Abstract
The utility model relates to sports equipment, in particular to a movable lock-lever type safe dumbbell, which consists of a weak magnetic column, a slideway, a magnetic fixing rod, a strong magnetic axle, a grab handle, a poise pan, a transverse axle hole and a strong magnetic bar. The poise pan is sleeved on the grab handle and in movable fit with the grab handle; the strong magnetic axis in tight fit with the grab handle is arranged in the grab handle; the slideway with the opening on the circumference surface of the poise pan is formed on the poise pan in the diameter direction; and the transverse axle hole with the opening on the circumference surface of the grab handle is formed on the grab handle in the diameter direction, and the diameter of the transverse axle hole is equal to that of the poise pan. The dumbbell radically prevents the poise pan from slipping from the grab handle, greatly improves the safety of dumbbell sports, and has the advantage of convenient assembly and disassembly.
Description
Technical field
The utility model relates to a kind of sports apparatus, particularly relates to a kind of mobile locking bar formula safety dumbbell.
Background technology
Existing dumbbell constitutes with the counterweight that is threaded onto the lever two ends by irritating lead and the screwed lever in two ends usually.Because in the process that dumbbell is lifted up and down; people's hand can apply certain moment of torsion to dumbbell; because the inertia of dumbbell integral body and directly be subjected to the lever inertia of torsion to exist bigger difference, so through regular meeting counterweight was rotated counterclockwise and broke away from lever under effect of inertia situation appears.In case counterweight breaks away from lever, has and pounds the situation of hurting sb.'s feelings or smashing property, for dumbbell exercise, this is a potential safety hazard.
The utility model content
The utility model is for solving the deficiencies in the prior art, and a kind of mobile locking bar formula safety dumbbell that can prevent scale pan landing from the lever is provided.
The scheme that solves the utility model technical problem is: mobile locking bar formula safety dumbbell is made up of weak magnetic post, slideway, magnetic fixed bar, strong magnetic axis, lever, scale pan, transverse axis hole and strong bar magnet.Scale pan is enclosed within on the lever and with lever and is in active relationship, and there is the strong magnetic axis that becomes the tight fit relation with lever the inside of lever.The scale pan diametric(al) has the slideway of an opening on the periphery of scale pan, and the diametric(al) of lever has the transverse axis hole of the opening identical with the diameter of scale pan on the lever periphery.The outer end of slideway is the weak magnetic post that becomes the tight fit relation with slideway, and there is the magnetic fixed bar that is in active relationship with slideway the inside of slideway.A magnetic fixed bar end relative with slideway be different pole each other, and a magnetic fixed bar end relative with strong magnetic axis be different pole each other.Strong bar magnet is the bar magnet of a bar shaped separating with scale pan.
During installation, earlier scale pan is placed on the lever, the rotation scale pan makes slideway and transverse axis hole on an axial line, and at this moment, under the suction of strong magnetic axis, the magnetic fixed bar in the slideway combines with strong magnetic axis, and scale pan and lever are locked by the magnetic fixed bar.Need be when lever takes off with scale pan, only need the magnetic pole that strong bar magnet and magnetic fixed bar outer end is different to contact the outer end of weak magnetic post, the magnetic fixed bar shifts out and enters fully slideway from the transverse axis hole under the suction of strong bar magnet, this moment, scale pan can take off from lever smoothly.
Adopt such scheme, can reach following effect:
Since the magnetic fixed bar with the locking of the relative position relation of lever and scale pan, this has just fundamentally stopped the possibility of scale pan landing from the lever, has improved the security of dumbbell exercise greatly.
2. owing to only need to adopt the weak magnetic post outer end of strong bar magnet contact just can play the effect that unlocks, this makes loading and unloading of the present utility model very convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. weak magnetic post 2. chutes 3. magnetic fixed bar the last 4. magnetic axises 5. levers 6. scale pans 7. transverse axis hole the last 8. bar magnets
The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Mobile locking bar formula safety dumbbell is made up of weak magnetic post 1, slideway 2, magnetic fixed bar 3, strong magnetic axis 4, lever 5, scale pan 6, transverse axis hole 7 and strong bar magnet 8.Scale pan 6 is enclosed within on the lever 5 and with lever 5 and is in active relationship, and there is the strong magnetic axis 4 with 5 one-tenth tight fit relations of lever the inside of lever 5.Scale pan 6 diametric(al)s have the slideway 2 of an opening on the periphery of scale pan 6, and the diametric(al) of lever 5 has the transverse axis hole 7 of the opening identical with the diameter of scale pan 6 on lever 5 peripheries.The outer end of slideway 2 is and the weak magnetic post 1 of 2 one-tenth tight fit relations of slideway that the inside of slideway 2 has the magnetic fixed bar 3 that is in active relationship with slideway 2.The relative end of magnetic fixed bar 3 and slideway 2 is different pole each other, and the relative end of magnetic fixed bar 3 and strong magnetic axis 4 is different pole each other.Strong bar magnet 8 is bar magnets of a bar shaped separating with scale pan 6.
During installation, earlier scale pan 6 is placed on the lever 5, rotation scale pan 6 makes slideway 2 and transverse axis hole 7 on an axial line, at this moment, under the suction of strong magnetic axis 4, the magnetic fixed bar 3 in the slideway 2 combines with strong magnetic axis 4, and scale pan 6 and lever 5 are by 3 lockings of magnetic fixed bar.Need be when lever 5 takes off with scale pan 6, only need the magnetic pole that strong bar magnet 8 and magnetic fixed bar 3 outer ends are different to contact the outer end of weak magnetic post 1, magnetic fixed bar 3 shifts out and enters fully slideway 2 from transverse axis hole 7 under the suction of strong bar magnet 8, this moment, scale pan 6 can take off from lever 5 smoothly.
