The utility model aims at realizing through the following technical scheme: a dumbbell sheet 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 buffer sleeve is arranged in the circumferential direction of the box body and comprises a buffer air ring and side flanges arranged at two ends of the buffer air ring, the side flanges are connected with the box body, and an annular buffer gas cavity is formed in the buffer air 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 buffer 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 annular buffer air cavity is arranged in the buffer air ring, when the dumbbell piece collides with other objects, the annular buffer air cavity can play a good role in buffering, and the impact force between the dumbbell piece and the collided object is effectively reduced.
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 cushion sheath is made of rubber.
Preferably, the filler is formed by mixing basalt and portland cement.
The utility model has the advantages that: the utility model discloses a set up the cushion collar 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. 1 is a sectional view in one direction of the present invention.
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 buffer air ring, 7, an annular buffer air cavity, 8, a side flange, 9 and a flanging.
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 includes a box body, which 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 circumferential direction of the box body is provided with a buffer sleeve, and the buffer sleeve is made of rubber. The cushion collar includes buffering gas ring 6 and sets up the side flange 8 at 6 both ends of buffering gas ring, and buffering gas ring 6 and side flange 8 integrated into one piece. An annular buffer air cavity 7 is arranged in the buffer air ring 6. The side ribs 8 are embedded in the annular limiting grooves, so that the side ribs 8 can be flush with the surface of the box body.
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 buffer 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 annular buffer air cavity is arranged in the buffer air ring, when the dumbbell piece collides with other objects, the annular buffer air cavity can play a good role in buffering, and the impact force between the dumbbell piece and the collided object is effectively reduced.
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.
