Description

Technical Field

[0001] The utility model belongs to the technical field of fitness equipment, and in particular relates to a dumbbell with a high-safety locking mechanism. Background Art

[0002] As an auxiliary equipment for weightlifting and fitness exercises, dumbbells are easy to use and can be used to enhance muscle strength training, so they are often used by fitness enthusiasts. Dumbbells usually include a dumbbell rack, a counterweight and a grip. When adjusting the counterweight, the counterweight needs to be disassembled and assembled on the dumbbell rack. In the prior art, the patent document with patent application number 201620757677.4 states that in order to facilitate the disassembly of the counterweight, a dumbbell that disassembles the counterweight by rotating the grip has appeared. In order to prevent the grip from rotating relative to the dumbbell rack in use, a locking member and an unlocking button for locking the grip to prevent relative rotation are also provided on the dumbbell rack. However, the unlocking button is arranged near the grip on the dumbbell rack. Therefore, in actual use, when the user exercises with the grip in hand, it is easy to accidentally touch the unlocking button to cause the grip to rotate relative to the dumbbell rack, and there is a risk of the counterweight falling off the dumbbell rack. Utility Model Content

[0003] The utility model provides a dumbbell with a high-security locking mechanism, aiming to solve the problem that the unlocking button on the dumbbell used to unlock the locking mechanism between the hand grip and the dumbbell rack in the prior art is arranged at a position close to the hand grip on the dumbbell rack, so there is a risk that the user may accidentally touch the unlocking button, causing the hand grip to rotate relative to the dumbbell rack, resulting in the weight block falling off the dumbbell rack.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A dumbbell with a high-security locking mechanism, comprising:

[0006] A dumbbell base, provided with an unlocking member;

[0007] A dumbbell rack is detachably connected to the dumbbell base, and a hand grip is rotatably provided on the dumbbell rack;

[0008] A plurality of counterweights are arranged on the dumbbell rack and / or the dumbbell base. The counterweights on the dumbbell rack can be removed to the dumbbell base or the counterweights on the dumbbell base can be assembled to the dumbbell rack by rotating the hand grip; and

[0009] A locking mechanism, arranged on the dumbbell rack, wherein the locking mechanism includes a locking state and an unlocking state;

[0010] When the dumbbell rack is placed on the dumbbell base, the unlocking member releases the locking mechanism from locking the hand grip and the dumbbell rack, the locking mechanism is in an unlocked state, and the hand grip can rotate relative to the dumbbell rack;

[0011] When the dumbbell rack is separated from the dumbbell base, the unlocking member is separated from the locking mechanism, the locking mechanism is in a locked state, and the hand grip is locked with the dumbbell rack.

[0012] A further solution: the locking mechanism comprises a turntable arranged on the dumbbell rack and rotating synchronously with the hand grip, a slider slidably arranged on the dumbbell rack, and an elastic member arranged on the dumbbell rack and used to drive the slider to lock with the turntable;

[0013] When the dumbbell rack is placed on the dumbbell base, the slider slides away from the turntable and compresses the elastic member under the driving action of the unlocking member, the locking mechanism is in an unlocked state, and the hand grip can rotate relative to the dumbbell rack;

[0014] When the dumbbell rack is separated from the dumbbell base, the slider is separated from the unlocking member, and under the action of the elastic member, the slider slides toward the turntable and is locked with the turntable, the locking mechanism is in a locked state, and the hand grip is locked with the dumbbell rack.

[0015] Based on the above technical solution: by setting a way for the slider to lock or unlock with the turntable, the turntable can be easily adjusted to different weight positions by rotation. By setting an elastic member, after the dumbbell rack is lifted up and separated from the dumbbell base, the slider is locked with the turntable under the action of the elastic member, thereby preventing the turntable and the grip from rotating, which is safer.

[0016] A further solution: the slider is arranged at the lower side of the dumbbell rack, the slider is provided with a first inclined surface, the unlocking member is provided with a second inclined surface matching the first inclined surface, and a slot is provided between the slider and the dumbbell rack;

[0017] When the dumbbell rack is placed on the dumbbell base from top to bottom, the unlocking member enters the slot, and the first inclined surface drives the sliding block to slide away from the turntable by sliding downward along the second inclined surface.

