Abstract
The utility model discloses a connecting structure of a plastic screw ring and a metal inverse horn-shaped barrel body of a heat preservation container. The connecting structure comprises the barrel body, the plastic screw ring, a bottom, a bottom screw and a glass lining, and is characterized in that the plastic screw ring is clamped on a flange on the lower part of the barrel body through utilizing plastic deformation; rectangular threads are formed on the inner wall of the plastic screw ring; the bottom is connected with the barrel body through the rectangular threads on the screw ring; threads are formed on the inner wall of a center hole in the bottom; and the bottom screw is screwed into through the threads and the glass lining can be ejected and positioned. The connecting structure has the advantages that the design is novel, the plastic screw ring is directly connected with the barrel body through the plastic deformation of the plastic screw ring, the assembly is simple and convenient, the connection is reliable, parts are relatively few, and the manufacture cost is greatly reduced.
Description
Technical field
The utility model relates to a kind of cool-bag, particularly the connecting structure of a kind of plastics eyebolt of cool-bag and the metal stack shell of falling loudspeaker.
Background technique
Since be subjected to Shooting Technique, Mould Machining, the restriction that adds technology of assembly technology and metalwork, conventional eyebolt and the connecting structure of the metal stack shell of falling loudspeaker are:
1) connecting of eyebolt and the stack shell of falling loudspeaker adopts two sided plaster to connect, and be specific as follows: earlier two sided plaster is sticked on eyebolt and the outer wall that stack shell contact, eyebolt is out of shape puts into stack shell again, with hand eyebolt is pasted abdomen bottom the stack shell at last.Utilize the viscous force of two sided plaster, eyebolt just can not be drawn back, so that the end can be tightened on the stack shell smoothly.This structure assembling is very loaded down with trivial details, can only be hand-manipulated when pasting two sided plaster, and the man-hour of usefulness is a lot, and assembly process process is poor, and adopts two sided plaster to connect, and has not only increased the cost of two sided plaster, has also increased process cost.
2) adopt spot welding technology to connect, the eyelet of a cylinder annular is weldingly fixed on the end opening of metal loudspeaker stack shell, eyebolt and its cylindrical enclosure interference fit, the end utilize the tension force of plastics eyebolt to make that eyebolt can not be drawn back when the end was installed, so that can be tightened on the stack shell smoothly.But this structure has increased the welding process of bottom metal circle in stack shell processing, has also increased processing and the cost of material of eyelet, and the technology by spot welding, can make the outer surface of the bottom surface of stack shell solder joint occur, influences outward appearance.
Summary of the invention
The purpose of this utility model is at the defective that exists in the prior art, has structurally done some and has optimized, and a kind of connecting structure of plastics eyebolt and the metal stack shell of falling loudspeaker of cool-bag is provided.The utility model comprises: stack shell, plastics eyebolt, the end, end screw, glass courage, it is characterized in that utilizing the plastic deformation of plastics eyebolt that it is stuck on the flange of the metal stack shell of falling loudspeaker bottom, the inwall of plastics eyebolt is provided with square threaded form, the end, connect as one by the square threaded form on the plastics eyebolt and the metal stack shell of falling loudspeaker, the inwall of end center hole is provided with screw thread, and end screw through being threaded at the end.Behind the glass courage of packing into, the end that will revolve end screw again by with plastics eyebolt inwall on square threaded form the end, be tightened on metal fall on one's body the Megaphone, by screwing the end screw glass courage is held out against again.
The outer wall of described plastics eyebolt is provided with an annular groove, and the plastics eyebolt blocks the flange of the metal stack shell of falling loudspeaker by annular groove.The flange that utilizes annular groove on the plastics eyebolt to block the metal stack shell of falling loudspeaker do not allow the plastics eyebolt retreat, and guaranteed square threaded form at the end and the smooth interlock of rectangle screw on the plastics eyebolt like this.
The utility model has the advantages that to count and establish novelty, utilize the plastic deformation of plastics eyebolt directly to connect with the metal stack shell of falling loudspeaker, assembling is simple, convenient, connects reliably, and part is less relatively, thereby has reduced manufacture cost greatly.
Description of drawings
Fig. 1 sectional structure schematic representation of the present utility model.
Among the figure: 1 glass courage, 2 stack shells, 3 plastics eyebolts, 4 ends, 5 end screws.
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, the outer wall of present embodiment plastics eyebolt 3 is provided with an annular groove, and plastics eyebolt 3 blocks the flange of the metal stack shell of falling loudspeaker 2 by annular groove.The flange that annular groove on the plastics eyebolt 3 blocks the metal stack shell of falling loudspeaker 2 does not allow plastics eyebolt 3 retreat, and has guaranteed square threaded form at the end 4 and the smooth interlock of rectangle screw on the plastics eyebolt 3 like this.Utilize the plastic deformation of plastics eyebolt 3 that it is stuck on the flange of the metal stack shell of falling loudspeaker 2 bottoms, the inwall of plastics eyebolt 3 is provided with square threaded form, the end 4, connect as one by the square threaded form on the plastics eyebolt 3 and the metal stack shell of falling loudspeaker 2, the ends 4 inwall of center hole is provided with screw thread, and end screw 5 through being threaded at the end 4.Behind the glass courage 1 of packing into, the end 4 that will revolve end screw 5 again by with plastics eyebolt 3 inwalls on square threaded form the end 4, be tightened on the metal stack shell of falling loudspeaker 2, by screwing end screw 5 glass courage 1 is held out against again.
Claims (2)
1. the connecting structure of the plastics eyebolt of a cool-bag and the metal stack shell of falling loudspeaker, comprise: stack shell, plastics eyebolt, the end, end screw, glass courage, it is characterized in that the plastics eyebolt is installed on the flange of stack shell bottom, the inwall of plastics eyebolt is provided with square threaded form, the end, connect as one by the square threaded form on the eyebolt and stack shell, the inwall of end center hole is provided with screw thread, and end screw is through being threaded into and the glass courage being held out against the location.
