Such as: the invention discloses a dumbbell, which comprises a holding rod and dumbbell pieces, wherein threaded holes with two communicated ends are formed in the holding rod, one ends of two screws respectively penetrate through holes in the dumbbell pieces and then are connected to the two ends of the holding rod in a threaded mode, and hand-turning caps are fixed to the other ends of the two screws. The surface of the holding part of the holding rod is provided with anti-skid grains. When the dumbbell piece is used, the dumbbell piece can often collide with the ground or other objects, so that the dumbbell piece is easy to damage the dumbbell piece and the ground or other objects are easy to damage.

Disclosure of Invention

The utility model aims at solving current dumbbell piece in the use, dumbbell piece can often bump with ground or other objects, on the one hand easily gouge dumbbell piece itself, and on the other hand hits the problem of damaging ground or other objects easily, provides a dumbbell piece that possesses buffer function, can effectively solve above-mentioned problem.

The utility model aims at realizing through the following technical scheme: a dumbbell sheet with a buffering function comprises a disc-shaped box body, wherein fillers are arranged in the box body, and a shaft sleeve is arranged in the center of the box body; the protective sleeve is arranged on the circumferential direction of the box body and comprises a ring and side flanges arranged at two ends of the ring, the side flanges are connected with the box body, and a plurality of ribs are arranged on the inner side of the ring.

The utility model discloses in, the main weight of dumbbell piece is produced by the filler in the box body, and what of accessible change filler adjusts the weight of dumbbell piece. The shaft sleeve in the center of the box body is used for connecting the holding rod of the dumbbell. The protective sleeve is made of soft materials such as rubber and the like, is arranged in the circumferential direction of the dumbbell sheet, plays a role in buffering, reduces the impact force between the dumbbell sheet and the collided object, and protects the dumbbell sheet and the collided object. The setting can increase the intensity of protective sheath on the one hand at the inboard rib of ring, and on the other hand because the rib is located between ring and the box body for form certain space between ring and the box body, when making dumbbell piece and other object clashes, form certain buffering space, improve buffering effect.

Preferably, the box body is formed by connecting a first half box body and a second half box body. The box body is formed by connecting a first half box body and a second half box body, so that fillers can be conveniently filled into the box body.

Preferably, two ends of the shaft sleeve are respectively provided with a flanging. The flanging that is located the axle sleeve both ends can carry on spacingly to half box body of first box body and second, makes both buckles form a complete box body together. The flanges at the two ends of the shaft sleeve can be formed by stamping.

Preferably, the two ends of the shaft sleeve are respectively provided with a buffer sheet. The buffer plate can play a role in buffering between two adjacent dumbbell plates.

Preferably, the outer edges of the two ends of the box body are respectively provided with an annular limiting groove, and the side flanges are embedded into the annular limiting grooves. Through setting up annular spacing groove in the outward flange department at box body both ends, during the side flange embedding annular spacing groove for the side flange can with box body surface parallel and level.

Preferably, the filler is formed by mixing basalt and portland cement.

Preferably, the protective sleeve is made of rubber.

The utility model has the advantages that: the utility model discloses a set up the protective sheath on the circumferencial direction of dumbbell piece, can play the cushioning effect, reduce and hit the impact force between the object, protection dumbbell piece and the object that is hit.

Fig. 2 is a cross-sectional view in another direction of the present invention.

Fig. 3 is a cross-sectional view of the bushing.

In the figure: 1. the box comprises a first half box body, a second half box body, 3, fillers, 4, a shaft sleeve, 5, a buffer sheet, 6, a ring, 7, side flanges, 8, ribs, 9 and turned edges.

Detailed Description

The invention will be further described with reference to the following detailed description and accompanying drawings.

Example 1:

as shown in fig. 1 to 3, a dumbbell sheet with a buffering function comprises a box body, wherein the box body is disc-shaped. The box body is formed by connecting a first half box body 1 and a second half box body 2. The box body is filled with fillers. The filler is formed by mixing basalt and portland cement. The center of the box body is provided with a shaft sleeve 4, and two ends of the shaft sleeve 4 are respectively provided with a flanging 9. The turn-ups 9 can be spacing to first half box body 1 and second half box body 2, make both the lock joint form a complete box body together. The flanges 9 at the two ends of the shaft sleeve 4 can be formed by stamping. The two ends of the shaft sleeve 9 are provided with buffer sheets 9, and the buffer sheets 9 are made of rubber. The buffer plates 9 can play a role of buffering between two adjacent dumbbell plates. The outer edges of the two ends of the box body are provided with annular limiting grooves.

The protective sleeve is arranged on the circumferential direction of the box body and made of rubber. The protective sleeve comprises a ring 6 and side flanges 7 arranged at two ends of the ring 6, wherein the ring 6 and the side flanges 7 are integrally formed. The side ribs 7 are embedded in the annular limiting grooves, so that the side ribs 7 can be flush with the surface of the box body. The inner side of the ring 6 is provided with a plurality of ribs 8. The ribs 8 are arranged in an annular array on the inside of the loops 6.

The utility model discloses in, the main weight of dumbbell piece is produced by the filler in the box body, and what of accessible change filler adjusts the weight of dumbbell piece. The shaft sleeve in the center of the box body is used for connecting the holding rod of the dumbbell. The protective sleeve is arranged on the circumference direction of the dumbbell sheet, plays a role in buffering, reduces the impact force between the dumbbell sheet and the collided object, and protects the dumbbell sheet and the collided object. The setting can increase the intensity of protective sheath on the one hand at the inboard rib of ring, and on the other hand because the rib is located between ring and the box body for form certain space between ring and the box body, when making dumbbell piece and other object clashes, form certain buffering space, improve buffering effect.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the principles of the present invention.
