Abstract
The invention relates to sports equipment, in particular to a turning/extending fixation type safety barbell consisting of round bars, locking screws, elliptic sleeves, weight plates, elliptic locking plates, snap rings, a handle and slots, wherein, the handle is a cylindrical metal bar; the snap rings integrated with the handle as a whole are arranged at the two ends of the handle; the elliptic sleeves integrated with the snap rings as a whole are arranged at the outer end of each snap ring; the cylindrical round bars are located in the elliptic sleeves; a plurality of elliptic locking plates are arranged on the lateral walls of the round bars; elliptic holes are formed at the center of the weight plates; slots are formed on the inner walls of the holes; and the elliptic locking plates are inserted in each slot. The invention can prevent the weight plates from falling from the sleeves during the weight-lifting process and greatly improve the safety of barbell exercise.
Description
Technical field
The present invention relates to a kind of sports apparatus, particularly relate to a kind of turning/extending fixation 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 turning/extending fixation 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: turning/extending fixation type safety barbell is made of round bar, lock nut, oval sleeve, scale pan, oval locking plate, snap ring, lever and slot.Lever is the cylindrical metal rod, the two ends of lever respectively have one with lever be holistic snap ring, the outer end of each snap ring be with snap ring be holistic oval sleeve, oval sleeve is that cross section is oval-shaped cylindrical shell, columniform round bar is in the oval sleeve and with oval sleeve and is in active relationship, have on the sidewall of round bar a plurality of equidistant, with the as a whole oval locking plate of round bar.Have groove on the sidewall of oval sleeve with on the corresponding position of oval locking plate.The oval-shaped jack that the middle part of scale pan has the outer wall with oval sleeve to be in active relationship, it is the circular diameter slot greater than the major axis of round bar that cross section is arranged on the inwall of jack.Described oval locking plate inserts in each slot.There is the lock nut that runs through round bar and oval sleeve the side of the end of oval sleeve.
During installation, earlier the rotation round bar is hidden in the oval sleeve oval locking plate, again scale pan is placed on the oval sleeve, and reverse rotation round bar again, oval locking plate stretches out and is inserted into the slot of scale pan from the groove of oval sleeve lateral wall.To get final product round bar and oval sleeve are fixing with lock nut again.
Adopt such scheme, can reach following effect:
1. because the scale pan middle part is the oval-shaped hole of matching with sleeve, and scale pan can't rotate around sleeve, this will strengthen the stability of scale pan.
2. because oval locking plate is inserted in the slot of scale pan, and this has just locked scale pan in sleeve position longitudinally, has avoided in the weight lifting process, scale pan comes off from sleeve, has improved the security of barbell exercise greatly.

Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A profile of Fig. 1.
Among the figure: 1. round bar 2. lock nut 3. oval sleeve 4. scale pans 5. oval locking plate 6. snap rings 7. levers 8. slots
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Turning/extending fixation type safety barbell is made of round bar 1, lock nut 2, oval sleeve 3, scale pan 4, oval locking plate 5, snap ring 6, lever 7 and slot 8.Lever 7 is the cylindrical metal rod, the two ends of lever 7 respectively have one to be holistic snap ring 6 with lever 7, the outer end of each snap ring 6 is to be holistic oval sleeve 3 with snap ring 6, oval sleeve 3 is that cross section is oval-shaped cylindrical shell, columniform round bar 1 is in the oval sleeve 3 and with oval sleeve 3 and is in active relationship, have on the sidewall of round bar 1 a plurality of equidistant, with the as a whole oval locking plate 5 of round bar 1.Have groove on the sidewall of oval sleeve 3 with on the oval locking plate 5 corresponding positions.The oval-shaped jack that the middle part of scale pan 4 has the outer wall with oval sleeve 3 to be in active relationship, it is the circular diameter slot 8 greater than the major axis of round bar 1 that cross section is arranged on the inwall of jack.Described oval locking plate 5 inserts in each slot 8.There is the lock nut 2 that runs through round bar 1 and oval sleeve 3 side of the end of oval sleeve 3.
During installation, earlier rotation round bar 1 is hidden in the oval sleeve 3 oval locking plate 5, scale pan 4 is placed on the oval sleeve 3 again, and the reverse rotation round bar 1 again, and oval locking plate 5 stretches out and is inserted into the slot 8 of scale pan 4 from the groove of oval sleeve 3 sidewalls.Again will be with lock nut 2 with round bar 1 and oval sleeve 3 fixing getting final product.
Claims (1)