[0018] Based on the above technical solution: by setting a first inclined surface on the slider and a second inclined surface on the unlocking piece, when the dumbbell rack is placed on the dumbbell base, the unlocking piece enters the slot and slides relative to each other through the two inclined surfaces, driving the slider to gradually separate from the turntable, and also facilitating the upward removal of the dumbbell rack.

[0019] A further solution is that a first connecting portion is provided on the turntable, and a second connecting portion is provided on the slider, and the first connecting portion is connected to the second connecting portion so that the slider and the turntable are locked.

[0020] A further solution: the first connecting part is a plurality of clamping blocks arranged around the turntable, the second connecting part is a clamping groove arranged on the slider, and the clamping block is inserted into the clamping groove to lock the slider and the turntable.

[0021] A further solution: the first connecting part is a plurality of slots arranged around the turntable, and the second connecting part is a block arranged on the slider, and the block is inserted into the slot to lock the slider and the turntable.

[0022] Based on the above technical solution: the above setting enables the turntable to rotate to different weight gears, which is convenient for adjusting the counterweight, and at the same time can be locked with the slider at each weight gear.

[0023] A further solution: a first limiting portion is provided on the lower side of the slider, and a second limiting portion is provided on the dumbbell base, and the first limiting portion cooperates with the second limiting portion to lock the dumbbell rack and the dumbbell base;

[0024] When the clamping block is inserted into the clamping slot, the first limiting portion is disengaged from the second limiting portion, and the dumbbell rack and the dumbbell base are unlocked;

[0025] When the clamping block is not inserted into the clamping slot, the first limiting portion cooperates with the second limiting portion, and the first limiting portion cooperates with the second limiting portion to lock the dumbbell rack and the dumbbell base.

[0026] Based on the above technical solution: when the user rotates the grip to adjust the weight, after the card block is engaged into the card slot, the slider is locked with the turntable, and the first limit part is disengaged from the second limit part, and the user can lift the dumbbell rack upward to separate it from the dumbbell base. When the card block does not enter the card slot, there is a risk that the slider is not locked with the turntable. At this time, the first limit part cooperates with the second limit part to lock the dumbbell rack with the dumbbell base, so the user cannot lift the dumbbell rack upward, thereby avoiding the risk of the weight block falling off when the user uses the dumbbell due to the card block not being able to get into the card slot, thereby having higher safety.

[0027] A further solution: the first limiting portion is a limiting block, and the second limiting portion is a limiting groove;

[0028] Alternatively, the first limiting portion is a limiting groove, and the second limiting portion is a limiting block.

[0029] Based on the above technical solution: the cooperation between the limit block and the limit groove makes the structure more optimized.

[0030] A further solution: the elastic member is a spring, the dumbbell rack and the slider are both provided with a spring mounting seat, and the spring is arranged between the two spring mounting seats.

[0031] A further solution: the hand grip rotates synchronously with the turntable via a rotating shaft, and the sliding direction of the slider is parallel to the axis of the rotating shaft.

[0032] The beneficial effects of the utility model are:

[0033] The utility model sets the unlocking piece on the dumbbell base, so that when the user needs to disassemble the counterweight, the user needs to first place the dumbbell rack on the dumbbell base, so that the unlocking piece on the dumbbell base releases the locking mechanism from locking the hand grip and the dumbbell rack, and then the hand grip can be rotated to disassemble the counterweight, and the disassembled counterweight will remain on the dumbbell base. After the user lifts the dumbbell rack upward to separate it from the dumbbell base, the locking mechanism will separate from the unlocking piece, so the locking mechanism will lock the hand grip and the dumbbell rack, so that when the dumbbell is used, the hand grip cannot rotate relative to the dumbbell rack, thereby preventing the counterweight from falling off. The utility model is safer to operate when disassembling the counterweight, and can effectively avoid misoperation. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] like Figures 1 to 7 As shown, this embodiment provides a dumbbell with a high-security locking mechanism, comprising:

[0046] The dumbbell base 3 is provided with an unlocking member 31;

[0047] A dumbbell rack 1 is detachably connected to the dumbbell base 3, and a hand grip 11 is rotatably provided on the dumbbell rack 1;

