Description

A kind of fixture of disc

The utility model relate to a kind of on bar the fixing device of disc, it comprises the parts that match with bar and the parts that match with barbell can be opened or the mechanism of locking.

Mostly the disc fixture that weight lifting competition is used be with having the snap ring of screw-tightened mechanism, and the also useful fastening disc of screw-tightened mechanism snap ring that do not have uses in the playday occasion but latter event is many, because this device is more convenient when using.In the prior art, not having screw-tightened mechanism snap ring is to constitute with one section torque spring, and form handle with each terminal of torque spring, utilize handle that torque spring is oppositely unclamped in use, spring inside diameter is increased, after torque spring is placed in bar, remove constraint handle, torque spring is promptly held bar tightly under the restoring force effect, realizes disc is fixed in purpose on the bar.But prior art can only use thinner spring to make this fastener owing to be subjected to the restriction of elasticity modulus of materials, so it and the contact area very little (diameter because of the torque spring circle is also less) of disc, causes disc axial restraint effect relatively poor; On the other hand, the people less to grip, for example women and children use this fastener that bigger difficulty is arranged because she (he) be difficult to make torque spring oppositely to unclamp; This external use prior art can produce noise and wearing and tearing because of intermetallic friction during tightly because of disc.

The purpose of this utility model provides a kind ofly can axially have better fixed effect to disc, and the disc fixture of the non-band screw-tightened mechanism that can make things convenient for that the less people of grip uses.

The purpose of this utility model adopts following measure to realize: adopt two arc slips that respectively carry flange on it, be connected with a hinge mutually between the two, on two arc slips a retaining mechanism is set.Retaining mechanism of the present utility model is meant: fix a lock handle with another hinge on an arc slips, on lock handle, fix an end of an annular connecting pin again with hinge, and the other end of annular connecting pin schedules on another arc slips with the 3rd hinges fixing; Perhaps, be on an arc slips, to use hinge fixing and locking handle, on lock handle, fix a connecting ring with hinge, a recess that can match with connecting ring is set on another arc slips, form as existing key ring structure.

For making the utility model better fixed effect be arranged to disc, can be in the inboard of two arc slips, promptly with on the face that bar matches stud with rubber packing, perhaps/and on the flange of two arc slips, promptly stud with rubber packing with the disc place of combining.

The utility model is not owing to adopt torque spring structure of the prior art, and with annular connecting pin that has handle or connecting ring structure, and therefore leicht fallen D/A had in use both been opened easily, also locked easily; The utility model partly area that combines with disc in addition, promptly flange partly can do bigger, so it is fine to disc axial restraint effect; The 3rd, owing on arc slips inboard and arc slips flange, rubber packing is set, not only the disc fixed effect can be improved, but also device can be reduced bar and disc friction, the noise of avoiding effect each other to produce; The 4th, because the utility model structure, it can adopt the plastics manufacturing, but both weight reductions can reduce manufacturing cost again, can also more convenient use.

Description of drawings: Fig. 1 is the front view of most preferred embodiment of the present utility model, and the part that dots among the figure is the state of lock handle when opening.Fig. 2 is the vertical view of Fig. 1, has wherein showed the part-structure in the slips with broken section.

The utility model provides following two embodiment, below in conjunction with embodiment and accompanying drawing explanation.

First embodiment of the present utility model (annotates; Present embodiment does not provide accompanying drawing) be two arc slips to be linked together with hinge, be that two arc slips form a circle suitable with the bar external diameter with the bar place of matching at locking state.Each is provided with and the contacted flange of disc on two arc slips, and use hinge fixing and locking handle on an arc slips therein, on lock handle, fix a connecting ring with hinge again, a recess that can match with connecting ring is set on another arc slips, forms as existing key ring structure.These external two arc slips inboards, promptly match with bar place and two arc slips flanges and disc touching position of each arc slips is provided with rubber packing separately.Present embodiment in use, when being in stationary state, one end of connecting ring is to be placed in the recess set on the slips, under the acting in conjunction of handle and connecting ring and slips upper notch, two slips are tightly held tightly simultaneously and be fixed on the bar, and set flange is close proximity on the disc on the slips, thereby disc is fixed on the bar.When cocked handle and forward during swing handle, connecting ring is released, at this moment connecting ring can be taken out from the recess constrained of arc slips, remove slips fixing to bar, only in one side have hinge fix between two slips this moment, another side does not then have constraint, and two slips can rotate around fixed hinge.Connecting ring is to be in outside the handle at stationary state in the present embodiment.

Second embodiment of the present utility model is the most preferred embodiment that is provided by accompanying drawing.In most preferred embodiment,, respectively be provided with flange 5 and 1, two slips 6 and 9 on the slips 6 and 9 and fix with hinge 8 in one side referring to Fig. 1 and Fig. 2.On slips 6, be fixed with lock handle 3 with hinge 4.On handle 3, be provided with another pan, and another hinge 12 is set in this hole.Hinge 12 rigidly fixes an end of annular connecting pin 2, and the other end of annular connecting pin 12 has rigidly fixed another hinge 11.Pan set on 11 on hinge and the slips 9 matches.Constitute locking device 10 by hinge 4,11,12 and handle 3.For making the utility model that better fixed effect be arranged, be set with liner (13) and (14) of at least one usefulness rubber system in the inboard of each slips 6 and 9.On the outside of set flange 5 on each slips 6 and 9 and 1, the semicircular liner 7 with rubber system is set respectively on the face that itself and disc are in contact with one another promptly.

When most preferred embodiment of the present utility model used, when handle 3 unclamps when being in position shown in Fig. 1 dotted line, slips 6 can be done rotation among a small circle with 9 around hinge 8, and at this moment the position between slips 6 and 9 inboards can be bigger, is enough to be inserted on the bar at an easy rate.When handle 3 is fastened when being in solid line part shown in Figure 1, under the effect of handle 3, hinge 4,12 and 11 with two slips 6 and 9 lockings, make to have minimum position between both inboards, this position size should be suitable with the bar outside diameter, thereby holds tightly the barbell thick stick fixing.And the annular connecting pin is positioned at the handle inboard when locking state, and this can prevent that annular connecting pin from being opened by accident, also can have and use profile preferably.Owing to respectively be provided with rubber packing in two slips inboards, can obviously improve fixed effect to bar, and the rubber packing 7 of being located at the flange 5 and 1 outside both can improve disc fixing between axially, simultaneously also can alleviator to the friction of disc, the noise that produces between cancellation element and disc.

From above-described technical measures also as can be known, do not adopt screw-tightened of the prior art mechanism in the utility model, do not adopt the spiral torsion mechanism, so it can be made fully yet with plastic or other material.

Need in addition to specify that the annular connecting pin 2 in the utility model most preferred embodiment can directly be made the structure of a square frame shape, and two straight flanges of square frame shape structure promptly can be two each with slips and the fixing hinge fraction of handle.
