Abstract
The utility model discloses a double -deck holding pin of disconnect -type, including sold inside the country and export trade, the export trade includes four fan -shaped cylinders, four the cylindric lock that the pinhole diameter is equal of external diameter and fastener is constituteed to fan -shaped cylinder, the sold inside the country setting in the export trade, the export trade sets up in the pinhole of fastener, the export trade with pass through threaded connection between the fastener, the hole of export trade is the bell mouth, sold inside the country for with the conical rod of bell mouth adaptation, the export trade with the sold inside the country threaded connection that passes through. The utility model relates to a double -deck holding pin of disconnect -type is through the cooperation sold inside the country and export trade, will sell earlier screw in to pinhole in other areas, realizes tentatively fixing a position, then in will being sold inside the country the screw in export trade, through bell mouth and conical rod's cooperation, the export trade that inflates, makes export trade and fastener realization interference fit to avoid it the unstable condition to appear connecting.
Description
Technical field
The utility model relates to a kind of fixed pin, particularly relates to the double-deck fixed pin of a kind of separated type.
Background technique
Traditional fixed pin directly inserts in pin-and-hole by shank, realizes location, in use, may, under the effect of the vibration of machinery, make to occur space between shank and pin-and-hole, thus occur connecting unstable or that location is failed situation.
Model utility content
The purpose of this utility model is just to provide a kind of separated type double-deck fixed pin to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The double-deck fixed pin of a kind of separated type, comprise domestic and export trade, described export trade comprises four fan-shaped cylinders, the straight pin of the pin-and-hole equal diameters of four described fan-shaped cylinders composition external diameters and fastening piece, is describedly domesticly arranged in described export trade, and described export trade is arranged in the pin-and-hole of fastening piece, be threaded connection between described export trade and described fastening piece, the endoporus of described export trade is cone shape hole, described domestic be the tapered rod with described cone shape hole adaptation, described export trade and to be describedly domesticly threaded connection.
Further, described export trade also comprises connecting rod, positioning block and spring, Curved circular chamber that is vertical and its medial axis is provided with in described fan-shaped cylinder, the two ends in described Curved circular chamber are communicated with by the side of through hole with described fan-shaped cylinder, the through hole that the two ends of described connecting rod are each passed through on two adjacent described fan-shaped cylinders is arranged in its Curved circular chamber, and be fixedly connected with the described positioning block be arranged in described Curved circular chamber, be sleeved on outside described connecting rod between the end face that described spring is arranged on described fixed block and described Curved circular chamber.
Preferably, the diameter in described Curved circular chamber is greater than the diameter of described through hole, and the diameter of described through hole is greater than the diameter of described connecting rod, and described spring is in half compressive state.
Preferably, same described fan-shaped cylinder is provided with multiple Curved circular chamber.
The beneficial effects of the utility model are:
The double-deck fixed pin of a kind of separated type of the utility model is by domestic and cooperation that is export trade, first export trade is screwed in in pin-and-hole, realize Primary Location, then by domestic screw-in export trade, by the cooperation of cone shape hole and tapered rod, swell export trade, makes export trade and fastening piece realize interference fit, thus avoid it to occur connecting unstable situation.
Accompanying drawing explanation
Fig. 1 is the scheme of installation of the double-deck fixed pin of a kind of separated type described in the utility model;
Fig. 2 is the plan view of the double-deck fixed pin of a kind of separated type described in the utility model;
Fig. 3 is the sectional view of the double-deck fixed pin of a kind of separated type described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the double-deck fixed pin of a kind of separated type of the utility model, comprise domestic 2 and export trade 1, domestic 2 are arranged in export trade 1, export trade 1 is arranged in the pin-and-hole of fastening piece 3, is threaded connection between export trade 1 and fastening piece 3, and the endoporus of export trade 1 is cone shape hole, domestic 2 is the tapered rod with cone shape hole adaptation, and export trade 1 and domestic 2 is threaded connection.
As shown in Figures 2 and 3, export trade 1 comprises connecting rod 13, positioning block 15, spring 16 and four fan-shaped cylinders 11, four fan-shaped cylinders 11 form the straight pin of the pin-and-hole equal diameters of external diameter and fastening piece 3, Curved circular chamber 12 that is vertical and its medial axis is provided with in fan-shaped cylinder 11, the two ends in Curved circular chamber 12 are communicated with the side of fan-shaped cylinder 11 by through hole 14, the through hole 14 that the two ends of connecting rod 13 are each passed through on two adjacent fan-shaped cylinders 11 is arranged in its Curved circular chamber 12, and be fixedly connected with the positioning block 15 be arranged in Curved circular chamber 12, be sleeved on outside connecting rod 13 between the end face that spring 16 is arranged on fixed block and Curved circular chamber 12, the diameter in Curved circular chamber 12 is greater than the diameter of through hole 14, the diameter of through hole 14 is greater than the diameter of connecting rod 13, spring 16 is in half compressive state, same fan-shaped cylinder 11 is provided with multiple Curved circular chamber 12.
The working principle of the double-deck fixed pin of a kind of separated type of the utility model is as follows:
Because spring 16 is in compressive state, apply towards the active force in the elongation line direction of connecting rod 13 to positioning block 15, opposition makes the side laminating of two adjacent fan-shaped cylinders 11, thus makes four fan-shaped cylinders 11 be connected to become a cylindrical body by connecting rod 13.
In use, first export trade 1 is screwed in in pin-and-hole, screw in domestic 2 in export trade 1, because the endoporus of export trade 1 is cone shape hole, domestic 2 is tapered rod again, continue to rotate after being threaded to certain position when domestic 2, make spring 16 continue compression, the side of two adjacent segmental cylindrical is separated, and makes the external diameter of export trade 1 become large, thus make to realize interference fit between export trade 1 and fastening piece 3, make it connect closely.
When needs disassembly-type, screw out domestic 2, export trade 1 under the action of the spring 16, returns to the state of segmental cylindrical side laminating, the external diameter of export trade 1 is diminished, is convenient to export trade 1 and screws out in pin-and-hole.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion made according to the technical solution of the utility model, all falls within protection domain of the present utility model.