[0048] A plurality of counterweights are arranged on the dumbbell rack 1 and / or the dumbbell base 3. The counterweights on the dumbbell rack 1 can be removed to the dumbbell base 3 or the counterweights on the dumbbell base 3 can be assembled to the dumbbell rack 1 by rotating the hand grip 11. Specifically, a connecting mechanism for connecting the counterweights is provided on the hand grip 11; and

[0049] A locking mechanism, arranged on the dumbbell rack 1, wherein the locking mechanism includes a locking state and an unlocking state;

[0050] When the dumbbell rack 1 is placed on the dumbbell base 3, the unlocking member 31 releases the locking mechanism from locking the hand grip 11 and the dumbbell rack 1, the locking mechanism is in an unlocked state, and the hand grip 11 can rotate relative to the dumbbell rack 1;

[0051] When the dumbbell rack 1 is separated from the dumbbell base 3, the unlocking piece 31 is separated from the locking mechanism, and the locking mechanism is in a locked state. The hand grip 11 is locked with the dumbbell rack 1. At this time, the hand grip 11 cannot rotate relative to the dumbbell rack 1, thereby locking the counterweight on the dumbbell rack 1 to prevent it from falling.

[0052] Specifically, dumbbell racks 1 are provided on both sides of the hand grip 11 , each dumbbell rack 1 is provided with a locking mechanism, and two unlocking members 31 are provided on the dumbbell base 3 , and the two unlocking members 31 correspond to the two dumbbell racks 1 respectively.

[0053] In this embodiment, Figures 2 to 7 As shown, as a specific implementation of the locking mechanism, the locking mechanism includes a turntable 13 arranged on the dumbbell rack 1 and rotating synchronously with the hand grip 11, a slider 2 slidably arranged on the dumbbell rack 1, and an elastic member arranged on the dumbbell rack 1 and used to drive the slider 2 to lock with the turntable 13; in a specific structure, the hand grip 11 is a handle, and the hand grip 11 is connected to the turntable 13 for synchronous rotation through a rotating shaft 12.

[0054] When the dumbbell rack 1 is placed on the dumbbell base 3, the slider 2 slides away from the turntable 13 and compresses the elastic member under the driving action of the unlocking member 31. After the slider 2 is separated from the turntable 13, the locking mechanism is in an unlocked state, and the hand grip 11 can rotate relative to the dumbbell rack 1, so that the dumbbell rack 1 is placed on the dumbbell base 3 and the weights are disassembled;

[0055] When the dumbbell rack 1 is separated from the dumbbell base 3, the slider 2 is separated from the unlocking member 31, and the slider 2 slides toward the turntable 13 under the action of the elastic member and is locked with the turntable 13. The locking mechanism is in a locked state, and the hand grip 11 is locked with the dumbbell rack 1. At this time, the hand grip 11 and the turntable 13 cannot rotate relative to the dumbbell rack 1.

[0056] In this embodiment, the specific position of the slider 2 is preferably set on the lower side of the dumbbell rack 1, and a slider 2 mounting portion is provided on the lower side of the dumbbell rack 1. The slider 2 is slidably set on the slider 2 mounting portion, and the sliding direction of the slider 2 is parallel to the axis of the rotating shaft 12.

[0057] like Figure 2 , Figure 4 and Figure 5 As shown, as a specific structure for the unlocking member 31 to drive the slider 2 to slide, the slider 2 is provided with a first inclined surface 22, the unlocking member 31 is provided with a second inclined surface 311 matched with the first inclined surface 22, and a slot is provided between the slider 2 and the dumbbell rack 1;

[0058] When the dumbbell rack 1 is placed on the dumbbell base 3 from top to bottom, the unlocking member 31 enters the slot, and the first inclined surface 22 drives the slider 2 to slide away from the turntable 13 by sliding downward along the second inclined surface 311. When the dumbbell rack 1 is lifted up, under the action of the elastic member, the slider 2 slides back to its original position and locks with the turntable 13, and the unlocking member 31 is released from the slot.

[0059] In this embodiment, as a specific structure for locking the slider 2 and the turntable 13, a first connecting portion is provided on the turntable 13, and a second connecting portion is provided on the slider 2. The first connecting portion is connected to the second connecting portion to lock the slider 2 and the turntable 13.

