Abstract
The invention discloses a dumbbell preventing dumbbell pieces from rotating. The dumbbell comprises a dumbbell rod, the dumbbell pieces, threaded rods and Z-shaped clamping parts. The dumbbell rod is a hollow inner thread pipe, the number of the threaded rods is two, one end of each threaded rod is connected with the dumbbell rod through threads, each threaded rod is provided with a strip-shaped groove for mounting the Z-shaped clamping parts, one edge, used for clamping the corresponding dumbbell piece, of each Z-shaped clamping part is equal to the corresponding dumbbell piece in thickness, clamping grooves matched with the Z-shaped clamping parts are formed in middle connecting holes of the dumbbell pieces, the dumbbell pieces are connected with the threaded rods through the Z-shaped clamping parts, and fixed blocking nuts are arranged at the other ends of the two threaded rods respectively. The dumbbell has the advantages that the Z-shaped clamping parts arranged between the threaded rods and the dumbbell pieces limit rotation of the dumbbell pieces, and the dumbbell pieces are prevented from falling off.
Description
Technical field
The present invention relates to sports goods field, be specifically related to Demountable badminton racket.
Background technology
Existing dumbbell is all comprised of the nut of holding rod, dumbbell plate and solid dumbbell sheet, screw rod is fixed or is formed at two of holding rod, dumbbell plate is screwed onto on the screw rod at holding rod two by screwed hole, nut is screwed onto on screw rod in order to solid dumbbell sheet, user can increase or reduce according to the needs of self quantity of dumbbell plate again.
The weak point of existing dumbbell is: dumbbell bar is fixed dumbbell plate by single pole, easily cause dumbbell plate rotation, because two ends connect by nut, the loosening bolt that can drive of dumbbell plate exits, if just time process bolt all exit, dumbbell plate is come off, not only affected the effect of taking exercise, also can cause potential safety hazard.
Summary of the invention
The dumbbell plate that the present invention will solve present dumbbell is that single pole connects the problem that rotation comes off that is prone to.
In order to address the above problem, the scheme that the present invention proposes is: prevent the dumbbell that dumbbell dish rotates, comprise dumbbell bar, dumbbell plate, threaded rod and Z-type card, described dumbbell bar is hollow riffled tube, described threaded rod is two, two screw rod one end are threaded with dumbbell bar, on described threaded rod, be provided with a bar-shaped trough of laying a plurality of Z-type cards, described Z-type card is used for blocking one side of dumbbell plate and the thickness of dumbbell plate equates, in the middle of dumbbell plate, connecting hole is provided with the draw-in groove mating with Z-type card, dumbbell plate is connected with threaded rod by Z-type card, the other end of two threaded rods is provided with fixing shelves cap.
Adopt the advantage of technique scheme to be: the present invention arranges Z-type card between threaded rod and dumbbell plate, limited the rotation of dumbbell plate, dumbbell plate is first coordinated with threaded rod, again dumbbell bar is connected with threaded rod, to axially the fixing of dumbbell plate, make dumbbell be difficult for rotation and also can not come off out like this.Because being coordinates at dumbbell plate is first and threaded rod, make, in the whole precession dumbbell bars of unnecessary threaded rod, to make the two ends of dumbbell plate can not leave unnecessary threaded rod, thereby can prevent the infringement of threaded rod to foreign object.
The length of threaded rod should be less than or equal to dumbbell bar length 1/2nd, making can be by the whole precession dumbbell bar of threaded rod when there is no dumbbell plate.
Further, because user waits on hand in use, can produce sweat, also cause and skid; The hand grip portion surface of described dumbbell bar is provided with anti-slip veins.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention prevents the dumbbell that dumbbell dish rotates.
The specific embodiment
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated,
According to the dumbbell that dumbbell dish rotates that prevents of Fig. 1, comprise dumbbell bar 1, dumbbell plate 2, threaded rod 7 and Z-type card 4, dumbbell bar 1 is hollow riffled tube, threaded rod 7 is two, two screw rod 7 one end are threaded with dumbbell bar 1, on threaded rod 7, be provided with a bar-shaped trough 5 of laying a plurality of Z-type cards 4, Z-type card 4 equates with the thickness of dumbbell plate 2 for blocking one side of dumbbell plate 2, in the middle of dumbbell plate 2, connecting hole 3 is provided with the draw-in groove mating with Z-type card 4, dumbbell plate 2 is connected with threaded rod 7 by Z-type card 4, and the other end of two threaded rods 7 is provided with fixing shelves cap.
The present invention arranges Z-type card between threaded rod and dumbbell plate, limited the rotation of dumbbell plate, dumbbell plate has first been coordinated with threaded rod, then dumbbell bar is connected with threaded rod, so not only, to axially the fixing of dumbbell plate, make dumbbell be difficult for rotation and also can not come off out.Because being coordinates at dumbbell plate is first and threaded rod, make, in the many dumbbell bars of the whole precessions of unnecessary threaded rod, to make the two ends of dumbbell plate can not leave unnecessary threaded rod, thereby can prevent the infringement of threaded rod to foreign object.
The length of threaded rod 7 should be less than or equal to dumbbell bar 1 length 1/2nd, making can be by the whole precession dumbbell bar 1 of threaded rod 7 when there is no dumbbell plate.Because user waits on hand in use, can produce sweat, easily cause and skid; The hand grip portion surface of dumbbell bar 1 is provided with anti-slip veins 6.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; do not departing under the prerequisite of structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
Claims (2)
1. prevent the dumbbell that dumbbell dish rotates, comprise dumbbell bar, dumbbell plate, threaded rod and Z-type card, it is characterized in that: described dumbbell bar is hollow riffled tube, described threaded rod is two, two screw rod one end are threaded with dumbbell bar, on described threaded rod, be provided with a bar-shaped trough of laying a plurality of Z-type cards, described Z-type card is used for blocking one side of dumbbell plate and the thickness of dumbbell plate equates, in the middle of dumbbell plate, connecting hole is provided with the draw-in groove mating with Z-type card, dumbbell plate is connected with threaded rod by Z-type card, and the other end of two threaded rods is provided with fixing shelves cap.
2. the dumbbell that prevents that dumbbell dish from rotating according to claim 1, is characterized in that: the hand grip portion surface of described dumbbell bar is provided with anti-slip veins.
