Description

Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, and in particular relates to a dumbbell with an anti-slip structure. Background Technology

[0002] Dumbbells are a simple piece of equipment used for training to increase muscle strength. They usually consist of a bar and two counterweights in the form of balls or discs attached to the ends. There are also designs similar to miniature barbells, which are short iron bars with circular iron plates of different weights attached to the ends.

[0003] When using traditional dumbbells, users typically hold the long bar. Because the bar is made of metal and has a smooth surface, the user's hands are prone to slipping on it. With prolonged use, the user's hands will sweat more, which will increase the slipping effect. This not only affects the user's workout, but in severe cases, the dumbbell may also slip off the user's hand, affecting the surrounding equipment or people. Utility Model Content

[0004] The purpose of this invention is to provide a dumbbell with an anti-slip structure. Specifically, an upper and lower plastic anti-slip sleeve are installed on the grip. Both the upper and lower plastic anti-slip sleeves have several arc-shaped protrusions and several strip-shaped protrusions to increase friction, preventing the user from slipping when gripping. Even with sweat, there is still significant friction, resulting in greater stability during use and improved training effectiveness. This solves the problem of traditional dumbbells, where the long bar is made of metal with a smooth surface, causing the user's hands to easily slip on the bar. Furthermore, prolonged use leads to increased sweating, further increasing slippage and affecting the user's workout. In severe cases, the dumbbell may even slip off the hand.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a dumbbell with an anti-slip structure, including a grip bar. Limiting discs are fixedly connected to both the left and right sides of the grip bar. A threaded rod is fixedly connected to the side of each limiting disc that is furthest from it. The dumbbell also includes:

[0007] An anti-slip mechanism is provided on the outside of the limiting plate. The anti-slip mechanism includes an upper plastic anti-slip sleeve and a lower plastic anti-slip sleeve. Both the upper and lower plastic anti-slip sleeves are fitted on the outside of the grip bar. Several arc-shaped protrusions and several strip-shaped protrusions are fixedly connected to the outer surfaces of the upper and lower plastic anti-slip sleeves.

[0008] The upper and lower plastic anti-slip sleeves are both semi-circular in shape, and the sides of the upper and lower plastic anti-slip sleeves that are close to each other are both semi-circular grooves. The upper and lower plastic anti-slip sleeves fit into the grip bar through the semi-circular grooves.

[0009] Furthermore, positioning blocks are fixedly connected to the inner sides of both the upper and lower plastic anti-slip sleeves. The upper plastic anti-slip sleeve has several insertion holes, and the top plane of the lower plastic anti-slip sleeve has several threaded holes. After the upper and lower plastic anti-slip sleeves are installed with the grip, screws are inserted into the insertion holes and threadedly connected to the threaded holes on the lower plastic anti-slip sleeve, thereby fastening the upper and lower plastic anti-slip sleeves to the grip.

[0010] The socket is used to insert screws, and the threaded hole corresponds to the position of the socket.

[0011] Furthermore, the top and bottom of the grip are provided with mating grooves, which are adapted to the shape of the positioning block. The grip is inserted into the positioning block through the mating grooves. The positioning block and the mating grooves cooperate to position the upper and lower plastic anti-slip sleeves. The positioning block is used to position and install the upper and lower plastic anti-slip sleeves, and to make the upper and lower plastic anti-slip sleeves more stable after installation.

[0012] Furthermore, the threaded rod is fitted with several inserts, and several protrusions are fixedly connected to both sides of each insert. Several arc-shaped protrusions are provided on the outer surface of the insert.

[0013] Furthermore, a number of friction protrusions are fixedly connected to the side of the limiting disc facing the insert, and a locking threaded ring is threadedly connected to the threaded rod. The locking threaded ring is used to lock and fix the multiple inserts. After the multiple inserts are inserted into the threaded rod, the locking threaded ring is installed on the threaded rod.

[0014] Furthermore, there is a gap between the upper and lower plastic anti-slip sleeves and the limiting plate, and both the upper and lower plastic anti-slip sleeves are designed with a high center and low sides.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates an anti-slip mechanism, specifically by installing an upper and lower plastic anti-slip sleeve on the grip bar. Both the upper and lower plastic anti-slip sleeves are equipped with several arc-shaped protrusions and several strip-shaped protrusions to increase friction, preventing the user from slipping when gripping. Even when sweating, the grip remains highly resistant, resulting in greater stability during use and improved training effectiveness.

[0017] 2. This utility model, by setting convex strips and arc-shaped protrusions, specifically, after the insert is inserted into the threaded rod, the friction between the convex strips increases the friction force, and the friction between the inserts also increases under the action of the convex strips, so that there will be no movement. Since there are several arc-shaped protrusions on the insert, the dumbbell will not roll after it is placed on the ground.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] 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 scope of protection of the present utility model.

