Abstract
The present invention relates to a physical culture apparatus, particularly to an insertion type safety barbell. The insertion type safety barbell is composed of a grab handle, a filling card, a fixing ring, an upper semi-disc, a stopper ring, a bolt, a lower semi-disc and a longitudinal groove. The flat side planes of the upper semi-disc and the lower semi-disc and the lower semi-disc are respectively provided with a semi-annular groove which is concentric with the upper semi-disc and the lower semi-disc and has a rectangular cross section. The side walls at both ends of the grab handle are respectively provided with a longitudinal groove. A scale pan is sleeved on the grab handle and is movably matched with the grab handle. The fixing ring is placed in the annular groove which is formed by two semi-annular grooves of the upper semi-disc and the lower semi-disc. The stopper ring is simultaneously placed in the longitudinal groove and the linear groove of the upper semi-disc. As the stopper ring fixes the relative position relationship between the grab handle and the scale pan, the possibility that the scale pan is dropped from the grab handle is radically prevented, and the safety of barbell movement is greatly increased.
Description
Technical field
The present invention relates to a kind of sports apparatus, particularly relate to a kind of insertion type safety barbell.
Background technology
Existing barbell 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 barbell is lifted up and down; people's hand can apply certain moment of torsion to barbell; because the inertia of barbell 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 barbell exercise, this is a potential safety hazard.
Summary of the invention
The present invention provides a kind of insertion type safety barbell that can prevent that scale pan from rotating under effect of inertia for solving the deficiencies in the prior art.
The scheme that solves the technology of the present invention problem is: insertion type safety barbell is made of lever, filling card, retainer ring, first dish, baffle ring, bolt, second dish and cannelure.First dish and second dish are big or small identical semi-circular for a pair of shape.Having one on first dish and the flat side of second dish respectively, to coil concentric cross section with first dish and second be the semi-circular groove of rectangle, and the degree of depth of described semi-circular groove is half of thickness of first dish or second dish.Also have on the flat side of first dish side with first dish vertical and with cross section that described semi-circular groove joins be the straight shape groove of rectangle.The straight flange of first dish and second dish joins, and constitutes the scale pan of annular jointly.Lever is the cylindrical metal rod, with the termination of lever distance be holistic baffle ring for there is a circle 1/4 position of lever length with lever.A cannelure is respectively arranged on the sidewall at lever two ends.Retainer ring is that the cross section is the annulus of rectangle, and the diametric(al) in retainer ring inside has one to be the bolt of holistic vertical bar shaped with retainer ring.Scale pan is enclosed within on the lever and with lever and is in active relationship.Retainer ring is in the cannelure that first dish and the two halves cannelure of second dish constituted.Bolt is in the described straight shape groove of cannelure and first dish simultaneously.Fill card and be rectangular metal sheet, fill card and be in the cannelure between the outer end of the lateral surface of bolt and cannelure.
During installation, be enclosed within on the lever after only first dish and second dish need being merged, again retainer ring and bolt are inserted in the straight shape groove of cannelure that first dish and second dish form and first dish, bolt is fixing as a whole with first dish and second dish, and bolt is fixed the relative position of scale pan and lever.
Adopt such scheme, can reach following effect:
Because bolt is 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, the security that has improved barbell exercise greatly.

The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Insertion type safety barbell is made of lever 1, filling card 2, retainer ring 3, first dish 4, baffle ring 5, bolt 6, second dish 7 and cannelure 8.First dish 4 and second dish 7 are that a pair of shape is big or small identical semi-circular.Having one on first dish 4 and second dish 7 the flat side respectively, to coil 7 concentric cross sections with first dish 4 and second be the semi-circular groove of rectangle, the degree of depth of described semi-circular groove for first coil 4 or second coil half of 7 thickness.Also have on first dish flat side of 4 one with first coil 4 side vertical and with cross section that described semi-circular groove joins be the straight shape groove of rectangle.The straight flange of first dish 4 and second dish 7 joins, and constitutes the scale pan of annular jointly.Lever 1 is the cylindrical metal rod, is having a circle and lever 1 to be holistic baffle ring 5 with the termination of lever 1 distance for 1/4 position of lever 1 length.A cannelure 8 is respectively arranged on the sidewall at lever 1 two ends.Retainer ring 3 is that the cross section is the annulus of rectangle, and the diametric(al) in retainer ring 3 inside has one to be the bolt 6 of holistic vertical bar shaped with retainer ring 3.Scale pan is enclosed within on the lever 1 and with lever 1 and is in active relationship.Retainer ring 3 is in the cannelure that first dish 4 and second dish two halves cannelure of 7 constituted.Bolt 6 is in the described straight shape groove of cannelure 8 and first dish 4 simultaneously.Filling card 2 be rectangular metal sheet, fills and blocks in 2 cannelures 8 that are between the outer end of the lateral surface of bolt 6 and cannelure 8.
During installation, be enclosed within on the lever 1 after only first dish 4 and second dish 7 need being merged, again retainer ring 3 and bolt 6 inserted in the straight shape groove of cannelures that first dish 4 and second dish 7 form and first dish 4, bolt 6 is fixing as a whole with first dish 4 and second dish 7, and bolt 6 is fixed the relative position of scale pan and lever 1.
