle 1 is provided with anti-slip knurling 8, and the surface of the fixed knob 4 is also provided with anti-slip knurling 8.

[0033] Specifically, each of the multiple dumbbell plates 3 has a weight marking 9 on its surface, and the thickness of the dumbbell plates 3 corresponding to different weights is different.

[0034] The difference between this embodiment and Embodiment 1 is that the length of the handle 1 is different. In this embodiment, the handle 1 is lengthened, making it suitable for weightlifting exercises. At the same time, the anti-slip knurling 8 on the surface is symmetrically arranged on the handle 1, making it easy to grip for weightlifting exercises. Embodiment 1, on the other hand, is for dumbbell exercises. The purpose is diversified, but the structure remains the same, so as to improve applicability.

[0035] In specific implementation of this utility model: On a flat ground or workbench, first align one or more required dumbbell plates 3 with the side plate 2. At this time, the insertion hole 7 and the threaded hole 5 are also aligned. Then, pass the screw 6 on the fixing knob 4 through the corresponding insertion hole 7 in sequence and form a threaded connection with the threaded hole 5. After tightening, a fixed state is formed, and the installation is completed for use. It should be noted that during the tightening process, since the dumbbell plate 3 is rectangular in shape and the edge line is straight, when tightening on a flat ground, they fit together and the dumbbell plate 3 will not rotate. This process has been confirmed by those skilled in the art during installation.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