[0028] Please see Figures 1-5 As shown, this utility model is a dumbbell with an anti-slip structure, including a grip bar 1, with limiting plates 11 fixedly connected to both the left and right sides of the grip bar 1, and threaded rods 12 fixedly connected to the sides of the two limiting plates 11 that are far apart from each other, and also including:

[0029] Anti-slip mechanism 2 is located on the outside of the limiting plate 11. Anti-slip mechanism 2 includes an upper plastic anti-slip sleeve 21 and a lower plastic anti-slip sleeve 22. Both the upper plastic anti-slip sleeve 21 and the lower plastic anti-slip sleeve 22 are fitted onto the outside of the grip bar 1. Several arc-shaped protrusions 211 and several strip-shaped protrusions 212 are fixedly connected to the outer surface of both the upper plastic anti-slip sleeve 21 and the lower plastic anti-slip sleeve 22. After the upper plastic anti-slip sleeve 21 and the lower plastic anti-slip sleeve 22 are installed on the grip bar 1, the presence of several arc-shaped protrusions 211 and several strip-shaped protrusions 212 on both the upper plastic anti-slip sleeve 21 and the lower plastic anti-slip sleeve 22 increases the friction, preventing the user from slipping when gripping. Even when sweating, the grip has a large friction force, making it more stable during use and improving the training effect.

[0030] The upper plastic anti-slip sleeve 21 and the lower plastic anti-slip sleeve 22 are both semi-circular in shape, and the sides of the upper plastic anti-slip sleeve 21 and the lower plastic anti-slip sleeve 22 that are close to each other are both semi-circular grooves. The upper plastic anti-slip sleeve 21 and the lower plastic anti-slip sleeve 22 fit into the grip bar 1 through the semi-circular grooves.

[0031] Positioning blocks 221 are fixedly connected to the inner sides of the upper plastic anti-slip sleeve 21 and the lower plastic anti-slip sleeve 22. Several insertion holes 24 are opened on the upper plastic anti-slip sleeve 21, and several threaded holes 23 are opened on the top plane of the lower plastic anti-slip sleeve 22.

[0032] The socket 24 is used to insert screws, and the threaded hole 23 is positioned corresponding to the socket 24.

[0033] The top and bottom of the grip bar 1 are provided with docking grooves 15. The docking grooves 15 are adapted to the shape of the positioning block 221. The grip bar 1 is inserted into the positioning block 221 through the docking grooves 15. The positioning block 221 and the docking grooves 15 are used to position the upper plastic anti-slip sleeve 21 and the lower plastic anti-slip sleeve 22.

[0034] Several inserts 13 are fitted onto the threaded rod 12. Several protrusions 131 are fixedly connected to both sides of the inserts 13. Several arc-shaped protrusions 132 are provided on the outer surface of the inserts 13. After the inserts 13 are inserted into the threaded rod 12, the friction between the protrusions 111 and 131 increases the friction force. The friction between the inserts 13 is also increased by the action of the protrusions 131, so there will be no movement. Since there are several arc-shaped protrusions 132 on the inserts 13, the dumbbell will not roll after it is placed on the ground.

[0035] The limiting plate 11 has several friction protrusions 111 fixedly connected to the side facing the insert 13, and the threaded rod 12 is threadedly connected to a locking threaded ring 14, which is used to lock and fix the multiple inserts 13.

[0036] There is a gap between the upper plastic anti-slip sleeve 21 and the lower plastic anti-slip sleeve 22 and the limiting plate 11. Both the upper plastic anti-slip sleeve 21 and the lower plastic anti-slip sleeve 22 are designed with a high center and low sides.

[0037] One specific application of this embodiment is:

[0038] In use, the upper plastic anti-slip sleeve 21 and the lower plastic anti-slip sleeve 22 are both connected to the docking groove 15 on the grip bar 1 through the positioning block 221, and the upper plastic anti-slip sleeve 21 and the lower plastic anti-slip sleeve 22 are positioned and installed on the grip bar 1. Then, the screw is inserted into the insertion hole 24 and threadedly connected to the threaded hole 23 on the lower plastic anti-slip sleeve 22, thereby fastening the upper plastic anti-slip sleeve 21 and the lower plastic anti-slip sleeve 22 to the grip bar 1. This method facilitates the installation of the upper plastic anti-slip sleeve 21 and the lower plastic anti-slip sleeve 22 and makes it easy to disassemble and replace them later. Since the upper plastic anti-slip sleeve 21 and the lower plastic anti-slip sleeve 22 are provided with several arc-shaped protrusions 211 and several strip-shaped protrusions 212, they are used to increase the friction, so that the user will not slip when gripping, and even when sweating, there is still a large friction, which makes it more stable during use and improves the training effect.

[0039] Then, according to training needs, several inserts 13 are inserted into the threaded rod 12. Since the limiting plate 11 is provided with friction protrusions 111, the inserts 13 can increase the friction after contacting the limiting plate 11, making it difficult for the inserts 13 to rotate. Furthermore, since both sides of the inserts 13 are provided with several protrusions 131, the friction can be increased, preventing the inserts 13 from moving. Finally, the locking threaded ring 14 is installed on the threaded rod 12 to lock and fix the multiple inserts 13. When the inserts 13 are installed and the dumbbell is placed on the ground, since the inserts 13 are provided with several arc-shaped protrusions 132, the dumbbell will not roll after being placed on the ground.
