Abstract

The utility model provides a fastening clamping hoop which is used in the field of fastening of parts. A clamping hoop strip (1) of the fastening clamping hoop is arranged to be in a long-strip structure. An ear ring I (4) and an ear ring II (5) are respectively arranged at two ends of the clamping hoop strip (1). A fastening bolt (2) simultaneously penetrates through through holes (6) in the ear ring I (4) and the ear ring II (5). The ear ring I (4) and the ear ring II (5) are respectively provided with a bending part (7) which bends toward the outer side of the clamping hoop strip (1). When a fastening bolt (3) is screwed on the fastening bolt (2), the fastening bolt (3) is arranged to be in a structure which fixedly abuts against the bending parts (7). The fastening clamping hoop is simple in structure, low in manufacturing cost and even in locking force, damage to a threaded part of the fastening bolt can be avoided, the fact that the tightening torque is canceled out during a tightening process is avoided, locking force is even, cost is greatly saved, assembling time is greatly shortened, assembling efficiency is greatly improved, and the assembling difficulty of workers is lowered.

Description

A kind of fastening clamp

Technical field

The utility model belongs to the fastening field of component, more particularly, relates to a kind of fastening clamp.

Background technique

At present, be used for the thermal shield of automobile exhaust system and metal hard tube fastening common clip structure as shown in Figure 3, it is stacked up and down the round steel band, link and the screw that form by two end part and is formed.Wherein, be carved with screw thread on the outer surface of folded end on the steel band, link is connected across the place, two end part that is stacked up and down, and push down the two end part that are stacked, the screw string is located in the containing space of link and the formation of cotton tie thread head, by rotating screw, the two ends of cotton tie are relatively moved, thereby reach the size of shrinking or enlarging the formed clip of firm belt.Because tap is on the steel band skin, height of thread is very shallow, and stressed little, namely fastening force is little, skid easily, particularly under the shock and vibration effect easily loosening, reliability is poor.

The model utility content

Technical problem to be solved in the utility model is: provide a kind of easy for installation, fastening force is large, is difficult for loosening, work safety, reliable fastening clamp under frequent impact, effect of vibration.

Solve above-described technical problem, the technological scheme that the utility model is taked is:

The utility model is a kind of fastening clamp, comprise shell ring, clamping bolt, tightening nut, described shell ring is set to strip structure, and the two end part of shell ring arrange respectively ear circle I and ear circle II, clamping bolt passes the through hole on ear circle I and the ear circle II simultaneously, the kink of a lateral buckling outside shell ring respectively is set on described ear circle I and the ear circle II, and when described tightening nut tightened on the clamping bolt, tightening nut was set to fixedly be resisted against the structure on the kink.

Comprise screw section and polished rod section on the described clamping bolt, described polished rod section is set to the structure that is connected with bolt end, described tightening nut is set to square shape structure, and the shell ring of described banded structure is set to be bent into the clip body of circular ring.

Described tightening nut is set to be fixedly mounted on the structure in the ear circle II outside, described fastening clamp also comprises sleeve pipe, when described clamping bolt was installed on ear circle I and the ear circle II, described sleeve pipe was set to be installed in the structure between bolt end and the ear circle I.

Offer a plurality of breach of arranging by the gap on the surface of described shell ring, described breach is strip structure.

Described fastening clamp banding is during to path, the gap that keeps 1-3mm between described ear circle I and the ear circle II.

Adopt the technical solution of the utility model, can obtain following beneficial effect:

Fastening clamp of the present utility model, simple in structure, low cost of manufacture, good springiness, coupling mechanism force are even, because shell ring is provided with a plurality of breach, so that the clip body has enough elasticity, can avoid damage is caused in the screw section of clamping bolt, avoid offsetting in rundown process the screw-down torque of partial nut, coupling mechanism force is even; The tightening nut fixed installation (riveted joint) of box structure is greatly saved cost and is shortened installation time, thereby improve efficiency of assembling on the ear circle II of fastening clamp, alleviates workman's assembling difficulty.

Description of drawings

Fig. 1 is the structural representation of fastening clamp described in the utility model;

Structural representation when Fig. 2 is fastening clamp banding described in the utility model;

Fig. 3 is the structural representation of fastening clamp of the prior art;

Be labeled as among the figure: 1, shell ring; 2, clamping bolt; 3, tightening nut; 4, ear circle I; 5, ear circle II; 6, through hole; 7, kink; 8, screw section; 9, polished rod section; 10, bolt end; 11, clip body; 12, sleeve pipe; 13, breach; 14, steel band; 15, link; 16, screw.

Embodiment

The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and working principle etc. are described in further detail:

Shown in accompanying drawing 1, accompanying drawing 2, the utility model is a kind of fastening clamp, comprise shell ring 1, clamping bolt 2, tightening nut 3, described shell ring 1 is set to strip structure, the two end part of shell ring 1 arrange respectively ear circle I 4 and ear circle II 5, clamping bolt 2 passes the through hole 6 on ear circle I 4 and the ear circle II 5 simultaneously, respectively arrange one to the kink 7 of shell ring 1 outer lateral buckling on described ear circle I 4 and the ear circle II 5, when described tightening nut 3 tightened on the clamping bolt 2, tightening nut 3 was set to fixedly be resisted against the structure on the kink 7.

Comprise screw section 8 and polished rod section 9 on the described clamping bolt 2, described polished rod section 9 is set to the structure that is connected with bolt end 10, described tightening nut 3 is set to square shape structure, such structure, so that the tightening nut 3 of box structure is on tightening to clamping bolt 2 time, tightening nut 3 can fixedly be resisted against on the kink 7, and the shell ring 1 of described banded structure is set to be bent into the clip body 11 of circular ring.The spacing that fastening clamp described in the utility model is regulated between ear circle I 4 and the ear circle II 5 by turn tightening nut 3, thereby the size of control clip body 11.

The optimum structure of described tightening nut 3 is the structures that are set to be fixedly mounted on ear circle II 5 outsides, described fastening clamp also comprises sleeve pipe 12, when described clamping bolt 2 was installed on ear circle I 4 and the ear circle II 5, described sleeve pipe 12 was set to be installed in the structure between bolt end 10 and the ear circle I 4.
