Description

Technical Field

[0001] The utility model relates to the technical field of dumbbells, in particular to a dumbbell component. Background Art

[0002] Dumbbells are a simple piece of equipment used to enhance muscle strength training. Their main material is cast iron, and some are covered with a layer of rubber. Dumbbells are a popular piece of fitness equipment, so there are many types.

[0003] When users use dumbbells to exercise, they usually add dumbbell cakes to the grip to adjust the weight to their own preference. However, dumbbell cakes are usually connected to the grip by threads and then fixed with fasteners. However, due to long-term disassembly and installation of the threads, a certain degree of wear is inevitable, which may cause the connection between them to loosen, and there may be a risk of the dumbbell cakes detaching. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a dumbbell assembly to solve the problem mentioned in the above background technology. However, due to the long-term disassembly and installation of the threads, a certain degree of wear is inevitable, resulting in the loose connection, and there is a risk of the dumbbell disc detaching.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dumbbell assembly, including a grip and a placement seat, both side end faces of the grip are provided with threaded ends, an anti-sliding block is provided on the middle surface of the grip, two limit rings are fixedly installed at both ends of the grip near the anti-sliding block, a plurality of dumbbell cakes are movably installed at both ends of the grip, the dumbbell cakes are connected to the grip through threaded ends, the dumbbell cakes can be installed and disassembled on the grip through the threaded ends, and fastening blocks are movably installed on both sides of the grip, and the fastening blocks are connected to the grip through threaded ends.

[0006] By adopting the above technical scheme, the user selects a dumbbell cake that suits his weight and then installs the dumbbell cake on the grip rod through the threaded end of the grip rod. Then, the limiting ring provided on the grip rod can limit the dumbbell cake to a certain extent. Then, the anti-sliding block provided in the middle position of the grip rod can increase the friction between the user and the user's hand when exercising, preventing the risk of the hand slipping and causing injury to the person. Then, after the dumbbell cakes are installed, the fixing block is installed on the grip rod through the threaded end on the grip rod, so that the fixing block and the limiting ring cooperate to limit the dumbbell cake and prevent the dumbbell cake from falling off.

[0007] Preferably, both ends of the two fastening blocks are provided with through holes, and fastening bolts for fixing the fastening blocks are inserted into the through holes.

[0008] By adopting the above technical solution, after long-term installation and disassembly through the threads, a certain amount of wear will inevitably occur between the threads, resulting in a certain amount of looseness between the threads. In this case, the fastening bolts can be aligned with the through holes opened at both ends of the fastening block, and then the fastening bolts are rotated so that the fastening bolts are inserted into the fastening block. Then, both fastening bolts move inward to generate a certain clamping force, so that the fastening block can be better fixed to the grip rod, thereby preventing the risk of the dumbbell cake falling, thereby improving the safety of the dumbbell.

[0009] Preferably, a positioning hole is provided at the bottom of the limiting ring, and a clamping block is installed at the bottom position of the inner ends of both sides of the limiting ring.

[0010] By adopting the above technical solution, the dumbbell can be better fixed to the placement seat through the positioning hole opened at the bottom of the limiting ring, and then the clamping blocks installed at both ends of the limiting ring can limit the dumbbell to the placement seat.

[0011] Preferably, a placement groove matching the shape of the dumbbell cake is provided on the top surface of the placement seat, and two positioning columns are fixedly installed in the placement groove, and the two positioning columns can be connected to the positioning holes at the bottom of the limiting ring.

[0012] By adopting the above technical scheme, the dumbbell can be better fixed in the placement groove because the placement groove opened on the placement seat is consistent with the shape of the dumbbell cake, and then a positioning column is fixedly installed in the placement groove, and then the positioning column can be inserted into the positioning hole at the bottom of the limit ring to fix the dumbbell, thereby preventing the dumbbell body from rolling.

[0013] Preferably, two baffles are fixedly installed in the placement groove closer to the middle position, pull rods are movably inserted in the two baffles, springs are installed on the inner surfaces of the two baffles, a pull ring is fixedly installed on the inner end of the pull rod, and a positioning block is fixedly installed on the outer end of the pull rod.

[0014] By adopting the above technical solution, the pull ring is pulled inward so that the pull ring drives the pull rod to move inward, thereby allowing the pull rod to drive the positioning to cancel the restriction on the card block, so that the dumbbell can be better removed from the placement seat. Then, when the dumbbell needs to be placed in the placement seat, the pull ring is pulled to allow the pull rod to drive the positioning block to move, and then the dumbbell is placed on the placement seat. After the dumbbell is placed, the pull ring is released, so that the spring contracts to allow the pull rod to drive the positioning block to move to both sides, thereby limiting the card block on the limit ring, so that the dumbbell can be better limited, so that the dumbbell body is fixed to the placement seat, thereby preventing the dumbbell from rolling when not in use and affecting other people.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. A dumbbell assembly aligns the fastening bolts with the through holes opened at both ends of the fastening block, and then rotates the fastening bolts to insert the fastening bolts into the fastening block, and then both fastening bolts move inward to generate a certain clamping force, so that the fastening block is better fixed to the grip bar, thereby preventing the risk of the dumbbell cake falling, thereby improving the safety of the dumbbell.

[0017] 2. This dumbbell assembly aligns the positioning hole opened at the bottom of the limit ring with the positioning column on the placement seat, and then uses the placement seat to fix the dumbbell. Then the block installed in the limit ring will be stuck by the positioning block on the pull rod and fixed to the placement seat, thereby preventing the dumbbell from rolling when not in use and affecting other people.
