Abstract

The utility model discloses a fixing device capable of shifting on a bushing, which is mainly characterized in that a penetrative through hole matching correspondingly to the bushing is arranged in a stud body; both end surfaces of the through hole are provided with conical surfaces; the stud body (3) is provided with external screw threads and nuts of the through hole 2, 4 matching with the external screw threads; rubber fastening rings holding the bushing are arranged between the conical surfaces of the through hole and the bushing, and the sizes of the rubber fastening rings are adaptive to the conical surfaces of the through hole and the bushing; the inner diameters of the through holes of the screw nuts of the through hole 2, 4 are longer than the outer diameter of the bushing 1, and are less than or equal to the diameter of the through hole of the stud body (3) so as to form an end cap. The fixing device with the structure has the advantages of convenient adjustment and shift, larger fixing force, and material saving. Moreover, the external surface of the bushing (1) can not be damaged, which does not influence the beautiful appearance.

Description

The fixing device that can on sleeve pipe, move

One, technical field

The utility model relates to a kind of fixing device, especially relates to a kind of fixing device that can move on sleeve pipe.

Two, background technique

Selling the fixing device of generally using with everybody that can move on sleeve pipe in the market mostly is to overlap a pipe box again in the cover tube outside, offer threaded hole in the radial direction of this pipe box wall, by tightening of screw pipe box is connected with fixing on sleeve pipe then, on pipe box, can connect other members more then, this structure is because the area of contact of screw and sleeve pipe and pipe box is less, stressed more concentrated, therefore require the intensity of material higher, and easy damaged tightens up the outer wall of outer sleeve, especially can stay certain scar on outer walls of the pipes of light to those surfaces and influences that it is attractive in appearance.

Three, model utility content

Technical problem to be solved in the utility model is: can on pipe, move can not damage its tube-surface again and the bigger bushing type of the power that tightens up be connected and fixed device.

The technical solution of the utility model is such: as shown in Figure 1, the fixing device that this can move on sleeve pipe, comprise spiro column 3, establish perforation in this spiro column 3 with the sleeve pipe 1 corresponding through hole that cooperates, these through hole two ends are provided with the conical surface, this through hole mid diameter is suitable for being slidingly matched with sleeve pipe 1, the through

hole nut

2 and 4 that described spiro column 3 is provided with outside thread and cooperates with it; Between the described through hole two end conical surfaces and sleeve pipe, be provided with elasticity fastening ring 5 and 6, the inclined-plane of the internal diameter of this elasticity fastening ring and external diameter and described through hole and sleeve pipe 1, suitable and hold tightly and hold sleeve pipe 1; Thereby the through hole internal diameter of described through

hole nut

2 and 4 is slightly larger than the external diameter of sleeve pipe 1 and forms an end cap smaller or equal to the internal diameter of spiro column 3 through holes.The angle of inclination of the described conical surface is preferably 15 °～45 °.

Owing to adopted above technological scheme, the utlity model has following beneficial effect: lay down load, unclamp nut, slippage elasticity fastening ring and again locking nut just can adjust the position that is connected and fixed.And because the elasticity fastening ring that has adopted materials such as rubber to make, area of contact is increased, and become flexible fixedly connected, therefore, it is strong to be connected and fixed power, thereby the requirement of strength that can reduce material under same fixed power is saved material, and the outer surface of sleeve pipe can not damage, and has application promise in clinical practice and economic benefit.

Four, description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A place partial enlarged drawing of Fig. 1.

Among the figure: the 1st, sleeve pipe, 2 and 4 is through hole nuts, the 3rd, spiro column, 5 and 6 is elasticity fastening rings.

Five, embodiment

An embodiment of the present utility model is: as depicted in figs. 1 and 2, in spiro column (3), establish perforation with the sleeve pipe 1 corresponding through hole that cooperates, these through hole two ends are provided with the conical surface, mid diameter is suitable for being slidingly matched with sleeve pipe 1, the through

hole nut

2 and 4 that described spiro column 3 is provided with outside thread and cooperates with it, between the through hole two end conical surfaces and sleeve pipe, be provided with elasticity fastening ring 5 and 6,6 internal diameter of this elasticity fastening ring 5 and sleeve pipe 1 are suitable and hold sleeve pipe 1 tightly, and this elasticity fastening ring 5 and 6 just in time is placed on the conical surface of spiro column 3.Described

nut

2 and 4 through hole internal diameter be slightly larger than sleeve pipe 1 external diameter and less than the internal diameter of spiro column 3 through holes, thereby form an end cap, this end cap just in time covers elasticity fastening ring 5 and 6 and make it to compress.The angle of inclination of the through hole two end conical surfaces of described spiro column 3 is respectively 15 ° and 30 °.The o type fastening ring that described elasticity fastening ring 5 and 6 is made for rubber.

Embodiment 2:

As shown in Figure 1, described elasticity fastening ring 6 is the plastics fastening ring on the stronger band inclined-plane of plasticity, and the angle of inclination on the set inclined-plane that is inverted cone is consistent in the tilt angle on its inclined-plane and spiro column 3 through holes, and all the other are identical with embodiment 1.

Embodiment 3:

As shown in Figure 1, described spiro column 3 is made the spiro column of band cantilever, and other mechanisms are installed on this cantilever.All the other are identical with embodiment 1.

Claims

1, a kind of fixing device that can on sleeve pipe, move, comprise spiro column (3), it is characterized in that: the corresponding through hole that cooperates of establishing perforation in the described spiro column (3) with sleeve pipe (1), these through hole two ends are provided with the conical surface, the diameter of this through hole is suitable for being slidingly matched with sleeve pipe (1), the through hole nut (2,4) that described spiro column (3) is provided with outside thread and cooperates with it; Be provided with elasticity fastening ring (5,6) between the described through hole two end conical surfaces and sleeve pipe, the inclined-plane of the internal diameter of this elasticity fastening ring and external diameter and described through hole and sleeve pipe (1) are suitable and embrace sleeve pipe (1); The through hole internal diameter of described through hole nut (2,4) be slightly larger than sleeve pipe (1) external diameter and smaller or equal to spiro column (3) thus in establish through hole internal diameter form an end cap.

2, the fixing device that can move on sleeve pipe according to claim 1 is characterized in that: the described angle of inclination that is the inverted cone inclined-plane is 15 °～45 °.
