The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further details.

The rifle head of the utility model preferred embodiment one as shown in Figures 1 and 2 and the structural representation of soft cover, the rifle head 1 of this preferred embodiment one is threaded with rifle body (not shown) by threaded portion 4, rifle head 1 is a hollow tubular structure, and the cavity 5 of rifle head 1 axially is provided with and connects the integral body of rifle head 1 along it.When manufacturing was finished or used, the soft cover 10 of this preferred embodiment one was set in rifle head 1 outside.Soft cover 10 also is a hollow tubular structure substantially, and it is made by having certain flexible material, for example rubber, sponge etc.The cavity 50 of soft cover 10 is sleeved on the outside of rifle head 1, and its front end extends to the front end of rifle head 1, the extension is that hollow tubular structure is so that rifle head 1 and external communications, also be through hole 20 and through hole 2 corresponding settings, the diameter of through hole 20 is less than the diameter of cavity 50, and the diameter of through hole 2 is also less than the diameter of cavity 5.The outer wall of rifle head 1 is provided with the groove 3 that prevents soft cover 10 landings, and soft cover 10 has certain elasticity, thereby therefore corresponding with groove 3 part can embed and can effectively prevent the landing from the rifle head 1 of soft cover 10 in the groove 3.In this preferred embodiment, groove 3 is around the lateral wall setting of rifle head 1, and in other embodiments, groove 3 can also can be the lines of projection for discontinuous.

The soft cover 10 of this preferred embodiment one can be avoided swiping when drifting dust and contact object with it, for example at vehicle maintenance and repair enterprise, uses this preferred embodiment and can avoid the interior trim of rifle body scraping automobile, glass etc. once carrying out drifting dust.

Other embodiment that do not comprise soft cover can be applied in the occasion that some are not easy to be worn, the workshop of some factory for example, the rifle head is because of often contacting with other objects, wearing and tearing are very fast, when needing to change, new rifle head directly is installed is got final product, avoided the wearing and tearing of rifle body and changed the application cost problem of higher that the rifle body is produced.

The structural representation of the rifle head of the utility model preferred embodiment two as shown in Figure 3 and Figure 4 and rifle head core, the rifle head 1 of this preferred embodiment two is threadedly connected to the end of rifle body (not shown) by its threaded portion 4, rifle head 1 is a hollow tubular structure, the rifle head core 100 of one hollow is set in its cavity 5, and the threaded portion 6 of rifle head 1 is connected with the threaded portion 60 of rifle head core 100.Rifle head core 100 is not a tubular structure, and the inner end opening of the cavity 50 of rifle head core 100 is a through hole 500.Conical structure 510 is positioned at the inboard end of rifle head core 100, and with a shrinkage hole 51 corresponding settings of rifle head 1 inside, the diameter of shrinkage hole 51 is less than the maximum gauge of the cross section of conical structure 510, as the through hole 500 of cavity 50 inner end openings between threaded portion 60 and conical structure 510.

When assembling or application, rifle head core 100 is threaded with the threaded portion 6 of rifle head 1 by its threaded portion 60, therefore rifle head core 100 can move in the 1 inner rotation of rifle head, thereby can control the switching degree of conical structure 510 and shrinkage hole 51, and when using, the circulation passage of wind is cavity 50, through hole 500 and shrinkage hole 51.Wind-force when therefore controlling length that conical structure 510 gos deep into shrinkage hole 51 and can control drifting dust.Because the maximum gauge of the cross section of conical structure 510 is greater than the diameter of shrinkage hole 51, so the wind-force minimum can be with drifting dust the time is controlled to be zero.

Make it to move in rifle head 1 in order to rotate rifle head core 100 easily, also be provided with a figure line structure 101 on the rifle head core 100, this figure line structure 101 is arranged at the outside of threaded portion 60, and the figure line on it is the axially extended concave and convex stripe along rifle head core 100.In other embodiments, the structural figure line of figure line can be densely covered projection or irregular decorative pattern etc.

By analyzing as can be known, this preferred embodiment two is fit to be applied to the occasion that needs are often adjusted wind-force very much, and its adjusting range can reach zero to maximum.

As known by the technical knowledge, the utility model can be realized by other the embodiment that does not break away from its spiritual essence or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all just illustrates, and is not only.All in the utility model scope or the change that is being equal in the scope of the present utility model all be included in the utility model.
