Abstract
Description
Technical Field
[0001] This utility model relates to the field of fitness equipment technology, and in particular to an adjustable dumbbell. Background Technology
[0002] Dumbbells are an auxiliary tool for weightlifting and fitness exercises. With the increasing demand for fitness, dumbbells, as a relatively simple and commonly used piece of equipment, have become a top choice for fitness enthusiasts. Smaller than a barbell, they are named dumbbells because they are silent during exercise. A dumbbell consists of handles and weight blocks mounted on both sides of the handles. Depending on the desired weight, different numbers of weight blocks can be installed on the handles.
[0003] The existing dumbbells are complicated to change when changing weights. They usually use screws and bolts to install and remove weights. At the same time, the weights can become loose due to shaking during use, which affects the user's use and requires constant tightening. Therefore, we propose an adjustable dumbbell. Utility Model Content
[0004] The main purpose of this utility model is to provide an adjustable dumbbell that can effectively solve the problem of complicated operation when changing weights in existing dumbbells. Usually, screws and bolts are used to install and remove weights. At the same time, during the use of dumbbells, shaking can cause the weights to loosen, affecting the use of the exerciser, and requiring constant tightening.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] An adjustable dumbbell includes a handle, with main weights on both sides of the handle, a middle weight connected to the side of the main weights, and an outer weight connected to one side of the middle weights.
[0007] A locking mechanism is provided on the same side of the main weight block and the intermediate weight block, and an installation mechanism is provided on the same side of the intermediate weight block and the outer weight block, and the locking mechanism and the installation mechanism are adapted to each other.
[0008] Furthermore, the locking mechanism includes a positioning groove located at the center, rotating engagement areas located on opposite sides of the positioning groove, a slot connected to one side of the rotating engagement area, a retaining ring located above the slot, and a positioning steel ball located on one side of the positioning groove.
[0009] Furthermore, the installation mechanism includes a positioning protrusion located at the center, connecting rings located on opposite sides of the positioning protrusion, double shoulder buckles fixedly installed on both connecting rings, and a positioning groove located on one side of the positioning protrusion.
[0010] When installed, the shoulder buckles are secured by the retaining rings, and the positioning steel balls are precisely engaged in the positioning grooves.
[0011] During disassembly, the positioning steel ball disengages from the positioning groove, and the shoulder buckles disengage from the retaining ring. At this point, the shoulder buckles rotate into the groove.
[0012] Furthermore, the positioning protrusion is positioned opposite to and adapted to the positioning groove, and the positioning groove is adapted to the positioning steel ball.
[0013] Furthermore, the shape and size of the rotating snap-in area and the snap-in slot are the same as those of the shoulder buckles.
[0014] By adopting the above technical solution, this utility model can achieve both installation and disassembly states through the locking and installation mechanisms. During installation, first align the positioning protrusion of the middle weight block with the positioning groove of the main weight block, then rotate the middle weight block to rotate the shoulder buckles into the grooves. At this point, the shoulder buckles will be secured by the retaining ring. When the positioning steel ball is precisely engaged in the positioning groove, the middle weight block is installed. The operation for installing the outer weight block is the same as described above. When weight reduction is required (during disassembly), rotate the outer weight block to disengage the positioning steel ball from the positioning groove, and then the shoulder buckles will disengage from the retaining ring. When the outer weight block can no longer rotate, the shoulder buckles are now inside the grooves, and the outer weight block can be removed, thus disassembling it. The operation for disassembling the middle weight block is the same as described above.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. This utility model, through its locking and installation mechanisms, enables the rapid installation and disassembly of the intermediate and outer weights. The positioning grooves and protrusions first position the adjacent main weights and intermediate weights, or the intermediate and outer weights. Then, the shoulder buckles are placed in the rotating insertion area, and then rotated to insert them into the slots. The buckle rings secure the shoulder buckles within the slots. Through the above operations, the intermediate and outer weights can be quickly installed and disassembled, making it more convenient and easy to use.
