The technical effects of the utility model reside in that: the product of the utility model is simple in structure, reasonable, the connecting piece adopts the slice structure, in the manufacturing process, can effective save material, reduce cost, the comparatively convenient and fast of slice connecting piece processing simultaneously.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings.
In the figure 1, the connecting device comprises a connecting head 1, an upper cross rod 1-1, a lower seat plate 1-2, a connecting hole 2, a threaded portion 3, a guide portion 3-1, a limiting retaining shoulder 3-2, an arc groove 3-3, a step 3-4, a transition portion 4 and the like.
As shown in figure 1, the utility model relates to a spring connector, including flaky connecting piece body, the connecting piece body includes screw thread portion 3 and the connector 1 of a body coupling in screw thread portion 3 upper end, set up connecting hole 2 on the connector 1, screw thread portion 3 evenly arranges a plurality of circular arc groove 3-3 along length direction respectively along the width direction both sides, and screw thread portion 3's lower extreme sets up the guide part 3-1 of a body coupling.
The threaded part 3 is connected with the connecting head 1 through a transition part 4, and the upper part of the threaded part 3 is provided with a step 3-4 corresponding to the lower part of the transition part 4. In practice, the width at the transition 4 is smaller than the width of the upper and lower parts connected thereto, i.e. a groove is formed at the transition 4.
The upper part of the thread part 3 is provided with a limiting stop shoulder 3-2, and the diameter of the thread part 3 corresponding to the limiting stop shoulder 3-2 is larger than that of the thread part 3 corresponding to the arc groove 3-3.
The guide part 3-1 is in a right trapezoid shape, and when the utility model is used for connecting a spring, the guide part 3-1 plays a good guiding role so as to realize convenient, quick, accurate and reliable connection.
The connector 1 comprises an upper cross rod 1-1 and a lower seat plate 1-2 which are integrally connected, the width of the upper cross rod 1-1 is larger than that of the lower seat plate 1-2, and the connecting hole 2 is arranged on the lower seat plate 1-2. The upper cross rod 1-1 can be effectively matched with other auxiliary parts during working.
The utility model has the advantages of simple and reasonable product structure, the processing degree of difficulty that exists to the connecting axle that is used for connecting the column spring among the prior art is big, the many problem of materials carries out the pertinence and improves, adopts the lamellar structure, and the connecting piece of this kind of structure is connected through the hole screw-thread fit of screw thread portion 3 with the spring when using, when connecting, the utility model discloses the screw thread portion 3 normal running fit of the connecting piece of product is connected in the hole of column spiral wound spring, and 3-2 support shoulders 3 of spacing fender of screw thread portion 3 lean on in the spring up end, and spring coupling connects this moment and targets in place, then will the utility model discloses connecting hole 2 on product upper portion is connected with the corresponding connecting piece in door body both sides to realize the reliable.
