Abstract
The utility model discloses a scrolled ear-shaped hoop, comprising an arced hoop belt, the two ends of the hoop belt are rolled back and fixed to the hoop belt to form a rolled ear structure. The scrolled ear-shaped hoop is characterized in that, the hoop belt is provided with projections formed by bending at the two ends scrolled inward, the projections go through the hoop belt and in cold riveting fixed connection to form scrolled ears. Wherein, one end of the hoop belt is provided with two pairs of projections, the spacing of the pair at the upper part is larger than tat of the lower part, and the projections are obtained by transverse bending of parts of the hoop belt ends. A welding structure in the scrolled ear-shaped hoop is replaced by a cod riveting structure, and the scrolled ear-shaped hoop is advantaged by simple structure, low cost, improvement of connecting strength at the ends of the hoop belt, improvement of use safety, etc.
Description
Technical field
The utility model relates to a kind of clip for the pipeline connection, especially a kind of scroll ear shaped clip.
Background technique
Existing a kind of scroll ear shaped clip, its structure is the band that comprises arc, band is metal material, is fixed to band self after end, the two ends backrush of band and also forms the grasswort structure, slot is set on the grasswort and is equipped with the connection that bolt is realized band two ends grasswort in slot.The for example disclosed a kind of fast loading and unloading of patent CN201121785Y, the capable clip of replaceable bolt type T just belong to this scroll ear shaped yoke configurations.
In this existing scroll ear shaped clip, with band bearing, generally all be to adopt the structure that is welded and fixed after the backrush of band termination.The common fault of welding procedure is rosin joint and solder skip to occur, brings potential safety hazard to quality of product; Take soldering need to add welding equipment on the one hand, increase fixing the input, two need to have the professional of the training of being subjected to operate, the operation user cost is high, because welding changes to the structure of attachment portion, cause corrosion resistance to reduce, get rusty at welding portion easily; Welding belongs to special process, not only equipment investment is large, personnel's change and equipment operating level all can exert an influence to quality of product, to further improve the reliability of product, also need to authenticate through nadcap, can greatly improve the reliability of welding by this authentication, but still can not 100% avoid rosin joint and solder skip, and this certification fee is used and operating cost is high, be spread out in high costs on the product, lack competitiveness by the product price that this authentication is produced, generally only be used in nuclear industry and aerospace field, popular market is beyond affordability.
The model utility content
For above-mentioned deficiency, technical problem to be solved in the utility model is, how to provide a kind of simple in structure, with low cost, can improve band end join strength, improves the scroll ear shaped clip of safety in utilization.
In order to solve the problems of the technologies described above, adopted following technological scheme in the utility model.
A kind of scroll ear shaped clip, the band that comprises arc is fixed to band self after end, the two ends backrush of band and also forms the grasswort structure, and its characteristics are, the end of described band two ends backrush has the projection that bending forms, and described projection is passed band and is fixedly connected to form grasswort from after one's death cold riveting.
In the utility model, the projection of bending is set in the band termination, then the backrush cold riveting is connected to form grasswort.Change the mode that is welded and fixed into cold riveting like this, the potential safety hazard of just effectively having avoided traditional welding technique to exist.The cost of simultaneously cold riveting is lower, so reduced cost of production.Cold riveting can not got rusty because of welding and be destroyed the integrity of material, so guaranteed materials'use life-span and join strength, has improved Security.
As optimization, have two pairs of described projections in a termination of band, be positioned at a pair of spacing of top (depending on nearly bolt direction) greater than being positioned at a pair of of below, projection obtains for the horizontal bending of the part of band termination.This structure can ensure the join strength of cold riveting better, and the manufacturing of being convenient to simultaneously projection forms.
As another optimization, the inside backrush in described band termination forms grasswort.Can at utmost guarantee so the round and smooth degree of clip inner ring, the die of avoiding cold riveting to form impacts the round and smooth degree of clip inner ring.
In sum, the utility model will be in the scroll ear shaped clip welding replace with the structure of cold riveting, possess simple in structurely, with low cost, improve band end join strength, improve the advantages such as safety in utilization.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the utility model perspective view.
Fig. 4 is that Fig. 3 plants I place structure for amplifying schematic representation.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
During implementation, such as Fig. 1-shown in Figure 4, a kind of scroll ear shaped clip, the band 1 that comprises arc, band 1 is metal material, be fixed to band self after end, the two ends backrush of band 1 and also form grasswort 2 structures, slot is set on the grasswort 2 and in slot, is equipped with the connection that bolt 3 is realized band two ends grasswort; Wherein, the end of described band 1 two ends backrush has the projection (adopting label 4 expression projections among the figure by the structure after the cold riveting) that bending forms, and described projection is passed band 1 and is fixedly connected to form grasswort 2 from after one's death cold riveting.A termination at band 1 has two pairs of described projections, is positioned at a pair of spacing of top (depending on nearly bolt direction) greater than being positioned at a pair of of below, and projection obtains for the horizontal bending of the part of band termination.The inside backrush in described band 1 termination forms grasswort.
The utility model solves the clip connected problem by cold riveting, compares with traditional welding and has solved three large technical problems: one, avoided high certification fee usefulness and equipment personnel's Meteorological.Two, greatly improved reliability, three, avoided the decline of the corrosion resistance that welding brings.
Claims (3)
1. scroll ear shaped clip, the band that comprises arc, be fixed to band self after end, the two ends backrush of band and also form the grasswort structure, it is characterized in that, the end of described band two ends backrush has the projection that bending forms, and described projection is passed band and is fixedly connected to form grasswort from after one's death cold riveting.
2. scroll ear shaped clip as claimed in claim 1 is characterized in that, has two pairs of described projections in a termination of band, is positioned at a pair of spacing of top greater than being positioned at a pair of of below, and projection obtains for the horizontal bending of the part of band termination.