[0017] 2. This utility model, through the setting of positioning steel balls and positioning grooves, can achieve the locking point fixation of adjacent main body weight blocks and intermediate weight blocks or intermediate weight blocks and outer weight blocks when the shoulder buckles are rotated into the grooves, effectively preventing the intermediate weight blocks and outer weight blocks from loosening and better meeting the needs of fitness users.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] like Figure 1-4 As shown, an adjustable dumbbell has a main weight block 2 on both sides of the handle 1, a middle weight block 3 connected to the side of the main weight block 2, and an outer weight block 4 connected to one side of the middle weight block 3.
[0026] A locking mechanism is provided on the same side of the main weight block 2 and the intermediate weight block 3, and an installation mechanism is provided on the same side of the intermediate weight block 3 and the outer weight block 4. The locking mechanism and the installation mechanism are adapted to each other.
[0027] In this embodiment, the intermediate weight block 3 and the outer weight block 4 can be installed and removed, and can be operated according to weight requirements to meet the usage needs of different groups of people.
[0028] The locking mechanism includes a positioning groove 5 located at the center, a rotating locking area 7 located on both sides of the positioning groove 5, a locking groove 8 connected to one side of the rotating locking area 7, a locking ring 9 located above the locking groove 8, and a positioning steel ball 6 located on one side of the positioning groove 5.
[0029] The mounting mechanism includes a positioning protrusion 10 located at the center, connecting rings 12 on both sides of the positioning protrusion 10, double shoulder buckles 13 fixedly installed on both connecting rings 12, and a positioning groove 11 on one side of the positioning protrusion 10.
[0030] Specifically, the locking and installation mechanisms enable the rapid installation and removal of the intermediate weight 3 and the outer weight 4. The positioning groove 5 and positioning protrusion 10 first position the adjacent main weight 2 and intermediate weight 3 or intermediate weight 3 and outer weight 4. Then, the shoulder buckle 13 is placed in the rotating insertion area 7 and rotated into the slot 8. The buckle ring 9 secures the shoulder buckle 13 in the slot 8. Through the above operations, the intermediate weight 3 and the outer weight 4 can be quickly installed and removed, making it more convenient and easy to use.
[0031] Furthermore, during installation, the shoulder buckles 13 are secured by the retaining rings 9, and the positioning steel balls 6 are precisely engaged within the positioning grooves 11.
[0032] During disassembly, the positioning steel ball 6 disengages from the positioning groove 11, and the shoulder buckles 13 disengage from the retaining ring 9. At this time, the shoulder buckles 13 rotate into the groove 8.
[0033] The positioning protrusion 10 and the positioning groove 5 are positioned opposite each other and are compatible, and the positioning groove 11 is compatible with the positioning steel ball 6. The positioning steel ball 6 and the positioning groove 11 are designed to fix the adjacent main weight block 2 and the middle weight block 3 or the middle weight block 3 and the outer weight block 4 when the shoulder buckle 13 is rotated into the groove 8, effectively preventing the middle weight block 3 and the outer weight block 4 from loosening, and better meeting the needs of fitness users.
[0034] The shape and size of the rotating snap-in area 7 and the slot 8 are the same as those of the double shoulder buckle 13.
[0035] It should be noted that this utility model is an adjustable dumbbell. When installing the middle weight 3 or the outer weight 4, first align the positioning protrusion 10 of the middle weight 3 with the positioning groove 5 of the main weight 2, and then rotate the middle weight 3 to rotate the shoulder buckle 13 into the groove 8. At this time, the shoulder buckle 13 will be fastened under the limit of the buckle ring 9. When the positioning steel ball 6 is just engaged in the positioning groove 11, the installation of the middle weight 3 is achieved. The operation when installing the outer weight 4 is the same as the above operation method.
[0036] When weight reduction is required (during disassembly), rotate the outer weight 4 to disengage the positioning steel ball 6 from the positioning groove 11. Then, the shoulder buckles 13 will disengage from the retaining ring 9. When the outer weight 4 can no longer rotate, the shoulder buckles 13 will rotate into the groove 8, and then the outer weight 4 can be removed, thus disassembling the outer weight 4. The operation for disassembling the middle weight 3 is the same as the above operation method.
[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