[0060] Specifically, a first solution that can be adopted is: the first connecting part is a plurality of blocks 21 arranged around the turntable 13, and the second connecting part is a slot 131 arranged on the slider 2, and the block 21 is inserted into the slot 131 to lock the slider 2 and the turntable 13.

[0061] Alternatively, a second solution may be adopted: the first connection part is a plurality of slots 131 arranged around the rotating disk 13, the second connection part is a block 21 arranged on the slider 2, and the block 21 is inserted into the slots 131 to lock the slider 2 and the rotating disk 13. When adjusting the counterweight, the rotating disk 13 is rotated to make different slots 131 match with the block 21.

[0062] Among them, in this embodiment, Figure 2 and Figure 7 As shown, it is preferred that a plurality of protrusions 132 are arranged around a side surface of the turntable 13 close to the slider 2, and a slot 131 is formed between two adjacent protrusions 132. A block 21 is arranged on the slider 2. In the process of rotating the grip 11, in order to avoid the phenomenon that the block 21 is not inserted into the slot 131 due to the abutment between the protrusion 132 and the block 21 and the user lifts the dumbbell rack 1, in this embodiment, a first limiting portion is provided on the lower side of the slider 2, and a second limiting portion is provided on the dumbbell base 3. The first limiting portion cooperates with the second limiting portion to lock the dumbbell rack 1 with the dumbbell base 3. After the dumbbell rack 1 and the dumbbell base 3 are locked, the user cannot lift the dumbbell rack 1 upwards.

[0063] When the card block 21 is inserted into the card slot 131, the slider 2 is locked with the turntable 13, the user cannot rotate the grip 11, the first limiting portion is disengaged from the second limiting portion, the dumbbell rack 1 is unlocked from the dumbbell base 3, and the user can lift the dumbbell rack 1 upwards;

[0064] When the block 21 is not inserted into the slot 131, the slider 2 is not locked with the turntable 13, and there is a risk that the hand grip 11 can rotate relative to the dumbbell rack 1, causing the weight block to fall off. However, the first limiting portion cooperates with the second limiting portion, and the first limiting portion cooperates with the second limiting portion to lock the dumbbell rack 1 with the dumbbell base 3, and the user cannot lift up the dumbbell rack 1. Therefore, only after the block 21 is engaged into the slot 131, the user can lift up the dumbbell rack 1 to separate it from the dumbbell base 3, thereby having higher safety. Among them, the first limiting portion and the first inclined surface 22 are respectively located on opposite sides of the slider 2.

[0065] As a specific structure, such as Figures 2 to 4 As shown, the first limiting portion is a limiting block 32, and the second limiting portion is a limiting groove 23;

[0066] Alternatively, the first limiting portion is the limiting groove 23, and the second limiting portion is the limiting block 32. Specifically, the limiting block 32 abuts against the top wall of the limiting groove 23, thereby preventing the user from lifting the dumbbell rack 1 upward.

[0067] In this embodiment, the elastic member is a spring 24 , and spring 24 mounting seats are provided on the dumbbell rack 1 and the slider 2 , and the spring 24 is arranged between the two spring 24 mounting seats.

[0068] Working principle description:

[0069] When it is necessary to increase or decrease the weight on the dumbbell rack 1, the user places the dumbbell rack 1 on the dumbbell base 3 so that the unlocking member 31 enters the slot. At this time, due to the relative sliding of the first inclined surface 22 and the second inclined surface 311, the slider 2 slides away from the turntable 13 and compresses the elastic member under the driving action of the unlocking member 31. After the slider 2 is separated from the turntable 13, the hand grip 11 and the turntable 13 can rotate relative to the dumbbell rack 1, and the user can disassemble the weight by turning the handle. After the adjustment, the user lifts the dumbbell rack 1 upward to separate it from the dumbbell base 3, and the slider 2 is separated from the unlocking member 31. The slider 2 slides toward the turntable 13 under the resetting action of the elastic member and is locked with the turntable 13. At this time, the hand grip 11 is locked with the dumbbell rack 1, and the hand grip 11 and the turntable 13 cannot rotate relative to the dumbbell rack 1.

[0070] The present utility model is not limited to the above optional implementation modes. Under the premise of not conflicting with each other, the various schemes can be combined arbitrarily. Anyone can derive other forms of products under the inspiration of the present utility model. However, no matter what changes are made in their shapes or structures, all technical schemes that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
